Högskolebibliotekariers informationssökning : en studie i hur högskolebibliotekarier söker information till sig själva och för andra
The purpose of this thesis is to examine how academic librarians seek information for themselves and for others, and what differences exist. The terms self-generated and imposed information seeking is used to describe the two different types of information seeking. Step 2 ? define and understand the problem, step 3 ? choose a search system and step 4 ? formulate a query of Marchionini?s information-seeking model forms the basis of the theoretical framework, which is supplemented with Soergel and Katz. Qualitative interviews with eight academic librarians were conducted and analyzed in order to gather empirical facts.

Intranät : en kunskapskälla i arbetet?
The ambition with this study is to look into and create an understanding for how an intranet can work as a support system in work processes in capacity as a source of knowledge. We want to enhance the understanding for which kind of knowledge that can be coded in and transmitted by an intranet, and which that is lost in this process. We also want to clarify what it takes to get this knowledge, in collaboration with the intranet, to support the work in an organization. It is a qualitative case study at a Swedish bank. It consisted of semi standardized, half structured interviews with five people in one of the bank?s local offices.
Enskild väg till Tolleredsskog
This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..
Design av verklighetsanknuten matematikundervisning
The aim of this study was to design short interventions based on the literature study, which will change the pupils? posture on mathematics and connections between problem-solving in mathematics and everyday life. An experimental group of 17 pupils in fifth grade participated in the study and were educated in everyday mathematics 20 minutes a day during four weeks. The intervention was measured in a pre- and after questionnaire, in order to control the design and discover possible changes in the pupils? posture on mathematics and connections between problems and everyday life.
Designerrollen i en webbdesignprocess
This study investigates if, and in that case, how design theory is applied in practice in the web development field. Prior research has focused on methods used in the web development field. We wanted to study the designers role in a web design process by comparing existing designer roles with design theory literature. We did qualitative interviews with two practitioners at two different communication agencies in northern Sweden. Based on our qualitative data and literature review we have concluded that a designer has to devote a lot of energy on requirements engineering in order to develop a clear understanding of the design situation..

Implementering av mjukvarubaserat PLC-system för reglering av magnetiseringen av en synkrongenerator
In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..
Verktyg för utveckling av terrängparker inom skidanläggningar. : Shaper
Today we can create digital 3D models which can be realised almost instantly through production methods such as 3D printing and computer controlled milling.What if this same technology could be applied to the development and construction of terrain parks?With snow as the material tools could be developed using similar principles to design and sculpt the surface, only on a larger scale.How would terrain park designers adapt their process to use this new technology? In this Industrial design thesis I explore how the ideas of the terrain park designer can be expressed through such a system with focus on the designers knowledge and skill without the need to learn complicated 3D programs.Sketch, create, ride. .
"Ettan" som kom först : En kvantitativ innehållsanalys av hur en studenttidnings förstasida förändrats genom tiderna
The aim was to explore how the first page of a student newspaper has been changed over time since it was founded in the 1960´s.This thesis explores how the front page of the student newspaper Lösnummer has been changed since it was founded in 1966. It concerns the location and frequency of elements and it is based on theories of layout, the first page and visual communicationIn addition, the thesis develops a new kind of method for determining the location of elements on the type area. The method is based on the hexadecimal number system. It is formed as a grid which is placed on the first page to determine the location of the elements.It concludes that the frequency of elements had its peak during the 1970´s and has ever since decreased gradually. Image placement has gone from being scattered all over the front page to be centered and increase in size. .
Funktionella krav på metadata: En undersökning av Dublin Cores överensstämmelse med FRBR
The purpose of this master thesis is to examine how Dublin Core corresponds to the findings in the IFLA report Functional requirements for bibliographic records FRBR, and what consequences this correspondence has on the usability of Dublin Core as a bibliographic standard. While the study describes the conceptual model of FRBR and the entities work, expression, manifestation and item, its main focus is the mapping of attributes and relationships to the user tasks defined, namely to find, identify, select and obtain entities. The study makes a comparison between data that FRBR rates as highly important for any user task, and the elements defined in DCMI Metadata Terms. The outcome of the comparison is then analyzed as to how it affects Dublin Core's possibilities to assist in the different user tasks, and common problems are discussed. The results show that problems in expressing attributes and relationships through Dublin Core elements concern all of the four user tasks.

Effektiva återkopplingsverktyg för elanvändning : En studie som syftar till att identifiera utvecklingsmöjligheter för att uppnå ett mer hållbart energisystem år 2030
Feedback tools support electricity users within the Swedish residential sector to increase their knowledge of electricity and the electricity market as well as to become more aware of their electricity consumption, which in turn encourages a reduction and an increased flexibility of electricity use. The primary aim of this study is to identify and analyse how existing feedback tools can be improved, to ensure that they contribute efficiently to the achievement of the EU objectives congruent with a more sustainable energy system in 2030, emphasizing: greenhouse gas reduction, increased energy efficiency and an increased share of renewable energy. In order to reach the primary aim of this study, existing feedback tools have been identified and mapped and interviews with feedback tools providers have been conducted. The study is limited to three research areas: the practical functions of feedback tools, available technology and the use of feedback tools.The use of more efficient feedback tools will provide an increased success rate for energy management, which includes both behavioural changes and energy efficiency. According to the results from the interviews conducted for this study, an increased use and user frequency is important to utilise the energy management potential.
