IT Security for Automation Systems – Motivations and Mechanisms
- In: atpi 01/2004, Oldenbourg Industrieverlag
, 2004
"... The protection of safety-critical and infrastructure systems (such as automation systems for utilities, but also for manufacturing plants) against electronic and communication network based attacks becomes more and more important. This paper examines how such safety-critical plants and automation sy ..."

systems can be secured against information system and network based attacks. Based on the defense-in-depth approach, a conceptional, generic security zone model for use in analysis and synthesis of a plant security architecture is proposed, and for each of its zones a survey of the available
Research Article Optimizing Nitrogen Management in Food and Energy Production and Environmental Protection
"... , and the environmental and management factors. This paper will synthesize the information generated from integrated nutrient management trials in subSaharan Africa and the Philippines. Management strategies based on an organic resources database and a dynamic soil-crop simulation model are used to ..."

-function in cardiovascular, endocrinological, and neurological systems. This study is to investigate the effects of EMs on the synthesis and secretion of vasoactive substances induced by advanced glycation end products in primary cultured human umbilical vein endothelial cells (HUVECs). Firstly, HUVECs were stimulated
SYNTHESIS OF ANION EXCHANGE/ACTIVATED CARBON FIBER HYBRID MATERIALS FOR AQUEOUS ADSORPTION OF TOXIC HEXAVALENT CHROMIUM BY
"... Hexavalent chromium, also known popularly as the “Erin Brockwich chemical”, has recently been identified as a carcinogen by ingestion. Unfortunately, it is present in drinking water supplies in United States. An effective, Point-of-Use (POU) based technology to remove Cr(VI) in tap water is urgently ..."

is urgently needed to protect human beings against this carcinogen. Due to the inadequate state-of-the-art technology for rapid, selective removal of Cr(VI), a unique hybrid activated carbon/anion exchange system (HACAX) has been developed for the first time in our group. HACAX was synthesized by methylation
IT-Security for Safety-Critical Automation Systems

, 1994
"... The fepA-entD and fes-entF operons in the enterobactin synthesis and transport system are divergently transcribed from overlapping promoters, and both are inhibited by the Fur repressor protein under iron-replete conditions. A plasmid harboring divergentfepA'-'phoA andfes-entF'-' ..."

Types for Atomicity: Static Checking and Inference for Java
"... Atomicity is a fundamental correctness property in multithreaded programs. A method is atomic if, for every execution, there is an equivalent serial execution in which the actions of the method are not interleaved with actions of other threads. Atomic methods are amenable to sequential reasoning, wh ..."

, which significantly facilitates subsequent analysis and verification. This article presents a type system for specifying and verifying the atomicity of methods in multithreaded Java programs using a synthesis of Lipton’s theory of reduction and type systems for race detection. The type system supports
