    To reduce the beam losses when preparing high intensity proton beam for the CERN Neutrino to Gran Sasso (CNGS) facility, a new Multi-Turn extraction (MTE) scheme has been implemented in the PS, to replace the present Continuous Transfer (CT) to the SPS. Industrial off-the-shelf components have been used for the low-level part of the MTE kicker control system. National Instruments PXI systems are used to control the high voltage pulse generators and a SIEMENS programmable logic controller (PLC) handles the centralised oil cooling and gas insulation sub-systems

    Dispersion and beam optics measurements were carried out in the transfer line between the CERN PS and SPS for the new Multi-Turn Extraction beam. Since the extraction conditions of the four islands and the core are different and strongly dependent on the non-linear effects used to split the beam in the transverse plane, a special care was taken during the measurement campaigns. Furthermore, an appropriate strategy was devised to minimize the overall optical mismatch at SPS injection. All this led to a new optical configuration that will be presented in the paper.

    The losses created by the proposed Multi-Turn Extraction (MTE) at the CERN PS induce high activation of the magnetic extraction septum due to the de-bunched longitudinal beam structure requested to transfer the beam to the SPS. A mitigation measure is under study aiming at localizing the losses in a well-shielded area by shadowing the magnetic extraction septum thanks to a septum-like passive device. Such a solution is based on a so-called dummy septum, a blade which absorbs particles during the rise time of the extraction kickers for MTE beams. The efficiency of the scheme is presented in this paper. The quantitative estimate is based on detailed simulations that analyze the beam-matter interaction and provide a determination of the shadowing effect of the dummy septum.

    The CERN PS utilises a Multi-Turn Extraction (MTE) scheme to stretch the beam pulse length to optimise the filling process of the SPS. MTE is a novel technique to split a beam in transverse phase space into nonlinear stable islands. The recent experimental results indicate that the positions of the islands depend on the total beam intensity. Particle simulations have been performed to understand the detailed mechanism of the intensity dependence. The analysis carried out so far suggests space charge effects through image charges and image currents on the vacuum chamber and the magnets iron cores dominate the observed behaviour. In this talk, the latest analysis with realistic modelling of the beam environment is discussed and it is shown how this further improves the understanding of intensity effects in MTE.

    Within CERN's accelerator complex, the extraction from the Proton Synchrotron to the Super Proton Synchrotron has been done using the so-called ``Continuous Transfer" (CT) method since the 1970's. A new technique, known as Multi-Turn Extraction (MTE), has now been implemented and is in full operation. This report examines a holistic performance analysis of the novel technique in multiple aspects of the accelerator complex, as well as a direct comparison with its predecessor, CT, from the implementation of MTE in 2010 until the end of 2015.

    A protection septum has been installed in the CERN PS section 15 in order to mitigate irradiation of the magnetic septum 16 for fast extractions towards the SPS. Impedance studies have been performed, showing that beams circulating in the septum during extraction generate sharp resonances in the coupling impedance. Impedance measurements with the wire technique have been performed, showing a good agreement with simulations. Instability rise times of trapped modes have been evaluated and compared to extraction duration. Solutions for reducing the impact on the stability of the beam have been considered

  7. Trapped modes in a dummy extraction septum for CERN Proton Synchrotron

    2014-01-01

    The term trapped mode is usually referred to a mode that can not propagate in the beam pipe, but is localized in a particular region inside the device, producing narrow resonances peaks in the coupling impedance. They can be excited by the presence of discontinuities inside different devices of an accelerator, producing unwanted beam instabilities. It is therefore important to identify trapped modes, especially for new elements to be installed in a high-intensity accelerator. We present a recent study of the coupling impedance due to trapped modes in a new extraction septum that will be installed in the CERN Proton Synchrotron in the framework of PS Multi-turn extraction (MTE) commissioning. Simulation and theoretical calculations were performed in order to understand performance limitations of the machine, to find cures to reduce the instabilities, and to evaluate beam-induced heating.

    2004-01-01

    Recently a novel approach to perform multi-turn extraction was proposed based on beam splitting in the transverse phase space by means of trapping inside stable islands. During the year 2002, preliminary measurements at the CERN Proton Synchrotron with a low-intensity, singlebunch, proton beam, confirmed the possibility of generating various beamlets starting from a single Gaussian beam. The experimental campaign continued also during the year 2003 to assess a number of key issues, such as the feasibility of trapping with high-intensity beam and capture efficiency. The experimental results are presented and discussed in detail in this paper.

    The performance of the CERN Proton Synchrotron (PS) has been constantly increasing over the years both in terms of beam parameters (intensity and brightness) and beam manipulations (transverse and longitudinal splitting). This implies a very good knowledge of the linear and non-linear model of the ring. In this paper we report on a detailed campaign of beam measurements based on turn-by-turn orbit data aimed at measuring the optics in several conditions as well as the resonance driving terms.

    For five decades, the CERN Bulletin has been a staple of the Organization. As CERN has grown as a laboratory and a community, the Bulletin has been there to cover each development as it happens. In honour of the publication's 50th anniversary, we're taking a trip through CERN’s history via the headings and hidden corners of its internal newsletter.     It's 1965 and CERN - now 11 years old - has matured from a simple lab to a fledgling community. While news could once spread in a single afternoon, CERN's growth necessitated a new approach to the sharing of internal information. Meanwhile, the CERN Courier - the only publication in town - was approaching a more global physics audience – an audience for whom CERN road closures were not breaking news. And so, in March 1965, the Weekly Bulletin was born. What was meant as a simple newsletter of events and internal announcements quickly developed into a wider source of news about CERN....

  12. Non-local Fast Extraction from the CERN SPS at 100 and 440 GeV

    The Long Straight Section 2 (LSS2) of the CERN SPS is connected with the North Area (NA), to which the beam to date has always been extracted using a resonant extraction technique. For new proposed short- and long-baseline neutrino experiments, a fast single turn extraction to this experimental area is required. As there are no kickers in LSS2, and the integration of any new kickers with the existing electrostatic septum would be problematic, a solution has been developed to fast extract the beam using non-local extraction with other SPS kickers. Two different kicker systems have been used, the injection kicker in LSS1 and the stronger extraction kicker in LSS6 to extract 100 and 440 GeV beam, respectively. For both solutions a large emittance beam was extracted after 5 or 9 full betatron periods. The concept and simulation details are presented with the analysis of the aperture and beam loss considerations and experimental results collected during a series of beam tests.

  16. Transverse beam splitting made operational: Key features of the multiturn extraction at the CERN Proton Synchrotron

    2017-06-01

    Full Text Available Following a successful commissioning period, the multiturn extraction (MTE at the CERN Proton Synchrotron (PS has been applied for the fixed-target physics programme at the Super Proton Synchrotron (SPS since September 2015. This exceptional extraction technique was proposed to replace the long-serving continuous transfer (CT extraction, which has the drawback of inducing high activation in the ring. MTE exploits the principles of nonlinear beam dynamics to perform loss-free beam splitting in the horizontal phase space. Over multiple turns, the resulting beamlets are then transferred to the downstream accelerator. The operational deployment of MTE was rendered possible by the full understanding and mitigation of different hardware limitations and by redesigning the extraction trajectories and nonlinear optics, which was required due to the installation of a dummy septum to reduce the activation of the magnetic extraction septum. This paper focuses on these key features including the use of the transverse damper and the septum shadowing, which allowed a transition from the MTE study to a mature operational extraction scheme.

    In 2006 the protection devices upstream of the septa in both extraction channels of the CERN SPS to the LHC were installed. Since then, new beam parameters have been proposed for the SPS beam towards the LHC in the framework of the LIU project. The mechanical parameters and assumptions on which these protection devices presently have been based, need validation before the new upgraded versions can be designed and constructed. The paper describes the design assumptions for the present protection device and the testing program for the TPSG4 at HiRadMat to validate them. Finally the requirements and the options to upgrade both extraction protection elements in the SPS are described.

  5. New Spill Control for the Slow Extraction in the Multi-Cycling SPS

    CERN Document Server

    Kain, Verena; Effinger, Ewald

    2016-01-01

    The flux of particles slow extracted with the 1/3 integer resonance from the Super Proton Synchrotron at CERN was previously controlled with a servo-spill feedback system which acted on the horizontal tune such as to keep the spill rate as constant as possible during the whole extraction time. The current in two servo-quadrupoles was modulated as a function of the difference between the measured and the desired spill rate. With servo quadrupoles at a single location in the SPS ring and the SPS in multi-cycling mode, the trajectory of the slow extracted beam was seen to change from cycle to cycle depending on the current applied by the servo feedback. Hence this system was replaced by a feed-forward tune correction using the main SPS quadrupoles. In this way the spill control can now be guaranteed without changing the trajectory of the extracted beam. This paper presents the algorithm and implementation in the control system and summarizes the advantages of the new approach. The obtained spill characteristics ...

    In case of a resistive transition (quench), fast and reliable extraction of the magnetic energy, stored in the superconducting coils of the electromagnets of a particle collider, represents an important part of its magnet protection system. In general, the quench detectors, the quench heaters and the cold by-pass diodes across each magnet, together with the energy extraction facilities provide the required protection of the quenching superconductors against damage due to local energy dissipation. In CERN's LHC machine the energy stored in each of its eight superconducting dipole chains exceeds 1300 MJ. Following an opening of the extraction switches this energy will be absorbed in large extraction resistors located in the underground collider tunnel or adjacent galleries, during the exponential current decay. Also the sixteen, 13 kA quadrupole chains (QF, QD) and more than one hundred and fifty, 600 A circuits of the corrector magnets will be equipped with extraction systems.

This discovery served as the turning point for CERN from the point of view of the self-confidence of its physicists, the confidence of its fund-raisers, and its reputation in the US. However, this feat did not come as easy for CERN. Rivalry with the US revealed complexities. Nevertheless in the end, CERN physicists became the more successful. Recognizing this, US physicists agreed to collaborate with CERN physicists. Today, there is no more political competition over accelerators between the two groups. (Edited abstract).

    A comprehensive study of beam formation and beam transport has been initiated in order to improve the performance of the CERN heavy ion injector, Linac3. As part of this study, the ion beam extraction system of the CERN GTS-LHC 14.5 GHz Electron Cyclotron Resonance Ion Source (ECRIS) has been modelled with the ion optical code IBSimu. The simulations predict self-consistently the triangular and hollow beam structures which are often observed experimentally with ECRIS ion beams. The model is used to investigate the performance of the current extraction system and provides a basis for possible future improvements. In addition, the extraction simulation provides a more realistic representation of the initial beam properties for the beam transport simulations, which aim to identify the performance bottle necks along the Linac3 low energy beam transport. The results of beam extraction simulations with Pb and Ar ion beams from the GTS-LHC will be presented and compared with experimental observations.

    The optimization of performance characteristics in turning process can be achieved through selection of proper machining parameters. It is well known that many researchers have successfully reported the optimization of single performance characteristic. Nevertheless, the multi-objective optimization can be difficult and challenging to be studied due to its complexity in analysis. This is because an improvement of one performance characteristic may lead to degradation of other performance characteristic. As a result, the study of multi-objective optimization in CNC turning of S45C carbon steel has been attempted in this paper through Taguchi and Grey Relational Analysis (GRA) method. Through this methodology, the multiple performance characteristics, namely; surface roughness, material removal rate (MRR), tool wear, and power consumption; can be optimized simultaneously. It appears from the experimental results that the multiple performance characteristics in CNC turning was achieved and improved through the methodology employed. (paper)

    In the framework of the LIU project, new septa magnets have been designed between CERN's PS booster (PSB) extraction and PS injection. The upgraded devices are to deal with the increased beam energy from 1.4 to 2 GeV at extraction of the PSB. The direct drive recombination septa in the PSB transfer line to the PS and the eddy current PS injection septum together with a bumper at injection have been investigated using finite-element software. For the recombination magnets, an increase in magnet length is sufficient to obtain the required deflection; however, for the PS injection elements, a more novel solution is necessary to also achieve increased robustness to extend the expected lifetime of the pulsed device. The injection septum will share the same vacuum vessel with an injection bumper, and both magnets will be located adjacent to each other. The new PS injection magnet will be the first septum operated at CERN based on eddy current technology. The magnetic modeling of the devices, the comparison of the p...

  1. Multi-turn multi-gap transmission line resonators - Concept, design and first implementation at 4.7T and 7T.

    2016-12-01

    A novel design scheme for monolithic transmission line resonators (TLRs) is presented - the multi-turn multi-gap TLR (MTMG-TLR) design. The MTMG-TLR design enables the construction of TLRs with multiple turns and multiple gaps. This presents an additional degree of freedom in tuning self-resonant TLRs, as their resonance frequency is fully determined by the coil geometry (e.g. diameter, number of turns, conductor width, etc.). The novel design is evaluated at 4.7T and 7T by simulations and experiments, where it is demonstrated that MTMG-TLRs can be used for MRI, and that the B 1 distribution of MTMG-TLRs strongly depends on the number and distribution of turns. A comparison to conventional loop coils revealed that the B 1 performance of MTMG-TLRs is comparable to a loop coil with the same mean diameter; however, lower 10g SAR values were found for MTMG-TLRs. The MTMG-TLR design is expected to bring most benefits at high static field, where it allows for independent size and frequency selection, which cannot be achieved with standard TLR design. However, it also enables more accurate geometric optimization at low static field. Thereby, the MTMG-TLR design preserves the intrinsic advantages of TLRs, i.e. mechanical flexibility, high SAR efficiency, mass production, and coil miniaturization. Copyright © 2016 The Authors.

  2. Design of Injection and Extraction Systems with Optimisation of Lattice and Layout for the CERN PS2 Synchrotron

    CERN Document Server

    Bartmann, W

    2009-01-01

    The CERN Proton Synchrotron PS2 is one of the foreseen accelerators for the LHC injector upgrade. This upgrade aims first at increasing the instantaneous luminosity of LHC and second at providing a reliable beam for the CERN accelerator complex. From this aspect, the main characteristics of the PS2 are high reliability for high intensity beams. The goal of this thesis was the design of the machine’s lattice and injection/extraction systems meeting the constraints coming mainly from the LHC beam type but also from beam requirements of experiments at PS2 and the SPS. In the design, the given energy range together with filling schemes for different beam types and RF cogging were first used to define the circumference of the machine. Estimates on the space requirements of injection/extraction systems were made in order to divide the total machine length between arc and long straight section. Existing tunnels for transfer lines together with the minimisation of the total transfer line length favoured a race trac...

  3. Your chance to shape internal communication at CERN

    CERN Multimedia

    Effective internal communication is essential to any organization, particularly one like CERN that is host to a large, varied and geographically widespread community. The CERN Bulletin has for many years been the mainstay of internal communication at the lab, bringing you news about all aspects of life at CERN. From the 1970s to just a few years ago, the Bulletin was a print-only publication, but it has since evolved with the times to embrace the web. Moving forward, we aim to broaden the Bulletin's reach and turn it into a genuine forum for discussion within the CERN community. One of the first steps in this process is for the CERN communication group to work with the Staff Association to develop a more inclusive form of internal communication, bringing together news from the Management with news from the Association, while also playing an important social role by providing a channel for the Association’s many clubs to reach out to everyone working at CERN. This integrated approach to communic...

