The purpose of this Masters thesis is to compare the scheme structure of two national classifications system, namely the Swedish SAB system and the German ASB. It has been assumed that there are no major differences between the two models of classification systems or the main classes into which documents are placed. The classification theory and subject analysis, which form the basic theory on which my research is based, are taken from Dahlberg, Langridge and Rowley. A comparison of 30 monographs classified in the SAB system Sveriges allmänna biblioteksförening and in the German ASB system Allgemeine Systematik für öffentliche Bibliotheken showed that the classification structure was primarily responsible for determining where a particular document was placed. However, despite the fact that the subject in various documents may be similar, my research will demonstrate that the structure of the two codes also depends on different interpretations of the main subject in a document.

Användningen av Internet har ökat kraftigt de senaste åren och begreppet webbportal har blivit allt vanligare. Syftet med det här arbetet är att undersöka om det är en webbportals design som är det avgörande vid valet av webbportal eller om det är innehållet och tjänsterna. Kanske är det en kombination av design och tjänster som värdesätts högst.I detta arbete utförs en heuristisk utvärdering av ett antal bostadsförvaltningsportaler för att undersöka både eventuella användbarhetsproblem samt hur väl designade portalerna är. I arbetet görs även en enkätundersökning hos ett antal utvalda hyresgäster hos AB Skövdebostäder för att undersöka inställningen till designen av företagets webbplats samt dess innehåll och tjänster.Resultatet visar att webbportalers tjänster är viktigare än designen men att designen inte är helt oviktig. Några generella slutsatser kan dock inte dras av detta arbetes undersökningar eftersom både antalet medverkande portaler och hyresgäster är allt för få..

The purpose of this essay was to compare the Swedish and the Japanese pension system and see if there were any big differences or similarities. I was looking for answers to such questions as if the systems were modelled with the problematic demographic situation in mind and also how these two countries had tried to manage the problems. Path dependency was also a central conception when I studied the reforms of the two pension systems. I mainly used literature and Internet sources in my study. There were many books on the Swedish pension system and the debates that had been going on since the 80's.

Due to a growing interest in communication in today?s society the demand for equipment that is used in communication networks increases while the competition between companies that produce this equipment grows. To meet the increasing demand and at the same time having a competitive product development many companies use some effective product design, such as the modular product design. When a modular product design is used it?s good to compare different module configurations for a certain product and to simplify these comparisons some tool can be used.

This Master Thesis is a product development project that has been carried out in cooperation withSvea Teknik AB. The company has developed an apparatus for attachment of a keel to a hull base ofa boat. The purpose for this thesis has been to compare a new concept of keel attachment incomposite material to thetraditionaldesign solution. This new keel attachment minimizes thedamages that may arise on the keel and the hull of the boat in shape of stresses impacts at grounding.Today it is a problem, relating to keel attachment on sailing boats having a fin keel or a bulbous keel.The manufacture focus on developing larger draught and shorter keel blades. The overall purpose isto increase performance of the sailing boat.The task for this thesis was to develop a concept of keel blade in composite material and investigateattachment to a sheet-shaped element.

Detta arbete består av designen av ett gränssnitt för webbplatsen whatismykidplaying.com. Designen var tänkt att ge hög användbarhet för målgruppen och testades av användare i ett think-aloud test. De fick testa och utvärdera hur väl gränssnittet fungerar och  deras feedback utvärderades och resultaten låg till grund för förslag på förändringar i gränssnittet, vissa som sedan blev implementerade. Studien har utgått från de olika stegen i en användarcentrerad utvecklingsmodell, analys - design - utvärdering - återkoppling, och en iteration har genomförts.Som utgångspunkt, för att öka användbarheten i webbplatsens gränssnitt, användes diverse regler och riktlinjer för hur användbarhet bäst kan uppnås, när designen gjordes. Hur väl dessa regler och riktlinjer fungerat tillsammans, i detta projekt och design, blev således en del i think-aloud testest utvärdering.

To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.

