    Full Text Available Cloud computing has been a tremendous innovation, through which applications became available online, accessible through an Internet connection and using any computing device (computer, smartphone or tablet. According to one of the most recent studies conducted in 2012 by Everest Group and Cloud Connect, 57% of companies said they already use SaaS application (Software as a Service, and 38% reported using standard tools PaaS (Platform as a Service. However, in the most cases, the users of these solutions highlighted the fact that one of the main obstacles in the development of this technology is the fact that, in cloud, the application is not available without an Internet connection. The new challenge of the cloud system has become now the offline, specifically accessing SaaS applications without being connected to the Internet. This topic is directly related to user productivity within companies as productivity growth is one of the key promises of cloud computing system applications transformation.

    2011-01-01

    We describe the current state-of-the-art in Trusted Computing Technologies - focusing mainly on Intel's Trusted Execution Technology (TXT). This document is based on existing documentation and tests of two existing TXT-based systems: Intel's Trusted Boot and Invisible Things Lab's Qubes OS. We describe what features are lacking in current implementations, describe what a mature system could provide, and present a list of developments to watch. Critical systems perform operation-critical computations on high importance data. In such systems, the inputs, computation steps, and outputs may be highly sensitive. Sensitive components must be protected from both unauthorized release, and unauthorized alteration: Unauthorized users should not access the sensitive input and sensitive output data, nor be able to alter them; the computation contains intermediate data with the same requirements, and executes algorithms that the unauthorized should not be able to know or alter. Due to various system requirements, such critical systems are frequently built from commercial hardware, employ commercial software, and require network access. These hardware, software, and network system components increase the risk that sensitive input data, computation, and output data may be compromised.

    How well the computer site manager avoids future dangers and takes advantage of future opportunities depends to a considerable degree on how much anticipatory information he has available. People who rise in management are expected with each successive promotion to concern themselves with events further in the future. It is the function of technology projection to increase this stock of information about possible future developments in order to put planning and decision making on a more rational basis. Past efforts at computer technology projections have an accuracy that declines exponentially with time. Thus, precisely defined technology projections beyond about three years should be used with considerable caution. This paper reviews both subjective and objective methods of technology projection and gives examples of each. For an integrated view of future prospects in computer technology, a framework for technology projection is proposed.

    Nakayama, Wataru

    The rapid growth of data processing speed in computers has been sustained by the advances in cooling technology. This article first presents a review of the published data of heat loads in recent Japanese large-scale computers. The survey indicates that, since around 1980, the high-level integration of microelectronic circuits has brought about almost four fold increase in the power dissipation from logic chips. The integration also has invited the evolutions of multichip modules and new schemes of electronic interconnections. Forced convection air-cooling and liquid cooling coupled with thermal connectors are discussed with reference to the designs employed in actual computers. More advanced cooling schemes are also discussed. Finally, the importance of thermal environmental control of computer rooms is emphasized.

    Computational Fluid Dynamics (or CFD) methods are very familiar to the research community. Even the general public has had some exposure to CFD images, primarily through the news media. However, very little attention has been paid to CST--Computational Structures Technology. Yet, no important design can be completed without it. During the first half of this century, researchers only dreamed of designing and building structures on a computer. Today their dreams have become practical realities as computational methods are used in all phases of design, fabrication and testing of engineering systems. Increasingly complex structures can now be built in even shorter periods of time. Over the past four decades, computer technology has been developing, and early finite element methods have grown from small in-house programs to numerous commercial software programs. When coupled with advanced computing systems, they help engineers make dramatic leaps in designing and testing concepts. The goals of CST include: predicting how a structure will behave under actual operating conditions; designing and complementing other experiments conducted on a structure; investigating microstructural damage or chaotic, unpredictable behavior; helping material developers in improving material systems; and being a useful tool in design systems optimization and sensitivity techniques. Applying CST to a structure problem requires five steps: (1) observe the specific problem; (2) develop a computational model for numerical simulation; (3) develop and assemble software and hardware for running the codes; (4) post-process and interpret the results; and (5) use the model to analyze and design the actual structure. Researchers in both industry and academia continue to make significant contributions to advance this technology with improvements in software, collaborative computing environments and supercomputing systems.

  18. Reviews of computing technology: Object-oriented technology

    Energy Technology Data Exchange (ETDEWEB)

    Skeen, D.C.

    1993-03-01

    A useful metaphor in introducing object-oriented concepts is the idea of a computer hardware manufacturer assembling products from an existing stock of electronic parts. In this analogy, think of the parts as pieces of computer software and of the finished products as computer applications. Like its counterpart, the object is capable of performing its specific function in a wide variety of different applications. The advantages to assembling hardware using a set of prebuilt parts are obvious. The design process is greatly simplified in this scenario, since the designer needs only to carry the design down to the chip level, rather than to the transistor level. As a result, the designer is free to develop a more reliable and feature rich product. Also, since the component parts are reused in several different products, the parts can be made more robust and subjected to more rigorous testing than would be economically feasible for a part used in only one piece of equipment. Additionally, maintenance on the resulting systems is simplified because of the part-level consistency from one type of equipment to another. The remainder of this document introduces the techniques used to develop objects, the benefits of the technology, outstanding issues that remain with the technology, industry direction for the technology, and the impact that object-oriented technology is likely to have on the organization. While going through this material, the reader will find it useful to remember the parts analogy and to keep in mind that the overall purpose of object-oriented technology is to create software parts and to construct applications using those parts.

    Optics has a number of deep analogies with main principles of Computational Intelligence. We can see strong analogies between basic optical phenomena, used in Fourier-holography, and mathematical foundations of Fuzzy Set Theory. Also, analogies between optical holography technique and principles of Neural Networks Paradigm can be seen. Progress in new holographic recording media with self-developing property leads to Evolutionary Computations holographic realization. Based on these analogies we review holographic techniques from two points of view: Fuzzy Logic and Fuzzy relations.

    The book advances the premise that the cytoskeleton is the cell's nervous system, the biological controller/computer. If indeed cytoskeletal dynamics in the nanoscale (billionth meter, billionth second) are the texture of intracellular information processing, emerging ''NanoTechnologies'' (scanning tunneling microscopy, Feynman machines, von Neumann replicators, etc.) should enable direct monitoring, decoding and interfacing between biological and technological information devices. This in turn could result in important biomedical applications and perhaps a merger of mind and machine: Ultimate Computing.

  8. Computer vision technology in log volume inspection

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    Log volume inspection is very important in forestry research and paper making engineering. This paper proposed a novel approach based on computer vision technology to cope with log volume inspection. The needed hardware system was analyzed and the details of the inspection algorithms were given. A fuzzy entropy based on image enhancement algorithm was presented for enhancing the image of the cross-section of log. In many practical applications the cross-section is often partially invisible, and this is the major obstacle for correct inspection. To solve this problem, a robust Hausdorff distance method was proposed to recover the whole cross-section. Experiment results showed that this method was efficient.

  9. Compiler Technology for Parallel Scientific Computation

    Directory of Open Access Journals (Sweden)

    Can Özturan

    1994-01-01

    Full Text Available There is a need for compiler technology that, given the source program, will generate efficient parallel codes for different architectures with minimal user involvement. Parallel computation is becoming indispensable in solving large-scale problems in science and engineering. Yet, the use of parallel computation is limited by the high costs of developing the needed software. To overcome this difficulty we advocate a comprehensive approach to the development of scalable architecture-independent software for scientific computation based on our experience with equational programming language (EPL. Our approach is based on a program decomposition, parallel code synthesis, and run-time support for parallel scientific computation. The program decomposition is guided by the source program annotations provided by the user. The synthesis of parallel code is based on configurations that describe the overall computation as a set of interacting components. Run-time support is provided by the compiler-generated code that redistributes computation and data during object program execution. The generated parallel code is optimized using techniques of data alignment, operator placement, wavefront determination, and memory optimization. In this article we discuss annotations, configurations, parallel code generation, and run-time support suitable for parallel programs written in the functional parallel programming language EPL and in Fortran.

