Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

Projektet grundar sig i grannarnas motvilja till en kontroversiell byggnation vid Högalidsparken. Parker är som regel inte bebyggda och bebyggelse med bostadskaraktär minskar parkens offentlighet. Detta förslag bidrar med att utöka parkens yta och genom att hålla bygghöjden låg, fortfarande bibehålla grannarnas utsikt över parken. I Stockholm råder också brist på utrymmen där flyktig eller säsongsbetonad handel kan ske innomhus, därför innehåller förslaget även en marknad inriktad främst till privatpersoner och små företag..

In the year 2002 the European Union decided on a new directive according to the energy use in buildings. The outcome of this direction is a proposition from the Swedish government on the outlines of a new law in the field of energy use in buildings. The date that the law will be applied is the first of October 2006. In the future al real estate owners must be able to show an energystatement over the real estate. This project contains cooperation with HFAB a local real estate company where two buildings are analyzed according to their energystatement.

Computational thinking was brought to the forefront in 2006 by Jeannette Wing. Computational thinking is a problem solving method that uses computer science techniques.The thesis is analyzing computational thinking and how it could be applied to graph theory. Characteristics and main fields from computational thinking is being analysed. This analysis is applied to graph theory to see the potential in developing a proposal for how an exercise can look for an introductory course in discrete data types. Only basic knowledge of graphs is required to perform the exercise.

Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

This paper presents the results from an osteological method study of the Ringsjöholm fishbone material. Ringsjöholm is located in Scania, southern Sweden and is 14C dated to 5960-5200 B.P. The aim of this paper is to critically analyse methods used on fish bone material in estimations of season. Three different approaches were used to estimate the fishing season at the Ringsjöholm settlement; 1) identified species, 2) size estimations of the pike based on Enghoffs (1994-95) regression formulae of os dentale, and 3) growth rings of the pike vertebrae.The identified species and the size estimations of the pike points to the fishing being active both during spring and summer. Growth rings analysis of the pike vertebrae didn?t give any quantitative results because of fragmentation.

We came in contact with the project "Grönplan Danderyd" that aims to create a green structure plan for a municipality of Stockholm called Danderyds kommun. Our thesis is a part of this project and makes it's contribution through the gathering and systematization of the knowledge of the functions of an urban green structure. It also makes a contribution through suggesting how this knowledge can be applied during the construction of an urban green structure plan. We found that "Stadens parker och natur", published by the Swedish National board of Housing, Building and Planning, was a recurrent source of information in the green structure plans that we studied. We saw a need of complementary additions and updates to the rather old report and found literature that adds the developments of the last decade. First of all we have chosen to make themes based on the functions of a green structure that were presented by 'Stadens parker och natur'. The themes we suggest that a greenplanning document manage are: Recreation, Pedagogies and Heath, Biological Diversity, Green structure in the History of Building Cities, Cultural Identity, the Health of the City, Biological Technology in the Municipality and Use and the Users. We found good examples of how to handle these themes in documents that handle greenstructure planning from the municipalities of Göteborg, Strängnäs, Eskilstuna, Malmö, Lund, Västerås and Uppsala.

New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.

It´s important when you are about to build a new stable or just increasing your production that you choose the right housing system and that it fits your own farm. In this study I have put together facts about different housing system for fattening bulls in order to get a clearer picture of witch system is the most suitable for my own farm depending on the conditions I have. The background of this work is my own interest for breeding bulls and I will hopefully increase my own production. Due to this I wanted to learn more and increase my knowledge about different housing systems. Through a literature study I have found out the facts about the housing systems I find suitable for housing bulls.

TFT (Thought Field Therapy) och EFT (Emotional Freedom Techniques) är två energipsykologiska metoder som använts vid ångestproblematik. Energipsykologi är ett samlingsnamn för metoder med influenser från bland annat traditionell kinesisk medicin. TFT och EFT har diskuterats som ett komplement till vedertagen behandling vid traumatisering. Föreliggande uppsats syftade till att undersöka området energipsykologi och belysa TFT och EFT för traumabehandling. Datainsamling genomfördes i två steg genom en litteratur- och intervjustudie, som jämfördes med varandra.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

Wooden joist slabs is a common type of floor in residential buildings. Higher demand and production of residential buildings increases the possibilities of profiting by optimizing the system of joists in a variety of areas. Spring and deflection is something most people can relate to since it?s not that uncommon to hear furniture rattle when you walk over a wooden floor. To remove the presence of those kinds of vibrations the system of joists have to be made stiffer than the standard joist construction that is used in today?s constructions.

Hur kan studenter spara pengar på sitt boende? Enligt SSCO är bostaden den tyngsta utgiftsposten för studenter. Genom att kombinera vandrarhem med studentbostäder kan man göra det möjligt för studenter att spara pengar på sitt boende då de t ex åker till sin hemstad - över helg liksom sommar. Genom att lägga till studieytor och kontorshotell skapas en flexibel byggnad som ger och tar av varandras ytor beroende på tid, dag och månad.Synen på material har också spelat stor del i projektet. Vad händer med befintligt material då en byggnad ska transformeras? .

Through the entry of web 2.0 the technologies behind web development has changed dramatically. Asynchronous JavaScript and XML (AJAX) is the umbrella term for different techniques that make it possible to build rich and interactive user interfaces in today?s web browsers. Service Oriented Architecture (SOA) describes how common services can be bundled and published so they can be consumed by different systems.The company SYSteam Evolution AB, which has requested this project, wanted a web application that shows a graphical activity chart in order to easier view ongoing projects. The goal for this project is to develop a demo platform that shows how AJAX and SOA can be used to create flexible and reusable applications.
