    Lawyers generally explain legal development by looking at explicit amendments to statutory law and modifications in judicial practice. As far as the latter are concerned, leading cases occupy a special place. This article empirically studies the process in which certain cases become leading cases....... Our analysis focuses on Les Verts, a case of considerable fame in EU law, closely scrutinising whether it contains inherent leading case material. We show how the legal relevance of a case can become “embedded” in a long process of reinterpretation by legal actors, and we demonstrate that the actual...

    Lead boro-telluro-phosphate glasses containing 0.05 to 2.0 wt% of Eu3+ ions were prepared through melt quenching technique. Structural characteristics of title glasses were identified through XRD, FTIR and Raman studies. The optical properties of the prepared glasses were studied using UV-Vis-NIR absorption and photoluminescence spectra. From the resultant spectra, we have obtained the bonding parameters (δ), nephelauxetic ratio (β), direct and indirect band gaps and Urbach energy (ΔE) values. A deep red luminescence due to 5D0 → 7F2 transition of Eu3+ ions could be observed for the title glasses. The local site symmetry around the Eu3+ ions and the degree of Eu3+-O2- covalence were assessed from the luminescence intensity ratio of 5D0 → 7F2/5D0 → 7F1 transitions. Judd-Ofelt intensity parameters, calculated from the luminescence spectra, were used to estimate the radiative parameters like transition probability (A), branching ratio (βexp, βcal) and stimulated emission cross-section (σPE) concerning the 5D0 → 7FJ (J = 0, 1, 2, 3 and 4) transitions. The important laser parameters, gain bandwidth and optical gain are also estimated. The decay curves associated with the transition from 5D0 state was found to be single-exponential at all Eu3+ ion concentrations. CIE colour coordinates and colour purity of the prepared glasses were estimated from the CIE chromaticity diagram.

  9. Spacecraft Jitter Attenuation Using Embedded Piezoelectric Actuators

    Belvin, W. Keith

    1995-01-01

    Remote sensing from spacecraft requires precise pointing of measurement devices in order to achieve adequate spatial resolution. Unfortunately, various spacecraft disturbances induce vibrational jitter in the remote sensing instruments. The NASA Langley Research Center has performed analysis, simulations, and ground tests to identify the more promising technologies for minimizing spacecraft pointing jitter. These studies have shown that the use of smart materials to reduce spacecraft jitter is an excellent match between a maturing technology and an operational need. This paper describes the use of embedding piezoelectric actuators for vibration control and payload isolation. In addition, recent advances in modeling, simulation, and testing of spacecraft pointing jitter are discussed.

    Full Text Available The current paper combines the results of two Sixth Framework Program EU research projects aimed at developing and testing methods for integrated assessment of health risks from environmental stressors, i.e. the INTARESE and the HEIMTSA project, both of which covered a case study on environmental lead. The INTARESE case study on lead in Europe was meant to illustrate the use of the Integrated Monitoring Framework Strategy to assess the health outcome of environmental pollution by evaluating the associations between lead in various environmental compartments (air, soil, dust, drinking water and diet and lead concentrations in blood (B-Pb for various age-related sub-populations. The case study was aimed to investigate whether environmental, exposure and biomonitoring data at general population level, covering all EU member states, could be integrated. The HEIMTSA case study on the other hand involved the full chain assessment from policy drivers to health effect quantification of lead exposure through locally produced food on loss of IQ in pre-school children at the population level across the EU-27, including monetary valuation of the estimated health impact. Main policy scenarios cover the period from 2000 to 2020 and include the most important Community policy developments expected to affect the environmental release of lead (Pb and corresponding human exposure patterns. Three distinct scenarios were explored: the emission situation based on 2000 data, a business-as-usual scenario (BAU up to 2010 and 2020 and a scenario incorporating the most likely technological change expected (Most Feasible Technical Reductions, MFTR in response to current and future legislation. Analysing environmental data, significant correlations were found between B-Pb and the concentrations of Pb in air and diet. The significant decrease of the Pb in air over time from 0.31 μg/m3 (P95: 0.94; n=98 prior to 1990 to 0.045 μg/m3 (P95:0.11; n=256 in 2007 (latest

    Full Text Available The EU has always been at the forefront of tackling environmental issues. This paper responds to the EU‟s „call for action‟ towards addressing the issue of climate change – a key priority for the European Commission in the 2030 policy perspective. The topic is addressed through a focus group that seeks to identify and disseminate possible approaches through which the EU can leverage its international „actorness‟ in negotiating a straightforward and binding global agreement for action in climate change mitigation. The focus group involves a sample of students, beneficiaries of an environmentally focused Jean Monnet teaching module (TAG-EU. The diverse academic background of the students (coming from social, natural and exact sciences provides a unique point of view in tackling this ardent issue and can bring valuable and interdisciplinary contributions to the discussion on climate change action.

  1. Effect of jitter on an imaging FTIR spectrometer

    Energy Technology Data Exchange (ETDEWEB)

    Bennett, C. L., LLNL

    1997-04-01

    Line of sight (LOS) jitter produces temporal modulations of the signals which are detected in the focal plane of a temporally modulated imaging Fourier Transform Spectrometer. A theoretical treatment of LOS jitter effects is given, and is compared with the results of measurements with LIFTIRS1 (the Livermore Imaging Fourier Transform InfraRed Spectrometer). The identification, isolation, quantification and removal of jitter artifacts in hyperspectral imaging data by means of principal components analysis is discussed. The theoretical distribution of eigenvalues expected from principal components analysis is used to determine the level of significance of spatially coherent instrumental artifacts in general, including jitter as a representative example. It is concluded that an imaging FTIR spectrometer is much less seriously impacted by a given LOS jitter level than a non imaging FTIR spectrometer.

  3. Spectrally Undiscerned Isomers Might Lead to Erroneous Determination of Water Exchange Rates of paraCEST Eu(III) Agents.

    2017-07-17

    We report a detailed study of the solution structure and water exchange rate of a Eu(III) complex with the cyclen-based ligand L 1 , containing (S)-2-(2-acetamido)-3-(4-(trifluoromethyl)phenyl)propanoate pendant arms at positions 1 and 7 of the cyclen ring and acetylglycinate pendants at positions 4 and 10. The EuL 1 complex was characterized by a combination of NMR and luminescence spectroscopy and density functional theory (DFT) calculations. The chemical exchange saturation transfer (CEST) spectra obtained at different temperatures and saturation powers present a CEST signal attributed to the coordinated water molecule. However, the spectra recorded at low temperatures (10 °C) and low saturation powers revealed the presence of two different species with coordinated water molecules having very similar chemical shifts. Determination of the water exchange rates of the coordinated water molecules was carried out by using the Bloch four-pool model that accounts for the presence of these isomers, and this model was compared to conventional methods for CEST quantification, namely the Omega plot and QUESP (quantification of exchange rate as a function of saturation power), which assume the presence of a single CEST active species. The results indicated that only the four-pool Bloch equations provide reasonable water exchange rates and activation parameters. Solution NMR studies and DFT calculations indicated that the two isomers present in solution correspond to the SS-Δ(λλλλ) and SS-Λ(δδδδ) isomers, which present capped square-antiprismatic (SAP) coordination environments. Additional NMR studies on the EuL 2 and EuL 3 complexes, which present four (S)-2-(2-acetamido)-3-(4-(trifluoromethyl)phenyl)propanoate or acetylglycinate pendant arms, respectively, confirm the results obtained for EuL 1 .

    Applications with optical atomic clocks and precision timing often require the transfer of optical frequency references to the electrical domain with extremely high fidelity. Here we examine the impact of photocarrier scattering and distributed absorption on the photocurrent noise of high-speed photodiodes when detecting ultralow jitter optical pulses. Despite its small contribution to the total photocurrent, this excess noise can determine the phase noise and timing jitter of microwave signals generated by detecting ultrashort optical pulses. A Monte Carlo simulation of the photodetection process is used to quantitatively estimate the excess noise. Simulated phase noise on the 10 GHz harmonic of a photodetected pulse train shows good agreement with previous experimental data, leading to the conclusion that the lowest phase noise photonically generated microwave signals are limited by photocarrier scattering well above the quantum limit of the optical pulse train.

  5. Does EU ETS lead to emission reductions through trade? The case of the Swedish emissions trading sector participants

    International Nuclear Information System (INIS)

    Sandoff, Anders; Schaad, Gabriela

    2009-01-01

    The first trading period of the European Emissions Trading Scheme (EU ETS) has recently come to an end. The experiences of the actors in the trading sector will be of great importance in evaluating the aim and direction of this 'Grand Policy Experiment'. This paper gives an account of the attitudes and actions of the companies included in the Swedish emissions trading sector after about 15 months of experience with the system. The data are based on a study commissioned by the Swedish Environmental Protection Agency, and is a comprehensive survey that encompasses all companies operating installations included in the Swedish Emission Trading Registry. However, the results point in a somewhat disquieting direction. Although the Swedish companies have shown significant interest in reducing emissions, this survey indicates that this is done without close attention to the pricing mechanism of the market-based instruments. If this praxis is widespread within the European trading sector, it can have a serious negative effect on the efficiency of the system.

  6. Robust real-time change detection in high jitter.

    Energy Technology Data Exchange (ETDEWEB)

    Simonson, Katherine Mary; Ma, Tian J.

    2009-08-01

    A new method is introduced for real-time detection of transient change in scenes observed by staring sensors that are subject to platform jitter, pixel defects, variable focus, and other real-world challenges. The approach uses flexible statistical models for the scene background and its variability, which are continually updated to track gradual drift in the sensor's performance and the scene under observation. Two separate models represent temporal and spatial variations in pixel intensity. For the temporal model, each new frame is projected into a low-dimensional subspace designed to capture the behavior of the frame data over a recent observation window. Per-pixel temporal standard deviation estimates are based on projection residuals. The second approach employs a simple representation of jitter to generate pixelwise moment estimates from a single frame. These estimates rely on spatial characteristics of the scene, and are used gauge each pixel's susceptibility to jitter. The temporal model handles pixels that are naturally variable due to sensor noise or moving scene elements, along with jitter displacements comparable to those observed in the recent past. The spatial model captures jitter-induced changes that may not have been seen previously. Change is declared in pixels whose current values are inconsistent with both models.

  7. E-model MOS Estimate Improvement through Jitter Buffer Packet Loss Modelling

    Directory of Open Access Journals (Sweden)

    Adrian Kovac

    2011-01-01

    Full Text Available Proposed article analyses dependence of MOS as a voice call quality (QoS measure estimated through ITU-T E-model under real network conditions with jitter. In this paper, a method of jitter effect is proposed. Jitter as voice packet time uncertainty appears as increased packet loss caused by jitter memory buffer under- or overflow. Jitter buffer behaviour at receiver’s side is modelled as Pareto/D/1/K system with Pareto-distributed packet interarrival times and its performance is experimentally evaluated by using statistic tools. Jitter buffer stochastic model is then incorporated into E-model in an additive manner accounting for network jitter effects via excess packet loss complementing measured network packet loss. Proposed modification of E-model input parameter adds two degrees of freedom in modelling: network jitter and jitter buffer size.

    2014-01-01

    For the commissioning and operation of modern particle accelerators, automated error detection and diagnostics methods are becoming increasingly important. In this paper, we present two such methods, which are capable of localising sources of beam offset jitter with a combination of correlation studies and so called degree of freedom plots. The methods were applied to the ATF2 beam line at KEK, where one of the major goals is the reduction of the beam offset jitter. Results of this localisation are shown in this paper. A big advantage of the presented method is its high robustness especially to varying optics parameters. Therefore, we believe that the developed beam offset jitter localisation methods can be easily applied to other accelerators.

    1985-01-01

    Multimodule pulsed power accelerators typically require high module reliability and nanosecond regime simultaneity between modules. Energy storage using bipolar Marx generators can meet these requirements. Experience gained from computer simulations and the development of the DEMON II Marx generator has led to a fundamental understanding of the operation of these multistage devices. As a result of this research, significant improvements in erection time jitter and reliability have been realized in multistage, bipolar Marx generators. Erection time jitter has been measured as low as 2.5 nanoseconds for the 3.2MV, 16-stage PBFA I Marx and 3.5 nanoseconds for the 6.0MV, 30-stage PBFA II (DEMON II) Marx, while maintaining exceptionally low prefire rates. Performance data are presented from the DEMON II Marx research program, as well as discussions on the use of computer simulations in designing low-jitter Marx generators

  12. High reliability low jitter 80 kV pulse generator

    International Nuclear Information System (INIS)

    Savage, Mark Edward; Stoltzfus, Brian Scott

    2009-01-01

    Switching can be considered to be the essence of pulsed power. Time accurate switch/trigger systems with low inductance are useful in many applications. This article describes a unique switch geometry coupled with a low-inductance capacitive energy store. The system provides a fast-rising high voltage pulse into a low impedance load. It can be challenging to generate high voltage (more than 50 kilovolts) into impedances less than 10 (Omega), from a low voltage control signal with a fast rise time and high temporal accuracy. The required power amplification is large, and is usually accomplished with multiple stages. The multiple stages can adversely affect the temporal accuracy and the reliability of the system. In the present application, a highly reliable and low jitter trigger generator was required for the Z pulsed-power facility [M. E. Savage, L. F. Bennett, D. E. Bliss, W. T. Clark, R. S. Coats,J. M. Elizondo, K. R. LeChien, H. C. Harjes, J. M. Lehr, J. E. Maenchen, D. H. McDaniel, M. F. Pasik, T. D. Pointon, A. C. Owen, D. B. Seidel, D. L. Smith, B. S. Stoltzfus, K.W. Struve, W.A. Stygar, L.K. Warne, and J. R. Woodworth, 2007 IEEE Pulsed Power Conference, Albuquerque, NM (IEEE, Piscataway, NJ, 2007), p. 979]. The large investment in each Z experiment demands low prefire probability and low jitter simultaneously. The system described here is based on a 100 kV DC-charged high-pressure spark gap, triggered with an ultraviolet laser. The system uses a single optical path for simultaneously triggering two parallel switches, allowing lower inductance and electrode erosion with a simple optical system. Performance of the system includes 6 ns output rise time into 5.6 (Omega), 550 ps one-sigma jitter measured from the 5 V trigger to the high voltage output, and misfire probability less than 10 -4 . The design of the system and some key measurements will be shown in the paper. We will discuss the design goals related to high reliability and low jitter. While

    Full Text Available We present measurements and analysis of the longitudinal timing jitter of a Beijing Electron Positron Collider (BEPCII linear accelerator electron gun. We simulated the longitudinal jitter effect of the gun using PARMELA to evaluate beam performance, including: beam profile, average energy, energy spread, and XY emittances. The maximum percentage difference of the beam parameters is calculated to be 100%, 13.27%, 42.24% and 65.01%, 86.81%, respectively. Due to this, the bunching efficiency is reduced to 54%. However, the longitudinal phase difference of the reference particle was 9.89°. The simulation results are in agreement with tests and are helpful to optimize the beam parameters by tuning the trigger timing of the gun during the bunching process.

    We find that the remnant of supernova (SN) 1987A shares some morphological features with four supernova remnants (SNRs) that have signatures of shaping by jets, and from that we strengthen the claim that jets played a crucial role in the explosion of SN 1987A. Some of the morphological features appear also in planetary nebulae (PNe) where jets are observed. The clumpy ejecta bring us to support the claim that the jittering jets explosion mechanism can account for the structure of the remnant of SN 1987A, i.e., SNR 1987A. We conduct a preliminary attempt to quantify the fluctuations in the angular momentum of the mass that is accreted on to the newly born neutron star via an accretion disk or belt. The accretion disk/belt launches the jets that explode core collapse supernovae (CCSNe). The relaxation time of the accretion disk/belt is comparable to the duration of a typical jet-launching episode in the jittering jets explosion mechanism, and hence the disk/belt has no time to relax. We suggest that this might explain two unequal opposite jets that later lead to unequal sides of the elongated structures in some SNRs of CCSNe. We reiterate our earlier call for a paradigm shift from neutrino-driven explosion to a jet-driven explosion of CCSNe.

  16. REGULAR PATTERN MINING (WITH JITTER ON WEIGHTED-DIRECTED DYNAMIC GRAPHS

    Full Text Available Real world graphs are mostly dynamic in nature, exhibiting time-varying behaviour in structure of the graph, weight on the edges and direction of the edges. Mining regular patterns in the occurrence of edge parameters gives an insight into the consumer trends over time in ecommerce co-purchasing networks. But such patterns need not necessarily be precise as in the case when some product goes out of stock or a group of customers becomes unavailable for a short period of time. Ignoring them may lead to loss of useful information and thus taking jitter into account becomes vital. To the best of our knowledge, no work has been yet reported to extract regular patterns considering a jitter of length greater than unity. In this article, we propose a novel method to find quasi regular patterns on weight and direction sequences of such graphs. The method involves analysing the dynamic network considering the inconsistencies in the occurrence of edges. It utilizes the relation between the occurrence sequence and the corresponding weight and direction sequences to speed up this process. Further, these patterns are used to determine the most central nodes (such as the most profit yielding products. To accomplish this we introduce the concept of dynamic closeness centrality and dynamic betweenness centrality. Experiments on Enron e-mail dataset and a synthetic dynamic network show that the presented approach is efficient, so it can be used to find patterns in large scale networks consisting of many timestamps.

    Precise measurements of the arrival time jitter between the ionization laser, used to create the plasma, and the driver beam in the PWFA setup of the FLASHForward project are of high interest for the operation and optimization of the experiment. In this thesis, an electro-optic temporal decoding (EOTD) setup with near crossed polarizer detection scheme is presented, which can measure the timing-jitter to an accuracy of around 30 fs. This result was obtained during several measurements conducted at the coherent transition radiation beamline CTR141 at FLASH, using a 100 μm thick GaP crystal and coherent diffraction/transition radiation, generated from the FLASH1 electron bunches. Measurements were performed during long and short electron bunch operation at FLASH, showing that best results are obtained with CDR from long electron bunches. Utilizing CTR led to a higher EO signal and ''over-compensation'' of the SHG background level during the measurement, which resulted in a double-peak structure of the observed THz pulses. To resolve the single-cycle nature of these THz pulses, the SHG background had to be adjusted properly. Furthermore, EOTD measurements during a short bunch operation run at FLASH exhibited strong oscillations in the EO signal, which were suspected to come either from internal lattice resonances of the EO crystal or internal reflections, or excitation of water vapor in the humid air in the laboratory. The oscillations spoiled the observed EOTD trace leading to no sensible measurements of the arrival time jitter during this short bunch operation. To evaluate the capabilities of the setup for monitoring the timing jitter of short PWFA accelerated electron bunches or very short driver bunches at FLASHForward, further investigations on the observed oscillations in the EOTD traces have to be performed during short bunch operation at FLASH with different crystals and under vacuum conditions, to understand the oscillations of the EO signal better.

    The SLC thermionic gun and electron source produce a beam of up to 15 /times/ 10 10 /sub e//minus/ in a single S-band bunch. A 170 keV, 2 ns FWHM pulse out of the gun is compressed by means of two subharmonic buncher cavities followed by an S-band buncher and a standard SLAC accelerating section. Ceramic gaps in the beam pipe at the output of the gun allow a measure of the beam intensity and timing. A measurement at these gaps of the timing jitter, with a resolution of <10 ps, is described. 3 refs., 5 figs

    We look at migration flows from 8 Central and Eastern European Countries (CEECs) to 5 Nordic countries over the years 1985 - 2005 and we can exploit a natural experiment that arose from the fact that while Sweden opened its labour market from the day one of the 2004 EU enlargement, the other Nordic...... countries chose a transition period in relation to the "new" EU members. We employ a differences-in-differences estimator in our analysis. The results show that the estimated effect of the opening of Swedish labour market in 2004 on migration is insignificantly different from zero. Further, we...... are interested in the overall effect of the "EU entry" on migration. Therefore we look at migration flows from CEECs during the first round EU enlargement towards CEECs in 2004 and compare them with migration flows from Bulgaria and Romania. We again used a DD estimator in our analysis. The estimated effect...

    Full Text Available Satellite jitter is a common and complex phenomenon for the on-orbit high resolution satellites, which may affect the mapping accuracy and quality of imagery. A framework of jitter detection and compensation integrating data processing of multiple sensors is proposed in this paper. Jitter detection is performed based on multispectral imagery, three-line-array imagery, dense ground control and attitude measurement data, and jitter compensation is conducted both on image and on attitude with the sensor model. The platform jitter of ZY-3 satellite is processed and analyzed using the proposed technology, and the results demonstrate the feasibility and reliability of jitter detection and compensation. The variation law analysis of jitter indicates that the frequencies of jitter of ZY-3 satellite hold in the range between 0.6 and 0.7 Hz, while the amplitudes of jitter of ZY-3 satellite drop from 1 pixel in the early stage to below 0.4 pixels and tend to remain stable in the following stage.

    How to narrow the gap of security between theory and practice has been a notoriously urgent problem in quantum cryptography. Here, we analyze and provide experimental evidence of the clock jitter effect on the practical continuous-variable quantum key distribution (CV-QKD) system. The clock jitter is a random noise which exists permanently in the clock synchronization in the practical CV-QKD system, it may compromise the system security because of its impact on data sampling and parameters estimation. In particular, the practical security of CV-QKD with different clock jitter against collective attack is analyzed theoretically based on different repetition frequencies, the numerical simulations indicate that the clock jitter has more impact on a high-speed scenario. Furthermore, a simplified experiment is designed to investigate the influence of the clock jitter.

    In free electron laser (FEL) systems with ultraviolet (UV) laser driven injectors, a highly stable UV source generated through cascaded third harmonic generation (THG) from an infrared (IR) source is a key element in guaranteeing the acceptable current jitter at the undulator. In this letter, the negative slope of the THG efficiency for high intensity ultrashort IR pulses is revealed to be a passive stabilization mechanism for energy jitter reduction in UV. A reduction of 2.5 times the energy jitter in UV is demonstrated in the experiment and simulations show that the energy jitter in UV can be reduced by more than one order of magnitude if the energy jitter in IR is less than 3%, with proper design of the THG efficiency curve, fulfilling the challenging requirement for UV laser stability in a broad scope of applications such as the photoinjector of x-ray FELs.

    Fitzsimmons, W.A.; Rosocha, L.A.

    The properties of 10 to 30 kV four electrode field emission pre-ionized triggered spark gaps have been studied. A mid-plane off-axis trigger electrode is biased at +V 0 /2, and a field emission point is located adjacent to and biased at the grounded cathode potential. Simultaneous application of a -V 0 trigger rapid pulse to both the electrodes results in the rapid sequential closing of the anode-trigger and trigger-cathode gaps. The observed jitter is about 1.5 ns. Parallel operation of these gaps (up to 10 so far) connected to a common capacitive load has been studied. A simple theory that predicts the number of gaps that may be expected to operate in parallel is discussed

    Full Text Available Attitude jitter is a common phenomenon in the application of high resolution satellites, which may result in large errors of geo-positioning and mapping accuracy. Therefore, it is critical to detect and compensate attitude jitter to explore the full geometric potential of high resolution satellites. In this paper, a framework of jitter detection and compensation for high resolution satellites is proposed and some preliminary investigation is performed. Three methods for jitter detection are presented as follows. (1 The first one is based on multispectral images using parallax between two different bands in the image; (2 The second is based on stereo images using rational polynomial coefficients (RPCs; (3 The third is based on panchromatic images employing orthorectification processing. Based on the calculated parallax maps, the frequency and amplitude of the detected jitter are obtained. Subsequently, two approaches for jitter compensation are conducted. (1 The first one is to conduct the compensation on image, which uses the derived parallax observations for resampling; (2 The second is to conduct the compensation on attitude data, which treats the influence of jitter on attitude as correction of charge-coupled device (CCD viewing angles. Experiments with images from several satellites, such as ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiaometer, LRO (Lunar Reconnaissance Orbiter and ZY-3 (ZiYuan-3 demonstrate the promising performance and feasibility of the proposed framework.

  10. Jitter-Robust Orthogonal Hermite Pulses for Ultra-Wideband Impulse Radio Communications

    Directory of Open Access Journals (Sweden)

    Ryuji Kohno

    2005-03-01

    Full Text Available The design of a class of jitter-robust, Hermite polynomial-based, orthogonal pulses for ultra-wideband impulse radio (UWB-IR communications systems is presented. A unified and exact closed-form expression of the auto- and cross-correlation functions of Hermite pulses is provided. Under the assumption that jitter values are sufficiently smaller than pulse widths, this formula is used to decompose jitter-shifted pulses over an orthonormal basis of the Hermite space. For any given jitter probability density function (pdf, the decomposition yields an equivalent distribution of N-by-N matrices which simplifies the convolutional jitter channel model onto a multiplicative matrix model. The design of jitter-robust orthogonal pulses is then transformed into a generalized eigendecomposition problem whose solution is obtained with a Jacobi-like simultaneous diagonalization algorithm applied over a subset of samples of the channel matrix distribution. Examples of the waveforms obtained with the proposed design and their improved auto- and cross-correlation functions are given. Simulation results are presented, which demonstrate the superior performance of a pulse-shape modulated (PSM- UWB-IR system using the proposed pulses, over the same system using conventional orthogonal Hermite pulses, in jitter channels with additive white Gaussian noise (AWGN.

    2012-01-01

    Full Text Available This paper deals with the ITU-T E-model, which is used for non-intrusive MOS VoIP call quality estimation on IP networks. The pros of E-model are computational simplicity and usability on real-time traffic. The cons, as shown in our previous work, are the inability of E-model to reflect effects of network jitter present on real traffic flows and jitter-buffer behavior on end user devices. These effects are visible mostly on traffic over WAN, internet and radio networks and cause the E-model MOS call quality estimate to be noticeably too optimistic. In this paper, we propose a modification to E-model using previously proposed Pplef (effective packet loss using jitter and jitter-buffer model based on Pareto/D/1/K system. We subsequently perform optimization of newly added parameters reflecting jitter effects into E-model by using PESQ intrusive measurement method as a reference for selected audio codecs. Function fitting and parameter optimization is performed under varying delay, packet loss, jitter and different jitter-buffer sizes for both, correlated and uncorrelated long-tailed network traffic.

  12. EVIDENCE AGAINST AN ECOLOGICAL EXPLANATION OF THE JITTER ADVANTAGE FOR VECTION

    Full Text Available Visual-vestibular conflicts have been traditionally used to explain both perceptions of self-motion and experiences of motion sickness. However, sensory conflict theories have been challenged by findings that adding simulated viewpoint jitter to inducing displays enhances (rather than reduces or destroys visual illusions of self-motion experienced by stationary observers. One possible explanation of this jitter advantage for vection is that jittering optic flows are more ecological than smooth displays. Despite the intuitive appeal of this idea, it has proven difficult to test. Here we compared subjective experiences generated by jittering and smooth radial flows when observers were exposed to either visual-only or multisensory self-motion stimulations. The display jitter (if present was generated in real-time by updating the virtual computer-graphics camera position to match the observer’s tracked head motions when treadmill walking or walking in place, or was a playback of these head motions when standing still. As expected, the (more naturalistic treadmill walking and the (less naturalistic walking in place were found to generate very different physical head jitters. However, contrary to the ecological account of the phenomenon, playbacks of treadmill walking and walking in place display jitter both enhanced visually induced illusions of self-motion to a similar degree (compared to smooth displays.

    1990-01-01

    A zero-crossing detector (ZCD) was built and tested with a new circuit design which gives reduced time jitter compared to previous designs. With the new design, time jitter is reduced for the first time to a value which approaches that due to noise in the input amplifying stage. Additionally, with fiber-optic transmission of the output signal, crosstalk between units has been eliminated. The measured values are in good agreement with circuit noise calculations and approximately ten times lower than that for ZCD's presently installed in the JPL test facility. Crosstalk between adjacent units was reduced even more than the jitter.

    Full Text Available This paper presents a numerical analysis of latency and jitter for IEEE 802.11e wireless local area networks (WLANs in a saturation condition, by using a Markov model. We use this model to explicate how the enhanced distributed coordination function (EDCF differentiates classes of service and to characterize the probability distribution of the medium access control (MAC layer packet latency and jitter, on which the quality of the voice over Internet protocol (VoIP calls is dependent. From the proposed analytic model, we can estimate the available number of nodes determining the system performance, in order to satisfy user demands on the latency and jitter.

  15. Optimum FIR filter for sampled signals in presence of jitter

    Cattaneo, Paolo Walter

    1996-02-01

    The requirements of the integrated readout electronics for calorimetry at high luminosity hadron colliders pose new challenges both to hardware design and to the performance of signal processing algorithms. Both aspects have been treated in detail by the FERMI(RD16) collaboration [C. Alippi et al., Nucl. Instr. and Meth. A 344 (1994) 180], from which this work has been motivated. The estimation of the amplitude of sampled signals is usually performed with a digital FIR filter, or with a more sophisticated non linear digital filter using FIR filters as building blocks [S.J. Inkinen and J. Niittylahti, Trainable FIR-order statistic hybrid filters, to be published in IEEE Trans. Circuits and Systems; H. Alexanian et al., FERMI Collaboration, Optimized digital feature extraction in the FERMI microsystem Nucl. Instr. and Meth. A 357 (1995)]. In presence of significant signal phase jitter with respect to the clock, the phase dependence of the filter output can be a major source of error. This is especially true for measurements of large amplitudes for which the effect of electronic noise becomes negligible. This paper reports on the determination of digital FIR filters that optimize the signal over noise ratio due to known jitter distributions for different filter lengths. As the presence of electronic noise is neglected, the results are mainly relevant for measurements of large signals.

    The reaction of decamethylytterbocene [(η(5) -C5 Me5 )2 Yb(THF)2 ] with SO2 at low temperature gave two new compounds, namely, the Yb(III) dithionite/sulfinate complex [{(η(5) -C5 Me5 )2 Yb(μ3 ,1κ(2) O(1,3) ,2κ(3) O(2,2',4) -S2 O4 )}2 {(η(5) -C5 Me5 )Yb(μ,1κO,2κO'-C5 Me5 SO2 )}2 ] (1) and the Yb(III) dithionite complex [{(η(5) -C5 Me5 )2 Yb}2 (μ,1κ(2) O(1,3) ,2κ(2) O(2,4) -S2 O4 )] (2). After extraction of 1, the mixture was heated to give the dinuclear tetrasulfinate complex [{(η(5) -C5 Me5 )Yb}2 (μ,κO,κO'-C5 Me5 SO2 )4 ] (3 a). In contrast, from the reaction of [(η(5) -C5 Me5 )2 Eu(THF)2 ] with SO2 only the tetrasulfinate complex [{(η(5) -C5 Me5 )Eu}2 (μ,κO,κO'-C5 Me5 SO2 )4 ] (3 b) was isolated. Two major reaction pathways were observed: 1) reductive coupling of two SO2 molecules to form the dithionite anion S2 O4 (2-) ; and 2) nucleophilic attack of one metallocene C5 Me5 ligand on the sulfur atom of SO2 . The compounds presented are the first dithionite and sulfinate complexes of the f-elements. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The daily variation of the solar photocenter over some 11 yr is derived from the Mount Wilson data reprocessed by Ulrich et al. to closely match the surface distribution of solar irradiance. The standard deviations of astrometric jitter are 0.52 μAU and 0.39 μAU in the equatorial and the axial dimensions, respectively. The overall dispersion is strongly correlated with solar cycle, reaching 0.91 μAU at maximum activity in 2000. The largest short-term deviations from the running average (up to 2.6 μAU) occur when a group of large spots happen to lie on one side with respect to the center of the disk. The amplitude spectrum of the photocenter variations never exceeds 0.033 μAU for the range of periods 0.6-1.4 yr, corresponding to the orbital periods of planets in the habitable zone. Astrometric detection of Earth-like planets around stars as quiet as the Sun is not affected by star spot noise, but the prospects for more active stars may be limited to giant planets.

