    International Nuclear Information System (INIS)

    Applied Plasma Physics is a major sub-organizational unit of the MFE Program. It includes Fusion Plasma Theory and Experimental Plasma Research. The Fusion Plasma Theory group has the responsibility for developing theoretical-computational models in the general areas of plasma properties, equilibrium, stability, transport, and atomic physics. This group has responsibility for giving guidance to the mirror experimental program. There is a formal division of the group into theory and computational; however, in this report the efforts of the two areas are not separated since many projects have contributions from members of both. Under the Experimental Plasma Research Program, we are developing the intense, pulsed neutral-beam source (IPINS) for the generation of a reversed-field configuration on 2XIIB. We are also studying the feasibility of utilizing certain neutron-detection techniques as plasma diagnostics in the next generation of thermonuclear experiments

    International Nuclear Information System (INIS)

    The 'Applied Antineutrino Physics 2007' workshop is the fourth international meeting devoted to the opening of the neutrino physics to more applied fields, such as geophysics and geochemistry, nuclear industry, as well as the nonproliferation. This meeting highlights the world efforts already engaged to exploit the single characteristics of the neutrinos for the control of the production of plutonium in the civil nuclear power reactor. The potential industrial application of the measurement of the thermal power of the nuclear plants by the neutrinos is also approached. earth neutrinos were for the first time highlighted in 2002 by the KamLAND experiment. Several international efforts are currently underway to use earth neutrinos to reveal the interior of the Earth. This meeting is an opportunity to adapt the efforts of detection to the real needs of geophysicists and geochemists (sources of radiogenic heat, potassium in the court, feathers.) Finally more futuristic topics such as the detection of nuclear explosions, of low powers, are also discussed. This document gathers only the slides of the presentations

  8. Photonics applied to nuclear physics

    International Nuclear Information System (INIS)

    This was the second workshop held at the Council of Europe in the Nucleophot series. Its purpose was to bring together specialists from the fields of photonics and nuclear physics to discuss the application of modern optical techniques to current problems in experimental nuclear or particle physics research. Two techniques are particularly relevant and offer the possibility of major progress in the detection of extremely short-lived particles: holographic imaging of particle tracks and the development of scintillating-optical-fibre detectors. The discussions were mainly concerned with (a) the applications of holography to the large bubble chambers operating at Fermilab and (b) the development of high-resolution fibre-optic systems into high-rate microvertex detectors using scintillating core glass for both fixed-target and collider experiments in Europe and the USA.

    2016-01-01

    Gauge concept evolves in the course of nearly one century from Faraday’s rather obscure electrotonic state of matter to the physically significant Yang-Mills that underpin today’s standard model. As gauge theories improve, links are established with modern observations, e.g. in the Aharonov-Bohm effect, the Pancharatnam-Berry’s phase, superconductivity, and quantum Hall effects. In this century, emergent gauge theory is formulated in numerous fields of applied physics like topological insulators, spintronics, and graphene. We will show in this paper the application of gauge theory in two particularly useful spin-based phenomena, namely the spin orbit spin torque and the spin Hall effect. These are important fields of study in the engineering community due to great commercial interest in the technology of magnetic memory (MRAM), and magnetic field sensors. Both spin orbit torque and spin Hall perform magnetic switching at low power and high speed. Furthermore, spin Hall is also a promising source of pure spin current, as well as a reliable form of detection mechanism for the magnetic state of a material.

  2. Fusion programs in applied plasma physics

    International Nuclear Information System (INIS)

    The objectives of the theoretical science program are: To support the interpretation of present experiments and predict the outcome of future planned experiments; to improve on existing models and codes and validate against experimental results; and to conduct theoretical physics development of advanced concepts with applications for DIII-D and future devices. Major accomplishments in FY91 include the corroboration between theory and experiment on MHD behavior in the second stable regime of operation on DIII-D, and the frequency and mode structure of toroidal Alfven eigenmodes in high beta, shaped plasmas. We have made significant advances in the development of the gyro-Landau fluid approach to turbulence simulation which more accurately models kinetic drive and damping mechanisms. Several theoretical models to explain the bifurcation phenomenon in L- to H-mode transition were proposed providing the theoretical basis for future experimental verification. The capabilities of new rf codes have been upgraded in response to the expanding needs of the rf experiments. Codes are being employed to plan for a fully non-inductive current drive experiment in a high beta, enhanced confinement regime. GA's experimental effort in Applied Physics encompasses two advanced diagnostics essential for the operation of future fusion experiments: Alpha particle diagnostic, and current and density profile diagnostics. This paper discusses research in all these topics

    2011-10-01

    After five years of significant growth and development, and with the Impact Factor (IF) now firmly placed over 2.0, Journal of Physics D: Applied Physics (JPhysD) has seen a double change at the helm in the last 12 months. Giorgio Margaritondo from École Polytechnique Fédérale de Lausanne, Switzerland took over as Editor-in-Chief from Pallab Bhattacharya, while Olivia Roche took over as Publisher from Sarah Quin. We inherited a strong, successful journal. With its IF of 2.105, excellent publication times and flexible, responsive management, JPhysD has established itself as the place to publish high-quality research papers in applied physics. Having introduced Fast Track Communications (FTCs) in 2008, we also became an outlet for short, high-impact letter-like articles. FTCs, with their particularly strict refereeing, add an extra mark of quality to the content. We are keen to continue developing and strengthening the journal to make it the first choice for authors and readers. We are lucky to be working in the exciting, rapidly-changing field of applied physics. The pace of development can sometimes be breathtaking. One of our first actions on taking over the journal was to look again at its scope. We felt it was time to respond to all the recent developments, to ensure that our scope encompasses the latest, cutting-edge research topics—so that it matches the reality of applied physics today. The first issue of the journal that will see this new scope implemented will be issue 41 of this volume. We would like to thank the entire Editorial Board for their hard work during this scope review. The greatest change during this review has been the merging of two sections, 'Functional surfaces and interfaces' and 'Structure and properties of matter', into a new section entitled 'Condensed matter, interfaces and related nanostructures'. This change reflects the significant developments in these connected fields in recent years, particularly the natural evolution of

    1995-10-01

    Since the advent of the 800-MeV proton linear accelerator over 3 decades ago, the facilities on the Clinton P. Anderson Meson Physics Facility (LAMPF) mesa have pioneered many developments that provide unique capabilities within the Department of Energy (DOE) complex and in the world. New technologies based on the use of the world`s most intense, medium-energy linac, LAMPF, are being developed. They include destruction of long-lived components of nuclear waste, plutonium burning, energy production, production of tritium, and experiments for the science-based stockpile stewardship (SBSS) program. The design, assessment, and safety analysis of potential facilities involve the understanding of complex combinations of nuclear processes, which in turn establish new requirements on nuclear data that transcend the traditional needs of the fission and fusion reactor communities. Other areas of technology such as neutron and proton therapy applications are also placing new requirements on nuclear data. The proposed Los Alamos Neutron Science Center (LANSCE) now under discussion combined with the appropriate instrumentation will have unique features and capabilities of which there were previously only aspirations.

    2005-01-01

    This special issue of Physica Scripta contains papers presented at the 1st International Meeting on Applied Physics (APHYS-2003), held in Badajoz (Spain), from 13th to 18th October 2003, and more specifically, selected papers presented during the conference sessions mainly on Applied Optics, Laser Physics, Ultrafast Phenomena, Optical Materials, Semiconductor Materials and Devices, Optoelectronics, Quantum Electronics and Applied Solid State Physics-Chemistry. APHYS-2003 was born as an attempt to create a new international forum on Applied Physics in Europe. Since Applied Physics is not really a branch of Physics, but the application of all the branches of Physics to the broad realms of practical problems in Science, Engineering and Industry, this conference was a truly multi and inter-disciplinary event. The organizers called for papers relating Physics with other sciences such as Biology, Chemistry, Information Science, Medicine, etc, or relating different Physics areas, and aimed at solving practical problems. In other words, the Conference was specifically interested in reports applying the techniques, the training, and the culture of Physics to research areas usually associated with other scientific and engineering disciplines. It was extremely rewarding that over 800 researchers, from over 65 countries, attended the conference, where more than 1000 research papers were presented. We feel really proud of this excellent response obtained (in number and quality), for this first edition of the conference. We are very grateful to all the members of the Organizing Committee, for the hard work done for the preparation of the Conference (which began one year before the conference start), and to the members of the International Advisory Committee, for the valuable contribution to the evaluation of submitted works. Also thank to the referees for the excellent work done in the revision of submitted papers. Finally, we would like to thank the Department of Physics of the

  3. Hygrothermal Numerical Simulation Tools Applied to Building Physics

    CERN Document Server

    Delgado, João M P Q; Ramos, Nuno M M; Freitas, Vasco Peixoto

    2013-01-01

    This book presents a critical review on the development and application of hygrothermal analysis methods to simulate the coupled transport processes of Heat, Air, and Moisture (HAM) transfer for one or multidimensional cases. During the past few decades there has been relevant development in this field of study and an increase in the professional use of tools that simulate some of the physical phenomena that are involved in Heat, Air and Moisture conditions in building components or elements. Although there is a significant amount of hygrothermal models referred in the literature, the vast majority of them are not easily available to the public outside the institutions where they were developed, which restricts the analysis of this book to only 14 hygrothermal modelling tools. The special features of this book are (a) a state-of-the-art of numerical simulation tools applied to building physics, (b) the boundary conditions importance, (c) the material properties, namely, experimental methods for the measuremen...

  4. Industrial metrology as applied to large physics experiments

    International Nuclear Information System (INIS)

    A physics experiment is a large complex 3-D object (typ. 1200 m3, 35000 tonnes), with sub-millimetric alignment requirements. Two generic survey alignment tasks can be identified; first, an iterative positioning of the apparatus subsystems in space and, second, a quantification of as-built parameters. The most convenient measurement technique is industrial triangulation but the complexity of the measured object and measurement environment constraints frequently requires a more sophisticated approach. To enlarge the ''survey alignment toolbox'' measurement techniques commonly associated with other disciplines such as geodesy, applied geodesy for accelerator alignment, and mechanical engineering are also used. Disparate observables require a heavy reliance on least squares programs for campaign pre-analysis and calculation. This paper will offer an introduction to the alignment of physics experiments and will identify trends for the next generation of SSC experiments

  5. Applying high-energy physics instrumentation to environmental restoration

    International Nuclear Information System (INIS)

    Solving problems in High Energy and Nuclear Physics is only exciting to physicists. The average citizen couldn't care less, as long as it only requires a very small portion of the tax dollar. However, media have convinced the average citizen that catastrophic proportions of the environment are being destroyed and that no expenditure of funds to ameliorate these problems should ever be questioned. This communication will deal with the application of instruments originally designed for executing physics experiments to the characterization, monitoring, and restoration of contaminated environments. Detectors developed to track particles in supercollider experiments are being used to clean up uranium contaminated soils at a processing facility, detectors used to analyze the soil on Mars are being used to characterize effluents from chemical waste landfills, and detectors developed to measure lepton nonconserving double-beta decay processes are being used to measure fallout from nuclear weapons-testing. In nearly all cases where physics experiments are being applied to environmental problems, the major virtue of the original detectors was their ability or design to measure the open-quote needle in a haystack.close-quote These unique measurement capabilities have proven to be invaluable in performing unique, cost effective measurements in difficult environmental circumstances. Discussions will include applications of alpha, beta, gamma, neutron, and charged particle detectors to environments ranging from macadamia nuts contaminated with Chernobyl fallout to management of high-level liquid radioactive waste tanks. Perhaps physicists should begin to capitalize on positive public relations for their contribution to solving these high visibility problems, or perhaps they should learn to design equipment for these well-funded programs which can alternatively be used to make measurements in the mundane regions nuclear physics, astrophysics, and cosmology

  6. Applying physical layer network coding in wireless networks

    CERN Document Server

    Shengli, Zhang

    2009-01-01

    A main distinguishing feature of a wireless network compared with a wired network is its broadcast nature, in which the signal transmitted by a node may reach several other nodes, and a node may receive signals from several other nodes, simultaneously. Rather than a blessing, this feature is treated more as an interference-inducing nuisance in most wireless networks today (e.g., IEEE 802.11). This paper shows that the concept of network coding can be applied at the physical layer to turn the broadcast property into a capacity-boosting advantage in wireless ad hoc networks. Specifically, we propose a physical-layer network coding (PNC) scheme to coordinate transmissions among nodes. In contrast to "straightforward" network coding which performs coding arithmetic on digital bit streams after they have been received, PNC makes use of the additive nature of simultaneously arriving electromagnetic (EM) waves for equivalent coding operation. And in doing so, PNC can potentially achieve 100% and 50% throughput incre...

  7. Physics and agriculture: applied optics to plant fertilization and breeding

    Diomandé, K.; Soro, P. A.; Zoro, G. H.; Krou, V. A.

    2011-08-01

    The economy of Côte d'Ivoire rests on the agriculture. In order to contribute to the development of this agriculture, we have oriented our research field on applied optics to agriculture. Then, our research concerns mainly the Laser Induced chlorophyll fluorescence in plants. A simple laser-induced fluorescence set up has been designed and built at the Laboratory of Crystallography and Molecular Physics (LaCPM) at the University of Cocody (Abidjan, COTE D'IVOIRE). With this home set up we first have studied the fluorescence spectra of the "chlorophyll" to characterize the potassium deficiency in oil palm (Elaeis guineensis Jacq,). However, we found that the results differed for samples along terraced plots. The study of this phenomenon called "border effect", has enabled us to realize that sampling should be done after two rows of safety in each plot. We also applied the Laser Induced chlorophyll fluorescence technique to improve the plant breeding. For this, we have characterized the rubber tree seedlings in nurseries. And so we have highlighted those sensible to drought and resistant ones.

  8. Applying cluster analysis to physics education research data

    Science.gov (United States)

    Springuel, R. Padraic

    One major thrust of Physics Education Research (PER) is the identification of student ideas about specific physics concepts, both correct ideas and those that differ from the expert consensus. Typically the research process of eliciting the spectrum of student ideas involves the administration of specially designed questions to students. One major analysis task in PER is the sorting of these student responses into thematically coherent groups. This process is one which has previously been done by eye in PER. This thesis explores the possibility of using cluster analysis to perform the task in a more rigorous and less time-intensive fashion while making fewer assumptions about what the students are doing. Since this technique has not previously been used in PER, a summary of the various kinds of cluster analysis is included as well as a discussion of which might be appropriate for the task of sorting student responses into groups. Two example data sets (one based on the Force and Motion Conceptual Evaluation (DICE) the other looking at acceleration in two-dimensions (A2D) are examined in depth to demonstrate how cluster analysis can be applied to PER data and the various considerations which must be taken into account when doing so. In both cases, the techniques described in this thesis found 5 groups which contained about 90% of the students in the data set. The results of this application are compared to previous research on the topics covered by the two examples to demonstrate that cluster analysis can effectively uncover the same patterns in student responses that have already been identified.

    Lawrence Livermore National Laboratory, Livermore, California, USA. The physics basis of the initial flux configurations producible by the newly installed bias coils in SSPX is elucidated, and the anticipated results are explored. Broadly, the new configurations should increase the helicity injection rate, reduce the proportion of the spheromak flux that intersects the material boundary (‘field errors’) and increase particle confinement time. The effect of the applied field on equilibrium (CORSICA in SSPX geometry[1]) and stability (DCON[2]) will be discussed. Also, the effects on the dominant modes will be explored through 3D resistive MHD simulation (NIMROD[3]). Finally, a means for sustaining the spheromak in the absence of the n=1 mode, thought to be necessary for current drive, will be examined. [1] Hooper et al Nuc.

    International Nuclear Information System (INIS)

    The activities of the Division during 1984/85 were again directed towards the general program objectives of the past two years. A shift in emphasis resulted in some organization changes. The increased importance of nuclear safeguards research in the Government's support for the International Atomic Energy Agency program has prompted a re-arrangement of the nuclear physics and science activities. Dr JR. Bird holds the responsibility for the Nuclear Science Section comprising the Nuclear Applications Group, Biomedical and Reactor Applications Group and the Neutron Scattering Group. The newly formed Safeguards and Nuclear Physics Section is headed by Dr J.W. Boldeman and includes the Safeguards Group and Nuclear Physics Group. The organization of the remainder of the Division is unchanged. The work on the electronic properties of hydrogen in silicon has been particularly rewarding and the plasma physics studies received recognition with an IAEA sponsored workshop on Compact Torus Research held in Sydney in March 1985 (author)

  17. The Stirling Engine-Refrigerator Rich Pedagogy from Applied Physics

    CERN Document Server

    Peters, R D

    2001-01-01

    A Stirling engine of the type used for demonstration purposes has been outfitted with a pair of sensors that measure pressure and piston displacement when the engine is operating with a small temperature difference between the hot and cold reservoirs. Measured variables are compared against computer generated output based on a simple theory that involves nonlinear equations of motion. Theory and experiment are found to be in reasonable agreement. Temperature dependence of the graph of pressure versus piston displacement, for different directions of flywheel rotation, permits a better understanding of the physics of heat engines and refrigerators in general.

  18. Modeling Organizational Design - Applying A Formalism Model From Theoretical Physics

    Directory of Open Access Journals (Sweden)

    Robert Fabac

    2008-06-01

    Full Text Available Modern organizations are exposed to diverse external environment influences. Currently accepted concepts of organizational design take into account structure, its interaction with strategy, processes, people, etc. Organization design and planning aims to align this key organizational design variables. At the higher conceptual level, however, completely satisfactory formulation for this alignment doesn’t exist. We develop an approach originating from the application of concepts of theoretical physics to social systems. Under this approach, the allocation of organizational resources is analyzed in terms of social entropy, social free energy and social temperature. This allows us to formalize the dynamic relationship between organizational design variables. In this paper we relate this model to Galbraith's Star Model and we also suggest improvements in the procedure of the complex analytical method in organizational design.

  19. Statistical physics applied to stone-age civilization

    CERN Document Server

    Sumour, M A; Shabat, M M; El-Astal, Ali H

    2011-01-01

    About 45,000 years ago, symbolic and technological complexity of human artefacts increased drastically. Computer simulations of Powell, Shennan and Thomas (2009) explained it through an increase of the population density, facilitating the spread of information about useful innovations. We simplify this demographic model and make it more similar to standard physics models. For this purpose, we assume that bands (extended families) of stone-age humans were distributed randomly on a square lattice such that each lattice site is randomly occupied with probability p and empty with probability 1-p. Information spreads randomly from an occupied site to one of its occupied neighbours. If we wait long enough, information spreads from one side of the lattice to the opposite site if and only if p is larger than the percolation threshold; this process was called "ant in the labyrinth" by deGennes 1976. We modify it by giving the diffusing information a finite lifetime, which shifts the threshold upwards.

