We present a novel dynamic network interdiction model that accounts for interactions between an interdictor deploying resources on arcs in a digraph and an evader traversing the network from a designated source to a known terminus, wherein the agents may modify strategies in selected subsequent periods according to respective decision and implementation cycles. For the resulting minimax model, ...

Measurements of the iron regulatory hormone hepcidin by various methodologies and laboratories are not harmonized. As a result different numeric results are obtained for the same clinical sample. We investigated whether better agreement between plasma hepcidin methods can be achieved by harmonization. Native plasma pools (n = 11) of a variety of hepcidin concentrations and blank plasma spiked w...

The FASD study gathered 1330 answers about fun and software development from open source developers as well as 114 answers from programmers working in commercial software projects. The analysis of these data proves that fun plays an important role when software developers decide to get engaged in an open source project. Moreover, the comparison of the answers gives evidence for the hypothesis t...

This article describes an algorithm for defining the precise, objective, repeatable and unambiguous segmentation of cells in images of the corneal endothelium. This issue is important for clinical purposes, because the quality of the grid cells is assessed on the basis of segmentation. Other solutions, including commercial software, do not always mark cell boundaries along lines of lowest brigh...

Concern has been rising about the health of the U.S. commercial real estate market and any impact it may have on financial markets and institutions. It is too early to judge the full extent of any problems, but commercial real estate financing has been shaken by the financial market turmoil associated with recent residential mortgage defaults. The spreads of commercial mortgage-backed securitie...

The ever-increasing number of fielded Data Mining applications is evidence that the technology works and produces added value in a variety of business areas. Most of the research-lab generated algorithms have found their way under various guises in a number of commercial software packages. When considering the use of Data Mining, the average business user is now faced with a plethora of DM soft...

Users should be involved in the interactive systems development. However, involving users is often difficult and rare, especially in the product development context, referring to the development of commercial software products or systems. This paper critically examines user involvement in the cultural context of three software product development organizations. User involvement is indirect and ...

Commercial-Off-The-Shelf (COTS) software is increasingly being suggested for use in systems development, for reasons including cost, functionality, useability, testedness, availability of support and upgrades. At the same time, standards for use of software in safetyrelated systems are becoming increasingly stringent. This paper examines the issue of providing safety assurance for systems invol...

Digital forensic analysts may find their task complicated by any of more than a dozen commercial software packages designed to irretrievably erase files and records of computer activity. These counter-forensic tools have been used to eliminate evidence in criminal and civil legal proceedings and represent an area of continuing concern for forensic investigators. In this paper, we review the per...
