  1. Experience in public goods experiments

    Conte, Anna; Levati, M. Vittoria; Montinari, Natalia

    2014-01-01

    We use information on students' past participation in economic experiments, as stored in our database, to analyze whether behavior in public goods games is affected by experience (i.e., previous participation in social dilemma-type experiments) and history (i.e., participation in experiments of a different class than the social dilemma). We have three main results. First, at the aggregate level, the amount subjects contribute and expect others to contribute decrease with experience. Second, a...

  2. Examining experience

    Lakeman, G. J. T.

    2012-01-01

    I think visual experiences are intentional. And I think that different philosophical views about visual experience may be understood in terms of what they say about the intentionality of visual experience. In this thesis, I evaluate different views of experience and experiential intentionality by examining connections between experiential intentionality and further phenomenological, doxastic, epistemic and content-fixing features present in cases of perception and hallucinat...

  5. TRIO experiment

    The TRIO experiment is a test of in-situ tritium recovery and heat transfer performance of a miniaturized solid breeder blanket assembly. The assembly (capsule) was monitored for temperature and neutron flux profiles during irradiation and a sweep gas flowed through the capsule to an anaytical train wherein the amounts of tritium in its various chemical forms were determined. The capsule was designed to operate at different temperatures and sweep gas conditions. At the end of the experiment the amount of tritium retained in the solid was at a concentration of less than 0.1 wppM. More than 99.9% of tritium generated during the experiment was successfully recovered. The results of the experiment showed that the tritium inventories at the beginning and at the end of the experiment follow a relationship which appears to be characteristic of intragranular diffusion

    The design experiment is an experimental research method that aims to help design and further develop new (policy) instruments. For the development of a set of guidelines for the facilitation of citizens’ initiatives by local governments, we are experimenting with this method. It offers good opportunities for modeling interventions by testing their instrumental validity –the usefulness for the intended practical purposes. At the same time design experiments are also useful ...

  7. Simulated experiments

    A cybernetic model has been developed to elucidate some of the main principles of the growth regulation system in the epidermis of the hairless mouse. A number of actual and theoretical biological experiments have been simulated on the model. These included simulating the cell kinetics as measured by pulse labelling with tritiated thymidine and by continuous labelling with tritiated thymidine. Other simulated experiments included steady state, wear and tear, painting with a carcinogen, heredity and heredity and tumour. Numerous diagrams illustrate the results of these simulated experiments. (JIW)

  12. The Experiment

    Mariana Nicoara, Floare

    2016-04-01

    My name is Nicoara Floarea and I am teacher at Secondary School Calatele and I teach students from preparatory class and the second grade . They are six-eight years old. In my activity, for introducing scientific concepts to my students, I use various and active methods or traditional methods including experiments. The experiment stimulates students' curiosity, their creativity, the understanding and knowledge taught accessibility. I propose you two such experiments: The life cycle of the plants (long-term experiment, with rigorous observation time):We use beans, wheat or other; They are grown in pots and on the cotton soaked with water,keeping under students' observation protecting them ( just soak them regularly) and we waiting the plants rise. For discussions and comments of plant embryo development we use the plants which rose on the cotton soaked with water plants at the end of the first week. Last school year we had in the pot climbing beans which in May made pods. They were not too great but our experiment was a success. The students could deduce that there will develop those big beans which after drying will be planted again. The influence of light on plants (average duration experiment with the necessary observation time): We use two pots in which plants are of the same type (two geraniums), one of them is situated so as to get direct sunlight and other plant we put in a closed box. Although we wet both plants after a week we see that the plant that benefited from sunlight has turned strain in direct sunlight, developing normally in return the plant out of the box I have yellowed leaves, photosynthesis does not She has occurred . Students will understand the vital role of the Sun in plants' life, both in the classroom and in nature. The experiment is a method of teaching students extremely pleasant, with a remarkable percentage of acquiring more knowledge.

  13. Pixel Experiments

    Petersen, Kjell Yngve; Søndergaard, Karin; Augustesen, Christina

    2015-01-01

    Pixel Experiments The term pixel is traditionally defined as any of the minute elements that together constitute a larger context or image. A pixel has its own form and is the smallest unit seen within a larger structure. In working with the potentials of LED technology in architectural lighting...... design it became relevant to investigate the use of LEDs as the physical equivalent of a pixel as a design approach. In this book our interest has been in identifying how the qualities of LEDs can be used in lighting applications. With experiences in the planning and implementation of architectural...... lighting design in practice, one quickly experiences and realises that there are untapped potentials in the attributes of LED technology. In this research, speculative studies have been made working with the attributes of LEDs in architectural contexts, with the ambition to ascertain new strategies for...

  14. Channeling experiment

    Channeling of water flow and tracer transport in real fractures in a granite body at Stripa have been investigated experimentally. The experimental site was located 360 m below the ground level. Two kinds of experiments were performed. In the single hole experiments, 20 cm diameter holes were drilled about 2.5 m into the rock in the plane of the fracture. Specially designed packers were used to inject water into the fracture in 5 cm intervals all along the fracture trace in the hole. The variation of the injection flowrates along the fracture were used to determine the transmissivity variations in the fracture plane. Detailed photographs were taken from inside the hole and the visual fracture aperture was compared with the injection flowrates in the same locations. Geostatistical methods were used to evaluate the results. Five holes were measured in great detail. In addition 7 holes were drilled and scanned by simpler packer systems. A double hole experiment was performed where two parallel holes were drilled in the same fracture plane at nearly 2 m distance. Pressure pulse tests were made between the holes in both directions. Tracers were injected in 5 locations in one hole and monitored for in many locations in the other hole. The single hole experiment and the double hole experiment show that most of the fracture planes are tight but that there are open sections which form connected channels over distances of at least 2 meters. It was also found in the double hole experiment that the investigated fracture was intersected by at least one fracture between the two holes which diverted a large amount of the injected tracers to several distant locations at the tunnel wall.

  15. Neutrino experiments

    After participating in a several experiments near the reactor at Bugey, at distances from 15 to 100 m from the reactor the laboratory joined a collaboration for search of effect of neutrino oscillations at longer distances (1 km) from the neutrinos' point of origin. The zone covered by this experiment raises a particular interest because the results of several underground experiments on the atmospheric neutrinos indicated that oscillation could appear in this zone. The Chooz collaboration, reported here, joined three American universities (Philadelphia, New Mexico and Irvine), two Italian universities (Pisa and Trieste), the Kurchatov Institute in Moscow and two French laboratories (the LAPP in Annecy and the College de France). The first data have been recorded during the autumn of 1996 prior to the commissioning of the reactors (2 x 4200 MWth), to measure the background noise. The detector is a target of 6 t liquid scintillator doped with Gd, sunk in 120 t non-doped liquid scintillator separated by thin transparent wall. The target is viewed by 192 photomultipliers. The scintillator liquids are carried up to the detector and then to the exterior tanks by a tunnel of 200 m length and a height gradient of 15 m. The fragility of the detector imposes a simultaneous filling of its components, with an accuracy of the order of 1 cm. A 200 MHz sampling system of the photomultiplier pulses signing the neutrino interaction was developed in order to obtain simultaneously information on the pulse-height, timing and shape. This experiment could serve as a prototype for heavier experiments conceived in US, in Russia at Rovno and Krasnoyarsk, and in France, at 15 km from the Perry reactor, at 500 m underground. Still more ambitious is the Japan project at Kamioka, at 160 m distance from a nuclear reactor. The experiment at Perry will push the electron neutrino upper mass estimates down to 0.01 eV

In this paper, recent obtained physics results from commissioning data, refurbishment of detector and future step of experiment are presented.

  20. Russian experience

    Soviet research in terrestrial decontamination appears to have paralleled that of the US in many respects. However, the probability exists that long-term evaluations of decontamination techniques (over 10 to 20 years) have been carried out at one nuclear accident site (a marked divergence from US experience). The area of aquatic decontamination seems to offer the most intriguing possibilities for new information acquisition from the USSR; at this point only its potential importance can be speculated upon

  1. Shielding experiments

    Shielding mock-up experiments for Prototype Fast Breeder Reactor (PFBR) and Advanced Heavy Water Reactor (AHWR) are carried out in shielding corner facility of APSARA reactor, to assess the overall accuracy of the codes and nuclear data used in reactor shield design. As APSARA is a swimming pool-type thermal reactor, for fast reactor experiments, typical fast reactor shielding facility was created by using uranium assemblies as spectrum converter. The flux was also enhanced by replacing water by air. Experiments have been carried out to study neutron attenuation through typical fast reactor radial and axial bulk shielding materials such as steel, sodium, graphite, borated graphite and boron carbide. A large number of reaction rates, sensitive to different regions of the neutron energy spectrum, were measured using foil activation and Solid State Nuclear Track Detector (SSNTD) techniques. These experimental results were analysed using computational tools normally used in design calculations, viz., discrete ordinate transport codes with multigroup cross section sets. Comparison of measured reaction rates with calculations provided suitable bias factors for parameters relevant to shield design, such as sodium activation, fast neutron fluence, fission equivalent fluxes etc. The measured neutron spectrum on the incident face of shield model compares well with the calculated fast reactor blanket leakage neutron spectrum. The comparison of calculated reaction rates within shield model indicate that the calculations suffer from considerable uncertainties, in shield models with boron carbide/borated graphite. For AHWR shielding experiments, no spectrum converter was used as it is also a thermal reactor. Radiation streaming studies through penetrations/ducts of various shapes and sizes relevant to AHWR shielding were carried out. (author)

  2. Thomson Experiment

    This experiment, conducted by JJ Thomson in 1897, established the existence of the electron. Thomson won the Nobel physics prize for this work in 1906. A beam of electrons crosses the chamber emitting blue light. Adding an electric field (E) or a magnetic field (B) exerts a force on the moving electrons.Use switch E to turn on the electric field in the chamber. Then, by turning knob B, you can increase the current in the coils, generating a magnetic field. By balancing the electric and magnetic fields, Thomson was able to keep the electron beam level and deduce the ratio of the electron's charge to its mass.

  3. QUBIC Experiment

    Stolpovskiy, Mikhail

    2016-01-01

    QUBIC is a ground-based experiment, currently under construction, that uses the novel bolometric interferometry technology. It is dedicated to measure the primordial B-modes of CMB. As a bolometric interferometer, QUBIC has high sensitivity and good systematics control. Dust contamination is controlled by operating with two bands -- 150 and 220 GHz. There are two possible sites for QUBIC: either Concordia station in Antarctic or in the Argentinian Puna desert. It is planned to see the first light in 2018-2019.

  4. TRISTAN experiment

    Any successor to PETRA and PEP colliders was expected to extend the energy range to the region where the weak interaction effect becomes sizable in annihilation process. The aim was to reach the level, at which the all round study of the standard model can be performed in a clean system of e+e- collision. Also it was aimed to explore the energy region where top quark pair production is likely. Considering the available site for accelerator construction and the expected size of the electroweak interference effect, the target energy was set at 60 GeV at the lowest. TRISTAN-1 experiment is a big initial step in the long range physics program. The laboratory established the plan to move on to TRISTAN-2 (B Factory) project. The TRISTAN accelerator including the main storage ring, the time sequence of storage ring operation, three experimental groups of AMY, TOPAZ and VENUS, and so on are explained. The experiments on basic annihilation process, the search for new particles, the electroweak interaction, QCD studies and so on are reported. The optimum TRISTAN ring was estimated as 3 km in diameter, but the largest possible size in the site was 1/3 of that. Hard decision was made to equip the ring with unusually many accelerating RF cavities and to apply superconducting technology. (K.I.)

  5. Rutherford Experiment

    This experiment, carried out by Ernest Rutherford in 1910, revolutionised understanding of the structure of matter, showing that almost all the mass of an atom is concentrated in a very small, positively charged nucleus. Alpha particles emitted at bombard a thin gold foil. A detector records the number of alpha particles crossing the foil per second. The number is displayed on the counter and updated every minute. Alpha particles are helium nuclei, they consist of 2 protons and 2 neutrons. Rotate the central knob to change the angle between the foil and the detector. The number of alpha particles detected depends on the angle. Most of the alpha particles travel straight through the foil because the gold atoms are mainly empty space. However some hit the atomic nucleus and are deflected.

  6. Experiment POSEIDON

    An experimental program called Pool Scrubbing Effect On Iodine Decontamination (POSEIDON), was initiated at PSI in 1987 to provide a data base for gaseous iodine scrubbing in water pools. Elemental iodine and nitrogen as the carrier gas are bubbled through an orifice in a water pool. This paper reports that the test facility is composed of a 5 meter height, 1 m in diameter tank, iodine vapor preparation facility, inlet sampling system, bubble generator, outlet sampling system. The facility is designed to perform experiments at a water temperature from 20 to 60 degrees C, 1 to 4 m submergence. Various orifices, 0.5 to 12 mm in diameter, are used to generate very small to large spherical cap bubbles. Iodine concentrations at the inlet and outlet of the test section are determined by taking grab samples of the nitrogen gas and iodine vapor mixture in pre-evacuated gas bottles. The samples are then analyzed using the Total-X-Ray Fluorescence Technique (TXRF) which is developed at PSI. Lowest detection limit of this technique is 0.08 μg iodine in a litre of gas sample. The results of the tests indicated that the scrubbing process mainly is governed by the submergence level and the bubble hydrodynamics. This paper presents a description of the experimental facility and the test results

  7. Clustering experiments

    Wang, Zhengwei; Tan, Ken; Di, Zengru; Roehner, Bertrand M

    2011-01-01

    It is well known that bees cluster together in cold weather, in the process of swarming (when the ``old'' queen leaves with part of the colony) or absconding (when the queen leaves with all the colony) and in defense against intruders such as wasps or hornets. In this paper we describe a fairly different clustering process which occurs at any temperature and independently of any special stimulus or circumstance. As a matter of fact, this process is about four times faster at 28 degree Celsius than at 15 degrees. Because of its simplicity and low level of ``noise'' we think that this phenomenon can provide a means for exploring the strength of inter-individual attraction between bees or other living organisms. For instance, and at first sight fairly surprisingly, our observations showed that this attraction does also exist between bees belonging to different colonies. As this study is aimed at providing a comparative perspective, we also describe a similar clustering experiment for red fire ants.

    2007-01-01

    The goal of the Grid is to provide a coherent access to distributed computing resources. All LHC experiments are using several Grid infrastructures and a variety of the middleware flavors. Due to the complexity and heterogeinity of a distributed system the monitoring represents a challenging task. Independently of the underlying platform , the experiments need to ave a complete and uniform picture of their activities on the Grid ideally seen by the users as a single powerful computing resource. Overall operation of the infrastructure used by experiments is defined both by the quality of the Grid and the quality of the tools and services developed/used by the experiments. Correspondingly the required monitoring information should combine both Grid-related and experiment/application specific data. On the other hand, users of the LHC experiments have various roles and need different levels of details regarding monitoring data. The paper will focus on the Grid monitoring from the experiment/user perspectives with...

  2. Product Experience Is Seductive.

    Hoch, Stephen J

    2002-01-01

    Product experience seduces consumers into believing that they learn more than is actually so. There are several reasons for this. First, experience is more engaging than most attempts at education, both more vivid and intentional, and consequently more memorable. Second, experience is viewed as nonpartisan, devoid of the didacticism of formal education and the self-serving interests of advertisers. Third, much of experience is ambiguous, but not recognized as such. Experience supports a pseud...

Two experiments have directly and indirectly tested Popper's hypothesis, but they seem to give contrasting results. The equations governing these two experiments and Popper's thought experiment will be derived from basic quantum principles. The experimental constants will be inputted and it will show that the two experiments agree with each other and with quantum theory.

    Overgaard, Morten

    2011-01-01

    Blindsight is classically defined as residual visual capacity, e.g., to detect and identify visual stimuli, in the total absence of perceptual awareness following lesions to V1. However, whereas most experiments have investigated what blindsight patients can and cannot do, the literature contains...... several, often contradictory, remarks about remaining visual experience. This review examines closer these remarks as well as experiments that directly approach the nature of possibly spared visual experiences in blindsight....

    In luxury brand management, experiences are essential. However, most of what we know about designing customer experiences originates from work developed with and/or for mass brands. Luxury brands are conceptually different and require a specific approach to brand management. Using a grounded theory approach, we present a framework consisting of seven principles to design luxury experience. Our research suggests that to create a true luxury experience brands should go beyond traditional framew...

  11. The Experiment Factory: Standardizing Behavioral Experiments.

    Sochat, Vanessa V; Eisenberg, Ian W; Enkavi, A Zeynep; Li, Jamie; Bissett, Patrick G; Poldrack, Russell A

    2016-01-01

    The administration of behavioral and experimental paradigms for psychology research is hindered by lack of a coordinated effort to develop and deploy standardized paradigms. While several frameworks (Mason and Suri, 2011; McDonnell et al., 2012; de Leeuw, 2015; Lange et al., 2015) have provided infrastructure and methods for individual research groups to develop paradigms, missing is a coordinated effort to develop paradigms linked with a system to easily deploy them. This disorganization leads to redundancy in development, divergent implementations of conceptually identical tasks, disorganized and error-prone code lacking documentation, and difficulty in replication. The ongoing reproducibility crisis in psychology and neuroscience research (Baker, 2015; Open Science Collaboration, 2015) highlights the urgency of this challenge: reproducible research in behavioral psychology is conditional on deployment of equivalent experiments. A large, accessible repository of experiments for researchers to develop collaboratively is most efficiently accomplished through an open source framework. Here we present the Experiment Factory, an open source framework for the development and deployment of web-based experiments. The modular infrastructure includes experiments, virtual machines for local or cloud deployment, and an application to drive these components and provide developers with functions and tools for further extension. We release this infrastructure with a deployment (http://www.expfactory.org) that researchers are currently using to run a set of over 80 standardized web-based experiments on Amazon Mechanical Turk.

  12. The Experiment Factory: Standardizing Behavioral Experiments

    Sochat, Vanessa V.; Eisenberg, Ian W.; Enkavi, A. Zeynep; Li, Jamie; Bissett, Patrick G.; Poldrack, Russell A.

    2016-01-01

    The administration of behavioral and experimental paradigms for psychology research is hindered by lack of a coordinated effort to develop and deploy standardized paradigms. While several frameworks (Mason and Suri, 2011; McDonnell et al., 2012; de Leeuw, 2015; Lange et al., 2015) have provided infrastructure and methods for individual research groups to develop paradigms, missing is a coordinated effort to develop paradigms linked with a system to easily deploy them. This disorganization leads to redundancy in development, divergent implementations of conceptually identical tasks, disorganized and error-prone code lacking documentation, and difficulty in replication. The ongoing reproducibility crisis in psychology and neuroscience research (Baker, 2015; Open Science Collaboration, 2015) highlights the urgency of this challenge: reproducible research in behavioral psychology is conditional on deployment of equivalent experiments. A large, accessible repository of experiments for researchers to develop collaboratively is most efficiently accomplished through an open source framework. Here we present the Experiment Factory, an open source framework for the development and deployment of web-based experiments. The modular infrastructure includes experiments, virtual machines for local or cloud deployment, and an application to drive these components and provide developers with functions and tools for further extension. We release this infrastructure with a deployment (http://www.expfactory.org) that researchers are currently using to run a set of over 80 standardized web-based experiments on Amazon Mechanical Turk. By providing open source tools for both deployment and development, this novel infrastructure holds promise to bring reproducibility to the administration of experiments, and accelerate scientific progress by providing a shared community resource of psychological paradigms.

  18. Experiments on superconductors

    The book requires no prior knowledge in theoretical physics. It presents fundamental knowledge on superconductors in a clear manner, using experiments ot describe superconductor phenomena so even laymen can understand. The best-known experiment is the suspended magnet experiment based on the Meissner effect. Experiments show how the transition temperature, the critical current, the critical magnetic field strength, the suspension effect and the critical frequency of a HF current can be identified. It is shown how strong magnetic fields can be produced b multifilament HT superconducting wires. The handling of liquid nitrogen and the effects of cryogenic temperatures on electronic components are demonstrated by experiments. Suppliers of materials required for the experiments are listed as well. (orig.)

  19. Experiment, right or wrong

    Franklin, Allan

    2008-01-01

    In Experiment, Right or Wrong, Allan Franklin continues his investigation of the history and philosophy of experiment presented in his previous book, The Neglect of Experiment. In this new study, Franklin considers the fallibility and corrigibility of experimental results and presents detailed histories of two such episodes: 1) the experiment and the development of the theory of weak interactions from Fermi's theory in 1934 to the V-A theory of 1957 and 2) atomic parity violation experiments and the Weinberg-Salam unified theory of electroweak interactions of the 1970s and 1980s. In these episodes Franklin demonstrates not only that experimental results can be wrong, but also that theoretical calculations and the comparison between experiment and theory can also be incorrect. In the second episode, Franklin contrasts his view of an "evidence model" of science in which questions of theory choice, confirmation, and refutation are decided on the basis of reliable experimental evidence, with that proposed by the ...

  20. Future reactor experiments

    The non-zero neutrino mixing angle θ13 has been discovered and precisely measured by the current generation short-baseline reactor neutrino experiments. It opens the gate of measuring the leptonic CP-violating phase and enables the neutrino mass ordering. The JUNO and RENO-50 proposals aim at resolving the neutrino mass ordering using reactors. The experiment design, physics sensitivity, technical challenges as well as the progresses of those two proposed experiments are reviewed in this paper

  2. [Near death experiences].

    Rubia Vila, Francisco José

    2012-01-01

    Near Death Experiences are those accounted by people who after being clinically dead return to life spontaneously or after reanimation. These experiences have been used traditionally to support the belief in the existence of the soul and of life after death. However, today neuroscience tries to explain these experiences from the scientific point of view, i.e. explaining them based on their brain substrates. Their resemblance to mystic experiences and to altered states of consciousness seems to indicate that they may be produced by hyperactivity of limbic structures caused by anoxia or hypercapnia.

  4. Exploring sensory neuroscience through experience and experiment.

    Wyttenbach, Robert A

    2012-01-01

    Many phenomena that we take for granted are illusions - color and motion on a TV or computer monitor, for example, or the impression of space in a stereo music recording. Even the stable image that we perceive when looking directly at the real world is illusory. One of the important lessons from sensory neuroscience is that our perception of the world is constructed rather than received. Sensory illusions effectively capture student interest, but how do you then move on to substantive discussion of neuroscience? This article illustrates several illusions, attempts to connect them to neuroscience, and shows how students can explore and experiment with them. Even when (as is often the case) there is no agreed-upon mechanistic explanation for an illusion, students can form hypotheses and test them by manipulating stimuli and measuring their effects. In effect, students can experiment with illusions using themselves as subjects. PMID:23493966

    In this paper, we argue that music cognition involves the use of acoustic and auditory codes to evoke a variety of conscious experiences. The variety of domains that are encompassed by music is so diverse that it is unclear whether a single domain of structure or experience is defining. Music is best understood as a form of communication in which…

  18. Experience as Excursion

    Svabo, Connie; Shanks, Michael

    2014-01-01

    A central value of what may be termed Experience Design is its aspiration to shift focus from the logic of singular design fields to the interrelations and interactions that take place in situations where people are simultaneously engaged with multiple designs. Experience Design can allow...... researchers and practitioners to travel – making it possible to follow experiences as they are enacted across and between places, modes of transportation, mobile mediation and assemblages of things. Drawing on the nomadic metaphysics of philosopher Michel Serres, the journeying, shifting and propagating...... qualities of experience are highlighted as part of a suggestion that design may indeed relate as much to metaphysics as to mechanics, materials science, and the psychology of the consumer and user. An Experience Design is sketched out as the choreography of temporary and shifting engagements across...

  19. Undergraduate reactor control experiment

    A sequence of reactor and related experiments has been a central element of a senior-level laboratory course at Pennsylvania State University (Penn State) for more than 20 yr. A new experiment has been developed where the students program and operate a computer controller that manipulates the speed of a secondary control rod to regulate TRIGA reactor power. Elementary feedback control theory is introduced to explain the experiment, which emphasizes the nonlinear aspect of reactor control where power level changes are equivalent to a change in control loop gain. Digital control of nuclear reactors has become more visible at Penn State with the replacement of the original analog-based TRIGA reactor control console with a modern computer-based digital control console. Several TRIGA reactor dynamics experiments, which comprise half of the three-credit laboratory course, lead to the control experiment finale: (a) digital simulation, (b) control rod calibration, (c) reactor pulsing, (d) reactivity oscillator, and (e) reactor noise

  20. Cryogenics for LHC experiments

    2001-01-01

    Cryogenic systems will be used by LHC experiments to maximize their performance. Institutes around the world are collaborating with CERN in the construction of these very low temperature systems. The cryogenic test facility in hall 180 for ATLAS magnets. High Energy Physics experiments have frequently adopted cryogenic versions of their apparatus to achieve optimal performance, and those for the LHC will be no exception. The two largest experiments for CERN's new flagship accelerator, ATLAS and CMS, will both use large superconducting magnets operated at 4.5 Kelvin - almost 270 degrees below the freezing point of water. ATLAS also includes calorimeters filled with liquid argon at 87 Kelvin. For the magnets, the choice of a cryogenic version was dictated by a combination economy and transparency to emerging particles. For the calorimeters, liquid argon was selected as the fluid best suited to the experiment's physics requirements. High Energy Physics experiments are the result of worldwide collaborations and...

  1. Molybdenum solar neutrino experiment

    The goal of the molybdenum solar neutrino experiment is to deduce the 8B solar neutrino flux, averaged over the past several million years, from the concentration of 98Tc in a deeply buried molybdenum deposit. The experiment is important to an understanding of stellar processes because it will shed light on the reason for the discrepancy between theory and observation of the chlorine solar neutrino experiment. Possible reasons for the discrepancy may lie in the properties of neutrinos (neutrino oscillations or massive neutrinos) or in deficiencies of the standard solar model. The chlorine experiment only measures the 8B neutrino flux in current times and does not address possible temporal variations in the interior of the sun, which are also not considered in the standard model. In the molybdenum experiment, we plan to measure 98Tc (4.2 Myr), also produced by 8B neutrinos, and possibly 97Tc (2.6 Myr), produced by lower energy neutrinos

  2. USML-1 Glovebox experiments

    Naumann, Robert J.

