无源系统轻量级动态程序运行环境

无源系统能量紧缺导致系统难以长时间处于活动状态下工作,时常因能量不足而掉电.为保障程序完整执行,程序运行环境通常先让系统在低功耗状态从环境采集能量,然后切换至活动状态执行一个程序片段,循环往复直至完成.根据执行程序的不同策略,现有运行环境可分为两大类:一次执行和断点执行.前者在充能足够后一次性完整执行一个程序,适用于感知等轻量级程序;后者将程序拆分成若干片段,可间断执行,适用于长时间计算类程序.但在实际应用中,经常会出现以上两类程序混合执行的情况,使用任何现有运行环境都难以有效支持不同类型的程序混合执行,导致系统吞吐量下降.本文提出动态程序运行环境,根据不同的程序类型动态调整程序执行策略,全面支持现有两类程序高效率混合执行.我们优化了动态加载机制,实现了轻量化设计,降低了动态运行环境工作开销.我们在Intel WISP平台上对动态程序运行环境进行了实验评估,实验结果显示在多类程序混合执行时,动态运行环境的吞吐量比一次执行运行环境提高102.8％,比断点执行运行环境提高34％.

Would I lie to you? Self-serving lies and other-oriented lies told across different media

This study set out to investigate the type of media individuals are more likely to tell self-serving and other-oriented lies, and whether this varied according to the target of the lie. One hundred and fifty participants rated on a likert-point scale how likely they would tell a lie. Participants were more likely to tell self-serving lies to people not well-known to them. They were more likely to tell self-serving lies in email, followed by phone, and finally face-to-face. Participants were more likely to tell other-oriented lies to individuals they felt close to and this did not vary according to the type media. Participants were more likely to tell harsh truths to people not well-known to them via email.

Voices that cannot be heard: Can shyness explain how we communicate on Facebook versus face-to-face?

Social networking sites have gained popularity among all populations, especially young adults. Personality traits were found to be predictive of how individuals use social media. Therefore, this study sought to examine the association between shyness and self-disclosure to a Facebook friend as well as self-disclosure to a face-to-face friend. Two studies were conducted. The first study tested how shyness and social loneliness are related to self-disclosure to a Facebook friend to whom an individual talks most often. The second, follow-up study tested how shyness is related to self-disclosure to a Facebook friend to whom a person speaks to only though Facebook, and also to a face-to-face friend to whom the participants talk only face-to-face and never through Facebook. Participants were college students from a large research university in the United States. Study 1 found a negative association between shyness and self-disclosure to a Facebook friend. Study 2 found a negative association between shyness and self-disclosure to a face-to-face friend. The theoretical implications and limitations are discussed.     

IPv6协议下域名系统的扩展与实现

为了实现对IPv6协议的支持，需要对现有IPv4协议下的域名系统进行相应的扩展，以使其能在IPv6协议下正确地进行IP地址与域名的正向或反向解析。域名系统的扩展主要包括以下两方面：一是增加了两个新的资源记录AAAA和A6来存储IPv6地址，以实现域名到IPv6地址的正向解析；二是增加了两个新域：ip6.int和ip6．arpa，以实现IPv6地址到域名的反向解析。文中以著名的域名系统软件BIND为对象，以Linux操作系统Redhat9作为实验平台，详细介绍了基于Linux平台的域名系统对IPv6协议的扩展与实现，从而为实现IPv4到IPv6的平稳过渡打下了坚实基础。

Taking on motion‐artifacts evaluation in the VESA FPDM

Abstract— To date, there are no well‐established and few valid candidate methods to evaluate motion artifacts, although a number of organizations are working to come to agreement on ways to characterize, analyze, and quantify them. The LCD‐TV market has vested interest to improve performance with regard to motion artifacts, since: (1) LCDs are quite susceptible to many types of motion distortions, (2)most of its primary content has motion, and (3) they can be very noticeable and objectionable to even a casual viewer. This paper is an overview of motion artifacts, and the work of the VESA FPDM (flat panel display measurements standard) group both to update FPDM to FPDM3 and to standardize methods to evaluate motion artifacts.     

The electrical distribution network planning problem

In this paper we are dealing with the electrical distribution network planning problem where a network configuration has to be specified in order to meet demand, to satisfy the operating constraints, and to minimize investment, operating, and power–loss costs. The iterative procedure includes several heuristic algorithms to generate a radial network, to choose a set of open feeders to meet the reliability constraint, and to solve the reconfiguration problem in order to reduce the power–loss costs. Furthermore, in order to compare the reliability of potential solutions, a predictive reliability assessment measure is established.     

Naturalistic decision-making in expert badminton players

This paper reports on a study of naturalistic decision-making in expert badminton players. These decisions are frequently taken under time-pressured conditions, yet normally lead to successful performance. Two male badminton teams participated in this study. Self-confrontation interviews were used to collect data. Inductive data analysis revealed three types of intentions during a rally: to maintain the rally; to take the advantage; and to finish the point. It also revealed eight types of decision taken in this situation: to ensure an action; to observe the opponent's response to an action; to realize a limited choice; to influence the opponent's decision; to put pressure on an opponent; to surprise the opponent; to reproduce an efficient action; and to play wide. A frequent decision was to put pressure on the opponent. Different information and knowledge was linked to specific decisions. The results are discussed in relation to research that has considered naturalistic decision-making.
