    2004-01-01

    The ClearPET TM project is proposed by working groups of the Crystal Clear Collaboration (CCC) to develop a 2/sup nd/ generation high performance small animal positron emission tomograph (PET). High sensitivity and high spatial resolution is foreseen for the ClearPET TM camera by using a phoswich arrangement combining mixed lutetium yttrium aluminum perovskite (LuYAP:Ce) and lutetium oxyorthosilicate (LSO) scintillating crystals. Design optimizations for the first photomultiplier tube (PMT) based ClearPET camera are done with a Monte-Carlo simulation package implemented on GEANT3 (CERN, Geneva, Switzerland). A dual-head prototype has been built to test the frontend electronics and was used to validate the implementation of the GEANT3 simulation tool. Multiple simulations were performed following the experimental protocols to measure the intrinsic resolution and the sensitivity profile in axial and radial direction. Including a mean energy resolution of about 27.0% the simulated intrinsic resolution is about (...

    Full Text Available This paper presents an investigation of electroless nickel plating on PerFactoryTM rapid prototype model built on PerFactoryTM R05 material. PerFactoryTM R05 is acrylic based photo sensitive resin. It is a popular material in rapid prototyping using PerFactoryTM method which employs addictive manufacturing technique to build prototypes for visual inspection, assembly etc. Metallization of such a prototype can extend the application envelop of the rapid prototyping technique as they can be used in many functional applications. Unlike the electroless nickel plating on metal substrate, the process on acrylic resin substrate is not auto-catalytic. Hence, etching and activation are necessary for initiating the process. The final coating is then investigated using scanning electron microscope (SEM together with energy dispersive spectroscopy (EDS and x-ray diffraction (XRD analysis to identify the morphology and structure of the coating. The SEM & EDS analysis on surface and chemical composition of model surface after each preliminary surface treatment are also presented. Finally the layer is tested on Vickers micro hardness tester.

  6. Development of a static bioactive stent prototype and dynamic aneurysm-on-a-chip(TM) model for the treatment of aneurysms

    Science.gov (United States)

    Reece, Lisa M.

    Aneurysms are pockets of blood that collect outside blood vessel walls forming dilatations and leaving arterial walls very prone to rupture. Current treatments include: (1) clipping, and (2) coil embolization, including stent-assisted coiling. While these procedures can be effective, it would be advantageous to design a biologically active stent, modified with magnetic stent coatings, allowing cells to be manipulated to heal the arterial lining. Further, velocity, pressure, and wall shear stresses aid in the disease development of aneurysmal growth, but the shear force mechanisms effecting wound closure is elusive. Due to these factors, there is a definite need to cultivate a new stent device that will aid in healing an aneurysm in situ. To this end, a static bioactive stent device was synthesized. Additionally, to study aneurysm pathogenesis, a lab-on-a-chip device (a dynamic stent device) is the key to discovering the underlying mechanisms of these lesions. A first step to the reality of a true bioactive stent involves the study of cells that can be tested against the biomaterials that constitute the stent itself. The second step is to test particles/cells in a microfluidic environment. Therefore, biocompatability data was collected against PDMS, bacterial nanocellulose (BNC), and magnetic bacterial nanocellulose (MBNC). Preliminary static bioactive stents were synthesized whereby BNC was grown to cover standard nitinol stents. In an offshoot of the original research, a two-dimensional microfluidic model, the Aneurysm-on-a-ChipTM (AOC), was the logical answer to study particle flow within an aneurysm "sac" - this was the dynamic bioactive stent device. The AOC apparatus can track particles/cells when it is coupled to a particle image velocimetry software (PIV) package. The AOC fluid flow was visualized using standard microscopy techniques with commercial microparticles/cells. Movies were taken during fluid flow experiments and PIV was utilized to monitor.

  8. The ClearPET project

    International Nuclear Information System (INIS)

    The Crystal Clear Collaboration has designed and is building a high-resolution small animal PET scanner. The design is based on the use of the Hamamatsu R7600-M64 multi-anode photomultiplier tube and a LSO/LuYAP phoswich matrix with one to one coupling between the crystals and the photo-detector. The complete system will have 80 PM tubes in four rings with an inner diameter of 137 mm and an axial field of view of 110 mm. The PM pulses are digitized by free-running ADCs and digital data processing determines the gamma energy, the phoswich layer and even the pulse arrival time. Single gamma interactions are recorded and coincidences are found by software. The gantry allows rotation of the detector modules around the field of view. Simulations, and measurements a 2x4 module test set-up predict a spatial resolution of 1.5 mm in the centre of the field of view and a sensitivity of 5.9% for a point source in the centre of the field of view

    This report presents studies oriented to optimize the image quality of the small animal PET: Clear- PET. Certain figures of merit (FOM) were used to assess a quantitative value of the contrast and delectability of lesions. The optimization was carried out modifying some of the parameters in the reconstruction software of the scanner, imaging a mini-Derenzo phantom and a cylinder phantom with background activity and two hot spheres. Specifically, it was evaluated the incidence of the inter-update Metz filter (IMF) inside the iterative reconstruction algorithm 3D OSEM. The data acquisition was simulated using the GAMOS framework (Monte Carlo simulation). Integrating GAMOS output with the reconstruction software of the scanner was an additional novelty of this work, to achieve this, data sets were written with the list-mode format (LMF) of ClearPET. In order to verify the optimum values obtained, we foresee to make real acquisitions in the ClearPET of CIEMAT. (Author) 17 refs.

    For the purpose of obtaining data on 161Er, 163Er and 165Er nuclear level properties the 161Tm→161Er, 163Tm→163Er, 165Tm→165Er decay is investigated. Radioactive isotopes sup(161, 163, 165)Tm have been obtained in the deep fission reaction at the tantalum target irradiation during 1-10 h by 660 MeV protons. The electron spectra of internal conversion have been investigated by beta spectrographs with constant magnetic field. Gamma radiation spectra have been measured by means of precision gamma spectrometers with Ge(Li) detectors. Measurement results in the gamma radiation energy range from 5 to 400 keV are tabulated. Gamma radiation and conversion electron energies and intensities are specified. 68 gamma transitions are related to 161Tm decay. For 67 of them multipolarity types are determined, for 20 - coefficients of multipolarity mixture. 47 gamma transitions have been found at the 163Tm decay. New gamma transitions with energies of 14.72(E1), 20.34(E2) and 35.05 KeV have been found out. Coefficients of multipolarity mixture are obtained for 18 gamma transitions. 82 gamma transitions have been found out at the 165Tm decay. 13 gamma transitions have been observed for the first time. 60 gamma transition multipolarities are determined. Coefficients of multipolarity mixture are calculated for 19 gamma transitions. Coefficients of multipolarity mixture are obtained from the intensity ratio of L1-, L2-, L3-, M1-, M2-, M3-lines

    Shelter structures on the moon, even in early phases of exploration, should incorporate lunar materials as much as possible. This Technical Memorandum details the design and construction of a prototype for a one-piece regolith bag unpressurized garage concept and a materials testing program to investigate six candidate fabrics to learn how they might perform in the lunar environment. The conceptualization was that a lightweight fabric form be launched from Earth and landed on the lunar surface to be robotically filled with raw lunar regolith. Regolith bag fabric candidates included: Vectran(TM), Nextel(TM), Gore PTFE Fabric(TM), Zylon(TM), Twaron(TM), and Nomex(TM). Tensile (including post radiation exposure), fold, abrasion, and hypervelocity impact testing were performed under ambient conditions, and also performed under cold and elevated temperatures. In some cases, Johnson Space Center lunar simulant (JSC-1) was used in conjunction with testing. A series of preliminary structures was constructed during final prototype design based on the principles of the classic masonry arch. The prototype was constructed of Kevlar(TM) and filled with vermiculite. The structure is free-standing, but has not yet been load tested. Future plans would be to construct higher fidelity prototypes and to conduct appropriate tests of the structure.

    Shelter structures on the moon, even in early phases of exploration, should incorporate lunar materials as much as possible. We designed and constructed a prototype for a one-piece regolith-bag unpressurized garage concept, and, in parallel, we conducted a materials testing program to investigate six candidate fabrics to learn how they might perform in the lunar environment. In our concept, a lightweight fabric form is launched from Earth to be landed on the lunar surface and robotically filled with raw lunar regolith. In the materials testing program, regolith-bag fabric candidates included: Vectran(TM), Nextel(TM), Gore PTFE Fabric(TM), Zylon(TM), Twaron(TM), and Nomex(TM). Tensile (including post radiation exposure), fold, abrasion, and hypervelocity impact testing were performed under ambient conditions, and, within our current means, we also performed these tests under cold and elevated temperatures. In some cases, lunar simulant (JSC-1) was used in conjunction with testing. Our ambition is to continuously refine our testing to reach lunar environmental conditions to the extent possible. A series of preliminary structures were constructed during design of the final prototype. Design is based on the principles of the classic masonry arch. The prototype was constructed of Kevlar(TM) and filled with vermiculite (fairly close to the weight of lunar regolith on the moon). The structure is free-standing, but has not yet been load tested. Our plan for the future would be to construct higher fidelity mockups with each iteration, and to conduct appropriate tests of the structure.

    2016-01-01

    In this book, the authors describe the findings derived from interaction and cooperation between scientific actors employing diverse practices. They reflect on distinct prototyping concepts and examine the transformation of development culture in their fusion to hybrid approaches and solutions. The products of tomorrow are going to be multifunctional, interactive systems – and already are to some degree today. Collaboration across multiple disciplines is the only way to grasp their complexity in design concepts. This underscores the importance of reconsidering the prototyping process for the development of these systems, particularly in transdisciplinary research teams. “Rethinking Prototyping – new hybrid concepts for prototyping” was a transdisciplinary project that took up this challenge. The aim of this programmatic rethinking was to come up with a general concept of prototyping by combining innovative prototyping concepts, which had been researched and developed in three sub-projects: “Hybrid P...

    2004-07-01

    This final report for the Swiss Federal Office of Energy (SFOE) presents the results of investigations made on the development of an energy-efficient electric motor. The aim of the prototype 'Eco-Motor' project was the development of a winding technique and the optimisation of the design of the stator. Various winding techniques (toroid winding, core winding, coil winding) were examined and used in the realisation of prototype 'Eco-Motors' for a nominal voltage of 230 V a.c. The designs were evaluated in both a simulation (FEMM) and as well as in the test facilities at the College of Engineering and Architecture in Lucerne, Switzerland. The measured data of the 'Eco-Motor' were then compared with a standard asynchronous motor. The 'Eco-Motor' with a toroid winding had the best efficiency. At low loads, all 'Eco-Motor' prototypes have a higher efficiency than asynchronous motors. On the other hand, none of the 'Eco-Motors' have yet reached the nominal power of 250 W. The developers state, however, that with a few adjustments this should pose no problems.

    A small animal positron emission tomograph, ClearPET, is under development by the Crystal Clear Collaboration at CERN. ClearPET, a detector with Depth Of Interaction (DOI) determination capability is based on LSO:Ce and (Lu //0//.//7-Y//0//.//3)AlO//3:Ce ((Lu-Y)AP:Ce or LuYAP) scintillation crystals assembled in two-layer matrix with PMT readout. The key point of the ClearPET challenge was the development of the mass production technology of Lu-based scintillation crystals with perovskite structure. The LuYAP scintillation crystal has been proposed several years ago but its mass production technology could only be managed now, through tremendous efforts of the Crystal Clear Collaboration and of its industrial partners. Crystal ingots 18-25mm in diameter and 170-210mm in length are available now. In this paper, we discuss the results of the crystal mass production technology development and its application in detecting modules.

  2. Prototyping a Smart City

    Korsgaard, Henrik; Brynskov, Martin

    In this paper, we argue that by approaching the so-called Smart City as a design challenge, and an interaction design perspective, it is possible to both uncover existing challenges in the interplay between people, technology and society, as well as prototype possible futures. We present a case...... in which we exposed data about the online communication between the citizens and the municipality on a highly visible media facade, while at the same time prototyped a tool that enabled citizens to report ‘bugs’ within the city....

    The LUX (Large Underground Xenon) detector is a two-phase xenon Time Projection Chamber (TPC) designed to search for WIMP-nucleon dark matter interactions. As with all noble element detectors, continuous purification of the detector medium is essential to produce a large ($>$1ms) electron lifetime; this is necessary for efficient measurement of the electron signal which in turn is essential for achieving robust discrimination of signal from background events. In this paper we describe the development of a novel purification system deployed in a prototype detector. The results from the operation of this prototype indicated heat exchange with an efficiency above 94% up to a flow rate of 42 slpm, allowing for an electron drift length greater than 1 meter to be achieved in approximately two days and sustained for the duration of the testing period.

    2009-05-01

    The MITRE Sensor Layer Prototype is an initial design effort to enable every sensor to help create new capabilities through collaborative data sharing. By making both upstream (raw) and downstream (processed) sensor data visible, users can access the specific level, type, and quantities of data needed to create new data products that were never anticipated by the original designers of the individual sensors. The major characteristic that sets sensor data services apart from typical enterprise services is the volume (on the order of multiple terabytes) of raw data that can be generated by most sensors. Traditional tightly coupled processing approaches extract pre-determined information from the incoming raw sensor data, format it, and send it to predetermined users. The community is rapidly reaching the conclusion that tightly coupled sensor processing loses too much potentially critical information.1 Hence upstream (raw and partially processed) data must be extracted, rapidly archived, and advertised to the enterprise for unanticipated uses. The authors believe layered sensing net-centric integration can be achieved through a standardize-encapsulate-syndicateaggregate- manipulate-process paradigm. The Sensor Layer Prototype's technical approach focuses on implementing this proof of concept framework to make sensor data visible, accessible and useful to the enterprise. To achieve this, a "raw" data tap between physical transducers associated with sensor arrays and the embedded sensor signal processing hardware and software has been exploited. Second, we encapsulate and expose both raw and partially processed data to the enterprise within the context of a service-oriented architecture. Third, we advertise the presence of multiple types, and multiple layers of data through geographic-enabled Really Simple Syndication (GeoRSS) services. These GeoRSS feeds are aggregated, manipulated, and filtered by a feed aggregator. After filtering these feeds to bring just the type

    CERN Multimedia

    OPAL was one of the four experiments installed at the LEP particle accelerator from 1989 - 2000. OPAL's central tracking system consists of (in order of increasing radius) a silicon microvertex detector, a vertex detector, a jet chamber, and z-chambers. All the tracking detectors work by observing the ionization of atoms by charged particles passing by: when the atoms are ionized, electrons are knocked out of their atomic orbitals, and are then able to move freely in the detector. These ionization electrons are detected in the dirfferent parts of the tracking system. This piece is a prototype of the jet chambers

  3. DataCollection Prototyping

    CERN Multimedia

    Beck, H.P.

    DataCollection is a subsystem of the Trigger, DAQ & DCS project responsible for the movement of event data from the ROS to the High Level Triggers. This includes data from Regions of Interest (RoIs) for Level 2, building complete events for the Event Filter and finally transferring accepted events to Mass Storage. It also handles passing the LVL1 RoI pointers and the allocation of Level 2 processors and load balancing of Event Building. During the last 18 months DataCollection has developed a common architecture for the hardware and software required. This involved a radical redesign integrating ideas from separate parts of earlier TDAQ work. An important milestone for this work, now achieved, has been to demonstrate this subsystem in the so-called Phase 2A Integrated Prototype. This prototype comprises the various TDAQ hardware and software components (ROSs, LVL2, etc.) under the control of the TDAQ Online software. The basic functionality has been demonstrated on small testbeds (~8-10 processing nodes)...

  8. Electrochemical reduction of Tm on Mg electrodes and co-reduction of Mg, Li and Tm on W electrodes

    International Nuclear Information System (INIS)

    The reduction process of Tm(III) ions was investigated in LiCl–KCl–MgCl2 melt on a W electrode and in LiCl–KCl melt on a Mg electrode at 753 K, respectively. On the W electrode, in LiCl–KCl–MgCl2 melt the reduction of Tm(III) ions was a two-step process: Tm(III) + e−1 → Tm(II) and yTm(II) + 2ye−1 + xMg → MgxTmy. The reduction process of Tm(III)/Tm(II) was not observed on the Mg electrode, and only two signals, related to Mg–Tm intermetallic compounds were observed, in the cyclic voltammogram and chronopotentiogram. Galvanostatic electrolysis was employed to prepare Mg–Li–Tm alloys on both W and Mg electrodes. The deposits were characterized by X-ray diffraction (XRD), optical microscopy (OM) and scanning electron microscopy (SEM). Mg24Tm5 and Mg2Tm phases were detected in the deposits. The effect of Tm addition on Mg–Li alloy was investigated via potentiodynamic polarization and OM at room temperature. The grain size of Mg–Li alloy becomes much smaller after addition of Tm element. The corrosion potentials of Mg–Li–Tm alloys shift toward a more positive direction than that of Mg–Li alloy

  10. UA1 prototype detector

    CERN Multimedia

    1980-01-01

    Prototype of UA1 central detector inside a plexi tube. The UA1 central detector was crucial to understanding the complex topology of proton-antiproton events. It played a most important role in identifying a handful of Ws and Zs among billions of collisions. The detector was a 6-chamber cylindrical assembly 5.8 m long and 2.3 m in diameter, the largest imaging drift chamber of its day. It recorded the tracks of charged particles curving in a 0.7 Tesla magnetic field, measuring their momentum, the sign of their electric charge and their rate of energy loss (dE/dx). Atoms in the argon-ethane gas mixture filling the chambers were ionised by the passage of charged particles. The electrons which were released drifted along an electric field shaped by field wires and were collected on sense wires. The geometrical arrangement of the 17000 field wires and 6125 sense wires allowed a spectacular 3-D interactive display of reconstructed physics events to be produced.

It was created in 1992 and has since been used in over 800 reservoir evaluations. The tool provides information on the feasibility of IOR processes based on reservoir parameters. PRIze{sup TM} makes predictions for chemical, gas injection and thermal IOR processes based on both vertical and horizontal wells. The program provides a uniform data entry screen that allows the user to input 42 average values of geological parameters, fluid properties and oil production mechanism information into a data file. The data can be used to provide a production forecast, and enable the user to establish, to a first order approximation, the economic viability of a given process.

  19. TM01 mode accelerating cavity optimization

    International Nuclear Information System (INIS)

    The cost of an accelerator depends greatly upon the effective use of rf power for particle acceleration. Before completing an accelerator design, an optimization of the accelerating cells relative to the effective shunt impedance should be made to measure the structure's efficiency in providing a high and effective acceleration of particles for a given rf power. Optimization of the accelerating cell resonant at f/sub r/ = 1350 MHz (TM01 mode) relative to the maximum effective shunt impedance ZT2 was performed at the Los Alamos Scientific Laboratory using the computer program SUPERFISH. The study was parametric; one parameter was changed while the others were held constant. Frequency adjustments were made by changing the cavity radius. Results presented in this report can be used to design similar cavities at different resonant frequencies or to design a more complicated cavity (TM02 mode) for the disk and washer structure

    Interband line pixel misregistrations were determined for the four MSS bands of the Mistassini, Ontario scene and multitemporal registration of LANDSAT-4 products were tested for two different geocoded scenes. Line and pixel misregistrations are tabulated as determined by the manual ground control points and the digital band to band correlation techniques. A method was developed for determining the spectral information content of TM images for forestry applications.

  3. Fast-prototyping of VLSI

    International Nuclear Information System (INIS)

    Fast-prototyping will be a reality in the very near future if both straightforward design methods and fast manufacturing facilities are available. This book focuses, first, on the motivation for fast-prototyping. Economic aspects and market considerations are analysed by European and Japanese companies. In the second chapter, new design methods are identified, mainly for full custom circuits. Of course, silicon compilers play a key role and the introduction of artificial intelligence techniques sheds a new light on the subject. At present, fast-prototyping on gate arrays or on standard cells is the most conventional technique and the third chapter updates the state-of-the art in this area. The fourth chapter concentrates specifically on the e-beam direct-writing for submicron IC technologies. In the fifth chapter, a strategic point in fast-prototyping, namely the test problem is addressed. The design for testability and the interface to the test equipment are mandatory to fulfill the test requirement for fast-prototyping. Finally, the last chapter deals with the subject of education when many people complain about the lack of use of fast-prototyping in higher education for VLSI

    The study demonstrates the possibility of using Tm:YAP laser radiation for the removing ceramic brackets. The amount of enamel loss and residual resin on teeth has been evaluated. A diode-pumped Tm:YAP microchip laser generating at wavelength 1.9 μm was used for the debonding process. The transmission and absorption measurement of the basic elements - bracket, adhesive resin, and enamel was analyzed to explain the source of the heat and bracket debonding. Quantitative measurements are made for visualizing enamel surface before and after a self-ligating bonding technique. Temperature rise observation during the debonding procedure - from 0.5 to 2 W power - has improved the accuracy of assessment. The results were evaluated by CCD camera and scanning electron microscope. From the measurements it is possible to conclude that continuously running small diode pumped Tm:YAP microchip laser having output power 1W can remove the ceramic bracket without enamel iatrogenic damage.

    2016-01-01

    We present a study of mono(benzene)TM and bis(benzene)TM systems, where TM={Mo,W}. We calculate the binding energies by quantum Monte Carlo (QMC) approaches and compare the results with other methods and available experiments. The orbitals for the determinantal part of each trial wave function were generated from several types of DFT in order to optimize for fixed-node errors. We estimate and compare the size of the fixed-node errors for both the Mo and W systems with regard to the electron density and degree of localization in these systems. For the W systems we provide benchmarking results of the binding energies, given that experimental data is not available.

  6. Cryogenic tests of the first two LHC quadrupole prototypes

    International Nuclear Information System (INIS)

    Two LHC (Large Hadron Collider) twin aperture quadrupole prototypes were constructed at CEA Saclay (a CERN-CEA collaboration agreement). Their main characteristics are: 3.05 m length, 56 mm coil aperture, 180 mm between the two apertures, 252 T/m nominal gradient at 15060 A. They have been tested and measured in the 1.8 K Saclay test facility in an horizontal cryostat. The magnets are instrumented in order to investigate their behaviour during cool-down, stand-by, powering and current ramping, quenching and warming-up. A summary of the cryogenic, mechanical, pressure and electrical measurements is presented. The quench protection heaters are efficient down to 3000 A. Losses during ramping up and down are reported.

  7. Fr-TM-align: a new protein structural alignment method based on fragment alignments and the TM-score

    Directory of Open Access Journals (Sweden)

    Skolnick Jeffrey

    2008-12-01

    Full Text Available Abstract Background Protein tertiary structure comparisons are employed in various fields of contemporary structural biology. Most structure comparison methods involve generation of an initial seed alignment, which is extended and/or refined to provide the best structural superposition between a pair of protein structures as assessed by a structure comparison metric. One such metric, the TM-score, was recently introduced to provide a combined structure quality measure of the coordinate root mean square deviation between a pair of structures and coverage. Using the TM-score, the TM-align structure alignment algorithm was developed that was often found to have better accuracy and coverage than the most commonly used structural alignment programs; however, there were a number of situations when this was not true. Results To further improve structure alignment quality, the Fr-TM-align algorithm has been developed where aligned fragment pairs are used to generate the initial seed alignments that are then refined using dynamic programming to maximize the TM-score. For the assessment of the structural alignment quality from Fr-TM-align in comparison to other programs such as CE and TM-align, we examined various alignment quality assessment scores such as PSI and TM-score. The assessment showed that the structural alignment quality from Fr-TM-align is better in comparison to both CE and TM-align. On average, the structural alignments generated using Fr-TM-align have a higher TM-score (~9% and coverage (~7% in comparison to those generated by TM-align. Fr-TM-align uses an exhaustive procedure to generate initial seed alignments. Hence, the algorithm is computationally more expensive than TM-align. Conclusion Fr-TM-align, a new algorithm that employs fragment alignment and assembly provides better structural alignments in comparison to TM-align.

    2004-07-01

    Many definitions of forgiveness currently exist in the literature. The current research adds to this discussion by utilizing a prototype approach to examine lay conceptions of forgiveness. A prototype approach involves categorizing objects or events in terms of their similarity to a good example, whereas a classical approach requires that there are essential elements that must be present. In Study 1, participants listed the features of forgiveness. Study 2 obtained centrality ratings for these features. In Studies 3 and 4, central features were found to be more salient in memory than peripheral features. Study 5 showed that feature centrality influenced participants' ratings of victims involved in hypothetical transgressions. Thus, the two criteria for demonstrating prototype structure (that participants find it meaningful to judge features in terms of their centrality and that centrality affects cognition) were met.

    This work focuses on investigating the electrochemical formation of Al–Tm and Al–Li–Tm alloys in LiCl–KCl–AlCl3–Tm2O3 melt on both W and Al electrodes. Thermodynamic calculation and electrochemical behavior of LiCl–KCl melt containing both AlCl3 and Tm2O3 showed that AlCl3 can chlorinate Tm2O3 to release Tm(III) ions. Three kinds of Al–Tm intermetallics at about −1.26, −1.32 and −1.43 V were detected by means of various electrochemical measurement techniques, i.e. cyclic voltammetry, square wave voltammetry and open circuit chronopotentiometry. Potentiostatic and galvanostatic electrolysis were carried out on Al and W electrodes to prepare Al–Tm and Al–Li–Tm alloys, respectively. The composition of Al–Li–Tm alloys was analyzed by inductive coupled plasma atomic emission spectrometer (ICP-AES)

  14. ACR-1000TM - advanced Candu reactor design

    International Nuclear Information System (INIS)

    Atomic Energy of Canada Limited (AECL) has developed the Advanced CANDU ReactorTM- 1000 (ACR-1000TM) as an evolutionary advancement of the current CANDU 6TM reactor. This evolutionary advancement is based on AECL's in-depth knowledge of CANDU structures, systems, components and materials, gained during 50 years of continuous construction, engineering and commissioning, as well as on the experience and feedback received from operators of CANDU plants. The ACR design retains the proven strengths and features of CANDU reactors, while incorporating innovations and state-of-the-art technology. These innovations improve economics, inherent safety characteristics, and performance, while retaining the proven benefits of the CANDU family of nuclear power plants. The Canadian nuclear reactor design evolution that has reached today's stage represented by the ACR-1000, has a long history dating back to the early 1950's. In this regard, Canada is in a unique situation, shared only by a very few other countries, where original nuclear power technology has been invented and further developed. The ACR design has been reviewed by domestic and international regulatory bodies, and has been given a positive regulatory opinion about its licensability. The Canadian regulator, the Canadian Nuclear Safety Commission (CNSC) completed the Phase 1 and Phase 2 pre-project design reviews in December 2008 and August 2009, respectively, and concluded that there are no fundamental barriers to licensing the ACR-1000 design in Canada. The final stage of the ACR-1000 design is currently underway and will be completed by fall of 2011, along with the final elements of the safety analyses and probabilistic safety analyses supporting the finalized design. The generic Preliminary Safety Analysis Report (PSAR) for the ACR-1000 was completed in September 2009. The PSAR demonstrates ACR-1000 safety case and compliance with Canadian and international regulatory requirements and expectations. (authors)

  16. Structural and functional importance of transmembrane domain 3 (TM3) in the aspartate:alanine antiporter AspT: topology and function of the residues of TM3 and oligomerization of AspT.