    1995-01-01

    This report covers the development of and results from three experiments that were flown in the Materials Science Glovebox on USML-1: Marangoni convection in Closed Containers (MCCC), Double Float Zone (DFZ), and Fiber Pulling in Microgravity (FPM). The Glovebox provided a convenient, low cost method for doing simple 'try and see' experiments that could test new concepts or elucidate microgravity phenomena. Since the Glovebox provided essentially one (or possibly two levels of confinement, many of the stringent verification and test requirements on the experiment apparatus could be relaxed and a streamlined test and verification plan for flight qualification could be implemented. Furthermore, the experiments were contained in their own carrying cases whose external configurations could be identified early in the integration sequence for stowage considerations while delivery of the actual experiment apparatus could be postponed until only a few months before flight. This minimized the time fluids must be contained and reduced the possibility of corrosive reactions that could ruin the experiment. In many respects, this exercise was as much about developing a simpler, cheaper way of doing crew-assisted science as it was about the actual scientific accomplishments of the individual experiments. The Marangoni Convection in Closed Containers experiment was designed to study the effects of a void space in a simulated Bridgman crystal growth configuration and to determine if surface tension driven convective flows that may result from thermal gradients along any free surfaces could affect the solidification process. The Fiber Pulling in Microgravity experiment sought to separate the role of gravity drainage from capillarity effects in the break-up of slender cylindrical liquid columns. The Stability of a Double Float Zone experiment explored the feasibility of a quasi-containerless process in which a solidifying material is suspended by two liquid bridges of its own melt.

  3. Simulation - modeling - experiment; Simulation - modelisation - experience

    NONE

    2004-07-01

    After two workshops held in 2001 on the same topics, and in order to make a status of the advances in the domain of simulation and measurements, the main goals proposed for this workshop are: the presentation of the state-of-the-art of tools, methods and experiments in the domains of interest of the Gedepeon research group, the exchange of information about the possibilities of use of computer codes and facilities, about the understanding of physical and chemical phenomena, and about development and experiment needs. This document gathers 18 presentations (slides) among the 19 given at this workshop and dealing with: the deterministic and stochastic codes in reactor physics (Rimpault G.); MURE: an evolution code coupled with MCNP (Meplan O.); neutronic calculation of future reactors at EdF (Lecarpentier D.); advance status of the MCNP/TRIO-U neutronic/thermal-hydraulics coupling (Nuttin A.); the FLICA4/TRIPOLI4 thermal-hydraulics/neutronics coupling (Aniel S.); methods of disturbances and sensitivity analysis of nuclear data in reactor physics, application to VENUS-2 experimental reactor (Bidaud A.); modeling for the reliability improvement of an ADS accelerator (Biarotte J.L.); residual gas compensation of the space charge of intense beams (Ben Ismail A.); experimental determination and numerical modeling of phase equilibrium diagrams of interest in nuclear applications (Gachon J.C.); modeling of irradiation effects (Barbu A.); elastic limit and irradiation damage in Fe-Cr alloys: simulation and experiment (Pontikis V.); experimental measurements of spallation residues, comparison with Monte-Carlo simulation codes (Fallot M.); the spallation target-reactor coupling (Rimpault G.); tools and data (Grouiller J.P.); models in high energy transport codes: status and perspective (Leray S.); other ways of investigation for spallation (Audoin L.); neutrons and light particles production at intermediate energies (20-200 MeV) with iron, lead and uranium targets (Le Colley F

  4. DT experiment on JET

    In November, 1991, at the JET tokamak in Abingdon, the U.K., DT plasma combustion experiment was carried out for the first time in history. The output power by nuclear fusion of 1.7 MW at maximum and the total power output of 2 MJ were attained, and it was proved that the controlled nuclear fusion accompanied by considerable power output can be carried out on the ground as a real thing. One milestone of the dream and target of nuclear fusion reactors was attained. In this paper, the results of the experiment are reported, and their meaning for the research of hereafter is considered. In the experiment this time, 0.24 g of tritium in total was used, including conditioning. The last two shots became the power output experiment of MW class nuclear fusion reaction, in which about 13% of tritium fuel ratio was estimated. The preliminary tritium experiment was divided into six phases, and was carried out for three weeks, aiming at collecting the basic data for the full scale DT experiment. The examination of the research program, the preliminary tritium experiment and the success of the PTE and the new development are described. (K.I.)

  5. Radiochemical solar neutrino experiments

    Radiochemical experiments have been crucial to solar neutrino research. Even today, they provide the only direct measurement of the rate of the proton-proton fusion reaction, p+p→d+e++νe, which generates most of the Sun's energy. We first give a little history of radiochemical solar neutrino experiments with emphasis on the gallium experiment SAGE - the only currently operating detector of this type. The combined result of all data from the Ga experiments is a capture rate of 67.6±3.7 SNU. For comparison to theory, we use the calculated flux at the Sun from a standard solar model, take into account neutrino propagation from the Sun to the Earth and the results of neutrino source experiments with Ga, and obtain 67.3-3.5+3.9 SNU. Using the data from all solar neutrino experiments we calculate an electron neutrino pp flux of φpp♁=(3.41-0.77+0.76)×1010/(cm2-s), which agrees well with the prediction from a detailed solar model of φpp♁=(3.30-0.14+0.13)×1010/(cm2-s). Four tests of the Ga experiments have been carried out with very intense reactor-produced neutrino sources and the ratio of observed to calculated rates is 0.88±0.05. One explanation for this unexpectedly low result is that the cross section for neutrino capture by the two lowest-lying excited states in 71Ge has been overestimated. We end with consideration of possible time variation in the Ga experiments and an enumeration of other possible radiochemical experiments that might have been.

  6. Drexhage's Experiment for Sound

    Langguth, Lutz; Fleury, Romain; Alò, Andrea; Koenderink, A. Femius

    2016-06-01

    Drexhage's seminal observation that spontaneous emission rates of fluorophores vary with distance from a mirror uncovered the fundamental notion that a source's environment determines radiative linewidths and shifts. Further, this observation established a powerful tool to determine fluorescence quantum yields. We present the direct analogue for sound. We demonstrate that a Chinese gong at a hard wall experiences radiative corrections to linewidth and line shift, and extract its intrinsic radiation efficiency. Beyond acoustics, our experiment opens new ideas to extend the Drexhage experiment to metamaterials, nanoantennas, and multipolar transitions.

  9. Results from neutrino experiments

    Recent (first or/and the best) results from the neutrino experiments are reviewed and their implications for the theory are discussed. The sense of the experiments is the searching for neutrino masses, mixing and interactions beyond the standard model. Present laboratory experiments give upper bounds on the masses and the mixing which are at the level of predictions of the ''electroweak see-saw''. Positive indications of nonzero lepton mixing follow from studies of the solar and atmospheric neutrinos. (author). 95 refs, 11 figs

  10. Neutrino Oscillation Experiments

    The current status and future propects for neutrino mass and oscillation experiments is summarized. An initial short summary of the direct neutrino mass measurements is given including double beta-decay and cosmological constraints. Next the current neutrino oscillations results are described for the solar, atmospheric, and LSND Δ m2 regions. This is followed by an overview of the expectations for the near-term reactor and long baseline experiments. Finally, the plans for the longer term oscillation program including the Hyper-K and LBNE experiments are described.

    This paper addresses a telecommunication payload project approved by the R.O.C. NSPO's ROCSAT-1 space program. This project will enable several innovative experiments via the low-earth-orbit satellite ROCSAT-1, including multipath fading channel characterization, ionospheric scintillation measurement, real-time voice communications, and CDMA data communications. A unified L/S-band transponder payload is proposed for conducting these experiments in an efficient way. The results of these experiments would provide the evolving mobile communication communities with fruitful information.

    Søndergaard, Morten

    identify and locate the experiments of POEX65 as acts; and to ask the questions: what constitutes those acts as experiments? and how do we possibly archive them? My purpose, then, is to define the methodologies to obtain the contours of a post-phenomenology of experimental artistic production in order to...... be able to analyse the phenomena found at POEX65. Here I will use the notion of the ‘ontological theatre’ (Pickering), which, according to Pickering, is acted out in experimental art productions. The experiment could thus be seen as an ‘agency-realism’ – as an ‘act’ of relations across the aesthetics...

  15. THERMAL DISTRIBUTION SYSTEM EXPERIMENT

    KRAJEWSKI,R.F.; ANDREWS,J.W.; WEI,G.

    1999-09-01

    A laboratory experiment has been conducted which tests for the effects of distribution system purging on system Delivery Effectiveness (DE) as defined in ASHRAE 152P. The experiment is described in its configuration, instrumentation, and data acquisition system. Data gathered in the experiment is given and discussed. The results show that purging of the distribution system alone does not offer any improvement of the system DE. Additional supporting tests were conducted regarding experimental simulations of buffer zones and bare pipe and are also discussed.

  16. Phenomenological Account of Religious Experience

    Donny Gahral Adian

    2011-08-01

    Full Text Available History of philosophy is built upon rigid discrimination between various human experiences. Human experiences are divided mainly into two major experiences: Perceptual and intelectual. Perceptual experience is deined by empiricism as an aposteriori experience of empirical sensations. Meanwhile, rationalism claims that the only acceptable experience is apriori experience of intelectual object (natural laws, mathematical equations and logical operations. There is no other experience outside those two philosophical account of experiences. All other experiences must be subsumed either within perceptual or intelectual experience.

    Rasmussen, Tove Arendt

    2014-01-01

    Experience understood as experience-based consumption is by now fairly absent from the research agenda of the different theories on sustainable consumption. On the basis of Colin Campbell’s notion of romantic ethics and emotional sentimentality in modern hedonism, I claim that sustainable...... consumption may re-enchant ordinary consumption and thereby even become a part of marketing and the experience economy. New layers of meaning are at stake and altruistic motives come into play; doing something good for someone or something, aside from oneself, is a very strong trigger of positive emotions...... convince the individual that she really does care for others and thereby provide a positive experience of feeling good – even if it takes place in the universe of consumption fantasies only....

    Experience iS an activity that arouses emotions and generates meanings based on vivid sensation and profound compreh ension.It iS emotional,meaningful,and personal,playing a key role in the course of forming and developing one'S qualities.The psychological process of experience generation consists of such links as sensing things,arousing emotions,promoting comprehension and association,generating insights and meanings,and deepening emotional responses.Undergoing things personally by means of direct sensation,taking part in activities,and living life are the most important preconditions of experience generation.Emotional influence,situational edification,and arts edification ale extemal factors that induce experience generation.

  19. Experience and Sustainable Consumption

    Rasmussen, Tove Arendt

    Experience understood as experience-based consumption is by now fairly absent from the research agenda of the different theories on sustainable consumption. On the basis of Colin Campbell’s notion of romantic ethics and emotional sentimentality in modern hedonism, I claim that sustainable...... consumption may re-enchant ordinary consumption and thereby even become a part of marketing and the experience economy. New layers of meaning are at stake and altruistic motives come into play; doing something good for someone or something, aside from oneself, is a very strong trigger of positive emotions...... convince the individual that she really does care for others and thereby provide a positive experience of feeling good – even if it takes place in the universe of consumption fantasies only....

  1. Conceptualising the audiobook experience

    Iben Have

    2012-12-01

    Full Text Available In this article we wish to introduce and discuss a theoretical framework for a possible conceptualisation of the differences between reading a printed book and listening to an audiobook. We tend to introduce similarities and differences between reading with the eyes and reading with the ears, implying that we should not discuss the audiobook experience as a remediation of the printed book experience only, but as an entirely different experience that could be conceptualised in continuation of mobile listening practises. As a methodological strategy we will emphasise the differences between the literary practices, reading with the eyes and reading with the ears. These different perspectives on reading are used to accentuate the distinct experiences, and future thorough analyses in continuation of this framework would appear much more complex and connected than in the present article.

  4. Status of RENO Experiment

    An experiment, RENO (Reactor Experiment for Neutrino Oscillation), is under construction to measure the smallest and unknown neutrino mixing angle (θ13) using anti-neutrinos emitted from the Yonggwang nuclear power plant in Korea. The experimental setup consists of two identical 16-ton Gadolinium loaded liquid scintillator detectors located near and far from the reactor array to measure the deviations from the inverse square distance law. The experiment is planned to start data-taking in early 2011. An estimated systematic uncertainty associated with the measurement is less than 0.6%. Based on three years of data, it would be sensitive to measure the neutrino mixing angle in the range of sin2(2θ13)>0.02. In this talk, the status of RENO experiment is described.

  7. User Experience Dimensions

    Lykke, Marianne; Jantzen, Christian

    2016-01-01

    The present study develops a set of 10 dimensions based on a systematic understanding of the concept of experience as a holistic psychological. Seven of these are derived from a psychological conception of what experiencing and experiences are. Three supplementary dimensions spring from the...... observation that experiences apparently have become especially valuable phenomena in Western societies. The 10 dimensions are tried out in a field study at the Center for Art and Media (ZKM) in Germany with the purpose to study their applicability in the evaluation of interactive sound archives. 29 walk......-alongs were carried out with 58 museums visitors. Our analysis showed that it was possible to identify the 10 experience dimensions in the study material. Some dimensions were expressed more frequently than others. The distribution of expressed dimensions and the content of the user comments provided a clear...

    The rotational component of the CMB polarization, the so-called B-modes, is one of the major topic for next generation CMB experiments. This signal traces the effect on the CMB due to primordial gravitational waves produced during the inflationary epoch, probing the physics of the very early universe at GUT energy scales. This is a challenge, being the expected amplitude of B-mode polarization ~ 0.1μK. In this paper we describe the BRAIN experiment, a bolometric interferometer which combines high sensitivity bolometric detectors with the excellent control of systematic effects proper of interferometers. Being a ground based experiment, we identified Dome Charlie in Antarctica as the best site for such measurements. In order to validate the goodness of the site, as well as some of the implemented technical solutions, we built a pathfinder experiment which has been successfully operated during last Antarctic summer, and we report about preliminary results obtained.

  12. Experiment-o-mania

    Drndarski, Marina

    2015-04-01

    Every 21st century student is expected to develop science literacy skills. As this is not part of Serbian national curriculum yet, we decided to introduce it with this project. Experiment-o-mania provides students to experience science in different and exciting way. It makes opportunity for personalized learning offering space and time to ask (why, where, how, what if) and to try. Therefore, we empower young people with skills of experimenting, and they love science back. They ask questions, make hypothesis, make problems and solve them, make mistakes, discuss about the results. Subsequently this raises the students' interest for school curriculum. This vision of science teaching is associated with inquiry-based learning. Experiment-o-mania is the unique and recognizable teaching methodology for the elementary school Drinka Pavlović, Belgrade, Serbia. Experiment-o-mania implies activities throughout the school year. They are held on extra class sessions, through science experiments, science projects or preparations for School's Days of science. Students learn to ask questions, make observations, classify data, communicate ideas, conduct experiments, analyse results and make conclusions. All science teachers participate in designing activities and experiments for students in Experiment-o-mania teaching method. But they are not alone. Teacher of fine arts, English teachers and others also take part. Students have their representatives in this team, too. This is a good way to blend knowledge among different school subject and popularize science in general. All the experiments are age appropriate and related to real life situations, local community, society and the world. We explore Fibonacci's arrays, saving energy, solar power, climate change, environmental problems, pollution, daily life situations in the country or worldwide. We introduce great scientists as Nikola Tesla, Milutin Milanković and sir Isaac Newton. We celebrate all relevant international days, weeks

  9. Reconstructing Experiences through Sketching

    Karapanos, Evangelos; Hassenzahl, Marc

    2009-01-01

    This paper presents iScale, a survey tool that aims at eliciting users' experiences with a product from memory. iScale employs sketching in imposing a process in the reconstruction of one's experiences. Two versions of iScale, the Constructive and the Value-Account iScale, were motivated by two distinct theories on how people reconstruct emotional experiences from memory. These two versions were tested in two separate studies. Study 1 aimed at providing qualitative insight into the use of iScale and compared its performance to that of free-hand sketching. Study 2 compared the two iScale versions to a control condition: that of reporting one's experiences without employing any form of sketching. Significant differences between iScale and the "no-sketching" tool were found. Overall, iScale resulted in a) an increase in the number of experience reports that subjects provided, b) an increase in the amount of contextual information for the reported experiences, and c) an increase in subjects' accuracy in recalling...

  10. Understanding customer experience.

    Meyer, Christopher; Schwager, Andre

    2007-02-01

    Anyone who has signed up for cell phone service, attempted to claim a rebate, or navigated a call center has probably suffered from a company's apparent indifference to what should be its first concern: the customer experiences that culminate in either satisfaction or disappointment and defection. Customer experience is the subjective response customers have to direct or indirect contact with a company. It encompasses every aspect of an offering: customer care, advertising, packaging, features, ease of use, reliability. Customer experience is shaped by customers' expectations, which largely reflect previous experiences. Few CEOs would argue against the significance of customer experience or against measuring and analyzing it. But many don't appreciate how those activities differ from CRM or just how illuminating the data can be. For instance, the majority of the companies in a recent survey believed they have been providing "superior" experiences to customers, but most customers disagreed. The authors describe a customer experience management (CEM) process that involves three kinds of monitoring: past patterns (evaluating completed transactions), present patterns (tracking current relationships), and potential patterns (conducting inquiries in the hope of unveiling future opportunities). Data are collected at or about touch points through such methods as surveys, interviews, focus groups, and online forums. Companies need to involve every function in the effort, not just a single customer-facing group. The authors go on to illustrate how a cross-functional CEM system is created. With such a system, companies can discover which customers are prospects for growth and which require immediate intervention. PMID:17345685

  11. Staged theta pinch experiments

    Two implosion heating circuits are being experimentally tested. The principal experiment in the program is the 4.5-m-long Staged Theta Pinch (STP). It uses two relatively low energy (50kJ and 100 kJ), high voltage (125 kV) capacitor banks to produce the theta pinch plasma inside the 20 cm i.d. quartz discharge tube. A lower voltage (50 kV), higher energy (750 kJ) capacitor bank is used to contain the plasma and provide a variable amount of adiabatic compression. Because the experiment produces a higher ratio of implosion heating to compressional heating than conventional theta pinches, it should be capable of producing high temperature plasmas with a much larger ratio of plasma radius to discharge tube radius than has been possible in the past. The Resonant Heating Experiment (RHX) in its initial configuration is the same as a 0.9-m-long section of the high voltage part of the STP experiment and all the plasma results here were obtained with the experiment in that configuration. Part of the implosion bank will be removed and a low inductance crowbar added to convert it to the resonant heating configuration. (U.K.)

  12. National Flood Interoperability Experiment

    2014-12-01

    The National Flood Interoperability Experiment is led by the academic community in collaboration with the National Weather Service through the new National Water Center recently opened on the Tuscaloosa campus of the University of Alabama. The experiment will also involve the partners in IWRSS (Integrated Water Resources Science and Services), which include the USGS, the Corps of Engineers and FEMA. The experiment will address the following questions: (1) How can near-real-time hydrologic forecasting at high spatial resolution, covering the nation, be carried out using the NHDPlus or next generation geofabric (e.g. hillslope, watershed scales)? (2) How can this lead to improved emergency response and community resilience? (3) How can improved an improved interoperability framework support the first two goals and lead to sustained innovation in the research to operations process? The experiment will run from September 2014 through August 2015, in two phases. The mobilization phase from September 2014 until May 2015 will assemble the components of the interoperability framework. A Summer Institute to integrate the components will be held from June to August 2015 at the National Water Center involving faculty and students from the University of Alabama and other institutions coordinated by CUAHSI. It is intended that the insight that arises from this experiment will help lay the foundation for a new national scale, high spatial resolution, near-real-time hydrologic simulation system for the United States.

  13. Operating experience feedback

    Slovenian Nuclear Safety Administration (SNSA) has developed its own system for tracking, screening and evaluating the operating experiences of the nuclear installations. The SNSA staff regularly tracks the operating experiences throughout the world and screens them on the bases of applicability for the Slovenian nuclear facilities. The operating experiences, which pass the screening, are thoroughly evaluated and also recent operational events in these facilities are taken into account. If needed, more information is gathered to evaluate the conditions of the Slovenian facilities and appropriate corrective actions are considered. The result might be the identification of the need for modification at the licensee, the need for modification of internal procedures in the SNSA or even the proposal for the modification of regulations. Information system helps everybody to track the process of evaluation and proper logging of activities. (author)

  14. Results of space experiments

    Life science research in space was started in Europe with the first Biostack experiment flown onboard Apollo 16 in 1972. Biostack was designed to investigate the biological effects of single heavy ions of cosmic radiation. Among several undertakings towards this goal, the Biostack achieved the highest precision in the determination of the spatial correlation of the observed biological response of single test organisms to the passage of single heavy ions, which is the mandatory requirement. It also provided information on the influence of additional space-flight factors, such as microgravity, on radiation effects and measurements of the spectrum of charge and energy of the cosmic radiation. The experiment was performed as an international cooperation effort. This report gives a summary of the biological data accumulated in this and the follow-on experiments of the Biostack program.

  16. Future Reactor Experiments

    He, Miao

    2013-01-01

    The measurement of the neutrino mixing angle $\\theta_{13}$ opens a gateway for the next generation experiments to measure the neutrino mass hierarchy and the leptonic CP-violating phase. Future reactor experiments will focus on mass hierarchy determination and the precision measurement of mixing parameters. Mass hierarchy can be determined from the disappearance of reactor electron antineutrinos based on the interference effect of two separated oscillation modes. Relative and absolute measurement techniques have been explored. A proposed experiment JUNO, with a 20 kton liquid scintillator detector of $3%/$$\\sqrt{E(MeV)}$ energy resolution, $\\sim$ 53 km far from reactors of $\\sim$ 36 GW total thermal power, can reach to a sensitivity of $\\Delta\\chi^{2}>16$ considering the spread of reactor cores and uncertainties of the detector response. Three of mixing parameters are expected to be measured to better than 1% precision. There are multiple detector options for JUNO under investigation. The technical challenges...

  18. Qualitative experiments in psychology

    Wagoner, Brady

    2015-01-01

    In this article, I explore the meaning of experiments in early twentieth century psychology, focusing on the qualitative experimental methodology of psychologist Frederic BARTLETT. I begin by contextualizing BARTLETT's experiments within the continental research tradition of his time, which...... was in a state of transition from a focus on elements (the concern of psychophysics) to a focus on wholes (the concern of Gestalt psychology). The defining feature of BARTLETT's early experiments is his holistic treatment of human responses, in which the basic unit of analysis is the active person relating...... to some material within the constraints of a social and material context. This manifests itself in a number of methodological principles that contrast with contemporary understandings of experimentation in psychology. The contrast is further explored by reviewing the history of "replications...

  19. Conditioning experiences and phobias.

    Merckelbach, H; de Ruiter, C; van den Hout, M A; Hoekstra, R

    1989-01-01

    A retrospective study was conducted to examine the extent to which phobias are associated with a conditioning pathway to fear. The Phobic Origin Questionnaire (Ost and Hugdahl, Behav. Res. Ther. 19, 439-477, 1981) was administered to a sample of 91 phobic outpatients (patients with panic disorder with agoraphobia, social phobics, simple phobics). Results show clearly that conditioning experiences occur more frequently than either vicarious or informational, learning experiences, which confirms the findings previously reported by Rimm, Janda, Lancaster, Nahl and Dittmar (Behav. Res. Ther. 15, 231-238, 1977) and by Ost and Hugdahl (1981; Behav. Res. Ther. 21, 623-631, 1983). Yet, conditioning experiences consist mainly of panic attacks in confirmed environments. The findings also suggest that a considerable number of phobias are based on a combination of different pathways to fear. PMID:2610660

  20. Double beta decay experiments

    The great sensitivity of double beta decay to neutrino mass and right handed currents has motivated many new and exciting attempts to observe this elusive nuclear phenomenon directly. Experiments in operation and other coming on line in the next one or two years are expected to result in order-of-magnitude improvements in detectable half lives for both the two-neutrino and no-neutrino modes. A brief history of double beta decay experiments is presented together with a discussion of current experimental efforts, including a gas filled time projection chamber being used to study selenium-82.

  1. STELLA Experiment: Hardware issues

    The Staged Electron Laser Acceleration (STELLA) experiment is currently being assembled and tested at the BNL Accelerator Test Facility (ATF). The existing BNL inverse free electron laser (IFEL) has been positioned upstream of the inverse Cerenkov acceleration (ICA) experiment on Beamline no. 1. This beamline also features new quadrupoles and a new spectrometer capable of a ±20% energy acceptance. A new laser beam transport system has been installed to permit accurate control of the laser phase for the laser beams sent to the IFEL and ICA devices. Detection of the microbunches are performed using a coherent transition radiation (CTR) diagnostic similar to one already demonstrated at the ATF

  2. Future of neutrino experiments

    Takaaki Kajita

    2009-01-01

    Atmospheric, solar, reactor and accelerator neutrino oscillation experiments have measured $ m_{12}^{2}$, sin2 12, $| m_{23}^{2} |$ and sin2 223. The next stage of the oscillation studies should be the observation of a finite sin2 213. If a non-zero sin2 213 is observed, the subsequent goals should be the observation of the CP violation and the determination sign of $ m_{23}^{2}$. Possible future neutrino oscillation experiments that could assess these questions are discussed.

  3. Skylab experiments on metals

    Lundquist, C. A.

    1974-01-01

    The Skylab Materials Processing Facility is described. Eight experiments on metal processing under near-zero-gravity conditions were performed in this facility.

  4. Initial Cooling Experiment (ICE)

    Photographic Service

    1978-01-01

    In 1977, in a record-time of 9 months, the magnets of the g-2 experiment were modified and used to build a proton/antiproton storage ring: the "Initial Cooling Experiment" (ICE). It served for the verification of the cooling methods to be used for the "Antiproton Project". Stochastic cooling was proven the same year, electron cooling followed later. Also, with ICE the experimental lower limit for the antiproton lifetime was raised by 9 orders of magnitude: from 2 microseconds to 32 hours. For its previous life as g-2 storage ring, see 7405430. More on ICE: 7711282, 7809081, 7908242.

  5. The Moving Flame Experiment

    Stern, Melvin E.

    2011-01-01

    When a flame is rotated around the outside bottom rim of a cylindrical pan of water initially at rest, D. Fultz has observed that the fluid acquires a net vertical component of angular momentum opposite to the rotation of the heat source. We have repeated this experiment in a cylindrical annulus in order to restrict the radial motions and have found that the same phenomenon occurs. Using a simple model based on the latter experiment we investigate the mechanism by which a fluid can acquire an...

