一个新的门限多重代理多重签名方案

In the Paper, we proposed a threshold mult- proxy multi-signature with share verification.In the scheme,a subset of original signers allows a designated group to proxy signers to sign on behalf of the original group, A message m has to be signed of proxy signers who can represent the proxy group. Then, the proxy signature is sent to the verifier group.A subset of verifiers in the verifier group can also represent the group to authenticate the proxy signature.In othe words,some threshold values will be given to indicate the number of persons to represent a group to authorize the signing capability or to sign a messagye or to verify the proxy signature.     

E-field ferroelectric sensors: Modeling and simulation [Instrumentation Notes]

In this article, a novel approach to sensing static electric fields has been presented. The approach is extremely interesting due to the low cost of the technology and the simplicity of the architecture. The purpose of the article is to highlight the strategic role of behavioral models in the development and design of E-field sensors. It is important to observe that simulation results must always be supported by experimental evidence to confirm the predicted behaviors. A good solution to perform a reliable investigation, if allowed, is to model the main blocks of the system separately and at the same time to experimentally assess their real behavior to confirm theoretical expectations.     

Reputation based selfishness prevention techniques for mobile ad-hoc networks

Mobile ad-hoc networks require nodes to cooperate in the relaying of data from source to destination. However, due to their limited resources, selfish nodes may be unwilling to forward packets, which can deteriorate the multi-hop connectivity. Different reputation-based protocols have been proposed to cope with selfishness in mobile ad-hoc networks. These protocols utilize the watchdog detection mechanism to observe the correct relaying of packets, and to compile information about potential selfish nodes. This information is used to prevent the participation of selfish nodes in the establishment of multi-hop routes. Despite its wide use, watchdog tends to overestimate the selfish behavior of nodes due to the effects of radio transmission errors or packet collisions that can be mistaken for intentional packet drops. As a result, the availability of valid multi-hop routes is reduced, and the overall performance deteriorates. This paper proposes and evaluates three detection techniques that improve the ability of selfishness prevention protocols to detect selfish nodes and to increase the number of valid routes.     

Preparing technical communication students to play a role on the translation team

Technical communicators need to be prepared for the challenges of international communication. This tutorial focuses on the need for technical communication faculty to prepare students to be skilled intercultural communicators and to play a role on the translation team. The tutorial begins with a discussion of the importance of writing for translation in the international workplace and then presents specific assignments designed to instruct students in intercultural communication and give them experience writing for translation. In addition to introducing students to the cultural issues that impact the creation of documentation for international audiences, these assignments also serve to reinforce core skills recognized as vital to professional success in the field of technical communication. Taken together, these assignments can be used as the basis for a course in international technical communication. An appendix to the tutorial includes numerous resources available to faculty who want either to develop a course in international technical communication or to include some of the assignments in existing technical communication courses.     

Using Nonadditive Fuzzy Integral to Assess Performances of Organizational Transformation Via Communities of Practice

Organizational transformations have been widely adopted by firms who wish to improve their competitive advantage to be better prepared to face external challenges. This research has chosen Communities of Practice (CoPs) as the subject of discussion for an assessment model to reform organizations that undertake CoPs for collective knowledge to enhance their core competencies. Given the interrelationships between criteria, this research uses the nonadditive fuzzy integral to develop a framework for the CoPs performance assessment. The purposes of this paper are to identify the key dimensions/criteria in the CoPs, to use fuzzy logic method to analyze the relative importance of each criterion, and to rank the criteria so that proper resources can be allocated while managing the CoPs. Through interviews with experts, four strategy alternatives and 16 criteria along four dimensions are generated. A survey of the CoPs practitioners is then conducted to compare the results of each criterion. The results will not only help organizations that intend to initiate changes via the CoPs activities to decide the ranking of their appraisal criteria, but it can also assist them in guiding the behavior of their staff while effectively monitoring and improving the performances of the CoPs

Use of induced acceleration to quantify the (de)stabilization effect of external and internal forces on postural responses

Due to the mechanical coupling between the body segments, it is impossible to see with the naked eye the causes of body movements and understand the interaction between movements of different body parts. The goal of this paper is to investigate the use of induced acceleration analysis to reveal the causes of body movements. We derive the analytical equations to calculate induced accelerations and evaluate its potential to study human postural responses to support-surface translations. We measured the kinematic and kinetic responses of a subject to sudden forward and backward translations of a moving platform. The kinematic and kinetics served as input to the induced acceleration analyses. The induced accelerations showed explicitly that the platform acceleration and deceleration contributed to the destabilization and restabilization of standing balance, respectively. Furthermore, the joint torques, coriolis and centrifugal forces caused by swinging of the arms, contributed positively to stabilization of the Center of Mass. It is concluded that induced acceleration analyses is a valuable tool in understanding balance responses to different kinds of perturbations and may help to identify the causes of movement in different pathologies.
