The stainless steel metal includes a large group of alloys and which one should choose for a process can be difficult to determine. Despite much research on corrosion, there is still disagreement on the impact of the corrosion resistance from passivation. This master thesis was assembled together with Tetra Pak to see the influence of passivation on stainless steels used in their processes. The g
Det finns i dagsläget flertalet tekniska lösningar för att begränsa konsekvenser av bränder i bostäder. Exempel på sådana kan vara sprinkler och brandvarnare. Ytterligare möjligheter för att reducera konsekvenser av brand i bostäder finns, där planlösningar i bostäder borde kunna användas som ett komplement till övrigt brandskydd. Syftet med examensarbetet är därför att undersöka planlösningar i bThe aim of this thesis is to investigate the impact of floor plan parameters in a residential dwelling regarding the consequences of fire that may endanger human life and health.

The aim of this study is to investigate parameters that influence the effectiveness of the two main methods of smoke management, thermal and mechanical smoke ventilation, to determine when one of these methods is favorable to the other. To accomplish this simple hand calculations as well as more advanced computer programs, such as FDS and Argos, were used. The study was conducted in collaboration
This thesis is oriented around designing the world first inelastic hyperspectral LiDAR(Light Detection and Ranging) system for aquatic use. The system was designed around the task of monitoring zooplankton and environmental indicators in water. Scheimpflug lidar was previously developed for monitoring flying insects, aerosols and gases. Here we extend the concept to inelastic hyperspectral ranging ca
The purpose of the study was to investigate if dynamic way-guidance systems, namely flashing green lights mounted by an exit sign, can be used to increase the usage of lesser known egress routes in department stores. The study consisted of a literature study as well as experiments at Gekås department store in Ullared, Sweden. Two experiments were undertaken, one in the vicinity of the checkout and

With effect of global warming and climate change the electrification of vehicles enables a more sustainable and environmentally friendly alternative to conventional vehicles as it reduces toxic emissions and overall energy consumption. Different extents of electrification is today used. Hybrid and electric vehicles are two examples. Tools to simplify the design of electric vehicles are of value to
Problem: Hållbarhetsredovisning har alltid varit fri från formkrav vilket har inneburit stor flexibilitet för företag både sett till om hållbarhets- rapporter ska upprättas och vilket innehåll dessa ska ha. Då lagreglering blir gällande från och med räkenskapsåret 2017, som gör det tvingande för större företag att hållbarhetsredo- visa, frågar vi oss hur detta lagkrav kan komma att påverka den inf

This text aims at describing an archaeology of relations. Methodologically many approaches are being tested, through a multiple-angled discourse analysis. Relational archaeology studies the interactive middlegrounds in between two actors, or between smaller components that exist within one single actor. What is of relevance here is then how to define and outline the »actor«. This thesis demands th