  6. Experiments in radiochemistry

    Twelve experiments in radiochemistry, nuclear chemistry, radiation detection and radiation measurement are presented which have been tested in teaching practice. Criteria of selection were minimum apparative expenditure, preparation time, radiation exposure, and danger of incorporation or contamination. The experiments will teach students how to handle unsealed radioactive materials within a fraction of a permissible values and thus train them in radiochemical techniques of working. Theoretical, historical and topical aspects are mentioned in order to give the students some background. A detailed bibliography of relevant publications is given. (orig./HP)

    Lu, Haoqi

    2014-01-01

    Neutrinos are elementary particles in the standard model of particle physics. There are 3 flavors of neutrinos that oscillate among themselves. Their oscillation can be described by a 3$\\times$3 unitary matrix, containing three mixing angles $\\theta_{12}$, $\\theta_{23}$, $\\theta_{13}$, and one CP phase. Both $\\theta_{12}$ and $\\theta_{23}$ are known from previous experiments. $\\theta_{13}$ was unknown just two years ago. The Daya Bay experiment gave the first definitive non-zero value in 2012. An improved measurement of the oscillation amplitude $\\sin^{2}2(\\theta_{13})$ = $0.090^{+0.008}_{-0.009}$ and the first direct measurement of the $\\bar\

    The OLYMPUS experiment was designed to measure the ratio between the positron–proton and electron–proton elastic scattering cross-sections, with the goal of determining the contribution of two-photon exchange to the elastic cross-section. Two-photon exchange might resolve the discrepancy between measurements of the proton form factor ratio, μ{sub p}G{sub E}{sup p}/G{sub M}{sup p}, made using polarization techniques and those made in unpolarized experiments. OLYMPUS operated on the DORIS storage ring at DESY, alternating between 2.01 GeV electron and positron beams incident on an internal hydrogen gas target. The experiment used a toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight detectors to measure rates for elastic scattering over the polar angular range of approximately 25°–75°. Symmetric Møller/Bhabha calorimeters at 1.29° and telescopes of GEM and MWPC detectors at 12° served as luminosity monitors. A total luminosity of approximately 4.5 fb{sup −1} was collected over two running periods in 2012. This paper provides details on the accelerator, target, detectors, and operation of the experiment.

  16. Experiments on ferrimagnetism

    Ferrimagnetism undoubtedly deserves a proper place in the undergraduate laboratory on electricity and magnetism. Four student experiments on ferrimagnetism are considered: (i) the hysteresis loops and permeability of a ‘soft’ ferrite; (ii) the differential permeability versus a dc bias; (iii) the frequency dependence of the complex permeability and (iv) the electromagnetic interference suppression by ferrite chokes and beads. Two ferrite cores taken off a low-frequency choke and a power cord are used. The measurements are simple and straightforward and show the important properties of ferrites and their applications. The values of the permeability of the ferrite core determined in experiments (i)–(iii) are in reasonable agreement. The frequency dependence of the complex permeability of the ferrites is similar to that given by the manufacturers. The capability of absorbing electromagnetic waves in a definite frequency range shown in experiment (iv) demonstrates one of the principles of Stealth technology. The equipment necessary for the experiments can be found in many student laboratories. (paper)

    2007-01-01

    The Florida Footprint experiments were a series of field programs in which perfluorocarbon tracers were released in different configurations centered on a flux tower to generate a data set that can be used to test transport and dispersion models. These models are used to determine the sources of the CO{sub 2} that cause the fluxes measured at eddy covariance towers. Experiments were conducted in a managed slash pine forest, 10 km northeast of Gainesville, Florida, in 2002, 2004, and 2006 and in atmospheric conditions that ranged from well mixed, to very stable, including the transition period between convective conditions at midday to stable conditions after sun set. There were a total of 15 experiments. The characteristics of the PFTs, details of sampling and analysis methods, quality control measures, and analytical statistics including confidence limits are presented. Details of the field programs including tracer release rates, tracer source configurations, and configuration of the samplers are discussed. The result of this experiment is a high quality, well documented tracer and meteorological data set that can be used to improve and validate canopy dispersion models.

    Detail of one of the magnets on the Common Muon and Proton Apparatus for Structure and Spectroscopy (COMPASS) experiment. COMPASS studies the structure of composite particles which interact via the strong force, called hadrons. These have a complicated internal structure due to the nature of their force carriers, gluons, which can form self interacting bunches called glueballs.

  3. Self managing experiment resources

    Stagni, F.; Ubeda, M.; Tsaregorodtsev, A.; Romanovskiy, V.; Roiser, S.; Charpentier, P.; Graciani, R.

    2014-06-01

    Within this paper we present an autonomic Computing resources management system, used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG, and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware, addressed such issues. With a renewed Central Information Schema hosting all resources metadata and a Status System (Resource Status System) delivering real time information, the system controls the resources topology, independently of the resource types. The Resource Status System applies data mining techniques against all possible information sources available and assesses the status changes, that are then propagated to the topology description. Obviously, giving full control to such an automated system is not risk-free. Therefore, in order to minimise the probability of misbehavior, a battery of tests has been developed in order to certify the correctness of its assessments. We will demonstrate the performance and efficiency of such a system in terms of cost reduction and reliability.

    2013-12-15

    The OLYMPUS experiment was designed to measure the ratio between the positron-proton and electron-proton elastic scattering cross sections, with the goal of determining the contribution of two-photon exchange to the elastic cross section. Two-photon exchange might resolve the discrepancy between measurements of the proton form factor ratio, {mu}{sub p}G{sup p}{sub E}/G{sup p}{sub M}, made using polarization techniques and those made in unpolarized experiments. OLYMPUS operated on the DORIS storage ring at DESY, alternating between 2.01 GeV electron and positron beams incident on an internal hydrogen gas target. The experiment used a toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight detectors to measure rates for elastic scattering over the polar angular range of approximately 25 -75 . Symmetric Moeller/Bhabha calorimeters at 1.29 and telescopes of GEM and MWPC detectors at 12 served as luminosity monitors. A total luminosity of approximately 4.5 fb{sup -1} was collected over two running periods in 2012. This paper provides details on the accelerator, target, detectors, and operation of the experiment.

    Hydrogels are very attractive materials since they can absorb large quantities of water. They also have very interesting optical properties which can be easily shown. The experiments with hydrogel pearls related to the absorption of water, density, optical properties and influence of pH are presented in the contribution.

  8. Experiment R701

    1974-01-01

    This experiment was designed by the CERN-Aachen-MPI/Munich-Heidelberg Collaboration to study inelastic proton-proton collisions with streamer chambers. The photo shows the lower streamer chamber closely fitting around the central bicone vacuum chamber at I-7. The upper chamber, here removed, was similarly fitted (Photo Archive 7401099).

    We present a unit comprising theory, simulation and experiment for a body oscillating on a vertical spring, in which the simultaneous use of a force probe and an ultrasonic range finder enables one to explore quantitatively and understand many aspects of simple and damped harmonic motions. (Contains 14 figures.)

  11. The Mobilisatsia experience

    The hazards of long-duration manned space flight are real. In order to participate effectively in long duration orbital missions or to continue the exploration of space, the health of the astronaut must be secured. There is mounting evidence that changes in the immune response of an astronaut in short-term flights, resemble those occurring after acute stress, while the changes during long-term flights resemble those caused by chronic stress. This blunting of the immune system occurs concomitant with a relative increase in microbial contamination in the space cabin environment. Such a combination of events results in an increased probability of in-flight infectious events. Micro-organisms are subject to a genetic evolution, which may lead to the capacity to colonize new environments and to cause infections. Central players in this evolutionary process are mobile genetic elements. They help to mobilize and reorganize genes, be it within a given genome (intragenomic mobility) or between bacterial cells (intercellular mobility). Hence, the processes of genetic exchange can mobilize genetic elements between bacterial strains, and therefore play a role in determining the infectious potential. The specific confined environment and space-flight related factors (such as microgravity and cosmic radiation) may increase the frequency in which mobile genetic elements are exchanged between micro organisms. The aim of the Mobilisatsia experiment was to promote microbial gene transfer under space flight conditions during a short-term experiment conducted aboard the International Space Station (ISS). The efficiency of the gene exchange process was compared with a synchronously performed ground control experiment. An experiment was carried out with well-characterized Gram-negative reference strains and one experiment was done with Gram-positive reference strains

  12. Transformations of emotional experience.

    de Cortiñas, Lia Pistiner

    2013-06-01

    In this paper the author approaches mental pain and the problems in a psychoanalytic treatment of patients with difficulties in the psychic transformation of their emotional experiences. The author is interested in the symbolic failure related to the obstruction of development of phantasies, dreams, dream-thoughts, etc. She differentiates symbolization disturbances related to hypertrophic projective identification from a detention of these primitive communications and emotional isolation. She puts forward the conjecture that one factor in the arrest of this development is the detention of projective identifications and that, when this primitive means of communication is re-established in a container-contained relationship of mutual benefit, this initiates the development of a symbolization process that can replace the pathological 'protection'. Another hypothesis she develops is that of inaccessible caesuras that, associated with the detention of projective identification, obstruct any integrative or interactive movement. This caesura and the detention of projective identifications affect mental functions needed for dealing with mental pain. The personality is left with precarious mental equipment for transforming emotional experiences. How can a psychoanalytical process stimulate the development of creative symbolization, transforming the emotional experiences and leading towards mental growth? The author approaches the clinical problem with the metaphor of the psychic birth of emotional experience. The modulation of mental pain in a container-contained relationship is a central problem for the development of the human mind. For discovering and giving a meaning to emotional experience, the infant depends on reverie, a function necessary in order to develop an evolved consciousness capable of being aware, which is different from the rudimentary consciousness that perceives but does not understand. The development of mature mental equipment is associated with the

  13. Hydrothermal organic synthesis experiments

    Shock, Everett L.

    1992-01-01

    The serious scientific debate about spontaneous generation which raged for centuries reached a climax in the nineteenth century with the work of Spallanzani, Schwann, Tyndall, and Pasteur. These investigators demonstrated that spontaneous generation from dead organic matter does not occur. Although no aspects of these experiments addressed the issue of whether organic compounds could be synthesized abiotically, the impact of the experiments was great enough to cause many investigators to assume that life and its organic compounds were somehow fundamentally different than inorganic compounds. Meanwhile, other nineteenth-century investigators were showing that organic compounds could indeed be synthesized from inorganic compounds. In 1828 Friedrich Wohler synthesized urea in an attempt to form ammonium cyanate by heating a solution containing ammonia and cyanic acid. This experiment is generally recognized to be the first to bridge the artificial gap between organic and inorganic chemistry, but it also showed the usefulness of heat in organic synthesis. Not only does an increase in temperature enhance the rate of urea synthesis, but Walker and Hambly showed that equilibrium between urea and ammonium cyanate was attainable and reversible at 100 C. Wohler's synthesis of urea, and subsequent syntheses of organic compounds from inorganic compounds over the next several decades dealt serious blows to the 'vital force' concept which held that: (1) organic compounds owe their formation to the action of a special force in living organisms; and (2) forces which determine the behavior of inorganic compounds play no part in living systems. Nevertheless, such progress was overshadowed by Pasteur's refutation of spontaneous generation which nearly extinguished experimental investigations into the origins of life for several decades. Vitalism was dealt a deadly blow in the 1950's with Miller's famous spark-discharge experiments which were undertaken in the framework of the Oparin

  14. The gravitational wave experiment

    Since the optimum size of a gravitational wave detector is the wave length, interplanetary dimensions are needed for the mHz band of interest. Doppler tracking of Ulysses will provide the most sensitive attempt to date at the detection of gravitational waves in the low frequency band. The driving noise source is the fluctuations in the refractive index of interplanetary plasma. This dictates the timing of the experiment to be near solar opposition and sets the target accuracy for the fractional frequency change at 3.0 x 10 exp -14 for integration times of the order of 1000 sec. The instrumentation utilized by the experiment is distributed between the radio systems on the spacecraft and the seven participating ground stations of the Deep Space Network and Medicina. Preliminary analysis is available of the measurements taken during the Ulysses first opposition test.

  15. The NEMO-3 Experiment

    The NEMO-3 (Neutrino Ettore Majorana Observatory) experiment, located in the Modane Underground Laboratory, is currently searching for neutrinoless double beta decay (0νββ). The experiment has been taking data since 2003 with seven double beta isotopes and is scheduled to complete data acquisition in late 2010. Two neutrino double beta decay (2νββ) results for the main isotopes (7 kg of 100Mo and 1 kg of 82Se), new results for 150Nd, as well as results for 96Zr, 48Ca, 130Te and 116Cd are presented. NEMO-3 uses a unique technique that allows for the in situ measurement of background contamination. No evidence for neutrinoless double beta decay has been found to date. The data are also interpreted in terms of alternative models such as weak right-handed currents and Majoron emission.

  16. Stirling machine operating experience

    Ross, Brad A.; Dudenhoefer, James E.

    1991-01-01

    Numerous Stirling machines have been built and operated, but the operating experience of these machines is not well known. It is important to examine this operating experience in detail, because it largely substantiates the claim that Stirling machines are capable of reliable and lengthy lives. The amount of data that exists is impressive, considering that many of the machines that have been built are developmental machines intended to show proof of concept, and were not expected to operate for any lengthy period of time. Some Stirling machines (typically free-piston machines) achieve long life through non-contact bearings, while other Stirling machines (typically kinematic) have achieved long operating lives through regular seal and bearing replacements. In addition to engine and system testing, life testing of critical components is also considered.

  17. White Cliffs: Operating Experience

    Kaneff, S.

    1984-01-01

    The fourteen dish white cliffs solar power station area is remote and subject to extreme environmental conditions, solution of the associated problems required careful and thoughtful attention and the application of resources. Notwithstanding the wide range and harshness of conditions, the difficulties caused by remoteness and the lack of a technological base and the need for relatively rapid demonstration of success, the project has had a very positive outcome. Qualitative and quantitative information and lessons are now available to enable considerable simplifications to be made for a new system, reducing both hardware and operation and maintenance costs. Experience and lessons are presented, particularly in relation to: system performance in various environmental conditions; design philosophies for collectors, the array, control systems, engine and plant; operation and maintenance strategies and cost reducing possibilities. Experience so far gives encouragement for the future of such paraboloidal dish systems in appropriate areas.

  18. Quantum Gravity Experiments

    Cahill R. T.

    2015-10-01

    Full Text Available A new quantum gravity experiment is reported with the data confirming the generali- sation of the Schrödinger equation to include the interaction of the wave function with dynamical space. Dynamical space turbulence, via this interaction process, raises and lowers the energy of the electron wave function, which is detected by observing conse- quent variations in the electron quantum barrier tunnelling rate in reverse-biased Zener diodes. This process has previously been reported and enabled the measurement of the speed of the dynamical space flow, which is consistent with numerous other detection experiments. The interaction process is dependent on the angle between the dynamical space flow velocity and the direction of the electron flow in the diode, and this depen- dence is experimentally demonstrated. This interaction process explains gravity as an emergent quantum process, so unifying quantum phenomena and gravity. Gravitational waves are easily detected.

    1983-07-01

    A Gross Decontamination Experiment was conducted on various levels and surfaces of the TMI - Unit 2 reactor building in March 1982. The polar crane, D-rings, missile shields, refueling canals, refueling bridges, equipment, and elevations 305' and 347'-6'' were flushed with low pressure water. Additionally, floor surfaces on elevation 305' and floor surfaces and major pieces of equipment on elevation 347'-6'' were sprayed with high pressure water. Selective surfaces were decontaminated with a mechanical scrubber and chemicals. Strippable coating was tested and evaluated on equipment and floor surfaces. The effectiveness, efficiency, and safety of several decontamination techniques were established for the large, complex decontamination effort. Various decontamination equipment was evaluated and its effectiveness was documented. Decontamination training and procedures were documented and evaluated, as were the support system and organization for the experiment.

  20. LASL fast liner experiment

    The LASL Fast Liner Experiment explores a fusion concept in which a prepared plasma is adiabatically compressed to thermonuclear temperatures and densities by a rapidly imploding solid metal liner. A prepared plasma having β > 1 is in contact with the liner and end plugs, and contains an embedded magnetic field to inhibit thermal conduction. Cylindrical liners are magnetically imploded by a large axial current carried in the liner shell. Theoretical estimates indicate an implosion velocity of at least 106 cm/s is necessary for this geometry if the plasma heating rate is to be greater than the cross-field thermal conduction loss rate. Experimental work to develop this concept involves attempts to provide a suitable preplasma for liner implosions as well as studies of magnetically driven liner implosions. In the plasma preparation experiments a coaxial plasma gun was used to inject plasma into a simulated liner geometry

  1. Results of DT experiments

    The results of TFTR DT experiments are reviewed with the author' comments. A maximum fusion power of 10.7MW was produced in TFTR deuterium-tritium (DT) experiments, using nearly equal concentrations of deuterium and tritium. The particle diffusivities of tritium and 4He, and the deuterium thermal diffusivity are of similar magnitudes. Measurements of the loss of alpha particles in DT plasmas show no new loss mechanism. Initial measurements of alpha ash from DT reactions indicate that the transport coefficients of alpha ash are consistent with those for helium introduced to the plasma by gas puffing. DT plasmas with enhanced energy confinement have been obtained in the high poloidal beta. ICRF heating of a DT plasma has demonstrated ion and electron heating. (author)

    2015-01-01

    Data analysis in fundamental sciences nowadays is an essential process that pushes frontiers of our knowledge and leads to new discoveries. At the same time we can see that complexity of those analyses increases fast due to a)~enormous volumes of datasets being analyzed, b)~variety of techniques and algorithms one have to check inside a single analysis, c)~distributed nature of research teams that requires special communication media for knowledge and information exchange between individual researchers. There is a lot of resemblance between techniques and problems arising in the areas of industrial information retrieval and particle physics. To address those problems we propose Reproducible Experiment Platform (REP), a software infrastructure to support collaborative ecosystem for computational science. It is a Python based solution for research teams that allows running computational experiments on shared datasets, obtaining repeatable results, and consistent comparisons of the obtained results. We present s...

  4. Who Needs Business Experience?

    Walter, Achim; Ritter, Thomas; Coviello, Nicole;

    This paper investigates how early internationalization is impacted by certain pre-founding innovation activities of an academic spin-off’s team. Framed in the imprinting, experiential knowledge and network literatures, we combine and assess patent analysis with survey data. Our findings link the...... founding teams’ pre-foundation R&D and customer collaborations to early exports. We also show that pre-foundation involvement in these various forms of collaboration, as well as a diverse stock of prior technical knowledge, can compensate for a lack of business experience in the team. The results also show...... that prior business experience does not predict very early export (within three years). Our results offer fresh insight to the international business and international entrepreneurship literatures, and implications for policy development. In particular, international R&D collaborations at public...

  5. The ATLAS experiment

    Dunford, Monica Lynn

    2014-01-01

    In particle physics experiments, the discovery of increasingly more massive particles has brought deep understanding of the basic constituents of matter and of the fundamental forces among them. In order to explore Nature in its deepest elementary secrets, the Large Hadron Collider (LHC) was built at CERN, Geneva. The LHC provides the highest energy collisions in a laboratory, at very high rates to allow one to study very rare reactions. Two independent sophisticated huge instruments, called ATLAS and CMS detectors, are operated to explore in a most broad way the physics of these collisions. In addition to these two general-purpose detectors, smaller specialized experiments (LHCb, ALICE and some others) are collecting collision data as well.

  6. HTR fuel manufacturing experience

    The development of the HTR line promises the availability of a number of technologies which can be used in many area of energy supply. Special properties of nuclear energy exploitation in high-temperature reactors include economical uranium consumption and lower pollution of the environment. Fuel cycle, design and irradiation performance requirements impose restraints on the fuel elements fabrication processes. Both kernel and coating fabrication processes are flexible enough to adapt to the needs of the various existing and proposed high temperature gas-cooled reactors. Extensive experience has demonstrated that fuel kernels with excellent sphericity and uniformity can be produced by wet chemical processes. Similarly experience has shown that the various multilayer coatings can be produced to fully meet design and specification requirements. In a comprehensive qualification program for fuel elements the low failure fraction of coated fuel particles, optimal matrix behavior and the required fission product retention of integral fuel elements was successfully demonstrated

    2015-06-01

    Full Text Available The study aimed to understand the motherhood experience for prisoners. This is an exploratory-descriptive qualitative study conducted with 17 prisoner women in the Penitentiary System of Paraíba State, during the period of July to December of 2012. A sociodemographic questionnaire and semi-structured interviews were used for data collection. Data were organized and categorized following content analysis, generating three categories: separation suffering; comfort during anguish; family fragmentation. Results pointed out that motherhood experience in the prison is permeated by suffering and limitations. However, the presence of their child creates comfort during anguish and minimize difficulties in prison, although temporarily.  It is necessary to create inter sectoral actions to favor the mother-child relationship in the prison context.

    2011-01-01

    In the wake of present European interest for mapping urban noise, it seems increasingly relevant to investigate the multiple ways in which sound intersects with the everyday experiences of urban citizens. Focusing on the polluting effects of infrastructural noise, the EU-initiated project...... of assessment and management of environmental noise brings forth the disturbing and potentially damaging effect of environmental sound.1 But as maps of coloured streets start to circulate, and real estate prices drop in designated blue and red areas,2 it is worth remembering that sound itself is not a killer....... The challenge for planners, designers, and architects is to deal with the auditory not only as pollution but also as an integrated part of urban experience, promoting fellowship and liveliness as well as distress....

  11. Microwave Tokamak Experiment

    The Microwave Tokamak Experiment, now under construction at the Laboratory, will use microwave heating from a free-electron laser. The intense microwave pulses will be injected into the tokamak to realize several goals, including a demonstration of the effects of localized heat deposition within magnetically confined plasma, a better understanding of energy confinement in tokamaks, and use of the new free-electron laser technology for plasma heating. The experiment, soon to be operational, provides an opportunity to study dense plasmas heated by powers unprecedented in the electron-cyclotron frequency range required by the especially high magnetic fields used with the MTX and needed for reactors. 1 references, 5 figures, 3 tables

  12. The OPERA experiment

    The aim of the OPERA experiment is to provide unambiguous evidence for the νμ ↔ ντ oscillation by looking at the appearance of ντ in a pure νμ beam. This oscillation will be sought in the region of the oscillation parameters indicated by the atmospheric neutrino results. The experiment is part of the CNGS (CERN Neutrino beam to Gran Sasso) project. The νμ beam produced at CERN will be sent towards the Gran Sasso underground laboratory, where the OPERA detector is under construction. The detector, the physics potential, and performance for neutrino oscillation studies including the subleading νμ ↔ νε search are presented

  13. The ECHo experiment

    The determination of the absolute scale of the neutrino masses is one of the most challenging questions in particle physics. Different approaches are followed to achieve a sensitivity on neutrino masses in the sub-eV range. Among them, experiments exploring the beta decay and electron capture processes of suitable nuclides can provide necessary information on the electron neutrino mass value. In this talk we present the Electron Capture 163Ho experiment ECHo, which aims to investigate the electron neutrino mass in the sub-eV range by means of the analysis of the calorimetrically measured energy spectrum following the electron capture process of 163Ho. A high precision and high statistics spectrum is measured by means of low temperature magnetic calorimeter arrays. We present preliminary results obtained with a first prototype of single channel detectors as well as the participating groups and their on-going developments.

    2003-09-01

    Full Text Available The contribution addresses the cross-language experiment. The aimwas to test the possibility of the conversion French phoneme modelsinto Czech ones. This model conversion uses the Hidden Markov Models(HMM classification procedure. The first step consists of theiterative mapping of French models to Czech ones. The mapping is givenby the analysis the confusion matrix. The second step is the Baum-Welchre-estimation resulting in the final models for Czech language. Despiteof the differences between French and Czech languages the finalrecognition score reaches 64% for the phoneme recognition and 74% fordigit recognition. Relatively low recognition accuracy is caused by theinadequate noise model. The experiences gained with the cross-languageexperiment were utilized for the classification of simple human bodymovements. The solution of this problem and results are described inthe second part of this contribution under the title EEG SignalsClassification-Introduction to the Problem.

    In the search for alternatives to reduce the probability of a electric energy shortage, the National Electric Sector decided to apply Real Cost Supply Tariff. The implementation of this tariff method to consumers supplied on low tension, Group B (lower than 2300 Volts), demands a better knowledge of measurement equipment, tariff values and consumers receptivity for energy modulation and/or conservation, all objects of this Yellow Tariff Experience.

    The CONNIE experiment uses fully depleted, high resistivity CCDs as particle detectors in an attempt to measure for the first time the Coherent Neutrino-Nucleus Elastic Scattering of antineutrinos from a nuclear reactor with silicon nuclei.This talk, given at the XV Mexican Workshop on Particles and Fields (MWPF), discussed the potential of CONNIE to perform this measurement, the installation progress at the Angra dos Reis nuclear power plant, as well as the plans for future upgrades.

  19. Phenix - The experience feedback

    The Phenix reactor holds a special place among French nuclear power plants. As a sodium-cooled fast neutron reactor it was quite unique. Built in 1968, by an integrated CEA/EDF/GAAA team, it would go critical in 1973 and be co-operated with EDF (80% CEA-20% EDF) from 1974 to 2009. During the thirty-five year life span, it would play its dual role as electricity generator (250 MWe) and experimental research reactor. Thus, it gathered considerable experience for fast breeder reactor systems: demonstration of design and operation, breeder potential, transmutation possibilities, development of all technical fields involved and validation of the technology used. This book attempts to summarise the wealth of scientifically exciting experience feedback, from these thirty-five years, for future fourth-generation reactors. Contents: 1 - General presentation of the reactor; 2 - Objectives; 3 - Operation review; 4 - Safety review; 5 - Removal of residual power; 6 - Core physics; 7 - Fuel element; 8 - Intermediate heat exchangers; 9 - Steam generators; 10 - Sodium pumps; 11 - Control rods; 12 - Experimental irradiation and in-cell examinations; 13 - Demonstration of transmutation Possibilities; 14 - Results of tests on the reactor; 15 - Final tests; 16 - Materials; 17 - In-service inspection; 18 - Washing, decontamination and repair; 19 - Handling; 20 - Sodium leaks; 21 - Sodium chemistry; 22 Sodium technology; 23 - A positive environmental Report; 24 - Negative reactivity trips; 25 - Reprocessing and multi-recycling; 26 - Co-generation experiment at Phenix; 27 - Phenix's contribution to Superphenix; 28 - Conclusion; Appendix: Experience feedback on the operation of fast reactors around the world

  20. The COMPASS experiment

    Artistic view of the 60 m long Common Muon and Proton Apparatus for Structure and Spectroscopy (COMPASS) experiment. COMPASS takes beams from the SPS accelerator at CERN. This beam enters from the lower left and passes through the cylindrical target solenoid. COMPASS is used to study the internal structure of hadrons (composite particles interacting via the strong force) by looking at a property called spin and a phenomenon known as glueballs.