  5. Studies of the beam extraction system of the GTS-LHC electron cyclotron resonance ion source at CERN.

    Science.gov (United States)

    Toivanen, V; Küchler, D

    2016-02-01

    The 14.5 GHz GTS-LHC Electron Cyclotron Resonance Ion Source (ECRIS) provides multiply charged heavy ion beams for the CERN experimental program. The GTS-LHC beam formation has been studied extensively with lead, argon, and xenon beams with varied beam extraction conditions using the ion optical code IBSimu. The simulation model predicts self-consistently the formation of triangular and hollow beam structures which are often associated with ECRIS ion beams, as well as beam loss patterns which match the observed beam induced markings in the extraction region. These studies provide a better understanding of the properties of the extracted beams and a way to diagnose the extraction system performance and limitations, which is otherwise challenging due to the lack of direct diagnostics in this region and the limited availability of the ion source for development work.

    In 1970, CERN and ESO signed a collaboration agreement for the construction of the Observatory’s first telescope. That same year, ESO’s Telescope Division and Sky Atlas laboratory settled on the CERN site in Meyrin. Let’s turn back to the beginnings of this lasting and fruitful alliance.   Martin Cullum, ESO physicist from 1973 to 2009 In 1974, when I attended my first international conference on behalf of ESO, the first thing people asked was: “Where are you from?” “ESO,” I would say. The response: ‘'What on Earth is ESO?” Nowadays, people I meet seem to know more about ESO than I do! It is clear that ESO profited enormously from its sojourn at CERN. The wise decision of the ESO Director General at the time, Adriaan Blaauw, to move to Geneva allowed ESO to build up its technical expertise to be able to build world-beating projects like the VLT, which has undoubtedly been the most exciting scientif...

  10. A mathematical model of a three-gap thyratron simulating turn-on

    International Nuclear Information System (INIS)

    Barnes, M. J.; Wait, G.D.

    1993-06-01

    Kicker magnets are required for all ring-to-ring transfers in the 5 rings of the proposed KAON factory synchrotron. The kick must rise/fall from 1% to 99% of full strength during the time interval of gaps created in the beam (80 ns to 160 ns) so that the beam can be extracted with minimum losses. Approximately one-third of the injection and extraction kicker magnets will operate continuously at a rate of 50 pulses per second: the others operate at 10 pulses per second. The kicker magnet PFN voltages will be in the range 50kV to 80kV, hence multi-gap thyratrons will be used for the injection and extraction kicker systems. Displacement current arising from turn-on of a multi-gap thyratron flows in the external circuit and can thus increase the effective rise-time of the kick. A mathematical model of a three-gap thyratron, which includes the drift spaces, has been developed for simulating turn-on, and is described in this paper. The thyratron model has been used to investigate ways to suppress the effects of displacement current on the kick, and to reduce thyratron switching loss. A ferrite saturating inductor may be connected adjacent to each thyratron to reduce switching loss, so that thyratron life can be extended and the kick rise-time improved. This inductor can also be used to reduce the effect of anode displacement current during turn-on of a multi-gap thyratron. The research has culminated in a predicted kick rise time (1% to 99%) of less than 50 ns for a TRIUMF 10 cell prototype kicker magnet. The proposed improvements are currently being implemented on our prototype kicker system. (author). 15 refs., 11 figs

    2016-01-01

    In the frame of the LIU (LHC Injectors Upgrade) project, the CERN PS Booster is going to be renovated to host a new H⁻ charge-exchange injection from the Linac4. One important feature of the new injection scheme is the possibility to tailor a wide range of 3D emittances for CERN's different users in an intensity span in the order of 5·10⁹ to 1.6·10¹³ protons per PSB ring. This paper gives an overview of 3D multi-turn injection techniques, focusing on the future LHC beams, which aim at reaching high brightness, and on highest intensity beams (ISOLDE), where losses are the main concern. Complete RF capture simulations and transverse injection maps, including space charge effects, are presented and also intended to be used during the commissioning with Linac4.

    2013-01-01

    In 2011 the ELENA decelerator was approved as a CERN project. Initially one extraction was foreseen, which should use a kicker and a magnetic septum which can be recuperated from an earlier installation. Since then a second extraction has been approved and a new solution was studied using only electric fields to extract the beam. This will be achieved by fast pulsing a separator, allowing single-bunch but also a full single-turn extraction from ELENA towards the experiments. The extraction and transfer requirements of ELENA are described, followed by the principal differences between the magnetic and electric field concepts. The design of electrostatic focussing and bending devices for the transfer lines will be presented. Finally the field quality which can be achieved with the separator and the concept of its power supply will be discussed.

    The feasibility of extracting particles from the halo of a circulating proton beam using a bent silicon crystal has been demonstrated experimentally at the SPS for a beam energy of 120 GeV. Presently studies are conducted to understand the extraction mechanisms and the measured efficiencies. In particular the contribution of multi-pass extraction, where the particles can pass through the crystal many times before being channelled and extracted, is investigated. In a recent experiment, using a crystal especially fabricated with a finite amorphous layer on its surface, it has been proven that multi-pass extraction plays an important role. The experiment is described and the implication for further studies are discussed.

    CDD (CERN Drawings Directory) is a multi-platform utility which manages engineering drawings made in any division at CERN. The aim of CDD is not to store the graphical drawing itself, but to store a reference with some information related to the drawing. Access to this data is provided via a graphical user interface which is based upon ORACLE Forms and via WWW. Drawings following different numbering systems and different management rules can be handled by CDD. The only condition is that those particular functionalities are well defined. Several drawing systems have been identified in CERN and therefore considered when designing the application. The current version of CDD focuses on systems EST, LEP, ST-IE, SPS, ST-CE and the experiments ALICE, ATLAS, CMS and LHCb. Other CERN systems could be easily integrated upon demand.

This operation is a fruitful exchange of technology that profits both laboratories and enhances their collaboration.   On 22 July, in the occasion of the departure of the chambers from CERN, Mikhail Itkis (centre), acting Director of the JIINR visited the NA62 experimental area accompanied by Rolf Heuer (left), CERN Director General and Ferdinand Hahn, NA62 technical Co-ordinator. The NA48 drift chambers were overhauled in 2000 and employed until 2008. With a total of 110 kilometres of wire soldered to a very high degree of precision, the four drift chambers were a crucial element of the experimental kaon programme at CERN. The chambers are now moving to a new challenge as they will be re-used by the Multi Purpose Detector (MPD) experiment, under...

    When precision data from the several million Zs carefully collected over several years by the four big experiments - Aleph, Delphi, L3 and Opal - at CERN's LEP electron-positron collider have otherwise consistently underlined conventional physics, a hint of something unexplained quickly packs the seminar rooms. In 1991, the L3 experiment turned up two examples of Z decays producing a muon pair accompanied by a widely separated pair of high energy photons, with the photon pair in each case taking some 60 GeV of energy (actually 58.8 and 59.0 GeV). Nothing to get excited about at the time, but ongoing data analysis tuned into this channel. This year two more events turned up, one again with a muon pair accompanied by a 60 GeV photon pair, the other with an electron (electron-positron) pair and a 62 GeV photon pair. At first L3 preferred to keep this quiet, and the news was not announced at the major international meeting in Dallas last August. The first public announcement of the four unexplained events (out of a total of 1.6 million Z decays) came in a LEP Experiments Committee session at CERN in October

    CERN is where the web was born, and remains a hothouse of innovation in information technology (IT). In this fourth First Tuesday @ CERN, we look at industrial partnership at CERN in the IT area from several different angles. The approach taken by CERN with software licencing - a very hot topic in the world of IT - will be discussed. The benefits that CERN hardware and software suppliers gain from working with CERN will be presented, and the CERN openlab, a new approach to industrial partnership at CERN, will be covered. A novel ingredient of this First Tuesday @ CERN is that it will be run in parallel with a similar event for the business community in London, and there will be webcast presentations between the Queen Elizabeth II Conference Centre in London and CERN during the event. Thus, First Tuesday @ CERN will take on a truly European dimension, to reflect CERN's European character.

    Linac3 is the first accelerator in the heavy ion injector chain of the Large Hadron Collider (LHC), providing multiply charged heavy ion beams for the CERN experimental program. The ion beams are produced with GTS-LHC, a 14.5 GHz electron cyclotron resonance ion source, operated in afterglow mode. Improvement of the GTS-LHC beam formation and beam transport along Linac3 is part of the upgrade program of the injector chain in preparation for the future high luminosity LHC. A mismatch between the ion beam properties in the ion source extraction region and the acceptance of the following Low Energy Beam Transport (LEBT) section has been identified as one of the factors limiting the Linac3 performance. The installation of a new focusing element, an einzel lens, into the GTS-LHC extraction region is foreseen as a part of the Linac3 upgrade, as well as a redesign of the first section of the LEBT. Details of the upgrade and results of a beam dynamics study of the extraction region and LEBT modifications will be presented.

  1. Automated road network extraction from high spatial resolution multi-spectral imagery

    Science.gov (United States)

    Zhang, Qiaoping

    For the last three decades, the Geomatics Engineering and Computer Science communities have considered automated road network extraction from remotely-sensed imagery to be a challenging and important research topic. The main objective of this research is to investigate the theory and methodology of automated feature extraction for image-based road database creation, refinement or updating, and to develop a series of algorithms for road network extraction from high resolution multi-spectral imagery. The proposed framework for road network extraction from multi-spectral imagery begins with an image segmentation using the k-means algorithm. This step mainly concerns the exploitation of the spectral information for feature extraction. The road cluster is automatically identified using a fuzzy classifier based on a set of predefined road surface membership functions. These membership functions are established based on the general spectral signature of road pavement materials and the corresponding normalized digital numbers on each multi-spectral band. Shape descriptors of the Angular Texture Signature are defined and used to reduce the misclassifications between roads and other spectrally similar objects (e.g., crop fields, parking lots, and buildings). An iterative and localized Radon transform is developed for the extraction of road centerlines from the classified images. The purpose of the transform is to accurately and completely detect the road centerlines. It is able to find short, long, and even curvilinear lines. The input image is partitioned into a set of subset images called road component images. An iterative Radon transform is locally applied to each road component image. At each iteration, road centerline segments are detected based on an accurate estimation of the line parameters and line widths. Three localization approaches are implemented and compared using qualitative and quantitative methods. Finally, the road centerline segments are grouped into a

  2. Semi-Supervised Multi-View Ensemble Learning Based On Extracting Cross-View Correlation

    Directory of Open Access Journals (Sweden)

    ZALL, R.

    2016-05-01

    Full Text Available Correlated information between different views incorporate useful for learning in multi view data. Canonical correlation analysis (CCA plays important role to extract these information. However, CCA only extracts the correlated information between paired data and cannot preserve correlated information between within-class samples. In this paper, we propose a two-view semi-supervised learning method called semi-supervised random correlation ensemble base on spectral clustering (SS_RCE. SS_RCE uses a multi-view method based on spectral clustering which takes advantage of discriminative information in multiple views to estimate labeling information of unlabeled samples. In order to enhance discriminative power of CCA features, we incorporate the labeling information of both unlabeled and labeled samples into CCA. Then, we use random correlation between within-class samples from cross view to extract diverse correlated features for training component classifiers. Furthermore, we extend a general model namely SSMV_RCE to construct ensemble method to tackle semi-supervised learning in the presence of multiple views. Finally, we compare the proposed methods with existing multi-view feature extraction methods using multi-view semi-supervised ensembles. Experimental results on various multi-view data sets are presented to demonstrate the effectiveness of the proposed methods.

  3. Monitoring Evolution at CERN

    2015-01-01

    Over the past two years, the operation of the CERN Data Centres went through significant changes with the introduction of new mechanisms for hardware procurement, new services for cloud provisioning and configuration management, among other improvements. These changes resulted in an increase of resources being operated in a more dynamic environment. Today, the CERN Data Centres provide over 11000 multi-core processor servers, 130 PB disk servers, 100 PB tape robots, and 150 high performance tape drives. To cope with these developments, an evolution of the data centre monitoring tools was also required. This modernisation was based on a number of guiding rules: sustain the increase of resources, adapt to the new dynamic nature of the data centres, make monitoring data easier to share, give more flexibility to Service Managers on how they publish and consume monitoring metrics and logs, establish a common repository of monitoring data, optimise the handling of monitoring notifications, and replace the previous ...

  4. Multi-scale salient feature extraction on mesh models

    2012-01-01

    We present a new method of extracting multi-scale salient features on meshes. It is based on robust estimation of curvature on multiple scales. The coincidence between salient feature and the scale of interest can be established straightforwardly, where detailed feature appears on small scale and feature with more global shape information shows up on large scale. We demonstrate this multi-scale description of features accords with human perception and can be further used for several applications as feature classification and viewpoint selection. Experiments exhibit that our method as a multi-scale analysis tool is very helpful for studying 3D shapes. © 2012 Springer-Verlag.

  5. Simulations to investigate the eect of circuit imperfections on the slow extraction process

    The Super Proton Synchrotron (SPS) is a 400 GeV proton accelerator at CERN. Its main purpose is the last step in pre-acceleration of particles before injecting them into the Large Hadron Collider. Besides that, it is used for experiments directly connected to the SPS. For these xed target experiments, a steady slow extraction of the SPS beam is necessary over thousands of turns. The SPS slow extraction process makes use of the third-integer resonance in combination with an electrostatic septum. The stability of the extracted intensity and the losses at the septum are in uenced by the imperfections of the current circuit that drives the SPS quadrupoles. This report summarizes the studies that were carried out with MAD-X to simulate these imperfections.

  6. Ingenious Snake: An Adaptive Multi-Class Contours Extraction

    2018-04-01

    Active contour model (ACM) plays an important role in computer vision and medical image application. The traditional ACMs were used to extract single-class of object contours. While, simultaneous extraction of multi-class of interesting contours (i.e., various contours with closed- or open-ended) have not been solved so far. Therefore, a novel ACM model named “Ingenious Snake” is proposed to adaptively extract these interesting contours. In the first place, the ridge-points are extracted based on the local phase measurement of gradient vector flow field; the consequential ridgelines initialization are automated with high speed. Secondly, the contours’ deformation and evolvement are implemented with the ingenious snake. In the experiments, the result from initialization, deformation and evolvement are compared with the existing methods. The quantitative evaluation of the structure extraction is satisfying with respect of effectiveness and accuracy.

    SOLDE, the Isotope Separation On-Line facility, at CERN is a leading facility for the production of beams of exotic radioactive isotopes. Currently over 1000 different isotopes with half lives down to milliseconds can be extracted with beam intensities of up to 10^11 ions per second. However, due to the reactive target environment not all isotopes are extractable in sufficient amounts. In this work the extraction of short lived carbon and boron isotopes is investigated. Therefore a variety of experimental and computanional techniques have been used.

    The CERN Open Day celebrating the 50th anniversary has been a big success. More than 30000 visitors came to discover CERN's activities at 50 different sites. ATLAS showed the assemblies in hall 180, the test-beam set-up in the North Area hall and - apparently one of the biggest attractions of all - the cavern and the control room at our pit. Technical Coordination put a lot of effort into preparing the visit itinerary at Point 1 and by operating both lifts during the entire day without interruption almost 4000 visitors got the chance to see this impressive hall and the first pieces of the detector already down there. Some people even waited for more than an hour to have their turn - they remained in good spirits also thanks to videos presented to them standing in the queue and guides explaining the site. What impressed visitors most was the sheer size of our detectors: an estimated 5000 people came to see the toroids and the LAr calorimeters in halls 180 and 191, where they could watch cosmic rays i...

