Att skapa ett informationssystem ? en holistisk ansats
This thesis aims to discuss how an information system and its users may adapt to each other. The main discussion is how to create an information system that is adaptable without losing its organising properties. The thesis uses a holistic approach to the topic and the areas being dealt with are information architecture, interactive information retrieval and information searching. The practical work consisted of constructing a database for Autoliv?s Research and Development branch.
Kvalitetsarbete i grotskotning
This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.
Controllerns roll i utvecklingsprojekt : Fallstudie hos Volvo CE och Scania CV
In order for companies to be competitive they perform different types of development projects. Due to globalization a greater focus is added on costs, not least on costs in development projects. Project controllers are involved in development projects in order to review the financial aspects. The authors have examined the role that project controllers hold in respect of two Swedish manufacturers, Volvo CE and Scania CV. The investigation has revolved around three main issues where the authors conducted interviews with controllers that do not work in development projects and project controllers in development projects. The goal of the interviews was to gain a greater understanding of the role of project controllers, how this role will differ from those that do not work in development projects and the difficulties faced by project controllers.
Analys av fiskerättsförhållandena i Stockholms skärgård i relation till känsliga områden samt fysisk störning
This work is a GIS study of fishing rights distribution between different categories of ownersand properties in the Stockholm Archipelago. The purpose was to create basic data used toestablish fishing laws and restrictions within the Stockholm County.Stockholm?s archipelago consists of a unique environment and is the natural life andreproduction environment for ? of Sweden?s reproducing fish species. The increasingpressure from fishing, tourism and weekend population increases the need for an efficientfishing administration to prevent impoverishment and to ensure the biological diversity inSwedish fishing waters. There is an increasing need to review fishing administrationmethodologies, as well as studying the categories of ownership and properties located insensitive areas and areas influenced by physical disturbances in order to establish effectivelaws and restrictions.The Swedish fishing rights for an area are currently not connected to the ownership of theproperty to which it belongs.
Konvertering från direktverkande el i kommersiella lokaler : Ekonomisk och hållbar utveckling
Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.
Utvärdering av kalkstens egenskaper med laboratorie- och fältmetoder.
A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.
Digital Signage - Infokiosk; Utforma för uppmärksamhet och interaktion
The purpose of this thesis is to investigate how Digital Signage systems such as public info kiosks can be designed to better fulfill its main use; to enlighten, encourage and influence the public with information. The challenges presented from earlier studies shows that the public interests and goals, together with proper and relevant content displayed in info kiosks have impact on the attention the public have towards public displays. Qualitative methods such as interviews, usability testing and observations were conducted to further examine how a public info kiosk can be designed to draw attention and grow interest amongst students at K3, Malmo University. Usability testing were used on the digital prototypes that were developed to ensure that the gestural user interface meet the requirements of a proper interaction from the users. Important insights were made concerning; the attention and interest to relevant content, the aspects of the gestural user interface along with the placement of the info kiosk in terms of context.

Vägen till god användbarhet : En fallstudie inom informationsarkitektur med fokus på ett informations- och filhanteringssystem
Since Internet has become a more important and more certain source of information the user require greater and more demands than ever before on the layout and function of different web pages. When search engines gives us the opportunity to millions of hits in just a fraction of a second it?s essential to optimize the structure and architecture, which forms the foundations of all the content. In a time when a company?s digital footprint plays an important role for the costumer and the transmitter it?s of utmost importance to have a steady, well-structured foundation to build new platforms of information on.But how do you manage to build a good foundation? Some of the most important key elements in Information architecture are Organizing, Navigation, Search and Labeling.The aim of this study was to create guidelines for a user-friendlier interface, by analyzing the principals and gathered data.

Analysmetoder för rörsystem
The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.This has been evaluated by creating a detailed Finite Element model of a pipe that is being bent. Then the differences compared to a bent tube in a virgin state, so called Elbow elements and an analytical in-house program have been evaluated. The virgin state refers to a model of a pipe that is bent from the beginning, thus having a homogeneous thickness and not containing any plastic hardening. The Elbow element is a calculationally cheap element, specially developed for accurate calculations of pipe bends in an initially virgin state.The goal with the thesis work is to get a better picture of what happens to a pipe as it is being bent, how this affects the mechanical properties and to evaluate the possibility to develop an easy method for taking these effects into account when using the Elbow element.This report describes the layout of the work and how the detailed FE-model has been constructed.
Webbsystem för matprisjämförelser
This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.

Områdesinbäddning för ODE
This paper gives an introduction to the theory of minimal surfaces. It is in- tended for undergraduate students with some basic knowledge of differential geometry and complex analysis.After defining the concept of minimal surface and giving a brief histo- rical survey, we look at some well-known minimal surfaces and a few of their characteristic properties. The connection between minimal surfaces and harmonic functions is discussed and the Weierstrass-Enneper represen- tation formulas are introduced. We also present Bjo?rling?s problem and give some examples. .