  1. The ACE experiment

    Maximilien Brice

    2006-01-01

    The Antiproton Cell Experiment (ACE) as shown by Michael Holzscheiter (spokesperson), Niels Bassler (co-spokesperson) and Helge Knudsen. ACE is located on the Antiproton Decelerator (AD) at CERN. An antiproton annihilates a proton in the nucleus of a cancer cell, producing a pair of gamma rays, destroying the entire cell and some surrounding cells. Many fewer antiprotons are required in this treatment than in the equivalent proton hadron therapy, so there is less risk of healthy tissue damage.

  2. CANDU operating experience

    The CANDU (CANada Deuterium Uranium) Pressurized Heavy Water (PHW) type of nuclear-electric generating station was developed jointly by Atomic Energy of Canada Limited and Ontario Hydro. This paper summarizes Ontario Hydro's operating experience using the CANDU-PHW system, with a focus on the operating performance and costs, reliability of system components, and nuclear safety considerations to both the workers and the public

    1973-01-01

    The scientific objectives of the Apollo lunar sounder experiment (ALSE) are (1) mapping of subsurface electrical conductivity structure to infer geological structure, (2) surface profiling to determine lunar topographic variations, (3) surface imaging, and (4) measuring galactic electromagnetic radiation in the lunar environment. The ALSE was a three-frequency, wide-band, coherent radar system operated from lunar orbit during the Apollo 17 mission.

  4. The Vinca dosimetry experiment

    On 15 October 1958 there occurred a very brief uncontrolled run of the zero-power reactor at the Boris Kidric Institute of Nuclear Science, Vinca, near Belgrade, Yugoslavia. During this run six persons received various doses of radiation. They were subsequently given medical treatment of a novel kind at the Curie Hospital, Paris. In atomic energy operations to date, very few accidents involving excessive radiation exposure to human beings have occurred. In fact, the cases of acute radiation injury are limited to about 30 known high exposures, few of which were in the lethal or near-lethal range. Since direct experiment to determine the effects of ionizing radiation on man is unacceptable, information on these effects has to be based on a consideration of data relating to accidental exposures, viewed in the light of the much more extensive data obtained from experiments on animals. Therefore, any direct information on the effects of radiation on humans is very valuable. The international dosimetry project described in this report was carried out at Vinca, Yugoslavia, under the auspices of the International Atomic Energy Agency to determine the precise amount of radiation to which the persons had been exposed during the accident. These dosimetry data, together with the record of the carefully observed clinical effects, are of importance both for the scientific study of radiation effects on man and for the development of methods of therapy. The experiment and measurements were carried out at the end of April 1960. The project formed part of the Agency's research programme in the field of health and safety. The results of the experiment are made available through this report to all Member States

  5. Kernelized design of experiments

    Rüping, Stefan; Weihs, Claus

    2009-01-01

    This paper describes an approach for selecting instances in regression problems in the cases where observations x are readily available, but obtaining labels y is hard. Given a database of observations, an algorithm inspired by statistical design of experiments and kernel methods is presented that selects a set of k instances to be chosen in order to maximize the prediction performance of a support vector machine. It is shown that the algorithm significantly outperforms related approaches on ...

  9. Review of EDM experiments

    The current limits on physics beyond the SM come in large part from the non-observation of EDMs in the sensitive electric dipole moment experiments, like the neutron, 199Hg, and 205Tl. New systems with enhanced EDM sensitivity are coming online and promise a resolution of the baryon asymmetry of our universe (if an EDM is observed) or a severe constraint on physics beyond the SM by the end of the current decade.

  10. The OPERA experiment

    The aim of the OPERA experiment is to provide an unambiguous evidence for the νμ ↔ ντ oscillation by looking at the appearance of ντ in a pure νμ. The νμ beam produced at CERN will be sent towards the Gran Sasso underground laboratory, where OPERA detector is under construction. The detector, the physics potential and performances for neutrino oscillation studies are presented

  11. The MUSE experiment

    Downie E. J.

    2014-01-01

    The proton radius puzzle is the difference between the proton radius as measured with electron scattering and in the excitation spectrum of atomic hydrogen, and that measured with muonic hydrogen spectroscopy. The MUSE experiment seeks to resolve this puzzle by simultaneously measuring elastic electron and muon scattering on the proton, in both charge states, thereby providing new information to the puzzle. MUSE addresses issues of two-photon effects, lepton universality and, possibly, new ph...

    Full Text Available Is the social media hype about being cool or about making money? For Adam Froman, the answer is easy: Marketers need to be very clear about how social media activity supports overall business strategy. Only if the digital experience fi ts into the whole customer journey will consumers become engaged and add value to the company … and only then will the social brand become cool.

  15. Experience and Sociology

    Motamedi-Fraser, Mariam

    2007-01-01

    In preparation for this conference I thought I'd read again C Wright Mills' The Sociological Imagination. Clearly there's a lot in that book about the pitfalls that sociologists face as they bounce about between the fetishisation of the concept on the one hand, and methodological inhibition and pretension on the other. There's much discussion, for example, of the 'unreality' of 'grand theory' which 'neither enlarge[s] our understanding nor make[s] our experience more sensible'; and of the ina...

    Jeschki, Wolfgang

    Numerous articles have been published about the events which occurred at Chernobyl and the radiological impact on the environment and the public. This article tries to find out which experience can be, should be or has already been gained from that accident. The fields which have been studied are: nuclear safety; radiation protection of rescue workers; medical treatment of overexposed persons; decontamination of agricultural land, buildings and cities; behaviour of radionuclides in ecosystems; effects of low doses on human beings.

  17. Reproducible Experiment Platform

    Likhomanenko, Tatiana; Rogozhnikov, Alex; Baranov, Alexander; Khairullin, Egor; Ustyuzhanin, Andrey

    2015-12-01

    Data analysis in fundamental sciences nowadays is an essential process that pushes frontiers of our knowledge and leads to new discoveries. At the same time we can see that complexity of those analyses increases fast due to a) enormous volumes of datasets being analyzed, b) variety of techniques and algorithms one have to check inside a single analysis, c) distributed nature of research teams that requires special communication media for knowledge and information exchange between individual researchers. There is a lot of resemblance between techniques and problems arising in the areas of industrial information retrieval and particle physics. To address those problems we propose Reproducible Experiment Platform (REP), a software infrastructure to support collaborative ecosystem for computational science. It is a Python based solution for research teams that allows running computational experiments on shared datasets, obtaining repeatable results, and consistent comparisons of the obtained results. We present some key features of REP based on case studies which include trigger optimization and physics analysis studies at the LHCb experiment.

  18. Mars brine formation experiment

    Moore, Jeffrey M.; Bullock, Mark A.; Stoker, Carol R.

    1992-01-01

    Evaporites, particularly carbonates, nitrates, and sulfates, may be major sinks of volatiles scavenged from the martian atmosphere. Mars is thought to have once had a denser, warmer atmosphere that permitted the presence of liquid surface water. The conversion of atmospheric CO2 into carbonate is hypothesized to have degraded the martian climate to its present state of a generally subfreezing, desiccated desert. The rate for such a conversion under martian conditions is poorly known, so the time scale of climate degradation by this process cannot be easily evaluated. If some models are correct, carbonate formation may have been fast at geological time scales. The experiments of Booth and Kieffer also imply fast (10(exp 6) - 10(exp 7) yr) removal of the missing CO2 inventory, estimated to be 1 - 5 bar, by means of carbonate formation. The timing of formation of many of the fluvial features observed on Mars is, in large part, dependent on when and how fast the atmosphere changed. A knowledge of the rate at which carbonates and nitrates formed is also essential for assessing the probability that life, or its chemical precursors, could have developed on Mars. No previous experiments have quantitatively evaluated the rate of solution for a suite of mobile anions and cations from unaltered minerals and atmospheric gases into liquid water under Mars-like conditions. Such experiments are the focus of this task.

    2014-01-01

    The OLYMPUS experiment was designed to measure the ratio between the positron-proton and electron-proton elastic scattering cross sections, with the goal of determining the contribution of two-photon exchange to the elastic cross section. Two-photon exchange might resolve the discrepancy between measurements of the proton form factor ratio, $\\mu_p G^p_E/G^p_M$, made using polarization techniques and those made in unpolarized experiments. OLYMPUS operated on the DORIS storage ring at DESY, alternating between 2.01~GeV electron and positron beams incident on an internal hydrogen gas target. The experiment used a toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight detectors to measure rates for elastic scattering over the polar angular range of approximately $25^\\circ$--$75^\\circ$. Symmetric M{\\o}ller/Bhabha calorimeters at $1.29^\\circ$ and telescopes of GEM and MWPC detectors at $12^\\circ$ served as luminosity monitors. A total luminosity of approximately 4.5~fb$^{-1}$ was collect...

  20. Experiments with Electrodynamic Wheels

    Gaul, Nathan; Corey, Daniel; Cordrey, Vincent; Majewski, Walerian

    2015-04-01

    Our experiments were involving inductive magnetic levitation. A Halbach array is a system in which a series of magnets is arranged in a manner such that the magnetic field is cancelled on one side of the array while strengthening the field on the other. We constructed two circular Halbach wheels, making the strong magnetic field on the outer rim of the ring. Such system is usually dubbed as an Electrodynamic Wheel (EDW). Rotating this wheel around a horizontal axis above a flat conducting surface should induce eddy currents in said surface through the variable magnetic flux. The eddy currents produce, in turn, their own magnetic fields which interact with the magnets of the EDW. We demonstrated that these interactions produce both drag and lift forces on the EDW which can theoretically be used for lift and propulsion of the EDW. The focus of our experiments is determining how to maximize the lift-to-drag ratio by the proper choice of the induction element. We will also describe our experiments with a rotating circular Halbach array having the strong magnetic field of about 1 T on the flat side of the ring, and acting as a hovercraft.

  1. Critical experiment data archiving

    Critical experiment facilities produced a large number of important data during the past 45 years; however, many useful data remain unpublished. The unpublished material exists in the form of experimenters' logbooks, notes, photographs, material descriptions, etc., This data could be important for computer code validation, understanding the physics of criticality, facility design, or for setting process limits. In the past, criticality specialists have been able to obtain unpublished details by direct contact with the experimenters. Obviously, this will not be possible indefinitely. Most of the US critical experiment facilities are now closed, and the experimenters are moving to other jobs, retiring, or otherwise becoming unavailable for this informal assistance. Also, the records are in danger of being discarded or lost during facility closures, cleanup activities, or in storage. A project was begun in 1989 to ensure that important unpublished data from critical experiment facilities in the United States are archived and made available as a resource of the US Department of Energy's (DOE's) Nuclear Criticality Information System (NCIS). The objective of this paper is to summarize the project accomplishments to date and bring these activities to the attention of those who might be aware of the location of source information needed for archiving and could assist in getting the materials included in the archive

  4. Fiber Attachment Module Experiment

    Agostini, Reinaldo J.

    2014-01-01

    Hollow Fiber Membrane Bioreactors (HFMB) are ideal systems for biological pretreatment of wastewater, however, optimization is still underway. The Fiber Attachment Module Experiment (FAME) allows the simultaneous testing of potential materials, treatments on these and varying inoculums. Polydimethylsiloxane (PDMS), the material chosen for its ideal oxygen permeation properties, was treated with 1 sodium hydroxide 0.1 M ether for 18 seconds and ultraviolet (UV) irradiation oxygen plasma (OP) exposure for 1 hour. Preliminary chemistry and visual data indicate promising treatments when using OP and sodium hydroxide as treatments for PDMS fibers; however, due to the biological nature of the experiment, time is a constraint. Sodium hydroxide treatment chemistry data shows nitrification is occurring as urea and ammonia are decreasing and nitrite is increasing. A higher amount of biofilm can also be observed for this particular case. During the final two weeks of the internship x-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) and acridine orange (AO) cell counts will be employed for treatment effectiveness on the first batch of treatments (ether and sodium hydroxide). These same strategies will be used for the second batch of experiments due in four weeks (2nd week of August).

  12. Situating emotional experience.

    Wilson-Mendenhall, Christine D; Barrett, Lisa Feldman; Barsalou, Lawrence W

    2013-01-01

    Psychological construction approaches to emotion suggest that emotional experience is situated and dynamic. Fear, for example, is typically studied in a physical danger context (e.g., threatening snake), but in the real world, it often occurs in social contexts, especially those involving social evaluation (e.g., public speaking). Understanding situated emotional experience is critical because adaptive responding is guided by situational context (e.g., inferring the intention of another in a social evaluation situation vs. monitoring the environment in a physical danger situation). In an fMRI study, we assessed situated emotional experience using a newly developed paradigm in which participants vividly imagine different scenarios from a first-person perspective, in this case scenarios involving either social evaluation or physical danger. We hypothesized that distributed neural patterns would underlie immersion in social evaluation and physical danger situations, with shared activity patterns across both situations in multiple sensory modalities and in circuitry involved in integrating salient sensory information, and with unique activity patterns for each situation type in coordinated large-scale networks that reflect situated responding. More specifically, we predicted that networks underlying the social inference and mentalizing involved in responding to a social threat (in regions that make up the "default mode" network) would be reliably more active during social evaluation situations. In contrast, networks underlying the visuospatial attention and action planning involved in responding to a physical threat would be reliably more active during physical danger situations. The results supported these hypotheses. In line with emerging psychological construction approaches, the findings suggest that coordinated brain networks offer a systematic way to interpret the distributed patterns that underlie the diverse situational contexts characterizing emotional life

    Unmanned ground and air systems operating in collaboration have the potential to provide future Joint Forces a significant capability for operations in complex terrain. Ground and air collaborative engagements potentially offer force conservation, perform timely acquisition and dissemination of essential combat information, and can eliminate high value and time critical targets. These engagements can also add considerably to force survivability by reducing soldier and equipment exposure during critical operations. The Office of the Secretary of Defense, Joint Robotics Program (JRP) sponsored Collaborative Engagement Experiment (CEE) is a consolidation of separate Air Force, Army and Navy collaborative efforts to provide a Joint capability. The Air Force Research Laboratory (AFRL), Material and Manufacturing Directorate, Aerospace Expeditionary Force Division, Force Protection Branch (AFRLMLQF), The Army Aviation and Missile Research, Development and Engineering Center (AMRDEC) Joint Technology Center (JTC)/Systems Integration Laboratory (SIL), and the Space and Naval Warfare Systems Center-San Diego (SSC San Diego) are conducting technical research and proof of principle for an envisioned operational concept for extended range, three dimensional, collaborative operations between unmanned systems, with enhanced situational awareness for lethal operations in complex terrain. This program will assess information requirements and conduct experiments to identify and resolve technical risks for collaborative engagements using Unmanned Ground Vehicles (UGVs) and Unmanned Aerial Vehicles (UAVs). It will research, develop and physically integrate multiple unmanned systems and conduct live collaborative experiments. Modeling and Simulation systems will be upgraded to reflect engineering fidelity levels to greater understand technical challenges to operate as a team. This paper will provide an update of a multi-year program and will concentrate primarily on the JTC

  15. 2169 steel waveform experiments.

    2012-11-01

    In support of LLNL efforts to develop multiscale models of a variety of materials, we have performed a set of eight gas gun impact experiments on 2169 steel (21% Cr, 6% Ni, 9% Mn, balance predominantly Fe). These experiments provided carefully controlled shock, reshock and release velocimetry data, with initial shock stresses ranging from 10 to 50 GPa (particle velocities from 0.25 to 1.05 km/s). Both windowed and free-surface measurements were included in this experiment set to increase the utility of the data set, as were samples ranging in thickness from 1 to 5 mm. Target physical phenomena included the elastic/plastic transition (Hugoniot elastic limit), the Hugoniot, any phase transition phenomena, and the release path (windowed and free-surface). The Hugoniot was found to be nearly linear, with no indications of the Fe - phase transition. Releases were non-hysteretic, and relatively consistent between 3- and 5-mm-thick samples (the 3 mm samples giving slightly lower wavespeeds on release). Reshock tests with explosively welded impactors produced clean results; those with glue bonds showed transient releases prior to the arrival of the reshock, reducing their usefulness for deriving strength information. The free-surface samples, which were steps on a single piece of steel, showed lower wavespeeds for thin (1 mm) samples than for thicker (2 or 4 mm) samples. A configuration used for the last three shots allows release information to be determined from these free surface samples. The sample strength appears to increase with stress from ~1 GPa to ~ 3 GPa over this range, consistent with other recent work but about 40% above the Steinberg model.

  16. Magnetohydrodynamic Augmented Propulsion Experiment

    Litchford, Ron J.; Cole, John; Lineberry, John; Chapman, Jim; Schmidt, Harold; Cook, Stephen (Technical Monitor)

    2002-01-01

    A fundamental obstacle to routine space access is the specific energy limitations associated with chemical fuels. In the case of vertical take-off, the high thrust needed for vertical liftoff and acceleration to orbit translates into power levels in the 10 GW range. Furthermore, useful payload mass fractions are possible only if the exhaust particle energy (i.e., exhaust velocity) is much greater than that available with traditional chemical propulsion. The electronic binding energy released by the best chemical reactions (e.g., LOX/LH2 for example, is less than 2 eV per product molecule (approx. 1.8 eV per H2O molecule), which translates into particle velocities less than 5 km/s. Useful payload fractions, however, will require exhaust velocities exceeding 15 km/s (i.e., particle energies greater than 20 eV). As an added challenge, the envisioned hypothetical RLV (reusable launch vehicle) should accomplish these amazing performance feats while providing relatively low acceleration levels to orbit (2-3g maximum). From such fundamental considerations, it is painfully obvious that planned and current RLV solutions based on chemical fuels alone represent only a temporary solution and can only result in minor gains, at best. What is truly needed is a revolutionary approach that will dramatically reduce the amount of fuel and size of the launch vehicle. This implies the need for new compact high-power energy sources as well as advanced accelerator technologies for increasing engine exhaust velocity. Electromagnetic acceleration techniques are of immense interest since they can be used to circumvent the thermal limits associated with conventional propulsion systems. This paper describes the Magnetohydrodynamic Augmented Propulsion Experiment (MAPX) being undertaken at NASA Marshall Space Flight Center (MSFC). In this experiment, a 1-MW arc heater is being used as a feeder for a 1-MW magnetohydrodynamic (MHD) accelerator. The purpose of the experiment is to demonstrate

  17. French experience with electropolishing

    Following the results obtained in CHINON B1 comparing deposited activity observed on different surface finishes EDF decided to electropolish steam generator channel heads (S.G.C.H.) in order to reduce operator dose during plant maintenance. The qualification tests were performed on steam generator materials (Inconel 600 and S.S. 308 L) with the full on site operational equipment (i.e. a sealed sucker). In 1988 the 4 SGCH of NOGENT 2 were electropolished. In 1990 we observed a dose rate reduction of 45% at NOGENT 2 compared to NOGENT 1. Other French experience is electropolishing of 27 S.G.C.H., since 1988. (author)

  18. Ontario Hydro decontamination experience

    Ontario Hydro currently operates 18 nuclear electric generating units of the CANDU design with a net capacity of 12,402 MW(e). An additional 1,762 MW(e) is under construction. The operation of these facilities has underlined the need to have decontamination capability both to reduce radiation fields, as well as to control and reduce contamination during component maintenance. This paper presents Ontario Hydro decontamination experience in two key areas - full heat transport decontamination to reduce system radiation fields, and component decontamination to reduce loose contamination particularly as practised in maintenance and decontamination centres.

    The Apollo 15 soil-mechanics experiment has offered greater opportunity for study of the mechanical properties of the lunar soil than previous missions, not only because of the extended lunar-surface stay time and enhanced mobility provided by the lunar roving vehicle (rover), but also because four new data sources were available for the first time. These sources were: (1) the self-recording penetrometer (SRP), (2) new, larger diameter, thin-walled core tubes, (3) the rover, and (4) the Apollo lunar-surface drill (ALSD). These data sources have provided the best bases for quantitative analyses thus far available in the Apollo Program.

    The present status of experimental solar neutrino research is reviewed. Updated results from the Homestake, Kamiokande, GALLEX and SAGE detectors all show a deficit when compared to recent standard solar model calculations. Two of these detectors, GALLEX and SAGE, have recently been checked with artificial {sup 51}Cr neutrino sources. It is shown that astrophysical scenarios to solve the solar neutrino problems are not favoured by the data. There is hope that the results of forthcoming solar neutrino experiments can provide the answers to the open questions. (author) 6 figs., 3 tabs., 36 refs.

  14. Experience in open markets

    The topic of discussion in this session was experience in open markets. The session was led by Guido Bachman, President of the Independent Power Producers' Society of Alberta (IPPSA), assisted by panel members Richard Way, Director of Energy Risk Management at TransAlta, John O'Donnell, Professor of Finance at Michigan State University, and Kelly Lail, Manager of Power Acquisition at B.C. Hydro. Way spoke of the experiences with market restructuring in Alberta, describing the consultative and legislative process which determined the structure of the Alberta Power Pool (APP). The Pool began operations in January 1996. Currently there are 33 participants from generators, to distributors and marketers. Supply and demand are managed by APP by setting an hourly price based on offers and bids. Both generators and distributors get the hourly pool price, so the input price and export price of the pool are the same, however, generators and distributors are free to enter into 'contract for difference' agreements. O'Donnell discussed the status of competition in Michigan. He stressed the importance of Ontario to the Michigan market, echoing the conviction of U.S. regulators that a freer economy works better. Kelly Lail spoke of the unbundling of B.C. Hydro into several generating, transmission and distribution companies in preparation for moving from exclusive service to exclusive wholesale competition. He predicted that the fierce competition will lead to a an industry shakeout, leaving only one big (B.C. Hydro) and a few niche players

  15. The EBEX Experiment

    EBEX is a balloon-borne polarimeter designed to measure the intensity and polarization of the cosmic microwave background radiation. The measurements would probe the inflationary epoch that took place shortly after the big bang and would significantly improve constraints on the values of several cosmological parameters. EBEX is unique in its broad frequency coverage and in its ability to provide critical information about the level of polarized Galactic foregrounds which will be necessary for all future CMB polarization experiments. EBEX consists of a 1.5 m Dragone-type telescope that provides a resolution of less than 8 arcminutes over four focal planes each of 4. diffraction limited field of view at frequencies up to 450 GHz. The experiment is designed to accommodate 330 transition edge bolometric detectors per focal plane, for a total of up to 1320 detectors. EBEX will operate with frequency bands centered at 150, 250, 350, and 450 GHz. Polarimetry is achieved with a rotating achromatic half-wave plate. EBEX is currently in the design and construction phase, and first light is scheduled for 2008

  16. The NEXT experiment

    Gomez-Cadenas, Juan Jose

    2014-01-01

    NEXT (Neutrino Experiment with a Xenon TPC) is an experiment to search neutrinoless double beta decay processes (bb0nu) in Xe136. The NEXT technology is based in the use of time projection chambers operating at a typical pressure of 15 bar and using electroluminescence to amplify the signal (HPXE). The main advantages of the experimental technique are: a) excellent energy resolution; b) the ability to reconstruct the trajectory of the two electrons emitted in the decays, which further contributes to the suppression of backgrounds; c) scalability to large masses; and d) the possibility to reduce the background to negligible levels thanks to the barium tagging technology (BATA). The NEXT roadmap was designed in four stages: i) Demonstration of the HPXE technology with prototypes deploying a mass of natural xenon in the range of 1 kg, using the NEXT-DEMO (IFIC) and NEXT-DBDM (Berkeley) prototypes; ii) Characterisation of the backgrounds to the bb0nu signal and measurement of the bb2nu signal with the NEW detecto...

  17. Initiation Train Experiments

    2015-06-01

    In an effort to evaluate and qualify a new detonator diagnostic, booster selection and main charge configuration, a variety of small-scale tests have been conducted. This paper will describe the needs, testing approach and model validation. Because of the limited size available some novel approaches were made to understand the observed phenomenon. Function time and time of arrival at various locations in the initiation train are desirable data points. Knowing when each segment initiates the next segment and the time to run up to detonation is critical. Results of our experiments were modeled for timing accuracy, wave shape and pressure. Agreement between the experiments and models will be discussed. The testing that will be discussed is time of arrival wires, PDV, and fiber optic arrays. The time of arrival wire measures the detonator cup breakout time. When correlated to bridge burst, an absolute time is collected. This data point also gives time zero for the booster initiation. Many models actually start at the booster, rather than the detonator, so the inclusion of this data point will improve modeling efforts.

  18. The STARTRACK experiment.

    Denardo, L; Conte, V; Poggi, M; Canella, S; Colautti, P; Moro, D; Tornielli, G

    2007-01-01

    STARTRACK is the acronym of an experiment that aims to measure ionisation cluster distributions in nanometric sites placed at different distances from an accelerated charged particle track. STARTRACK will first use the 20 nm wall-less detector, already used for studying the nanometric track structure of an alpha particle, and then a new detector designed for measuring ionisation clusters in 10 nm sites. The experiment is mounted on the beam line of the Tandem-Alpi accelerator facility of the Legnaro Laboratories, which supplies ion beams from hydrogen to gold up to energy ranging from 7 to 28 MeV/amu. Track nanodosimetry aims to measure ionisation clusters along and aside the ion track down to occurrence probability of 10(-5). To reach such a goal at least 10(6) events have to be collected and the cluster pile-up probability has to be reduced to less than 10(-6). By using a beam profile detector, which is sensitive to very weak currents, and an event rejector counter, such an aim is feasible. PMID:17562652

  19. Female physicist doctoral experiences

    Dabney, Katherine P.; Tai, Robert H.

    2013-06-01

    The underrepresentation of women in physics doctorate programs and in tenured academic positions indicates a need to evaluate what may influence their career choice and persistence. This qualitative paper examines eleven females in physics doctoral programs and professional science positions in order to provide a more thorough understanding of why and how women make career choices based on aspects both inside and outside of school and their subsequent interaction. Results indicate that female physicists experience conflict in achieving balance within their graduate school experiences and personal lives and that this then influences their view of their future careers and possible career choices. Female physicists report both early and long-term support outside of school by family, and later departmental support, as being essential to their persistence within the field. A greater focus on informal and out-of-school science activities for females, especially those that involve family members, early in life may help influence their entrance into a physics career later in life. Departmental support, through advisers, mentors, peers, and women’s support groups, with a focus on work-life balance can help females to complete graduate school and persist into an academic career.

