The history of information systems research is steeped in a quest for appropriate methodologies, rigueur within complexity and an evolution of approaches. Currently this evolutionary trend may be seen to culminate in a siding of IS research within critical frameworks. In this paper we will draw on a relationship between IS research and system analysis to use similarities and differences in an atte
Vehicle-to-vehicle (VTV) communications are of interest for applications within traffic safety and congestion avoidance, but the development of suitable communications systems requires accurate models for the VTV propagation channel. This paper presents a new wideband MIMO (multipleinput- multiple-output) channel model for VTV channels based on extensive MIMO channel measurements performed at 5.2
Thermo-mechanical fatigue crack propagation in Inconel 718 has been studied with different methods. In-situ observations with a scanning electron microscope (SEM) were performed, the crack propagation process was followed cycle by cycle and the influences from load, temperature, and microstructure on the crack growth were analyzed. To measure the displacements an image analysis technique was devel
Most embedded control systems have constrained computationalresources. This makes codesign of the control algorithms and thereal-time scheduling an interesting issue. There is also a strongtrend in the real-time community of moving away from the hardreal-time model. Hence, embedded controllers must be designed sothat they are aware of the resource constraints and timinguncertainty of the implement
Popular Abstract in Swedish Forskningsprojektet som rapporteras i denna avhandling har två övergripande mål. Det första målet är att utveckla testinstrument avsett för avancerade svenska inlärare av engelska, som genererar reliabla och valida testpoäng kopplat till receptiv kunskap avseende engelska kollokationer som en specifik förmåga. Med kollokationer avses konventionaliserade och frekvent förThe research reported in this thesis has two main aims. The first aim is to develop tests capable of yielding reliable and valid scores of receptive knowledge of English collocations as a single construct, for use with advanced L2 learners of English. Collocations are seen as conventionalized, recurring combinations of words, and the targeted types are adjective + NP and verb + NP. The second aim
Stream ciphers are cryptographic primitives that are used to ensure the privacy of a message that is sent over a digital communication channel. In this thesis we will present new cryptanalytic results for several stream ciphers. The thesis provides a general introduction to cryptology, explains the basic concepts, gives an overview of various cryptographic primitives and discusses a number of di
Boken behandlar de grundläggande delar av reglertekniken som används i processindustrin. Den är skriven på ett sådant sätt att den inte förutsätter några matematikkunskaper utöver grundskolenivå. Boken vänder sig framförallt till praktiskt verksamma operatörer, instrumenttekniker och instrument- och processingenjörer som vill fördjupa sina kunskaper i reglerteknik, men är även lämplig för teoreti
The paper describes a novel extraction procedure for lipopolysaccharides (LPS) from Salmonella enterica subsp. enterica (PCM 2266). Process parameters for the extraction of LPS from bacterial mass were optimized by carrying out a two-level fractional design experiment. Four parameters, namely temperature, CO, flow rate, pressure and co-solvent composition were analyzed. The best crude extract yiel
This dissertation seeks to describe, analyse and explain the contemporary poverty urban deprivation research and policies. By looking at the post-war planning policy of two specific urban neighbourhoods, the South Bank in London and the Leopold Quarter in Brussels, it seeks to demonstrate and clarify: 1) the growing political impotence of urban strategies, plans, policies and research projects tha
We establish a statistical model for the ultra-wide bandwidth (UWB) indoor channel based on an extensive measurement campaign in a typical modern office building with 2-ns delay resolution. The approach is based on the investigation of the statistical properties of the multipath profiles measured in different rooms over a finely spaced measurement grid. The analysis leads to the formulation of a s

Popular Abstract in Swedish Under en termin vid universitetet i Lausanne skrev jag det som kom att bli en forskarförberedande uppsats i religionsfilosofi om John Hick (f. 1922) och hans religiösa pluralism. Hicks religiösa pluralism handlar om att kristendomen inte kan eller bör betrakta sig som "den enda sanna religionen". Det blev allt klarare för mig under arbetets gång att frågor om religiös pHow to judge religions other than one's own when the means are lacking due to linguistic mobility? In the present thesis this question is mainly analysed in a Christian setting through a reading of the theologians Paul Knitter and Harold Netland. It is, however, claimed that the same question could be asked in other religious settings, also with regard to one's own tradition, and could be treated
