A Key Private Re-Encryption Scheme To Secure And Privacy-Preserving Using Cam

In a remote Health monitoring system a client can set up a portable sensor to collect various physiological data to diagnosis himself. Such physiological data could then be sent to a central server which could then run a variety of web medical applications on these data to return timely advice to the client. Cloud-assisted mHealth monitoring could offer a great prospect to perk up the quality of healthcare services and potentially reduce healthcare costs there is a hesitant block in making this technology a reality. It is based on a new alternative of key private proxy re-encryption scheme in which the company only wants to achieve encryption once at the setup phase while shifting the rest computational tasks to the cloud without compromising privacy moreover reducing the computational and communication burden on clients and the cloud.
Application of coupled inductors in parallel inverter system

The difference of amplitude and phase between each module's output voltage can cause large loop-current among modules in parallel inverter system. Individual inductor connected between the inverter's output terminal and the load can restrain loop-current well with the disadvantage of reducing steady-state voltage accuracy of parallel system. Aiming at this problem, a new loop-current restraining method based on coupled inductors is proposed in this paper. Design principle of coupled inductors in parallel inverter system with two or more modules is also discussed. Simulation and experimental results in a 6 kVA two-module parallel inverter system prove that coupled inductors are better than individual one on the performance of restraining loop-current and have no impact on the steady-state voltage accuracy of parallel inverter system.
State of the art on subjective assessment of spatial sound quality

A new aim of sound technologies is spatial reproduction, which raises new questions about their quality assessment. This literature review deals with spatial audio quality: for audio coding, assessment is made through use of two mainly subjective ITU-R test methods. But, they are restricted to the evaluation of the overall quality. The finding, through various studies, of some features specific to surround sound drove us to wonder whether they can be included in a new quality assessment.
Extrapolation of radiated-emission test data from 3 meters to 10 meters

It is a concern of many EMC students how to extrapolate radiated-emission test data from 3 m SAC to 10 m SAC. According to various heights of the radiator and different polarization patterns of the electrical waves, this paper presents a discussion of the above problem in the 30-1000 MHz frequency range. Accurate results have been obtained, which are valuable to practical measurements.
Grappling Spacecraft

This article provides a survey overview of the techniques, mechanisms, algorithms, and test and validation strategies required for the design of robotic grappling vehicles intended to approach and grapple free-flying client satellites. We concentrate on using a robotic arm to grapple a free-floating spacecraft, as distinct from spacecraft docking and berthing, where two spacecraft directly mate with each other. Robotic grappling of client spacecraft is a deceptively complex problem: It entails designing a robotic system that functions robustly in the visually stark, thermally extreme orbital environment, operating near massive and extremely expensive yet fragile client hardware, using relatively slow flight computers with limited and laggy communications. Spaceflight robotic systems are challenging to test and validate prior to deployment and extremely expensive to launch, which significantly limits opportunities to experiment with new techniques. These factors make the design and operation of orbital robotic systems significantly different from those of their terrestrial counterparts, and as a result, only a relative handful of systems have been demonstrated on orbit. Nevertheless, there is increasing interest in on-orbit robotic servicing and assembly missions, and grappling is the core requirement for these systems. Although existing systems such as the Space Station Remote Manipulator System have demonstrated extremely reliable operation, upcoming missions will attempt to expand the types of spacecraft that can be safely and dependably grappled and berthed. Expected final online publication date for the Annual Review of Control, Robotics, and Autonomous Systems, Volume 5 is May 2022.

Thrombotic Microangiopathy Score as a New Predictor for Neurologic Outcome in Patients Undergoing Targeted Temperature Management After Out-of-hospital Cardiac Arrest

Background: Given the morphological characteristics of schistocytes, thrombotic microangiopathy (TMA) score can be beneficial as it can be quickly and serially measured without additional effort or costs. This study aimed to investigate whether the serial TMA scores until 48 h post admission are associated with clinical outcomes in patients undergoing targeted temperature management (TTM) after out-of-hospital cardiac arrest (OHCA). Methods:We retrospectively evaluated a cohort of 185 patients using a prospective registry. We analyzed the TMA score at admission and after 12, 24, and 48 hours. The primary outcome measures were poor neurologic outcome at discharge and 30-day mortality. Results:Increased TMA scores at all measured time points were independent predictors of poor neurologic outcomes and 30-day mortality, with the TMA score at time-12 showing the strongest correlation (OR, 3.008; 95% CI, 1.707–5.3; p=0.001 and HR, 1.517; 95% CI, 1.196–1.925; p=0.001.Specifically, TMA score ≥2 at time-12 was closely associated with increased predictability of poor neurologic outcome (OR, 6.302; 95% CI: 2.841–13.976; p<0.001) and 30-day mortality (HR, 2.656; 95% CI: 1.675–4.211; p<0.001). Conclusions: Increased TMA scores predicted the neurologic outcome and 30-day mortalityin patients undergoing TTM after OHCA. In addition to the benefit of being quickly and serially measured by using an automated hematology analyzer without additional effort or costs, this finding indicates that the TMA score may be a helpful tool for rapid risk stratification and identification of the need for intensive care in patients with ROSC after OHCA.
Signal compression in radar using FPGA

