Simuleringsprogram som verktyg vid projektering av solvärme

The government regulations for energy use in buildings will be tightened in the future. At the same time the interest in environmental classifications and certifications of buildings is increasing. This has meant a new situation for solar energy. The designs of solar heating systems are often based on experience and/or rules of thumb, rather than calculations and simulations. This thesis examines whether simulation tools, in this case Polysun, are useful in this work.

Brunstvisningsförmåga hos mjölkkor- en beteendenstudie

Oestrus in dairy cattle has changed over the last decades; the intensity of oestrus has declined and the duration decreased. Several studies have shown that not all dairy cows stand to be mounted, and that oestrus expression in many cases may be characterized by other behaviours. The aim of this study was to investigate oestrus behaviour in a herd of todays? high producing dairy cattle. The study was carried out at Jälla naturbruksgymnasium in Uppsala during one week in January 2011.

Amongst other things,coconut oil has been said to lower cholesterol (1, 2). This despite the fact that coconut oilcontains of 92 % saturated fat, which strong scientific evidence support raises the blood lipidsand thus increases the risk of cardiovascular disease (3).Objective: To examine the scientific evidence for how blood lipids in adults are affected byan intake of coconut fat compared to an intake of other kind of fats.Search strategy: PubMed and Scopus have been used in the literary search. Keywords usedwere "coconut fat", "coconut oil", "plasma lipids" and cholesterol [MeSH].Selection criteria: Human studies of RCT or cohort type, published since 1983.

Teknisk analys : Är det lönsamt att vara trendig?

Trading based on technical analysis has its roots in the U.S. financial industry where it has long been common practice, in Sweden however the trading style has not had the same impact. Based on the results from the preliminary study we believe this is about to change and that the topic therefore requires further studying. Several online stockbrokers today provide information and tools for technical analysis to their clients. As the list of indicators to use for creating strategies is so immense it is interesting for an investor to know what actually could be the basis for a profitable investment strategy.

Styrdokument i musikämnet : ? En komparativ studie av norska och svenska styrdokument i musikämnet i skolan.

Abstract:Styrdokument i musikämnet-En komparativ studie av norska och svenska styrdokument i Musikämnet i skolan.(Music Subject governing documents- A comparative study of Norwegian and Swedish policy documents in the Music subject in school)The purpose of this study is to compare the Norwegian and Swedish policy documents on teaching in the Music topic. The Comparison also applies to the requirements which have been in Sweden over time. In Comparison, the policy document LGR 11 from Sweden, analyzed, and the governing documents MUS1-01 and R94 from the Norwegian School.The main issue in the study is: How does the policy documents for the topic music in Sweden, compared to Norway? In order to answer the question, I compared the above-mentioned policy documents and set in relation to the musical substance is designed in Norway and Sweden.In curriculum theory treats one problem based approaches in structural functionalism, pragmatism, social epistemology and post structuralism. The starting points are then used to explore various relationships between curriculum theory and didactics.The principal researcher and proponent of curriculum theory is Ulf Lundgren.

Aktivitens betydelse för åldersrelaterad kognitiv försämring

The current paper compares the relations between different measures of activity and some common neuropsychological tests. One-hundred and fifty five healthy elderly, aged 55 - 85, living in Sweden were included. Gender-specific patterns were found for both activities and correlations between activities and cognitive measures. The main findings suggest that activities are associated with cognitive speed in men, whereas, for women, active and passive activities correlate, positively and negatively accordingly, with education. In Comparison, complex models of activity outperform simpler ones and theory-driven measures just barely outperform intuitive models..

Delta X : Utveckling av värmeväxlare

Stockholms vattenskärning AB in Kungsängen has through the acquisition of a company begun to design and produce aircraft heaters whose origin is early 1970s which follows a high inefficiency in terms of energy consumption and size.The aircraft heater, which is sold worldwide, serves its purpose for customer satisfaction and has done so ever since it was developed in the 70s.Stockholms vattenskärning AB is now investigating the possibility in making the aircraft heaters more efficient, both in terms of energy consumption but also on a more efficient design with the belief that it would lead them to an edge in the market. The aircraft heater consists of several main components whose function altogether is to keep passenger aircrafts warm while they are on the ground.This project has been limited to the further development of the heat exchanger package which accounts for the conversion of the hot medium to the fresh air being carried in to the aircraft cabin. Work has been divided into different phases in order to create a better understanding of the project range and to make it easier to divide the various elements in the time available, 10 weeks. These phases are literature review, situation analysis, concept generation, CAD, concept Comparison and writing reports.After the initial literature review was made, a fundamental theory was written which is essential in understanding the remaining parts of the project.With the theoretical part as support, measurements and calculations were made on the current heat exchange package in a situation analysis to ensure its operation and efficiency.In the concept generation phase, the collected facts from the literature review was used as the basis for creating a matrix. The purpose of the matrix was to indicate the two most suitable types of heat exchangers to develop four new concepts out of.In the CAD phase the four concepts was drawn up and then described with text and images.The last phase is the concept Comparison where a concept selection matrix is used to function as a decision basis for further production at Stockholms vattenskärning AB. The four concepts have been developed based on the current heat exchanger and is gradually changed into a design of a cross-flow heat exchanger constructed out of stainless sections. The purpose of this is to have gradual upgrading of the heat exchanger as an option, in order not to saturate the market..

Systemutveckling av Trouble Report : Hur väljer och prioriterar man tekniska funktioner i vidareutveckling av ett etablerat system?

As part of an internship at Ericsson, this report was written to enhance the understanding of how it is to develop a system that is well established at the workplace. To improve an already existing system is not always as easy as many developers may think. In this report the pros and cons of developing an already existing system has been researched and analyzed. Do note that the results are only from one development of a specific system and that Comparison of other developments has been made from other reports and not from experiencing it firsthand. It was found that the choices made can have an impact on further developing and it is important to write down what has been done.

Tillväxt och potentiell sågtimmerkvalitet i gallringsmogna jämförelseplanteringar med Pinus contorta och P. sylvestris :

The Swedish Cellulosa Companiy, SCA, has today 280 000 ha planted with lodgepole pine (Pinus contorta var. latifolia) (?C?) which is equivalent to 14 % of its total forest area. Exotic lodgepole pine has in previous experimental stands shown a superior growth than the native Scots pine (Pinus sylvestris L.) (?S?).But also the Comparison could be questioned because stand histories were was unknown and also differences in age between C and S existed.

OMBYGGNAD AV TRAFIKPLATS : Ekhagsmotet i Jönköping

We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.