  1. Industrial safety and applied health physics. Annual report, 1979

    International Nuclear Information System (INIS)

    In connection with personnel monitoring, there were no external or internal exposures to personnel which exceeded the standards for radiation protection as defined in DOE Manual Chapter 0524. Only 55 employees received whole-body dose equivalent of one rem or greater. The highest whole-body dose equivalent to an employee was 2.8 rem. The highest internal exposure was less than one-half of a maximum permissible dose for any calendar quarter. During 1979, 57 portable health physics instruments were added to the inventory and 75 retired. The total number in service on January 1, 1979, was 977. With regards to environmental monitoring, there were no releases of gaseous waste from the Laboratory which were of a level that required an incident report to DOE. There were no releases of liquid radioactive waste from the Laboratory which were of a level that required an incident report to DOE. Soil samples were collected at all perimeter and remote monitoring stations and analyzed for eleven radionuclides including plutonium and uranium. Plutonium-239 content ranged from 0.01 to 0.06 pCi/g, and the uranium-235 content ranged from 0.01 to 0.05 pCi/g. Grass samples were collected at all perimeter and remote monitoring stations and analyzed for twelve radionuclides including plutonium and uranium. Plutonium-239 content ranged from 0.001 to 0.010 pCi/g, and uranium-235 content ranged from 0.001 to 0.010 pCi/g. Two radiation incidents involving radioactive materials were recorded during 1979.

  9. Can we build a more efficient airplane? Using applied questions to teach physics

    Science.gov (United States)

    Bhatia, Aatish

    2014-03-01

    For students and for the science-interested public, applied questions can serve as a hook to learn introductory physics. Can we radically improve the energy efficiency of modern day aircraft? Are solar planes like the Solar Impulse the future of travel? How do migratory birds like the alpine swift fly nonstop for nearly seven months? Using examples from aeronautical engineering and biology, I'll discuss how undergraduate physics can shed light on these questions about transport, and place fundamental constraints on the flight properties of flying machines, whether birds or planes. Education research has shown that learners are likely to forget vast content knowledge unless they get to apply this knowledge to novel and unfamiliar situations. By applying physics to real-life problems, students can learn to build and apply quantitative models, making use of skills such as order of magnitude estimates, dimensional analysis, and reasoning about uncertainty. This applied skillset allows students to transfer their knowledge outside the classroom, and helps build connections between traditionally distinct content areas. I'll also describe the results of an education experiment at Rutgers University where my colleagues and I redesigned a 100+ student introductory physics course for social science and humanities majors to address applied questions such as evaluating the energy cost of transport, and asking whether the United States could obtain all its energy from renewable sources.

  10. Verification, Validation, and Solution Quality in Computational Physics: CFD Methods Applied to Ice Sheet Physics

    Thompson, David E.

    2005-01-01

    Procedures and methods for veri.cation of coding algebra and for validations of models and calculations used in the aerospace computational fluid dynamics (CFD) community would be ef.cacious if used by the glacier dynamics modeling community. This paper presents some of those methods, and how they might be applied to uncertainty management supporting code veri.cation and model validation for glacier dynamics. The similarities and differences between their use in CFD analysis and the proposed application of these methods to glacier modeling are discussed. After establishing sources of uncertainty and methods for code veri.cation, the paper looks at a representative sampling of veri.cation and validation efforts that are underway in the glacier modeling community, and establishes a context for these within an overall solution quality assessment. Finally, a vision of a new information architecture and interactive scienti.c interface is introduced and advocated.

    Now it has become a fashion in our society that young learners aged from 6 or even younger participate in foreign language learning.With the Second Language Acquisition theories,it is believed that learning a foreign language from the childhood can facilitate the learning.Children need a teaching method which conforms to their psychological and physical characteristics.American psychologist James Asher develops Total Physical Response,which advocates leaning through physical actions.He believes that children should learn a foreign language happily and confidently,just like the process of acquiring their mother tongue.However,Total Physical Response can not be applied effectively in the teaching process due to children’s instincts and characteristics.If there is a way or strategy which takes advantage of children’s characteristics and control their behavior in class,the teaching results would be more satisfying.

    Although it is common practice to borrow tools from mathematics to apply to physics or music, it is unusual to use tools developed in music theory to mathematically describe physical phenomena. So called ``Maximally Even Set'' theory fits this unusual case. In this poster, we summarize, by example, the theory of Maximally Even (ME) sets and show how this formalism leads to the distribution of black and white keys on the piano keyboard. We then show how ME sets lead to a generalization of the well-known ``Cycle-of-Fifths'' in music theory. Subsequently, we describe ordering in one-dimensional spin-1/2 anti-ferromagnets using ME sets showing that this description leads to a fractal ``Devil's Staircase'' magnetic phase diagram. Finally, we examine an extension of ME sets, ``Iterated Maximally Even'' sets that describes chord structure in music.

    2008-01-01

    Labels and tags are accompanying us in almost each moment of our life and everywhere we are going, in the form of electronic keys or money, or simply as labels on products we are buying in shops and markets. The label diffusion, rapidly increasing for logistic reasons in the actual global market, carries huge amount of information but it is demanding security and anti-fraud systems. The first crucial point, for the consumer and producer safety, is to ensure the authenticity of the labelled products with systems against counterfeiting and piracy. Recent anti-fraud techniques are based on a sophisticated use of physical effects, from holograms till magnetic resonance or tunnel transitions between atomic sublevels. In this paper we will discuss labels and anti-fraud technologies as a new and very promising research field for applied physics.

  17. Quantitative seismic interpretation: Applying rock physics tools to reduce interpretation risk

    2007-01-01

    @@ Seismic data analysis is one of the key technologies for characterizing reservoirs and monitoring subsurface pore fluids. While there have been great advances in 3D seismic data processing, the quantitative interpretation of the seismic data for rock properties still poses many challenges. This book demonstrates how rock physics can be applied to predict reservoir parameters, such as lithologies and pore fluids, from seismically derived attributes, as well as how the multidisciplinary combination of rock physics models with seismic data, sedimentological information, and stochastic techniques can lead to more powerful results than can be obtained from a single technique.

    2015-10-01

    Disagreement of reactor antineutrino spectrum and flux measurements with updated predictions indicates that we have much to learn about the complicated processes underlying antineutrino production in reactors, as well as hinting at new physics. A number of new efforts seek to address these questions, including the PROSPECT experiment planned at the HFIR research reactor. In addition to greatly advancing our understanding of reactor antineutrino emissions, PROSPECT can support a rich applied physics program. The detection technology developed for PROSPECT will enable precision antineutrino spectrum measurements close to essentially any reactor type. Here we describe how such measurements provide opportunities to probe fissile isotope and fission daughter distributions, and their potential use for reactor physics and safeguards applications.

    Since 1946, the Japan Society of Applied Physics (JSAP) has strived to promote research and development in applied physics for benefits beyond national boundaries. Activities of JSAP involve multidisciplinary fields, from physics and engineering to life sciences. Of its 23,000 members, 48% are from industry, 29% from academia, and about 7% from semi-autonomous national research laboratories. Its large industrial membership is one of the distinctive features of JSAP. In preparation for the First IUPAP International Conference on Women in Physics (Paris, 2002), JSAP members took the first step under the strong leadership of then-JSAP President Toshio Goto, setting up the Committee for the Promotion Equal Participation of Men and Women in Science and Technology. Equality rather than women's advancement is highlighted to further development in science and technology. Attention is also paid to balancing the number of researchers from different age groups and affiliations. The committee has 22 members: 12 female and 10 male; 7 from corporations, 12 from universities, and 3 from semi-autonomous national research institutes. Its main activities are to organize symposia and meetings, conduct surveys among JSAP members, and provide child-care facilities at meetings and conferences. In 2002 the Japan Physics Society and the Chemical Society of Japan jointly created the Japan Inter-Society Liaison Association for the Promotion of Equal Participation of Men and Women in Science and Engineering. Membership has grown to 44 societies (of which 19 are observers) ranging from mathematics, information, and life sciences to civil engineering. Joint activities across sectors and empower the whole. The Gender Equality Bureau in the Cabinet Office recently launched a large-scale project called "Challenge Campaign" to encourage girls to major in natural science and engineering, which JSAP is co-sponsoring.

    Kolagani, Rajeswari

    It is a well-established fact that the scientific knowledge and skills acquired in the process of obtaining a degree in physics meet the needs of a variety of positions in multiple science and technology sectors. However, in addition to scientific competence, challenging careers often call for skills in advanced communication, leadership and team functions. The professional science master's degree, which has been nick-named as the `Science MBA', aims at providing science graduates an edge both in terms of employability and earning levels by imparting such skills. Our Professional Science Master's Program in Applied Physics is designed to develop these `plus' skills through multiple avenues. In addition to advanced courses in Applied Physics, the curriculum includes graduate courses in project management, business and technical writing, together with research and internship components. I will discuss our experience and lessons learned over the 5 years since the inception of the program in 2010.

    Fusion tokamaks are complex devices requiring many diagnostics for real time control of the plasma and off-line physical analysis. In current tokamaks, imaging diagnostics have become increasingly used for these two purposes. Such systems produce a lot of data encouraging physicists to use shared tools and codes for data access and analysis. If general purpose software programs for data display and analysis are widely spread, a need exists in developing similar applications for quantitative imaging data analysis applied to plasma physic. In this paper, we introduce a new integrated software program, named WOLFF, dedicated to this task. The main contribution of this software is to gather under the same framework different functionalities for (1) data access and display, (2) signal, image, and video processing, and (3) quantitative analysis based on physical models. After an overview of existing solutions for data processing in the field of plasma data, we present the WOLFF architecture and its currently implemented features. The capabilities of the software are then demonstrated through three applications in the field of physical analysis (heat and particle flux calculations) and tokamak operational safety.

    2013-01-01

    Teaching Assistants (TAs) play an important role in supporting research-based instructional environments, yet the connection between TAs' pedagogical beliefs and instructional practices is not well understood. We build upon a broad foundation of research on the nature of pedagogical content knowledge to develop an analytic framework for characterizing how physics TAs both describe and enact their roles as teachers. In a previous work [1], we started developing a framework for TA pedagogical beliefs and highlighted examples of emergent differences between TAs along one particular dimension, agency. In this paper, we extend this framework to include TAs' instructional goals, and their methods and purpose of assessment. Using examples drawn from several semesters of interviews and classroom videotape, we apply this framework and describe instances of both strong and weak coordination between TA beliefs and practices.

    1996-07-01

    This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Group theoretical methods are a powerful tool both in their applications to mathematics and to physics. The broad goal of this project was to use such methods to develop the implications of group (symmetry) structures underlying models of physical systems, as well as to broaden the understanding of simple models of chaotic systems. The main thrust was to develop further the complex mathematics that enters into many-particle quantum systems with special emphasis on the new directions in applied mathematics that have emerged and continue to surface in these studies. In this area, significant advances in understanding the role of SU(2) 3nj-coefficients in SU(3) theory have been made and in using combinatoric techniques in the study of generalized Schur functions, discovered during this project. In the context of chaos, the study of maps of the interval and the associated theory of words has led to significant discoveries in Galois group theory, to the classification of fixed points, and to the solution of a problem in the classification of DNA sequences.

  20. Value of the physical basis of equivalent uniform dose as applied to intensity modulated radiation therapy

    International Nuclear Information System (INIS)

    Objective: To study the mathematic and physical basis of the equivalent uniform dose (EUD) and its optimization mechanism in the control of dose distribution in the organs at risk (OAR) and targets in IMRT optimization process, as well as its significance in clinical application. Methods: The mathematic limit analysis method and MATLAB mathematic analysis software were applied to observe the consistence with two different methods. The results of all formulae introduced by Niemierko were compared with the numerical value directly computed. The optimization mechanism of the dose distribution in the target/OAR in IMRT optimization process on the base of 2 units most simplified EUD optimization analysis model was studied. Results: When parameter α tends to + ∞, -∞, 0 and 1, the result of EUD directly computed on the MATLAB mathematic analysis software was similar to that relied on the limit analysis on condition, which provided evidence for experience that we should apply a positive value to OAR and a negative value to targets. By giving a suitable parameter 'α' and 'n', we may get a better target coverage and improve the sparing of critical structures through small number of iterations while using multiple dose-volume constrains for each anatomic structure and with considering great trial-and-error to adjust a larger number of objective function parameters, all of which were helpful to improve the target control probability and reduce the normal tissue complication probability. Conclusions: The use of parameter 'α' does significantly influence the optimization results on EUD based optimization method for patients with head and neck cancer and prostate cancer. Meanwhile, the EUD based optimization method has significant advantages in aspects of optimization results and optimization efficiency when compared with DVH based optimization, which does have greater significance in clinical application.

  2. Computational physics and applied mathematics capability review June 8-10, 2010

    Energy Technology Data Exchange (ETDEWEB)

    Lee, Stephen R [Los Alamos National Laboratory

    2010-01-01

    Los Alamos National Laboratory will review its Computational Physics and Applied Mathematics (CPAM) capabilities in 2010. The goals of capability reviews are to assess the quality of science, technology, and engineering (STE) performed by the capability, evaluate the integration of this capability across the Laboratory and within the scientific community, examine the relevance of this capability to the Laboratory's programs, and provide advice on the current and future directions of this capability. This is the first such review for CPAM, which has a long and unique history at the Laboratory, starting from the inception of the Laboratory in 1943. The CPAM capability covers an extremely broad technical area at Los Alamos, encompassing a wide array of disciplines, research topics, and organizations. A vast array of technical disciplines and activities are included in this capability, from general numerical modeling, to coupled multi-physics simulations, to detailed domain science activities in mathematics, methods, and algorithms. The CPAM capability involves over 12 different technical divisions and a majority of our programmatic and scientific activities. To make this large scope tractable, the CPAM capability is broken into the following six technical 'themes.' These themes represent technical slices through the CPAM capability and collect critical core competencies of the Laboratory, each of which contributes to the capability (and each of which is divided into multiple additional elements in the detailed descriptions of the themes in subsequent sections), as follows. Theme 1: Computational Fluid Dynamics - This theme speaks to the vast array of scientific capabilities for the simulation of fluids under shocks, low-speed flow, and turbulent conditions - which are key, historical, and fundamental strengths of the Laboratory.

  4. Physical factors affecting single photon emission computed tomography (SPECT) applied in nuclear medicine

    International Nuclear Information System (INIS)

    many physical factors degrade single photon emission computed tomography (SPECT) images both qualitatively and quantitatively. Physical properties important for the assessment of the potential of emission computed tomography implemented by collimated detector systems include sensitivity, statistical and angular sampling requirements, attenuation compensation, resolution, uniformity, and multisection design constraints. SPECT has highlighted the used to improve gamma camera performance. Flood field nonuniformity is translated into tomographic the need to improve gamma camera performance. Flood field nonuniformity is translated into tomographic images as major artifacts because it distorts the data obtained at each projection. Also, poor energy resolution translates directly into degraded spatial resolution through reduced ability to reject scattered photons on the basic of pluses height analysis. The aim of this work is study the different and most important acquisition and processing parameters, which affect the quality of the SPECT images. The present study investigates the various parameters effecting SPECT images and experimental results demonstrate that: daily uniformity checks and evaluation are essential to ensure that the SPECT system is working properly. The Core used in the reconstruction process could be correct to avoid data misalignment. 60 mumblers of views gave the best image quality, rather than 20 or 30 views. Time per view (TPV) 30 or 20 sec gave a good image quality, rather than high-resolution collimator, is recommended in order to provide good spatial resolution. On the other hand patient motion could cause serious reconstruction artifacts. A cine display is recommended to identify movement artifacts. In the case of matrix size, matrix 128x128 give the best resolution than matrix 64x64. Energy window width, 15% compared with the standard 20% improved the resolution. Butter worth filter (cut off 0.57 cyc/cm with order 6 ) give the best resolution

  5. Closing the gap between ethics knowledge and practice through active engagement: an applied model of physical therapy ethics.

    Delany, Clare M; Edwards, Ian; Jensen, Gail M; Skinner, Elizabeth

    2010-07-01

    Physical therapist practice has a distinct focus that is holistic (ie, patient centered) and at the same time connected to a range of other providers within health care systems. Although there is a growing body of literature in physical therapy ethics knowledge, including clinical obligations and underlying philosophical principles, less is known about the unique ethical issues that physical therapists encounter, and how and why they make ethical decisions. As moral agents, physical therapists are required to make autonomous clinical and ethical decisions based on connections and relationships with their patients, other health care team members, and health institutions and policies. This article identifies specific ethical dimensions of physical therapist practice and highlights the development and focus of ethics knowledge in physical therapy over the last several decades. An applied ethics model, called the "active engagement model," is proposed to integrate clinical and ethical dimensions of practice with the theoretical knowledge and literature about ethics. The active engagement model has 3 practical steps: to listen actively, to think reflexively, and to reason critically. The model focuses on the underlying skills, attitudes, and actions that are required to build a sense of moral agency and purpose within physical therapist practice and to decrease gaps between the ethical dimensions of physical therapist practice and physical therapy ethics knowledge and scholarship. A clinical case study is provided to illustrate how the ethics engagement model might be used to analyze and provide insight into the ethical dimensions of physical therapist practice. PMID:20448105

  7. How can we improve problem-solving in undergraduate biology? Applying lessons from 30 years of physics education research

    CERN Document Server

    Hoskinson, Anne-Marie; Knight, Jennifer K

    2012-01-01

    Modern biological problems are complex. If students are to successfully grapple with such problems as scientists and citizens, they need to have practiced solving authentic, complex problems during their undergraduate years. Physics education researchers have investigated student problem-solving for the last three decades. Although the surface features and content of biology problems differ from physics problems, teachers of both sciences want students to learn to explain patterns and processes in the natural world and to make predictions about system behaviors. After surveying literature on problem-solving in physics and biology, we propose how biology education researchers could apply research-supported pedagogical techniques from physics to enhance biology students' problem-solving. First, we characterize the problems that biology students are typically asked to solve. We then describe the development of research-validated physics problem-solving curricula. Finally, we propose how biology scholars can appl...

    Background: A sedentary life without sufficient physical activity is recognized as a risk factor for various diseases, and a major modifiable risk factor for noncommunicable diseases. This study was conducted to investigate the effect of intervention using socioecological model in promoting women’s physical activity in the city of Kerman, Iran. Materials and Methods: In this randomized, double-blinded, controlled study, 360 women were studied at health and medical centers of Kerman. This educational intervention was based on socioecological model and conducted on 4 levels of personal, social, organizational, and political. Data collection tool included a researcher-made questionnaire based on constructs of socioecological model and the international physical activity inventory. Results: The results indicated insignificant differences between the two groups in terms of perceived social, physical, and political support and also with regard to level of physical activity before intervention. However after the intervention and according to independent t test, significant differences were observed between two groups in perceived social, physical, and political support and also level of physical activity (P < 0.001). Furthermore, mean values of the above terms increased in the intervention group. Conclusions: According to the results, interventions based on socioecological model can positively affect women’s physical activity. PMID:27247781

  12. POOLkits: Applying Object Oriented Principles from Software Engineering to Physics Object Oriented Learning -- Preliminary Concepts

    Science.gov (United States)

    Kassebaum, Thomas; Aubrecht, Gordon

    2012-04-01

    Object-oriented development depends upon the creation of generic pieces that can be built into more complex parts. In physics, we begin teaching basic principles and then develop more complex systems, a fertile environment to develop learning objects. Each learning object consists of observable quantities, such as the physical properties of a block of wood, and operators that act on the object, such as force. Additionally, each object can also include an assessment operator that evaluates the impact of the learning object on student comprehension. The physics object-oriented learning kits (POOLkits) will be developed to enhance student understanding of physics concepts, as well as, build a framework for developing a software object based on the physics concept. A POOLkit can be extended, similar to the concept of extending classes in object-oriented programming, as physics knowledge expands. The expectation for these POOLkits would be to provide physics students with a solid foundation in the first principles to be able to derive more complex formulae and have the understanding of the process with a secondary benefit of enhancing the object-oriented programming capabilities of physics students.