We present the hardware implementation of radar real time processing procedures using a simple, fast technique based on FPGA (Field Programmable Gate Array) architecture. This processing includes different window procedures during pulse compression in synthetic aperture radar (SAR). The radar signal compression processing is realized using matched filter, and classical and novel window functions, where we focus on better solution for minimum values of side-lobes. The proposed architecture exploits the parallel computing resources of FPGA devices to achieve better computation speed. Experimental investigations have shown that the best results for pulse compression performance have been obtained using atomic functions, improving the performance of the radar system in the presence of noise, obtaining small degradation in range resolution. Implementation of the signal processing in the radar system for real time mode is discussed here and the effectiveness of the proposed hardware architecture has been justified.
Augmented reality for non-rigid surfaces

Augmented Reality (AR) is the process of integrating virtual elements in reality, often by mixing computer graphics into a live video stream of a real scene. It requires registration of the target object with respect to the cameras. To this end, some approaches rely on dedicated hardware, such as magnetic trackers or infra-red cameras, but they are too expensive and cumbersome to reach a large public. Others are based on specifically designed markers which usually look like bar-codes. However, they alter the look of objects to be augmented, thereby hindering their use in application for which visual design matters. Recent advances in Computer Vision have made it possible to track and detect objects by relying on natural features. However, no such method is commonly used in the AR community, because the maturity of available packages is not sufficient yet. As far as deformable surfaces are concerned, the choice is even more limited, mainly because initialization is so difficult. Our main contribution is therefore a new AR framework that can properly augment deforming surfaces in real-time. Its target platform is a standard PC and a single webcam. It does not require any complex calibration procedure, making it perfectly suitable for novice end-users. To satisfy to the most demanding application designers, our framework does not require any scene engineering, renders virtual objects illuminated by real light, and let real elements occlude virtual ones. To meet this challenge, we developed several innovative techniques. Our approach to real-time registration of a deforming surface is based on wide-baseline feature matching. However, traditional outlier elimination techniques such as RANSAC are unable to handle the non-rigid surface's large number of degrees of freedom. We therefore proposed a new robust estimation scheme that allows both 2–D and 3–D non-rigid surface registration. Another issue of critical importance in AR to achieve realism is illumination handling, for which existing techniques often require setup procedures or devices such as reflective spheres. By contrast, our framework includes methods to estimate illumination for rendering purposes without sacrificing ease of use. Finally, several existing approaches to handling occlusions in AR rely on multiple cameras or can only deal with occluding objects modeled beforehand. Our requires only one camera and models occluding objects at runtime. We incorporated these components in a consistent and flexible framework. We used it to augment many different objects such as a deforming T-shirt or a sheet of paper, under challenging conditions, in real-time, and with correct handling of illumination and occlusions. We also used our non-rigid surface registration technique to measure the shape of deformed sails. We validated the ease of deployment of our framework by distributing a software package and letting an artist use it to create two AR applications.

Exploring national culture in software development practices

[Abstract]: The software development industry has become globalised. Trends which have contributed to globalisation include the maturation of software industries in developing countries, collaborative teams covering extended geographic areas, and migration of computing professionals. This paper analyses the Australian computer professional workforce and determines that 40 percent of computing professionals were not born in Australia. Results from surveys about adoption of software development best practice conducted in 16 countries are then summarised and analysed using Hofstede's cultural dimensions. The discussion considers the efficacy of the concept 'national culture' in light of the analysis and concludes that information systems researchers need to reconsider what national culture is, and how it can best be measured.
Multicriteria analysis of health, comfort and energy efficiency in buildings