These experiments provided shock, reshock and release velocimetry data, with initial shock stresses ranging from 10 to 50 GPa (particle velocities from 0.25 to 1.05 km/s). Both windowed and free-surface measurements were used, with samples 1 to 5 mm thick. The study focused on dynamic strength determination via the release/reshock paths. Reshock tests with explosively welded impactors produced clean results. The free-surface samples, which were steps on a single piece of steel, showed lower wavespeeds for thin (1 mm) samples than for thicker (2 or 4 mm) samples. A configuration used for the last three shots allowed release information to be determined from these free surface samples as well. The sample strength appears to increase with stress from ~1 GPa to ~3 GPa over this range, consistent with other recent work but about 40% above the Steinberg model.

    Planning has started towards designing a new field campaign aimed at studying the behaviour of the boundary layer over complex terrain. Of specific interest is the formation of cold-pools in valleys during stable night-time conditions. The field campaign will run continuously until the end of the winter in 2009/10. The experiment will make use of a wide variety of ground-based sensors including turbulence towers, automatic weather stations, Doppler lidar, radiation sensors and soil temperature probes. We also hope to deploy an instrumented car and a tethered balloon facility for limited periods. Data from the field campaign will be used for a number of purposes. Firstly, to increase our understanding of how the valley cold pools form and why, for instance, some valleys offer a more favourable environment for their formation than others. Secondly, to investigate the formation and dissipation of fog in complex terrain. Thirdly, the data set will also be used to help validate and develop the Met Office Unified Model at high resolution. An area for the experiment has been identified in the Shropshire/Powis area of the UK where a network of valleys and low hills exist with a typical valley width of ~1.5km and hill top to valley floor heights of 75-200m. 0m.

  2. PAC Experiments at ISOLDE

    2002-01-01

    The study of hyperfine interactions offers the possibility to use radioactive nuclei as probes in matter. The @g-@g perturbated angular correlation (PAC) technique following implantation has found widespread application in this field. At ISOLDE we have been investigating electric field gradients at impurities in non-cubic metals in an ongoing series of experiments. \\\\ \\\\ The small number of probe atoms necessary for these measurements make them also ideally suited for studies of surface problems like diffusion, structure and dynamics. Cd on a molybdenum O110? surface will be studied as first system. For this purpose 10|1|0~atoms of |1|1|1|mCd will be evaporated onto the clean surface and the electric field gradient for isolated adatoms on terrace sites will be determined by PAC. The UHV system constructed for such experiments at ISOLDE is shown in the schematic drawing. It is coupled to the beam line through differential pumping stations and contains standard surface treatment and analysis equipment.

  3. Advanced Liquid Feed Experiment

    1993-06-01

    The Advanced Liquid Feed Experiment (ALFE) is a Hitchhiker experiment flown on board the Shuttle of STS-39 as part of the Space Test Payload-1 (STP-1). The purpose of ALFE is to evaluate new propellant management components and operations under the low gravity flight environment of the Space Shuttle for eventual use in an advanced spacecraft feed system. These components and operations include an electronic pressure regulator, an ultrasonic flowmeter, an ultrasonic point sensor gage, and on-orbit refill of an auxiliary propellant tank. The tests are performed with two transparent tanks with dyed Freon 113, observed by a camera and controlled by ground commands and an on-board computer. Results show that the electronic pressure regulator provides smooth pressure ramp-up, sustained pressure control, and the flexibility to change pressure settings in flight. The ultrasonic flowmeter accurately measures flow and detects gas ingestion. The ultrasonic point sensors function well in space, but not as a gage during sustained low-gravity conditions, as they, like other point gages, are subject to the uncertainties of propellant geometry in a given tank. Propellant transfer operations can be performed with liquid-free ullage equalization at a 20 percent fill level, gas-free liquid transfer from 20-65 percent fill level, minimal slosh, and can be automated.

  5. The CAST experiment

    CAST (CERN Axion Solar Telescope) is a helioscope looking for axions coming from the solar core to the Earth. The experiment, located at CERN, is based on the Primakoff effect and uses a magnetic field of 9 Tesla provided by a decommissioned LHC magnet. CAST is able to follow the Sun during sunrise and sunset and therefore three X-ray detectors are mounted on both ends of the magnet waiting for a photon from axion-to-photon conversion due to the Primakoff effect. During its first phase, which concluded in 2004, CAST has been looking for axions with masses up to 0.02 eV. CAST's second phase manages to re-establish the coherence needed to scan for axions with masses up to 1.16 eV by using a buffer gas. This technique enables the experiment to look into the theoretical regions for axions. During the years 2005 and 2006, the use of 4He in CAST has already provided coherence in order to look for axions with masses up to 0.4 eV

The experiment is designed to accommodate 330 transition edge bolometric detectors per focal plane, for a total of up to 1320 detectors. EBEX will operate with frequency bands centered at 150, 250, 350, and 450 GHz. Polarimetry is achieved with a rotating achromatic half-wave pla...

  7. Cusp Injection Experiment

    A brief survey is given of the characteristics of the β = 1 cusped configuration and the experimental techniques for establishing hot field-free cusped plasmas. Results from the cusp compression experiments at the Culham Laboratory are summarised and it is concluded that wall and external plasma effects make it extremely difficult to obtain a cusp hole of size less than an ion gyro-diameter by the compression method. An injection technique is described in which hot field-free plasma is transferred from a conical theta-pinch gun through a uniform magnetic guide field into a cusped field region where directed energy is randomised by collision with counter-streaming plasma. Experimental results are presented on gun development, on the injection of plasma into guide fields and on the stability of flow of plasma ''spears'' along guide fields. Preliminary measurements on plasma trapping in a cusped region are reported. Experiments on the collision of plasmas in guide field and zero field show the importance of very low magnitude trapped magnetic fields in causing strong interaction and randomisation of directed energy. The study of a magnetic mirror plasma formed by colliding plasma spears indicates that thermal conductivity may be the major energy loss process. (author)

  8. The Halogen Occultation Experiment

    Russell, James M., III; Gordley, Larry L.; Park, Jae H.; Drayson, S. R.; Hesketh, W. D.; Cicerone, Ralph J.; Tuck, Adrian F.; Frederick, John E.; Harries, John E.; Crutzen, Paul J.

    1993-01-01

    The Halogen Occultation Experiment (HALOE) uses solar occultation to measure vertical profiles of O3, HCl, HF, CH4, H2O, NO, NO2, aerosol extinction, and temperature versus pressure with an instantaneous vertical field of view of 1.6 km at the earth limb. Latitudinal coverage is from 80 deg S to 80 deg N over the course of 1 year and includes extensive observations of the Antarctic region during spring. The altitude range of the measurements extends from about 15 km to about 60-130 km, depending on channel. Experiment operations have been essentially flawless, and all performance criteria either meet or exceed specifications. Internal data consistency checks, comparisons with correlative measurements, and qualitative comparisons with 1985 atmospheric trace molecule spectroscopy (ATMOS) results are in good agreement. Examples of pressure versus latitude cross sections and a global orthographic projection for the September 21 to October 15, 1992, period show the utility of CH4, HF, and H2O as tracers, the occurrence of dehydration in the Antarctic lower stratosphere, the presence of the water vapor hygropause in the tropics, evidence of Antarctic air in the tropics, the influence of Hadley tropical upwelling, and the first global distribution of HCl, HF, and NO throughout the stratosphere. Nitric oxide measurements extend through the lower thermosphere.

  9. Compact toroid formation experiments

    We present the design and experimental performance of a compact toroid (CT) formation experiment. The device has co-axial electrode diameters of 0.9 m (inner) and 1.25 m (outer), and an electrode length of ∼ 1.2 m, including an expansion/drift section. The CT is formed by a 0.1--0.2 Tesla initial radial magnetic field embedded co-axial puff gas discharge. The gas puff is injected with an array of 60 pulsed solenoid driven fast valves. The formation discharge is driven by a 108 microfarad, 40 to 100 KV, 86 to 540 kilojoule 2 to 5 megamp capacitor discharge with ∼ 20 nanohenry initial total discharge inductance. The hardware includes transmission line connections for a Shiva Star (1300 microfarad, up to 120 KV, 0.4 megajoule) capacitor bank driven acceleration discharge. Experimental measurements include current, voltage; azimuthal, radial and axial magnetic field at numerous location; fast photography, optical spectroscopy; microwave, CO2 laser, and He-Ne laser interferometry. Auxiliary experiments include Penning ionization gauge, pressure probe, and breakdown gas trigger diagnostics of gas injection, and Hall probe measurements of magnetic field injection

  10. The VIP Experiment

    The Pauli Exclusion Principle (PEP) is a basic principle of Quantum Mechanics, and its validity has never been seriously challenged. However, given its importance, it is very important to check it as thoroughly as possible. The recently approved VIP (VIolation of Pep) experiment, represents an improved version of the Ramberg and Snow experiment (Ramberg and Snow, Phys. Lett. B238 (1990) 438). VIP shall be performed at the Gran Sasso underground laboratories, and aims to test the Pauli Exclusion Principle for electrons with unprecedented accuracy. VIP is a Collaboration among four Institutions out of three countries (LNF-INFN, and INFN Trieste Italy; SMI-Vienna, Austria; IFIN-HH, Bucharest, Romania). It uses an apparatus with CCDs (Charge Coupled Device) as detectors of X rays - looking for PEP violating transitions in Copper: transitions from the 2p level to 1s with the 1s already occupied by 2 electrons. The characteristic of such transition is the energy - displaced with respect to the normal 2p → 1s one by about 300 eV. VIP will bring the limit on the probability that PEP is violated by electrons to 10-30, exploring so a region where new theories allow for a possible PEP violation. (authors)

  11. The Virtual Arizona Experience

    Allison, M. L.; Davis, R.; Conway, F. M.; Bellasai, R.

    2012-12-01

    To commemorate the once-in-a-lifetime event of Arizona's hundredth birthday, the Centennial Commission and the Governor of Arizona envisioned a museum and companion website that would capture the state's history, celebrate its people, and embrace its future. Working with world-renowned museum designers, the state began to seek ideas from across Arizona to create plans for a journey of discovery through science and the humanities. The museum would introduce visitors to some of the people who nurtured the state through its early years and others who are innovating its tomorrows. Showcases would include the resources and experiences that shaped the state's history and are transforming its present day, highlighting the ingenuity that tamed the wild frontier and is envisioning Arizona's next frontiers through science and technology. The Arizona Experience (www.arizonaexperience.org) was initially intended to serve as the web presence for the physical museum, but as delays occurred with the physical museum, the site has quickly developed an identify of its own as an interactive, multimedia experience, reaching a wider audience with functions that would be difficult or expensive to produce in a museum. As leaders in scientific and technological innovation in the state, the Arizona Geological Survey was tasked with designing and creating the Arizona Experience site. The general themes remain the same; however, the site has added content and applications that are better suited to the online environment in order to create a rich, dynamic supplement to a physical museum experience. The website offers the features and displays of the future museum with the interactive nature and learning environment of the web. This provides an encyclopedic overview of the State of Arizona by subject matter experts in a manner that is free and open to the public and erases socio-economic, political, and physical boundaries. Over the Centennial Year of 2012 the site will release a new theme and

  12. Aesthetic experience of dance performances

    Vukadinović Maja

    2012-01-01

    Full Text Available In this study the aesthetic experience of dance performances is investigated. The study includes construction of an instrument for measuring the aesthetic experience of dance performances and an investigation of the structure of both dancers’ and spectators’ aesthetic experience. The experiments are carried out during eight different performances of various dance forms, including classical ballet, contemporary dance, flamenco and folklore. Three factors of aesthetic experience of dance performances are identified: Dynamism, Exceptionality and Affective Evaluation. The results show that dancers’ aesthetic experience has a somewhat different factorial structure from that of the spectators’. Unlike spectators’ aesthetic experience, dancers’ aesthetic experience singles out the Excitement factor. The results are discussed within the context of dancers’ proprioception and spectators’ exteroception since these findings confirm the idea of a significant role of proprioception in dancers’ aesthetic experience.

    This experiment observed the evolution of metabolite plumes from a human trapped in a simulation of a collapsed building. Ten participants took it in turns over five days to lie in a simulation of a collapsed building and eight of them completed the 6 h protocol while their breath, sweat and skin metabolites were passed through a simulation of a collapsed glass-clad reinforced-concrete building. Safety, welfare and environmental parameters were monitored continuously, and active adsorbent sampling for thermal desorption GC-MS, on-line and embedded CO, CO(2) and O(2) monitoring, aspirating ion mobility spectrometry with integrated semiconductor gas sensors, direct injection GC-ion mobility spectrometry, active sampling thermal desorption GC-differential mobility spectrometry and a prototype remote early detection system for survivor location were used to monitor the evolution of the metabolite plumes that were generated. Oxygen levels within the void simulator were allowed to fall no lower than 19.1% (v). Concurrent levels of carbon dioxide built up to an average level of 1.6% (v) in the breathing zone of the participants. Temperature, humidity, carbon dioxide levels and the physiological measurements were consistent with a reproducible methodology that enabled the metabolite plumes to be sampled and characterized from the different parts of the experiment. Welfare and safety data were satisfactory with pulse rates, blood pressures and oxygenation, all within levels consistent with healthy adults. Up to 12 in-test welfare assessments per participant and a six-week follow-up Stanford Acute Stress Response Questionnaire indicated that the researchers and participants did not experience any adverse effects from their involvement in the study. Preliminary observations confirmed that CO(2), NH(3) and acetone were effective markers for trapped humans, although interactions with water absorbed in building debris needed further study. An unexpected observation from the NH(3

  14. Experience Report for WOPR

    Pope, G

    2010-04-06

    One of the purposes of the SQA effort at LLNL is to attempt to determine the 'goodness' of the research codes used for various scientific applications. Typically these are two and three dimensional multi-physics simulation and modeling codes. These legacy research codes are used for applciations such as atmospheric dispersion modeling and analysis and prediction of the performance of engineered systems. These codes are continually subjected to automated regression test suites consisting of verified and validated expected results. Code is managed in repositories. Experience level of developers is high in the knowledge domain, platforms, and languages used. Code size of the multi-physics code used in this study was 578,242 lines excluding comment and blank lines or 5538.7 function points. Languages were 70% C++, 20% C, and 10% Fortran. The code has 130 users and a development team of 14 and an embedded SQE. The code has achieved 100% prime feature test coverage, 73.6% functional test coverage, and 71.5% statement test coverage. The average cyclomatic complexity of the code was 6.25. The codes have evolved over 10 years. Research codes are challenging because there is a desire to balance agility with discipline as well as compliance with DOE standards. Agility is important to allow experimentation with new algorithms and addition of the latest physics features. Discipline is important to increase the quality of the codes. Automation of processes and defect prevention/detection are deployed throughout the software development process. Since resarch codes are a small segment of the software industry, not much information exists in terms of reliability studies on these types of codes. This paper describes attempts to determine the goodness of these research codes. Goodness defined as both correctness of the codes and their fault densities. Correctness is determined by user interviews, peer review; feature based automated testing, and coverage measurement. This

  15. Limit experiments of GARCH

    Buchmann, Boris; 10.3150/10-BEJ328

    2012-01-01

    GARCH is one of the most prominent nonlinear time series models, both widely applied and thoroughly studied. Recently, it has been shown that the COGARCH model (which was introduced a few years ago by Kl\\"{u}ppelberg, Lindner and Maller) and Nelson's diffusion limit are the only functional continuous-time limits of GARCH in distribution. In contrast to Nelson's diffusion limit, COGARCH reproduces most of the stylized facts of financial time series. Since it has been proven that Nelson's diffusion is not asymptotically equivalent to GARCH in deficiency, in the present paper, we investigate the relation between GARCH and COGARCH in Le Cam's framework of statistical equivalence. We show that GARCH converges generically to COGARCH, even in deficiency, provided that the volatility processes are observed. Hence, from a theoretical point of view, COGARCH can indeed be considered as a continuous-time equivalent to GARCH. Otherwise, when the observations are incomplete, GARCH still has a limiting experiment, which we ...

  16. Industrial experience with titanium

    Titanium is a reference material for the construction of waste containers in the Canadian Nuclear Fuel Waste Management Program. It has been in industrial service for over 30 a, often in severe corrosion environments, but it is still considered a relatively exotic material with limited operating history. This has arisen because of the aerospace applications of this material and the misconception that the high strength-to-weight ratio dominates the choice of this material. In fact, the advantage of titanium lies in its high reliability and excellent corrosion resistance. It has a proven record in seawater heat exchanger service and a demonstrated excellent reliability even in polluted water. For many reasons it is the technically correct choice of material for marine applications. In this report we review the industrial service history of titanium, particularly in hot saline environments, and demonstrate that it is a viable waste container material, based upon this industrial service history and operating experience.

  17. Customer experiences and expectations

    Customer experiences and expectations from competition and cogeneration in the power industry were reviewed by Charles Morton, Director of Energy at CPC International, by describing Casco's decision to get into cogeneration in the early 1990s in three small corn milling plants in Cardinal, London and Port Colborne, Ontario, mainly as result of the threat of a 40 per cent increase in power prices. He stressed that cost competitiveness of cogeneration is entirely site-specific, but it is generally more attractive in larger facilities that operate 24 hours a day, where grid power is expensive or unreliable. Because it is reliable, cogeneration holds out the prospect of increased production-up time, as well as offering a hedge against higher energy costs, reducing the company's variable costs when incoming revenues fall short of costs, and providing an additional tool in head-to-head competition

  18. Reviewing operational experience feedback

    The purpose of this document is to provide detailed supplementary guidance to OSART experts to aid in the evaluation of operational experience feedback (OEF) programmes at nuclear power plants. The document begins by describing the objectives of an OEF programme. It goes on to indicate preparatory work and investigatory guidance for the expert. Section 5 describes attributes of an excellent OEF programme. Appended to these guidelines are examples of OEF documents from various plants. These are intended to help the expert by demonstrating the actual implementation of OEF in practice. These guidelines are in no way intended to conflict with existing national regulations and rules. A comprehensive OEF programme, as described in Section 2, would be impossible to evaluated in detail in the amount of time typically allocated for assessing OEF in an OSART review. The expert must use his or her time wisely by concentrating on those areas that appear to be the weakest

  19. "Experience and Learning"

    Olesen, Henning Salling

    2007-01-01

    Taking it's point of departure in some critical remarks to some of the most important recent theorizing of learning in the workplace, this chapter presents an alternative framework for theorizing learning as a subjective process in a social and societal context, based in life history research. Key...... concepts derived from European critical theory, subjectivity and experience, are briefly introduced with a view to their intellectual background. The chapter elaborates the implication of these concepts in relation to the understanding of emotional aspects of learning in everyday work life and in relation...... to the understanding of knowledge, based on examples from the author's research into professional learning (general practitioners). The pivotal role of language use and language socialisation is explained in brief, developing a psychodynamic complement to a language game concept of language use....

  20. The Bumpy Torus Experiment

    Cobble, James Allen [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    2016-06-09

    This document summarizes the Bumpy Torus Experiment as a viable fusion reactor concept. Conclusions reached include the following: In 30 years, order-of-magnitude technological advances have occurred in multiple areas of plasma heating and confinement. The ORNL bumpy torus of the 1970s was technology limited. Now that ITER is technology limited, an alternate concept is needed. A device built on such a concept should be current free, CW, modular, have a gentle shutdown, and demonstrable stability. The bumpy torus meets or has the potential to meet all of these criteria. Earlier, stability was not possible due to power limits; it has not been fully tested. It is time to revisit the bumpy-torus concept with a modest new machine.

  1. The KATRIN experiment

    Beck, Marcus; Katrin Collaboration

    2010-01-01

    The KArlsruhe TRitium Neutrino mass experiment, KATRIN, aims to search for the mass of the electron neutrino with a sensitivity of 0.2eV/c2 (90% C.L.) and a detection limit of 0.35 eV/c2 (5σ). Both a positive or a negative result will have far reaching implications for cosmology and the standard model of particle physics and will give new input for astroparticle physics and cosmology. The major components of KATRIN are being set up at the Karlsruhe Institut of Technology in Karlsruhe, Germany, and test measurements of the individual components have started. Data taking with tritium is scheduled to start in 2012.

  2. Reactor operation experience

    Since the TRIGA Users Conference in Helsinki 1970 the TRIGA reactor Vienna was in operation without any larger undesired shutdown. The integrated thermal power production by August 15 1972 accumulated to 110 MWd. The TRIGA reactor is manly used for training of students, for scientific courses and research work. Cooperation with industry increased in the last two years either in form of research or in performing training courses. Close cooperation is also maintained with the IAEA, samples are irradiated and courses on various fields are arranged. Maintenance work was performed on the heat exchanger and to replace the shim rod magnet. With the view on the future power upgrading nine fuel elements type 110 have been ordered recently. Experiments, performed currently on the reactor are presented in details

  3. The PANTHER User Experience

    Coram, Jamie L. [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States); Morrow, James D. [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States); Perkins, David Nikolaus [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)

    2015-09-01

    This document describes the PANTHER R&D Application, a proof-of-concept user interface application developed under the PANTHER Grand Challenge LDRD. The purpose of the application is to explore interaction models for graph analytics, drive algorithmic improvements from an end-user point of view, and support demonstration of PANTHER technologies to potential customers. The R&D Application implements a graph-centric interaction model that exposes analysts to the algorithms contained within the GeoGraphy graph analytics library. Users define geospatial-temporal semantic graph queries by constructing search templates based on nodes, edges, and the constraints among them. Users then analyze the results of the queries using both geo-spatial and temporal visualizations. Development of this application has made user experience an explicit driver for project and algorithmic level decisions that will affect how analysts one day make use of PANTHER technologies.

  4. CAREER GUIDANCE EXPERIENCE ABROAD

    Sergey N. Tolstoguzov

    2015-01-01

    Full Text Available The aim of this paper is to describe the experience of careeroriented activities carried out with students of schools in developed and developing countries. Career Guidance in Russia, despite the vast experience of its implementation, is experiencing serious difficulties. In this regard, it is important to take into account the international experience career-oriented activities, such as in the developed countries of North America and the European Union as well as in several Asian countries with rapidly growing economies and a large demographic potential, taking into account the best variants for the Russian education system. Methods. The experience of career-oriented work undertaken with pupils of the USA, Canada, Israel, France, UK, Germany, Denmark, Sweden, Japan, Singapore, China and India is shown on the basis of the comparative analysis of different publications and information sources. The author has made an attempt to generalize the principles of psycho-pedagogical and administrative assistance in professional self-determination of senior pupils abroad. Scientific novelty. The approaches to career-oriented activities in countries with different levels of economic development are compared for the first time. Some principles are revealed. Firstly, the higher the income level per capita in the country, the greater attention is given to vocational guidance. The politics in the developed countries is based on interests of the individual: children’s acquaintance with the world of professions begins already at younger school and the moment of definitive selfdetermination is postponed till the end of their senior stage of education; the possibility of direction change of professional preparation in case of detection of discrepancy of qualities of the pupil to originally selected profile is provided. Career-oriented activity in developing countries, on the contrary, is rigidly coordinated to requirements of economy and a labour market

  5. The pentomic experience

    The Pentomic experience is presented in outline form. The subject is discussed under the following topics: context, objectives, description, assessment, and lessons. The context included President Eisenhower's open-quotes new lookclose quotes strategy and service rivalry for nuclear share. The objectives for the Pentomic Division included dual capability with nuclear emphasis, strategic mobility, smaller, and major organizational changes. The Pentomic Division is described as a separate division in which the infantry battle group is a basic building block. The Pentomic Division was designed to be dual-capable in both conventional and nuclear warfare and was assessed or perceived to be neither. The possible reasons for the failure of the concept were: problem too hard, wrong solution, premature solution, weak implementation, and overambitious goals

  6. Experience with Kamini reactor

    Kamini is a 233U fuelled, 30 kW(th) research reactor. It is one of the best neutron source facility with a core average flux of 1012 n/cm2/s in IGCAR used for neutron radiography of active and nonradioactive objects, activation analysis and radiation physics research. The core consists of nine plate type fuel elements with a total fuel inventory of 590 g of 233U. Two safety control plates made of cadmium are used for start up and shutdown of the reactor. Three beam tubes, two-thimble irradiation site outside reflector and one irradiation site nearer to the core constitute the testing facilities of Kamini. Kamini attained first criticality on 29th October 96 and nominal power of 30 kW in September 1997. This paper covers the design features of the reactor, irradiation facilities and their utilities and operating experience of the reactor. (author)

  7. Direct Neutrino Mass Experiments

    Mertens, Susanne

    2016-01-01

    With a mass at least six orders of magnitudes smaller than the mass of an electron -- but non-zero -- neutrinos are a clear misfit in the Standard Model of Particle Physics. On the one hand, its tiny mass makes the neutrino one of the most interesting particles, one that might hold the key to physics beyond the Standard Model. On the other hand this minute mass leads to great challenges in its experimental determination. Three approaches are currently pursued: An indirect neutrino mass determination via cosmological observables, the search for neutrinoless double $\\beta$-decay, and a direct measurement based on the kinematics of single $\\beta$-decay. In this paper the latter will be discussed in detail and the status and scientific reach of the current and near-future experiments will be presented.

  8. The PODS diversity experiment

    A high integrity system typically has a number of redundant components operating in parallel to reduce the probability of a system failure. If the component failures were random, then the probability of several components failing simultaneously would be much smaller than the failure probability of any single component. However, should the components contain common design flaws, then more than one component could fail simultaneously due to a common cause (a common mode failure). This would increase the probability of a system failure. For a computer-based system where the same software component is being run in each processor, any software fault is a potential cause of common mode failure. One method of reducing common software faults is to use diverse software in each processor (n-version programming). This paper discusses how the use of software diversity raises a number of issues. A diversity experiment is described

  9. CBM Experiment at FAIR

    The Compressed Baryonic Matter (CBM) project at the future accelerator center FAIR will be a dedicated heavy-ion experimental operating in fixed target mode at beam energies from 8 to 45 AGeV. The ultimate goal of the research program is to explore the QCD phase diagram in the range of moderate temperature but the highest net-baryon densities. The CBM detector concept aims to obtain feasibility of measurement of hadronic, leptonic and photonic observables at interaction rates up to 10 MHz. It will allow to detect extremely rare probes such as charm near its production threshold. The CBM experiment will enter a new era with diagnostic probes never accessible before in the FAIR energy range, and thus has a unique research potential. (author)

  10. INITIAL COOLING EXPERIMENT (ICE)

    1979-01-01

    ICE was built in 1977, using the modified bending magnets of the g-2 muon storage ring (see 7405430). Its purpose was to verify the validity of stochastic and electron cooling for the antiproton project. Stochastic cooling proved a resounding success early in 1978 and the antiproton project could go ahead, now entirely based on stochastic cooling. Electron cooling was experimented with in 1979. The 26 kV equipment is housed in the cage to the left of the picture, adjacent to the "e-cooler" located in a straight section of the ring. With some modifications, the cooler was later transplanted into LEAR (Low Energy Antiproton Ring) and then, with further modifications, into the AD (Antiproton Decelerator), where it cools antiprotons to this day (2006).

