The traditional sheet metal forming process, including cast steel die tool and conventional work materials, is fairly well established and analysed. Developments of new alternative materials make great demands upon new forming processes and manufacturing methods. A general goal for the manufacturing industries is to reduce the weight of metal parts, reduce batch sizes and reduce the lead-time of n

This dissertation, based on six included papers, theoretically investigates properties of quantum few-particle systems. An overview of related experimental research - ultra-cold trapped dilute gases, and electrons in quantum dots - is given, followed by a description of some of the studied many-particle phenomena - Bose-Einstein condensation, quantized vortices, Wigner localization and the Tonks-G

The friction stir welding procedure to seal copper canisters requires variable power input throughout the 45 minute long weld cycle to keep the welding temperature within the process window. This is due to variable thermal boundary conditions throughout the weld cycle which, together with fast disturbances in the spindle torque, requires control of both the power input and the welding temperature

The Swedish concept of folkbildning (the ‘bildung’ of the people) and its introduction in the mid-1900th century was connected to the advent of Folkhögskolan (the popular adult education) with explicit as well as implicit references to the Danish philosopher Gruntvig’s ideals of education. The broad popular movement which the adult education ideals was incorporated into during the beginning of the

Emotion and perception are expressed in every language, but their linguistic analysis is surprisingly sparse at typological level. In this paper, an initial attempt is made to describe typological characteristics of emotion and perception and form an initial classification.
Verbal constructions expressing emotion and perception normally have a slightly different argument structure in compariso

Tech-lex består av en ordlista med trafiktekniska begrepp (Traflex) som efter hand kompletterats med övriga tekniska facktermer relevanta för forskning och undervisning på V-huset, LTH. Ämnena är trafikteknik och trafikplanering inkl vägbyggnad, brandteknik, miljö, fysisk planering med fastighetsrätt samt bostadsfinansiering. Ordlistan Traflex är ursprungligen en databas som kompilerades för att

A description of the set up and the functioning of Swedish Equality bodies and an analysis of whether or not the setup complied to the demands of the three directives.

The Internet constitutes a heterogeneous mesh of networks with highly varying characteristics. One of the features of this environment is that there normally are a number of possible paths for data to travel between two end-hosts. These different paths exhibit highly different properties in terms of bandwidth, delay, reliability etc. One of the challenges in this environment is to map the properti

The implementation of the Biofuels Directive (2003/30/EC) in the 25 member states is assessed against the background of implementation theory in this paper. The aim is to identify and analyze implementation problems for the purpose of suggesting a way forward for biofuels policy in the European Union. Three main patterns of policy implementation are observed: effective implementation, formal compl