Methods: The cases who were examined in Board of Physical and Mental Health in Forensic medicine Department of Dicle University, Faculty of Medicine were assessed retrospectively in terms of age, gender, marital status, education level, relation of the victim with the accused, presence of penetration and disruption of physical and mental health. Results: Among 258 cases, who referred to our board, 196 were female and 62 were male. The age range of the victims was 2 to 50 and average age was detected as 13.1 ± 5.9 years. It was determined that 227 (88% cases were under 18 years and 31 cases (12% were above 18 years. Vaginal and anal penetration was claimed in 48 and 61 cases, respectively; oral + anal penetration was claimed in 11 cases; both vaginal and oral penetration was claimed in two cases. Among 258 cases, 144 cases had no physical and mental disruption; 49 cases were diagnosed with mental and physical health disruption and 65 cases were followed by issuing a preliminary report. Conclusion: As a result of our study any significant relation is not found between impairment in psychological health and sex, marital status, educational level of the victim, age groups, the age difference between the victim and the defendant. Therefore, it is understood that either men or women, married or single, educated or uneducated people are affected emotionally as bad as from sexual assault. This supports the idea that, especially in cases that any findings cannot be obtained with genital and physical examination, psychological evaluation may be important.

    The statistical MCNP (Monte Carlo N-Particle) code has been satisfactorily used for reactor and radiation physics calculations to support NRU operation and analysis. MCNP enables 3D modeling of the reactor and its components in great detail, the transport calculation of photons (in addition to neutrons), and the capability to model all locations in space, which are beyond the capabilities of the deterministic neutronics methods used for NRU. While the simple single-cell model is efficient for local analysis in any site of NRU, the complex full-reactor model is required for calculations of the core physics and beyond-the-core radiation. By supplementing, adjusting or benchmarking the results from the existing NRU codes, the MCNP calculations provide greater confidence that NRU remains within the licence envelope. (author)

    Cognitive developmental psychology often describes children's growing qualitative understanding of the physical world. Physics educators may be able to use the relevant methods to advantage for characterizing changes in students' qualitative reasoning. Siegler developed the "rule assessment" method for characterizing levels of qualitative understanding for two factor situations (e.g., volume and mass for density). The method assigns children to rule levels that correspond to the degree they notice and coordinate the two factors. Here, we provide a brief tutorial plus a demonstration of how we have used this method to evaluate instructional outcomes with middle-school students who learned about torque, projectile motion, and collisions using different instructional methods with simulations.

  10. Contribution on physics measurements using a modulated source of radiations applied to nuclear plants

    International Nuclear Information System (INIS)

    In this work, measurements methods were studied with applications concerning pressurized water reactor (PWR), and reprocessing Plants. The aim of these measurements is to assess some of the characteristics of a physical medium by the use of a source of radiations (neutron or gamma) and of a convenient signal processing (averaging, Fourier transform). By using a modulation system, the Fourier transform enables us to extract the signal from the background noise (issuing either from the measurement system, either from the physical medium itself). The applications, that have been carried out, are: the measurement of the void fraction in the hot leg of a PWR by modulated gamma transmission and the measurement of the quantity of fissile material in reprocessing plants by the use of modulated source of neutron

    In this paper, we propose some of the strategies and methodologies for teaching high-school physics topics through an educational robotics show. This exhibition was part of a set of actions promoted by a Brazilian government program of incentive for teaching activities, whose primary focus is the training of teachers, the improvement of teaching in public schools, the dissemination of science, and the formation of new scientists and researchers. By means of workshops, banners and the prototyping of robotics, we were able to create a connection between the study areas and their surroundings, making learning meaningful and accessible for the students involved and contributing to their cognitive development.

    1999-01-01

    The Compact Muon Solenoid experiment, CMS, is one of the two general purpose experiments foreseen to operate at the Large Hadron Collider, LHC, at CERN, the European Laboratory for Particle Physics. The experiment aims to study very high energy collisions of proton beams. Investigation of the most fundamental properties of matter, in particular the study of the nature of the electroweak symmetry breaking and the origin of mass, is the experiment scope. The central Tracking System, a six meter long cylinder with 2.4 m diameter, will play a major role in all physics searches of the CMS experiment. Its performance depends upon the intrinsic detector performance, on the stability of the supporting structure and on the overall survey, alignment and position monitoring system. The proposed position monitoring system is based on a novel lens-less laser straightness measurement method able to detect deviations from a nominal position of all structural elements of the Central Tracking system. It is based on the recipr...

  4. Design of a multiplicity logical unit applied for multi-inclusive physical experiments

    International Nuclear Information System (INIS)

    The author briefly introduces a NIM module which can be widely used in the data acquisition system as event trigger generator, where the data of many relative parameters inclusive physical experiments are analyzed logically and selected beforehand. According to the inclusive multiplicity 'N', the module produces a NIM signal to trigger Data Acquisition System and ADC or TDC to convert the Events' data if the events' inclusive multiplicity is no less than 'N'. Otherwise, if the inclusive multiplicity is less than 'N', then the Events will be ignored. Consequently, the inclusive multiplicity as well as its distribution of the inclusive events can be known and the module makes the background computers of the data acquisition system to select and acquire the data more easily and faster. Therefore , lots of useless data and low inclusive events are excluded so as to save the expensive beam time and improve the experiment efficiency

  5. Radon applied for physical therapy - a review of the current situation

    International Nuclear Information System (INIS)

    There is no clear evidence at date that radon alone may have specific therapeutic effects, but there are results indicating specific remedial success in certain cases (Bechterev's diesease, e.g.). A major uncertainty factor in establishing a causal relationship, particularly for treatment in radon underground spas, is the presence of various therapeutic factors such as the radon, heat, and hummidity,and their probable synergistic effects. The inhalation of air free of daughter products, as is applied in the radon spas in Russia, may strongly reduce the lung cancer risk, at a comparable achievable therapeutic effect. It is the medical and the technical personnel in these spas that profit most from this reduction. The radiation dose to the patient resulting from radon treatment remains within the limits of natural background radiation. The medical and technical personel is to be (and is) protected by the radiological protection regime provided by the law. (orig./HP)

  6. The Quantum Mechanics Solver: How to Apply Quantum Theory to Modern Physics, 2nd edition

    International Nuclear Information System (INIS)

    he hallmark of a good book of problems is that it allows you to become acquainted with an unfamiliar topic quickly and efficiently. The Quantum Mechanics Solver fits this description admirably. The book contains 27 problems based mainly on recent experimental developments, including neutrino oscillations, tests of Bell's inequality, Bose-Einstein condensates, and laser cooling and trapping of atoms, to name a few. Unlike many collections, in which problems are designed around a particular mathematical method, here each problem is devoted to a small group of phenomena or experiments. Most problems contain experimental data from the literature, and readers are asked to estimate parameters from the data, or compare theory to experiment, or both. Standard techniques (e.g., degenerate perturbation theory, addition of angular momentum, asymptotics of special functions) are introduced only as they are needed. The style is closer to a non-specialist seminar rather than an undergraduate lecture. The physical models are kept simple; the emphasis is on cultivating conceptual and qualitative understanding (although in many of the problems, the simple models fit the data quite well). Some less familiar theoretical techniques are introduced, e.g. a variational method for lower (not upper) bounds on ground-state energies for many-body systems with two-body interactions, which is then used to derive a surprisingly accurate relation between baryon and meson masses. The exposition is succinct but clear; the solutions can be read as worked examples if you don't want to do the problems yourself. Many problems have additional discussion on limitations and extensions of the theory, or further applications outside physics (e.g., the accuracy of GPS positioning in connection with atomic clocks; proton and ion tumor therapies in connection with the Bethe-Bloch formula for charged particles in solids). The problems use mainly non-relativistic quantum mechanics and are organised into three

    The aim of the study was to determine the effect of different drying methods on selected physical properties of pomace obtained from purple carrot cv. Deep Purple. Drying was performed using four methods: convective, microwave-convective, infrared-convective and freeze-drying. The freeze-dried material had the lowest apparent density (422 kg m-3), which was caused by slight shrinkage, and indicated high porosity. Apparent density was almost three times greater in dried materials produced using the other drying methods as compared to the freeze-dried variants. Freeze-dried pomace adsorbed vapour more quickly than the other dried variants, which was caused by its high porosity and relatively low degree of structural damage. Rehydration characteristicswere significantly affected by the dryingmethod. The highest mass increase and losses of soluble substance were recorded for the freeze-dried samples. Conversely, the traditional convective drying method resulted in the lowest mass increase and soluble substance leaching. A positive linear correlation was found between the loss of soluble dry substance components and the absorbance of liquid obtained during rehydration.

    1997-03-01

    Many students find the transition from secondary to tertiary education difficult. White et al. (1) have considered some of the difficulties encountered by Australian students that include the change from a small personal secondary school to a large impersonal university, as well as the shift in responsibility for learning from teacher to student. The teaching strategy outlined in this paper was designed to address the latter issue by encouraging new university students to take more responsibility for their own learning. The students considered in the study were enrolled in Physics 110, a one semester non-calculus unit that is part of the Applied Science degree at La Trobe University, Bendigo, and covers a basic introduction to mechanics, SHM and wave motion, fluids and heat. The authors were the teacher/researchers for the subject, presenting both the classroom and laboratory sections to 32 students in 1995 and 14 students in 1996. All students enrolled in Physics 110 had completed Year 12 Physics (or equivalent) at secondary school.

  14. Answer first: Applying the heuristic-analytic theory of reasoning to examine student intuitive thinking in the context of physics

    2014-12-01

    We have applied the heuristic-analytic theory of reasoning to interpret inconsistencies in student reasoning approaches to physics problems. This study was motivated by an emerging body of evidence that suggests that student conceptual and reasoning competence demonstrated on one task often fails to be exhibited on another. Indeed, even after instruction specifically designed to address student conceptual and reasoning difficulties identified by rigorous research, many undergraduate physics students fail to build reasoning chains from fundamental principles even though they possess the required knowledge and skills to do so. Instead, they often rely on a variety of intuitive reasoning strategies. In this study, we developed and employed a methodology that allowed for the disentanglement of student conceptual understanding and reasoning approaches through the use of sequences of related questions. We have shown that the heuristic-analytic theory of reasoning can be used to account for, in a mechanistic fashion, the observed inconsistencies in student responses. In particular, we found that students tended to apply their correct ideas in a selective manner that supported a specific and likely anticipated conclusion while neglecting to employ the same ideas to refute an erroneous intuitive conclusion. The observed reasoning patterns were consistent with the heuristic-analytic theory, according to which reasoners develop a "first-impression" mental model and then construct an argument in support of the answer suggested by this model. We discuss implications for instruction and argue that efforts to improve student metacognition, which serves to regulate the interaction between intuitive and analytical reasoning, is likely to lead to improved student reasoning.

    Despite the physical and mental health benefits of leisure-time physical activity (LTPA), only about half of college students participate in the recommended amount of LTPA. While college students are avid users of social network sites (SNSs), whether SNSs would be an effective channel for promoting LTPA through peer social support is unclear. The aim of this study was to explore the effects of social support from students' contacts on SNSs on their intention to participate in LTPA, applying the Theory of Planned Behavior. Participants were recruited through a mass e-mail sent to undergraduate students at a large Midwestern university in fall 2011. In total, 439 surveys were analyzed. Descriptive analyses and analysis for mediating effects were conducted. Social support about LTPA from contacts on SNSs has indirect effect on intention through affective attitude, instrumental attitude, and perceived behavioral control (PBC). The results indicate that social support about LTPA from contacts on SNSs might not be effective to change students' intention unless attitudes and PBC are changed. Future interventions aiming to promote students' intention to participate in LTPA by increasing support from contacts on SNSs should increase affective attitude, instrumental attitude, and PBC at the same time.

    Chitto Tustenugee's final Seminole stronghold is now preserved in Miramar, Florida. It is profoundly active; its electromagnetic field, EMF, can be detected by methods readily accessible to the historic Seminole. They may have utilized information from it to avoid hurricanes and tornadoes. It also can yield information about future earthquakes. An anomalous earthquake 90 miles north of Guantanamo Bay, Cuba, was ``predicted'' by Mc Leod. The core concept here is that certain sites generate signals detectable by non-technologic societies, which seem to incorporate them into their world-views that include aspects of applied, practical physics. Keitan: A God, and Katahdin: Cathar stronghold, mountains in Maine, Iquitos: Island of the Cathars, is in Peru, reachable by sea-going vessels. Quito: Cathar, is in Ecuador. Caqueta: Church of the Cathar, is a tributary of the Amazon from Columbia. Chitto: Cathar, Qatar: Cathar. Is it even possible that Nepal's Katmandu, as Cathar doctor monk and Willimantic, doctor applied physicist at The God Spirit-signal, EMF, define similar individuals? What were the reasons why so many disparate groups, at different times, selected place-names or ``titles'' that have implicit, historic significance, involving natural phenomena?

  17. Radiation physics and shielding codes and analyses applied to design-assist and safety analyses of CANDUR and ACRTM reactors

    International Nuclear Information System (INIS)

    This paper discusses the radiation physics and shielding codes and analyses applied in the design of CANDU and ACR reactors. The focus is on the types of analyses undertaken rather than the inputs supplied to the engineering disciplines. Nevertheless, the discussion does show how these analyses contribute to the engineering design. Analyses in radiation physics and shielding can be categorized as either design-assist or safety and licensing (accident) analyses. Many of the analyses undertaken are designated 'design-assist' where the analyses are used to generate recommendations that directly influence plant design. These recommendations are directed at mitigating or reducing the radiation hazard of the nuclear power plant with engineered systems and components. Thus the analyses serve a primary safety function by ensuring the plant can be operated with acceptable radiation hazards to the workers and public. In addition to this role of design assist, radiation physics and shielding codes are also deployed in safety and licensing assessments of the consequences of radioactive releases of gaseous and liquid effluents during normal operation and gaseous effluents following accidents. In the latter category, the final consequences of accident sequences, expressed in terms of radiation dose to members of the public, and inputs to accident analysis, e.g., decay heat in fuel following a loss-of-coolant accident, are also calculated. Another role of the analyses is to demonstrate that the design of the plant satisfies the principle of ALARA (as low as reasonably achievable) radiation doses. This principle is applied throughout the design process to minimize worker and public doses. The principle of ALARA is an inherent part of all design-assist recommendations and safety and licensing assessments. The main focus of an ALARA exercise at the design stage is to minimize the radiation hazards at the source. This exploits material selection and impurity specifications and relies

  20. Applying Physically Representative Watershed Modelling to Assess Peak and Low Flow Response to Timber Harvest: Application for Watershed Assessments

    Science.gov (United States)

    MacDonald, R. J.; Anderson, A.; Silins, U.; Craig, J. R.

    2014-12-01

    Forest harvesting, insects, disease, wildfire, and other disturbances can combine with climate change to cause unknown changes to the amount and timing of streamflow from critical forested watersheds. Southern Alberta forest and alpine areas provide downstream water supply for agriculture and water utilities that supply approximately two thirds of the Alberta population. This project uses datasets from intensely monitored study watersheds and hydrological model platforms to extend our understanding of how disturbances and climate change may impact various aspects of the streamflow regime that are of importance to downstream users. The objectives are 1) to use the model output of watershed response to disturbances to inform assessments of forested watersheds in the region, and 2) to investigate the use of a new flexible modelling platform as a tool for detailed watershed assessments and hypothesis testing. Here we applied the RAVEN hydrological modelling framework to quantify changes in key hydrological processes driving peak and low flows in a headwater catchment along the eastern slopes of the Canadian Rocky Mountains. The model was applied to simulate the period from 2006 to 2011 using data from the Star Creek watershed in southwestern Alberta. The representation of relevant hydrological processes was verified using snow survey, meteorological, and vegetation data collected through the Southern Rockies Watershed Project. Timber harvest scenarios were developed to estimate the effects of cut levels ranging from 20 to 100% over a range of elevations, slopes, and aspects. We quantified changes in the timing and magnitude of low flow and high flow events during the 2006 to 2011 period. Future work will assess changes in the probability of low and high flow events using a long-term meteorological record. This modelling framework enables relevant processes at the watershed scale to be accounted in a physically robust and computational efficient manner. Hydrologic

    International Nuclear Information System (INIS)

    Occupational exposures of radiation workers due to external sources of radiations in three major categories of work i. e., Pakistan Research Reactors (PRR), Isotope Production Plant (IPP) and Applied Health Physics (AHP) were measured using thermoluminescent dosimeters and reported in this article for the period 2003 to 2007. It has been found that average annual effective doses remained in the range of 1.52-3.36 mSv, 0.91-3.19 mSv, and 0.24-2.63 mSv at PRR, IPP, and AHP, respectively, during the said period. All doses are well below the annual dose limit of 20 mSv and found to be comparable with the doses received by the workers in other parts of the world. No over exposure case has been identified during the period. It can be concluded that radiation workers of PINSTECH are well trained and observe the principles of radiation protection. Doses are analogous with UNSCEAR report and other countries of the world, in the same fields. (author)

    2010-01-01

    Los Alamos National Laboratory will review its Computational Physics and Applied Mathematics (CPAM) capabilities in 2010. The goals of capability reviews are to assess the quality of science, technology, and engineering (STE) performed by the capability, evaluate the integration of this capability across the Laboratory and within the scientific community, examine the relevance of this capability to the Laboratory's programs, and provide advice on the current and future directions of this capability. This is the first such review for CPAM, which has a long and unique history at the laboratory, starting from the inception of the Laboratory in 1943. The CPAM capability covers an extremely broad technical area at Los Alamos, encompassing a wide array of disciplines, research topics, and organizations. A vast array of technical disciplines and activities are included in this capability, from general numerical modeling, to coupled mUlti-physics simulations, to detailed domain science activities in mathematics, methods, and algorithms. The CPAM capability involves over 12 different technical divisions and a majority of our programmatic and scientific activities. To make this large scope tractable, the CPAM capability is broken into the following six technical 'themes.' These themes represent technical slices through the CP AM capability and collect critical core competencies of the Laboratory, each of which contributes to the capability (and each of which is divided into multiple additional elements in the detailed descriptions of the themes in subsequent sections): (1) Computational Fluid Dynamics - This theme speaks to the vast array of scientific capabilities for the simulation of fluids under shocks, low-speed flow, and turbulent conditions - which are key, historical, and fundamental strengths of the laboratory; (2) Partial Differential Equations - The technical scope of this theme is the applied mathematics and numerical solution of partial

We contribute to improving the theory by testing extensions such as the model of goal-directed behaviour (MGDB, which adds desire and anticipated positive and negative emotions) applied to physical activity (PA) intention. We also test the inclusion of a descriptive norm construct as an addition to the subjective norms construct, also applied to PA, resulting in two additio...

