This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.

I denna uppsats redovisas en benchmarkingstudie i syfte att jämföra Sveriges försvar mot ett urval av andra länders försvarsmakter, nämligen EU- och NATO-länderna samt Schweiz. Studien har skett med avseende på kostnadseffektivitet och fokus på output i internationella insatser, som har kommit att vara allt mer prioriterade i västvärldens försvarsmakter under senare år. Vidare genomförs en kvantitativ jämförelse mellan värnplikt och andra personalförsörjningssystem genom att länder med likartade personalförsörjningssystem förs samman i fyra kategorier: värnpliktsbemanning av stående styrkor, värnpliktsbemanning av mobiliserande styrkor, blandsystem respektive professionella styrkor. Kategorierna särskiljs genom kvantitativa data, dels andelen värnpliktiga i de aktiva styrkorna, och dels storleken på reserverna i relation till de aktiva styrkorna. Två olika outputmått har utnyttjats, dels faktisk personalvolym i internationella insatser, och för EU-länderna också storleken på de styrkebidrag som utlovats till EU:s gemensamma insatser.

The following study aims to investigate the environmental conditions of the harbor of Sk?rhamn, a small fishing community on the west coast of Sweden. The interest to do so rose as a newly built apartment residence failed to connect the sewage pipes of 18 apartments, causing the untreated sewage running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

The idea to create authentic learning situations where students are highly integrated made me want to try to develop a new method in the course Restaurant and Catering B MAKU 1208 (another field practicing cuisine). In my quest to do just the practical part as rewarding, stimulating and efficient as possible for the student, I planned for a training model with   focus on group interaction.The implementation of the model for learning was to strengthen students confidence both in themselves and in each other, stimulated to greater cooperation and it has also provided an incentive to the student's own development but not least, a growing self-confidence for many students. Several have also had an increased sense of knowing something, to have something to contribute and that their labour input actually was needed. While highlighting that further education to seek knowledge strengthens the individual's skills and consolidates and increases deeper knowledge in the professional field.In conclusion, training should be done in both individual and group basis for optimal learning process..

Our digital society encompasses nowadays different channels, which includes social media where many users consider it as a platform where they can fetch news or exchange news and information. This leads to a large spread of news exchange in a very fast speed, which involves the global users within social media to be a part of this social interaction. This study is focused on how Twitter affects the usage of the user?s news consumption. By reaching out to our specific target audience, which includes Twitter users in Sweden, we made a web based survey with a content of relevant questions.

Recent changes in Swedish law suggest new groups of ?desired? labor migrants, which international students is an example of. Despite this, international students in Sweden have received little previous attention in the literature. The current study focused on international master students? experiences of job searching in Sweden and challenges they face in job searching, recruitment, and workplaces.

This paper discusses the advantages and disadvantages of using different benchmarking models to measure and compare the efficiency of Swedish gas distributors. It also discusses to which extent the results of a benchmarking study should influence the revenue-cap which will be implemented in the gas distribution sector in Sweden from year 2011. The discussion is based on arguments from both theory and practical applications of benchmarking. The results suggest that benchmarking Swedish gas distributors against distributors in another country using a parametric model is most favorable, but the reliability will be increased if non-parametric models are used also. Partial and total productivity measures could be used to confirm results of other benchmarking analyses.

Syftet med den här uppsatsen har varit att undersöka fyra gymnasieelevers erfarenheter av språkundervisning i moderna språk. Uppsatsens frågeställningar är: ? Hur beskriver eleverna sin språkundervisning? ? Vilka strategier använder sig eleverna av vid språkinlärningen? ? Vilka teorier kring lärande går att observera i elevernas undervisning? Underlaget till uppsatsen har varit fyra gymnasieelevers utsagor om språkinlärning i form av kvalitativa intervjuer. Elevernas utsagor har analyserats med hjälp av olika teorier med anknytning till språkinlärning. Slutsatsen är att denna språkundervisning lägger tonvikten på den sociala interaktionen, vilket speglar den forskning som har gjorts de senaste 30 åren. Det visade sig även att det fortfarande finns spår av äldre metoder i dagens undervisning, och att det är problematiskt att hitta en balans mellan lärarcentrerad och elevorienterad undervisning..

Syftet var att undersöka om exponering inför emotionella röster påverkar muskelanspänning och hjärtats slagfrekvens samt om det finns en samvariation mellan storlek eller längd på muskelanspänning vid aversiv emotionell input och grad av alexitymi. 24 studenter lyssnade på arga, glada och neutrala röster samtidigt som muskelanspänning mättes med EMG och hjärtats slagfrekvens med EKG. Grad av alexitymi mättes med Toronto Alexithymia Scale 20. Resultaten visade att arg eller glad röststimuli gav större muskelanspänningen än neutralröststimuli. Ingen skillnad i muskelanspänning fanns mellan arg eller glad röst.

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

Background: During the last decades patient satisfaction has become an important measurement of quality in psychiatric care. However the patients are seldom asked to evaluate the treatments.Objectives: The aim is to determine which factors the outpatients regard as beneficial in their psychiatric treatment. The purpose is explorative. During the study another purpose developed; to present research on the importance of the relationship between the caretaker and the caregiver for the outcome.Method: 30 persons were interviewed about what they found helpful in psychiatric treatment. The interviews were open using Grounded Theory as methodological input.Result: The most prominent topic was the quality of the relationship between the caregiver and the caretaker.

Studien ar en analysering av omskrivningsregler framtagna av Decker (2003), dessa omskrivningsregler har implementerats i ett verktyg som heter CogFLUX. Syftet med dessa omskrivningsregler ar att forenkla det svenska spraket och gora det mer lattlast. CogFLUX tar en given text som input och omskrivningsregler valjs ut och appliceras pa texterna med hjalp av verktyget. Detta verktyg returnerar sedan en omskriven text och de tre olika lasbarhetsmatten LIX, OVIX och NR for texten. Syftet med studien har varit att se huruvida olika permutationer av en given uppsattning omskrivningsregler ger olika resultat matt med lasbarhetsmatten samt om det finns kombinationer av omskrivningsregler som fungerar battre an andra.

At Volvo Cars Torslanda's paint shop there is a requirement to in a fast and effective way get an overview of the plants capacity. Therefore a capacity template was constructed as a tool for the engineers at Volvo several years ago. This template has during the years become complicated and outdated. Thus this thesis work will resort as a new capacity template, built from scratch. The new template has been built up based on requirements from Volvo and the concept of OEE (Overall Equipment Effectiveness).