  5. First observations of intensity-dependent effects for transversely split beams during multiturn extraction studies at the CERN Proton Synchrotron

    Directory of Open Access Journals (Sweden)

    Simone Gilardoni

    2013-05-01

    Full Text Available During the commissioning of the CERN Proton Synchrotron multiturn extraction, tests with different beam intensities were performed in order to probe the behavior of resonance crossing in the presence of possible space charge effects. The initial beam intensity before transverse splitting was varied and the properties of the five beamlets obtained by crossing the fourth-order horizontal resonance were studied. A clear dependence of the beamlets’ parameters on the total beam intensity was found, which is the first direct observation of intensity-dependent effects for such a peculiar beam type. The experimental results are presented and discussed in detail in this paper.

  14. Multi-Paradigm and Multi-Lingual Information Extraction as Support for Medical Web Labelling Authorities

    Directory of Open Access Journals (Sweden)

    Martin Labsky

    2010-10-01

    Full Text Available Until recently, quality labelling of medical web content has been a pre-dominantly manual activity. However, the advances in automated text processing opened the way to computerised support of this activity. The core enabling technology is information extraction (IE. However, the heterogeneity of websites offering medical content imposes particular requirements on the IE techniques to be applied. In the paper we discuss these requirements and describe a multi-paradigm approach to IE addressing them. Experiments on multi-lingual data are reported. The research has been carried out within the EU MedIEQ project.

    This paper covers my work during my assignment as participant of CERN Summer Students 2015 programme. The project was aimed at refactoring and publication of the Web Application Detection tool, which was developed at CERN and priorly used internally by the Computer Security team. The range of tasks performed include initial refactoring of code, which was developed like a script rather than a Python package, through extracting components that were not specific to CERN usage, the subsequent final release of the source code on GitHub and the integration with third-party software i.e. the w3af tool. Ultimately, Web Application Detection software received positive responses, being downloaded ca. 1500 times at the time of writing this report.

    2018-05-01

    CERN optical fibre infrastructure has been growing constantly over the past decade due to ever increasing connectivity demands. The provisioning plan and fibre installation of this vast laboratory is performed by Fibre Optics and Cabling Section at Engineering Department. In this paper we analyze the procurement data for essential fibre cabling components during a five-year interval to extract the existing trends and anticipate future directions. The analysis predicts high contribution of LC connector and an increasing usage of multi-fibre connectors. It is foreseen that single-mode fibres become the main fibre type for mid and long-range installations while air blowing would be the major installation technique. Performance assessment of various connectors shows that the expanded beam ferrule is favored for emerging on-board optical interconnections thanks to its scalable density and stable return-loss.

    Launched in 2014, the Beamline for Schools (BL4S) competition allows high-school students between 16 and 18 years old to run a real experiment at CERN’s PS accelerator (see here). For two years, students and schools worldwide have risen to the challenge and taken part enthusiastically in the competition. To ensure that it runs smoothly and enjoyably, over 100 CERN people work behind the scenes. The Bulletin lifts the curtain.   Student teams from Greece and the Netherlands – the winners of CERN’s first Beamline for schools competition – came to CERN to work on their experiments using a test beam. Turning young high-school students into real physicists who use a high-energy beam, set up an experiment and deal with data acquisition and analysis, is no game. For the people at CERN, the first step is to select the best proposals from those received from schools worldwide. “In 2015, over 40 scientists helped us select the best proposa...

    In 2013, I was an Einstein Fellow with the U.S. Department of Energy and I was asked by a colleague, working in a senator's office, if I would join him in a meeting with a physicist to "translate" the science into something more understandable. That meeting turned out to be a wonderful opportunity I would never have otherwise had. During the meeting I met Michael Tuts, a physicist who was working on project ATLAS at CERN. Afterwards, I walked with him out of the Senate office building to Union Station and, in parting, he gave me his card and told me that if I were in Geneva that he could help me get a tour of CERN and the LHC.

    Quinn Slobodian from the Dahlem Humanities Center, Freie Universität Berlin will give a presentation at the CERN Library about "The Laboratory of the World Economy: Globalization Theory around 1900".   Quinn Slobodian researches the history of Germany in the world with a focus on international political economy and transnational social movements. He is really interested to hear from CERN physicists and engineers about their responses to his theories about the Global Economy at the turn of the century: We may think of globalization theory as a recent phenomenon. Yet in the decades around 1900, German-speaking economists were already trying to make sense of an entity they called “the world economy,” coining a term that would not enter other languages until after the First World War. What was the nature of the world economy? How could one visualize and represent it? What was the status of national autonomy in an era of globalized communication and trad...

    A new, rapid, green, and cost-effective magnetic solid-phase extraction of ochratoxin A from red wine samples was developed using polydopamine-coated magnetic multi-walled carbon nanotubes as the absorbent. The polydopamine-coated magnetic multi-walled carbon nanotubes were fabricated with magnetic multi-walled carbon nanotubes and dopamine by an in situ oxidative self-polymerization approach. Transmission electron microscopy, dynamic light scattering, X-ray photoelectron spectroscopy and vibrating sample magnetometry were used to characterize the absorbents. Ochratoxin A was quantified with high-performance liquid chromatography coupled with fluorescence detection, with excitation and emission wavelengths of 338 and 455 nm, respectively. The conditions affecting the magnetic solid-phase extraction procedure, such as pH, extraction solution, extraction time, absorbent amount, desorption solution and desorption time were investigated to obtain the optimal extraction conditions. Under the optimized conditions, the extraction recovery was 91.8-104.5% for ochratoxin A. A linear calibration curve was obtained in the range of 0.1-2.0 ng/mL. The limit of detection was 0.07 ng/mL, and the limit of quantitation was 0.21 ng/mL. The recoveries of ochratoxin A for spiked red wine sample ranged from 95.65 to 100.65% with relative standard deviation less than 8%. The polydopamine-coated magnetic multi-walled carbon nanotubes showed a high affinity toward ochratoxin A, allowing selective extraction and quantification of ochratoxin A from complex sample matrixes. © 2017 WILEY-VCH Verlag GmbH & Co.

    CERN, the European organization for nuclear research, has just celebrated its fifty years of existence. Its first goal was to counterbalance the migration of physics scientists towards the USA by the creation of a physics laboratory gathering scientists from the different European countries. Today, the CERN's mission has changed and has overcome all the expectations of its founders. In 2008, it will become, with the LHC (Large Hadron Collider), the biggest particle accelerator in the world. The CERN employs about 3000 physicists, engineers, technicians and workers. There is also 6500 people from 80 different countries who use the CERN's facilities during the year. The CERN is controlled by 20 European member states and 6 observer countries, and 20 non-member countries participate to the programs in progress. The CERN's power comes from its international and cosmopolitan spirit. The whole most famous physicists of the world can work together for the progress of science and for a better understanding of matter, of its interactions and of our universe. Two Nobel prices of physics come from the CERN: C. Rubbia and S. Van der Meer in 1983 for the discovery of W{sup +}, W{sup -} and Z{sub 0} bosons, and G. Charpak for the development of particle detectors. One can foresee that the LHC will allow new scientific achievements, like for instance, during experiments for the quest of the famous Higgs boson. It is important also to mention that the CERN has been at the origin of several technological innovations in all technical and engineering domains in the framework of its fundamental physics researches.

    Dan T. Abell

    2003-06-01

    Full Text Available Tracking simulations remain the essential tool for evaluating how multipolar imperfections in ring magnets restrict the domain of stable phase-space motion. In the Large Hadron Collider (LHC at CERN, particles circulate at the injection energy, when multipole errors are most significant, for more than 10^{7} turns, but systematic tracking studies are limited to a small fraction of this total time—even on modern computers. A considerable speedup is expected by replacing element-by-element tracking with the use of a symplectified one-turn map. We have applied this method to the realistic LHC lattice, version 6, and report here our results for various map orders, with special emphasis on precision and speed.

    2002-01-01

    The library is launching a 'sharing resources@CERN' campaign, aiming to increase the library's utility by including the thousands of books bought by individual groups at CERN. This will improve sharing of information among CERN staff and users. Until now many people were unaware that copies of the same book (or standard, or journal) are often held not only by the library but by different divisions. (Here Eduardo Aldaz, from the PS division, and Isabel Bejar, from the ST division, read their divisional copies of the same book.) The idea behind the library's new sharing resources@CERN' initiative is not at all to collect the books in individual collections at the CERN library, but simply to register them in the Library database. Those not belonging to the library will in principle be unavailable for loan, but should be able to be consulted by anybody at CERN who is interested. "When you need a book urgently and it is not available in the library,' said PS Division engineer Eduardo Aldaz Carroll, it is a sham...

    2009-08-01

    Full Text Available Proton beams were successfully steered through the entire ring of the CERN Large Hadron Collider (LHC on September the 10th of 2008. A reasonable lifetime was achieved for the counterclockwise beam, namely beam 2, after the radiofrequency capture of the particle bunch was established. This provided the unique opportunity of acquiring turn-by-turn betatron oscillations for a maximum of 90 turns right at injection. Transverse coupling was not corrected and chromaticity was estimated to be large. Despite this largely constrained scenario, reliable optics measurements have been accomplished. These measurements together with the application of new algorithms for the reconstruction of optics errors have led to the identification of a dominant error source.

    Peters, AJ; Adde, G

    2015-01-01

    EOS is an open source distributed disk storage system in production since 2011 at CERN. Development focus has been on low-latency analysis use cases for LHC(1) and non- LHC experiments and life-cycle management using JBOD(2) hardware for multi PB storage installations. The EOS design implies a split of hot and cold storage and introduced a change of the traditional HSM(3) functionality based workflows at CERN.The 2015 deployment brings storage at CERN to a new scale and foresees to breach 100 PB of disk storage in a distributed environment using tens of thousands of (heterogeneous) hard drives. EOS has brought to CERN major improvements compared to past storage solutions by allowing quick changes in the quality of service of the storage pools. This allows the data centre to quickly meet the changing performance and reliability requirements of the LHC experiments with minimal data movements and dynamic reconfiguration. For example, the software stack has met the specific needs of the dual computing centre set-...

    NA61/SHINE (SPS Heavy Ion and Neutrino Experiment) is a multi-purpose experimental facility to study hadron production in hadron-proton, hadron-nucleus and nucleus-nucleus collisions at the CERN Super Proton Synchrotron. It recorded the first physics data with hadron beams in 2009 and with ion beams (secondary 7Be beams) in 2011. NA61/SHINE has greatly profited from the long development of the CERN proton and ion sources and the accelerator chain as well as the H2 beamline of the CERN North Area. The latter has recently been modified to also serve as a fragment separator as needed to produce the Be beams for NA61/SHINE.

    The Booster Ring (BRing), which is the key part of HIAF (High Intensity heavy ion Accelerator Facility) complex at IMP (Institute of Modern Physics, Chinese Academy of Sciences), can provide uranium (A / q = 7) beam with a wide extraction energy range of 200-800 MeV/u. To fulfill a flexible beam extraction for multi-purpose experiments, both fast and slow extraction systems will be accommodated in the BRing. The fast extraction system is used for extracting short bunched beam horizontally in single-turn. The slow extraction system is used to provide quasi-continuous beam by the third order resonance and RF-knockout scheme. To achieve a compact structure, the two extraction systems are designed to share the same extraction channel. The general design of the fast and slow extraction systems and simulation results are discussed in this paper.

    Dewit, Bertrand; Dockx, Kristof

    CERN MEDICIS (Medical Isotopes Collected form ISOLDE) is a new facility at CERN, with the aim to extract and collect a large range of radioactive isotopes for research and development in medical applications. The ISOLDE (Isotope Separation On-Line Device) facility receives 1.4 GeV protons from the Proton Synchrotron Booster (PSB) where they impinge a target. However, about 85% of them transverse the target without interacting. By placing the MEDICIS target behind the ISOLDE target, a second life is given to these protons. The nuclear interactions inside the target result in a large variety of isotopes. After the irradiation stage, the target is transported to the MEDICIS facility where the off-line extraction is carried out and the radioactive isotope of interest is collected. The facility includes an experimental hall where employees will be working, even during a batch collection. Since we will be dealing with high activities in the target and the collection point it is of vital importance to evaluate the f...

    In a virtualized environment, contextualization is the process of configuring a VM instance for the needs of various deployment use cases. Contextualization in CernVM can be done by passing a handwritten context to the user data field of cloud APIs, when running CernVM on the cloud, or by using CernVM web interface when running the VM locally. CernVM Online is a publicly accessible web interface that unifies these two procedures. A user is able to define, store and share CernVM contexts using CernVM Online and then apply them either in a cloud by using CernVM Cloud Gateway or on a local VM with the single-step pairing mechanism. CernVM Cloud Gateway is a distributed system that provides a single interface to use multiple and different clouds (by location or type, private or public). Cloud gateway has been so far integrated with OpenNebula, CloudStack and EC2 tools interfaces. A user, with access to a number of clouds, can run CernVM cloud agents that will communicate with these clouds using their interfaces, and then use one single interface to deploy and scale CernVM clusters. CernVM clusters are defined in CernVM Online and consist of a set of CernVM instances that are contextualized and can communicate with each other.

    2014-01-01

    CERN, currently the largest organization in the world for particle physics, was founded in 1954. Originally located in Meyrin, at the outskirts of the city of Geneva in Switzerland, it has with time extended into neighboring France. The Theoretical Study Division of CERN, however, was created already in 1952, i.e., before the official inauguration of CERN. It was situated in Copenhagen. Christian Møller [1] was appointed (part-time) as the Director and there were two full time senior staff members, Gunnar Källén and Ben R. Mottelson. While constructing buildings and accelerators were in progress, an international conference was organized by CERN in the city of Geneva. This “CERN Symposium on High Energy Accelerators and Pion Physics”, 11–23 June 1956, attracted about 250 participants from outside CERN, among them at least 18 Nobel Laureates or future Laureates. Unfortunately, the participants from CERN are not listed in the Proceedings [2]. The conference focused on measuring devices such as bubbl...

    The aim of the project was to perform the processing required for automatically get a PDF/A version of the CERN Library documentation. For this, it is necessary to extract as much metadata as possible from the sources files, inject the required data into the original source files creating new ones ready for being compiled with all related dependencies. Besides, I’ve proposed the creation of a HTML version consistent with the PDF and navigable for easy access, I’ve been trying to perform some Natural Language Processing for extracting metadata, I’ve proposed the injection of the cern library documentation into the HTML version of the long writeups where it is referenced (for instance, when a CERN Library function is referenced in a sample code) Finally, I’ve designed and implemented a Graphical User Interface in order to simplify the process for the user.