    2009-04-01

    AspT, the aspartate:alanine antiporter of Tetragenococcus halophilus, a membrane protein of 543 amino acids with 10 putative transmembrane (TM) helices, is the prototype of the aspartate:alanine exchanger (AAE) family of transporters. Because TM3 (isoleucine 64 to methionine 85) has many amino acid residues that are conserved among members of the AAE family and because TM3 contains two charged residues and four polar residues, it is thought to be located near (or to form part of) the substrate translocation pathway that includes the binding site for the substrates. To elucidate the role of TM3 in the transport process, we carried out cysteine-scanning mutagenesis. The substitutions of tyrosine 75 and serine 84 had the strongest inhibitory effects on transport (initial rates of l-aspartate transport were below 15% of the rate for cysteine-less AspT). Considerable but less-marked effects were observed upon the replacement of methionine 70, phenylalanine 71, glycine 74, arginine 76, serine 83, and methionine 85 (initial rates between 15% and 30% of the rate for cysteine-less AspT). Introduced cysteine residues at the cytoplasmic half of TM3 could be labeled with Oregon green maleimide (OGM), whereas cysteines close to the periplasmic half (residues 64 to 75) were not labeled. These results suggest that TM3 has a hydrophobic core on the periplasmic half and that hydrophilic residues on the cytoplasmic half of TM3 participate in the formation of an aqueous cavity in membranes. Furthermore, the presence of l-aspartate protected the cysteine introduced at glycine 62 against a reaction with OGM. In contrast, l-aspartate stimulated the reactivity of the cysteine introduced at proline 79 with OGM. These results demonstrate that TM3 undergoes l-aspartate-induced conformational alterations. In addition, nonreducing sodium dodecyl sulfate-polyacrylamide gel electrophoresis analyses and a glutaraldehyde cross-linking assay suggest that functional AspT forms homo-oligomers as a

    The introduction of a power exchange in France is a direct response to the opening up of the European electricity markets. Powernext SA is a Multilateral Trading Facility in charge of managing the French power exchange through an optional and anonymous organised exchange offering: - Day-ahead contracts for the management of volume risk on Powernext Day-AheadTM since 21 November 2001, - Medium term contracts for the management of price risk on Powernext FuturesTM since 18 June 2004. This document is the 2004 activity report of Powernext SA, it presents the key figures of the power market and of Powernext in 2004: - Increasing volumes: Powernext Day-AheadTM's traded volumes increased by 89%, from 7.48 to 14.18 TWh. Powernext FuturesTM kicks off to a promising debut with 12.86 TWh traded in less than 7 months. - Less volatile prices: During 2004, the base price averaged 28.13 euro/MWh, and the peak prices averaged 33.71 euro/MWh. Compared to 2003, these prices decreased by an average of 3.7% on base-load and 10.9% on peak-load. In comparison to the two previous years, the daily volatility has noticeably settled down with 27% on base-load and 37% on peak-load. - Increasing liquidity: 10 new members joined Powernext Day-AheadTM in 2004. The activity level of the members remains very high as 89% of them trade on an actual daily basis during 2004. The market resiliency stays strong. In December, an additional market 50 MW order on each hour resulted in a balance price variation of only 0.16 euro/MWh, or 0.53% of this balance price. For a 100 MW order, the resiliency is 0.32 euro/MWh, or 1.07% of the balance price. Thus, in 2004, Powernext Day-AheadTM consolidates its role as a short term reference price. Moreover, in 2004, Powernext launched a futures market, Powernext FuturesTM. This new market segment proposes contracts tradable up to 2 years ahead of delivery

  9. Comparative 3-D Modeling of tmRNA

    Directory of Open Access Journals (Sweden)

    Wower Iwona

    2005-06-01

    Full Text Available Abstract Background Trans-translation releases stalled ribosomes from truncated mRNAs and tags defective proteins for proteolytic degradation using transfer-messenger RNA (tmRNA. This small stable RNA represents a hybrid of tRNA- and mRNA-like domains connected by a variable number of pseudoknots. Comparative sequence analysis of tmRNAs found in bacteria, plastids, and mitochondria provides considerable insights into their secondary structures. Progress toward understanding the molecular mechanism of template switching, which constitutes an essential step in trans-translation, is hampered by our limited knowledge about the three-dimensional folding of tmRNA. Results To facilitate experimental testing of the molecular intricacies of trans-translation, which often require appropriately modified tmRNA derivatives, we developed a procedure for building three-dimensional models of tmRNA. Using comparative sequence analysis, phylogenetically-supported 2-D structures were obtained to serve as input for the program ERNA-3D. Motifs containing loops and turns were extracted from the known structures of other RNAs and used to improve the tmRNA models. Biologically feasible 3-D models for the entire tmRNA molecule could be obtained. The models were characterized by a functionally significant close proximity between the tRNA-like domain and the resume codon. Potential conformational changes which might lead to a more open structure of tmRNA upon binding to the ribosome are discussed. The method, described in detail for the tmRNAs of Escherichia coli, Bacillus anthracis, and Caulobacter crescentus, is applicable to every tmRNA. Conclusion Improved molecular models of biological significance were obtained. These models will guide in the design of experiments and provide a better understanding of trans-translation. The comparative procedure described here for tmRNA is easily adopted for the modeling the members of other RNA families.

    The design of the Barrel DIRC detector for the future PANDA experiment at FAIR contains several important improvements compared to the successful BABAR DIRC, such as focusing and fast timing. To test those improvements as well as other design options a prototype was build and successfully tested in 2012 with particle beams at CERN. The prototype comprises a radiator bar, focusing lens, mirror, and a prism shaped expansion volume made of synthetic fused silica. An array of micro-channel plate photomultiplier tubes measures the location and arrival time of the Cherenkov photons with sub-nanosecond resolution. The development of a fast reconstruction algorithm allowed to tune construction details of the detector setup with test beam data and Monte-Carlo simulations.

    Jayasankar, C. K.; Renuka ^Devi, A.

    1996-09-01

    Optical properties of Tm 3+ ions are investigated in the following lithium borate (LBO) glasses: Li 2CO 3 + H 3BO 3 and MCO 3 + Li 2CO 3 + H 3BO 3 (M = Mg, Ca, Sr and Ba). The assigned energy level data of Tm 3+ (4f 12) in these borate glasses as well as the data that are available for some other systems in the literature are analysed in terms of a parametrized Hamiltonian model that includes 14 free-ion parameters. The absorption linestrengths are measured for Tm 3+:LBO glasses. Using these data, intensity parameters (Ω λ, λ = 2, 4, 6), radiative transition probabilities, radiative lifetimes, fluorescence branching ratios and integrated absorption cross-sections for fluorescent levels of Tm 3+:LBO glasses are calculated by applying Judd-Ofelt theory. The effect of glass network formers and glass modifiers on the optical properties of Tm 3+:glasses are discussed.

    NEXT-100 is an electroluminescent high pressure Time Projection Chamber currently under construction. It will search for the neutrino-less double beta decay in 136Xe at the Canfranc Underground Laboratory. NEXT-100 aims to achieve nearly intrinsic energy resolution and to highly suppress background events by taking advantage of the unique properties of xenon in the gaseous phase as the detection medium. In order to prove the principle of operation and to study which are the best operational conditions, two prototypes were constructed: NEXT-DEMO and NEXT-DBDM. In this paper we present the latest results from both prototypes. We report the improvement in terms of light collection (?~3x?) achieved by coating the walls of NEXT-DEMO with tetraphenyl butadiene (TPB), the outstanding energy resolution of 1 % (Full Width Half Maximum) from NEXT-DBDM as well as the tracking capabilities of this prototype (2.1 mm RMS error for point-like depositions) achieved by using a square array of 8x8 SiPMs.

    Full Text Available This study evaluated the sealing ability of apical plugs fabricated with gray MTA AngelusTM sealer, CPM TM sealer and MBPc sealer. The root canals of 98 extracted single-rooted human teeth were instrumented with #5 to #1 Gates Glidden drills according to the crown-down technique until the #1 drill could pass through the apical foramen. The specimens were then prepared with K-files, starting with an ISO 50 until an ISO 90 could be visualized 1 mm beyond the apex. After root canal preparation, the external surface of each root was rendered impermeable and roots were assigned to 3 experimental groups (n = 30, which received a 5-mm thick apical plug of gray MTA AngelusTM, CPM TM and MBPc, and two control groups (n=4. The remaining portion of the canal in the experimental groups was filled by the lateral condensation technique. The teeth of each group, properly identified, were fixed on utility wax by their crowns and were placed in plastic flasks, leaving the apex free and facing upward. The flasks were filled with 0.2% Rhodamine B solution, pH 7.0, so as to completely cover the root apex of all teeth. The sealing ability was analyzed by measuring 0.2% Rhodamine B leakage after all groups had been maintained in this solution for 48 hours. Data were analyzed statistically by Kruskal-Wallis test and Dunn test with a=5%. The results showed that, among the tested materials used for fabrication of apical plugs, MBPc sealer had the least amount of leakage with statistically significant difference (p<0.05.

    International Nuclear Information System (INIS)

    The crystals of Tm doped and Tm-Sc co-doped Lu3Al5O12 (LuAG) grown by the floating zone (FZ) method were examined for their optical and scintillation properties. In transmittance spectra, strong absorption lines due to Tm3+ 4f–4f transitions were observed. X-ray excited radioluminescence spectra were measured and broad and sharp emission peaks were detected. The former one was attributed to Sc3+ and the latter one was due to Tm3+ 4f–4f transitions. Scintillation yield enhancement due to Sc co-doping was observed by means of 137Cs pulse height spectra. Scintillation decay times were several tens of μs under pulse X-ray excitation. - Highlights: • LuAG:Tm and LuAG:Tm, Sc single crystals have been grown by the FZ method. • Tm3+ 4f–4f absorption has been observed in transmittance spectra. • Scintillation yield of Tm-doped LuAG has been enhanced by Sc co-doping

  15. Intracellular distribution of TM4SF1 and internalization of TM4SF1-antibody complex in vascular endothelial cells

    International Nuclear Information System (INIS)

    Transmembrane-4 L-six family member-1 (TM4SF1) is a small plasma membrane-associated glycoprotein that is highly and selectively expressed on the plasma membranes of tumor cells, cultured endothelial cells, and, in vivo, on tumor-associated endothelium. Immunofluorescence microscopy also demonstrated TM4SF1 in cytoplasm and, tentatively, within nuclei. With monoclonal antibody 8G4, and the finer resolution afforded by immuno-nanogold transmission electron microscopy, we now demonstrate TM4SF1 in uncoated cytoplasmic vesicles, nuclear pores and nucleoplasm. Because of its prominent surface location on tumor cells and tumor-associated endothelium, TM4SF1 has potential as a dual therapeutic target using an antibody drug conjugate (ADC) approach. For ADC to be successful, antibodies reacting with cell surface antigens must be internalized for delivery of associated toxins to intracellular targets. We now report that 8G4 is efficiently taken up into cultured endothelial cells by uncoated vesicles in a dynamin-dependent, clathrin-independent manner. It is then transported along microtubules through the cytoplasm and passes through nuclear pores into the nucleus. These findings validate TM4SF1 as an attractive candidate for cancer therapy with antibody-bound toxins that have the capacity to react with either cytoplasmic or nuclear targets in tumor cells or tumor-associated vascular endothelium. - Highlights: • Anti-TM4SF1 antibody 8G4 was efficiently taken up by cultured endothelial cells. • TM4SF1–8G4 internalization is dynamin-dependent but clathrin-independent. • TM4SF1–8G4 complexes internalize along microtubules to reach the perinuclear region. • Internalized TM4SF1–8G4 complexes pass through nuclear pores into the nucleus. • TM4SF1 is an attractive candidate for ADC cancer therapy

    2009-01-01

    Carnitine palmitoyltransferase 1 (CPT1) controls the rate of entry of long-chain fatty acids into the mitochondrial matrix for β-oxidation and has been reported to exist as an oligomer. We have investigated the in vivo oligomerization of full-length rat CPT1A (rCPT1A) along with those of the N-terminal truncation/deletion mutants Δ(1–82), Δ(1–18), and Δ(19–30) expressed in yeast mitochondria. The data indicate that in liver mitochondria in vivo CPT1A exists as a hexamer but that during preparation and storage of mitochondria the order of oligomerization is rapidly reduced to the trimer, such that a mixture of hexamer and trimer is observed in isolated mitochondria in vitro. Mutants bearing deletions of different segments of the N terminus (including the more N-terminal of the two transmembrane domains) have the same pattern of oligomerization when expressed in yeast mitochondria. The self-association of the individual rCPT1A transmembrane (TM) domains (TM1, TM2) was also studied using the TOXCAT assay (which measures TM self-association in the Escherichia coli inner membrane). There was minimal self-association of the sequence corresponding to TM1 but significant self-association of TM2 in TOXCAT. Chemical cross-linking and analytical ultracentrifugation of a TM2-derived synthetic peptide showed oligomerization with a similar trimer/hexamer equilibrium to that observed for native rCPT1A in isolated mitochondria. Therefore, there was a correlation between the oligomerization behavior of TM2 peptide and that of the full-length protein. In silico molecular modeling of rCPT1A TM2 highlighted the favorable orientation of GXXXG and GXXXA motifs in the formation of the TM2 hexamer. PMID:19136561

  18. The preparation and characterization of thulium-170 (170Tm)

    International Nuclear Information System (INIS)

    Thulium-170 (170Tm) is a beta emitter radionuclide with the half life of 128.4 days and Eβ (max) of 0.968 MeV. The 170Tm radionuclide also emits γ rays of 84 keV (3.26%) which is suitable for imaging during therapeutic applications. Based on its radiation properties, 170Tm can be used as an alternative radionuclide for bone pain palliation radiopharmaceutical instead of 89SrCl2. The preparation of 170Tm has been carried out by irradiation of natural thulium oxide (Tm2O3) target at RSG - G.A. Siwabessy - Serpong. The irradiated target was dissolved in 1 N HCl solution by gentle warming and evaporated to near dryness then reconstituted in sterile aquabidest. The radiochemical purity of 170TmCl3 was determined by paper chromatography and paper electrophoresis techniques. The activity of 170TmCl3 as well as its radionuclide purity were determined by multichannel γ ray spectrometer (MCA). The solution of 170TmCl3 obtained was in the pH of 1.5 - 2, clear, with the specific activity and radioactive concentration of 1.7 - 2.4 mCi/mg and 17 - 24 mCi/mL, respectively. The solution has the radiochemical purity of 99.14 ± 0.42% and the radionuclide purity of 100%. The stability test result of 170TmCl3 solution showed that the solution was still stable until 30 days at room temperature with the radiochemical purity of 99.43 ± 0.56%. (author)

  19. Results from the FDIRC prototype

    International Nuclear Information System (INIS)

    We present results from a novel Cherenkov imaging detector called the Focusing DIRC (FDIRC). This detector was designed as a prototype of the particle identification system for the SuperB experiment, and comprises 1/12 of the SuperB barrel azimuthal coverage with partial electronics implementation. The prototype was tested in the SLAC Cosmic Ray Telescope (CRT) which provides 3-D muon tracking with an angular resolution of ∼1.5 mrad, track position resolution of 5–6 mm, start time resolution of 70 ps, and a muon low-energy cutoff of ∼2 GeV provided by an iron range stack. The quartz focusing photon camera couples to a full-size BaBar DIRC bar box and is read out by 12 Hamamatsu H8500 MaPMTs providing 768 pixels. We used IRS2 waveform digitizing electronics to read out the MaPMTs. We present several results from our on-going development activities that demonstrate that the new optics design works very well, including: (a) single photon Cherenkov angle resolutions with and without chromatic corrections, (b) S/N ratio between the Cherenkov peak and background, which consists primarily of ambiguities in possible photon paths to a given pixel, (c) dTOP=TOPmeasured–TOPexpected resolutions, and (d) performance of the detector in the presence of high-rate backgrounds. We also describe data analysis methods and point out limits of the present performance. - Highlights: • We present results from a novel Cherenkov imaging detector called the Focusing DIRC (FDIRC). • The prototype was tested in the SLAC Cosmic Ray Telescope (CRT) which provides 3-D muon tracking. • We present several results from our on-going development activities that demonstrate that new optics design works very well. • We describe data analysis methods and point out limits of the present performance

  2. FY97 ICCS prototype specification

    International Nuclear Information System (INIS)

    The ICCS software team will implement and test two iterations of their software product during FY97. This document specifies the products to be delivered in that first prototype and projects the direction that the second prototype will take. Detailed specification of the later iteration will be written when the results of the first iteration are complete. The selection of frameworks to be implemented early is made on a basis of risk analysis from the point of view of future development in the ICCS project. The prototype will address risks in integration of object- oriented components, in refining our development process, and in emulation testing for FEP devices. This document is a specification that identifies products and processes to undertake for resolving these risks. The goals of this activity are to exercise our development process at a modest scale and to probe our architecture plan for fundamental limits and failure modes. The product of the iterations will be the framework software which will be useful in future ICCS code. Thus the FY97 products are intended for internal usage by the ICCS team and for demonstration to the FEP software developers of the strategy for integrating supervisory software with FEP computers. This will be the first of several expected iterations of the software development process and the performance measurements that ICCS will demonstrate, intended to support confidence in our ability to meet project RAM goals. The design of the application software is being carried out in a separate WBS 1.5.2 activity. The design activity has as its FY97 product a series of Software Design Documents that will specify the functionality of the controls software of ICCS. During the testing of this year''s prototypes, the application functionality needed for test will be provided by sample maintenance controls. These are early precursors of controls that can be used for low level device control. Since the devices under test will be represented by

    International Nuclear Information System (INIS)

    The author studied the panoramic radiographs of patients with TM disorders to find changes associated with them that the panorama may serve more information to the diagnosis and treatment of TM disorders. The depth of antegonial notch, the degree of posterior flexure of condyle and ascending ramus, the length of condyle, coronoid process and sigmoid notch were measured on the panoramic views of the 364 joints with TM disorders and 160 control joints. The result show that the affected mandibles show statistically significant shorter condyle, ramus and relatively longer coronoid process to the condyle, deeper antegonial notch and mote concave posterior border of ascending ramus than those of the controls.

  11. Power system reliability enhancement by using PowerformerTM

    Directory of Open Access Journals (Sweden)

    Rahmat-Allah Hooshmand

    2009-01-01

    Full Text Available A high-voltage generator PowerformerTM is a new generation of the AC generators. The most significant advantages of these PowerformerTM are their direct connection to high-voltage grid, higher availability, and more reactive power margin, short term overloading capacity and removing the power transformer from the structure of the power plant. In this paper, the installation effect of these generators on the power system reliability is investigated. The amount of the effects depends on the type and location of the power plant, location of the PowerformerTM, the size of load and network topology. For this purpose, in the 6-bus IEEE RBTS system, the conventional generators are replaced by these new PowerformerTM and then, the reliability indices are evaluated. The simulation results show that the reliability indices such as the expected duration of load curtailment (EDLC and the expected energy not served (EENS are improved. .

  12. GlossmarkTM Technology:An Innovative Digital Watermark

    Institute of Scientific and Technical Information of China (English)

    Beilei Xu; Shen-ge Wang; Chuheng Liu

    2004-01-01

    GlossmarkTM technology is a digital watermark process that embeds a visually striking gloss image within a high quality color print without the need of special papers or toners. It utilizes the angular dependence of gloss to create a differential-gloss image through the modulation of halftone structures. Both the primary image and the embedded GlossmarkTM image can be distinctively viewed from different perspectives with little interference. The strong directional nature of the gloss and the subtle halftone modulation process make GlossmarkTM images very difficult to detect by a scanner and even more challenging to reproduce through scanning and printing. The GlossmarkTM technology is ideally suitable for document authentication and graphics enhancement. Its digital implementation provides a capability to embed variable data as digital watermarks into individual prints quickly and economically.

    Synthesis and crystal structure, magnetization and heat capacity measurements of phase pure polycrystalline TmVO3 are reported. TmVO3 was stabilized in the orthorhombic structure by thermal treatment of the precursor TmVO4 in a reducing atmosphere. Magnetization and heat capacity measurements reveal the presence of several successive structural and magnetic phase transitions in this compound. At T = 108 K, the sample undergoes a transition from a paramagnetic state to an antiferromagnetic state, followed by a second transition at 78 K which is related to spin and orbital reorientation. The heat capacity measurements reveal the presence of a third transition in the paramagnetic state (at T = 175 K), which corresponds to a structural phase transition and orbital ordering. At low temperatures (~15 K) and weak fields, there is an anomaly in the magnetization, which may be associated with antiferromagnetic short range ordering of the Tm3+ ions.

    2002-01-01

    The microscopic defects have been investigated for crystal Tm3+/Yb3+:YVO4. These defects mainly include the inclusions (solid inclusions, bubbles and inclusions of the liquid phase), dendrites and growth stripes. They are caused by in-pure raw materials, unstable growth conditions, super-cooling component and so on. Tm3+/Yb3+:YVO4 crystals of large size and excellent optical quality are grown by improving the growth conditions to eliminate these defects.

    International Nuclear Information System (INIS)

    In this paper, a new tellurite glass (85TeO2·5.0Nb2O5·5.0ZnO·5.0LiF) doped with 1 mol% Tm2O3 was prepared by melt-quenching technique. Differential scanning calorimetry (DSC) measurements indicate a good thermal stability, X-ray diffraction patterns show no sign of crystallization. Precise refractive index measurements were performed on five different wavelengths by a prism spectrometer. The optical energy gap, the Sellmeier energy gap and the dispersion energy were estimated. Judd–Ofelt intensity parameters were evaluated in order to obtain electric and magnetic-dipole transition probabilities, branching ratios and radiative lifetimes of several excited states of Tm3+. The classical McCumber theory was used to evaluate the emission cross-sections for the 3F4→3H6 transition at a wavelength of around 1.8 µm. The characteristics of down-conversion luminescence in the visible range were studied by exciting Tm3+ ions into the 1G4 level. Furthermore the structure of this glass was analyzed by Raman spectroscopy. - Highlights: • A new thermally stable tellurite glass (TNZL doped 1 mol% Tm3+) was synthesized by a melt-quenching method. • A complete Judd–Ofelt spectroscopic evaluation of the TNZL:Tm glass is presented. • A high gain coefficient and emission cross section are obtained for Tm3+ in TNZL glass in the 1.8 μm region. • The TNZL:Tm glass would be a potential laser operation around 1.8 μm emission. • TNZL:Tm is a good candidate for generate a blue light for color display devices and light emitting diodes

    Well established in the field of scintillator detection, Caesium Iodide remains at the forefront of scintillators for use in modern calorimeters. Recent developments in photosensor technology have lead to the production of Large Area Avalanche Photo Diodes (LAAPDs), a huge advancement on traditional photosensors in terms of high internal gain, dynamic range, magnetic field insensitivity, high quantum efficiency and fast recovery time. The R{sup 3}B physics programme has a number of requirements for its calorimeter, one of the most challenging being the dual functionality as both a calorimeter and a spectrometer. This involves the simultaneous detection of ∼300MeV protons and gamma rays ranging from 0.1 to 20 MeV. This scintillator – photosensor coupling provides an excellent solution in this capacity, in part due to the near perfect match of the LAAPD quantum efficiency peak to the light output wavelength of CsI(Tl). Modern detector development is guided by use of Monte Carlo simulations to predict detector performance, nonetheless it is essential to benchmark these simulations against real data taken with prototype detector arrays. Here follows an account of the performance of two such prototypes representing different polar regions of the Barrel section of the forthcoming CALIFA calorimeter. Measurements were taken for gamma–ray energies up to 15.1 MeV (Maier-Leibnitz Laboratory, Garching, Germany) and for direct irradiation with a 180 MeV proton beam (The Svedberg Laboratoriet, Uppsala, Sweden). Results are discussed in light of complementary GEANT4 simulations. -- Highlights: •Prototypes corresponding to different sections of the forthcoming CALIFA Barrel calorimeter were tested. •The response to both high energy gamma rays and high energy protons was observed. •This response was reproduced by use of R3BROOT simulations, the geometry extrapolated to predict performance of the complete calorimeter. •Effects such as energy straggling of wrapping

  1. Electronic structure of Zr-TM-Al (TM=Ni, Cu) bulk metallic glasses

    International Nuclear Information System (INIS)

    The valence-band electronic structures of Zr-TM-Al (TM=Ni, Cu) bulk metallic glasses have been investigated by means of synchrotron-radiation photoelectron spectroscopy. Their valence-band spectra show Zr 4d-, Ni 3d- and Cu 3d-derived bands at the binding energies of 0.5, 2.0 and 3.6 eV, respectively. The Zr 4d-derived band becomes prominent around the excitation photon energy hv of 40 eV. It is found that the wider the supercooled liquid region ΔTx=Tx-Tg (Tx: the crystallization temperature, Tg: the glass transition temperature), the larger the peak binding energy of the Zr 4d-derived band becomes. For the photoexcitation at hv - 18 eV, where the Zr 4d states less contribute to the spectrum, the spectral intensity reduces towards the Fermi level. This may imply the formation of a pseudogap in the sp bands. It is also found that the width of the pseudogap for the occupied states becomes wider as ΔTx is increased. These spectral findings suggest that both the strength of the chemical bonding around Zr and the reduction in the electronic energy because of the pseudogap formation and the chemical bonding contribute to the large glass formation ability of the Zr-Cu-Al metallic glasses.

  2. Icosahedral Phase Formation In Al-Cu-Fe-Tm (Tm=Si, Mg, B) Alloys

    International Nuclear Information System (INIS)

    Discovery of quasicrystals is considered to be one of the most significant discoveries in material science in last over fifteen years. To date, both stable and metastable quasicrystalline phases investigated in a great number of binary, ternary and multicomponent metallic systems. In the present investigation, the effect of forth element (TM=Si, Mg, B) on the formation of quasicrystal structure in mechanically alloyed Al65Cu20Fe10TM5 alloys was investigated by X-ray diffraction (XRD) and differential thermal analysis (DTA). It was found that icosahedral quasicrystalline phase (i-phase) was formed directly by mechanical alloying of crystalline elemental powders. The present investigation showed that the i-phase was unstable with long time milling and transformed into crystalline β-Al(Cu,Fe) solid solution phase (β-phase). DTA traces obtained from the powders during heating, up to 1200 degree, showed an exothermic peak around 840 degree and an endothermic peak around 1000 degree. The exothermic peak corresponded to the formation of i-phase and the endothermic effect corresponded to melting of the alloys. The results of the present investigation are discussed in light of the current understanding of the phase stability in complex systems.

  3. LEP vacuum chamber, early prototype

    CERN Multimedia

    1978-01-01

    The structure of LEP, with long bending magnets and little access to the vacuum chamber between them, required distributed pumping. This is an early prototype for the LEP vacuum chamber, made from extruded aluminium. The main opening is for the beam. The small channel to the right is for cooling water, to carry away the heat deposited by the synchroton radiation from the beam. The 4 slots in the channel to the left house the strip-shaped ion-getter pumps (see 7810255). The ion-getter pumps depended on the magnetic field of the bending magnets, too low at injection energy for the pumps to function well. Also, a different design was required outside the bending magnets. This design was therefore abandoned, in favour of a thermal getter pump (see 8301153 and 8305170).

    The European PARTNER project developed a prototypical system for sharing hadron therapy data. This system allows doctors and patients to record and report treatment-related events during and after hadron therapy. It presents doctors and statisticians with an integrated view of adverse events across institutions, using open-source components for data federation, semantics, and analysis. There is a particular emphasis upon semantic consistency, achieved through intelligent, annotated form designs. The system as presented is ready for use in a clinical setting, and amenable to further customization. The essential contribution of the work reported here lies in the novel data integration and reporting methods, as well as the approach to software sustainability achieved through the use of community-supported open-source components.

