Developing trusted softwares has become an important trend and a natural choice in the development of software technology and applications. At present, the method of measurement and assessment of software trustworthiness cannot guarantee safe and reliable operations of software systems completely and effectively. Based on the dynamical system study, this paper interprets the characteristics of be- haviors of software systems and the basic scientific problems of software trustworthiness complexity, analyzes the characteristics of complexity of software trustworthiness, and proposes to study the soft- ware trustworthiness measurement in terms of the complexity of software trustworthiness. Using the dynamical statistical analysis methods, the paper advances an invariant-measure based assessment method of software trustworthiness by statistical indices, and hereby provides a dynamical criterion for the untrustworthiness of software systems. By an example, the feasibility of the proposed dynamical statistical analysis method in software trustworthiness measurement is demonstrated using numerical simulations and theoretical analysis.

Dynamical characteristics of software trustworthiness and their evolutionary complexity

Science in China(Series F) 2009年第8期52卷 1328-1334页

作者： zheng zhiming MA ShiLong LI Wei WEI Wei JIANG Xin ZHANG ZhanLi GUO BingHui Key Laboratory of Mathematics Informatics and Behavioral Semantics Ministry of Education Beihang University Beijing 100191 China State Key Laboratory of Software Development Environment Beihang University Beijing 100191 China School of Mathematical Sciences Peking University Beijing 100871 China

Developing trusted softwares has become an important trend and a natural choice in the development of software technology and applications, and software trustworthiness modeling has become a prerequisite and necessary means. To discuss and explain the basic scientific problems in software trustworthiness and to establish theoretical foundations for software trustworthiness measurement, combining the ideas of dynamical system study, this paper studies evolutionary laws of software trustworthiness and the dynamical mechanism under the effect of various internal and external factors, and proposes dynamical models for software trustworthiness, thus, software trustworthiness can be considered as the statistical characteristics of behaviors of software systems in the dynamical and open environment. By analyzing two simple examples, the paper explains the relationship between the limit evolutionary behaviors of software trustworthiness attributes and dynamical system characteristics, and interprets the dynamical characteristics of software trustworthiness and their evolutionary complexity.

High performance columnar-like Fe2O3@carbon composite anode via yolk@shell structural design

Conversion-type reaction anode materials with high specific capacity are attractive candidates to improve lithium ion batteries(LIBs), yet the rapid capacity fading and poor rate capability caused by drastic volume change and low electronic conductivity greatly hinder their practical applications. To circumvent these issues, the successful design of yolk@shell Fe2 O3@C hybrid composed of a columnar-like Fe2O3 core within a hollow cavity completely surrounded by a thin, self-supported carbon(C) shell is presented as an anode for high-performance LIBs. This yolk@shell structure allows each Fe2O3 core to swell upon lithiation without deforming the carbon shell. This preserves the structural and electrical integrity against pulverization, as revealed by in situ transmission electron microscopy(TEM) measurement. Benefiting from these structural advantages, the resulting electrode exhibits a high reversible capacity(1013 m Ah g-1 after80 cycles at 0.2 A g-1), outstanding rate capability(710 m Ah g-1 at 8 A g-1) and superior cycling stability(800 m Ah g-1 after 300 cycles at 4 A g-1). A Li-ion full cell using prelithiated yolk@shell Fe2 O3@C hybrid as the anode and commercial Li CoO2(LCO) as the cathode demonstrates impressive cycling stability with a capacity retention of 84.5% after 100 cycles at 1 C rate, holding great promise for future practical applications.

当将《灵剑子》一书定位为北宋时期的作品时 ,其历史地位就更为特殊 ,在道教的文化发展上有着承先启后的作用 ,处于唐代道教之后 ,南宋各种新道派成立之期 ,介于符与丹道的传承之间。此一时期道教可以说是支派繁衍与驳杂混乱 ,除了符科教道法特别兴盛外 ,在道教的思想与理论的建构上有不少的突破与建树 ,尤其在道家的修炼术上 ,从唐代的外丹术转向于内修的锻炼术 ,体内炼丹的思想大为流行 ,在张伯端的《悟真篇》之前 ,类似“内丹”的修行方法与技术已层出不穷 ,不少道士符与内修是同时并进。《灵剑子》正好是道教内丹学说与理论成型之前的作品 ,反映了道教在性命修持上的长期努力 ,为南宋、金、元修炼内丹道派的兴起奠定了基础。在历史的发展过程中 ,道教的各种教派在文化上是互相杂揉的 ,追求的是炼养成仙的目标 ,至于五花八门的各种功法 ,可以各取所需与各自发展。在唐宋内丹思潮的影向下 ,导致道教生态环境的转变 ,《灵剑子》即是这种转变下的一种形态 ,吸收了由行气、胎息而来的内丹功法 ,但就其宗教本质来说 ,内修只是其成仙的一种手段而已 ,仍着重于阴骘的功德圆满上。