    There have been three physics meetings since the last CMS week: “physics days” on March 27-29, the Physics/ Trigger week on April 23-27 and the most recent physics days on May 22-24. The main purpose of the March physics days was to finalize the list of “2007 analyses”, i.e. the few topics that the physics groups will concentrate on for the rest of this calendar year. The idea is to carry out a full physics exercise, with CMSSW, for select physics channels which test key features of the physics objects, or represent potential “day 1” physics topics that need to be addressed in advance. The list of these analyses was indeed completed and presented in the plenary meetings. As always, a significant amount of time was also spent in reviewing the status of the physics objects (reconstruction) as well as their usage in the High-Level Trigger (HLT). The major event of the past three months was the first “Physics/Trigger week” in Apri...

  8. The Design Process of Physical Security as Applied to a U.S. Border Port of Entry

    Wagner, G.G.

    1999-02-22

    This paper details the application of a standard physical security system design process to a US Border Port of Entry (PoE) for vehicle entry/exit. The physical security design methodology is described as well as the physical security similarities to facilities currently at a US Border PoE for vehicles. The physical security design process description includes the various elements that make up the methodologies well as the considerations that must be taken into account when dealing with system integration of those elements. The distinctions between preventing unlawful entry/exit of illegal contraband and personnel are described. The potential to enhance the functions of drug/contraband detection in the Pre-Primary Inspection area through the application of emerging technologies are also addressed.

  9. Study of applied magnetic field magnetoplasmadynamic thrusters with particle-in-cell code with Monte Carlo collision. I. Computation methods and physical processes

    International Nuclear Information System (INIS)

    A two-dimensional axisymmetric electromagnetic particle-in-cell code with Monte Carlo collision conditions has been developed for an applied-field magnetoplasmadynamic thruster simulation. This theoretical approach establishes a particle acceleration model to investigate the microscopic and macroscopic characteristics of particles. This new simulation code was used to study the physical processes associated with applied magnetic fields. In this paper (I), detail of the computation procedure and results of predictions of local plasma and field properties are presented. The numerical model was applied to the configuration of a NASA Lewis Research Center 100-kW magnetoplasmadynamic thruster which has well documented experimental results. The applied magnetic field strength was varied from 0 to 0.12 T, and the effects on thrust were calculated as a basis for verification of the theoretical approach. With this confirmation, the changes in the distributions of ion density, velocity, and temperature throughout the acceleration region related to the applied magnetic fields were investigated. Using these results, the effects of applied field on physical processes in the thruster discharge region could be represented in detail, and those results are reported.

    A remarkable amount of progress has been made in Physics since the last CMS Week in June given the exponential growth in the delivered LHC luminosity. The first major milestone was the delivery of a variety of results to the ICHEP international conference held in Paris this July. For this conference, CMS prepared 15 Physics Analysis Summaries on physics objects and 22 Summaries on new and interesting physics measurements that exploited the luminosity recorded by the CMS detector. The challenge was incorporating the largest batch of luminosity that was delivered only days before the conference (300 nb-1 total). The physics covered from this initial running period spanned hadron production measurements, jet production and properties, electroweak vector boson production, and even glimpses of the top quark. Since then, the accumulated integrated luminosity has increased by a factor of more than 100, and all groups have been working tremendously hard on analysing this dataset. The September Physics Week was held ...

    The CPT project came to an end in December 2006 and its original scope is now shared among three new areas, namely Computing, Offline and Physics. In the physics area the basic change with respect to the previous system (where the PRS groups were charged with detector and physics object reconstruction and physics analysis) was the split of the detector PRS groups (the old ECAL-egamma, HCAL-jetMET, Tracker-btau and Muons) into two groups each: a Detector Performance Group (DPG) and a Physics Object Group. The DPGs are now led by the Commissioning and Run Coordinator deputy (Darin Acosta) and will appear in the correspond¬ing column in CMS bulletins. On the physics side, the physics object groups are charged with the reconstruction of physics objects, the tuning of the simulation (in collaboration with the DPGs) to reproduce the data, the provision of code for the High-Level Trigger, the optimization of the algorithms involved for the different physics analyses (in collaboration with the analysis gr...

  17. Non-extensive statistical physics applied to heat flow and the earthquake frequency-magnitude distribution in Greece

    2016-08-01

    This study investigates seismicity in Greece and its relation to heat flow, based on the science of complex systems. Greece is characterised by a complex tectonic setting, which is represented mainly by active subduction, lithospheric extension and volcanism. The non-extensive statistical physics formalism is a generalisation of Boltzmann-Gibbs statistical physics and has been successfully used for the analysis of a variety of complex systems, where fractality and long-range interactions are important. Consequently, in this study, the frequency-magnitude distribution analysis was performed in a non-extensive statistical physics context, and the non-extensive parameter, qM, which is related to the frequency-magnitude distribution, was used as an index of the physical state of the studied area. Examination of the spatial distribution of qM revealed its relation to the spatial distribution of seismicity during the period 1976-2009. For focal depths ≤40 km, we observe that strong earthquakes coincide with high qM values. In addition, heat flow anomalies in Greece are known to be strongly related to crustal thickness; a thin crust and significant heat flow anomalies characterise the central Aegean region. Moreover, the data studied indicate that high heat flow is consistent with the absence of strong events and consequently with low qM values (high b-values) in the central Aegean region and around the volcanic arc. However, the eastern part of the volcanic arc exhibits strong earthquakes and high qM values whereas low qM values are found along the North Aegean Trough and southwest of Crete, despite the fact that strong events are present during the period 1976-2009 in both areas.

    Full Text Available Introduction & Objective: Sedentary women are at risk for problems such as obesity, diabetes, depression and cardiovascular disease. Meanwhile, due to long working hours and excessive travel time from home to work and vice versa the employees have minimal physical activity .The purpose of this study was to investigate the effective psychometric factors on physical activity of female employees, according to the Trans-theoretical Model and theory of planned behavior. Materials & Methods: In this cross-sectional study, 95 female staff of Tehran University was selected through a call. In order to collect data, a questionnaire with acceptable, reliability and validity, including demographic data, and constructs of planned behavior theory as well as Trans-theoretical Model was used. The data was analyzed using SPSS version 21 statisti-cal tests; correlation and stepwise regression were also performed. Results: In this study, 72% of the population was in the inactive stages (pre-contemplation, contemplation and preparation and only 28% of patients had regular physical activity. There was a significant positive correlation between the behavioral intention and attitude scores (P = 0.02, perceived behavioral control (P = 0.000, self-efficacy (P = 0.000 and stage of change (P = 0.000, but subjective norms score (P = 0.605 was irrelevant. Conclusion: The results of this study showed that self-efficacy and perceived behavioral con-trol can affect female employees’ intention and physical activity behaviors. So, the authori-ties should seriously consider these factors in educational planning for this stratum of society, remove barriers for the participation of more employees in sporting activities, and offer fa-cilitators at the community level.

  20. A study of applying conceptual change research to the secondary physics classroom in the area of mechanics

    Sutherland, Erin Combs

    Recent research in science education has reached the consensus that in coming to understand science, students' learning must be viewed as a process of conceptual change. Much research has been done to determine what misconceptions are held by students. There has also been some effort to develop isolated lesson plans to assist teachers in altering student misconceptions. However, despite these efforts, research on alternative conceptions has still not made its way into the classroom. This study is an attempt to introduce conceptual change teaching techniques to experienced high school physics teachers in such a way that corresponds with their normal curriculum, All of the physics classes in one school system participated in the study. Two of the four teachers (N = 37) followed conceptual change lesson plans developed by the researcher and two teachers (N = 38) taught using their normal curriculum. The success of the lesson plans in implementing conceptual change in the students was determined by pre- and posttests as well as pre- and postinterviews. The teachers were also interviewed about the success of the unit. Overall, the students showed progress in their test performance, although there was no statistically significant difference between the two groups. Speculations and recommendations about the use of conceptual change teaching techniques with secondary physics students conclude this investigation.

    2015-12-01

    Full Text Available Purpose. The contradictions in the use of the term «reactive power» require justification by clarifying its physical meaning. The aim of the paper is to reveal the physical meaning of the term «reactive power» applied to three-phase three-wire and four-wire energy supply systems. Methodology. We have applied the modern theory of instantaneous active and reactive power, the graphical filling complex branched energy supply system of simplified design scheme, the theory of electrical circuits, computer Matlab-simulation. Results. We have provided answers to six basic questions that reveal the physical meaning and definition of the concept of «reactive power». We have justified the assumptions suggesting a universal calculation formula to determine the relative total power loss in the three-phase energy supply system as the sum of four components caused by: a minimal losses, reactive power, active power pulsations and instantaneous current flow in the neutral wire. Originality. We have developed the definition that reveals the physical meaning of the term «reactive power» for three-phase energy supply systems corresponding to modern theories of instantaneous active and reactive power. Practical value. We have proposed energy efficiency method ideas of energy supply systems with non-linear load based on the additional components of the power losses calculation. The further development of the method will allow to amend the design, selection and operation of the power active filters practices.

    Health Locus of Control (HLC) classifies our beliefs about the connection between our actions and health outcomes (Skinner, 1996) into three categories: "internal control", corresponding to health being the result of an individual's effort and habits; "control by powerful others", whereby health depends on others, such as doctors; and "chance control", according to which health depends on fate and chance. Using Choice Experiments we investigate the relationship between HLC and willingness to change lifestyle, in terms of eating habits, physical activity and associated cardiovascular disease risk, in a 384 person sample representative of the 40-65 aged population of Northern Ireland administered between February and July 2011. Using latent class analysis we identify three discrete classes of people based on their HLC: the first class is sceptical about their capacity to control their health and certain unhealthy habits. Despite being unsatisfied with their situation, they are reluctant to accept behaviour changes. The second is a group of individuals unhappy with their current situation but willing to change through exercise and diet. Finally, a group of healthy optimists is identified, who are satisfied with their current situation but happy to take more physical activity and improve their diet. Our findings show that any policy designed to modify people's health related behaviour should consider the needs of this sceptical class which represents a considerable proportion of the population in the region.

    The allocation of a significant amount of new funding for health promotion in Australia through the National Partnership Agreement on Preventive Health (2009-14) created a unique opportunity to implement a comprehensive approach to the prevention of chronic diseases and demonstrate significant health improvements. Building on existing health promotion infrastructure in Local Health Districts, the NSW Ministry of Health adopted a scaled-up state-wide capacity-building model, designed to alter policies and practices in key children's settings to increase healthy eating and physical activity among children. NSW also introduced a performance monitoring framework to track implementation and impacts. This paper describes the model that NSW developed for monitoring state-wide programs in the Children's Healthy Eating and Physical Activity Program and presents the model's application to early childhood education and care and primary school settings, including current results. This approach to monitoring the scaling up of program implementation at the state-wide level has potential for more widespread application in other policy areas in NSW. PMID:25828447

    The initial MOATA safety assessment was based on data and calculations available before the advent of multigroup diffusion theory codes in two dimensions. That assessment is being revised and extended to gain approval for 100 kW operation. The more detailed representation obtained in the new calculations has resulted in a much better understanding of the physics of this reactor. The properties of the reactor are determined to a large extent by neutron leakage from the rather thin core tanks. In particular the effect of leakage on the coupling between the core tanks and on reactivity coefficients has been clarified and quantified. In neutron data studies, the theoretical fission product library was revised, checked against any experimental values and distributed to interested overseas centres. Some further nubar work was done vith much better neutron energy resolution, and confirmed our earlier measurements. A promising formulation of R matrix theory of nuclear interaction is expected to lead to simpler multilevel resonance parameter description. With large amounts of digital data being collected, dissplayed and used by theoreticians and experimentalists, more attention -was given to visual interactive computer displays. This interest is generating constructive proposals for use of the dataway now being installed between the Division and the IBM 360/50 computer. The study of gamma rays following the capture of keV neutrons continues to reveal new and interesting features of the physical processes involved. A detailed international compilation of the gamma rays emitted and their intensities is in progress. The work on nickel-68, amongst others, has enabled a partial capture cross section to be generated from the gamma ray parameters obtained by experiment. Much work still remains to be done, possibly at other establishments with more extensive facilities.

    Since the last CMS Week, all physics groups have been extremely active on analyses based on the full 2010 dataset, with most aiming for a preliminary measurement in time for the winter conferences. Nearly 50 analyses were approved in a “marathon” of approval meetings during the first two weeks of March, and the total number of approved analyses reached 90. The diversity of topics is very broad, including precision QCD, Top, and electroweak measurements, the first observation of single Top production at the LHC, the first limits on Higgs production at the LHC including the di-tau final state, and comprehensive searches for new physics in a wide range of topologies (so far all with null results unfortunately). Most of the results are based on the full 2010 pp data sample, which corresponds to 36 pb-1 at √s = 7 TeV. This report can only give a few of the highlights of a very rich physics program, which is listed below by physics group...

  18. BOOK REVIEW: The Quantum Mechanics Solver: How to Apply Quantum Theory to Modern Physics, 2nd edition

    Science.gov (United States)

    Robbin, J. M.

    2007-07-01

    he hallmark of a good book of problems is that it allows you to become acquainted with an unfamiliar topic quickly and efficiently. The Quantum Mechanics Solver fits this description admirably. The book contains 27 problems based mainly on recent experimental developments, including neutrino oscillations, tests of Bell's inequality, Bose Einstein condensates, and laser cooling and trapping of atoms, to name a few. Unlike many collections, in which problems are designed around a particular mathematical method, here each problem is devoted to a small group of phenomena or experiments. Most problems contain experimental data from the literature, and readers are asked to estimate parameters from the data, or compare theory to experiment, or both. Standard techniques (e.g., degenerate perturbation theory, addition of angular momentum, asymptotics of special functions) are introduced only as they are needed. The style is closer to a non-specialist seminar rather than an undergraduate lecture. The physical models are kept simple; the emphasis is on cultivating conceptual and qualitative understanding (although in many of the problems, the simple models fit the data quite well). Some less familiar theoretical techniques are introduced, e.g. a variational method for lower (not upper) bounds on ground-state energies for many-body systems with two-body interactions, which is then used to derive a surprisingly accurate relation between baryon and meson masses. The exposition is succinct but clear; the solutions can be read as worked examples if you don't want to do the problems yourself. Many problems have additional discussion on limitations and extensions of the theory, or further applications outside physics (e.g., the accuracy of GPS positioning in connection with atomic clocks; proton and ion tumor therapies in connection with the Bethe Bloch formula for charged particles in solids). The problems use mainly non-relativistic quantum mechanics and are organised into three

  19. Applying physical input-output tables of energy to estimate the energy ecological footprint (EEF) of Galicia (NW Spain)

    International Nuclear Information System (INIS)

    Nowadays, the achievement of sustainable development constitutes an important constraint in the design of energy policies, being necessary the development of reliable indicators to obtain helpful information about the use of energy resources. The ecological footprint (EF) provides a referential framework for the analysis of human demand for bioproductivity, including energy issues. In this article, the theoretical bases of the footprint analysis are described by applying input-output tables of energy to estimate the Galician energy ecological footprint (EEF). It is concluded that the location of highly polluting industries in Galicia makes the Galician EEF quite higher than more developed regions of Spain. The relevance of the outer component of the Galician EEF is also studied. First, available information seems to indicate that the energy incorporated to the trading of manufactured goods would notably increase the Galician consumption of energy. On the other hand, the inclusion of electricity trade in the EEF analysis, including an adjustment, following the same philosophy as with manufactured goods is proposed. This adjustment would substantially reduce the Galician EEF, as the exported electricity widely exceeds the imported one

We draw attention to the great diversity of problems, both in accelerator experiments (for example, the study of the coherence of synchrotron radiation) and in other, sometimes quite unrelated fields, such as metrology, high-temperature superconductivity, biology, medicine etc., which might be solved by means of infrared synchrotron diagnostics, covering the interval of wavelengths 0.3 - 40 μm, which is much larger than the spectral range that is widely used at present (basically, the range 0.3 - 1.1 μm) in various experiments and investigations. The extension of the spectral range of positively diagnosed synchrotron radiation opens up new possibilities and prospects for solving scientific and applied problems

  3. Non extensive statistical physics applied in fracture-induced electric signals during triaxial deformation of Carrara marble

    2014-05-01

    We have conducted room-temperature, triaxial compression experiments on samples of Carrara marble, recording concurrently acoustic and electric current signals emitted during the deformation process as well as mechanical loading information and ultrasonic wave velocities. Our results reveal that in a dry non-piezoelectric rock under simulated crustal pressure conditions, a measurable electric current (nA) is generated within the stressed sample. The current is detected only in the region beyond (quasi-)linear elastic deformation; i.e. in the region of permanent deformation beyond the yield point of the material and in the presence of microcracking. Our results extend to shallow crustal conditions previous observations of electric current signals in quartz-free rocks undergoing uniaxial deformation and support the idea of a universal electrification mechanism related to deformation. Confining pressure conditions of our slow strain rate (10-6 s-1) experiments range from the purely brittle regime (10 MPa) to the semi-brittle transition (30-100MPa) where cataclastic flow is the dominant deformation mechanism. Electric current is generated under all confining pressures,implying the existence of a current-producing mechanism during both microfracture and frictional sliding. Some differences are seen in the current evolution between these two regimes, possibly related to crack localisation. In all cases, the measured electric current exhibits episodes of strong fluctuations over short timescales; calm periods punctuated by bursts of strong activity. For the analysis, we adopt an entropy-based statistical physics approach (Tsallis, 1988), particularly suited to the study of fracture related phenomena. We find that the probability distribution of normalised electric current fluctuations over short time intervals (0.5 s) can be well described by a q-Gaussian distribution of a form similar to that which describes turbulent flows. This approach yields different entropic

  4. A gridded hourly rainfall dataset for the UK applied to a national physically-based modelling system

    An hourly gridded rainfall product has great potential for use in many hydrological applications that require high temporal resolution meteorological data. One important example of this is flood risk management, with flooding in the UK highly dependent on sub-daily rainfall intensities amongst other factors. Knowledge of sub-daily rainfall intensities is therefore critical to designing hydraulic structures or flood defences to appropriate levels of service. Sub-daily rainfall rates are also essential inputs for flood forecasting, allowing for estimates of peak flows and stage for flood warning and response. In addition, an hourly gridded rainfall dataset has significant potential for practical applications such as better representation of extremes and pluvial flash flooding, validation of high resolution climate models and improving the representation of sub-daily rainfall in weather generators. A new 1km gridded hourly rainfall dataset for the UK has been created by disaggregating the daily Gridded Estimates of Areal Rainfall (CEH-GEAR) dataset using comprehensively quality-controlled hourly rain gauge data from over 1300 observation stations across the country. Quality control measures include identification of frequent tips, daily accumulations and dry spells, comparison of daily totals against the CEH-GEAR daily dataset, and nearest neighbour checks. The quality control procedure was validated against historic extreme rainfall events and the UKCP09 5km daily rainfall dataset. General use of the dataset has been demonstrated by testing the sensitivity of a physically-based hydrological modelling system for Great Britain to the distribution and rates of rainfall and potential evapotranspiration. Of the sensitivity tests undertaken, the largest improvements in model performance were seen when an hourly gridded rainfall dataset was combined with potential evapotranspiration disaggregated to hourly intervals, with 61% of catchments showing an increase in NSE between

      The period since the last CMS Bulletin has been historic for CMS Physics. The pinnacle of our physics programme was an observation of a new particle – a strong candidate for a Higgs boson – which has captured worldwide interest and made a profound impact on the very field of particle physics. At the time of the discovery announcement on 4 July, 2012, prominent signals were observed in the high-resolution H→γγ and H→ZZ(4l) modes. Corroborating excess was observed in the H→W+W– mode as well. The fermionic channel analyses (H→bb, H→ττ), however, yielded less than the Standard Model (SM) expectation. Collectively, the five channels established the signal with a significance of five standard deviations. With the exception of the diphoton channel, these analyses have all been updated in the last months and several new channels have been added. With improved analyses and more than twice the i...

