This report is part of a Bachelor?s degree corresponding to 15 creditsat the Royal Institute of Technology, Stockholm. The work hasbeen carried out by Max Wikander, author of the report, supervisedby Lanie Gutierrez-Farewik and Erik Dijkstra.Gait analysis includes measurement, characterization and assessmentof human movement and is used to assess kinematic or otherabnormalities during gait. Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.

Många människor faller in i ohälsosamma livsstilsmönster som kan vara svåra att ta sig ur. Bristande hälsa kan ofta relateras till felaktig kost, för lite motion och/eller sömnstörningar. För att göra en förändring kan det vara nödvändigt med professionell hjälp, där motiverande samtal kan vara en användbar metod. Syftet med vår litteraturstudie var att undersöka möjligheter med och effekter av motiverande samtal vid livsstilsförändringar, främst beträffande kost, motion och sömn, samt att undersöka sjuksköterskans möjlighet att använda sig av denna metod. För att få svar på syftet har vi granskat 16 vetenskapliga artiklar beträffande motiverande samtal, kost och motion.

This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

Ericsson?s factory in Kumla, Modules Kumla, became a hub for radio modules and micro base stations, which enables mobile communication through radio base stations, in 2004. Because of this the factory focuses more on the logistics operations. This has led to a need to be able to plan the capacity for the materials handling system. This master thesis has therefore been performed at Modules Kumla to develop a capacity calculation model for the material handling flow during the autumn of 2005.The work has contained a mapping of the material handling flow regarding to which activities was performed and how much time they consumed.

Together with NCC and Sweco we measured the air-flow on a semi-detached house in Jönköping. When a pressure measurement is made, the house gets exposed to over- and under pressure. This is done in order to examine the houses climate shell. The climate shell of the semi-detached house we tested exceeded the required air thickness in BBR-2002, hence, measures have to be taken.This report also displays the importance of building air thick houses and what consequences a non air-thick house can have for the ones residing the house. A discussion of different measures is on for the addressed problems with the flow-measurement and the alternative construction-solutions.Furthermore we have described in this report of how to account for the performance of the air pressure, what kind of equipment we used and how we came up with the results.

The purpose of this report is to survey Swedex AB?s production costs and to gather all info into a manageable calculation tool. This was made by time and motion studies, interviews of the personnel. All factors were gathered into an Excel chart.The calculation was made according to an additional-charge-method that was considered to satisfy Swedex AB?s goal.

 This study was conducted in autumn 2008 on the Company AB, which is currently in a growth phase. The company manufactures hydraulic systems for the heavy vehicle industry and has annual sales of approximately 250 MSEK with 165 employees.The rapid growth and unchanged planning is the starting point for this report. It all began in 2005 when the company received an unusually large order. During this period, the first priority was to satisfy customers and all other focus was disregarded. This has primarily resulted in a messy production and long throughput times.

Syftet med denna uppsats är att utreda vilka faktorer som påverkar de svenska småhuspriserna, och i så fall hur och i vilken utsträckning. Med stöd av tidigare studier som enhetlig pekar ut bolåneräntan och disponibel inkomst som de faktorer vilka har tydligast inverkan på fastighetspriserna i Sverige, utökas de förklarande variablerna i denna studie med hjälp av en stock-flow modell. Tidsseriedata från 1993-2013 behandlas för enhetsrötter och kointegration för att skattas i en regressionsanalys i form en "Error Correction Model", med avsikten att utreda både ett kort- och långsiktigt samband. Resultatet bekräftar reporäntan och disponibel inkomst som två viktiga faktorer för att förklara det långsiktiga sambandet med priserna på småhus i Sverige, tillsammans med ytterligare faktorer såsom BNP, hushållens skuldsättning och arbetslösheten. På kort sikt är dels den historiska utvecklingen av huspriserna en nyckelfaktor, men faktorer som disponibel inkomst, ränta, BNP och hushållens skuldsättning är också viktiga krafter för att förklara småhuspriserna.

Handling product returns has become a critical activity for organizations as the volume of gods flowing back through the supply chain rapidly increases. Few research studies have published specific empirical data concerning the reverse logistics practices of companies. Information technology and information support has long been recognized as a competitive weapon ? capable of enhancing company performance and achieving efficient reverse logistics. Reverse logistics is very unlike the forward, as it is more reactive and also has less visibility.

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

In this project forging of aluminum alloy Al 6026 T9 has been performed in the temperature range of 400 °C ? 470 °C. The alloy which was in the shape of a cylindrical billet was formed in a press with the aim of analyzing the effect of different forging temperatures and required press load for optimal die filling. The component?s dimensions were later measured and compared to a reference piece.

Studien undersöker känslomässiga reaktioner vid kooperativt spelande, vilka som är gemensamma för båda spelarna och hur de påverkas av hur svårt spelet är. Arbetet utgick från studier av spelares emotionella reaktioner på spel och teorierna om Flow. Spelet Sanctum användes i en serie tester där mätningar utfördes på två spelare med hjälp av rapportformulär, pulsmätare och hjärna-till-datorgränssnittet Emotiv EPOC. Studien fann att spelarna ibland upplevde samma känslor när de spelade tillsammans och att den ökade svårighetsgradens huvudsakliga effekt var att förändringarna i känslorna blev skarpare och större. Det tycktes huvudsakligen vara motgångar som splittrade spelarnas upplevelser.

Problems arise when the number of products in stock does not correspond with the number of products the information system says the company has in stock. (Sharda & Agrawal, 2012) In order to change that, major changes has to be made when it comes to making continuous improvements and to raise their standards regarding product availability and record inaccuracy (Wild, 2004).The purpose of this study is therefore designed to identify factors affecting the balance differences and what impact it has on the efficiency of material flow. The demarcation of the work is that Atlas Copco has begun working with Lean and it will not be investigated nor the relationship between balance differences and Lean. The study was based on answering the following questions: What influencing factors can be identified for balance differences? What factors are relevant to the efficiency of material flow? What kind of impact the balance differences has on these factors?In order to answer the purpose and issues, a theoretical framework has been developed with help of literature studies and an analytical model.

To the sewer systems households, industries and other activities are connected. The wastewater is collected at treatment plants where a nutritious sludge is produced. The sludge does not only contain nutrients, but also hazardous substances originating from different activities in society. To reduce the flow of hazardous substances to treatment plants and to create a sustainable recycling of plant nutrients the Swedish Water & Wastewater Association has developed the certificate system REVAQ. This certificate requires a good quality of the sludge but also that the treatment plants maps the origin of the unwanted substances.