  7. A Multi-stage Method to Extract Road from High Resolution Satellite Image

    International Nuclear Information System (INIS)

    Zhijian, Huang; Zhang, Jinfang; Xu, Fanjiang

    2014-01-01

    Extracting road information from high-resolution satellite images is complex and hardly achieves by exploiting only one or two modules. This paper presents a multi-stage method, consisting of automatic information extraction and semi-automatic post-processing. The Multi-scale Enhancement algorithm enlarges the contrast of human-made structures with the background. The Statistical Region Merging segments images into regions, whose skeletons are extracted and pruned according to geometry shape information. Setting the start and the end skeleton points, the shortest skeleton path is constructed as a road centre line. The Bidirectional Adaptive Smoothing technique smoothens the road centre line and adjusts it to right position. With the smoothed line and its average width, a Buffer algorithm reconstructs the road region easily. Seen from the last results, the proposed method eliminates redundant non-road regions, repairs incomplete occlusions, jumps over complete occlusions, and reserves accurate road centre lines and neat road regions. During the whole process, only a few interactions are needed

    2004-01-01

    Art students inspired by CERN will be returning to show their work 9 to 16 October in Building 500, outside the Auditorium. Seventeen art students from around Europe visited CERN last January for a week of introductions to particle physics and astrophysics, and discussions with CERN scientists about their projects. A CERN scientist "adopted"each artist so they could ask questions during and after the visit. Now the seeds planted during their visit have come to fruition in a show using many media and exploring varied concepts, such as how people experience the online world, the sheer scale of CERN's equipment, and the abstractness of the entities scientists are looking for. "The work is so varied, people are going to love some pieces and detest others," says Andrew Charalambous, the project coordinator from University College London who is also curating the exhibition. "It's contemporary modern art, and that's sometimes difficult to take in." For more information on this thought-provoking show, see: htt...

    Jakob, H; Jones, R; Jensen, L

    2003-01-01

    A new acquisition system has been developed to allow the measurement of the individual intensity of each bunch in a 40MHz bunch train. Such a system will be used for the measurement of LHC type beams after extraction from the CERN-PS right through to the dump lines of the CERN-LHC. The method is based on integrating the analogue signal supplied by a Fast Beam Current Transformer at a frequency of 40MHz. This has been made possible with the use of a fast integration ASIC developed by the University of Clermont-Ferrand, France, for the LHC-b pre-shower detector. The output of the integrator is digitised using a 12-bit ADC and fed into a Digital Acquisition Board (DAB) that was originally developed by TRIUMF, Canada, for use in the LHC orbit system. A full system set-up was commissioned during 2002 in the CERN-SPS, and following its success will now be extended in 2003 to cover the PS to SPS transfer lines and the new TT40 LHC extraction channel.

    A portable gamma and beta radiation survey meter capable of operating in a strong magnetic field is the most recent subject of a CERN patent application. Developed by members of the HSE Unit, the new instrument may find applications not only in research laboratories but also in hospitals where radioactivity is managed in the presence of magnetic fields.   The new instrument consists of two parts: an active probe and a counting unit. Inside the probe, a scintillating crystal sends its signal to a photo detection module, which in turn is connected to the electronics. The counting unit is a portable box to be fixed on the operator’s waist. Tested in a magnetic field up to 1 Tesla, this innovative radiation survey meter has an operating range of a fraction of µSv/h to 1 mSv/h for the ambient dose equivalent rate, and 45 keV – 1.3 MeV for photon energy, with a fast response. “The instrument is the result of a collaboration between CERN and the Milan Politecnico ...

Capitalism: A Love Story examines the impact of corporate dominance on the everyday lives of Americans. The film moves from Middle America, to the halls of power in Washington, to the global financial epicenter in Manhattan. With both humour and outrage, it explores the question: What is the price that America pays for its love of capitalism? Families pay the price with their jobs, their homes and their savings. Moore goes into the homes of ordinary people whose lives have been turned upside down; and he goes looking for explanations in Washington, DC and elsewhere. What he finds are the all-too-familiar symptoms of a love affair gone astray: lies, abuse, betrayal...and 14,000 jobs being lost every day.

    2015-01-01

    Based on the interfacial ligand exchange model and the law of conservation of mass, the multi-stage enantioselective liquid–liquid extraction model has been established to analyze and discuss on multi-stage centrifugal fractional extraction process of 4-nitrobenzene glycine (PGL) enantiomers. The influence of phase ratio, extractant concentra-tion, and PF6−concentration on the concentrations of enantiomers in the extract and raffinate was investigated by experiment and simulation. A good agreement between model and experiment was obtained. On this basis, the influence of many parameters such as location of stage, concentration levels, extractant excess, and number of stages on the symmetric separation performance was simulated. The optimal location of feed stage is the middle of fractional extraction equipment. The feed flow must satisfy a restricted relationship on flow ratios and the liquid throughout of centrifugal device. For desired purity specification, the required flow ratios decrease with extractant concentration and increase with PF6−concentration. When the number of stages is 18 stages at extractant excess of 1.0 or 14 stages at extractant excess of 2.0, the eeeq (equal enantiomeric excess) can reach to 99%.

    The fabrication of Linac4 is progressing at CERN with the goal of making a 160 MeV H- beam available to the LHC injection chain as from 2015. In the Linac4 the first stage of beam acceleration, after its extraction from the ion source, is provided by a Radiofrequency Quadrupole accelerator (RFQ), operating at the RF frequency of 352.2 MHz and which accelerates the ion beam to the energy of 3 MeV. The RFQ, made of three modules, one meter each, is of the four-vane kind, has been designed in the frame of a collaboration between CERN and CEA and has been completely machined and assembled at CERN. The paper describes the assembly of the RFQ structure and reports the results of RF low power measurements, in order to achieve the required accelerating field flatness within 1% of the nominal field profile.

    The CERN accelerator Logging Service currently holds more than 90 terabytes of data online, and processes approximately 450 gigabytes per day, via hundreds of data loading processes and data extraction requests. This service is mission-critical for day-to-day operations, especially with respect to the tracking of live data from the LHC beam and equipment. In order to effectively manage any service, the service provider’s goals should include knowing how the underlying systems are being used, in terms of: “Who is doing what, from where, using which applications and methods, and how long each action takes”. Armed with such information, it is then possible to: analyse and tune system performance over time; plan for scalability ahead of time; assess the impact of maintenance operations and infrastructure upgrades; diagnose past, on-going, or re-occurring problems. The Logging Service is based on Oracle DBMS and Application Servers, and Java technology, and is comprised of several layered and multi-tiered s...

  13. Evaluation of a feature extraction framework for FPGA firmware generation during a beam-test at CERN-SPS for the CBM-TRD experiment

    Energy Technology Data Exchange (ETDEWEB)

    Garcia Chavez, Cruz de Jesus; Munoz Castillo, Carlos Enrique; Kebschull, Udo [Infrastructure and Computer Systems in Data Processing (IRI), Goethe University, Frankfurt am Main (Germany); Collaboration: CBM-Collaboration

    2016-07-01

    A feature extraction framework has been developed to allow easy FPGA firmware generation for specific feature extraction algorithms in order to find and extract regions of interest within time-based signals. This framework allows the instantiation of multiple well-known feature extraction algorithms such as center of gravity, time over threshold and cluster finder, just to mention a few of them. A graphical user interface has also been built on top of the framework to provide a user-friendly way to visualize the data-flow architecture across processing stages. The FPGA platform constraints are automatically set up by the framework itself. This feature reduces the need of low-level hardware configuration knowledge that would normally be provided by the user, centering the attention in setting up the processing algorithms for the given task more than in writing hardware description code. During November 2015, a beam-test was performed at the CERN-SPS hall. The presented framework was used to generate a firmware for the SysCore3 FPGA development board used to readout two TRD detectors by means of the SPADIC 1.0 front-end chip. The framework architecture, design methodology, as well as the achieved results during the mentioned beam-test are presented.

    Consolidating phonebooks at CERN We have had many phonebooks in the past, Xwho (now decommissioned), the NICE phonebook on Windows PCs, and more recently the web site people.cern.ch. However, diversity doesn’t always equate to improved efficiency or quality. So in order to reduce the maintenance effort and to improve the user experience, we have consolidated these various phonebooks into a single web application: phonebook.cern.ch Motivations for change The NICE Phonebook was introduced in the year 2000 when Windows 95 was the major desktop platform. Since then, a lot has changed not only in technology and the desktop landscape but also in the variety of devices used to access the data (notably smartphones and tablets). Updating the NICE phonebook is slow. Once the master database is modified it can take up to two days for the data to propagate to the application. Thus, we are now planning the retirement of the NICE phonebook application. The new Phonebook.cern.ch The new phonebook.cern.ch...

  16. Apprenticeship at CERN

    CERN Multimedia

    Staff Association

    2016-01-01

    In 1961, based on the finding that the evolution of the labour market created a growing need for qualified staff, a first agreement between the Republic and Canton of Geneva and CERN was signed. One of the objectives of this agreement was the vocational training of young electronics and physics laboratory technicians. CERN, an important stakeholder in the local economy, highlighted with this agreement its willingness to participate in the local social and economic development. The first apprentice arrived at CERN in 1965. In 1971, the apprenticeship centre was created; it now hosts over twenty apprentices in total and welcomes about six new apprentices each year. These apprenticeships are for young people aged between 15 and 21 years, coming from one of the CERN Member States, and having completed their mandatory education, e.g. 11th grade in Switzerland or 3ème in France. The training is divided between working time at CERN and one or two days per week at school (CFPT in Geneva for electronics or ...

  1. Parallelism at Cern: real-time and off-line applications in the GP-MIMD2 project

    International Nuclear Information System (INIS)

    Calafiura, P.

    1997-01-01

    A wide range of general purpose high-energy physics applications, ranging from Monte Carlo simulation to data acquisition, from interactive data analysis to on-line filtering, have been ported, or developed, and run in parallel on IBM SP-2 and Meiko CS-2 CERN large multi-processor machines. The ESPRIT project GP-MIMD2 has been a catalyst for the interest in parallel computing at CERN. The project provided the 128 processor Meiko CS-2 system that is now succesfully integrated in the CERN computing environment. The CERN experiment NA48 was involved in the GP-MIMD2 project since the beginning. NA48 physicists run, as part of their day-to-day work, simulation and analysis programs parallelized using the message passing interface MPI. The CS-2 is also a vital component of the experiment data acquisition system and will be used to calibrate in real-time the 13000 channels liquid krypton calorimeter. (orig.)

  4. NEWS: A trip to CERN

    Science.gov (United States)

    Ellison, A. D.

    2000-07-01

    Two years ago John Kinchin and myself were lucky enough to attend the Goldsmith's particle physics course. As well as many interesting lectures and activities, this course included a visit to CERN. To most physics teachers CERN is Mecca, a hallowed place where gods manipulate and manufacture matter. The experience of being there was even better. Alison Wright was an enthusiastic and very knowledgeable host who ensured the visit went smoothly and we all learned a lot. While we were there, John and I discussed the possibility of bringing a party of A-level students to see real physics in action. In February of this year we managed it. 33 students from two schools, Boston Grammar School and Northampton School for Boys, and four staff left England and caught the 2 am ferry to France. Many hours and a few `short cuts' later we arrived at our hotel in St Genis, not far from CERN. The first day was spent sight-seeing in Lausanne and Geneva. The Olympic museum in Lausanne is well worth a visit. Unfortunately, the famous fountain in Geneva was turned off, but then you can't have everything. The following morning we turned up at CERN late due to the coach's brakes being iced up! We were met once again by Alison Wright who forgave us and introduced the visit by giving an excellent talk on CERN, its background and its reason for existing. At this point we met another member of our Goldsmith's course and his students so we joined forces once again. We then piled back into the coach to re-cross the border and visit ALEPH. ALEPH is a monster of a detector 150 m below ground. We divided into four groups, each with a very able and knowledgeable guide, and toured the site. The size and scale of the detector are awesome and the students were suitably impressed. We repeated the speed of sound experiment of two years ago at the bottom of a 150 m concrete shaft (320 m s-1), posed for a group photo in front of the detector (figure 1) and returned to the main site for lunch in

    AWAKE, an Advanced Wakefield Experiment is launched at CERN to verify the proton driven plasma wakefield acceleration concept. Proton bunches at 400 GeV/c will be extracted from the CERN SPS and sent along a 750 m long proton line to a plasma cell, a Rubidium vapour source, where the proton beam drives wakefields reaching accelerating gradients of several gigavolts per meter. A high power laser pulse will copropagate within the proton bunch creating the plasma by ionizing the (initially) neutral gas. An electron beam will be injected into the plasma cell to probe the accelerating wakefield. The AWAKE experiment will be installed in the CNGS facility. First proton beam to the plasma cell is expected by end 2016. The installation planning and the baseline parameters of the experiment are shown. The design of the experimental area and the integration of the new beam-lines as well as the experimental equipment are presented. The needed modifications of the infrastructure in the facility and a few challenges are h...

    2007-01-01

    The construction of the Large Hadron Collider at CERN is in its final phase, and commissioning with beam is scheduled to begin before the end of 2007. It is now time to prepare for increasing as much as possible the performance of this unique instrument to maximize the benefits for physics. An essential part of the proposed luminosity upgrade plan is the replacement of the CERN PS and its injectors by a 50 GeV proton synchrotron (PS2) and a 4 GeV superconducting linac (SPL). The design of the SPL has recently been updated and the optimization of its high-energy part will continue until ~2010. For the foreseen luminosity upgrade of the LHC a low-power version of the SPL (LP-SPL) is under study, which can be upgraded to a multi-megawatt machine providing beam to high-power proton users such as neutrino facilities and/or radio-active beam facilities. The construction start of the low-energy normal conducting SPL front-end, the 160 MeV "Linac4", is scheduled for January 2008, with the goal of being operational as...

    Otto, R

    2007-01-01

    Nearly every large organization uses a tool to broadcast messages and information across the internal campus (messages like alerts announcing interruption in services or just information about upcoming events). These tools typically allow administrators (operators) to send "targeted" messages which are sent only to specific groups of users or computers, e/g only those located in a specified building or connected to a particular computing service. CERN has a long history of such tools: CERNVMS€™s SPM_quotMESSAGE command, Zephyr and the most recent the NICE Alerter based on the NNTP protocol. The NICE Alerter used on all Windows-based computers had to be phased out as a consequence of phasing out NNTP at CERN. The new solution to broadcast information messages on the CERN campus continues to provide the service based on cross-platform technologies, hence minimizing custom developments and relying on commercial software as much as possible. The new system, called CERN Alerter, is based on RSS (Really Simpl...

  14. Information extraction from multi-institutional radiology reports.

    Science.gov (United States)

    Hassanpour, Saeed; Langlotz, Curtis P

    2016-01-01

    The radiology report is the most important source of clinical imaging information. It documents critical information about the patient's health and the radiologist's interpretation of medical findings. It also communicates information to the referring physicians and records that information for future clinical and research use. Although efforts to structure some radiology report information through predefined templates are beginning to bear fruit, a large portion of radiology report information is entered in free text. The free text format is a major obstacle for rapid extraction and subsequent use of information by clinicians, researchers, and healthcare information systems. This difficulty is due to the ambiguity and subtlety of natural language, complexity of described images, and variations among different radiologists and healthcare organizations. As a result, radiology reports are used only once by the clinician who ordered the study and rarely are used again for research and data mining. In this work, machine learning techniques and a large multi-institutional radiology report repository are used to extract the semantics of the radiology report and overcome the barriers to the re-use of radiology report information in clinical research and other healthcare applications. We describe a machine learning system to annotate radiology reports and extract report contents according to an information model. This information model covers the majority of clinically significant contents in radiology reports and is applicable to a wide variety of radiology study types. Our automated approach uses discriminative sequence classifiers for named-entity recognition to extract and organize clinically significant terms and phrases consistent with the information model. We evaluated our information extraction system on 150 radiology reports from three major healthcare organizations and compared its results to a commonly used non-machine learning information extraction method.

