This master thesis was performed at Scania Research & Development. The given mission was to see where the department Systems Development should focus to improve their development work. Thus the purpose was to map the product development processes in which the department works today and within them identify improvements. To fulfil the purpose a theoretical study of relevant terms, such as improvement work, product development and processes, initially was formed. The mapping method used is called "walk trough" and meant to let the people working in the processes be guides in their own process.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..

A performance measurement system can be used as a means to evaluate past performances and to communicate prioritizations. It has also been proposed that a performance measurement system can serve as a method to execute strategies, guide in operational decisions and constitute a tool for making the organization more efficient. Yet one may question if such a system will ever reach this capacity if operating managers do not utilize it as a management tool, but rather treat it as a mere report in the bunch. This paper explores how middle managers in fact apply performance measures and what obstacles there are to integrating them in the management of subunits. Furthermore it serves to investigate whether these managers experience a conflict between how they are expected to use the measures and what they deem possible to adopt.

The purpose of my work is to understand and examine the reasons why Ethiopia has not developed a larger decline of female genital mutilation, despite their ban on it? A ban that has been operating for ten years should reasonably have reached a greater change than the one Ethiopia has developed today. Based on two different branches of feminist theory, the liberal feminist theory and radical feminist theory, I will try to understand the potential power relationship that can be a immense reason for Ethiopia's continued practice with regard to female genital mutilation. I will examine the liberal feminist approach when it comes to seeing the state as the source of the balance of power that generate inequality in the world between men and women. I will also apply the radical feminist theory on my case study and understand the problem of patriarchy and its already set roles for men and women that we are following in the society today, resulting in gender inequality. The result shows that the radical feminist approach with patriarchy as essential explanation, which articulates that because of ancient traditions and the exercise of power, the amendment must be the changing of power relations between men and women in the private sphere rather than the liberal feminist approach which applies that the state repair the problem..

Sammanfattning: Detta självständiga arbete har utifrån ett taktiskt perspektiv studerat på vilket sätt obemannade system i kategorin UAS, Unmanned Aircraft Systems, kan tänkas bidra till taktisk uppgiftslösning inom marinen om dessa infördes idag. Arbetet har genom kvalitativ litteraturanalys studerat utvecklingen av dessa system och vad som är rimligt att förmågemässigt förvänta sig av dem idag. En analys har gjorts av den för arbetet aktuella operationsmiljön, den kvalificerade sjöstriden. Vidare har en analys av hur utvecklingen av UAS i USA och Ryssland gjorts för att sätta ett svenskt system i en kontext. Arbetet har haft sin grund i teorin om sjökrigets principer då dessa ger en god teoretisk grund för hur sjöofficeraren bör agera.Slutsatser som redovisas i arbetet är att UAS kan komma att spela en stor roll i att ge ökad förmåga till god lägesuppfattning för marinens taktiska chefer.

Syftet med denna uppsats är att undersöka hur en grundskola arbetar för att implementera studie- och yrkesvägledning i vid bemärkelse, som hela skolans ansvar. Styrdokument beskriver att skolor bör arbeta med studie- och yrkesvägledning på ett långsiktigt och individanpassat sätt för att ge elever möjlighet att göra väl underbyggda val i framtiden. Ändå visar olika granskningar att utbudet av studie- och yrkesvägledning i grundskolan många gånger är bristande och av varierad kvalitet. En grundskola i Skåne arbetar i nuläget för att implementera studie- och yrkesvägledning under lektionstid, som ett projekt i skolorganisationen. Projektets implementering ska leda till att skolans elever ska få verktyg för framtida val men även att skolan aktivt ska arbeta med studie- och yrkesvägledning som ett gemensamt ansvar. Undersökningen genomfördes med en kvalitativ metod där intervjuer gjordes med fem lärare och en studie- och yrkesvägledare alla verksamma inom den undersökta skolorganisationen.

The study aims to investigate the impact of industrialised homebuilding in the creation of the aestheticproperties of the dwelling architecture.The concepts of industrialised homebuilding and the aesthetic properties of the dwelling architecture aredefined by previously developed models. In these models, industrialised homebuilding is described byeight characteristic areas. The aesthetic properties of the dwelling architecture are described by sevenaesthetic qualities.The study was conducted as a qualitative study, and in-depth interviews were conducted. The companyJM AB is the analysed unit that the author of this report has chosen to study. JM employees and by JMhiredarchitects were interviewed.The report concludes that characteristic area planning and control of processes are considered to havepositive impact on the aesthetic qualities if the process is designed in such a way that the creations ofthese are admitted.

Stridsfordon 90 är ett militärfordon som BAE Systems Hägglunds i Örnsköldsvik har utvecklat och startades att produceras år 1993. Fordonet vidareutvecklas och tillverkas än idag och på grund av ökade krav på skydd och eldkraft har fordonets tjänstevikt ökat kraftigt. Från den första versionen av fordonet, Mark 1 (ca 23 ton) till senaste versionen Mark 3 (ca 35 ton). Den ökade vikten påverkar en rad av olika komponenter i fordonet och dess prestanda men det är framförallt drivlina och fjädringssystem som påverkas mest. Fordonet har i sin drivlina slutväxlar som växlar ned rotationshastigheten från motorns transmission och överför på så vis ett ökat drivmoment ut till drivhjul och band.