    Energy management systems were defined and reviewed, focusing on how the development in computer technology has impacted on the development of energy management systems. It was shown that the rise of micro-computer systems made it possible to create a tool that is well adapted to the urgent need for optimizing electromechanical systems to meet energy reduction criteria while still maintaining occupant comfort. Two case studies were cited to show the kind of savings realized by the different energy management systems installed. Besides managing energy, energy management systems can also help in detecting certain operating failures or irregularities in equipment configurations, monitoring and measuring energy consumption, as well as performing such peripherally related functions as gathering data about operating and space temperatures.

    We have entered the age of ''terascale'' scientific computing. Processors and system architecture both continue to evolve; hundred-teraFLOP computers are expected in the next few years, and petaFLOP computers toward the end of this decade are conceivable. This ever-increasing power to solve previously intractable numerical problems benefits almost every field of science and engineering and is revolutionizing some of them, notably including accelerator physics and technology. At existing accelerators, it will help us optimize performance, expand operational parameter envelopes, and increase reliability. Design decisions for next-generation machines will be informed by unprecedented comprehensive and accurate modeling, as well as computer-aided engineering; all this will increase the likelihood that even their most advanced subsystems can be commissioned on time, within budget, and up to specifications. Advanced computing is also vital to developing new means of acceleration and exploring the behavior of beams under extreme conditions. With continued progress it will someday become reasonable to speak of a complete numerical model of all phenomena important to a particular accelerator.

    Light field imaging is capable of capturing dense multi-view 2D images in one snapshot, which record both intensity values and directions of rays simultaneously. As an emerging 3D device, the light field camera has been widely used in digital refocusing, depth estimation, stereoscopic display, etc. Traditional multi-view stereo (MVS) methods only perform well on strongly texture surfaces, but the depth map contains numerous holes and large ambiguities on textureless or low-textured regions. In this paper, we exploit the light field imaging technology on 3D face modeling in computer vision. Based on a 3D morphable model, we estimate the pose parameters from facial feature points. Then the depth map is estimated through the epipolar plane images (EPIs) method. At last, the high quality 3D face model is exactly recovered via the fusing strategy. We evaluate the effectiveness and robustness on face images captured by a light field camera with different poses.

    Shi, Jing; Xu, Xiangjun; Wang, Jialai; Li, Gong

    2010-09-01

    In this paper, a new approach for efficient damage detection in engineering structures is introduced. The key concept is to use the mature computer vision technology to capture the static deformation profile of a structure, and then employ profile analysis methods to detect the locations of the damages. By combining with wireless communication techniques, the proposed approach can provide an effective and economical solution for remote monitoring of structure health. Moreover, a preliminary experiment is conducted to verify the proposed concept. A commercial computer vision camera is used to capture the static deformation profiles of cracked cantilever beams under loading. The profiles are then processed to reveal the existence and location of the irregularities on the deformation profiles by applying fractal dimension, wavelet transform and roughness methods, respectively. The proposed concept is validated on both one-crack and two-crack cantilever beam-type specimens. It is also shown that all three methods can produce satisfactory results based on the profiles provided by the vision camera. In addition, the profile quality is the determining factor for the noise level in resultant detection signal.

    Today, computer technology is within the reach of practically any industrial corporation regardless of product size. This manual highlights a few of the many applications of computers in the process industry and provides the technical reader with a basic understanding of computer technology, terminology, and the interactions among the various elements of a process computer system. The manual has been organized to separate process applications and economics from computer technology. Chapter 1 introduces the present status of process computer technology and describes the four major applications - monitoring, analysis, control, and optimization. The basic components of a process computer system also are defined. Energy-saving applications in the four major categories defined in Chapter 1 are discussed in Chapter 2. The economics of process computer systems is the topic of Chapter 3, where the historical trend of process computer system costs is presented. Evaluating a process for the possible implementation of a computer system requires a basic understanding of computer technology as well as familiarity with the potential applications; Chapter 4 provides enough technical information for an evaluation. Computer and associated peripheral costs and the logical sequence of steps in the development of a microprocessor-based process control system are covered in Chapter 5.

    Martínez-Mateo, Jesús; Pérez-Rey, David

    2010-01-01

    Computer literacy is not negotiable for any professional in an increasingly computerised environment. Educational institutions should be equipped to provide this new basic training for modern life. Accordingly, computer labs are an essential medium for education in almost any field. Computer labs are one of the most popular IT infrastructures for technical training in primary and secondary schools, universities and other educational institutions all over the world. Unfortunately, a computer lab is expensive, in terms of both initial purchase and annual maintenance costs, and especially when we want to run the latest software. Hence, research efforts addressing computer lab efficiency, performance or cost reduction would have a worldwide repercussion. In response to this concern, this paper presents a survey on thin client technology for computer labs in educational environments. Besides setting out the advantages and drawbacks of this technology, we aim to refute false prejudices against thin clients, identif...

  9. Enabling Computational Technologies for Terascale Scientific Simulations

    Energy Technology Data Exchange (ETDEWEB)

    Ashby, S.F.

    2000-08-24

    We develop scalable algorithms and object-oriented code frameworks for terascale scientific simulations on massively parallel processors (MPPs). Our research in multigrid-based linear solvers and adaptive mesh refinement enables Laboratory programs to use MPPs to explore important physical phenomena. For example, our research aids stockpile stewardship by making practical detailed 3D simulations of radiation transport. The need to solve large linear systems arises in many applications, including radiation transport, structural dynamics, combustion, and flow in porous media. These systems result from discretizations of partial differential equations on computational meshes. Our first research objective is to develop multigrid preconditioned iterative methods for such problems and to demonstrate their scalability on MPPs. Scalability describes how total computational work grows with problem size; it measures how effectively additional resources can help solve increasingly larger problems. Many factors contribute to scalability: computer architecture, parallel implementation, and choice of algorithm. Scalable algorithms have been shown to decrease simulation times by several orders of magnitude.

    Full Text Available The thirty-five-year period of computer terminology has to be considered the initial stage of its evolution where synonymy and variability are characteristic features, which are usually determined by both extra-linguistic and linguistic factors. The choice of borrowed or Lithuanian terms is often determined by the relationship between borrowed and Lithuanian terms. The first stage of the newest dictionaries of computer terms approbated by the Commission of the Lithuanian Language shows that the terminology of the mentioned field is being systematized and normalized. However, the ratio between Lithuanian and borrowed terms is not fully acceptable yet, and it is partially determined by disagreement among specialists on the status of synonymous terms and the choice of them.

    There is undoubtedly a commitment in the oil refining industry to computerise wherever possible, and to develop advanced mathematical modelling techniques to improved profitability. However, many oil refiners are now asking themselves whether computer solutions are a cost, or are truly a benefit to their organisation. Problems have been caused by distributed computing running out of control in many organisations. This has been partly brought to reign recently, by advanced networking of PCs along with mainframe facilities, and development of management information systems with common data bases for all users to build their applications on. Implementation of information technology strategies helped many refiners to plan the way ahead for the future. The use of computers across the refining sector in the current marketplace is reviewed. The conclusion drawn is that although computer technology is a cost it can also be ranked as a significant benefit and success in the refining industry at present. (author).

    Users with disabilities interact with Personal Computers (PCs) using Assistive Technology (AT) software solutions. Such applications run on a PC that a person with a disability commonly uses. However the configuration of AT applications is not trivial at all, especially whenever the user needs to work on a PC that does not allow him/her to rely on his / her AT tools (e.g., at work, at university, in an Internet point). In this paper, we discuss how cloud computing provides a valid technological solution to enhance such a scenario.With the emergence of cloud computing, many applications are executed on top of virtual machines (VMs). Virtualization allows us to achieve a software implementation of a real computer able to execute a standard operating system and any kind of application. In this paper we propose to build personalized VMs running AT programs and settings. By using the remote desktop technology, our solution enables users to control their customized virtual desktop environment by means of an HTML5-based web interface running on any computer equipped with a browser, whenever they are.