  5. The LHCb hadron calorimeter prototype

    International Nuclear Information System (INIS)

    LHCb is a Large Hadron Collider Beauty experiment dedicated for precision measurements of CP violation and rare phenomena. The experiment is built as a single arm detector covering a forward angle between ∼ 15 mrad and ∼ 300 mrad. It consists in a vertex detector, a tracking system, two RICH detectors, a calorimeter system comprising a preshower, electromagnetic and hadron sections, and a muon system. The role of the calorimeters is to provide identification of the electrons and hadrons for trigger and offline analysis with measurements of position and energy. The hadron calorimeter (HCAL) has to provide data for the trigger and to assist in background suppression when B decays are reconstructed. In 1997 an HCAL prototype stack of 3 modules, each having the dimensions 96 x 16 x 153 cm3, has been constructed and exposed to the X7 test beams of the SPS at CERN. Each module is constructed from scintillator tiles embedded in an iron structure, which are parallel to the beam direction in a staggered arrangement. The cell segmentation of the 1997 prototype was 16 x 16 cm2 and had a 2-fold in depth readout. Around 3760 spacer plates and weld straps necessary for all 6 modules were supplied by Romanian group of IFIN-HH in 1997, as well as about 200 master plates for two modules in 1998. The assembling of the modules was performed at CERN by people of our group, IHEP Serpukhov and CERN. During November 1997 test beam data were taken with pion and electron beams of 5 up to 50 GeV/c momenta. The energy spectra for pions were obtained. A shift of about 1.3 GeV of the energy mean value with respect to the beam energy was observed for all studied energies. This could be due to different effects. The energy resolution as a function of the beam energy fitted by the dependence σ/E = a/√E + b gives parameters in agreement with the values expected from Monte Carlo. Uniformity response for pions at 20 GeV oscillates within 2.5 % around the mean value. Data taken with ECAL

    One of the most successful techniques for the detection of air showers produced by ultra-high-energy cosmic rays are fluorescence telescopes. The light produced by de-exciting nitrogen in the atmosphere is typically detected by photomultiplier tubes (PMTs). This technique has been successfully used by the Pierre Auger Observatory in Argentina for many years. Silicon photomultipliers (SiPMs) promise higher photon detection efficiencies than PMTs. This and other advantages motivate the construction of the fluorescence telescope prototype FAMOUS (First Auger Multi-pixel photon counter camera for the Observation of Ultra-high-energy air Showers) which makes use of SiPMs. In this talk we discuss the FAMOUS telescope with a new 64-pixel camera including power supply and DAQ.

    A new prototype device for beta-ray measurement, a plastic scintillation counter, was assembled as an alternative device to liquid scintillation counters. This device uses plastic scintillation sheets (PS sheets) as a sample applicator without the use of a liquid scintillator. The performance was evaluated using tritium labeled compounds, and good linearity was observed between the activity and net count rate. The calculated detection limit of the device was 0.01 Bq mL−1 after 10 h measurement for 2 mL sample. - Highlights: • A new device of plastic scintillation counter was developed to measure beta emitters. • High sensitivity with low detection limit was performed for a tritium compound. • A detection limit of tritium was 0.01 Bq mL−1 for a 10 h measurement. • A plastic scintillation counter generated no radioactive organic waste fluid. • A plastic scintillation counter could analyze qualitatively and quantitatively

    We have completed a design of the Prototype Moving-Ring Reactor. The fusion fuel is confined in current-carrying rings of magnetically-field-reversed plasma (Compact Toroids). The plasma rings, formed by a coaxial plasma gun, undergo adiabatic magnetic compression to ignition temperature while they are being injected into the reactor's burner section. The cylindrical burner chamber is divided into three burn stations. Separator coils and a slight axial guide field gradient are used to shuttle the ignited toroids rapidly from one burn station to the next, pausing for 1/3 of the total burn time at each station. D-T-3He ice pellets refuel the rings at a rate which maintains constant radiated power

  10. Prototype international quality assurance program

    International Nuclear Information System (INIS)

    The international community presently lacks the ability to determine the quality and credibility of environmental measurements that is required to make sound decisions in matters related to international security, public health, and investment-related considerations. The ultimate goal of the work described in this article is to develop a credible information base including measurement capability for determination of environmental contamination and the potential for proliferation of material components of chemical or nuclear weapons. This study compared the accuracy obtained by six Russian and six U.S. laboratories for samples representative of classes of trace metals, dioxing-furans, and radioactive substances. The results obtained in this work indicate that current estimates for laboratory accuracy are likely overly optimistic. The weaknesses discovered by this prototype U.S. - Russia study also exist within the broader international community of laboratories. Further work is proposed to address the urgent need for the international community to improve performance evaluations for analytical measurements. (author)

    As an alternative and adjunct to visual displays, auditory exploration of data via sonification (data controlled sound) and audification (audible playback of data samples) is promising for complex or rapidly/temporally changing visualizations, for data exploration of large datasets (particularly multi-dimensional datasets), and for exploring datasets in frequency rather than spatial dimensions (see also International Conferences on Auditory Display ). Besides improving data exploration and analysis for most researchers, the use of sound is especially valuable as an assistive technology for visually-impaired people and can make science and math more exciting for high school and college students. Only recently have the hardware and software come together to make a cross-platform open-source sonification tool feasible. We have developed a prototype sonification data analysis tool using the JavaSound API and NASA GSFC's ViSBARD software . Wanda Diaz Merced, a blind astrophysicist from Puerto Rico, is instrumental in advising on and testing the tool.

  13. Laser desorption/ionization mass spectrometry on nanostructured semiconductor substrates: DIOS(TM) and QuickMass(TM)

    Law, K. P.

    2010-02-01

    In the era of systems biology, new analytical platforms are under demand. Desorption/ionization on silicon mass spectrometry (DIOS-MS) is a promising high throughput laser mass spectrometry approach that has attracted a lot of attention, and has been commercialized. Another substrate material manufactured by physical method has also been made commercially available under the trade name of QuickMass(TM). These two commercial substrates, DIOS(TM) and QuickMass(TM), were investigated independently from the manufacturers and were characterized by a number of advanced surface techniques. This work determined (1) the correlation between the substrate physicochemical properties and their LDI activity, (2) the feasibility of metabolic profiling from complex biological matrices and (3) the laser desorption/ionization mechanism. The DIOS(TM) substrate was characterized with a thick nano-sized porous layer, a high surface concentration of fluorocarbon and silicon oxides and super-hydrophobicity. In contrast, the QuickMass(TM) substrate consisted of a non-porous germanium thin-film. The relatively high ionization efficiency obtained from the DIOS(TM) substrate was contributed to the fluorosilane manufacturing processes and its porous morphology. Despite the QuickMass(TM) substrate being less effective, it was noted that the use of germanium affords a self-cleaning mechanism and suppresses background interference of mass spectra. The suitability of DIOS(TM) substrates for metabolic profiling of complex biological matrices was demonstrated. DIOS mass spectra of human blood plasma, human urine and animal liver tissue extracts were produced. Suitable extraction methods were found to be important, but relatively simplified approaches were sufficient. Further investigations of the DIOS desorption/ionization mechanism were carried out. The previously proposed sub-surface state reaction could be a molten-solid interfacial state reaction of the substrate and this had a significant

    1999-01-01

    Initiated in January, 1997, under NASA's Office of Life and Microgravity Sciences and Applications, the Wireless Augmented Reality Prototype (WARP) is a means to leverage recent advances in communications, displays, imaging sensors, biosensors, voice recognition and microelectronics to develop a hands-free, tetherless system capable of real-time personal display and control of computer system resources. Using WARP, an astronaut may efficiently operate and monitor any computer-controllable activity inside or outside the vehicle or station. The WARP concept is a lightweight, unobtrusive heads-up display with a wireless wearable control unit. Connectivity to the external system is achieved through a high-rate radio link from the WARP personal unit to a base station unit installed into any system PC. The radio link has been specially engineered to operate within the high- interference, high-multipath environment of a space shuttle or space station module. Through this virtual terminal, the astronaut will be able to view and manipulate imagery, text or video, using voice commands to control the terminal operations. WARP's hands-free access to computer-based instruction texts, diagrams and checklists replaces juggling manuals and clipboards, and tetherless computer system access allows free motion throughout a cabin while monitoring and operating equipment.

  20. A French fuel cell prototype

    International Nuclear Information System (INIS)

    A French prototype of a fuel cell based on the PEM (proton exchange membrane) technology has been designed by Helion, a branch of Technicatome, this fuel cell delivers 300 kW and will be used in naval applications and terrestrial transport. The main advantages of fuel cell are: 1) no contamination, even if the fuel used is natural gas the quantities of CO2 and CO emitted are respectively 17 and 75 times as little as the maximal quantities allowed by European regulations, 2) efficiency, the electric yield is up to 60 % and can reach 80 % if we include the recovery of heat, 3) silent, the fuel cell itself does not make noise. The present price of fuel cell is the main reason that hampers its industrial development, this price is in fact strongly dependant on the cost of its different components: catalyzers, membranes, bipolar plates and the hydrogen supply. This article gives the technical characteristics of the Helion's fuel cell. (A.C.)

  1. Magnetic ordering in Tm5Ni2In4

    International Nuclear Information System (INIS)

    Highlights: • Magnetic structure of Tm5Ni2In4 is reported for the first time. • Tm5Ni2In4 magnetic structure is verified by group theory symmetry analysis. • Diffraction data are supported by magnetometric and calorimetric measurements. - Abstract: Physical properties of the Tm5Ni2In4 compound have been investigated by means of magnetometric, calorimetric as well as neutron diffraction measurements. The compound crystallizes in the orthorhombic Lu5Ni2In4-type crystal structure (space group Pbam, No. 55). The reported results indicate that the sample exhibits an antiferromagnetic ordering below TN = 4.1 K. The Tm3+ ions occupy three crystal positions within unit cell: one 2a site and two 4g sites. Analysis of neutron diffraction data collected at T = 1.5 K, together with group theory symmetry analysis predictions show that Tm magnetic moments form a non-collinear magnetic structure described by the propagation vector k = [0, ½, ½]. The magnetic moments lie in the (0 0 1) plane

  9. Effect of Tm2O3 concentration and hydroxyl content on the emission properties of Tm doped silicate glasses

    International Nuclear Information System (INIS)

    Tm2O3-doped multi-component silicate glasses without alkali ions are prepared using a conventional melt quenching method. The Judd–Ofelt theory is applied to calculate the intensity parameters of the resultant glass. The intensity parameters of silicate glasses without alkali ions are larger than those of silicate glasses with alkali ions. The spontaneous radiation probability of the transition from 3F4 to 3H6 of glasses without alkali ions is 191.89 s−1, which is larger than that of glasses with alkali ions. Moreover, the measured lifetime of the 3F4 energy level of glasses is larger too. Emission cross section results show a maximum value 3.89×10−21 cm2 at 1882 nm. These findings indicate that the glass in this study can be used to realize ∼2 μm lasers. The effect of variations in Tm2O2 concentration on the emission properties is also studied. Cross-relaxation and emission intensity enhance with increasing Tm2O3 content. However, the lifetime of the 3F4 level decreases because of concentration quenching. The influence of OH groups on the emission properties is also investigated. -- Highlights: • Tm2O3 doped silicate glass with no alkali ions is reported. • Radiative properties has been determined using the Judd–Ofelt theory. • Effect of Tm2O3 concentration on emission properties is studied. • Influence of hydroxyl groups on emission properties is investigated

    2012-09-01

    This article reviewed developments of Computerized Numerical Control (CNC) technology in rapid prototyping process. Rapid prototyping (RP) can be classified into three major groups; subtractive, additive and virtual. CNC rapid prototyping is grouped under the subtractive category which involves material removal from the workpiece that is larger than the final part. Richard Wysk established the use of CNC machines for rapid prototyping using sets of 2½-D tool paths from various orientations about a rotary axis to machine parts without refixturing. Since then, there are few developments on this process mainly aimed to optimized the operation and increase the process capabilities to stand equal with common additive type of RP. These developments include the integration between machining and deposition process (hybrid RP), adoption of RP to the conventional machine and optimization of the CNC rapid prototyping process based on controlled parameters. The article ended by concluding that the CNC rapid prototyping research area has a vast space for improvement as in the conventional machining processes. Further developments and findings will enhance the usage of this method and minimize the limitation of current approach in building a prototype.

    2015-04-01

    The word rapid prototyping (RP) was first used in mechanical engineering field in the early 1980s to describe the act of producing a prototype, a unique product, the first product, or a reference model. In the past, prototypes were handmade by sculpting or casting, and their fabrication demanded a long time. Any and every prototype should undergo evaluation, correction of defects, and approval before the beginning of its mass or large scale production. Prototypes may also be used for specific or restricted purposes, in which case they are usually called a preseries model. With the development of information technology, three-dimensional models can be devised and built based on virtual prototypes. Computers can now be used to create accurately detailed projects that can be assessed from different perspectives in a process known as computer aided design (CAD). To materialize virtual objects using CAD, a computer aided manufacture (CAM) process has been developed. To transform a virtual file into a real object, CAM operates using a machine connected to a computer, similar to a printer or peripheral device. In 1987, Brix and Lambrecht used, for the first time, a prototype in health care. It was a three-dimensional model manufactured using a computer numerical control device, a type of machine that was the predecessor of RP. In 1991, human anatomy models produced with a technology called stereolithography were first used in a maxillofacial surgery clinic in Viena. PMID:26015715

  14. Evaluation of a prototype infrasound system

    International Nuclear Information System (INIS)

    Under Department of Energy sponsorship, Sandia National Laboratories and Los Alamos National Laboratory cooperated to develop a prototype infrasonic array, with associated documentation, that could be used as part of the International Monitoring System. The United States Government or foreign countries could procure commercially available systems based on this prototype to fulfill their Comprehensive Test Ban Treaty (CTBT) obligations. The prototype is a four-element array in a triangular layout as recommended in CD/NTB/WP.224 with an element at each corner and one in the center. The prototype test configuration utilize an array spacing of 1 km. The prototype infrasound system has the following objectives: (1) Provide a prototype that reliably acquires and transmits near real-time infrasonic data to facilitate the rapid location and identification of atmospheric events. (2) Provide documentation that could be used by the United States and foreign countries to procure infrasound systems commercially to fulfill their CTBT responsibilities. Infrasonic monitoring is an effective, low cost technology for detecting atmospheric explosions. The low frequency components of explosion signals propagate to long ranges (few thousand kilometers) where they can be detected with an array of sensors. Los Alamos National Laboratory's expertise in infrasound systems and phenomenology when combined with Sandia's expertise in providing verification quality system for treaty monitoring make an excellent team to provide the prototype infrasound sensor system. By September 1997, the prototype infrasound system will have been procured, integrated, evaluated and documented. Final documentation will include a system requirements document, an evaluation report and a hardware design document. The hardware design document will describe the various hardware components used in the infrasound prototype and their interrelationships

    International Nuclear Information System (INIS)

    Novel oxyfluoride glasses SiO2-Al2O3-Na2O-ZnF2 doped with Tm3+ and Tm3+/Yb3+ were fabricated. The optical properties of the synthesized glasses were experimentally and theoretically investigated in detail. According to the Judd-Ofelt theory, the Judd-Ofelt intensity parameters were calculated. With these intensity parameters, the radiative transition probabilities, fluorescence branching ratios and radiative lifetimes were obtained. The fluorescence lifetime and quantum efficiency for 1D2→3F4 emission of Tm3+-singly doped glass were determined to be 12 μs, and 35.3%, respectively. The up-conversion luminescence was observed upon excitation with 980 nm diode laser. The dependence of the up-conversion emission intensity upon the excitation power was examined, and the up-conversion mechanisms were discussed

    A development history and performance capability assessment is presented for the INTA-300 'Flamenco' sounding rocket prototype specimens. The Flamenco is a two-stage solid fuel rocket, based on British sounding rocket technology, that can lift 50 km payloads to altitudes of about 300 km. The flight of the first two prototypes, in 1974 and 1975, pointed to vibration problems which reduced the achievable apogee, and the third prototype's flight was marred by a premature detonation that destroyed the rocket. The fourth Flamenco flight, however, yielded much reliable data.

    The ambitious science goals of the Large Synoptic Survey Telescope (LSST) will be achieved in part by a wide-field imager that will achieve a new level of performance in terms of area, speed, and sensitivity. The instrument performance is dominated by the focal plane sensors, which are now in development. These new-generation sensors will make use of advanced semiconductor technology and will be complemented by a highly integrated electronics package located inside the cryostat. A test laboratory has been set up at Brookhaven National Laboratory (BNL) to characterize prototype sensors and to develop test and assembly techniques for eventual integration of production sensors and electronics into modules that will form the final focal plane. As described in [1], the key requirements for LSST sensors are wideband quantum efficiency (QE) extending beyond lpm in the red, control of point spread function (PSF), and fast readout using multiple amplifiers per chip operated in parallel. In addition, LSST's fast optical system (f71.25) places severe constraints on focal plane flatness. At the chip level this involves packaging techniques to minimize warpage of the silicon die, and at the mosaic level careful assembly and metrology to achieve a high coplanarity of the sensor tiles. In view of the long lead time to develop the needed sensor technology, LSST undertook a study program with several vendors to fabricate and test devices which address the most critical performance features [2]. The remainder of this paper presents key results of this study program. Section 2 summarizes the sensor requirements and the results of design optimization studies, and Section 3 presents the sensor development plan. In Section 4 we describe the test bench at BNL. Section 5 reports measurement results obtained to date oh devices fabricated by several vendors. Section 6 presents a summary of the paper and an outlook for the future work.

  20. On the neutron jet prototype

    International Nuclear Information System (INIS)

    Full text: Fast neutrons are proposed to use, in a deep space, as a recoil mass for low-thrust nuclear fission (or fusion) rocket engine instead of hydrogen heated in nuclear reactor up to 2300 - 2700oC [1, 2]. In particularly, such neutron engines with a long-term operation as well as nuclear powerful or micro-explosions can be used for ensuring of the astronomical safety for the Earth from asteroids in diameter more 50 m. For production of attractive force of 9.81N the propellant expenditure of hydrogen jet with the system specific impulse of ∼ 9000 m s-1 is ∼ 94 kg a day. For fast 1.8 MeV-neutron jet - 45.8 g per day (directed or collimated neutron fluxes). J=1016cm-2 s-1 if a cross-section of rocket nozzle is 1m2 [2]. So, to produce powerful directed or collimated fast neutron fluxes high intensity controlled neutron sources are required (they are, basically, the novel high-flux research reactors, for example, HFRR (Osaka University, Japan), 400 MW (th) and ψ=1016 cm-2 s-1). The most suitable neutron jet prototype is the B-2 facility of the fast reactor BR-5 (SSC RF Obninsk, Russia). This is a 'mono directional disk' with a diameter of 0.25 m; for neutrons with energies > (2, 3) MeV the collimated neutron flux is 1010cm-2 s-1 at the reactor power of 5 MW [3]. The intensification of fast neutron fluences may be up to ∼ 21 for the volume fast neutron source (the fast reactor with a diameter of ∼ 0.8 m) and ∼ 39 for point one by using an iron reflecting tube one side of which is closed (end wall - the effects of a neutron searchlight) [4]. The thickness of walls is 40 cm [5]. The additional intensification is possible by using 6LiD-thermal neutron-flux converter into ∼ 14 MeV-neutrons from (dT), (6LiT)-fusion reactions [6

    High-quality Tm doped β-PbF2 crystal is grown by the Bridgman method in a nonvacuum atmosphere. Optical absorption spectra were acquired and analysed in the framework of the Judd-Ofelt theory. Values of radiative transition rates and luminescence branching ratios calculated using phenomenological intensity parameters Ωλ were compared to corresponding experimental values derived from measurement of luminescence spectra and decay curves. The emission cross-sections of the 3 F 4 → 3 H 6 transitions of the Tm3+ ions at 1.86 μm wavelengths were estimated by the use of the Fuchtbauer-Ladengurg method.

    International Nuclear Information System (INIS)

    A 2.5-MeV prototype of a 'Compact 12-MeV Proton Linac for PET Isotope Production' is under construction at Linac Systems. This unit will serve as the 'proof of principle' for the revolutionary new Rf Focused Drift tube (RFD) linac structure. Both the prototype and the production unit will operate at 600 MHz. The prototype comprises a 25- keV proton ion source, a short LEBT, a 0.65-m-long RFQ linac to 0.8 MeV, and a 0.35-m-long RFD linac to 2.5 MeV. Because of the similarity of the accelerating and focusing properties of the RFQ and RFD linac structures, no matching section is required between them. The two linac structures will be resonantly coupled together and powered by a collection of planar triodes. The prototype is scheduled for completion in the fall of 1997. (author)

  15. Magnetic resonance imaging of trilucent TM breast implants

    International Nuclear Information System (INIS)

    AIM: To demonstrate the magnetic resonance imaging (MRI) appearances of intact and ruptured Trilucent TM implants with imaging and surgical correlation. The appearances of the implant transponder artefact are also described MATERIALS AND METHODS: A retrospective review of the MRI findings in 34 patients with bilateral subpectoral Trilucent TM breast implants (Lipomatrix, Inc./Collagen Aesthetics International Inc., Neuchatel, Switzerland) was performed. Patients under implant surveillance and those with suspected implant rupture formed the study group. Imaging findings were correlated with surgical appearances. RESULTS: Surgical correlation was available in 53% of patients. Fifty per cent (18/36) of implants were intact at surgery, 50% (18/36) of implants were ruptured. Of the 18 ruptured implants, 17 were intracapsular ruptures and one an extracapsular rupture. The sensitivity of MRI for detection of intracapsular rupture in Trilucent TM breast implants was 82% specificity 76%, positive predictive value 78%, negative predictive value 81% and accuracy 79% in this study group. No case of implant rupture was obscured by the transponder artefact. Four implants were found to have 'pseudocapsules' at surgery (5·9%), the implants were intact with fluid present between the implant and capsule. Only one pseudocapsule was demonstrated on MRI. CONCLUSION: Magnetic resonance imaging is currently the most accurate technique for diagnosis of implant rupture in Trilucent TM breast implants. Transponder artefact does not appear to interfere with the assessment of implant rupture. Elson, E. M. et al. (2002)

  20. Field evaluation of prototype electrofibrous filters

    International Nuclear Information System (INIS)

    New prototype electrofibrous filters were designed, built and evaluated in laboratory tests and in field installations. Two prototypes were designed for use in nuclear ventilation ducts as prefilters to HEPA filters. One prototype is designed to be a permanent component of the ventilation system while the other is a disposable unit. The disposable electrofibrous prefilter was installed in the exhaust stream of a glove box in which barrels of uranium turnings are burned. Preliminary tests show the disposal prefilter is effectively prolonging the HEPA filter life. An earlier prototype of the rolling prefilter was upgraded to meet the increased requirements for installation in a nuclear facility. This upgraded prototype was evaluated in the fire test facility at LLNL and shown to be effective in protecting HEPA filters from plugging under the most severe smoke conditions. The last prototype described in this report is a recirculating air filter. After demonstrating a high performance in laboratory tests the unit was shipped to Savannah River where it is awaiting installation in a Pu fuel fabrication facility. An analysis of the particulate problem in Savannah River indicates that four recirculating air filter will save $172,000 per year in maintenance costs

    2013-09-01

    This document serves as both an FY2103 End-of-Year and End-of-Project report on efforts that resulted in the design of a prototype fast neutron multiplicity counter leveraged upon the findings of previous project efforts. The prototype design includes 32 liquid scintillator detectors with cubic volumes 7.62 cm in dimension configured into 4 stacked rings of 8 detectors. Detector signal collection for the system is handled with a pair of Struck Innovative Systeme 16-channel digitizers controlled by in-house developed software with built-in multiplicity analysis algorithms. Initial testing and familiarization of the currently obtained prototype components is underway, however full prototype construction is required for further optimization. Monte Carlo models of the prototype system were performed to estimate die-away and efficiency values. Analysis of these models resulted in the development of a software package capable of determining the effects of nearest-neighbor rejection methods for elimination of detector cross talk. A parameter study was performed using previously developed analytical methods for the estimation of assay mass variance for use as a figure-of-merit for system performance. A software package was developed to automate these calculations and ensure accuracy. The results of the parameter study show that the prototype fast neutron multiplicity counter design is very nearly optimized under the restraints of the parameter space.

    2013-12-01

    Full Text Available Aim of study: The aim of this study was performance of four non-parametric algorithms including the k-NN, SVR, RF and ANN to estimate forest volume and basal area attributes using combination of Aerial Laser Scanner and Landsat-TM data.Area of study: Data in small part of a mixed managed forest in the Waldkirch region, Germany.Material and methods: The volume/ha and basal area/ha in the 411 circular plots were estimated based on DBH and height of trees using volume functions of study area. The low density ALS raw data as first and last pulses were prepared and automatically classified into vegetation and ground returns to generate two fine resolution digital terrain and surface models after noise removing. Plot-based height and density metrics were extracted from ALS data and used both separated and combined with orthorectified and processed TM bands. The algorithms implemented with different options including k-NN with different distance measures, SVR with the best regularized parameters for four kernel types, RF with regularized decision tree parameters and ANN with different types of networks. The algorithm performances were validated using computing absolute and percentage RMSe and bias on unused test samples.Main results: Results showed that among four methods, SVR using the RBF kernel could better estimate volume/ha with lower RMSe and bias (156.02 m3 ha–1 and 0.48, respectively compared to others. In basal area/ha, k-NN could generate results with similar RMSe (11.79 m3 ha–1 but unbiased (0.03 compared to SVR with RMSe of 11.55 m3 ha–1 but slightly biased (–1.04.Research highlights: Results exposed that combining Lidar with TM data could improve estimations compared to using only Lidar or TM data.Key words: forest attributes estimation; ALS; TM; non-parametric algorithms.

    2016-05-01

    Full Text Available Context and purpose: Too much sitting is now recognised as a common risk factor for several health outcomes, with the workplace identified as a key setting in which to address prolonged sitting time. The Stand Up Australia intervention was designed to reduce prolonged sitting in the workplace by addressing influences at multiple-levels, including the organisation, the environment, and the individual. Intervention success has been achieved within the context of randomised controlled trials, where research staff deliver several of the key intervention components. This study describes the initial step in the multi-phase process of scaling up the Stand Up Australia intervention for workplace translation. Methods: A research-government partnership was critical in funding and informing the prototype for the scaled up BeUpstanding programTM. Evidence, protocols and materials from Stand Up Australia were adapted in collaboration with funding partner Workplace Health and Safety Queensland to ensure consistency and compatibility with existing government frameworks and resources. In recognition of the key role of workplace champions in facilitating workplace health promotion programs, the BeUpstanding programTM is designed to be delivered through a stand-alone, free, website-based toolkit using a 'train the champion' approach. Key findings and significance: The BeUpstanding programTM was influenced by the increasing recognition of prolonged sitting as an emerging health issue as well as industry demand. The research-government partnership was critical in informing and resourcing the development of the scaled-up program.

    2008-01-01

    This study evaluated the sealing ability of apical plugs fabricated with gray MTA Angelus sealer, CPM TM sealer and MBPc sealer. The root canals of 98 extracted single-rooted human teeth were instrumented with #5 to #1 Gates Glidden drills according to the crown-down technique until the #1 drill could pass through the apical foramen. The specimens were then prepared with K-files, starting with an ISO 50 until an ISO 90 could be visualized 1 mm beyond the apex. After root canal preparation, the external surface of each root was rendered impermeable and roots were assigned to 3 experimental groups (n = 30), which received a 5-mm thick apical plug of gray MTA Angelus, CPM and MBPc, and two control groups (n=4). The remaining portion of the canal in the experimental groups was filled by the lateral condensation technique. The teeth of each group, properly identified, were fixed on utility wax by their crowns and were placed in plastic flasks, leaving the apex free and facing upward. The flasks were filled with 0.2% Rhodamine B solution, pH 7.0, so as to completely cover the root apex of all teeth. The sealing ability was analyzed by measuring 0.2% Rhodamine B leakage after all groups had been maintained in this solution for 48 hours. Data were analyzed statistically by Kruskal-Wallis test and Dunn test with a=5%. The results showed that, among the tested materials used for fabrication of apical plugs, MBPc sealer had the least amount of leakage with statistically significant difference (p<0.05).