  11. Baryon conservation (experiments)

    Proton decay as a generic term is here defined to include the decay of neutrons which have been stabilized against BETA-decay by nuclear binding. A history of proton stability is thus presented by means of a an annotated chronolgy and tables based on questionnaries. The latter supplied by research groups planning proton lifetime experiments outside the USA. Each of seven tables present location, depth, weight of detector, method of detection, Partial Lifetime Limits Obtainable, and Present Status and/or Time when (Preliminary) Results are Expected from each of the collaborative institutions. The latter include Frascati-Milano-Torino, Frascati-Milano-Rome-Torino, Orsay-Ecole Polytechnique-Saclay, Torino-Moscow-Frascati, Bombay-Osaka-Tokyo, and two locations reported on by the Institute for Nuclear Research of the Academy of Sciences of the USSR. Survey reports on other institutions are also given, imcluding universities

  12. Tritium neutrino mass experiments

    The current status of the experimental search for neutrino mass is reviewed, with emphasis on direct kinematic methods, such as the beta decay of tritium. The situation concerning the electron neutrino mass as measured in tritium beta decay is essentially unchanged from a year ago, although a great deal of experimental work is in progress. The ITEP group continues to find evidence for a nonzero mass, now slightly revised to 26(5) eV. After correcting for recently discovered errors in the energy loss distribution and source thickness, however, the Z/umlt u/rich group still claims and upper limit of 18 eV. There may be evidence for neutrino mass and mixing in the SN1987a data, in the same range suggested by the ITEP experiment. 42 refs., 3 figs

  13. The Digital Archive Experience

    Søndergaard, Morten

    2009-01-01

    This article, as well as the book, investigates the ways in which new digital media may enhance the experience of the art-archive. Taken as a whole, the new media is a vital component of a 'transdisciplinary' and transformative field, a cultural landscape that is changing rapidly the conditions...... and domains of the archive and the (art)museum. How, then, should the functions and strengths of both archive and museum be shaped to meet those cultural and technological changes? When the Internet and world wide web became 'the place to be' commercially, museums followed suit and established their own sites....... The book discusses the challenges of the archive and the (art)museum in the age of digital media. It is based upon documentation from a research project, MAP - Media Art Platform, that drew upon the talents and collaboration of many institutions, artists, programmers, art historians, designers and others...

  14. The 'DANTE' experiment

    Freeman, Ray; Morris, Gareth A.

    2011-12-01

    The selective excitation scheme known as 'DANTE' emerged from a confluence of several ideas for new NMR experiments, some more fanciful than others. DANTE offers a simple and effective way to restrict excitation to a very narrow frequency band, usually that of a single resonance line. Initially applied to the study of individual proton-coupled carbon-13 spin multiplets, the method has been extended to water presaturation, relaxation measurements, and chemical exchange studies. Through the imposition of a magnetic field gradient it offers a simple method to enhance resolution by restricting the effective volume of the sample. Multiple DANTE excitation (with Hadamard encoding) can speed up multidimensional spectroscopy by orders of magnitude. Applied to magnetic resonance imaging, the DANTE sequence has been used to superimpose a rectangular grid onto a cardiac image, permitting motional distortions to be monitored in real time.

  15. A European experiment

    The Joint European Torus (JET) is an experiment in nuclear fusion research which was planned as a joint effort between national research laboratories and Euratom. Before approval was given for it to be built it became a political football in the European Communities. This book describes the background against which JET was conceived, designed and planned. It gives a chronological account of the political imbroglio which followed between 1975 and 1978 and indicates how close the project came to collapse at one point. In addition to the two years' delay caused by Ministerial conflicts over its siting, the project suffered many compromises in its financing, its staffing and its organisation. An account is given of the unique structure of the European Communities and its procedures, which shows how idealism constantly faces reality. The role of Euratom is discussed, taking into account the difference between its approach to applications of nuclear fission as opposed to those of nuclear fusion. (author)

  16. The SNO+ Experiment

    Chen, Mark C

    2008-01-01

    The SNO+ experiment is the follow-up to the Sudbury Neutrino Observatory (SNO). The heavy water that was in SNO will be replaced with a liquid scintillator of linear alkylbenzene (plus fluor). SNO+ has many physics goals including detecting pep and CNO solar neutrinos, detecting geo-neutrinos, studying reactor neutrino oscillations, serving as a supernova neutrino detector and carrying out a search for neutrinoless double beta decay by adding neodymium to the liquid scintillator. Since a large amount of 150Nd isotope can be added to SNO+, a competitive search would be possible, with sensitivity below 100 meV using natural Nd and sensitivity below 40 meV with enriched neodymium.

    The Cibola Flight Experiment (CFE) is an experimental small satellite carrying a reconfigurable processing instrument developed at the Los Alamos National Laboratory that demonstrates the feasibility of using FPGA-based high-performance computing for sensor processing in the space environment. The CFE satellite was launched on March 8, 2007 in low-earth orbit and has operated extremely well since its deployment. The nine Xilinx Virtex FPGAs used in the payload have been used for several high-throughput sensor processing applications and for single-event upset (SEU) monitoring and mitigation. This paper will describe the CFE system and summarize its operational results. In addition, this paper will describe the results from several SEU detection circuits that were performed on the spacecraft.

  18. The VIP experiment

    The VIP (Violation of the Pauli Exclusion Principle) experiment is dedicated to check the validity of one of the basic principles of modern physics. This investigation is done searching for anomalous X-rays emitted by copper atoms in a conductor: any detection of these anomalous X-rays would mark a Pauli forbidden transition. VIP is currently taking data at the Gran Saso underground laboratories, and its scientific goal is to improve by three-four orders of magnitude the previous limit on the probability of Pauli violating transitions, bringing it into the 10-29 to -30 region. The new experimental results and future plans are presented. The PDF file for this article was corrected and the names and affiliations were amended on 4 September 2009.

  20. Design of Computer Experiments

    Dehlendorff, Christian

    The main topic of this thesis is design and analysis of computer and simulation experiments and is dealt with in six papers and a summary report. Simulation and computer models have in recent years received increasingly more attention due to their increasing complexity and usability. Software...... packages make the development of rather complicated computer models using predefined building blocks possible. This implies that the range of phenomenas that are analyzed by means of a computer model has expanded significantly. As the complexity grows so does the need for efficient experimental designs...... and analysis methods, since the complex computer models often are expensive to use in terms of computer time. The choice of performance parameter is an important part of the analysis of computer and simulation models and Paper A introduces a new statistic for waiting times in health care units. The statistic...

  1. Laterality and language experience.

    Hull, Rachel; Vaid, Jyotsna

    2006-09-01

    A meta-analysis was conducted on studies that examined hemispheric functional asymmetry for language in brain-intact monolingual and bilingual adults. Data from 23 laterality studies that directly compared bilingual and monolingual speakers on the same language were analysed (n = 1234). Variables examined were language experience (monolingual, bilingual), experimental paradigm (dichotic listening, visual hemifield presentation, and dual task) and, among bilinguals, the influence of second language proficiency (proficient vs nonproficient) and onset of bilingualism (early, or before age 6; and late, or after age 6). Overall, monolinguals and late bilinguals showed reliable left hemisphere dominance, while early bilinguals showed reliable bilateral hemispheric involvement. Within bilinguals, there was no reliable effect of language proficiency when age of L2 acquisition was controlled. The findings indicate that early learning of one vs. two languages predicts divergent patterns of cerebral language lateralisation in adulthood. PMID:16882556

NA49 is one of the seven experiments (NA44, NA45, NA49, NA50, NA52, WA97/NA57 and WA98) involved in CERN's Heavy Ion programme which provided evidence for the existence of a new state of matte, the quark-gluon plasma. In this state, quarks, instead of being bound up into more complex particles such as protons and neutrons, are liberated and roam freely. Theory predicts that this state must have existed at about 10 microseconds after the Big Bang, before the formation of matter as we know it today.

    The determination of the neutrino mass is an open issue in modern particle physics and astrophysics. The direct mass measurement is the only theory-unrelated experimental tool capable to probe such quantity. The HOLMES experiment will measure the end-point energy of the electron capture decay of ^{163}Ho, aiming at a statistical sensitivity on the neutrino mass around 1 eV/c^2. In order to acquire the large needed statistics by keeping the pile-up contribution as low as possible, 1000 transition edge sensors will be readout simultaneously with the frequency domain readout, a multiplexing technique where the multiplex factor is only limited by the bandwidth of the available commercial fast digitizers. We outline here the HOLMES project with its technical challenges, and its status and perspectives.

    Murphy, Hugh D. [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    1984-03-26

    Experiment 2032 was conductin in two stages. The first stage, the so-called pre-pump, was an initial test of the packer installed at 3.46 km (11,340 feet) in the EE-2 well which was conducted on November 30, 1983. A total volume of 360m³ (95,000 gallons) was injected at pumping pressures up to 41 MPa (6000 psi). In the 2nd stage, December 6-9, about 21,000 m³ (5.6 million gallons) of water were injected in well EE-2, at surface pumping pressures up to 48 MPa (7000 psi) and injection rates as high as 0.11 m³/sec (43 bmp) in an attempt to hydraulically fracture the rock between wells EE-2 and EE-3 to create a low impedance flow connection.

  5. Column and Batch Experiments

    Jorge L. Gardea-Torresdey

    2005-01-01

    Full Text Available Batch and column experiments were performed to determine the Cu(II binding capacity of silica-immobilized humin biomass. For column studies, 500 bed volumes of a 0.1 mM Cu(II solution were passed through humin packed columns at the flow rates of 1, 1.5, 2, and 3 mL/min. The biopolymer showed an average Cu binding capacity of 12 ± 1.5 mg/g and a Cu recovery of about 96.5 % ± 1.5. The breakthrough points for Cu(II alone were approximately 420, 390, 385, and 300 bed volumes for the flow rates of 1, 1.5, 2 and 3 mL/min, respectively. The interference studies demonstrated that at low concentrations, the hard cations Ca(II and Mg(II did not seem to represent a major interference on Cu(II binding to the humin biopolymer. The selectivity showed by this biopolymer was Cu(II>Ca(II>Mg(II. On the other hand, batch experiments showed that Ca(II + Mg(II at 100mM each reduced the Cu(II binding to 73 %. However, 1000 mM concentrations of Ca(II and Mg(II, separately and in mixture, reduced the Cu(II binding to 47 %, 44 % and 31 %, respectively. The results of this study showed that immobilized humin in a silica matrix could represent an inexpensive bio-source for Cu removal from contaminated water, even in the presence of low concentrations of the hard cations Ca(II and Mg(II.

  9. SPRUCE experiment data infrastructure

    Krassovski, M.; Hanson, P. J.; Boden, T.; Riggs, J.; Nettles, W. R.; Hook, L. A.

    2013-12-01

    The Carbon Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory (ORNL), USA has provided scientific data management support for the US Department of Energy and international climate change science since 1982. Among the many data activities CDIAC performs are design and implementation of the data systems. One current example is the data system and network for SPRUCE experiment. The SPRUCE experiment (http://mnspruce.ornl.gov) is the primary component of the Terrestrial Ecosystem Science Scientific Focus Area of ORNL's Climate Change Program, focused on terrestrial ecosystems and the mechanisms that underlie their responses to climatic change. The experimental work is to be conducted in a bog forest in northern Minnesota, 40 km north of Grand Rapids, in the USDA Forest Service Marcell Experimental Forest (MEF). The site is located at the southern margin of the boreal peatland forest. Experimental work in the 8.1-ha S1 bog will be a climate change manipulation focusing on the combined responses to multiple levels of warming at ambient or elevated CO2 (eCO2) levels. The experiment provides a platform for testing mechanisms controlling the vulnerability of organisms, biogeochemical processes and ecosystems to climatic change (e.g., thresholds for organism decline or mortality, limitations to regeneration, biogeochemical limitations to productivity, the cycling and release of CO2 and CH4 to the atmosphere). The manipulation will evaluate the response of the existing biological communities to a range of warming levels from ambient to +9°C, provided via large, modified open-top chambers. The ambient and +9°C warming treatments will also be conducted at eCO2 (in the range of 800 to 900 ppm). Both direct and indirect effects of these experimental perturbations will be analyzed to develop and refine models needed for full Earth system analyses. SPRUCE provides wide range continuous and discrete measurements. To successfully manage SPRUCE data flow

  11. When an experiment is crucial?

    Pleitez, V.

    1998-01-01

    Although we accept that Physics is, as a last resort, an experimental science, the relationship between theory and experiment is far away from being trivial. Any experiment is always explained within a determinate theoretical context and, at the same time, an experiment can give suggestions for theories or even can bring new theoretical challenges. Thus, we cannot say without ambiguity when an experiment is a crucial one.

  15. The Nepal experience.

    Kaikobad, N F

    1977-01-01

    Nepal's panchayat system of partyless democracy with 5 class organizations of peasants, youth, women, labor, and ex-servicemen, is an effort in community development. Panchayat training centers train panchayat secretaries and women workers. The government tried out the Mobile Training Scheme (MTS) methodology to train panchayat training center instructors in 1974-75 when 5 courses were given for 76 participants. The MTS methodology included several new assumptions: the necessity of knowing the field situation, a realistic problem solving orientation, learning by actual field experience, and interdependence rather than teacher dependence. The multipurpose role of the panchayat secretary was studied and clarified. Role performance led to the development of a realistic job description from which a task-focused curriculum could be developed. Field work tools included maintaining a daily diary, collecting information and developing a present and past project history, and compiling a village profile. The trainees played the roles of front line workers in the field when they returned from the villages played the roles of supervisors and trainers. The key concept in the multipurpose role of the panchayat secretary was collaboration. The panchayat secretary-trainee had to understand the social roles in the community, and work within the social context to get cooperation from other agencies, village and informal organizations, in order to fulfill their role. Tutorial and team teaching methods were used to provide partnership in learning; the old roles of lecturer and lectured were seen as ineffective when actual field experience was the criteria. The role performing and role analysis group analyzed the front line workers' roles and evolved job descriptions which led to course outlines. The teaching methods and materials group produced indigenous teaching materials for classroom use based on problems faced in the field. The action research and technical collaboration groups

  16. THE EXPERIENCE OF ART – THE EMPIRIA OR EXPERIMENT?

    Franciszek Chmielowski

    2010-01-01

    Full Text Available In contemporary aesthetics exists an belief, that the experience of art is the primary fact, which initiates and leads theoretical reflection, as also is the state basis of creating, valuing and the opinion on art. Present text is the test of philosophical recognition of relationship between field of products of new art as well as with context formative it experiences. Author motivates thesis, that radical changes in present art have their source in of meanings consisting on primary notion of experience changes. The present artistic practice goes away from aesthetical experience as empiria and the contemplation and used the notion of experience as experiment and investigation, which dismisses art from her proper functions and brings it rather to aggressive ideology of scientism. The recognition of this progressive change of meanings in founding the art notion of experience has the important consequences both for understanding of present art and for describing it theory.

  2. DSM - the Iowa experience

    The Iowa Legislature passed a landmark bill in the 1990 session which became effective July 1, 1990. This legislation had several components, the most significant being a requirement for rate-regulated utilities in Iowa to begin implementing energy efficiency program. The legislation sets spending targets of 2% of gross electric revenues and 1 1/2% of gross gas revenues. It also requires five specific program areas to be considered. Administrative rule making to comply with the legislation was completed in early 1991 and all utility plans were filed by July 1, 1991. The plans were reviewed in individual contested proceedings and most were approved by February 1, 1992. The final orders in all of the proceedings required the utilities to begin the programs in 1992. Iowa-Illinois Gas and Electric Company proposed and received approval on eight programs spanning all customer classes. Most of the programs include both gas and electric measures. The four residential programs were implemented on March 1, 1992 and the four commercial/industrial programs were implemented on April 1, 1992. Costs of the programs are deferred in special accounts until a contested cost recovery proceeding is convened. The legislation requires cost recovery from customers to lag the program implementation by at least two years. Therefore, those proceedings will commence in 1994 with amortization to be spread over four years following an order in that proceeding. The presentation will follow the sequence of the following charts as well as detail experience in the programs to date

  3. Particle physics experiments, 1991

    Data taking for this experiment was completed in December 1983. The samples include approximately 19,000 (ν) and 11,000 (ν-bar) charged current events. These constitute the largest data set of interactions on free protons. Work published to date includes studies of inclusive structure functions and final state properties, exclusive final states, neutral current cross sections and production of strange and charmed particles. During the past year results have been published on the production of f2 (1270) and ν0 (770) mesons in ρp and ρ-barp charged current interactions. In the case of the f2 this represents the first observation of such production. It is found that the multiplicities are 0.047±0.017 in ρp and 0.17±0.018 in ρ-barp. The f2 mesons are mostly produced at large hadronic invariant mass W and in the forward hemisphere. The production of ν0 mesons can be observed with high statistics in both ρp and ρ-barp interactions and the differential cross section studied. The observations are compared with LUND Monte Carlo predictions, which are generally found to be too high. However qualitative features of the data are reproduced. Work continues on a precise determination of the neutral current/charged current ratio, on the study of charged and neutral current structure functions and on the production of strange particles.

  4. VISIR: Experiences and Challenges

    Mohamed Tawfik

    2012-02-01

    Full Text Available It is of crucial importance the integration of practical sessions in engineering curricula owing to their significant role in understanding engineering concepts and scientific phenomena. However, the lack of practical sessions due to the high costs of the equipment and the unavailability of instructors has caused a significant declination in experimentation in engineering education. Remote laboratories have tackled this issues providing online reusable and shared workbenches unconstrained by neither geographical nor time considerations. Thereby, they have extremely proliferated among universities and integrated into engineering curricula over the last decade. This contribution compiles diverse experiences based on the deployment of the remote laboratory, Virtual Instrument Systems in Reality (VISIR, on the practices of undergraduate engineering grades at various universities within the VISIR community. It aims to show the impact of its usage on engineering education concerning the assessments of students and teachers as well. In addition, the paper address the next challenges and future works carried out at several universities within the VISIR community.

  5. Single-nucleon experiments

    Deur, Alexandre

    2009-12-01

    We discuss the Jefferson Lab low momentum transfer data on moments of the nucleon spin structure functions $g_1$ and $g_2$ and on single charged pion electroproduction off polarized proton and polarized neutron. A wealth of data is now available, while more is being analyzed or expected to be taken in the upcoming years. Given the low momentum transfer selected by the experiments, these data can be compared to calculations from Chiral Perturbation theory, the effective theory of strong force that should describe it at low momentum transfer. The data on various moments and the respective calculations do not consistently agree. In particular, experimental data for higher moments disagree with the calculations.The absence of contribution from the $\\Delta$ resonance in the various observables was expected to facilitate the calculations and hence make the theory predictions either more robust or valid over a larger $Q^2$ range. Such expectation is verified only for the Bjorken sum, but not for other observables in which the $\\Delta$ is suppressed. Preliminary results on pion electroproduction off polarized nucleons are also presented and compared to phenomenological models for which contributions from different resonances are varied. Chiral Perturbation calculations of these observables, while not yet available, would be valuable and, together with these data, would provide an extensive test of the effective theory.

  6. Experiments with Superheavy Nuclei

    Hofmann, S.

    1999-03-01

    In two series of experiments at SHIP, six new elements (Z=107-112) were synthesized via fusion reactions using lead or bismuth targets and 1n-deexcitation channels. The isotopes were unambiguously identified by means of α -α correlations. Not fission, but alpha decay is the dominant decay mode. Cross-sections decrease by two orders of magnitude from bohrium (Z=107) to element 112, for which a cross-section of 1 pb was measured. Based on these results, it is likely that the production of isotopes of element 114 close to the island of spherical SuperHeavy Elements (SHE) could be achieved by fusion reactions using 208Pb targets. Systematic studies of the reaction cross-sections indicate that the transfer of nucleons is an important process for the initiation of fusion. The data allow for the fixing of a narrow energy window for the production of SHE using 1n-emission channels. The likelihood of broadening the energy window by investigation of radiative capture reactions, use of neutron deficient projectile isotopes and use of actinide targets is discussed.

  9. Phishing: A Field Experiment

    Danuvasin Charoen, Ph.D.

    2011-05-01

    Full Text Available Phishing is a method that hackers use to fraudulently acquire sensitive or private information from a victimby impersonating a real entity [1]. Phishing can be defined as the act of soliciting or stealing sensitiveinformation such as usernames, passwords, bank account numbers, credit card numbers, and socialsecurity or citizen ID numbers from individuals using the Internet [2]. Phishing often involves some kindof deception. The results from a study of Jagatic et al. (2007 indicate that Internet users are four timesmore likely to become phishing victims if they receive a request from someone appearing to be a knownfriend or colleague. The Anti-Phishing Work Group indicates that at least five percent of users respondedto phishing scams and about two million users gave away their information to spoofed websites [3]. Thisresults in direct losses of $1.2 billion for banks and credit card companies (Dhamija, 2006.In order to understand how phishing can be conducted, the researcher set up a phishing experiment inone of Thailand’s higher education institutions. The subjects were MBA students. A phishing email wassent to the subjects, and the message led the subject to visit the phishing website. One hundred seventystudents became victims. The data collection included a survey, an interview, and a focus group. Theresults indicated that phishing could be easily conducted, and the result can have a great impact on thesecurity of an organization. Organizations can use and apply the lessons learned from this study toformulate an effective security policy and security awareness training programs.

  10. Cyclotron trap: future experiments

    The cyclotron trap at PSI was built to increase the brightness of a source of x-rays emitted from exotic atoms. It allows to work at target densities where the interaction with the surrounding atoms is substantially reduced. Especially electron refilling can be excluded for medium to low Z atoms, which results in a high or even complete ionization. X-rays emitted from higher n-states of electron-free exotic atoms have well defined energies with the error originating only from the error in the mass values of the constituent particles. In consequence an experiment for a new determination of the pion mass was performed using a high resolution crystal spectrometer. The determination of the response function of the spectrometer could be performed using x-rays from completely ionized pionic carbon and with a dedicated electron cyclotron resonance ion trap (ECRIT). A further extension of the ECRIT method allows a direct calibration of exotic atom transitions as well as a precise determination of the energy of fluorescence lines. In combination an increase in accuracy of one order of magnitude can be achieved and a dense set of x-ray energy standards below 20 keV can be established. (author)

  11. Subterranean stress engineering experiments

    The state of stress in a subterranean rock mass has classically been assumed to be constant at best. In soil with a high clay content, preconsolidation and drainage methods can lead to more stable foundation material, but methods for engineering the stresses in large masses of rock are not well known. This paper shows the results from an experiment designed to alter the in situ rock stress field in an oil shale mine. This was done by hydrofracturing the rock by use of a packed-well injection system and then propping the crack open with a thixotropic gel, which slowly hardened to the consistency of cement. Successive hydrofracture and high-pressure grouting resulted in an overstressed region. Well-head injection pressures, surface tilts, injection rates, and subterranean strains were measured and recorded on floppy disk by a Z-80 microprocessor. The results were then transmitted to the large computer system at the Los Alamos Scientific Laboratory (LASL). To put the data in a more useful form, computer-generated movies of the tilts and strains were made by use of computer graphics developed at LASL. The purpose of this paper is to present results from the Single Large Instrumented Test conducted in the Colony Oil Shale Mine near Rifle, Colorado. 13 figures

  12. Experiments with particle damping

    Hollkamp, Joseph J.; Gordon, Robert W.

    1998-06-01

    High cycle fatigue in jet engines is a current military concern. The vibratory stresses that cause fatigue can be reduced by adding damping. However, the high temperatures that occur in the gas turbine greatly hinder the application of mature damping technologies. One technology which may perform in the harsh environment is particle damping. Particle damping involves placing metallic or ceramic particles inside structural cavities. As the cavity vibrates, energy is dissipated through particle collisions. Performance is influenced by many parameters including the type, shape, and size of the particles; the amount of free volume for the particles to move in; density of the particles; and the level of vibration. This paper presents results from a series of experiments designed to gain an appreciation of the important parameters. The experimental setup consists of a cantilever beam with drilled holes. These holes are partially filled with particles. The types of particles, location of the particles, fill level, and other parameters are varied. Damping is estimated for each configuration. Trends in the results are studied to determine the influence of the varied parameter.

  13. Use experience of FLUKA

    1998-03-01

    In order to conduct the shield design calculation of the Large Hadron Collider (LHC) under planning in CERN at present, the radiation group of CERN uses FLUKA (Monte Carlo High Energy Radiation Transport Code). Here is introduced on outline of FLUKA and use experience of FLUKA in the LHC-B detector shield design calculation in LHC plan. FLUKA can be said to be the highest standard in the high energy radiation transportation code of the world at every points of the physical model, the Monte Carlo calculation technique and the convenience at usage of the code. In Japan Atomic Energy Research Institute (JAERI), a using right of FLUKA for the target neutronics and facility shielding design at the neutron science research center is obtained and it seems to be an effective design means in these future designs. However, because FLUKA is allowed a limited opening and no own verification on the code, it will be supposed to be a large problem on investigating a validity in design. (K.G.)

  14. Gathering positive experience

    2009-01-01

    Last Monday, the new CERN Machine Advisory Committee (CMAC) met for the first time, and we had good news to tell its members. Over the weekend, injection tests for both LHC beams were successfully carried out. In other words, we’ve had beam in the LHC for the first time since September 2008. That’s a good feeling, but it’s no reason for complacency. There’s still a long way to go before first physics at the new energy frontier. As the Bulletin has reported over recent weeks, we’re gathering a lot of positive experience with the new quench detection and protection system (QPS), which is already allowing us to monitor the LHC far better than we were able to in the past. So far, the QPS for three of the LHC’s eight sectors has been put through its paces, and we’ve also power tested those sectors to 2000 amperes, the equivalent of around 1.2 TeV per beam. The next step is to slowly increase the current to 4000 amperes, and...

  15. Results from LHCf Experiment

    Tricomi Alessia

    2012-06-01

    Full Text Available The LHCf experiment has taken data in 2009 and 2010 p-p collisions at LHC at √s = 0.9 TeV and √s = 7 TeV. The measurement of the forward neutral particle spectra produced in proton-proton collisions at LHC up to an energy of 14 TeV in the center of mass system are of fundamental importance to calibrate the Monte Carlo models widely used in the high energy cosmic ray (HECR field, up to an equivalent laboratory energy of the order of 1017 eV. In this paper the first results on the inclusive photon spectrum measured by LHCf is reported. Comparison of this spectrum with the model expectations show significant discrepancies, mainly in the high energy region. In addition, perspectives for future analyses as well as the program for the next data taking period, in particular the possibility to take data in p-Pb collisions, will be discussed.