The study addresses the field of design as a profession and examines the views on strategic management in a design project among nine selected graphic designers. The graphic designers who participate in the study are permanently employed at design companies in Stockholm. The study has a qualitative approach and the method is based on face-to-face interviews. We have chosen to examine this subject due to the opinion among professionals that strategic management in the design industry has increased during the last decades. There is a belief that strategic management in some cases are used too extensively as a way for design companies to make more money.

In this Thesis the possibilities of designing a larger building that is very energy efficient in the sense that it would not need a conventional heating system are discussed. Solar radiation transmitted through the windows, internal heat from occupants, lamps and electric appliances inside the building and heat recovered from the ventilation system then have to be sufficient for the heating of the building. This study is of general interest since the property company, Akademiska Hus, plans to use this study as a first step in determining if this technique could be used in the future and thus be worth further investments. A building without a conventional heating system of the size investigated in this project has not yet been built.The energy needed for the heating of the building was simulated using VIP+.The conclusions from the study are that it is possible to build large buildings without any conventional heating system. This could be achieved in many different ways, for example by lowering the inside temperature or by using better windows and heat recovery system with higher efficiency.

The Mobile phone has contributed to massive changes in the way that human beings communicate with each other and is a part of society?s globalization. Opinions differ in the area of user interface where some feel that mobile phones exclude users such as senior citizens or users with an intellectual or a physical disability.Universal Design ??design for all?, is a vision that intends to bring about settings, products and services that suits as many people as possible irrespective of an individual?s needs and prospects. The criteria for ?design for all? are among other things flexibility, user friendliness, comprehensibility and a high tolerance for mistakes.The purpose of this essay was to investigate the mobile phones graphic user-interface from the theory of a universal design.

The purpose of this paper is to make an analysis of the urban Roman water system. I have chosen to work with the system as a general field, not as a case study of a single town. In my opinion such a study would not give a proper and fair view of the subject. Therefore, this paper will discuss the different parts of the system, each one for itself and name examples wherever possible, to give a wide survey of the reality of the Roman water supply system. The aim is to give the reader a clear picture of different solutions used in the time of the early Roman Empire and a good understanding of the subject..

The thesis in product development ? mechanical design includes 15 credits and was carried out during the spring of 2014 at Semcon in Eskilstuna. The task is to construct a special machine for positioning and orientation of a key blank found in six different shapes, the construction is a part of a larger machine for encoding the key blank where a pick- and-place device or robot pick up the key blank and deliver it further in the process. The entire construction is designed for ASSA OEM Gothenburg.In order to accomplish the project the first step was to analyze the existing solutions to similar problems on the market in a current situation analysis to create an understanding of the problem. This was followed by a flow analysis and a functional analysis to get a deeper understanding of the problem and structuring the machine's process flow and its features.

An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar panels. During the work process, a prototype plant has been built to compare our theory with the practical results and with our designed sizing tool. The work has rendered in knowledge that will be used to build a sun module that can be easily connect to the existing heat pump system. The existing heat pump, our test plant, has been supplemented by an advanced storage tank used to allow different operating modes.

Tillverkande företag har under de senaste åren ställts inför en förändrad marknadssituation, vilket innebär att de fått förändra sitt arbetssätt från en produktionsorienterad syn till en kundorienterad syn. Den kundorienterade synen innebär att företag snabbt måste kunna ställa om sin produktion för att tillfredsställa kundens behov.MPS-system (Material- och ProduktionsStyrningssystem) är mycket effektiva hjälpmedel vid snabba beslut och omplaneringar, de ger dessutom möjlighet att ge kunder direkt besked om orderstatus. MPS-system tenderar att bli stora och komplexa, de har kontaktytor mot nästan alla delar i företagen.Många företag idag köper MPS-system. Stora företag byter gamla föråldrade system och allt fler små och medelstora företag inför MPS-system. Kommande milleniumskiftet är också en orsak till att flera företag byter sina MPS-system idag.Med detta väcktes intresset för att undersöka om företag som investerar i dyra MPS-system verkligen får ut det de förväntar sig av dem.

The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.