    This is the final report on our NASA grant, Problems in Microgravity Fluid Mechanics NAG3-2513: 12/14/2000 - 11/30/2003, extended through 11/30/2004. This grant was made to Stanford University and then transferred to the University of California at Santa Barbara when the PI relocated there in January 2001. Our main activity has been to conduct both experimental and theoretical studies of instabilities in fluids that are relevant to the microgravity environment, i.e. those that do not involve the action of buoyancy due to a steady gravitational field. Full details of the work accomplished under this grant are given below. Our work has focused on: (i) Theoretical and computational studies of the effect of g-jitter on instabilities of convective states where the convection is driven by forces other than buoyancy (ii) Experimental studies of instabilities during displacements of miscible fluid pairs in tubes, with a focus on the degree to which these mimic those found in immiscible fluids. (iii) Theoretical and experimental studies of the effect of time dependent electrohydrodynamic forces on chaotic advection in drops immersed in a second dielectric liquid. Our objectives are to acquire insight and understanding into microgravity fluid mechanics problems that bear on either fundamental issues or applications in fluid physics. We are interested in the response of fluids to either a fluctuating acceleration environment or to forces other than gravity that cause fluid mixing and convection. We have been active in several general areas.

    We report on the measurement of the laser–rf phase jitter in a photocathode rf gun with femtosecond precision. In this experiment four laser pulses with equal separation are used to produce electron bunch trains; then the laser–rf phase jitter is obtained by measuring the variations of the electron bunch spacing with an rf deflector. Furthermore, we show that when the gun and the deflector are powered by the same rf source, it is possible to obtain the laser–rf phase jitter in the gun through measurement of the beam–rf phase jitter in the deflector. Based on these measurements, we propose an effective time-stamping method that may be applied in MeV ultrafast electron diffraction facilities to enhance the temporal resolution.

    We report on the measurement of the laser–rf phase jitter in a photocathode rf gun with femtosecond precision. In this experiment four laser pulses with equal separation are used to produce electron bunch trains; then the laser–rf phase jitter is obtained by measuring the variations of the electron bunch spacing with an rf deflector. Furthermore, we show that when the gun and the deflector are powered by the same rf source, it is possible to obtain the laser–rf phase jitter in the gun through measurement of the beam–rf phase jitter in the deflector. Based on these measurements, we propose an effective time-stamping method that may be applied in MeV ultrafast electron diffraction facilities to enhance the temporal resolution.

  3. An adaptive feedback controller for transverse angle and position jitter correction in linear particle beam accelerators

    It is desired to design a position and angle jitter control system for pulsed linear accelerators that will increase the accuracy of correction over that achieved by currently used standard feedback jitter control systems. Interpulse or pulse-to-pulse correction is performed using the average value of each macropulse. The configuration of such a system resembles that of a standard feedback correction system with the addition of an adaptive controller that dynamically adjusts the gain-phase contour of the feedback electronics. The adaptive controller makes changes to the analog feedback system between macropulses. A simulation of such a system using real measured jitter data from the Stanford Linear Collider was shown to decrease the average rms jitter by over two and a half times. The system also increased and stabilized the correction at high frequencies; a typical problem with standard feedback systems

    EU energy policies have changed focus in the last few years with a view to substantially reducing energy import dependency and greenhouse gas emissions. The EU Commission has played a leading role in defining the new orientations. The implementation of the EU policy objectives approved by the Council of March 2007 will require a substantial expansion of energy investments. However, the degree of uncertainty affecting investment decisions remains high, notably in relation to the pricing of CO2...

    This paper explores the relationship between contract theory and European contract law. In particular, it confronts the leading contract law theories with the main characteristics of EU contract law. The conclusion is that the two do not match well. In particular, monist normative contract theories are largely irreconcilable with the contract law of the EU. The paper further addresses the main implications of this mismatch, both for contract theory and for EU contract law. It suggests that in...

    Full Text Available VAT is one of the newest tools of the global economy and is widely adopted in most of the countries. For EU Member States is required not only the existence of VAT, but also that its main characteristics to be uniformly implemented. This should facilitate intra-Community transactions, but in practice does not as there are many local variations which can lead to costly errors and penalties. The objective of this paper is to collate data about the main characteristics of VAT in EU Member States and to highlight the key differences between them. This survey shows that there continue to be opportunities and risks for businesses trading cross border, as a result of differences in application of Community legislation on VAT. This led to the necessity of VAT reform. On this basis, the Commission adopted on the end of the last year a Communication on the future of VAT. This sets out the fundamental characteristics that must underlie the new VAT regime, and priority actions needed to create a simpler, more efficient and more robust VAT system in the EU.

    For nearly 20 years, the California Planet Search (CPS) has simultaneously monitored precise radial velocities and chromospheric activity levels of stars from Keck observatory to search for exoplanets. This sample provides a useful set of stars to better determine the dependence of RV jitter on flicker (which traces surface gravity) first shown in Bastien et al. (2014). We expand upon this initial work by examining a much larger sample of stars covering a much wider range of stellar parameters (effective temperature, surface gravity, and activity, among others). For more than 600 stars, there are enough RV measurements to distinguish this astrophysical jitter from accelerations due to orbital companions. To properly isolate RV jitter from these effects, we must first remove the RV signal due to these companions, including several previously unannounced giant planets around subgiant stars. We highlight some new results from our analysis of the CPS data. A more thorough understanding of the various sources of RV jitter and the underlying stellar phenomena that drive these intrinsic RV variations will enable more precise jitter estimates for RV follow-up targets such as those from K2 or the upcoming TESS mission.

    An experimental plasma accelerator for a variety of applications under development at the NASA Marshall Space Flight Center is described. The accelerator is a pulsed plasma thruster and has been tested experimentally and plasma jet velocities of approximately 50 kilometers per second have been obtained. The plasma jet structure has been photographed with 10 ns exposure times to reveal a stable and repeatable plasma structure. Data for velocity profile information has been obtained using light pipes embedded in the gun walls to record the plasma transit at various barrel locations. Preliminary spatially resolved spectral data and magnetic field probe data are also presented. A high speed triggering system has been developed and tested as a means of reducing the gun "jitter". This jitter has been characterized and future work for second generation "ultra-low jitter" gun development is identified.

  12. Real-time operating system timing jitter and its impact on motor control

    Proctor, Frederick M.; Shackleford, William P.

    2001-12-01

    General-purpose microprocessors are increasingly being used for control applications due to their widespread availability and software support for non-control functions like networking and operator interfaces. Two classes of real-time operating systems (RTOS) exist for these systems. The traditional RTOS serves as the sole operating system, and provides all OS services. Examples include ETS, LynxOS, QNX, Windows CE and VxWorks. RTOS extensions add real-time scheduling capabilities to non-real-time OSes, and provide minimal services needed for the time-critical portions of an application. Examples include RTAI and RTL for Linux, and HyperKernel, OnTime and RTX for Windows NT. Timing jitter is an issue in these systems, due to hardware effects such as bus locking, caches and pipelines, and software effects from mutual exclusion resource locks, non-preemtible critical sections, disabled interrupts, and multiple code paths in the scheduler. Jitter is typically on the order of a microsecond to a few tens of microseconds for hard real-time operating systems, and ranges from milliseconds to seconds in the worst case for soft real-time operating systems. The question of its significance on the performance of a controller arises. Naturally, the smaller the scheduling period required for a control task, the more significant is the impact of timing jitter. Aside from this intuitive relationship is the greater significance of timing on open-loop control, such as for stepper motors, than for closed-loop control, such as for servo motors. Techniques for measuring timing jitter are discussed, and comparisons between various platforms are presented. Techniques to reduce jitter or mitigate its effects are presented. The impact of jitter on stepper motor control is analyzed.

  13. Leadership Revised: How Did the Ukraine Crisis and the Annexation of Crimea Affirm Germany’s Leading Role in EU Foreign Policy?

    2016-12-01

    Full Text Available The recent string of existential crises in Europe - the Euro crisis, Russia’s aggression in Ukraine and the refugee crisis of 2015 - have resulted in new dynamics within the European Union. In Brussels, Germany has emerged as the hardly contested nexus of decision making. It was in particular through the Ukraine crisis and the annexation of Crimea by Russia in 2014 that Germany found itself assuming a leadership role also in the EU’s foreign policy, a role it has shunned in the past. However, for Berlin this new role is far from obvious - it is only gradually that Germany grew comfortable with its enhanced role, which is due more to external circumstances than by its own design. Conscious of its own image abroad and, due to the still prevalent feeling of historical guilt, the fear of being perceived as a dominating power has so far prevented Germany from occupying the forefront of the stage, preferring to pulling strings from behind and presenting itself as the EU’s “Chief Facilitation Officer”. This article analyses how Germany, in particular through the Ukraine crisis starting in 2014, affirmed itself - albeit reluctantly - as a nexus of decision making in the EU’s Common Foreign and Security Policy (CFSP and became the de facto leading nation for defining the EU’s response towards Russia. The article points out the internal and external consequences of this new role and, in particular, its impact on the Baltic States.

    A programmable delay circuit design which has characteristics of high-precision, low-jitter, wide-programmable-range and low power is introduced. The delay circuitry uses the scheme which has two parts: the coarse delay and the fine delay that could be controlled separately. Using different coarse delay chip can reach different maximum programmable range. And the fine delay programmable chip has the minimum step which is down to 10 ps. The whole circuitry jitter will be less than 100 ps. The design has been successfully applied in Quantum Key Distribution experiment. (authors)

  16. Removal of jitter noise in 3D shape recovery from image focus by using Kalman filter.

    Jang, Hoon-Seok; Muhammad, Mannan Saeed; Choi, Tae-Sun

    2018-02-01

    In regard to Shape from Focus, one critical factor impacting system application is mechanical vibration of the translational stage causing jitter noise along the optical axis. This noise is not detectable by simply observing the image. However, when focus measures are applied, inaccuracies in the depth occur. In this article, jitter noise and focus curves are modeled by Gaussian distribution and quadratic function, respectively. Then Kalman filter is designed and applied to eliminate this noise in the focus curves, as a post-processing step after the focus measure application. Experiments are implemented with simulated objects and real objects to show usefulness of proposed algorithm. © 2017 Wiley Periodicals, Inc.

  17. A Low-Jitter Wireless Transmission Based on Buffer Management in Coding-Aware Routing

    Directory of Open Access Journals (Sweden)

    Cunbo Lu

    2015-08-01

    Full Text Available It is significant to reduce packet jitter for real-time applications in a wireless network. Existing coding-aware routing algorithms use the opportunistic network coding (ONC scheme in a packet coding algorithm. The ONC scheme never delays packets to wait for the arrival of a future coding opportunity. The loss of some potential coding opportunities may degrade the contribution of network coding to jitter performance. In addition, most of the existing coding-aware routing algorithms assume that all flows participating in the network have equal rate. This is unrealistic, since multi-rate environments often appear. To overcome the above problem and expand coding-aware routing to multi-rate scenarios, from the view of data transmission, we present a low-jitter wireless transmission algorithm based on buffer management (BLJCAR, which decides packets in coding node according to the queue-length based threshold policy instead of the regular ONC policy as used in existing coding-aware routing algorithms. BLJCAR is a unified framework to merge the single rate case and multiple rate case. Simulations results show that the BLJCAR algorithm embedded in coding-aware routing outperforms the traditional ONC policy in terms of jitter, packet delivery delay, packet loss ratio and network throughput in network congestion in any traffic rates.

    This paper shows that, for a given power budget, a practical phase-locked loop (PLL)-based clock multiplier generates less jitter than a delay-locked loop (DLL) equivalent. This is due to the fact that the delay cells in a PLL ring-oscillator can consume more power per cell than their counterparts

  2. Photodetection-induced relative timing jitter in synchronized time-lens source for coherent Raman scattering microscopy

    Directory of Open Access Journals (Sweden)

    Jiaqi Wang

    2017-09-01

    Full Text Available Synchronized time-lens source is a novel method to generate synchronized optical pulses to mode-locked lasers, and has found widespread applications in coherent Raman scattering microscopy. Relative timing jitter between the mode-locked laser and the synchronized time-lens source is a key parameter for evaluating the synchronization performance of such synchronized laser systems. However, the origins of the relative timing jitter in such systems are not fully determined, which in turn prevents the experimental efforts to optimize the synchronization performance. Here, we demonstrate, through theoretical modeling and numerical simulation, that the photodetection could be one physical origin of the relative timing jitter. Comparison with relative timing jitter due to the intrinsic timing jitter of the mode-locked laser is also demonstrated, revealing different qualitative and quantitative behaviors. Based on the nature of this photodetection-induced timing jitter, we further propose several strategies to reduce the relative timing jitter. Our theoretical results will provide guidelines for optimizing synchronization performance in experiments.

  4. Microphone triggering circuit for elimination of mechanically induced frequency-jitter in diode laser spectrometers: implications for quantitative analysis.

    Science.gov (United States)

    Sams, R L; Fried, A

    1987-09-01

    An electronic timing circuit using a microphone triggering device has been developed for elimination of mechanically induced frequency-jitter in diode laser spectrometers employing closed-cycle refrigerators. Mechanical compressor piston shocks are detected by the microphone and actuate an electronic circuit which ultimately interrupts data acquisition until the mechanical vibrations are completely quenched. In this way, laser sweeps contaminated by compressor frequency-jitter are not co-averaged. Employing this circuit, measured linewidths were in better agreement with that calculated. The importance of eliminating this mechanically induced frequency-jitter when carrying out quantitative diode laser measurements is further discussed.

  5. Rethinking EU Citizenship: Towards the Postmodern Ethics of Citizenship

    Directory of Open Access Journals (Sweden)

    Sanja IVIC

    2009-11-01

    Full Text Available The concept of EU citizenship reflects EU politics of (fixed identity, which guarantees rights only to the homogenous groups (and individuals as representatives of these groups. Hence, it leaves room for marginalizing, othering, excluding and other forms of discrimination, by creating binary oppositions: we/they, citizen/alien, EU/non-EU and so forth. EU citizenship is based on the modernist ethics of priority of right over the good. It is created to promote European idea, so it has only instrumental value. On the other hand, the politics of affinity leads to the substantive EU citizenship founded on multiple identities. The politics of affinity requires a new ethics which will lead to transformation of the main concepts of EU legal discourse.

    A design of optical axis closed-loop control system for multi beam lasers coherent combining based on FPGA was introduced. The system uses piezoelectric ceramics Fast Steering Mirrors (FSM) as actuator, the Fairfield spot detection of multi beam lasers by the high speed CMOS camera for optical detecting, a control system based on FPGA for real-time optical axis jitter suppression. The algorithm for optical axis centroid detecting and PID of anti-Integral saturation were realized by FPGA. Optimize the structure of logic circuit by reuse resource and pipeline, as a result of reducing logic resource but reduced the delay time, and the closed-loop bandwidth increases to 100Hz. The jitter of laser less than 40Hz was reduced 40dB. The cost of the system is low but it works stably.

    This paper describes a ring oscillator based low jitter charge pump PLL with supply regulation and digital calibration. In order to combat power supply noise, a low drop output voltage regulator is implemented. The VCO gain is tunable by using the 4 bit control self-calibration technique. So that the optimal VCO gain is automatically selected and the process/temperature variation is compensated. Fabricated in the 0.13 μm CMOS process, the PLL achieves a frequency range of 100–400 MHz and occupies a 190 × 200 μm 2 area. The measured RMS jitter is 5.36 ps at a 400 MHz operating frequency.

    During the 2005 Los Alamos Neutron Science Center (LANSCE) beam runs, beam current and centroid-jitter data were observed, acquired, analyzed, and documented for both the LANSCE H+ and H- beams. These data were acquired using three beam position monitors (BPMs) from the 100-MeV Isotope Production Facility (IPF) beam line and three BPMs from the Switchyard transport line at the end of the LANSCE 800-MeV linac. The two types of data acquired, intermacropulse and intramacropulse, were analyzed for statistical and frequency characteristics as well as various other correlations including comparing their phase-space like characteristics in a coordinate system of transverse angle versus transverse position. This paper will briefly describe the measurements required to acquire these data, the initial analysis of these jitter data, and some interesting dilemmas these data presented.

    With constant incentives for healthcare payers to contain their pharmaceutical budgets, forecasting has become critically important. Some countries have, for instance, developed pharmaceutical horizon scanning units. The objective of this project was to build a model to assess the net effect of the entrance of new patented medicinal products versus medicinal products going off-patent, with a defined forecast horizon, on selected European Union (EU) Member States' pharmaceutical budgets. This model took into account population ageing, as well as current and future country-specific pricing, reimbursement, and market access policies (the project was performed for the European Commission; see http://ec.europa.eu/health/healthcare/key_documents/index_en.htm). In order to have a representative heterogeneity of EU Member States, the following countries were selected for the analysis: France, Germany, Greece, Hungary, Poland, Portugal, and the United Kingdom. A forecasting period of 5 years (2012-2016) was chosen to assess the net pharmaceutical budget impact. A model for generics and biosimilars was developed for each country. The model estimated a separate and combined effect of the direct and indirect impacts of the patent cliff. A second model, estimating the sales development and the risk of development failure, was developed for new drugs. New drugs were reviewed individually to assess their clinical potential and translate it into commercial potential. The forecast was carried out according to three perspectives (healthcare public payer, society, and manufacturer), and several types of distribution chains (retail, hospital, and combined retail and hospital). Probabilistic and deterministic sensitivity analyses were carried out. According to the model, all countries experienced drug budget reductions except Poland (+€41 million). Savings were expected to be the highest in the United Kingdom (-€9,367 million), France (-€5,589 million), and, far behind them

    The high-power switch plays an important part in a pulse power system. With the trend of pulse power technology toward modularization, miniaturization, and accuracy control, higher requirements on electrical trigger and jitter of the switch have been put forward. A high-power low-jitter corona-stabilized triggered switch (CSTS) is designed in this paper. This kind of CSTS is based on corona stabilized mechanism, and it can be used as a main switch of an intense electron-beam accelerator (IEBA). Its main feature was the use of an annular trigger electrode instead of a traditional needle-like trigger electrode, taking main and side trigger rings to fix the discharging channels and using SF6/N2 gas mixture as its operation gas. In this paper, the strength of the local field enhancement was changed by a trigger electrode protrusion length Dp. The differences of self-breakdown voltage and its stability, delay time jitter, trigger requirements, and operation range of the switch were compared. Then the effect of different SF6/N2 mixture ratio on switch performance was explored. The experimental results show that when the SF6 is 15% with the pressure of 0.2 MPa, the hold-off voltage of the switch is 551 kV, the operating range is 46.4%-93.5% of the self-breakdown voltage, the jitter is 0.57 ns, and the minimum trigger voltage requirement is 55.8% of the peak. At present, the CSTS has been successfully applied to an IEBA for long time operation.

  13. High time resolution beam-based measurement of the rf-to-laser jitter in a photocathode rf gun

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available Characterizing the rf-to-laser jitter in the photocathode rf gun and its possible origins is important for improving the synchronization and beam quality of the linac based on the photocathode rf gun. A new method based on the rf compression effect in the photocathode rf gun is proposed to measure the rf-to-laser jitter in the gun. By taking advantage of the correlation between the rf compression and the laser injection phase, the error caused by the jitter of the accelerating field in the gun is minimized and thus 10 fs time resolution is expected. Experimental demonstration at the Tsinghua Thomson scattering x-ray source with a time resolution better than 35 fs is reported in this paper. The experimental results are successfully used to obtain information on the possible cause of the jitter and the accompanying drifts.

  14. Influence of incident light wavelength on time jitter of fast photomultipliers

    Moszynski, M.; Vacher, J.

    1977-01-01

    The study of the single photoelectron time resolution as a function of the wavelength of the incident light was performed for a 56 CVP photomultiplier having an S-1 photocathode. The light flash from the XP22 light emitting diode generator was passed through passband filters and illuminated the 5 mm diameter central part of the photocathode. A significant increase of the time resolution above 30% was observed when the wavelength of the incident light was changed from 790 nm to 580 nm. This gives experimental evidence that the time jitter resulting from the spread of the initial velocity of photoelectrons is proportional to the square root of the maximal initial energy of photoelectrons. Based on this conclusion the measured time jitter of C31024, RCA8850 and XP2020 photomultipliers with the use of the XP22 light emitting diode at 560 nm light wavelength was recalculated to estimate the time jitter at 400 nm near the maximum of the photocathode sensitivity. It shows an almost twice larger time spread at 400 nm for the C31024 and RCA8850 with a high gain first dynode and an about 1.5 times larger time spread for the XP2020 photomultiplier, than those measured at 560 nm.

    Numerous communication techniques and optical devices successfully applied in space optical communication system indicates a good portability of it. With this good portability, typical coherent demodulation technique of Costas loop can be easily adopted in space optical communication system. As one of the components of pointing error, the effect of jitter plays an important role in the communication quality of such system. Here, we obtain the probability density functions (PDF) of different jitter degrees and explain their essential effect on the bit error rate (BER) space optical communication system. Also, under the effect of jitter, we research the bit error rate of space coherent optical communication system using Costas loop with different system parameters of transmission power, divergence angle, receiving diameter, avalanche photodiode (APD) gain, and phase deviation caused by Costas loop. Through a numerical simulation of this kind of communication system, we demonstrate the relationship between the BER and these system parameters, and some corresponding methods of system optimization are presented to enhance the communication quality.

    The sampling jitter noise is one non-negligible noise source of the digital phasemeter used for space gravitational wave detection missions. This note provides a new method for directly reducing the sampling jitter noise of the digital phasemeter, by adding a dedicated signal of which the frequency, amplitude, and initial phase should be pre-set. In contrast to the phase correction using the pilot-tone in the work of Burnett, Gerberding et al., Liang et al., Ales et al., Gerberding et al., and Ware et al. [M.Sc. thesis, Luleå University of Technology, 2010; Classical Quantum Gravity 30, 235029 (2013); Rev. Sci. Instrum. 86, 016106 (2015); Rev. Sci. Instrum. 86, 084502 (2015); Rev. Sci. Instrum. 86, 074501 (2015); and Proceedings of the Earth Science Technology Conference (NASA, USA, 2006)], the new method is intrinsically additive noise suppression. The experiment results validate that the new method directly reduces the sampling jitter noise without data post-processing and provides the same phase measurement noise level (10-6 rad/Hz1/2 at 0.1 Hz) as the pilot-tone correction.

    Low jitter, high reliability impulse generator development has recently become of ever increasing importance for developing nuclear physics and weapons applications. The research and development of very low jitter (< 30 ps), multikilovolt generators for high reliability, minimum maintenance trigger applications utilizing a new class of high-pressure tetrode thyratrons now commercially available are described. The overall system design philosophy is described followed by a detailed analysis of the subsystem component elements. A multi-variable experimental analysis of this new tetrode thyratron was undertaken, in a low-inductance configuration, as a function of externally available parameters. For specific thyratron trigger conditions, rise times of 18 ns into 6.0-Ω loads were achieved at jitters as low as 24 ps. Using this database, an integrated trigger generator system with solid-state front-end is described in some detail. The generator was developed to serve as the Master Trigger Generator for a large neutrino detector installation at the Los Alamos Meson Physics Facility

    A novel structure of a phase-locked loop (PLL) characterized by a short locking time and low jitter is presented, which is realized by generating a linear slope charge pump current dependent on monitoring the output of the phase frequency detector (PFD) to implement adaptive bandwidth control. This improved PLL is created by utilizing a fast start-up circuit and a slope current control on a conventional charge pump PLL. First, the fast start-up circuit is enabled to achieve fast pre-charging to the loop filter. Then, when the output pulse of the PFD is larger than a minimum value, the charge pump current is increased linearly by the slope current control to ensure a shorter locking time and a lower jitter. Additionally, temperature variation is attenuated with the temperature compensation in the charge pump current design. The proposed PLL has been fabricated in a kind of DSP chip based on a 0.35 μm CMOS process. Comparing the characteristics with the classical PLL, the proposed PLL shows that it can reduce the locking time by 60% with a low peak-to-peak jitter of 0.3% at a wide operation temperature range.

  19. Dynamics of the Drosophila circadian clock: theoretical anti-jitter network and controlled chaos.

    Directory of Open Access Journals (Sweden)

    Hassan M Fathallah-Shaykh

    Full Text Available BACKGROUND: Electronic clocks exhibit undesirable jitter or time variations in periodic signals. The circadian clocks of humans, some animals, and plants consist of oscillating molecular networks with peak-to-peak time of approximately 24 hours. Clockwork orange (CWO is a transcriptional repressor of Drosophila direct target genes. METHODOLOGY/PRINCIPAL FINDINGS: Theory and data from a model of the Drosophila circadian clock support the idea that CWO controls anti-jitter negative circuits that stabilize peak-to-peak time in light-dark cycles (LD. The orbit is confined to chaotic attractors in both LD and dark cycles and is almost periodic in LD; furthermore, CWO diminishes the Euclidean dimension of the chaotic attractor in LD. Light resets the clock each day by restricting each molecular peak to the proximity of a prescribed time. CONCLUSIONS/SIGNIFICANCE: The theoretical results suggest that chaos plays a central role in the dynamics of the Drosophila circadian clock and that a single molecule, CWO, may sense jitter and repress it by its negative loops.

  20. Low-sensitivity H ∞ filter design for linear delta operator systems with sampling time jitter

    Science.gov (United States)

    Guo, Xiang-Gui; Yang, Guang-Hong

    2012-04-01

    This article is concerned with the problem of designing H ∞ filters for a class of linear discrete-time systems with low-sensitivity to sampling time jitter via delta operator approach. Delta-domain model is used to avoid the inherent numerical ill-condition resulting from the use of the standard shift-domain model at high sampling rates. Based on projection lemma in combination with the descriptor system approach often used to solve problems related to delay, a novel bounded real lemma with three slack variables for delta operator systems is presented. A sensitivity approach based on this novel lemma is proposed to mitigate the effects of sampling time jitter on system performance. Then, the problem of designing a low-sensitivity filter can be reduced to a convex optimisation problem. An important consideration in the design of correlation filters is the optimal trade-off between the standard H ∞ criterion and the sensitivity of the transfer function with respect to sampling time jitter. Finally, a numerical example demonstrating the validity of the proposed design method is given.

  4. Influence of P300 latency jitter on event related potential-based brain-computer interface performance

    Aricò, P.; Aloise, F.; Schettini, F.; Salinari, S.; Mattia, D.; Cincotti, F.

    2014-06-01

    Objective. Several ERP-based brain-computer interfaces (BCIs) that can be controlled even without eye movements (covert attention) have been recently proposed. However, when compared to similar systems based on overt attention, they displayed significantly lower accuracy. In the current interpretation, this is ascribed to the absence of the contribution of short-latency visual evoked potentials (VEPs) in the tasks performed in the covert attention modality. This study aims to investigate if this decrement (i) is fully explained by the lack of VEP contribution to the classification accuracy; (ii) correlates with lower temporal stability of the single-trial P300 potentials elicited in the covert attention modality. Approach. We evaluated the latency jitter of P300 evoked potentials in three BCI interfaces exploiting either overt or covert attention modalities in 20 healthy subjects. The effect of attention modality on the P300 jitter, and the relative contribution of VEPs and P300 jitter to the classification accuracy have been analyzed. Main results. The P300 jitter is higher when the BCI is controlled in covert attention. Classification accuracy negatively correlates with jitter. Even disregarding short-latency VEPs, overt-attention BCI yields better accuracy than covert. When the latency jitter is compensated offline, the difference between accuracies is not significant. Significance. The lower temporal stability of the P300 evoked potential generated during the tasks performed in covert attention modality should be regarded as the main contributing explanation of lower accuracy of covert-attention ERP-based BCIs.

    Faced with the mounting evidence of the harmful effects of climate change, the European Union is convinced that the world must take urgent action to tackle the problem. That is why the EU has been at the forefront of international efforts to deal with climate change for well over a decade. The EU is convinced that the status quo is simply not an option. Without urgent, concerted action, the problem will continue to get worse with potentially disastrous consequences. That is why the European Union has consistently taken the lead in international moves to tackle climate change and why it will continue to develop this strategy for as long as it takes to guarantee a world for ourselves and our children where everyone can grow, breathe and live in safety

    2009-08-01

    Full Text Available Switching can be considered to be the essence of pulsed power. Time accurate switch/trigger systems with low inductance are useful in many applications. This article describes a unique switch geometry coupled with a low-inductance capacitive energy store. The system provides a fast-rising high voltage pulse into a low impedance load. It can be challenging to generate high voltage (more than 50 kilovolts into impedances less than 10  Ω, from a low voltage control signal with a fast rise time and high temporal accuracy. The required power amplification is large, and is usually accomplished with multiple stages. The multiple stages can adversely affect the temporal accuracy and the reliability of the system. In the present application, a highly reliable and low jitter trigger generator was required for the Z pulsed-power facility [M. E. Savage, L. F. Bennett, D. E. Bliss, W. T. Clark, R. S. Coats,J. M. Elizondo, K. R. LeChien, H. C. Harjes, J. M. Lehr, J. E. Maenchen, D. H. McDaniel, M. F. Pasik, T. D. Pointon, A. C. Owen, D. B. Seidel, D. L. Smith, B. S. Stoltzfus, K. W. Struve, W. A. Stygar, L. K. Warne, and J. R. Woodworth, 2007 IEEE Pulsed Power Conference, Albuquerque, NM (IEEE, Piscataway, NJ, 2007, p. 979]. The large investment in each Z experiment demands low prefire probability and low jitter simultaneously. The system described here is based on a 100 kV DC-charged high-pressure spark gap, triggered with an ultraviolet laser. The system uses a single optical path for simultaneously triggering two parallel switches, allowing lower inductance and electrode erosion with a simple optical system. Performance of the system includes 6 ns output rise time into 5.6  Ω, 550 ps one-sigma jitter measured from the 5 V trigger to the high voltage output, and misfire probability less than 10^{-4}. The design of the system and some key measurements will be shown in the paper. We will discuss the

    The relative bit density variation graphs of 207 specimen credit cards processed by 12 encoding machines were examined first visually, and then classified by means of hierarchical cluster analysis. Twenty-nine credit cards being treated as 'questioned' samples were tested by way of cluster analysis against 'controls' derived from known encoders. It was found that hierarchical cluster analysis provided a high accuracy of identification with all 29 'questioned' samples classified correctly. On the other hand, although visual comparison of jitter graphs was less discriminating, it was nevertheless capable of giving a reasonably accurate result.

    We found by using Monte Carlo simulations that the timing jitter in a dispersion-managed soliton system decreases as the strength of the dispersion management and hence the ratio of the pulse energy to the pulse bandwidth increases. The results are in qualitative but not quantitative agreement with earlier predictions that the decrease is inversely proportional to the square root of the pulse energy. Using an improved semi-analytical theory, we obtained quantitative agreement with the simulations. copyright 1998 Optical Society of America

The switch operates with less than 2 ns jitter, recovers its dielectric strength within 2 to 5 ms and has not shown degraded performance in sequential test runs totaling over a million shots. Its estimated life with copper electrodes is > 10 7 shots. All preliminary tests indicate that the switch is suitable for continuous running multi-kilojoule systems operating to at least 20 pps

    We present a double unbalanced Michelson interferometer producing up to four output pulses from a single input pulse. The interferometer is stabilized with the Hänsch-Couillaud method using an auxiliary low power continuous wave laser injected into the interferometer, allowing the stabilization of the temporal jitter of the output pulses to 0.02 fs. Such stabilized pulse trains would be suitable for driving multi-pulse laser wakefield accelerators, and the technique could be extended to include amplification in the arms of the interferometer.