  8. Thermal stability and glass-forming ability of amorphous Nd-Al-TM (TM=Fe, Co, Ni or Cu) alloys

    International Nuclear Information System (INIS)

    Bulk amorphous alloys were prepared for Nd70Al10TM20 and Nd60Al10TM30 (TM=Fe or Co) alloys by copper mold casting. The maximum sample thickness for glass formation reaches 15 mm for the Nd-Al-Fe alloys and 5 mm for the Nd-Al-Co alloys. A significant difference in the phase transition upon heating is recognized between the Fe- and Co-containing alloys. No glass transition before crystallization is observed for the Nd-Al-Fe alloys, but the Nd-Al-Co alloys exhibit the glass transition. The ΔTx(=Tx-Tg) and Tg/Tm are 40-55 K and 0.65-0.67, respectively, for the latter alloys. The absence of supercooled liquid for the former alloys is different from those for all bulk amorphous alloys reported up to date. The Tx/Tm and ΔTm(=Tm-Tx) are 0.85-0.89 and 88-137 K, respectively, for the Nd-Al-Fe alloys and, hence, the large glass-forming ability is presumably due to the high Tx/Tm and small ΔTm values.

  11. The energy performance of prototype holographic glazings

    Papamichael, K.; Beltran, L.; Furler, R.; Lee, E. S.; Selkowitz, S.; Rubin, M.

    1993-02-01

    We report on the simulation of the energy performance of prototype holographic glazings in commercial office buildings in a California climate. These prototype glazings, installed above conventional side windows, are designed to diffract the transmitted solar radiation and reflect it off the ceiling, providing adequate daylight illumination for typical office tasks up to 10m from the window. In this study, we experimentally determined a comprehensive set of solar-optical properties and characterized the contribution of the prototype holographic glazings to workplane illuminance in a scale model of a typical office space. We then used the scale model measurements to simulate the energy performance of the holographic glazings over the course of an entire year for four window orientations (North, East, South and West) for the inland Los Angeles climate, using the DOE-2.lD building energy analysis computer program. The results of our experimental analyses indicate that these prototype holographic glazings diffract only a small fraction of the incident light. The results of this study indicate that these prototype holographic glazings will not save energy in commercial office buildings. Their performance is very similar to that of clear glass, which, through side windows, cannot efficiently illuminate more than a 4-6 m depth of a building's perimeter, because the cooling penalties due to solar heat gain are greater than the electric lighting savings due to daylighting.

  12. Design and development of cold prototypes of post coupled Alvarez type Drift Tube Linac for LEHIPA

    International Nuclear Information System (INIS)

    Alvarez type Drift Tube Linac (DTL) is used for acceleration of proton beaming low energy section of beta ranging from 0.04 to 0.40. DTL form part of LEHIPA (Low Energy High Intensity Proton Accelerator) for acceleration of protons from 3 MeV to 20 MeV energy. DTL is cylindrical RF cavity resonating in TM010 mode at 352.21 MHz frequency. It consists of array of drift tubes arranged ensuring that DTL centre and Drift Tube centre are concentric. The Drift Tubes also houses Permanent Magnet Quadrupole for transverse focusing of proton beam. A twelve cell cold prototype of DTL section is designed, developed and fabricated at Bhabha Atomic Research Centre, Trombay. Complete DTL accelerator consists of eight such DTL sections. High frequency microwave simulations are carried out in SOPRANO, vector fields and COMSOL simulation software. This prototype DTL is 1640.56 mm long cavity with 520 mm ID, 600 mm OD and consists of eleven Drift Tubes, two RF end flanges, three slug tuners, six post couplers, three RF field monitors, one RF waveguide coupler, two DN100 vacuum flanges and DTL tank platform with alignment features. Girder based Drift tube mounting arrangement utilizing uncompressing energy of disc springs for optimum combo RF-vacuum seal compression is worked out and implemented. This paper discusses design of this vacuum cavity and discusses results on mechanical accuracy achieved on scaled pre-prototype, and comments on low level RF measurements and vacuum integrity on the cold DTL prototype.

    Full Text Available Hypercholesterolemia is the major cause of cardiovascular diseases leading to myocardial infarctions leading to considerable morbidity and mortality. During the past decade a group of molecules referred to as statins such as simvastatin, atrovastatin have been tried with great success in reducing total cholesterol. These molecules act by inhibiting the HMG CoA reductase enzyme thereby interfering with the synthesis of cholesterol. But statins reduce all the cholesterol including HDL cholesterol. Long term drug vigilance activity has revealed serious side effects of tendinopathy and related musculoskeletal disorders in some of the subjects. In an effort to manage hypercholesterolemia without serious side effects in a natural way we had tried the use of Amlamax TM a reconstituted, purified, standardized dried extract of amla ( Emblica officinalis containing 30% ellagitannins with other hydrolysable tannins on humans. We report the hitherto unobserved significant elevation of HDL cholesterol by the administration of Amlamax TM

    2013-12-30

    We demonstrate a high power all-fiber single frequency Tm-doped fiber amplifier. The maximum output power reached 102 W and the central wavelength was 1.97 μm. The single frequency laser signal from a seed laser was amplified based on a monolithic master oscillator power amplifier (MOPA) configuration. The slope efficiency was about 50% against the absorbed pump power. Neither parasitic lasing nor nonlinear effect was observed in the monolithic fiber amplifier. The SBS threshold of the single frequency Tm-doped fiber amplifier was analyzed and estimated. The output power is not limited by the SBS threshold and could be further improved by increasing the pump power. To the best of our knowledge, this is the first demonstration of average power exceeding 100 W from monolithic all-fiber laser near 2 μm wavelength. PMID:24514831

    A computerized operator support system (COSS) is proposed for use in nuclear power plants to assist control room operators in addressing time-critical plant upsets. A COSS is a collection of technologies to assist operators in monitoring overall plant performance and making timely, informed decisions on appropriate control actions for the projected plant condition. A prototype COSS was developed in order to demonstrate the concept and provide a test bed for further research. The prototype is based on four underlying elements consisting of a digital alarm system, computer-based procedures, piping and instrumentation diagram system representations, and a recommender module for mitigation actions. The initial version of the prototype is now operational at the Idaho National Laboratory using the Human System Simulation Laboratory.

  20. Prototype Hanford Surface Barrier: Design basis document

    International Nuclear Information System (INIS)

    The Hanford Site Surface Barrier Development Program (BDP) was organized in 1985 to develop the technology needed to provide a long-term surface barrier capability for the Hanford Site and other arid sites. This document provides the basis of the prototype barrier. Engineers and scientists have momentarily frozen evolving barrier designs and incorporated the latest findings from BDP tasks. The design and construction of the prototype barrier has required that all of the various components of the barrier be brought together into an integrated system. This integration is particularly important because some of the components of the protective barreir have been developed independently of other barreir components. This document serves as the baseline by which future modifications or other barrier designs can be compared. Also, this document contains the minutes of meeting convened during the definitive design process in which critical decisions affecting the prototype barrier's design were made and the construction drawings

The estimated time to limit display is designed to help operators restore levels or pressures before automatic or required manual actions are activated.

  2. U.S. ALMR prototype project plan

    International Nuclear Information System (INIS)

    The ALMR Program, with its modular reactor design, has adopted a prototype project as the quickest and lowest cost approach to obtaining design certification. One nuclear island can be built for a fraction of the cost of a complete plant, and subjected to a series of tests to demonstrate safety characteristics. A non-safety related turbine island can then be added, permitting demonstration of the prototype as an electrical power producer, and permitting payback of funding required for construction and operation of the prototype. Based on the results of these tests, a standard plant design certification can be obtained assuring licensability of the commercial ALMR prior to utility commitment of resources for the first full size commercial plant.

    Full Text Available Theories of natural language and concepts have been unable to model the flexibility, creativity, context-dependence, and emergence, exhibited by words, concepts and their combinations. The mathematical formalism of quantum theory has instead been successful in capturing these phenomena such as graded membership, situational meaning, composition of categories, and also more complex decision making situations, which cannot be modeled in traditional probabilistic approaches. We show how a formal quantum approach to concepts and their combinations can provide a powerful extension of prototype theory. We explain how prototypes can interfere in conceptual combinations as a consequence of their contextual interactions, and provide an illustration of this using an intuitive wave-like diagram. This quantum-conceptual approach gives new life to original prototype theory, without however making it a privileged concept theory, as we explain at the end of our paper.

    Fabrication of micropatterned ceramics or ceramic microparts make high demands on the precision and resolution of the moulding process. As finishing of miniaturised or micropatterned ceramic components is nearly impossible, shaping has to be done by a replication step in the green, unfired state. To avoid high tooling costs in product development, a rapid prototyping process chain has been established that enables rapid manufacturing of ceramic microcomponents from functional models to small lot series within a short time. This process chain combines the fast and inexpensive supply of master models by rapid prototyping with accurate and flexible ceramic manufacturing by low-pressure injection moulding. Besides proper feedstock preparation and sufficient small grain size, the quality of the final components is mainly influenced by the quality of the master model. Hence, the rapid prototyping method must be carefully selected to meet the requirements of the component to be fabricated.

    The SDHCAL technological prototype is a $1 \\times 1 \\times 1.3$~m$^3$ high-granularity Semi-Digital Hadronic CALorimeter using Glass Resistive Plate Chambers as sensitive medium. It is one of the two HCAL options considered by the ILD Collaboration to be proposed for the detector of the future International Linear Collider project. The prototype is made of up to 50 GRPC detectors of 1~m$^2$ size and 3~mm thickness each with an embedded semi-digital electronics readout that is autotriggering and power-pulsed. The GRPC readout is finely segmented into pads of 1~cm$^2$. This proceeding describes the prototype, its operation and its performance in energy reconstruction. Aspects of the GRPC readout modelling and comparisons with simulations are also presented.

    Multi-gap Resistive Plate Chambers (MRPCs) with multi-strip readout are considered to be the optimal detector candidate for the Time-of-Flight (ToF) wall in the Compressed Baryonic Matter (CBM) experiment. In the R&D phase MRPCs with different granularities, low-resistive materials and high voltage stack configurations were developed and tested. Here, we focus on two prototypes called HD-P2 and THU-strip, both with strips of 27 cm$^2$ length and low-resistive glass electrodes. The HD-P2 prototype has a single-stack configuration with 8 gaps while the THU-strip prototype is constructed in a double-stack configuration with 2 $\\times$ 4 gaps. The performance results of these counters in terms of efficiency and time resolution carried out in a test beam time with heavy-ion beam at GSI in 2014 are presented in this proceeding.

  8. HSI Prototypes for Human Systems Simulation Laboratory

    International Nuclear Information System (INIS)

    This report describes in detail the design and features of three Human System Interface (HSI) prototypes developed by the Institutt for Energiteknikk (IFE) in support of the U.S. Department of Energy's Light Water Reactor Sustainability Program under Contract 128420 through Idaho National Laboratory (INL). The prototypes are implemented for the Generic Pressurized Water Reactor simulator and installed in the Human Systems Simulation Laboratory at INL. The three prototypes are: 1) Power Ramp display 2) RCS Heat-up and Cool-down display 3) Estimated time to limit display The power ramp display and the RCS heat-up/cool-down display are designed to provide good visual indications to the operators on how well they are performing their task compared to their target ramp/heat-up/cool-down rate. The estimated time to limit display is designed to help operators restore levels or pressures before automatic or required manual actions are activated.

    The age of secondary forests in the Amazon will become more critical with respect to the estimation of biomass and carbon budgets as tropical forest conversion continues. Multitemporal Thematic Mapper data were used to develop land cover histories for a 33,000 Square kM area near Ariquemes, Rondonia over a 7 year period from 1989-1995. The age of the secondary forest, a surrogate for the amount of biomass (or carbon) stored above-ground, was found to be unimportant in terms of biomass budget error rates in a forested TM scene which had undergone a 20% conversion to nonforest/agricultural cover types. In such a situation, the 80% of the scene still covered by primary forest accounted for over 98% of the scene biomass. The difference between secondary forest biomass estimates developed with and without age information were inconsequential relative to the estimate of biomass for the entire scene. However, in futuristic scenarios where all of the primary forest has been converted to agriculture and secondary forest (55% and 42% respectively), the ability to age secondary forest becomes critical. Depending on biomass accumulation rate assumptions, scene biomass budget errors on the order of -10% to +30% are likely if the age of the secondary forests are not taken into account. Single-date TM imagery cannot be used to accurately age secondary forests into single-year classes. A neural network utilizing TM band 2 and three TM spectral-texture measures (bands 3 and 5) predicted secondary forest age over a range of 0-7 years with an RMSE of 1.59 years and an R(Squared) (sub actual vs predicted) = 0.37. A proposal is made, based on a literature review, to use satellite imagery to identify general secondary forest age groups which, within group, exhibit relatively constant biomass accumulation rates.

    Using the vectorial diffraction theory established by Richards and Wolf, we demonstrate that the resolution of a two-photon microscope can be improved with a radially polarized TM01 laser beam and an interface between dielectrics, instead of the linearly polarized Gaussian beam already used in laser scanning microscopy. To verify the theoretical results, we developed a mode converter producing radially polarized beams and we have integrated it in a commercial two-photon microscope.

  16. Forest attributes estimation using aerial laser scanner and TM data

    Energy Technology Data Exchange (ETDEWEB)

    Shataee, S.

    2013-07-01

    Aim of study: The aim of this study was performance of four non-parametric algorithms including the k-NN, SVR, RF and ANN to estimate forest volume and basal area attributes using combination of Aerial Laser Scanner and Landsat- TM data. Area of study: Data in small part of a mixed managed forest in the Waldkirch region, Germany. Material and methods: The volume/ha and basal area/ha in the 411 circular plots were estimated based on DBH and height of trees using volume functions of study area. The low density ALS raw data as first and last pulses were prepared and automatically classified into vegetation and ground returns to generate two fine resolution digital terrain and surface models after noise removing. Plot-based height and density metrics were extracted from ALS data and used both separated and combined with orthorectified and processed TM bands. The algorithms implemented with different options including k-NN with different distance measures, SVR with the best regularized parameters for four kernel types, RF with regularized decision tree parameters and ANN with different types of networks. The algorithm performances were validated using computing absolute and percentage RMSe and bias on unused test samples. Main results: Results showed that among four methods, SVR using the RBF kernel could better estimate volume/ha with lower RMSe and bias (156.02 m{sup 3} ha{sup -}1 and 0.48, respectively) compared to others. In basal area/ha, k-NN could generate results with similar RMSe (11.79 m{sup 3} ha{sup -}1) but unbiased (0.03) compared to SVR with RMSe of 11.55 m{sup 3} ha{sup -}1 but slightly biased (-1.04). Research highlights: Results exposed that combining Lidar with TM data could improve estimations compared to using only Lidar or TM data. (Author)

  17. Augmenting Forest Stand Parameters using Landsat TM Spectral Images

    Forest stand parameters, such as diameter at breast height (DBH), tree height (H), or volume per hectare (V), are imperative for forest resources assessment. Traditional inventory of forest stand parameters, usually based on fieldwork, is often difficult, time-consuming, and expensive, to conduct in large areas. Therefore, estimating forest stand parameters in large areas using traditional inventory approach augmented by satellites data has a significant implication for sustainable forest management and natural resources efficiency. However, obtaining suitable satellite image data for such purpose is a challenging task mainly because of insignificant knowledge between the forest stand parameters and satellite spectral response relationships. Here, we present the use of Landsat Thematic Mapper (TM) spectral responses data for augmenting forest stand parameter obtained from fieldwork at the Lahav Forest, in the Israeli Northern Negev. A new algorithm was developed in order to use all eight TM band when calculating the linear combination which correlates the most to each one of the forest stand parameters. Each linear combination is obtained first for local area inside the entire studied grid and is then fitted using a simple linear polynomial curve to the known forest stand parameter. Once the relationship between the two is characterized by a linear polynomial equation, the TM linear combination local area data is translated to the same equivalent area of the chosen forest stand parameter. At last, we interpolate the entire TM grid using a higher order polynomial fit applied to all the augmented local area combined together to attain full coverage of the desired forest stand parameter.

  18. Mass balance investigation of alpine glaciers through LANDSAT TM data

    Bayr, Klaus J.

    1989-01-01

    An analysis of LANDSAT Thematic Mapper (TM) data of the Pasterze Glacier and the Kleines Fleisskees in the Austrian Alps was undertaken and compared with meteorological data of nearby weather stations. Alpine or valley glaciers can be used to study regional and worldwide climate changes. Alpine glaciers respond relatively fast to a warming or cooling trend in temperature through an advance or a retreat of the terminus. In addition, the mass balance of the glacier is being affected. Last year two TM scenes of the Pasterze Glacier of Aug. 1984 and Aug. 1986 were used to study the difference in reflectance. This year, in addition to the scenes from last year, one MSS scene of Aug. 1976 and a TM scene from 1988 were examined for both the Pasterze Glacier and the Kleines Fleisskees. During the overpass of the LANDSAT on 6 Aug. 1988 ground truthing on the Pasterze Glacier was undertaken. The results indicate that there was considerable more reflectance in 1976 and 1984 than in 1986 and 1988. The climatological data of the weather stations Sonnblick and Rudolfshuette were examined and compared with the results found through the LANDSAT data. There were relations between the meteorological and LANDSAT data: the average temperature over the last 100 years showed an increase of .4 C, the snowfall was declining during the same time period but the overall precipitation did not reveal any significant change over the same period. With the use of an interactive image analysis computer, the LANDSAT scenes were studied. The terminus of the Pasterze Glacier retreated 348 m and the terminus of the Kleines Fleisskees 121 m since 1965. This approach using LANDSAT MSS and TM digital data in conjunction with meteorological data can be effectively used to monitor regional and worldwide climate changes.

  2. Power scaling of end-pumped c-cut Tm:YAP lasers

    International Nuclear Information System (INIS)

    The temperature distributions of a Tm:YAP rod and a Tm:YAP slab were compared theoretically and experimentally. The measured thermal focal length was much longer for a thinner Tm:YAP slab than a Tm:YAP rod and a thicker Tm:YAP slab, indicating weaker thermal effects of a thinner Tm:YAP slab, which was in agreement with the theoretical analysis. Based on thermal effect analysis, laser performance of a c-cut Tm:YAP rod and slab in the dual-end-pumped configuration was compared. Higher slope efficiency and output power were obtained in the slab geometry than in the rod geometry, and the thinner the slab, the better the laser performance. (paper)

  5. Pool boiling performance of NovecTM 649 engineered fluid

    International Nuclear Information System (INIS)

    A new fluorinated ketone, C2F5C(O)CF(CF3)2, is currently being considered as an environmentally friendly alternative for power electronics cooling applications due to its high dielectric strength and low global warming potential (GWP). Sold commercially by the 3M Company as NovecTM 649 Engineered Fluid, C2F5C(O)CF(CF3)2 exhibits very low acute toxicity while maintaining long-term stability. To assess the general two-phase heat transfer performance of NovecTM 649, pool boiling tests were conducted by resistively heating a 0.01 in. diameter nickel wire at the fluid's atmospheric saturation temperature of 49 deg C. The nucleate boiling heat transfer coefficient and critical heat flux (CHF) obtained for the fluorinated ketone compare favorably with results obtained for FC-72, a fluorocarbon widely used for the direct cooling of electronic devices. Initial results indicate that NovecTM 649 may prove to be a viable alternative to FC-72 and other halo alkanes for the cooling of high power density electronic devices. (author)

    2002-01-01

    The selection of prototype patterns plays a decisive part in the performance of synergetic neural network. Amongst the existing prototype pattern selection schemes, the learning algorithm based on information superposition presented by Wang[1] is the most efficient. However, it has a degree parameter greatly affecting the training process to be determined. To overcome this drawback, an improved algorithm is presented and discussed here. This approach makes use of Genetic Algorithm, a stochastic global search method, to search the global optimum of the unknown parameter in a small search space. Therefore, it converges fairly fast. The experimental results also demonstrate its effectivity.

    2010-01-01

    In this paper, we introduce user prototypes as a technique that supports users’ articulation of emotions relevant for design: dreams, fears, motivations – their feelings and aspirations. Following Bateson’s writings about communication through art, we consider user prototypes as “partly unconscious...... communication” and propose to analyze them by focusing on the emotional articulations integrated in the users’ design language. We illustrate this with an example from a design research project on designing learning technology for young diabetics. The example shows how young people with diabetes can express...

    在353 K的尿素-乙酰胺-NaBr-KBr熔体中,用恒电位电解法在Cu基片上制备了稀土RE(Dy,Nd,Eu)-铁族TM(Co)合金膜.利用循环伏安法研究了熔体的电化学行为.电化学实验结果表明,在Pt电极上,Co(Ⅱ)+2e→Co(0)是一步完全的不可逆反应,并测得Co(Ⅱ)在Pt电极上的传递系数a以及扩散系数D0.稀土元素(Dy,Nd,Eu)难以被单独沉积,但能被Co(Ⅱ)诱导共沉积.用EDS分析合金膜的成分及含量.用XRD和振动样品磁强计(VSM)分析样品退火前后的晶相和磁性能变化特征.实验结果表明,合金膜的表面形貌和磁性与其成分组成及沉积电位紧密相关,且稀土离子的被诱导能力取决于稀土与铁族原子之间的电负性差值.%Rare earth ( RE = Dy,Nd,Eu) -3d transition metal ( TM = Co) alloy films were codeposited on copper substrate in urea - acetarnide - NaBr - KBr melt at 355K. The cyclic voltammetry was used to study the electrochemical behavior,showing that the electroreduction of TM was irreversible in one step. The transfer coefficient a and the diffusion coefficient DO of Co2+ were measured. RE3+ could not be reduced alone, but it could be inductively codeposited with Co2+ . The composition of films was analyzed by EDS; the crystalline phases were investigated by XRD; the microstructures were observed by SEM;and the magnetic properties were measured by VSM. The experimental results reveal that, the surface morphologies and the magnetic properties of the RE - TM alloy films depend strongly on the composition and electrodeposition potential, furthermore the RE - induced codeposition ability is dominated by the electronegativity difference between RE and TM atoms.

    International Nuclear Information System (INIS)

    Two-phase nanocomposites of α-Fe and a transition metal (TM) carbide were prepared by mechanical alloying and annealing of elemental Fe80TM10C10 powder blends. The soft magnetic properties remain generally limited (coercivity≥300 A/m), presumably caused by a 'coarse' grain fraction (>20 nm) originating from inhomogeneities in the mechanically alloyed precursor.

    In the CALICE Collaboration are developed calorimeters for a future e{sup +}e{sup -} Linear Collider. One approach is called Particle Flow which requires highly granular calorimeters thus to achieve a jet energy resolution of 3-4%. The CALICE Collaboration is developing concepts and prototypes for Particle Flow optimized calorimeters with various readout technologies. The Analog Hadronic Calorimeter (AHCAL) is one of the concepts based on 3 x 3 cm{sup 2} scintillator tiles with Silicon Photomultipliers. The performance and suitability has been proven in the former physics prototype. The current focus of the second generation engineering prototype is on the full scalability of the detector. In 2014, two test beam periods happened at the PS at CERN, with an iron stack structure designed for the final detector (1 m{sup 3}) and 15 active layers (including 3 ScECAL layers). This talk focuses on the engineering prototype commissioning phase before testbeam, the monitoring of the calorimeter during data taking and a first look into the data taken at the PS.

    TM4SF5 (transmembrane 4 L six family member 5) is involved in EMT (epithelial-mesenchymal transition) for liver fibrosis and cancer metastasis; however, the function(s) of TM4SF5 during embryogenesis remains unknown. In the present study the effects of TM4SF5 on embryogenesis of zebrafish were investigated. tm4sf5 mRNA was expressed in the posterior somites during somitogenesis and in whole myotome 1 dpf (day post-fertilization). tm4sf5 suppression impaired development of the trunk with aberrant morphology of muscle fibres and altered expression of integrin α5. The arrangement and adhesion of muscle cells were abnormally disorganized in tm4sf5 morphants with reduced muscle fibre masses, where integrin α5-related signalling molecules, including fibronectin, FAK (focal adhesion kinase), vinculin and actin were aberrantly localized, compared with those in control fish. Aberrant muscle developments in tm4sf5 morphants were recovered by additional tm4sf5 or integrin α5 mRNA injection. Such a role for TM4SF5 was observed in the differentiation of C2C12 mouse myoblast cells to multinuclear muscle cells. Taken together, the results show that TM4SF5 controls muscle differentiation via co-operation with integrin α5-related signalling. PMID:24897542

  13. Initial Usability Testing of a Hand-held Electronic Logbook Prototype for the Human Research Facility

    1996-01-01

    The Apple(R) Newton(TM) MessagePad 110 was flown aboard the KC-135 reduced gravity aircraft for microgravity usability testing. The Newton served as the initial hand-held electronic logbook prototype for the International Space Station (ISS) Human Research Facility (HRF). Subjects performed three different tasks with the Newton: (1) using the stylus to tap on different sections of the screen in order to launch an application and to select options within it; (2) using the stylus to write, and; (3) correcting handwriting recognition errors in a handwriting-intensive application. Subjects rated handwriting in microgravity 'Borderline' and had great difficulties finding a way in which to adequately restrain themselves at the lower body in order to have their hands free for the Newton. Handwriting recognition was rated 'Unacceptable,' but this issue is hardware-related and not unique to the microgravity environment. It is suggested that the restraint and handwriting issues are related and require further joint research with the current Handheld Electronic Logbook prototype: the Norand Pen*key Model #6300.

  14. Prototype Design of Plasma-Nitriding Apparatus for Components of Industries

    International Nuclear Information System (INIS)

    An apparatus to carry-out plasma-nitriding surface treatment has been designed. The construction was planned as a prototype for a larger system at industrial scale. The design was based on a similar apparatus currently operating at the Accelerator Laboratory at the P3TM-BATAN, in Yogyakarta. The system consists of a main vacuum chamber from steel SS-304, 45 cm OD, 55 cm height and is equipped with a nitriding chamber in the inner part that also functions as a plasma container (Quartz, cylindrical, 38 cm OD, 40 cm height). The system utilized an anode-cathode pair to generate nitrogen plasma, as well as to accelerate and direct the positively-charged-plasma toward the surface of the material to be treated. The pressure inside the chamber is designed to be in the region of 10-3 mb with a temperature between 350-590 oC. Pulsated DC high voltage can be set at 1-50 kV at a frequency between 100-1000 Hz and current 1- 50 mA. The safety and reliability features have been designed to obtain nitriding results that are in accordance with the required technical specification as well as economical constrain. It is hoped that this device can become a prototype for future development of an industrial scale plasma-nitriding apparatus. (author)

    2008-01-01

    The ultraviolet upconversion luminescence of Tm3+ ions sensitized by Yb3+ ions in oxyfluoride nanophase vitroceramics when excited by a 975 nm diode laser was studied. An ultraviolet upconversion luminescence line positioned at 363.6 nm was found. It was attributed to the fluorescence transition of 1D2→3H6 of Tm3+ ion. Sev- eral visible upconversion luminescence lines at 450.7 nm, (477.0 nm, 462.5 nm), 648.5 nm, (680.5 nm, 699.5 nm) and (777.2 nm, 800.7 nm) were also found, which result respectively from the fluorescence transitions of 1D2→3F4, 1G4→3H6, 1G4→3F4, 3F3→3H6 and 3H4→3H6 of Tm3+ ion. The careful measurement and analysis of the variation of upconversion luminescence intensity F as a function of the 975 nm pumping laser power P prove that the upconversion luminescence of 1D2 state is partly a five-photon upconversion luminescence, and the upconversion lumines- cence of 1G4 state and 3H4 state are respectively the three-photon and two-photon upconversion luminescence. The theoretical analysis suggested that the upcon- version mechanism of the 363.6 nm 1D2→3H6 upconversion luminescence is partly the cross energy transfer of {3H4(Tm3+)→3F4(Tm3+), 1G4(Tm3+)→1D2(Tm3+)} and {1G4(Tm3+)→3F4(Tm3+), 3H4(Tm3+)→1D2(Tm3+)} between Tm3+ ions. In addition, the upconversion luminescence of 1G4 and 3H4 state results respectively from the se- quential energy transfer {2F5/2(Yb3+)→2F7/2(Yb3+), 3H4(Tm3+)→1G4(Tm3+)} and {2F5/2(Yb3+) →2F7/2(Yb3+), 3F4(Tm3+)→3F2(Tm3+)} from Yb3+ ions to Tm3+ ions.

