Neo-Institutional Approach to the Study of Electronic Government

Directory of Open Access Journals (Sweden)

Yan I. Vaslavskiy

2016-01-01

Full Text Available The article is devoted to the neo-institutional approach as a methodological basis in the study of electronic government. In this article substantiates the choice of neo-institutional approach to the study of the processes of implementation of information and communication technologies in the activity of state institutions, analyzes the differences of neoinstitutionalism from traditional institutional approach, considers the features of the different directions of neo-institutionalism, namely sociological, historical and rational choice theory. Attention is paid to the reasons for the renewed interest in political institutions in political science. The article emphasizes the importance of considering the electronic government as an institution, and the conditions for its implementation in the Russian political system as the institutional environment. The authors pay special attention to the variety of sociological neo-institutionalism, used, in addition to political science in sociology of organizations. The article substantiates the value of using sociological institutionalism to explore the electronic government based on a comparative analysis of e-government projects in Russia and abroad and explores its heuristic capabilities. It examines the impact of the system of norms and values of the institutional environment on the processes of formation and development of electronic government in Russia. The research capacity of this theory is due to the fact that it allows us to trace the reasons for copying and replication of inefficient practices and organizational and management schemes, to identify the factors impeding innovation use by the state of electronic interaction technologies. It is emphasized that the use of the theory of institutional isomorphism is useful in the sphere of implementation of electronic technologies, in which a key role play pluralism, horizontal managerial communication, inter-agency coordination.

Inverse-Electron-Demand Diels-Alder Reactions: Principles and Applications.

Science.gov (United States)

Png, Zhuang Mao; Zeng, Huining; Ye, Qun; Xu, Jianwei

2017-09-05

Inverse-electron-demand Diels-Alder (iEDDA) reactions are an intriguing class of cycloaddition reactions that have attracted increasing attention for their application in bioorthogonal chemistry, the total synthesis of natural products, and materials science. In many cases, the application of the iEDDA reaction has been demonstrated as an innovative approach to achieve target structures. The theoretical aspects of this class of reactions are of particular interest for scientists as a means to understand the various factors, such as steric strain and electron density of the attached groups, that govern the reaction and thus to elucidate the reaction mechanism. This review aims to summarize both theoretical investigations and application-driven research work on the iEDDA reaction. First, the historical aspects and the theoretical basis of the reaction, especially recent advances in time-dependent density functional theory (TD-DFT) calculations, as well as catalysis strategies will be highlighted and discussed. Second, the applications of this novel reaction in the context of materials science, bioorthogonal chemistry, and total synthesis of natural products will be elaborated with selected recent examples. The challenges and opportunities of the iEDDA reaction will be highlighted to give more insight into its potential applications in many other research areas. © 2017 Wiley-VCH Verlag GmbH & Co.

Many governments around the world increasingly use internet technologies such as electronic government to provide public services. These services range from providing the most basic informational website to deploying sophisticated tools for managing interactions between government agencies and beyond government. Electronic government (e-government) aims to provide a more accurate, easily accessible, cost-effective and time saving for the community. In this study, we develop a new model of e-government adoption service by extending the Unified Theory of Acceptance and Use of Technology (UTAUT) through the incorporation of some variables such as System Quality, Information Quality and Trust. The model is then tested using a large-scale, multi-site survey research of 237 Indonesian citizens. This model will be validated by using Structural Equation Modeling (SEM). The result indicates that System Quality, Information Quality and Trust variables proven to effect user behavior. This study extends the current understanding on the influence of System Quality, Information Quality and Trust factors to researchers, practitioners, and policy makers.

Trust in government and support for governmental regulation: the case of electronic health records.

Science.gov (United States)

Herian, Mitchel N; Shank, Nancy C; Abdel-Monem, Tarik L

2014-12-01

This paper presents results from a public engagement effort in Nebraska, USA, which measured public opinions about governmental involvement in encouraging the use of electronic health records (EHRs). We examine the role of trust in government in contributing to public support for government involvement in the development of EHR technologies. We hypothesize that trust in government will lead to support for federal and state governmental encouragement of the use of EHRs among doctors and insurance companies. Further, because individual experiences with health-care professionals will reduce perceptions of risk, we expect that support for governmental involvement will be tempered by greater personal experience with the health-care industry. Examining a small survey of individuals on the issue, we find general support for both of our hypotheses. The findings suggest that trust in government does have a positive relationship with support for government involvement in the policy domain, but that the frequency of personal experiences with health-care providers reduces the extent to which the public supports governmental involvement in the development of EHR technology. This inquiry contributes to our understanding of public attitudes towards government involvement in EHRs in the United States specifically and contributes to social science examining links between trust in government and support for governmental activity in the emerging policy domain regarding electronic health records systems. © 2012 John Wiley & Sons Ltd.

Envisioning Advanced User Interfaces for E-Government Applications: A Case Study

Science.gov (United States)

Calvary, Gaëlle; Serna, Audrey; Coutaz, Joëlle; Scapin, Dominique; Pontico, Florence; Winckler, Marco

The increasing use of the Web as a software platform together with the advance of technology has promoted Web applications as a starting point for improving communication between citizens and administration. Currently, several e-government Web portals propose applications for accessing information regarding healthcare, taxation, registration, housing, agriculture, education, and social services, which otherwise may be difficult to obtain. However, the adoption of services provided to citizens depends upon how such applications comply with the users' needs. Unfortunately, building an e-government website doesn't guarantee that all citizens who come to use it can access its contents. These services need to be accessible to all citizens/customers equally to ensure wider reach and subsequent adoption of the e-government services. User disabilities, computer or language illiteracy (e.g., foreign language), flexibility on information access (e.g., user remotely located in rural areas, homeless, mobile users), and ensuring user privacy on sensitive data are some of the barriers that must be taken into account when designing the User Interface (UI) of e-government applications.

Goldman, G. T.; Carter, J. M.; Licker, R.

2017-12-01

Climate scientists have long faced politicization of their work, especially those working within the US federal government. However, political interference in federal government climate change science has escalated in the current political era with efforts by political actors to undermine and disrupt infrastructure supporting climate science. This has included funding changes, decreased access to climate science information on federal agency websites, restrictions on media access to scientific experts within the government, and rolling back of science-based policies designed to incorporate and respond to climate science findings. What are the impacts of such changes for both the climate science community and the broader public? What can be done to ensure that access to and application of climate change-related research to policy decisions continues? We will summarize and analyze the state of climate change research and application in the US government. The impacts of political interference in climate change science as well as opportunities the scientific community has to support climate science in the US government, will be discussed.

Industrial applications of electron accelerators

International Nuclear Information System (INIS)

Singh, A.

1994-01-01

The interaction of high-energy radiation with organic systems produces very reactive, short-lived, ionic and free-radical species. The chemical changes brought about by these species are very useful in several systems, and are the basis of the growth of the electron processing industry. Some typical areas of the industrial use of electron accelerators are crosslinking wire and cable insulation, manufacturing heat shrink plastic items, curing coatings, and partially curing rubber products. Electron accelerators are also being considered in other areas such as sewage treatment, sterilizing medical disposables, and food irradiation. An emerging application of industrial electron accelerators is the production of advanced composites for the aerospace and other industries. Traditionally, the carbon-, aramid- and glass-fibre-reinforced composites with epoxy matrices are produced by thermal curing. However, equivalent composites with acrylated-epoxy matrices can be made by electron curing. Cost estimates suggest that electron curing could be more economical than thermal curing. Food irradiation has traditionally been an application for 60 Co γ-radiation. With the increasing demand for food irradiation in various countries, it may become necessary to use electron accelerators for this purpose. Since the dose rate during gamma and electron irradiation are generally very different, a review of the relevant work on the effect of dose rates has been done. This paper presents an overview of the industrial applications of electron accelerator for radiation processing, emphasises the electron curing of advanced composites and, briefly reviews the dose-rate effects in radiation processing of advanced composites and food irradiation.

Industrial applications of electron accelerators

CERN Document Server

Cleland, M R

2006-01-01

This paper addresses the industrial applications of electron accelerators for modifying the physical, chemical or biological properties of materials and commercial products by treatment with ionizing radiation. Many beneficial effects can be obtained with these methods, which are known as radiation processing. The earliest practical applications occurred during the 1950s, and the business of radiation processing has been expanding since that time. The most prevalent applications are the modification of many different plastic and rubber products and the sterilization of single-use medical devices. Emerging applications are the pasteurization and preservation of foods and the treatment of toxic industrial wastes. Industrial accelerators can now provide electron energies greater than 10 MeV and average beam powers as high as 700 kW. The availability of high-energy, high-power electron beams is stimulating interest in the use of X-rays (bremsstrahlung) as an alternative to gamma rays from radioactive nuclides.

2014-02-01

This paper will present an outlook on sources of radiation, focusing on electron accelerators. We will review advances that were important for the development of particle accelerators, concentrating on those that led to modern electron accelerators. Electron accelerators are multipurpose machines that deliver beams with energies spanning five orders of magnitude, and are used in applications that range from fundamental studies of particle interactions to cross-linking polymer chains in industrial plants. Each accelerator type presents specific characteristics that make it more suitable for certain applications. Our work will focus on radiation sources for medical applications, dominated by electron linacs (linear accelerators), and those used for research, field where electron rings dominate. We will outline the main technological advances that occurred in the past decades, which made possible the construction of machines fit for clinical environments. Their compactness, efficiency and reliability have been key to their acceptance in clinical applications. This outline will include advances that allowed for the construction of brighter synchrotron light sources, where the relevant beam characteristics are good optical quality and high beam current. The development of insertion devices will also be discussed, as well the development of Free Electron Lasers (FEL). We conclude the review with an outline of the new developments of electron accelerators and the expectations for Energy Recovery Linacs.

We will review advances that were important for the development of particle accelerators, concentrating on those that led to modern electron accelerators. Electron accelerators are multipurpose machines that deliver beams with energies spanning five orders of magnitude, and are used in applications that range from fundamental studies of particle interactions to cross-linking polymer chains in industrial plants. Each accelerator type presents specific characteristics that make it more suitable for certain applications. Our work will focus on radiation sources for medical applications, dominated by electron linacs (linear accelerators), and those used for research, field where electron rings dominate. We will outline the main technological advances that occurred in the past decades, which made possible the construction of machines fit for clinical environments. Their compactness, efficiency and reliability have been key to their acceptance in clinical applications. This outline will include advances that allowed for the construction of brighter synchrotron light sources, where the relevant beam characteristics are good optical quality and high beam current. The development of insertion devices will also be discussed, as well the development of Free Electron Lasers (FEL). We conclude the review with an outline of the new developments of electron accelerators and the expectations for Energy Recovery Linacs. - Highlights: ► We present an outlook on sources of radiation, focusing on electron accelerators. ► We review important advances for the development of modern electron accelerators. ► We outline advances that allowed for brighter synchrotron light sources. ► We describe the history of the development of electron accelerators in Brazil

Scattered radiation from applicators in clinical electron beams

International Nuclear Information System (INIS)

Battum, L J van; Zee, W van der; Huizenga, H

2003-01-01

In radiotherapy with high-energy (4-25 MeV) electron beams, scattered radiation from the electron applicator influences the dose distribution in the patient. In most currently available treatment planning systems for radiotherapy this component is not explicitly included and handled only by a slight change of the intensity of the primary beam. The scattered radiation from an applicator changes with the field size and distance from the applicator. The amount of scattered radiation is dependent on the applicator design and on the formation of the electron beam in the treatment head. Electron applicators currently applied in most treatment machines are essentially a set of diaphragms, but still do produce scattered radiation. This paper investigates the present level of scattered dose from electron applicators, and as such provides an extensive set of measured data. The data provided could for instance serve as example input data or benchmark data for advanced treatment planning algorithms which employ a parametrized initial phase space to characterize the clinical electron beam. Central axis depth dose curves of the electron beams have been measured with and without applicators in place, for various applicator sizes and energies, for a Siemens Primus, a Varian 2300 C/D and an Elekta SLi accelerator. Scattered radiation generated by the applicator has been found by subtraction of the central axis depth dose curves, obtained with and without applicator. Scattered radiation from Siemens, Varian and Elekta electron applicators is still significant and cannot be neglected in advanced treatment planning. Scattered radiation at the surface of a water phantom can be as high as 12%. Scattered radiation decreases almost linearly with depth. Scattered radiation from Varian applicators shows clear dependence on beam energy. The Elekta applicators produce less scattered radiation than those of Varian and Siemens, but feature a higher effective angular variance. The scattered

The development of mountain risk governance: challenges for application

Science.gov (United States)

Link, S.; Stötter, J.

2015-01-01

The complexity the management of mountain risks in the Alps has considerably increased since its institutionalisation in the late nineteenth century. In the history of approaches to dealing with mountain risks four successive paradigms can be distinguished on the basis of key indicators such as guiding principles, characteristic elements and typical instruments: "hazard protection", "hazard management", "risk management", and "risk governance". In this contribution, special attention is paid to the development of hazard zone planning and the growing importance of communication and participation over the course of this transformation. At present, the risk management paradigm has reached maturity. In the Alps, risk governance frameworks are not yet applied to risks from natural hazards. Based on a historical analysis, the suitability and applicability of general risk governance frameworks in the context of mountain risks are discussed. Necessary adaptations (e.g., in administration, educational, and legal structures) are proposed for the upcoming transformation towards mountain risk governance.

Dimer and cluster approach for the evaluation of electronic couplings governing charge transport: Application to two pentacene polymorphs

International Nuclear Information System (INIS)

Canola, Sofia; Pecoraro, Claudia; Negri, Fabrizia

2016-01-01

Hole transport properties are modeled for two polymorphs of pentacene: the single crystal polymorph and the thin film polymorph relevant for organic thin-film transistor applications. Electronic couplings are evaluated in the standard dimer approach but also considering a cluster approach in which the central molecule is surrounded by a large number of molecules quantum-chemically described. The effective electronic couplings suitable for the parametrization of a tight-binding model are derived either from the orthogonalization scheme limited to HOMO orbitals and from the orthogonalization of the full basis of molecular orbitals. The angular dependent mobilities estimated for the two polymorphs using the predicted pattern of couplings display different anisotropy characteristics as suggested from experimental investigations.

Electron Energy-Loss Spectroscopy: Fundamentals and applications in the characterization of minerals

International Nuclear Information System (INIS)

Krishnan, K.M.

1989-04-01

The combined use of an energy-loss spectrometer and an analytical electron microscope with fine probe forming capabilities provides a wealth of information about the sample at high spatial resolution. Fundamental principles governing the physics of the interaction between the fast electron and a thin foil sample, to account for the fine structure in the inelastically scattered fast electron distribution (Electron-Energy Loss Spectroscopy, EELS), will be reviewed. General application of EELS is in the area of low atomic number elements (Z < 11) microanalysis, where it significantly complements the more widely used Energy Dispersive X-ray Spectroscopy (EDXS). However, a careful analysis of the low loss plasmon oscillations and the fine structure in the core-loss edges, can provide additional information related to the bonding and electronic structure of the sample. An illustration of this is presented from our study of Cδ diamond residue from the Allende carbonaceous chondrite. Combination of EELS with channeling effects can provide specific site occupation/valence information in crystalline materials. Details of this novel crystallographic method will be outlined and illustrated with an example of the study of chromite spinels. Finally, some pertinent experimental details will be discussed. 7 figs

An Analysis of the Regulatory Environment Governing Hearsay Electronic Evidence in South Africa: Suggestions for Reform – Part One

Directory of Open Access Journals (Sweden)

Lee Swales

2018-03-01

Full Text Available The purpose of this two-part article is to examine the regulatory environment governing hearsay electronic evidence in South Africa – with a view to providing clear, practical suggestions for regulatory reform in the context of the South African Law Reform Commission's most recent Discussion Paper on electronic evidence. Technology has become an indispensable part of modern life. In particular, the Internet has facilitated new forms of business enterprise, and shifted basic communication norms. From a legal perspective, technology has presented several novel challenges for courts and legal practitioners to deal with – one of these key challenges relates to electronic evidence and in particular the application of the hearsay rules to the digital environment. The South African Law Reform Commission has identified the application of the hearsay rule as one of the core concerns with regard to electronic evidence, and certain academic analysis has revealed inefficiency in the current legal position which may involve multiple sources of law. Moreover, the Law Society of South Africa has stated that there is some confusion amongst members of the profession in relation to hearsay as it applies to electronic evidence. With the pervasive and burgeoning nature of technology, and with the Internet in mind, it is natural to assume that electronic evidence will be relevant in most forms of legal proceedings in future, and hearsay electronic evidence in particular will play an increasingly important role in years to come. Consequently, part one of this article will consider the key definitional concept in relation to electronic evidence – data messages - and examine whether the definition should be revised. In addition, part one of this article will answer two further critical questions posed by the South African Law Reform Commission in relation to data messages and hearsay evidence, namely: should a data message constitute hearsay? And, how should one

Technology of electron accelerator have been developed so fast in advanced countries. It was applied in the research and development (R and D) and comercially in various industries. The industries applying electron accelerator includes polymers industry, sterilization of medical tools, material surface modification, and environmental management. The radiation process using electron beam is an ionization radiation process. Two facilities of electron accelerator have been established in pilot scale at the Centre for the Application of Isotope and Radiation CAIR-BATAN, Jakarta, for the RandD of radiation process technology and in demonstrating the electron accelerator application in industry in Indonesia. The first has low energy specification of 300 keV, 50 mA, EPS-300 type and the second has medium energy specification of 2 MeV, 10 mA dynamitron model GJ-2 type. Both the electron accelerators have an electron penetration depth capability of 0.6 and 12 mm, respectively, for the double side irradiation in the materials with density of 1 g/cm 3 . They also highly capacity production and electron beam cross-section of 120 cm length and 10 cm width. The beam will go through the atmosphere for irradiation samples or industrial products. The radiation dose can be selected precisely by adjusting the electron beam current and conveyor speed. Both of these facilities were applied in many aspects RandD, for examples dosimetry, wood surface coating, cross-linking of polymer, heatshrincable tube, polymer grafting, plastic degradation, food preservation, sterilization and so on. Engineering factors of radiation design process and general observation of electron accelerator application in RandD for various industries in Indonesia are briefly discussed

Adhesion-governed buckling of thin-film electronics on soft tissues

Bo Wang

2016-01-01

Full Text Available Stretchable/flexible electronics has attracted great interest and attention due to its potentially broad applications in bio-compatible systems. One class of these ultra-thin electronic systems has found promising and important utilities in bio-integrated monitoring and therapeutic devices. These devices can conform to the surfaces of soft bio-tissues such as the epidermis, the epicardium, and the brain to provide portable healthcare functionalities. Upon contractions of the soft tissues, the electronics undergoes compression and buckles into various modes, depending on the stiffness of the tissue and the strength of the interfacial adhesion. These buckling modes result in different kinds of interfacial delamination and shapes of the deformed electronics, which are very important to the proper functioning of the bio-electronic devices. In this paper, detailed buckling mechanics of these thin-film electronics on elastomeric substrates is studied. The analytical results, validated by experiments, provide a very convenient tool for predicting peak strain in the electronics and the intactness of the interface under various conditions.

