This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

Syftet med studien är att bidra till kunskap och förståelse kring fenomenet gamification. Denna kartläggning bidrar till att klargöra för- och nackdelar, möjligheter och risker samt eventuella fallgropar med gamification. Om en organisation är medveten om dessa aspekter kring fenomenet minskar riskerna för att någonting ska gå fel, vilket potentiellt skulle kunna bli kostsamt.Studien vilar på en teoretisk referensram hämtad från såväl managmenent- som psykologiforskningen. Förväntansteorin, self determination theory, flow, McGregors Teori X och Y, principal-agentteorin är några av de teorier som används för analysen av gamification.Då det handlar om en kartläggning kring ett relativt nytt fenomen behandlas flera exempel på gamification hämtade från företag som verkar inom branschen. En intervju med speldesignern Henrik Englund finns också med, samt en fallstudie kring polismyndighetens omskrivna användning av spelelement.

Uppsatsens huvudsakliga syfte är att utforska och kartlägga begreppet gamification. Syftet operationaliseras i tre frågeställningar. Vad finns det för likheter respektive skillnader i synen på Gamification mellan ett antal yrkesverksamma inom Gamification? Hur ser yrkesverksamma med olika bakgrunder inom psykologi, pedagogik och marknadsföring på framtiden för Gamification och dess användningsområde? Vilka för- och nackdelar kan finnas med Gamification? Uppsatsen teoretiska utgångspunkter omfattar de psykologiska krafterna bakom spel som flow och motivation, teorier om det praktiska användandet av gamification och teorier om Generation Y. För att samla empiri har kvalitativ metod använts i form av semistrukturerade explorativa intervjuer där yrkesverksamma inom gamification har intervjuats.

The aim of this thesis is to examine how personnel working with asylum cases at the Swedish Migration Board handle their role as administrators of asylum. For the study 7 asylum administrators were interviewed and the analysis was made with influence from the method critical discourse analysis. To understand the themes in the analysis I have used Michael Lipskys theory about street-level bureaucrats. Main results from the analysis of the interviews were that the street-level bureaucrats had certain strategies for managing the difficult aspects of the job. The interviews also showed that the participating informants had difficulties with different identity positions..

Miljonprogram is a Swedish building program from 1964 to 1975. During that time about a million homes were constructed. Now, almost 50 years later, they are in desperate need of renovation. In order to fulfil the Swedish environmental objective to decrease energy consumption 50 per cent until 2050, considerable housing stock built under the Miljonprogram has to be renovated.Focus in this thesis is on the building services and theirs profitability that can decrease energy consumption in households build during the Miljonprogram. Building construction is not considered in this report.

Ericsson AB in Katrineholm is a part of the Section Business Unit Network in the Ericsson Group. The plant's main task is to produce printed circuit boards in small volumes with a high product mix and focus on delivery and cost effectiveness. At the factory they produce printed circuit boards in the Module department.The Module department has for a long time had a high output of non-approved circuit boards in their production. This has led to a growing stock of non-approved circuit boards on the company?s repair department.The purpose of this thesis is to investigate how Ericsson in Katrineholm can increase the outflow of approved articles in their test process in the Module department.

This is a report written for an examination project C-level, on the subject of energy. The examination project is a product of the FVB Sweden AB (district heating bureau). It started with a meeting with Stefan Jonsson FVB Sweden AB, were he explained the content of the project, and from this a presentation of the problem was made. The problem that needed to be solved was how they could control the valves in the system to provide heating to everyone in the system. The valves are often oversized so the pump in the heating plant would have to be enormous to be able to provide enough flow to be sufficient, if everyone in the system had there valves fully opened. I came up with two solutions to the problem, one was a wireless network that could keep track of the valves and the other solution was an extra sensor that was placed on the radiator.

Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

The Uppsala based company Q-linea develops procedures, instruments and systems for protein and nucleic acid analysis. The components in such an instrument are controlled by microcontrollers. Microcontrollers are computers in one singular chip that can be used in a wide range of applications such as cars, toys or in this case an analysis instrument. When developing a new instrument for biochemical analysis, Q-linea needed new software for controlling and communicating between the components in the instrument. The process of developing this software is the subject of this thesis.The project included research of microcontrollers and the components in the instrument.

Syftet med denna undersökning är att ta reda på till vilken grad olika teorier påverkar hur webbsidor uppfattas. Detta för att kunna utveckla mer tilltalande webbsidor. Vi valde att undersöka sex webbsidor: Aftonbladet, Nerikes Allehanda (NA), Dagens Nyheter (DN), IKEA, Hennes & Mauritz (H&M) och NetOnNet.Undersökningen är uppdelad i tre delar: en enkätundersökning, en expertutvärdering och en jämförelseanalys. Enkäten skickades ut till studenter vid Örebro Universitet via studentmailen och resultatet har sedan sammanställts i ett antal frekvenstabeller. Efter detta utfördes expertutvärderingarna utifrån litteraturstudien.

At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.

Society has an obligation to offer parents support of various types, an example of such a support is ?parent support?. The purpose of this study has been to describe midwives and child health care nurses conceptions of the need for early parent support. The definition of early parent support in this study is the first two weeks after delivery. Since the 1970:ies the Swedish delivery and ?BB? care has changed in that the time in hospital care after delivery has been reduced from in average six days, till an average of two days.

Rapporten som följer är en analys av en metod som genererar regler från neurala nätverk. Metoden heter VI-Analysis (Validity Interval Analysis) och är framtagen av Sebastian B. Thrun [Thrun]. VI-Analysis arbetar på det sättet att det neurala nätverket ses som en svart låda där endast de inputvärden och outputvärden som finns i nätverket används som underlag när regler ska genereras. Dessa inputvärden och outputvärden kommer sedan att få tillåtna intervall av VI-Analysis.
