Sommarhögskolans verksamhet : Ur ett learning-by-doing och elevperspektiv

This paper is written to take a close look at teaching methods used at the Summer Academy (SHS), which is held at Södertörns Högskola in Stockholm. SHS is a subdivision of the institution of teaching education, which annually, during summertime, offers an eight-day program for pupils between 13-15 years of age, from different schools located in socio-economically disadvantaged suburbs of Stockholm. The intention of SHS is to give the participating pupils an insight into higher education, especially that of university. The purpose of the activities, such as field trips, guided tours and corporate visits, is to make pupils aware of their own responsibility for their educational situation through different methods of knowledge transfer, to diversify the means of the education, and to bring awareness to the array of possibilities which they have access to within the Swedish system of tertiary education.The study is based on six deep-interviews, three with pupils and three with student mentors. Together with 131 surveys from the course given during the summer of 2014, and theories of John Dewey on ?Learning-by-doing?, the results show that pupils participation in SHS give them a better understanding for, and knowledge about their own educational responsibility.Another question this paper seeks to address is how significantly the SHS program is changing the pupil?s experience of education in general and their view upon higher education specifically.

Energieffektivisering av modern tillbyggnad till äldre skola : fallstudie från Österbyskolan i Österbybruk

The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.

Plusenergi och dess installationer : Kvarter Trettondagen

The latest thing in the area of environmental building today is energy-plus-house. The idea behind the energy-plus-house is to create a house that produces more energy than it consumes. To accomplish this, the house uses renewable energy, in this particular case solar energy. With the help from a proper construction and thoughtfully projected installations you can achieve a surplus of energy. The surplus energy can then be sold to the surrounding buildings and thereby conduce to a financial profit for the household.

Energieffektivisering av stenstadshusen - genom byggnadstekniska energisparåtgärder

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Implementering av realtidsvideolänk med MPEG- och wavelet-teknik

At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding.

Svenskars resemotiv till Egypten och Thailand

Purpose: My purpose of this study was to examine the factors that motivate Swedes to travel to Egypt and Thailand. To answer the question, I have used two questions.What are the factors that motivate Swedes to travel to Egypt and Thailand?What is the motive for Swedes choose to travel to destinations such as Egypt and Thailand?Method: The method I am using  is the qualitative method. The qualitative method has been processed through interviews of Swedish travelers, the Swedish travel agencies as well as Egypt and Thailand tourist agencies specializing in trips to Egypt and Thailand via phone and e-mail.Theory: The theory I am using are motivators and push-pull factors in achieving an understanding of the factors that influence choice for Swedes to travel to destinations such as Egypt and Thailand.Empiricism: The goal was to get a much more qualitative data from the response from the Swedish travel agencies, Egypt and Thailand tourist agency and Swedish travelers who have traveled to both of these destinations.Result: What I have come up with in my study is that the factors that motivate Swedish travelers to travel to Egypt and Thailand, is the warm climate, sun and sea, culture, variety, the cheap price situation and that there are activities for different age groups. This has led to the heat in both Egypt and Thailand has attracted Swedish travelers to travel to both destinations.

Kartläggning av spånprodukter vid Sävar såg

A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.

Miljö- och samhällsekonomisk analys av behandling av biologiskt avfall

Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

Omkonstruktion av armled tillhörande Bracke Forest högläggare

One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.

A foreign aid dilemma : a study of budget support versus project aid

Foreign aid is a very debated and controversial topic. The most recent studies have focused more on GDP growth and foreign aid correlation, however not much of the debate has focused on what kind of foreign aid should be given. The most common foreign aid is budget support, often a bilateral funds transfer between two countries. This kind of foreign aid can be both conditional and unconditional from the donors? perspective.