    With the development of information technology, the fire safety assessment of whole structure or region based on the computer simulation has become a hot topic. However, traditionally, the concemed studies are performed separately for different objectives and difficult to perform an overall evaluation. A new multi-dimensional integration model and methodology for fire safety assessment were presented and two newly developed integrated systems were introduced to demonstrate the function of integration simulation technology in this paper. The first one is the analysis on the fire-resistant behaviors of whole structure under real fire loads. The second one is the study on fire evaluation and emergency rescue of campus based on geography information technology (GIS). Some practical examples are presented to illuminate the advan-tages of computer integration technology on fire safety assessment and emphasize some problems in the simulation. The results show that the multi-dimensional integration model offers a new way and platform for the integrating fire safety assessment of whole structure or region, and the integrated software developed is the useful engineering tools for cost-saving and safe design.

    2014-05-15

    In this research, we developed a plan for experimental validation of one of the computer models developed for ER process modeling, i. e., the ERAD code. Several candidate surrogate materials are selected for the experiment considering the chemical and physical properties. Molten salt-based pyroprocessing technology is being examined internationally as an alternative to treat spent nuclear fuel over aqueous technology. The central process in pyroprocessing is electrorefining(ER) which separates uranium from transuranic elements and fission products present in spent nuclear fuel. ER is a widely used process in the minerals industry to purify impure metals. Studies of ER by using actual spent nuclear fuel materials are problematic for both technical and political reasons. Therefore, the initial effort for ER process optimization is made by using computer models. A number of models have been developed for this purpose. But as validation of these models is incomplete and often times problematic, the simulation results from these models are inherently uncertain.

    Full Text Available Jewelry production is a process of precious raw materials and low losses in processing. The traditional manual mode is unable to meet the needs of enterprises in reality, while the involvement of computer technology can just solve this practical problem. At present, the problem of restricting the application for computer in jewelry production is mainly a failure to find a production model that can serve the whole industry chain with the computer as the core of production. This paper designs a “synchronous and diversified” production model with “computer aided design technology” and “rapid prototyping technology” as the core, and tests with actual production cases, and achieves certain results, which are forward-looking and advanced.

    Desktop models are those models used by analysts with varied backgrounds, for performing, for example, air quality assessment and emergency response activities. These models must be robust, well documented, have minimal and well controlled user inputs, and have clear outputs. Existing coarse-grained parallel computers can provide significant increases in computation speed in desktop atmospheric dispersion modeling without considerable increases in hardware cost. This increased speed will allow for significant improvements to be made in the scientific foundations of these applied models, in the form of more advanced diffusion schemes and better representation of the wind and turbulence fields. This is especially attractive for emergency response applications where speed and accuracy are of utmost importance. This paper describes one particular application of coarse-grained parallel computer technology to a desktop complex terrain atmospheric dispersion modeling system. By comparing performance characteristics of the coarse-grained parallel version of the model with the single-processor version, we will demonstrate that applying coarse-grained parallel computer technology to desktop atmospheric dispersion modeling systems will allow us to address critical issues facing future requirements of this class of dispersion models.

    Background The National Library of Medicine's National Center for Biotechnology Information offers mini-courses which entail applying concepts in biochemistry and genetics to search genomics databases and other information sources. They are highly interactive and involve use of 3D molecular visualization software that can be computationally taxing. Methods Methods were devised to offer the courses at a distance so as to provide as much functionality of a computer lab as possible, the venue where they are normally taught. The methods, which can be employed with varied videoconferencing technology and desktop sharing software, were used to deliver mini-courses at a distance in pilot applications where students could see demonstrations by the instructor and the instructor could observe and interact with students working at their remote desktops. Results Student ratings of the learning experience and comments to open ended questions were similar to those when the courses are offered face to face. The real time interaction and the instructor's ability to access student desktops from a distance in order to provide individual assistance and feedback were considered invaluable. Conclusion The technologies and methods mimic much of the functionality of computer labs and may be usefully applied in any context where content changes frequently, training needs to be offered on complex computer applications at a distance in real time, and where it is necessary for the instructor to monitor students as they work.

    The evolution of computer networks has experienced several major steps, and research focus of each step has been kept changing and evolving, from ARPANET to OSI/RM, then HSN (high speed network) and HPN (high performance network). During the evolution, computer networks represented by Internet have made great progress and gained unprecedented success. However, with the appearance and intensification of tussle, along with the three difficult problems (service customizing, resource control and user management) of modern network, it is found that traditional Internet and its architecture no longer meet the requirements of next generation network. Therefore, it is the next generation network that current Internet must evolve to. With the mindset of achieving valuable guidance for research on next generation network, this paper firstly analyzes some dilemmas facing current Internet and its architecture, and then surveys some recent influential research work and progresses in computer networks and related areas, including new generation network architecture, network resource control technologies, network management and security, distributed computing and middleware,wireless/mobile network, new generation network services and applications, and foundational theories on network modeling.Finally, this paper concludes that within the research on next generation network, more attention should be paid to the high availability network and corresponding architecture, key theories and supporting technologies.

    Much of the polymer composites industry is built around the thermochemical conversion of raw material into useful composites. The raw materials (molding compound, prepreg) often are made up of thermosetting resins and small fibers or particles. While this conversion can follow a large number of paths, only a few paths are efficient, economical and lead to desirable composite properties. Processing instrument (P/I) technology enables a computer to sense and interpret changes taking place during the cure of prepreg or molding compound. P/I technology has been used to make estimates of gel time and cure time, thermal diffusivity measurements and transition temperature measurements. Control and sensing software is comparatively straightforward. The interpretation of results with appropriate software is under development.

    The purpose of this scoping review of literature is to explore the types of computer-based systems used for self-management of chronic disease, the goals and success of these systems, the value added by technology integration and the target audience for these systems. Technology is changing the way health care is provided and the way that individuals manage their health. Individuals with chronic diseases are now able to use computer-based systems to self-manage their health. These systems have the ability to remind users of daily activities, and to help them recognise when symptoms are worsening and intervention is indicated. However, there are many questions about the types of systems available, the goals of these systems and the success with which individuals with chronic illness are using them. This is a scoping review in which the Cumulative Index of Nursing and Allied Health Literature, PubMed and IEEE Xplore databases were searched. A total of 303 articles were reviewed, 89 articles were read in-depth and 30 were included in the scoping review. The Substitution, Augmentation, Modification, Redefinition model was used to evaluate the value added by the technology integration. Research on technology for self-management was conducted in 13 countries. Data analysis identified five kinds of platforms on which the systems were based, some systems were focused on a specific disease management processes, others were not. For individuals to effectively use systems to maintain maximum wellness, the systems must have a strong component of self-management and provide the user with meaningful information regarding their health states. Clinicians should choose systems for their clients based on the design, components and goals of the systems. © 2016 John Wiley & Sons Ltd.

    Crespin, Timothy R; Austin, James T

    2002-08-01

    This article reviews computer applications developed and utilized by industrial-organizational (I-O) psychologists, both in practice and in research. A primary emphasis is on applications developed for Internet usage, because this "network of networks" changes the way I-O psychologists work. The review focuses on traditional and emerging topics in I-O psychology. The first topic involves information technology applications in measurement, defined broadly across levels of analysis (persons, groups, organizations) and domains (abilities, personality, attitudes). Discussion then focuses on individual learning at work, both in formal training and in coping with continual automation of work. A section on job analysis follows, illustrating the role of computers and the Internet in studying jobs. Shifting focus to the group level of analysis, we briefly review how information technology is being used to understand and support cooperative work. Finally, special emphasis is given to the emerging "third discipline" in I-O psychology research-computational modeling of behavioral events in organizations. Throughout this review, themes of innovation and dissemination underlie a continuum between research and practice. The review concludes by setting a framework for I-O psychology in a computerized and networked world.