    The collisions last year at 900 GeV and 2.36 TeV provided the long anticipated collider data to the CMS physics groups. Quite a lot has been accomplished in a very short time. Although the delivered luminosity was small, CMS was able to publish its first physics paper (with several more in preparation), and commence the commissioning of physics objects for future analyses. Many new performance results have been approved in advance of this CMS Week. One remarkable outcome has been the amazing agreement between out-of-the-box data with simulation at these low energies so early in the commissioning of the experiment. All of this is testament to the hard work and preparation conducted beforehand by many people in CMS. These analyses could not have happened without the dedicated work of the full collaboration on building and commissioning the detector, computing, and software systems combined with the tireless work of many to collect, calibrate and understand the data and our detector.

    The Physics Groups are actively engaged on analyses of the first data from the LHC at 7 TeV, targeting many results for the ICHEP conference taking place in Paris this summer. The first large batch of physics approvals is scheduled for this CMS Week, to be followed by four more weeks of approvals and analysis updates leading to the start of the conference in July. Several high priority analysis areas were organized into task forces to ensure sufficient coverage from the relevant detector, object, and analysis groups in the preparation of these analyses. Already some results on charged particle correlations and multiplicities in 7 TeV minimum bias collisions have been approved. Only one small detail remains before ICHEP: further integrated luminosity delivered by the LHC! Beyond the Standard Model measurements that can be done with these data, the focus changes to the search for new physics at the TeV scale and for the Higgs boson in the period after ICHEP.

      2012 has started off as a very busy year for the CMS Physics Groups. Planning for the upcoming higher luminosity/higher energy (8 TeV) operation of the LHC and relatively early Rencontres de Moriond are the high-priority activities for the group at the moment. To be ready for the coming 8-TeV data, CMS has made a concerted effort to perform and publish analyses on the 5 fb−1 dataset recorded in 2011. This has resulted in the submission of 16 papers already, including nine on the search for the Higgs boson. In addition, a number of preliminary results on the 2011 dataset have been released to the public. The Exotica and SUSY groups approved several searches for new physics in January, such as searches for W′ and exotic highly ionising particles. These were highlighted at a CERN seminar given on 24th  January.

    Physics-wise, the CMS week in December was dominated by discussions of the analyses that will be carried out in the “next six months”, i.e. while waiting for the first LHC collisions.  As presented in December, analysis approvals based on Monte Carlo simulation were re-opened, with the caveat that for this work to be helpful to the goals of CMS, it should be carried out using the new software (CMSSW_2_X) and associated samples.  By the end of the week, the goal for the physics groups was set to be the porting of our physics commissioning methods and plans, as well as the early analyses (based an integrated luminosity in the range 10-100pb-1) into this new software. Since December, the large data samples from CMSSW_2_1 were completed. A big effort by the production group gave a significant number of events over the end-of-year break – but also gave out the first samples with the fast simulation. Meanwhile, as mentioned in December, the arrival of 2_2 meant that ...

    All the mechanical and electronic components for the zero power splitable machine (the critical facility) arrived in excellent condition from France. Installation began and good progress was made on the mechanical side where the base and tables were successfully assembled and are being adjusted to meet the exacting specification. Power transients arising from the insertion of short reactivity steps were studied for the reactors, HIFAR, MOATA and the critical facility. Some effort was also devoted to the study of blowdown accidents in light water reactors and calculations of some Italian experiments were made successfully. The measurements of fast fission factor and initial conversion ratios for a range of natural uranium heavy water reactors were completed, and good progress is being made with neutron streaming in aluminium-water lattices. Many other investigators of this problem appear to have neglected or given insufficient attention to the case where the neutron beam is parallel to the plates. It is difficult to fit a cosine curve uniquely as coarse and fine features can not be separated. Previous analysis of the moisture content of soils and concrete by neutron scattering was successfully applied to obtain information on the variation of the moisture in large coal stacks as a function of time. This work was done in conjunction with Electricity Commission of N.S.W. Although a small Pu/Be source was found adequate for the above work, development continued on producing neutron pulses by means of a coaxial plasma focus device. Neutron pulses were produced regularly, but the output was variable; the fault was traced to breakdowns at the breech end of the device where restriking occurs. Although discrepancies of about 2% exist between V-bar for spontaneous fission of 252Cf as measured by the liquid scintillation method and by the Manganese bath method, this important quantity is being measured locally using the liquid scintillator method.

    The study of quick clay landslides in Nordic countries, such as Sweden and Norway, is wide and varied. However, the occurrence of catastrophes like those in Munkedal, Sweden, in 2006, demands a more complete characterization of these materials and their extensiveness. The objectives of this research are mainly focused on obtaining information about the properties and behavior of quick clays in an area prone to landslides in southwestern Sweden. Two fieldwork campaigns were carried out in 2011 and 2013, using methods such as 2D and 3D P-wave and S-wave seismic, geoelectrics, controlled-source and radio-magnetotellurics, ground gravity, as well as downhole geophysics (measuring fluid temperature and conductivity, gamma radiation, sonic velocity and resistivity) performed in three boreholes located in the study area. Drill cores recovered using the SONIC technique provided samples for paleontological information, as well as laboratory measurements of physical properties of the subsurface materials to a maximum subsurface depth of about 60 m. The laboratory measurements included grain size analysis, mineral magnetic properties, electric conductivity, pH, salinity, total dissolved solids, x-ray fluorescence (XRF), and a reconnaissance study of the fossil content. A correlation study of the downhole geophysical measurements, 2D seismic sections located at the intersection with the boreholes and the sample observations indicated that the presence of quick clays is associated with contacts with coarse-grained materials. Although the PVC casing of the boreholes interferes with the sonic and resistivity measurements, the perforated parts of the PVC casing show significant changes. The most important variations in magnetic susceptibility and conductivity mostly coincide with these coarse-grained layers, supporting the seismic data. Coarse-grained layers are characterized by enhanced magnetic susceptibility and conductivity. Grain size analysis results on subsamples from the

We had more than 40 presentations at the Workshop, which was an important milestone for 2007 physics analyses in the EWK and TOP areas. The Standard Model has been tested empirically by many previous experiments. Observables which are nowadays known with high precision will play a major role for data-based CMS calibrations. A typical example is the use of the Z to monitor electron and muon reconstruction in di-lepton inclusive samples. Another example is the use of the W mass as a constraint for di-jets in the kinematic fitting of top-quark events, providing information on the jet energy scale. The predictions of the Standard Model, for what concerns proton collisions at the LHC, are accurate to a level that the production of W/Z and top-quark events can be used as a powerful tool to commission our experiment.

    The theory of planned behavior (TPB) has received its fair share of criticism lately, including calls for it to retire. We contribute to improving the theory by testing extensions such as the model of goal-directed behavior (MGDB, which adds desire and anticipated positive and negative emotions) applied to physical activity (PA) intention. We also test the inclusion of a descriptive norms construct as an addition to the subjective norms construct, also applied to PA, resulting in two additional models: TPB including descriptive norms (TPB + DN) and MGDB including descriptive norms (MGDB + DN). The study is based on an online survey of 400 young adult Internet users, previously enrolled in a subject pool. Confirmatory factor analysis (CFA) showed that TPB and TPB + DN were not fit for purpose, while MGDB and MGDB + DN were. Structural equation modelling (SEM) conducted on MGDB and MGDB + DN showed that the inclusion of descriptive norms took over the significance of injunctive norms, and increased the model's account of total variance in intention to be physically active.

Di-lepton workshop Most analysis groups use a di-lepton trigger or a combination of single and di-lepton triggers in 2011.

    Quality management on dairy farms becomes more and more important regarding the different areas of animal health, animal welfare and food safety. Monitoring animals, farm conditions and farm records can be extended with risk identification and risk management. The hazard analysis critical control point's system is useful as an on farm strategy to control the product as well as the production process on the areas of animal health, animal welfare and food safety. This article deals in detail with the question how to develop a qualitative method where risk can be defined as an interaction between probability and impact. Two parts of the production process (milk harvest and treatment of cows) where used as an example how to apply the hazard analysis critical control point's system on chemical, physical and microbiological contaminants of milk. Not just only by summarizing the different critical checkpoints for each area but also by giving them a precise judgement of probability and impact. PMID:15835281

    In this diploma thesis we study the characteristics of electromagnetic fields carrying orbital angular momentum (OAM) by analyzing and utilizing results achieved in optics and then apply them to the radio domain to enable innovative radio studies of space and the development of new concepts in wireless communications. With the recent advent of fast digital converters it has become possible, over a wide radio frequency range, to manipulate not only the modulation properties of any given signal carried by a radio beam, but also the physical field vectors which make up the radio beam itself. Drawing inferences from results obtained in optics and quantum communication research during the past 10-15 years, we extract the core information about fields carrying orbital angular momentum. We show that with this information it is possible to design an array of antennas which, together with digital receivers/transmitters, can readily produce, under full software control, a radio beam that carries electromagnetic orbital...

    Different optical parameters for thin solid films can be computed as functions of wavelength from the optical transmission and reflection spectra. Subsequently, several models can be tested on the obtained data, in order to check their validity with respect to the materials under study. Moreover, these models offer the possibility to estimate essential physical parameters. Such models are tested within this article for the refraction index and for the real part of the complex dielectric constant, for bismuth trioxide thin films deposited on glass substrates maintained at three different temperatures. Also, the model proposed by Tauc is applied for the absorption spectrum of the same films, in order to determine the type of electronic transition and to estimate the optical energy bandgap. It will be noticed that the optical parameters vary rather significantly with changing substrate temperature, while the structure of the films, as studied by means of X-ray diffractometry is almost insensitive to this change of deposition parameter.

    This study summarizes the evidence from quantitative systematic reviews that assessed the association between urban environment attributes and physical activity. It also documents sociopolitical barriers and facilitators involved in urban interventions linked with active living in the ten most populated urban settings of Latin America. The synthesis of evidence indicates that several attributes of urban environments are associated with physical activity, including land-use mix and cycling infrastructure. The documentary analysis indicated that despite the benefits and opportunities provided by the programs and existing infrastructure in the examined cities, an overall concern is the rising inequality in the coverage and distribution of the initiatives in the region. If these programs and initiatives are to achieve a real population level effect that helps to reduce health disparities, they need to examine their social and spatial distribution within the cities so they can reach underserved populations and develop to their full potential.

    The purpose of this work is to develop and try out tests having a tree structure aimed at assessing the applicability of different techniques to the remediation of polluted soils. One of the case studies is a soil from an old mining area, heavily polluted by arsenic (As content >3%). The first step in this case study was to determine the arsenic speciation in a sample of the soil so as to determine its potential for treatment. To this purpose, the soil was characterised both physically (through soil fractionation and physical analysis of its constituents) and chemically (through chemical attacks). The results of the physical characterisation show a large variety of arsenic-bearing phases, such as sulphides from the mining activities, slag from the pyrometallurgical processing and, above all, Fe-As oxide phases encrustations on the grains, probably resulting from weathering and oxidation of the sulphides. The encrustations are the main arsenic-carriers in the soil; iron arsenates (like scorodite type) have been identified, but they are generally iron hydroxides on which the arsenic is sorbed or coprecipitated. The development of a test consisting in successive chemical attacks at high and low pH, thus respectively favouring arsenates desorption or iron hydroxides dissolution, has enabled us to demonstrate tht the main mechanism linking the arsenic and the solid is their sorption on the iron hydroxides. An exchange test with phosphates, carried out at neutral pH, supports these observations by releasing 6% of arsenic soil content, and confirms the strong potential risk presented by this soil, even in the absence of physical, chemical modifications or redox conditions.

    Full Text Available Ergonomic assessment of a workplace requires the evaluation of physical as well as cognitive aspects of a particular working situation. In particular the latter is hardly possible without interfering in the natural setting. Mobile acquisition of neurophysiological measures (such as parameters of the EEG may close this gap. At a simulated workplace we tracked older and younger participants with mobile EEG during a 4-5 hours work shift. They had to perform either a monotonous cognitive task, a self-paced cognitive task or a self-paced physical task in a predefined order. Self assessment, behavioral performance and spectral measures of the EEG (before most alpha power indicated that younger participants suffered from monotony. Older adults, on the other hand, were overall impaired by inefficient information processing. This was visible in EEG variations time-locked to eye blinks (blink-related synchronizations, a new measure to investigate cognitive processing in real life environments. Thus, we were able to distinguish between active and passive task-related aspects of mental fatigue without impinging on the natural working situation.

The detected results of the bikers who joined the study is by order, average age 14,50+0,58 years, height 170,75+2.99 cm and weight pretest 60,25+6,85 kg, final test 58,25+6,18 kg. As pre and post-tests, from the physical measurements, circumference and body fat, lactate and strength 1RM tests were carried out. Training program carried out 6 weeks. At the statistic analysis of the data that was obtained, descriptive statistics were made. Pre and post-tests of body fat, circumference, lactate and strength 1RM minimum, maximum and average rates were detected. Between their pre and post-tests, some quantitative differences can be seen. As a result, within the 6 weeks training program practiced upon the mountain bikers, strenght, climbing and interval trainings seem to effect their performances positively and the training program can be thought as an example model to those sports scientists who will prepare a study in this field.

  19. Diode laser (808 nm) applied to oral soft tissue lesions: a retrospective study to assess histopathological diagnosis and evaluate physical damage.

    2012-03-01

    The diode laser is today widely used in oral pathology to excise lesions; however, some controversy surrounds laser surgery, specifically the accuracy of pathological diagnosis and the control over thermal tissue damage. This study aimed to establish if physical damage induced by the diode laser could affect the histopathological diagnosis and to evaluate the damage caused to the resection margins. Between 2005 and 2010, at S. Gerardo Hospital, Milan, 608 cases of soft tissue lesions localized in the oral cavity (cheek, gingiva, buccal mucosa, tongue, and lips) were examined. Specimens were excised with an 808-nm diode laser, output 1.6-2.7 W, in continuous-wave mode with fibers of 320 μm. Specimens were fixed in 10% buffered formalin solution and examined separately under an optical microscope by two pathologists. In all of the specimens, changes to the epithelium, connective tissue and blood vessels, shape of incision damage, and overall width of modified tissues were evaluated. The data for specimens larger than 3 mm excised with the diode laser were not significant in terms of stromal changes or vascular stasis, while epithelial and stromal changes were significantly more frequent in specimens with a mean size below 3 mm; the diagnosis was not achievable in 46.15%. Our data show that the diode laser is a valid therapeutic instrument for excising oral lesions larger than 3 mm in diameter, but induces serious thermal effects in small lesions (mean size below 3 mm). However, from a clinical standpoint, it is suggested necessary that the specimens taken have in vivo a diameter of at least 5 mm in order to have a reliable reading of the histological sample.

    Full Text Available Engaging students to teach new concepts and to have students achieve individualized learning with the successful integration of those new concepts with their existing knowledge has been and remains the primary goal of college education. In this study drawing on information gathered over the past 2 plus decades, my findings have led me to develop two new separate ascending teaching-structures that are significantly helping me with content delivery, and simultaneously helping my students achieve greater success in mastering the material of my Physics 106 (Physics II, Electricity, Magnetism and Light classes. These two teachingstructures, called Contextualization Teaching and Rich Contextualization Teaching (RCT, with each structure relying on various aspects of a modified Bloom's cognitive domain taxonomy and on my description of and when to use each structure, along with my introduction of "subject learning convergences," are described and illustrated here. Finally, of students with open-minds and mentally connected to the subject being taught, I make the suggestion that my two ascending teaching-structures can be used for teaching such students new-concepts in any academic course where engaging students to teach new concepts represents the primary focus.

    Developmental dysplasia of the hip (DDH) has a broad spectrum of presentation with the minor findings resolving spontaneously and the most severe ones resulting in disability, if not diagnosed early in life. Diagnosis in the first few months of life allows conservative treatment with complete resolution in most cases. Suspicion of DDH is based on ethnic, family, and pregnancy history, and on physical examination of the newborn. Imaging assists in the diagnosis and follows the treatment. Different modalities have their own advantages and disadvantages. This article deals with the description of the disease, risk factors, statistics, the physical examination as applied to real-time sonography, and imaging (plain radiography, arthrography, computed tomography, and magnetic resonance imaging).

  3. MO-G-BRE-05: Clinical Process Improvement and Billing in Radiation Oncology: A Case Study of Applying FMEA for CPT Code 77336 (continuing Medical Physics Consultation)

    International Nuclear Information System (INIS)

    Purpose: The improvement of quality in healthcare can be assessed by Failure Mode and Effects Analysis (FMEA). In radiation oncology, FMEA, as applied to the billing CPT code 77336, can improve both charge capture and, most importantly, quality of the performed services. Methods: We created an FMEA table for the process performed under CPT code 77336. For a given process step, each member of the assembled team (physicist, dosimetrist, and therapist) independently assigned numerical values for: probability of occurrence (O, 1–10), severity (S, 1–10), and probability of detection (D, 1–10) for every failure mode cause and effect combination. The risk priority number, RPN, was then calculated as a product of O, S and D from which an average RPN was calculated for each combination mentioned above. A fault tree diagram, with each process sorted into 6 categories, was created with linked RPN. For processes with high RPN recommended actions were assigned. 2 separate R and V systems (Lantis and EMR-based ARIA) were considered. Results: We identified 9 potential failure modes and corresponding 19 potential causes of these failure modes all resulting in unjustified 77336 charge and compromised quality of care. In Lantis, the range of RPN was 24.5–110.8, and of S values – 2–10. The highest ranking RPN of 110.8 came from the failure mode described as “end-of-treatment check not done before the completion of treatment”, and the highest S value of 10 (RPN=105) from “overrides not checked”. For the same failure modes, within ARIA electronic environment with its additional controls, RPN values were significantly lower (44.3 for end-of-treatment missing check and 20.0 for overrides not checked). Conclusion: Our work has shown that when charge capture was missed that also resulted in some services not being performed. Absence of such necessary services may result in sub-optimal quality of care rendered to patients

  4. Applied radiation physics: The use of x-rays for the structural characterization of aqueous emulsions and the development of new insect sterilization protocols

    Science.gov (United States)

    Brar, Ramaninder K.