    Graphical abstract: - Highlights: • Silver nanoparticles are precipitated from the borate glasses during the melting process without any further heat treatment. • The reduction of Eu 3+ ions to Eu 2+ ions is presented in this material. • The intensity of Ag + luminescence. • The introduction of Eu ions accelerated the reaction between Eu 2+ ions and silver ions inducing the silver clusters formation. - Abstract: Ag + doped sodium borate glasses with different Eu ions concentration were prepared by the melt-quenching method. The absorption at about 410 nm which was caused by the surface plasmon resonance (SPR) of Ag nanoparticles (NPs) is promoted with increasing of Eu ions concentration. Meanwhile, the luminescent spectra showed that the emission intensity of Ag + decreased while that of the Ag aggregates increased simultaneously. The results indicated that the Ag ions intend to form the high-polymeric state such as Ag aggregates and nanoparticles with increasing of europium ions. Owing to the self-reduction of Eu 3+ to Eu 2+ in our glass system, it revealed that Ag + has been reduced by the neighboring Eu 2+ which leads to the formation of Ag aggregates and the precipitation of Ag NPs in the matrix. In addition, energy transfer (ET) process from Ag + /Ag aggregates to the Eu 3+ was investigated for the enhancement of Eu 3+ luminescence

Conventional thermal power plants generated 1340,1 billion kWh, which corresponds to a 53.0% share in the total generation and an increase by 2.7% over the level in the previous year. Generation in nuclear power plants increased by 2.7% to 855.5 billion kWh, which corresponds to a 33,8% share in EU-wide generation. Hydroelectric plants and other plants supplied 15.2% less electricity. Eurostat statistics do not differentiate these data any further. The volume of 332.2 kWh is tantamount to a 13.1% share. In the new EU member countries and the candidate countries, electricity generation showed a moderate increase by 0.4% and 2.1%, respectively.

    Saqib Hakak

    2015-01-01

    Full Text Available A mobile ad-hoc network (MANET is a self-configuring infrastructure-less network of mobile devices connected by wireless links where each node or mobile device is independent to move in any desired direction and thus the links keep moving from one node to another. In such a network, the mobile nodes are equipped with CSMA/CA (carrier sense multiple access with collision avoidance transceivers and communicate with each other via radio. In MANETs, routing is considered one of the most difficult and challenging tasks. Because of this, most studies on MANETs have focused on comparing protocols under varying network conditions. But to the best of our knowledge no one has studied the effect of other factors on network performance indicators like throughput, jitter and so on, revealing how much influence a particular factor or group of factors has on each network performance indicator. Thus, in this study the effects of three key factors, i.e. routing protocol, packet size and DSSS rate, were evaluated on key network performance metrics, i.e. average delay and average jitter, as these parameters are crucial for network performance and directly affect the buffering requirements for all video devices and downstream networks.

    A review on CMOS delay lines with a focus on the most frequently used techniques for high-resolution delay step is presented. The primary types, specifications, delay circuits, and operating principles are presented. The delay circuits reported in this paper are used for delaying digital inputs and clock signals. The most common analog and digitally-controlled delay elements topologies are presented, focusing on the main delay-tuning strategies. IC variables, namely, process, supply voltage, temperature, and noise sources that affect delay resolution through timing jitter are discussed. The design specifications of these delay elements are also discussed and compared for the common delay line circuits. As a result, the main findings of this paper are highlighting and discussing the followings: the most efficient high-resolution delay line techniques, the trade-off challenge found between CMOS delay lines designed using either analog or digitally-controlled delay elements, the trade-off challenge between delay resolution and delay range and the proposed solutions for this challenge, and how CMOS technology scaling can affect the performance of CMOS delay lines. Moreover, the current trends and efforts used in order to generate output delayed signal with low jitter in the sub-picosecond range are presented.

    In order to guarantee the quantity of data traffic delivered in the network, congestion control strategy is adopted. According to the study of many active queue management (AQM) algorithms, this paper proposes a novel active queue management algorithm named JFED. JFED can stabilize queue length at a desirable level by adjusting output traffic rate and adopting a reasonable calculation of packet drop probability based on buffer queue length and traffic jitter; and it support burst packet traffic through the packet delay jitter, so that it can traffic flow medium data. JFED impose effective punishment upon non-responsible flow with a full stateless method. To verify the performance of JFED, it is implemented in NS2 and is compared with RED and CHOKe with respect to different performance metrics. Simulation results show that the proposed JFED algorithm outperforms RED and CHOKe in stabilizing instantaneous queue length and in fairness. It is also shown that JFED enables the link capacity to be fully utilized by stabilizing the queue length at a desirable level, while not incurring excessive packet loss ratio.

    Linear and circular polarizations of gamma-ray bursts (GRBs) have been detected recently. We adopt a simplified model to investigate GRB polarization characteristics in this paper. A compressed two-dimensional turbulent slab containing stochastic magnetic fields is considered, and jitter radiation can produce the linear polarization under this special magnetic field topology. Turbulent Faraday rotation measure (RM) of this slab makes strong wavelength-dependent depolarization. The jitter photons can also scatter with those magnetic clumps inside the turbulent slab, and a nonzero variance of the Stokes parameter V can be generated. Furthermore, the linearly and circularly polarized photons in the optical and radio bands may suffer heavy absorptions from the slab. Thus we consider the polarized jitter radiation transfer processes. Finally, we compare our model results with the optical detections of GRB 091018, GRB 121024A, and GRB 131030A. We suggest simultaneous observations of GRB multi-wavelength polarization in the future.

  12. Business interest of Gazprom in the EU-27 in 2007

    Meijknecht, J.

    2008-04-01

    Gazprom is an important supplier of gas to the EU. Liberalisation of the EU gas market has also influenced the gas relations with Russia and the way the Russian Gas company Gazprom is securing its interest in this internal EU market. From a relationship of bilateral gas contracts with EU member states and their companies before gas market liberalisation, a new approach to secure its market share is beginning to evolve. The positioning of Gazprom in the EU market has raised concerns of EU policy makers. There is some trepidation that the investment strategy of Gazprom in the EU gas market will lead to a position of market dominance in an increasingly import dependent EU market. The discussion on Gazprom's market strategy needs to be fed with factual information on its activities and it is exactly what this new report is providing because information on the activities of Gazprom in the various member states' gas sector was incomplete. In this factual report in Dutch, the author presents a comprehensive oversight and characterisation of Gazprom's downstream assets in the EU-27. Through four layers - long-term contracts, company stakes, asset swaps and political support - a detailed insight is given in Gazprom's downstream activities in the EU-27. [nl

  13. Note: Design and implementation of a home-built imaging system with low jitter for cold atom experiments

    A novel home-built system for imaging cold atom samples is presented using a readily available astronomy camera which has the requisite sensitivity but no timing-control. We integrate the camera with LabVIEW achieving fast, low-jitter imaging with a convenient user-defined interface. We show that our system takes precisely timed millisecond exposures and offers significant improvements in terms of system jitter and readout time over previously reported home-built systems. Our system rivals current commercial “black box” systems in performance and user-friendliness.

    The purpose of this paper is the measurement of the relative intensities of the most intensive conversion lines of 152 Eu, the determination of as reliable as possible magnitudes of the intensities of γ-quanta using all the available data on γ-radiation of 152 Eu, the measurement of the interval conversion coefficients (ICC) for the most intensive γ-transitions, the determination of the probabilities of the 152 Eu β-decays to the 152 Sm and 152 Gd levels. The conversion lines of the most intensive γ-transitions in the 152 Eu decay are studied and the corresponding ICC are measured on the beta-spectrometers of π√2 and UMB type. The balance for the γ-transitions in the 152 Sm and 152 Gd daughter nuclei are presented. This balance is used to determine the absolute intensities of γ-rays (in terms of the percentage of the 152 Eu decays) and the probabilities of β-transitions to the levels of daughter nuclei. More accurate data on γ-rays and conversion electrons obtained can be used for the calibration of gamma and beta spectrometers

    In this paper I try to explore whether the EU can go on expanding and thereby become culturally ever more diversified, and at the same retain its stability. The answer is, in principle, affirmative. Europe has always been much diversified, and therefore it is not possible to define a European...... identity in terms of particular cultural traditions. However, in spite of their diversity, the EU-member countries are united by their adherence to the principles of democracy, rule by law and human rights.

An essential part is the willingness of member states to accept a reduction of national sovereignty on some important policy fields.

    2009-07-01

    Full Text Available There is much more to liberalism in the post communist context than has been acknowledged. A sizeable effort has indeed emerged to transplant a relatively coherent liberal ideology to the region, one exported not merely through the conditionality of international financial institutions, but also through the conditionality and socialization of organizations like the NATO, OSCE, EU, and the Council of Europe. ‘EU liberalism’ includes the ‘standard’ liberal emphasis on individual rights, the rule of law, constitutional democracy, freedom, and market economics as well as support for minority rights, and a seemingly schizophrenic emphasis on economic integration that involves, first bringing down borders for the free movement of people, goods, capital, and services between member states, and second, market regulation to diminish the social downsides of capitalism. This paper outlines EU liberalism’s emergence and its application to Central and East European countries.

    1994-01-01

    It is desired to design a predictive feedforward transverse jitter control system to control both angle and position jitter in pulsed linear accelerators. Such a system will increase the accuracy and bandwidth of correction over that of currently available feedback correction systems. Intrapulse correction is performed. An offline process actually ''learns'' the properties of the jitter, and uses these properties to apply correction to the beam. The correction weights calculated offline are downloaded to a real-time analog correction system between macropulses. Jitter data were taken at the Los Alamos National Laboratory (LANL) Ground Test Accelerator (GTA) telescope experiment at Argonne National Laboratory (ANL). The experiment consisted of the LANL telescope connected to the ANL ZGS proton source and linac. A simulation of the correction system using this data was shown to decrease the average rms jitter by a factor of two over that of a comparable standard feedback correction system. The system also improved the correction bandwidth

    2017-05-12

    The extraction bucket position in the Fermilab Booster is controlled with a cogging process that involves the comparison of the Booster rf count and the Recycler Ring revolution marker. A one rf bucket jitter in the ex-traction bucket position results from the variability of the process that phase matches the Booster to the Recycler. However, the new slow phase lock process used to lock the frequency and phase of the Booster rf to the Recycler rf has been made digital and programmable and has been modified to correct the extraction notch position. The beam loss at the Recycler injection has been reduced by 20%. Beam studies and the phase lock system will be discussed in this paper.

    Full Text Available The paper deals with the EU aid concerning to improved the economic situation from developing countries. Therefore, the aim of this research is to identify how EU states contribute to helping poor countries, members of the World Trade Organization. For the beginning, we define the EU’position before, during and after the Doha Round – a round of WTO multilateral trade negotiations. Moreover, we analyse the development dimension, focusing on countries „marginalized” until early of XXI century in terms of international trade, because this represents the idea-axis of the Doha Round. In this context, the EU – one of the leading global commercial players and a key member of the institution mentioned above – has set several objectives to achieve the basic goal of negotiations and several ways to support developing countries. To conclude, we propose to define the key points of the European aid for least developed and developing countries.

  10. EU environmental policy and competitiveness

    Directory of Open Access Journals (Sweden)

    Stojanović Boban

    2006-01-01

    Full Text Available Protection of the environment was not a specific importance to the Community although the Treaty of Rome expressly specified that "health, safety environmental protection" shall be based on "a high level of protection". In deciding upon a framework for a European environmental policy, the Community was also responding to increased public awareness of the problem and concerns about the state of the natural and man-made environment. During the past years, competitiveness concerns have dominated the EU policy debate, in the course of which a growing consensus is being developed on the importance of eco-innovations and resource efficiency for EU competitiveness and on the market opportunities they offer. There is an increasing evidence that environmental policy and eco-innovations can promote economic growth, as well as maintain and create jobs, contributing both to competitiveness and employment. Environmental constraints to rapid economic growth are increasingly recognized by countries, leading to a rising awareness of the need for sustainable development. Implementation of an environmental policy however, generates significant implications for competition among countries.

  11. The EU's Convergence Dilemma

    Directory of Open Access Journals (Sweden)

    Notermans Ton

    2015-02-01

    Full Text Available As economic stagnation continues to mark the EU in the fifth year of the euro zone crisis, political support for integration is waning. The European Parliament elections of 2014 returned a hitherto unparalleled number of Eurosceptic MEPs, with EU-critical parties becoming the largest ones in several Member States. Much of this Euroscepticism is driven by economic polarisation between core and peripheral countries. While an increasing number of voters in the northwestern creditor countries resent having to foot the bill for what they consider economic mismanagement in the periphery, voters in peripheral countries increasingly rebel against what they deem to be an economically catastrophic Diktat from Germany and its allies. Continued political support for European integration will hinge on successful income convergence in the EU but the current dilemma is that such policies might not be politically feasible. Periods of rapid convergence would seem to suggest that success depends on two main policy strategies. First, a monetary policy that promotes credit for productive purposes, leaves inflation control to other instruments, and employs selective credit rationing to prevent asset booms. Second, a vertical industrial policy prioritising selected industrial sectors. The first policy conflicts with the present framework of euro zone monetary policy, but that framework was only installed in the first place because many peripheral countries were desperately in search of an external constraint on domestic distributional conflict. Industrial policies, in turn, require a sufficient degree of state autonomy from business elites in order to be effective, but it is highly questionable whether most states in the EU possess such autonomy. Though there are, as yet hesitant, signs of a reorientation of both monetary and cohesion policy in the EU, the question of the institutional and political preconditions for their successful implementation has been largely

    Six SD bands were populated in {sup 143}Eu and {sup 144}Eu, two of which had not been previously observed. Sum spectra were generated to search for two step links from the yrast SD band in {sup 143}Eu. However, no two step links were found. A single link from the SD band in {sup 143}Eu was found at 3364 keV. The level where it feeds into has not been identified. Alpha-particle energy (E{sub {alpha}}) spectra leading to the SD band and to normal states in {sup 143}Eu were measured and a correlation was found between E{sub {alpha}} and the level spin of the residual nucleus.

  14. EuO and Gd-doped EuO thin films. Epitaxial growth and properties

    International Nuclear Information System (INIS)

    Sutarto, Ronny

    2009-01-01

    Europium oxide (EuO) based materials exhibit a wealth of spectacular phenomena, including half-metallic ferromagnetism, metal-insulator transition, colossal magneto-resistance, large magneto-optical Kerr effect, tunable ferromagnetic ordering temperatures, and large and long-lived photo-induced conductivity. These extraordinary properties make EuO an ideal candidate for implementation in device applications, in particular, for spintronics. Most of the work in the past has been carried out on bulk EuO, but for device applications it is preferred to have the EuO in thin lm form. A urry of studies have therefore emerged in the last decade in order to explore a wide variety of preparation routes and to investigate the properties of the resulting EuO thin films. A recent highlight is the demonstration that doped EuO films can be fabricated on Si and GaN, thereby exhibiting the expected spin-polarized transport effects. Nevertheless, it is still far from a trivial task to prepare EuO thin films with well de ned properties. For bulk EuO, it is already known that stoichiometry is the key issue, and that the presence of small amounts of defects or impurities quickly lead to very large deviations of the material properties. In fact, to make bulk EuO to be stoichiometric one needs temperatures as high as 1800 C. It is obvious that such high temperatures are not compatible with device engineering processes. The preparation of thin films must therefore involve much lower temperatures, preferably not higher than 400-500 C. The consequences are very dear. It turned out that many of the recent studies on EuO thin films are suffering from sample quality problems, due to the presence of, e.g., trivalent Eu species (Eu 3 O 4 , Eu 2 O 3 ), oxygen vacancies, or even Eu metal clusters. Controlled doping of the EuO with trivalent rare-earth ions is also not trivial, since most often even the actual doping concentrations were not known. In fact, one could also question in this respect the

    Nowadays, nano- and micro-satellites, which are smaller than conventional large satellites, provide access to space to many satellite developers, and they are attracting interest as an application of space development because development is possible over shorter time period at a lower cost. In most of these nano- and micro-satellite missions, the satellites generally must meet strict attitude requirements for obtaining scientific data under strict constraints of power consumption, space, and weight. In many satellite missions, the jitter of a reaction wheel degrades the performance of the mission detectors and attitude sensors; therefore, jitter should be controlled or isolated to reduce its effect on sensor devices. In conventional standard-sized satellites, tip-tilt mirrors (TTMs) and isolators are used for controlling or isolating the vibrations from reaction wheels; however, it is difficult to use these devices for nano- and micro-satellite missions under the strict power, space, and mass constraints. In this research, the jitter of reaction wheels is reduced by using accurate sensors, small reaction wheels, and slow rotation frequency reaction wheel instead of TTMs and isolators. The objective of a reaction wheel in many satellite missions is the management of the satellite's angular momentum, which increases because of attitude disturbances. If the magnitude of the disturbance is reduced in orbit or on the ground, the magnitude of the angular momentum that the reaction wheels gain from attitude disturbances in orbit becomes smaller; therefore, satellites can stabilize their attitude using only smaller reaction wheels or slow rotation speed, which cause relatively smaller vibration. In nano- and micro-satellite missions, the dominant attitude disturbance is a magnetic torque, which can be cancelled by using magnetic actuators. With the magnetic compensation, the satellite reduces the angular momentum that the reaction wheels gain, and therefore, satellites do

    2011-10-01

    Based on low-field magnetization measurements on a series of single crystals, we present a scheme of the Eu2+ spin alignment in EuFe2(As1-xPx)2. We explain observations of the Eu2+ ordering previously reported, reconciling different existing phase diagrams. The magnetic moments of the Eu2+ ions are slightly canted, yielding a ferromagnetic contribution along the c direction that becomes stronger with pressure, until superconductivity sets in. The spin-density wave as well as the superconducting phase coexist with an antiferromagnetic interlayer coupling of the canted spins. Reducing the interlayer distance finally leads to a ferromagnetic Eu2+ interlayer coupling and to the suppression of superconductivity.

    The generation of ultra-short electron bunches with ultra-low timing-jitter relative to the photo-cathode (PC) laser has been experimentally proved for the first time at the SPARC_LAB test-facility (INFN-LNF, Frascati) exploiting a two-stage hybrid compression scheme. The first stage employs RF-based compression (velocity-bunching), which shortens the bunch and imprints an energy chirp on it. The second stage is performed in a non-isochronous dogleg line, where the compression is completed resulting in a final bunch duration below 90 fs (rms). At the same time, the beam arrival timing-jitter with respect to the PC laser has been measured to be lower than 20 fs (rms). The reported results have been validated with numerical simulations.

    It is possible to use feedforward predictive control for transverse position and trajectory-angle jitter correction. The control procedure is straightforward, but creation of the predictive filter is not as obvious. The two process tested were the least mean squares (LMS) and Kalman filter methods. The controller parameters calculated offline are downloaded to a real-time analog correction system between macropulses. These techniques worked well for both interpulse (pulse-to-pulse) correction and intrapulse (within a pulse) correction with the Kalman filter method being the clear winner. A simulation based on interpulse data taken at the Stanford Linear Collider showed an improvement factor of almost three in the average rms jitter over standard feedback techniques for the Kalman filter. An improvement factor of over three was found for the Kalman filter on intrapulse data taken at the Los Alamos Meson Physics Facility. The feedforward systems also improved the correction bandwidth. copyright 1995 American Institute of Physics

    It is possible to use feedforward predictive control for transverse position and trajectory-angle jitter correction. The control procedure is straightforward, but creation of the predictive filter is not as obvious. The two processes tested were the least mean squares (LMS) and Kalman inter methods. The controller parameters calculated offline are downloaded to a real-time analog correction system between macropulses. These techniques worked well for both interpulse (pulse-to-pulse) correction and intrapulse (within a pulse) correction with the Kalman filter method being the clear winner. A simulation based on interpulse data taken at the Stanford Linear Collider showed an improvement factor of almost three in the average rms jitter over standard feedback techniques for the Kalman filter. An improvement factor of over three was found for the Kalman filter on intrapulse data taken at the Los Alamos Meson Physics Facility. The feedforward systems also improved the correction bandwidth

    This paper presents a 10-GHz low spur and low jitter phase-locked loop (PLL). An improved low phase noise VCO and a dynamic phase frequency detector with a short delay reset time are employed to reduce the noise of the PLL. We also discuss the methodology to optimize the high frequency prescaler's noise and the charge pump's current mismatch. The chip was fabricated in a SMIC 0.13-μm RF CMOS process with a 1.2-V power supply. The measured integrated RMS jitter is 757 fs (1 kHz to 10 MHz); the phase noise is -89 and -118.1 dBc/Hz at 10 kHz and 1 MHz frequency offset, respectively; and the reference frequency spur is below -77 dBc. The chip size is 0.32 mm 2 and the power consumption is 30.6 mW. (semiconductor integrated circuits)

    In pump-probe experiments employing a free-electron laser (FEL) in combination with a synchronized optical femtosecond laser, the arrival-time jitter between the FEL pulse and the optical laser pulse often severely limits the temporal resolution that can be achieved. Here, we present a pump-probe experiment on the UV-induced dissociation of 2,6-difluoroiodobenzene C 6 H 3 F 2 I) molecules performed at the FLASH FEL that takes advantage of recent upgrades of the FLASH timing and synchronization system to obtain high-quality data that are not limited by the FEL arrival-time jitter. Here, we discuss in detail the necessary data analysis steps and describe the origin of the time-dependent effects in the yields and kinetic energies of the fragment ions that we observe in the experiment.

    The performance of railgap switch critically relies upon multichannel breakdown between the extended electrodes (rails) in order to ensure distributed current transfer along electrode length and to minimize the switch inductance. The initiation of several simultaneous arc channels along the switch length depends on the gap triggering technique and on the rate at which the electric field changes within the gap. This paper presents design, construction, and output characteristics of a coaxial cable based three-stage transmission line transformer (TLT) that is capable of initiating multichannel breakdown in a high voltage, low inductance railgap switch. In each stage three identical lengths of URM67 coaxial cables have been used in parallel and they have been wounded in separate cassettes to enhance the isolation of the output of transformer from the input. The cascaded output impedance of TLT is ~50 Ω. Along with multi-channel formation over the complete length of electrode rails, significant reduction in jitter (≤2 ns) and conduction delay (≤60 ns) has been observed by the realization of large amplitude (~80 kV), high dV/dt (~6 kV/ns) pulse produced by the indigenously developed TLT based trigger generator. The superior performance of TLT over conventional pulse transformer for railgap triggering application has been compared and demonstrated experimentally.

    The effect of temperature on the luminescence properties of LiMgPO 4 doped with Eu 3+ and Eu 2+ are presented. Depending on the excitation wavelength, luminescence spectra consist of two distinct broad emission bands peaking at 380 nm and 490 nm related to 4f 6 5d 1  → 4f 7 ( 8 S 7/2 ) luminescence of Eu 2+ and to europium-trapped exciton, respectively, and/or several sharp lines between the 580 nm and 710 nm region, ascribed to the 5 D 0  →  7 F J (J = 0, 1, 2, 3 and 4) transitions in Eu 3+ . To explain all the features of the Eu 2+ and Eu 3+ luminescence we discussed the existence of two different Eu sites substituting for Li + , with short and long distance compensation. The evident effect of increasing the intensity of the Eu 2+ luminescence with increasing temperature was observed. It was considered that the charge compensation mechanism for Eu 3+ and Li + as well as Eu 2+ replacing Li + in the LiMgPO 4 is a long distance compensation that allows for the existence of some of the europium ions either as Eu 3+ at low temperature or as Eu 2+ at high temperature. We concluded that Eu 2+ in the Li + site with long distance compensation yields only 4f 6 5d 1  → 4f 7 luminescence, whereas Eu 2+ in the Li + site with short distance compensation yields 4f 6 5d 1  → 4f 7 luminescence and europium-trapped exciton emission.

    Full Text Available This article provides a critical review of the “terms” of the ongoing EU enlargement, in the light of the European public interest. The European public interest ought to include the prospective (Central European members, within a perspective of an enlarged Union in 2010, or so. The following forms a personalised summary of a major report published (in Dutch in September 2001 by the WRR in The Hague (a think-tank, formally under the Dutch Prime Minister, but by statute fully independent. The author was one of the lead-writers of this report. The present article merely focuses on the policy recommendations of the report. It is hoped that these kinds of critical analyses will help to stimulate solid policy debate on the EU in Romania, on the road to EU membership. The article discusses why the notion of a “core-acquis” would improve the enlargement strategy; the application of the core acquis to the internal market, environment and justice and home affairs; judicial and administrative capacity; accession to “euro-land”; the rapid reform of the CAP; a reform of “cohesion” approaches; and a note on the EU budgetary implications.

    Full Text Available The results of the Vilnius summit of the EaP project and the consequent Ukrainian crisis with major international effects make possible questioning about the eventual scenarios of the EU eastern politics and possible configurations ofinternational interactions. The article elaborates on the key elements and trends of the EU activities at the post-soviet space that are likely to frame the context of its further developments. The most visible trends analysed here are the extreme differentiation of bilateral relations within the EaP project alongside with the growing symbolism of official rhetoric and program practices of the European Union. As a result, we see the EU's intention to narrow the geographical and qualitative field of its activities on the eastern directionwith saving the shell of the EaP for nominal functioning. Such tactics is not likely to result in a drastic change of the model of conflict dependencies in the "shared neighbourhood". The article analyses key misperceptions of the actors involved in the complex of interactions in the region. The structure is complicated by the deepening and widening of Russia-lead Eurasian integration project. Current crisis of the EU eastern policy is considered to derive from the exaggeration of the value-based, normative aspect of the common foreign policy in general and will have the systemic consequences both for the European external actions and for its internal developments.

  11. Jitter Studies for a 2.4 GeV Light Source Accelerator Using LiTrack

    Electron beam quality is an important factor in the performance of a free electron laser (FEL). Parameters of particular interest are the electron beam energy, slice emittance and energy spread, peak current, and energy chirp. Jitter in average energy is typically many times the slice energy spread. A seeded FEL is sensitive not only to these local properties but also to factors such as shot-to-shot consistency and the uniformity of the energy and current profiles across the bunch. The timing and bunch length jitter should be controlled to maximize the interval of time over which the electron beam can be reliably seeded by a laser to produce good output in the FEL. LiTrack, a one-dimensional tracking code which includes the effect of longitudinal wakefields, is used to study the sensitivity of the accelerator portion of a 2.4 GeV FEL to sources of variability such as the radio frequency (RF) cavities, chicanes, and the timing and efficiency of electron production at the photocathode. The main contributors to jitter in the resulting electron beam are identified and quantified for various figures of merit.

    Full Text Available In this paper we propose a scheme that allows a strong reduction of the timing jitter between the pulses of a free electron laser (FEL and external laser pulses delivered simultaneously at the FEL experimental stations for pump-probe–type experiments. The technique, applicable to all seeding-based FEL schemes, relies on the free-space optical transport of a portion of the seed laser pulse from its optical table to the experimental stations. The results presented here demonstrate that a carefully designed laser beam transport, incorporating also a transverse beam position stabilization, allows one to keep the timing fluctuations, added by as much as 150 m of free space propagation and a number of beam folding mirrors, to less than 4 femtoseconds rms. By its nature our scheme removes the major common timing jitter sources, so the overall jitter in pump-probe measurements done in this way will be below 10 fs (with a margin to be lowered to below 5 fs, much better than the best results reported previously in the literature amounting to 33 fs rms.

    2010-01-01

    A low-jitter RF phase locked loop (PLL) frequency synthesizer with high-speed mixed-signal down-scaling circuits is proposed. Several techniques are proposed to reduce the design complexity and improve the performance of the mixed-signal down-scaling circuit in the PLL. An improved D-latch is proposed to increase the speed and the driving capability of the DMP in the down-scaling circuit. Through integrating the D-latch with 'OR' logic for dual-modulus operation, the delays associated with both the 'OR' and D-flip-flop (DFF) operations are reduced, and the complexity of the circuit is also decreased. The programmable frequency divider of the down-scaling circuit is realized in a new method based on deep submicron CMOS technology standard cells and a more accurate wire-load model. The charge pump in the PLL is also realized with a novel architecture to improve the current matching characteristic so as to reduce the jitter of the system. The proposed RF PLL frequency synthesizer is realized with a TSMC 0.18-μm CMOS process. The measured phase noise of the PLL frequency synthesizer output at 100 kHz offset from the center frequency is only -101.52 dBc/Hz. The circuit exhibits a low RMS jitter of 3.3 ps. The power consumption of the PLL frequency synthesizer is also as low as 36 mW at a 1.8 V power supply. (semiconductor integrated circuits)

  20. Electronic transport through EuO spin-filter tunnel junctions

    2012-11-12

    Epitaxial spin-filter tunnel junctions based on the ferromagnetic semiconductor europium monoxide (EuO) are investigated by means of density functional theory. In particular, we focus on the spin transport properties of Cu(100)/EuO(100)/Cu(100) junctions. The dependence of the transmission coefficient and the current-voltage curves on the interface spacing and EuO thickness is explained in terms of the EuO density of states and the complex band structure. Furthermore, we also discuss the relation between the spin transport properties and the Cu-EuO interface geometry. The level alignment of the junction is sensitively affected by the interface spacing, since this determines the charge transfer between EuO and the Cu electrodes. Our calculations indicate that EuO epitaxially grown on Cu can act as a perfect spin filter, with a spin polarization of the current close to 100%, and with both the Eu-5d conduction-band and the Eu-4f valence-band states contributing to the coherent transport. For epitaxial EuO on Cu, a symmetry filtering is observed, with the Δ1 states dominating the transmission. This leads to a transport gap larger than the fundamental EuO band gap. Importantly, the high spin polarization of the current is preserved up to large bias voltages.

    Full Text Available Temporally localized distortions account for the highest variance in subjective evaluation of coded speech signals (Sen (2001 and Hall (2001. The ability to discern and decompose perceptually relevant temporally localized coding noise from other types of distortions is both of theoretical importance as well as a valuable tool for deploying and designing speech synthesis systems. The work described within uses a physiologically motivated cochlear model to provide a tractable analysis of salient feature trajectories as processed by the cochlea. Subsequent statistical analysis shows simple relationships between the jitter of these trajectories and temporal attributes of the Diagnostic Acceptability Measure (DAM.

    Full Text Available This article analyzes the link between culture and diplomacy between Russia and the European Union, and shows the importance of cultural relations. It examines the common space of science, education and culture introduced at the 2003 EU-Russia Summit in St. Petersburg and the application of the principles of this concept that were established at the 2005 EU-Russia Summit in Moscow. It then considers EU-Russia collaboration on humanitarian action and the challenges that both parties face in this sphere. It also explains the formation of EU domestic and foreign cultural policy, and the role of European institutions and states in cultural affairs and diplomacy, as well as key elements and mechanisms of contemporary Russian foreign cultural policy. In addition, the article focuses on the European side of post-Soviet EU-Russia cultural relations. This cultural collaboration is defined as a competitive neighbourhood. EU and Russian interests collide: while Europeans try to promote their values, norms and standards within the framework of the European Neighbourhood Policy, Russia seeks to culturally influence and engage in this region for geostrategic and historical reasons. Finally, the article assesses the prospects for the EU-Russia cultural relations and emphasizes the role of ideology in improving such relations.