In order to comply with sustainable development policy, the minimum that buildings should achieve are a healthy, comfortable and energy-efficient environment. Criteria for individually assessing each of the many criteria are known: the occupant's perceived health; the provided thermal, visual and acoustical comfort; and the indoor air quality and energy efficiency. A methodology is proposed to perform a global evaluation of a building with regard to all these criteria. This methodology is applied to a sample of 96 apartment buildings and 64 office buildings to determine a set of best buildings and a set of buildings that are not acceptable in terms of comfort, perceived health and energy use. Some significant differences between these two groups of buildings are presented. The very existence of the first set shows that it is possible to design and build office and apartment buildings that are simultaneously energy efficient, healthy and comfortable. Pour être conforme à une politique de développement durable, les bâtiments doivent être, au minimum, sains, confortables et économes en énergie. On connaît les critères d'évaluation individuelle de chacun des nombreux paramètres en jeu: santé perçue par l'occupant, confort thermique, visuel et acoustique, qualité de l'air intérieur et faible consommation d'énergie. Cet article expose une méthodologie qui permet d'effectuer une évaluation globale d'un bâtiment eu égard à tous ces critères. Elle est appliquée à un échantillon de 96 immeubles d'habitation et 64 immeubles de bureaux afin de déterminer un groupe des meilleurs immeubles et un groupe d'immeubles qui ne sont pas acceptables sur les plans du confort, de la santé perçue et de l'utilisation de l'énergie. Quelques unes des différences significatives entre ces deux groupes d'immeubles sont présentées. L'existence même du premier groupe montre qu'il est possible de concevoir et de construire des immeubles de bureaux et d'habitation qui sont à la fois économes sur le plan de l'énergie, sains et confortables. Mots clés: évaluation des bâtiments, confort, économie d'énergie, santé, environnement intérieur, analyse multicritère, perception des occupants, satisfaction
Frequency stirring: An alternate approach to mechanical mode-stirring for the conduct of electromagnetic susceptibility testing

Abstract : This study summarizes the results of an experiment designed to determine the effectiveness of using frequency stirring to provide field homogeneity in a reverberation chamber. Frequency stirring is accomplished by up-converting band limited white Gaussian noise to microwave frequencies and thus exploits both the high mode densities achievable in a narrow bandwidth at microwave frequencies and the pseudo-statistical nature of the reverberation chamber's eigenmodes. The ultimate goal is to replace the mechanical stirring devices currently used in reverberating chambers with an equivalent electronic eigenmode stirrer. In addition, an expression for the net Q of a reverberation chamber is developed which includes the effects of antenna loading; methods for predicting the homogeneity of the resulting fields in the chamber after application of the frequency stir technique are proposed; and a theoretical basis for interpreting fringe power density levels, cross sections, and shielding effectiveness measurements is also given.
C-shield parylene allows major weight saving for EM shielding of microelectronics

Parylene is a conformal polymer film that has been used as a protective conformal coating for more than 25 years. It provides environmental and dielectric isolation in a variety of applications, industrial and automotive sensors, electronic circuits, hybrids, various medical substrates, and is also used extensively for corrosion protection and electrical insulation of ferrites and magnets. The most important performance specifications for a conformal coating are (1) uniformity and completeness of coverage, and (2) physical, electrical, chemical, mechanical, and barrier properties. Parylene offers significant performance capabilities in both of these areas. As a nonsolvent based coating, parylene is not affected by volatile organic compound (VOC) restrictions, and it is not implicated in the ozone depletion concerns of the Montreal Protocol and other environmental legislation. The parylene vacuum condensation process is now also capable of producing a dissipative parylene 'C-shield' that allows packaging of microelectronics with both the environmental protection offered by parylene and the dissipation of undesired stray EM radiation. This eliminates encapsulation with metal boxes and allows major cost and weight savings.
Transforming the Retail Industry: Potential and Challenges with RFID Technology

This article provides a thorough overview of radio-frequency identification technology, or RFID, and its benefits for the retail industry. Those benefits include operational efficiencies and improvements, supply-chain visibility, increased collaboration with business partners, and seamless replenishment. But the authors suggest that RFID will not become implemented universally until costs come down, compatibility, reliability, privacy and hardware problems are resolved. They describe the nature of these challenges in detail, as well as the importance of universal acceptance of the technology across virtually all retailers and suppliers.
Carbon capture and storage in the U.S. : a sinking climate solution