The literature starts using a new concept, a new form of association – artificial intelligence society – foreseen to be established in the next time frame. All these developments of human society and translations or leaps (most of the times apparently timeless were, are and will be possible only due to the advancing information and communications technologies. The leap to Democracy 3.0, based on information and communication technologies prompts to a radical change in the majority of the classical concepts targeting society structure and the way it is guided and controlled. Thus, concepts become electronic concepts (or e-concepts through the use of new technologies. E-concepts keep the essence of the classical principles of liberty and democracy, adding a major aspect of the new way of communication and spreading ideas between people. The main problem is to quantify, analyze and foresee the way technological changes will influence not only the economic system, but also the daily life of the individual and the society. Unfortunately (or maybe fortunately, depending on the point of view, all these evolutions and technological and social developments are as many challenges for the governments of the world. In this paper we will highlight only four of the challenges facing the governments, grouped in a structured model with the following specific concepts: Big Data, Social Data, Linked Data and Mobile Data. This is an emerging paradigm of the information and communication technology supporting national and global eGovernment projects.

Full Text Available As electronic government services (e-government evolve, traditional applications such as online portals are encountering challenges in a new digital era in which people thirst for more convenient, diverse channels of communication with their government. Despite the efforts devoted to the promotion of Social Networking Service (SNS use in e-government for the past few years, empirical studies regarding this ongoing trend are still insufficient. In the local administration of China, a special collaboration between local governments and private Internet enterprises is happening: government services are imported into commercial SNS platforms known as WeChat and Weibo. This research conducts a case study of a Chinese municipality premised upon survey data (N = 605 collected in Chongqing. It examines the determinants of e-services adoption in four major local applications: two traditional government-led services “Government website portal” and “Government official app” (traditional government-led services, and two built-in government services on social networking applications “Weibo Government official account” “WeChat Public Services”. The paper aims to provide a closer understanding of current trends in local government e-services, or in this case, an innovative trial of Chinese e-government practices.

Project governance: selected South African government experiments

Directory of Open Access Journals (Sweden)

G. van der Walt

2008-07-01

Full Text Available Some form of accountability and power structure binds all organisations. Such structures are typically referred to as the “governance” structure of the organisation. In organisations that have relatively mature project applications and methodologies in place, governance mechanisms are established on more permanent bases. With its focus on performance, results and outcomes, project governance establishes decision-making structures, as well as accountability and responsibility mechanisms in public institutions to oversee projects. As government institutions increasingly place emphasis on project applications for policy implementation and service delivery initiatives, mechanisms or structures should be established to facilitate clear interfaces between the permanent organisation and the temporary project organisation. Such mechanisms or structures should enhance the governance of projects, that is, the strategic alignment of projects, the decentralisation of decision- making powers, rapid resource allocation, and the participation of external stakeholders. The purpose of this article is to explore the concept “project governance”, and to highlight examples of project governance as applied in selected government departments in provincial and national spheres. This would enable the establishment of best practice examples and assist to develop benchmarks for effective project applications for service delivery improvement.

1997-01-01

Electron beam technology was first introduced in Malaysia in 1989 with the conclusion of the bilateral cooperation between the Malaysian Institute for Nuclear Technology Research (MINT) and Japan International Co-operation Agency (JICA) on Radiation Application Projects. Two electron beam accelerators with energy of 3.0 MeV and 200 keV were installed at MINT. These two accelerators pave the way for R and D to be carried out in radiation processing of polymers for cross-linking and surface curing. In 1994, another electron beam accelerator was installed in the private sector for cross-linking of home appliance wires. Since then, two more accelerators were installed in the private sector for cross-linking of heat shrinkable plastic films. Recently, a local company has acquired a low energy electron beam machine for cross-linking of plastic film. Within a period of 7 years, industrial applications of electron beam technology in Malaysia have increased significantly

Radiation leakage from linac electron applicator assembly

International Nuclear Information System (INIS)

Keys, R.A.; Purdy, J.A.

1984-01-01

The electron beam applicator system currently in use on the linear accelerator is constructed of light-weight fiberglass and aluminum. With an applicator in place on the accelerator, the photon collimator jaws are automatically set several centimeters greater than the electron field size projected at the patient's surface. To ensure that no regions of high dose levels exist outside the useful beam, ionization and film measurements were made to quantitate the amount of leakage radiation through the 10 cm x 10 cm and 25 cm x 25 cm applicators. In most regions, the ionization levels at the patient's surface were below 5% of the central axis dose. In one area for the 25 cm applicator, the percentage ionization was 8.5%, which could be reduced by the addition of a small piece of 1/8 inch thick lead. However, ionization levels on the outside surface of the applicator were found to be considerably higher at certain locations for the 25 cm applicator. Results for 6, 9, 12 and 20 MeV electrons are reported here

Visual Culture and Electronic Government: Exploring a New Generation of E-Government

Science.gov (United States)

Bekkers, Victor; Moody, Rebecca

E-government is becoming more picture-oriented. What meaning do stakeholders attach to visual events and visualization? Comparative case study research show the functional meaning primarily refers to registration, integration, transparency and communication. The political meaning refers to new ways of framing in order to secure specific interests and claims. To what the institutional meaning relates is ambiguous: either it improves the position of citizens, or it reinforces the existing bias presented by governments. Hence, we expect that the emergence of a visualized public space, through omnipresent penetration of (mobile) multimedia technologies, will influence government-citizen interactions.

Interdomain electron transfer in cellobiose dehydrogenase is governed by surface electrostatics.

2017-02-01

Cellobiose dehydrogenase (CDH) is a fungal extracellular oxidoreductase which fuels lytic polysaccharide monooxygenase with electrons during cellulose degradation. Interdomain electron transfer between the flavin and cytochrome domain in CDH, preceding the electron flow to lytic polysaccharide monooxygenase, is known to be pH dependent, but the exact mechanism of this regulation has not been experimentally proven so far. To investigate the structural aspects underlying the domain interaction in CDH, hydrogen/deuterium exchange (HDX-MS) with improved proteolytic setup (combination of nepenthesin-1 with rhizopuspepsin), native mass spectrometry with ion mobility and electrostatics calculations were used. HDX-MS revealed pH-dependent changes in solvent accessibility and hydrogen bonding at the interdomain interface. Electrostatics calculations identified these differences to result from charge neutralization by protonation and together with ion mobility pointed at higher electrostatic repulsion between CDH domains at neutral pH. In addition, we uncovered extensive O-glycosylation in the linker region and identified the long-unknown exact cleavage point in papain-mediated domain separation. Transition of CDH between its inactive (open) and interdomain electron transfer-capable (closed) state is shown to be governed by changes in the protein surface electrostatics at the domain interface. Our study confirms that the interdomain electrostatic repulsion is the key factor modulating the functioning of CDH. The results presented in this paper provide experimental evidence for the role of charge repulsion in the interdomain electron transfer in cellobiose dehydrogenases, which is relevant for exploiting their biotechnological potential in biosensors and biofuel cells.

Zhu, T.; Cloutier, S.G.; Ivanov, I; Knappenberger Jr, K.L.; Robel, I.; Zhang, F

2012-01-01

Electronic and optoelectronic devices, from computers and smart cell phones to solar cells, have become a part of our life. Currently, devices with featured circuits of 45 nm in size can be fabricated for commercial use. However, further development based on traditional semiconductor is hindered by the increasing thermal issues and the manufacturing cost. During the last decade, nano crystals have been widely adopted in various electronic and optoelectronic applications. They provide alternative options in terms of ease of processing, low cost, better flexibility, and superior electronic/optoelectronic properties. By taking advantage of solution-processing, self-assembly, and surface engineering, nano crystals could serve as new building blocks for low-cost manufacturing of flexible and large area devices. Tunable electronic structures combined with small exciton binding energy, high luminescence efficiency, and low thermal conductivity make nano crystals extremely attractive for FET, memory device, solar cell, solid-state lighting/display, photodetector, and lasing applications. Efforts to harness the nano crystal quantum tunability have led to the successful demonstration of many prototype devices, raising the public awareness to the wide range of solutions that nano technology can provide for an efficient energy economy. This special issue aims to provide the readers with the latest achievements of nano crystals in electronic and optoelectronic applications, including the synthesis and engineering of nano crystals towards the applications and the corresponding device fabrication, characterization and computer modeling.

Ishikawa, Tetsuya

2007-01-01

The Laser in the X-ray region has been anticipated to be realized as a light source to probe the nano-world. Free electron lasers using high energy electron accelerators have been promising the candidates. The finding of the principle of Self-Amplified Spontaneous Emission (SASE) resolved the technological difficulties accompanying the X-ray free electron laser, and the construction of large scale SASE facilities started in western countries. In Japan the construction of an SASE facility started in 2006 to be completed in 2010 at the site of the large synchrotron radiation facility, SPring-8 positioned as a 'critical technology of national importance' by the Japanese government. The principle of the X-ray free electron laser is explained and the outline of the Japanese facility construction plan is presented. Also the application of the X-ray laser to the imaging of non-crystalline nano-structure is introduced. (K.Yoshida)

Governance of Offshore IT Outsourcing at Shell Global Functions IT-BAM Development and Application of a Governance Framework to Improve Outsourcing Relationships

Science.gov (United States)

de Jong, Floor; van Hillegersberg, Jos; van Eck, Pascal; van der Kolk, Feiko; Jorissen, Rene

The lack of effective IT governance is widely recognized as a key inhibitor to successful global IT outsourcing relationships. In this study we present the development and application of a governance framework to improve outsourcing relationships. The approach used to developing an IT governance framework includes a meta model and a customization process to fit the framework to the target organization. The IT governance framework consists of four different elements (1) organisational structures, (2) joint processes between in- and outsourcer, (3) responsibilities that link roles to processes and (4) a diverse set of control indicators to measure the success of the relationship. The IT governance framework is put in practice in Shell GFIT BAM, a part of Shell that concluded to have a lack of management control over at least one of their outsourcing relationships. In a workshop the governance framework was used to perform a gap analysis between the current and desired governance. Several gaps were identified in the way roles and responsibilities are assigned and joint processes are set-up. Moreover, this workshop also showed the usefulness and usability of the IT governance framework in structuring, providing input and managing stakeholders in the discussions around IT governance.

Electron Beam Scanning in Industrial Applications

Science.gov (United States)

Jongen, Yves; Herer, Arnold

1996-05-01

Scanned electron beams are used within many industries for applications such as sterilization of medical disposables, crosslinking of wire and cables insulating jackets, polymerization and degradation of resins and biomaterials, modification of semiconductors, coloration of gemstones and glasses, removal of oxides from coal plant flue gasses, and the curing of advanced composites and other molded forms. X-rays generated from scanned electron beams make yet other applications, such as food irradiation, viable. Typical accelerators for these applications range in beam energy from 0.5MeV to 10 MeV, with beam powers between 5 to 500kW and scanning widths between 20 and 300 cm. Since precise control of dose delivery is required in many of these applications, the integration of beam characteristics, product conveyance, and beam scanning mechanisms must be well understood and optimized. Fundamental issues and some case examples are presented.

Hsu, Fang-Ming; Hu, Paul Jen-Hwa; Chen, Hsinchun; Hu, Han-Fen

While e-government is propelling and maturing steadily, advanced technological capabilities alone cannot guarantee agencies’ realizing the full benefits of the enabling computer-based systems. This study analyzes information systems in e-government settings by examining agencies’ satisfaction with an electronic record management system (ERMS). Specifically, we investigate key satisfaction determinants that include regulatory compliance, job relevance, and satisfaction with support services for using the ERMS. We test our model and the hypotheses in it, using a large-scale survey that involves a total of 1,652 government agencies in Taiwan. Our results show significant effects of regulatory compliance on job relevance and satisfaction with support services, which in turn determine government agencies’ satisfaction with an ERMS. Our data exhibit a reasonably good fit to our model, which can explain a significant portion of the variance in agencies’ satisfaction with an ERMS. Our findings have several important implications to research and practice, which are also discussed.

Industrial applications or electron beams

International Nuclear Information System (INIS)

Martin, J. I.

2001-01-01

Industrial use of electron beams began in the 1950's with the crosslinking of polyethylene film and wire insulation. Today the number of electron beam Processing Systems installed for industrial applications throughout the world has grown to more than six hundred stations in over 35 countries. Total installed power is now approaching 40 megawatts (over 8 million tons of products per year). Electron beam is now utilized by many major industries including plastics, automotive, rubber goods, wire and cable, electrical insulation, semiconductor, medical, packaging, or pollution control. The principal effect of high-energy electrons is to produce ions in the materials treated, resulting in the liberation of orbital electrons. As a result, the original molecule is modified and the ree radicals combine to form new molecules with new chemical reactions or dis organisation od the DNA chains of living organisms (insects, fungus, microorganisms, etc.).

Lee, S.; Kim, J.; Lee, S.J.; Kim, K.S.

1997-01-01

The geometrical and electronic structures of partially hydrated electron systems, in particular, the water hexamer, which have been controversial for decades, have been clarified by an exhaustive search for possible low-lying energy structures. Several competing interaction forces governing the conformation have been examined for the first time. The low-lying energy structures are hybrid (or partially internal and partially surface) excess electron states. Our prediction is evidenced from excellent agreements with available experimental data. The vertical electron-detachment energies are mainly determined by the number of dangling H atoms (H d ) . copyright 1997 The American Physical Society

Practical application of corporate governance principles in a developing country: A case study

Directory of Open Access Journals (Sweden)

Wanjiru Gachie

2017-03-01

Full Text Available The importance of examining corporate governance in organisations cannot be overemphasised. Corporate governance failure which has resulted from weak corporate governance systems has highlighted the need for research aimed at contributing to the improvement and reform of corporate governance at business, national and international level. A review of corporate governance mechanisms and their practical application in two retail companies in South Africa was undertaken. The research question that informed the study was: What is the nature of corporate governance mechanisms in the South African retail sector? The research design entailed analysis of secondary data, namely Annual Reports and other pertinent documents, and document analysis was used to show what is accessible to the ordinary share/stake-holder and what is not. Data analysis was conducted both qualitatively and quantitatively. With regard to corporate governance mechanisms, the results and discussion show that the two companies have not yet complied with the King II and III codes. Recommended strategies to strengthen corporate governance mechanisms in the South African retail sector should include a commitment to risk disclosure and revamping of the corporate governance structure of the ‘whole’ system.

Full Text Available The informative society is seen as the central element of rural development at the beginning of the third millennium and the development of information technology and communication in villages has always been considered in current summits across the world. Nowadays, information and communication technology service offices are the basis of electronic government. Therefore, recognition of these offices is necessary for sustainable rural development. The purpose of this research was a comparative analysis between the current situation and the desirable situation of e-government services in the rural districts of the Hamedan province as perceived by their directors (Hamedan, Bahar and Famenin Counties. The study population consists of 91 respondents who were chosen and studied through the census method. The findings of this research study consist of two sections. The items related to satisfaction with the activities in information and communication technology service offices were prioritized in the first section. Moreover, the current and the desirable conditions for electronic service provision were identified. The gap between these two were analyzed in the second section. The results indicate that there is a significant difference between these two conditions of electronic service provisions in rural areas. This significant difference was recognized through the paired T test at the 0.05 level with 6.33 value that illustrates the existence of a gap between these two situations.

Stretchable electronics for wearable and high-current applications

Hilbich, Daniel; Shannon, Lesley; Gray, Bonnie L.

2016-04-01

Advances in the development of novel materials and fabrication processes are resulting in an increased number of flexible and stretchable electronics applications. This evolving technology enables new devices that are not readily fabricated using traditional silicon processes, and has the potential to transform many industries, including personalized healthcare, consumer electronics, and communication. Fabrication of stretchable devices is typically achieved through the use of stretchable polymer-based conductors, or more rigid conductors, such as metals, with patterned geometries that can accommodate stretching. Although the application space for stretchable electronics is extensive, the practicality of these devices can be severely limited by power consumption and cost. Moreover, strict process flows can impede innovation that would otherwise enable new applications. In an effort to overcome these impediments, we present two modified approaches and applications based on a newly developed process for stretchable and flexible electronics fabrication. This includes the development of a metallization pattern stamping process allowing for 1) stretchable interconnects to be directly integrated with stretchable/wearable fabrics, and 2) a process variation enabling aligned multi-layer devices with integrated ferromagnetic nanocomposite polymer components enabling a fully-flexible electromagnetic microactuator for large-magnitude magnetic field generation. The wearable interconnects are measured, showing high conductivity, and can accommodate over 20% strain before experiencing conductive failure. The electromagnetic actuators have been fabricated and initial measurements show well-aligned, highly conductive, isolated metal layers. These two applications demonstrate the versatility of the newly developed process and suggest potential for its furthered use in stretchable electronics and MEMS applications.

Electron accelerator is an important radiation source for radiation technology, which covers broad fields such as industry, health care, food and environmental protection. There are about 1,000 electron accelerators for radiation processing worldwide. Electron accelerator has advantage over Co-60 irradiator in term of high dose rate and power, assurance of safety, and higher economic performance at larger volume of irradiation. Accelerator generating higher energy in the range of 10 MeV and high power electron beam is now commercially available. There is a trend to use high-energy electron accelerator replacing Co-60 in case of large through-put of medical products. Irradiated foods, in particular species, are on the commercial market in 35 countries. Electron accelerator is used efficiently and economically for production of new or modified polymeric materials through radiation-induced cross-linking, grafting and polymerization reaction. Another important application of electron beam is the curing of surface coatings in the manufacture of products. Electron accelerators of large capacity are used for cleaning exhaust gases in industrial scale. Economic feasibility studies of this electron beam process have shown that this technology is more cost effective than the conventional process. It should be noted that the conventional limestone process produce gypsum as a by-product, which cannot be used in some countries. By contrast, the by-product of the electron beam process is a valuable fertilizer. (Y. Tanaka)

The proposed model to achieve this, was developed by one of the authors during his doctoral dissertation (Cardona, 2004 and evaluated by the other one as dissertation judge. It includes five different independent and latent constructs, Attitude, Aptitude, Trust, Relevance and Satisfaction that affect two dependent and latent constructs, the Citizen Perception and the Citizen Expectative towards its relationship with the Public Administration through the use of Information and Communication Technologies - ICT, under the effect of illustrative variables related with citizen, institutions and context.