  12. Using Computer Technology to Foster Learning for Understanding

    Directory of Open Access Journals (Sweden)

    Elaine Van Melle

    2009-12-01

    Full Text Available The literature shows that students typically use either a surface approach to learning, in which the emphasis is on memorization of facts, or a deep approach to learning, in which learning for understanding is the primary focus. This paper describes how computer technology, specifically the use of a multimedia CD-ROM, was integrated into a microbiology curriculum as part of the transition from focusing on facts to fostering learning for understanding. Evaluation of the changes in approaches to learning over the course of the term showed a statistically significant shift in a deep approach to learning, as measured by the Study Process Questionnaire. Additional data collected showed that the use of computer technology supported this shift by providing students with the opportunity to apply what they had learned in class to order tests and interpret the test results in relation to specific patient-focused case studies. The extent of the impact, however, varied among different groups of students in the class. For example, students who were recent high school graduates did not show a statistically significant increase in deep learning scores over the course of the term and did not perform as well in the course. The results also showed that a surface approach to learning was an important aspect of learning for understanding, although only those students who were able to combine a surface with a deep approach to learning were successfully able to learn for understanding. Implications of this finding for the future use of computer technology and learning for understanding are considered.

    2015-02-01

    This paper provides an analysis of perspectives from different stakeholders on the state-of-the-art of BCI. Three barriers for technology transfer of BCIs as access technologies are identified. First, BCIs are developed with a narrow focus on creating a reliable technology, while a broader focus on creating a usable technology is needed. Second, the potential target group, which could benefit from BCIs as access technologies is expected to be very small. Development costs are therefore high, while reimbursements are expected to be low, which challenges the commercial viability. Third, potential target users should be much more included in the design process of BCIs to ensure that the end-products meet technical, ethical, legal and social requirements. These three issues need to be urgently addressed so that target users may benefit from this promising technology.

    High performance computing environments are often used for a wide variety of workloads ranging from simulation, data transformation and analysis, and complex workflows to name just a few. These systems may process data for a variety of users, often requiring strong separation between job allocations. There are many challenges to establishing these secure enclaves within the shared infrastructure of high-performance computing (HPC) environments. The isolation mechanisms in the system software are the basic building blocks for enabling secure compute enclaves. There are a variety of approaches and the focus of this report is to review the different virtualization technologies that facilitate the creation of secure compute enclaves. The report reviews current operating system (OS) protection mechanisms and modern virtualization technologies to better understand the performance/isolation properties. We also examine the feasibility of running ``virtualized'' computing resources as non-privileged users, and providing controlled administrative permissions for standard users running within a virtualized context. Our examination includes technologies such as Linux containers (LXC [32], Docker [15]) and full virtualization (KVM [26], Xen [5]). We categorize these different approaches to virtualization into two broad groups: OS-level virtualization and system-level virtualization. The OS-level virtualization uses containers to allow a single OS kernel to be partitioned to create Virtual Environments (VE), e.g., LXC. The resources within the host's kernel are only virtualized in the sense of separate namespaces. In contrast, system-level virtualization uses hypervisors to manage multiple OS kernels and virtualize the physical resources (hardware) to create Virtual Machines (VM), e.g., Xen, KVM. This terminology of VE and VM, detailed in Section 2, is used throughout the report to distinguish between the two different approaches to providing virtualized execution

    Full Text Available For Canada to compete effectively in the digital world, beginning teachers need to play an important role in integrating computer technology into the curriculum. Equipment and connectivity do not guarantee successful or productive use of computers in the classroom, but the combination of the teaching style and technology use has the potential to change education. In this research, the computer self-efficacy beliefs of 210 preservice teachers after their first practice teaching placements were examined. First, the quantitative component of the study involved the use of Computer User Self-Efficacy (CUSE scale where students’ previous undergraduate degree, licensure area, experience and familiarity with software packages were found to have statistically significant effects on computer self-efficacy. Second, the qualitative data indicated that society and school were the most positive factors that influenced preservice teachers’ attitudes towards computers, while the family had the highest percentage of negative influence. Findings reveal that although preservice teachers had completed only two months of the program, those with higher CUSE scores were more ready to integrate computers into their lessons than those with lower scores. Résumé: Pour que le Canada puisse entrer en compétition dans le monde numérique, les nouveaux enseignants devront jouer un rôle important d’intégration des technologies informatiques dans le curriculum. Les équipements et la connectivité ne garantissent pas une utilisation gagnante ou productive de l’ordinateur en salle de classe, mais la combinaison de styles d’enseignement et d’usages de la technologie a le potentiel de changer l’éducation. Dans cette étude, les croyances d’auto-efficacité à l’ordinateur de 210 futurs enseignants après leur première affectation ont été examinées. Premièrement, la partie quantitative de l’étude impliquait l’utilisation de l’échelle du Computer

    2013-05-01

    Scalability is one of the main challenges of trapped ion based quantum computation, mainly limited by the lack of enabling technologies needed to trap, manipulate and process the increasing number of qubits. Microelectromechanical systems (MEMS) technology allows one to design movable micromirrors to focus laser beams on individual ions in a chain and steer the focal point in two dimensions. Our current MEMS system is designed to steer 355 nm pulsed laser beams to carry out logic gates on a chain of Yb ions with a waist of 1.5 μm across a 20 μm range. In order to read the state of the qubit chain we developed a 32-channel PMT with a custom read-out circuit operating near the thermal noise limit of the readout amplifier which increases state detection fidelity. We also developed a set of digital to analog converters (DACs) used to supply analog DC voltages to the electrodes of an ion trap. We designed asynchronous DACs to avoid added noise injection at the update rate commonly found in synchronous DACs. Effective noise filtering is expected to reduce the heating rate of a surface trap, thus improving multi-qubit logic gate fidelities. Our DAC system features 96 channels and an integrated FPGA that allows the system to be controlled in real time. This work was supported by IARPA/ARO.

    1992-01-01

    Magnetohydrodynamic (MHD) power generation is a clean coal technology because of its higher thermal efficiency and lower pollutant emission. Argonne National Laboratory used a comprehensive integral combustion computer code to aid the development of a TRW's second stage combustor for MHD power generation. The integral combustion code is a computer code for two-phase, two-dimensional, steady state, turbulent, and reacting flows, based on mass, momentum, and energy conservation laws for multiple gas species and solid particles of variable sizes. In the MHD second stage combustor, opposed jets of oxidizer are injected into a confined cross-stream coal gas flow laden with seed particles. The performance of the downstream MHD power generation channel depends mainly on the degree and the uniformity of gas ionization, which, in turn, depends on the uniformity of temperature and seed vapor distributions leaving the combustor. The simulation provides in-depth information of flow, combustion, and heat transfer patterns in the combustor, which is used to predict ranges of combustor operating conditions for optimum performance of the MHD system.

The integral combustion code is a computer code for two-phase, two-dimensional, steady state, turbulent, and reacting flows, based on mass, momentum, and energy conservation laws for multiple gas species and solid particles of variable sizes. In the MHD second stage combustor, opposed jets of oxidizer are injected into a confined cross-stream coal gas flow laden with seed particles. The performance of the downstream MHD power generation channel depends mainly on the degree and the uniformity of gas ionization, which, in turn, depends on the uniformity of temperature and seed vapor distributions leaving the combustor. The simulation provides in-depth information of flow, combustion, and heat transfer patterns in the combustor, which is used to predict ranges of combustor operating conditions for optimum performance of the MHD system.

    applicable to commercial production processes and applications. Computer vision will play a critical role in the new agile production environment for automation of processes such as inspection, assembly, welding, material dispensing and other process control tasks. Although there are many academic and commercial solutions that have been developed, none have had widespread adoption considering the huge potential number of applications that could benefit from this technology. The reason for this slow adoption is that the advantages of computer vision for automation can be a double-edged sword. The benefits can be lost if the vision system requires an inordinate amount of time for reprogramming by a skilled operator to account for different parts, changes in lighting conditions, background clutter, changes in optics, etc. Commercially available solutions typically require an operator to manually program the vision system with features used for the recognition. In a recent survey, we asked a number of commercial manufacturers and machine vision companies the question, 'What prevents machine vision systems from being more useful in factories?' The number one (and unanimous) response was that vision systems require too much skill to set up and program to be cost effective.