Coal-fired power plants produce half of the United States' electricity and are also the country's largest emitter of carbon dioxide, the greenhouse gas responsible for climate change. Carbon Capture and Storage (CCS) is a proposed technological solution that will sequester CO2 in the ground. Proponents of CCS have framed it as a "clean coal technology" and broadcast the story that it will solve both our dependence on coal and prevent future climate change impacts. However, the technology is not a practicable solution for climate change, even with the most generous timetables and goals for atmospheric carbon. It cannot be scaled in time, costs too much, has serious environmental risks, and will face public resistance. Yet, CCS remains a part of future U.S. energy policy because the coal and electric utility industries have funded an attractive message and story for it. Environmental advocacy organizations are unable to create an effective counter-story because they are split into two coalitions. Therefore, the public is not mobilized and there is no incentive for legislators to challenge coal and
Challenging Practice: an approach to Cooperative Analysis

Cooperative Analysis takes as its starting point the tradition of user-involvement in system development in Scandinavia, especially cooperative design. It points to the mismatch in this tradition between analysis as passive observation and design as cooperative intervention. Cooperative Analysis is conducted cooperatively and through intervention in the practice beeing analysed. Cooperative Analysis is seen as part of a large development process, and is thus seen as facilitating taking action in order to bring about change. The primary approach is one of provoking current practice through concrete experience. Provocation serves the purpose of calling forth hitherto taken-for-granted issues as well as it challenges the existing practice to investigate its dynamics and open up for new possibilities. As two specific means to this end, the book introduces an approach of using artifacts (e.g. commercially available products, prototypes, and mock-ups) to trigger new understandings of current practice and it introduces dilemma games to challenge current practice by exposing it to some of its inherent dilemmas.
Timber Harvesting with Variable Prices and Costs

In its history, IIASA's Forestry (FOR) Project has produced a number of models casting future scenarios of the forest industry. At the same time, FOR has also been involved in ecosystem modeling and forest resource assessments. Linking the processes of forest industry development to its resource use will be of particular interest in the activity that FOR started this year - Information Technology and Structural Change of the Global Forest Sector. In this particular work, carried out in cooperation with the Finnish Forest Research Institute in Helsinki, Markku Penttinen establishes a decision tool that will help in endeavoring to answer the question of whether information technology will or will not improve the sustainability of the worlds forest resources.
Generating expression in synthesized speech

This document is a revised version of my master's thesis, submitted in May, 1989 to the Media Arts and Sciences Section of the Department of Architecture, at the Massachusetts Institute of Technology. The revisions are as follows: grammatical and factual corrections, particularly in Chapter 2; revised table formats to better conform to IPA standards; the addition of a table in Appendix B; and the addition of Appendix C1 containing pitch tracks of, energy tracks and spectrograms of synthesized speech. The grammatical and factual revisions were contributed by Susan E. Brennan of Hewlett{Packard Laboratories in Palo Alto in the summer of 1989, and by Professor Kenneth N. Stevens, of the Massachusetts Institute of Technology in the fall. The document examines the proposal that a ect can be reproduced in synthesized speech by imitating the e ects of emotion in human speech. A program, the A ect Editor, was constructed to systematically vary the in uence of the speech correlates of emotion and so direct the synthesis of the intended a ect. The task raised and explored questions about: the appropriate representation of an emotion's e ect on speech; the appropriate mapping from such a representation to synthesizer parameters; and the synthesizer features needed to generate convincing a ect. The true test of synthesized a ect is perceptual. An experiment was performed to test whether the intended a ect was reproduced by the A ect Editor. The results con rmed that the intended a ect was recognized, and furthermore, bore out predictions about areas of confusion. This work supports the conclusion that a ect can be generated and systematically controlled in synthesized speech. The limits of the A ect Editor indicate that more research is needed into the determination of useful taxonomies of emotion and of the speech correlates of emotion. Better synthesizers are also needed, to enable more precise testing and development, and eventually, real{time generation of a ect in synthesized speech. One audio cassette tape accompanies this document. Side A contains: (1) seventeen utterances from which gures in this document are generated and (2) the stimuli used in the experiment described in Chapter 6 (30 unique utterances). Side B contains: (1) sentences synthesized with varied a ect speci cations (2) seventeen utterance sequences | one per A ect Editor parameter | in which parameters values are cycled from low to high.

Stability characterizations of rigid body contact problems with coulomb friction

This paper formally introduces several stability characterizations of systems of rigid bodies initially at rest and in unilateral contact with dry friction. These characterizations, weak stability and strong stability (and their complements), arise naturally from the dynamic model of the system, formulated as a complementary problem. Using the tools of complementarity theory, these characterizations are studied in detail to understand their properties and to develop techniques to identify the stability classifications of general systems subjected to known external loads.