  4. Banning banking in EU emissions trading?

    2006-01-01

    Admitting banking in emissions trading systems reduces overall compliance costs by allowing for inter-temporal flexibility: cost savings can be traded over time. However, unless individual EU Member States (MS) decide differently, the transfer of unused allowances from the period of 2005-2007 into the first commitment period under the Kyoto Protocol, i.e. 2008-2012, will be prohibited. In this paper, we first explore the implications of such a ban on banking when initial emission targets are lenient. This analysis is based on a simulation which was recently carried out in Germany with companies and with a student control group. The findings suggest that a EU-wide ban on banking would lead to efficiency losses in addition to those losses which arise from the lack of inter-temporal flexibility. Second, we use simple game-theoretic considerations to argue that, under reasonable assumptions, such a EU-wide ban on banking will be the equilibrium outcome. Thus, to avoid a possible prisoners' dilemma, MS should have co-ordinated their banking decisions

In this study we reduce the jitter of the TDC by using two different approaches: one uses an on-chip clock generator with an on-chip low-pass filter for reducing the noise in the bias current, and the other uses a low-jitter external clock source at room temperature. We confirmed that the jitter is reduced to less than 100 ps in the latter approach

    Full Text Available In recent years European Commission has developed a set of documents for Members States tracing, directly or indirectly, recommendations for the transformation of the European city. The paper wants to outline which future EU draws for the city, through an integrated and contextual reading of addresses and strategies contained in the last documents, a future often suggested as Smart City. Although the three main documents (Cohesion Policy 2014-2020 of European Community, Digital Agenda for Europe and European Urban Agenda face the issue of the future development of European cities from different points of view, which are respectively cohesion social, ICT and urban dimension, each of them pays particular attention to urban and territorial dimension, identified by the name of Smart City. In other words, the paper aims at drawing the scenario of evolution of Smart Cities that can be delineated through the contextual reading of the three documents. To this end, the paper is divided into three parts: the first part briefly describes the general contents of the three European economic plan tools; the second part illustrates the scenarios for the future of the European city contained in each document; the third part seeks to trace the evolution of the Smart Cities issue developed by the set of the three instruments, in order to provide the framework of European Community for the near future of our cities.

    Full Text Available The article is dedicated to implementation of the enhanced cooperation in the EU. Actually two such projects are шn progress (the law applicable to divorce and legal separation and unitary patent protection and other two are under discussionffmandai transaction tax and European Public Prosecutor's Office. Active use of the enhanced cooperation recently shows that such kind of the promoting integration is more and more required in the EU. However its implementation can jeopardize the principles of the EU functioning and undermine the status of the institutions in the integration process. This mechanism can also be used in order to exclude the discordant states from integration process instead of traditional search of compromises. This argument is based on analysis of the implementation conditions of the project on the unitary patent protection. At the same time the projects of the enhanced cooperation obviously make the interaction in different spheres more efficient. In addition they can be used for testing the new types of cooperation. That's why the search for an optimal balance between promotion integration through the mechanism of enhanced cooperation and preserving the unity of the EU should be considered as main goal by participants of the integration process. Otherwise the gradual separation on the vanguard group may lead to EU division. Nevertheless taking into consideration enlargement of the EU and its diversity, the enhanced cooperation Should be used onlyas "extreme measure".

    Full Text Available The impact of the international economic crisis on new EU member states has proven to be more severe than the first estimates of the economic analysts. The situation is different for each Member State, the nature and the dimension of the challenges faced are not identical, and the pace of reform is not the same. The economic crisis has prompted intense and sustained action by the EU's national governments, the European Central Bank and the Commission. All have been working closely together to support growth and employment, ensure financial stability, and put in place a better governance system for the future. Sustainable development in the future is the common responsibility of all Member States and EU institutions, because our economies are closely interlinked, and the EU economic governance now reconfigured to provide more effective responses at the policy level, to give a good reaction to the present and the future challenges.

    2014-01-01

    Full Text Available This paper examines the concepts of spouse, civil partner and partner in European Union (EU law, particularly in regulations referring to the free movement of persons, criticizing the unharmonized approach to defining family in this context. It argues that the narrow interpretation of the term spouse could lead to discrimination on the grounds of sexual orientation. Likewise, grounding free movement rights of civil partners on host state recognition of such partnerships could lead to the same result, which is not compatible with the equality principle in the EU law. The position of unmarried or unregistered partners is also considered; in particular, the paper analyses the requirement to duly attest durability of the relationship and its impact on the same-sex partners wishing to immigrate to a Member State. The author holds that it is necessary to reconsider the law in this area and adjust it to the EU's efforts to eliminate discrimination on the grounds of sexual orientation.

    We show that a 1.13 GHz repetition rate optical pulse train with 0.70 fs high-frequency timing jitter (integration bandwidth of 17.5 kHz-10 MHz, where the measurement instrument-limited noise floor contributes 0.41 fs in 10 MHz bandwidth) can be directly generated from a free-running, single-mode diode-pumped Yb:KYW laser mode-locked by single-wall carbon nanotube-coated mirrors. To our knowledge, this is the lowest-timing-jitter optical pulse train with gigahertz repetition rate ever measured. If this pulse train is used for direct sampling of 565 MHz signals (Nyquist frequency of the pulse train), the jitter level demonstrated would correspond to the projected effective-number-of-bit of 17.8, which is much higher than the thermal noise limit of 50 Ω load resistance (~14 bits).

  12. Renewable energies in the EU-Accession States

    2006-01-01

    The aim of this article is to discuss obstacles and success conditions for renewable energy sources in the EU-Accession States and to compare them with the framework in the EU-15. Besides the ten states which will join the EU in 2004, Bulgaria and Romania which will probably join in 2007 as well as Turkey are analysed. Most of these countries have had a century-long tradition in the utilisation of RES, primarily in biomass and hydropower. However, the communist regimes were convinced of the superiority of large-scale systems and converted the energy sectors into centralised units. Due to this dominating belief system more decentralised applications such as installations using renewable energies had to close. One crucial driving force for future renewable energy development in the Accession States comes from the stipulations set by the EU. The EU-Directive on the promotion of electricity produced from RES gives the new EU-members targets for their RES-development until 2010. Due to the Directive many Accession States have already begun to pay more attention to the topic and to introduce more systematic policies. Six of the Accession States have introduced minimum tariffs which were one of the main success conditions (besides a stable and sound investment programme as well as favourable background conditions) in the leading wind energy countries Germany and Spain. Beside the external pressure by the EU and other international obligations other driving forces such as the path dependencies in the national energy policies (degree of coal, oil and gas exploitation, nuclear power use, import dependency), the political support schemes for renewable energies, possibilities of obtaining external financial support and the cognitive environment are discussed. Finally similarities and differences between EU-15 and Accession States are worked out

  13. Effect of Eu magnetism on the electronic properties of the candidate Dirac material EuMnBi2

    May, Andrew F.; McGuire, Michael A.; Sales, Brian C.

    2014-08-01

    The crystal structure and physical properties of the layered material EuMnBi2 have been characterized by measurements on single crystals. EuMnBi2 is isostructural with the Dirac material SrMnBi2 based on single-crystal x-ray diffraction, crystallizing in the I4/mmm space group (No. 139). Magnetic susceptibility measurements suggest antiferromagnetic (AFM) ordering of moments on divalent Eu ions near TN=22 K. For low fields, the ordered Eu moments are aligned along the c axis, and a spin flop is observed near 5.4 T at 5 K. The moment is not saturated in an applied field of 13 T at 5 K, which is uncommon for compounds containing Eu2+. The magnetic behavior suggests an anisotropy enhancement via interaction between Eu and the Mn moments that appear to be ordered antiferromagnetically below ≈310 K. A large increase in the magnetoresistance is observed across the spin flop, with absolute magnetoresistance reaching ≈650% at 5 K and 12 T. Hall effect measurements reveal a decrease in the carrier density below TN, which implies a manipulation of the Fermi surface by magnetism on the sites surrounding the Bi square nets that lead to Dirac cones in this family of materials.

    2013-04-15

    In 2020, some leading EU energy and climate policies will expire. At present, the EU and its Member States are discussing the design of a post-2020 policy portfolio. In a discussion paper commissioned by the European Copper Institute, Ecofys shows that an EU-wide renewable energy target is a necessary part of a 2030 portfolio. The paper analyses, in detail, two realistic policy portfolio options for renewable energy, target-setting in particular: one 'decarbonisation-only' EU target with voluntary national targets for renewable energy, and one that includes an EU-wide renewable energy target, broken down into binding national targets. The analysis shows that the latter option, when supported by appropriate and improved EU and Member States' policies and measures, is most suitable in facilitating a European low-carbon economy.

    Intense ultrashort pulse lasers are used for fs resolution pump-probe experiments more and more at large scale facilities, such as free electron lasers (FEL). Measurement of the arrival time of the laser pulses and stabilization to the machine or other sub-systems on the target, is crucial for high time-resolution measurements. In this work we report on a single shot, spectrally resolved, non-collinear cross-correlator with sub-fs resolution. With a feedback applied we keep the output of the TW class Ti:sapphire amplifier chain in time with the seed oscillator to ~3 fs RMS level for several hours. This is well below the typical pulse duration used at FELs and supports fs resolution pump-probe experiments. Short term jitter and long term timing drift measurements are presented. Applicability to other wavelengths and integration into the timing infrastructure of the FEL are also covered to show the full potential of the device.

  1. A Conflict-Free Low-Jitter Guaranteed-Rate MAC Protocol for Base-Station Communications in Wireless Mesh Networks

    Science.gov (United States)

    Szymanski, T. H.

    A scheduling algorithm and MAC protocol which provides low-jitter guaranteed-rate (GR) communications between base-stations (BS) in a Wireless Mesh Network (WMN) is proposed. The protocol can provision long-term multimedia services such as VOIP, IPTV, or Video-on-Demand. The time-axis is partitioned into scheduling frames with F time-slots each. A directional antennae scheme is used to provide each directed link with a fixed transmission rate. A protocol such as IntServ is used to provision resources along an end-to-end path of BSs for GR sessions. The Guaranteed Rates between the BSs are then specified in a doubly stochastic traffic rate matrix, which is recursively decomposed to yield a low-jitter GR frame transmission schedule. In the resulting schedule, the end-to-end delay and jitter are small and bounded, and the cell loss rate due to primary scheduling conflicts is zero. For dual-channel WMNs, the MAC protocol can achieve 100% utilization, as well as near-minimal queueing delays and near minimal delay jitter. The scheduling time complexity is O(NFlogNF), where N is the number of BSs. Extensive simulation results are presented.

    Full Text Available Single fiber electromyography (SFEMG is the most sensitive clinical neurophysiological test for neuromuscular junction disorders, particularly myasthenia gravis. Normal values for jitter obtained with SFEMG electrode have been published, but there are few publications for concentric needle electrode (CNE. The aim of this study was to discuss the possibilities to analyse the jitter in CNE recordings and to get normal values of jitter for voluntary activated Extensor Digitorum Communis using disposable CNE. Fifty normal subjects were studied, 16 male and 34 female with a mean age of 37.1±10.3 years (19-55. The jitter values of action potentials pairs of isolated muscular fibers were expressed as the mean consecutive difference (MCD after 20 analysed potential pairs. The mean MCD (n=50 obtained was 24.2±2.8 µs (range of mean values in each subject was 18-31. Upper 95% confidence limit is 29.8 µs. The mean jitter of all potential pairs (n=1000 obtained was 24.07±7.30 µs (range 9-57. A practical upper limit for individual data is set to 46 µs. The mean interpotential interval (MIPI was 779±177 µs (range of individual mean values was 530-1412; there were no potentials with impulse blocking. The present study confirms that CNE is suitable for jitter analysis although certain precautions must be mentioned. Our findings of jitter values with CNE were similar to some other few reports in literature.Eletromiografia de fibra única (SFEMG é o método eletrofisiológico mais sensível para diagnóstico das desordens de junção neuromuscular, particularmente miastenia gravis.

    Russia and the European Union have clearly entered a new stage in their energy relations, defined by a growing asymmetry between a strengthened national monopoly on the supply side and a gradual opening of markets in Europe. In this context, a multitude of new approaches to EU Russia energy relations have been voiced recently by a wide variety of experts. Unfortunately, many of them involve 'defensive' solutions, driven by lack of mutual trust on both sides. Is a positive approach nevertheless still possible? The paper argues that competition is a key universal value in the development of a new and sustainable energy relationship between Russia and Europe. It is clear that EU competition regulators should take the lead in setting up a new framework for EU-Russia energy relations in the future. The success of their endeavors will not only determine the security of energy supply for European consumers, but also that of the Russian and Eurasian energy markets. (author)

    Full Text Available National governments are keenly aware of the need for investment in space. Canada, as a formal cooperating state in the European Space Agency (ESA, and Germany, as a leading member state of ESA, are interlinked in Europe’s space endeavours. Beyond ESA, Germany and Canada additionally have a strong history of bilateral cooperation on a range of space projects. This paper discusses the novel interdependencies between clear national and now supranational space policies, using the examples of the Canada-European Union (EU Comprehensive Economic and Trade Agreement (CETA. The agreement covers most aspects of the EU-Canada bilateral economic relationship and includes space. The paper focuses on international space policies, strategic bilateral co-operation, and technical accomplishments. It takes a closer look at German-Canadian collaboration in space programs and offers some reflection on the effect of both the EU and ESA’S transatlantic involvement in space.

    A trend towards automation of scientific research has recently resulted in what has been termed "data-driven inquiry" in various disciplines, including physics and biology. The automation of many tasks has been identified as a possible future also for the humanities and the social sciences, particularly in those disciplines concerned with the analysis of text, due to the recent availability of millions of books and news articles in digital format. In the social sciences, the analysis of news media is done largely by hand and in a hypothesis-driven fashion: the scholar needs to formulate a very specific assumption about the patterns that might be in the data, and then set out to verify if they are present or not. In this study, we report what we think is the first large scale content-analysis of cross-linguistic text in the social sciences, by using various artificial intelligence techniques. We analyse 1.3 M news articles in 22 languages detecting a clear structure in the choice of stories covered by the various outlets. This is significantly affected by objective national, geographic, economic and cultural relations among outlets and countries, e.g., outlets from countries sharing strong economic ties are more likely to cover the same stories. We also show that the deviation from average content is significantly correlated with membership to the eurozone, as well as with the year of accession to the EU. While independently making a multitude of small editorial decisions, the leading media of the 27 EU countries, over a period of six months, shaped the contents of the EU mediasphere in a way that reflects its deep geographic, economic and cultural relations. Detecting these subtle signals in a statistically rigorous way would be out of the reach of traditional methods. This analysis demonstrates the power of the available methods for significant automation of media content analysis.

    Ligand L, based on two do3a moieties linked by the methylene groups of 6,6'-dimethyl-2,2'-bipyridine, was synthesized and characterized. The addition of Ln salts to an aqueous solution of L (0.01 M Tris-HCl, pH 7.4) led to the successive formation of [LnL] and [Ln(2)L] complexes, as evidenced by UV/Vis and fluorescence titration experiments. Homodinuclear [Ln(2)L] complexes (Ln = Eu, Gd, Tb, Yb, and Lu) were prepared and characterized. The (1)H and (13)C NMR spectra of the Lu and Yb complexes in D(2)O solution (pD = 7.0) showed C(1) symmetry of these species in solution, pointing to two different chemical environments for the two lanthanide cations. The analysis of the chemical shifts of the Yb complex indicated that the two coordination sites present square antiprismatic (SAP) coordination environments around the metal ions. The spectroscopic properties of the [Tb(2)L] complex upon ligand excitation revealed conventional behavior with τ(H2O) = 2.05(1) ms and ϕ(H2O) = 51%, except for the calculation of the hydration number obtained from the luminescent lifetimes in H(2)O and D(2)O, which pointed to a non-integer value of 0.6 water molecules per Tb(III) ion. In contrast, the Eu complex revealed surprising features such as: 1) the presence of two and up to five components in the (5)D(0)→(7)F(0) and (5)D(0)→(7)F(1) emission bands, respectively; 2) marked differences between the normalized spectra obtained in H(2)O and D(2)O solutions; and 3) unconventional temporal evolution of the luminescence intensity at certain wavelengths, the intensity profile first displaying a rising step before the occurrence of the expected decay. Additional spectroscopic experiments performed on [Gd(2-x)Eu(x)L] complexes (x = 0.1 and 1.9) confirmed the presence of two distinct Eu sites with hydration numbers of 0 (site I) and 2 (site II), and showed that the unconventional temporal evolution of the emission intensity is the result of an unprecedented intramolecular Eu-to-Eu

    In this study, we report the comparison between Eu 3+ -doped silica nanoparticles synthesized by Stoeber method using Eu(NO 3 ) 3 or Eu(acac) 3 as precursors. The impact of different europium species on the properties of the final silica nanospheres is investigated in details in terms of size, morphology, reachable doping amount, and luminescence efficiency. Moreover, the results obtained for different thermal treatments are presented and discussed. It is shown that the organic complex modify the silica growing process, leading to bigger and irregular nanoparticles (500-800 nm) with respect to the perfectly spherical ones (400 nm) obtained by the nitrate salt, but their luminescence intensity and lifetime is significantly higher when 800-900 o C annealing is performed.

    Full Text Available The present article aims to explore the general theme of the EU enlargement strategy in the new 2012 European context. Until now, the EU’s enlargement strategy has yielded impressive results. It succeeded in transforming ten central and eastern European countries from post-communism confusion into open-market, mature and effective systems of democratic governments, and even on the economic front, they have also made astonishing progress. It is no doubt that people in the new EU countries live better then before. In this context, the EU must continue the enlargement process to help stabilize the Balkan region that lie beyond its expanded eastern border. No one can deny that major issues concerning western Balkan countries’ accession are still on the table, and they even exert a geopolitical influence of sorts. This makes it all the more important to see stability and regional co-operation there are strategically vital. An all-out effort must now be made to complete the enlargement process and ensure there is no strategic vacuum. This article provides the framework of analyses for the EU problems and the challenges for the Balkans governments as for Brussels.

    A new method of the absolute measurement for 152 Eu was established based on the 4πβ-γ spectroscopic anti-coincidence method. It is a coincidence counting method consisting of a 4πβ-counter and a Ge(Li) γ-ray detector, in which the effective counting efficiencies of the 4πβ-counter for β-rays, conversion electrons, and Auger electrons were obtained by taking the intensity ratios for certain γ-rays between the single spectrum and the spectrum coincident with the pulses from the 4πβ-counter. First, in order to verify the method, three different methods of the absolute measurement were performed with a prepared 60 Co source to find excellent agreement among the results deduced by them. Next, the 4πβ-γ spectroscopic coincidence measurement was applied to 152 Eu sources prepared by irradiating an enriched 151 Eu target in a reactor. The result was compared with that obtained by the γ-ray spectrometry using a 152 Eu standard source supplied by LMRI. They agreed with each other within the error of 2%. (author)

    We describe the results of x-ray absorption experiments carried out to deduce structural and chemical information in Eu(3+) doped, transparent, oxyfluoride glass and nanostructured glass-ceramic samples. The spectra were measured at the Pb and Eu-L(III) edges. The Eu environment in the glass samples is observed to be similar to that of EuF(3). Complementary x-ray diffraction experiments show that thermal annealing creates β-PbF(2) type nanocrystals. X-ray absorption indicates that Eu ions act as seeds in the nanocrystal formation. There is evidence of interstitial fluorine atoms around Eu ions as well as Eu dimers. X-ray absorption at the Pb-L(III) edge shows that after the thermal treatment most lead atoms form a PbO amorphous phase and that only 10% of the lead atoms remain available to form β-PbF(2) type nanocrystals. Both x-ray diffraction and absorption point to a high Eu content in the nanocrystals. Our study suggests new approaches to the oxyfluoride glass-ceramic synthesis in order to further improve their properties.

The size of the portal and the volume of the interior cavities of CB(n)s are dependent on the number of glycoluril units present in CBs. CBs are widely used as supramolecular host systems in applications, such as formation of supramolecular hydrogels, drug delivery systems. Though the binding of CBs with organic guest molecules have been studied extensively where as metal complexation studies are very few. In the present work, complexation studies of Cucurbit(7)uril (with seven glycouril units, CB7) with Eu(III) were carried out using fluorescence, UV-vis spectrophotometry. The stability constant for 1:1 complex CB7-Eu(III) complex determined by monitoring the change in CB7 UV- vis absorption spectra on addition of Eu(III) was found to be 2.99 ± 0.08. The fluorescence spectra of increasing ligand to metal ratio exhibited the increase in the intensity ratio of peak at 616 and 592 which is the measure of complexation of Eu(III) with CB7 and was used to deduce the stability constant and the value (2.82 ± 0.07) obtained was in good agreement with that obtained from UV vis spectroscopy. Further, the life time of Eu(III) ion, which increased with CB7 to Eu(III) ratio, was used to deduce number of water molecules around Eu(III) metal ion which were found to decrease from 9 to 3 thereby suggesting inner sphere complexation. The stability constant of CB7 with Eu(III) is one order of magnitude less than CB5, derived in separate study by authors. The smaller cavity of CB5 (2.4 A 0 ) favors its interactions with Eu(III) ion of comparable diameter (2.16 A 0 ) leading to higher stability constant compared to CB7 (5.4 A 0 ) having larger cavity

    We have studied the valence behavior of rare-earth ions, in particular Eu-ions, in a cubic intermetallic compound Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}B{sub 0.5} which is a homogeneous solid solution of two mixed-valent compounds CePd{sub 3} and EuPd{sub 3}B. Results of {sup 151}Eu Moessbauer spectroscopic measurements show that two different valence states, i.e., divalent- and trivalent-like states of Eu-ions exist in the compound. The possible reason for the observed heterogeneous valency vis-a-vis the variation in the chemical environment and the number of nearest-neighbor B atoms surrounding the Eu-ions has been discussed. Our results demonstrate that B incorporation in such Eu-based cubic intermetallic compounds leads to a situation where heterogeneous-valence state of Eu-ions is an energetically favorable ground state. - Highlights: > Intermetallic compound Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}B{sub 0.5} crystallizes in a single phase. > Eu-ions in Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}B{sub 0.5} are charge-ordered compared to +2.3 valency in Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}. > B incorporation makes charge-ordered state of Eu-ions energetically more favorable. > Nearest-neighbor chemical environment affects the Eu valency.

    Full Text Available Considering the EU adhesion, good governance has been analyzed from different perspectives, in the judicial literature being an analytic model or a normative concept. Some authors have wondered if this concept is a fashion, comprising some older ideas and principles, while other authors have asserted that the reasons why different methods of governance appear in the EU are based on “the complexity and the uncertainty of the problems on the agenda, an irreducible, the new approaches on public administration and law, hidden competencies, legitimacy and subsidiarity”. At a normative level, the White Paper of European Governance consecrated five principles on which good governance is based upon: openness, participation, responsibility, efficiency and coherence.

    development of small and medium-sized businesses in the EU countries. Practical importance is that the results of this study will lead to a wider acquaintance with progressive strategic methods of management of small and medium-sized enterprises. This will enable the plan development of concrete actions to improve the efficiency of enterprise management in less developed countries. In turn, raising awareness on this issue will reduce the number of inefficient and non-innovative enterprises. Scientific novelty of the article is to determine the theoretical basis of the differences that at the current development stage are increasingly manifested as certain contradictions in the compilation and improvement of small and medium-sized enterprises, development of strategies at the national and regional levels. Small and medium-sized enterprises, in their turn, have a wider access to their development. Conclusions. As a result of the main development strategies of small and medium-sized enterprises of the EU countries, there should be identified the differences and common features of different strategies for innovations of small and medium-sized enterprises. The interaction of the national and regional strategy with actual results and existing strategies is explored.

  11. Asymmetric dual-loop feedback to suppress spurious tones and reduce timing jitter in self-mode-locked quantum-dash lasers emitting at 155 μm

    We demonstrate an asymmetric dual-loop feedback scheme to suppress external cavity side-modes induced in self-mode-locked quantum-dash lasers with conventional single and dual-loop feedback. In this letter, we achieved optimal suppression of spurious tones by optimizing the length of second delay time. We observed that asymmetric dual-loop feedback, with large (~8x) disparity in cavity lengths, eliminates all external-cavity side-modes and produces flat RF spectra close to the main peak with low timing jitter compared to single-loop feedback. Significant reduction in RF linewidth and reduced timing jitter was also observed as a function of increased second feedback delay time. The experimental results based on this feedback configuration validate predictions of recently published numerical simulations. This interesting asymmetric dual-loop feedback scheme provides simplest, efficient and cost effective stabilization of side-band free optoelectronic oscillators based on mode-locked lasers.

  12. Automated jitter correction for IR image processing to assess the quality of W7-X high heat flux components

    2009-01-01

    An automated IR image processing method was developed to evaluate the surface temperature distribution of cyclically loaded high heat flux (HHF) plasma facing components. IPP Garching will perform the HHF testing of a high percentage of the series production of the WENDELSTEIN 7-X (W7-X) divertor targets to minimize the number of undiscovered uncertainties in the finally installed components. The HHF tests will be performed as quality assurance (QA) complementary to the non-destructive examination (NDE) methods used during the manufacturing. The IR analysis of an HHF-loaded component detects growing debonding of the plasma facing material, made of carbon fibre composite (CFC), after a few thermal cycles. In the case of the prototype testing, the IR data was processed manually. However, a QA method requires a reliable, reproducible and efficient automated procedure. Using the example of the HHF testing of W7-X pre-series target elements, the paper describes the developed automated IR image processing method. The algorithm is based on an iterative two-step correlation analysis with an individually defined reference pattern for the determination of the jitter.

  13. Implementing BosonSampling with time-bin encoding: Analysis of loss, mode mismatch, and time jitter

    Science.gov (United States)

    Motes, Keith R.; Dowling, Jonathan P.; Gilchrist, Alexei; Rohde, Peter P.

    2015-11-01

    It was recently shown by Motes, Gilchrist, Dowling, and Rohde [Phys. Rev. Lett. 113, 120501 (2014), 10.1103/PhysRevLett.113.120501] that a time-bin encoded fiber-loop architecture can implement an arbitrary passive linear optics transformation. This was shown in the case of an ideal scheme whereby the architecture has no sources of error. In any realistic implementation, however, physical errors are present, which corrupt the output of the transformation. We investigate the dominant sources of error in this architecture—loss and mode mismatch—and consider how it affects the BosonSampling protocol, a key application for passive linear optics. For our loss analysis we consider two major components that contribute to loss—fiber and switches—and calculate how this affects the success probability and fidelity of the device. Interestingly, we find that errors due to loss are not uniform (unique to time-bin encoding), which asymmetrically biases the implemented unitary. Thus loss necessarily limits the class of unitaries that may be implemented, and therefore future implementations must prioritize minimizing loss rates if arbitrary unitaries are to be implemented. Our formalism for mode mismatch is generalized to account for various phenomenon that may cause mode mismatch, but we focus on two—errors in fiber-loop lengths and time jitter of the photon source. These results provide a guideline for how well future experimental implementations might perform in light of these error mechanisms.

  14. Sub-fs electron bunch generation with sub-10-fs bunch arrival-time jitter via bunch slicing in a magnetic chicane

    Directory of Open Access Journals (Sweden)

    J. Zhu

    2016-05-01

    Full Text Available The generation of ultrashort electron bunches with ultrasmall bunch arrival-time jitter is of vital importance for laser-plasma wakefield acceleration with external injection. We study the production of 100-MeV electron bunches with bunch durations of subfemtosecond (fs and bunch arrival-time jitters of less than 10 fs, in an S-band photoinjector by using a weak magnetic chicane with a slit collimator. The beam dynamics inside the chicane is simulated by using two codes with different self-force models. The first code separates the self-force into a three-dimensional (3D quasistatic space-charge model and a one-dimensional coherent synchrotron radiation (CSR model, while the other one starts from the first principle with a so-called 3D sub-bunch method. The simulations indicate that the CSR effect dominates the horizontal emittance growth and the 1D CSR model underestimates the final bunch duration and emittance because of the very large transverse-to-longitudinal aspect ratio of the sub-fs bunch. Particularly, the CSR effect is also strongly affected by the vertical bunch size. Due to the coupling between the horizontal and longitudinal phase spaces, the bunch duration at the entrance of the last dipole magnet of the chicane is still significantly longer than that at the exit of the chicane, which considerably mitigates the impact of space charge and CSR effects on the beam quality. Exploiting this effect, a bunch charge of up to 4.8 pC in a sub-fs bunch could be simulated. In addition, we analytically and numerically investigate the impact of different jitter sources on the bunch arrival-time jitter downstream of the chicane, and define the tolerance budgets assuming realistic values of the stability of the linac for different bunch charges and compression schemes.

    We design a low-timing-jitter, repetition-rate-tunable, stretched-pulse passively mode-locked fiber laser by using a nonlinear amplifying loop mirror (NALM), a semiconductor saturable absorber mirror (SESAM), and a tunable optical delay line in the laser configuration. Low-timing-jitter optical pulses are stably produced when a SESAM and a 0.16 m dispersion compensation fiber are employed in the laser cavity. By inserting a tunable optical delay line between NALM and SESAM, the variable repetition-rate operation of a self-starting, passively mode-locked fiber laser is successfully demonstrated over a range from 49.65 to 50.47 MHz. The experimental results show that the newly designed fiber laser can maintain the mode locking at the pumping power of 160 mW to stably generate periodic optical pulses with width less than 170 fs and timing jitter lower than 75 fs in the 1.55 µm wavelength region, when the fundamental repetition rate of the laser is continuously tuned between 49.65 and 50.47 MHz. Moreover, this fiber laser has a feature of turn-key operation with high repeatability of its fundamental repetition rate in practice

    Full Text Available The EU is facing a multi-faceted, existential, crisis; it is an economic and social crisis in some countries, a political and cultural crisis all over the EU and a geopolitical crisis at the international level. National governments have taken the lead in the crisis management of the EU: the European Council has become the dominant institution and the intergovernmental method has come back into fashion. But intergovernmentalism has failed: since 2008 the crisis keeps getting worse. Intergovernmentalism is leading towards the EU’s disintegration. Among many voices to save the EU, it is interesting that the supranational institutions, and particularly the Parliament, are taking on themselves the responsibility to take the initiative and indicate a possible way forward for the Union.

    This paper introduces a supercontinuum (SC) laser source emitting from 400 nm to beyond 1750 nm, with adjustable pulse repetition rate (from 250 kHz to 1 MHz) and duration (from ~200 ps to ~2 ns). This device makes use of an internally-modulated 1.06 μm semiconductor laser diode as pump source. The output radiation is then amplified through a preamplifier (based on single-mode Yb-doped fibres) followed by a booster (based on a double-clad Yb-doped fibre). The double-clad fibre output is then spliced to an air-silica microstructured optical fibre (MOF). The small core diameter of the double-clad fibre allows reducing the splice loss. The strongly nonlinear propagation regime in the MOF leads to the generation of a SC extending from the violet to the nearinfrared wavelengths. On the Stokes side of the 1.06 μm pump line, i.e., in the anomalous dispersion regime, the spectrum is composed of an incoherent distribution of quasi-solitonic components. Therefore, the SC source is characterised by a low coherence length, which can be tuned by simply modifying pulse duration, that is closely related to the number of quasi-solitonic components brought into play. Finally, the internal modulation of the laser diode permits to achieve excellent temporal stability, both in terms of average power and pulse-to-pulse period.