  15. Arrhythmia Classification Based on Multi-Domain Feature Extraction for an ECG Recognition System

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available Automatic recognition of arrhythmias is particularly important in the diagnosis of heart diseases. This study presents an electrocardiogram (ECG recognition system based on multi-domain feature extraction to classify ECG beats. An improved wavelet threshold method for ECG signal pre-processing is applied to remove noise interference. A novel multi-domain feature extraction method is proposed; this method employs kernel-independent component analysis in nonlinear feature extraction and uses discrete wavelet transform to extract frequency domain features. The proposed system utilises a support vector machine classifier optimized with a genetic algorithm to recognize different types of heartbeats. An ECG acquisition experimental platform, in which ECG beats are collected as ECG data for classification, is constructed to demonstrate the effectiveness of the system in ECG beat classification. The presented system, when applied to the MIT-BIH arrhythmia database, achieves a high classification accuracy of 98.8%. Experimental results based on the ECG acquisition experimental platform show that the system obtains a satisfactory classification accuracy of 97.3% and is able to classify ECG beats efficiently for the automatic identification of cardiac arrhythmias.

  16. First ATLAS Barrel Toroid coil casing arrives at CERN

    CERN Multimedia

    2002-01-01

    The first of eight 25-metre long coil casings for the ATLAS experiment's barrel toroid magnet system arrived at CERN on Saturday 2 March by road from Heidelberg. This structure will be part of the largest superconducting toroid magnet ever made.   The first coil casing for the toroidal magnets of Atlas arrives at Building 180. This is the start of an enormous three-dimensional jigsaw puzzle. Each of the eight sets of double pancake coils will be housed inside aluminium coil casings, which in turn will be held inside a stainless steel vacuum vessel. A huge construction, the casing that arrived at CERN measures 25 metres in length and 5 metres in width. It weighs 20 tones. And this is just the beginning of the toroid jigsaw: by early April a batch of four double pancake coils, which altogether weighs 65 tones, will arrive from Ansaldo in Italy. The first vacuum vessel will also be arriving from Felguera in Spain this month. It will take about two years for all these 25 m long structures of casings, coils a...

They started well with some good passing movements, but the Scots were also playing well and began to take control towards the end of the first half. Then, following a series of poor finishing and good goalkeeping by the CERN keeper, they finally found the back of the net, and the lads in white trooped off for well-earned oranges and water, just 1-0 down at half time. The second half was again evenly matched, but while we were not making the goal chances the Scots were squandering theirs. THEN with just 10 minutes to go a sudden resurgence of energy and aggression, the CERNites made the chances which counted, and in the space 5 minutes turned the score around and were happy to hear the final whistle and celebrate a famous 2-1 victory.

    2000-01-01

    The Large Hadron Collider (LHC) and CERN Neutrino to Gran Sasso (CNGS) projects require the construction of a new fast-extraction system in the long straight section LSS4 of the Super Proton Synchrotron (SPS) at CERN. A conventional DC septum magnet will be used, in conjunction with the installation of horizontal and vertical extraction bumpers, main quadrupoles with enlarged apertures, extraction kicker magnets and additional hardware protection, instrumentation, controls and electronics. The extraction channel must be able to accept the bright LHC proton beam at 450 GeV/c, and also the high intensity, large emittance fixed target CNGS proton beam at the nominal 400 GeV/c extraction momentum. This paper describes the extraction channel to be installed in 2003, and shows how the requirements for both the LHC and CNGS project can be met.

    In its continual tour of CERN Member States, the European Committee for Future Accelerators (ECFA) visited Lisbon, Portugal, on 21-22 April, where it met at the Instituto Superiore Tecnico, a technical university with 9,000 students. Portuguese particle physics is in a particularly healthy situation, having developed considerably following Portugal's admission to CERN in 1985. With support from Brussels, scientific infrastructure has developed rapidly, although the science base has yet to attain the levels seen in larger nations. The 45-strong population of experimentalists in Portugal, including 14 PhDs, represents a 2.5-fold increase since Portugal joined CERN ten years ago and is in line with the goal stated at the time. This successful development of experimental particle physics has benefited much from physicists returning from abroad (mainly France and the UK). The direct result of the efforts of a few individuals (notably J.M. Gago), this splendid achievement provides an excellent role model for new and potential CERN Member States. At present, particle physics represents some 3 0% of all Portuguese physics publications. This very special role (and the financial support it implies) provides a visible target, but one which can be defended as it provides a catalyst for other national scientific developments. The national hub is the Laboratory for experimental high energy physics and related R&D projects (LIP), with centres in Lisbon (Head, J.M. Gago) and Coimbra (Head, A. Policarpo). LIP, with close links to two universities in Lisbon and to the University of Coimbra, has developed into a centre of expertise and training in electronics, computing and software engineering. Present LIP funding is some 2 million Swiss francs/year (70% in Lisbon and 3 0% in Coimbra), covering most of the salaries of the nonuniversity people, the remainder being supported by grants from Portuguese and European programmes.

    Israel (along with the US, Japan, Canada, the Russian Federation and India) is one of the CERN non- Member State nations targeted for substantial future participation in CERN's experimental programme, in particular for the LHC proton collider to be built in the 27-kilometre LEP tunnel and which was formally approved by CERN Council in December (January/February, page 1). In keeping with their illustrious scientific traditions, Israeli experimental physicists have collaborated in experiments at many of the world's major high energy Laboratories - Brookhaven, Fermilab and SLAC in the US, and in Europe, DESY, Hamburg, as well as CERN. However CERN, as the geographically closest major Laboratory (as well as the largest), plays a special role for Israeli scientists. At CERN, the advent of preparations in the early 1980s for the experimental programme at the LEP electron-positron collider was the signal for Israeli researchers to mount a concerted effort and contribute to one of the experiments - Opal - at a level comparable to that of major nations. This allowed Israeli teams to participate fully in the planning and construction phase of this branch of Big Science. Underlining this commitment, and to coordinate the various national agencies involved in this aspect of Big Science, in 1983 the Israel Commission for High Energy Physics (ICHEP) was formed. It is currently chaired by David Horn of Tel Aviv. The initial ICHEP/CERN contract established the official CERN/lsrael link under which, in the short-term, teams from three major research centres - the Weizmann Institute, Tel- Aviv University, and Haifa's Technion - contributed to Opal, as the flagship experiment, while providing a framework for longer-term collaboration. (At CERN, Israeli physicists also participate in the NA45 heavy ion experiment and the NA47 Spin Muon Collaboration - SMC.) Opal groups some 320 scientists from 32 research centres in eight countries, and includes a 21-strong Israeli

    The CERN Large Hadron Collider is currently being upgraded to operate at a stored beam energy of 680 MJ through the High Luminosity upgrade. The LHC performance is dependent on the functionality of beam collimation systems, essential for safe beam cleaning and machine protection. A dedicated beam experiment at the CERN High Radiation to Materials facility is created under the HRMT-23 experimental campaign. This experiment investigates the behavior of three collimation jaws having novel composite absorbers made of copper diamond, molybdenum carbide graphite, and carbon fiber carbon, experiencing accidental scenarios involving the direct beam impact on the material. Material characterization is imperative for the design, execution, and analysis of such experiments. This paper presents new data and analysis of the thermostructural characteristics of some of the absorber materials commissioned within CERN facilities. In turn, characterized elastic properties are optimized through the development and implementation of a mixed numerical-experimental optimization technique.

    Infrared Non-Destructive Testing (INDT) is known as an effective and rapid method for nondestructive inspection. It can detect a broad range of near-surface structuring flaws in metallic and composite components. Those flaws are modeled as a smooth contour centered at peaks of stored thermal energy, termed Regions of Interest (ROI). Dedicated methodologies must detect the presence of those ROIs. In this paper, we present a methodology for ROI extraction in INDT tasks. The methodology deals with the difficulties due to the non-uniform heating. The non-uniform heating affects low spatial/frequencies and hinders the detection of relevant points in the image. In this paper, a methodology for ROI extraction in INDT using multi-resolution analysis is proposed, which is robust to ROI low contrast and non-uniform heating. The former methodology includes local correlation, Gaussian scale analysis and local edge detection. In this methodology local correlation between image and Gaussian window provides interest points related to ROIs. We use a Gaussian window because thermal behavior is well modeled by Gaussian smooth contours. Also, the Gaussian scale is used to analyze details in the image using multi-resolution analysis avoiding low contrast, non-uniform heating and selection of the Gaussian window size. Finally, local edge detection is used to provide a good estimation of the boundaries in the ROI. Thus, we provide a methodology for ROI extraction based on multi-resolution analysis that is better or equal compared with the other dedicate algorithms proposed in the state of art.

    In view of the fact that the deep convolutional neural network has stronger ability of feature learning and feature expression, an exploratory research is done on feature extraction and classification for high resolution remote sensing images. Taking the Google image with 0.3 meter spatial resolution in Ludian area of Yunnan Province as an example, the image segmentation object was taken as the basic unit, and the pre-trained AlexNet deep convolution neural network model was used for feature extraction. And the spectral features, AlexNet features and GLCM texture features are combined with multi-kernel learning and SVM classifier, finally the classification results were compared and analyzed. The results show that the deep convolution neural network can extract more accurate remote sensing image features, and significantly improve the overall accuracy of classification, and provide a reference value for earthquake disaster investigation and remote sensing disaster evaluation.

    Since the beginning of 2009, due to the CERN restructuring, LabVIEW support moved from the IT to the EN department, joining the Industrial Controls and Electronics Group (ICE). LabVIEW support has been merged with the Measurement, Test and Analysis (MTA) section which, using LabVIEW, has developed most of the measurement systems to qualify the LHC magnets and components over the past 10 years. The post mortem analysis for the LHC hardware commissioning has also been fully implemented using LabVIEW, customised into a framework, called RADE, for CERN needs. The MTA section has started with a proactive approach sharing its tools and experience with the CERN LabVIEW community. Its framework (RADE) for CERN integrated application development has been made available to the users. Courses on RADE have been integrated into the standard National Instruments training program at CERN.

    2004-01-01

    CERN starting training apprentices in 1966 at the request of the Geneva authorities. The programme was consolidated with the opening of the training centre in 1971. In recent years CERN has taken on seven new technical apprentices each year (four in electronics, three in physics laboratory work), plus one or two administrative apprentices, such that there always are around 30 apprentices in total at CERN. The programme is highly regarded in Geneva by the authorities, industry, schools and young people, and contributes very positively to CERN's local image. Since the beginning 160 young people have now successfully completed their apprenticeships at CERN. Unlike some other employers, as a general rule CERN does not take on its ex-apprentices as staff; on completing their years at CERN the apprentices usually go on to higher education or are sought after by other employers.

  14. Three-dimensional multi-terminal superconductive integrated circuit inductance extraction

    International Nuclear Information System (INIS)

    2011-01-01

    Accurate inductance calculations are critical for the design of both digital and analogue superconductive integrated circuits, and three-dimensional calculations are gaining importance with the advent of inductive biasing, inductive coupling and sky plane shielding for RSFQ cells. InductEx, an extraction programme based on the three-dimensional calculation software FastHenry, was proposed earlier. InductEx uses segmentation techniques designed to accurately model the geometries of superconductive integrated circuit structures. Inductance extraction for complex multi-terminal three-dimensional structures from current distributions calculated by FastHenry is discussed. Results for both a reflection plane modelling an infinite ground plane and a finite segmented ground plane that allows inductive elements to extend over holes in the ground plane are shown. Several SQUIDs were designed for and fabricated with IPHT's 1 kA cm −2 RSFQ1D niobium process. These SQUIDs implement a number of loop structures that span different layers, include vias, inductively coupled control lines and ground plane holes. We measured the loop inductance of these SQUIDs and show how the results are used to calibrate the layer parameters in InductEx and verify the extraction accuracy. We also show that, with proper modelling, FastHenry can be fast enough to be used for the extraction of typical RSFQ cell inductances.

    As a consequence of changes in the administrative structure of TIS Division in 1996 and 1997, the Environmental Section was integrated into the TIS Technical Services and Environment Group that also looks after the non-radiation parameters in the CERN releases and environment. However, it remains the duty of the Radiation Protection Group (RP) to define the environmental programme for radiation and radioactivity, and of the leader of RP to report its results both inside and outside CERN. Part I of this Annual Report describes the results of measurements which are relevant for assessing the radiological impact of CERN's activities on the environment and the population living in the vicinity of the CERN sites. Measurements of radioactivity released into the atmosphere and into water, as well as measurements of stray radiation at or near the CERN site boundaries, are reported.

  16. Wearable Sensor-Based Human Activity Recognition Method with Multi-Features Extracted from Hilbert-Huang Transform.

    2016-12-02

    Wearable sensors-based human activity recognition introduces many useful applications and services in health care, rehabilitation training, elderly monitoring and many other areas of human interaction. Existing works in this field mainly focus on recognizing activities by using traditional features extracted from Fourier transform (FT) or wavelet transform (WT). However, these signal processing approaches are suitable for a linear signal but not for a nonlinear signal. In this paper, we investigate the characteristics of the Hilbert-Huang transform (HHT) for dealing with activity data with properties such as nonlinearity and non-stationarity. A multi-features extraction method based on HHT is then proposed to improve the effect of activity recognition. The extracted multi-features include instantaneous amplitude (IA) and instantaneous frequency (IF) by means of empirical mode decomposition (EMD), as well as instantaneous energy density (IE) and marginal spectrum (MS) derived from Hilbert spectral analysis. Experimental studies are performed to verify the proposed approach by using the PAMAP2 dataset from the University of California, Irvine for wearable sensors-based activity recognition. Moreover, the effect of combining multi-features vs. a single-feature are investigated and discussed in the scenario of a dependent subject. The experimental results show that multi-features combination can further improve the performance measures. Finally, we test the effect of multi-features combination in the scenario of an independent subject. Our experimental results show that we achieve four performance indexes: recall, precision, F-measure, and accuracy to 0.9337, 0.9417, 0.9353, and 0.9377 respectively, which are all better than the achievements of related works.

    The first diversity interaction workshop took place on 8 March. Although the choice of date was intended as a tribute to women, the real focus of the event was raising awareness about all types of diversity at CERN.   During the workshop, the participants worked in small groups to discuss diversity. The seminar was attended by 32 people, a relatively small number if one considers how many people are working on the CERN site. Does this mean that diversity is not an issue? I would rather say that, given the international and multi-faceted character of the Laboratory, diversity is taken for granted in many cases but, thanks to the seminar, I also realized that there may be issues hiding behind different types of behaviour. The discussion was very useful in raising awareness about this fact. As summarised by Anne-Sylvie Catherin, HR Head, “Diversity is certainly one of our strengths but it needs to be continually nurtured”. The workshop started with a short film showing how ...

