Katana databas 1.0
The task to this thesis has been to create an application, Katana-databas 1.0, for analysing c-code. The generated output gets stored in a data structure which content in the end of the program run gets written in a textfile which gets used by Katana. It's a tool for reverse engineering, developed by Johan Kraft at Mälardalens institute.Katana-databas has got the following limitations. (1) It can only handle preprocessed files, meaning it doesn't contain any rows beginning with "#". (2) Only complete files can be handled.
Synsätt på barn och barnboken. Vilka signaler har barnbiblioteken fått under 1900-talet?
The aim of this masters thesis is to examine what intentions handbooks, laws and regulations have had about children and childrens literature, as we think that they can serve as guiding principles for childrens libraries in Sweden. The questions are: what signals have the childrens libraries got from the documents concerning the view of children and childrens literature during the 20th century? What has the social opinion about children been during the 20th century? How have children been seen during the 20th century? The method we used is a qualitative source analysis of mention above documents seen from a hermeneutical point of view. This analysis is woven together with the social opinion on children during the 20th century. Our results show that the aim of childrens literature before 1945 was a pedagogic and moral one.
Undersökning av självspridning av contortatallen i norra Sverige
Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions.
A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.
Solel till Akademiska sjukhuset : möjlig genererad effekt och solcellers estetiska konsekvenser
Today many buildings and it´s nearby surroundings are designed to achieve some kind of environmental goal.The issue concerning energy consumption is currently at focus and it is relevant that we start increase the share of renewable energy. Solar energy is an infinite resource and should therefore be considered when selecting an energy supplier. Uppsala University hospital is facing major restructuring when parts of the existing buildings will be refurbished and a large new building will be constructed. White Architects have developed a study concerning the new building and for some of the existing buildings on the hospital campus. Uppsala County requires tough energy measures and wants the new building to be classified as an eco-building in Whites following work. The classifications will involve high energy source requirements. This work has been conducted to see if solar power can be envisaged as a supplementary energy source for the University hospital and also to investigate the aesthetic impact of solar cells on the new building.
Castrix : Utveckling av webbsidan Sundsvall42
The goal of this Bachelor project was to develop the Sundsvall42 website,whose name originates from the conference held in week 42 and during whichall the IT-companies in Sundsvall gather and hold a number of different lectures.The website has been designed to accommodate both speakers and partipicants.All partipicants and lecturers will receive a personalized page inwhich there are a number of functions which are available for use, including ablog for each workshop and a calendar. The program used to create this isLiferay and the operating system is Linux. The entire website is encoded usingLiferay and Java, but the website is not adapted for use with the smaller screensize of the Smartphone. However, because of the Responsive Design technology,the website is able to adapt to various devices such as the Ipad and Smartphonesand the website will be able to adapt to the screen sizes of these devices.As it has all been processed using open-source, everyone has the right to accessthe source code. It is also possible for anyone to make changes to the code ifsuch changes are required.
Vallört som växtnäringskälla : växtnäringsförsök och litteraturstudie
Russian comfrey, Symphytum x uplandicum, was tested as a plant nutrient source in a trial with tomatoes. Comfrey liquid was produced by Stiftelsen Holma i Höör. Tomato plants of the cultivar Aromata planted in a medium of soil:peat (1:1) enriched with organic nutrients and lime, were fed with comfrey liquid plus Biofer, in three different concentrations. Two different concentrations of BioRika were used as comparison, along with an unfertilized control group. In the comfrey treatment I a total amont of 1g N, 0,23 g P, 0,84 g K, was given to the tomatoes.
Den Sociala Identitetens Inverkan På Subjektiva Bedömningar Av Att Dela Värderingar Med "Andra" - En psykologisk analys av motstridiga uppgifter i Integrationsbarometern 2004
This study examined some contradictive results in a report from the Swedish board of Integration. The contradiction was concerning the Swedish populations dismissive judgments of experience a shared ground of values between the Swedish society and those witch are generally held within Islam. These dismissive judgments were given at the same time as the population reported to have a lacking knowledge of Islam in general. To test for psychological aspects of these contradictions, the analysis was based on the theoretical ground of Social Identity Theory and Theory of Attributions. The study used an existing survey that examines people´s estimations of their own and other members of society´s fulfilling of democratic values.
KORTSIKTIG PRODUKTIONSPLANERING I MINDRE FJÄRRVÄRMESYSTEM : En studie vid Strängnäs Energi AB
District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.
Rocchio, Ide, Okapi och BIM : En komparativ studie av fyra metoder för relevance feedback
This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

Analys av sorptiv kylning i industri- och kontorsbyggnader
Energy efficiency is important both to reduce costs and to reduce greenhouse gas emissions in the atmosphere. Reducing costs will also help maintain business competitiveness.Scania in Södertälje is a company where the optimization of energy use is an ongoing and continual process. One area with potential to make energy and cost savings is the effectiveness of the ventilation systems in offices and industrial premises at Scania. During the summer months an increased demand for cooling occurs, leading to increased ventilation and a peak in district cooling system usage. Sorptive cooling is a technology where the supplied air is cooled by applying external heat.