    X-rays have great potential of applications in a wide variety of fields. This dissertation presents the use of x-rays for the structural characterization of aqueous emulsions and for insect sterilization. The stabilization of hydrophobic colloids, such as oil droplets, in water has attracted scientist for a variety of scientific, pharmaceutical and industrial applications. Several studies have been done to understand the stability of oil-in-water emulsions. The work of Pashley and his coworkers has demonstrated that the removal of dissolved gasses from water enhances the dispersion of hydrophobic oil in water and these surfactant-free emulsions do not lose their stability when the previously removed gasses are reintroduced. However, very little is known about the structure and stability of these emulsions over time or even to what extent they form. The formation of a stable emulsion in the complete absence of a surfactant could provide an alternative approach to a physiologically safe drug carrier. In this dissertation we demonstrate the formation of stabilized surfactant-free degassed emulsions of hydrocarbons - hexane, heptane and octane and silicone oil in ultra-pure water. The enhancement of dispersion of oil droplets by degassing was large for highly hydrophobic silicone oil. Turbidity measurements and small angle x-ray scattering results show that the uniformly dispersed oil droplets weakly aggregate over a period of several hours. Gentle perturbation re-generates the dispersion to nearly initial conditions. The control of insect species for the protection of crops, livestock, and prevention of disease, such as dengue fever and malaria, is a high priority in today's global economy. Sterile Insect Technique (SIT), a method of insect extermination without the use of pesticides, has proven very effective in eradicating certain dipteran insect populations. However, when standard sterilization methods developed for dipterans are applied to mosquito populations

    (physical injury, structural and functional damage on buildings, lifelines and land cover) and indirect (socio-economic impacts) consequences. The method allows estimating the possible damage caused by torrential and gravitational hazards by combining weighted indicators (age, state, land use, number of occupied floors, etc.) reflecting the exposure of elements at risk (land cover, buildings, and lifelines) to obtain different maps of total consequences. Besides, this method allows introducing temporality by modifying the weight and the combination of variables. For example, we can operate the distinction between day and night or between the off-season and the touristic season. Another benefit of this method is to permit the visualization of the vulnerability evolution producing diachronic maps. All these maps, combined with adequate hazards map, will contribute to a better assessment of vulnerability in the Queyras and must help the development of better land use and evacuation plans, and thus are important tools for local authorities. This study will be completed by an analysis of social and institutional vulnerability realized on the basis of interview with local councillors and risk perception survey led with the local populations and the tourists.

  6. Applied Stratigraphy

    Science.gov (United States)

    Lucas, Spencer G.

    Stratigraphy is a cornerstone of the Earth sciences. The study of layered rocks, especially their age determination and correlation, which are integral parts of stratigraphy, are key to fields as diverse as geoarchaeology and tectonics. In the Anglophile history of geology, in the early 1800s, the untutored English surveyor William Smith was the first practical stratigrapher, constructing a geological map of England based on his own applied stratigraphy. Smith has, thus, been seen as the first “industrial stratigrapher,” and practical applications of stratigraphy have since been essential to most of the extractive industries from mining to petroleum. Indeed, gasoline is in your automobile because of a tremendous use of applied stratigraphy in oil exploration, especially during the latter half of the twentieth century. Applied stratigraphy, thus, is a subject of broad interest to Earth scientists.

    A confocal micro-beam X ray fluorescence microscope was constructed. The system was assembled from commercially available components, namely a low power X ray tube source, polycapillary X ray optics, silicon drift detector, and a video camera coupled to an optical microscope. The hardware and the developed software can already handle spatial as well as volumetric confocal scans. The spectrometer is controlled by software developed in-house. The graphical user interface as well as the communication protocols between hardware components was created by using the National Instruments LabVIEW. The camera image calibration and scan area definition software were also based entirely on the LabVIEW code. Presently, the main area of application of the newly constructed spectrometer is 2-dimensional mapping of element distribution in environmental, biological and geological samples with micrometer spatial resolution. The spectrometer was applied to homogeneity testing of titanium layers. A Monte Carlo simulation based quantitative analysis computer code for confocal XRF microscopy was also developed and tested with the use of a layered sample. (author)

    Applied Dynamics is an important branch of engineering mechanics widely applied to mechanical and automotive engineering, aerospace and biomechanics as well as control engineering and mechatronics. The computational methods presented are based on common fundamentals. For this purpose analytical mechanics turns out to be very useful where D’Alembert’s principle in the Lagrangian formulation proves to be most efficient. The method of multibody systems, finite element systems and continuous systems are treated consistently. Thus, students get a much better understanding of dynamical phenomena, and engineers in design and development departments using computer codes may check the results more easily by choosing models of different complexity for vibration and stress analysis.

  19. Applying radiation

    International Nuclear Information System (INIS)

    The invention discloses a method and apparatus for applying radiation by producing X-rays of a selected spectrum and intensity and directing them to a desired location. Radiant energy is directed from a laser onto a target to produce such X-rays at the target, which is so positioned adjacent to the desired location as to emit the X-rays toward the desired location; or such X-rays are produced in a region away from the desired location, and are channeled to the desired location. The radiant energy directing means may be shaped (as with bends; adjustable, if desired) to circumvent any obstruction between the laser and the target. Similarly, the X-ray channeling means may be shaped (as with fixed or adjustable bends) to circumvent any obstruction between the region where the X-rays are produced and the desired location. For producing a radiograph in a living organism the X-rays are provided in a short pulse to avoid any blurring of the radiograph from movement of or in the organism. For altering tissue in a living organism the selected spectrum and intensity are such as to affect substantially the tissue in a preselected volume without injuring nearby tissue. Typically, the selected spectrum comprises the range of about 0.1 to 100 keV, and the intensity is selected to provide about 100 to 1000 rads at the desired location. The X-rays may be produced by stimulated emission thereof, typically in a single direction

    the activities already underway in Nuclear Physics and Engineering, and preserves the identities and focus of the various institutions involved. ADS related research and development is being pursued by IPEN (design calculation, development of an Alternative Concept for a Fast Energy Amplifier). Moreover, IPEN operates a small cyclotrons, CV-28. The IPEN CV-28 cyclotron is presently not operational, but suitable for R and D: it is a compact, isochronous, multi-particle radiation source where protons, deuterons, 3He++, and alpha particles can be accelerated with variable energies up to 24, 14, 36, and 28 MeV respectively. Finally, IPEN is also operating the Cyclone-30 from IBA which is dedicated to radioisotope production (201-Tl, 123-I, 67-Ga), an electron accelerator used in high social and economic impact projects (e.g., food irradiation), and a Van de Graaff capable to provide a 14 MeV neutron source. The Physics Institute of Sao Paulo University-IFUSP is implementing various R and D activities/projects, in areas such as nuclear reactions with heavy ions, nuclear structure, photo nuclear reactions, ion implantation, non destructive techniques using accelerators beams. These programs are centered on IFUSP facilities, i.e., a heavy ion electrostatic accelerator (PELLETRON), a linear accelerator (LINAC), and an electron accelerator (MICROTRON), as well as associated experimental facilities. The institute is also performing theoretical research on nuclear reactions of interest to ADS (spallation-cascade evaporation model). Given the outlined scenario, IPEN-IFUSP have identified the possibility to launch a program on the utilization of accelerators. This programs would have three main pillars: R and D in basic and applied nuclear physics and engineering (e.g., low energy cross sections nuclear reactions, charged particle activation analysis, hydrogen implantation for angular correlation studies, excitation function determination, helium embrittlement in structural

    1991-01-01

    The book guides the reader from the foundations of statisti- cal thermodynamics including the theory of intermolecular forces to modern computer-aided applications in chemical en- gineering and physical chemistry. The approach is new. The foundations of quantum and statistical mechanics are presen- ted in a simple way and their applications to the prediction of fluid phase behavior of real systems are demonstrated. A particular effort is made to introduce the reader to expli- cit formulations of intermolecular interaction models and to show how these models influence the properties of fluid sy- stems. The established methods of statistical mechanics - computer simulation, perturbation theory, and numerical in- tegration - are discussed in a style appropriate for newcom- ers and are extensively applied. Numerous worked examples illustrate how practical calculations should be carried out.

    International Nuclear Information System (INIS)

    Following the general principles of both Newton's mechanics and Maxwell's electrodynamics, a new approach to basic equations of physics is presented. The new basic equations express fundamental laws of physics and are free from any physical constants. The necessary constants appear only through some kind of constitutive relations and by considering special solutions of the basic equations. The presented approach admits a new interpretation of fundamental physical constants, such as the Planck gravitational ones. 4 refs. (author)

    1985-01-01

    This book is intended as an introduction to plasma physics at a level suitable for advanced undergraduates or beginning postgraduate students in physics, applied mathematics or astrophysics. The main prerequisite is a knowledge of electromagnetism and of the associated mathematics of vector calculus. SI units are used throughout. There is still a tendency amongst some plasma physics researchers to· cling to C.g.S. units, but it is the author's view that universal adoption of SI units, which have been the internationally agreed standard since 1960, is to be encouraged. After a short introductory chapter, the basic properties of a plasma con­ cerning particle orbits, fluid theory, Coulomb collisions and waves are set out in Chapters 2-5, with illustrations drawn from problems in nuclear fusion research and space physics. The emphasis is on the essential physics involved and (he theoretical and mathematical approach has been kept as simple and intuitive as possible. An attempt has been made to draw attention t...

    2009-07-28

    Large eddy simulation (LES) is now seen more and more as a viable alternative to current industrial practice, usually based on problem-specific Reynolds-averaged Navier-Stokes (RANS) methods. Access to detailed flow physics is attractive to industry, especially in an environment in which computer modelling is bound to play an ever increasing role. However, the improvement in accuracy and flow detail has substantial cost. This has so far prevented wider industrial use of LES. The purpose of the applied LES discussion meeting was to address questions regarding what is achievable and what is not, given the current technology and knowledge, for an industrial practitioner who is interested in using LES. The use of LES was explored in an application-centred context between diverse fields. The general flow-governing equation form was explored along with various LES models. The errors occurring in LES were analysed. Also, the hybridization of RANS and LES was considered. The importance of modelling relative to boundary conditions, problem definition and other more mundane aspects were examined. It was to an extent concluded that for LES to make most rapid industrial impact, pragmatic hybrid use of LES, implicit LES and RANS elements will probably be needed. Added to this further, highly industrial sector model parametrizations will be required with clear thought on the key target design parameter(s). The combination of good numerical modelling expertise, a sound understanding of turbulence, along with artistry, pragmatism and the use of recent developments in computer science should dramatically add impetus to the industrial uptake of LES. In the light of the numerous technical challenges that remain it appears that for some time to come LES will have echoes of the high levels of technical knowledge required for safe use of RANS but with much greater fidelity.

    In this paper, it is argued that theoretical physics is more akin to an organism than to a rigid structure.It is in this sense that the epithet, "sick", applies to it. It is argued that classical physics is a model of a healthy science, and the degree of sickness of modern physics is measured accordingly. The malady is located in the relationship between mathematics and physical meaning in physical theory.

    Richmond, Peter; Hutzler, Stefan

    2013-01-01

    An understanding of the behaviour of financial assets and the evolution of economies has never been as important as today. This book looks at these complex systems from the perspective of the physicist. So called 'econophysics' and its application to finance has made great strides in recent years. Less emphasis has been placed on the broader subject of macroeconomics and many economics students are still taught traditional neo-classical economics. The reader is given a general primer in statistical physics, probability theory, and use of correlation functions. Much of the mathematics that is developed is frequently no longer included in undergraduate physics courses. The statistical physics of Boltzmann and Gibbs is one of the oldest disciplines within physics and it can be argued that it was first applied to ensembles of molecules as opposed to being applied to social agents only by way of historical accident. The authors argue by analogy that the theory can be applied directly to economic systems comprising...

    针对当前蝴蝶彩色效果绘制方法的真实感问题,提出一种应用薄膜干涉模型的真实感绘制方法。首先根据蝴蝶表面脊突结构构造多层薄膜模型;然后利用多层薄膜干涉原理模拟光在薄膜内部的多次反射、透射形成的混合散射特性,其中,菲涅尔公式被引入以解释反射或透射波的幅值变化,微表面散射因子被创造性地引入来模拟蝴蝶粗糙表面的各向异性特性;最后通过全波长光谱建模增强干涉效果,在此基础上还将该算法与光线追踪渲染框架相结合,构建了可应用于光线追踪器的波动双向散射分布函数干涉模型,以精确地模拟光的幅值和相位变动。实验结果表明,该模型能够有效地绘制出较为逼真的蝴蝶彩色效果。%To address the problems in realistic rendering of butterfly iridescences in computer graphics, this paper proposes a photorealistic simulation method, based on the thin film interference model. The method firstly constructs the multilayer film model, according to the ridge microstructures on butterfly wings; then it applies the multilayer film interference principle to model the mixed scattering characteristics of multiple reflections and transmissions of light inside films; The Fresnel formulae is employed to explain the amplitude variations of reflected or transmitted wave, and the microfacet scattering factor is creatively incorporated to model the anisotropic properties of rough surfaces of butterflies; finally, we augment the interference effects by full wavelength spectrum modeling and further combine the method with a ray tracing framework to construct the wave bidirectional scattering distribution function interference model, to accurately render the amplitude and phase variations of light. The experimental results demonstrate that our method can efficiently model the photorealistic iridescent colors of butterflies.

Eventually, following the EURONS advice, the merge of NEEN and SEEN was decided by representatives of both networks and, in 2004, a common network EWON (East - West Outreach) was included in the EURONS initiative. The indicated EU financial contribution to EWON includes only the support of NEEN, whereas SEEN, for practical reasons, is financed separately. The nuclear physics activity in Poland can be conveniently divided into a few subgroups: - experimental nuclear physics using local facilities; - experimental nuclear physics using external facilities; - theoretical nuclear physics; - applications of nuclear physics to other domains of science; - medical applications. Most of these activities are presented in this report, at least partly, in the form of review articles and short communications. The special place in the Polish nuclear physics landscape occupies the theoretical physics. Not limited by severe financial restrictions which affects local experimental facilities, the flourishing of this domain is especially evident in the nuclear structure theory

  5. Bologna Process: Apply or Not Apply

    Directory of Open Access Journals (Sweden)

    Muzaffer ELMAS

    2012-01-01

    Full Text Available There are lots of studies carried on education and training all over the world. U.S., Japan, Australia, East Asia and Europe continue this work in diff erent ways, but the main idea is the same. Here, the main idea is designing and sustaining educational systems based on learning outcomes, student centered approaches, system evaluation and quality cycles rather than inputs. Studies carried out in parallel with developments in the world are made under European Higher Education Area/Bologna Process. Th e aim here is to have graduates who are world citizens open to change. In recent years, in parallel with the changes in the world, especially based on Bologna Process reforms, comprehensive studies such as National Qualifications Framework, ECTS credits, student exchange programs and quality assurance systems are carried out in Turkey. Challenges, problems and bureaucracy make diff icult to sustain these important studies. Create a cycle in order to ensure the sustainability of the quality of this work is the most important step. A university management and evaluation scheme is consisting of corporate figures such as student, academic staff , physical infrastructure and financial parameters, and process qualities for student achievement, scientific research and community share, and their results shaped by managerial and behavioral capability of the system. Goals, objectives and performance in activities of individuals, departments and faculty of the universities are gett ing more important to identify and evaluate in certain periods. Th is challenging work having high bureaucracy strains university management and other stakeholders, and increases resistance to the quality processes. Establishing systems to ensure the sustainable quality gains importance as understanding and implementing the change in the world. Operating these quality processes with a systematic approach based on web technologies will result in reduced work load, increased

    Most teachers want students to think about their course content not only during class but also throughout their day. So, how do you get your students to see how what they learn in class applies to their lives outside of class? As physics teachers, we are fortunate that our students are continually surrounded by our content. How can we get them to notice the physics around them? How can we get them to make connections between the classroom content and their everyday lives? We would like to offer a few suggestions, Physics Take-Outs, to solve this problem.

Following each vote, the students are allowed to discuss the question among each other and a second vote is taken. The question is then answered by performing a demonstration experiment. This procedure is used to encourage students to discuss how the laws of physics are applied to real physical situations and to learn from each other. Demonstrations of this type have been used successfully in a large range of classes at the University of Maryland, and have also been used to pique the interest of pre-college students in taking physics classes.

    The recent trend in the application of mathematics to biological sciences is discussed in historical perspective. It is suggested that this new development should be regarded as a natural evolution of applied mathematics in the expansion of its scope. The mathematical concepts and methods to be used are not expected to be substantially different from those used in traditional applied mathematics. For illustration, we sketch an application of the kinetic theory of the study of dissipative systems to the study of the structure and function of protein molecules. The traditional concepts and methods of statistical physics can be successfully applied to yield predictions for comparison with empirical data.

    Full Text Available In this qualitative research study interviews conducted with elite participants serve to reveal the underlying elements that unite the richly diverse emerging field of Applied Literature. The basic interpretative qualitative method included a thematic analysis of data from the interviews yielding numerous common elements that were then distilled into key themes that elucidated the beneficial effects of engaging consciously with literature. These themes included developing a stronger sense of self in balance with an increasing connection with community; providing a safe container to engage challenging and potentially overwhelming issues from a stance of empowered action; and fostering a healing space for creativity. The findings provide grounds for uniting the work being done in a range of helping professions into a cohesive field of Applied Literature, which offers effective tools for healing, transformation and empowerment.Keywords: Applied Literature, Bibliotherapy, Poetry Therapy, Arts in Corrections, Arts in Medicine

    Science.gov (United States)

    Richmond, Stephen H

    2016-07-01

    The question of how to place psychoanalysis in relation to science has been debated since the beginning of psychoanalysis and continues to this day. The author argues that psychoanalysis is best viewed as a form of applied art (also termed applied aesthetics) in parallel to medicine as applied science. This postulate draws on a functional definition of modernity as involving the differentiation of the value spheres of science, art, and religion. The validity criteria for each of the value spheres are discussed. Freud is examined, drawing on Habermas, and seen to have erred by claiming that the psychoanalytic method is a form of science. Implications for clinical and metapsychological issues in psychoanalysis are discussed. PMID:27428582

    2010-01-01

    This paper presents experimental results of the implementation of network steganography method called RSTEG (Retransmission Steganography). The main idea of RSTEG is to not acknowledge a successfully received packet to intentionally invoke retransmission. The retransmitted packet carries a steganogram instead of user data in the payload field. RSTEG can be applied to many network protocols that utilize retransmissions. We present experimental results for RSTEG applied to TCP (Transmission Control Protocol) as TCP is the most popular network protocol which ensures reliable data transfer. The main aim of the performed experiments was to estimate RSTEG steganographic bandwidth and detectability by observing its influence on the network retransmission level.

    I show that Aristotelian physics is a correct approximation of Newtonian physics in its appropriate domain, in the same precise sense in which Newton theory is an approximation of Einstein's theory. Aristotelian physics lasted long not because it became dogma, but because it is a very good theory.