    A condensed version is given of CERN report ''Economic utility resulting from CERN contracts'' by the same authors, which attempts to quantify the economic benefit to high technology manufacturing industries involved in CERN contracts, in relation to their sales to CERN. It covers the period 1973 to 1987 and complements an earlier study made in 1973-1975. Interviews were carried out in 166 European firms of which the majority supplied estimates of increased sales and cost savings due to CERN contracts. This ''economic utility'' totals 3107 million Swiss francs (up to the year 1987) compared to sales to CERN in 1973 to 1982 amounting to 748 million Swiss francs in 1982 prices. It is estimated that, by 1987, CERN's high technology purchases made in 1973 to 1982 will have generated economic utility amounting to about 60% of the overall cost of the organization during the same period.

    To mark International Women's Day on 8 March, the Weekly Bulletin has looked at the careers of six female physicists, engineers and administrators working at CERN. A frequent question on the lips of newcomers to CERN as they take a quick look around them is 'But where are the women?' However, while it's true that the Laboratory has never had a huge number of female personnel, a closer look reveals that there are in fact quite a few around. To mark International Women's Day, the Bulletin has interviewed six women working at CERN to find out how they see the Organization, what they do and what they think about their daily working lives. Creating a link 'Maybe because I grew up during World War II, my parents always taught me to respect people of other nationalities, religions, colour, etc., so one thing I have always appreciated about CERN is that it promotes this tolerance and understanding by giving us the great privilege of working side by side with colleagues from many cultures and walks of life.'

    CERN CRICKET CLUB   The CERN Cricket Club 2014 season has been a good one so far with the team qualifying for the Swiss Cup semi-finals, with home advantage on the Prevessin ground on Sunday, August 24th. Their opponents will only be known the day before when the final game in the Eastern Division is played.  The CERN ground hasn’t quite recovered from the Bosons&More party last year, the wet weather making it impossible to roll the ground, but the new, wider strip is a big improvement. Net practice eventually started in late July, which is probably why the results at the beginning of the season weren’t so good. As match reports are too long to be included in the weekly bulletin, the full reports and the schedule can be found under “Matches (Fixtures, results, reports)” on the Cricket Club web site at http://cern.ch/Club-Cricket/    Anyone interested in playing cricket is welcome to join us at net practice, which takes pla...

    CERN is actively making its knowledge and technology available for the benefit of society and does so through a variety of different mechanisms. Open hardware has in recent years established itself as a very effective way for CERN to make electronics designs and in particular printed circuit board layouts, accessible to anyone, while also facilitating collaboration and design re-use. It is creating an impact on many levels, from companies producing and selling products based on hardware designed at CERN, to new projects being released under the CERN Open Hardware Licence. Today the open hardware community includes large research institutes, universities, individual enthusiasts and companies. Many of the companies are actively involved in the entire process from design to production, delivering services and consultancy and even making their own products available under open licences.

    2001-01-01

    What do CERN and other scientific organizations like ESA and ESO have in common with neurosurgery and airlines? At first sight, not much. But all require sound safety management. CERN's expertise in this field was recently highlighted when two CERN engineers were invited to talk at an international conference on Quality Management and Risk Control in Neurosurgery.CERN has long been recognised as a centre of excellence in physics, and its spin-offs in fields such as medicine have been widely hailed. But increasingly, the Laboratory's expertise in the management of large international collaborations is also being recognised. Contacts between CERN and organizations like ESA and ESO, as well as with industry, bear witness to this fact. One recent example comes from Airbus Industrie, which organized a meeting in 1998 with CERN to compare notes on project management, safety, and quality assurance. Safety management is a recognised speciality in the field of project management and at CERN, TIS and the safety offici...

    For the MedAustron facility under construction in Wiener Neustadt/Austria, two electrostatic septa are built in collaboration with CERN. These septa will be used for the multi-turn injection of protons and ions, as well as for the slow extraction from the synchrotron. The power supplies are designed to combine the required precision with the capability to cycle sufficiently fast to keep up with the machine cycle. The septa are being assembled at CERN. Initial tests have been done on the remote displacement system to validate its precision and communication protocol with the MedAustron control system. Subsequently the septa are tested for vacuum performance and then HV conditioned. The construction of the septa, the requirements of the power supplies and the high voltage circuit will be described. Results of the initial laboratory tests, prior to installation in the accelerator, will be given.

  10. Wearable Sensor-Based Human Activity Recognition Method with Multi-Features Extracted from Hilbert-Huang Transform

    Directory of Open Access Journals (Sweden)

    Huile Xu

    2016-12-01

    Full Text Available Wearable sensors-based human activity recognition introduces many useful applications and services in health care, rehabilitation training, elderly monitoring and many other areas of human interaction. Existing works in this field mainly focus on recognizing activities by using traditional features extracted from Fourier transform (FT or wavelet transform (WT. However, these signal processing approaches are suitable for a linear signal but not for a nonlinear signal. In this paper, we investigate the characteristics of the Hilbert-Huang transform (HHT for dealing with activity data with properties such as nonlinearity and non-stationarity. A multi-features extraction method based on HHT is then proposed to improve the effect of activity recognition. The extracted multi-features include instantaneous amplitude (IA and instantaneous frequency (IF by means of empirical mode decomposition (EMD, as well as instantaneous energy density (IE and marginal spectrum (MS derived from Hilbert spectral analysis. Experimental studies are performed to verify the proposed approach by using the PAMAP2 dataset from the University of California, Irvine for wearable sensors-based activity recognition. Moreover, the effect of combining multi-features vs. a single-feature are investigated and discussed in the scenario of a dependent subject. The experimental results show that multi-features combination can further improve the performance measures. Finally, we test the effect of multi-features combination in the scenario of an independent subject. Our experimental results show that we achieve four performance indexes: recall, precision, F-measure, and accuracy to 0.9337, 0.9417, 0.9353, and 0.9377 respectively, which are all better than the achievements of related works.

In a previous paper a method allowing analytical estimation of the fraction of beam trapped into resonance islands as a function of the Hamiltonian parameters has been presented. Such amethod applies to one-degree of freedom models of betatronic motion. In this paper, the analysis is extended to the more realistic and challenging case of two-degree of freedom systems, in which the interplay between the horizontal and vertical motion is fully included. Numerical simulations are presented and the results are discussed in detail.

    Wang, Min; Cui, Qi; Wang, Jie; Ming, Dongping; Lv, Guonian

    2017-01-01

    In this paper, we first propose several novel concepts for object-based image analysis, which include line-based shape regularity, line density, and scale-based best feature value (SBV), based on the region-line primitive association framework (RLPAF). We then propose a raft cultivation area (RCA) extraction method for high spatial resolution (HSR) remote sensing imagery based on multi-scale feature fusion and spatial rule induction. The proposed method includes the following steps: (1) Multi-scale region primitives (segments) are obtained by image segmentation method HBC-SEG, and line primitives (straight lines) are obtained by phase-based line detection method. (2) Association relationships between regions and lines are built based on RLPAF, and then multi-scale RLPAF features are extracted and SBVs are selected. (3) Several spatial rules are designed to extract RCAs within sea waters after land and water separation. Experiments show that the proposed method can successfully extract different-shaped RCAs from HR images with good performance.

  13. A Hierarchical Feature Extraction Model for Multi-Label Mechanical Patent Classification

    Directory of Open Access Journals (Sweden)

    Jie Hu

    2018-01-01

    Full Text Available Various studies have focused on feature extraction methods for automatic patent classification in recent years. However, most of these approaches are based on the knowledge from experts in related domains. Here we propose a hierarchical feature extraction model (HFEM for multi-label mechanical patent classification, which is able to capture both local features of phrases as well as global and temporal semantics. First, a n-gram feature extractor based on convolutional neural networks (CNNs is designed to extract salient local lexical-level features. Next, a long dependency feature extraction model based on the bidirectional long–short-term memory (BiLSTM neural network model is proposed to capture sequential correlations from higher-level sequence representations. Then the HFEM algorithm and its hierarchical feature extraction architecture are detailed. We establish the training, validation and test datasets, containing 72,532, 18,133, and 2679 mechanical patent documents, respectively, and then check the performance of HFEMs. Finally, we compared the results of the proposed HFEM and three other single neural network models, namely CNN, long–short-term memory (LSTM, and BiLSTM. The experimental results indicate that our proposed HFEM outperforms the other compared models in both precision and recall.

  15. Industrial Activity at CERN

    CERN Document Server

    Kowalik, G

    2000-01-01

    The decrease in the number of CERN staff creates the need for optimization of the non-core, infrastructure-related activities. An industrial, service-orientated approach has long been considered as an appropriate way to cope with the problem of diminishing resources. This paper presents industrial and service activity issues at CERN based on the experience of the exploitation of the power network. The most important problems linked to the application of the industrial approach to the exploitation of equipment in the CERN research environment are covered. These include the interface between accelerators and electrical exploitation services, external and internal regulations, sharing of responsibility between CERN staff and external contractors, continuous modification of clients' requirements, the balance between the cost of accelerator downtime versus the cost of infrastructure upgrade. A benchmarking through a comparison with a big industrial manufacturer is followed by recommendations for possible improveme...

    2008-01-01

    The main focus of the workshop was on collimators and beam absorbers for (mainly) High Energy Hadron Accelerators, with the energy stored in the beams far above damage limit. The objective was to better understand the technological limits imposed by mechanisms related to beam impact on materials. The idea to organise this workshop came up during the High Intensity High Brightness Hadron Beams, ICFA-HB2006 in Japan [1]. The workshop was organised 3-5 September 2007 at CERN, with about 60 participants, including 20 from outside CERN. About 30 presentations were given [2]. The event was driven by the LHC challenge, with more than 360 MJoule stored in each proton beam. The entire beam or its fraction will interact with LHC collimators and beam absorbers, and with the LHC beam dump blocks. Collimators and beam absorbers are also of the interest for other labs and accelerators: - CERN: for the CNGS target, for SPS beam absorbers (extraction protection) and collimators for protecting the transfer line between SPS an...

    Full Text Available The paper discusses the use of web crawler technology. We created an application based on standard web crawler. Our application is determined for data extraction. Primarily, the application was designed to extract data using keywords from a social network Twitter. First, we created a standard crawler, which went through a predefined list of URLs and gradually download page content of each of the URLs. Page content was then parsed and important text and metadata were stored in a database. Recently, the application was modified in to the form of the multi-agent system. The system was developed in the C# language, which is used to create web applications and sites etc. Obtained data was evaluated graphically. The system was created within Indect project at the VSB-Technical University of Ostrava.

    Cutting-edge research requires a constantly high performance of the computing equipment. At the CERN Computing Centre, computers typically need to be replaced after about four years of use. However, while servers may be withdrawn from cutting-edge use, they are still good for other uses elsewhere. This week, 220 servers and 30 routers were donated to the Kwame Nkrumah University of Science and Technology (KNUST) in Ghana.   “KNUST will provide a good home for these computers. The university has also developed a plan for using them to develop scientific collaboration with CERN,” said John Ellis, a professor at King’s College London and a visiting professor in CERN’s Theory Group.  John Ellis was heavily involved in building the relationship with Ghana, which started in 2006 when a Ghanaian participated in the CERN openlab student programme.

    Brown, Alexander

    MEDICIS is a new facility at CERN ISOLDE that aims to produce radio-isotopes for medical research. Possible designs for the collection and transport system for the collection of radio-isotopes was investigated. A system using readily available equipment was devised with the the aim of keeping costs to a minimum whilst maintaining the highest safety standards. FLUKA, a Monte Carlo radiation transport code, was used to simulate the radiation from the isotopes to be collected. Of the isotopes to be collected 44Sc was found to give the largest dose by simulating the collection of all isotopes of interest to CERN’s MEDICIS facility, for medical research. The simulations helped guide the amount of shielding used in the final design. Swiss Regulations stipulating allowed activity level of individual isotopes was also considered within the body of the work.

    The connection between CERN and space is tangible this week, as former CERN Fellow and ESA astronaut Christer Fuglesang begins the second week of his mission on space shuttle flight STS-128. I had the pleasure to meet Christer back in October 2008 at an IEEE symposium in Dresden, and he asked me whether we could give him something related to CERN for his official flight kit. We thought of caps and tee-shirts, but in the end decided to give him a neutralino as a symbol of the link between particle physics and the science of the Universe. Neutralinos are theoretical particles that the LHC will be looking for, and if they exist, they’re strong candidates for the Universe’s dark matter. Christer’s neutralino is just a model, of course, escaped from the particle zoo, but what better symbol of the connectedness of science? Christer Fuglesang is not the only link CERN has with the space shuttle programme. We’ve recently learned that...

    This June, two American celebrities (and physics enthusiasts!) came to CERN. Brian Cox gave Mike Einziger (right), lead guitarist with the rock band Incubus, the star treatment in the ATLAS cavern. Jesse Dylan embraces the spirit of ATLAS! Mike Einziger, lead guitarist with the rock band Incubus, visited CERN on Friday 13 June between concerts in Finland and England. Einziger, a lifelong science enthusiast descended into the ATLAS and CMS caverns and visited the SM18 test magnet facility during his brief tour of CERN. Einziger learned about the LHC through watching online lectures from University of Manchester and ATLAS physicist Brian Cox, and was thrilled to have the chance to see the detectors in person. The musician has created an orchestral piece, inspired in part by the work being done at CERN for the LHC, which will have its debut in Los Angeles on 23 August. Just over a week earlier, Jesse Dylan, Hollywood film director a...

  4. CERN anti-fraud policy

    CERN Multimedia

    2013-01-01

    In 2011, a working group on improved fraud prevention and management was established. The group was composed of the Director of Administration and General Infrastructure, the Head of the Human Resources Department, and the Heads of the Legal Service and Internal Audit. It recommended the adoption of a global fraud prevention and management policy.   The global fraud prevention and management policy was implemented through the CERN Anti-Fraud Policy, which was endorsed by the Enlarged Directorate in May 2012 and approved by the Director-General for entry into force on 1 January 2013. The CERN Anti-Fraud Policy defines the Organization’s policy in matters of fraud.  CERN has a zero tolerance approach towards fraud, as it would compromise the accomplishment of its objectives and undermine its functioning, credibility and reputation. The policy also states CERN’s commitment to the prevention, identification and investigation of fraud. All CERN contributors have a key rol...

    CERN technology will be taking a stellar journey as the Langton Ultimate Cosmic ray Intensity Detector (LUCID) is launched into space in 2012. LUCID has been designed by students from the CERN@school programme using Timepix chips from the Medipix Collaboration at CERN.   CERN@school students present LUCID.  In today’s educational environment, a pioneering school physics programme that involves students in authentic research seems unlikely. But in the UK, the CERN@school programme is providing the resources for school students to do just that. “We develop projects which allow students to work alongside scientists and engineers before they go to university,” says Becky Parker, head of the Langton Star Centre and founder of the CERN@school programme. “Thanks to these programmes, students can make a genuine contribution to global scientific research.

