Assurance BasedDevelopment (ABD) is a novel approach to the synergistic construction of critical soware systems and their assurance arguments. InABD, theneed for assurance drives a unique process synthesis mechanism that results in a detailed process for building both soware and an argument demonstrating its fitness for use in given operating contexts. In this paper, we introduce the ABD proc...

ABSTRACT We present a method for lustering do uments and extra ting topi words of ea h luster using a probabilisti graphi al model. We maximize the likelihood of the model with the Expe tation Maximization algorithm. Our experiments demonstrate that the latent variables of the model an be seen as lusters of do uments and terms.

Highly conductive free standing polypyrrole (PPy) films were prepared by a novel freezing interfacial polymerization method. The films exhibit metallic luster and electrical conductivity up to 2000 S cm(-1). By characterizing with SEM, FTIR, Raman and XRD, the high conductivity is attributed to the smooth surface, higher conjugation length and more ordered molecular structure of PPy.

CASE SYNOPSIS In September 1996, a new evidence tool was used for the first time in a United States courtroom. Mitochondrial DNA (mtDNA) evidence was introduced in a Tennessee murder prosecution against twenty-seven-year-old Paul Ware. Without the mtDNA results there was only circumstantial evidence pointing to Ware as the suspect in the rape and murder of a fouryear-old girl. The defense claim...

So‰ware engineering is at the core of the digitalization of society. Ill-informed decisions can have major consequences, as made evident in the 2017 government crisis in Sweden, originating in a data breach caused by an outsourcing deal made by the Swedish Transport Agency. Many Government Agencies (GovAgs) in Sweden are rapidly undergoing a digital transition, thus it is important to overview ...