    Based on the concept of a physical system, this book offers a new philosophical interpretation of classical mechanics and the Special Theory of Relativity. According to Belkind's view the role of physical theory is to describe the motions of the parts of a physical system in relation to the motions of the whole. This approach provides a new perspective into the foundations of physical theory, where motions of parts and wholes of physical systems are taken to be fundamental, prior to spacetime, material properties and laws of motion. He defends this claim with a constructive project, deriving b

    Science.gov (United States)

    Guilaran, Ildefonso (Fonsie) J.

    2012-01-01

    When I was an undergraduate physics major, I would often stay up late with my physics major roommate as we would digest the physics content we were learning in our courses and explore our respective imaginations armed with our new knowledge. Such activity during my undergraduate years was confined to informal settings, and the first formal creativity assignment in my physics education did not come until well into my graduate years when my graduate advisor demanded that I write a prospectus for my dissertation. I have often lamented the fact that the first formal assignment in which I was required to be creative, take responsibility for my own learning and research objectives, and see them to completion during my physics education came so late, considering the degree to which creative attributes are celebrated in the personalities of great physicists. In this essay I will apply some of the basic concepts as defined by creativity-related psychology literature to physics pedagogy, relate these concepts to the exchanges in this journal concerning Michael Sobel's paper "Physics for the Non-Scientist: A Middle Way," and provide the framework for a low-overhead creativity assignment that can easily be implemented at all levels of physics education.

    CERN Document Server

    Mahmoud, Magdi S

    2012-01-01

    Applied Control System Design examines several methods for building up systems models based on real experimental data from typical industrial processes and incorporating system identification techniques. The text takes a comparative approach to the models derived in this way judging their suitability for use in different systems and under different operational circumstances. A broad spectrum of control methods including various forms of filtering, feedback and feedforward control is applied to the models and the guidelines derived from the closed-loop responses are then composed into a concrete self-tested recipe to serve as a check-list for industrial engineers or control designers. System identification and control design are given equal weight in model derivation and testing to reflect their equality of importance in the proper design and optimization of high-performance control systems. Readers’ assimilation of the material discussed is assisted by the provision of problems and examples. Most of these e...

  12. Applied String Theory

    CERN Document Server

    Schimmrigk, Rolf

    2008-01-01

    This is a review. Comments are welcome. The observation that the structure of string theory is rich enough to include the standard model in rough outline is an old one, starting with the early constructions of free field constructions, orbifold theories, and in particular Calabi-Yau compactifications in the late 1980s and early 1990s. At the time these constructions provided a large collection of different vacua, with thousands of explicitly constructed Calabi-Yau manifolds, and estimates of vast numbers of bosonic models, each one associated with its own moduli space. It was clear even then that it would be impossible to systematically search this string vacua landscape. This, however, is not a fundamental problem. Adopting the point of view that any physical theory has to describe not only our universe, but all possible consistent universes, leads to the obvious strategy of using some phenomenological input to select viable models among the ocean of models that obviously do not describe physics as we know i...

    2013-02-01

    Atomistic metaphysics motivated an explanatory strategy which science has pursued with great success since the scientific revolution. By decomposing matter into its atomic and subatomic parts physics gave us powerful explanations and accurate predictions as well as providing a unifying framework for the rest of science. The success of the decompositional strategy has encouraged a widespread conviction that the physical world forms a compositional hierarchy that physics and other sciences are progressively articulating. But this conviction does not stand up to a closer examination of how physics has treated composition, as a variety of case studies will show.

  18. Applied ALARA techniques

    International Nuclear Information System (INIS)

    The presentation focuses on some of the time-proven and new technologies being used to accomplish radiological work. These techniques can be applied at nuclear facilities to reduce radiation doses and protect the environment. The last reactor plants and processing facilities were shutdown and Hanford was given a new mission to put the facilities in a safe condition, decontaminate, and prepare them for decommissioning. The skills that were necessary to operate these facilities were different than the skills needed today to clean up Hanford. Workers were not familiar with many of the tools, equipment, and materials needed to accomplish:the new mission, which includes clean up of contaminated areas in and around all the facilities, recovery of reactor fuel from spent fuel pools, and the removal of millions of gallons of highly radioactive waste from 177 underground tanks. In addition, this work has to be done with a reduced number of workers and a smaller budget. At Hanford, facilities contain a myriad of radioactive isotopes that are 2048 located inside plant systems, underground tanks, and the soil. As cleanup work at Hanford began, it became obvious early that in order to get workers to apply ALARA and use hew tools and equipment to accomplish the radiological work it was necessary to plan the work in advance and get radiological control and/or ALARA committee personnel involved early in the planning process. Emphasis was placed on applying,ALARA techniques to reduce dose, limit contamination spread and minimize the amount of radioactive waste generated. Progress on the cleanup has,b6en steady and Hanford workers have learned to use different types of engineered controls and ALARA techniques to perform radiological work. The purpose of this presentation is to share the lessons learned on how Hanford is accomplishing radiological work

    Full Text Available Content-Based Image Retrieval (CBIR is a challenging task. Common approaches use only low-level features. Notwithstanding, such CBIR solutions fail on capturing some local features representing the details and nuances of scenes. Many techniques in image processing and computer vision can capture these scene semantics. Among them, the Scale Invariant Features Transform~(SIFT has been widely used in a lot of applications. This approach relies on the choice of several parameters which directly impact its effectiveness when applied to retrieve images. In this paper, we discuss the results obtained in several experiments proposed to evaluate the application of the SIFT in CBIR tasks.

Some contents practically impose the need for applied cartography which is especially true of international-political, military, geopolitical and transport issues. Therefore, mass communication media have been increasingly accepting and adopting specific cartography as significant content which successfully compete with the importance of the text itself – this is the case everywhere, including in Croatia. The French geographical-political-cartographic school is the model and exceptional accomplishment. It also has predecessors in the German/Nazi geopolitical school from the first half of the 20th century.

  16. Applied number theory

    CERN Document Server

    Niederreiter, Harald

    2015-01-01

    This textbook effectively builds a bridge from basic number theory to recent advances in applied number theory. It presents the first unified account of the four major areas of application where number theory plays a fundamental role, namely cryptography, coding theory, quasi-Monte Carlo methods, and pseudorandom number generation, allowing the authors to delineate the manifold links and interrelations between these areas.  Number theory, which Carl-Friedrich Gauss famously dubbed the queen of mathematics, has always been considered a very beautiful field of mathematics, producing lovely results and elegant proofs. While only very few real-life applications were known in the past, today number theory can be found in everyday life: in supermarket bar code scanners, in our cars’ GPS systems, in online banking, etc.  Starting with a brief introductory course on number theory in Chapter 1, which makes the book more accessible for undergraduates, the authors describe the four main application areas in Chapters...

    2015-01-01

    Focusing on high-dimensional applications, this 4th edition presents the tools and concepts used in multivariate data analysis in a style that is also accessible for non-mathematicians and practitioners.  It surveys the basic principles and emphasizes both exploratory and inferential statistics; a new chapter on Variable Selection (Lasso, SCAD and Elastic Net) has also been added.  All chapters include practical exercises that highlight applications in different multivariate data analysis fields: in quantitative financial studies, where the joint dynamics of assets are observed; in medicine, where recorded observations of subjects in different locations form the basis for reliable diagnoses and medication; and in quantitative marketing, where consumers’ preferences are collected in order to construct models of consumer behavior.  All of these examples involve high to ultra-high dimensions and represent a number of major fields in big data analysis. The fourth edition of this book on Applied Multivariate ...

  18. Physics: quantum mechanics

    International Nuclear Information System (INIS)

    From important experiment descriptions (sometimes, intentionally simplified), the essential concepts in Quantum Mechanics are first introduced. Wave function notion is described, Schroedinger equation is established, and, after applications rich in physical signification, quantum state and Hilbert space formalism are introduced, which will help to understand many essential phenomena. Then the quantum mechanic general formulation is written and some important consequences are deduced. This formalism is applied to a simple physical problem series (angular momentum, hydrogen atom, etc.) aiming at assimilating the theory operation and its application

    This book is the first to offer a systematic account of the role of language in the development and interpretation of physics. An historical-conceptual analysis of the co-evolution of mathematical and physical concepts leads to the classical/quatum interface. Bohrian orthodoxy stresses the indispensability of classical concepts and the functional role of mathematics. This book analyses ways of extending, and then going beyond this orthodoxy orthodoxy. Finally, the book analyzes how a revised interpretation of physics impacts on basic philosophical issues: conceptual revolutions, realism, and r

    2005-01-01

    As 2005, the International Year of Physics, comes to an end, two physicists working primarily in geophysical research reflect on how geophysics is not an applied physics. Although geophysics has certainly benefited from progress in physics and sometimes emulated the reductionist program of mainstream physics, it has also educated the physics community about some of the generic behaviors of strongly nonlinear systems. Dramatic examples are the insights we have gained into the ``emergent'' phenomena of chaos, cascading instabilities, turbulence, self-organization, fractal structure, power-law variability, anomalous scaling, threshold dynamics, creep, fracture, and so on. In all of these examples, relatively simple models have been able to explain the recurring features of apparently very complex signals and fields. It appears that the future of the intricate relation between physics and geophysics will be as exciting as its past has been characterized by a mutual fascination.

  13. Applied quantum cryptography

    International Nuclear Information System (INIS)

    Using the quantum properties of single photons to exchange binary keys between two partners for subsequent encryption of secret data is an absolutely novel technology. Only a few years ago quantum cryptography - or better: quantum key distribution - was the domain of basic research laboratories at universities. But during the last few years things changed. QKD left the laboratories and was picked up by more practical oriented teams that worked hard to develop a practically applicable technology out of the astonishing results of basic research. One major milestone towards a QKD technology was a large research and development project funded by the European Commission that aimed at combining quantum physics with complementary technologies that are necessary to create a technical solution: electronics, software, and network components were added within the project SECOQC (Development of a Global Network for Secure Communication based on Quantum Cryptography) that teamed up all expertise on European level to get a technology for future encryption. The practical application of QKD in a standard optical fibre network was demonstrated October 2008 in Vienna, giving a glimpse of the future of secure communication. Although many steps have still to be done in order to achieve a real mature technology, the corner stone for future secure communication is already laid. QKD will not be the Holy Grail of security, it will not be able to solve all problems for evermore. But QKD has the potential to replace one of the weakest parts of symmetric encryption: the exchange of the key. It can be proven that the key exchange process cannot be corrupted and that keys that are generated and exchanged quantum cryptographically will be secure for ever (as long as some additional conditions are kept). This book will show the state of the art of Quantum Cryptography and it will sketch how it can be implemented in standard communication infrastructure. The growing vulnerability of sensitive

  17. Essays in applied microeconomics

    Science.gov (United States)

    Wang, Xiaoting

    In this dissertation I use Microeconomic theory to study firms' behavior. Chapter One introduces the motivations and main findings of this dissertation. Chapter Two studies the issue of information provision through advertisement when markets are segmented and consumers' price information is incomplete. Firms compete in prices and advertising strategies for consumers with transportation costs. High advertising costs contribute to market segmentation. Low advertising costs promote price competition among firms and improves consumer welfare. Chapter Three also investigates market power as a result of consumers' switching costs. A potential entrant can offer a new product bundled with an existing product to compensate consumers for their switching cost. If the primary market is competitive, bundling simply plays the role of price discrimination, and it does not dominate unbundled sales in the process of entry. If the entrant has market power in the primary market, then bundling also plays the role of leveraging market power and it dominates unbundled sales. The market for electric power generation has been opened to competition in recent years. Chapter Four looks at issues involved in the deregulated electricity market. By comparing the performance of the competitive market with the social optimum, we identify the conditions under which market equilibrium generates socially efficient levels of electric power. Chapter Two to Four investigate the strategic behavior among firms. Chapter Five studies the interaction between firms and unemployed workers in a frictional labor market. We set up an asymmetric job auction model, where two types of workers apply for two types of job openings by bidding in auctions and firms hire the applicant offering them the most profits. The job auction model internalizes the determination of the share of surplus from a match, therefore endogenously generates incentives for an efficient division of the matching surplus.

  2. Lectures on LHC physics

    CERN Document Server

    Plehn, Tilman

    2015-01-01

    With the discovery of the Higgs boson, the LHC experiments have closed the most important gap in our understanding of fundamental interactions, confirming that such interactions between elementary particles can be described by quantum field theory, more specifically by a renormalizable gauge theory. This theory is a priori valid for arbitrarily high energy scales and does not require an ultraviolet completion. Yet, when trying to apply the concrete knowledge of quantum field theory to actual LHC physics - in particular to the Higgs sector and certain regimes of QCD - one inevitably encounters an intricate maze of phenomenological know-how, common lore and other, often historically developed intuitions about what works and what doesn’t. These lectures cover three aspects to help understand LHC results in the Higgs sector and in searches for physics beyond the Standard Model: they discuss the many facets of Higgs physics, which is at the core of this significantly expanded second edition; then QCD, to the deg...

  3. Essays in applied economics

    Science.gov (United States)

    Arano, Kathleen

    Three independent studies in applied economics are presented. The first essay looks at the US natural gas industrial sector and estimates welfare effects associated with the changes in natural gas regulatory policy over the past three decades. Using a disequilibrium model suited to the natural gas industry, welfare transfers and deadweight losses are calculated. Results indicate that deregulation policies, beginning with the NGPA of 1978, have caused the industry to become more responsive to market conditions. Over time, regulated prices converge toward the estimated equilibrium prices. As a result of this convergence, deadweight losses associated with regulation are also diminished. The second essay examines the discounted utility model (DU), the standard model used for intertemporal decision-making. Prior empirical studies challenge the descriptive validity of the model. This essay addresses the four main inconsistencies that have been raised: domain dependence, magnitude effects, time effects, and gain/loss asymmetries. These inconsistencies, however, may be the result of the implicit assumption of linear utility and not a failure of the DU model itself. In order to test this hypothesis, data was collected from in-class surveys of economics classes at Mississippi State University. A random effects model for panel data estimation which accounts for individual specific effects was then used to impute discount rates measured in terms of dollars and utility. All four inconsistencies were found to be present when the dollar measures were used. Using utility measures of the discount rate resolved the inconsistencies in some cases. The third essay brings together two perspectives in the study of religion and economics: modeling religious behavior using economic tools and variables, and modeling economic behavior using religious variables. A system of ordered probit equations is developed to simultaneously model religious activities and economic outcomes. Using data

  4. Learning Physics

    International Nuclear Information System (INIS)

    Full Text:The issue of Teaching physics vs Learning physics in our institutions of higher learning will be discussed. Physics is taught mainly by frontal lectures an old (and proven) method. The great advancements of the Information Age are introduced by exposing the students to vast amounts of computerized information and directing them to numerical problem solving by interacting with the computer. These modern methods have several drawbacks: 1. Students get the impression of easy material acquisition while in fact it becomes superficial. 2. There is little integration of topics that are taught in different courses. 3. Insufficient interest is built among undergraduate students to pursue studies that involve deeper thinking and independent research (namely, studies towards a doctoral degree). Learning physics is a formative process in the education of physicists, natural scientists and engineers. It must be based on discussions and exchange of ideas among the students, since understanding the studied material means being able to explain it to a colleague. Some universities in the US initiated programs of learning physics by creating an environment in which small groups of students are engaged in discussing material, jointly solving problems and jointly conducting simulated experiments. This is done under the supervision of a mentor. Suggestions for implementing this method in Israel will be discussed

    Cunningham, Mark A

    2015-01-01

    In this introductory text, physics concepts are introduced as a means of understanding experimental observations, not as a sequential list of facts to be memorized. The book is structured around the key scientific discoveries that led to much of our current understanding of the universe. Numerous exercises are provided that utilize Mathematica software to help students explore how the language of mathematics is used to describe physical phenomena. Topics requiring quantum mechanics for a more complete explanation are identified but not pursued. In a departure from the traditional methodology and subject matter used in introductory physics texts, this is organized in a manner that will facilitate a guided discovery style of instruction. Students will obtain much more detailed information about fewer topics and will also gain proficiency with Mathematica, a powerful tool with many potential uses in subsequent courses.

  12. Physics, philosophy and environment

    International Nuclear Information System (INIS)

    Physics and philosophy has join developments since the Jonios. The present article tries to analyze some of the philosophical problems that arise of the classic and contemporary physics and that affect the environmental vision. In general, it can be said that the discoveries of the physics has meant a progressive desplatonization of the western world, including the remaining of Platon that is included in Aristoteles philosophy. From the analysis some problems arise that is worthwhile to emphasize. Above all the relationship between determinism and random theory, from the environmental perspective it is necessary to wonder if it is licit to apply these concepts to man. With it the problem of freedom arise, attacked by Spinoza, but carefully protected by Kant's philosophy. Their acceptance supposes, however, the division between man and the cultural schizophrenia. Is it possible to explain freedom from the physics, such as was pretended by Epicuro or Prigonine? Has nature a wide field of freedom as it is assumed in some of the currents of contemporary physics? All of them are questions that the environmental thought has to confront, although it cannot solve them

A very short overview of these activities is given in this issue of the ATLAS News Letter, while the various topics will be described in more detail in the next issues. The Physics and Combined Performance groups are working in four main areas: 1) Assess the ATLAS potential for physics, with emphasis on new channels and ideas. Recent examples are Extra-dimensions, invisible Higgs decays, heavy ion physics, the expected potential of a "Super-LHC" running at a luminosity of 10^35, etc.. 2) Improve the understanding of the detector performance and optimise the reconstruction algorithms. Examples of issues in the pipeline are: can we tag charm-jet ? What can we gain in the jet energy resolution by combining the calorimeter and tracker information to reconstruct the jet energy ? 3) Follow detector changes and detector-related issues and monitor the impact on the perform...

  2. After physics

    CERN Document Server

    Albert, David Z

    2015-01-01

    After Physics presents ambitious new essays about some of the deepest questions at the foundations of physics, by the physicist and philosopher David Albert. The book’s title alludes to the close connections between physics and metaphysics, much in evidence throughout these essays. It also alludes to the work of imagining what it would be like for the project of physical science—considered as an investigation into the fundamental laws of nature—to be complete. Albert argues that the difference between the past and the future—traditionally regarded as a matter for metaphysical or conceptual or linguistic or phenomenological analysis—can be understood as a mechanical phenomenon of nature. In another essay he contends that all versions of quantum mechanics that are compatible with the special theory of relativity make it impossible, even in principle, to present the entirety of what can be said about the world as a narrative sequence of “befores” and “afters.” Any sensible and realistic way of...