  16. NobleChemTM for commercial power plant application

    International Nuclear Information System (INIS)

    NoblechemTM is a GE patented technology that has been applied in 26 operating BWRs worldwide for potential IGSCC mitigation of reactor internal components, when used along with low levels of hydrogen in the feedwater. The technology demonstrates a method of utilizing hydrogen water chemistry (HWC) more effectively by using the extraordinary catalytic activity of noble metals to react hydrogen and oxygen. The addition of hydrogen gas to the feedwater of a BWR, was developed in the 1980's to mitigate the stress corrosion cracking propensity of BWR structural materials. The specification for HWC recommends establishing an electrochemical corrosion potential (ECP) of -230 mV(SHE) or less on the component of interest. Unfortunately, meeting this specification in BWR reactor internal components results in a significant increase in the radiation levels in the main steam. The accompanying operating dose rate is unacceptable for many utilities and thus moderate HWC (1 to 1.6 ppm hydrogen in the feedwater) has not been widely adapted. Unlike BWR structural materials, which only reach the ECP specification of -230 mV(SHE) at low bulk concentrations of reactor water oxidants (oxygen and hydrogen peroxide), noble metal treated surfaces respond to the molar ratio of hydrogen to total oxidants which is attained at very low hydrogen levels, with little or no long-term increase in main steam radiation levels. NoblechemTM takes advantage of this catalytic property by incorporating a thin deposit of platinum and rhodium on structural surfaces. This paper briefly describes the process of NobleChemTM application and the knowledge gained from the extensive experience from 26 BWRs over the past 5 years. (authors)

    2001-01-01

    LaRC(TM)-PETI-5 is a PhenylEthynyl-Terminated Imide resin developed at NASA Langley Research Center (LaRC) during the 1990s. It offers a combination of attractive composite and adhesive properties. IM7/LaRC(TM)-PETI-5 composites exhibit thermal and thermo-oxidative stability typical of polyimides, superior chemical resistance and processability, excellent mechanical properties, toughness and damage tolerance. It was selected for study in the High Speed Research program aimed at developing technologies for a future supersonic aircraft, the High Speed Civil Transport, with a projected life span of 60 000 h at a cruise speed up to Mach 2.4. Robust autoclave processing cycles for LaRC(TM)-PETI-5 composites have been thoroughly designed and demonstrated, which involved hand lay-up of solvent-ladened 'wet' prepregs. However, this type of processing is not only costly but also environmentally unfriendly. Volatile management and shrinkage could become serious problems in the fabrication of large complex airframe structural subcomponents. Robotic tow placement technology utilizing 'dry' material forms represents a new fabrication process which overcomes these deficiencies. This work evaluates and compares mechanical properties of composites fabricated by heated head automated tow placement (dry process) with those obtained by hand lay-up/autoclave fabrication (wet process). Thermal and rheological properties of the robotically as-placed uncured composites were measured. A post-cure cycle was designed due to the requirement of the PETI-5 resin for a 370 C/1 h hold to reach full cure, conditions which cannot be duplicated during heated head robotic placement. Mechanical properties such as 0 degree flexural strength and modulus, open hole tensile and compressive strength and moduli, reduced section compression dogbone compressive strength, and modified zippora-medium small (MZ-MS) tensile and compressive properties were obtained on the post-cured panels. These properties

    2012-12-31

    The original project scope that was established in 2007 aimed to install a 1,700 meter (1.1 mile) medium voltage HTS Triax{TM} cable system into the utility grid in New Orleans, LA. In 2010, however, the utility partner withdrew from the project, so the 1,700 meter cable installation was cancelled and the scope of work was reduced. The work then concentrated on the specific barriers to commercialization of HTS cable technology. The modified scope included long-length HTS cable design and testing, high voltage factory test development, optimized cooling system development, and HTS cable life-cycle analysis. In 2012, Southwire again analyzed the market for HTS cables and deemed the near term market acceptance to be low. The scope of work was further reduced to the completion of tasks already started and to testing of the existing HTS cable system in Columbus, OH. The work completed under the project included: • Long-length cable modeling and analysis • HTS wire evaluation and testing • Cable testing for AC losses • Optimized cooling system design • Life cycle testing of the HTS cable in Columbus, OH • Project management. The 200 meter long HTS Triax{TM} cable in Columbus, OH was incorporated into the project under the initial scope changes as a test bed for life cycle testing as well as the site for an optimized HTS cable cooling system. The Columbus cable utilizes the HTS TriaxTM design, so it provided an economical tool for these of the project tasks.

    Quasi hydrostatic pressure measurements of the resistivity of a single crystal of TmS are reported. The resistivity rho is reduced by pressure P over the full range studied (up to 28 kbar and down to liquid He). It goes through a maximum near 10 K and decreases logarithmically for higher temperatures. Both this behavior and the reduction of the InT slope by P can be explained in a model of resonant scattering as previously done for Ce compounds. The Neel temperature Tsub(N), marked by a small anomaly in rho, increases with P in accordance with previous susceptibility results.

    Tm-doped Ba{sub 0.8}Sr{sub 0.2}TiO{sub 3} thick films were prepared by the screen-printing technique on the alumina substrate. The microstructure of the Tm-doped BST thick films was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectroscopy, respectively. All the samples showed a typical perovskite polycrystalline structure when sintered at 1260 Degree-Sign C. The substitution behavior of Tm{sup 3+} ion in BST was found to change with increasing the Tm{sup 3+} concentration. The observed Tm-related red emission reaches the maximum at 0.2 mol% Tm{sup 3+} concentration. The effects of concentration quenching on the luminescence intensity were discussed.

    Directory of Open Access Journals (Sweden)

    B. Porfidia

    1997-06-01

    Full Text Available A new 222Rn monitoring prototype has been designed, assembled and tested at the Istituto Nazionale di Geofisica (ING specifically addressed to seismic surveillance tasks, exploiting environmental monitoring, etc. It operates with an a scintillation technique (photomultiplier + Lucas Cell coupled with a water input system, that lets continuous dehumidified gas flow, stripped from groundwater under monitoring. Several laboratory tests have been carried out to check the stability and versatility of the system; moreover statistical tests have been accomplished on several data sets obtained with an 241Am radioactive standard source, to check stability of the photomultiplier. A customised water flow system has been developed to perform both the highest efficiency and lowest influence of external noise parameters. This new prototype is very cheap and will be integrated within the new multiparametric geochemical monitoring system GMS II, that is currently being developed at ING, specifically designed for geochemical surveillance of seismic events.

  9. Laser prototyping of printed circuit boards

    Nowak, M. R.; Antończak, A. J.; Kozioł, P. E.; Abramski, K. M.

    2013-09-01

    This paper describes the application of laser micromachining to rapid prototyping of printed circuit boards (PCB) using nano-second lasers: the solid-state Nd:YAG (532/1064 nm) laser and the Yb:glass fiber laser (1060 nm). Our investigations included tests for various mask types (synthetic lacquer, light-sensitive emulsion and tin). The purpose of these tests was to determine some of the basic parameters such as the resolution of PCB prototyping, speed of processing and quality of PCB mapping with commonly available laser systems. Optimization of process parameters and the proposed conversion algorithm have allowed us to produce circuit boards with a resolution similar to that of the Laser Direct Imaging (LDI) technology.

  10. The LUX prototype detector: Heat exchanger development

    International Nuclear Information System (INIS)

    The LUX (large underground xenon) detector is a two-phase xenon time projection chamber (TPC) designed to search for WIMP–nucleon dark matter interactions. As with all noble element detectors, continuous purification of the detector medium is essential to produce a large (>1ms) electron lifetime; this is necessary for efficient measurement of the electron signal which in turn is essential for achieving robust discrimination of signal from background events. In this paper, we describe the development of a novel purification system deployed in a prototype detector. The results from the operation of this prototype indicated heat exchange with an efficiency above 94% up to a flow rate of 42 slpm, allowing for an electron drift length greater than 1 m to be achieved in approximately 2 days and sustained for the duration of the testing period

  11. Fermilab site-fillers as CAMEL prototypes

    International Nuclear Information System (INIS)

    At Snowmass, beam energies greater than about 10 TeV dominated the intellectual efforts related to hadron-hadron colliders. The anticipated cost and scope of these machines spurred the search for cost-cutting innovations and for a suitable site, perhaps in the southwestern desert. (Given its probable location and method of design, CAMEL seems an appropriate acronym for such a facility.) A prototype of more modest time-scale, cost, and energy is needed to bridge the physics gap until completion of CAMEL and to establish the feasibility of various proposed technologies. Building a prototype at Fermilab would reduce its cost, speed its completion, and improve its performance by taking advantage of existing real estate and expertise and by exploiting fully the potential capabilities of existing facilities (injectors, antiproton accumulator, etc.). The design and expected performance of various Fermilab site-filling (R = 2.4 km) antiproton-proton colliders are discussed. Other options are also described

    2016-01-01

    In the last 30 years numerous attempts have been made to improve the efficiency of the parabolic collectors in the electric power production, although most of the studies have focused on the industrial production of thermoelectric power. This research focuses on the application of this concentrating solar thermal power in the unexplored field of building construction. To that end, a mechatronic prototype of a hybrid paraboloidal and cylindrical-parabolic tracker based on the Arduido technology has been designed. The prototype is able to measure meteorological data autonomously in order to quantify the energy potential of any location. In this way, it is possible to reliably model real commercial equipment behavior before its deployment in buildings and single family houses. PMID:27314359

  13. Aging studies of CMS muon chamber prototypes

    International Nuclear Information System (INIS)

    Aging of CMS muon cathode strip chamber prototypes under sustained irradiation was studied. The tests were performed with three prototypes of different gas seal designs and with three gas mixtures Ar(30%)+CO2(50%)+CF4(20%), Ar(30%)+CO2(70%) and Ar(40%)+CO2(50%)+CF4(10%). The CF4-containing mixtures showed no or little aging for an overall accumulated charge per unit of wire length in excess of 13 C/cm. In comparison, the performance deterioration in the Ar-CO2 mixture proved to be very dramatic: the gas gain falls by a factor of 2 for each 0.25 C/cm of accumulated charge

  14. Fresnel Interferometric Imager: ground-based prototype

    CERN Document Server

    Serre, Denis; Koechlin, Laurent

    2009-01-01

    The Fresnel Interferometric Imager is a space-based astronomical telescope project yielding milli-arc second angular resolution and high contrast images with loose manufacturing constraints. This optical concept involves diffractive focusing and formation flying: a first "primary optics" space module holds a large binary Fresnel Array, and a second "focal module" holds optical elements and focal instruments that allow for chromatic dispersion correction. We have designed a reduced-size Fresnel Interferometric Imager prototype and made optical tests in our lab, in order to validate the concept for future space missions. The Primary module of this prototype consists of a square, 8 cm side, 23 m focal length Fresnel array. The focal module is composed of a diaphragmed small telescope used as "field lens", a small cophased diverging Fresnel Zone Lens (FZL) that cancels the dispersion and a detector. An additional module collimates the artificial targets of various shapes, sizes and dynamic ranges to be imaged. In...

  15. Regional adaptive delaminating algorithm for rapid prototyping

    CAI Daosheng; SHI Yusheng; HUANG Shuhuai

    2005-01-01

    With the development of rapid prototyping (RP) technology, the contradiction between fabricating speed and precision becomes more and more acute. In order to solve the contradiction, a regional effective adaptive delaminating algorithm is proposed in this paper. It is different from the traditional method that the regional adaptive delaminating method divides slicing contours into several regions and adaptively delaminates in respective region only according to the contours information. Namely, this method can not only adaptively delaminate at different height of CAD model but also adaptively delaminate different regions in one slicing layer. Furthermore, because the two-dimensional contour data adopted in this method are necessary for rapid prototyping system, this regional effective adaptive delaminating method is suitable for all RP systems. A comparative study is used to analyze the effectiveness of this method, which can demonstrate that this method can increase the fabricating speed and reduce the running cost under the condition of ensuring fabricating precision.

  16. Prototype-based models in machine learning.

    Science.gov (United States)

    Biehl, Michael; Hammer, Barbara; Villmann, Thomas

    2016-01-01

    An overview is given of prototype-based models in machine learning. In this framework, observations, i.e., data, are stored in terms of typical representatives. Together with a suitable measure of similarity, the systems can be employed in the context of unsupervised and supervised analysis of potentially high-dimensional, complex datasets. We discuss basic schemes of competitive vector quantization as well as the so-called neural gas approach and Kohonen's topology-preserving self-organizing map. Supervised learning in prototype systems is exemplified in terms of learning vector quantization. Most frequently, the familiar Euclidean distance serves as a dissimilarity measure. We present extensions of the framework to nonstandard measures and give an introduction to the use of adaptive distances in relevance learning. PMID:26800334

    A pre-package prototype unit is described having domestic hot water and room solar heating capability that uses air as the collector fluid. This system is designed to be used with a small single-family dwelling where a roof mounted collector array is not feasible. The prototype unit is an assembly containing 203 square feet of effective collector surface with 113 cubic feet of rock storage. The design of structure and storage is modular, which permits expansion and reduction of the collector array and storage bed in 68 square feet and 37 cubic feet increments respectively. The system is designed to be transportable. This permitted assembly and certification testing in one area and installation in another area without tear down and reassembly. Design, installation, operation, performance and maintenance of this system are described.

  17. DOE`s annealing prototype demonstration projects

    Energy Technology Data Exchange (ETDEWEB)

    Warren, J.; Nakos, J.; Rochau, G.

    1997-02-01

    One of the challenges U.S. utilities face in addressing technical issues associated with the aging of nuclear power plants is the long-term effect of plant operation on reactor pressure vessels (RPVs). As a nuclear plant operates, its RPV is exposed to neutrons. For certain plants, this neutron exposure can cause embrittlement of some of the RPV welds which can shorten the useful life of the RPV. This RPV embrittlement issue has the potential to affect the continued operation of a number of operating U.S. pressurized water reactor (PWR) plants. However, RPV material properties affected by long-term irradiation are recoverable through a thermal annealing treatment of the RPV. Although a dozen Russian-designed RPVs and several U.S. military vessels have been successfully annealed, U.S. utilities have stated that a successful annealing demonstration of a U.S. RPV is a prerequisite for annealing a licensed U.S. nuclear power plant. In May 1995, the Department of Energy`s Sandia National Laboratories awarded two cost-shared contracts to evaluate the feasibility of annealing U.S. licensed plants by conducting an anneal of an installed RPV using two different heating technologies. The contracts were awarded to the American Society of Mechanical Engineers (ASME) Center for Research and Technology Development (CRTD) and MPR Associates (MPR). The ASME team completed its annealing prototype demonstration in July 1996, using an indirect gas furnace at the uncompleted Public Service of Indiana`s Marble Hill nuclear power plant. The MPR team`s annealing prototype demonstration was scheduled to be completed in early 1997, using a direct heat electrical furnace at the uncompleted Consumers Power Company`s nuclear power plant at Midland, Michigan. This paper describes the Department`s annealing prototype demonstration goals and objectives; the tasks, deliverables, and results to date for each annealing prototype demonstration; and the remaining annealing technology challenges.

    The piecewise-linear dynamic attenuator has been proposed as a mechanism in CT scanning for personalizing the x-ray illumination on a patient- and application-specific basis. Previous simulations have shown benefits in image quality, scatter, and dose objectives. We report on the first prototype implementation. This prototype is reduced in scale and speed and is integrated into a tabletop CT system with a smaller field of view (25 cm) and longer scan time (42 s) compared to a clinical system. Stainless steel wedges were machined and affixed to linear actuators, which were in turn held secure by a frame built using rapid prototyping technologies. The actuators were computer-controlled, with characteristic noise of about 100 microns. Simulations suggest that in a clinical setting, the impact of actuator noise could lead to artifacts of only 1 HU. Ring artifacts were minimized by careful design of the wedges. A water beam hardening correction was applied and the scan was collimated to reduce scatter. We scanned a 16 cm water cylinder phantom as well as an anthropomorphic pediatric phantom. The artifacts present in reconstructed images are comparable to artifacts normally seen with this tabletop system. Compared to a flat-field reference scan, increased detectability at reduced dose is shown and streaking is reduced. Artifacts are modest in our images and further refinement is possible. Issues of mechanical speed and stability in the challenging clinical CT environment will be addressed in a future design. PMID:27284705

  20. Prototyping Cognitive Prosthetics for People with Dementia

    Davies, Richard; Nugent, Chris D.; Donnelly, Mark

    In the COGKNOW project, a cognitive prosthetic has been developed through the application of Information and Communication Technology (ICT)-based services to address the unmet needs and demands of persons with dementia. The primary aim of the developed solution was to offer guidance with conducting everyday activities for persons with dementia. To encourage a user-centred design process, a three-phased methodology was introduced to facilitate cyclical prototype development. At each phase, user input was used to guide the future development. As a prerequisite to the first phase of development, user requirements were gathered to identify a small set of functional requirements from which a number of services were identified. Following implementation of these initial services, the prototype was evaluated on a cohort of users and, through observing their experiences and recording their feedback, the design was refined and the prototype redeveloped to include a number of additional services in the second phase. The current chapter provides an overview of the services designed and developed in the first two phases.

    1997-01-01

    Participants of the IEC Workshop for the Production of OHP Material on Reproductive Health for Adolescents and Young Adults held November 25-30 in Japan developed innovative, visually appealing overhead projector (OHP) transparencies to serve as prototype information, education, and communication (IEC) materials for the Asian Region. The materials cover a wide range of topics from early marriage to unwanted pregnancy. This paper briefly describes the prototypes. One group focused upon early marriage, an issue of considerable importance to the health and welfare of young women in countries such as Bhutan, India, and Nepal. Participants from China, Laos, Malaysia, and Thailand focused upon the issue of gender equality, while a third group developed OHP material to teach a range of issues related to young people's sexual and reproductive health. Finally, the fourth group, drawn from Indonesia, the Philippines, and Vietnam, focused upon the topic of menstruation with a prototype targeted to boys and girls aged 9-14 years. Boys were included to foster their understanding of menstruation as a natural phenomenon. PMID:12292051

    A 10 m prototype interferometer facility is currently being set up at the AEI in Hannover, Germany. The prototype interferometer will be housed inside a 100 m{sup 3} ultra-high vacuum envelope. Seismically isolated optical tables inside the vacuum system will be interferometrically interconnected via a suspension platform interferometer. Advanced isolation techniques will be used, such as inverted pendulums and geometrical anti-spring filters in combination with multiple-cascaded pendulum suspensions, containing an all-silica monolithic last stage. The light source is a 35 W Nd:YAG laser, geometrically filtered by passing it through a photonic crystal fibre and a rigid pre-modecleaner cavity. Laser frequency stabilisation will be achieved with the aid of a high finesse suspended reference cavity in conjunction with a molecular iodine reference. Coating thermal noise will be reduced by the use of Khalili cavities as compound end mirrors. Data acquisition and control of the experiments is based on the AdvLIGO digital control and data system. The aim of the project is to test advanced techniques for GEO 600 as well as to conduct experiments in macroscopic quantum mechanics.

  3. The AEI 10 m prototype interferometer

    International Nuclear Information System (INIS)

    A 10 m prototype interferometer facility is currently being set up at the AEI in Hannover, Germany. The prototype interferometer will be housed inside a 100 m3 ultra-high vacuum envelope. Seismically isolated optical tables inside the vacuum system will be interferometrically interconnected via a suspension platform interferometer. Advanced isolation techniques will be used, such as inverted pendulums and geometrical anti-spring filters in combination with multiple-cascaded pendulum suspensions, containing an all-silica monolithic last stage. The light source is a 35 W Nd:YAG laser, geometrically filtered by passing it through a photonic crystal fibre and a rigid pre-modecleaner cavity. Laser frequency stabilisation will be achieved with the aid of a high finesse suspended reference cavity in conjunction with a molecular iodine reference. Coating thermal noise will be reduced by the use of Khalili cavities as compound end mirrors. Data acquisition and control of the experiments is based on the AdvLIGO digital control and data system. The aim of the project is to test advanced techniques for GEO 600 as well as to conduct experiments in macroscopic quantum mechanics. Reaching standard quantum-limit sensitivity for an interferometer with 100 g mirrors and subsequently breaching this limit, features most prominently among these experiments. In this paper we present the layout and current status of the AEI 10 m Prototype Interferometer project.

  4. ITER prototype fast plant system controller

    International Nuclear Information System (INIS)

    ITER CODAC Design identified the need for slow and fast control plant systems, based respectively on industrial automation technology with maximum sampling rates below 100 Hz, and on embedded technology with higher sampling rates and more stringent real-time requirements. The fast system is applicable to diagnostics and plant systems in closed-control loops whose cycle times are below 1 ms. Fast controllers will be dedicated industrial controllers with the ability to supervise other fast and/or slow controllers, interface to actuators and sensors and high performance networks (HPN). This contribution presents the engineering design of two prototypes of a fast plant system controller (FPSC), specialized for data acquisition, constrained by ITER technological choices. This prototyping activity contributes to the Plant Control Design Handbook (PCDH) effort of standardization, specifically regarding fast controller characteristics. The prototypes will be built using two different form factors, PXIe and ATCA, with the aim of comparing the implementations. The presented solution took into consideration channel density, synchronization, resolution, sampling rates and the needs for signal conditioning such as filtering and galvanic isolation. The integration of the two controllers in the standard CODAC environment is also presented and discussed. Both controllers contain an EPICS IOC providing the interface to the mini-CODAC which will be used for all testing activities. The alpha version of the FPSC is also presented.

    This paper presents the concept and prototype demonstration results of a new sleeve muscle actuator,which provides a significantly improved performance through a fundamental structural change to the traditional pneumatic muscle.Specifically,the sleeve muscle incorporates a cylindrical insert to the center of the pneumatic muscle,and thus eliminates the central portion of the intemal volume.Through the analysis of the actuation mechanism,it is shown that the sleeve muscle is able to provide a consistent increase of force capacity over the entire range of motion.Furthermore,the sleeve muscle provides a significant energy saving effect,as a result of the reduced internal volume as well as the enhance force capacity.To demonstrate this new concept,a sleeve muscle prototype was designed and fabricated.Experiments conducted on the prototype verified the improvement in the force capacity and demonstrated a significant energy saving effect (20%-37%).Finally,as the future work on this new concept,the paper presents a new robotic elbow design actuated with the proposed sleeve muscle.This unique design is expected to provide a highly compact and powerful actuation approach for robotic systems.

  8. First-principles study of one-dimensional sandwich wires [(P)5TM]∞ (TM = Ti, V, Cr, Mn, Fe, Co)

    International Nuclear Information System (INIS)

    Since the discovery of ferrocene, many one-dimensional metallic sandwich molecular wires have been identified. However, most of the known systems are assembled from organic molecules. Suffering from many drawbacks has, however, hampered their widespread applications. With the goal of breaking this logjam, we provide a blueprint for the designing of a variety of novel sandwich molecular wires ([(P)5TM]∞, TM = Ti, V, Cr, Mn, Fe, and Co) assembled from ferrocene-like inorganic molecules (P)5TM, offering evidence of the existence of inorganic molecular wires in this class. We present first-principles calculations to investigate systematically the electronic and magnetic properties of such novel inorganic sandwich molecular wires. Compared with the organic molecular wires, all the inorganic [(P)5TM]∞ wires are of large magnetic moment. Among them, we find that [(P)5V]∞, [(P)5Cr]∞ and [(P)5Mn]∞ display ferromagnetic character, while for [(P)5Ti]∞, [(P)5Fe]∞ and [(P)5Co]∞, the magnetic coupling is antiferromagnetic. More remarkably, the TM atoms distributed in these wires show regular docking and lead to structures with ordered spin signals, which is a long-term dream of spintronics. We propose that the difference in magnetic coupling for the studied systems is related to the competition between two exchange interactions of TM atoms. Specifically, we propound that the general mechanism for the formation of stable 1D [(P)5TM]∞ involves the transfer of one electron from the TM atom to the P5 ligand forming (P)5- and TM+ alternating structure.

    2002-02-16

    Recently, we have reported a neutron diffraction study in which a striking magnetic behaviour of TmIn{sub 3} was observed. Namely in contrast to earlier bulk measurements, the powder sample of TmIn{sub 3} used in the neutron diffraction experiment revealed an unexpectedly high Neel temperature of {approx}3.2 K as compared to 1.6 K or 1.45 K determined from the heat capacity measurements. Moreover, in the whole temperature range 0.25-3.2 K the coexistence of two magnetic phases described by the propagation vectors k{sub 1} = {l_brace}0, 0, 1/2{r_brace} and k{sub 2} = {l_brace}1/2, 1/2, 0{r_brace} was observed, although no visible deformation of the crystal lattice could be detected. We have attributed this effect to unreleased strains which occurred after crushing and powdering the polycrystalline ingots. Indeed, the low-temperature susceptibility study performed later on two test samples proved that the sample with unreleased strains exhibits drastically different magnetic properties. Therefore it was of interest to examine how the annealing process influences the long-range magnetic ordering in comparison to the one with unreleased strains studied earlier. (orig.)

  13. PLUS7TM Growth Performance after Three Cycle Irradiation

    International Nuclear Information System (INIS)

    Four lead test assemblies (LTAs) for an advanced nuclear fuel, PLUS7TM, which has firstly been developed in Korea in 2002, was irradiated in cycle 5, 6 and 7 at Ulchin unit 3. The LTAs were reached to fuel assembly burnup of 53,214 MWD/MTU, the maximum fuel rod average burnup of 58,139 MWD/MTU, and the duration of irradiation of 1406 effective full power days (EFPD). Poolside fuel examinations such as visual inspection and accurate measurement were performed in spent fuel pool to confirm the irradiation performance of the advanced fuel after each cycle. Measurement items for the assembly performance due to irradiation were assembly growth, assembly bow, assembly twist, top nozzle-rod gap (for rod growth evaluation), rod-rod gap (for rod bow evaluation), grid width increase. As the effects of deformation, i.e., bow or twist due to irradiation were negligible, the irradiation growths of assembly, rod and grid width are described in this paper. As the result of evaluation related to irradiation growth, PLUS7TM was irradiated successfully without any abnormal phenomenon

  14. Tm3+ activated lanthanum phosphate: a blue PDP phosphor

    International Nuclear Information System (INIS)

    Plasma display panels (PDPs) are gaining attention due to their high performance and scalability as a medium for large format TVs. The performance and life of a PDP strongly depends upon the nature of phosphors. Currently, Eu2+ activated barium magnesium aluminate (BAM) is being used as a blue component. Because of its low life, efforts are being made to explore new blue emitting phosphors. One of the alternatives to BAM is Tm3+ activated lanthanum phosphate (LPTM) phosphor. LPTM phosphor samples are prepared by a solid-state as well as sol-gel process in presence of flux. The phosphor of the present investigation, having uniform and spherical shape particles in the range of 0.1-2 μm, is appropriate for thin phosphor screens required for PDP applications. It exhibits a narrow band emission in the blue region, peaking at 452 nm and also a number of narrow bands in the UV region when excited by 147 and 173 nm radiation from a xenon gas mixture. Various possible transitions responsible for UV and visible emission from Tm3+ ion are presented. These phosphors also exhibit good color saturation and better stability when excited with VUV radiation. To achieve higher brightness, they are blended with other UV excited blue emitting phosphors such as BAM. Results related to morphology, excitation, after glow decay, emission and degradation of these phosphors in the powder form as well as in plasma display panels are presented and discussed

    different microclimate, vegetation, land use, and soils regions to assess the relative importance of these parameters as controls on fluxes and to provide baseline data for predicting potential impacts of future climate and land use change on these fluxes. Critical parameters for hydrological modeling will be included in the measurement design. Although this prototype HO focuses on a porous media system in a humid environment, many of the design aspects are generic and should apply to HOs in other settings (fractured media, arid settings). Another goal of the program is to locate ground-based measurement stations to provide ground referencing for satellite systems. An example application is the use of satellite data (LandSat TM, AVHRR, and MODIS) to estimate ET with comparison to ground-based systems (Eddy Covariance/Bowen Ratio) and scintillometers. The use of Advanced Microwave Scanning Radiometer (AMSR-E) for monitoring soil moisture will also be evaluated using ground-based water content monitoring and field campaigns. Precipitation gauge clusters will be optimally located to evaluate NEXRAD and satellite precipitation data. Understanding the correlation between satellite and ground-based data is essential because spaceborne observations provide spatially and temporally distributed measurements and a framework for scaling local measurements to regional areas. The HO networks will provide valuable information on many aspects of the water cycle to advance our understanding on controls on spatial and temporal variability in fluxes across interfaces.