    151 Eu nuclear resonant inelastic scattering of Eu 3 Pd 20 Ge 6 . The Eu partial phonon density of states (DOS) in Eu 3 Pd 20 Ge 6 are investigated using 151 Eu nuclear resonance inelastic scattering (NRIS). 151 Eu NRIS was carried out at BL09XU of SPring-8. Significant temperature dependence was found in the partial phonon DOS. Judging from the valence change at the Eu 4a site and the comparison with the ab initio calculation of Eu 3 Pd 20 Ge 6 , the change of the Eu DOS is caused by the electronic states. On the other hand, significant acoustic contribution was found even at the guest site of the Eu ones. In addition, slower average velocity than transverse sound velocity was obtained by Eu partial phonon DOS. Considering that heat is carried by the acoustic phonon in materials, the present results demonstrate that the moderate thermal insulation in Eu 3 Pd 20 Ge 6 is connected with the observation of slow average sound velocity at the Eu sites.

    We study the valence band of Eu-intercalated C60 by synchrotron radiation photoelectron spectroscopy to un-derstand the ferromagnetism (FM) and the giant magnetoresistance (GMR) of Eu6C60. The results reveal the semiconducting property and the remarkable 5d6s-π hybridization. Eu-C60 bonding has both ionic and covalent contributions. No more than half the 5d6s electrons transfer from Eu to the LUMO derived band of C60, and the LUMO+1 derived band is not filled. The remaining valence electrons of Eu, together with some π (LUMO, HOMO and HOMO-1) electrons, constitute the covalent bond. The electronic structure implies that the magnetic coupling in Eu6C60 should be through the intra-atomic f-sd exchange and the medium of the π electrons. The possibility of the GMR being tunnelling magnetoresistance is ruled out.

  7. The Influence of Migration Crisis in Europe on EU-Turkey Relations

    Pavel P. Timofeyev

    2016-01-01

    Full Text Available The paper examines the impact of the migration crisis in the EU on the European Union's relations with Turkey. It is shown that for a number of reasons, including a result of EU actions taken from 2011 to 2015, EU has experienced an influx of migrants on a number of routes from the Western to the Eastern Mediterranean. The largest of them fell on Turkey, which has tried to use this factor to exert pressure on the EU in order to obtain economic and political preferences. The author examines the development of the EU migration policy in the context of the crisis, its trying to bring Turkey to cooperate and difficult negotiations, which took place at the summits of the EU-Turkey at the end of 2015. There have been disagreements among the EU countries, and the time factor, which Turkey took advantage of, advancing conditions for the closure of borders to Europe for migrants. Facing the influx of migrants the EU had to agree with a number of conditions, though not with all. The author shows that the agreement reached by the country in March 2016 is not universal, and a number of issues important to the resolution of the crisis, are waiting to be decided upon. However, according to the author, the development of the current crisis can lead both to the reform of the migration and border policy within the EU, and to restarting relations with Turkey. Though guessing on possibilities on Turkey's entry to the EU in the near future is still premature.

  12. Lead poisoning

    Beijers, J A

    1952-01-01

    Three cases of acute lead poisoning of cattle herds via ingestion are reported, and reference is made to several other incidents of lead in both humans and animals. The quantity of lead which was found in the livers of the dead cows varied from 6.5 to 19 mg/kg, while 1160 mg/kg of lead in the liver was found for a young cow which was poisoned experimentally with 5 gms of lead acetate per day; hence, there appears to be great variability in the amounts deposited that can lead to intoxication and death. No evidence was found for a lead seam around the teeth, prophyrinuria, or basophil granules in the erythrocytes during acute or chronic lead poisoning of cattle or horses examined. Reference is made to attempts of finding the boundary line between increased lead absorption and lead intoxication in humans, and an examination of 60 laborers in an offset-printing office containing a great deal of inhalable lead (0.16 to 1.9 mg/cu m air) is reviewed. Physical deviation, basophylic granulation of erythrocytes, increased lead content of the urine, and porphyrinuria only indicate an increased absorption of lead; the use of the term intoxication is justified if, in addition, there are complaints of lack of appetite, constipation, fatigue, abdominal pain, and emaciation.

    The interaction of a multi-petawatt, pancake-shaped laser pulse with an unmagnetized plasma is studied analytically and numerically in a regime with ultrarelativistic electron jitter velocities, in which the plasma electrons are almost completely expelled from the pulse region. The study is applied to a laser wakefield acceleration scheme with specifications that may be available in the next generation of Ti:Sa lasers and with the use of recently developed pulse compression techniques. A set of novel nonlinear equations is derived using a three-timescale description, with an intermediate timescale associated with the nonlinear phase of the electromagnetic wave and with the spatial bending of its wave front. They describe, on an equal footing, both the strong and the moderate laser intensity regimes, pertinent to the core and to the edges of the pulse. These have fundamentally different dispersive properties since in the core the electrons are almost completely expelled by a very strong ponderomotive force, and the electromagnetic wave packet is imbedded in a vacuum channel, thus having (almost) linear properties. Conversely, at the pulse edges, the laser amplitude is smaller, and the wave is weakly nonlinear and dispersive. New nonlinear terms in the wave equation, introduced by the nonlinear phase, describe without the violation of imposed scaling laws a smooth transition to a nondispersive electromagnetic wave at very large intensities and a simultaneous saturation of the (initially cubic) nonlocal nonlinearity. The temporal evolution of the laser pulse is studied both analytically and by numerically solving the model equations in a two-dimensional geometry, with the spot diameter presently used in some laser acceleration experiments. The most stable initial pulse length is estimated to exceed ≳1.5–2 μm. Moderate stretching of the pulse in the direction of propagation is observed, followed by the development of a vacuum channel and of a very large

  15. Renewable energies in the EU

    International Nuclear Information System (INIS)

    Heller, W.

    2008-01-01

    On January 23, 2008, the European Commission presented proposals in the form of a directive in an effort to give more specific shape to the objective adopted in the spring, i.e. to increase to 20% by 2020 the share of renewable energies in energy consumption in the Community. The proposal was to include legally binding goals for the overall share of renewable energy sources and the share of biofuels in the transport sector. The proposed directive on 'promoting the use of energy from renewable sources' calls upon each member state to ensure that its share of energy from renewable sources in the total energy consumption in 2020 at least corresponds to the target mentioned in Annex I Part A. In addition to the targets, the EU Commission charted a tentative course towards a minimum increase in the share of renewable energies in the period between 2011 and 2020. Finally, the member states are obliged to adopt national action plans. Unfortunately, the EU is missing an important target in its proposed directive: It should establish a framework for harmonized conditions promoting the use of renewable energies. One aspect to be welcomed is the introduction of a system of certificates of origin. It represents the entry, in principle, into a trading system with certificates of origin. The Green Package incorporates a wealth of new approaches. They will have to be tested and, if necessary, supplemented. Something else is evident, however: The directive established the foundations of a vast number of new regulations and red tape. (orig.)

  17. Policy options for carbon taxation in the EU

    2010-06-01

    Even though the EU clearly leads the global fight against climate change and despite the additional reduction in emissions due to the global crisis and European recession, the ambitious objectives flagged in the '20-20-20 by 2020' strategy and 'climate-energy package' are probably out of reach if a more resolute and consistent policy of carbon taxation is not rapidly put in place. First, the EU is not as 'virtuous' as it may seem, and shows signs of a 'fatigue' in mitigating climate change; this is explained by the weak incentive structure of current climate institutions, due to both narrow coverage and insufficient stringency of the European 'Emission Trading Scheme' (ETS) - the European 'carbon market'-, and to excessive reliance on emission standards combined with weak energy taxation. Fears of losing competitiveness are a major argument against imposing a higher carbon price on industries, feeding tax competition both within the EU and vis-a-vis the rest of the world. Though not fully satisfactory, the Commission's recent proposal (a revision of the 2003 energy taxation directive introducing floors on national excises based on carbon content) would help solving the intra-EU conundrum. Alternatively, an extension of the EU ETS to households and the transport sector via the 'upstream' inclusion of fossil fuel dealers would also be a feasible solution. In order to answer the 'carbon leakage' argument and to send appropriate price signals to European consumers on extra-EU imports, a border adjustment mechanism - carbon levy or inclusion of importers into the EU ETS - is also necessary. Ultimately though, in order to make sure that economic agents face a uniform carbon price, a generalized carbon tax, in the form of a European 'Carbon Added Tax' (ECAT), would be the most effective instrument in the fight against climate change, as well as the pillar of a thorough tax

  4. EU policy options for climate and energy beyond 2020

    In 2009, the EU climate and energy package with targets for 2020 (the so-called 20-20-20 targets) were formulated. For the period after 2020, however, there are no legally binding targets at the EU level, except for a decreasing ETS cap which will not be sufficient in light of the ambition for 2050. This leads to uncertainty for market players, as project lead times are long and high upfront investments need to deliver returns well beyond 2020. In its Green Paper on a 2030 framework for climate and energy policies, the European Commission recognised the need for clarity regarding the post-2020 policy framework. Currently under discussion is whether the approach for 2020 should be continued towards 2030 in the form of three more stringent targets or that other approaches would be more appropriate. Within this context, the Dutch Government asked PBL Netherlands Environmental Assessment Agency and Ecofys for advice. PBL and Ecofys have subsequently analysed possible options for an EU policy framework for 2030 that will steer towards a low-carbon economy by 2050 in a cost-effective way.

  5. A single gene (Eu4) encodes the tissue-ubiquitous urease of soybean.

    1994-02-01

    We sought to determine the genetic basis of expression of the ubiquitous (metabolic) urease of soybean. This isozyme is termed the metabolic urease because its loss, in eu4/eu4 mutants, leads to accumulation of urea, whereas loss of the embryo-specific urease isozyme does not. The eu4 lesion eliminated the expression of the ubiquitous urease in vegetative and embryonic tissues. RFLP analysis placed urease clone LC4 near, or within, the Eu4 locus. Sequence comparison of urease proteins (ubiquitous and embryo-specific) and clones (LC4 and LS1) indicated that LC4 and LS1 encode ubiquitous and embryo-specific ureases, respectively. That LC4 is transcribed into poly(A)+ RNA in all tissues was indicated by the amplification of its transcript by an LC4-specific PCR primer. (The LS1-specific primer, on the other hand, amplified poly(A)+ RNA only from developing embryos expressing the embryo-specific urease.) These observations are consistent with Eu4 being the ubiquitous urease structural gene contained in the LC4 clone. In agreement with this notion, the mutant phenotype of eu4/eu4 callus was partially corrected by the LC4 urease gene introduced by particle bombardment.

    Graphical abstract: We have synthesized Eu 2+ doped and Eu 2+ /Mn 2+ co-doped Ca 3 (PO 4 ) 2 phosphors. The emitting color varies from blue to green with increasing of Eu 2+ content for the Eu 2+ -doped phosphor, and the quantum yield of the 0.05Eu 2+ : Ca 2.95 (PO 4 ) 2 sample reaches 56.7%. Interestingly, Mn 2+ co-doping into Eu 2+ : Ca 3 (PO 4 ) 2 leads to its phase transition from orthorhombic to rhombohedral, and subsequently generates tunable multi-color luminescence from green to red via Eu 2+ → Mn 2+ energy transfer. - Highlights: • A series of novel Eu 2+ : Ca 3 (PO 4 ) 2 phosphors were successfully synthesized. • Phase transition of Ca 3 (PO 4 ) 2 from orthorhombic to rhombohedral occurred when Mn 2+ ions were doped. • The phosphors exhibited tunable multi-color luminescence. • The quantum yield of 0.05Eu 2+ : Ca 2.95 (PO 4 ) 2 phosphor can reach 56.7%. • The analyses of phosphors were carried out by many measurements. - Abstract: Intense blue-green-emitting Eu 2+ : Ca 3 (PO 4 ) 2 and tunable multicolor-emitting Eu 2+ /Mn 2+ : Ca 3 (PO 4 ) 2 phosphors are prepared via a solid-state reaction route. Eu 2+ -doped orthorhombic Ca 3 (PO 4 ) 2 phosphor exhibits a broad emission band in the wavelength range of 400–700 nm with a maximum quantum yield of 56.7%, and the emission peak red-shifts gradually from 479 to 520 nm with increase of Eu 2+ doping content. Broad excitation spectrum (250–420 nm) of Eu 2+ : Ca 3 (PO 4 ) 2 matches well with the near-ultraviolet LED chip, indicating its potential applications as tri-color phosphors in white LEDs. Interestingly, Mn 2+ co-doping into Eu 2+ : Ca 3 (PO 4 ) 2 leads to its phase transition from orthorhombic to rhombohedral, and subsequently generates tunable multi-color luminescence from green to red via Eu 2+ → Mn 2+ energy transfer, under 365 nm UV lamp excitation

    The European Union's increasing reliance on imports from third countries is reason for unsettling concern. It is anticipated that by 2030, assuming a continuation of the recent trend, more than 70 per cent of the EU's energy consumption has to be imported. Notwithstanding such anticipation, European regulation addressing the external dimension of energy policy remained far and few between. In practise it is the individual countries being leading actors on the foreign energy relations stage exercising their own respective foreign policies. To cope with these threats to the EU foreign energy policy, the European Commission issued its long anticipated Communication on security of energy supply and international cooperation proposing concrete instruments on how energy foreign relations should be addressed in the future.

    Full Text Available This paper examines the determinants of the intra-EU direct investment (IDI into the New Member States (NMS using a panel dataset of bilateral capital flows for the period 1993-2013. It is found out by using a simple gravity model that EU membership is the most important determinant. Unlike previous studies including non-EU countries, the distance is insignificant, which is caused by proximity of these countries to one another. A separate analysis focused on subgroups of accession countries gives some evidence that even when size of their economy, distance, institutional quality and EU accession are taken into account, Central European countries receive more IDI than the Baltic and the Balkan states. On the contrary to that, the analysis restricted to the Balkan countries which have joined the EU shows the inexistence of a negative Balkans effect in attracting foreign investment. This finding is relevant because previous studies demonstrate a persistent negative Balkans effect for non-EU Balkan countries and suggests a crucial impact of the EU accession in determining the intra-EU capital flows.

  3. The paradox of EU enlargement and member states' policies: Dilemmas and challenges: The case of Portugal

    Directory of Open Access Journals (Sweden)

    Neves Santos Miguel

    2016-01-01

    Full Text Available The paper addresses the issue of EU enlargement with its dual nature: of an intra-EU process, related to the consolidation of a democratic-peace based on collective security, and an external process, involving EU foreign policy and impact on relations with other major global players. Although enlargement is a multidimensional process that combines different perspectives - candidate countries' enlargement politics, member states' politics/policy, EU enlargement politics and external global impact - the paper focuses on Member States policies towards enlargement by looking at the case of Portugal, in particular in relation with the Big Bang Eastern enlargement, and aims at explaining the paradox of Portugal's strong political support to enlargement while it was one of the main potential losers in terms of economic interests. A 'foreign policy analysis' framework is adopted in order to understand the process of decision-making and the interaction between the domestic and the EU levels. The argument put forward is that an exclusive constructivist approach does not provide a satisfactory explanation, as there was also rationalist-interest logic at play. The Portuguese policy towards enlargement was determined not only by the 'solidaritysimilarity' logic, dominant in the formal political discourse but also by the consideration of long-term interests in the EU related to the preservation of the strategic alliance with Germany. The overall systemic impact of enlargement tends to weaken the EU as it presents a major paradox functioning as a double-edged sword. While it has a positive impact by contributing to the enhancement of the EU international profile as it grows in size raising expectations about its potential global role, it also leads to greater heterogeneity, undermining the EU cohesion and its ability to act together with a single voice becoming a robust global player, thus frustrating the expectations raised in the first place.

    Bodunov, E.N.; Lebedev, V.P.; Malyshev, V.A.; Przheuskij, A.K.

    1989-01-01

    Experimental study of concentrational depolarization luminescence (CDL) of phosphate and germanate glasses, containing Eu 3+ ions, has been carried out. On the basis of three-body self-consistent approximation the theory of CDL is conceived, which takes into account Eu-Eu interaction of higher multipolarities. By comparing the theory with the experiment energy transfer radii for Eu-Eu dipole-dipole, dipole-quadrupole and quadrupole-quadrupole interactions are determined. The attempt to discriminate Eu-Eu interaction types in the studied range of Eu 3+ ion concentration change has failed owing to law accuracy of luminescence emittance anisotropy measurement

  8. EU, Eastern Europe and Values Imperialism

    Directory of Open Access Journals (Sweden)

    Stephen White

    2014-01-01

    Full Text Available This paper proposes an idea of'values imperialism'as a helpful way of conceptualising the relationship between the EU and the states that came within its sphere of influence after the end of the Cold War, particularly its 'neighbours' in Eastern Europe. Values imperialism places its emphasis on the 'superstructure', including norms, laws and social practices. EU larger objective was that the assumptions about government and ownership that were favoured by the dominant powers (EU and the West in the broad term should be absorbed and recapitulated by those countries that were subordinate. The broad framework ofsubordination was established by the Partnership and Cooperation Agreements that began to be concluded from 1994 onwards. Patterns of'values imperialism'could also be discovered in the EU Common Strategies on Russia and Ukraine that were adopted in 1999. Article also points out several cases when the EU intervened directly in the domestic affairs of the Eastern Europe countries in a manner that was not always compatible with the provisions on state sovereignty: a 'European Instrument for Democracy and Human Rights', launched in 2006, interventions ofEU representatives in the work of local courts and organisation of exit polls, which could be used to discredit the official election results and in this way to undermine the position of local governments. Finally, the author concludes that the EU used 'values imperialism'practices in order to extend its influence, particularly in the Eastern Europe.

  9. Coordinating the Uncoordinated: The EU Forest Strategy

    2018-03-01

    Full Text Available The second European Union (EU Forest Strategy responds to new challenges facing both forests and the forest-based sector which highlights the EU’s need for a policy framework ensuring coordination and coherence of forest-related policies. The objective of the present article is to analyse whether the new Strategy contributes towards horizontal policy coherence of EU forest-related policies, given its shared and exclusive competences. This is achieved by comparing European Commission and forest industry policy priorities as articulated in the Strategy and through research carried out for the recent Cumulative Cost Assessment (CCA of forest-based industries. Results from the comparative analysis demonstrate that the Strategy does not address many EU policies and policy instruments that affect the whole forest value chain and that it clearly omits existing EU policy instrument objectives that entail significant costs for the forest-based industry. It is therefore argued that without coordinating collective EU goals and gathering strong political support, it is at best extremely difficult or at worst impossible, to achieve coherence for EU forest-related policies across the whole forest value chain. Improving coherence of Union forest-related policies will require the Strategy to address more policy areas and instruments, including clearly defined parameters of what constitutes an EU forest-related policy. These pressing needs reach beyond what the Strategy presently sets out to achieve.

  10. IMPACTS OF CLIMATE CHANGE ON EU AGRICULTURE

    2013-09-01

    Full Text Available The current paper investigates the medium term economic impact of climate changes on the EU agriculture. The yield change data under climate change scenarios are taken from the BIOMA (Biophysical Models Application simulation environment. We employ CAPRI modelling framework to identify the EU aggregate economic effects as well as regional impacts. We take into account supply and market price adjustments of the EU agricultural sector as well as technical adaptation of crops to climate change. Overall results indicate an increase in yields and production level in the EU agricultural sector due to the climate change. In general, there are relatively small effects at the EU aggregate. For example, the value of land use and welfare change by approximately between -2% and 0.2%. However, there is a stronger impact at regional level with some stronger effects prevailing particularly in the Central and Northern EU and smaller impacts are observed in Southern Europe. Regional impacts of climate change vary by a factor higher up to 10 relative to the aggregate EU impacts. The price adjustments reduce the response of agricultural sector to climate change in particular with respect to production and income changes. The technical adaption of crops to climate change may result in a change production and land use by a factor between 1.4 and 6 relative to no-adaptation situation.

  11. Enlarging the EU's internal energy market: Why would third countries accept EU rule export?

    International Nuclear Information System (INIS)

    Prange-Gstoehl, Heiko

    2009-01-01

    Why would countries without a membership perspective seek integration into the EU's internal energy market? One major element of the EU's external energy policy is the export of EU energy norms and regulations to neighbourhood countries and beyond. A core legal instrument the EU uses in this context is the Energy Community Treaty (ECT). The ECT goes both geographically and regarding its depth significantly beyond neighbourhood or association policies, addressing potentially also countries in the 'far neighbourhood' and aiming at the creation of a Single Market for energy with these countries. While, however, EU candidate countries are obliged to adopt the 'acquis' before accessing the EU and therefore comply to EU rules already before they enter the Club, I argue that countries with no or only a vague membership perspective - i.e. countries where the EU cannot apply the 'conditionality' - approach (e.g., ENP countries)-aim at deeper integration with the EU because they are either eager to demonstrate their capability and potential to become part of the Club, they seek greater independence from a regional hegemon or they envisage significant economic gains as common norms, rules and standards are likely to increase economic exchange with the EU.

  12. Challenges of public procurement in EU funded projects

    Directory of Open Access Journals (Sweden)

    Marko Šostar

    2017-01-01

    Full Text Available Membership in the European Union implies adjustment of EU projects to the rules of Structural Funds, but also adoption of legal regulations, thus influencing the process of implementation of the public procurement in EU funded projects. Each successful applicant who expressed the need for procurement of goods, services and works of a certain value, must respect the principles of public procurement. Irregularities in the procurement process can lead to the failure of returning the EU funds even several years after the end of the project. Therefore, the knowledge and proper implementation of public procurement is the main precondition for the correct implementation of each project. In order to obtain information about the current absorption capacity of the public procurement liable parties, and to identify key obstacles that stakeholders face in procurement procedures, the research was conducted by surveying 30 entities that are subject of public procurement in Croatia. Research results imply the poor quality of public procurement in the implemented projects, which often results in financial corrections, disapproving project reports, etc.

    McBlane, James W

    2015-09-01

    This article addresses regulation of cell therapies in the European Union (EU), covering cell sourcing and applications for clinical trials and marketing authorisation applications. Regulatory oversight of cell sourcing and review of applications for clinical trials with cell therapies are handled at national level, that is, separately with each country making its own decisions. For clinical trials, this can lead to different decisions in different countries for the same trial. A regulation is soon to come into force that will address this and introduce a more efficient clinical trial application process. However, at the marketing authorisation stage, the process is pan-national: the Committee for Human Medicinal Products (CHMP) is responsible for giving the final scientific opinion on all EU marketing authorisation applications for cell therapies: favourable scientific opinions are passed to the European Commission (EC) for further consultation and, if successful, grant of a marketing authorisation valid in all 28 EU countries. In its review of applications for marketing authorisations (MAAs) for cell therapies, the CHMP is obliged to consult the Committee for Advanced Therapies (CAT), who conduct detailed scientific assessments of these applications, with assessment by staff from national regulatory authorities and specialist advisors to the regulators.

    1999-01-01

    The model evaluation group (MEG) was launched in 1992 growing out of the Major Technological Hazards Programme with EU/DG XII. The goal of MEG was to improve the culture in which models were developed, particularly by encouraging voluntary model evaluation procedures based on a formalised and consensus protocol. The evaluation intended to assess the fitness-for-purpose of the models being used as a measure of the quality. The approach adopted was focused on developing a generic model evaluation protocol and subsequent targeting this onto specific areas of application. Five such developments have been initiated, on heavy gas dispersion, liquid pool fires, gas explosions, human factors and momentum fires. The quality of models is an important element when complying with the 'Seveso Directive' requiring that the safety reports submitted to the authorities comprise an assessment of the extent and severity of the consequences of identified major accidents. Further, the quality of models become important in the land use planning process, where the proximity of industrial sites to vulnerable areas may be critical.

    2014-04-01

    Full Text Available On average, EU countries allocate 6.4% of total public expenditure for the direct support of the public sector at all levels of education. In view of a more rational allocation of resources seriously diminished by the crisis there are made efforts to identify educational areas considered problematic in terms of accessing various education programs. This paper presents pre-school funding policies and policies to support families with preschool and school age children in the European Union through a comparative analysis of the focus group type. There are also presented concrete ways of achieving that family support such as tax cuts, family allowances or by taking into account certain factors in order to establish fees. In all countries where taxes are paid for pre-compulsory education (ISCED A there is a mechanism by which parental contributions can be adjusted according to the means available taking into account criteria such as family income, number of children, family status (children who live with one parent geographic area, etc.

  2. Detecting vocal fatigue in student singers using acoustic measures of mean fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio

    Sisakun, Siphan

    2000-12-01

    The purpose of this study is to explore the ability of four acoustic parameters, mean fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio, to detect vocal fatigue in student singers. The participants are 15 voice students, who perform two distinct tasks, data collection task and vocal fatiguing task. The data collection task includes the sustained vowel /a/, reading a standard passage, and self-rate on a vocal fatigue form. The vocal fatiguing task is the vocal practice of musical scores for a total of 45 minutes. The four acoustic parameters are extracted using the software EZVoicePlus. The data analyses are performed to answer eight research questions. The first four questions relate to correlations of the self-rating scale and each of the four parameters. The next four research questions relate to differences in the parameters over time using one-factor repeated measures analysis of variance (ANOVA). The result yields a proposed acoustic profile of vocal fatigue in student singers. This profile is characterized by increased fundamental frequency; slightly decreased jitter; slightly decreased shimmer; and slightly increased harmonics-to-noise ratio. The proposed profile requires further investigation.

    Yttrium aluminium garnet (YAG) doped with Eu 2+ and Eu 3+ ions is very interesting as a phosphor for conversion of light-emitting diode light for white light sources. The europium ion occupies the structural position of yttrium in yttrium aluminium garnet and has valence state Eu 3+ . Our sample was doped with Zr 4+ , which is why some of the europium ions had valence state Eu 2+ . As a rule, luminescence of Eu 3+ ions is observed in the orange and red range of spectrum. The luminescence of Eu 2+ in yttrium aluminum garnet is characterized by an intensive broad band with maximum of intensity at about 560 nm (green color). In this work, we studied the intensity and decay time dependences on europium concentration, and the influence of excitation power density on the cathodoluminescence of the sample. The most interesting result is the change of visible cathodoluminescence color in dependence on the density of the exciting power

    According to a new report by CEDIGAZ, the International Centre for Natural Gas Information, gas has lost its attractiveness against coal in the EU power sector. Its demand by the sector decreased by one third during the past three years and its prospects are very weak in this decade. The Association warns that un-profitability of combined cycle gas turbines (CCGTs) and the retirement of old coal plants due to stringent air regulation may lead to the closure of one third of the current fleet and poses a serious security of supply issue that has to be addressed urgently

    Uros Delevic

    2017-02-01

    Full Text Available This research challenges the contemporary view of economic policy makers in transition European economies that the EU integration process will lead to a greater inflow of Foreign Direct Investments (FDI, thereby increasing living standards. With the Brexit referendum, the integration of the EU has been threatened by a distressing existential question: is EU membership valuable for transition countries if even developed countries (like the UK vote to leave or decided not to align like Switzerland and Norway in the past? Our analysis considers the success of several countries in Eastern Europe in attracting and benefiting from FDI on their way to EU membership. Analyzing a 13-year panel data of 16 transition countries, we found no statistically significant positive association between FDI inflow and EU accession. We argue, that it is also important to consider the welfare for domestic economies that can emerge from those investments. We illustrate this through the case study of a successful combination of institutional development and local content policies implementation accompanied by sufficient FDI inflows in a non-EU country - Kazakhstan.

  14. Synthesis and tunable luminescent properties of Eu-doped Ca2NaSiO4F – Coexistence of the Eu2+ and Eu3+ centers

    Directory of Open Access Journals (Sweden)

    Mubiao Xie

    Full Text Available Novel phosphors Ca2NaSiO4F:Eu were synthesized successfully by the conventional solid-state method in CO atmosphere, and their spectroscopic properties in UV−vis region were investigated. The photoluminescence properties show that Eu3+ ions were partially reduced to Eu2+ in Ca2NaSiO4F. As a result of radiation and re-absorption energy transfer from Eu2+ to Eu3+, both Eu2+ bluish-green emission at around 520 nm and Eu3+ red emission are observed in the emission spectra under the n-UV light excitation. Furthermore, the ratio between Eu2+ and Eu3+ emissions varies with increasing content of overall Eu. Because relative intensity of the red component from Eu3+ became systematically stronger, white light emission can be realized by combining the emission of Eu2+ and Eu3+ in a single host lattice under n-UV light excitation. These results indicate that the Ca2NaSiO4F:Eu phosphors have potential applications as a n-UV convertible phosphor for light-emitting diodes.

    SrF 2 :Eu nanophosphors were successfully synthesized by the hydrothermal method. The structure of the nanophosphors was investigated with x-ray diffraction. The average crystallite size calculated using the Scherrer equation was in the range of 7.0 nm. The photoluminescence of Eu doped as-prepared SrF 2 nanophosphors were studied using different excitation sources. The samples showed emission from both the Eu oxidation states, Eu 2+ and Eu 3+ . At low Eu concentrations the emission from Eu 2+ centered at 416 nm was more dominant. While the narrow band of Eu 3+ emission intensity increased with an increase in the Eu concentration. High resolution x-ray photoelectron spectroscopy results indicated that the Eu was indeed in both Eu 2+ and Eu 3+ valance states. The presence of Eu 2+ and Eu 3+ in the system largely enhanced the response of the Eu 3+ under ultraviolet excitation. The time of flight-secondary ion mass spectrometry results suggested that the energy transfer between two ions was likely to occur. The relative photoluminescence intensity of the Eu 2+ rapidly decreased with an increasing laser beam irradiating time. This result would make the current Eu 2+ doped SrF 2 samples unsuitable candidates for several applications, such as white light-emitting diodes and wavelength conversion films for silicon photovoltaic cells. - Highlights: • SrF 2 : Eu nanophosphors were successfully synthesised (hydrothermal technique). • PL and XPS results showed enhanced absorption response of Eu 3+ UV excitation. • Eu concentrations more than 5 mol% improved fluorescence emission. • TOF-SIMS results suggested that the energy transfer from Eu 2+ to Eu 3+ is dominant

    Lead (Pb) is a naturally occurring metallic element; trace concentrations are found in all environmental media and in all living things. However, certain human activities, especially base metal mining and smelting; combustion of leaded gasoline; the use of Pb in hunting, target shooting, and recreational angling; the use of Pb-based paints; and the uncontrolled disposal of Pb-containing products such as old vehicle batteries and electronic devices have resulted in increased environmental levels of Pb, and have created risks for Pb exposure and toxicity in invertebrates, fish, and wildlife in some ecosystems.

    The EuSe nanoparticles were prepared by the thermal reduction of Europium nitrate with new organic selenium compound, tetraphenylphosphonium diphenylphosphinediselenide (PPh 4 )(Se 2 P(C 6 H 5 ) 2 ), for the first time. EuSe nanoparticles were identified by the X-ray diffraction (XRD), the transmission electron microscope (TEM) and the energy dispersive X-ray spectroscopy (EDX) measurements. The average size of the EuSe nanoparticles was found to be 19 nm. The energy gap in EuSe nanoparticles of 19 nm was estimated by edge of absorption band, giving the energy gap of 1.86 eV

    CsI:Eu{sup 2+} needle crystal layers were produced by Physical Vapour Deposition (PVD). The luminescence properties were studied before and after thermal anneal. It was shown by Electron Paramagnetic Resonance (EPR) that annealing produces Eu{sup 2+} monomer centres, probably starting from Eu clusters in the needle crystalline layers. These centres seem structurally very similar to the Eu{sup 2+} monomer centres in annealed CsBr:Eu{sup 2+} needle layers. They give rise to a narrow luminescence band peaking at about 450 nm (2.76 eV) at room temperature, both under X-ray and UV excitation. The luminescence intensity of as-deposited layers is low. Annealing enhances photo- and radioluminescence on average by a factor of 1.5–3. Surprisingly, further sensitization of radioluminescence with a factor of up to 7 is possible by exposing the annealed needle layers to X-rays or UV, while in contrast, UV excited luminescence is slightly reduced. X-ray enhancement thus leads to a structured scintillator with a conversion efficiency of about 42,000 photons/MeV upon X-ray excitation. A similar radioluminescence enhancement is observed for annealed CsI:Eu{sup 2+} fine powder, but not for large single crystals or conglomerated polycrystals. The measurements and observations are consistent with Eu{sup 2+} monomer centres stabilized by water molecules. These molecules are incorporated via annealing, and that this happens when the morphology is such that water can diffuse throughout the volume of the crystals. The presence of stabilized Eu{sup 2+} monomers is necessary to enhance radioluminescence by X-ray exposure. A mechanism is proposed for the phenomenon.

