This study was made for the round wood transport company MT Transport AB. Time studies were made in order to analyze time consumption on the mill site for timber trucks delivering round wood at the Södra Cell Mörrum mill. The most interesting was to see how much of the time spent at the factory that was waiting time. In three weeks the study was going on and the drivers were clocking it themselves..

 Autonomous cars or robot cars havebeen on the agenda ever sinceHollywood started with their Sci-Figenre, maybe even before that. A lotof things have happened since then andnow the self-driving vehicle is notfar away. In this project, theAutonomous car with microcontrollerand ultrasonic sensors, we are lookingat a way of making a small, regular RCcar autonomous with relatively simplemeans and investigate how the bigcompanies does it to learn more aboutthe development of the autonomous carsand their technology.We used an Arduino Uno R3 supplementedwith an Arduino Motor Shield R3 as ourmicrocontroller board and three HCSR04ultrasonic sensors. By removingalmost all of the old parts of the RCcar,except the two DC motors, andreplacing them with these new parts wemanaged to make a vehicle that drovearound in a room without crashing intoanything. We could have used entirelydifferent sensors, or supplemented theexisting setup with other sensors tomake it even more accurate andobstacle avoiding.

This masters thesis takes the providers perspective on public library story times for children. The main questions are: What perspectives can the providers have? How does the perspective affect the content and how is the story time drawn up? Five story time providers were interviewed about the purpose of their story times, the methods they used and the content they chose. A model with four criteria was used to analyze the result of the interviews. The criteria were: adult criteria, consideration of the childrens view, pedagogical criteria and literary/story time criteria.

The study aims to contribute knowledge about children's perceptions of the leisure-time as a learning environment. The study can be seen as an attempt to highlight the possible learning in the leisure-time, formally or informally.The study is based on two group interviews with a total of 11 children and was conducted by an interview guide with question areas to be discussed freely so that the children could give as full an answer as possible.Main results of the study show that children feel that they are staying at the leisure-time to get care when their parents are working and that they primarily associate the leisure-time with playing. The results show however that children feel that they learn things when participating in the leisure-time teaches controlled activities.It is possible to draw conclusions about the child actually experienced the leisure-time as a learning environment, but it can be difficult to identify when and how learning actually occurs. However, children do not perceive that there is learning while they play..

The use of silicon carbide (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been to develop a test method and verify the functionality of SiC powertransistors prototypes with a new packaging technique developed by Swerea IVF AB.It includes setting up an electrical test-bed for power and high temperature cyclingand analysis of the results. Even though test confirmed functionality after thepackaging process, (at room temperature) the performance seemed to have been reduced. This could be a result of the measurement setup and the packaging process.In higher temperature the transistors failed to operate longer than a couple ofminutes which showed the weaknesses in the design and the challenges with this typeof packaging..

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

The purpose of this study is to explore active after-school teacher?s perceptions of the concept of meaningful leisure time. The purpose of the study is also to investigate if the interpretations of meaningful leisure time affect the perception of their work roles and after-school teacher?s actual work in a leisure activity. The study also provides an insight into how afterschool teachers perceive their roles in general.

Syftet med studien är att få djupare insikt i sångpedagogers syn på Time och Sväng samt hur de didaktiskt arbetar med dessa aspekter. Det saknas mer omfattande forskning inom området. Med detta i behåll har jag för avsikt att få djupare insikt i frågeställningar som rör olika förhållningssätt till hur sångare kan öva upp Time och Sväng samt vad Time och Sväng innebär, generellt och i ett undervisningsperspektiv. Studien har som sin teoretiska utgångspunkt ett sociokulturellt perspektiv med fokus på hur människor använder olika redskap för att kommunicera med sin omgivning.För att få svar på mina frågor har använt mig av en halvstrukturerad intervjuform när jag samtalat med informanterna. Alla informanter i denna studie arbetar idag som sångpedagoger; två av dessa är mer inriktade på jazz medan de andra två är mer inriktade på populärmusik.

In this report we describe an adaptive simulated annealing method for sizing the devices in analog circuits. The motivation for use an adaptive simulated annealing method for analog circuit design are to increase the efficiency of the design circuit. To demonstrate the functionality and the performance of the approach, an operational transconductance amplifier is simulated. The circuit is modeled with symbolic equations that are derived automatically by a simulator..

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.
