Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

Detta examensarbete utgör resultatet av en studie på uppdrag av Volvo Cars Torslanda (VCT) i Göteborg. Syftet med studien har varit att undersöka produktflödena mellan VCT och dess leverantörer med hjälp av analyser. Dessutom utreds hur transporterna skulle kunna optimeras och vilka konsekvenser som uppstår. Beräkningar, diskussioner och analyser resulterar i rekommendationer för företaget.För att få mer kunskap om transportlogistik, produktionsekonomi och miljöpåverkan av transporter genomförs först en litteraturstudie. En granskning av nuläget beskriver hur situationen ser ut i dagsläget och ger även en detaljerad bild av flödena från leverantörer till VCT.Sex stycken flöden vars gods transporteras från leverantörer till VCT har undersökts.

Vid konstruktion och tillverkning av motorer idag finns flera krav att tillgodose i form av lång livslängd, låga utsläpp samt liten bränsleförbrukning. Dieselmotorn har högre verkningsgrad än bensinmotorn men problemet med dieselmotorn är i form av utsläpp där lagstiftningen blir allt strängare. En del av utsläppen från dieselmotorn kan bero på smörjoljan och olika motorer och ytor uppvisar olika mängd oljeförbrukning. Denna kan även variera mellan samma modell av motor. Ett sätt att få ner oljeförbrukningen och variationen av denna är att mäta ytan och säkerställa att denna är optimal för dess funktion.

The aim of this study is to examine which factors in a traffic wardens? situation at work that promote and which that inhibit satisfaction at work. The aim of this study is also to examine if there are any differences in the work experiences for traffic wardens that work alone versus those who work in a team of two. The following questions are examined in the study:?Which factors promote and which factors inhibit the work situation for traffic wardens??Are there any differences between traffic wardens that work alone and those who work with another colleague?The selection consisted of eight traffic wardens, of which four of them work with another colleague while the other four work by themselves.

Teching aid in form of schoolbooks plays an importent role. The teacher uses schoolbooks as a tool in its tutoring. I have examined how and whether the pictures in the schoolbooks are presenting people and ethnic minorities biased and stereotypical. The material I have examined consisted of a series of schoolbooks (So-direkt 1-3, samhällskunskap av Bonnier 2003).To find out if that is the case I have used a theory by Stuart Hall, his theory is about people and how they are represented in different types of media, like pictures and text. I studied it by using the method of image analysis where I investigated and interpreted the denotation and konnontation of the pictures.

This thesis focuses on the driver?s experience of the road and its surroundings. ?The view from the road? takes place every day and a high-quality ?road experience? is therefore a question of importance. Since cars made their breakthrough in the 1920-30, the approach to ?the driver experience? has varied notably.

The amount of cargo has since the 1970s increased in Sweden and the road traffic accounts for a large part of the transported volume. In Stockholm County the amount of cargo is calculated to be doubled in size from year 2001 to 2020 which means a greater need for transport is required. Much of these transports are being carried out by haulage companies of varying sizes which acts externally as carriers for their customers. All of this despite a greater awareness, laws and demands regarding environmental performance.The trend shows that the haulage industry in Sweden are moving towards fewer but larger haulage companies, which means that the competition is getting tougher for the smaller haulage companies. Smaller haulage companies and research about their competitive strategies is a neglected part of this industry.

This Masters thesis is made as the first of two visitor surveys of three urban forest areas. These areas are; Skutan recreational area in Haninge, Ugglevikskällan on Norra Djurgården in Stockholm and the Paradiset Reserve in Huddinge. The study is made in cooperation with the managers of the three areas operating within the European Union Life Project regarding Urban Woods for People. The goal has been to collect data through studies of visitors and close by residents in the three areas. The results are to be used as primary values for the follow-up as well as a basis for managerial decisions. The interviews and surveys are also constructed in a fashion so that they can be used for the follow-up study. For the Skutan recreational area the mode of contact was by sending forms to the nearby residential areas.

AbstractThe purpose of this paper is to examine how the population living in Christiania considers their residential area in relation to the surrounding society, and why you as an individual choose to live there. We have used the qualitative method and we have performed interviews with a total of six persons. We have used Tönnies two notions regarding gemeinschaft and gesellschaft, and Goffmans theory about stigma. We choose these theories because we thought that they were most relevant for our study. Our question at issue is: Why does a person seek to live in an alternative society, with different norms in comparison to the majority society? Through our interview persons we learned their stories and their opinions considering their residential area and we concluded that Christiania differs from the remaining society in several ways.

I samband med Transportstyrelsens införande av utökad B-körkortsbehörighet öppnades nya marknader för släpvagnar anpassade för transport av tävlingsbilar, verktyg och reservdelar. Sådana släpvagnar går att införskaffa sig idag på den svenska marknaden, dock är dessa endast anpassade för körkortsbehörigheten BE. Detta projekt utförs på uppdrag av företaget Fredrik Wagner AB, ett företag som designar och konstruerar transportband. Syftet med arbetet var att undersöka och utforska möjligheten för implementering av en ny släpvagnsmodell på den svenska marknaden. Målet med arbetet var att utveckla ett släpvagnskoncept anpassat för utökad B-behörighet, och därefter designa en CAD-modell av konceptet.Information om bilsporten och marknaden samlades in för att definiera och förstå problemet bättre.

ModFix är ett verktyg som är integrerad i Siemens simuleringsmiljön Process Simulate och används för att skapa modulära fixturer. Målsättningen med arbetsmetoden där fixturer skapas med ModFix är att ledtiden och mantimmarna för att skapa fixturer ska reduceras med 50 % i jämförelse med Volvo Cars nuvarande arbetsmetod där fixturer skapas med Catia V5.ModFix-verktyget består av tre funktioner. Dessa funktioner är; Configuration Administrator, Fixture Designer och Modular Fixture Mapping Report. Configuration Administrator är ModFix´s administrationsverktyg och används för att skapa de fixturbaser och fixturkonfigurationer som senare används för att skapa modulära fixturer med Fixture Designer.

Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.
