作者： l.u Fagui,l. Shengwen,Xie Ran,l.o Chunwei School.of Comp.ter Science & Engineering South China University of Technol.gy Guangzhou,p. R. China

With the continuous devel.p.ent of embedded technol.gy,embedded ap.l.cations are becoming increasingl. p.p.l.r in dail. l.ves,and resp.ctivel. embedded software is in great demand. As a resul.,how to p.ofil. embedded software to guarantee its qual.ty becomes a focus of attention. This p.p.r focuses on this issue. It anal.zes current methods of embedded software p.ofil.ng and their defects,and then p.op.ses a l.w-overhead and more accurate method. It al.o p.rforms some strict exp.riments to p.ove that it is effective and much better than current methods.

Modeling and Analysis of Guessing Attacks in Strand Spaces

作者： Shigong l.ng Wenjun l.o Changgen p.n Xiang l. Inst. of Comp.ter Software and Theory Guizhou University Guiyang 550025 p. R. China

＜正＞This p.p.r p.esents an extension of strand sp.ces that can reason about various forms of guessing attacks on the authenticated p.otocol.based on p.ssword. The sequences of attacker actions corresp.nding to the forms of guessing attacks are model.d comp.sition strands. We p.esent a systematic way of anal.zing a p.otocol.for guessing attacks within our framework. In p.rticul.r, we argue whether randoml. guessing val.es can be infeasibl. using the concep. of threshol. p.obabil.ty which is a measure of the system’s tol.rance. We have il.ustrated these methods on Gl.S p.otocol.as an examp.e.

A DS-UWB Interpath Interference Suppression Scheme Based on ...

第八届国际信号处理国际会议

作者： Shenyuan Yang Qian Yin Xiaoyan Bi Zheng l. Col.ege of Information and Communications Engineering Harbin Engineering University Harbin 150001 p. R. China

＜正＞By taking advantage of the good correl.tion p.op.rties of sp.eading codes, RAKE receiver can resol.e mul.ip.th comp.nents with p.op.gation del.y difference l.rger than one chip.p.riod. However, for DS-UWB systems, the good correl.tion p.op.rties are missing due to the use of l.w p.ocessing gains to sup.ort high data rates. Hence, the interp.th interference （Ip.） becomes an imp.rtant factor to system p.rformance. In this p.p.r, the maximum l.kel.hood sequence estimation （Ml.E） is used to combat Ip.. Ml.E formul.tions for DS-UWB signal. are derived and a reduced comp.exity RAKE-Ml.E structure is p.op.sed. Various simul.tions are carried out to assess p.rformance of the p.op.sed structure. Resul.s obtained indicate that significant p.rformance gains over conventional.RAKE receiver can be achieved.

背景:人体老龄化进程中,下肢肌肉力量会随着年龄的增长呈现显著的生理性下降,久坐、跌倒恐惧、年龄与下肢肌力之间可能存在一定关联,但它们之间的影响路径与效应关系尚不明确。目的:探究社区老年人久坐和下肢肌肉力量之间的关系,并探讨跌倒恐惧和年龄在上述两者关系中的作用。方法:共招募331名60岁及以上的上海市社区老年人。采用问卷调查法收集基本信息、人口学资料等;采用国际身体活动问卷-短卷评估久坐时间,采用30 s坐站测试测量下肢肌力,采用中文版国际跌倒效能量表测评跌倒恐惧。对数据进行描述统计、相关分析、基于回归的路径分析和中介效应检验。结果与结论:最终以318名老年人[78.9%为女性,平均年龄(67.8±5.5)岁]的有效数据纳入分析,其中久坐时间≥3 h的185名,p.0.01),下肢肌力和久坐(p.0.01)、跌倒恐惧(p.0.001)均呈负相关关系。②久坐显著负向预测下肢肌力(β=-0.125,p.0.05),久坐显著正向预测跌倒恐惧(β=0.182,p.0.01);跌倒恐惧显著负向预测下肢肌力(β=-0.293,p.0.001)。③跌倒恐惧在久坐和下肢肌力之间起中介作用(β=-0.053,95%CI:-0.100至-0.018)。④久坐对跌倒恐惧的预测效应具有统计学意义(β=0.164,p.0.01),这说明年龄调节了久坐对跌倒恐惧的影响。
