Att bygga betongbroar med inslag av prefabricering i Sverige är idag relativt ovanligt. Man vill gärna undvika obeprövade metoder för att hålla riskerna i projekten så låga som möjligt. Samtidigt har det prefabricerade byggandets potential att öka effektiviteten och därav också lönsamheten lett till att en del prefabricerade broar byggts. På senare tid har Trafikverket, den enskilt största bes

Initially, this paper presents an overview of the existing methods used for the identification of vortices in fluids, attempting to point out their different strengths and weaknesses. In addition, a new method is proposed to identify vortices directly from velocity field information. It defines a point inside a vortex as a point around which there is rotation. By looking at the velocity directions

The aim of this study is to investigate whether a virtual environment can be used as a complement to conventional experiments regarding human behaviour in fires and evacuations. Initially, a study of previous research in the field of human behaviour in fires and Virtual Reality was performed. To be able to do a validation of the use of Virtual Reality in relation to conventional experiments, a pre

The purpose of this thesis is to test if the depth of business cycles, i.e. if the acquisition is performed early or late within a cycle, affects performance. The intention is to contribute to M&A research by using stock market data and accounting data from selected companies to bring further light on postperformance research by adding the variable of business cycles. The authors also wish

I Sverige har antalet patienter som vårdas hemmet ökat de senaste åren och flertalet människor önskar dö i sitt eget hem. Palliativ vård är en aktiv helhetsvård av patienter i ett skede när sjukdomen inte längre går att bota och det övergripande målet med palliativ vård är att uppnå bästa möjliga livskvalitet för patienten och dennes anhörig. Distriktssköterskan eller sjuksköterskan betraktas vara

The right to equal treatment, employment on equal terms and labor market integration regarding disabled individuals has been a topic for discussion on both international and EU legal in recent years. In spite hereof, the Swedish Labour Court´s recent decision in case AD 2012 No. 51 shows that the Swedish judicial system allows for people with a reduced working capacity to be at a disadvantage in r

Child sexual abuse (CSA) is a significant public health problem with serious consequences for human and socioeconomic development. In Nicaragua there is a dearth of information about CSA in relation to the health sector. The purpose of this study was to assess the Nicaraguan health sector’s most fundamental capacity to respond to CSA, by way of investigating the conceptions constituted amongst hea

Det är numera allmänt vedertaget att 80% av materian i universum består av en ny sorts partiklar som inte strålar eller interagerar med ljus. Med andra ord, den är ”mörk”. Vi känner redan till en slags ”mörk” partikel - neutrinon. Alla partiklar som är elektriskt oladdade är ”mörka”, men mörk materia kan inte huvudsakligen bestå av neutriner. Mörk materia verkar bestå av partiklar som är myckeWIMPs, orWeakly InteractingMassive Particles, are a popular dark matter candidate, but their detection remains elusive. At its core, this project is an effort to bridge the gap between the theory of WIMPs, and astronomical observation. According to the WIMP model, stars in the galaxy travel through a background field of WIMPs that are constantly crossing the star. Some of these WIMPs collide with

The MS thesis is concerned with the problem of scheduling the daily energy loads in a multihouse environment from the point of view of an energy retailer. We assume that the residential users own a set of home appliances (washing machines, dishwashers, ovens, microwave ovens, vacuum cleaners, boilers, fridges, water purifiers, irons, TVs, personal computers and lights) that are supposed to be use

The social network analysis is a method on studying social relations which is becoming more and more popular on the arena of social science. This thesis examines, in the perspective of sociology of law, how well the above mentioned method can be used on studying criminal networks which are specialized on narcotic crimes. The basic idea for this thesis is that criminal networks are often based on t

This thesis aims to explore Wizard of Oz testing in conjunction with Augmented Reality (AR) and focus has been put on testing AR with Head Mounted Displays. The recent increase of interest in HMDs with products such as MOD Live from Recon Instruments and Google's Project Glass puts new demands and possibilities on human-computer interaction. Since the commercial market for HMDs is still in its

I uppsatsen analyseras barns svarsmönster på semantiska ordflödesuppgifter. Uppgiftstypen går ut på att producera så många ord som möjligt inom en given kategori under en minut. Analyserna bygger på data från 63 barn med typisk språkutveckling. 32 av barnen gick i förskoleklass och 31 av barnen gick i årskurs två vid tiden för datainsamlingen. I den första frågeställningen analyseras svarsorden ut

Naturliga grusavsättningar är ändliga resurser och verkar som akviferer för grundvatten vilket gör dem viktiga för det svenska samhället. För att kunna bevara dessa värdefulla tillgångar måste ett ersättningsmaterial hittas; krossten (aggregat) är ett bra alternativ. I föreliggande undersökningar har tolv bergartsprov av gnejs från det Östra Segmen-tet i sydvästra Sverige analyserats för att se huNatural gravel deposits act as aquifers storing ground water but are a finite resource and an important asset to the Swedish community. In order to preserve these assets for the future substitute materials have to be located; crushed rock material (aggregates) is an alternative. Twelve gneiss samples from the Eastern Segment, southwestern Swe-den, have been characterized and analyzed for suitabili

Scientific abstract Soil moisture (rainwater accumulated over a period of time in soil) is considered one of the most important factors on vegetation growth in Sahel as the agriculture droughts usually associated with soil moisture deficiency. This thesis study investigates the correlation relationship between soil moisture and vegetation greenness in the Sahel region from 1982 to 2008 at differen

Syftet med studien är att öka kunskapen om hur styrmedel påverkar energieffektiviseringen av det befintliga beståndet. Studien skall undersöka vilka styrmedel för energieffektivisering av befintlig bebyggelse som finns idag och hur väl dessa fungerar. Studien skall även undersöka vilka incitament som finns för energieffektivisering och vilka faktorer som upplevs som hinder mot energieffektiv

In May 2009, a new Swedish legislation made it possible for a new tenure to enter the housing market – condominiums. Since the law took effect, only a few condominiums have been built, mainly by minor construction- and property companies. This thesis aims to investigate under what circums- tances it’s favorably to build condominiums and also to identify what ob- stacles and opportunities that c