    2005-01-01

    The CERN Library Information desk.At a meeting on the Wednesday before Easter, the Executive Committee endorsed a policy of open access to all the laboratory's results, as expressed in the document ‘Continuing CERN action on Open Access' (http://cds.cern.ch/record/828991/files/open-2005-006.pdf), released by its Scientific Information Policy Board (SIPB) earlier in the month. "This underlines CERN's commitment to sharing the excitement of fundamental research with as wide an audience as possible", said Guido Altarelli, current SIPB chairman. Open Access to scientific knowledge is today the goal of an increasing component of the worldwide scientific community. It is a concept, made possible by new electronic tools, which would bring enormous benefits to all readers by giving them free access to research results. CERN has implicitly supported such moves from its very beginning. Its Convention (http://cds.cern.ch/record/330625/files/cm-p00046871.pdf), adopted in 1953, requires openness, stipulating that "......

    Hundreds of developers work on many different projects at CERN – from data analysis to beam operations and administrative applications. As of this September, they will have an opportunity to meet each other at the newly established Developers@CERN Forum.   “We go to conferences elsewhere but we hardly ever meet here at CERN, where we all work on our own separate software projects,” says José Carlos Luna, a member of the IT department and one of the organisers of the first Developers@CERN Forum. Indeed, although several CERN departments have software developers working in their teams, there is no proper “community” built around them. The first Developers@CERN Forum will be held on 28 and 29 September. The event is being organised by a few developers from the IT department, together with colleagues from the GS and EN departments. Its main scope is to reach out to all the departments in an effort to bring all CERN’s software dev...

    1993-01-01

    CERN's long and distinguished neutrino tradition began in 1958 at the then new 500 MeV synchrocyclotron (SC) with the first observation of the decay of a charged pion into an electron and a neutrino. At that time, the first ideas on the special (vector/axial vector) structure of the weak interactions had been put forward by Feynman and Gell-Mann and by Marshak and Sudarshan, but the continual non-observation of that charged pion decay was holding up progress. This decay is only one part in ten thousand, and is masked by the dominant muon-neutrino channel. A special telescope was built to pick up the high energy electrons from the pion decay. In 1962 came another SC neutrino success, with the first measurement of the decay of a charged pion into a neutral one, with emission of an electron and a neutrino. Meanwhile the main thrust of CERN's neutrino effort was taking shape at the PS. By the close of 1960, CERN had decided to attack neutrino physics using several detectors - a 1m heavy liquid bubble chamber from Andre Lagarrigue's team in Paris, a CERN 1 m heavy liquid bubble chamber, and a hybrid chamber/counter from a group led by Helmut Faissner

    Multi-objective design exploration (MODE) and its application for design rule extraction are presented. MODE reveals the structure of design space from the trade-off information. The self-organizing map (SOM) is incorporated into MODE as a visual data-mining tool for design space. SOM divides the design space into clusters with specific design features. The sufficient conditions for belonging to a cluster of interest are extracted using rough set theory. The resulting MODE was applied to the multidisciplinary wing design problem, which revealed a cluster of good designs, and we extracted the design rules of such designs successfully.

  2. Beta-and gamma-turns in proteins revisited: a new set of amino acid turn-type dependent positional preferences and potentials.

    Science.gov (United States)

    Guruprasad, K; Rajkumar, S

    2000-06-01

    The number of beta-turns in a representative set of 426 protein three-dimensional crystal structures selected from the recent Protein Data Bank has nearly doubled and the number of gamma-turns in a representative set of 320 proteins has increased over seven times since the previous analysis. Beta-turns (7153) and gamma-turns (911) extracted from these proteins were used to derive a revised set of type-dependent amino acid positional preferences and potentials. Compared with previous results, the preference for proline, methionine and tryptophan has increased and the preference for glutamine, valine, glutamic acid and alanine has decreased for beta-turns. Certain new amino acid preferences were observed for both turn types and individual amino acids showed turn-type dependent positional preferences. The rationale for new amino acid preferences are discussed in the light of hydrogen bonds and other interactions involving the turns. Where main-chain hydrogen bonds of the type NH(i + 3) --> CO(i) were not observed for some beta-turns, other main-chain hydrogen bonds or solvent interactions were observed that possibly stabilize such beta-turns. A number of unexpected isolated beta-turns with proline at i + 2 position were also observed. The NH(i + 2) --> CO(i) hydrogen bond was observed for almost all gamma-turns. Nearly 20% classic gamma-turns and 43% inverse gamma-turns are isolated turns.

    Firemen from local fire brigades have been coming to CERN to learn modern fire-fighting techniques. The CERN fire brigade has some unique training equipment for two particularly dangerous fire hazards, flashover and backdraft. Flashover occurs when a room that is on fire reaches a temperature of 400 to 500°. Beyond this point, a fully developed fire breaks out. This series of photos shows recruits from the fire services of Ain (Service Départemental Incendie et Secours (SDIS)) taking part in a flashover training exercise at CERN. Photo 01: Christopher Griggs, Chief Instructor of the CERN fire brigade (seated in the centre), explains the technique of using a fire-hose during a flashover to the recruits from the Ain SDIS.

Still, Finland can be considered as a relatively young Member State in CERN, but one of the most dynamic new partners for CERN.

  7. Automatic extraction and processing of small RNAs on a multi-well/multi-channel (M&M) chip.

    Science.gov (United States)

    Zhong, Runtao; Flack, Kenneth; Zhong, Wenwan

    2012-12-07

    The study of the regulatory roles in small RNAs can be accelerated by techniques that permit simple, low-cost, and rapid extraction of small RNAs from a small number of cells. In order to ensure highly specific and sensitive detection, the extracted RNAs should be free of the background nucleic acids and present stably in a small volume. To meet these criteria, we designed a multi-well/multi-channel (M&M) chip to carry out automatic and selective isolation of small RNAs via solid-phase extraction (SPE), followed by reverse-transcription (RT) to convert them to the more stable cDNAs in a final volume of 2 μL. Droplets containing buffers for RNA binding, washing, and elution were trapped in microwells, which were connected by one channel, and suspended in mineral oil. The silica magnetic particles (SMPs) for SPE were moved along the channel from well to well, i.e. in between droplets, by a fixed magnet and a translation stage, allowing the nucleic acid fragments to bind to the SMPs, be washed, and then be eluted for RT reaction within 15 minutes. RNAs shorter than 63 nt were selectively enriched from cell lysates, with recovery comparable to that of a commercial kit. Physical separation of the droplets on our M&M chip allowed the usage of multiple channels for parallel processing of multiple samples. It also permitted smooth integration with on-chip RT-PCR, which simultaneously detected the target microRNA, mir-191, expressed in fewer than 10 cancer cells. Our results have demonstrated that the M&M chip device is a valuable and cost-saving platform for studying small RNA expression patterns in a limited number of cells with reasonable sample throughput.

  14. New spam-detection engine for CERN mailboxes

    CERN Multimedia

    The flow of spam (unsolicited e-mail) targetting CERN mailboxes is constantly increasing: 96% of the 2.5 million mails received daily at CERN consist in successfully filtered spam, but spammers get smarter and detecting spam is becoming ever more difficult. In order to address this evolution, a new spam-detection software engine will progressively be deployed starting from 15 April 2008. It will not affect how CERN users currently deal with spam: the spam configuration page, the 'CERN Spam' folder and the Outlook 'report spam' button will continue to work exactly as before.

    CERN Multimedia

    2009-01-01

    With a strong curiosity for the work of CERN, HSH Prince Albert II of Monaco visited CMS and the CERN Control Centre on 2 September. "The Prince is interested in and sensitive to what CERN is doing. Monaco is closely linked to France, which is an important member of CERN. He wishes to express his help to the scientific community in every trip. He wants to meet scientists and to be really personally involved," explained Francois Chantrait, Head of the Press Service of the Prince’s Palace. CERN Director-General Rolf Heuer welcomed the Prince of Monaco to Point 5 with a presentation about CERN before they descended 100 metres underground to see the CMS experiment. Although the detector was closed up for test runs, he was able to see its grand scale as well as look at some of the intricate sample parts exhibited by CMS Spokesperson, Jim Virdee. The Prince wrote in the CERN Visitors’ Book that he perceives a realisation of promisin...

    2008-01-01

    The data service on GSM subscriptions has been improved, allowing CERN users to access the Internet directly. A CERN GSM subscription with data option now allows you to connect to the Internet from a mobile phone or a PC equipped with a GSM modem. The previous access (CERN intranet) still exists. To get access to the new service, you will find all the information on configurations at: http://cern.ch/gprs The use of this service on the Sunrise network is charged on a flat-rate basis (no extra charge related to the volume of downloaded data). Depending on your CERN subscription type (standard or master), you can also connect to foreign GSM data networks (roaming), but this is strongly discouraged, except where absolutely necessary, due to international roaming charges.

    The article reports on achievements of various people, staff changes and position opportunities within the CERN organization and contains news updates on upcoming or past events. Over the last several years a new 'language', MULTI, has made a major hit at Fermilab. MULTI is a program that can flexibly handle interactive on-line computing from widely differing experimental CAMAC configurations. By now twothirds of the running experiments at Fermilab are using the system. It is literally true that an on-line system can be put into practical operation over a weekend. The demands of particle accelerator builders frequently stretch modern technology to the full. Recently a new possibility has emerged, using the technique of non-evaporable 'getters' - NEG. Getters are substances capable of absorbing gas molecules, so setting up a pumping action; The workshop for electron-proton physics at the proposed HERA machine will take place at the University of Wuppertal (Federal Republic of Germany) on 2-3 October. There will be reviews on the physics potential of electron-proton collisions, on the different electron-proton collider projects, on detectors and on polarization.One of CERN's annual sporting high lights is the 3.9 km relay race around the Meyrin site. This year some 40 runners lined up at the start

  19. Digital content sewed together within a library catalogue WebLib - The CERN Document Server

    Vigen, Jens

    2002-01-01

    Aggregation, harvesting, personalization techniques, portals, service provision, etc. have all become buzzwords. Most of them simply describing what librarians have been doing for hundreds of years. Prior to the Web few people outside the libraries were concerned about these issues, a situation which today it is completely turned upside down. Hopefully the new actors on the arena of knowledge management will take full advantage of all the available "savoir faire". At CERN, the European Organization for Nuclear Research, librarians and informaticians have set up a complete system, WebLib, actually based on the traditional library catalogue. Digital content is, within this framework, being integrated to the highest possible level in order to meet the strong requirements of the particle physics community. The paper gives an overview of the steps CERN has made towards the digital library from the day the laboratory conceived the World Wide Web to present.

  4. CERN Courier has a new look

    CERN Multimedia

    2011-01-01

    During more than 50 years of existence, CERN’s well-known magazine has changed several times in appearance. Now, for the first time since the 1990s, it has a new look for the new decade.   The new cover of the CERN Courier. Originally conceived as an internal newsletter, the CERN Courier first appeared in August 1959 in an edition of 8 pages with a print run of 1000. From the start it generated interest outside CERN, with its articles not only on CERN but also about particle physics around the world. The number of copies doubled in the first 6 months in response to the external demand. As CERN prepares to welcome new Member States in the coming years, it’s even more fitting that the magazine should continue to address a global readership, now totalling some 25,000 and extending throughout the many countries that have an interest in particle physics. It’s therefore important that the CERN Courier should remain appealing to this extensive audience, both visually and i...

  9. Simon van der Meer and his legacy to CERN and particle accelerators

    International Nuclear Information System (INIS)

    2012-01-01

    Simon van der Meer was a brilliant scientist and a true giant in the field of accelerators. His seminal contributions to accelerator science are essential to this day in our quest to satisfy the demands of modern particle physics. Whether we are talking of long-baseline neutrino physics or antiproton-proton physics at CERN and Fermilab, or proton-proton physics at the LHC, his techniques and inventions have been a vital and necessary part of modern-day successes. Simon van der Meer and Carlo Rubbia were the first CERN scientists to become Nobel laureates in Physics in 1984. His less well-known contributions spanned a whole range of subjects in accelerator science from magnet design to power supply design, beam measurements, slow beam extraction, sophisticated programs, and controls.

    It's getting hot in Buildings 201 and 860, over-heating even... But no reason to panic! We're talking about the superheated water boilers of CERN's two heating plants, which heat all the buildings on the Meyrin and Prévessin sites.   View of the three boilers and the control centre of the Meyrin heating plant. CERN's two heating plants each comprise three gas* boilers, with generators of 15 MW in the case of Meyrin and 5 MW in the case of Prévessin. Both inject pressurised water, superheated to 125 degrees, into several kilometres of pipes, 22 km on the Meyrin site and 5 km in Prévessin. "A single boiler is sufficient most of the time but a second kicks in automatically during very cold weather, and a third is there on stand-by," explains Christophe Martel, head of the GS Department section responsible for CERN's heating and air-conditioning systems. All of CERN's buildings have a sub-station that receives the superheated water from the boilers an...

  19. Position-aware deep multi-task learning for drug-drug interaction extraction.

    Science.gov (United States)

    Zhou, Deyu; Miao, Lei; He, Yulan

    2018-05-01

    A drug-drug interaction (DDI) is a situation in which a drug affects the activity of another drug synergistically or antagonistically when being administered together. The information of DDIs is crucial for healthcare professionals to prevent adverse drug events. Although some known DDIs can be found in purposely-built databases such as DrugBank, most information is still buried in scientific publications. Therefore, automatically extracting DDIs from biomedical texts is sorely needed. In this paper, we propose a novel position-aware deep multi-task learning approach for extracting DDIs from biomedical texts. In particular, sentences are represented as a sequence of word embeddings and position embeddings. An attention-based bidirectional long short-term memory (BiLSTM) network is used to encode each sentence. The relative position information of words with the target drugs in text is combined with the hidden states of BiLSTM to generate the position-aware attention weights. Moreover, the tasks of predicting whether or not two drugs interact with each other and further distinguishing the types of interactions are learned jointly in multi-task learning framework. The proposed approach has been evaluated on the DDIExtraction challenge 2013 corpus and the results show that with the position-aware attention only, our proposed approach outperforms the state-of-the-art method by 0.99% for binary DDI classification, and with both position-aware attention and multi-task learning, our approach achieves a micro F-score of 72.99% on interaction type identification, outperforming the state-of-the-art approach by 1.51%, which demonstrates the effectiveness of the proposed approach.

    Do you like listening to music while working? What about watching videos during leisure time? Sure this is fun. Having your colleagues participating in this is even more fun. However, this fun is usually not free. There are music and film companies who earn their living from music and videos. Thus, if you want to listen to music or watch films at CERN, make sure that you own the proper rights to do so (and you have the agreement of your supervisor to do this during working hours). Note that these rights are personal: You usually do not have the right to share this music or these videos with third parties without violating copyrights. Therefore, making copyrighted music and videos public, or sharing music and video files as well as other copyrighted material, is forbidden at CERN --- and also outside CERN.

  9. Environmental radiation monitoring on the CERN sites and in the CERN environment during 1997

    Energy Technology Data Exchange (ETDEWEB)

    Vojtyla, P; Wittekind, D

    1998-04-10

    As a consequence of changes in the administrative structure of TIS Division in 1996 and 1997, the Environmental Section was integrated into the TIS Technical Services and Environment Group that also looks after the non-radiation parameters in the CERN releases and environment. However, it remains the duty of the Radiation Protection Group to define the environmental programme for radiation and radioactivity, and to report its results both inside and outside CERN. In 1997, the environmental programme was slightly modified after discussions with the Sektion zur Ueberwachung der Radioaktivitaet (SUeR) in Fribourg. Gamma spectroscopy analyses of moss and water plants collected once per year in the rivers l'Allondon, Le Lion, Le Nant d'Avril and La Versoix were added. Moss and water plants were chosen as they are sensitive indicators of the presence of natural and man-made radioactivity in the environment. Part I of this Annual Report describes the results of measurements which are relevant for assessing the radiological impact of CERN's activities on the environment and the population living in the vicinity of the CERN sites. Measurements of radioactivity released into the atmosphere and into water, as well as measurements of stray radiation at or near the CERN site boundaries, are reported.

