2. 1. A Quantitative Approach to Computer Security from a Dependability Perspective

   Author : Erland Jonsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; intrusions; computers; modelling; vulnerability; dependability evaluation; experimentation; terminology; operational security; reliability; concepts; measures;

   Abstract : Security and dependability represent two very important attributes of modern computer systems, especially in the light of the increasing complexity and criticality of these systems. These two disciplines have traditionally been treated separately, although lately some attempts have been made to integrate them. READ MORE

4. 2. Track circuits’ robustness : Modeling, measurement and simulation

   Author : Emilio Rodriguez; Ajit Kumar Verma; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Track circuit; Relay; False positive signals; Signalling in railway; Modelling; Simulation; Testing; Robustness; Interoperability; Reliability; Railway Infrastructure; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Abstract : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. READ MORE

5. 3. Models for Estimation of Software Faults and Failures in Inspection and Test

   Author : Per Runeson; Institutioner vid LTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; failures; usage based testing; usage model; statistical testing; faults; capture-recapture; inspections; software quality; software reliability; experiments; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

   Abstract : In software engineering, the quality of software and in particular the software reliability has to be controlled and improved. Hence there is a need for measuring and controlling the number and appearance of software faults and failures. READ MORE

6. 4. Assessing future effects on lake ecosystem resilience using data analysis and dynamic modelling : Modelling the effects of extreme weather events and climate warming on lakes

   Author : Jorrit P. Mesman; Bastiaan W Ibelings; Stéphane Goyette; Don C Pierson; Karsten Rinke; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extreme events; Storms; Modelling; Climate change; Thermal structure; Phytoplankton;

   Abstract : Extreme weather events can have short-term and long-term effects on lake thermal structure, nutrient dynamics, and community composition. Moreover, changes in lake variables induced by global climate change may influence the response and recovery of lake ecosystems to extreme weather events. READ MORE

7. 5. The development and implementation of software for palaeoenvironmental and palaeoclimatological research : the Bugs Coleopteran Ecology Package (BugsCEP)

   Author : Philip Buckland; Roger Engelmark; Geoffrey Lemdahl; Paul Sinclair; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; Quaternary geology; environmental archaeology; quaternary science; Coleoptera; beetles; database; environmental reconstructions; climate reconstructions; software; Mutual Climatic Range; MCR; palaeoentomology; Kvartärgeologi; Archaeology; Arkeologi; Archaeology; arkeologi;

   Abstract : This thesis documents the development and application of a unique database orientated software package, BugsCEP, for environmental and climatic reconstruction from fossil beetle (Coleoptera) assemblages. The software tools are described, and the incorporated statistical methods discussed and evaluated with respect to both published modern and fossil data, as well as the author’s own investigations.