Foresight as an e-Government Development Planning Component: Proposed e-Government Foresight Framework

Directory of Open Access Journals (Sweden)

Rokas Grincevičius

2012-07-01

Full Text Available Despite the fact that e-government is developed by a country which is making the first steps in this area, or state, seeking to increase effectiveness of the existing e-government tools, it is necessary to have the methodology to create a basis for the formation of strategic e-government decisions, whose implementation will meet existing citizen needs and emerged challenges which appear during continuous information communication technology transformation processes.One of the ways to respond to these requirements is the application of foresight exercises as a component of strategic e-government planning. Nevertheless in Lithuania and many other Eastern European countries, the planning process is still centralized, based on the five-year planning context. Ex communist states are behind other regions with the number of research based on the foresight methodology, so these conditions determine the lack of information in this domain and this article is a small part of the attempt to fill the existing vacuum.The main aim of this article is to analyse the foresight impact on the electronic government strategic planning process, its role in the political decision formation process and by identifying contact points of different foresight research components, in the context of e-government foresight methodology framework creation processes, to form a deeper perception on how foresight works as a system.This aim is determined by the following objectives—to analyse foresight concept, circumstances and causes of its origin, main guidelines, methods used during foresight exercises and reasons, which determine its application; also, to analyse different suggested foresight exercise approaches and according to the results of the analysis, to form a distinctive e-government foresight methodology, which can be used for already performed foresight analysis or for prototyping a planned one.Thus, the first part of the article covers the most important theoretical

Here, I review the principles and applications of phase-contrast electron microscopy using phase plates. First, I develop the principle of phase contrast based on a minimal model of microscopy, introducing a double Fourier-transform process to mathematically formulate the image formation. Next, I explain four phase-contrast (PC) schemes, defocus PC, Zernike PC, Hilbert differential contrast, and schlieren optics, as image-filtering processes in the context of the minimal model, with particular emphases on the Zernike PC and corresponding Zernike phase plates. Finally, I review applications of Zernike PC cryo-electron microscopy to biological systems such as protein molecules, virus particles, and cells, including single-particle analysis to delineate three-dimensional (3D) structures of protein and virus particles and cryo-electron tomography to reconstruct 3D images of complex protein systems and cells.

Recent interest in flexible electronics has led to a paradigm shift in consumer electronics, and the emergent development of stretchable and wearable electronics is opening a new spectrum of ubiquitous applications for electronics. Organic electronic materials, such as π-conjugated small molecules and polymers, are highly suitable for use in low-cost wearable electronic devices, and their charge-carrier mobilities have now exceeded that of amorphous silicon. However, their commercialization is minimal, mainly because of weaknesses in terms of operational stability, long-term stability under ambient conditions, and chemical stability related to fabrication processes. Recently, however, many attempts have been made to overcome such instabilities of organic electronic materials. Here, an overview is provided of the strategies developed for environmentally robust organic electronics to overcome the detrimental effects of various critical factors such as oxygen, water, chemicals, heat, and light. Additionally, molecular design approaches to π-conjugated small molecules and polymers that are highly stable under ambient and harsh conditions are explored; such materials will circumvent the need for encapsulation and provide a greater degree of freedom using simple solution-based device-fabrication techniques. Applications that are made possible through these strategies are highlighted. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Shaikh, Sohail F.

2017-01-17

The state-of-the-art electronics technology has been an integral part of modern advances. The prevalent rise of the mobile device and computational technology in the age of information technology offers exciting applications that are attributed to sophisticated, enormously reliable, and most mature CMOS-based electronics. We are accustomed to high performance, cost-effective, multifunctional, and energy-efficient scaled electronics. However, they are rigid, bulky, and brittle. The convolution of flexibility and stretchability in electronics for emerging Internet of Everything application can unleash smart application horizon in unexplored areas, such as robotics, healthcare, smart cities, transport, and entertainment systems. While flexible and stretchable device themes are being remarkably chased, the realization of the fully compliant electronic system is unaddressed. Integration of data processing, storage, communication, and energy management devices complements a compliant system. Here, a comprehensive review is presented on necessity and design criteria for freeform (physically flexible and stretchable) compliant high-performance CMOS electronic systems.

Mohamed Mahmoud Nasef

2004-01-01

Membranes have generated considerable interest in a number of technologically significant fields, such as chemical, biochemical and biomedical engineering. However, it becomes important to design and develop particular membranes for specific applications. Radiation induced grafting of hydrophilic monomers into polymeric films has been found to be an appealing method for producing various membranes. The method has the flexibility of using various types of radiation, such as γ-rays, electron beam, and plasma, irrespective of the shape and size of the polymer. Of all, electron beam accelerator is an advantageous source of high-energy radiations that can initiate grafting reactions required for preparation of membranes particularly when pilot production and commercial applications are sought. The grafting penetration can be varied from surface to bulk of membranes by applying acceleration energy. This article briefly reviews the use of electron beam radiation to prepare various membranes by radiation induced grafting of vinyl and acrylic monomers onto polymer films. Some basic fundamentals of radiation induced grafting and advantages of electron beam over Co-60 are highlighted. Potential applications of radiation-grafted membranes in various fields are also surveyed. (author)

This is a presentation on high-power electron accelerators for space and other applications. The main points covered are: electron beams for space applications, new designs of RF accelerators, high-power high-electron mobility transistors (HEMT) testing, and Li-ion battery design. In summary, the authors have considered a concept of 1-MeV electron accelerator that can operate up to several seconds. This concept can be extended to higher energy to produce higher beam power. Going to higher beam energy requires adding more cavities and solid-state HEMT RF power devices. The commercial HEMT have been tested for frequency response and RF output power (up to 420 W). Finally, the authors are testing these HEMT into a resonant load and planning for an electron beam test in FY17.

GOVERNANCE ON THE INTERNET. MEASURING THE PERFORMANCES OF E-GOVERNANCE IN BUCHAREST MUNICIPALITIES

Directory of Open Access Journals (Sweden)

ANDREI ELVADEANU

2011-04-01

Full Text Available This paper analyzes the electronic governance and how it’s functioning in Romania. Being part of a larger institutional reform process, the electronic governance represents a new approach of the relation between Government and the citizen, with the purpose of increasing the participative dimension of the politic action, and as a way to provide more efficient services by the public agencies. E-governance uses information technologies (especially the Internet in the public sector, in order to improve the activity of bureaucratic institutions and encourage citizen participation. This paper analyzes the concept of electronic governance and with a focus on the obvious differences between the ideal model and the way in which these policies are actually implemented in Romania. The analysis was made for the 6 town-halls in Bucharest, but can offer a good sample of how egovernance is made in Romania. The instrument used for measurements is the comprehensive Rutgers egovernance performance index, covered in detail in the article. The areas taken into consideration were the public services offered by the institutions, the usage degree by the citizens and the civic participation dimension, understood as a bi-directional communication between the institutions and the citizen. The final part of the paper is dedicated to explaining the results, with recommendations for the Romanian public institutions. The research has its limits, but the results can draw attention over an institutional process that can represent a huge positive change in the way that governance is usually understood to be made in Romania and a very important improvement in the relation between state and society.

2010-02-01

Full Text Available Nanocomposites made up of polymer matrices and carbon nanotubes are a class of advanced materials with great application potential in electronics packaging. Nanocomposites with carbon nanotubes as fillers have been designed with the aim of exploiting the high thermal, electrical and mechanical properties characteristic of carbon nanotubes. Heat dissipation in electronic devices requires interface materials with high thermal conductivity. Here, current developments and challenges in the application of nanotubes as fillers in polymer matrices are explored. The blending together of nanotubes and polymers result in what are known as nanocomposites. Among the most pressing current issues related to nanocomposite fabrication are (i dispersion of carbon nanotubes in the polymer host, (ii carbon nanotube-polymer interaction and the nature of the interface, and (iii alignment of carbon nanotubes in a polymer matrix. These issues are believed to be directly related to the electrical and thermal performance of nanocomposites. The recent progress in the fabrication of nanocomposites with carbon nanotubes as fillers and their potential application in electronics packaging as thermal interface materials is also reported.

Applications of time-dependent Raman scattering theory to the one-electron reduction of 4-cyano-n-methylpyridinium

International Nuclear Information System (INIS)

Johnson, C.S.

1992-01-01

Activation barrier heights, and therefore rates, for molecule-based electron-transfer (ET) reactions are governed by redox thermodynamics and Frank-Condon effects. Quantitative assessment of the latter requires a detailed, quantitative knowledge of all internal and external normal-coordinate displacements, together with appropriate vibrational frequencies (v) or force constants (f). In favorable cases, the desire internal or vibrational displacement information can be satisfactorily estimated from redox-induced bond-length changes as provided, for example, by x-ray crystallography or extended x-ray absorption fine structure (EXAFS) measurements. Other potentially useful methods include Franck-Condon analysis of structured emission or absorption spectra, hole burning techniques, and application of empirical structure/frequency relationships (E.g., Badger's rules). There are, however, a number of limitations. The most obvious limitations for crystallography are that measurements can be made only in a crystalline environment and that experiments cannot be done on short-lived electron-transfer excited states or on systems which suffer from chemical decomposition following oxidation or reduction. For EXAFS there are additional constrains in that only selected elements display useful scattering and only atoms in close proximity to the scattering center may be detected. This report contains the first successful applications of the Raman methodology to a much larger class of ET reactions, namely, outer-sphere reactions. The report also necessarily represents the first application to a monomeric redox system

Applications of electron linacs to ADS: one potential path forward

International Nuclear Information System (INIS)

Wells, D.P.; Harmon, J.F.

2011-01-01

The application of electron linac accelerators to ADS systems offers a number of advantages for ADS applications. We propose a path forward with electron linac-driven ADS that takes advantage of those important ADS applications that are most easily achieved at relatively low cost, and then building on those successes to enable the more difficult applications with larger impact. We argue that the applications that are most easily achieved are medical isotope production, materials irradiation and environmental applications. The accelerator and target demands for each of these applications are essentially the same as for the ADS needs in energy production and the transmutation of waste. The successful demonstration of these important and highly-visible applications will, in turn, lead to greater visibility and funding to further major advances of ADS systems in energy production, nuclear waste transmutation, and applications to the thorium fuel cycle.

Full Text Available Electronic noses are customized devices employed to detect and to identify gaseous mixtures, even to give the concentration of the atmosphere components. Nowadays, the research in this domain is more and more growing, in Europe and other countries in the world, for many applications, such as environmental protection, food industries, perfumery, public safety, medicine, and pharmacy. Electronic noses allow to detect many organic volatile compounds, for which there is no specific detector. They constitute an alternative to complex, long, and too expensive existing methods, unable to ensure continuous monitoring. Their conception deals with many related areas (metrology, chemistry, physics, electronics, informatics, statistics, modelisation as well as areas related to the molecules to be detected. The system training is a primary step: during a measurement under a gaseous atmosphere, we must record the sensor time-responses in a treatment system, while specifying the name of the concerned odor. This process must be repeated many times for each studied atmosphere, and for all the chosen atmospheres. So a learning data base can be created, made from representative parameters of all the realized measures. After this training stage, clustering software will classify the data analysis in “concentration” or “nature” groups. Using the group separation rules given by this supervised classification, the system will be able to find itself the name of an odor or a concentration.

Four years ago, the first commercial installation of an electron beam processor, coupled with a high speed web offset printing press was described. This line has been in operation since and its success demonstrates the advantages and feasibility of such an application. Just recently, another company has announced that it is using electron beam curing in its printing lines. Judging from the amount of inquiries and opportunities being actively pursued one can state that the use of electron beam systems in printing applications has come of age. This paper describes the advantages of this process, the characteristics of the equipment that are important for industrial use in a multishift environment, and addresses its economics through analysis of some major cost elements

Who governs energy? The challenges facing global energy governance

International Nuclear Information System (INIS)

Florini, Ann; Sovacool, Benjamin K.

2009-01-01

This article conceptualizes the energy problems facing society from a global governance perspective. It argues that a notion of 'global energy governance,' taken to mean international collective action efforts undertaken to manage and distribute energy resources and provide energy services, offers a meaningful and useful framework for assessing energy-related challenges. The article begins by exploring the concepts of governance, global governance, and global energy governance. It then examines some of the existing institutions in place to establish and carry out rules and norms governing global energy problems and describes the range of institutional design options available to policymakers. It briefly traces the role of a selection of these institutions, from inter-governmental organizations to summit processes to multilateral development banks to global action networks, in responding to energy issues, and points out their strengths and weaknesses. The article concludes by analyzing how the various approaches to global governance differ in their applicability to addressing the conundrums of global energy problems.

Machi, Sueo

2011-02-01

Electron beam (EB) accelerators are major pieces of industrial equipment used for many commercial radiation processing applications. The industrial use of EB accelerators has a history of more than 50 years and is still growing in terms of both its economic scale and new applications. Major applications involve the modification of polymeric materials to create value-added products, such as heat-resistant wires, heat-shrinkable sheets, automobile tires, foamed plastics, battery separators and hydrogel wound dressing. The surface curing of coatings and printing inks is a growing application for low energy electron accelerators, resulting in an environmentally friendly and an energy-saving process. Recently there has been the acceptance of the use of EB accelerators in lieu of the radioactive isotope cobalt-60 as a source for sterilizing disposable medical products. Environmental protection by the use of EB accelerators is a new and important field of application. A commercial plant for the cleaning flue gases from a coal-burning power plant is in operation in Poland, employing high power EB accelerators. In Korea, a commercial plant uses EB to clean waste water from a dye factory.

Calculations of secondary electron yield of graphene coated copper for vacuum electronic applications

Directory of Open Access Journals (Sweden)

H. K. A. Nguyen

2018-01-01

Full Text Available The suppression of secondary electron yield (SEY which can possibly lead to multipactor is an important goal for several applications. Though some techniques have focused on geometric modifications to lower the SEY, the use of graphene coatings as thin as a few monolayers is a promising new development that deserves attention either as a standalone technique or in concert with geometric alterations. Here we report on Monte Carlo based numerical studies of SEY on graphene coated copper with comparisons to recent experimental data. Our predicted values are generally in good agreement with reported measurements. Suppression of the secondary electron yield by as much as 50 percent (over copper with graphene coating is predicted at energies below 125 eV, and bodes well for multipactor suppression in radio frequency applications.

We report a systematic treatment of the holographic generation of electron Bessel beams, with a view to applications in electron microscopy. We describe in detail the theory underlying hologram patterning, as well as the actual electron-optical configuration used experimentally. We show that by optimizing our nanofabrication recipe, electron Bessel beams can be generated with relative efficiencies reaching 37±3%. We also demonstrate by tuning various hologram parameters that electron Bessel beams can be produced with many visible rings, making them ideal for interferometric applications, or in more highly localized forms with fewer rings, more suitable for imaging. We describe the settings required to tune beam localization in this way, and explore beam and hologram configurations that allow the convergences and topological charges of electron Bessel beams to be controlled. We also characterize the phase structure of the Bessel beams generated with our technique, using a simulation procedure that accounts for imperfections in the hologram manufacturing process. - Highlights: • Bessel beams with different convergence, topological charge, visible fringes are demonstrated. • The relation between the Fresnel hologram and the probe shape is explained by detailed calculations and experiments. • Among the holograms here presented the highest relative efficiency is 37%, the best result ever reached for blazed holograms.

Photon and electron interaction databases and their use in medical applications

International Nuclear Information System (INIS)

Cullen, D.E.

1994-05-01

This paper discusses the All Particle-Method photon and electron interaction, and atomic relaxation data bases, that were initially developed for use in medical applications. Currently these data bases are being used in both medical and industrial applications. The All Particle Method data bases are designed to allow modelling of individual collisions in as much detail as possible. Elastic scattering can be modelled as single, as opposed to multiple, scattering events. Ionization can be modelled at the atomic subshell level, to define which subshell was ionized, spectrum of the initially emitted electron, as well as the spectra of electron and photons emitted as the atom relaxes back to neutrality. These data bases are currently being used in applications involving rather small spatial regions, where detailed calculations of individual events are required. While initially designed for use in medical applications, these data bases are now being used in a variety of industrial applications, e.g., transport in microelectronics

Applications of electron beam technology for healthcare and environment

Radiation technology has matured from lab scale to industrial scale in many areas of interests to industry, healthcare, agriculture and environment. Some of the well established applications include radiation sterilization, wires and cable, composites for automobiles, radiation surface curing, nanomaterials, hydrogels and special materials for nuclear and aerospace industry, radiation treatment of effluents, sewage sludge etc. These applications are as a result of characteristics of high energy radiation like gamma and electron beams which are able to deliver energy directly at molecular level. Unlike nuclear based radiations, electron beam accelerator technology is amenable to easy acceptance by public as well has capability to manipulate processes and product treatment to produce varieties of advanced/smart materials for healthcare and environment. Faster dose rates and depth profiling are the important characteristics of electron beam technology which gives it an edge over gamma radiation processing. Department of Atomic Energy has an ambitious program to indigenously develop accelerator technology and utilize them for national progress. In the presentation some important applications of radiation technology will be discussed. (author)

Improving ICT Governance by Reorganizing Operation of ICT and Software Applications: The First Step to Outsource

Science.gov (United States)

Johansson, Björn

During recent years great attention has been paid to outsourcing as well as to the reverse, insourcing (Dibbern et al., 2004). There has been a strong focus on how the management of software applications and information and communication technology (ICT), expressed as ICT management versus ICT governance, should be carried out (Grembergen, 2004). The maintenance and operation of software applications and ICT use a lot of the resources spent on ICT in organizations today (Bearingpoint, 2004), and managers are asked to increase the business benefits of these investments (Weill & Ross, 2004). That is, they are asked to improve the usage of ICT and to develop new business critical solutions supported by ICT. It also means that investments in ICT and software applications need to be shown to be worthwhile. Basically there are two considerations to take into account with ICT usage: cost reduction and improving business value. How the governance and management of ICT and software applications are organized is important. This means that the improvement of the control of maintenance and operation may be of interest to executives of organizations. It can be stated that usage is dependent on how it is organized. So, if an increase of ICT governance is the same as having well-organized ICT resources, could this be seen as the first step in organizations striving for external provision of ICT? This question is dealt with to some degree in this paper.

