Deltid och kön: En undersökning av deltidsarbetets utveckling under åren 1987-2005
This paper aims at assessing the relationship between female and male part-time employment and the business cycle in Sweden during the years 1987?2005 using quarterly time-series data and two alternative indicators of the business cycle. It further aims at determining whether the share of women working part-time has changed over time. Key results include that the relationship between the business cycle and female part-time employment is found to be significant and countercyclical. No significant effect is however found for men.
Energieffektiv torkning av kläder : en studie av torktumlare med varm- respektive kallvattenanslutning
Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of electrical energy. In the USA 9 % of the households electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential electricity consumption in Sweden is used drying and washing clothes.
Cykeltidsoptimering av sjuaxligt robotsystem
This master thesis studies how much the cycle time, i.e. the time it takes for an industrial robot to perform a given task, can be reduced if an extra degree of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an optimal way. The problem has been studied using simulations in the robot simulation tool RobotStudio. To be able to run an optimization in Matlab, with the RobotStudio simulation cycle time as the object function, communication between Matlab and RobotStudio has been set up with an interface written in Visual Basic.
Dimensionering av bärverk av stål : En jämförelse mellan Eurokod och BKR
The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

Problemet definieras genom frågan: Hur kan Uppsala universitet effektivisera implementeringen av administrativa stödprojekt? Syftet med denna studie är att lyfta fram kritiska framgångsfaktorer vid genomförandet av projekt. Färdigimplementerade administrativa stödprojekt studerades genom personliga intervjuer med projektansvariga och administratörer på institutioner. Upptäckterna analyserades med hjälp av en processorienterad teori baserad på Demingcykeln.
Från Bomull till Byxor Livscykel Inventering och Ansvarsfullt Företagande En MFS i Södra Indien
A growing number of companies realise that to achieve their environmental goals and satisfy stakeholder expectations, they need to look beyond their own facilities and to involve their suppliers in environmental initiatives. A life cycle approach means that the production system should be optimised as whole, across national boarders and individual organisations taking part all the way from extraction to disposal. This study is a Life Cycle Inventory of resources used when producing a piece of cotton garment and the method is based on the standardisation series of ISO 14040-43. The area of study, Tamil Nadu the most southern state of India, accounts for more than 90% of India?s knitwear exports to Western Europe.
Allmänhetens inställning och riskperception gentemot stålverk : En enkätstudie
Stålindustrin förser såväl människor som samhället med många nödvändiga byggstenar. I Sverige finns tolv ståltillverkande anläggningar och hela 80 % av stålet exporteras. Som alla andra tillverkande industrier har den flera miljöaspekter att ta hänsyn till, men stålets nytta väger tungt och därför är det av stor vikt att genom forskningsprojektet Stålkretsloppet nå hållbar utveckling. Miljöskyddslagen, miljöbalken och ett ökande miljöengagemang har lett till arbete med miljöfrågor. Syftet med den här studien var att undersöka hur allmänhetens riskperception, attityd och oro gentemot stålindustrin ser ut.
Barns tolkning av en modell för vattnets kretslopp : -förståelse och tillämpning
AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.
Optimering av fackverksmodellering : Ett makro för Tekla Structures
This project is the result of a cooperation between HalmstadUniversity and EABAB. The aim of the project was to create a macro that would help EABAB automate the process of designing steel trusses. When run in Microsoft Excel, the macro imports and processes coordinates from a calculator program. The data is then imported into the Building Information Modelling software Tekla Structures, which creates a 3D structural model of the steel truss.The macro saves much time in the project planning process and also helps minimize the risk of design flaws caused by human error. .
Optimering av glödgningsparametrar för kromstål
At Sandvik Materials Technology, Argon gas is used as furnace atmosphere when heattreating hot rolled wire. Upon heating chromium steel wire, a rich oxidelayer forms on the wire surface. The abstract of this masters thesis is to enhance the understanding of the constitution of the oxidelayers and the influence of the furnace atmosphere. This will be achieved by performing a number of annealing experiments on laboratory level. Also, the aim is to understand the chemical reactions and physical mecanisms controlling the pickling process.
Omloppstid för returenheter
Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.
SAMVERKAN STÅL/BETONG : Kontroll av kapacitet hos blockankare i Connector Samverkansbalk
In April 2007 we contacted Lennart Augustsson at Designpartners AB in Västerås. He came up with the idea to investigate and evaluate their construction of a interaction beam, CSB-beam. CSB is short for Connector Interaction beam. The beam is based on a horizontal C-profile of high-tensile steel and in the bottom of the profile are vertical flat bar welded so called block connectors. These block anchorsare also made of hightensilesteel.

Att ta cykeln till arbetet : en studie av Stockholms satsning på cykelpendlare i jämförelse med Köpenhamn och London
The bicycle is an individual means of transport. Many people prefer to cycle over short distances and in congested areas rather than take travel by car or public transport. This is a study of the use of bicycle as an option for commuting to work. It is a comparison between three cities: Stockholm, Copenhagen and London. The comparison is focused on solutions that benefit commuter cyclist and performed by studying cycle policies and other related documents.
The control of the cell cycle with particular emphasis on the G1/S transition
Tumour development occurs to a large extent because of dysregulation of the cell cycle. Of particular importance are defects occurring in the G1 phase. The reason why G1 is critical is because of the influence of several signals (external signals as well as cyclins and cdks) on this stage. The G1 phase can be divided into two parts, G1pm and G1ps. Each part has its ?own? restriction point which needs to be passed in order to progress to S phase.