    Background Efforts to achieve population-wide increases in walking and similar moderate-intensity physical activities potentially can be enhanced through relevant applications of state-of-the-art interactive communication technologies. Yet few systematic efforts to evaluate the efficacy of hand-held computers and similar devices for enhancing physical activity levels have occurred. The purpose of this first-generation study was to evaluate the efficacy of a hand-held computer (i.e., personal digital assistant [PDA]) for increasing moderate intensity or more vigorous (MOD+) physical activity levels over 8 weeks in mid-life and older adults relative to a standard information control arm. Design Randomized, controlled 8-week experiment. Data were collected in 2005 and analyzed in 2006-2007. Setting/Participants Community-based study of 37 healthy, initially underactive adults aged 50 years and older who were randomized and completed the 8-week study (intervention=19, control=18). Intervention Participants received an instructional session and a PDA programmed to monitor their physical activity levels twice per day and provide daily and weekly individualized feedback, goal setting, and support. Controls received standard, age-appropriate written physical activity educational materials. Main Outcome Measure Physical activity was assessed via the Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire at baseline and 8 weeks. Results Relative to controls, intervention participants reported significantly greater 8-week mean estimated caloric expenditure levels and minutes per week in MOD+ activity (p<0.04). Satisfaction with the PDA was reasonably high in this largely PDA-naive sample. Conclusions Results from this first-generation study indicate that hand-held computers may be effective tools for increasing initial physical activity levels among underactive adults. PMID:18201644

    1995-01-01

    Advances in computer technology provide a wide range of applications which are revolutionizing the practice of medicine. The development of new software for the office creates a web of communication among physicians, staff members, health care facilities and associated agencies. This provides the physician with the prospect of a paperless office. At the other end of the spectrum, the development of 3D work stations and software based on computational chemistry permits visualization of protein molecules involved in disease. Computer assisted molecular modeling has been used to construct working 3D models of lens alpha-crystallin. The 3D structure of alpha-crystallin is basic to our understanding of the molecular mechanisms involved in lens fiber cell maturation, stabilization of the inner nuclear region, the maintenance of lens transparency and cataractogenesis. The major component of the high molecular weight aggregates that occur during cataractogenesis is alpha-crystallin subunits. Subunits of alpha-crystallin occur in other tissues of the body. In the central nervous system accumulation of these subunits in the form of dense inclusion bodies occurs in pathological conditions such as Alzheimer's disease, Huntington's disease, multiple sclerosis and toxoplasmosis (Iwaki, Wisniewski et al., 1992), as well as neoplasms of astrocyte origin (Iwaki, Iwaki, et al., 1991). Also cardiac ischemia is associated with an increased alpha B synthesis (Chiesi, Longoni et al., 1990). On a more global level, the molecular structure of alpha-crystallin may provide information pertaining to the function of small heat shock proteins, hsp, in maintaining cell stability under the stress of disease.

    2017-08-01

    With the development of computer technology, computer graphics technology has been widely used. Especially, the success of object-oriented technology and multimedia technology promotes the development of graphics technology in the computer software system. Therefore, the computer graphics theory and application technology have become an important topic in the field of computer, while the computer graphics technology becomes more and more extensive in various fields of application. In recent years, with the development of social economy, especially the rapid development of information technology, the traditional way of communication resource management cannot effectively meet the needs of resource management. In this case, the current communication resource management is still using the original management tools and management methods, resource management equipment management and maintenance, which brought a lot of problems. It is very difficult for non-professionals to understand the equipment and the situation in communication resource management. Resource utilization is relatively low, and managers cannot quickly and accurately understand the resource conditions. Aimed at the above problems, this paper proposes to introduce computer graphics technology into the communication resource management. The introduction of computer graphics not only makes communication resource management more vivid, but also reduces the cost of resource management and improves work efficiency.

    Objective structured clinical examinations (OSCEs) are multistationed clinical examinations that have been shown to be effective in testing students' ability to integrate the knowledge, skills, and attitudes acquired during their preclinical and clinical training and experiences. The original OSCE for the third-year Preventive Dentistry course at Baylor College of Dentistry was based on the traditional format consisting of four sections of twelve stations with a group of twelve students rotating through each of the sections simultaneously. This arrangement allowed for examination of one-half of the class. The other half of the class took the exam on an alternate date. To reduce the disruption caused by the students' moving from station to station and to allow for examination of the entire class in one setting, the traditional concept was modified using computer technology, and the twelve stations "moved" via a PowerPoint presentation while students remained stationary. Questions on both exams provided a means for testing data interpretation, diagnostic skills, and, to some extent, interpersonal skills. The overall atmosphere during the computer-based examination was less chaotic. Each student received identical instructions, explanations, and time allotments to respond to the information presented. The ratio of faculty to students required to monitor the exam was less than required for the traditional format. Additionally, since there was no need to allow time for student transition, the total time required to administer the exam was reduced. Thus, objective assessment of the entire class was accomplished using fewer faculty members and less class time and with less disruption for the students.

    ATLAS event data processing requires access to non-event data (detector conditions, calibrations, etc.) stored in relational databases. The database-resident data are crucial for the event data reconstruction processing steps and often required for user analysis. A main focus of ATLAS database operations is on the worldwide distribution of the Conditions DB data, which are necessary for every ATLAS data processing job. Since Conditions DB access is critical for operations with real data, we have developed the system where a different technology can be used as a redundant backup. Redundant database operations infrastructure fully satisfies the requirements of ATLAS reprocessing, which has been proven on a scale of one billion database queries during two reprocessing campaigns of 0.5 PB of single-beam and cosmics data on the Grid. To collect experience and provide input for a best choice of technologies, several promising options for efficient database access in user analysis were evaluated successfully. We pre...

    This study examines the attitudes of Saudi Arabian high school students toward the use of computer technologies in learning English. The study also discusses the possible barriers that affect and limit the actual usage of computers. Quantitative approach is applied in this research, which involved 30 Saudi Arabia students of a high school in Kuala Lumpur, Malaysia. The respondents comprised 15 males and 15 females with ages between 16 years and 18 years. Two instruments, namely, Scale of Attitude toward Computer Technologies (SACT) and Barriers affecting Students' Attitudes and Use (BSAU) were used to collect data. The Technology Acceptance Model (TAM) of Davis (1989) was utilized. The analysis of the study revealed gender differences in attitudes toward the use of computer technologies in learning English. Female students showed high and positive attitudes towards the use of computer technologies in learning English than males. Both male and female participants demonstrated high and positive perception of Usefulness and perceived Ease of Use of computer technologies in learning English. Three barriers that affected and limited the use of computer technologies in learning English were identified by the participants. These barriers are skill, equipment, and motivation. Among these barriers, skill had the highest effect, whereas motivation showed the least effect.

    This paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher-students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants' instruction with computer technology was ( Teacher) initiation-( Student and Teacher) response sequences-( Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers' learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers' own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content.