  20. Optimal co-doping concentrations and dynamics of energy transfer processes for Tm3+-Tb3+ and Tm3+-Eu3+ in LiYF4 crystal hosts

    International Nuclear Information System (INIS)

    The dynamics of energy transfer processes in Tm+3-Tb+3 and Tm3+-Eu+3 co-doped LiYF4 crystal hosts were studied from time-resolved Tm3+ fluorescence analysis to estimate the optimal co-doping concentrations which maximize 1.5 μm laser emission from the 3H4 state of Tm3+. The analysis was carried out by finding a numerical solution to the general master equations that govern non-radiative energy transfer processes in crystalline materials and by using the Monte Carlo technique. Our analysis improves the description of experimental fluorescence decay curves. The predicted optimal co-doping concentrations and laser threshold for these luminescent systems are lower than those reported using traditional models for non-radiative energy transfer processes.

    Er-Tm codoped amorphous aluminum oxide (a-Al2O3) thin films have been prepared by an alternative pulsed laser deposition. The phase structure and the surface of the deposited thin films were characterized by the X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. Effective photoluminescence (PL) in the region of 350-900nm was observed when pumped at 325nm, and the PL performance has been improved by modifying the Tm3+ concentration. With the increasing of [Tm]/[Er] concentration ratio, the intensity of emission of 382nm and 500nm bands was improved effectively while that of 76Snm band increased smoothly. Our results suggest that the resonant energy transfer and cross relaxation between Tm3+ and Er3+ play an important role in the evolution of the luminescent response.

    The thermoelectric properties of ternary Ti10Ru19B8 and quaternary Ti9TM2Ru18B8 (TM: Cr, Mn, Fe, Co, Ni, Cu) compounds were investigated in the temperature range from 373 K to 973 K. They form pseudogaps in the electronic densities of states near the Fermi level, E F, which is suitable for thermoelectric materials. We synthesized crack-free pellet samples using arc-melting followed by spark plasma sintering. A maximum dimensionless figure of merit zT max was 0.09 at 973 K for Ti10Ru19B8 whereas a large power factor of 1.4 mW/m K2 was obtained at that temperature. The phonon thermal conductivity decreased through TM substitutions; however, the power factor also decreased due to an additional electronic density of states originated from TM d-states around E F; that is, excitations of both holes and electrons.

    New manufacturing technologies under the banner of rapid prototyping enable the fabrication of structures close in architecture to biological tissue. In their simplest form, these technologies allow the manufacture of scaffolds upon which cells can grow for later implantation into the body. A more exciting prospect is the printing and patterning in three dimensions of all the components that make up a tissue (cells and matrix materials) to generate structures analogous to tissues; this has been termed bioprinting. Such techniques have opened new areas of research in tissue engineering and regenerative medicine.

    The ILC positron system uses novel helical undulators to create a powerful photon beam from the main electron beam. This beam is passed through a titanium target to convert it into electron-positron pairs. The target is constructed as a 1 m diameter wheel spinning at 2000 RPM to smear the 1 ms ILC pulse train over 10 cm. A pulsed flux concentrating magnet is used to increase the positron capture efficiency. It is cooled to liquid nitrogen temperatures to maximize the flatness of the magnetic field over the 1 ms ILC pulse train. We report on prototyping effort on this system.

    Transverse beam profiles in the Relativistic Heavy-Ion Collider (RHIC) will be measured with ionization profile monitors (IPM's). Each IPM collects and measures the distribution of electrons in the beamline resulting from residual gas ionization during bunch passage. The electrons are swept transversely from the beamline and collected on strip anodes oriented parallel to the beam axis. At each bunch passage the charge pulses are amplified, integrated, and digitized for display as a profile histogram. A prototype detector was tested in the injection line during the RHIC Sextant Test. This paper describes the detector and gives results from the beam tests

  19. Prototype steel-concrete LEP dipole magnet

    CERN Multimedia

    1981-01-01

    The magnetic field needed in the LEP dipole magnets was rather low, of a fraction of tesla. This lead to the conception of a novel yoke structure consisting of stacks of 1.5 mm thick low-carbon steel laminations spaced by 4.1 mm with the spaces filled with concrete. The excitation coils were also very simple: aluminium bars insulated by polyester boxes in this prototype, by glass-epoxy in the final magnets. For details see LEP-Note 118,1978 and LEP-Note 233 1980. See also 8111529,7908528X.

    A spectroscopic study based on photoluminescence spectra and decay time profiles in Tm3+ and Tm3+/Dy3+ doped Zn(PO3)2 glasses is reported. The Tm3+ doped Zn(PO3)2 glass, upon 357 nm excitation, exhibits blue emission with CIE1931 chromaticity coordinates, x = 0.157 and y = 0.030, and color purity of about 96%. Under excitations at 348, 352 and 363 nm, which match with the emissions of AlGaN and GaN based LEDs, the Tm3+/Dy3+ co-doped Zn(PO3)2 glass displays natural white, bluish white and cool white overall emissions, with correlated color temperature values of 4523, 10700 and 7788 K, respectively, depending strongly on the excitation wavelength. The shortening of the Dy3+ emission decay time in presence of Tm3+ suggests that Dy3+→Tm3+ non-radiative energy transfer occurs. By using the Inokuti-Hirayama model, it is inferred that an electric quadrupole-quadrupole interaction might be the dominant mechanism involved in the energy transfer. The efficiency and probability of this energy transfer are 0.12 and 126.70 s-1, respectively.

    Recreational runners have an estimated overuse injury incidence rate of up to 79% and 90% for marathoners. A pre-participation screening tool that can identify risk for injury may help reduce overuse injury in runners. The Functional Movement Screen (FMS(TM)) is a reliable clinical tool used with athletes to help predict injury. To date, the FMS(TM) has not been used with endurance athletes. The purpose of this article is to establish normative FMS(TM) values for distance runners. 45 healthy runners performed the FMS(TM). Descriptive statistics were calculated; independent t-tests were performed to examine the effect of gender, experience and injury on scores. A Chi-square test was used to evaluate whether significant differences in scores exist for any component of the FMS(TM). The mean FMS(TM) score was 13.13±1.8. No significant differences in FMS(TM) scores were found between novice and experienced runners (p=0.71) or runners with a history of injury and those without (p=0.20). While male and female runners did not differ significantly in their total FMS(TM) score (p=0.65), significant differences were found in the deep squat (pscores when testing uninjured distance runners.

    2011-07-01

    In 1997, cutaneous papillomatosis caused by Florida manatee (Trichechus manatus latirostris [Tm]) papillomavirus 1 (TmPV1) was detected in seven captive manatees at the Homosassa Springs Wildlife State Park, Florida, USA, and, subsequently, in two wild manatees from the adjacent Homosassa River. Since then, papillomatosis has been reported in captive manatees housed in other locations, but not in wild animals. To determine TmPV1 antibody prevalence in captive and wild manatees sampled at various locations throughout Florida coastal regions, virus-like particles, composed of the L1 capsid protein of TmPV1, were generated with a baculovirus expression system and used to measure anti-TmPV1 antibodies in an enzyme-linked immunosorbent assay. Serologic analysis of 156 manatees revealed a TmPV1 antibody prevalence of 26.3%, with no significant difference between captive (n=39) and wild (n=117) manatees (28.2% and 25.6%, respectively). No antibody-positive wild animal showed PV-induced cutaneous lesions, whereas papillomatosis was observed in 72.7% of antibody-positive captive manatees. Our data indicate that Florida manatees living in the wild are naturally infected by TmPV1 but rarely show TmPV1-induced papillomatosis. Hence, it appears that the wild population would not be harmed in a case of contact with captive animals without visible lesions and productive infections, which could be thus released into the wild.

  11. Dielectric multilayer waveguides for TE and TM mode matching

    CERN Document Server

    Shyroki, D M; Shyroki, Dzmitry M.; Lavrinenko, Andrei V.

    2003-01-01

    We analyse theoretically for the first time to our knowledge the perfect phase matching of guided TE and TM modes with a multilayer waveguide composed of linear isotropic dielectric materials. Alongside strict investigation into dispersion relations for multilayer systems, we give an explicit qualitative explanation for the phenomenon of mode matching on the basis of the standard one-dimensional homogenization technique, and discuss the minimum number of layers and the refractive index profile for the proposed device scheme. Direct applications of the scheme include polarization-insensitive, intermodal dispersion-free planar propagation, efficient fibre-to-planar waveguide coupling and, potentially, mode filtering. As a self-sufficient result, we present compact analytical expressions for the mode dispersion in a finite, N-period, three-layer dielectric superlattice.

    2004-07-01

    As commercially attractive oil and gas discoveries are found in ever increasing water depths, the associated technical, operational and economic challenges become formidable. Appropriate selection of development architecture is essential for the overall success of a project. To properly address this wide range of development options, ABB has developed a portfolio of various hull forms. The SCF{sup TM} concept is one such hull form for a deep water solution. This paper presents the development of the SCF platform by addressing design issues, model test, product storage, fabrication, quay side integration, transportation, installation, schedule and cost estimate. The SCF concept brings tangible benefits to many of the deep water developments around the globe. The attributes of the SCF concept can commercially benefit deep water developments in Brazil as well as potentially generate in-country fabrication and service opportunities. (author)

  13. Geosiphon(TM) Ground Water Remediation System Hydraulics

    International Nuclear Information System (INIS)

    Two, pilot-scale, GeoSiphon(TM) systems have been installed and tested for the treatment of contaminated ground water at the Savannah River Site (SRS). These systems consisted of an in situ treatment cell located in an area of higher hydraulic head and a siphon connecting the cell to a surface stream at a lower hydraulic head. The siphon induced contaminated ground water flow through a permeable treatment media in the cells and transported the treated water to the discharge points in a surface stream. The hydraulic head available to drive the systems is divided between the head losses associated with the treatment cell and siphon. Six different treatment cell configurations and seven different siphon configurations have been hydraulically evaluated in association with both pilot-scale systems. The results provide valuable guidelines for the design of GeoSiphon systems

    CERN Document Server

    Tamouk, Jamshid; Farmanbar, Mina

    2013-01-01

    This paper attempts to find the most accurate classification method among parallelepiped, minimum distance and chain methods. Moreover, this study also challenges to find the suitable combination of bands, which can lead to better results in case combinations of bands occur. After comparing these three methods, the chain method over perform the other methods with 79% overall accuracy. Hence, it is more accurate than minimum distance with 67% and parallelepiped with 65%. On the other hand, based on bands features, and also by combining several researchers' findings, a table was created which includes the main objects on the land and the suitable combination of the bands for accurately detecting of landcover objects. During this process, it was observed that band 4 (out of 7 bands of Landsat 5TM) is the band, which can be used for increasing the accuracy of the combined bands in detecting objects on the land.

  17. System 80 +TM - design certification of a nuclear power module

    International Nuclear Information System (INIS)

    In order to meet utility needs for the 1990's, Combustion Engineering, Inc., is enhancing its standardized System 80R Nuclear Steam Supply System. The System 80+TM Standard Design will address new licensing issues and meet the needs of utilities for increased public safety, investment protection, operational flexibility, reduced cost, and case of maintenance. C-E is actively involved in a program to obtain certification of this advanced, standardized design by 1991. Design Certification will mean that the vast majority of the regulatory issues are resolved, up front, prior to initiating construction. This, by itself will substantially reduce uncertainties in construction times and costs. This paper describes (1) the process for improving the System 80 standard NSSS design, (2) some of the new features of the System 80+ Standard Design, and (3) the expanded design and licensing scope of the Nuclear Power Module

  18. Explicit TE/TM scheme for particle beam simulations

    International Nuclear Information System (INIS)

    In this paper we propose an explicit two-level conservative scheme based on a TE/TM like splitting of the field components in time. Its dispersion properties are adjusted to accelerator problems. It is simpler and faster than the implicit version. It does not have dispersion in the longitudinal direction and the dispersion properties in the transversal plane are improved. The explicit character of the new scheme allows a uniformly stable conformal method without iterations and the scheme can be parallelized easily. It assures energy and charge conservation. A version of this explicit scheme for rotationally symmetric structures is free from the progressive time step reducing for higher order azimuthal modes as it takes place for Yee's explicit method used in the most popular electrodynamics codes.

    This chapter presents TmPrime, a computer program to design oligonucleotide for both ligase chain reaction (LCR)- and polymerase chain reaction (PCR)-based de novo gene synthesis. The program divides a long input DNA sequence based on user-specified melting temperatures and assembly conditions, and dynamically optimizes the length of oligonucleotides to achieve homologous melting temperatures. The output reports the melting temperatures, oligonucleotide sequences, and potential formation of secondary structures in a PDF file, which will be sent to the user via e-mail. The program also provides functions on sequence pooling to separate long genes into smaller pieces for multipool assembly and codon optimization for expression based on the highest organism-specific codon frequency. This software has been successfully used in the design and synthesis of various genes with total length >20 kbp. This program is freely available at http://prime.ibn.a-star.edu.sg. PMID:22328437

    Riche, Jean-Pierre

    2013-01-01

    Energy efficiency has become a competitive issue for industrial companies. The evolution of energy prices and regulation will make this issue even more important in the future. For several years, the energy-intensive chemical industry has been implementing corrective actions. Helped by the absorption of base load energy consumption by larger production volumes, specific energy consumption (KWh per production unit) has been significantly reduced in recent years. However, most plants have reached the end of their first action plan based on improving the utilities performance. The Leanergy(TM) method developed by the consultancy company Okavango-energy, is a structured approach based on lean manufacturing which widens the scope of saving sources to process and operations. Starting from the analysis of actual production requirements, Okavango is able to adjust consumption to minimum requirements and so remove any energy consumption that does not contribute to the added value creation.

    This study examined the utility of polytomous logistic regression in pixel classification of remotely sensed images by the growth stage of forests. For a population of grouped continuous categories, the assumption of normal distribution of independent variables, which is often required in multivariate classification methods, may not be appropriate. Two types of polytomous logistic regression procedures, multinomial and cumulative logistic regression, were used to classify Landsat TM data by growth stage (regeneration-immature, intermediate, and mature) of loblolly pine (Pinus taeda L.) forest in the east central Mississippi. Multinomial logistic regression is typically used for analysis of unordered categorical data. Cumulative logistic regression is one of the most commonly used methods of ordinal logistic regression which is generally preferred to analyze ordered categorical data, although, it imposes restrictions on the data. Three hundred sample points were located randomly throughout the study site and vectors of pixel values of four bands of Landsat TM data were used to predict growth stage at each sample location. The results were compared to that of parametric and nonparametric discriminant analysis, k-nearest neighbor method. Non-normal distribution of independent variables indicated a violation of the assumptions for parametric discriminant analysis. Classification with cumulative logistic regression using four bands was performed first. However, the assumption of the model was not met. So, the classification was also performed using only band 4 which appeared to meet the assumption. The error rate of cumulative logistic regression was 39.12% with all the bands and 37.70% with band 4 alone. Although error rate with cumulative logistic regression with band 4 alone resulted in the lowest error rate, the improvement over other methods was marginal. The error rate of k-nearest neighbor method varied from 38.68 to 48.06% depending on choice of the value of k.

    Gampe, F.; Raitt, D.

    2002-01-01

    The word "space" has always been associated with and had a profound impact upon architectural design. Until relatively recently, however, the term has been used in a different sense to that understood by the aerospace community - for them, space was less abstract, more concrete and used in the context of space flight and space exploration, rather than, say, an empty area or space requiring to be filled by furniture. However, the two senses of the word space have now converged to some extent. Interior designers and architects have been involved in designing the interior of Skylab, the structure of the International Space Station, and futuristic space hotels. Today, architects are designing, and builders are building, houses, offices and other structures which incorporate a plethora of new technologies, materials and production processes in an effort not only to introduce innovative and adventurous ideas but also in an attempt to address environmental and social issues. Foremost among these new technologies and materials being considered today are those that have been developed for and by the space industry. This paper examines some of these space technologies, such as energy efficient solar cells, durable plastics, air and water filtration techniques, which have been adapted to both provide power while reducing energy consumption, conserve resources and so on. Several of these technologies have now been employed by the European Space Agency to develop a Space House TM - the first of its kind, which will be deployed not so much on planets like Mars, but rather here on Earth. The Space House TM, which exhibits many innovative features such as high strength light-weight carbon composites, active noise-damped, (glass and plastic) windows, low-cost solar arrays and latent heat storage, air and water purification systems will be described.

  4. Validation of IMBA and IMBA expertTM

    International Nuclear Information System (INIS)

    In recent years, ICRP has produced a new set of biokinetic models that are more realistic and scientifically justifiable than their predecessors. In 1997, a collaboration between British Nuclear Fuels (BNFL), Westlakes Research Institute, and the National Radiological Protection Board (NRPB) started with the aim of producing a suite of modules (IMBA: Integrated Modules for Bioassay Analysis) to aid the interpretation of bioassay data. These modules work together to implement the latest ICRP models in order to (a) estimate intakes from bioassay measurements and (b) calculate the resulting internal dose. The modules have since been completed, tested extensively, and are currently in use by the UK Services that are Approved for Internal Dosimetry (ADSs). While the modules themselves are very powerful and flexible, they do require significant knowledge and expertise to implement them correctly. So recent effort has been directed towards the development of user-friendly software, which uses the IMBA modules to obtain the appropriate results. Interest in the IMBA approach has spread beyond the UK. In May 2001, following extensive scientific discussions with internal dosimetrists at many of its nuclear sites, the United States Department of Energy undertook to finance a major implementation of the IMBA modules (IMBA ExpertTM USDOE-Edition). This ambitious project required major extensions to the IMBA modules and the development of a user-friendly interface that controls them. To date, IMBA ExpertTM USDOE-Edition (Phase 1) has been developed with enhanced flexibility and ease of use. Extensive quality assurance tests have been carried out on the software. The aim of this paper is to describe the concepts and capabilities of IMBA and focuses on the quality assurance tests that have been carried out. Monte Carlo simulations have been carried out to test whether the fitting module leads to unbiased estimates of single intakes, and simulated data sets have been used to verify

    2011-06-01

    The paper presents energy transfer in tellurite glass from the system TeO2 - GeO2 - PbO - PbF2- BaO - Nb2O5 - LaF3 doped with Yb3+/Tm3+ ions. Under the excitation of 976 nm laser a strong blue emission (477 nm) corresponding to the transition 1G4 --> 3H6 in thulium ions was observed. Analysing the influence of the content of Tm3+ ions on the level of luminescence obtained by the mechanism of upconversion it was established that the most effective energy transfer between Yb 3+--> Tm3+ ions took place in the matrix doped in the following proportion: 1 Yb3+:0.1 Tm3+ (%mol). Based on the non-resonant process of energy transfer between Yb3+ and Tm3+ ions the mechanism of upconversion was discussed.

    We have made experimental measurements in 170Tm of the following: secondary γ rays, conversion electrons, and γ-γ coincidences from thermal neutron capture in 169Tm, primary γ rays from average resonance capture with 2-keV and 24-keV neutron beams, and proton spectra from the (d,p) reaction on 169Tm. From these data and those of previous investigations, we have identified more than 130 excited levels in 170Tm below 1550 keV. Of these, 62 (with connecting transitions) are placed in 18 rotational bands with assigned Nilsson configurations. These results are in good agreement with a semiempirical modeling of 170Tm level structure. Values for seven Gallagher-Moszkowski splittings and four Newby shifts have been obtained. These matrix elements show remarkably good agreement with calculation. Among the observed Kπ=1- and 2- rotational bands, configuration mixing appears to play a significant role. copyright 1996 The American Physical Society

  7. Scintillation characteristics of Tm3+ in Ca3(BO3)2 crystals

    International Nuclear Information System (INIS)

    Basic optical properties and radiation responses of undoped, Tm3+ 1.0% and 2.0% activated Ca3(BO3)2 (CBO) crystalline scintillator prepared by the micro-pulling down (μ-PD) method are reported. Tm3+: CBO crystals showed three weak absorption bands around 190, 260 and 350 nm, owing to the Tm3+ 4f–4f transition. Strong blue luminescence peaks at 360 and 460 nm which are ascribed to the 1D2–3H6 and 1D2–3F4 transitions of Tm3+ respectively were observed under 241Am 5.5 MeV α-ray excitation. The scintillation light yield of 2.0% Tm3+-doped CBO crystal was evaluated to be about 250 ph/n from the 252Cf excited pulse height spectrum.

    A prototype of the Rf Focused Interdigital (RFI) linac structure is currently under construction at Linac Systems. The RFI linac structure is basically an interdigital (or Wideröe) linac structure with rf quadrupole focusing incorporated into each drift tube. The 200 MHz RFI prototype, consisting of a short RFQ linac followed by a short RFI linac, will accelerate a 20 mA beam of protons from an injection energy of 25 keV to an output energy of 2.50 MeV in a total linac structure length of 1.44 meters. The linac structures are designed for continuous (cw) operation, and will be tested initially at a 33% duty factor. The peak structure power of 66 kW and peak beam power of 50 kW will be supplied by a 144 kW, 33% duty rf power system. A microwave ion source will supply the proton beam and an articulated Einzel lens will steer and focus the beam into the RFQ aperture. The mechanical design of the linac structures will be presented, the calculated performance will be described, the status of the components will b...

    1998-09-01

    Shear sensing ability it important in many fields such as robotics, rehabilitation, teleoperation and human computer interfaces. A shear sensitive tactile sensor prototype is developed based on the principles of the piezoresistive effect in silicon, and using microfabrication technology. Analogous to the conventional silicon piezoresistive pressure sensor, piezoresistive resistors embedded in a silicon diaphragm are used to sense stress change. An additional mesa is fabricated on the top of the diaphragm and serves to transform an applied force to a stress. Both the shear and normal components of the force are resolved by measuring the resistance changes of the four resistors placed at the corners of a prism mesa. The prototype is tested both statically and dynamically when a spatial force of 0 - 300 gram is applied. Good linearity (R > 0.98) and high repeatability are observed. In this paper, the force sensing mechanism and force determination approach are described. The fabrication process is presented. The preliminary testing results are presented and discussed.

  10. Prototyping Advanced Control Systems on FPGA

    2009-01-01

    Full Text Available In advanced digital control and mechatronics, FPGA-based systems on a chip (SoCs promise to supplant older technologies, such as microcontrollers and DSPs. However, the tackling of FPGA technology by control specialists is complicated by the need for skilled hardware/software partitioning and design in order to match the performance requirements of more and more complex algorithms while minimizing cost. Currently, without adequate software support to provide a straightforward design flow, the amount of time and efforts required is prohibitive. In this paper, we discuss our choice, adaptation, and use of a rapid prototyping platform and design flow suitable for the design of on-chip motion controllers and other SoCs with a need for analog interfacing. The platform consists of a customized FPGA design for the Amirix AP1000 PCI FPGA board coupled with a multichannel analog I/O daughter card. The design flow uses Xilinx System Generator in Matlab/Simulink for system design and test, and Xilinx Platform Studio for SoC integration. This approach has been applied to the analysis, design, and hardware implementation of a vector controller for 3-phase AC induction motors. It also has contributed to the development of CMC's MEMS prototyping platform, now used by several Canadian laboratories.

  11. Prototyping the CBM Micro Vertex Detector

    International Nuclear Information System (INIS)

    For the reconstruction of Open Charm Hadrons with the CBM experiment a Micro Vertex Detector (MVD) with an excellent resolution of the secondary decay vertex (< 70 μm along the beam axis) is required. To achieve this vertex resolution a material budget of a few 0.1% X0 is mandatory for the individual detector stations positioned downstream in close vicinity to the target. To further reduce the multiple scattering the MVD operates in vacuum. The need of prototyping and characterizing the CBM-MVD motivated the construction of an advanced device - a beam telescope - giving the opportunity to exercise the following aspects: handling and integration of ultra-thin CMOS sensors on advanced materials like CVD diamond, double sided sensor assembly for ultra-precise tracking, cooling, scalable readout and slow control, development of data analysis framework and first steps towards implementation of tracking algorithms into a FPGA-based hardware. This group report aims to summarize the activity towards fabrication of the CBM-MVD prototype.

    The Advanced Space Suit team of the NASA-Johnson Space Center performed a series of test with the Z-1 prototype space suit in 2012. This paper discusses, at a summary level, the tests performed and results from those tests. The purpose of the tests were two-fold: 1) characterize the suit performance so that the data could be used in the downselection of components for the Z-2 Space Suit and 2) develop interfaces with the suitport and exploration vehicles through pressurized suit evaluations. Tests performed included isolated and functional range of motion data capture, Z-1 waist and hip testing, joint torque testing, CO2 washout testing, fit checks and subject familiarizations, an exploration vehicle aft deck and suitport controls interface evaluation, delta pressure suitport tests including pressurized suit don and doff, and gross mobility and suitport ingress and egress demonstrations in reduced gravity. Lessons learned specific to the Z-1 prototype and to suit testing techniques will be presented.