Environmental applications of electron-beam technology

International Nuclear Information System (INIS)

Pikaev, A.K.

2001-01-01

The main directions of modern environmental applications of electron-beam technology are the following: 1) treatment of polluted natural and drinking water, municipal and industrial wastewater, other liquid wastes; 2) purification of gases; 3) treatment of sewage sludges; 4) treatment of solid wastes (medical wastes, contaminated soil and so on). In some cases, the results of respective researches and developments found a large-scale application. For example, recently several industrial plants for electron-beam purification of flue gases of thermal power plants from SO2 and NOx were created in China, Poland and Japan. In the report, a brief summary of the most important results obtained in the mentioned directions will be presented. A special attention will be paid to the data in the first direction. In particular, the recent results on radiation treatment of some liquid systems obtained in the laboratory under author's leadership will be considered. One of them is water polluted with petroleum products (motor oil, diesel fuel, residual fuel oil). The pollutants were present in water in dissolved form and as a separate phase. It was found that irradiation (dose 25-40 kGy) decomposes and removes the pollutants as a precipitate. The second system is natural oil gas consisting of gaseous and low-boiling hydrocarbons, water and so on. Laboratory- and pilot-scale (with electron accelerator of 0.7 MeV and 30 kW) studies have shown that electron-beam treatment (in a recycling regime with continuous sampling the liquid phase) of this gas leads to the formation of a mixture of liquid branched hydrocarbons, alcohols, ethers and so on, i.e., there is a radiation-induced liquefaction of the natural oil gas. The mechanism of radiolytic conversions occurring in the mentioned systems will be discussed

Graphene Inks with Cellulosic Dispersants: Development and Applications for Printed Electronics

Science.gov (United States)

Secor, Ethan Benjamin

Graphene offers promising opportunities for applications in printed and flexible electronic devices due to its high electrical and thermal conductivity, mechanical flexibility and strength, and chemical and environmental stability. However, scalable production and processing of graphene presents a critical technological challenge preventing the application of graphene for flexible electronic interconnects, electrochemical energy storage, and chemically robust electrical contacts. In this thesis, a promising and versatile platform for the production, patterning, and application of graphene inks is presented based on cellulosic dispersants. Graphene is produced from flake graphite using scalable liquid-phase exfoliation methods, using the polymers ethyl cellulose and nitrocellulose as multifunctional dispersing agents. These cellulose derivatives offer high colloidal stability and broadly tunable rheology for graphene dispersions, providing an effective and tunable platform for graphene ink development. Thermal or photonic annealing decomposes the polymer dispersant to yield high conductivity, flexible graphene patterns for various electronics applications. In particular, the chemical stability of graphene enables robust electrical contacts for ceramic, metallic, organic and electrolytic materials, validating the diverse applicability of graphene in printed electronics. Overall, the strategy for graphene ink design presented here offers a simple, efficient, and versatile method for integrating graphene in a wide range of printed devices and systems, providing both fundamental insight for nanomaterial ink development and realistic opportunities for practical applications.

Deployment of German Electronic Citizen Cards in Banking: Opportunities and Challenges

Science.gov (United States)

Büger, Matthias

The German federal government plans to issue an electronic citizen card (eID) in 2009, replacing the current identity card (Personalausweis). Since the eID should be good for identification in E-government as well as E-business applications, it is aimed to be used in the banking environment. One application would be opening a bank account in the internet. If this was possible, the process would be much easier than today. However, German law still requires a physical ID card. We will discuss the opportunities and the challenges of possible usage of eID in banking.

Electron holography-basics and applications

International Nuclear Information System (INIS)

Lichte, Hannes; Lehmann, Michael

2008-01-01

Despite the huge progress achieved recently by means of the corrector for aberrations, allowing now a true atomic resolution of 0.1 nm, hence making it an unrivalled tool for nanoscience, transmission electron microscopy (TEM) suffers from a severe drawback: in a conventional electron micrograph only a poor phase contrast can be achieved, i.e. phase structures are virtually invisible. Therefore, conventional TEM is nearly blind for electric and magnetic fields, which are pure phase objects. Since such fields provoked by the atomic structure, e.g. of semiconductors and ferroelectrics, largely determine the solid state properties, hence the importance for high technology applications, substantial object information is missing. Electron holography in TEM offers the solution: by superposition with a coherent reference wave, a hologram is recorded, from which the image wave can be completely reconstructed by amplitude and phase. Now the object is displayed quantitatively in two separate images: one representing the amplitude, the other the phase. From the phase image, electric and magnetic fields can be determined quantitatively in the range from micrometre down to atomic dimensions by all wave optical methods that one can think of, both in real space and in Fourier space. Electron holography is pure wave optics. Therefore, we discuss the basics of coherence and interference, the implementation into a TEM, the path of rays for recording holograms as well as the limits in lateral and signal resolution. We outline the methods of reconstructing the wave by numerical image processing and procedures for extracting the object properties of interest. Furthermore, we present a broad spectrum of applications both at mesoscopic and atomic dimensions. This paper gives an overview of the state of the art pointing at the needs for further development. It is also meant as encouragement for those who refrain from holography, thinking that it can only be performed by specialists in

Chemical Vapor-Deposited (CVD) Diamond Films for Electronic Applications

Science.gov (United States)

1995-01-01

Diamond films have a variety of useful applications as electron emitters in devices such as magnetrons, electron multipliers, displays, and sensors. Secondary electron emission is the effect in which electrons are emitted from the near surface of a material because of energetic incident electrons. The total secondary yield coefficient, which is the ratio of the number of secondary electrons to the number of incident electrons, generally ranges from 2 to 4 for most materials used in such applications. It was discovered recently at the NASA Lewis Research Center that chemical vapor-deposited (CVD) diamond films have very high secondary electron yields, particularly when they are coated with thin layers of CsI. For CsI-coated diamond films, the total secondary yield coefficient can exceed 60. In addition, diamond films exhibit field emission at fields orders of magnitude lower than for existing state-of-the-art emitters. Present state-of-the-art microfabricated field emitters generally require applied fields above 5x10^7 V/cm. Research on field emission from CVD diamond and high-pressure, high-temperature diamond has shown that field emission can be obtained at fields as low as 2x10^4 V/cm. It has also been shown that thin layers of metals, such as gold, and of alkali halides, such as CsI, can significantly increase field emission and stability. Emitters with nanometer-scale lithography will be able to obtain high-current densities with voltages on the order of only 10 to 15 V.

Full Text Available Local governments (LGs have an important role in providing services to the community. Nevertheless, some local governments still show relatively low performance. Scores of e-government implementation and audit opinions obtained by some local governments are also relatively low. This study examines whether there are relationships between e-government, the dimensions of e-government, and audit opinion and the performance of the local government administration. There are five dimensions of the e-government i.e. policy, institutions, infrastructure, applications, and planning. The sample used in this study includes 246 local governments from 2012 to 2014. Using regression analysis, the results of this study show that e-government has a positive association with the performance of the local government administration. This is supported by the positive association of e-government’s dimensions with performance. The audit opinion is also positively associated with performance as expected. These results suggest that e-government and audit opinion can be used as indicators of the performance of local government administration.

2004-01-01

Linear accelerators (linac) were introduced into the Kingdom of Thailand almost twenty years ago. They were installed at major hospitals around the country for radiotherapy. At present there are 20 medical electron linacs in Thailand. Three of the new linacs are recently installed at Chiang Mai University Hospital. The first industrial electron accelerator was commissioned in 1997 for sterilization of medical products such as doctor gown, pampas etc. for export. It has accelerating voltage in the range between 1.8 to 2.4 MeV and power of 10 kW. The second electron accelerator was introduced in the year 2000 for gemstone enhancement. This one is a 15 MeV, 8.5 kW electron linac. Since 2000 a program to generate electron beams for research and industrial application has been realized at Chiang Mai University. Both high (10-30 MeV) and low (300 keV) energy electron accelerating systems are being explored. Here we describe the present development status and near future applications. (author)

GaN Based Electronics And Their Applications

Ren, Fan

2002-03-01

The Group III-nitrides were initially researched for their promise to fill the void for a blue solid state light emitter. Electronic devices from III-nitrides have been a more recent phenomenon. The thermal conductivity of GaN is three times that of GaAs. For high power or high temperature applications, good thermal conductivity is imperative for heat removal or sustained operation at elevated temperatures. The development of III-N and other wide bandgap technologies for high temperature applications will likely take place at the expense of competing technologies, such as silicon-on-insulator (SOI), at moderate temperatures. At higher temperatures (>300°C), novel devices and components will become possible. The automotive industry will likely be one of the largest markets for such high temperature electronics. One of the most noteworthy advantages for III-N materials over other wide bandgap semiconductors is the availability of AlGaN/GaN and InGaN/GaN heterostructures. A 2-dimensional electron gas (2DEG) has been shown to exist at the AlGaN/GaN interface, and heterostructure field effect transistors (HFETs) from these materials can exhibit 2DEG mobilities approaching 2000 cm2 / V?s at 300K. Power handling capabilities of 12 W/mm appear feasible, and extraordinary large signal performance has already been demonstrated, with a current state-of-the-art of >10W/mm at X-band. In this talk, high speed and high temperature AlGaN/GaN HEMTs as well as MOSHEMTs, high breakdown voltage GaN (>6KV) and AlGaN (9.7 KV) Schottky diodes, and their applications will be presented.

Potential ceramics processing applications with high-energy electron beams

International Nuclear Information System (INIS)

Struve, K.W.; Turman, B.N.

1993-01-01

High-energy, high-current electron beams may offer unique features for processing of ceramics that are not available with any other heat source. These include the capability to instantaneously heat to several centimeters in depth, to preferentially deposit energy in dense, high-z materials, to process at atmospheric pressures in air or other gases, to have large control over heating volume and heating rate, and to have efficient energy conversion. At a recent workshop organized by the authors to explore opportunities for electron beam processing of ceramics, several applications were identified for further development. These were ceramic joining, fabrication of ceramic powders, and surface processing of ceramics. It may be possible to join ceramics by either electron-beam brazing or welding. Brazing with refractory metals might also be feasible. The primary concern for brazing is whether the braze material can wet to the ceramic when rapidly heated by an electron beam. Raw ceramic powders, such as silicon nitride and aluminum nitride, which are difficult to produce by conventional techniques, could possibly be produced by vaporizing metals in a nitrogen atmosphere. Experiments need to be done to verify that the vaporized metal can fully react with the nitrogen. By adjusting beam parameters, high-energy beams can be used to remove surface flaws which are often sites of fracture initiation. They can also be used for surface cleaning. The advantage of electron beams rather than ion beams for this application is that the heat deposition can be graded into the material. The authors will discuss the capabilities of beams from existing machines for these applications and discuss planned experiments

Full Text Available The last decade has changed again the face of electronic world: from Web 2.0 to open source software; from e-(electronic to m-(mobile and now to touch. For Web developers is a real challenge to make compatible interfaces to all existing Internet browsers. This proves to be even more expensive than the application itself (Softnet; 2012; SIVECO, 2012. From the point of view of the big software development companies these events are just new challenges because they afford to have many employees with different skills and by that being able to cope with market demands. But what happens with the e-government projects at the local level? Budgets are small, so hiring a company specialized in Web application development is sometimes too expensive, this responsibility usually falls in many cases on the employees of the IT department (Vrabie, 2011. If we add to this software component the hardware required for hosting the Web page inside, the budgets are already completely exceeded (or obviously they can choose some other cheap solution but whose reliability is very poor – reason for dissatisfaction among citizens. The importance of the Web platforms for interacting with citizens is very well known (Friedman, 2005; Craig; 2006; Baltac, 2011. In this context, this paper aims to examine in terms of costs, the investments in open-source applications in parallel with the use of social networks as used today. The research methodology is using for the first time an adapted version of cost-effectiveness analysis. Empirical research will be carried out on two platforms of e-Government – one of them developed inside on an open-source solution - used to support a complete interaction with the citizens. The working hypothesis starts from the fact that open source software is cheaper than those developed inside – but of course this is a question to debate at.

Full Text Available This article presents an overview on typical properties, technologies, and applications of liquid metal based flexible printed electronics. The core manufacturing material—room-temperature liquid metal, currently mainly represented by gallium and its alloys with the properties of excellent resistivity, enormous bendability, low adhesion, and large surface tension, was focused on in particular. In addition, a series of recently developed printing technologies spanning from personal electronic circuit printing (direct painting or writing, mechanical system printing, mask layer based printing, high-resolution nanoimprinting, etc. to 3D room temperature liquid metal printing is comprehensively reviewed. Applications of these planar or three-dimensional printing technologies and the related liquid metal alloy inks in making flexible electronics, such as electronical components, health care sensors, and other functional devices were discussed. The significantly different adhesions of liquid metal inks on various substrates under different oxidation degrees, weakness of circuits, difficulty of fabricating high-accuracy devices, and low rate of good product—all of which are challenges faced by current liquid metal flexible printed electronics—are discussed. Prospects for liquid metal flexible printed electronics to develop ending user electronics and more extensive applications in the future are given.

2013-12-01

Full Text Available This study is designed to assess the mediating effect of the Service Quality in shaping the experience of users of e-Government applications. Users normally evaluate their satisfaction in using technological innovation such as e-Government from their direct and indirect involvement and the perceived value of the system in question. To study the mediation effect, a self-administered questionnaire based on a tested model is used to collect the experience of users of recently implemented e-Government applications in the public sector in Saudi Arabia. Data was gathered from 208 internal respondents and then analyzed using structural equation modeling (SEM. Different mediation models were tested and evaluated using common standard SEM parameters. The results showed that the value perceived from the System Quality and Information Quality does impact the User Satisfaction, but Service Quality was found to play a stronger role in mediating the relationship between User Satisfaction and both the System Quality and Information Quality. The degree and direction of this mediation were analyzed and interpreted from the user and the technical support perspectives. The study compares these findings with those from earlier studies using similar models.

Monte Carlo calculation of scattered radiation from applicators in low energy clinical electron beams

International Nuclear Information System (INIS)

Jabbari, N.; Hashemi-Malayeri, B.; Farajollahi, A. R.; Kazemnejad, A.

2007-01-01

In radiotherapy with electron beams, scattered radiation from an electron applicator influences the dose distribution in the patient. The contribution of this radiation to the patient dose is significant, even in modern accelerators. In most of radiotherapy treatment planning systems, this component is not explicitly included. In addition, the scattered radiation produced by applicators varies based on the applicator design as well as the field size and distance from the applicators. The aim of this study was to calculate the amount of scattered dose contribution from applicators. We also tried to provide an extensive set of calculated data that could be used as input or benchmark data for advanced treatment planning systems that use Monte Carlo algorithms for dose distribution calculations. Electron beams produced by a NEPTUN 10PC medical linac were modeled using the BEAMnrc system. Central axis depth dose curves of the electron beams were measured and calculated, with and without the applicators in place, for different field sizes and energies. The scattered radiation from the applicators was determined by subtracting the central axis depth dose curves obtained without the applicators from that with the applicator. The results of this study indicated that the scattered radiation from the electron applicators of the NEPTUN 10PC is significant and cannot be neglected in advanced treatment planning systems. Furthermore, our results showed that the scattered radiation depends on the field size and decreases almost linearly with depth. (author)

This study aims to determine the level and extent of usage of electronic health records (EHRs) in government-related hospitals in Eastern Province, Saudi Arabia. Another aim is to develop a Web site to serve as a forum of exchange on the development of EHRs in Saudi Arabia. All government hospitals (n = 19) in the province were included. The information technology (IT) managers in those hospitals made up the target population. An online questionnaire was developed, and the IT managers in all 19 government hospitals were invited to participate in the survey. The responses from the online survey were downloaded and analyzed using descriptive statistics. Of the 19 hospitals, only three (15.8 percent) use EHRs. These hospitals were established in 1984, 1995, and 2005. All three of these hospitals have implemented the same EHR software and were using it successfully, and all three were using the three core features of laboratory, radiology, and pharmacy electronic modules. Some modules were present in the EHR system but were underutilized. Some of the main challenges faced by the IT managers in implementing EHRs in their hospitals were related to the uncooperative attitudes of some physicians and nurses toward EHRs. In fulfillment of the second aim of the study, a Web site, http://ehr2011.weebly.com, was developed to serve as a forum for exchange of information on the development of EHRs in Saudi Arabia. The government of Saudi Arabia has prioritized the development of eHealth (health information technology) and allocated committed funding for it during 2008-2011. During this period, some sectors of government made highly commendable efforts in developing eHealth services. Along these lines, we had hoped to see higher uptake of EHRs than the 15.8 percent found in this study. The rate of implementing EHRs in government hospitals should be accelerated. The aim should be on achieving some basic EHR functionality in these hospitals, and once this has been achieved

CMOS technology: a critical enabler for free-form electronics-based killer applications

Science.gov (United States)

Hussain, Muhammad M.; Hussain, Aftab M.; Hanna, Amir

2016-05-01

Complementary metal oxide semiconductor (CMOS) technology offers batch manufacturability by ultra-large-scaleintegration (ULSI) of high performance electronics with a performance/cost advantage and profound reliability. However, as of today their focus has been on rigid and bulky thin film based materials. Their applications have been limited to computation, communication, display and vehicular electronics. With the upcoming surge of Internet of Everything, we have critical opportunity to expand the world of electronics by bridging between CMOS technology and free form electronics which can be used as wearable, implantable and embedded form. The asymmetry of shape and softness of surface (skins) in natural living objects including human, other species, plants make them incompatible with the presently available uniformly shaped and rigidly structured today's CMOS electronics. But if we can break this barrier then we can use the physically free form electronics for applications like plant monitoring for expansion of agricultural productivity and quality, we can find monitoring and treatment focused consumer healthcare electronics - and many more creative applications. In our view, the fundamental challenge is to engage the mass users to materialize their creative ideas. Present form of electronics are too complex to understand, to work with and to use. By deploying game changing additive manufacturing, low-cost raw materials, transfer printing along with CMOS technology, we can potentially stick high quality CMOS electronics on any existing objects and embed such electronics into any future objects that will be made.

