Abstract— Context: Software product lines (SPL) are used in industry to achieve more efficient software development. To test a SPL is complex and costly and often becomes a bottleneck in the product line organization. Objective: This research aims to develop and evaluate strategies for improving system test selection in a SPL. Method: Initially industrial practices and research in both SPL testing

The knife-edge technique for measurements of micrometer-sized beams is extended to two-dimensional imaging by tomographic reconstruction of multiangular knife-edge data. Two-dimensional intensity distributions at optical (633-nm) and soft-x-ray (13.5-nm) wavelengths at the focal region of a Schwarzschild objective are presented. The resolution is limited by the 200-nm step size used in the data ac

Inference to the best explanation (IBE) is theoretically interesting in that it promises to throw new light on what an explanation is. IBE challenges the standard view of the relation between inference and explanation. But sometimes it seems that previous explanation is more independent of inference than IBE suggests. Sometimes we have explanation before inference (EBI) which is not IBE. This chap

Popular Abstract in Swedish Enzymet magnesium-kelatas katalyserar bildandet av magnesium-protoporfyrin genom insättning av en magnesiumjon i protoporfyrin. Detta är det första unika steget i tillverkningen av klorofyll hos växter, alger och fotosyntetiska bakterier. Magnesium-kelatas består av tre proteiner som kallas I (vikt 40 kDa), D (70 kDa) och H (140 kDa). Det är viktigt att bestämma dessa pThe enzyme magnesium chelatase inserts magnesium into protoporphyrin IX (Proto) to produce to magnesium protoporphyrin IX, the first unique intermediate of the chlorophyll biosynthetic pathway. Magnesium chelatase is composed of three distinct proteins termed I (molecular weight ~40 kDa), D (~70 kDa) and H (~140 kDa). Defining the individual properties and structure of the magnesium chelatase comp

This thesis treats the acquisition of Italian (and Swedish) in two bilingal children ad a control group of six monolingal Italian cildren (for some domains studied). It is a longitudinal study of the spontaneaous speech of the children. In both children one language is weaker than the other in terms of MLU, amount of utterances and code-mixing while speeking with an interlocutor of the respective

Packaging Logistics is a concept that recognises the need for coordination of the packaging system and its manifold functions throughout a package’s life cycle. Packaging Logistics is an area in need for substantial theoretical building. This dissertation elaborates on its underpinnings and suggests conceptual models that should be useful in better understanding the core of the concept, its undere

This paper presents a study of disfluencies in written language production. Texts from ten university students are compared to data from people who almost never use writing, namely adult dyslexics and to texts from people who communicate in writing under real-time constraints every day, namely deaf whose main use of writing is text telephone conversations. This paper investigates which types of di

Various parameters in dynamic load models were determined from the normal operation data. Steady state load-voltage dependence, transient load-voltage dependence and a load recovery time constant parameters were chosen for the study. It was observed that large variability in voltage was due to high diversity of load processes. It was also observed that transient reactive load-voltage dependence wa

The dissertation delineates the development of silent film music in Sweden in relation to changes in the production practices. Also, the study shows, through analyses of certain Swedish films from 1919-1928, that music to narrative silent film had and still has a dramaturgical, structural, narrative and dramatical function which has to be taken into consideration when one studies the reception of
