Analys av turbulensmodeller för CFD

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

I tider när det inte är strider

This master's thesis analyses the concept of equality between men and women in parts ofRegion Västra Götaland's area of operation. With critical policy analysis I analyse how theproblem of inequality is represented in the European charter for equality of women and men inlocal life (CEMR) and the Region Västra Götaland's plan of action for the charter. Throughinterviews with people responsible for gender equality in different areas I analyse, withdiscourse theory, the ways in which the concept of gender equality is articulated in differentareas of Region Västra Götaland, and what kind of politics these articulations enables.In the analysis I show that a discursive struggle of how equality is to be defined canbetter be understood as a discursive negotiation. Equality between men and women isunderstood in several ways at the same time, as antidiscrimination and basic human rights, asbalance between the sexes, and as an approach critical of norms and stereotypes. Within thesenegotiations certain understandings of gender are made possible or impossible.

Innovativt Drivpaket för Rullstol

This is a thesis for a Bachelor Degree Project, performed in the subject MechanicalEngineering. The students Roger Malmberg and Simon Hagberg have carried out adesign project on behalf of the recently established company J&D Assisting systems,located in Halmstad.The project consisted in developing J&D's first prototype of a power assisting solutionfor wheelchairs. A power assisted wheelchair combines human power, which is deliveredby the arms through the pushrims, with electrical motors, which are powered by a battery.The power assisted wheelchair is aimed at customers, who have used a regularwheelchair for a long time, but who have become weaker or just need additional powerwhen driving uphill. This kind of wheelchair will provide additional power for users,which will spare their wrists, elbow and shoulders. The product is torque sensor free andinstead it relies on the velocity.

Spelrörelsekrav och temporalt mönster i amerikansk fotboll : en deskriptiv studie av försvarsspelare

AimThe aim of the study was to develop a method for the survey of play movement demands and temporal patterns in order to enable a descriptive study of the defensive players in American Football. The overall aim was to  improve the understanding of how American Football is played to create opportunities for enhancement of current or developing new training methods to better suit football.MethodFifty plays from a Division 3 college football game on video from 2005 was divided into sequences of action for one player each from the defensive line, linebackers and defensive backs and analyzed with the video analyzing software cSwing. Every players sequence of action was recorded in a spreadsheet and noted on a scaled football field where distances were measured and together with time stamps from cSwing velocity was calculated.ResultsUsing this method it was possible to describe the play movement demands and temporal patterns which was the main task of the study. The defensive end worked on an average 4.61 seconds per play, the distance was 12.4 meters and average speed 2.5 m×s-1. The linebacker worked on an average 4.35 s per play, 13.7 m and at a mean speed of 3.0 m×s-1.

Avvikelser i energiprestanda

Calculated and measured energy in residential buildings is going to differ. The reason to this may be due to many factors. In this study there is a study on how these factors affect the energy use in a building. To get an insight in what defines energy, there is first a description of energy supply both worldwide and used in Sweden, followed by a description of the energy balance. In this study energy will be studied in residential buildings only.

Översvämningskartering av Vombs ängar

Vomb meadows is an area well knows for its rich bird life. During the 19:thcentury until mid 20:th century, the meadows were flooded annually in order toincrease the hay yield. The river Klingavälsån situated along the west side of themeadows, used to be a shallow river, meandering across the landscape. In the1940?s the river was straightened and made deeper.

EU:s jämställdhetspolitik ? ett janusansikte? En studie av EU:s jämställdhetspolitik med mammaledighetsdirektivet som belysande exempel

This bachelor thesis explores the conditions for a harmonized EU gender equality policy. Recently the maternity leave directive has been introduced by the European commission and seeks to improve the conditions for pregnant workers. The controversial subject of this maternity leave has illustrated many of the problems connected to the development of a social dimension in EU. First of all, the debate concerning the maternity leave directive in the European Parliament has shown that both sides in the parliament seem positive towards creating legislation in this matter on EU level. However, parties at the right tend to disagree to many of the amendments in the proposal, such as the maximum entitlement.

Patientupplevd vårdkvalité utifrån olika bakgrunder

I uppsatsen har jag undersökt om och hur mycket olika bakgrundsfaktorer hos patienter påverkar hur nöjda de är med vårdkvalitén. Uppsatsen begränsar sig till läkarbesök inom den offentliga Primärvården (Närhälsan) i VGR. Vi har använt oss av två olika metoder för att analysera data från Nationell Patientenkät från hösten 2011. Dessa är Binär logistisk regression och LASSO logistisk regression. Vi har valt logistisk regression därför att den beroende variabeln inte har intervallskala.

Kombinationsbruk, talltimmer och vilt?

When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.

Magasin för lagring av vatten och växtnäring

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

Varför varierar förvaltningsrevisionens omfattning?

Förvaltningsrevisionen är en mycket viktig del av revisionen, men förbisedd i forskningen. Vi vill med vår kandidatuppsats uppmärksamma förvaltningsrevisionen och vilka förhållanden i företaget som kan påverka förvaltningsrevisionens omfattning. De riktlinjer som gäller idag är utarbetade av FAR:s revisionskommitté och anger att förvaltningsrevisionens omfattning varierar från företag till företag som en följd av skillnader i förutsättningar och revisorns ambitioner och kompetens. Syftet med uppsatsen är att förklara vilka faktorer i företaget som påverkar förvaltningsrevisionens omfattning. Med hjälp av en egen teori vill vi förklara vilka faktorer i företaget som påverkar förvaltningsrevisionens omfattning, hur de påverkar och varför de påverkar.

Dräktighetsdiabetes hos hund :

This article presents a retrospective case study combined with a review of the current literature concerning canine gestational diabetes. A total of 14 cases have been collected from six different clinics in Sweden. There are few previously published reports on canine gestational diabetes. Gestational diabetes is a disease that rarely occurs in pregnant bitches. The condition is due to the rise of progesterone that occurs during the estrus cycle.

Elanslutning av fartyg i hamn : en studie om förutsättningar och konsekvenser för Köpings och Västerås hamn

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.
