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

The article is a description and evaluation of extensive and intensive field survey as a means of locating sites from the bronze and early iron ages in the cultivated landscape of southern Sweden. It includes a discussion of other field survey efforts and recommendations about survey technique. Surface survey in December proved to be a fairly successful means of locating bronze age remains in clay

The paper presents the emerging field of integrated control and CPU-time scheduling, where more general scheduling models and methods that better suit the needs of control systems are developed. This creates possibilities for dynamic and flexible integrated control and scheduling frameworks, where the control design methodology takes the availability of computing resources into account during desi

En kritisk essä om pedagogik inom civilingenjörsutbildningarna i Sverige. Den tar sin utgångspunkt i antagandet att det kanske inte är teknikintresset som är den springande punkten, utan att det helt enkelt är tråkigt att studera vid de tekniska högskolorna, i synnerhet under de första åren.