  12. A brief history of CERN

    International Nuclear Information System (INIS)

    Jacob, M.

    2004-01-01

    This article draws a brief history of CERN that has just celebrated its jubilee. Today 20 member states contribute to its annual budget that reached 650 million euros in 2004. In 1954 CERN was created by 12 founder states for mainly 3 reasons: 1) to achieve a research facility dedicated to particle physics able to compete with its American counterparts and that no European country could afford alone, 2) to generate with scientific research an example and a promoter for future international collaborations, and 3) to make scientists from different countries that were at war a few years before, to work together. The creation of CERN has not led to a decline of national laboratories as it was feared in the fifties. On the contrary scientific and technical tasks have been dispatched: CERN provides member states with accelerator facilities while national laboratories and universities contribute to the design and fabrication of detectors and to the analysis of experimental data. The history of CERN is marked by 2 main scientific milestones, first the discovery of weak interaction through neutral currents in 1973 and secondly the discovery of W and Z bosons in 1983. (A.C.)

  14. A novel framework for feature extraction in multi-sensor action potential sorting.

    Extracellular recordings of multi-unit neural activity have become indispensable in neuroscience research. The analysis of the recordings begins with the detection of the action potentials (APs), followed by a classification step where each AP is associated with a given neural source. A feature extraction step is required prior to classification in order to reduce the dimensionality of the data and the impact of noise, allowing source clustering algorithms to work more efficiently. In this paper, we propose a novel framework for multi-sensor AP feature extraction based on the so-called Matched Subspace Detector (MSD), which is shown to be a natural generalization of standard single-sensor algorithms. Clustering using both simulated data and real AP recordings taken in the locust antennal lobe demonstrates that the proposed approach yields features that are discriminatory and lead to promising results. Unlike existing methods, the proposed algorithm finds joint spatio-temporal feature vectors that match the dominant subspace observed in the two-dimensional data without needs for a forward propagation model and AP templates. The proposed MSD approach provides more discriminatory features for unsupervised AP sorting applications. Copyright © 2015 Elsevier B.V. All rights reserved.

    Summer is coming - and with it, a new Microcosm exhibition showcasing CERN (see here). But while the new exhibit is preparing to enchant visitors, many have been asking about the site's former content. Will it simply be out with the old and in with the new? Not as such!   The plasma ball from Microcosm is now on display at the LHCb site. As Microcosm's new content is moving in, its old content is moving up. From LHCb to IdeaSquare, former Microcosm displays and objects are being installed across the CERN site. "Microcosm featured many elements that were well suited to life outside of the exhibition," says Emma Sanders, Microcosm project leader in the EDU group. "We didn't want this popular content to go to waste, and so set out to find them new homes across CERN." The LHCb experiment has received a number of Microcosm favourites, including the Rutherford experiment, the cosmic ray display and the Thomson experiment. "We&...

For Art Basel, they created HALO, an installation that surrounds visitors with data collected by the ATLAS experiment at the LHC. HALO consists of a 10 m wide cylinder defined by vertical piano wires, within which a 4-m tall screen displays particle collisions. The data also triggers hammers that strike the vertical wires and set up vibrations to create a truly multisensory experience. More info: https://arts.cern/event/unveiling-halo-art-basel

  9. A new proton spill from CERN to Gran Sasso

    CERN Document Server

    CERN Bulletin

    2011-01-01

    Since 21 October, CERN has been sending a new type of neutrino beam to Gran Sasso. The new configuration is intended to allow the experiments to define the departure time of the neutrinos more accurately and thus check the previous results obtained using the nominal beam configuration.   The CERN Neutrino to Gran Sasso (CNGS) beam no longer operates using the standard beam time structure. Instead, a new type of proton pulse is being produced by CERN’s accelerators and sent to the graphite target to generate neutrinos. “We are now producing extremely short beam pulses,” explains Edda Gschwendtner, the physicist in charge of the CNGS secondary beam. “During a CNGS cycle we now have a LHC type bunched beam with four bunches, each about 2 ns long. Each bunch contains more than 2.5 x 1011 protons; bunches are spaced by 500 ns. In total, this makes about 1012 protons on target for each extraction from the SPS.” The CNGS beam was originally designed to m...

  10. EFQPSK Versus CERN: A Comparative Study

    Science.gov (United States)

    Borah, Deva K.; Horan, Stephen

    2001-01-01

    This report presents a comparative study on Enhanced Feher's Quadrature Phase Shift Keying (EFQPSK) and Constrained Envelope Root Nyquist (CERN) techniques. These two techniques have been developed in recent times to provide high spectral and power efficiencies under nonlinear amplifier environment. The purpose of this study is to gain insights into these techniques and to help system planners and designers with an appropriate set of guidelines for using these techniques. The comparative study presented in this report relies on effective simulation models and procedures. Therefore, a significant part of this report is devoted to understanding the mathematical and simulation models of the techniques and their set-up procedures. In particular, mathematical models of EFQPSK and CERN, effects of the sampling rate in discrete time signal representation, and modeling of nonlinear amplifiers and predistorters have been considered in detail. The results of this study show that both EFQPSK and CERN signals provide spectrally efficient communications compared to filtered conventional linear modulation techniques when a nonlinear power amplifier is used. However, there are important differences. The spectral efficiency of CERN signals, with a small amount of input backoff, is significantly better than that of EFQPSK signals if the nonlinear amplifier is an ideal clipper. However, to achieve such spectral efficiencies with a practical nonlinear amplifier, CERN processing requires a predistorter which effectively translates the amplifier's characteristics close to those of an ideal clipper. Thus, the spectral performance of CERN signals strongly depends on the predistorter. EFQPSK signals, on the other hand, do not need such predistorters since their spectra are almost unaffected by the nonlinear amplifier, Ibis report discusses several receiver structures for EFQPSK signals. It is observed that optimal receiver structures can be realized for both coded and uncoded EFQPSK

    Although raw physics data is produced at CERN, thanks to the GRID its analysis is performed in various institutes worldwide. In addition, workshops, conferences and meetings take place all over the world. The physicist community is decentralized, and CERN must continue to provide intellectual leadership. The LHC Physics Centre is the tool that will make this possible.   Until the early days of LEP, a large part of the scientific activity related to CERN’s experiments was strongly centered at the Laboratory. Few places had the infrastructure to host activities such as the working groups preparing the Yellow Reports, and the limited access to information in the pre-web era made CERN the natural place to learn what was happening in the field. “I remember the days when we, the theorists, would come to CERN just to read the most recent preprints, which were reaching CERN's Library before we could get them in our institutes”, says Michelangelo Mangano, a member of the Theo...

    Eduroam is a secure, worldwide roaming Wi-Fi access service developed for the international research and education community. It allows people from participating institutions to obtain an Internet connection when visiting other participating institutions by simply opening their laptop.   A pilot eduroam service has been available in IT for some months. Now this pilot service will be extended to most parts of the CERN site from early January. Introduction of this pilot service brings two advantages: CERN users who register with the eduroam service here at CERN will have easy and quick access to Wi-Fi services at many other academic institutions across Europe and beyond;   People visiting CERN from other eduroam institutes will be able to connect to the Wi-Fi network at CERN without waiting for a network connection request to be approved. Being a eduroam user obviously has advantages but, like many computing services, eduroam provides a way for malicious people to steal passwords...

    In a particle accelerator, several contributions can degrade the beam quality and particularly the beam transverse emittance. In this document we will describe a system used in the CERN Proton Synchrotron (PS) to cope with the injection steering errors and the transverse instabilities: the PS transverse feedback (PS TFB). As time progresses, this system is also being used for other purpose, to increase in a controlled way the beam transverse emittance and to excite the beam for the Multi-Turn-Extraction (MTE). In 2016, it has been successfully used on some operational beams to damp injection oscillations. This allowed to test the reliability of the system for its operational deployment. A piquet service is available in case of problem.

  14. MiDas: automatic extraction of a common domain of discourse in sleep medicine for multi-center data integration.

    2011-01-01

    Clinical studies often use data dictionaries with controlled sets of terms to facilitate data collection, limited interoperability and sharing at a local site. Multi-center retrospective clinical studies require that these data dictionaries, originating from individual participating centers, be harmonized in preparation for the integration of the corresponding clinical research data. Domain ontologies are often used to facilitate multi-center data integration by modeling terms from data dictionaries in a logic-based language, but interoperability among domain ontologies (using automated techniques) is an unresolved issue. Although many upper-level reference ontologies have been proposed to address this challenge, our experience in integrating multi-center sleep medicine data highlights the need for an upper level ontology that models a common set of terms at multiple-levels of abstraction, which is not covered by the existing upper-level ontologies. We introduce a methodology underpinned by a Minimal Domain of Discourse (MiDas) algorithm to automatically extract a minimal common domain of discourse (upper-domain ontology) from an existing domain ontology. Using the Multi-Modality, Multi-Resource Environment for Physiological and Clinical Research (Physio-MIMI) multi-center project in sleep medicine as a use case, we demonstrate the use of MiDas in extracting a minimal domain of discourse for sleep medicine, from Physio-MIMI's Sleep Domain Ontology (SDO). We then extend the resulting domain of discourse with terms from the data dictionary of the Sleep Heart and Health Study (SHHS) to validate MiDas. To illustrate the wider applicability of MiDas, we automatically extract the respective domains of discourse from 6 sample domain ontologies from the National Center for Biomedical Ontologies (NCBO) and the OBO Foundry.

  15. A NEW MULTI-SPECTRAL THRESHOLD NORMALIZED DIFFERENCE WATER INDEX (MST-NDWI WATER EXTRACTION METHOD – A CASE STUDY IN YANHE WATERSHED

    2018-05-01

    Full Text Available Accurate remote sensing water extraction is one of the primary tasks of watershed ecological environment study. Since the Yanhe water system has typical characteristics of a small water volume and narrow river channel, which leads to the difficulty for conventional water extraction methods such as Normalized Difference Water Index (NDWI. A new Multi-Spectral Threshold segmentation of the NDWI (MST-NDWI water extraction method is proposed to achieve the accurate water extraction in Yanhe watershed. In the MST-NDWI method, the spectral characteristics of water bodies and typical backgrounds on the Landsat/TM images have been evaluated in Yanhe watershed. The multi-spectral thresholds (TM1, TM4, TM5 based on maximum-likelihood have been utilized before NDWI water extraction to realize segmentation for a division of built-up lands and small linear rivers. With the proposed method, a water map is extracted from the Landsat/TM images in 2010 in China. An accuracy assessment is conducted to compare the proposed method with the conventional water indexes such as NDWI, Modified NDWI (MNDWI, Enhanced Water Index (EWI, and Automated Water Extraction Index (AWEI. The result shows that the MST-NDWI method generates better water extraction accuracy in Yanhe watershed and can effectively diminish the confusing background objects compared to the conventional water indexes. The MST-NDWI method integrates NDWI and Multi-Spectral Threshold segmentation algorithms, with richer valuable information and remarkable results in accurate water extraction in Yanhe watershed.

    2008-01-01

    The flow of spam (unsolicited e-mail) targetting CERN mailboxes is constantly increasing: 96% of the 2.5 million mails received daily at CERN consist in successfully filtered spam, but spammers get smarter and detecting spam is becoming ever more difficult. In order to address this evolution, a new spam-detection software engine will progressively be deployed starting from 15 April 2008. It will not affect how CERN users currently deal with spam: the spam configuration page, the ‘CERN Spam’ folder and the Outlook ‘report spam’ button will continue to work exactly as before. Because spam detection is based on probabilities, some legitimate messages can sometimes be incorrectly detected as spam. We invite all users of CERN mailboxes to regularly check their ‘CERN spam’ folder for such messages. To prevent incorrect filtering of legitimate messages, it is possible to set up a whitelist (list of trusted e-mail addresses that bypass the spam filter) and adjust the spa...

    Preclinical in vivo imaging requires precise and reproducible delineation of brain structures. Manual segmentation is time consuming and operator dependent. Automated segmentation as usually performed via single atlas registration fails to account for anatomo-physiological variability. We present, evaluate, and make available a multi-atlas approach for automatically segmenting rat brain MRI and extracting PET activies. High-resolution 7T 2DT2 MR images of 12 Sprague-Dawley rat brains were manually segmented into 27-VOI label volumes using detailed protocols. Automated methods were developed with 7/12 atlas datasets, i.e. the MRIs and their associated label volumes. MRIs were registered to a common space, where an MRI template and a maximum probability atlas were created. Three automated methods were tested: 1/registering individual MRIs to the template, and using a single atlas (SA), 2/using the maximum probability atlas (MP), and 3/registering the MRIs from the multi-atlas dataset to an individual MRI, propagating the label volumes and fusing them in individual MRI space (propagation & fusion, PF). Evaluation was performed on the five remaining rats which additionally underwent [18F]FDG PET. Automated and manual segmentations were compared for morphometric performance (assessed by comparing volume bias and Dice overlap index) and functional performance (evaluated by comparing extracted PET measures). Only the SA method showed volume bias. Dice indices were significantly different between methods (PF>MP>SA). PET regional measures were more accurate with multi-atlas methods than with SA method. Multi-atlas methods outperform SA for automated anatomical brain segmentation and PET measure's extraction. They perform comparably to manual segmentation for FDG-PET quantification. Multi-atlas methods are suitable for rapid reproducible VOI analyses.

  4. An improved feature extraction algorithm based on KAZE for multi-spectral image

    Multi-spectral image contains abundant spectral information, which is widely used in all fields like resource exploration, meteorological observation and modern military. Image preprocessing, such as image feature extraction and matching, is indispensable while dealing with multi-spectral remote sensing image. Although the feature matching algorithm based on linear scale such as SIFT and SURF performs strong on robustness, the local accuracy cannot be guaranteed. Therefore, this paper proposes an improved KAZE algorithm, which is based on nonlinear scale, to raise the number of feature and to enhance the matching rate by using the adjusted-cosine vector. The experiment result shows that the number of feature and the matching rate of the improved KAZE are remarkably than the original KAZE algorithm.

    CERN has a longstanding tradition of pursuing fundamental physics on extreme low and high energy scales. The present physics knowledge is successfully described by the Standard Model and the General Relativity. In the anti-matter regime many predictions of this established theory still remain experimentally unverified and one of the most fundamental open problems in physics concerns the question of asymmetry between particles: why is the observable and visible universe apparently composed almost entirely of matter and not of anti-matter? There is a huge interest in the very compelling scientiic case for anti-hydrogen and low energy anti-proton physics, here to name especially the Workshop on New Opportunities in the Physics Landscape at CERN which was convened in May 2009 by the CERN Directorate and culminated in the decision for the final approval of the construction of the Extra Low ENergy Antiproton (ELENA) ring by the Research Board in June 2011.