Electron accelerators and applications in Korea

International Nuclear Information System (INIS)

Han, Bumsoo

2006-01-01

Types of high-energy radiation were discovered more than one hundred years ago. Since then, properties of radiation providing ability to modify physico-chemical properties of materials have found many applications. Radiation technologies applying gamma sources as well as electron accelerators for treatment of materials are well-established processes. Worldwide, there are over 2000 industrial gamma irradiators and 1,300 industrial electron accelerators in operation that are being widely used for sterilization, food irradiation and polymer processing. Indeed, radiation processing is today a well established multi-billion dollar industry world over that is providing unique high value products for mankind in an environmentally friendly manner. Electron accelerators are introduced at late 70s in Korea, firstly for researches and later for insulated wire and cable production, and up to now, over 30 accelerators are used in industries. They are mainly for cable productions, thermo-shrinkable materials, foam sheets, coating and curing and others. While polymerization and polymer modification have proved to be the most widespread applications of radiation processing, many other applications, such as environmental protection is becoming an increasingly important concern in industrialized nations, and wide ranging investigations have identified several areas of waste control to which radiation processing may contribute. In recent years, large metropolitan cities including Seoul, Tokyo and other major cities have been facing the challenge of increasing environmental pollution resulting from ever increasing population and industrial activities. As a result, issues regarding environmental pollution, be it air, liquid or solid, are becoming significant matters of concern. The realization that such pollutants pose a serious threat to human health has necessitated the need for development of cost effective and environmentally friendly technologies to overcome the problem.

Wong, Y S

1982-01-01

Scanning Electron Microscopy - Energy Dispersive X-Ray Analysis (SEM/EDX) has been applied in casework for more than a year in the Forensic Division, Government Laboratory of Hong Kong. The types of samples being analysed are summarised and three cases of scientific interest are described. The first case applies SEM/EDX to characterize microscopic gold particles recovered from clothing of suspects involved in goldsmith robberies. Both elemental and morphological results obtained were used as supporting evidence. The second case describes the three types of beaded ends on fibres found in a single cloth sample. These beaded ends are different in shape and surface features and can be used as an additional parameter in fibre identification. The final case shows the application of vacuum evaporation of graphite on a document sample to reveal the area of paper which has been skillfully mechanically erased. Both the image intensity and the composition of the ink are used to differentiate between original and altered characters on the document.

Exo-electrons and initiation of electric discharges

Laube, Sylvain

1992-01-01

As some observations seemed to indicate that glass submitted to an electric field could be a source of electrons, and that any dielectric could play the role, this research thesis aimed at verifying this hypothesis, at least for two industrially used dielectrics (Teflon and Kapton). The author also shows the advantage which could be taken from such an emission, as well in the field of electric discharges as in the field of their applications. Electrons emitted in such conditions are herein called exo-electrons. In a first part, the author analysed the characteristic magnitudes which govern the conditions of discharge initiation, i.e. the initiation voltage and the statistic delay between the application of an electric field and the initiative occurrence. The second part presents the different measurements devices which have been designed, and the third part presents and discusses experimental results, and shows that the theoretical model is in compliance with initiation voltage measurements. As far as electron emission is concerned, a possible explication of this phenomenon is proposed [fr

Physical and temporal restrictions imposed by modern aeroballistics have pushed imaging technology to the point where special photoconductive surfaces and high-speed support electronics are dictated. Specifications for these devices can be formulated by a methodical analysis of critical parameters and how they interact. In terms of system theory, system transfer functions and state equations can be used in optimal coupling of devices to maximize system performance. Application of these methods to electronic imaging at the Eglin Aeroballistics Research Facility is described in this report. 7 references, 14 figures, 1 table

The advent of free electron lasers opens up new opportunities to probe the dynamics of ultrafast processes and the structure of matter with unprecedented spatial and temporal resolution. New methods inaccessible with other known types of radiation sources can be developed, resulting in a breakthrough in deep understanding the fundamentals of life as well as in numerous medical and biological applications. In the present work the properties of free electron laser radiation that make the sources excellent for probing biological matter at an arbitrary wavelength, in a wide range of intensities and pulse durations are briefly discussed. A number of biophysical and biomedical applications of the new sources, currently considered among the most promising in the field, are presented. (author)

CMOS technology: a critical enabler for free-form electronics-based killer applications

KAUST Repository

Hussain, Muhammad Mustafa

2016-05-17

Complementary metal oxide semiconductor (CMOS) technology offers batch manufacturability by ultra-large-scaleintegration (ULSI) of high performance electronics with a performance/cost advantage and profound reliability. However, as of today their focus has been on rigid and bulky thin film based materials. Their applications have been limited to computation, communication, display and vehicular electronics. With the upcoming surge of Internet of Everything, we have critical opportunity to expand the world of electronics by bridging between CMOS technology and free form electronics which can be used as wearable, implantable and embedded form. The asymmetry of shape and softness of surface (skins) in natural living objects including human, other species, plants make them incompatible with the presently available uniformly shaped and rigidly structured today’s CMOS electronics. But if we can break this barrier then we can use the physically free form electronics for applications like plant monitoring for expansion of agricultural productivity and quality, we can find monitoring and treatment focused consumer healthcare electronics – and many more creative applications. In our view, the fundamental challenge is to engage the mass users to materialize their creative ideas. Present form of electronics are too complex to understand, to work with and to use. By deploying game changing additive manufacturing, low-cost raw materials, transfer printing along with CMOS technology, we can potentially stick high quality CMOS electronics on any existing objects and embed such electronics into any future objects that will be made.

Koshiishi, Kenji

1989-01-01

Recently in the fields of home electric appliances, machinery and equipment and interior building materials, the needs for the precoated steel plates having the design and function of high class increase rapidly. In order to cope with such needs, the authors have advanced the examination on the application of electron beam hardening technology to precoated steel plates, and developed the precoated steel plates of high grade and high design 'Super Tecstar EB Series' by utilizing low energy electron beam. The features of this process are (1) hardening can be done at room temperature in a short time-thermally weak films can be adhered, (2) high energy irradiation-the hardening of thick enamel coating and the adhesion of colored films are feasible, (3) the use of monomers of low molecular weight-by high crosslinking, the performance of high sharpness, high hardness, anti-contamination property and so on can be given. The application to precoated steel plate production process is the coating and curing of electron beam hardening type paints, the coating of films with electron beam hardening type adhesives, and the reforming of surface polymer layers by impregnating monomers and causing graft polymerization with electron beam irradiation. The outline of the Super Tecstar EB Series is described. (K.I.)

1982-01-01

Electron beam welding process is efficient and is superior in workmanship and its application to the welding of large plate structures is eagerly awaited. However, since electron beam welding is generally performed with the object of welding entirely put in a vacuum chamber, high welding cost becomes a problem. In response to this demand, two kinds of local vacuum slide sealing type electron beam welding machines have been developed. These welding machines are designed to perform welding with only the neighborhood of the weld line put in vacuum, one of which is for longitudinal joints and the other for circumferential joints. The welding machine for circumferential joints has been put to practical use for the welding of nucear fusion reactor vacuum vessels (outside diameter 3.5 m, inside diameter 1.7 m), showing that it is applicable to the welding of large structures.

Convergence of Corporate and Public Governance

Full Text Available By analyzing the differences between the corporate and public governance, theoretical and empirical research seems to indicate that the two domains of governance are far too different to share any common aspect. However, in this particular research, it has been argued that public governance is an application of corporate governance. Thus, the research question entails the description and analysis of this possible convergence of the two. Extensive research from literature on corporate governance has been undertaken to establish a relationship between the boards process and the roles that acts as a framework to bridge the gap separating corporate governance from public governance. Corporate governance, at a global level, exists in the for-profit as well as nonprofit organizations. Thus, the definition of this concept needs to be viewed from “an innovative” eye, considering the relationship between the process of the board and roles as characteristic of the public organization and private ones. As the private as well as public organizations are an application of corporate governance, the difference between the two gets narrowed. For the purpose of this research, the case of the French hospitals’ board has been taken into consideration. The members of the public board have been considered for the board process to perform their roles.

Governance in Health - The Need for Exchange and Evidence Comment on "Governance, Government, and the Search for New Provider Models".

Science.gov (United States)

Chanturidze, Tata; Obermann, Konrad

2016-05-17

Governance in health is cited as one of the key factors in balancing the concerns of the government and public sector with the interests of civil society/private players, but often remains poorly described and operationalized. Richard Saltman and Antonio Duran look at two aspects in the search for new provider models in a context of health markets signalling liberalisation: (i) the role of the government to balance public and private interests and responsibilities in delivering care through modernised governance arrangements, and (ii) the finding that operational complexities may hinder well-designed provider governance models, unless governance reflects country-specific realities. This commentary builds on the discussion by Saltman and Duran, and argues that the concept of governance needs to be clearly defined and operationalized in order to be helpful for policy debate as well as for the development of an applicable framework for performance improvement. It provides a working definition of governance and includes a reflection on the prevailing cultural norms in an organization or society upon which any governance needs to be build. It proposes to explore whether the "evidence-based governance" concept can be introduced to generate knowledge about innovative and effective governance models, and concludes that studies similar to the one by Saltman and Duran can inform this debate. © 2016 by Kerman University of Medical Sciences.

As indicated by the results of this study, low energy electron beam accelerator of 200 keV to 500 keV can be utilized to irradiate thin hydrogel film in the range of 60 to 500 μm thickness. However, the industrial applications of this technology will depend on its applications. For thin films, cosmetic use such as faced mask is possible. The production of sago hydrogel for cosmetic used is in the process of commercialization in Malaysia. As for electron beam treatment of industrial wastewater in particular the effluent from the textile industry is still at infancy. Further work is necessary in order to have a base line data before the commercialization is taken place. Malaysia has also embarked on the electron beam treatment of flue gases and has completed the semi-pilot scale study by using 1.0 MeV electron accelerator voltage and 400 cum flue gas generated from diesel generator. This study was conducted together with the TNB Research, the research institute belongs to the electrical power company in Malaysia. For technology transfer and commercialization, MINT is planned to promote this technology to Independent Power Producers (IPP) in Malaysia. (author)

On the applicability of one- and many-electron quantum chemistry models for hydrated electron clusters

Science.gov (United States)

Turi, László

2016-04-01

We evaluate the applicability of a hierarchy of quantum models in characterizing the binding energy of excess electrons to water clusters. In particular, we calculate the vertical detachment energy of an excess electron from water cluster anions with methods that include one-electron pseudopotential calculations, density functional theory (DFT) based calculations, and ab initio quantum chemistry using MP2 and eom-EA-CCSD levels of theory. The examined clusters range from the smallest cluster size (n = 2) up to nearly nanosize clusters with n = 1000 molecules. The examined cluster configurations are extracted from mixed quantum-classical molecular dynamics trajectories of cluster anions with n = 1000 water molecules using two different one-electron pseudopotenial models. We find that while MP2 calculations with large diffuse basis set provide a reasonable description for the hydrated electron system, DFT methods should be used with precaution and only after careful benchmarking. Strictly tested one-electron psudopotentials can still be considered as reasonable alternatives to DFT methods, especially in large systems. The results of quantum chemistry calculations performed on configurations, that represent possible excess electron binding motifs in the clusters, appear to be consistent with the results using a cavity structure preferring one-electron pseudopotential for the hydrated electron, while they are in sharp disagreement with the structural predictions of a non-cavity model.

This paper is a roadmap to the exhaustive role of the newly emerging field of nanotechnology in various application and research areas. Some of the today's important topics are plasma, dielectric layer semiconductor, and carbon nanoparticle based technologies. Carbon nanotubes are very useful for the purpose of fabricating nano opto power devices. The basic concept behind tunneling of electrons has been utilized to define another scope of this technology, and thus came many quantum scale tunneling devices and elements. Fabrication of crystal semiconductors of high quality along with oxides of nano aspect would give rise to superior device performance and find applications such as LEDs, LASER, VLSI technology and also in highly efficient solar cells. Many nano-research based organizations are fully devoted to develop nano power cells, which would give birth to new battery cells, tunneling devises, with high power quality, longer lives, and higher activation rates. Different electronics industries as well as the military organizations would be largely benefited due to this major component and system design ideas of 'Smart Power' technologies. The contribution of nano scale power electronics would be realized in various fields like switching devices, electromechanical systems and quantum science. Such a sophisticated technology will have great impact on the modernization of robotics; space systems, automotive systems and many other fields. The highly emerging field of nanomedicine according to specialists would bring a dramatic revolution in the present century. However nanomedicine is nothing but an integration of biology, medicine and technology. Thermoelectric materials as been referred earlier also are used in case of implantable medical equipments for generation of electric power sufficient for those equipments.

2007-01-01

With the growing intelligence and popularity of mobile phones, and the trend of cellular network's convergence to IP based network, more and more mobile applications emerge on the market. For mission critical applications, like the electronic payment which will be discussed in this paper, the lack of trust in the underlying mobile infrastructure and secure interface to legacy systems (for this case, the banking systems) poses obstacles to their widespread presence in mobile services. Recently, the exposure of hacking of iPhone and other smart phones further emphasizes the criticality of establishing a trust platform for mobile applications. This paper analyzes the building blocks of the trusted smart phone, and proposes a framework to provide a trusted platform for mobile electronic payment. Such a proposed system may allow direct interface to the banking systems due to the banking industry recognized strong security, and hence, may enable its widespread use.

HIGH-CURRENT COLD CATHODE FIELD EMISSION ARRAY FOR ELECTRON LENS APPLICATION

Energy Technology Data Exchange (ETDEWEB)

Hirshfield, Jay L

2012-12-28

During Phase I, the following goals were achieved: (1) design and fabrication of a novel, nano-dimensional CNT field emitter assembly for high current density application, with high durability; (2) fabrication of a ceramic based micro channel plate (MCP) and characterization of its secondary electron emission; and (3) characterizing the CNT/MCP cathode for high field emission and durability. As a result of these achievements, a relatively high current density of ~ 1.2 A/cm2 from a CNT cathode and single channel MCP were measured. The emission current was also extremely stable with a peak-to-peak variation of only 1.8%. The emission current could be further enhanced to meet requirements for electron lens applications by increasing the number of MCP channels. A calculation for maximum possible current density with a 1200 channel/cm2 MCP, placed over a cathode with 1200 uniformly functioning CNTs, would be ~1.46 kA/cm2, neglecting space charge limitations. Clearly this level of emission is far greater than what is needed for the electron lens application, but it does offer a highly comforting margin to account for sub-standard emitters and/or to allow the lesser challenge of building a cathode with fewer channels/cm2. A satisfactory goal for the electron lens application would be a controllable emission of 2-4 mA per channel in an ensemble of 800-1200 uniformly-functioning channels/cm2, and a cathode with overall area of about 1 cm2.

CMOS-Technology-Enabled Flexible and Stretchable Electronics for Internet of Everything Applications

Hussain, Aftab M.

2015-11-26

Flexible and stretchable electronics can dramatically enhance the application of electronics for the emerging Internet of Everything applications where people, processes, data and devices will be integrated and connected, to augment quality of life. Using naturally flexible and stretchable polymeric substrates in combination with emerging organic and molecular materials, nanowires, nanoribbons, nanotubes, and 2D atomic crystal structured materials, significant progress has been made in the general area of such electronics. However, high volume manufacturing, reliability and performance per cost remain elusive goals for wide commercialization of these electronics. On the other hand, highly sophisticated but extremely reliable, batch-fabrication-capable and mature complementary metal oxide semiconductor (CMOS)-based technology has facilitated tremendous growth of today\\'s digital world using thin-film-based electronics; in particular, bulk monocrystalline silicon (100) which is used in most of the electronics existing today. However, one fundamental challenge is that state-of-the-art CMOS electronics are physically rigid and brittle. Therefore, in this work, how CMOS-technology-enabled flexible and stretchable electronics can be developed is discussed, with particular focus on bulk monocrystalline silicon (100). A comprehensive information base to realistically devise an integration strategy by rational design of materials, devices and processes for Internet of Everything electronics is offered. © 2015 WILEY-VCH Verlag GmbH & Co.

The use of stimulated electron emission (SEE) in homeland security applications

Science.gov (United States)

Ing, H.; Andrews, H. R.; Facina, M.; Lee, W. T.; Niu, H. W.

2012-06-01

Certain insulating solids can store a fraction of the absorbed energy when irradiated by ionizing radiation. The stored energy can be released subsequently by heating or optical stimulation. As a result, light may be emitted through Thermoluminescence (TL) or Optically-Stimulated Luminescence (OSL) and electrons may be emitted through Thermally-Stimulated Electron Emission (TSEE) or Optically-Stimulated Electron Emission (OSEE). TL and OSL are widely used in current radiation dosimetry systems. However, despite considerable research effort during the early 1970s, SEE was not commonly adopted for dosimetry applications. One of the main reasons is that SEE is a surface phenomenon, while luminescence is a bulk phenomenon, making SEE more susceptible to humidity, absorption of gases, minor physical defects and handling, both before and after irradiation. Nevertheless, it has been recognized that SEE may be useful for homeland security applications in nuclear forensics, where dose accuracy is not the primary performance metric. In this research, we are investigating the use of SEE for nuclear forensic applications. Many common materials, both natural and man-made, exhibit the phenomenon, providing an opportunity to use the environment itself as an in-situ radiation detector. We have designed and constructed a unique prototype reader for conducting SEE measurements. We have demonstrated that the SEE measurements from a variety of materials are quantitatively reproducible and correlated to radiation exposure. Due to the broad applicability of SEE, significant additional studies are warranted to optimize this novel technique for nuclear forensic and other applications.

2011-01-01

Full Text Available Remote rural areas are constrained by lack of reliable power supply, essential for setting up advanced IT infrastructure as servers or storage; therefore, cloud computing comprising an Infrastructure-as-a-Service (IaaS is well suited to provide such IT infrastructure in remote rural areas. Additional cloud layers of Platform-as-a-Service (PaaS and Software-as-a-Service (SaaS can be added above IaaS. Cluster-based IaaS cloud can be set up by using open-source middleware Eucalyptus in data centres of NIC. Data centres of the central and state governments can be integrated with State Wide Area Networks and NICNET together to form the e-governance grid of India. Web service repositories at centre, state, and district level can be built over the national e-governance grid of India. Using Globus Toolkit, we can achieve stateful web services with speed and security. Adding the cloud layer over the e-governance grid will make a grid-cloud environment possible through Globus Nimbus. Service delivery can be in terms of web services delivery through heterogeneous client devices. Data mining using Weka4WS and DataMiningGrid can produce meaningful knowledge discovery from data. In this paper, a plan of action is provided for the implementation of the above proposed architecture.

Application of phase change materials in thermal management of electronics

International Nuclear Information System (INIS)

Kandasamy, Ravi; Wang Xiangqi; Mujumdar, Arun S.