  16. Biofuels: The African experience

    Carrillo, L.A.; Nkolo, M. [German Agency for Technical Cooperation GTZ, Delegation Regionale des Eaux et Forets, Bertoua (Cameroon)

    2009-07-01

    In July 2006, the African Non-Petroleum Producers Association was formed in Senegal, Africa to develop alternative energy sources. It involved 13 of Africa's poorest nations, who joined forces to become global suppliers of biofuels, and some have set mandatory mixing of ethanol into gasoline. Although several biofuel production projects have been launched in western Africa, many of the new projects and plantations have not yet reached maturity due to the time lag between plantation and full-scale production, which is about 6 years. Major projects that could be producing significant quantities of biofuels in the next few years are not yet reflected in production statistics. Although ethanol is not yet being produced in large quantities in Africa, short-term opportunities exist. Countries in the South African Development Community are using molasses from the sugar can industry to produce ethanol. Biodiesel is also not currently produced on a significant scale in western Africa, but several other countries are gaining experience with cotton and palm oil resources, and Jatropha. Biomass residue also represents a large potential for all African countries involved in timber production. Unlike biodiesel production, land use conflicts are not an issue with biomass residue production.

  17. REBEKA bundle experiments

    This report is a summary of experimental investigations describing the fuel rod behavior in the refilling and reflooding phase of a loss-of-coolant accident of a PWR. The experiments were performed with 5x5 and 7x7 rod bundles, using indirectly electrically heated fuel rod simulators of full length with original PWR-KWU-geometry, original grid spacers and Zircaloy-4-claddings (Type Biblis B). The fuel rod simulators showed a cosine shaped axial power profile in 7 steps and continuous, respectively. The results describe the influence of the different parameters such as bundle size on the maximum coolant channel blockage, that of the cooling on the size of the circumferential strain of the cladding (azimuthal temperature distribution) a cold control rod guide thimble and the flow direction (axial temperature distribution) on the resulting coolant channel blockage. The rewetting behavior of different fuel rod simulators including ballooned and burst Zircaloy claddings is discussed as well as the influence of thermocouples on the cladding temperature history and the rewetting behavior. All results prove the coolability of a PWR in the case of a LOCA. Therefore, it can be concluded that the ECC-criteria established by licensing authorities can be fulfilled. (orig./HP)

  18. An outreach experience

    Naze, Y.

    In our technological world, Science is everywhere and to participate to the public debates, citizens will need some basic scientific notions. Raising awareness of the public in Science is thus always worthwhile, even though only a small fraction of the audience will envisage a career in the field. Bringing science to the layman should even be a duty for scientists: we should not forget that we are paid by taxpayers, and are part of a public service; and besides, people tend to reject things that they do not understand - to get support, scientists need to enter the public arena and confront the crowd. Relying on attractive images and a timeless fascination, astronomy is particularly suited to do that. But what should a willing astronomer do to share (his/her) knowledge? There is certainly no definitive answer for that, but a few hints can still be given. Based on personal experience, this talk will present a few tips and things to avoid in three cases: animations (for kids and grown-ups), writing, and talking.

  19. The CAPTAIN Experiment

    Bian, Jianming

    2015-01-01

    The Cryogenic Apparatus for Precision Tests of Argon Interactions with Neutrinos (CAPTAIN) program is designed to make measurements of scientific importance to long-baseline neutrino physics and physics topics that will be explored by large underground detectors. The experiment employs two liquid Argon time projection chambers (LArTPCs), a primary detector with a mass of approximately 10 ton that will be deployed at different facilities for physics measurements and a two ton prototype detector for configuration testing. The physics programs for CAPTAIN include measuring neutron interactions at the Los Alamos Neutron Science Center, measuring neutrino interactions in the high-energy regime (1.5-5 GeV) at Fermilab NuMI beam, and measuring neutrino interactions in the low-energy regime (<50 MeV) at stopped pion sources for supernova neutrino studies. The prototype detector (Mini-CAPTAIN) has been commissioned and the first UV laser track has been seen in its TPC. This paper gives an overview of the CAPTAIN pr...

  20. Khibiny experiment described

    Velikhov, Y. P.; Zhamaletdinov, A. A.; Zhdanov, M. S.

    1984-12-01

    On the Kola Peninsula a power pulsed magnethodynamic generator is being used in probing for up to tens of kilometers into the depths of an enormous territory. This experiment encompasses an experimental test area where tests of new equipment and the new technology of deep electromagnetic soundings are being carried out. In the arsenal of geophysical methods for studing the Earth's deep layers, in addition to seismic and gravimetric methods, an important place is occupied by electromagnetic methods. The essence of these methods is that the primary (external) electromagnetic field induces electrical currents in the earth's conducting layers which generate a secondary (internal) field. Special sensors at the surface register the total effect of these two fields. The electrical currents induced in the Earth, and accordingly, the secondary field, are dependent on the distribution of conductivity in the Earth. Thus, on the basis of electromagnetic measurements at the Earth's surface it is possible to determine conductivity in the Earth's deep layers and it can give information on the thermodynamic and phase states of rocks at great depths. The apparatus and results of the geophysical probes are discussed.

  1. A moving experience !

    2005-01-01

    The Transport Service pulled out all the stops and, more specifically, its fleet of moving and lifting equipment for the Discovery Monday on 6 June - a truly moving experience for all the visitors who took part ! Visitors could play at being machine operator, twiddling the controls of a lift truck fitted with a jib to lift a dummy magnet into a wooden mock-up of a beam-line.They had to show even greater dexterity for this game of lucky dip...CERN-style.Those with a head for heights took to the skies 20 m above ground in a telescopic boom lift.Children were allowed to climb up into the operator's cabin - this is one of the cranes used to move the LHC magnets around. Warm thanks to all members of the Transport Service for their participation, especially B. Goicoechea, T. Ilkei, R. Bihery, S. Prodon, S. Pelletier, Y. Bernard, A.  Sallot, B. Pigeard, S. Guinchard, B. Bulot, J. Berrez, Y. Grandjean, A. Bouakkaz, M. Bois, F. Stach, T. Mazzarino and S. Fumey.

    %RE4 %title\\\\ \\\\The L3+C experiment takes advantage of the unique properties of the L3 muon spectrometer to get an accurate measurement of cosmic ray muons 30 m underground. A new muon trigger, readout and DAQ system have been installed, as well as a scintillator array covering the upper surfaces of the L3 magnet for timing purposes. The acceptance amounts to 200 $m^2 sr$. The data are collected independently in parallel with L3 running.

These data will also hel...

  3. rf experiments on PLT

    A variety of rf experiments are being conducted on PLT in order to explore rf techniques which could improve tokamak performance parameters. Of special importance are the studies of ion Bernstein wave (IBW) heating, lower hybrid MHD stabilization and electron heating, down-shifted electron cyclotron heating, and fast wave current drive. Ion Bernstein wave heating results at modest power indicate that the particle confinement time could be enhanced relative to that for fast wave heating in the ion cyclotron range of frequencies (ICRF) and neutral beam heating. At these power levels a conclusive determination of energy confinement scaling with power cannot yet be given. Central sawtooth and m = 1 MHD stabilization is being obtained with centrally peaked lower hybrid (LH) current drive and the central electron temperature is peaking to values (approx.5 keV) well outside the bounds of ''profile consistency.'' In this case the electron energy confinement is apparently increased relative to the ohmic value. The production of relativistic electrons via heating at the down-shifted electron cyclotron (EC) frequency is found to be consistent with theoretical predictions and lends support to the use of this method for heating in relatively high magnetic field devices

  4. Chamera: A Himalayan experience

    The 540 MW Chamera hydroelectric project is located on the Ravi River in the foothills of the Himalayas 500 km north of Delhi. The Chamera Constructors Consortium is made up of a joint venture of SNC Inc., Acres International, Marine Industries Limited and General Electric Canada. The consortium provides engineering, procurement, and construction management services, and supplies turbines and gates, generators and associated electrical equipment. The experience of the consortium in dealing with the Indian Government is detailed. A multi-envelope bidding system was used, with the lowest cost, technically acceptable bid receiving the contract. Misunderstandings can arise due to different perceptions of the bidding process between Canadian companies and the National Hydroelectric Power Corporation (NHPC) of the Indian government, with NHPC taking a more formal approach in contractual dealings. Export paperwork was frequently in error leading to delays in passage of goods through Indian customs. With the liberalization of the Indian trade laws there is a potential for Canada to supply a significant quantity of equipment for India's planned 38,000 MW of hydroelectric expansion. 11 figs., 2 tabs

  5. Enthusiastic Teachers, Vivid Experiments

    Moore, John W.

    2000-04-01

    ascination with materials and chemical change is a hallmark of chemists, and it is also an important pedagogical tool. A fringe benefit of editing JCE is that I encounter so many nice people who send interesting and helpful communications. One of the first of these to cross my desk this year was from E. J. Behrman, who recommended that I read and call to your attention "Brilliant Light: A Chemical Boyhood" by Oliver Sacks, noted neurologist and author. It appeared in the December 20, 1999, issue of The New Yorker and is well worth your time and effort to find and read. Sacks's reminiscence of his boyhood interest in chemistry is fascinating. His obvious love of our science is inspiring. And he has expressed both in words that are brilliantly chosen and a joy to read. In a profile of Sacks that appeared in Chemical and Engineering News (January 10, 2000), Madeleine Jacobs relates that he is writing a book on his boyhood encounters with chemistry (to be published by Alfred A. Knopf). I am looking forward to that with great anticipation. During 1999 he also wrote an article on the periodic table in the New York Times Magazine (April 18) and an op-ed piece on chemistry sets in the New York Times (May 13). In the latter he describes how hard it is these days for a nonchemist, especially a young one, to obtain chemicals to experiment with. Chemistry sets are not what they used to be! Sacks's writings contain important messages for all of us who teach chemistry and all who are involved in piquing students' interest in our subject. A brief excerpt from his New Yorker article illustrates my point. I knew zinc--the dull, slightly bluish birdbath in the garden was made of zinc--and tin, from the heavy tinfoil in which sandwiches were wrapped for a picnic. My mother showed me that when tin or zinc was bent it uttered a special "cry." "It's due to deformation of the crystal structure," she said, forgetting that I was five and could not understand her--and yet her words made me

  6. Young students experience theory

    2004-01-01

    Three sixteen-year-old students from the International School of Geneva, La Chataigneraie have spent a week finding out about the life of a theoretical physicist at CERN. Student Peter Bishop at the blackboard with Robert Fleischer of Theory Division. Peter Bishop, Sam Schoenholz and Alexander Hultin spent the time with the Theory Unit of the Physics department. The visit was at the suggestion of the students themselves, who are required to undertake work experience at an organization, gaining insights into professional life, as part of their studies. After an introduction to CERN at Microcosm, each student had the opportunity to learn about physics at a level well beyond their current academic training. They were mentored by theoretical physicists who introduced them to the basics of particle physics, discussing physics in general as well as topics such as predicting the mass of the Higgs boson and cosmology. A visit to CMS, guided by Ariane Frey, proved very impressive, but the working conditions of physi...

  7. My experience in arbitration

    Claude Witz

    2011-12-01

    Full Text Available This paper deals with the nature of arbitration as one of the alternatives in dispute resolution processes different from mediation and conciliation, and obviously, from judicial adjudication. Unlike a mediator or a conciliator, an arbitrator is empowered to pass a judgement, like a court. In other words, the arbitrator will render a decision which is binding for the parties. The arbitrator has the jurisdictio, like a judge. Although the office of a judge and an arbitrator is the same, the source of their power is different. The judge’s power originates from a State, whereas the power of the arbitrator results primarily from a contract. Unlike the court, the arbitrator lacks the imperium, i.e. the power to make the award enforceable. When a party refuses to enforce the award, enforceability can only be provided by the judge or an authority of the state where the award has to be enforced. In a certain sense the state thus provides the back up for the arbitration system. This paper presents personal thoughts drawn from the author’s professional experience as an arbitrator in Franco-German disputes.

  8. Project Feedback Experience

    In the financial responsibility of the Karlsruhe Research Center 5 reactors and 1 reprocessing plant are being decommissioned with these activities reaching a total volume of 2 billion Euros. Three reactor projects have already been completed: The FR 2 research reactor is in the state of safe enclosure i.e., only the reactor pressure vessel and its internals are in place. Apart from that the reactor building is empty. The reactors KKN and HDR have been dismantled completely and the sites have been re-cultivated (green field) again. The state of the other projects are as follows: - Multi Purpose Research Reactor (MZFR): remote controlled dismantling of the reactor vessel and internals; - Compact Sodium Cooled Reactor (KNK): installation of the equipment for the remote controlled dismantling of the reactor tank and its internals; - Karlsruhe Reprocessing Plant (WAK): decontamination of the process cells, construction of a vitrification facility for the treatment of the high-active waste concentrate (HAWC) and commission of the equipment for the segmentation of the HAWC storage tanks. The experience gained so far with regard to the technology applied and the licensing procedure will be described and discussed in the paper. The decommissioning progress is decisively determined by the direct treatment and disposal of the generated radioactive wastes. The FZK facilities and processing units available for this purpose will be also presented. Furthermore, the consequences of establishing specific organizational units as well as of a consistent project management will be outlined. (author)

    2013-07-01

    LOPES is a digital interferometric antenna array co-located with the particle detector KASCADE-Grande at the Karlsruhe Institute of Technology (KIT).Being one of the pioneers in the detection and in the interferometric analysis of the radio emission from cosmic ray air showers at MHz frequencies, LOPES still provides us with relevant results. Since the first measurements in 2003, LOPES was reconfigured several times in order to test different setup and antenna types, and to address different questions concerning the radio emission from air showers. In its latest configuration, a tripole antenna is tested, which makes LOPES able to measure all three components of the electric field vector of the radio emission, and to better compare measurements with simulations. This talk will give an overview of the recent status and outcomes of the LOPES experiment. Thanks to a large statistics of well reconstructed events, LOPES measurements are used for comparison with simulations (REAS and CoREAS), giving a crucial contribution in better understanding the radio emission mechanisms. The updated results concerning a successful reconstruction of fundamental air shower parameters, such as the arrival direction, the primary energy and the depth of the shower maximum, with reasonably high precision are presented.

  11. Glovebox fire experiment, (1)

    The gloveboxes used for plutonium facilities in Japan and foreign countries have considerable combustibles as their components, so that the fire resistivity of the gloveboxes is a serious problem in the safety evaluation of the facilities. Actually, a big fire having burned gloveboxes occurred in a foreign weapon facility. But the fire in the weapon facility should be distinguished from that in nuclear fuel facilities, since the former handles quite combustible plutonium metal, while the latter handle quite stable plutonium oxide. The countermeasures to fires should be decided, considering the properties and quantity of combustibles around gloveboxes and ventilation systems, as the probability and scale of fires can be presumed from them. From the viewpoint of safety, the experiment on glovebox fires was carried out by the Plutonium Fuel Division, PNC. The experimental conditions are explained. The samples were the acrylic resin panels with four glove ports and a small glovebox currently used. The glovebox showed the considerable fire resistance, and the panel hardly burned. The weakest component of the glovebox against fire was the gloves. The countermeasure to curtain the gloves with an insulating material seemed to be effective. The ventilation of the room and the glovebox worked as fire preventer at least in the first stage of fire. (Kako, I.)

  12. The 'Patient experience' revolution.

    2014-02-01

    We're arguably at the most pivotal time in our young profession. The ACA has provided EMS an unprecedented opportunity to become a part of the healthcare system, a move that many of us have dreamed about for decades. We need to pay attention to the changing dynamics of the environment in which we operate. The factors that currently impact hospitals, doctors and other healthcare providers will also impact us sooner than we think. Take the time to help shape our future and how we participate in this new healthcare system. It's time to focus on the patient and the patient's experience with our service. Wayne Gretzky said two important things during an interview when he was asked what makes him such a great hockey player. One was, "You miss 100% of the shots you don't take." The other was, "A good hockey player plays where the puck is. A great hockey player plays where the puck is going to be. I skate to where the puck is going to be, not where it has been." Our advice to you is to go ahead, take the shot, get ahead of the other team and focus on improved customer satisfaction sooner rather than later. PMID:24660359

  13. The Brazilian Experience

    Agostini, Antonio Carlos S. de

    1998-12-31

    This presentation discusses the technology and experience of Petrobras in the development of deep-water exploitation off the coast of Brazil. The company recently found important oil deposits in waters over 300 m deep in Campos Basin, the main petroleum province in Brazil, located offshore Rio de Janeiro State. It is estimated that 50% of the new discoveries will take place in waters deeper than 1000 m. Unlike other companies, Petrobras made an option to develop its offshore fields by means of sub-sea equipment and floating production units. This was possible mainly because of the characteristics of the reservoirs and the mild environmental conditions in Campos Basin. Petrobras has 288 subsea trees on the seabed, 48 subsea manifolds and 21 floating production units in operation. The company has constantly moved on to deeper and deeper waters and by the end of 1998 a new milestone will be achieved with a Roncador field subsea well at 1853 m. Procap-2000, a strategic research and development corporate programme for ultra-deep water technology, was developed. Other innovations by Petrobras are also discussed. 3 figs.

  17. An emergency exercise experience

    Emergency exercises are held to satisfy regulatory requirements and to hopefully improve emergency response. Unfortunately, simply satisfying the requirement is often the principle concern of those who plan drills. Argonne National Laboratory has detailed emergency plans, and each Division is required to have an emergency exercise at least once each year. However, the pressure to minimize time taken from research efforts reduces the value of many exercises. During the past year, the Health Physics Section at ANL made an effort to optimize the information and training obtained in the time allotted for a drill. The purpose of this presentation is to share our approach and the results of one experience with the anticipation that it will stimulate others to critically look at emergency exercises in their organizations. To be of value, an emergency response exercise must have clear objectives, allow organized reporting, contain a documented follow-up critique, and provide for correction of deficiencies in training and in the emergency plan. A mock criticality incident at ANL was used to test specific emergency response capabilities. The objectives of the 45 minute exercise included testing: (1) how well Health Physics, Fire Department, and Medical personnel would deal with the unexpected find of an unconscientious, contaminated person in a high radiation field; (2) the capability to quickly predict environmental radioactivity concentration for a surprise mock stack release of fission products; (3) the time required and accuracy for dose assessment from personnel dosimeters, criticality dosimeters and samples of blood and hair which were irradiated to known doses in the Argonne Janus reactor; (4) how well Health Physics personnel would identify and sort 'exposed persons' who had no dosimeters (small radioactive sources were hidden on select persons); and (5) how persons from the evacuated building would be accounted for. As a result of findings, special Health Physics

  18. Regulatory and operating experience

    Regulatory and operating experience in the disposal of radioactive waste can be divided into three time periods, World War II and its aftermath, Post World War II till the end of the cold war, and crystal ball gazing into the future. In the first period, there was little regulatory guidance and operating practices, all conducted under wartime secrecy conditions, sometimes were not even up to the norms of the times. Environmental releases resulted in some seriously contaminated sites and high dosages to some offsite populations. Failure to consider even the storage of wastes in a systems context resulted in some stocks that were difficult to recover, treat and dispose of in a final manner. In the second period, increasing civilian uses of nuclear power and isotopes for medical, research, and industrial purposes and military pressure for increased production of Pu-239 resulted in large and more dispersed disposal of radioactive wastes. Regulatory regimes, following growing environmental consciousness, came into existence that minimized exposure to environmental contamination. Practices, in most instances, increasingly conformed to these regulatory demands. The future is unknowable. However, for high level wastes, except for thermodynamically stable forms, no technology can guarantee safety and present methodologies are calculated to produce doses orders of magnitude lower than regulatory limits. Therefore, it is possible that research will be limited to no higher technology than is reasonably achievable. Whereas for low level waste, where proof is practicably possible, as high technology as is reasonably achievable will be best in the long run. (author). 24 refs, 5 figs, 3 tabs

    SELENE (KAGUYA) PDAP experiment Shin-ichi Sobue, Yukio Yamamoto, Hayato Okumura, Tatsuaki Okada and Iku Shinohara SELENE (whose Japanese Nickname is 'KAGUYA' from Japanese old story) is the most sophisticated lunar exploration mission in the post-Apollo Era. SELENE consists of the main orbiter and two small satellites - the Relay satellite 'OKINA' and the VRAD satellite 'OUNA'. The main orbiter will observe the distribution of the elements and minerals on the surface, the surface and sub-surface structure, the gravity field, the remnant of the magnetic field and the environment of energetic particles and plasma of the Moon. The Relay satellite 'OKINA' will relay the Doppler ranging signal between the Main Orbiter and the ground station for the world's first direct measurement of he gravity field in the farside of the Moon. The differential VLBI Radio-Sources on board the Relay satellite "OKINA" and the VRAD satellite 'OUNA' are used to determine the gravity field of the Moon most precisely. SELENE data will be used for studying 'lunar origin and evolution' and "exploration" of the Moon and will be archived and distributed in PDS-like format with the descriptions of data format and technical information. This PDS-like format is slightly different from catalog for search and order in catalog DB (some keyword (attribute) and value definition are different). Thus, to establish the catalog interoperability function with PDS/NASA and PSA/ESA by using PDAP, it is necessary to develop PDS label (keyword and value) mapping software to translate SELENE PDS like label extracted from SELENE product to PDS compatible PDS-label and archive such the label information to our prototype catalog database We also implemented the retrieving prototype system to access that prototype catalog database. Those systems were finished to implement by the end of this March. This paper describes the result of this prototype development and evaluation report. In addition, this paper shows some

  20. Fast reactor operating experience

    At the beginning of electricity generation from nuclear power there was the breeder, which fulfilled its duty in a number of smaller test and experimental reactors within national programs. Over the years, some of those reactors have attained impressive availabilities, while others have helped to improve our knowledge by the negative results they contributed. Worldwide a decisive step was taken by the mid- to late sixties in the planning and construction of medium sized demonstration fast breeder power plants (250 to 350 MW). In the Federal Republik of Germany, this step is taken belatedly in building the SNR-300. BN-350 in the USSR, Phenix in France, and PFR in the United Kingdom have now been in operation for some ten years. Over that period, valuable experience has been accumulated in sodium technology. The operating behavior of all components and systems working in sodium is called excellent; the hazards associated with sodium, the fire hazard in particular, thus often seem to be greatly overrated. Leakages have been brought under control. It has always been possible so far to trace them back to systemic faults produced in the welding process. The ability of fast sodium cooled reactors to produce more nuclear fuel than they consume has been demonstrated in Phenix, whose breeding ration has been measured to be 1.16. The first true large breeder, Super Phenix in France, is to be commissioned already in 1985. In building another three breeder power plants the European partners in an association hope to achieve the commercial breakthrough of the breeder line. (orig.)

  1. The isotope correlation experiment

    The ESARDA working group on Isotopic Correlation Techniques, ICT and Reprocessing Input Analysis performed an Isotope Correlation Experiment, ICE with the aim to check the feasibility of the new technique. Ten input batches of the reprocessing of the KWO fuel at the WAK plant were analysed by 4 laboratories. All information to compare ICT with the gravimetric and volumetric methods was available. ICT combined with simplified reactor physics calculation was included. The main objectives of the statistical data evaluation were detection of outliers, the estimation of random errors and of systematic errors of the measurements performed by the 4 laboratories. Different methods for outlier detection, analysis of variances, Grubbs' analysis for the constant-bias model and Jaech's non-constant-bias model were applied. Some of the results of the statistical analysis may seem inconsistent which is due to the following reasons. For the statistical evaluations isotope abundance data (weight percent) as well as nuclear concentration data (atoms/initial metal atoms) were subjected to different outlier criteria before being used for further statistical evaluations. None of the four data evaluation groups performed a complete statistical data analysis which would render possible a comparison of the different methods applied since no commonly agreed statistical evaluation procedure existed. The results prove that ICT is as accurate as conventional techniques which have to rely on costly mass spectrometric isotope dilution analysis. The potential of outlier detection by ICT on the basis of the results from a single laboratory is as good as outlier detection by costly interlaboratory comparison. The application of fission product or Cm-244 correlations would be more timely than remeasurements at safeguards laboratories

  2. GNF2 Operating Experience

    GNF's latest generation fuel product, GNF2, is designed to deliver improved nuclear efficiency, higher bundle and cycle energy capability, and more operational flexibility. But along with high performance, our customers face a growing need for absolute fuel reliability. This is driven by a general sense in the industry that LWR fuel reliability has plateaued. Too many plants are operating with fuel leakers, and the impact on plant operations and operator focus is unacceptable. The industry has responded by implementing an INPO-coordinated program aimed at achieving leaker-free reliability by 2010. One focus area of the program is the relationship between fuel performance (i.e., duty) and reliability. The industry recognizes that the right balance between performance and problem-free fuel reliability is critical. In the development of GNF2, GNF understood the requirement for a balanced solution and utilized a product development and introduction strategy that specifically addressed reliability: evolutionary design features supported by an extensive experience base; thoroughly tested components; and defense-in-depth mitigation of all identified failure mechanisms. The final proof test that the balance has been achieved is the application of the design, initially through lead use assemblies (LUAs), in a variety of plants that reflect the diversity of the BWR fleet. Regular detailed surveillance of these bundles provides the verification that the proper balance between performance and reliability has been achieved. GNF currently has GNF2 lead use assemblies operating in five plants. Included are plants that have implemented extended power up-rates, plants on one and two-year operating cycles, and plants with and without NobleChemTM and zinc injection. The leading plant has undergone three pool-side inspections outages to date. This paper reviews the actions taken to insure GNF2's reliability, and the lead use assembly surveillance data accumulated to date to validate

  4. Transverse Injection Experiment

    The motion of a plasma stream injected transverse to a magnetic field has been discussed by several authors. In early experiments with the injection of a fast (50 to 70 cm/μsec) dense (1014 ion/cm3) plasma transverse to a magnetic field, a self polarization electric field was observed and the stream crossed the magnetic field with an E x B drift. The magnetic field was only slightly disturbed by the stream (| ΔB/B | <0.1) while the drift across magnetic fields up to 5 kG was at approximately the velocity of the injected stream. The height of the stream in the direction of V x B is compressed as it drifts into high magnetic field regions. At the same time, electron density measurements using interferometry techniques with the He-Ne laser show that the transverse field up to 7 kG causes no appreciable spreading of the stream to take place in the direction of B. Of interest is the action of the stream as it crosses a region where magnetic field lines reverse direction about a field null line. As the stream proceeds across the separatrix between the two field line directions, the electric field must change direction if the stream drift is to continue. The stream halts in the region of the separatrix while large currents are measured along magnetic field lines connecting the front of the stream with the following portions. Insulators placed to interrupt the current allow the stream to proceed into the reversed field region. By making use of the inductance associated with the depolarization current when magnetic field lines are tied at some distance to the side of the stream, a separation of fast and slow stream components can be made. The cutoff of the slow stream component is observed with the He-Ne laser interferometry techniques. Electric field measurements at several points along the stream show some of the more complicated features of the plasma flow. (author)

  5. Global Troposphere Experiment Project

    Bandy, Alan R.; Thornton, Donald C.

