Konstruktion av säkerhetslagerför svänghjul
This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.
Hur kan vi lyssna på de tysta?
The knowledge that citizens have of their own municipality is very useful for the local politicians and planners in the event of such a major reconstruction in the neighborhood. It is the residents in the area that are most affected, and their view on the reconstruction is valuable if the end result will be as good as possible. Since the municipality builds for the citizens, and wants them to enjoy the outcome of the reconstruction as much as possible, it is essential that the municipality get a chance to inspect the citizen?s views and experiences about it in an early stage. If the citizens don?t want to get involved, or if only a few people involve themselves, it will be difficult for the municipality to find a solution satisfactory to all.
Bolagsskattens påverkan på marknadsvärdet : En eventstudie kopplad till kapitalstruktur
Sverige genomförde vid årsskiftet 2012/2013 ytterligare en sänkning av bolagsskatten. Denna gång från 26,3 till 22 procent. Målet med sänkningen var att hamna under EU?s genomsnittliga bolagsskattenivå vilket skulle minska företags incitament till att fly Sverige för lågskatteländer. Samtidigt ville regeringen minska företagens skuldsättningsgrad.I teorin sjunker värdet på skatteskölden vid en bolagsskattesänkning och därmed också värdet på företagen.

Terrorism - ett hot mot ekonomin? : En eventstudie om hur terroristattacker påverkar den svenska aktiemarknaden
Syfte: Huvudsyftet med studien är att undersöka om avkastningen på den svenska aktiemarknaden påverkas av terroristattacker. Delsyftet är att vid en eventuell påverkan undersöka om reaktionen skiljer sig mot landet där attacken skett samt hur lång tid det tar för de olika aktiemarknaderna att återhämta sig.Teoretiskt perspektiv: Den teoretiska referensramen utgörs av teorin om den effektiva marknadshypotesen samt behavioral finance med fokus på flockbeteende.Avgränsningar: I studien undersöks åtta olika terroristattacker och dess påverkan på aktiemarknaden i Sverige och landet där attacken skett.Metod: Studien är kvantitativ och använder ett deduktivt angreppssätt. För att besvara frågeställningarna tillämpas en eventstudie där två eventfönster används. Ett eventfönster på en dag och ett längre på elva dagar samt en estimeringsperiod som omfattar 30 dagar. Insamlad data används för att mäta den avvikande avkastningen som eventuellt uppstår efter att en terroristattack ägt rum vilket säger om attacken haft någon påverkan.Slutsatser: Terroristattacker har en påverkan på den svenska aktiemarknaden och i de flesta fall är påverkan negativ.
Akustiskt åtgärdsprojekt av en rockmusikklubb där live-musik spelas. Vad kan en audionom bidra med?
Introduction: The number of hearing impairments in Sweden is increasing. The largest increase is seen in ages 25-44. There are reasons to believe that these impairments are noise induced. Leisure time noise is not controlled in the same manner that industrial noise is. An ongoing conflict between city council officials and rock club owners, musicians and music event organizers about sound levels at smaller live music clubs exceeding the national sound level restrictions created the need for an acoustic intervention project.
Stockholms blodbad i historieboken: En l?romedelsanalys under perioden 1869 - 1996
This thesis explores in which ways the portrayal of the event known as the Stockholm bloodbath has changed during the period 1869-1996. This is done through textbook analysis. In Sweden, history has been a school subject since the 17th century, and has throughout its history had a formative role in the Swedish school system. In the middle of the 19th century it was specifically stated that the aim was to help students nurture a sense of national pride and love of country. The aim of the study is to investigate how nationally loaded events have been portrayed in text books, as well as if and how the evolution of said textbooks reflect the evolution of the history subject as a whole.

A third aim is to investigate how uncertainties in input variables to smoke spread calculations will affect the result of calculation. To be able to do this the most important input variables are identified and analysed.
Hur kan studie- och yrkesvägledaruppdraget förstås?
The main purpose with this study was to investigate how study- and careers counselors active in primary school, secondary upper high as well as colleges describe regarding satisfaction of assignments and suggestions on their development. The study also included in what extent pure guidance tasks cover these assignments as well as what criteria affects these.Six study and careers counselors were interviewed during this study, all active in the three separate educational programs. Their responses regarding what tasks are included in their assignments as well as experiences are in line with previous research. The conclusion drawn from this study shows deviational results in-between the three educational programs, this regarding guidance tasks in their assignments. The conclusion strongly pinpoints that criteria as ?time? and ?need of guidance? affect to what extent guidance tasks fills these study and career counselors assignments..
Vallfoder till slaktgrisar : effekter på tillväxt och social beteende vid utfodring
The aims with the project were to investigate how forage consumption affect production and pigs behaviour around the feeding. This degree project was designed to follow 48 growing/finishing Hampshire*Yorkshire pigs, from 30-110 kg live weight, fed diets with or without 20 % forage inclusion. The pigs were divided in three groups due to dietary treatment. In the first group the pigs were fed 20 % of the energy in the feed ration by long grass/clover silage (LE) and the remaining 80 % by a cereal concentrate. Group two was fed chopped grass/clover silage mixed with cereal concentrate (HE) in the same amounts as LE.
Fjärrstyrning av videokamera
On some occasions it may be inappropriate with a cameraman behind the camera. In somecases there is no cameraman available or it is a smaller event, like a family celebration, to befilmed. It can also be difficult for a cameraman to shoot from certain angles. One solution forthis kind of situations can be to remotely control the camera movements. There are thosekinds of solutions on the market today but they either address professional filmmakers or thefunctionality is limited, for example by the absence of wireless remote control.This project aims to develop a solution to the problem with absence of wireless remote controland also a solution with more flexibility and less complexity than today?s solutions.
Effekter av visuell feedback på slutanvändaren inom design av gränssnitt för webben
Redan 1899 skrev Woodworth om iakttagelser av effekten av visuell feedback på rörelser. Sedan dess har ett stort antal studier berört ämnet och studerat effekterna de medför. Denna studie anser att det finns brister i kunskapen om visuell feedbacks effekter inom vardaglig användning. Genom att låta deltagare använda och utvärdera instanser av en bokningsplattform för biljetter till ett event har studien observerat användarens upplevelse och effektivitet under processen.Den insamlade datan analyserades via variansanalys men lyckas inte avfärda nollhypotesen. Studiens resultat visade ingen korrelation mellan närvaron av visuell feedback på hover-funktionen och användarens effektivitet och upplevelse.

Retentionsr?tt och Legal Pantr?tt: Tv? Rigida Begrepp i ett Flexibelt R?ttssystem? En studie om hur retentionsr?tt och legal pantr?tt kan hanteras med hj?lp av ett funktionalistiskt angreppss?tt
Possessory liens and legal liens are two securities that has been the subject of debate from legal scholars for quite some time. Possessory liens are often viewed as a weaker security compared to legal liens. However, upon closer examination it turns out that possessory liens in most cases provide the the same opportunity to sell the property withheld as security. This possibility makes possessory liens resemble, if not be identical to, legal liens. Both securities arise by operation of law and grant the right to both withhold and sell property in the event of non-payment.