    The interplay of magnetism with superconductivity is a fascinating, highly debated field of research and many questions still remain unsolved. Members of the EuFe{sub 2}As{sub 2} family are a perfectly suited playground for investigations concerning this topic, due to the peculiarity of strong local magnetism of the europium (T{sub N}∼ 20K), which is a unique feature among the 122 iron pnictides. Optical studies of the parent compound have already revealed that the spin density wave formation deviates from the other 122 pnictides. To get more insight into the superconducting properties of the EuFe{sub 2}As{sub 2} family we carried out an optical study on differently doped samples. We compare Eu(Fe{sub 1-x}Ir{sub x}){sub 2}As{sub 2} where electron doping takes place directly in the conducting iron layer, with EuFe{sub 2}(As{sub 1-x}P{sub x}){sub 2} which corresponds to isovalent substitution at atomic positions out of the Fe-plane. The influence of the Eu is furthermore investigated by placing data we obtained on Ba{sub 0.6}Eu{sub 0.4}(Fe{sub 1-x}Co{sub x}){sub 2}As{sub 2} in juxtaposition to the already highly investigated pure Ba analogue.

  9. Barriers to the EU Single Services Market

    2015-01-01

    Full Text Available The EU has the most developed liberalization mechanism in services trade within the framework of an economic bloc. The system of supranational institutions, which decisions are binding upon member states, contributes to a high level of liberalization of trade in services in the EU. However, the creation of a single market for services hasn't completed at all. The reasons are following: not all basic principles for single market are fully applied, and a service is a very specific object for international trade. Financial-economic crisis caused a new wave of protectionism in different countries, which has reflected in the preservation of old and the emergence of new barriers to trade in services within the EU. Integration of services in the Union is accompanied by important trade initiatives at the multilateral level. In the World Trade Organization EU countries negotiate a new agreement on trade in services, and offer provisions which providing transparency, deepening liberalization and investor protection for foreign investors in the market, will also complement and foster the Transatlantic Trade and Investment Partnership (TTIP EU - USA. Russia is only the fourth among most important partners of the EU in trade in services. At the same time the European Union remains a key Russian partner in trade in services and in goods. There is a considerable potential for growth in this sphere for both partners.

  10. EU GHG Emission Targets: 'Mind the gap'

    2012-06-01

    In Durban, the European Union has been able to overcome the traditional dividing lines between developed and developing countries, setting a 'road-map' for a post-Kyoto framework. This would see countries conclude an 'agreed outcome with legal force' on emissions targets by 2015. Was this a key goal or a partial success for EU climate diplomacy? The main concerns are that the second commitment period would only come into force by 2021, and that necessary carbon cuts are not be increased before 2020. The direct by-product for the EU victory has been the awakening of the debate about raising emissions reductions to 30%. In fact, as stated in the Low Carbon Road-map, the EU has adopted a target of cutting emissions by 20% to by 2020, and of moving to a 30% reduction target if the conditions are right. Is this finally the time for Europe to improve its performance, even if it means going it alone? The EU has always been a strong defender of the Kyoto Protocol under certain constraints, such as developing and emerging countries entering into the deal. But does the EU have all the right assets to fight for this? Where is Europe in achieving its 2020 goal? In essence, this paper provides an estimate of what EU emissions could be in 2020, and how they stand compared to Kyoto and 20% objective of the 2020 strategy. (author)

  14. Chinese investments in the EU

    2010-12-01

    Full Text Available China’s investments in the European Union are much lower than what you may expect given the economic size of both entities. These relatively low investments in Europe are a combination of priority and obstacles. The priority for investments is clearly in Asia, Africa and Latin America. This regional pattern is heavily influenced by the need to solve the resource shortage in the medium and long term. The investments in Europe and the United States are mostly market seeking investments. Research specifically focused on Chinese M&A abroad comes to the same conclusion. The success rate of Chinese M&A abroad is much lower than what we see with respect to American or European investments abroad. In this paper, we examine why Chinese firms are facing more difficulties in the European Union than in other regions. The paper focuses on Chinese M&A as proxy for total foreign direct investments abroad. By looking at the factors that have been documented as influencing the level of M&A abroad, it becomes clear that Chinese firms in Europe are hindered by many factors. For example, the trade between China and the EU is relatively low, the institutional quality is lower compared to the United States, there is less experience with respect to Europe and relatively many deals relate to State Owned Enterprises (SOE which makes the deal sensitive. So it is logical that Chinese investments are not very high in Europe. However, the research makes clear that the obstacles for Chinese investments in Europe are disappearing step by step. In that sense, we expect a strong increase of Chinese investments in Europe in the future.

    BaCl 2 :Eu 2+ microcrystals embedded in the NaCl host have been obtained in the NaCl–BaCl 2 (1 mol%)–EuCl 3 (0.02 mol%) crystalline system. The influence of the annealing conditions on the formation of such particles has been studied. In particular, long-term annealing (at 200 °S during 100 h) promotes the microcrystals formation in the NaCl–BaCl 2 –Eu crystalline system. The subsequent heat treatment (annealed at 600 °S during 72 h and quenched to room temperature) is shown to lead to the destruction of the majority of these particles. The luminescent-kinetic properties of BaCl 2 :Eu 2+ microcrystals have been studied upon the ultra-violet excitation by the synchrotron radiation. The X-ray excited luminescence has been measured in order to estimate the distribution of europium ions between microcrystals and the NaCl host. The excitation mechanisms of Eu 2+ ions in the NaCl–BaCl 2 –Eu crystalline system are discussed. - Highlights: ► The formation of BaCl 2 :Eu 2+ microcrystals of 1–100 μm size embedded in the NaCl host is revealed. ► Annealing at 600 °C leads to the destruction of significant number of embedded microcrystals. ► The luminescent parameters of microcrystals is similar to ones of single crystal analogs.

    We report the effect of replacing Cu by Pd in RCu 5 (R=Pr, Nd, Sm and Eu). The parent RCu 5 compounds crystallize in the hexagonal CaCu 5 -type structure. The hexagonal symmetry is retained in PrCu 4 Pd and EuCu 5-x Pd x (x=1 and 2) but the crystal structure changes to cubic AuBe 5 -type in PrCu 3 Pd 2 , NdCu 5-x Pd x (x=1 and 2) and SmCu 4 Pd. Substitution with Pd leads to lattice expansion and modifies the magnetic behavior. While PrCu 5 is known to be a van-Vleck paramagnet with a singlet ground state, PrCu 4 Pd and PrCu 3 Pd 2 show ferromagnetic-like behavior at low temperatures. SmCu 4 Pd orders ferromagnetically near 28 K in contrast to the antiferromagnetic nature of the parent SmCu 5 . The divalent nature of the Eu ions in EuCu 5 is retained in the ternary alloys, but the Curie temperature is reduced from 57 to 24.5 and 14.5 K in EuCu 4 Pd and EuCu 3 Pd 2 , respectively, inferred from the location of peak in the heat capacity of these two compounds. The magnetic hyperfine field at the Eu nucleus measured with 151 Eu Moessbauer spectroscopy in the ternary Eu-alloys is comparable to that in EuCu 5 . The magnetic behavior of NdCu 4 Pd is similar to that reported in NdCu 5 . The zero-field-cooled, low-field magnetization of NdCu 3 Pd 2 shows a region of diamagnetic behavior roughly between 21 and 4 K, but the field-cooled response is positive.

  4. Charge compensation mechanisms in favor of the incorporation of the Eu3+ ion into the ZnO host lattice

    Eu3+ doped phosphors with charge compensation are potential candidates of red emitting phosphors for lamp applications. Charge compensation improves the luminescence performance of the material. The charge compensation can most probably be achieved by three possible mechanisms: (a) two Zn2+ ions are replaced by one Eu3+ ions and one monovalent cation, 2Zn2+ →Eu3++ Li+, where Li+ is acting as a charge compensator; (b) the charge compensation is provided by a zinc vacancy (VZn) defects, 3Zn2+ → 2Eu3++ VZn, the subscript Zn denotes an ion in a normal zinc site in the lattice; (c) two Zn2+ ions are replaced by one Eu3+ ions with the presence of interstitial oxygen (Oi), 2Zn2+ → 2Eu3++ Oi. Electronic structures of the crystals corresponding to the three models are evaluated by the first-principles quantum mechanical calculations based on the density functional theory. It is found that the charge compensator defects make Eu3+ doping in ZnO energetically more favorable. They break the local symmetry around the Eu3+ ion and lead to deep states below the empty upper band, the conduction band that could facilitate intra-4f shell transitions, which can obviously improve the emission intensity of Eu3+-doped ZnO. Therefore, the effect of these defects on the host crystals electronic band states relative to the Eu3+ states is reported, since both electron transfer and electronically energy transfer processes enhance the performance of optoelectronic devices based on this material. These theoretical insights are helpful for designing rare-earth doped oxide materials with high photoluminescence (PL) performance.

    This paper seeks to explore some of the conditions under which energy policy could be formulated in and by the European Union (EU) over the next 40 years. The development of energy policy at the EU level is addressed from a wider historical perspective, taking into account a number of factors that influence both the EU project and its energy supply security. These factors include the EU's international orientation and cooperation; the EU 'economic community of law' paradigm; the EU's (failing?) external leadership role; the impact of the fall of the Berlin Wall; and Europe's talents for creativity and improvisation. These factors are discussed in somewhat greater depth in the context of the formulation of an all-EU energy policy. The global energy policy environment is briefly discussed, indicating that energy resources for the world are less at stake than their access. On this basis, a closer look is taken at the theoretical and practical aspects of using scenarios as a tool for energy policy-making. A few examples are presented, and it is argued that scenarios should basically be addressed on the basis of storylines. Storylines do require a set of specific parameters, and in this case the choice was made to use the various roles played by stakeholders for intervening in markets and in the world order. This choice is argued on the basis of the global interrelations that are currently influencing resource policies in general and energy in particular. Market efficiency, climate change, poverty issues, geopolitics and global coordination mechanisms are considered, leading to the two policy dimensions of 'nationalism' versus 'globalism' and 'heavy' versus 'light' government as the axes for the scenarios and storylines. This paper develops four storylines that are conceivable and inherently consistent. They are labelled with names that refer not only to their content, but also to the political and

    Hyperfine interactions in europium orthophosphate EuPO{sub 4} were investigated using {sup 151}Eu Mössbauer spectroscopy from 6 to 300 K. The value of the quadrupole splitting and the asymmetry parameter were refined and further substantiated by nuclear forward scattering data obtained at room temperature. The temperature dependence of the relative absorption was modeled with an Eu specific Debye temperature of 221(1) K. Eu partial lattice dynamics were probed by means of nuclear inelastic scattering and the mean force constant, the Lamb-Mössbauer factor, the internal energy, the vibrational entropy, the average phonon group velocity were calculated using the extracted density of phonon states. In general, Eu specific vibrations are characterized by rather small phonon energies and contribute strongly to the total entropy of the system. Although there is no classical Debye like behavior at low vibrational energies, the average phonon group velocity can be reasonably approximated using a linear fit.

    The article deals with indicators framework to monitor implementation of the main EU (European Union) directives and other policy documents targeting sustainable energy development. The main EU directives which have impact on sustainable energy development are directives promoting energy efficiency and use of renewable energy sources, directives implementing greenhouse gas mitigation and atmospheric pollution reduction policies and other policy documents and strategies targeting energy sector. Promotion of use of renewable energy sources and energy efficiency improvements are among priorities of EU energy policy because the use of renewable energy sources and energy efficiency improvements has positive impact on energy security and climate change mitigation. The framework of indicators can be developed to establish the main targets set by EU energy and environmental policies allowing to connect indicators via chain of mutual impacts and to define policies and measures necessary to achieve established targets based on assessment of their impact on the targeted indicators representing sustainable energy development aims. The article discusses the application of indicators framework for EU sustainable energy policy analysis and presents the case study of this policy tool application for Baltic States. The article also discusses the use of biomass in Baltic States and future considerations in this field.

    Full Text Available One of the most important phenomena of the last decade has been the convergence of the financial services industry, especially the capital and insurance markets. The convergence in the insurance industry was determined by the increased frequency and the severity of catastrophic risks, market inefficiency in the past, and the new technologies in IT and communications. These globally developments can be observed much better at EU level, one of the most integrated areas of the world, which aimed the convergence of financial market, including an important component such as insurance market. As part of the EU, Romania also aims to financial market convergence with the EU countries. The article offers an overview and an analysis of the insurance market in the EU and Romania. Through a wide series of indicators such as: the amount of insurance premiums, degree of penetration, number of employees or number of insurance companies, it will analyze the evolution of this market convergence, as per all EU countries and Romania. It will identify the stage in which the insurance market in Romania is, regarding the requirements of full integration. Finally, there will be identified factors encouraging and particularly those who are impediments to insurance market convergence in Romania.

    Full Text Available A specter is haunting Europe – the specter of separatism. Scotland, Catalonia, Flanders, South Tyrol – all these regions have separatist movements pursuing independence from their current National State. The breakup of an EU Member State no longer seems impossible. To date, it is unclear what impact this would have on the EU membership of the new entities (with consequences for the character of citizenship, voting rights in the council, number of MEPs etc. that emerge from the old States. The common rules of Public International Law governing the succession of States are insufficient in the case of a succession of States in the EU. Although the Treaties do not provide for such a situation and the past 60 years of European history offer only a few and not really persuasive precedents, the nature of the EU as a joint association of sovereign States (“Staatenverbund” demands a special approach: A separated State will neither be automatically excluded from the EU nor will it automatically become a new Member State.

    Full Text Available In this paper, the author intends to highlight the overall evolution of Romania's bilateral trade relations with EU in the period 2007-2015. On this background it is important to mention that the European Union (EU has been the main trade partner of Romania both the export and import throughout this period of post-accession. So, during the analyzed period, as can be observed from statistical data provided by INSSE it is obvious a general tendency of enhancing Romania's trade with EU. Furthermore, since 2007 EU has held a share of over 70% in total imports and exports of Romania. Also, relative to the evolution of Romania's trade balance in relation with EU, from statistical data presented in the paper, can be noticed that in the reference period it has known a general negative trend. There are also presented some positive progress of our country in issue of adjusting the trade balance deficit with EU. In these circumstances, can be proposed a range of macroeconomic measures formulated in direction of reducing the trade deficit, registered by our country in relation with EU. Another element of maximum visibility in this analyzed issues is represented by geographical orientation of Romanian exports and imports with EU countries. Starting from statistical data provided by INSSE through the prestigious official publication Romanian International Trade Yearbook, results clearly that in the whole of this reference period, Germany had the most significant share of over 20%, both export and import. Also during this period of post-accession, the attention of policy makers should focus on measures that will can lead to increase of Romania 's trade not only with Germany, Italy, France, Hungary etc. but also with other community partners whose share in Romania's total trade with EU was a insignificant along analysed period. Thus, in the current context and in perspective for Romania is imperative necessary the proliferation, intensification and

    A comparison is presented between Eu implanted and Eu in situ doped GaN thin films showing that two predominant Eu sites are optically active around 620 nm in both types of samples with below and above bandgap excitation. One of these sites, identified as a Ga substitutional site, is common to both types of Eu doped GaN samples despite the difference in the GaN film growth method and in the doping technique. High-resolution photoluminescence (PL) spectra under resonant excitation reveal that in all samples these two host-sensitized sites are in small amount compared to the majority of Eu ions which occupy isolated Ga substitutional sites and thus cannot be excited through the GaN host. The relative concentrations of the two predominant host-sensitized Eu sites are strongly affected by the annealing temperature for Eu implanted samples and by the group III element time opening in the molecular beam epitaxy growth. Red luminescence decay characteristics for the two Eu sites reveal different excitation paths. PL dynamics under above bandgap excitation indicate that Eu ions occupying a Ga substitutional site are either excited directly into the 5 D 0 level or into higher excited levels such as 5 D 1 , while Eu ions sitting in the other site are only directly excited into the 5 D 0 level. These differences are discussed in terms of the spectral overlap between the emission band of a nearby bound exciton and the absorption bands of Eu ions. The study of Eu doped GaN quantum dots reveals the existence of only one type of Eu site under above bandgap excitation, with Eu PL dynamics features similar to Eu ions in Ga substitutional sites

  6. The Impact of the Explosion of EU News on Voter Choice in the 2014 EU Elections

    Directory of Open Access Journals (Sweden)

    Jan Kleinnijenhuis

    2016-02-01

    Full Text Available The European elections in 2014 were the first to be held after a long period in which EU-related news was prominent in the media. They were held after years of daily news about the euro crisis and after months of news about the popular uprising in the Ukraine against president Yanukovych, who had refused to sign the association agreement with the EU. This could have invited political parties to overcome the usual problem of low salience of EU issues by strongly profiling themselves on EU issues. Turnout at the 2014 EU elections, however, remained low, hinting that parties were unable to convert the attention for European issues into enthusiasm for their party at the European elections. This paper asks how vote choice was influenced by party campaigning on EU related issues. A news effects analysis based on a content analysis of Dutch newspapers and television, and on a panel survey among Dutch voters revealed that EU issues functioned as wedge issues: the more strongly parties were associated in the news with the euro crisis and the Ukraine, the less they succeeded in mobilizing voters.

  7. Border tax adjustments and the EU-ETS. A quantitative assessment

    International Nuclear Information System (INIS)

    Manders, T.; Veenendaal, P.

    2008-10-01

    If the EU stands alone in adopting climate policy and imposes a strict emissions ceiling, competitiveness of EU energy-intensive sectors will be affected negatively. Relocation of EU energy-intensive firms to countries with a lax regime also leads to carbon leakage. However, when use is made of the opportunities of the Clean Development Mechanism these impacts are very modest. Border tax adjustments (BTAs) to 'level the playing field' between domestic and foreign producers may be considered to address the concerns about both competitiveness and carbon leakage. It is far from clear whether these measures are WTO-proof. Simulations show that both an import levy and an export refund restore competitiveness to a certain extent. BTAs may lower the costs for energy-intensive sectors, but induce higher costs for other sectors. This paper uses a general equilibrium model to quantify and assess the implications of a number of policy scenarios

    2016-06-01

    The EU Directive 95/46/EC on the protection of individuals with regard to the processing of personal data and on the free movement of such data aims at harmonising data protection legislation in the European Union. This should promote the free flow of products and services within the EU. This research found a wide variety of interpretations of the application of data protection legislation to geographic data. The variety was found among the different EU Member States, the different stakeholders and the different types of geographic data. In the Netherlands, the Data Protection Authority (DPA) states that panoramic images of streets are considered personal data. While Dutch case law judges that the data protection legislation does not apply if certain features are blurred and no link to an address is provided. The topographic datasets studied in the case studies do not contain personal data, according to the Dutch DPA, while the German DPA and the Belgian DPA judge that topographic maps of a large scale can contain personal data, and impose conditions on the processing of topographic maps. The UK DPA does consider this data outside of the scope of legal definition of personal data. The patchwork of differences in data protection legislation can be harmonised by using a traffic light model. This model focuses on the context in which the processing of the data takes place and has four categories of data: (1) sensitive personal data, (2) personal data, (3), data that can possibly lead to identification, and (4) non-personal data. For some geographic data, for example factual data that does not reveal sensitive information about a person, can be categorised in the third category giving room to opening up data under the INSPIRE Directive.

    2012-04-15

    Trends towards green shipping and green shipbuilding provide new market opportunities for the European shipbuilding and marine equipment sectors. The maritime transport sector is being incentivised to improve its environmental performance as a result of both market driven and regulatory greening trends. Examples of these trends are global regulation on NOx and SO2 emissions of ships, increased energy efficiency of new ships, ballast water management and an increased demand for offshore renewable energy generation. The European shipbuilding and marine equipment sectors have a leading position in high value, high complexity segments. It has a good starting position to contribute to the greening trends. This study identifies market opportunities for the EU shipbuilding industry that follow from greening trends in shipping and other areas. Taking the greening together, the global market potential for the period until 2020 is estimated to be minimally euro 12.5-15.5 bn per year. The study recommends that the EU enhances its cluster support provision, continues the promotion of the shipbuilding and marine equipment sectors as attractive work places, continues promoting the use of market based instruments at IMO level and consider adopting schemes at EU level. This report is built on an extensive market consultation process through in-depth interviews with over 35 stakeholders, complemented with a review of the state of the art literature and a stakeholder workshop. As such it is not a statistical analysis, or an academic or political analysis, but it represents an in-depth insight based on key market actors and industry players.

    Full Text Available In line with the world economy trend, the collapse in world trade in goods and services observed in the last quarter of 2008 intensified inthe first quarter of 2009, but the trough in growth rates has likely been reached; positive quarterly growth rates are expected by the end of 2009. UE-27 registered the slowest export growth of any region last year, with an expansion of just 0.0per cent, down from 3.5 per cent in 2007. Import growthturned negative in 2008, falling by 1 per cent (+3.5 per cent in 2007. If the 27 members of the European Union are considered collectively(excluding internal EU trade, the five leading exporters were the European Union (15.9 per cent of world exports, China (8.9%, the United States(8.1%, Japan (4.9% and Netherlands (3.9 per cent. Exports from the EU were worth US$ 1.93 trillion in 2008. Signs of recovery are not yet soclearly visible in the EU-27 like in USA, in the last part of 2009. Each country has its own specific combination of weaknesses such as burstinghousing bubbles, declining exports and damaged financial sectors. The eventual recovery is likely to be slow as rising unemployment will hitconsumer spending. In the above mentioned conditions, GDP in the euro area is expected to contract 4.8% in 2009 and to show 0% growth in 2010.The previous projections were for a 4.1% fall in 2009 and a 0.3% fall in 2010. The main factors with a positive influence, taken into consideration forrevising up the projections for 2010 in euro area are: the strengthening growth in world trade which will help support a turnaround in exports, thegovernmental policy support and an easing of financial conditions adopted in some countries.

    Full Text Available The article analyzes the development of EU — Russia energy relations through the lens of the evolution of three parameters: the political agenda (the Energy Dialogue, the institutional structure, and the legal modalities. The identification of these three aspects for assessing the evolution of EU — Russia energy relations is the novelty in the author’s approach. This study aims to identify the previous stages and assess the current state of EU — Russia energy dialogue, since they set out conditions for energy cooperation in the Baltic Sea region. This research is based on a political and legal analysis of various documents and employs various international relations theories (including integration theories. The article demonstrates that the EU nd Russia have made a transition to the integration agenda manifested in the Energy Dialogue (its current goal is the creation of a common European energy market. The author describes the process of gradual consolidation of transgovernmental and transnational institutions, which leads to depoliticization of cooperation and mutual socialization of the partners. Finally, legal discussions on the development of common rules have become more constructive. In sum, the current situation in EU — Russia energy relations is favourable and positively affects cooperation in the Baltic Sea region.

    Full Text Available The discussion about the possible taxation of the financial sector has started in the European Union as a result of the financial crisis which has spread to the Europe from the United States in 2008. European Commission concluded that EU should lead the efforts to introduce system of levies or taxies on financial institutions. EU member states individually committed to support the financial sector for a total about EUR 4.6 trillion (i.e. 39% of EU-27 GDP in 2009. Those public interventions have significant budgetary consequences (strongly felt in Greece, Spain or Italy and imposes a heavy burden on the present and future generations. Therefore there is a strong consensus not only on the level of the European Union but also internationally, that financial sector should contribute to the public finance more fairly. As a reaction on costs of the financial crisis which was paid out from the public money, some of the countries immediately introduced temporary measures in order to collect back paid out money. The aim of the paper is to research the possibility of financial sector taxation, to discuss the proposal of the European Union on the introduction of financial transaction tax on EU level and through the multi-criteria analysis to research, whether this type of the tax is suitable as an own resource of EU budget.

    TiO2(Eu)/CuO nanocomposites were prepared by precipitation method. The anatase nanocrystallites with a size of 26 nm exhibited well crystallized and characteristical dipyramidal morphology and {1 0 1} and {0 0 1} faceting. Transmission electron microscopy photographs with atomic resolution showed that the Eu(III) dopants were bounded on surface of titania. In the composites, the CuO nanocrystals exhibiting a monoclinic tenorite structure with a size in the range from 2 to 5 nm were grafted to the surface of titania. The influence of copper(II) oxide led to distinct selectivity in the photocatalytic and antimicrobial properties of the investigated TiO2(Eu)/CuO nanocomposites. While the presence of CuO nanocrystals strongly increased the photocatalytic production of hydrogen by ethanol reforming, it decreased the activity in photoinduced total mineralization of phenol comparing with non-modified TiO2(Eu). In investigated TiO2(Eu)/CuO powders, the photoinduced antimicrobial activity against membranes of Enterococcus species was influenced by the selective binding of CuO to the surface of the microorganism leading to distinct selectivity in their action. The activity against Enterococcus faecalis was higher than against Enterococcus faecium.

    In the past eight years, the European Association of Poisons Centres and Clinical Toxicologists (EAPCCT) has been intensively involved in a European Commission led process to develop EU legislation on the information of hazardous products that companies have to notify to EU Poisons Centres (or equivalent "appointed bodies"). As a result of this process, the Commission adopted Regulation (EU) No 2017/542, amending the CLP Regulation by adding an Annex on harmonised product submission requirements. Harmonised mixture information requirements: Detailed and consistent information on the composition of the hazardous product will become available to EU Poisons Centres (PC). The information will be submitted by companies to PCs (or equivalent "appointed bodies") using a web-based software application or in-house software. Two new important features are introduced. Firstly, to be able to rapidly identify the product formula, a Unique Formula Identifier (UFI) on the product label links to the submitted information. Secondly, for better comparability of reports on poisonings between EU member states, a harmonised Product Categorisation System will specify the intended use of a product. Rapid product identification and availability of detailed composition information will lead to timely and adequate medical intervention. This may lead to considerable reduction in healthcare costs. Additionally, for companies trading across the EU, costs of submission of this information will be reduced significantly. Next steps: From 2017, an implementation period has started, consisting of a three-year period for stakeholders to implement the new requirements, followed by a gradual applicability for consumer products (2020), professional products (2021) and industrial use-only products (2024). Technical tools to generate the electronic format and the UFI together with guidance documents are expected to be made available by the end of 2017 by the European Chemicals Agency (ECHA).

    Since 2010 we have observed a new quality in EU energy policy. It is related to the European Commission's more or less direct engagement in the bilateral gas relations of a part of the new member states - Poland, Bulgaria and Lithuania - with Russia. Although the long term outcome of this activity of the EC is as yet unclear it seems to be important for several reasons. Firstly it might increase the possibilities of the enforcement of the EU's directives liberalising the internal gas market and specifically their implementation in individual gas agreements with suppliers from third countries (Gazprom). The consistency and determination of the EC in this field may be decisive for the future direction and depth of the liberalization of the EU gas market. Furthermore, present developments may lead to an increase in EU and specifically EC competence in the field of energy policy, especially its external dimension. So what lessons can we draw from recent Commission activities on the following issues: - Implementing EU gas market 2. and 3. liberalization packages and their main provisions - EU energy policy and its external dimension - recent developments and the EU's role - EU-Russia gas relations - where Russian and EU interests diverge.

    Full Text Available Novel LiLa1−x−y(MoO42:xSm3+,yEu3+ (in short: LL1−x−yM:xSm3+,yEu3+ double molybdate red phosphors were synthesized by a solid-state reaction at as low temperature as 610 °C. The optimal doping concentration of Sm3+ in LiLa1−x(MoO42:xSm3+ (LL1−xM:xSm3+ phosphor is x = 0.05 and higher concentrations lead to emission quenching by the electric dipole—electric dipole mechanism. In the samples co-doped with Eu3+ ions, the absorption spectrum in the near ultraviolet and blue regions became broader and stronger than these of the Sm3+ single-doped samples. The efficient energy transfer from Sm3+ to Eu3+ was found and the energy transfer efficiency was calculated. Under the excitation at 403 nm, the chromaticity coordinates of LL0.95−yM:0.05Sm3+,yEu3+ approach to the NTSC standard values (0.670, 0.330 continuously with increasing Eu3+ doping concentration. The phosphor exhibits high luminous efficiency under near UV or blue light excitation and remarkable thermal stability. At 150 °C, the integrated emission intensity of the Eu3+ remained 85% of the initial intensity at room temperature and the activation energy is calculated to be 0.254 eV. The addition of the LL0.83M:0.05Sm3+,0.12Eu3+ red phosphors can improve the color purity and reduce the correlated color temperature of WLED lamps. Hence, LL1−x−yM:xSm3+,yEu3+ is a promising WLED red phosphor.

It had become an important topic for European agenda where CSR is considered as a concept whereby companies integrate social and environmental concerns in their business operations and interact with stakeholders on a voluntary basis. In general, it is the responsibility of enterprises for their impact on society. CSR and its certification is important not only for EU but also for out-European business partners such as China. This paper is focused on EU agenda related to CSR, certification, SA8000 standard and the case study of China in relation to SA8000. The results show that the interest in obtaining of SA8000 certificate has risen up to 3231 companies in 2013. European certified companies are represented by 1583 in 2013. The most developing regions in terms of SA8000 certification are Europe and Central Asia, resp. Europe, South Asia and East Asia and the Pacific. In Europe, the most SA8000 certified country is Italy with one third of certifications from the whole world. From out- European countries leading role is taken by India and China. China is the world biggest exporter in the apparel branch which has also the highest number of SA8000 certified companies.

    2013-08-01

    Straw mushrooms were grown on lead contaminated rice straw and stubble. Study materials were dried, acid digested, and analyzed for lead using flame atomic absorption spectrophotometry. The results showed the highest lead concentration in substrate was 445.350 mg kg⁻¹ in Treatment 3 (T3) and the lowest was BD (below detection) in Treatment 1 (T1). The maximum lead content in straw mushrooms was 5.072 mg kg⁻¹ dw in pileus of T3 and the minimum lead content in straw mushrooms was BD in egg and mature (stalk and pileus) stage of T1. The lead concentration in straw mushrooms was affected by the age of the mycelium and the morphology of mushrooms. Mushrooms' lead uptake produced the highest accumulation in the cell wall. Some lead concentrations in straw mushrooms exceeded the EU standard (>3 mg kg⁻¹ dw).

    The study evaluates the impacts of EU climate policy on the emission allowance price, electricity prices, the competitiveness of industry and macroeconomic developments in the third EU emission trading period 2013-2020. The economic impacts of climate policy on Finland are compared to the impacts on the entire EU area. It turns out that due to its cold climate and heating energy demand, higher export intensity of the economy and higher energy intensity of the industry Finland pays a higher price for EU climate policy in terms of output and employment losses than the EU on average. The study examines the macroeconomic effects of climate policy also in the more distant future, assuming that climate policy is tightened further in the 2020s. Climate policy implemented by emission trading means that the long-term economic growth in the EU area depends essentially on emission-free electricity production, and no longer on other growth factors, such as the labour supply and productivity growth.