    1997-01-01

    For the Global Troposphere Experiment project Pacific Exploratory Measurements West B (PEM West B), we made determinations of sulfur dioxide (SO2) and dimethyl sulfide (DMS) using gas chromatography-mass spectrometry with isotopically labelled internal standards. This technique provides measurements with precision of 1 part-per-trillion by volume below 20 pptv and 1% above 20 pptv. Measurement of DMS and SO2 were performed with a time cycle of 5-6 minutes with intermittent zero checks. The detection limits were about 1 pptv for SO2 and 2 pptv for DMS. Over 700 measurements of each compound were made in flight. Volcanic impacts on the upper troposphere were again found as a result of deep convection in the tropics. Extensive emission of SO2 from the Pacific Rim land masses were primarily observed in the lower well-mixed part of the boundary layer but also in the upper part of the boundary layer. Analyses of the SO2 data with aerosol sulfate, beryllium-7, and lead-210 indicated that SO2, contributed to half or more of the observed total oxidized sulfur (SO2 plus aerosol sulfate) in free tropospheric air. Cloud processing and rain appeared to be responsible for lower SO2 levels between 3 and 8.5 km than above or below this region. During both phases of PEM-West, dimethyl sulfide did not appear to be a major source of sulfur dioxide in the upper free troposphere over the western Pacific Ocean. In 1991 the sources Of SO2 at high altitude appeared to be both anthropogenic and volcanic with an estimated 1% being solely from DMS. The primary difference for the increase in the DMS source was the very low concentration of SO2 at high altitude. In the midlatitude region near the Asian land masses, DMS in the mixed layer was lower than in the tropical region of the western Pacific. Convective cloud systems near volcanoes in the tropical convergence in the western Pacific troposphere were a major source of SO2 at high altitudes during PEM-West B. High levels of SO2 were

    Like experiments performed at a laboratory bench, the data associated with an e-Science experiment are of reduced value if other scientists are not able to identify the origin, or provenance, of those data. Provenance information is essential if experiments are to be validated and verified by others, or even by those who originally performed them.

  7. Simulator experiments: effects of NPP operator experience on performance

    Beare, A.N.; Gray, L.H.

    1984-01-01

    During the FY83 research, a simulator experiment was conducted at the control room simulator for a GE Boiling Water Reactor (BWR) NPP. The research subjects were licensed operators undergoing requalification training and shift technical advisors (STAs). This experiment was designed to investigate the effects of senior reactor operator (SRO) experience, operating crew augmentation with an STA and practice, as a crew, upon crew and individual operator performance, in response to anticipated plant transients. Sixteen two-man crews of licensed operators were employed in a 2 x 2 factorial design. The SROs leading the crews were split into high and low experience groups on the basis of their years of experience as an SRO. One half of the high- and low-SRO experience groups were assisted by an STA. The crews responded to four simulated plant casualties. A five-variable set of content-referenced performance measures was derived from task analyses of the procedurally correct responses to the four casualties. System parameters and control manipulations were recorded by the computer controlling the simulator. Data on communications and procedure use were obtained from analysis of videotapes of the exercises. Questionnaires were used to collect subject biographical information and data on subjective workload during each simulated casualty. For four of the five performance measures, no significant differences were found between groups led by high (25 to 114 months) and low (1 to 17 months as an SRO) experience SROs. However, crews led by low experience SROs tended to have significantly shorter task performance times than crews led by high experience SROs. The presence of the STA had no significant effect on overall team performance in responding to the four simulated casualties. The FY84 experiments are a partial replication and extension of the FY83 experiment, but with PWR operators and simulator.

  9. Remembered Experiences and Revisit Intentions

    Barnes, Stuart; Mattsson, Jan; Sørensen, Flemming

    2016-01-01

    Tourism is an experience-intensive sector in which customers seek and pay for experiences above everything else. Remembering past tourism experiences is also crucial for an understanding of the present, including the predicted behaviours of visitors to tourist destinations. We adopt a longitudinal...... approach to memory data collection from psychological science, which has the potential to contribute to our understanding of tourist behaviour. In this study, we examine the impact of remembered tourist experiences in a safari park. In particular, using matched survey data collected longitudinally and PLS...... path modelling, we examine the impact of positive affect tourist experiences on the development of revisit intentions. We find that longer-term remembered experiences have the strongest impact on revisit intentions, more so than predicted or immediate memory after an event. We also find that remembered...

  10. Data analysis for electronic experiments

    In this lecture I schell attempt to cover the principal off-line software aspects in electronic experiments. Of course, this is too ambitious an undertaking for two reasons: Firstly the field is vast, and some important aspect will certainly have escaped my attention. Secondly, the choice of methods, features, algorithms, and packages presented will be biased through my personal opinion and experience, although to some extent it is influenced as well by the opinion and experience of my colleagues, who, like myself, are working in this field at CERN. Therefore, beware. Whenever I shall claim something to be evident, a matter of experience -- a fact --it ain't necessarily so. On the other hand, it will not be entirely wrong, since our experience is based on something like 30 experiments in high-energy physics using electronic for other people, and although these people are of course misled, one has to admit their existence.

  11. Dashboard for the LHC experiments

    In this paper we present the Experiment Dashboard monitoring system, which is currently in use by four Large Hadron Collider (LHC) experiments. The goal of the Experiment Dashboard is to monitor the activities of the LHC experiments on the distributed infrastructure, providing monitoring data from the virtual organization (VO) and user perspectives. The LHC experiments are using various Grid infrastructures (LCG/EGEE, OSG, NDGF) with correspondingly various middleware flavors and job submission methods. Providing a uniform and complete view of various activities like job processing, data movement and publishing, access to distributed databases regardless of the underlying Grid flavor is the challenging task. In this paper we will describe the Experiment Dashboard concept, its framework and main monitoring applications

  12. OSMOSE experiment representativity studies

    leads to a uniform well-behaved system so that the reactor configuration is in the fundamental mode. In fact, an important property of the oscillation experiments performed in the OSMOSE program is that the neutron flux at the sample location has reached the asymptotic fundamental mode of the MINERVE lattice. This property allows the use of simple spatial methods for the analysis (e.g. a lattice code with axial buckling representing the leakage), without loss of accuracy. The computational challenge is then reduced to the need of an appropriate cross-section processing and of accurate resonance shielding algorithms. In the present study, calculations have been performed to investigate the similarity of the flux spectra at the sample position of different OSMOSE configurations with the neutron energy distributions characterizing existing thermal and fast reactors proposed under the advanced reactor programs Gen-IV, GNEP and NGNP

    An experimental approach to studying the properties of word embeddings is proposed. Controlled experiments, achieved through modifications of the training corpus, permit the demonstration of direct relations between word properties and word vector direction and length. The approach is demonstrated using the word2vec CBOW model with experiments that independently vary word frequency and word co-occurrence noise. The experiments reveal that word vector length depends more or less linearly on bo...

    Richtmyer-Meshkov experiments are conducted on the Nova laser with strong radiatively driven shocks (Mach > 20) in planar, two-fluid targets with Atwood number A < 0. Single mode interfacial perturbations are used to test linear theory and 3D random perturbations are used to study turbulent mix. Rayleigh-Taylor experiments are conducted on a new facility called the Linear Electric Motor (LEM) in which macroscopic fluids are accelerated electromagnetically with arbitrary acceleration profiles. The initial experiments are described. Hydrodynamic simulations in 2D are in reasonable agreement with the experiments, but these studies show that simulations in 3D with good radiation transport and equation of state are needed.

  5. Experiment prediction for Loft Nonnuclear Experiment L1-4

    A computer analysis, using the WHAM and RELAP4 computer codes, was performed to predict the LOFT system thermal-hydraulic response for Experiment L1-4 of the nonnuclear (isothermal) test series. Experiment L1-4 will simulate a 200 percent double-ended offset shear in the cold leg of a four-loop large pressurized water reactor. A core simulator will be used to provide a reactor vessel pressure drop representative of the LOFT nuclear core. Experiment L1-4 will be initiated with a nominal isothermal primary coolant temperature of 282.20C, a pressurizer pressure of 15.51 MPa, and a primary coolant flow of 270.9 kg/s. In general, the predictions of saturated blowdown for Experiment Ll-4 are consistent with the expected system behavior, and predicted trends agree with results from Semiscale Test S-01-4A, which simulated the Ll-4 experiment conditions

  6. DHS Research Experience Summary

    Venkatachalam, V

    2008-10-24

    I learned a great deal during my summer internship at Lawrence Livermore National Laboratory (LLNL). I plan to continue a career in research, and I feel that my experience at LLNL has been formative. I was exposed to a new area of research, as part of the Single Particle Aerosol Mass Spectrometry (SPAMS) group, and I had the opportunity to work on projects that I would not have been able to work on anywhere else. The projects both involved the use of a novel mass spectrometer that was developed at LLNL, so I would not have been able to do this research at any other facility. The first project that Zachary and I worked on involved using SPAMS to detect pesticides. The ability to rapidly detect pesticides in a variety of matrices is applicable to many fields including public health, homeland security, and environmental protection. Real-time, or near real-time, detection of potentially harmful or toxic chemical agents can offer significant advantages in the protection of public health from accidental or intentional releases of harmful pesticides, and can help to monitor the environmental effects of controlled releases of pesticides for pest control purposes. The use of organophosphate neurotoxins by terrorists is a possibility that has been described; this is a legitimate threat, considering the ease of access, toxicity, and relatively low cost of these substances. Single Particle Aerosol Mass Spectrometry (SPAMS) has successfully been used to identify a wide array of chemical compounds, including drugs, high explosives, biological materials, and chemical warfare agent simulants. Much of this groundbreaking work was carried out by our group at LLNL. In our work, we had the chance to show that SPAMS fulfills a demonstrated need for a method of carrying out real-time pesticide detection with minimal sample preparation. We did this by using a single particle aerosol mass spectrometer to obtain spectra of five different pesticides. Pesticide samples were chosen to

  7. Welcome to the experience economy.

    Pine, B J; Gilmore, J H

    1998-01-01

    First there was agriculture, then manufactured goods, and eventually services. Each change represented a step up in economic value--a way for producers to distinguish their products from increasingly undifferentiated competitive offerings. Now, as services are in their turn becoming commoditized, companies are looking for the next higher value in an economic offering. Leading-edge companies are finding that it lies in staging experiences. To reach this higher level of competition, companies will have to learn how to design, sell, and deliver experiences that customers will readily pay for. An experience occurs when a company uses services as the stage--and goods as props--for engaging individuals in a way that creates a memorable event. And while experiences have always been at the heart of the entertainment business, any company stages an experience when it engages customers in a personal, memorable way. The lessons of pioneering experience providers, including the Walt Disney Company, can help companies learn how to compete in the experience economy. The authors offer five design principles that drive the creation of memorable experiences. First, create a consistent theme, one that resonates throughout the entire experience. Second, layer the theme with positive cues--for example, easy-to-follow signs. Third, eliminate negative cues, those visual or aural messages that distract or contradict the theme. Fourth, offer memorabilia that commemorate the experience for the user. Finally, engage all five senses--through sights, sounds, and so on--to heighten the experience and thus make it more memorable.

  14. Stretching the Traditional Notion of Experiment in Computing: Explorative Experiments.

    Schiaffonati, Viola

    2016-06-01

    Experimentation represents today a 'hot' topic in computing. If experiments made with the support of computers, such as computer simulations, have received increasing attention from philosophers of science and technology, questions such as "what does it mean to do experiments in computer science and engineering and what are their benefits?" emerged only recently as central in the debate over the disciplinary status of the discipline. In this work we aim at showing, also by means of paradigmatic examples, how the traditional notion of controlled experiment should be revised to take into account a part of the experimental practice in computing along the lines of experimentation as exploration. Taking inspiration from the discussion on exploratory experimentation in the philosophy of science-experimentation that is not theory-driven-we advance the idea of explorative experiments that, although not new, can contribute to enlarge the debate about the nature and role of experimental methods in computing. In order to further refine this concept we recast explorative experiments as socio-technical experiments, that test new technologies in their socio-technical contexts. We suggest that, when experiments are explorative, control should be intended in a posteriori form, in opposition to the a priori form that usually takes place in traditional experimental contexts.

  15. Simulator experiments: effects of NPP operator experience on performance

    Experiments are being conducted on nuclear power plant (NPP) control room training simulators by the Oak Ridge National Laboratory, its subcontractor, General Physics Corporation, and participating utilities. The experiments are sponsored by the Nuclear Regulatory Commission's (NRC) Human Factors and Safeguards Branch, Division of Risk Analysis and Operations, and are a continuation of prior research using simulators, supported by field data collection, to provide a technical basis for NRC human factors regulatory issues concerned with the operational safety of nuclear power plants. During the FY83 research, a simulator experiment was conducted at the control room simulator for a GE boiling water reactor (BWR) NPP. The research subjects were licensed operators undergoing requalification training and shift technical advisors (STAs). This experiment was designed to investigate the effects of (a) senior reactor operator (SRO) experience, (b) operating crew augmentation with an STA and (c) practice, as a crew, upon crew and individual operator performance, in response to anticipated plant transients. The FY84 experiments are a partial replication and extension of the FY83 experiment, but with PWR operators and simulator. Methodology and results to date are reported

  16. Status of neutrino mass experiments

    Fackler, O.

    1985-12-01

    In 1980 two experiments ignited a fertile field of research the determination of the neutrino masses. Subsequently, over 35 experiments using a variety of techniques have probed or are probing this question. Primarily I will discuss electron antineutrino (hereafter referred to as neutrino) mass experiments. However, let me begin in Section I to discuss astronomical and terrestrial observations which motivated these experiments. In Section II, I will quote limits from muon and tau mass determinations. These limits are more thoroughly discussed in other papers. I will continue by describing the four approaches used to measure the electron neutrino mass. In Section III, tritium beta decay mass determinations will be reviewed. This section includes a general summary of previous experimental results, and discussion of the major ongoing experiments. Section IV offers concluding remarks. 24 refs., 24 figs.

  18. REXIB: Remote Experiments Interface Builder

    Jose M. Ferreira

    2006-08-01

    Full Text Available Remote Experimentation is an educational resource that allows teachers to strengthen the practical contents of science & engineering courses. However, building up the interfaces to remote experiments is not a trivial task. Although teachers normally master the practical contents addressed by a particular remote experiment they usually lack the programming skills required to quickly build up the corresponding web interface. This paper describes the automatic generation of experiment interfaces through a web-accessible Java application. The application displays a list of existent modules and once the requested modules have been selected, it generates the code that enables the browser to display the experiment interface. The tools’ main advantage is enabling non-tech teachers to create their own remote experiments.

    The T2K experiment is a long baseline neutrino oscillation experiment. Its main goal is to measure the last unknown lepton sector mixing angle θ13 by observing νe appearance in a νμ beam. It also aims to make a precision measurement of the known oscillation parameters, Δm232 and sin22θ23, via νμ disappearance studies. Other goals of the experiment include various neutrino cross-section measurements and sterile neutrino searches. The experiment uses an intense proton beam generated by the J-PARC accelerator in Tokai, Japan, and is composed of a neutrino beamline, a near detector complex (ND280), and a far detector (Super-Kamiokande) located 295 km away from J-PARC. This paper provides a comprehensive review of the instrumentation aspect of the T2K experiment and a summary of the vital information for each subsystem.

  3. Experiments at CERN in 1985

    This book is a compilation of the current experimental program at CERN. The experiments listed are being performed at one of the following machines: the Super Proton Synchrotron (SPS), the Proton Synchrotron (PS) and the Synchro-Cyclotron (SC). The four experiments to be done by means of the Large Electron Positron machine (LEP) are also listed. The schematic layouts of beams and experiments at the various machines are given in the beginning of the report. The experiment goals and methods are briefly described and a schematic layout of the apparatus is included. Lists of participants and their institutions are also given. The status of the experiments (preparation, data-taking, completed) corresponds to the situation as of 1st November, 1985. ''Completed'' means only that data-taking is finished, not necessarily the analysis of the results; this status is kept for two years and then the experiment is removed from the catalogue. A complete list of all experiments published in this book since 1975 is given at the end of the catalogue. (orig./HSI)

  4. An ontology of scientific experiments.

    Soldatova, Larisa N; King, Ross D

    2006-12-22

    The formal description of experiments for efficient analysis, annotation and sharing of results is a fundamental part of the practice of science. Ontologies are required to achieve this objective. A few subject-specific ontologies of experiments currently exist. However, despite the unity of scientific experimentation, no general ontology of experiments exists. We propose the ontology EXPO to meet this need. EXPO links the SUMO (the Suggested Upper Merged Ontology) with subject-specific ontologies of experiments by formalizing the generic concepts of experimental design, methodology and results representation. EXPO is expressed in the W3C standard ontology language OWL-DL. We demonstrate the utility of EXPO and its ability to describe different experimental domains, by applying it to two experiments: one in high-energy physics and the other in phylogenetics. The use of EXPO made the goals and structure of these experiments more explicit, revealed ambiguities, and highlighted an unexpected similarity. We conclude that, EXPO is of general value in describing experiments and a step towards the formalization of science. PMID:17015305

    Experiments with an electric motor provide good opportunity to demonstrate some basic laws of electricity and magnetism. The aim of the experiments with a low-power dc motor is to show how the motor approaches its steady rotation and how its torque, mechanical power and efficiency depend on the rotation velocity. The tight relationship between the mechanical and electrical parameters of the motor is clearly seen. The measurements are carried out with the ScienceWorkshop data-acquisition system and the DataStudio software from PASCO scientific. The experiments are well related to university courses of electricity and magnetism and can be used in undergraduate laboratories or for lecture demonstrations.

We describe the processes, data, and knowledge involved in the construction of whole ventricular multiscale models of cardiac...... electrophysiology. Our analysis reveals that models, simulations, and experiments are intertwined, in an assemblage that is a system itself, namely the model-simulation-experiment (MSE) system. We argue that validation is part of the whole MSE system and is contingent upon 1) understanding and coping with sources...

    The BRAHMS experiment at RHIC was conceived to pursue the understanding of nuclear matter under extreme conditions by detailed measurements of charged hadrons over the widest possible range of rapidity and transverse momentum. The experiment consists of two spectrometers with complementary charged hadron detection capabilities as well as a series of global detectors for event characterization. A series of tracking detectors, time-of-flight arms and Cherenkov detectors enables momentum determination and particle identification over a wide range of rapidity and transverse momentum. Technical details and performance results are presented for the various detector subsystems. The performance of the entire system working together is shown to meet the goals of the experiment.

  18. ENEA experience in LBE technology

    Since 1999, several facilities have been operated with flowing LBE in the frame of ADS R and D activities at CR ENEA Brasimone. The experimental activities have gone through thermal-hydraulics, heat exchange, science of materials, qualification of components and operational procedures. Thanks to the performed work, a large amount of observations were made, and experience was gained. This paper is focused on the survey of these experiences gained, in order to point out advantages and disadvantages of the LBE technologies. In particular, experience on plant components, measurement instrumentations and operational procedures will be pointed out

  19. Mystical experience in the lab

    Andersen, Marc Nicklas; Schjødt, Uffe; Nielbo, Kristoffer Laigaard;

    2014-01-01

    We review previous attempts to study mystical experience and point to problems inherent to certain methodologies. Focusing on studies that use controlled environments we advocate taking an experimental approach to mysticism. To demonstrate the viability of this approach, we report findings from a......, our data indicate that the experiences reported by the participants had a high degree of authenticity and had lasting effects in terms of memory and attribution. These findings demonstrate that at least some forms of mystical experience can be studied in a controlled environment. Prospects and...

  1. A quantum delayed choice experiment

    Peruzzo A.; Shadbolt P.; Brunner N.; Popescu S.; O'Brien J.L.

    2012-01-01

    Quantum systems exhibit particle-like or wave-like behaviour depending on the experimental apparatus they are confronted by. This wave-particle duality is at the heart of quantum mechanics, and is fully captured in Wheeler's famous delayed choice gedanken experiment. In this variant of the double slit experiment, the observer chooses to test either the particle or wave nature of a photon after it has passed through the slits. Here we report on a quantum delayed choice experiment, based on a q...

  2. Synchronous Sampling for Distributed Experiments

    Wittkamp, M.; Ettl, J.

    2015-09-01

    Sounding Rocket payloads, especially for atmospheric research, often consists of several independent sensors or experiments with different objectives. The data of these sensors can be combined in the post processing to improve the scientific results of the flight. One major requirement for this data-correlation is a common timeline for the measurements of the distributed experiments. Within this paper we present two ways to achieve absolute timing for asynchronously working experiments. The synchronization process is using the Global Positioning System (GPS) and a standard serial communication protocol for transport of timestamps and flight-states.

  6. Introduction to Statistically Designed Experiments

    Heaney, Mike

    2016-09-13

    Statistically designed experiments can save researchers time and money by reducing the number of necessary experimental trials, while resulting in more conclusive experimental results. Surprisingly, many researchers are still not aware of this efficient and effective experimental methodology. As reported in a 2013 article from Chemical & Engineering News, there has been a resurgence of this methodology in recent years (http://cen.acs.org/articles/91/i13/Design-Experiments-Makes-Comeback.html?h=2027056365). This presentation will provide a brief introduction to statistically designed experiments. The main advantages will be reviewed along with the some basic concepts such as factorial and fractional factorial designs. The recommended sequential approach to experiments will be introduced and finally a case study will be presented to demonstrate this methodology.

    2006-01-01

    level. However, interaction design and HCI yet has little to offer designers working with physico-spatial and experiential issues in practical design cases. In this paper, I argue that experiments that explore spatial and experiential aspects are crucial in developing the practice of interaction design....... These  aspects may be brought to the forefront by engaging in, reflecting upon, and reporting from physico-spatial design experiments, and by making spatial and experience-oriented design representations part of the design process. These experiments may be supported by design representations inspired by......IT is rapidly spreading to non-desktop environments, and is increasingly being used for post-functional purposes. Recent contributions within the field of interaction design have indicated a tight coupling between physico-spatial and experiential issues, both on a technological and on a theoretical...

  10. The SantaBot experiment

    Hansen, Søren Tranberg; Svenstrup, Mikael; Andersen, Hans Jørgen;

    2009-01-01

    The video shows how an autonomous mobile robot dressed as Santa Claus is interacting with people in a shopping mall. The underlying hypothesis is that it is possible to create interesting new living spaces and induce value in terms of experiences, information or economics, by putting socially...... interactive mobile agents into public urban transit area. To investigate the hypothesis, an experiment was carried out using a robot capable of navigating autonomously based on the input of an onboard laser scanner. The robot would detect and follow random people, who afterwards were asked to fill out...... a questionnaire for quantitative analysis of the experiment. The presented video is the corresponding video documentation of the experiment used in the evaluation. The results showed that people were generally positive towards having mobile robots in this type of environment where shopping is combined...

  11. Cavitation Nuclei: Experiments and Theory

    Mørch, Knud Aage

    2009-01-01

    The Swedish astrophysicist and Nobel Prize winner Hannes Alfven said: Theories come and go - the experiment is here forever. Often a theory, which we set up to describe an observed physical phenomenon, suffers from the lack of knowledge of decisive parameters, and therefore at best the theory...... becomes insufficient. Contrary, the experiment always reveals nature itself, though at prevailing experimental conditions. With essential parameters being out of control and even maybe unidentified, apparently similar experiments may deviate way beyond our expectations. However, these discrepancies offer...... us a chance to reflect on the character of the unknown parameters. In this way non-concordant experimental results may hold the key to the development of better theories - and to new experiments for the testing of their validity. Cavitation and cavitation nuclei are phenomena of that character....

  12. LHCb: Self managing experiment resources

    Stagni, F

    2013-01-01

    Within this paper we present an autonomic Computing resources management system used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware addressed such issues. With a renewed Central Information Schema hosting all resources metadata and a Status System ( Resource Status System ) delivering real time informatio...

  15. Frustration: A common user experience

    Hertzum, Morten

    2010-01-01

    The use of computer applications can be a frustrating experience. This study replicates previous studies of the amount of time users – involuntarily – spend trying to diagnose and recover from problems they encounter while using computer applications such as web browsers, email, and text processing....... In the present study, 21 users self-reported their frustrating experiences during an average of 1.72 hours of computer use. As in the previous studies the amount of time lost due to frustrating experiences was disturbing. The users spent 16% of their time trying to fix encountered problems and...... another 11% of their time redoing lost work. Thus, the frustrating experiences accounted for a total of 27% of the time, This main finding is exacerbated by several supplementary findings. For example, the users were unable to fix 26% of the experienced problems, and they rated that the problems recurred...

  16. The OPERA experiment: current status

    Full text: The neutrino flavour oscillations hypothesis has been confirmed by several experiments, all are based on the observation of the disappearance of a given neutrino flavour. The long baseline neutrino experiment OPERA (Oscillation Project with Emulsion tRacking Apparatus) aims to give the first direct proof of the tau neutrino appearance in a pure muon neutrino beam (CERN neutrinos to Gran Sasso beam). The neutrino interactions in the detector are recorded by Emulsion Cloud Chambers (ECC), stacks of 57 nuclear emulsions interleaved with 1 mm thick lead plates. In 2008 the OPERA experiment has started full data taking in the CNGS beam and around 1700 interactions in the detector have been recorded. After a description of the experiment and the data taking procedure, a review of the current status and preliminary results from 2008 run will be presented. (author)

  17. Occupational Experience, Mobility, and Wages

    Groes, Fane

    In this paper we present how occupational tenure relates to wage growth and occupational mobility in Danish data. We show that the Danish data produces qualitatively similar results as found in U.S. data with respect to an increase in average wages when experience in an occupation increases. In a...... sample of full time private employed, the first five years of experience in an occupation increases average wages with 8% to 15%, conditional on rm and industry tenure. We further show that the probability of switching occupation declines with experience in the occupation and that the declining hazard...... also is true for workers switching occupation and rm. After ve years of experience in an occupation the average probability of switching any type of occupation, including occupation and rm switches, has fallen from 25% to 12%....
