Tolerances, including geometry, dimension, and surface roughness, are an important part of production where the desire to manufacture quality products have to be weighed against the increase of manufacturing costs. The desired tolerance will influence the choice of both manufacturing method and machine tool. Given that machining is an adequate production method, variation of the required tolerance

LTH:s SI-verksamhet på gymnasiet är ett samarbete mellan LTH och elva gymnasieskolor i närregionen som startade under hösten 2007 och går ut på att använda den s.k. SI-metodiken som komplement till den ordinarie undervisningen i naturvetenskapliga ämnen. SI-mötena leds av teknologer från LTH. Syftet med samarbetet är flera: att förbättra samverkan mellan LTH och gymnasieskolor i närregionen; öka i

Kampen för att resa monument och minnesmärken som en kamp om rummet i staden - om rätten till historien. Sverige och Ådalshändelserna 1931 som också blivit en del av berättelsen om det fredliga folkhemmet, samt USA och Haymarket 1886 som blivit en dela av traditionen om första majfirandet världen över.

Popular Abstract in Swedish Vår läkemedelsanvändning har eskalerat de senaste två årtionden och vi har kunnat behandla, bota och förebygga sjukdomar samt minskat antalet oönskade graviditeter i större utsträckning jämfört med förr. Detta har dock också fört med sig negativa effekter och miljöproblem efter att läkemedlen kommer ut i naturen. Ett antal läkemedel är så kallade endokrina störningssubsSynthetic hormones are a group of pharmaceuticals used for various human and animal treatments. However, consumption and disposal of these substances have also given rise to negative effects and environmental problems for organisms in the wild which is why these substances have been classified as estrogenic endocrine-disrupting chemicals (EDCs). Studies on the estrogen receptors (ers) and their ge

Popular Abstract in Swedish Denna avhandling presenterar nya metoder för att analysera bilder på hjärtat för att utesluta eller bekräfta kranskärlssjukdom. Hjärtat har en livsviktig uppgift, att pumpa runt blodet för att förse alla kroppens organ med energi och syre. Vid förträngningar i kärlen som försörjer hjärtmuskeln med blod (kranskärlen) uppkommer ett tillstånd som kallas ischemisk hjärtsjukIn this thesis, methods for automated analysis of myocardial perfusion single photon emission computer tomography (myocardial perfusion SPECT, MPS) images have been successfully developed and evaluated. MPS images show the perfusion of the myocardium and are used for diagnosing patients with suspected ischemic heart disease. The disease is characterized by reduced perfusion to a region of the myoc

In this thesis a simulation model is presented that enables a comparison of different hybrid topologies, with respect to fuel consumption, emissions and performance. The obtained results stress the properties of the different topologies and form a foundation for the choice of hybrid topology. The simulation models included in this thesis are the result of collaboration with Petter Strandh at the D

Dialogue or governance? The relationship between the state and the voluntary organizations, with particular focus on Överenskommelsen (the compact) and the Church of Sweden Government-voluntary sector compacts have emerged in the recent years, as a nonprofit policy practice in many industrialized countries. The compact – in Sweden signed by the government in 2008 – is by some researchers regarded

This volume is a collection of some of the most important philosophical papers by Peter Gärdenfors. Spanning a period of more than 20 years of his research, they cover a wide ground of topics, from early works on decision theory, belief revision and nonmonotonic logic to more recent work on conceptual spaces, inductive reasoning, semantics and the evolutions of thinking. Many of the papers have on

This memo reports on factors that drive and inhibit the digitalization of security systems. The reported factors are as follows: Technology-push factors • Need to lower costs on the end-user side, i.e. replacing labour with technology • Perceived convenience and ease-of-use of digital systems • Digital products can be connected to the current enterprise network; enabling an expanding set of secur