2007-01-01

Application of a novel PCM package for thermal management of portable electronic devices was investigated experimentally for effects of various parameters e.g. power input, orientation of package, and various melting/freezing times under cyclic steady conditions. Also, a two-dimensional numerical study was made and compared the experimental results. Results show that increased power inputs increase the melting rate, while orientation of the package to gravity has negligible effect on the thermal performance of the PCM package. The thermal resistance of the device and the power level applied to the PCM package are of critical importance for design of a passive thermal control system. Comparison with numerical results confirms that PCM-based design is an excellent candidate design for transient electronic cooling applications

The goal of the Advanced Free-Electron Laser Project at the Los Alamos National Laboratory is to demonstrate that a free-electron laser (FEL) suitable for industrial, medical, and research applications can be built. This FEL system should be efficient, compact, robust, and user-friendly. To achieve this goal, we have incorporated advanced components presently available. Electrons produced by a photoelectron source are accelerated to 20 MeV by a high-brightness accelerator. They are transported by an emittance-preserving beamline with permanent-magnet quadrupoles and dipoles. The electron beam has excellent instantaneous beam quality better than: 2.5 π mm mrad in transverse emittance and 0.3% in energy spread at a Peak current up to 310 A. It is used to excite a FEL oscillator with a pulsed-current microwiggler. Including operation at higher harmonics, the laser wavelength extends from 3.7 μm to 0.4 μm

To assess the knowledge and perceptions of Malaysian government dentists regarding the shortened dental arch (SDA) concept and its application in clinical practice. The SDA concept refers to a specific type of dentition with intact anterior teeth and a reduction in posterior occlusal pairs. Dentists' knowledge and perceptions of the SDA concept can influence its application in clinical practice. A self-administered questionnaire on the SDA concept was distributed to 326 government dentists in the states of Selangor and Kuala Lumpur, Malaysia. The data were analysed using SPSS version 22 software. The response rate was 84.0%. The majority of respondents had good knowledge on five of six knowledge items and good attitudes towards 10 of 17 perception items. However, only one-fifth (20.4%) reported having applied the SDA concept in the clinic. A larger number of participants who graduated locally than who graduated abroad perceived that patients 5 years of work experience perceived that the SDA concept enables simpler treatment planning (P concept, it is not widely applied in the clinic. Concerted efforts in SDA training of dentists are needed to help to shorten denture waiting lists and reduce costs. © 2017 FDI World Dental Federation.

Full Text Available This paper analyzes the factors underlying the development of e-government, as an overall process, as well as of each of the three stages identified in the prior literature (e-government, egovernance and e-democracy. The analysis has focused on 102 Spanish municipalities, and it consists in a content analysis of their web pages, based on an information index, in order to develop a dependency model. The results obtained indicate that Spanish municipalities show high information transparency regarding economic, environmental and social matters, allowing the undertaking of administrative proceedings online and actively promoting the participation of interest groups in strategic, sustainable and managerial issues. Our findings stress the importance of the municipality’s size and the ruling party’s political ideology of a deeper commitment with the development of e-government.

Public Policy Instruments and Their Impact: From Analogue to Electronic Government in the Bus Services of São Paulo

Directory of Open Access Journals (Sweden)

Marcos Lopes Campos

2018-04-01

Full Text Available This article deals with the relations between public policy instruments and production practices of objects related to government action. It demonstrates that the materiality of the instruments built to make a public policy object legible to its operators has independent effects on the relations among private operators, bureaucrats, and the public sector. Based on the bus service provision policies in the city of São Paulo between the 1980s and the 2000s, it shows that transportation policies are structured around the dilemmas and conflicts associated with the production of reports and databases. This article suggests that everyday practices and instruments, especially those associated with the documentation of operational performance, are key dimensions to understand the limits and potential of both state capacities and the regulation of companies’ profits. Because of its materiality, documentation practices and document pathways, operate as devices and artifacts which structure opacities, asymmetries of information, and power struggles between the state bureaucrats and private companies in the construction of service legibility. This article concludes that the transition from the governance through analogue instruments to the governance through electronic instruments is characterized by more transparency and greater regulatory potential over the private sector.

High-power free-electron lasers-technology and future applications

Science.gov (United States)

Socol, Yehoshua

2013-03-01

Free-electron laser (FEL) is an all-electric, high-power, high beam-quality source of coherent radiation, tunable - unlike other laser sources - at any wavelength within wide spectral region from hard X-rays to far-IR and beyond. After the initial push in the framework of the “Star Wars” program, the FEL technology benefited from decades of R&D and scientific applications. Currently, there are clear signs that the FEL technology reached maturity, enabling real-world applications. E.g., successful and unexpectedly smooth commissioning of the world-first X-ray FEL in 2010 increased in one blow by more than an order of magnitude (40×) wavelength region available by FEL technology and thus demonstrated that the theoretical predictions just keep true in real machines. Experience of ordering turn-key electron beamlines from commercial companies is a further demonstration of the FEL technology maturity. Moreover, successful commissioning of the world-first multi-turn energy-recovery linac demonstrated feasibility of reducing FEL size, cost and power consumption by probably an order of magnitude in respect to previous configurations, opening way to applications, previously considered as non-feasible. This review takes engineer-oriented approach to discuss the FEL technology issues, keeping in mind applications in the fields of military and aerospace, next generation semiconductor lithography, photo-chemistry and isotope separation.

Hydrogen doped thin film diamond. Properties and application for electronic devices

International Nuclear Information System (INIS)

Looi, H.J.

2000-01-01

The face centered cubic allotrope of carbon, diamond, is a semiconducting material which possesses a valuable combination of extreme properties such as super-hardness, highest thermal conductivity, chemical hardness, radiation hardness, wide bandgap and others. Advances in chemical vapour deposition (CVD) technology have lead to diamond becoming available in previously unattainable forms for example over large areas and with controllable purity. This has generated much research interest towards developing the knowledge and processing technology that would be necessary to fully exploit these extreme properties. Electronic devices fabricated on oxidised boron doped polycrystalline CVD diamond (PCD) displayed very poor and inconsistent characteristic. As a result, many electronic applications of polycrystalline diamond films were confined to ultra-violet (UV) and other forms of device which relied on the high intrinsic resistivity on undoped diamond films. If commercially accessible PCD films are to advance in areas which involve sophisticated electronic applications or to compete with existing semiconductors, the need for a more reliable and fully ionised dopant is paramount. This thesis describes a unique dopant discovered within the growth surface of PCD films. This dopant is related to hydrogen which arises during the growth of diamond films. The aim of this study is to characterise and identify possible applications for this form of dopant. The mechanism for carrier generation remains unknown and based on the experimental results in this work, a model is proposed. The Hall measurements conducted on this conductive layer revealed a p-type nature with promising properties for electronic device application. A more detail study based on electrical and surface science methods were carried out to identify the stability and operating conditions for this dopant. The properties of metal-semiconductor contacts on these surfaces were investigated. The fundamental knowledge

Peripheral dose outside applicators in electron beams

International Nuclear Information System (INIS)

Chow, James C L; Grigorov, Grigor N

2006-01-01

The peripheral dose outside the applicators in electron beams was studied using a Varian 21 EX linear accelerator. To measure the peripheral dose profiles and point doses for the applicator, a solid water phantom was used with calibrated Kodak TL films. Peak dose spot was observed in the 4 MeV beam outside the applicator. The peripheral dose peak was very small in the 6 MeV beam and was ignorable at higher energies. Using the 10 x 10 cm 2 cutout and applicator, the dose peak for the 4 MeV beam was about 12 cm away from the field central beam axis (CAX) and the peripheral dose profiles did not change with depths measured at 0.2, 0.5 and 1 cm. The peripheral doses and profiles were further measured by varying the angle of obliquity, cutout and applicator size for the 4 MeV beam. The local peak dose was increased with about 3% per degree angle of obliquity, and was about 1% of the prescribed dose (angle of obliquity equals zero) at 1 cm depth in the phantom using the 10 x 10 cm 2 cutout and applicator. The peak dose position was also shifted 7 mm towards the CAX when the angle of obliquity was increased from 0 to 15 deg. (note)

The development of organic electronic requires a non contact digital printing process. The European funded e-LIFT project investigated the possibility of using the Laser Induced Forward Transfer (LIFT) technique to address this field of applications. This process has been optimized for the deposition of functional organic and inorganic materials in liquid and solid phase, and a set of polymer dynamic release layer (DRL) has been developed to allow a safe transfer of a large range of thin films. Then, some specific applications related to the development of heterogeneous integration in organic electronics have been addressed. We demonstrated the ability of LIFT process to print thin film of organic semiconductor and to realize Organic Thin Film Transistors (OTFT) with mobilities as high as 4 10-2 cm2.V-1.s-1 and Ion/Ioff ratio of 2.8 105. Polymer Light Emitting Diodes (PLED) have been laser printed by transferring in a single step process a stack of thin films, leading to the fabrication of red, blue green PLEDs with luminance ranging from 145 cd.m-2 to 540 cd.m-2. Then, chemical sensors and biosensors have been fabricated by printing polymers and proteins on Surface Acoustic Wave (SAW) devices. The ability of LIFT to transfer several sensing elements on a same device with high resolution allows improving the selectivity of these sensors and biosensors. Gas sensors based on the deposition of semiconducting oxide (SnO2) and biosensors for the detection of herbicides relying on the printing of proteins have also been realized and their performances overcome those of commercial devices. At last, we successfully laser-printed thermoelectric materials and realized microgenerators for energy harvesting applications.

Quantum entanglement in electron optics generation, characterization, and applications

CERN Document Server

Chandra, Naresh

2013-01-01

This monograph forms an interdisciplinary study in atomic, molecular, and quantum information (QI) science. Here a reader will find that applications of the tools developed in QI provide new physical insights into electron optics as well as properties of atoms & molecules which, in turn, are useful in studying QI both at fundamental and applied levels. In particular, this book investigates entanglement properties of flying electronic qubits generated in some of the well known processes capable of taking place in an atom or a molecule following the absorption of a photon. Here, one can generate Coulombic or fine-structure entanglement of electronic qubits. The properties of these entanglements differ not only from each other, but also from those when spin of an inner-shell photoelectron is entangled with the polarization of the subsequent fluorescence. Spins of an outer-shell electron and of a residual photoion can have free or bound entanglement in a laboratory.

An Evaluation of Dynamic Partial Reconfiguration for Signal and Image Processing in Professional Electronics Applications

Directory of Open Access Journals (Sweden)

Aulagnier Denis

2008-01-01

Full Text Available Abstract Signal and image processing applications require a lot of computing resources. For low-volume applications like in professional electronics applications, FPGA are used in combination with DSP and GPP in order to reach the performances required by the product roadmaps. Nevertheless, FPGA designs are static, which raises a flexibility issue with new complex or software defined applications like software-defined radio (SDR. In this scope, dynamic partial reconfiguration (DPR is used to bring a virtualization layer upon the static hardware of FPGA. During the last decade, DPR has been widely studied in academia. Nevertheless, there are very few real applications using it, and therefore, there is a lack of feedback providing relevant issues to address in order to improve its applicability. This paper evaluates the interest and limitations when using DPR in professional electronics applications and provides guidelines to improve its applicability. It makes a fair evaluation based on experiments made on a set of signal and image processing applications. It identifies the missing elements of the design flow to use DPR in professional electronics applications. Finally, it introduces a fast reconfiguration manager providing an 84-time improvement compared to the vendor solution.

Full Text Available In this study, it is examined for the period 2000- 2015 in Turkey that increasing the electronic applications regarding tax audits had the effects on the required amount of tax levied as a result of tax audits. Tax Inspectors reach strategic information without uneasiness by means of electronic applications developed by some institutions such as Electronic Risk Analysis that Tax Inspection Board founded in 2011 and Revenue Administration as institutions designated by law for auditing tax in Turkey. Thus, this leads to an increase the tax revenues obtained in the course of tax audits compared to the times when there is not electronic applications.

Governance in Health – The Need for Exchange and Evidence; Comment on “Governance, Government, and the Search for New Provider Models”

Directory of Open Access Journals (Sweden)

Tata Chanturidze

2016-08-01

Full Text Available Governance in health is cited as one of the key factors in balancing the concerns of the government and public sector with the interests of civil society/private players, but often remains poorly described and operationalized. Richard Saltman and Antonio Duran look at two aspects in the search for new provider models in a context of health markets signalling liberalisation: (i the role of the government to balance public and private interests and responsibilities in delivering care through modernised governance arrangements, and (ii the finding that operational complexities may hinder well–designed provider governance models, unless governance reflects country-specific realities. This commentary builds on the discussion by Saltman and Duran, and argues that the concept of governance needs to be clearly defined and operationalized in order to be helpful for policy debate as well as for the development of an applicable framework for performance improvement. It provides a working definition of governance and includes a reflection on the prevailing cultural norms in an organization or society upon which any governance needs to be build. It proposes to explore whether the “evidence-based governance” concept can be introduced to generate knowledge about innovative and effective governance models, and concludes that studies similar to the one by Saltman and Duran can inform this debate.

This paper reviews the subject of Si quantum dots embedded in dielectric and its application to the realization of non volatile semiconductor memories. In the first part of the paper various approaches for the analysis of the materials through transmission electron microscopy (TEM) are critically discussed. The advantages coming from an innovative application of energy filtered TEM are put in clear evidence. The paper then focuses on the synthesis of the materials: two different methodologies for the realization of the dots, both based on chemical vapor deposition are described in detail, and physical models providing some understanding of the observed phenomenology are reported. We then discuss the application of this nano technology to the realization of the storage nodes in non volatile semiconductor memories. The following sections describe the electrical characteristics found in the test devices and some key aspects are described in terms of quantitative models. The test devices show several performance advantages, indicating that the approach is an excellent candidate for the realization of Flash memories of the nano electronic era

Cotton-based Cellulose Nanomaterials for Applications in Composites and Electronics

Science.gov (United States)

Farahbakhsh, Nasim

A modern society demands development of highly valued and sustainable products via innovative process technologies and utilizing bio-based alternatives for petroleum based materials. Systematic comparative study of nanocellulose particles as a biodegradable and renewable reinforcing agent can help to develop criteria for selecting an appropriate candidate to be incorporated in polymer nanocomposites. Of particular interest has been nanocellulosic materials including cellulose nanocrystal (CNC) and micro/nanofibrilated cellulose (MFC/NFC) which possess a hierarchical structure that permits an ordered structure with unique properties that has served as building blocks for the design of green and novel materials composites for applications in flexible electronics, medicine and composites. Key differences exist in nanocellulosic materials as a result the process by which the material is produced. This research demonstrates the applicability for the use of recycled cotton as promising sustainable material to be utilized as a substrate for electronic application and a reinforcing agent choice that can be produced without any intensive purification process and be applied to synthetic-based polymer nanocomposites in melt-processing.

The progress in high energy welding is remarkable in recent years, and electron beam welding is now widely used in heavy industries. However, there are number of problems to be solved in the application of high power electron beam welding to ultra thick steel plates (over 100 mm). The following matters are described: the economy of high power electron beam welding; the development of the welding machines; the problems in the actual application; the instances of the welding in a high-pressure spherical gas tank, non-magnetic steel structures and high-precision welded structures; weldor training; etc. For the future rise in the capacities of heavy electric machinery, the high efficiency by high power electron beam welding will be useful. The current status is its applications to the high-precision welding of large structures with 6 m diameter and the high-quality welding of heavy structures with 160 mm thickness. (J.P.N.)

Social Media Used by Government Institutions in Iceland: Application, Role and Aims

Directory of Open Access Journals (Sweden)

Már Einarsson

2014-12-01

Full Text Available The purpose of this research was to study the use and role of social media hosted by government institutions in Iceland. The research was conducted using quantitative and qualitative research methods. A survey was sent electronically to all government institutions in Iceland and semi-structured interviews were conducted with specialists working for institutions. No research has been conducted on this subject in Iceland before. It was therefore considered timely that a research was conducted on the use of social media in public institutions, with the intention of adding new knowledge to the field. No similar research from outside of Iceland was found, but this research was based on related studies and sources from abroad. A little less than half of government institutions used social media as part of their activities and Facebook and YouTube were most widely used. Popularity, circulation, usefulness and convenience were the most important factors when choosing social media. The majority of institutions had neither defined social media goals nor the role and responsibility of employees when using social media. The institutions placed strong emphasis on publishing adverts and news items on the institutions’ activities via social media pages and there were a considerable number of references to material on other web pages. Among other things the interviewees said that the purpose of using social media was information dissemination, reception of information, more visibility, the opening of institutions to the public and increased transparency. They talked about the importance of being informal on social media, but they also pointed out that there had been some fear among institutions of using them, in particular fear of employees showing a human side via social media. There was minimal use of original material on institutions’ social media pages, while institutions were quite systematic in posting material from their website through social media

Flexible organic electronic devices: Materials, process and applications

International Nuclear Information System (INIS)

Logothetidis, Stergios

2008-01-01

The research for the development of flexible organic electronic devices (FEDs) is rapidly increasing worldwide, since FEDs will change radically several aspects of everyday life. Although there has been considerable progress in the area of flexible inorganic devices (a-Si or solution processed Si), there are numerous advances in the organic (semiconducting, conducting and insulating), inorganic and hybrid (organic-inorganic) materials that exhibit customized properties and stability, and in the synthesis and preparation methods, which are characterized by a significant amount of multidisciplinary efforts. Furthermore, the development and encapsulation of organic electronic devices onto flexible polymeric substrates by large-scale and low-cost roll-to-roll production processes will allow their market implementation in numerous application areas, including displays, lighting, photovoltaics, radio-frequency identification circuitry and chemical sensors, as well as to a new generation of modern exotic applications. In this work, we report on some of the latest advances in the fields of polymeric substrates, hybrid barrier layers, inorganic and organic materials to be used as novel active and functional thin films and nanomaterials as well as for the encapsulation of the materials components for the production of FEDs (flexible organic light-emitting diodes, and organic photovoltaics). Moreover, we will emphasize on the real-time optical monitoring and characterization of the growing films onto the flexible polymeric substrates by spectroscopic ellipsometry methods. Finally, the potentiality for the in-line characterization processes for the development of organic electronics materials will be emphasized, since it will also establish the framework for the achievement of the future scientific and technological breakthroughs

2018-02-01

The ability of academic medical centers (AMCs) to fulfill their triple mission of patient care, medical education, and research is increasingly being threatened by rising financial pressures and resource constraints. Many AMCs are, therefore, looking to expand into academic medical systems, increasing their scale through consolidation or affiliation with other health care systems. As clinical operations grow, though, the need for effective governance becomes even more critical to ensure that the business of patient care does not compromise the rest of the triple mission. Multi-AMC systems, a model in which multiple AMCs are governed by a single body, pose a particular challenge in balancing unity with the needs of component AMCs, and therefore offer lessons for designing AMC governance approaches. This article describes the development and application of a set of criteria to evaluate governance options for one multi-AMC system-the University of California (UC) and its five AMCs. Based on a literature review and key informant interviews, the authors identified criteria for evaluating governance approaches (structures and processes), assessed current governance approaches using the criteria, identified alternative governance options, and assessed each option using the identified criteria. The assessment aided UC in streamlining governance operations to enhance their ability to respond efficiently to change and to act collectively. Although designed for UC and a multi-AMC model, the criteria may provide a systematic way for any AMC to assess the strengths and weaknesses of its governance approaches.

