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

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

När vi jämför människan med andra djur, letar vi gärna efter särdrag som gör henne unik. Hur Homo blev sapiens lyfter fram människans alldeles speciella förmåga att tänka och att skaffa sig kunskap om världen. Under människans långa utveckling blir tänkandet gradvis alltmer avancerat. Gärdenfors vägleder oss genom hjärnans och tankeförmågornas vindlande tillblivelse, och visar hur människans inre

Innovations should create value for increasingly individualistic consumers with varying demands and for other stakeholders. Today, retailers have the power in the supply/value chain. This research investigates how Swedish food retailers view innovations, their role and that of customers and suppliers in the development process, and how they see future development. The study is based on open-ended

Abstract in UndeterminedWarfare and legitimate violence have long been seen as key elements in state formation. Persistent Piracy brings into the picture the long missing component of maritime violence – and shows it to be of vital importance to the formation and, on occasion, disintegration, of states. Spanning from the Caribbean to East Asia and covering almost 3,000 years of history, from Class

Popular Abstract in Swedish Småbarnsskolan. Vad hände och varför? En sekellång historia studerad med fokus på förändring av pedagogisk verksamhet från 1833 och framåt. I denna bok tecknas en bild av småbarnsskolan som pedagogisk företeelse i Sverige. Den första småbarnsskolan inrättades 1833 och i kölvattnet följde ett trettiotal. Flera småbarnsskolor överlevde sekelskiftet och behöll sina beteckSome fields in the research about the history of childcare in the nineteenth century in Sweden is lacking. In popular textbooks infant schools (småbarnsskolor) are thought of and described as a pedagogical and social activity, while a later phenomenon, the nursery schools, seemed to lack all pedagogical insight, care-taking was exclusively at hand. I have questioned this dichotomy. What happened t

Popular Abstract in Swedish Det här arbetet handlar om individuell religiositet, snarare än om religion. Min studie rör i första hand människor som utövar zen, och har mindre att göra med zenbuddhism som ideologiskt system. Jag försöker utforska det stora gapet mellan teori och praktik. De mer abstrakta doktrinerna och idealiserande normerna har haft en benägenhet att dominera arbeten om zen, såväThis work is not so much about religion as about individual religiosity. It is primarily about people practicing Zen, less about Zen Buddhism as a systematic ideology or philosophy. I set out from the start to try to explore the wide gap between theory and practice in Zen. The more abstract doctrines and idealized norms have had a tendency to dominate works on Zen, confessional as well as scholast

Traditional methods for evaluating corporate credit risk rarely consider the impact of the macro economy on corporate value and performance. We argue that lenders and management can obtain valuable information about the need for and approach to restructuring by decomposing default predictions into intrinsic and macroeconomic factors. We apply a method previously used for measuring macroeconomic ex

Blekinge är ett landskap som trots sin litenhet hyser en variationsrik natur. Skärgården blandas av små, kala skär och större trädbevuxna öar. Kusttrakternas mosaik av lummiga lövskogar, samt öppna ängs- och åkermarker, övergår norrut i barrskogar och slingrande åar eller små sjöar. Floran presenterar alla Blekinges arter med beskrivning av deras utbredning, miljö, samt förändringar i frekvens. Et