  13. A prototype silicon preradiator for the SSC

    International Nuclear Information System (INIS)

    The authors describe the design and first results from the test of a prototype of a preradiator detector. Such a detector could be used to enhance the identification of photons and electrons at the Superconducting Super Collider (SSC). Specifically, it may be used by the GEM detector to distinguish between single photons from Higgs decay and background photon pairs from π0 decay. The prototype consists of tungsten radiator followed by silicon strip detectors. The tungsten thickness was changeable, varying from 0 to 3 radiation lengths. Two silicon detectors, oriented in X and Y, consist of 48 strips, each of length 48 mm. The pitch is 1mm. This granularity is required for separating single and multi-photons at the SSC. The readout is achieved by low-noise, low-power custom preamplifier chips mounted directly on the detectors via custom circuit boards. This preradiator was tested in a beam at Brookhaven (BNL) in July 1992. A lead glass array placed behind the silicon was used to determine energy resolution effects. The results from the test on spatial distributions and energy resolution, including correction for the energy deposited in the preradiator are presented, along with comparisons to EGS simulations

    A report was published by the Idaho National Laboratory in September of 2012, entitled Design to Achieve Fault Tolerance and Resilience, which described the benefits of automating operator actions for transients. The report identified situations in which providing additional automation in lieu of operator actions would be advantageous. It recognized that managing certain plant upsets is sometimes limited by the operator’s ability to quickly diagnose the fault and to take the needed actions in the time available. Undoubtedly, technology is underutilized in the nuclear power industry for operator assistance during plant faults and operating transients. In contrast, other industry sectors have amply demonstrated that various forms of operator advisory systems can enhance operator performance while maintaining the role and responsibility of the operator as the independent and ultimate decision-maker. A computerized operator support system (COSS) is proposed for use in nuclear power plants to assist control room operators in addressing time-critical plant upsets. A COSS is a collection of technologies to assist operators in monitoring overall plant performance and making timely, informed decisions on appropriate control actions for the projected plant condition. The COSS does not supplant the role of the operator, but rather provides rapid assessments, computations, and recommendations to reduce workload and augment operator judgment and decision-making during fast-moving, complex events. This project proposes a general model for a control room COSS that addresses a sequence of general tasks required to manage any plant upset: detection, validation, diagnosis, recommendation, monitoring, and recovery. The model serves as a framework for assembling a set of technologies that can be interrelated to assist with each of these tasks. A prototype COSS has been developed in order to demonstrate the concept and provide a test bed for further research. The prototype is based

  16. Results on the LHCb hadron calorimeter prototype

    International Nuclear Information System (INIS)

    The hadron calorimeter HCAL of the LHCb experiment at CERN is the key device which provides data for the level-0 high pt trigger and can perform fast trigger signal construction with reasonable background suppression when B decays are reconstructed. During 1997-1999 an HCAL prototype stack of 6 modules of 0.96 x 0.96 m2 front surface and with different internal structure has been constructed and exposed to the X7 test beams of the SPS at CERN. HCAL technology consists of a scintillator/iron sampling structure with scintillating tiles parallel to the beam axis and a passive radiator made of steel plates. The absorber plates were supplied by Romanian, CERN and IPT Kharkiv groups. Scintillating tiles have been produced in Russia using a modern casting technique. In the prototype we use Pol.Hi.Tech.(S250) single clad wave-length shifting fibers of 1 mm in diameter with a polished and aluminized mirror at one end. Parts of two HCAL modules have been recently re-assembled with new faster fiber of type Bicron BCF-92 and irradiated components. Two types of Russian photomultipliers have been used in the CAL Prototype beam-tests: FEU-84-3 and FEU-115M. A calibration system with radioactive source and pulsing LED has been used and checked. Beam tests with the HCAL Prototype have been done at the X7 beam-line of the West Area experimental hall at CERN in a wide beam momentum range from 5 to 100 GeV. A rotating table on the platform allows to turn the detector on up to 180 angle around he vertical axis and a lateral and an up-down displacement of 2 m. A computer controlled High Voltage distribution scheme, developed by IFIN-HH group, allows individual setting of the HV on each PMT for the gain adjustment with a minimal amount of cables. The system consists of three parts: 1) the control box which includes the low voltage power supply, the RS232 interface to a PC and three modules of the high voltage power supply: two with Vmax = 2000 V, Imax = 10 mA and one with Vmax = 2500 V

  17. Transmission electron microscopy study of the MgS–Tm2S3 system

    International Nuclear Information System (INIS)

    This work presents the structural–microstructural characterization of the NaCl-derivative MgS–Tm2S3 system, which can be formulated by the expression Mg(1−x)Tm(2/3)x□(1/3)xS (□→cation vacancy). Transmission electron microscopy observations show the transition between NaCl-type and spinel-type structures when 0 ≤x≤ 0.75. The increase of Tm content in the solid solution provokes the increase of the spinel-type phase proportion, which intergrows with the NaCl-type crystals. When x≥0.75, some phases derived from NaCl-type structure through the chemical twinning at the unit cell level crystallographic operation are observed, such as CT-MgTm2S4 and CT-MgTm4S7. The existence and nature of the extended defects observed along the c direction of these structures are characterized by means of Scanning-Transmission electron microscopy high-angle dark field imaging, which allows observing the presence of quasi ordered crystals with new possible complex stoichiometries at atomic resolution. - Graphical abstract: HAADF-STEM image of a disordered CT-MgYb2S4 crystal. The disordered twin-slab sequences are marked by arrows. - Highlights: • Structural evolution of the Mg(1−x)Tm(2/3)x□(1/3)xS system was characterized by means of TEM. • The increase in Tm content provokes the transition from NaCl to spinel-type structure up to x=0.75. • Chemical twinned phases CT-MgTm2S4 and CT-MgTm4S7 are observed at high Tm contents. • Extended defects in CT-crystals are characterized with atomic resolution STEM-HAADF images

    A superconducting radio frequency (SRF) cavity with a geometrical beta of 0.42 has been designed to accelerate a proton beam after 100 MeV for an extension of Proton Engineering Frontier Project (PEFP). The designed cavity shape is an elliptical and the resonant frequency is 700 MHz. In order to confirm the RF and mechanical properties of the cavity, two prototypes of copper cavities have been fabricated and tested. Based on the experiences gained with the copper prototypes, two niobium prototypes have been designed. One is two-cell cavity and the other is five cell cavity. The two-cell cavity is for finalizing the niobium cavity production procedure and testing the cavity RF properties at a low temperature and moderate power level. The five-cell cavity is for checking the production quality and testing vertical test system in the future. Both of them are under fabrication. Through the fabrication of the niobium prototype, several issues such as deep drawing, electron beam welding and surface treatment will be addressed. The drawing of the PEPF SRF low beta cavity is shown in Fig. 1. Major parameters for the cavity are like following. - Frequency: 700 MHz - Operating mode: TM010 pi mode - Cavity type: Elliptical - Geometrical beta: 0.42 - Number of cells: 5 per cavity - Accelerating gradient: 8 MV/m - Epeak/Eacc: 3.71 - Bpeak/Eacc: 7.47 mT/(MV/m) - R/Q: 102.3 ohm - Epeak: 29.68 MV/m - Field flatness: 1.56 % - Cell to cell coupling: 1.41 % - Geometrical factor: 121.68 ohm - Cavity wall thickness: 4.3 mm - Lorentz force detuning: 0.4 Hz/(MV/m)2 - Stiffening structure: Double ring - Effective length: 0.45 m - External Q of FPC: 8.0E5 {+-}20 % - HOM load: less than 2 W - HOM Qext requirement: less than 3.0E5 At present, all the niobium disk and plates for cavity and NbTi flanges for beam pipe flange are prepared.

  2. Results of the prototype camera for FACT

    International Nuclear Information System (INIS)

    The maximization of the photon detection efficiency (PDE) is a key issue in the development of cameras for Imaging Atmospheric Cherenkov Telescopes. Geiger-mode Avalanche Photodiodes (G-APD) are a promising candidate to replace the commonly used photomultiplier tubes by offering a larger PDE and in addition a facilitated handling. The FACT (First G-APD Cherenkov Telescope) project evaluates the feasibility of this change by building a camera based on 1440 G-APDs for an existing small telescope. As a first step towards a full camera, a prototype module using 144 G-APDs was successfully built and tested. The strong temperature dependence of G-APDs is compensated using a feedback system, which allows to keep the gain of the G-APDs constant to 0.5%.

  3. Results of the CALICE SDHCAL technological prototype

    International Nuclear Information System (INIS)

    The SDHCAL prototype was completed in 2012, and exposed to beams of pions, electrons of different energies at the SPS of CERN for a total time period of 5 weeks. The data are being analyzed within the CALICE Collaboration. Preliminary results indicate that a highly granular hadronic calorimeter conceived for PFA application is also a powerful tool to measure hadronic particle energy. In addition it was found to discriminate efficiently pions from electrons. The use of multi-threshold readout mode shows a clear improvement of the resolution at energies exceeding 30 GeV with respect to the binary readout mode. New ideas to improve on the energy resolution using the topology of hadronic showers such as the Hough Transform technique are studied

    The SDHCAL technological prototype that has been completed in 2012 was exposed to beams of pions and electrons of different energies at the CERN SPS for a total time period of 5 weeks. The data has been analyzed within the CALICE collaboration. Preliminary results indicate that a highly granular hadronic calorimeter conceived for PFA application is also a powerful tool to separate pions from electrons. The SDHCAL provides also a very good resolution of hadronic showers energy measurement. The use of multi-threshold readout mode shows a clear improvement of the resolution at energies exceeding 30 GeV with respect to the binary readout mode. Simulations of the pion interactions in the SDHCAL are presented and new ideas to improve on the energy resolution using the topology of hadronic showers are mentioned.

    The ELENA bending magnet prototype shall prove that the proposed design meets the requirements set by the ELENA beam dynamics. The following points will be discussed in detail: (i) production process of a magnetic yoke diluted with stainless steel plates, (ii) the stability and repeatability of the field homogeneity of such a yoke over the full working range, (iii) choice of soft magnetic steel, (iv) hysteresis effects, (v) mechanical deformations, (vi) thermal insulation to intercept heat load from baking for activation of NEG coating in the vacuum chamber, (vii) end shim design. In order to verify these points the following measurements will be performed: (i) Hall probe scanning, (ii) integrated field homogeneity measurement (DC), (iii) integrated field homogeneity measurement (AC).

  6. Data-sharing protocol: A prototype implementation

    International Nuclear Information System (INIS)

    This paper describes a client/server communication protocol which will allow physicists to access data from cooperating remote experiments. Special low-level ''client'' software within the user's ''home'' data-access library formulates a request for data from the remote experiment. This request is sent over a network to a server at the remote site. The server has specific knowledge about the location and format of the requested data. The server gets the data and sends it over the network to the requesting client, which reformats the data according to the local library's conventions. Our prototype is being developed to suppose remote access to data from ATF, PBX, and micro Vax data from Tore-Supra. We have attempted to create a flexible design which should accommodate data from other experiments as well

  7. EOS distributed planning and scheduling prototype

    Science.gov (United States)

    Hull, Larry G.; Peters, Stephen F.; Davis, Randy

    Some of the more significant lessons learned during the development of the Earth Observing System (EOS) Distributed Planning and Scheduling Prototype are presented. The need for a central scheduler is not demonstrated. A mapping of scheduling and conflict-resolution responsibility across the nodes of the EOS distributed scheduling system is developed and shown to be both feasible and appropriate. Complex instrument scheduling is mostly accomplished at the ICC/IST (instrument control center/instrumental support terminal) with 'slidable' flexibility for slews and some kinds of calibrations resolved at the EOS Operations Center (EOC). All nodes have full visibility interinstrument contention for resource and environmental rights, e.g., vibration, thermal, and electromagnetic. The EOC assigns, by activity, initial action responsibility for conflict resolution to a node which is party to the conflict. Most interinstrument conflicts are resolved by the ICCs and ISTs during an intermediate scheduling phase while the EOC is negotiating a TDRS schedule with the NCC.

  8. Prototype rf cavity for the HISTRAP accelerator

    International Nuclear Information System (INIS)

    HISTRAP, a proposed synchrotron-cooling-storage ring designed to both accelerate and decelerate very highly charged very heavy ions for atomic physics research, requires an rf accelerating system to provide /+-/2.5 kV of peak accelerating voltage per turn while tuning through a 13.5:1 frequency range in a fraction of a second. A prototype half-wave, single gap rf cavity with biased ferrite tuning was built and tested over a continuous tuning range of 200 kHz through 2.7 MHz. Initial test results establish the feasibility of using ferrite tuning at the required rf power levels. The resonant system is located entirely outside of the accelerator's 15cm ID beam line vacuum enclosure except for a single rf window which serves as an accelerating gap. Physical separation of the cavity and the beam line permits in situ vacuum baking of the beam line at 300/degree/C

    The quality of PMT signal is one of the key items for a large and high precision neutrino experiment, like Daya Bay, JUNO, while most of the experiments are affected by the PMT signal overshoot from its positive HV-single cable scheme. For JUNO prototype detector, we have a detailed study on the PMT overshoot and successfully reduced the ratio of overshoot amplitude to signal to ~1% from previous typical ~10%, with no affection to PMT other parameters. Furthermore, we calculated that the overshoot is a result of discharging of capacitors in the HV-signal splitter and the PMT voltage divider. The study result is extremely important for JUNO and other similar experiments.

  10. Safeguards in Prototype Fast Breeder Reactor Monju

    International Nuclear Information System (INIS)

    The assemblies loaded in the core and stored in the ex-vessel storage tank (EVST) are in liquid sodium in the Japanese prototype fast breeder reactor (FBR) Monju. Since it is difficult to apply a direct verification procedure for the fuel assemblies in these areas, a dual containment and surveillance system consisting of two monitoring devices such as surveillance camera and radiation monitor that are functionally independent has been applied. In addition, the Monju Remote Monitoring System was developed to strengthen the continuous surveillance and to reduce the load of the inspection activities. Furthermore, the ex-vessel transfer machine radiation monitor (EVRM) and the exit gate monitor (EXGM) were upgraded to strengthen the monitoring of spent blanket fuel assemblies and to improve the reliability of distinguishing between fuel assemblies and non-fuel items. As the result, the integrated safeguards was introduced in November 2009, and the effective safeguards activities have been implemented in Monju. (author)

    Materials used in ossicular replacement prostheses must demonstrate appropriate biological compatibility, acoustic transmission, stability, and stiffness properties. Prostheses prepared using Teflon ®, titanium, Ceravital and other conventional materials have demonstrated several problems, including migration, perforation of the tympanic membrane, difficulty in shaping the prostheses, and reactivity with the surrounding tissues. We have used two-photon polymerization for rapid prototyping of Ormocer ® middle-ear bone replacement prostheses. Ormocer ® surfaces fabricated using two-photon polymerization exhibited acceptable cell viability and cell growth profiles. The Ormocer ® prosthesis was able to be inserted and removed from the site of use in the frozen human head without fracture. Our results demonstrate that two-photon polymerization is able to create ossicular replacement prostheses and other medical devices with a larger range of sizes, shapes and materials than other microfabrication techniques.

    We have been developing a Cherenkov ring-imaging counter, named TOP counter, as a particle-identification device of the Belle-II detector for the super B-factory at KEK. In this presentation, we show the R&D status of the TOP counter prototype. We performed a beam test using 2 m long quartz radiator and MCP-PMTs, and evaluated the number of detected photons, time resolution and chromatic effects. We developed a square-shape MCP-PMT with Hamamatsu photonics, so as to obtain a sufficient lifetime under the Belle-II environment. We improved the lifetime of the quantum efficiency by changing the internal structure and production process, and then obtained a lifetime of >350 mC/cm2.

    Bader, Brett William; Kolda, Tamara Gibson (Sandia National Laboratories, Livermore, CA)

    2004-10-01

    Tensors (also known as mutidimensional arrays or N-way arrays) are used in a variety of applications ranging from chemometrics to psychometrics. We describe four MATLAB classes for tensor manipulations that can be used for fast algorithm prototyping. The tensor class extends the functionality of MATLAB's multidimensional arrays by supporting additional operations such as tensor multiplication. The tensor as matrix class supports the 'matricization' of a tensor, i.e., the conversion of a tensor to a matrix (and vice versa), a commonly used operation in many algorithms. Two additional classes represent tensors stored in decomposed formats: cp tensor and tucker tensor. We descibe all of these classes and then demonstrate their use by showing how to implement several tensor algorithms that have appeared in the literature.

  14. The prototype GAPS (pGAPS) experiment

    International Nuclear Information System (INIS)

    The General Antiparticle Spectrometer (GAPS) experiment is a novel approach for the detection of cosmic ray antiparticles. A prototype GAPS (pGAPS) experiment was successfully flown on a high-altitude balloon in June of 2012. The goals of the pGAPS experiment were: to test the operation of lithium drifted silicon (Si(Li)) detectors at balloon altitudes, to validate the thermal model and cooling concept needed for engineering of a full-size GAPS instrument, and to characterize cosmic ray and X-ray backgrounds. The instrument was launched from the Japan Aerospace Exploration Agency's (JAXA) Taiki Aerospace Research Field in Hokkaido, Japan. The flight lasted a total of 6 h, with over 3 h at float altitude (∼33km). Over one million cosmic ray triggers were recorded and all flight goals were met or exceeded

  15. SuperB Muon Detector Prototype

    International Nuclear Information System (INIS)

    The test objective is to optimize the muon identification in an experiment at a Super B Factory. To accomplish this, experimenters will study the muon identification capability of a detector with different iron configurations at different beam energies. The detector is a full scale prototype, composed of a stack of iron tiles. The segmentation of the iron allows the study of different configurations. Between the tiles, one or two extruded scintillator slabs can be inserted to test two different readout options; a Binary Readout and a Time Readout. In the Binary Readout option the two coordinates are given by the two orthogonal scintillator bars, and the spatial resolution is driven by the bar width. In the Time Readout option one coordinate is determined by the scintillator position and the other by the arrival time of the signal read with a TDC.

    The design, development, and evaluation of a prototype modular lens assembly with a self-contained field sequential color wheel is presented. The design of a color wheel of maximum efficiency, the selection of spectral filters, and the design of a quiet, efficient wheel drive system are included. Design tradeoffs considered for each aspect of the modular assembly are discussed. Emphasis is placed on achieving a design which can be attached directly to an unmodified camera, thus permitting use of the assembly in evaluating various candidate camera and sensor designs. A technique is described which permits maintaining high optical efficiency with an unmodified camera. A motor synchronization system is developed which requires only the vertical synchronization signal as a reference frequency input. Equations and tradeoff curves are developed to permit optimizing the filter wheel aperture shapes for a variety of different design conditions.

    The MIT Light Eagle human-powered aircraft underwent long-duration testing over Rogers Dry Lake in California during January, 1987. Designed as a prototype for the MIT Daedalus Project, the Light Eagle's forty-eight flights provided pilot training, established new distance records for human-powered flight, and provided quantitative data through a series of instrumented flight experiments. The experiments focused on: (1) evaluating physiological loads on the pilot, (2) determining airframe power requirements, and (3) developing an electronic flight control system. This paper discusses the flight test program, its results and their implications for the follow-on Daedalus aircraft, and the potential uses of the Light Eagle as a low Reynolds number testbed.

  18. The SSC full cell prototype string test

    International Nuclear Information System (INIS)

    At the conclusion of the SSC half cell magnet string testing program. In February, 1993, the preliminary data analysis revealed that several substantive technical questions remained unresolved. These questions were: (1) could the high voltages to ground (>2 kV) measured during fault (quench) conditions be substantially reduced, (2) could the number of magnetic elements that became resistive (quenched) be controlled and (3) did the cryostats of the magnetic elements provide adequate insulation and isolation to meet designed refrigeration loads. To address these and other existing question a prototypical full cell of collider magnets (ten dipoles and two quadrupoles) was assembled and tested. At the conclusion of this testing there were definitive answers to most of the questions with numerical substantiation, the notable exception being the beat leak question. These answers and other results and issues are presented in this paper

    International Nuclear Information System (INIS)

    The prototype of target to produce Mo-99 by fission has been manufactured. Extension equipment using oil pressure is specially designed and fabricated in order to prepare the Mo-99 target of high quality to be irradiated in a research reactor. The target of an annular type of inner and outer Al tubes and uranium foil in between is extended using a dedicated tool with a draw plug. The inner tube is plastically deformed while the outer tube is elastically deformed. This makes the Al tubes and foil contacted closely. Top and bottom ends of the target are welded by TIG in order to provide a hermetic sealing which will prevent the release of fission gases during the irradiation

    NASA's Z-2 prototype space suit is the highest fidelity pressure garment from both hardware and systems design perspectives since the Space Shuttle Extravehicular Mobility Unit (EMU) was developed in the late 1970's. Upon completion the Z-2 will be tested in the 11 foot human-rated vacuum chamber and the Neutral Buoyancy Laboratory (NBL) at the NASA Johnson Space Center to assess the design and to determine applicability of the configuration to micro-, low- (asteroid), and planetary- (surface) gravity missions. This paper discusses the 'firsts' that the Z-2 represents. For example, the Z-2 sizes to the smallest suit scye bearing plane distance for at least the last 25 years and is being designed with the most intensive use of human models with the suit model.

    The design, manufacturing, and performance characterization of a MEMS-scale turbine prototype is reported. The turbine is designed for integration into a respiration harvester that can convert normal human breathing into electrical power through electromagnetic induction. The device measures 10 mm in radius, and employs 12 blades located around the turbine periphery along with ball bearings around the center. Finite element simulations showed that an average torque of 3.07 μNm is induced at 12 lpm airflow rate, which lies in normal breathing levels. The turbine and a test package were manufactured using CNC milling on PMMA. Tests were performed at respiration flow rates between 5-25 lpm. The highest rotational speed was measured to be 9.84 krpm at 25 lpm, resulting in 8.96 mbar pressure drop across the device and 370 mW actuation power.

    A Micromegas [1] detector with four active layers, serving as prototype for the upgrade of the ATLAS muon spectrometer [2], was designed and constructed in 2014 at CERN and represents the first example of a Micromegas quadruplet ever built. The detector has been realized using the resistive-strip technology and decoupling the amplification mesh from the readout structure. The four readout layers host overall 4096 strips with a pitch of 415 μm; two layers have strips running parallel (η in the ATLAS reference system, for measuring the muon bending coordinate) and two layers have inclined strips by ±1.5° angle with respect to the η coordinate in order to provide measurement of the second coordinate. A detector characterization carried out with cosmic muons and under X-ray irradiation is presented with the obtained results.

    The effects of Tm substitution on the dynamical magnetic response of Yb1-xTmxB12 (x=0, 0.08, 0.15, and 0.75) and Lu0.92Tm0.08B12 compounds have been studied using time-of-flight inelastic neutron scattering. Major changes were observed in the spectral structure and temperature evolution of the Yb contribution to the inelastic response for a rather low content of magnetic Tm ions. A sizable influence of the RB12 host (YbB12, as compared to LuB12 or pure TmB12) on the crystal-field splitting of the Tm3+ ion is also reported. The results point to a specific effect of impurities carrying a magnetic moment (Tm, as compared to Lu or Zr) in a Kondo insulator, which is thought to reflect the "undercompensation" of Yb magnetic moments, originally Kondo screened in pure YbB12. A parallel is made with the strong effect of Tm substitution on the temperature dependence of the Seebeck coefficient in Yb1-xTmxB12, which was reported previously.

  8. Anomalous dispersion properties of TM waves in subwavelength metallic waveguides loaded by uniaxial metamaterials

    International Nuclear Information System (INIS)

    Dispersion properties of transverse magnetic (TM) waves in a subwavelength metallic waveguide loaded by uniaxial metamaterials are investigated, based on two kinds of uniaxial metamaterials with different orientations of optical axis. The numerical results show that the existence of fundamental TM0 mode and high-order TM modes in the waveguide system is dependent on the orientation of optical axis. In addition, their anomalous dispersion properties are clarified. When the orientation of optical axis is selected properly, there are two branches of dispersion curves for each high-order mode—one is normal dispersion and another belongs to anomalous dispersion, showing a transition from a backward wave to a forward one with the increase of working frequency. Moreover, the group velocity and energy flow distribution for TM1 mode are also demonstrated. These properties may have potential applications in optical information storage, integrated optics and nanophotonic devices. - Highlights: • Two kinds of subwavelength uniaxial metamaterial waveguides are constructed. • We demonstrate anomalous dispersion properties of transverse magnetic (TM) guided modes. • There are two branches of dispersion curves for high-order TM modes, showing a transition from a backward wave to a forward one. • Group velocity can approach to zero, having potential application in optical information storage. • Negative group velocity and energy flow distribution for TM modes are shown

  9. A Rapid Prototyping Environment for Wireless Communication Embedded Systems

    2003-05-01

    Full Text Available This paper introduces a rapid prototyping methodology which overcomes important barriers in the design and implementation of digital signal processing (DSP algorithms and systems on embedded hardware platforms, such as cellular phones. This paper describes rapid prototyping in terms of a simulation/prototype bridge and in terms of appropriate language design. The simulation/prototype bridge combines the strengths of simulation and of prototyping, allowing the designer to develop and evaluate next-generation communications systems, partly in simulation on a host computer and partly as a prototype on embedded hardware. Appropriate language design allows designers to express a communications system as a block diagram, in which each block represents an algorithm specified by a set of equations. Software tools developed for this paper implement both concepts, and have been successfully used in the development of a next-generation code division multiple access (CDMA cellular wireless communications system.

  11. Using Landsat TM data to model corn and soybean yields

    Candanedo Guevara, Martin Edmundo

    2001-07-01

    Early research in agriculture used remotely sensed data mostly for the identification of spectral signatures, where crop type/area classification would depend on data acquired from hand-held or truck-mounted instruments. Through time different approaches were taken for crop type/area classification, such as a systematic sampling of inventory ground data that were used later for training and testing using image processing techniques. Later, technology such as the global positioning system (GPS) and geographic information systems (GIS) were used for application to precision agriculture. These new tools provided a better meaning to understand and analyze the complex variability of the crop-soil-atmosphere system to estimate crop yields. The present research used data collected in the Management System Evaluation Area (MSEA) in 1998 and two Landsat thematic Mapper images (July and August) to analyze the crop variability. Ground truth parameters, such as chlorophyll, leaf area index (LAI), and electricity conductivity, were collected throughout the growing season. In addition, vegetation indexes (VI) such as the Normalized difference vegetation index (NDVI), simple vegetation index (SVI), soil adjusted ratio vegetation index (SARVI), were computed for the two images. Both ground truth data and VI's were statistically analyzed with yield measurements taken with an on-the-go yield monitor to estimate a best fit yield model for use with soybeans and corn. The correlation analysis within a Landsat pixel reported SVI52 (r = 0.62), SVI53 (r = 0.56), and SVI54 (r = 0.53) as the most significant relationships. The results from the ground truth data vs. on-the-go yields reported total clay (%) (r = 0.90), leaf area (r = 0.76), and tissue plant analysis (r = 0.73) A stepwise regression analysis was performed using the Landsat TM images and the VI's selected. A series of linear models were evaluated taking into account the Landsat TM and yield while varying the scale (1 pixel to

    The main objective of this research is to determine the capacity of land cover classification combining spectral and textural features of Landsat TM imagery with ancillary geographical data in wetlands of the Sanjiang Plain, Heilongjiang Province, China. Semi-variograms and Z-test value were calculated to assess the separability of grey-level co-occurrence texture measures to maximize the difference between land cover types. The degree of spatial autocorrelation showed that window sizes of 3×3 pixels and 11×11 pixels were most appropriate for Landsat TM image texture calculations. The texture analysis showed that co-occurrence entropy, dissimilarity, and variance texture measures, derived from the Landsat TM spectrum bands and vegetation indices provided the most significant statistical differentiation between land cover types. Subsequently, a Classification and Regression Tree (CART) algorithm was applied to three different combinations of predictors: 1) TM imagery alone (TM-only); 2) TM imagery plus image texture (TM+TXT model); and 3) all predictors including TM imagery, image texture and additional ancillary GIS information (TM+TXT+GIS model). Compared with traditional Maximum Likelihood Classification (MLC) supervised classification, three classification trees predictive models reduced the overall error rate significantly. Image texture measures and ancillary geographical variables depressed the speckle noise effectively and reduced classification error rate of marsh obviously. For classification trees model making use of all available predictors, omission error rate was 12.90% and commission error rate was 10.99% for marsh. The developed method is portable, relatively easy to implement and should be applicable in other settings and over larger extents.

  13. Fabrication and properties of Er/Tm/Pr tri-doped yttrium lanthanum oxide transparent ceramics

    International Nuclear Information System (INIS)

    Highlights: • Er/Tm/Pr:(Y0.9La0.1)2O3 transparent ceramics were fabricated by conventional ceramics processing. • The sensitization of 2.7 μm emitted light of Er3+ ion is realized by co-doping Tm3+ and Pr3+ ions into Er3+-doped transparent ceramic. • The mechanism of the 2.7 μm emissions of Pr/Er/Tm:(Y0.9La0.1)2O3 ceramics is explained by the energy sketch. • Er/Tm/Pr:(Y0.9La0.1)2O3 ceramics exhibit the potential as a good candidate for mid-infrared lasers. - Abstract: Er/Tm/Pr tri-doped yttrium lanthanum oxide transparent ceramics were fabricated by conventional ceramics processing. Their microstructures and spectroscopic properties were investigated. The energy transfer mechanism between Tm3+, Pr3+ and Er3+ was also discussed. The Er/Tm/Pr:(Y0.9La0.1)2O3 ceramics display a dense structure with no pores and uniform grains of about 40 μm. The results shows that population inversion between the 4I11/2 and 4I13/2 level of Er:(Y0.9La0.1)2O3 transparent ceramics is enhanced by co-doping Tm3+ and low amount of Pr3+ (0.5 at.%). When concentration of Pr3+ ions is high (2 at.%), 2.7 μm emission is restrained significantly due to the concentration quenching of Pr3+ ions. This Er/Tm/Pr tri-doped yttrium lanthanum oxide transparent ceramics can be considered as a promising material for mid-infrared lasers

  20. Point contact spectroscopy of SmB6, TmSe, ''gold'' SmS and TmSesub(1-x)Tesub(x): gaps

    International Nuclear Information System (INIS)

    The dynamic resistance dU/dI(U) and its derivative d2U/dI2(U) were measured of point contacts with intermediate valent SmB6, ''gold''SmS, TmSe and ferromagnetic TmSesub(0.82)Tesub(0.18) and their integer valent reference compounds LaB6, LaS, LaSe and Tmsub(0.87)Se at liquid helium temperatures. While dU/dI(U) of point contacts with the integer valent compounds does not show any anomalous structures, SmB6, ''gold''SmS and TmSe (in the antiferromagnetic phase) exhibit a strong resistance peak at zero bias with a characteristic width of 5 meV, 6.5 meV and 2.5 meV, respectively. This is taken as evidence of hybridization gaps. Point contacts with ferromagnetic TmSesub(0.82)Tesub(0.18) show below Tsub(c) a shape of dU/dI(U) which is similar to that of TmSe in its field induced ferromagnetic phase. (Auth.)