On the Origin of Intermediary E-Government Services

Science.gov (United States)

Arendsen, Rex; Ter Hedde, Marc J.

The majority of SME’s tends to outsource administrative tasks, including their direct relationships with the (electronic) government. Commercial intermediary service providers therefore have to be part of governmental multi channel e-service delivery strategies. This research paper explores the origin, added value and future position of these intermediary organisations with respect to the delivery of e-government services to businesses. Results indicate that (re-)intermediation is more likely to occur within this context than disintermediation is. SME’s do not want to be captured within a non-profitable electronic hierarchical relationship with a governmental organisation. The empirical study on the impact of the legal obligation of the use of e-tax services illustrates that SME’s instead prefer the ‘save haven’ of a commercial relationship with an intermediary service provider. Thus creating and fuelling a new market of intermediary e-government services.

Electron Beam Irradiated Intercalated CNT Yarns For Aerospace Applications

Science.gov (United States)

Waters, Deborah L.; Gaier, James R.; Williams, Tiffany S.; Lopez Calero, Johnny E.; Ramirez, Christopher; Meador, Michael A.

2015-01-01

Multi-walled CNT yarns have been experimentally and commercially created to yield lightweight, high conductivity fibers with good tensile properties for application as electrical wiring and multifunctional tendons. Multifunctional tendons are needed as the cable structures in tensegrity robots for use in planetary exploration. These lightweight robust tendons can provide mechanical strength for movement of the robot in addition to power distribution and data transmission. In aerospace vehicles, such as Orion, electrical wiring and harnessing mass can approach half of the avionics mass. Use of CNT yarns as electrical power and data cables could reduce mass of the wiring by thirty to seventy percent. These fibers have been intercalated with mixed halogens to increase their specific electrical conductivity to that near copper. This conductivity, combined with the superior strength and fatigue resistance makes it an attractive alternative to copper for wiring and multifunctional tendon applications. Electron beam irradiation has been shown to increase mechanical strength in pristine CNT fibers through increased cross-linking. Both pristine and intercalated CNT yarns have been irradiated using a 5-megavolt electron beam for various durations and the conductivities and tensile properties will be discussed. Structural information obtained using a field emission scanning electron microscope, energy dispersive X-ray spectroscopy (EDS), and Raman spectroscopy will correlate microstructural details with bulk properties.

Toward an E-Government Semantic Platform

Science.gov (United States)

Sbodio, Marco Luca; Moulin, Claude; Benamou, Norbert; Barthès, Jean-Paul

This chapter describes the major aspects of an e-government platform in which semantics underpins more traditional technologies in order to enable new capabilities and to overcome technical and cultural challenges. The design and development of such an e-government Semantic Platform has been conducted with the financial support of the European Commission through the Terregov research project: "Impact of e-government on Territorial Government Services" (Terregov 2008). The goal of this platform is to let local government and government agencies offer online access to their services in an interoperable way, and to allow them to participate in orchestrated processes involving services provided by multiple agencies. Implementing a business process through an electronic procedure is indeed a core goal in any networked organization. However, the field of e-government brings specific constraints to the operations allowed in procedures, especially concerning the flow of private citizens' data: because of legal reasons in most countries, such data are allowed to circulate only from agency to agency directly. In order to promote transparency and responsibility in e-government while respecting the specific constraints on data flows, Terregov supports the creation of centrally controlled orchestrated processes; while the cross agencies data flows are centrally managed, data flow directly across agencies.

Field Emitter Arrays for a Free Electron Laser Application

Shing-Bruce-Li, Kevin; Ganter, Romain; Gobrecht, Jens; Raguin, Jean Yves; Rivkin, Leonid; Wrulich, Albin F

2004-01-01

The development of a new electron gun with the lowest possible emittance would help reducing the total length and cost of a free electron laser. Field emitter arrays (FEAs) are an attractive technology for electron sources of ultra high brightness. Indeed, several thousands of microscopic tips can be deposited on a 1 mm diameter area. Electrons are then extracted by applying voltage to a first grid layer close to the tip apexes, the so called gate layer, and focused by a second grid layer one micrometer above the tips. The typical aperture diameter of the gate and the focusing layer is in the range of one micrometer. One challenge for such cathodes is to produce peak currents in the ampere range since the usual applications of FEAs require less than milliampere. Encouraging peak current performances have been obtained by applying voltage pulses at low frequency between gate and tips. In this paper we report on different tip materials available on the market: diamond FEAs from Extreme Devices Inc., ZrC single ...

Many new applications of the selfshielded electron processor have emerged over the past 5 years which continue to demonstrate the advantages and practical problems associated with these efficient, compact energy sources. Many of these, such as for the curing of: binders for abrasive products, binders for magnetic media, binders for textile flocking, silicone coatings for release papers, etc., offer good prospects for growth but are thusfar in limited use. With this ever broadening base of process technology, the prospects remain 'bullish' for the expanded industrial use of these new energy sources. With their unrivalled process off-licences and high throughputs, improved appreciation of their advantageous economics assures expanded application in an increasingly energy/environmentally concerned world economy(author)

The central role of government in the governing processes has predominantly been adopted. The concept of governance was emerged precisely in the context of the failure of government as key player in regulation, economic redistribution and political participation. Governance is therefore aimed to emphasize pattern of governing which are based both on democratic mechanism and sound development management. However, practices of such good governance concept –which are mainly adopted and promoted by donor states and agencies– tend to degrade state and/or government authority and legitimacy. Traditional function of the state as sole facilitator of equal societal, political and legal membership among citizens has been diminished. The logic of fair competition has been substituted almost completely by the logic of free competition in nearly all sectors of public life. The concept and practices of good governance have resulted in decayed state authority and failed state which in turn created a condition for "ungovernability". By promoting democratic and humane governance, the article accordingly encourages discourse to reinstall and bring the idea of accountable state back in.

Porphyrins are conjugated, stable chromophores with a central core that binds a variety of metal ions and an easily functionalized peripheral framework. By combining the catalytic, electronic or cytotoxic properties of selected transition metal complexes with the binding and electronic properties of porphyrins, enhanced characteristics of the ensemble are generated. This review article focuses on porphyrins bearing one or more peripheral transition metal complexes and discusses their potential applications in catalysis or biomedicine. Modulation of the electronic properties and intramolecular communication through coordination bond linkages in bis-porphyrin scaffolds is also presented. © 2018 WILEY-VCH Verlag GmbH & Co.

III - V semiconductor structures for biosensor and molecular electronics applications

Energy Technology Data Exchange (ETDEWEB)

Luber, S M

2007-01-15

The present work reports on the employment of III-V semiconductor structures to biosensor and molecular electronics applications. In the first part a sensor based on a surface-near two dimensional electron gas for a use in biological environment is studied. Such a two dimensional electron gas inherently forms in a molecular beam epitaxy (MBE) grown, doped aluminum gallium arsenide - gallium arsenide (AlGaAs-GaAs) heterostructure. Due to the intrinsic instability of GaAs in aqueous solutions the device is passivated by deposition of a monolayer of 4'-substituted mercaptobiphenyl molecules. The influence of these molecules which bind to the GaAs via a sulfur group is investigated by Kelvin probe measurements in air. They reveal a dependence of GaAs electron affinity on the intrinsic molecular dipole moment of the mercaptobiphenyls. Furthermore, transient surface photovoltage measurements are presented which demonstrate an additional influence of mercaptobiphenyl chemisorption on surface carrier recombination rates. As a next step, the influence of pH-value and salt concentration upon the sensor device is discussed based on the results obtained from sensor conductance measurements in physiological solutions. A dependence of the device surface potential on both parameters due to surface charging is deduced. Model calculations applying Poisson-Boltzmann theory reveal as possible surface charging mechanisms either the adsorption of OH- ions on the surface, or the dissociation of OH groups in surface oxides. A comparison between simulation settings and physical device properties indicate the OH- adsorption as the most probable mechanism. In the second part of the present study the suitability of MBE grown III-V semiconductor structures for molecular electronics applications is examined. In doing so, a method to fabricate nanometer separated, coplanar, metallic electrodes based on the cleavage of a supporting AlGaAs-GaAs heterostructure is presented. This is followed by a

Electoral Governance in Brazil

Directory of Open Access Journals (Sweden)

Vitor Marchetti

2012-06-01

Full Text Available Electoral governance has increasingly more frequently been the object of study of the comparative politics literature. This article examines the electoral governance institutional model adopted in Brazil and its consequences for political/electoral competition. It is argued herein that Brazil’s Electoral Justice System, motivated by the institutional design, has ended up becoming one of the main actors of the country’s recent democratic consolidation, being decisive not only with regard to rule adjudication and application, but also to rulemaking. With the purpose of assessing this governance model in action, three important recent rulings by Brazil’s Electoral Justice System are analysed here: verticalization of the coalitions, reduction in the number of councillors, and party loyalty.

Nanotechnology and the need for risk governance

International Nuclear Information System (INIS)

Renn, O.; Roco, M. C.

2006-01-01

After identifying the main characteristics and prospects of nanotechnology as an emerging technology, the paper presents the general risks associated with nanotechnology applications and the deficits of the risk governance process today, concluding with recommendations to governments, industry, international organizations and other stakeholders. The International Risk Governance Council (IRGC) has identified a governance gap between the requirements pertaining to the nano- rather than the micro-/macro- technologies. The novel attributes of nanotechnology demand different routes for risk-benefit assessment and risk management, and at present, nanotechnology innovation proceeds ahead of the policy and regulatory environment. In the shorter term, the governance gap is significant for those passive nanostructures that are currently in production and have high exposure rates; and is especially significant for the several 'active' nanoscale structures and nanosystems that we can expect to be on the market in the near future. Active nanoscale structures and nanosystems have the potential to affect not only human health and the environment but also aspects of social lifestyle, human identity and cultural values. The main recommendations of the report deal with selected higher risk nanotechnology applications, short- and long-term issues, and global models for nanotechnology governance

The peripheral dose outside the applicator in electron beams of Oncor linear accelerator

International Nuclear Information System (INIS)

Iktueren, B.; Bilge, H.; Karacam, S.; Atkovar, G.

2012-01-01

In this study, the peripheral dose outside the applicator was measured using electron beams produced by an Oncor linear accelerator and compared with the data of the treatment planning system (TPS). The dose profiles have been measured, by using a water-equivalent slab phantom and a parallel plate ionisation chamber, at 6, 9 and 15 MeV energy levels in 5 x 5, 10 x 10, 15 x 15, 20 x 20 and 25 x 25 cm 2 applicators and at 0, 10 and 20 deg. gantry angles; and at the surface, 0.2, 0.5, 1 cm and d max depth for each electron energy level. The peripheral dose has been determined with these profiles by normalisation at the field central beam axis (CAX). It has been noticed that, using a 10 x 10 cm 2 applicator, there is a 1.4 % dose peak on the surface 6 cm away from the field edge where the field CAX is at 100 %, at a gantry angle of 0 deg. with 6 and 9 MeV electron beams; also for the 15 MeV electron beam there is a 2.3 % dose peak. It has been discovered that the peak dose approaches a minimum depending on the increase in depth and reaches 2.5-4 % depending on the growth of the field dimension. At gantry angles of 10 and 20 deg., 6 and 9 MeV electron beams created small peaks and a maximum dose could be reached at 0.2 and 1 cm depth. Electron beam of 15 MeV did not peak at depths of 0.2 and 1 cm at gantry angles of 10 and 20 deg.. The measured peripheral dose outside the applicators has been compared with the data from a TPS's computer using the Pencil Beam algorithm; it has been stated that dose calculations can be made as far as 3 cm outside the field. In conclusion, the TPS is not sufficient to measure the peripheral dose outside the applicators, and this dose can only be determined by direct measurement. (authors)

This paper reports results of transverse emittance studies and beam propagation in electrostatic accelerators for free electron laser applications. In particular, we discuss emittance growth analysis of a low current electron beam system consisting of a miniature thermoionic electron gun and a National Electrostatics Accelerator (NEC) tube. The emittance growth phenomenon is discussed in terms of thermal effects in the electron gun cathode and aberrations produced by field gradient changes occurring inside the electron gun and throughout the accelerator tube. A method of reducing aberrations using a magnetic solenoidal field is described. Analysis of electron beam emittance was done with the EGUN code. Beam propagation along the accelerator tube was studied using a cylindrically symmetric beam envelope equation that included beam self-fields and the external accelerator fields which were derived from POISSON simulations.

Penelope - a code system for Monte Carlo simulation of electron and photon transport

International Nuclear Information System (INIS)

2003-01-01

Radiation is used in many applications of modern technology. Its proper handling requires competent knowledge of the basic physical laws governing its interaction with matter. To ensure its safe use, appropriate tools for predicting radiation fields and doses, as well as pertinent regulations, are required. One area of radiation physics that has received much attention concerns electron-photon transport in matter. PENELOPE is a modern, general-purpose Monte Carlo tool for simulating the transport of electrons and photons, which is applicable for arbitrary materials and in a wide energy range. PENELOPE provides quantitative guidance for many practical situations and techniques, including electron and X-ray spectroscopies, electron microscopy and microanalysis, biophysics, dosimetry, medical diagnostics and radiotherapy, as well as radiation damage and shielding. These proceedings contain the extensively revised teaching notes of the second workshop/training course on PENELOPE held in 2003, along with a detailed description of the improved physic models, numerical algorithms and structure of the code system.

Indium antimonide quantum well structures for electronic device applications

Science.gov (United States)

Edirisooriya, Madhavie

The electron effective mass is smaller in InSb than in any other III-V semiconductor. Since the electron mobility depends inversely on the effective mass, InSb-based devices are attractive for field effect transistors, magnetic field sensors, ballistic transport devices, and other applications where the performance depends on a high mobility or a long mean free path. In addition, electrons in InSb have a large g-factor and strong spin orbit coupling, which makes them well suited for certain spin transport devices. The first n-channel InSb high electron mobility transistor (HEMT) was produced in 2005 with a power-delay product superior to HEMTs with a channel made from any other III-V semiconductor. The high electron mobility in the InSb quantum-well channel increases the switching speed and lowers the required supply voltage. This dissertation focuses on several materials challenges that can further increase the appeal of InSb quantum wells for transistors and other electronic device applications. First, the electron mobility in InSb quantum wells, which is the highest for any semiconductor quantum well, can be further increased by reducing scattering by crystal defects. InSb-based heteroepitaxy is usually performed on semi-insulating GaAs (001) substrates due to the lack of a lattice matched semi-insulating substrate. The 14.6% mismatch between the lattice parameters of GaAs and InSb results in the formation of structural defects such as threading dislocations and microtwins which degrade the electrical and optical properties of InSb-based devices. Chapter 1 reviews the methods and procedures for growing InSb-based heterostructures by molecular beam epitaxy. Chapters 2 and 3 introduce techniques for minimizing the crystalline defects in InSb-based structures grown on GaAs substrates. Chapter 2 discusses a method of reducing threading dislocations by incorporating AlyIn1-ySb interlayers in an AlxIn1-xSb buffer layer and the reduction of microtwin defects by growth

Huai, Jinmei

This paper developed an approach to e-government outsourcing quality management. E-government initiatives have rapidly increased in the last decades and the success of these activities will largely depend on their operation quality. As an instrument to improve operation quality, outsourcing can be applied to e-government. This paper inspected process of e-government outsourcing and discussed how to improve the outsourcing performance through total quality management (TQM). The characteristics and special requirements of e-government outsourcing were analyzed as the basis for discussion. Then the principles and application of total quality management were interpreted. Finally the process of improving performance of e-government was analyzed in the context of outsourcing.

Exciton confinement in organic dendrimer quantum wells for opto-electronic applications

Science.gov (United States)

Lupton, J. M.; Samuel, I. D. W.; Burn, P. L.; Mukamel, S.

2002-01-01

Organic dendrimers are a fascinating new class of materials for opto-electronic applications. We present coupled electronic oscillator calculations on novel nanoscale conjugated dendrimers for use in organic light-emitting diodes. Strong confinement of excitations at the center of the dendrimers is observed, which accounts for the dependence of intermolecular interactions and charge transport on the degree of branching of the dendrimer. The calculated absorption spectra are in excellent agreement with the measured data and show that benzene rings are shared between excitations on the linear segments of the hyperbranched molecules. The coupled electronic oscillator approach is ideally suited to treat large dendritic molecules.

It has been shown that the desorption mechanism is associated with the electron part of the stopping power of the primary ion and the name 'electron sputtering' has been adopted for the phenomenon to distinguish it from the well-known sputtering process with ions of KeV energy. A review of electronic sputtering of biomolecules will be given as well as recent measurements on Langmuir-Blodgett films. One important application of electronic sputtering is in the field of mass spectrometry. With this technique large and nonvolatile molecules can be studied. Particularly adsorption of biomolecules to a nitrocellulose backing has proven to be very useful. Examples will be given of mass spectra from peptides with a molecular weight above 20,000 u.

Lack of government performance, among others due to the lack of coordination and communication among government agencies. Whilst, Enterprise Architecture (EA) in the government can be use as a strategic planning tool to improve productivity, efficiency, and effectivity. However, the existence components of Government Enterprise Architecture (GEA) do not show level of importance, that cause difficulty in implementing good e-government for good governance. This study is to explore the weight of GEA components using Principal Component Analysis (PCA) in order to discovered an inherent structure of e-government. The results show that IT governance component of GEA play a major role in the GEA. The rest of components that consist of e-government system, e-government regulation, e-government management, and application key operational, contributed more or less the same. Beside that GEA from other countries analyzes using comparative base on comon enterprise architecture component. These weighted components use to construct i-Government enterprise architecture. and show the relative importance of component in order to established priorities in developing e-government.