    Thank you for your interest in the activities of the Lawrence Livermore National Laboratory Computation Directorate. This collection of articles from the Laboratory's Science & Technology Review highlights the most significant computational projects, achievements, and contributions during 2002. In 2002, LLNL marked the 50th anniversary of its founding. Scientific advancement in support of our national security mission has always been the core of the Laboratory. So that researchers could better under and predict complex physical phenomena, the Laboratory has pushed the limits of the largest, fastest, most powerful computers in the world. In the late 1950's, Edward Teller--one of the LLNL founders--proposed that the Laboratory commission a Livermore Advanced Research Computer (LARC) built to Livermore's specifications. He tells the story of being in Washington, DC, when John Von Neumann asked to talk about the LARC. He thought Teller wanted too much memory in the machine. (The specifications called for 20-30,000 words.) Teller was too smart to argue with him. Later Teller invited Von Neumann to the Laboratory and showed him one of the design codes being prepared for the LARC. He asked Von Neumann for suggestions on fitting the code into 10,000 words of memory, and flattered him about ''Labbies'' not being smart enough to figure it out. Von Neumann dropped his objections, and the LARC arrived with 30,000 words of memory. Memory, and how close memory is to the processor, is still of interest to us today. Livermore's first supercomputer was the Remington-Rand Univac-1. It had 5600 vacuum tubes and was 2 meters wide by 4 meters long. This machine was commonly referred to as a 1 KFlop machine [E+3]. Skip ahead 50 years. The ASCI White machine at the Laboratory today, produced by IBM, is rated at a peak performance of 12.3 TFlops or E+13. We've improved computer processing power by 10 orders of magnitude in 50 years, and I do

    Most parts of present computer systems are made of volatile devices, and the power to supply them to avoid information loss causes huge energy losses. We can eliminate this meaningless energy loss by utilizing the non-volatile function of advanced spin-transfer torque magnetoresistive random-access memory (STT-MRAM) technology and create a new type of computer, i.e., normally off computers. Critical tasks to achieve normally off computers are implementations of STT-MRAM technologies in the main memory and low-level cache memories. STT-MRAM technology for applications to the main memory has been successfully developed by using perpendicular STT-MRAMs, and faster STT-MRAM technologies for applications to the cache memory are now being developed. The present status of STT-MRAMs and challenges that remain for normally off computers are discussed.

  14. Science and computer-based technologies: attitudes of secondary science teachers

    Science.gov (United States)

    Ng, Wan; Gunstone, Richard

    2003-02-01

    As is the case with most developed countries, pressures from various sectors of society have seen computers make a big presence in Australian education systems in the last decade. In the state of Victoria, integrating learning technology (LT) into all key learning areas of every school's curriculum has been a priority policy of governments. Over the last 8-10 years, large amounts of money have been provided to set schools up with computers and associated technologies. In the area of science, a range of LT resources is available for use in the teaching and learning processes in the classroom. However, there has been limited evaluation into teachers' attitudes towards, and types of, methodology and effectiveness of usage of computer-based technologies in knowledge construction. Using both quantitative and qualitative methods, a study aimed at identifying science teachers' opinions and practices with the use of computer-based technologies in their teaching has been carried out in Victorian government schools. The focus of this paper is on the attitudes of these science teachers towards the use of computer-based technologies in their teaching. The study showed that most teachers have embraced the introduction of these technologies into the school structure well and are generally positive about their potential in the classroom. However, their use in the classrooms is infrequent and often on an ad hoc basis. A range of obstacles preventing the use of these technologies are identified and discussed in this paper.

  10. Application of modern computer technology to EPRI (Electric Power Research Institute) nuclear computer programs: Final report

    Energy Technology Data Exchange (ETDEWEB)

    Feinauer, L.R.

    1989-08-01

    Many of the nuclear analysis programs in use today were designed and developed well over a decade ago. Within this time frame, tremendous changes in hardware and software technologies have made it necessary to revise and/or restructure most of the analysis programs to take advantage of these changes. As computer programs mature from the development phase to being production programs, program maintenance and portability become very important issues. The maintenance costs associated with a particular computer program can generally be expected to exceed the total development costs by as much as a factor of two. Many of the problems associated with high maintenance costs can be traced back to either poorly designed coding structure, or ''quick fix'' modifications which do not preserve the original coding structure. The lack of standardization between hardware designs presents an obstacle to the software designer in providing 100% portable coding; however, conformance to certain guidelines can ensure portability between a wide variety of machines and operating systems. This report presents guidelines for upgrading EPRI nuclear computer programs to conform to current programming standards while maintaining flexibility for accommodating future hardware and software design trends. Guidelines for development of new computer programs are also presented. 22 refs., 10 figs.

    Assistive technology for computer access can be used to facilitate people with a spinal cord injury to utilize mainstream computer applications, thereby enabling participation in a variety of meaningful occupations. The aim of this study was to gain an understanding of the experiences of clients with tetraplegia trialing assistive technologies for computer access during different stages in a public rehabilitation service. In order to explore the experiences of clients with tetraplegia trialing assistive technologies for computer use, qualitative methodology was selected. Data were collected from seven participants using semi-structured interviews, which were audio-taped, transcribed and analyzed thematically. Three main themes were identified. These were: getting back into life, assisting in adjusting to injury and learning new skills. The findings from this study demonstrated that people with tetraplegia can be assisted to return to previous life roles or engage in new roles, through developing skills in the use of assistive technology for computer access. Being able to use computers for meaningful activities contributed to the participants gaining an enhanced sense of self-efficacy, and thereby quality of life. Implications for Rehabilitation Findings from this pilot study indicate that people with tetraplegia can be assisted to return to previous life roles, and develop new roles that have meaning to them through the use of assistive technologies for computer use. Being able to use the internet to socialize, and complete daily tasks, contributed to the participants gaining a sense of control over their lives. Early introduction to assistive technology is important to ensure sufficient time for newly injured people to feel comfortable enough with the assistive technology to use the computers productively by the time of discharge. Further research into this important and expanding area is indicated.

    1995-01-01

    The objective of this summer's work was to attempt to enhance Technology Application Group (TAG) ability to measure the outcomes of its efforts to transfer NASA technology. By reviewing existing literature, by explaining the economic principles involved in evaluating the economic impact of technology transfer, and by investigating the LaRC processes our William & Mary team has been able to lead this important discussion. In reviewing the existing literature, we identified many of the metrics that are currently being used in the area of technology transfer. Learning about the LaRC technology transfer processes and the metrics currently used to track the transfer process enabled us to compare other R&D facilities to LaRC. We discuss and diagram impacts of technology transfer in the short run and the long run. Significantly, it serves as the basis for analysis and provides guidance in thinking about what the measurement objectives ought to be. By focusing on the SBIR Program, valuable information regarding the strengths and weaknesses of this LaRC program are to be gained. A survey was developed to ask probing questions regarding SBIR contractors' experience with the program. Specifically we are interested in finding out whether the SBIR Program is accomplishing its mission, if the SBIR companies are providing the needed innovations specified by NASA and to what extent those innovations have led to commercial success. We also developed a survey to ask COTR's, who are NASA employees acting as technical advisors to the SBIR contractors, the same type of questions, evaluating the successes and problems with the SBIR Program as they see it. This survey was developed to be implemented interactively on computer. It is our hope that the statistical and econometric studies that can be done on the data collected from all of these sources will provide insight regarding the direction to take in developing systematic evaluations of programs like the SBIR Program so that they can

    The Critical Issues Forum (CIF) funded by the US Department of Energy is a collaborative effort between the Science Education Team of Los Alamos National Laboratory (LANL) and New Mexico high schools to improve science education throughout the state of New Mexico as well as nationally. By creating an education relationship between the LANL with its unique scientific resources and New Mexico high schools, students and teachers participate in programs that increase not only their science content knowledge but also their critical thinking and problem-solving skills. The CIF program focuses on current, globally oriented topics crucial to the security of not only the US but to that of all nations. The CIF is an academic-year program that involves both teachers and students in the process of seeking solutions for real world concerns. Built around issues tied to LANL`s mission, participating students and teachers are asked to critically investigate and examine the interactions among the political, social, economic, and scientific domains while considering diversity issues that include geopolitical entities and cultural and ethnic groupings. Participants are expected to collaborate through telecommunications during the research phase and participate in a culminating multimedia activity, where they produce and deliver recommendations for the current issues being studied. The CIF was evaluated and found to be an effective approach for teacher professional training, especially in the development of skills for critical thinking and questioning. The CIF contributed to students` ability to integrate diverse disciplinary content about science-related topics and supported teachers in facilitating the understanding of their students using the CIF approach. Networking technology in CIF has been used as an information repository, resource delivery mechanism, and communication medium.

