Regression testing is expensive and may consume much of organizations’ software development budgets. Thus, it is of interest to reduce the total time devoted to test execution by using test selection techniques. Many techniques have been proposed but few have been evaluated on real-world, large scale systems. In this paper we report on an empirical evaluation of using the class firewall regression

Mary Flannery O’Connor (1925-64) was born in Savannah, Georgia as the only child of the American Irish Catholics Edward Francis O’Connor, Jr. and Regina Cline O’Connor. In 1952 her first novel Wise Blood, in 1955 the short story collection A Good Man Is Hard to Find, and in 1960 her second novel, The Violent Bear It Away were published. She received several fellowships and titles of Honorary Docto

Popular Abstract in Swedish Biotekniska läkemedel blir allt vanligare och behandlar några av våra viktigaste sjukdomar. Några exempel är insulin för diabetes, tillväxthormon, vacciner, och antikroppar som används i behandling av bland annat cancer, rheumatism och mag- tarmsjukdomar. Dessa läkemedel är proteiner eller peptider som tillverkas i jäst eller djurceller och sedan måste utvinnas ur celleTo design efficient and safe biopharmaceutical production processes, understanding the process and how it is affected by changes in the process conditions is essential. Experimental data form the basis of this understanding which can be enhanced by modeling and simulations of the physical and chemical processes known to control the process. This thesis describes modeling of preparative chromatogra

Polyphosphoinositides, the different phosphorylated variants of the phospholipid phosphatidylinositol (PtdIns), are used in a wide array of intracellular mechanisms in eukaryotic cells. The phosphorylation of PtdIns at carbon D4, catalyzed by phosphatidylinositol 4-kinase, is an important step in the synthesis of several of these molecules. The presence of different isoenzymes of PtdIns 4-kinase i

This essay reflects on issues of contemporaneity and on the possibilities and limitations to pass judgment on the time you live in. The essay won first prize in HSFR's essay contest for young Ph.D. students in 1998.

Popular Abstract in Swedish I denna avhandling analyseras olika typer av stabilitets fenomen. Först studeras det kvasi-statiska uppförandet av en elastisk struktur som lastas med en växande last. Beteenden vid laster som är högre än bucklingslasten studeras med en vägföljande metod där gränspunkter (limit-points) och bifurkationspunkter kan bestämmas med god noggrannhet och jämviktslösningarna kanIn this thesis different kinds of stability phenomena are analysed. Firstly the quasi-static behaviour of an elastic structure is studied for increasing loading. The post-buckling behaviour is studied numerically with a path-following method where limit points and bifurcation points can be determined with good accuracy and the solutions may be followed out on the secondary branches. Secondly, an a
