The wind effects on high rise buildings were studied by finding and reading books, articles and studying equations. This was done to calculate the first natural frequency of high rise buildings, wind induced acceleration on high rise buildings and how the comfort criteria of acceleration performing on high rise buildings acts on human bodies living in the building. The buildings that were studied

Composite steel and concrete structures can resist a fire, mostly because of the thermal properties of the concrete. This report examines a composite beam, HPC-beam, when the beam is exposed to standardized fire. The beam is designed after Eurocode and the Swedish national document. The material parameters are taken from the same sources. These material parameters are used as input data for applic

Syftet med rapporten är att kartlägga och analysera hur värdeflödet i samband med platsgjutning av en stomme fungerar idag, med avseende på bland annat arbetsfördelning, genomloppstider, resursanvändning, mellanlagring och informationsflöde. En utvärdering görs av hur metoderna Activity sampling och Värdeflödesanalys fungerar för kartläggning inom byggbranschen och hur resultaten från studier med

Tall buildings have lately become a problem to design because of the development of light weighted steel frames and wind loads. An important task of a structure is the absorption of horizontal loads and the capacity to transfer the resulting moment down into the ground. It is the engineer’s task to make sure that the structure’s performance is sufficient when it comes to safety and serviceability.

Problems considering vibrations influence on comfort and health have been known for long and extensive efforts have been carried out to describe them. However, the appearance of these problems in the appliance of concrete slabs is a new phenomenon which started to arise due to the development of prestressing. For this thesis some of the existing knowledge has been applied to determine the maximal

This Master Thesis has been written in coliabaration with Modulenthus and Lund Institute of Teclnology. This thesis has two pm-poses: To show how a VR-mode! best can be created by evaluating different programs and to examine the compatibility between ADT and Archicad.

Dagens byggande av bostäder präglas av ökade krav på kortare byggtider, lägre byggkostnader och en jämn och hög kvalitet. Miljötänkande har också fått en allt högre prioritet. De ökade kraven har medfört olika typer av satsningar på att förbättra material, teknik och metoder för att bygga villor. En tydlig linje i denna utveckling har varit en ökad användning av förtillverkade komponenter och elem

The Glass Ceiling is a proven and documented phenomenon for several countries. This paper tries to trace its existence of changing behaviour in the gender pay gap across the income distribution between the periods 1970 and 1990, and through a selection of professions for the highly educated individuals. This will show at the same time the transformation suffered by Swedish labor market between tho

Trenden för miniatyrisering av mikroelektronik närmar sig gränsen för vad som är möjligt att uppnå med konventionell kiselteknologi. En teknik, med potential att pressa utveckling mot allt mindre komponenter, är nanotrådstransistorer. I detta examensarbete studeras implementering av dessa transistorer i digitala kretsar. En fullständig analys av en krets innebär flera påföljande steg, innefattandThe continuing trend of electronic miniaturization is approaching a critical limit for conventional silicon based technology. Transistors based on nanowires are an interesting concept that might extend this trend deeper into the nano-scale domain. In this work, the usage of nanowire-based transistors is studied in the context of digital circuit design. The authors propose a complete workflow from

MikroRNA-96 och sin roll i prostatacancer För att en cell ska vara hälsosam och kunna uppfylla sina funktioner så måste cellen producera den rätta mängden och rätta sorten RNA-molekyler och proteiner som är kodade i cellens DNA. På grund av detta så är genuttrycket strikt reglerat i varje cell. När det gäller cancerceller är balansen störd vilket innebär att cellen delar sig okontrollerat och bil

Construction of wind turbines has increased these recent years and is expected to escalate more in the nearest future. The expansion of wind power as an energy source requires specific and comprehensive transport, when production is far away from the installation site. Generally, the development of turbines has gone towards bigger turbines with longer rotor blades. As the blades grow in length, op

With the growing pool of deposited protein structures, the need for structural analysis tools grows. In study of amino acid substitutions the variety of analysis tools is high; nevertheless, there is a lack of programs serving specific purpose, such as identifying if an amino acid substitution would cause a clash in the structure or not, given just the structure of the original protein. In this stAnalysing structural damage caused by changes in proteins In an organism, even only one single change of an amino acid can sometimes lead to disease, if the protein is a part of an important biological function. Because of that, it is important to study those changes and be able to predict if an amino acid substitution would cause harm. There are various ways a substitution can be harmful to a pr

The decline suffered by grassland pollinators in the south of Sweden may have great consequences resulting in the loss of important ecosystem services. However, cities may mitigate this effect as parks and other urban green areas can act as refuges for high pollinator diversity. Here I try to assess the status of the butterfly populations in the city of Malmö using as a reference a study carried o

Kriminalvården är värld som många har åsikter om, men samtidigt har få kännedom om vad som verkligen sker däri. Makt förekommer i olika former och därmed är det viktigt att beskriva ur ett inifrånperspektiv hur maktspelet på en anstalt kan se ut. Syftet med den här studien är att undersöka om synen på institutionell maktutövning skiljer sig åt mellan gamla och nya kriminalvårdare. Jag har med hjä