    Ines Kersan-Škabić

    2017-01-01

    Full Text Available Contemporary trade analysis indicates the necessity of calculating trade in value added (TiVA which is created through global value chains (GVCs. This paper aims to determine the characteristics and importance of GVC trade in the EU new member states (EU NMS with special emphasis placed on the industry level. The results demonstrate different levels of GVC participation of the EU NMS, where Hungary is the most integrated country and Croatia the least integrated. Regional GVCs exist because a huge part of value added (VA comes from EU member states, as in gross export as well as in final demand (Europe as a hub. The most important source countries are Germany and Italy and there is also evidence of geographical and historical relations between the countries. The domination of backward participation has been found in the analysis made on the industrial level, i.e. the EU NMS are highly dependent on the import of intermediates for the production and export of final products. Strong interconnections between imports of intermediate products and exports of final products have been found in the manufacture of computers, electronics and optical products; manufacture of wood, paper, printing and reproduction. This research has contributed to the scarce literature concerning GVC (TiVA in EU NMS and has opened up new possibilities for further research and analysis.

    Experimental mesocosms are valuable tools to fill the gap between highly controlled/replicated lab experiments and uncontrolled/non-replicated natural environments such as rivers, lakes and oceans. WWW.MESOCOSM.EU is an open web-portal for leading aquatic mesocosm facilities around the world. It was created within the FP7 EU-project MESOAQUA (A network of leading MESOcosm facilities to advance the studies of future AQUAtic ecosystems from the Arctic to the Mediterranean). The goal of the portal is to increase international knowledge about existing mesocosm facilities, including information on locations, environment, equipment, contacts, research opportunities and mesocosm-based publications. MESOCOSM.EU specifically aims to be a tool to enhance the quality of research by facilitating international cooperative network building, announcement of new research initiatives, transfer of best practice, and dissemination of knowledge, public information and press releases. As an open platform for all aquatic ecosystem scale science (marine and freshwater), MESOCOSM.EU aims to fill the lack of a centralized, coordinating virtual infrastructure for international aquatic mesocosm research, from the mountains to the ocean and from polar to tropical regions.

    Limiting the rise in the average global temperature to 2C has been the EU goal since 1996, and in December 2010 the UN recognised the need to consider a 1.5C limit. Avoiding overshooting these levels will require massive emissions reductions - in the order of 80-95% for industrialised countries, like those in the EU. The next ten years are crucial in establishing whether society will be able to make this transition, or whether temperature increase limits will be irreversibly missed. Last year, the European Union Climate Policy Tracker (EU CPT) investigated each member state's implementation of policy and legislation, and rated their progress towards a 2050 vision of deep decarbonisation using renewable energy. The uniquely developed rating scheme, modelled on appliance efficiency labels (A-G), gave an indication of how member states were doing compared to a 'low-carbon policy package'. The average score was an 'E', indicating that the level of effort needed to treble, to be on a pace to reach the 2050 vision. However, aggregating best practices across sectors and countries doubled the score - meaning that the tools are already at hand for major improvements across Europe. This report builds on last year's EU CPT by giving an update on action in member states, and an indicative trend in the rating, as well as adding a new section on EU policy. The addition of an EU section is appropriate, with the Commission having produced a roadmap on a low-carbon economy by 2050, a transport white paper, and with another roadmap for 2050 focused on energy anticipated by the end of 2011. This report seeks to answer the question of whether these and other related initiatives are sufficient to help Europe reach its low-carbon goals. When interpreting the results of this report, it is important to understand that the goal underlying the vision here is not the same as the one in the European Commission's 'low-carbon economy' roadmap

    The tritium loading of current grades of advanced ceramic breeder pebbles with three different lithium orthosilicate (LOS)/lithium metatitanate (LMT) compositions (20–30 mol% LMT in LOS) and pebbles of EU reference material, was performed in a consistent way. The temperature dependent release of the introduced tritium was subsequently investigated by temperature programmed desorption (TPD) experiments to gain insight into the desorption characteristics. The obtained TPD data was decomposed into individual release mechanisms according to well-established desorption kinetics. The analysis showed that the pebble composition of the tested samples does not severely change the release behaviour. Yet, an increased content of lithium metatitanate leads to additional desorption peaks at medium temperatures. The majority of tritium is released by high temperature release mechanisms of chemisorbed tritium, while the release of physisorbed tritium is marginal in comparison. The results allow valuable projections for the tritium release behaviour in a fusion blanket.

    A major challenge for healthcare quality improvement is the lack of IT skills and knowledge of healthcare workforce, as well as their ambivalent attitudes toward IT. This article identifies and prioritizes actions needed to improve the IT skills of healthcare workforce across the EU. A total of 46 experts, representing different fields of expertise in healthcare and geolocations, systematically listed and scored actions that would improve IT skills among healthcare workforce. The Child Health and Nutrition Research Initiative methodology was used for research priority-setting. The participants evaluated the actions using the following criteria: feasibility, effectiveness, deliverability, and maximum impact on IT skills improvement. The leading priority actions were related to appropriate training, integrating eHealth in curricula, involving healthcare workforce in the eHealth solution development, improving awareness of eHealth, and learning arrangement. As the different professionals' needs are prioritized, healthcare workforce should be actively and continuously included in the development of eHealth solutions.

    Mesoporous structures are interesting materials for the incorporation of dyes, drugs, and luminescent systems, leading to materials with important multifunctionalities. In a very unique way, these guest/host materials combine the high stability of inorganic systems, new guest-structuring features, and adsorption mechanisms in their well-defined pores. This work evaluates the luminescent properties of rare earth-doped YVO 4 nanoparticles coated with a mesoporous silica shell. The use of two different synthesis methodologies allowed for particle size control. The crystalline phase emerged without further heat treatment. The mesoporous shell decreased undesirable quenching effects on YVO 4 :Eu 3+ nanoparticles and rendered them biocompatible. The materials prepared herein could have interesting applications as luminescent markers or drug release systems.

    2017-06-01

    The development of approaches to tackle the European Union (EU) water-related challenges and shift towards sustainable water management and use is one of the main objectives of Horizon 2020, the EU strategy to lead a smart, sustainable and inclusive growth. The EU is an increasingly water challenged area and is a major agricultural trader. As agricultural trade entails an exchange of water embodied in goods as a factor of production, this study investigates the region's water-food-trade nexus by analysing intra-regional virtual water trade (VWT) in agricultural products. The analysed period (1993-2011) comprises the enactment of the Water Framework Directive (WFD) in the year 2000. Aspects of the VWT that are relevant for the WFD are explored. The EU is a net importer of virtual water (VW) from the rest of the world, but intra-regional VWT represents 46% of total imports and 75% of total exports. Five countries account for 60% of total VW imports (Germany, France, Italy, The Netherlands, Belgium) and 65% of total VW exports (The Netherlands, France, Germany, Belgium and Spain). Intra-EU VWT more than doubled over the period considered, while trade with extra-EU countries did not show such a marked trend. In the same period, blue VWT increased significantly within the region and net import from the rest of the world slightly decreased. Water scarce countries, such as Spain and Italy, are major exporters of blue water in the region. The traded volumes of VW have been increasing almost monotonically over the years, and with a substantial increase after 2000. The overall trend in changes in VWT does not seem to be in accordance with the WFD goals. This study demonstrated that VWT analyses can help evaluate intertwining effects of water, agriculture and trade policies which are often made separately in respective sectors.

    Highlights: • Nanocomposites composed of Eu-doped anatase grafted with CuO. • Increase in photocatalytic hydrogen production due to CuO acting as electrons sink. • CuO in composites decreasing the photoinduced total mineralization of phenol. • Selective photoinduced antimicrobial activity against Enterococcus species. - Abstract: TiO 2 (Eu)/CuO nanocomposites were prepared by precipitation method. The anatase nanocrystallites with a size of 26 nm exhibited well crystallized and characteristical dipyramidal morphology and {1 0 1} and {0 0 1} faceting. Transmission electron microscopy photographs with atomic resolution showed that the Eu(III) dopants were bounded on surface of titania. In the composites, the CuO nanocrystals exhibiting a monoclinic tenorite structure with a size in the range from 2 to 5 nm were grafted to the surface of titania. The influence of copper(II) oxide led to distinct selectivity in the photocatalytic and antimicrobial properties of the investigated TiO 2 (Eu)/CuO nanocomposites. While the presence of CuO nanocrystals strongly increased the photocatalytic production of hydrogen by ethanol reforming, it decreased the activity in photoinduced total mineralization of phenol comparing with non-modified TiO 2 (Eu). In investigated TiO 2 (Eu)/CuO powders, the photoinduced antimicrobial activity against membranes of Enterococcus species was influenced by the selective binding of CuO to the surface of the microorganism leading to distinct selectivity in their action. The activity against Enterococcus faecalis was higher than against Enterococcus faecium.

  15. The impact of the EU emissions trading scheme on the price of electricity in the Netherlands

    2004-02-01

    In this paper a specific aspect of the proposed EU Emissions Trading System (EU ETS) is discussed, namely the potential impact of the EU ETS on the price of electricity in the Netherlands and, hence, the potential implications for Dutch power producers and consumers. It shows that the EU ETS may lead to a significant increase in the price of electricity in the Netherlands (and other EU Member States), depending on the marginal costs of emissions trading (i.e. the price of an emission allowance), the emission factor of the marginal production technology to generate electricity, and the extent to which the costs of emissions trading will be passed on to the end-users of electricity. If, for one reason or another, these costs will not be passed on to power consumers, it will have an adverse impact on overall efficiency from both an energy and economic point of view. On the other hand, if - as expected - these costs are indeed passed on to end-users of electricity, it will benefit power producers (mainly owing to the economic rent of allocating emission allowances for free), while it will harm those energy-intensive industries that, in turn, are not able to pass the higher electricity costs to their customers (resulting in a loss of economic production and income). To some degree, these effects can be best avoided by auctioning emission allowances mandatory throughout the EU ETS and using the auction revenues to reduce the overall level of taxation and social premiums in order to improve the overall competitiveness of domestic industries and to (partly) compensate power consumers for the ET-induced increase in the price of electricity

    Over the past few years, the highest Dutch court of justice has rejected many building plans for new homes, roads and businesses because of reasons related to EU air quality limit values. This has made it clear that detailed impact assessments are necessary to having plans approved for permits, and that failure to achieve limit values can be a reason to reject a plan. An investigation to see whether such issues have also played a role in other EU countries has proven the contrary. Only a few similar court cases have taken place in other countries, while air quality limit values are breached in other EU countries as well. The reason is that the Netherlands has implemented the first EU Daughter Directive in a relatively strict manner in comparison to other countries, in particular: Adopting a strict legal coupling of air quality and spatial planning policies, with many types of plans being subject to an air quality impact assessment; Perceiving limit values as absolute limit values, whereas in many other countries a need to meet a limit value is weighted with other interests in granting permits; Applying limit values to the whole country. Although this application is, in principle, valid for all EU member states, some member states apply limit values only to locations where people can be exposed; Since air quality assessment is detailed in the Netherlands, many locations are appointed where air quality limit values are breached. Clearly, the role of limit values in granting permits for plans differs considerably among the EU countries, while the underlying EU legislation is the same, and while limit values are breached in other countries as well [nl

    Full Text Available The purpose of this paper is threefold. First, we review the mechanisms and determinants of vertical specialization (VS, as this has gradually become the dominant characteristic of international trade. Second, we underline that there is a rich literature regarding VS in EU trade, at aggregate and individual levels and research is advancing together with the instruments used to measure trade in value added. Third, our investigation brings to the forefront a classification of EU countries according to their GVC participation index, taking into consideration both upstream and downstream links. As a conclusion, the VS analyses help us better understand the interconnectedness among countries and industries by means of foreign direct investment, trade, labour migration and technology transfer.

  3. Fighting windmills? EU industrial interest and global climate negotiations

    Steiner Brand, U.; Tinggaard Svendsen, G.

    2003-01-01

    Why has the EU been so eager to continue the climate negotiations? Can it be solely attributed to the EU feeling morally obliged to be the main initiator of continued progress on the climate change negotiations, or can industrial interests in the EU, at least partly, explain the behaviour of the EU? We suggest that the EU has a rational economic interest in forcing the technological development of renewable energy sources to get a fast-mover advantage, which will only pay if a sufficient number of countries implement sufficiently stringent GHG reductions. The Kyoto Protocol, which imposes binding reductions on 38 OECD countries, implies that, as a first-mover, the EU will be to sell the necessary new renewable technologies, most prominently wind mills, to other countries, when they ratify and implement the Kyoto target levels. In the latest EU proposal made in Johannesburg, the EU pushed for setting a target of 15% of all energy to come from sources such as windmills, solar panels and waves by 2015. Such a target would further the EU's interests globally, and could explain, in economic terms, why the EU eagerly promotes GHG trade at a global level whereas the US has left the Kyoto agreement to save the import costs of buying the EU's renewable systems.

    Controlled formation of aggregates having organized structure of cube-shaped EuS nanocrystals is reported. The EuS aggregates in liquid media (methanol) were obtained by means of van der Waals interaction between EuS nanocrystals. The packing structure of the EuS aggregates is characterized with transmission electron microscopy (TEM) and small angle X-ray scattering measurements (SAXS). TEM image indicates the EuS nanocrystals form self-aggregated 2D orthogonal lattice structure. The diffraction peak of (111) of SAXS profile shows that the cube-shaped EuS form 3D cubic superlattice. We successfully demonstrated that the aggregates of cube-shaped EuS nanocrystals formed cubic stacking structure.

    1998-01-01

    The European Union with 15 Member States at the end of the century and with 6 more countries in the accession phase has set up certain instruments which enhance energy cooperation among them and with third countries. The major dimensions of EU energy policy presented in the White Paper are the external dimension - globalization of markets, the increasing environmental concern, the technology developments and the EU institutional responsibilities. To contribute to these, certain EU initiatives and supporting actions are undertaken through the energy and the broader co-operation programmes like THERMIE, SYNERGY, SAVE, ALTENER, PHARE, etc. The THERMIE programme supports the demonstration application and dissemination of innovative and successful energy technologies. SYNERGY is a programme for energy co-operation with third countries in energy policy and strategy implementation issues. SAVE and ALTENER concentrate on the promotion and enhancement of energy efficiency practices and use of renewable respectively. PHARE is a technical assistance programme addressed to Eastern European Countries which are in the phase of transition to market economy. There are also other initiatives like the Transeuropean Energy Network (TEN) and the activities managed by the financial institutions namely the European Bank for Reconstruction and Development (EBRD) and the European Investment Bank (EIB). All this context of programmes and initiatives is modified from period to period in order to serve the EU energy policies and the developments in the energy markets. The recent agreement which came up from the Kyoto conference has actually influenced the direction of actions towards more intensive amelioration of environmental pollution. (author)

  13. DEINDUSTRIALIZATION AS A PROCESS IN THE EU

    2017-01-01

    Full Text Available Deindustrialization is a natural process in the developed countries, which takes place under the influence of external and internal factors and occurs as a result of economic growth. It is marked by the decline in the share of industry in GDP and employment with a simultaneous increased importance of the service sector. Considering the complexity of the concept, there are many theoretical approaches of deindustrialisation. In this paper the analysis of deindustrialization in the EU was conducted. The research results indicate the existence of relative deindustrialization in the EU, which is characterized by reduced share of agriculture and industry and increased share of the service sector in GDP. Also, it was found that the decrease in employment in the industry was not created as a result of a decrease in industrial production. The EU economy, including the industrial sector, is heavily influenced by the globalization process, while the process of deindustrialization is significantly impacted by the increased volume of foreign direct investment. In key strategic documents European industry is recognized as the main "engine" of the recovery of the European economy. Therefore, the highest  priority is the creation of conditions for the process of reindustrialization, i.e. the development of industry in the variable circumstances, with an emphasis on strengthening and improving the industrial foundation and implementation of new solutions based on innovation, research and new technologies.

    2018-05-01

    Full Text Available In January 2018 the EU has released two proposal designed to simplify the VAT system, specifically around reduced rates, and to reduce compliance costs of smaller businesses in respect of VAT. The EU's common rules on VAT rates do not treat Member States equally. More than 250 exemptions allow several Member States much more flexibility in setting VAT rates than others. While these derogations are due to expire once the reformed VAT system comes into place, the rates proposal will ensure that all Member States have the same flexibility and a uniform structure in which to set their own VAT rates. The second proposal is designed to make trading in other EU member states easier for smaller businesses. Currently, small businesses may benefit from generous thresholds in their state of establishment, but zero thresholds exist for nonestablished businesses, meaning higher compliance costs. The intended proposals will provide simplification measures (around invoicing, record keeping etc. for businesses with a turnover not exceeding €2 million and will allow member states to apply thresholds to non-established businesses with a turnover not exceeding €100,000.

  16. The EU's Antidumping Actions Against Chinese Products

    2014-10-01

    Full Text Available As the importance of tariffs in international trade has declined with the reduction of tariff rates under the GATT/WTO programs of multilateral trade liberalization, most governments prefer to protect domestic industries from foreign competitors through a variety of non-tariff barriers. Antidumping actions have recently become the world's biggest trade impediment due to their specific features and the antidumping activity of new users. Since China has become the major engine of world trade growth in recent years, it also has become the largest anti-dumping target in the world. However, the present world competition situation implies that world trade liberalization might arouse regional trade friction. The objective of this research is to identify whether China's WTO accession changed China's situation with regard to EU antidumping actions. The research analysis empirically proved that trade liberalization could partly affect the EU's antidumping actions against Chinese exports and the higher degree of industrial concentricity becomes a motive to increase the EU's antidumping activities against China.

    2007-01-01

    Equilibria and kinetics of exchange of both Zn2+ and Eu3+ ions on a composite ion-exchanger, cobalt hexacyanocobaltate (III) (CoHCC) incorporated in polyacrylonitrile (PAN), has been studied. The apparent capacity of CoHCC-PAN for Zn2+ and Eu3+ was determined and found to be 0.353 and 0.69 meq/g, respectively. The higher capacity for Eu3+ ions than that for Zn2+ ions is due to the higher electrostatic interaction strength of the higher charge ion with the surface. Freundlich and Langmiur adsorption isotherms were used to investigate solute (Zn2+ or Eu3+) exchange phenomenon at the liquid/solid interface. The results indicated that both Langmuir and Freundlich isotherms fit well for both Zn2+ and Eu3+. Sorption data have been also treated with the Dubinin-Radushkevich equation. The kinetics of Zn2+ or Eu3+ sorption on the composite seems to show that the reaction was proceed via two steps. The first one was fast and probably due to adsorption followed by a slow exchange reaction. In view of the data obtained on the effect of particle size and metal ion concentrations on the rate of exchange reaction, it is concluded that the mechanism for both ions was chemical control. Generally, it seems that there are two exchange sites chemically equivalent but present in pores of different sizes which lead to different degrees of dehydration of the ions sorbed on the two sites

    2017-03-01

    Full Text Available Initially, the European Union had a purely economic connotation, as his intent was the free movement of factors of production, in order to create a competitive internal market and achieving a rational distribution of resources. For this reason, the individual was seen simply as a worker and for this purpose the first aspects that are disciplined within the EU are those contained in this sphere. In the Treaty of Rome, which established the European Economic Community (EEC, the freedom of free movement was reserved for only a few special categories of workers, who were active subjects economically, since what resulted essential at the time was the creation of an internal market. Later the Maastricht Treaty, on one side marks the transition from the EEC to the EU, on the other presents for the first time the "European citizenship", making the free movement an autonomous right of every citizen belonging to a Member State. In this way the free movement is exercised not only for the economic purposes of the Treaties. In December 2000 the Charter of Fundamental Rights or the Charter of Nice was compiled and signed, which defines that the EU seeks to promote a balanced development and ensures free movement of persons, goods, services and capital, and also the freedom of residence. Main objective of this manuscript is an analysis of the differences and similarities between the EU and non-EU citizens.

  19. Gas and coal competition in the EU Power Sector

    International Nuclear Information System (INIS)

    Cornot-Gandolphe, Sylvie

    2014-06-01

    Despite its many assets, a confluence of factors - including flat electricity demand, rising use of renewable energy sources, falling wholesale electricity market prices, high gas prices relative to coal and low CO 2 prices - has eroded the competitiveness of natural gas in the EU power sector. The share of natural gas in the EU electricity mix has decreased from 23% in 2010 to 20.5% in 2012. By contrast, coal-fired power stations have been operating at high loads, increasing coal demand by the sector. This thorough analysis by CEDIGAZ of gas, coal and CO 2 dynamics in the context of rising renewables is indispensable to understand what is at stake in the EU power sector and how it will affect future European gas demand. Main findings of the report: - Coal is likely to retain its cost advantage into the coming decade: The relationship between coal, gas and CO 2 prices is a key determinant of the competition between gas and coal in the power sector and will remain the main driver of fuel switching. A supply glut on the international coal market (partly because of an inflow of US coal displaced by shale gas) has led to a sharp decline in coal prices while gas prices, still linked to oil prices to a significant degree, have increased by 42% since 2010. At the same time, CO 2 prices have collapsed, reinforcing coal competitiveness. Our analysis of future trends in coal, gas and CO 2 prices suggests that coal competitive advantage may well persist into the coming decade. - But coal renaissance may still be short-lived: Regulations on emissions of local pollutants, i.e. the Large Plant Combustion Directive (LCPD) and the Industrial Emissions Directive (IED) that will succeed it in 2016, will lead to the retirement of old, inefficient coal-fired power plants. Moreover, the rapid development of renewables, which so far had only impacted gas-fired power plants is starting to take its toll on hard coal plants' profitability. This trend is reinforced by regulation at EU or

  20. Sharing Lessons Learned Between Industries in EU

    Muehleisen, A.; Strucic, M.

    2012-01-01

    Recent events in nuclear industry remind us on importance of continuous sharing of the knowledge and experience gained through evaluations of incidents and accidents. We frequently use experience from our daily life activities to improve our performance and avoid some mistakes or unwanted events. In the similar way we can use other industries experience. These experiences can be applied to improve nuclear safety. For example, Safety Culture, which has a great influence on the level of nuclear power plants safety, is similarly presented in other industries. Mechanisms which led to accidents from weak safety culture in one branch of other industry could be comparable to those in nuclear industry. Some other industries have many more cumulative years of experience than nuclear industry. Aviation and Oil industries are typical representatives. Part of their experience can be used in nuclear industry too. Number of reports from nuclear power plants showed us that not only specific equipment related causes lay behind accidents; there are also other causes and contributors which are more common for all industries. Hence lessons learned in other industry should be assessed and used in nuclear industry too. In the European Union, a regional initiative has been set up in 2008 in support of EU Member State nuclear safety authorities, but also EU technical support organizations, international organizations and the broader nuclear community, to enhance nuclear safety through improvement of the use of lessons learned from operational experience of nuclear power plants (NPPs). The initiative, called ''the EU Clearinghouse on Operational Experience Feedback for NPP'', is organized as a network operated by a centralized office located at the Joint Research Centre of the European Commission. The reduction of occurrence and significance of events in NPPs and their safe operation is its ultimate goal. Among others EU Clearinghouse provides services such as technical and scientific

  1. EU Think Tank Fora as Transaction Cost Reducers: A Study of Informal Interest Intermediation in the EU

    Directory of Open Access Journals (Sweden)

    Marybel Perez

    2014-05-01

    Full Text Available By examining the organisational structure of EU think tank fora (seminars, workshops and conferences, this article proposes that fora can play the role of transaction cost reducers in EU policymaking. I argue that certain aspects of EU policymaking, including i controlled processes of consultation, ii diminishing costs of management, and iii the risk of state capture, incentivise EU institutions to outsource part of the consultation activity to policy actors that can help EU institutions fulfil their informational and legitimacy needs. I argue that think tanks are able to play this role because they i reduce information asymmetries by connecting a wide variety of policy actors and ii act as intermediaries that mitigate opportunistic behaviour. The empirical assessment reveals that the dimensions characterising transactions are present in EU think tank fora. It shows that policy actors that do not usually participate in formal consultation processes frequently attend fora where they meet representatives of EU institutions, particularly Parliament and Commission representatives.

    Ni/EuS multilayers with excellent multilayer sequencing are deposited via e-beam evaporation on the native oxide of Si(100) wafers at 4 × 10{sup −9} millibars. The samples have very small surface and interface roughness and show sharp interfaces. Ni layers are nanocrystalline 4–8 nm thick and EuS layers are 2–4 nm thick and are either amorphous or nanocrystalline. Unlike for Co/EuS multilayers, all Eu ions are in divalent (ferromagnetic) state. We show a direct antiferromagnetic coupling between EuS and Ni layers. At room temperature, the EuS layers are spin-polarized due to the proximity of Ni. Therefore, Ni/EuS is a candidate for room-temperature spintronics applications.

  3. The Normality of EU Sport Policy Studies: Disciplinary Locus in Political Science, Sport Science or Elsewhere?

    Full Text Available The Normality of EU Sport Policy Studies: Disciplinary Locus in Political Science, Sport Science or Elsewhere? Mainstream European integration research has shown that research on the EU tends to follow the conjunctures of European integration itself. This realisation has led to some debate on which branch of political science – international relations or government – or indeed other academic disciplines is/are the most appropriate locus for such research. The paper takes these debates one step further by looking at the occurrence of ‘EU & sport’ studies within the wider field of EU studies. The main material used comes from the ECLAS database. Findings lead to a discussion of whether ‘EU & sport’ studies should rather be for EU specialists or for sport specialists and a plea for disciplinary normalisation whereby sport science would need to get more directly involved (without necessarily overwriting political science. Some ideas are added regarding the need for a mapping of Central & Eastern European scholarship. Normalita politických studií EU v oblasti sportu: místo v oborech politologie, sportovních vědách či jinde? Hlavní integrační proudy v evropském výzkumu dokumentují, že výzkum v EU má tendenci zkoumat evropskou integraci jako takovou. Toto poznání vedlo k diskusi, v kterém oboru politologie – mezinárodní vztahy či vláda – nebo i v jiných akademických disciplínách je nejvhodnější místo pro takový výzkum.

    Gd{sup 3+} and Eu{sup 3+} ions co-doped CaCO{sub 3} nanoparticles have been successfully synthesized via carbonization method. The emission spectra of co-doped CaCO{sub 3} phosphors in the range of VUV–vis spectral were studied. The results reveal that the co-doped CaCO{sub 3} phosphors show intense red emission in the VUV range because of the Gd{sup 3+} ions as sensitizers. The energy transfer process from Gd{sup 3+} to Eu{sup 3+} in CaCO{sub 3}:Gd{sup 3+}/Eu{sup 3+} phosphors was investigated and discussed in terms of the luminescence spectra and the decay curves, which demonstrated that the energy transfer of Gd{sup 3+}→Eu{sup 3+} is efficient. The mechanism of energy transfer from Gd{sup 3+} to Eu{sup 3+} is a resonant transfer, in which electric dipole–dipole interaction plays a leading role. Furthermore, the effect of doping concentration of Eu{sup 3+} ions on the energy transfer efficiency was also investigated. From the photoluminescence (PL) spectra, it was also found that the incorporation of Na{sup +} ions into CaCO{sub 3}:Gd{sup 3+}/Eu{sup 3+} could lead to a remarkable increase of luminescent intensity due to the charge compensation.

  5. Carbon pricing in the EU: Evaluation of different EU ETS reform options

    2016-01-01

    This paper studies various options to support allowance prices in the EU Emissions Trading System (ETS), such as adjusting the cap, an auction reserve price, and fixed and variable carbon taxes in addition to the EU ETS. We use a dynamic computable general equilibrium model that explicitly allows for allowance banking and for a detailed cost-effectiveness analysis at the EU Member State level. We find that tightening the cap provides an ad hoc solution to the fundamental issue of the robustness of the effective carbon price, while introducing a price component to the ETS brings structural carbon price support in times of negative demand shocks for emission allowances. These price-based policies still benefit from the intertemporal flexibility through the banking provision in the EU ETS by re-allocating emissions over time with stronger emission reductions in early years and emission increases in later years. A higher emission price has a larger negative impact on the new Member States' economies than on other Member States. Furthermore, introducing a carbon tax in addition to the EU ETS decreases the price of allowances, resulting in welfare gains for net buyers of allowances while net sellers are worse off. - Highlights: • We analyse reform options for European Union Emission Trading System (EU ETS) with a CGE model. • Variable carbon tax and auction reserve price support carbon price at least cost. • Price-based reforms decrease early emissions but increase later emissions through banking. • New Member States' economies are affected more than others by higher CO_2 prices. • Lower allowance prices due to a carbon tax are unfavourable to net sellers of allowances.

  6. EU import restrictions on genetically modified feeds: impacts on Spanish, EU and global livestock sectors

    2010-07-01

    Over the last decade, much controversy has surrounded the usage of genetically modified organism (GMO) technology in commercial agriculture. More specifically, it is feared that GMOs may introduce new allergens into the food chain or contribute to antibiotic resistance. At the current time, the European Union (EU) adopts a zero tolerance policy toward non-approved GMO imports, whilst the approval process has not kept pace with the proliferation of new GMO varieties. In the EU livestock sectors, this apparent mis-match threatens to interrupt supplies of high protein feed inputs (e.g., soy meal) from countries with more relaxed regulations regarding GMOs. Employing a well known multi-region computable general equilibrium framework, this study quantitatively assesses the impact of a hypothetical EU import ban on unapproved GMO varieties of soybean and maize imports on livestock, meat and dairy sectors. The model code is heavily modified to improve the characterisation of the agricultural sectors and land usage, whilst a realistic baseline is employed to update the global database to 2008, the year the hypothetical ban is implemented. In the worst case scenario, there are significant competitive losses in EU livestock, meat and dairy sectors. In Spain, the negative impacts are particularly pronounced given the importance of pig production in agriculture. In contrast, all non-EU regions trade balances improve, with notable trade gains in the USA and Brazil. To conclude, the EU must urgently find a long term strategy for GMOs if it is to reconcile political expediency with pragmatic economic concerns. (Author) 21 refs.

  7. The Limits of Conditionality: Turkey – EU Taxation Negotiations

    2015-10-01

    Full Text Available Conditionality is mostly defined as the EU policy engendered for candidate countries. However, the mere use of conditionality by the EU does not essentially explain transferring of policies and EU rules towards the candidate countries. EU conditionality may be considered as a comprising approach but in certain policy areas or countries it might not be as successful as it was on other ones. The EU conditionality basically defined as a bargaining policy of affecting through reward, under which the EU provides inducements to candidate or neighbor countries to aligning with the conditions of the EU. In this study the explanatory power of conditionality would be questioned; so the main question will be “to what extent does the EU have influence on policy convergence in a candidate country that does not have a clear membership perspective? Taxation chapter in accession negotiations between Turkey and the EU has been chosen as the case of this research as providing to have an answer on this question. The main objective of this paper is ‘analyzing the extent of EU conditionality on Turkish taxation policy.’ Furthermore, it is argued in this study that “without a concrete incentive, European Union’s impact on a candidate country would be limited.”