  2. Quantum Computers: A New Paradigm in Information Technology

    Mahesh S. Raisinghani

    2001-01-01

    Full Text Available The word 'quantum' comes from the Latin word quantus meaning 'how much'. Quantum computing is a fundamentally new mode of information processing that can be performed only by harnessing physical phenomena unique to quantum mechanics (especially quantum interference. Paul Benioff of the Argonne National Laboratory first applied quantum theory to computers in 1981 and David Deutsch of Oxford proposed quantum parallel computers in 1985, years before the realization of qubits in 1995. However, it may be well into the 21st century before we see quantum computing used at a commercial level for a variety of reasons discussed in this paper. The subject of quantum computing brings together ideas from classical information theory, computer science, and quantum physics. This paper discusses some of the current advances, applications, and chal-lenges of quantum computing as well as its impact on corporate computing and implications for management. It shows how quantum computing can be utilized to process and store information, as well as impact cryptography for perfectly secure communication, algorithmic searching, factorizing large numbers very rapidly, and simulating quantum-mechanical systems efficiently. A broad interdisciplinary effort will be needed if quantum com-puters are to fulfill their destiny as the world's fastest computing devices.

    Science.gov (United States)

    Johnson, William

    2005-01-01

    This article explains how computing technology was used to address the need for mobile communications among nursing staff. In 2004, nursing staff at Fauquier Hospital relocated from one nursing floor in an older building to two floors in a new structure. This resulted in complaints and supervision issues as nursing managers, who had previously been relatively sedentary, now became quite mobile as they attempted to control nursing operations on two separate floors. Complaints arose from several sources. Nursing staff and managers both complained about the increased difficulty in communicating with each other Physicians expressed frustration to hospital administration at playing "telephone tag" with managers. The solution involved Internet Protocol technology that is in widespread use on most computer networks. The article details how this technology was selected over several other communications technologies and used to implement wireless telephony over the hospital's existing computer network. It reviews key standards and technologies and issues surrounding their use. Finally, the article demonstrates how this computing technology improved patient care by facilitating mobile communications.

    2015-12-01

    Recent technological advances have much potential for improving police performance, but there has been little research testing whether they have made police more effective in reducing crime. To study the uses and crime control impacts of mobile computing technology in the context of geographically focused "hot spots" patrols. An experiment was conducted using 18 crime hot spots in a suburban jurisdiction. Nine of these locations were randomly selected to receive additional patrols over 11 weeks. Researchers studied officers' use of mobile information technology (IT) during the patrols using activity logs and interviews. Nonrandomized subgroup and multivariate analyses were employed to determine if and how the effects of the patrols varied based on these patterns. Officers used mobile computing technology primarily for surveillance and enforcement (e.g., checking automobile license plates and running checks on people during traffic stops and field interviews), and they noted both advantages and disadvantages to its use. Officers did not often use technology for strategic problem-solving and crime prevention. Given sufficient (but modest) dosages, the extra patrols reduced crime at the hot spots, but this effect was smaller in places where officers made greater use of technology. Basic applications of mobile computing may have little if any direct, measurable impact on officers' ability to reduce crime in the field. Greater training and emphasis on strategic uses of IT for problem-solving and crime prevention, and greater attention to its behavioral effects on officers, might enhance its application for crime reduction. © The Author(s) 2016.

    NASA researcher Dr. Donald Frazier uses a blue laser shining through a quartz window into a special mix of chemicals to generate a polymer film on the inside quartz surface. As the chemicals respond to the laser light, they adhere to the glass surface, forming optical films. Dr. Frazier and Dr. Mark S. Paley developed the process in the Space Sciences Laboratory at NASA's Marshall Space Flight Center in Huntsville, AL. Working aboard the Space Shuttle, a science team led by Dr. Frazier formed thin-films potentially useful in optical computers with fewer impurities than those formed on Earth. Patterns of these films can be traced onto the quartz surface. In the optical computers of the future, thee films could replace electronic circuits and wires, making the systems more efficient and cost-effective, as well as lighter and more compact.

    1992-05-01

    The current practice for the design analysis of new airframe structural systems is to construct a master finite element model of the vehicle in order to develop internal load distributions. The inputs to this model include the geometry which is taken directly from CADAM and CATIA structural layout and aerodynamic loads and mass distribution computer models. This master model is sufficiently detailed to define major load paths and for the computation of dynamic mode shapes and structural frequencies, but not detailed enough to define local stress gradients and notch stresses. This master model is then used to perform structural optimization studies that will provide minimum weights for major structural members. The post-processed output from the master model, load, stress, and strain analysis is then used by structural analysts to perform detailed stress analysis of local regions in order to design local structure with all its required details. This local analysis consists of hand stress analysis and life prediction analysis with the assistance of manuals, design charts, computer stress and structural life analysis and sometimes finite element or boundary element analysis. The resulting design is verified by fatigue tests.

    Nordal, Ola

    One may characterize the history of computing at the Norwegian University of Science and Technology by a tension between the computer as a tool in other disciplines and computer science as discipline in itself. This tension has been latent since the pioneering period of the 1950s until today. This paper shows how this have been expressed in the early attempts to take up computing at the University, and how it gave the Division of Computer Science a fairly rough start when it opened in 1972.

    The flash smelting process has been extensively studied during its over 40 years existence. Laboratory or pilot scale experiments can not, however, predict all the complicated and coupled phenomena taking place in a flash smelting furnace. Development of commercial modelling software and increasingly efficient computers have brought a new tool to researchers for more comprehensive investigation of the transport and combustion processes taking place in the flash smelting process. A flash smelting furnace and a waste-heat boiler geometry have been simulated in two- and three-dimensional laboratory models which have, in turn, been modeled by using commercial Computational-Fluid-Dynamics -software. The computer simulation has then been extended to an industrial-scale furnace and waste-heat boiler. The work has proceeded from cold gas flow to heat transfer, combustion, and two-phase flow simulations. In the present approach, the modelling task has been divided into submodels. Outlet values of a model are used as inlet values in the subsequent submodel. Heat transfer calculations have been carried out starting from very basic considerations. Different options of the software and heat transfer modes have been tested, and hot gas flow through the furnace and boiler has been simulated. Validation of the models was carried out with temperature measurements from the uptake shaft. Also one geometrical variation of the uptake shaft has been simulated, namely turning the outlet of the shaft 90 degrees. Combustion of sulphides is approximated with gaseous combustion by using a built-in combustion model of the software. The waste-heat boiler has been simulated first as an empty geometry, and adding gradually approximated radiation curtains and convection tube bundles. Both convection and radiation heat transfer were considered. (orig.)

    The technology activities carried out by the Euratom-ENEA Association in the framework of the European Fusion Development Agreement concern the Next Step (International Thermonuclear Experimental Reactor - ITER), the Long-Term Programme (breeder blanket, materials, International Fusion Materials Irradiation Facility - IFMIF), Power Plant Conceptual Studies and Socio-Economic Studies. The Underlying Technology Programme was set up to complement the fusion activities as well to develop technologies with a wider range of interest. The Technology Programme mainly involves staff from the Frascati laboratories of the Fusion Technical and Scientific Unit and from the Brasimone laboratories of the Advanced Physics Technologies Unit. Other ENEA units also provide valuable contributions to the programme. ENEA is heavily engaged in component development/testing and in design and safety activities for the European Fusion Technology Programme. Although the work documented in the following covers a large range of topics that differ considerably because they concern the development of extremely complex systems, the high level of integration and coordination ensures the capability to cover the fusion system as a whole. In 2004 the most significant testing activities concerned the ITER primary beryllium-coated first wall. In the field of high-heat-flux components, an important achievement was the qualification of the process for depositing a copper liner on carbon fibre composite (CFC) hollow tiles. This new process, pre-brazed casting (PBC), allows the hot radial pressing (HRP) joining procedure to be used also for CFC-based armour monoblock divertor components. The PBC and HRP processes are candidates for the construction of the ITER divertor. In the materials field an important milestone was the commissioning of a new facility for chemical vapour infiltration/deposition, used for optimising silicon carbide composite (SiCf/SiC) components. Eight patents were deposited during 2004

    CERN Document Server

    Parisi, Luciana

    2013-01-01

    In Contagious Architecture, Luciana Parisi offers a philosophical inquiry into the status of the algorithm in architectural and interaction design. Her thesis is that algorithmic computation is not simply an abstract mathematical tool but constitutes a mode of thought in its own right, in that its operation extends into forms of abstraction that lie beyond direct human cognition and control. These include modes of infinity, contingency, and indeterminacy, as well as incomputable quantities underlying the iterative process of algorithmic processing. The main philosophical source for the project is Alfred North Whitehead, whose process philosophy is specifically designed to provide a vocabulary for "modes of thought" exhibiting various degrees of autonomy from human agency even as they are mobilized by it. Because algorithmic processing lies at the heart of the design practices now reshaping our world -- from the physical spaces of our built environment to the networked spaces of digital culture -- the nature o...