    1. Physics competitions: aims and realizations One aim of physics competitions is to increase the interest of young students, primarily at upper secondary level, to physics and natural sciences in general. A competition has motivational aspects known usually from sports events or games—comparing one's own ability with others, of course with the desire to be better and to win. If competitions reach nationwide and even international levels, additional stimulation is created. Competitions provide greatest attraction to possible winners, to the group of gifted people in a particular field. This implies that science contests are excellent tools for the promotion of talented students. Traditional teaching has been shown to have problems in supporting this group of students. Very often teachers are overstretched with the demands of teaching both low- and high-level students. Extracurricular activities are therefore a good chance to relieve the teacher, and to give talented students the opportunity for appropriate training and challenge. The competitions, however, have a broader impact and address more young people than one might guess from the statements above. Training courses and selection at school level give a larger group of students extra and, to some extent, complimentary education in physics. The degree of complexity of the tasks corresponds very often to the standards of the next level of education in the school system. Interestingly, many physics competitions have their origin in countries beyond the former Iron Curtain. They started as regional and national tournaments, were joined by neighbouring countries and have grown, in some cases, to events with participants from more than 80 countries. Although the features mentioned above are common to the different competitions, there are distinct differences between them [1]. The International Physics Olympiad (IPhO) is the oldest international physics competition for students at upper secondary level [2]. It dates

    significantly reduced soil bulk density and obviously increased soil total porosity and capillary porosity, indicative of 6.62%, 11.19%, 16.45% and 7.97% decreases in soil bulk density compared to the treatments of CK, I60, I30 and I30S, respectively. The I60S treatment also evidently increased MBC and MBN contents and significantly enhanced microbial respiration, showing 13.89%, 24.24%, 41.38% and 12.33% increases in microbial respiration rate over the treatments of CK, I60, I30 and I30S, respectively. At the same time, the metabolic quotient was reduced by the I60S treatment, demonstrating 5.96%, 8.84%, 11.72% and 4.78% decreases, respectively. Additionally, the volume growth rate of the I60S treatment also reached the maximum, which had significant differences with other treatments (P<0.05). However, in the I30S treatment, less effect on the forest soil characteristics and the volume growth were observed than that in the I60S treatment. The correlation analysis showed that the volume growth rate was extremely significantly correlated with capillary porosity and metabolic quotient, and had significant correlation with soil bulk density, MBC and MBN contents and microbial respiration. In conclusion, the proper water-saving irrigation measure (60% border irrigation quantity co-applied with super absorbent polymers) is beneficial to improving soil physical environment and enhancing microbial activity in forest soil, as well as the growth of poplar.

    The mathematical representation of the physical objects determines which mathematical branch will be applied during the physical analysis in the systems studied. The difference among non-quantum physics, like classic or relativistic physics, and quantum physics, especially in quantum field theory, is nothing else than the difference between the mathematics that is used on both branches of the physics. A common physical and mathematical origin for the analysis of the different systems brings b...

    Ong, Rene A.

    2013-12-01

    Astroparticle physics is a rapidly developing field that has a high degree of overlap with particle physics and astronomy. This paper summarizes recent results and leading experiments in two selected areas: very high energy astrophysics and dark matter. Both areas have made great progress in the last 5 years due to improved instrumentation and a growing community. In very high energy astrophysics, many sources of GeV and TeV radiation have been detected and the challenge now is to fully understand the processes involved at these sites of extreme particle acceleration. In the area of dark matter, there is a close scientific connection between astroparticle experiments and the Large Hadron Collider (LHC). The combination of the LHC, direct-detection and indirect-detection experiments provide critical complementarity and unprecedented sensitivity in the quest to understand this deep mystery.

    CERN Document Server

    Scheck, Florian

    2013-01-01

    Scheck’s Quantum Physics presents a comprehensive introductory treatment, ideally suited for a two-semester course. Part One covers the basic principles and prime applications of quantum mechanics, from the uncertainty relations to many-body systems. Part Two introduces to relativistic quantum field theory and ranges from symmetries in quantum physics to electroweak interactions. Numerous worked-out examples as well as exercises, with solutions or hints, enables the book’s use as an accompanying text for courses, and also for independent study. For both parts, the necessary mathematical framework is treated in adequate form and detail. The book ends with appendices covering mathematical fundamentals and enrichment topics, plus selected biographical notes on pioneers of quantum mechanics and quantum field theory. The new edition was thoroughly revised and now includes new sections on quantization using the path integral method and on deriving generalized path integrals for bosonic and fermionic fields.

    2015-01-01

    This new edition is an enriched version of the textbook of fluid dynamics published more than 10 years ago. It retains the same physically oriented pedagogical perspective. This book emphasizes, as in the first edition, experimental inductive approaches and relies on the study of the mechanisms at play and on dimensional analysis rather than more formal approaches found in many classical textbooks in the field. The need for a completely new version also originated from the increase, over the last few decades, of the cross-overs between the mechanical and physical approaches, as is visible in international meetings and joint projects. Hydrodynamics is more widely linked today to other fields of experimental sciences: materials, environment, life sciences and earth sciences, as well as engineering sciences.

    International tests on competences, such as TIMSS or PISA, and knowledge of young students have revealed low average scores in many countries, often unexpectedly. One effective measure to increase the average standard of a population is to bring the last third of the group to a higher level. Therefore, many nations put some effort into this activity. This brings the danger that not enough attention is paid to students at the other end, those who are talented. Indeed, it is a very difficult task for a teacher to support the less able and at the same time challenge the gifted students, to lead them to the limits of their abilities and provide for a smooth transition to university study. Physics competitions have been proven to fulfil these last demands to a large degree, and therefore are an important additional and, to some extent, complementary tool for the promotion of talented students. This third special section on physics competitions in European Journal of Physics contains three papers, each dealing with a different form of science contest. The first continues the series of presentations of tasks performed at the International Young Physicists' Tournament, which was held in Vienna in 2011. First place went to the team from Singapore, and they have put their investigation on vertical oscillations of coupled magnets into written form (not required by the tournament, where an oral presentation and a defence and discussion are the central aspects). Their paper shows how rich in physics this problem is, and what level of solutions high-school students can already achieve. Sadly, those responsible for the organization of last year's International Physics Olympiad did not provide us with a report on this competition. This is unfortunate, since the Olympiad in Zagreb was very successful and, in particular, the experimental tasks were creative and demanding. Very similar to the aims and the execution of the Physics Olympiad is the International Olympiad on Astronomy

  17. Fusion Physics

    International Nuclear Information System (INIS)

    Recreating the energy production process of the Sun - nuclear fusion - on Earth in a controlled fashion is one of the greatest challenges of this century. If achieved at affordable costs, energy supply security would be greatly enhanced and environmental degradation from fossil fuels greatly diminished. Fusion Physics describes the last fifty years or so of physics and research in innovative technologies to achieve controlled thermonuclear fusion for energy production. The International Atomic Energy Agency (IAEA) has been involved since its establishment in 1957 in fusion research. It has been the driving force behind the biennial conferences on Plasma Physics and Controlled Thermonuclear Fusion, today known as the Fusion Energy Conference. Hosted by several Member States, this biennial conference provides a global forum for exchange of the latest achievements in fusion research against the backdrop of the requirements for a net energy producing fusion device and, eventually, a fusion power plant. The scientific and technological knowledge compiled during this series of conferences, as well as by the IAEA Nuclear Fusion journal, is immense and will surely continue to grow in the future. It has led to the establishment of the International Thermonuclear Experimental Reactor (ITER), which represents the biggest experiment in energy production ever envisaged by humankind.

    This text is designed for a calculus-based physics course at the beginning university and college level. It is written with the expectation that students have either taken or are currently taking a beginning course in calculus. Students taking a physics course based on this book should leave with a solid conceptual understanding of the fundamental physical laws and how these laws can be applied to solve many problems. The key word for this edition is "understanding." The third edition of this text remains rigorous while including a number of new pedagogical elements which emphasize conceptual understanding.

  3. Physics from information

    CERN Document Server

    Lee, Jae-Weon

    2010-01-01

    This is an ongoing review on my conjecture that information processing at causal horizons is the key ingredient of all physics. Assuming that information is fundamental and the information propagates with finite velocity, one can find that main physical laws such as Newton's second law and Einstein equation simply describe the energy-information relation (dE=TdS) for matter or space time crossing a causal horizon with temperature T for observers. Quantum mechanics arises from ignorance of the observers about matter crossing the horizon, which explains why superluminal communication is impossible even with quantum entanglement. This approach also explains the origin of Jacobson's thermodynamic formalism of Einstein gravity and Verlinde's entropic gravity. When applied to a cosmic causal horizon, the conjecture reproduces the observed dark energy and demands the zero cosmological constant.

  4. Equilibrium statistical physics

    Full Text Available Neutrosophy can be widely applied in physics and the like. For example, one of the reasons for 2011 Nobel Prize for physics is "for the discovery of the accelerating expansion of the universe through observations of distant supernovae", but according to neutrosophy, there exist seven or nine states of accelerating expansion and contraction and the neutrosophic state in the universe. Another two examples are "a revision to Gödel's incompleteness theorem by neutrosophy" and "six neutral (neutrosophic fundamental interactions". In addition, the "partial and temporary unified theory so far" is discussed (including "partial and temporary unified electromagnetic theory so far", "partial and temporary unified gravitational theory so far", "partial and temporary unified theory of four fundamental interactions so far", and "partial and temporary unified theory of natural science so far".

    International Nuclear Information System (INIS)

    The first Nobel Physics Prize, awarded in 1901, went to Wilhelm Röntgen for his discovery of X-rays in 1895. This, and the most recent physics Nobel, to Georges Charpak last year for his detector developments, span several generations of applied science. As well as helping to launch the science of atomic physics, Röntgen's discovery also marked the dawn of a medical science - radiography - using beams of various kinds to image what otherwise cannot be seen. Ever since, physicists and radiologists have worked hand in hand to improve imaging techniques and widen their medical applications

    The workshop on hydrogen bond was restarted changing its name to 'Hydrogen Physics' for grasping hydrogen bond from wider viewpoint and expecting the new development in this field hereafter. As the basic attitude, the phenomena related to hydrogen bond are reviewed from two different systems: hydrogen-lattice system and hydrogen-electron system. The Hydrogen Physics meeting was held on September 29 and 30, 1992, at National Laboratory for High Energy Physics, and 19 lectures were given. The themes were proton dynamics of hydrogen bond, water science and water with good taste, collective movement and fluctuation of water, neutron diffraction of water, hydrogen bond in water as seen from Raman scattering, electron and proton movements in organic crystals, new deuterium substitution effect of proton transfer in hydrogen bond in solids, infrared spectroscopy for one-dimensional hydrogen bond crystals, MSR in solid hydrogen, hydrogen in alkali metal-graphite intercalation compounds, lattice anomalies and Grueneisen parameters in high Tc superconducting salts, bio-substances and hydrogen, hydrogen bond net in nucleotide and control of crystalline structure change by hydrogen vapor pressure, ATP and structural change and crystal water of guanosine, spread of protons and electrons in hydrogen bond, anisotropy of loose scattering according to ice rule, high pressure effect and isotope mixed crystal effect of KHS crystals without hydrogen crystal network, state of motion and phase transformation of hydrogen in KDP, and development of hydrogen bond research by neutron scattering. This publication contains the papers and the transparencies presented at the meeting. (J.P.N.)

  10. Nucleon physics

    International Nuclear Information System (INIS)

    This book is an introduction to the interactions of nucleons with special regards to their contribution to nuclear forces. After a general description of the nuclear structure as a configuration of many nucleons the properties and interactions of nucleons are described with an excursion to the fundamental processes governing them. Then nuclear energy levels are considered. Thereafter nuclear energy-level transitions are described in the framework of the governing elementary processes. Finally nuclear reactions are considered in this framework. This book is suited as a supplement to a textbook in nuclear physics for students, who want to get a deeper insight in the fundamental processes in nuclei. (HSI)

    International Nuclear Information System (INIS)

    Is all hadronic physics ultimately describable by QCD. Certainly, many disparate phenomena can be understood within the QCD framework. Also certainly, there are important questions which are open, both theoretically (little guidance, as yet) and experimentally, regarding confinement. Are there dibaryons, baryonium, glueballs. In addition, there are experimental results which at present do not have an explanation. This talk, after a short section on QCD successes and difficulties, will emphasize two experimental topics which have recent results - glueball spectroscopy and exclusive reactions at large momentum transfer. Both are experimentally accessible in the AGS/LAMPF II/AGS II/TRIUMF II/SIN II energy domain

    International Nuclear Information System (INIS)

    The two main themes of this volume are the standard model of the fundamental interactions (and beyond) and astrophysics. The remarkable advances in the theoretical understanding and experimental confirmation of the standard model were reviewed in several lectures where the reader will find a thorough analysis of recent experiments as well as a detailed comparison of the standard model with experiment. On a more theoretical side, supersymmetry, supergravity and strings were discussed as well. The second theme concerns astrophysics where the school was quite successful in bridging the gap between this fascinating subject and more conventional particle physics

    Myre, W.C.; DeMontmollin, J.M. (Sandia National Labs., Albuquerque, NM (USA))

    1989-07-01

    Serious concern about physical protection of nuclear facilities began around 1972. R and D was initiated at Sandia National Laboratories which had developed techniques to protect weapons for many years. Special vehicles, convoy procedures, and a communications system previously developed for weapons shipments were improved and extended for shipments of other sensitive materials. Barriers, perimeter alarms, portal and internal control systems were developed, tested, and published in handbooks and presented at symposia. Training programs were initiated for U.S. and foreign personnel. Containment and surveillance techniques were developed for the IAEA. Presently emphasis is on computer security, active barriers, and techniques to prevent theft or sabotage by insiders .

  1. EDITORIAL: Physics competitions Physics competitions

    Science.gov (United States)

    Jordens, H.; Mathelitsch, L.

    2010-07-01

    This editorial opens the second special section on physics competitions in European Journal of Physics. In the first section last year, we asked for feedback on the idea of such a section and on the content of the articles. We received no answer whatsoever, which can be interpreted in two ways: the section is not interesting enough to raise motivation for feedback, or the reader is satisfied. Having no indication which scenario is the correct one, we are optimistic and favour the second. The section at hand contains three articles. Again, as last year, the organizer of the annual Olympiad reports on tasks and outcomes of this competition. The Olympiad took place in Merida, Mexico, and was by far the largest event with 316 contestants from 68 countries. Again, the predominance of Asian/Chinese students was manifest, showing how serious the training is taken by both their authorities and students. Unfortunately, the winners of the last International Young Physicists' Tournament (IYPT), the team from Korea, did not accept the offer to report on their prize-winning contribution. We are thankful that two students from Austria, who achieved second place with their team, took over and reported on the task which they presented in the finals of the competition. It connects the fields of sport and physics and explains a special move in skateboarding. The third contribution introduces a different competition, 'International Conference of Young Scientists'. On one hand, as in the Olympiad, it addresses individuals, not teams. On the other, as in the IYPT, students have several months to prepare and also the quality of the presentation is an important element of the judgment. In fact, this competition comes closer to real scientific research compared to the other events. Finally and again, we hope that this section will serve several purposes: To show the competitions as a very important tool in the support of gifted students. To raise awareness amongst university teachers, and

  2. Physics vs. computer science

    International Nuclear Information System (INIS)

    With computers becoming more frequently used in theoretical and experimental physics, physicists can no longer afford to be ignorant of the basic techniques and results of computer science. Computing principles belong in a physicist's tool box, along with experimental methods and applied mathematics, and the easiest way to educate physicists in computing is to provide, as part of the undergraduate curriculum, a computing course designed specifically for physicists. As well, the working physicist should interact with computer scientists, giving them challenging problems in return for their expertise. (orig.)

  3. Physical layer network coding

    DEFF Research Database (Denmark)

    Fukui, Hironori; Popovski, Petar; Yomo, Hiroyuki

    2014-01-01

    Physical layer network coding (PLNC) has been proposed to improve throughput of the two-way relay channel, where two nodes communicate with each other, being assisted by a relay node. Most of the works related to PLNC are focused on a simple three-node model and they do not take into account...... the impact of interference from other transmissions. Unlike these conventional studies, in this paper, we apply PLNC to a large-scale cellular network in the presence of intercell interference (ICI). In cellular networks, a terminal and a Base Station (BS) have different transmission power, which causes...

  4. Renormalization and plasma physics

    International Nuclear Information System (INIS)

    A review is given of modern theories of statistical dynamics as applied to problems in plasma physics. The derivation of consistent renormalized kinetic equations is discussed, first heuristically, later in terms of powerful functional techniques. The equations are illustrated with models of various degrees of idealization, including the exactly soluble stochastic oscillator, a prototype for several important applications. The direct-interaction approximation is described in detail. Applications discussed include test particle diffusion and the justification of quasilinear theory, convective cells, E vector x B vector turbulence, the renormalized dielectric function, phase space granulation, and stochastic magnetic fields

  8. Nuclear physics

    International Nuclear Information System (INIS)

    This book fills a gap in current literature by covering the increasing nuclear physics content of various A-level syllabuses. In section 1 we outline the background and early development of the subject, in section 2 we deal with nuclear properties and theories at a level suitable for the pre-university student. The majority of topics have been treated with the limited use of mathematics, this necessitating some simplification which we hope to have accomplished without undue error. A few topics have been developed mathematically, to some extent, e.g. series decay. While it is the purpose of a book at this level to introduce the reader to the facts and theories of nuclear physics, we have to recognise that any teacher of science, at any level, must attempt to instill in the young scientist a sense of responsibility and an understanding of the problems attendant on the technological applications are important. These problems have been touched on in the text but we hope the student will be persuaded to read further; for this purpose we have added a short list of suggested additional reading. A selection of A-level past paper questions has been included. (author)

  14. LHC Physics

    CERN Bulletin

    2010-01-01

    From quarks to yet unknown particles, CERN continues to explore new frontiers in physics. Thanks to some of the most complex instruments ever made in a laboratory, Nature can reveal its inner secrets to the scientists.   Mass is the amount of material in an object. Newton showed us that weight is proportional to mass, and Einstein showed that energy is related to mass through the famous equation E = mc2. When it comes to elementary particles, physicists are dealing with a very fundamental question: where does the mass come from?  Why do particles with no known structure have mass? The answer may lie in the so-called Higgs mechanism. According to this theory, a medium - called the Higgs field - spreads through all the Universe at all times. Particles acquire their mass by interacting with this field, such that those that interact strongly are heavier than those having a weaker interaction. The Higgs boson is th...

They describe entire classes of materials, such as viscid fluids and gases, elastic media, dielectrics or electrical con...

  17. Supercollider physics

    International Nuclear Information System (INIS)

    Several unsolved problems concerning backgrounds prevent one from claiming that some particular signal is clearly observable. One of the most critical issues concerns the observability of W's and Z's from their decays into hadronic jets. Many signals for new physics involve final states with W's or Z's (e.g. the minimal Higgs discussed in D). If one is restricted to observing the W's and Z's via their leptonic modes (which may not be possible for final states involving more than one W) only a small number of events will be detected - 5000 Z pairs decaying into ee and μμ results in only 18 detected events. The physics background to hadronic decays of W and Z is from QCD events with multiple jets. In the case of final states with 4 jets we have no reliable QCD estimate. Many particle searches (e.g. supersymmetric ones) involve signals which have missing transverse momentum, so the importance of hermetic detectors with 4 π coverage cannot be overstated. The difference between a pp and a proton-antiproton collider is limited to a few special cases where the presence of valence antiquarks in the anti-proton is important (for example is the production of a new W). In order to exploit this advantage a certain minimum luminosity is required. (approx. 5 x 1031 cm-2 sec-1 for √s = 40 TeV). A 40 TeV machine operating at a luminosity of at least 1032 cm-2 sec-1, seems capable of answering the fundamental questions surrounding the breaking of weak interactions. The same assurance cannot be given for a 10 TeV Machine at the same luminosity. 23 references, 23 figures