Electronic and optoelectronic device applications based on ReS2

Science.gov (United States)

Liu, Erfu; Long, Mingsheng; Wang, Yaojia; Pan, Yiming; Ho, Chinghwa; Wang, Baigeng; Miao, Feng

Rhenium disulfide (ReS2) is a unique semiconducting TMD with distorted 1T structure and weak interlayer coupling. We have previously investigated its in-plane anisotropic property and electronic applications on FET and digital inverters. In this talk, we will present high responsivity phototransistors based on few-layer ReS2. Depending on the back gate voltage, source drain bias and incident optical light intensity, the maximum attainable photoresponsivity can reach as high as 88,600 A W-1, which is one of the highest value among individual two-dimensional materials with similar device structures. Such high photoresponsivity is attributed to the increased light absorption as well as the gain enhancement due to the existence of trap states in the few-layer ReS2 flakes. The existence of trap states is proved by temperature dependent transport measurements. It further enables the detection of weak signals. Our studies underscore ReS2 as a promising material for future electronic and sensitive optoelectronic applications.

2013-12-01

Full Text Available The Gradual collapse of financial markets in the European Union since the fall of 2008 and economic crises at the credits portfolio level that followed, were generated by the several factors, often interdependent, both macroeconomic and microeconomic level, finally leading to the accumulation of excessive risk in the financial system. This excessive risk was partially caused by the deficiencies in Corporate Governance of the Financial Institutions and the especially banks deficiencies. Even if we can’t put down to the Corporate Governance crisis started, yet nonexistent or inadequacy of effective control mechanisms have determined to the excessive risk-taking by most credit institutions. This article aims to evaluate the application of Corporate Governance principles of the significant players within the Romanian banking system. The research methodology was based essentially on the technique of using the questionnaire, on Corporate Governance documents remarks published on the banks analyzed websites and on the using scoring methods in evaluating the application of Corporate Governance principles.

Science.gov (United States)

Srivastava, Anoop Kumar

In this paper, we present an application of Artificial Intelligence (AI) to the implementation of Electronic Commerce. We provide a multi autonomous agent based framework. Our agent based architecture leads to flexible design of a spectrum of multiagent system (MAS) by distributing computation and by providing a unified interface to data and programs. Autonomous agents are intelligent enough and provide autonomy, simplicity of communication, computation, and a well developed semantics. The steps of design and implementation are discussed in depth, structure of Electronic Marketplace, an ontology, the agent model, and interaction pattern between agents is given. We have developed mechanisms for coordination between agents using a language, which is called Virtual Enterprise Modeling Language (VEML). VEML is a integration of Java and Knowledge Query and Manipulation Language (KQML). VEML provides application programmers with potential to globally develop different kinds of MAS based on their requirements and applications. We have implemented a multi autonomous agent based system called VE System. We demonstrate efficacy of our system by discussing experimental results and its salient features.

Is small beautiful? A multicriteria assessment of small-scale energy technology applications in local governments

International Nuclear Information System (INIS)

Burton, Jonathan; Hubacek, Klaus

2007-01-01

In its 2003 White Paper the UK government set ambitious renewable energy targets. Local governments and households have an increasing role in the overall energy system as consumers, suppliers of smaller-scale applications and citizens discussing energy projects. In this paper, we consider if small-scale or large-scale approaches to renewable energy provision can achieve energy targets in the most socially, economically and environmentally (SEE) effective way. We take a local case study of renewable energy provision in the Metropolitan Borough of Kirklees in Yorkshire, UK, and apply a multi-criteria decision analysis methodology to compare the small-scale schemes implemented in Kirklees with large-scale alternatives. The results indicate that small-scale schemes are the most SEE effective, despite large-scale schemes being more financially viable. The selection of the criteria on which the alternatives are assessed and the assigned weights for each criterion are of crucial importance. It is thus very important to include the relevant stakeholders to elicit this information

Optimization and application of electron acceleration in relativistic laser plasmas

International Nuclear Information System (INIS)

Koenigstein, Thomas

2013-01-01

This thesis describes experiments and simulations of the acceleration of electrons to relativistic energies (toward γ e ∼ 10 3 ) by structures in plasmas which are generated by ultrashort (pulse length < 10 -14 s) laser pulses. The first part of this work discusses experiments in a parameter space where quasimonoenergetic electron bunches are generated in subcritical (gaseous) plasmas and compares them to analytical scalings. A primary concern in this work is to optimize the stability of the energy and the pointing of the electrons. The second part deals with acceleration of electrons along the surface of solid substrates by laser-plasma interaction. The measurements show good agreement with existing analytical scalings and dedicated numerical simulations. In the third part, two new concepts for multi-stage acceleration will be presented and parameterised by analytical considerations and numerical simulations. The first method uses electron pairs, as produced in the first part, to transfer energy from the first bunch to the second by means of a plasma wave. The second method utilizes a low intensity laser pulse in order to inject electrons from a neutral gas into the accelerating phase of a plasma wave. The final chapter proposes and demonstrates a first application that has been developed in collaboration with ESA. The use of electron beams with exponential energy distribution, as in the second part of this work, offers the potential to investigate the resistance of electronic components against space radiation exposure.

Application of the Electron paramagnetic resonance to the ionizing radiation dosimetry

International Nuclear Information System (INIS)

Urena N, F.

2000-01-01

The Electron Paramagnetic Resonance (EPR) is defined as the resonant absorption of electromagnetic energy in paramagnetic substances by the spin transition of a non-pairing electron between different energy levels in presence of a magnetic field. (Slighter, 1989). One of the more important characteristic of EPR is that the electron spin levels are subdivided by the electron interaction with the magnetic dipoles of the nearby nucleus giving occasion for a spectral structure called hyperfine structure. In this kind of interactions two limit cases are distinguished: 1. when the non-pairing electron is located in a central ion surrounded of atoms belonging to coordinate molecules. 2. When a non-pairing electron interactioning in the same form with a number of equivalent nucleus, which is common in organic radicals, these will give as result spectra. Some EPR spectrometer can be used to dosimetric purposes by free radicals via. In this work, it is presented the application of EPR to dosimetry of ionizing radiations by free radicals via which allows to determinations of high doses. (Author)

Electron beams and applications

Haouat, G.; Couillaud, C.

1998-01-01

Studies of the physical properties of the ELSA-linac electron beam are presented. They include measurements of the characteristic beam parameter and analyzes of the beam transport using simulation codes. The aim of these studies is to determine the best conditions for production of intense and very short electron bunches and to optimize the transport of space-charge dominated beams. Precise knowledge of the transport dynamics allows to produce beams with the required characteristics for light production in Free-Electron Laser (FEL), and to give a good description of energy-transfer phenomena between electrons and photons in the wriggler. The particular features of ELSA authorize studies of high-intensity, high-brightness beam properties, especially the halo surrounding the dense core of the electron bunches, which is formed by the space charge effects. It is also shown that the ELSA facility is well suited for the fabrication of very short γ and X-rays sources for applied research in nuclear and plasma physics, or for time response studies of fast detectors.

The role of risk management in corporate governance: Guidelines and applications

Directory of Open Access Journals (Sweden)

Hugh Grove

2017-11-01

Full Text Available Risk management should be a key concern of board members to enhance corporate governance in any organization. Eleven key numbers, ratios, and models were advocated in this paper for risk management analyses, including an analysis of their variability with graphs. They are applied to Kaisa, a Chinese property developer, located in Shenzhen but incorporated with limited liability in the Cayman Islands. The importance of such risk management analyses was demonstrated in this paper as Kaisa destroyed $12.9 billion in four different types of investments: $2.2 billion in stock market value, $0.3 billion in private equity investments, $2.5 billion in global bonds, and $7.9 billion in Chinese short-term and long-term debt. Thus, the use of key financial statement metrics, including fraud models and ratios, has been shown here to provide enhanced corporate governance with risk management guidelines and applications. Boards of Directors need to pay attention to key financial statement metrics, which have been shown to work over and over again, as with Kaisa in this paper. These key metrics usually start with operating cash flows which then may indicate problems with debt service (the fixed charge coverage ratio which then may lead to bankruptcy predictions by the Altman bankruptcy model. To cover up such survival problems, companies often resort to earnings management and even fraudulent financial reporting which are typically red flagged by the quality of earnings, the quality of revenues, the new fraud model and the old fraud model

Weak measurement from the electron displacement current: new path for applications

International Nuclear Information System (INIS)

Marian, D; Colomés, E; Oriols, X; Zanghì, N

2015-01-01

The interest on weak measurements is rapidly growing during the last years as a unique tool to better understand and predict new quantum phenomena. Up to now many theoretical and experimental weak-measurement techniques deal with (relativistic) photons or cold atoms, but there is much less investigation on (non-relativistic) electrons in up-to-date electronics technologies. We propose a way to perform weak measurements in nanoelectronic devices through the measurement of the total current (particle plus displacement component) in such devices. We study the interaction between an electron in the active region of a electron device with a metal surface working as a sensing electrode by means of the (Bohmian) conditional wave function. We perform numerical (Monte Carlo) simulations to reconstruct the Bohmian trajectories in the iconic double slit experiment. This work opens new paths for understanding the quantum properties of an electronic system as well as for exploring new quantum engineering applications in solid state physics. (paper)

Coelho, Talita S.; Tada, Ariane; Antonio, Patricia L.; Yoriyaz, Helio; Fernandes, Marco A.R.

2009-01-01

Studies have been shown that among several methods that have been used for the treatment of keloids the surgical excision followed by the adjuvant radiotherapy presents the lowest relapsed rate of the injury. In this work a comparative dosimetric study has been performed using a 4 MeV electron beam from a Varian Clinac 2100C linear accelerator at the radiotherapy service of the Hospital das Clinicas of UNESP-HC, Botucatu-SP and an Amershan 90 Sr+ 90 Y brachytherapy applicator with 1491 MBq of activity. Percentage depth dose curves from ionization chamber measurements and through Monte Carlo simulation have been obtained and compared. Dose measurements have been obtained using parallel plates ionization chamber (Esradin A12) and extrapolation mini-chamber developed at IPEN. The dose calculations have been obtained using the well-known Monte Carlo radiation transport code MCNP-4C. Maximum dose differences obtained between measured/calculated values for 90 Sr+ 90 Y applicator and for the electron beam were, respectively: 7.8 % and 8.0%. The profiles of the depth and superficial tissue dose distribution produced by the electron beam revealed themselves flatter and more homogeneous than those produced by the 90 Sr+ 90 Y applicator, especially to wider fields, which cannot be obtained with beta therapy applicators because of their geometric limitations. In conclusion this present work has shown that 90 Sr+ 90 Y applicators could be efficient for small and very superficial lesions but in most cases electron beam sources are more adequate especially for large and deeper lesions.

Multidirectional Networks of Government Transparency: A Preliminary Model

Directory of Open Access Journals (Sweden)

Ahmad Subhan

2016-11-01

Full Text Available This article reviews some literature in theoretical level regarding two concepts: governance network and government transparency, in order to search for theoretical linkages and to build an alternative framework that can support the implementation of public disclosure. Transparency agenda has been implemented in various forms at international, national, and local level. Transparency application was also followed by Indonesia with the implementation of Public Information Disclosure Law since 2008. This enthusiasm is quite reasonable because transparency is believed to be one of the human rights principles; as well as a key to better governance, that can help democracy consolidation, prevent corruption, strengthen the legitimacy and improve efficiency. In order to maximize transparency, the government can use a network approach because of some changes at this time, such as democratization, decentralization, and liberalization has placed the government in a position where there is not one actor who manages the state power without stakeholder’s participation. In this context, the government needs to build synergies with other institutions in a reciprocal relationship with all stakeholders. Therefore, adopting the theory of government networks can be one of the strategies to strengthen government transparency. The findings of this article indicate that the government transparency application needs to develop networks in all directions: intragovernmental, intergovernmental and collaborative networks. These three types of network in contrast with the popular belief that government transparency is interpreted only as a procedural activity to outside parties. A preliminary model in this article gives an overview about the arena of government transparency with multi-directional networks more comprehensively.

1989-01-01

A non-docking intraoperative radiation therapy electron beam applicator system for a linear accelerator has been designed to minimize the mechanical, electrical, and tumor visualization problems associated with a docking system. A number of technical innovations have been used in the design of this system. These include: (a) a new intraoperative radiation therapy cone design that gives a better dose uniformity in the treatment volume at all depths; (b) a collimation system which reduces the leakage radiation dose to tissues outside the intraoperative radiation therapy cone; (c) a non-docking system with a translational accuracy of 2 mm and a rotational accuracy of 0.5 degrees; and (d) a rigid clamping system for the cones. A comprehensive set of dosimetric characteristics of the intraoperative radiation therapy applicator system is presented

Application of positron annihilation induced auger electron spectroscopy to the study of surface chemistry

Weiss, A.H.; Yang, G.; Nangia, A.; Kim, J.H.; Fazleev, N.G.

1996-01-01

Positron annihilation induced Auger Electron Spectroscopy (PAES), makes use a beam of low energy positrons to excite Auger transitions by annihilating core electrons. This novel mechanism provides PAES with a number of unique features which distinguishes it from other methods of surface analysis. In PAES the very large collisionally induced secondary electron background which is present under the low energy Auger peaks using conventional techniques can be eliminated by using a positron beam whose energy is below the range of Auger electron energies. In addition, PAES is more surface selective than conventional Auger Spectroscopy because the PAES signal originates almost exclusively from the topmost atomic layer due to the fact that the positrons annihilating with the core electrons are trapped in an image correlation well just outside the surface. In this paper, recent applications of Positron Annihilation Induced Auger Electron Spectroscopy (PAES) to the study of surface structure and surface chemistry will be discussed including studies of the growth, alloying and inter-diffusion of ultrathin layers of metals, metals on semiconductors, and semiconductors on semiconductors. In addition, the possibilities for future application of PAES to the study of catalysis and surface chemistry will be outlined. (author)

-Federal information resources, linkages to data systems, and electronic delivery of information products. Development of this report proceeded in tandem with a GILS Profile development project that produced an Implementors Agreement in the voluntary standards process. The National Institute of Standards and Technology is now establishing a Federal Information Processing Standard referencing the GILS Profile Implementors Agreement and making mandatory its application for Federal agencies establishing locators for government information. Existing law and policy, as articulated in OMB Circular A-130, the Records Disposal Act, and the Freedom of Information Act, require agencies to create and maintain an inventory of their information systems and information dissemination products. Although compliance with these requirements varies greatly, the incremental cost of making those inventories accessible through GILS is expected to be minimal. Accordingly, participation in establishing and maintaining GILS may be accomplished as a collective effort executed within existing funds and authorities. OMB will publish in 1994 a Bulletin following on Circular A-130 that will specify agency responsibilities in GILS and set implementation schedules. A process for ongoing evaluation will also be established to evaluate the degree to which GILS meets the information needs of the public.

Production and applications of quasi-monoenergetic electron bunches in laser-plasma based accelerators

International Nuclear Information System (INIS)

Glinec, Y.; Faure, J.; Ewald, F.; Lifschitz, A.; Malka, V.

2006-01-01

Plasmas are attractive media for the next generation of compact particle accelerators because they can sustain electric fields larger than those in conventional accelerators by three orders of magnitude. However, until now, plasma-based accelerators have produced relatively poor quality electron beams even though for most practical applications, high quality beams are required. In particular, beams from laser plasma-based accelerators tend to have a large divergence and very large energy spreads, meaning that different particles travel at different speeds. The combination of these two problems makes it difficult to utilize these beams. Here, we demonstrate the production of high quality and high energy electron beams from laser-plasma interaction: in a distance of 3 mm, a very collimated and quasi-monoenergetic electron beam is emitted with a 0.5 nanocoulomb charge at 170 ± 20 MeV. In this regime, we have observed very nonlinear phenomena, such as self-focusing and temporal self-shortenning down to 10 fs durations. Both phenomena increase the excitation of the wakefield. The laser pulse drives a highly nonlinear wakefield, able to trap and accelerate plasma background electrons to a single energy. We will review the different regimes of electron acceleration and we will show how enhanced performances can be reached with state-of-the-art ultrashort laser systems. Applications such as gamma radiography of such electron beams will also be discussed

Definition and configuration of clinical content in an enterprise-wide electronic health record (EHR) implementation is highly complex. Sharing of data definitions across applications within an EHR implementation project may be constrained by practical limitations, including time, tools, and expertise. However, maintaining rigor in an approach to data governance is important for sustainability and consistency. With this understanding, we have defined a practical approach for governance of structured data elements to optimize data definitions given limited resources. This approach includes a 10 step process: 1) identification of clinical topics, 2) creation of draft reference models for clinical topics, 3) scoring of downstream data needs for clinical topics, 4) prioritization of clinical topics, 5) validation of reference models for clinical topics, and 6) calculation of gap analyses of EHR compared against reference model, 7) communication of validated reference models across project members, 8) requested revisions to EHR based on gap analysis, 9) evaluation of usage of reference models across project, and 10) Monitoring for new evidence requiring revisions to reference model.

The dream to control chemical reactions that are essential to life is now closer than ever to gratify. Recent scientific progress has made it possible to investigate phenomena and processes which deploy at the angstroms scale and at rates on the order femtoseconds. Techniques such as Ultrafast Electron Diffraction (UED) are currently able to reveal the spatial atomic configuration of systems with unit cell sizes on the order of a few nanometers with about 100 femtosecond temporal resolution. Still, major advances are needed for structural interrogation of biological systems like protein crystals, which have unit cell sizes of 10 nanometers or larger, and sample sizes of less than one micrometer. For such samples, the performance of these electron-based techniques is now limited by the quality, in particular the brightness, of the electron source. The current Ph.D. work represents a contribution towards the development and the characterization of electron sources which are essential to static and time-resolved electron diffraction techniques. The focus was on electron source fabrication and electron beam characterization measurements, using the solenoid and the aperture scan techniques, but also on the development and maintenance of the relevant experimental setups. As a result, new experimental facilities are now available in the group and, at the same time, novel concepts for generating electron beams for electron diffraction applications have been developed. In terms of existing electron sources, the capability to trigger and detect field emission from single double-gated field emitter Mo tips was successfully proven. These sharp emitter tips promise high brightness electron beams, but for investigating individual such structures, new engineering was needed. Secondly, the influence of the surface electric field on electron beam properties has been systematically performed for flat Mo photocathodes. This study is very valuable especially for state