    How does a person's mood during technology training influence motivation, intentions, and, ultimately, usage of the new technology? Do these mood effects dissipate or are they sustainable over time? A repeated-measures field study (n = 316) investigated the effect of mood on employee motivation and intentions toward using a specific computer technology at two points in time: immediately after training and 6 weeks after training. Actual usage behavior was assessed for 12 weeks after training. Each individual was assigned to one of three mood treatments: positive, negative, or control. Results indicated that there were only short-term boosts in intrinsic motivation and intention to use the technology among individuals in the positive mood intervention. However, a long-term lowering of intrinsic motivation and intention was observed among those in the negative mood condition. Copyright 1999 Academic Press.

    Óscar Javier Espitia Mendoza

    2016-02-01

    Full Text Available Computed tomography is a noninvasive scan technique widely applied in areas such as medicine, industry, and geology. This technique allows the three-dimensional reconstruction of the internal structure of an object which is lighted with an X-rays source. The reconstruction is formed with two-dimensional cross-sectional images of the object. Each cross-sectional is obtained from measurements of physical phenomena, such as attenuation, dispersion, and diffraction of X-rays, as result of their interaction with the object. In general, measurements acquisition is performed with methods based on any of these phenomena and according to various architectures classified in generations. Furthermore, in response to the need to simulate acquisition systems for CT, software dedicated to this task has been developed. The objective of this research is to determine the current state of CT techniques, for this, a review of methods, different architectures used for the acquisition and some of its applications is presented. Additionally, results of simulations are presented. The main contributions of this work are the detailed description of acquisition methods and the presentation of the possible trends of the technique.

    An industrial-scale flash smelting furnace and waste-heat boilers have been modelled by using commercial Computational-Fluid-Dynamics software. The work has proceeded from cold gas flow to heat transfer, combustion, and two-phase flow simulations. In the present study, the modelling task has been divided into three sub-models: (1) the concentrate burner, (2) the flash smelting furnace (reaction shaft and uptake shaft), and (3) the waste-heat boiler. For the concentrate burner, the flow of the process gas and distribution air together with the concentrate or a feed mixture was simulated. Eulerian - Eulerian approach was used for the carrier gas-phase and the dispersed particle-phase. A large parametric study was carried out by simulating a laboratory scale burner with varying turbulence intensities and then extending the simulations to the industrial scale model. For the flash smelting furnace, the simulation work concentrated on gas and gas-particle two-phase flows, as well as the development of combustion model for sulphide concentrate particles. Both Eulerian and Lagrangian approaches have been utilised in describing the particle phase and the spreading of the concentrate in the reaction shaft as well as the particle tracks have been obtained. Combustion of sulphides was first approximated with gaseous combustion by using a built-in combustion model of the software. The real oxidation reactions of the concentrate particles were then coded as a user-defined sub-routine and that was tested with industrial flash smelting cases. For the waste-heat boiler, both flow and heat transfer calculations have been carried out for an old boiler and a modified boiler SULA 2 Research Programme; 23 refs.

    With the explosion of computerization, it appears that the business community is switching to computer-based presentations, projecting onto a screen directly from a computer, instead of the old standard of presenting with slides. However, the dental profession has been slow to follow. Although some speakers have switched to computer-based presentations, slides are still the standard in 1998. With the advent of numerous new computer software programs, clinicians are now able to generate highly sophisticated slides, that can be an equally powerful medium to communicate with the audience. Unfortunately, many clinicians are not taking advantage of the benefits of this technology. This article explains the simplicity of generating professional, high quality slides, reviews the major programs and equipment available to accomplish this task, and previews the multitude of applications this technology offers to practitioners as well as educators.

  11. Who's wired and who's not: children's access to and use of computer technology.

    Science.gov (United States)

    Becker, H J

    2000-01-01

    As computer technology becomes increasingly prevalent throughout society, concerns have been raised about an emerging "digital divide" between those children who are benefitting and those who are being left behind. This article presents results from new analyses of national survey data describing children's differential access to computers in school and at home, and the varying conditions that affect how children experience computers. For example, responses from a nationwide survey of teachers suggest that, as of 1998, more than 75% of students had access to computers at school. In fact, those teaching lower-income students reported weekly use of computers more often than those teaching higher-income students. But the nature of children's experiences using computers in school varied greatly by subject and teacher objectives, and the data suggest that lower-income students use computers more often for repetitive practice, whereas higher-income students use computers more often for more sophisticated, intellectually complex applications. Differences between low-income and high-income children's access to home computers were far less subtle. Survey data indicate that only about 22% of children in families with annual incomes of less than $20,000 had access to a home computer, compared to 91% of those in families with annual incomes of more than $75,000. And among children with access, those in low-income families were reported to use the computer less than those in high-income families, perhaps because most low-income families with computers lacked a connection to the Internet. The two most predictive factors of children's use of home computers were the child's age and the computer's capabilities. The author concludes that home access to computers will be a continued area of inequality in American society, and that schools must play a critical role in ensuring equal opportunity for less-advantaged children to access the benefits of the more intellectually powerful

    2010-06-01

    Full Text Available The purpose of this study is to identify the relationship between pre-service teachers’ computer competencies, the perception of technology use and the attitudes toward teaching career. This study based on a survey method and the participants consist of 106 pre-service teachers from the department of elementary education and social sciences education at Ahi Evran University Faculty of Education. One of results is that the participants think that they have a higher level of computer competencies. Another result is that although the participants from elementary education have a higher perception of computer competency than do the participants from social science education, but this result is found statistically insignificant. The pre-service teachers’ belief on the positive effects of technology in teacher education is found high for both departments. The perception of pre-service teachers on technology use is generally positive. This positive perception level affects the attitude toward teaching career positively. As the pre-service teachers level of computer literacy the positive attitude toward technology use gets higher.

    Perdue, Bonnie M; Clay, Andrea W; Gaalema, Diann E; Maple, Terry L; Stoinski, Tara S

    2012-01-01

    A computer-controlled touchscreen apparatus (hereafter referred to as "touchscreen") in the orangutan exhibit at Zoo Atlanta provides enrichment to the animals and allows cognitive research to take place on exhibit. This study investigated the impact of the touchscreen on orangutan behavior and visibility, as well as its impact on zoo visitors. Despite previous research suggesting that providing a single computer system may negatively affect orangutan behavior, there was not a significant increase in aggression, stereotypic, or distress-related behaviors following the activation of the on-exhibit touchscreen. We also investigated the possibility that zoo visitors may be negatively affected by technology because it deviates from naturalism. However, we did not find a change in stay time or overall experience rating when the computer was turned on. This research was the first to assess visitor attitudes toward technology at the zoo, and we found that visitors report highly positive attitudes about technology for both animals and visitors. If subjects visited the exhibit when the computer was turned on, they more strongly agreed that orangutans benefit from interacting with computerized enrichment. This study is the first investigation of an on-exhibit touchscreen in group-housed apes; our findings of no negative effects on the animals or zoo visitors and positive attitudes toward technology suggest a significant value of this practice.