  1. The effect of Mg2+ ions in Er3+,Tm3+-codoped LiNbO3 single crystal

    International Nuclear Information System (INIS)

    Absorption, photoluminescence (PL), and PL excitation (PLE) spectra are studied for LiNbO3 (LNO) single crystal doped with Er (0.2 wt%), Tm (0.3 wt%), and Mg (2.6 wt%), LNO crystal doped with Er (0.3 wt%), and LNO crystal doped with Tm (0.2 wt%). The same absorption and PL bands due to Er3+ and Tm3+ as observed in the singly doped LNOs are observed in the Mg-codoped LNO. Additional PL and absorption bands are not observed in the Mg-codoped LNO, indicating that the energy states of Er and Tm are not changed by Mg even if Mg ions are located close to Er and Tm ions. It is found that the wavelengths of the PL band peaks due to Tm (also Er) are not changed in the Mg-codoped LNO but the intensity ratio among the Tm (Er) emission components is changed. These results are understood by the energy transfer between Tm and Er or by the Mg doping effect. It is concluded that Mg does not influence the electronic states of Er and Tm in LNO, but it influences the emission spectra of Er and Tm. - Highlights: • Er, Tm and Mg LiNbO3 crystals are compared to single doped in terms of spectroscopy. • States of Er and Tm are not changed by Mg even if Mg ions are located close to Er and Tm. • Tm ions (also Er ions) occupy both Li and Nb sites in LiNbO3 even if Mg is not doped. • When Mg ions are doped, some of Tm (Er) at Li move to Nb sites because Mg ions occupy Li sites

    Tm3+/Yb3+ codoped transparent glass ceramic containing β-PbF2 nanocrystals was successfully prepared. After thermal treatment, emissions from the state of Tm3+ excited by 980 nm laser were greatly quenched by cross relaxation and the 700 nm luminescence from Tm3+:3F2,3→3H6 transition was strongly enhanced. A nearly monochromatic red luminescence band was observed. Based on the luminescence decay curves and Judd-Ofelt analysis, the strengthened cross relaxation played an important role in such phenomenon. PMID:22854468

    The lanthanide complex, thulium 1,4,7,10-tetraazacyclodo- decane-1,4,7,10-tetraacetic acid (TmDOTA-), has been investigated as an agent for MR thermometry in vivo. The chemical shifts of the TmDOTA- protons were highly sensitive to temperature at a clinically relevant field strength, yet insensitive to pH and the presence of Ca2+. Given the excellent stability of lanthanide-DOTA complexes and high thermal sensitivity, TmDOTA- is expected to be a good candidate for MR thermometry in vivo.

    Previously we reported the usefulness of UBC{sup TM} test compared to urinary cytology for diagnosis of transitional cell carcinoma (TCC) of the bladder in patients with hematuria. Now we evaluated the usefulness of the UBC{sup TM} test for diagnosis of recurred urinary bladder cancer. 146 patients with hematuria were included in our study. UNC{sup TM} test (IDL Biotech, Sweden) were assayed in mid-stream urine according to the ordinary assay protocol. 33 patients were confirmed as TCC by cystoscopic examination and underwent transurethral resection (Group A). Other patients had various benign urinary tract conditions (Group B). Samples were considered positive as the UBC concentration was greater than 12 {mu} g/L. We compared UBC{sup TM} level with previous value 6 months later in patients whom diagnosed with TCC. UBC levels were significantly different between group A (95.9{+-}166.4 {mu} g/L) and group B (19.2{+-}85.6 {mu} g/L) (p<0.001). Sensitivity for diagnosis of TCC was 78.8% (26/33) in UBC test and 39.4% (13/33) in cytology (p<0.05). Specificity for diagnosis of TCC was 82.5% (80/97) in UBC{sup TM} test and 100% (97/97) in cytology. UBC{sup TM} test was significantly more sensitive in stage Ta. T{sub 1} tumors (80 vs 20 %, p<0.05) ad in grade I (80% vs 10%, p<0.05) than cytology, UBC{sup TM} test showed tendency to be more sensitive as the stage and grade was higher (80% in Ta, 83.3% in T1 and 100% in T2, 80% in Grade I, 85.7% in Grade II and 100% in Grade III). We follow-up UBC{sup TM} test in 5 patients after 6 months. UBC{sup TM} levels and recurrence were correlated in 4 patient (80%). Follow-up levels of UBC{sup TM} were increased in two recurred patients and normalized in non-recurred patients. One patient showed increased level of UBC{sup TM} test but clinically no evidence of recurrence. Although Also our patients were small, UBC{sup TM} test may be useful method for detecting the recurrence of TCC and further follow-up is necessary.

    The optimal excitation pulse repetition rates (PRRs) for a gas-discharge Tm-vapour laser with indirect population of upper laser levels are determined. It is shown that, under the same excitation conditions, the optimal PRRs increase with a decrease in the energy defect between the upper laser acceptor level and the nearest resonant donor level. The reasons for the limitation of the optimal PRRs in Tm-vapour laser are discussed. It is shown that the maximum average power of Tm-vapour laser radiation may exceed several times the Cu-vapour laser power under the same excitation conditions and in identical gas-discharge tubes.

    Prototypes (social images) have been shown to influence behaviour, which is likely to depend on the type of image. Prototype evaluation is based on (un)desirable characteristics related to that image. By an elicitation procedure we examined which adjectives are attributed to specific drinker prototypes. In total 149 young Dutch adults (18-25 years of age) provided adjectives for five drinker prototypes: abstainer, moderate drinker, heavy drinker, tipsy, and drunk person. Twenty-three unique adjectives were found. Multilevel latent class cluster analysis revealed six adjective clusters, each with unique and minor overlapping adjectives: 'negative, excessive drinker,' 'moderate, responsible drinker,' 'funny tipsy drinker,' 'determined abstainer cluster,' 'uncontrolled excessive drinker,' and 'elated tipsy cluster.' In addition, four respondent classes were identified. Respondent classes showed differences in their focus on specific adjective clusters. Classes could be labelled 'focus-on-control class,' 'focus-on-hedonism class,' 'contrasting-extremes-prototypes class,' and 'focus-on-elation class.' Respondent classes differed in gender, educational level and drinking behaviour. The results underscore the importance to differentiate between various prototypes and in prototype adjectives among young adults: subgroup differences in prototype salience and relevance are possibly due to differences in adjective labelling. The results provide insights into explaining differences in drinking behaviour and could potentially be used to target and tailor interventions aimed at lowering alcohol consumption among young adults via prototype alteration.

    Background TM4SF1 is overexpressed in pancreatic ductal adenocarcinoma (PDAC) and affects the development of this cancer. Also, multidrug resistance (MDR) is generally associated with tumor chemoresistance in pancreatic cancer. However, the correlation between TM4SF1 and MDR remains unknown. This research aims to investigate the effect of TM4SF1 on gemcitabine resistance in PDAC and explore the possible molecular mechanism between TM4SF1 and MDR. Methods The expression of TM4SF1 was evaluated in pancreatic cancer cell lines and human pancreatic duct epithelial (HPDE) cell lines by quantitative RT-PCR. TM4SF1 siRNA transfection was carried out using Hiperfect transfection reagent to knock down TM4SF1. The transcripts were analyzed by quantitative RT-PCR, RT-PCR and western blotting for further study. The cell proliferation and apoptosis were obtained to investigate the sensitivity to gemcitabine of pancreatic cancer cells after silencing TM4SF1 in vitro. We demonstrated that cell signaling of TM4SF1 mediated chemoresistance in cancer cells by assessing the expression of multidrug resistance (MDR) genes using quantitative RT-PCR. In vivo, we used orthotopic pancreatic tumor models to investigate the effect of proliferation after silencing TM4SF1 by a lentivirus-mediated shRNA in MIA PaCa-2 cell lines. Results The mRNA expression of TM4SF1 was higher in seven pancreatic cancer cell lines than in HPDE cell lines. In three gemcitabine-sensitive cell lines (L3.6pl, BxPC-3, SU86.86), the expression of TM4SF1 was lower than that in four gemcitabine-resistant cell lines (MIA PaCa-2, PANC-1, Hs766T, AsPC-1). We evaluated that TM4SF1 was a putative target for gemcitabine resistance in pancreatic cancer cells. Using AsPC-1, MIA PaCa-2 and PANC-1, we investigated that TM4SF1 silencing affected cell proliferation and increased the percentages of cell apoptosis mediated by treatment with gemcitabine compared with cells which were treated with negative control. This resistance was

    Remote sensing systems were used to monitor forest decline damage suspected of being due to air pollution. Field activities and aircraft overflights were centered on montane spruce/fir forest sites. Using aircraft data acquired with the Thematic Mapper Simulator (TMS) and LANDSAT Thematic Mapper (TM) during the growing season, extensive areas of forest decline damage were accurately mapped. Seven levels of decline damage are discrininated and mapped and the levels of discriminated damage agree well (rsq-0.94) with visual assessment conducted on the ground. New areas of high damage were discovered. A band ratio (TM5/TM4) is most useful in discriminating and quantifying the various levels of forest decline damage.

    The Landsat archive provides more than 35 years of uninterrupted multispectral remotely sensed data of Earth observations. Since 1972, Landsat missions have carried different types of sensors, from the Return Beam Vidicon (RBV) camera to the Enhanced Thematic Mapper Plus (ETM+). However, the Thematic Mapper (TM) sensors on Landsat 4 (L4) and Landsat 5 (L5), launched in 1982 and 1984 respectively, are the backbone of an extensive archive. Effective April 2, 2007, the radiometric calibration of L5 TM data processed and distributed by the U.S. Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) was updated to use an improved lifetime gain model, based on the instrument's detector response to pseudo-invariant desert site data and cross-calibration with the L7 ETM+. However, no modifications were ever made to the radiometric calibration procedure of the Landsat 4 (L4) TM data. The L4 TM radiometric calibration procedure has continued to use the Internal Calibrator (IC) based calibration algorithms and the post calibration dynamic ranges, as previously defined. To evaluate the "current" absolute accuracy of these two sensors, image pairs from the L5 TM and L4 TM sensors were compared. The number of coincident image pairs in the USGS EROS archive is limited, so the scene selection for the cross-calibration studies proved to be a challenge. Additionally, because of the lack of near-simultaneous images available over well-characterized and traditionally used calibration sites, alternate sites that have high reflectance, large dynamic range, high spatial uniformity, high sun elevation, and minimal cloud cover were investigated. The alternate sites were identified in Yuma, Iraq, Egypt, Libya, and Algeria. The cross-calibration approach involved comparing image statistics derived from large common areas observed eight days apart by the two sensors. This paper summarizes the average percent differences in reflectance estimates obtained between the

  18. Effect of Tm substitution on the magnetic properties and local magnetic anisotropy of amorphous Fe80-xTm xB20 ribbons

    International Nuclear Information System (INIS)

    We have carried out magnetic and Moessbauer studies of amorphous Fe80-xTm xB20 alloys (0 ≤ x ≤ 16). With an increasing Tm content, both the Curie temperature T C and the magnetic moment of Fe atom μ Fe decrease. We have extracted the value of exchange constant A from T C and that of the local magnetic anisotropy constant K L from the coercivity. Moessbauer studies were performed in a transmission geometry and also using the conversion electron spectroscopy. Both Moessbauer spectrometry techniques show that the average hyperfine field decreases linearly with the addition of rare-earth

  2. Measurement and analysis for neutron resonance parameters of 169Tm below 100 eV

    International Nuclear Information System (INIS)

    As part of nuclear data library, neutron resonance parameter (NRP) plays a very important part in the application for national defense, industrial production and theoretical research. For some reason, there are no such research conditions for NRP in China, either experimental or theoretical. The analysis of NRP should base on experimental data, so a total cross-section measurement was done on the Pohang Neutron Facility (PNF), yielding a new set of transmission data of 169Tm below 100 eV, as well as a new set of NRP of 169Tm using SAMMY code. Taking all data collected for 169Tm NRP into consideration, a new set of 169Tm NPR was evaluated and recommended. After this work, the methodology and analyzing-flow for NRP evaluation were summarized, as a technological reservation for the future work. (authors)

    ABB CE has established an excellent track record of reliability for its current fuel designs and has developed the TurboTM fuel design to continue to maintain this excellent performance. The heart of the TurboTM fuel design is an advanced Zircaloy spacer grid with rod support features that make the grid more robust relative to grid-to-rod fretting. The author describes the dual bundle endurance test of the TurboTM design co resident with a standard design assembly. This endurance test was run in ABB CE's Test Facility 2 (TF-2) at reactor operating pressure and temperature, and mechanical design flow. The test results demonstrate the superior performance of the TurboTM design, indicating at least a factor of 14 reduction in the potential for grid-to-rod fretting

    For BOReal Ecosystem-Atmosphere Study (BOREAS), the level-3p Landsat Thematic Mapper (TM) data were used to supplement the level-3s Landsat TM products. Along with the other remotely sensed images, the Landsat TM images were collected in order to provide spatially extensive information over the primary study areas. This information includes radiant energy, detailed land cover, and biophysical parameter maps such as Fraction of Photosynthetically Active Radiation (FPAR) and Leaf Area Index (LAI). Although very similar to the level-3s Landsat TM products, the level-3p images were processed with ground control information, which improved the accuracy of the geographic coordinates provided. Geographically, the level-3p images cover the BOREAS Northern Study Area (NSA) and Southern Study Area (SSA). Temporally, the four images cover the period of 20-Aug-1988 to 07-Jun-1994. Except for the 07-Jun-1994 image, which contains seven bands, the other three contain only three bands.

    A transverse-magnetic-pass (TM-pass) optical polarizer based on Cu complementary metal-oxide-semiconductor technology platform is proposed and analyzed using the 2-D method-of-lines numerical model. In designing the optimum configuration for the polarizer, it was found that the metal-insulator-metal (MIM) polarizer structure is superior compared to the insulator-metal-insulator polarizer structure due to its higher polarization extinction ratio (PER) and low insertion loss. An optimized MIM TM-pass polarizer exhibits simulated long wavelength pass filter characteristics of > ?1.2 ?m, with fundamental TM 0 and TE 0 mode transmissivity of >70% and <5%, respectively, and with PER ?11.5 dB in the wavelength range of 1.2-1.6 ?m. The subwavelength and submicrometer features of this TM-polarizer are potentially suitable for compact and low power photonics integrated circuit implementation on silicon-based substrates. © 1989-2012 IEEE.

    Transmembrane-4-L6 family 1 (TM4SF1) is upregulated in colorectal carcinoma (CRC). However, the mechanism leading to inhibition of the TM4SF1 is not known. In the present study, we investigated the regulation of TM4SF1 and function of microRNAs (miRNAs) in CRC invasion and metastasis. We analyzed 60 colon cancers and paired normal specimens for TM4SF1 and miRNA-9 (miR-9) expression using quantitative real-time PCR. A bioinformatics analysis identified a putative miR-9 binding site within the 3'-UTR of TM4SF1. We also found that TM4SF1 was upregulated in CRC tissues and CRC cell lines. The expression of TM4SF1 was positively correlated with clinical advanced stage and lymph node metastasis. Moreover, a luciferase assay revealed that miR-9 directly targeted 3'-UTR-TM4SF1. Overexpression of miR-9 inhibited expression of TM4SF1 mRNA and protein, wound healing, transwell migration and invasion of SW480 cells, whereas, overexpression of anti-miR-9 and siRNA-TM4SF1 inversely regulated the TM4SF1 mRNA and protein level in HCT116 cells. Furthermore, miR-9 suppressed not only TM4SF1 expression but also MMP-2, MMP-9 and VEGF expression. In clinical specimens, miR-9 was generally down-regulated in CRC and inversely correlated with TM4SF1 expression. These results suggest that miR-9 functions as a tumor-suppressor in CRC, and that its suppressive effects mediate invasion and metastasis by inhibition of TM4SF1 expression. Our results also indicate that miR-9 might be a novel target for the treatment of CRC invasion and metastasis. PMID:26983891

  10. The role of upstream sequences in selecting the reading frame on tmRNA

    Directory of Open Access Journals (Sweden)

    Dewey Jonathan D

    2008-06-01

    Full Text Available Abstract Background tmRNA acts first as a tRNA and then as an mRNA to rescue stalled ribosomes in eubacteria. Two unanswered questions about tmRNA function remain: how does tmRNA, lacking an anticodon, bypass the decoding machinery and enter the ribosome? Secondly, how does the ribosome choose the proper codon to resume translation on tmRNA? According to the -1 triplet hypothesis, the answer to both questions lies in the unique properties of the three nucleotides upstream of the first tmRNA codon. These nucleotides assume an A-form conformation that mimics the codon-anticodon interaction, leading to recognition by the decoding center and choice of the reading frame. The -1 triplet hypothesis is important because it is the most credible model in which direct binding and recognition by the ribosome sets the reading frame on tmRNA. Results Conformational analysis predicts that 18 triplets cannot form the correct structure to function as the -1 triplet of tmRNA. We tested the tmRNA activity of all possible -1 triplet mutants using a genetic assay in Escherichia coli. While many mutants displayed reduced activity, our findings do not match the predictions of this model. Additional mutagenesis identified sequences further upstream that are required for tmRNA function. An immunoblot assay for translation of the tmRNA tag revealed that certain mutations in U85, A86, and the -1 triplet sequence result in improper selection of the first codon and translation in the wrong frame (-1 or +1 in vivo. Conclusion Our findings disprove the -1 triplet hypothesis. The -1 triplet is not required for accommodation of tmRNA into the ribosome, although it plays a minor role in frame selection. Our results strongly disfavor direct ribosomal recognition of the upstream sequence, instead supporting a model in which the binding of a separate ligand to A86 is primarily responsible for frame selection.

  11. Absorptions and emissions for the TmCl63- ion in Cs2NaTmCl6

    International Nuclear Information System (INIS)

    In this work we report both experimental and theoretical studies regarding the Cs2naTmCl6 elpasolite-type system, for which we have an updated database from linear and nonlinear optics. Both the absorption and emission spectra for this system are rather complicated and a generalized vibronic crystal field-closure-ligand polarization calculation model has been employed to rationalize the observed spectral intensities. The calculation has ben carried out by neglecting the interaction among the internal and the external vibrations and theoretical calculations have been performed with reference to both the emissions 3H4(Γi) → 3F4(Γj) and the absorptions 3H6(A1) → 3F4Γi, 1G4(Γi , 3H5(Γl) with Γk (k = i,j) = A1, E, T1, T2 and Γl=E, aT1, bT1, T2. The advantages and disadvantages of our model calculation are discussed in the text, and despite the simplicity of the model it is shown that it has got some utility and flexibility to gain understanding in these complex phenomena.

    Radioactive ion beams (RIBs) of {sup 17}F and {sup 18}F are of interest for investigation of astrophysical phenomena such as the hot CNO cycle and the rp stellar nuclear synthesis processes. In order to generate useful beam intensities of atomic F{sup {minus}}, the species must be efficiently and expediently released from the target material, thermally dissociated from fluoride release products during transport to the ionization chamber of the ion source, and efficiently ionized in the source upon arrival. The authors have conceived and evaluated two prototype negative ion sources for potential use for RIB generation: (1) a direct extraction source and (2) a kinetic ejection source. Both sources utilize Cs vapor to enhance F{sup {minus}} formation. The mechanical design features, operational parameters, ionization efficiencies for forming atomic F{sup {minus}} and delay times for transport of F and fluoride compounds for the respective sources are presented. The efficiency {eta} for formation and extraction of F{sup {minus}} for the direct extraction negative ion source is found to be {eta} {approximately} 1.0% while the characteristic delay time {tau} for transport of F and fluorides through the source is typically, {eta} {approximately} 120s; the analogous efficiencies and delay times for the kinetic ejection negative ion source are, respectively: {eta} = {approximately}3.2% and {tau} = {approximately}70s.

  13. Prototype fast breeder reactor main options

    International Nuclear Information System (INIS)

    Fast reactor programme gets importance in the Indian energy market because of continuous growing demand of electricity and resources limited to only coal and FBR. India started its fast reactor programme with the construction of 40 MWt Fast Breeder Test Reactor (FBTR). The reactor attained its first criticality in October 1985. The reactor power will be raised to 40 MWt in near future. As a logical follow-up of FBTR, it was decided to build a prototype fast breeder reactor, PFBR. Considering significant effects of capital cost and construction period on economy, systematic efforts are made to reduce the same. The number of primary and secondary sodium loops and components have been reduced. Sodium coolant, pool type concept, oxide fuel, 20% CW D9, SS 316 LN and modified 9Cr-1Mo steel (T91) materials have been selected for PFBR. Based on the operating experience, the integrity of the high temperature components including fuel and cost optimization aspects, the plant temperatures are recommended. Steam temperature of 763 K at 16.6 MPa and a single TG of 500 MWe gross output have been decided. PFBR will be located at Kalpakkam site on the coast of Bay of Bengal. The plant life is designed for 30 y and 75% load factor. In this paper the justifications for the main options chosen are given in brief. (author). 2 figs, 2 tabs

    Rapid prototyping (RP) describes the customized production of solid models using 3D computer data. Over the past decade, advances in RP have continued to evolve, resulting in the development of new techniques that have been applied to the fabrication of various prostheses. RP fabrication technologies include stereolithography (SLA), fused deposition modeling (FDM), computer numerical controlled (CNC) milling, and, more recently, selective laser sintering (SLS). The applications of RP techniques for dentistry include wax pattern fabrication for dental prostheses, dental (facial) prostheses mold (shell) fabrication, and removable dental prostheses framework fabrication. In the past, a physical plastic shape of the removable partial denture (RPD) framework was produced using an RP machine, and then used as a sacrificial pattern. Yet with the advent of the selective laser melting (SLM) technique, RPD metal frameworks can be directly fabricated, thereby omitting the casting stage. This new approach can also generate the wax pattern for facial prostheses directly, thereby reducing labor-intensive laboratory procedures. Many people stand to benefit from these new RP techniques for producing various forms of dental prostheses, which in the near future could transform traditional prosthodontic practices.

  16. A low cost MRI permanent magnet prototype

    International Nuclear Information System (INIS)

    Here we present the proceedings in designing and constructing a low cost, friendly use, Magnetic Resonance Imaging (MRI) prototype magnet; 55 cmx45 cmx30 cm in size scaleable to full body; with a C-shaped assembly to provide open access to the 10 cm C-gap; operational at 0.22 Tesla where the low field increments the tissue contrast; structured with methodically selected and strategically positioned permanent magnets to reach the required field homogeneity as well as to be practically free of maintenance; and having iron flux return to leave an extremely low fringe field. The magnetic flux is funneled through the iron and focused by carefully designed and finely machined iron pole faces of 8.9 cm radius to create a homogeneity of less than 20 parts per million (PPM), without shimming, in a roughly 1.3 cm by 2 cm main axes oval region. An image of an okra plant was taken to test its performance

    The aging investigation results of CMS EMU prototype chambers are presented. Aging tests under sustained irradiation by a 90Sr 2 Ci were performed with three working gas mixtures Ar( 30%)+CO2( 50%)+CF4( 20%), Ar( 30%)+CO2( 70%) and Ar( 40%)+CO2( 50%)+CF4( 10%). For Ar( 30%)+CO2( 50%)+CF4( 20%) mixture gas gain reduction was not observed up to the accumulated charge Q = 13.56 C/cm. However, the dark current in the chamber was noticeable starting already from Q = 2 C/cm. The absence of the CF4 ( in the Ar/CO2 gas mixture) caused fast aging deterioration, and Q = 0.2 C/cm was enough to obtain 50% of the gas gain reduction. In the test with Ar( 40%)+CO2( 50%)+CF4( 10%) mixture the gas gain reduction and the dark current increase were not observed up to Q = 13.35 C/cm. Reduction of the gas flow rate to 0.1 volume per day caused 50% of the gain decrease due to the gas pollution by fragments of dissociated gas molecules. The gain restored after switching back to the 1 volume per day flow rate. Studies with electroni...

    If robots are to successfully interact with humans, they need to measure, quantify and respond to the emotions we produce. Similar to humans, the perceptual cue inputs to any modelling that allows this will be based on behavioural expression and body activity features that are prototypical of each emotion. However, the likely employment of such robots in different cultures necessitates the tuning of the emotion feature recognition system to the specific feature profiles present in these cultures. The amount of tuning depends on the relative convergence of the cross-cultural mappings between the emotion feature profiles of the cultures where the robots will be used. The GRID instrument and the cognitive corpus linguistics methodology were used in a contrastive study analysing a selection of behavioural expression and body activity features to compare the feature profiles of joy, sadness, fear and anger within and between Polish and British English. The intra-linguistic differences that were found in the profile of emotion features suggest that weightings based on this profile can be used in robotic modelling to create emotion-sensitive socially interacting robots. Our cross-cultural results further indicate that this profile of features needs to be tuned in robots to make them emotionally competent in different cultures. PMID:25484993

  19. Rapid Prototyping Modules for Remote Engineering Applications

    Full Text Available This contribution describes the concept and implementation for an integration of microcontroller and FPGA based Rapid Prototyping modules into a Remote Lab system. This implementation enables a Web-based access to electro-mechanical models. A student uploads a source file implementation to the Remote Lab server in order to test an implementation directly within a hardware environment. The Remote Lab server offers the interfaces to integrate specific project and hardware plug-ins. These plug-ins access a hardware specific software environment to automatically compile and program the resulting firmware. To stimulate this design, the Remote Lab server exchanges digital signals via a serial interface. To allow the student to compare architectures of different designs using the same hardware model, a specific controller (using the Remote Lab interface can be selected. For this, an IP-based multiplexer provides the control connection between the respective controller and the hardware model. In our contribution we would like to give examples of such a complex design task and how the students can use different tools during several design steps.

  20. A prototype switched Ethernet data acquisition system

    International Nuclear Information System (INIS)

    A prototype switched Ethernet data acquisition system has been built up and successfully operated in HL-1M tokamak experiments. The system is based on a switched high bandwidth Ethernet network with which the CAMAC crates are directly interfaced. It takes the advanced features of LAN switch and Ethernet CAMAC controller (ECC 1365 MK III, HYTEC product) to avoid the rewriting of CAMAC driver for an individual computer system and to ensure high data transmission rate between CAMAC system and host computers on the network. It is a new approach to DAS system architecture and provides a solution for a well-known bottleneck problem in traditional distributed DAS system for fusion research. An average throughput of the test system reaches over 100 Mbps. The system features also an easy and low cost migration from traditional distributed DAS system. In the paper, the hardware configuration, software structure, performance of the system and the method of migrating from current DAS system are discussed in detail. (orig.)