    Effective photoswitchable europium sulfide nanocrystals with gold nanoparticles using dithiol (DDT: 1,10-decanedithiol) joint molecules, EuS-Au nanosystems, are demonstrated. The TEM image indicates the formation of EuS-Au nanosystems composed of cube-shaped EuS nanocrystals and spherical Au nanoparticles. Under visible-light irradiation, a drastic change of absorption band of EuS-Au nanosystems at around 600 nm was observed. The Faraday effects of EuS-Au nanosystems were estimated using magnetic circular dichroism (MCD) measurements. The effective change of the MCD spectra of EuS-Au nanosystems under visible-light irradiation was successfully observed at around 670 nm for the first time. The effective reversible changes in MCD spectra with the alternative irradiation cycles of visible light (>440 nm) and dark are also presented. The decrease rate of rotation angle at 670 nm of EuS-Au nanosystems is larger than that of absorbance. These results indicate that the effective change of MCD spectra of EuS-Au nanosystems would be dominated not only by a drastic change of absorption band related to enhanced LSPR of Au nanoparticles but also by specific interaction between EuS and Au in nanosystem under irradiation.

  9. Should the EU climate policy framework be reformed?

    Directory of Open Access Journals (Sweden)

    David ELLISON

    2011-12-01

    Full Text Available Though to-date the European Union (EU has played the most significant leadership role in international negotiations to reduce greenhouse gas (GHG emissions, the emission-reducing performance of individual EU Member states has for many been less than stellar. Several EU15 Member states continue to raise rather than lower emissions. Analysing the most successful policy instruments, this paper argues EU policy efforts could benefit from three important innovations. The following strategies – the adoption of an EU-wide FIT (feed-in tariff, an EU-wide carbon tax and more flexibility in the trading of carbon credits – could significantly improve emission reductions, their relative cost-efficiency and spread burden-sharing more evenly across technologies and Member states. This raises important questions, both about the effectiveness of EU and Kyoto-style commitments, as well as the EU Emission Trading Scheme (ETS. The commitment strategy, and in particular the EU ETS mechanism, have had the smallest impact on emission reductions. The proposed set of strategies could make a far greater contribution to future EU efforts and potentially lock in the impressive progress already made. Such a policy shift, if successful, would also greatly enhance the EU’s already significant credibility and bargaining power in international climate negotiations.

    LaVO 4 phosphors were synthesized by using a solid state reaction, and were characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence (PL). The XRD patterns of the Li-doped LaVO 4 :Eu 3+ powder phosphors revealed a mixture of tetragonal and monoclinic phases. The tetragonal phase of the LaVO 4 :Eu 3+ phosphor showed a higher PL intensity than the monoclinic one, despite the presence of both monoclinic and tetragonal structures. The Li-doped LaVO 4 :Eu 3+ powder phosphors absorbed strongly at 396 nm and exhibited strong red emission at approximately 619.5 nm due to the 5 D 0 → 7 F 2 transition. The incorporation of Li + ions into the LaVO 4 :Eu 3+ powder can lead to a remarkable increase in photoluminescence. The enhanced luminescence is attributed to the incorporation of Li + ions that may act as a sensitizers for effective energy transfer. This phosphor has promising applications in near-UV light-emitting diodes(LEDs).

    Kohlhaas, Michael; Schumacher, Katja; Diekmann, Jochen; Schumacher, Dieter; Carmes, Martin

    2005-01-01

    In October 2003, the European Union introduced a Directive, which widens the scope of the EU's minimum taxation system from mineral oils to all energy products including coal, natural gas and electricity. It aims at reducing distortions that currently exist between Member States as well as between energy products. In addition, it increases previous minimum tax rates and thus the incentive to use energy more efficiently. The Directive will lead to changes in the energy tax schemes in a number of countries, in particular some southern Member Countries (Greece, Spain, Portugal) and most of the new Member States. In this paper, we analyze the effects of the EU energy tax harmonization with GTAP-E, a computable general equilibrium model. Particular focus is placed on the Eastern European countries, which became new members of the EU in May 2004. We investigate the effects of the tax harmonization on overall economic growth and sectoral development. Special attention is paid to international trade in order to analyze if competitiveness concerns, which have been forwarded in the context of energy taxation are valid. Furthermore, the effect on energy consumption and emissions and thus the contribution to the EU's climate change targets is analyzed

    Full Text Available This paper is focussed on the financial packages and fiscal stimuli measures taken by EU as a group and by each EU country for supporting hard-hit sectors like automotive industry, tourism and construction. The economic crisis from 2008-2009 has led to a sharp decrease of investment climate and a massive contraction of economic activity. This means a sharp decrease of capacity utilisation that had led in time to an excessive unemployment especially in the most hit sectors. The financial rescue measures of EU are comprised in European Economic Recovery Plan (EERP. Measures approved are different from country to country, depending by the political support and the strategy chosen by the government. The EU's response to support the real economy during the economic crisis has been taken very fast and well-organized in certain countries and industries. By contrary, some Member States' recovery measures has been approved late and the rescue strategy wasn’t enough achieved. This has led to a deepening of financial instability and unemployment.

    Jansen, H.; Klaassen, G.

    2000-01-01

    In March 1997 the European Commission adopted a proposal that increases existing minimum levels of taxation on mineral oils by around 10 to 25% and introduces excises for other energy products. This paper analyses the macroeconomic impacts of the proposal. It employs three models: HERMES, GEM-E3, and E3ME. All models confirm that the proposal will have positive macroeconomic impacts when the tax revenues are used to reduce social security contributions paid by employers. For the EU as a whole, both GDP and employment are expected to be higher and CO2 emissions are 0.9 to 1.6 percent lower. The positive EU-wide effects can be observed in practically all member states. The sector impacts are modest, with the energy sector expected to face the most negative impacts. Differences between model results are due to the model type (general equilibrium or macro-econometric), the EU countries covered and the way tax exemptions were handled. Crucial assumptions to obtain the 'double dividend' are the modelling of the labour market and the impacts on EU external trade. The sensitivity of the results for the use of tax revenues, tax exemptions and tax rate increases is assessed. 21 refs

  5. Energy security of supply under EU climate policies

    Groenenberg, H.; Wetzelaer, B.J.H.W.

    2006-12-01

    The implications of various climate policies for the security of supply in the EU-25 were investigated. The security of supply was quantified using the Supply/Demand (S/D) Index. This index aggregates quantitative information on a country's energy system into one single figure. It takes a value between 0 and 100, with higher values indicating a more secure energy system. The S/D Index was calculated for the year 2020 based on the information in a series of policy scenarios, including a baseline (S/D Index 50.7), an energy efficiency scenario (53.8), two renewable energy scenarios (52.6 and 53.3) and two scenarios with combined policies (55.9 and 55.6).The S/D Index proved a useful indicator for assessing the implications of climate policies for the security of supply. As climate policies become more stringent, CO2 index fall, and the S/D index increases. The magnitude of the changes in the two indices is not always similar however. Major falls in CO2 indices in the order of 20% for two scenarios with combined energy efficiency and renewable energy polices lead to less noteworthy improvements in the associated S/D indices. Nevertheless, this combination of policies leads to the greatest improvements in the security of supply

    The Ukrainian crisis serves as a reminder just how much Ukraine plays a determining role for the European Union in energy matters, being the funnel through which most of Russian gas has to pass to reach Western Europe. One inevitable conclusion is already obvious: Russia and the EU are intimately linked and Moscow is as dependent on the EU for foreign exchange as is the EU on Russia for its gas. Nevertheless, the absence of stability in Ukraine constitutes a permanent threat to supplies to member states of the EU, especially Germany. (author)

  7. The Eastern Partnership and the EU-Turkey Energy Relations

    Directory of Open Access Journals (Sweden)

    Demiryol Tolga

    2014-10-01

    Full Text Available This article discusses the prospects and challenges of energy cooperation between the European Union (EU and Turkey within the context of the Eastern Partnership (EaP. Part of the EaP agenda is to advance energy cooperation between the EU and the partner states, particularly regarding the diversification of import routes. As an energy corridor between the EU and the hydrocarbon-rich Caspian states, Turkey is a strategic asset for European energy security. Turkey also has economic ties and political capital in the Caspian region that can help the EU reach out to its eastern partners. Despite robust incentives for cooperation, however, the EU-Turkey energy partnership has so far failed to meet mutual expectations. This article argues that this is primarily due to the inability of the two actors to credibly commit to regional energy cooperation. Commitment problem stems from two factors. First, the predominance of national energy interests over communal ones undermines credible commitment. The variation in energy needs of Member States prevents the EU from acting in unison in external energy policy. Similarly, Turkey also prioritizes its own energy security, particularly in its relations with suppliers, which undermines cooperation with the EU. Second, the EU and Turkey hold divergent perspectives on the potential political payoffs of energy cooperation. Turkish decision makers are convinced that energy cooperation warrants palpable progress in Turkey’s accession while most EU actors appear hesitant to establish a direct connection between energy and accession.

    The CO2MPARE model supports national and regional authorities in making balanced decisions for their investment portfolio under their regional development programmes, in particular under their Operational Programmes of EU Regional Policy. The EU's climate objectives require that investments across the EU are channeled towards low-carbon development. The carbon impacts of investments should therefore be seriously considered in the decision making process of regional development programmes. The CO2MPARE model informs national and regional authorities on the impacts that the investments under various Operational Programmes can have in terms of CO2 emissions. Knowing which investments lead either to additional emissions or rather to emission reductions, and what the overall impact of a programme is, represents the first step towards investment decisions that have decarbonisation co-benefits. CO2MPARE estimates the combined carbon impact of all activities that take place under a programme, and provides insights into the relative contributions of the different themes. Through its high aggregation level, it allows comparison of investment scenarios rather than individual projects. As such, it aims to support informed decisions on investment strategies rather than project investment decisions. In doing so, it also helps to build and develop a 'carbon culture' within the authorities directly or indirectly in charge of managing Regional Policy Operational Programmes. The model is primarily aimed at Operational Programmes co-financed by the European Regional Development Fund (ERDF)

    The new Council Directive 2013/59/EURATOM regarding radiation protection (EU-BSS) contains comprehensive regulations regarding radon protection in dwellings, in public buildings, and at workplaces for the first time. Key elements are the specification of a reference level of maximum 300 Bq/m{sup 3}, the establishment of a national radon action plan, and a more comprehensive regulation of radon protection at workplaces and public buildings. The radon action plan shall contain strategies and measures regarding for example the estimation of the distribution of indoor radon concentrations, the mapping of radon, the radon risk communication strategy, the assignment of responsibilities, and regular reviews of the action plan. The new EU-BSS often requires only the establishment of strategies and the specification of measures, leaving the precise content of the strategies and measures to the member states. This gives the member states flexibility for the implementation of the EU-BSS into national legislation and allows to account for specific national experiences and circumstances. This contribution discusses and evaluates - based on the existing regulations concerning radon protection in Austria - the effectiveness of different new measures and regulations with respect to reducing the radon risk in Austria. Furthermore, their feasibility and practicability in terms of administrative and financial effort will be discussed. Thus, efficient new measures which lead to an improvement of the current radon control system will be identified.

    This study investigates CO 2 emission reduction within the EU resulting from the Emissions Trading Scheme (ETS) up to 2030. This is performed by constructing a baseline scenario without the ETS and assessing the impacts of the ETS, as currently designed. The results indicate that the ETS will start to impact emissions primarily after 2025 due to the prevalence of a sizable allowance surplus. The impact of approved (i.e. back-loading and 2.2% linear reduction factor (LRF)) and proposed (i.e. market stability reserve (MSR)) policy interventions and the inclusion of aviation, could accelerate the exhaustion of surplus and increase emission reductions during the investigated period. However, these measures would be insufficient to restore the scarcity of allowances and the corresponding carbon price before the start of ETS Phase IV, and the effectiveness of EU-internal abatement cannot be guaranteed until 2023. The effectiveness could be further reduced in the case of the economic shocks or the exclusion of international aviation. To restore the scarcity of allowances, other reform options are necessary. This paper extends the reasoning for the early removal of the back-loaded 900 Mtonne allowances by 2020 and broadening the scope of ETS to other sectors with potential high demand for allowances. - Highlights: • Quantification of CO 2 emission abatement in the EU resulting from the ETS up to 2030. • The impact of policy interventions and the inclusion of aviation is quantified. • The effectiveness of EU ETS in EU-internal abatement is limited until 2023

    From 2003-2006, an EU network project ‘Sustaining Animal Health and Food Safety in Organic Farming‘ (SAFO), was carried out with 26 partners from 20 EU-countries and 4 related partners from 4 candidate or new member states. The focus was the integration of animal health and welfare issues...... in organic farming with food safety aspects. Four very consistent conclusions became apparent: 1) The climatic, physical and socio-economic conditions vary considerably throughout Europe, leading to different livestock farming systems. This limits the possibility for technology transfer between regions...

  13. New opportunities for EU projects at CERN

    2009-01-01

    In July 2009 the European Commission (EC) finalised how it will spend research funding for 2010, within its Framework Programme 7 (FP7). On 31 July the EC is expected to publish new calls for European project proposals, many of which are relevant to CERN. In the first two and a half years of Framework Programme 7 (2007-2013), CERN has been very successful – the Organization is participating in around 30 EU projects, with total EC contribution of nearly 35 million Euros. The now finalised 2010 Work Programmes for FP7 outline how the EC will allocate budgets within each research field. From these Work Programmes, a series of calls for proposals are published so researchers can apply for targeted funding within given deadlines. The first calls are expected to be launched on 31 July and closed later in the year. The web-site of the CERN EU Projects Office contains a list of all new calls of potential interest to CERN, as well as the relevant Work Programmes and Guide for A...

    Since the last SOFT conference held in Helsinki in 2002, substantial progress has been made in the EU R and D on the divertor components. A number of activities have been completed and new ones have been launched. The present paper gives an update of the works carried out by the EU Participating Team in support of the development of the divertor, which is one of the most challenging components of the next-step ITER machine. The following topics are covered: (1) the further development and consolidation of suitable technologies for the production of high heat-flux components, which culminated with the successful manufacturing and testing of a full-scale vertical target prototype; (2) the completion of the post-irradiation testing of divertor mock-ups and samples; (3) the preparation for the hydraulic and assembly tests of a complete set of full-scale divertor components; (4) the on-going R and D on the definition of workable acceptance criteria for the procurement of ITER high heat-flux components; (5) the activities in support of the divertor design

    Full Text Available One of the important area of international taxes is transfer pricing. Transfer price is a price set by a taxpayer when selling to, buying from, or sharing resources with a related (associated person. The tran­sac­tions between these persons should be assessed at their arm’s length price in according the arm’s length principle – international accepted standard – as the price which would have been agreed between unrelated parties in free market conditions. This paper is focused on the tranfer pricing rules used in particular EU Member States so as if EU Member States apply the arm’s length principle, define the related persons, apply recommendations of the OECD Guidelines, use the transfer pricing methods, require TP Documentation, exercise specific transfer pricing audit or impose specific penalties and apply APAs. Transfer pricing rules should prevent taxpayers from shifting income to related person organized in tax havens or in countries where they enjoy some special tax benefit.

    As a basis for the design and development of molten salt mixtures, thermodynamic calculations of the phase diagrams and thermodynamic properties were carried out on the EuBr 2 unary and LiBr-EuBr 2 and NaBr-EuBr 2 binary systems over a wide temperature and composition range, respectively. The Gibbs energy of EuBr 2 was evaluated using an independent polynomial to fit the experimental heat capacity, the thermodynamic parameters for each phase in the LiBr-EuBr 2 and NaBr-EuBr 2 systems were optimized by using available experimental information on phase diagrams. A regular substitutional solution model for the liquid phase and Neumann-Kopp rule for the stoichiometric compound LiEu 2 Br 5 were adopted to reproduce the experimental data with reasonable excess Gibbs energy. Comparisons between the calculated phase diagrams and thermodynamic quantities show that all reliable experimental information is satisfactorily accounted for by the present thermodynamic description. Some thermodynamic properties were predicted to check the suitability of the present calculation.

    would lead us closer towards a common European Administrative Space. However, so far such EU initiatives have left many questions unanswered regarding the supervision and financing of CADR schemes, as well as the administrative issues about the purely internal harmonization of “administrative” CADR practices in Member States. An example of the substantial administrative dilemmas in CADR practices, mostly in the field of universal services, can be recognized in existing CADR systems in selected EU countries, e.g. Slovenia and Croatia.

  19. Analysis of national allocation plans for the EU ETS

    The EU ETS is a Community-wide scheme established by Directive 2003/87/EC for trading allowances to cover the emissions of greenhouse gases from permitted installations. The first phase of the EU ETS runs from 1 January 2005 to 31 December 2007. Each Member State must develop a National Allocation Plan for the first phase stating: the total quantity of allowances that the Member State intends to issue during that phase; and how it proposes to distribute those allowances among the installations which are subject to the scheme In this paper twelve of the national allocation plans have been analysed and compared to the criteria stated in the EU Directive. The twelve allocation plans analysed are: the Austrian, the Danish, the Finnish, the German, the Irish, the Lithuanian, the Luxembourg, the Dutch, the Swedish, the British and the draft Flemish (Belgium) and Portuguese. Generally most countries have allocated generously to the trading sector. The allocation has often been based on future needs. For most sectors the allocation is higher than current emissions. Many countries will have to make large reductions in the non-trading sector and/or buy credits through JI- and CDM-projects in order to fulfil their commitment according to the EU burden sharing agreement of the Kyoto Protocol. In many of the allocation plans the emission reducing measures in the non-trading sector is poorly described and the credibility of the measures are hard to determine. Two sectors have been analysed in more detail, the energy and the mineral oil refining sectors. Figures presenting allocation vs. current emissions for those sectors are given for those countries where data was available in the allocation plan. The energy sector has been considered to have the best possibilities to pass on costs for the allowances to the consumers and hence the allocation to this sector is often more restricted than the allocation to other sectors. The mineral oil refining sector is more exposed to

    Up to now, orchestrating the coexistence of Eu 2+ and Eu 3+ activators in a single host lattice has been an extremely difficult task, especially for the appearance of the characteristic emission of Eu 2+ and Eu 3+ in order to generate white light. Nevertheless, here we demonstrate a new Eu 2+ /Eu 3+ coactivated SrAl 3 BO 7 nanocrystalline phosphor with abundant and excellent multichannel luminescence properties. A series of Eu 2+ /Eu 3+ coactivated SrAl 3 BO 7 nanocrystalline phosphors were prepared through a Pechini-type sol-gel method followed by a reduction process. With excitation of UV/NUV light, the prepared SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphors show not only the characteristic f-f transitions of Eu 3+ ion ( 5 D J → 7 F J,J' , J, J' = 0-3), but also the 5d → 4f transitions of Eu 2+ ion with comparable intensity from 400 to 700 nm in the whole visible spectral region. The luminescence color of the SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor can be tuned from blue, blue-green, white, and orange to orange-red by changing the excitation wavelength, the overall doping concentration of europium ions (Eu 2+ , Eu 3+ ), and the relative ratio of Eu 2+ to Eu 3+ ions to some extent. A single-phase white-light emission has been realized in SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor. The obtained SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor has potential application in the area of NUV white-light-emitting diodes.

  1. Negative pressure driven valence instability of Eu in cubic Eu0.4La0.6Pd3

    We report the change in the valency of Eu-ions in the binary intermetallic cubic compound EuPd 3 induced by La doping at rare-earth sites. Doping of La generates negative chemical pressure in the lattice, resulting in a significant increase of the lattice parameter without altering the simple-cubic structure of the compound. Results of dc-magnetic measurements suggest that this increase in the lattice parameter is associated with the valence transition of Eu-ions from Eu 3+ to a mixed-valent state. As Eu 2+ -ions possess a large magnetic moment, this valence transition significantly modifies the magnetic behavior of the compound. In contrast to introducing boron at the vacant body center site of the unit cell to change the valency of Eu-ions, as in the case of EuPd 3 B, our results suggest it can also be altered by doping a rare-earth ion of larger size at the lattice site of Eu in EuPd 3 .

    Thin films of Eu 2+ /Er 3+ codoped barium strontium silicate were deposited on a thermal oxide Si substrate by magnetron sputtering. Optical properties suggest that after a rapid annealing process, these films can lead to efficient Er 3+ emission at 1.54 μm with a lifetime of about 7.9 ms. Intense 1.54-μm light emission was achieved under broad ultraviolet light excitation through efficient energy transfer from Eu 2+ to Er 3+ . These results indicate that the Eu 2+ /Er 3+ thin films have potential applications as low cost and compact erbium doped waveguide amplifiers pumped by LEDs. - Highlights: • The Er 0.07 Eu 0.14 Sr 1.14 Ba 0.79 SiO 4 films are fabricated by magnetron sputtering. • Efficient energy transfer from Eu 2+ to Er 3+ ions by the dipole–dipole interaction. • Intense 1.54 μm emission is achieved under broad excitation spectrum. • The films have potential applications as low cost and compact EDWAs

    With regard to phosphor thermometry, the materials Y{sub 3}Al{sub 5}O{sub 12}:Eu (YAG:Eu) and YAlO{sub 3}:Eu (YAP:Eu) were synthesised and characterised in order to substitute the commonly used thermographic phosphor Y{sub 2}O{sub 3}:Eu, whose temperature sensitive luminescence lifetime exhibits a strong and most often undesirable cross-sensitivity to the oxygen concentration of the surrounding gas phase. The synthesis is outlined in detail and the crystallographic structure was characterised by X-ray diffraction. In a second step, the luminescence properties following pulsed UV laser excitation were determined. In this context, the emission spectra and the temperature lifetime characteristics were monitored. For Y{sub 3}Al{sub 5}O{sub 12}:Eu and YAlO{sub 3}:Eu, temperature sensitive ranges of 1000 K–1470 K and 850 K–1300 K were identified. Contrary to Y{sub 2}O{sub 3}:Eu, both materials do show much lower cross-sensitivities to the oxygen concentration of the surrounding gas phase. - Highlights: ► Y{sub 3}Al{sub 5}O{sub 12}:Eu and YAlO{sub 3}:Eu were synthesised and characterised. ► The synthesis is outlined and the crystallographic structure was characterised. ► Emission spectra and the temperature lifetime characteristics were monitored. ► Compared to Y{sub 2}O{sub 3}:Eu lower sensitivities to the oxyg. conc. of the gas phase emerged.

    This third volume of EU Energy Law and Policy Issues presents an overview of some of the most recent developments taking place in the EU energy sector at a time when the Third Energy Package is likely to be or has been implemented in the EU Member States. In this respect, the reader will find a number of contributions which offer detailed and critical views on some of the main issues tackled by the Third Energy Package. Aside from this, the relationship between sector specific regulation and the rules of general competition law is examined in the second section of the book. This part also contains particular contributions on access regimes in gas and electricity markets as well as an innovating analysis on the methods for allocating allowances under the EU Emissions trading scheme and the interaction of such methods with EU state aid rules. Just like the previous volumes of the book, section III offers a deep insight into the external aspects of EU energy policy. Accordingly, the role of the Lisbon Treaty in promoting EU energy policy in the international arena is scrutinized in addition to the most recent evolutions on the topical issue of the Energy Charter Treaty. This section is completed with a daring contribution about the need to adopt a comprehensive theory of legal harmonization between the EU and third partners, which is presented using the specific case of the EU-Russia Energy Dialogue. Last but not least, some fundamental issues regarding the environmental aspects of EU Energy policy undergo an in-depth study in the final section of the book. Not only is the legal regime of energy efficiency in energy-related products examined, but also the issue of carbon constraining policies under WTO law. Finally, the electricity's industry viewpoint on the 2020 targets rounds off this third volume of EU Energy Law and Policy Issues with judicious comments.

    Pyrochlore-type Eu{sub 2}Ta{sub 2}(O,N){sub 7+δ} phases were prepared by reaction of ammonia with an amorphous europium tantalum oxide precursor. {sup 151}Eu Moessbauer and EPR spectroscopy as well as magnetic susceptibility measurements point to the presence of exclusively Eu{sup 3+}. For phase-pure samples (X-ray powder diffraction), the nitrogen content varies between 1.0 and 1.8 wt %, leading to compositions in the range Eu{sub 2}Ta{sub 2}O{sub 7.1}N{sub 0.6} - Eu{sub 2}Ta{sub 2}O{sub 6.5}N{sub 1.0}. Pyrochlore-type phases are structurally derived from the fluorite type with 1/8 of the anions missing, resulting in an ideal composition A{sub 2}B{sub 2}X{sub 7}. In Eu{sub 2}Ta{sub 2}(O,N){sub 7+δ} the excess anions partly occupy these vacancies. The prepared phases are colorless with a direct optical bandgap of 4.3 eV and they show the typical Van Vleck paramagnetic behavior known for trivalent Eu atoms.

  8. Resonant TMR inversion in LiF/EuS based spin-filter tunnel junctions

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available Resonant tunneling can lead to inverse tunnel magnetoresistance when impurity levels rather than direct tunneling dominate the transport process. We fabricated hybrid magnetic tunnel junctions of CoFe/LiF/EuS/Ti, with an epitaxial LiF energy barrier joined with a polycrystalline EuS spin-filter barrier. Due to the water solubility of LiF, the devices were fully packaged in situ. The devices showed sizeable positive TMR up to 16% at low bias voltages but clearly inverted TMR at higher bias voltages. The TMR inversion depends sensitively on the thickness of LiF, and the tendency of inversion disappears when LiF gets thick enough and recovers its intrinsic properties.

    Nilsson, Mats

    2007-01-01

    The EU Green Paper on energy efficiency calls for action to decrease energy use and thus achieve increased competitiveness, fulfil the environmental targets and increase security of supply. In this comment, we examine the role the EU Commission suggest that energy efficiency, and policies supporting energy efficiency, takes. The policies and the suggestions are qualitatively elaborated upon in the light of the goal of a common European electricity market. We suggest that the rationales for the energy efficiency measures are weak, and that the suggested goals of increased competitiveness, environmental targets, and security of supply are best reached with the direct measures especially designed for each goal. Some of the energy efficiency measures may counter-act other direct policies. Further, The Green Paper measures may prove detrimental to the European Electricity market insofar as the policies suggested could lead to a policy fatigue among the electricity consumers

    The electron cyclotron (EC) heating and current drive (H (and) CD) system of ITER will deliver 20 MW/CW in the plasma at 170 GHz for H (and) CD in addition to 2.5 MW/3 s at 120 GHz for plasma start-up. The EC system is composed of power supplies (PS), up to 24 H (and) CD gyrotrons (1 to 2 MW tubes), 3 start-up gyrotrons (1 MW tubes), 24 transmission lines and two sets of launching antennas: equatorial (EL) and upper (UL) launchers. Under the present ITER procurement package the EU is responsible for one third of the H (and) CD 170 GHz gyrotrons, all PSs associated with the H (and) CD system, and the whole set (4) of upper launchers. In all areas of participation, the EU EC partnership (coordinated by the European Fusion Development Association - EFDA) aims toward advancing the technology of each of these subsystems. For example, procurement of Pulse Step Modulator (PSM) HVPS is under consideration, which might have equivalent costs to the present ITER design (thyristor HVPS and HV series switch), but with an increased flexibility in operation and variation in the EC power waveform. The EU is at the forefront in gyrotron research and is developing a 2 MW CW 170 GHz coaxial cavity gyrotron offering an increase in output power while maintaining moderate power densities in the gyrotron cavity and collector. THALES R in collaboration with its EFDA partners (FZK, CRPP, TEKES) is manufacturing a series of prototype tubes in three phases of typically 1 s, 100 s and then CW pulse capacity (∼ 20 10 ). A 2 MW, CW gyrotron test facility is being built at CRPP that will be used to develop the 2 MW coaxial tube, in addition to testing various components required by the EC system. EFDA has undertaken a parallel development of two launcher options: front (FS) and remote (RS) steering, with the aim of providing an optimum launcher for ITER weighing EC physics aspects and operation reliability. The FS launcher (ITER reference design) offers a significant enhancement in physics

    In phosphor area today top priority is the replacement of the high performance but very expensive rare earth activated phosphors with cheaper materials. This essentially means replacing the rare earth ions with transition metal ions or post transition ions. Now a day's phosphors are used in various fields. After World War II, the advances in the optical spectroscopy of solids, especially those of transition metals ions help to evolve research on phosphor and solid state luminescence. In 1960 efficient rare earth activated phosphors were developed for use in color TV (Tb 3+ green, Eu 3+ red, and Dy 3+ yellow). In 1970 tricolor lamp was introduced blue emission from Ce 3+ + Tb 3+ pair was used in tricolor lamps. At present combination of halo phosphor and tri-band phosphor blend is used in many lamp as a compromise between performance, phosphor cost and the lamp making Cost. Thermo luminescence of 0.5 Gy X-ray irradiated BAM.Eu has been studied. The irradiated phosphor has been studied for its TL dosimetric properties one week after irradiation and after 100 weeks of storage. Interesting TL results are reported in the present paper. Heating rate used in the present experiment is 6.6 deg C/Sec. The following two figures are on TL recorded 100 weeks after irradiation and TL recorded after 235 weeks of storage. Before storage for 100 weeks the TL glow curve with a hump around 180 deg C followed by a peak at 273 deg C. After storage for 100 weeks the TL pattern changes entirely. i.e. the composite TL peak structure emerged as two well resolved peaks and with slightly higher TL peak temperatures at 215 deg C and 300 deg C. Normally after storage for 100 weeks the peak at 190 deg C reduces in its intensity or disappears in some cases, instead of that the peak appears at 215 deg C as well resolved peak and its intensity is almost comparable to that of 300 deg C peak. Since the TL phenomenon observed is interesting the two well resolved, isolated, high intensity peaks

    It is the ambition of the EU to reduce the number of killed and seriously injured on the roads over time. It has turned out that, especially in relation to serious injuries, there is still a significant knowledge gap on how to reduce these numbers in the EU. The Commission is therefore committed to

  17. Selective separation of Eu3+ using polymer-enhanced ultrafiltration

    A process to selectively remove 241 Am from liquid radioactive waste was investigated as an actinide separation method applicable to Hanford and other waste sites. The experimental procedures involved removal of Eu, a nonradioactive surrogate for Am, from aqueous solutions at pH 5 using organic polymers in conjunction with ultrafiltration. Commercially available polyacrylic acid (60,000 MW) and Pacific Northwest Laboratory's (PNL) synthesized E3 copolymer (∼10,000 MW) were tested. Test solutions containing 10 μg/mL of Eu were dosed vath each polymer at various concentrations in order to bind Eu (i.e., by complexation and/or cation exchange) for subsequent rejection by an ultrafiltration coupon. Test solutions were filtered with and without polymer to determine if enhanced Eu separation could be achieved from polymer treatment. Both polymers significantly increased Eu removal. Optimum concentrations were 20 μg/mL of polyacrylic acid and 100 μg/mL of E3 for 100% Eu rejection by the Amicon PM10 membrane at 55 psi. In addition to enhancement of removal, the polymers selectively bound Eu over Na, suggesting that selective separation of Eu was possible. This suggests that polymer-enhanced ultrafiltration is a potential process for separation of 241 Am from Hanford tank waste, further investigation of binding agents and membranes effective under very alkaline and high ionic strength is warranted. This process also has potential applications for selective separation of toxic metals from industrial process streams

  20. EU trade in the time of financial crisis

    Full Text Available The paper is focused on the European Union (EU trade and trade policy in the time of global financial and economic crisis. The analysis of the EU exports and imports points out that the financial crisis has had a negative impact on the intra as well as on the extra-EU trade in the period 2007-2009, but differences among the EU member states have existed. Although the EU tries to support trade development in the world and remove barriers to trade, some protectionist tendencies were recorded in the time of the economic crisis. The last part of the paper gives emphasis to the EU trade policy and some trade measures which have been taken in the EU and its member states to support trade development or vice versa, to protect domestic industries. The results of the analysis show that, although some protectionist tendencies have been recorded both in extra and intra-EU trade, trade relations which are provided among member states are of significant importance all the time.
