The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems. The aim of this study is to: ? investigate the work pattern of the production managers when using the information system to plan the harvesting operation; ? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system; ? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern; ? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion. The conclusions of the study were: ? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning; ? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information; ? the computer systems are however divided in many subsystems.

Vid design av IT-system krävs en förhållning till de specifika egenskaper som finns i den miljösystemet är tänkt att användas. Även om användningen ser liknande ut krävs en detaljeradanalys av det specifika sammanhanget för att få en djupare förståelse för hur det verkligaanvändningsområdet ser ut. Det har visats sig uppkomma användbarhetsrelaterade problem vidförflyttning av ett system från en stationär miljö till en mobil miljö. Rapporten har undersöktvilka utmaningar som uppkommer när ett system flyttas från en mobil miljö till en annan snarlikmobil miljö och tar sin utgångspunkt i Ecodriving-lösningar för tunga fordon. En kvalitativundersökning genomfördes för att undersöka och identifiera de utmaningar som uppkom.Analyserat material låg till grund för framtagningen av en prototyp.

The purpose of this thesis was to examine if there where fallacies in the design solutions for the business system IFS Applications from a user perspective, and if so, correct these from a cognitive science approach.Data collection consisted of three main portions. These where; workshop, individual interviews and observations. The collected data was analyzed and resulted in identification of two main areas in the application that where found lacking.The result of the study showed that the usability for processing large amounts of data and the lack of customization where the main flaws in the application. Two low fidelity prototypes where created with the purpose of rectifying the underlying flawed design solutions that where identified from the collected data..

The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

This paper describes the evolutionary development of an information system for a small company. The company performs overhaul of forklifts and cleaning machines. The company has already an information system that handles the reports from these overhauls but it needs a supplementary tool that assist the chief planner to plan forthcoming overhauls.It should be able to display coming overhauls in a timetable and eventually print them, either to a PDF file or to a document. The timetables this function produces will help the chief planner and the assemblers to get a good overview of their day-to-day work.The tool needs to be intelligent in that way that it takes into consideration were in the country different assignments will be performed. So that time consuming travels over great distances can be avoided.

This thesis presents an adaptive tuning system that can be described as a dynamic Just Intonation tuning system, being compatible with equally tempered instruments. The tuning system is called Hermode Tuning (HMT) and the tuning used as comparison for evaluation is the standardized western tuning, the equal tempered tuning. This study investigates preferences for these two musical tuning systems, depending on whether the tunings are presented on a piano or with woodwind instruments. A listening test was done with students at the Falun Conservatory of Music, including both a vertical listening (intervalls) and a horizontal listening (cadenses and musical compositions) of Hermode tuned musical material. Overall the results showed no significant preferences for either tuning system irrespectively of what instrument it was presented with.

In a complex and turbulent world, several companies begin to realize the value of information as a strategic resource and try to find strategies to manage this. This master thesis aims to describe the information management at Axis Communications AB. Axis is a fast growing company and due to this they have not been able to manage the flow of information whitin the company. To find out how the information was managed at this time we made a survey and employee interviews at three Axis business units. By analyzing the surveys and interviews we found several problems.

 Extra high requirements are made on all systems in health care that they are functional and usable,´something, however, that is not always the case. At Emergency Admissions at Sahlgrenska University´Hospital many systems are in use at the same time and it happens that much overhead is caused by having to fill in the same information in different places. In addition, data that is gathered is to a large extent saved in free text format, which means that it cannot be used in a larger context such as research, quality control or for decision support. Data is saved in the patient file only for the treatment process of the individual patient.A data collecting system with decision support functionality could be a first step towards reducing Emergency Admissions? costs and patients? waiting times by providing a structured method of data collection.

This paper is about transferring a feeling from a physical place to the Internet. The paper explores methods on how this transfer is done. Websites have a tendency to not portray the company behind it in a correct way. For companies with a distinct esthetic and work hard on their image and brand it is important that this hard work is portrayed correctly in every aspect. The problems this paper explores are: the importance of personas in a design process, methods of transferring a feeling from a physical place with design and how this can be tested, and using open-source content management systems in creating usable websites.

I studien, vilken omfattade 177 svenskfödda studenter, utvecklades och kontrollerades enegenkonstruerad enkät: SAPS. Även könsskillnader i fördomar mot okända personers etnicitetoch kön samt könsskillnader i Social Dominance Orientation (SDO) undersöktes. Fördomarmättes med SAPS och SDO mättes med en svensk översättning av SDO scale (Pratto et al.,1994). SDO scale användes också som validitetskontroll av SAPS. Statistisk prövning medSpearmans Rho visade på en negativ korrelation mellan SAPS och SDO scale.

As a designer, I find myself daily being confronted with choices which eventually can be summarizedas how we experience something. What?s the function, feeling, what colors should there be, shapes,materials, etc. Different parts will be combined to create an entirety. The only question is why we areaffected so differently by the same entirety.In this project I have examined how the relationship between a space and a product affects ourperception of a coherensy and what it is that makes us experience it so differently.I wanted to find a way to methodically explore the importance of the coherency for the experience ofa product and a space in relation to each other, in order to produce a material that can form the basisfor further work on the spatial context.I?ve looked into the psycological term central coherence and formed a scale that shows the humanabilities to perceive a context in various psychological conditions.

This thesis is carried out at Portsystem 2000 AB who manufactures and markets industrial doors and docking systems. The background to this thesis is that the company?s management considers that their follow-up process of cost accounts is not fully functioning.The aim with this report is to investigate and describe the present procedure of the follow-up process concerning the time of operations and come up with suggestions for improvements. This thesis is performed within the range of the following areas: Information systems, quality, processes and cost calculation. The main method we used were semi structured interviews with a fairly opened framework.

Two post milkning teat dips (PMTD´s) were compared in an automatic milking system at Kungsängen Research Farm, owned by SLU (Swedish University of Agriculture) in Uppsala. In the experiment an evaluation system was used where teat condition regarding skin and teat ends was graded according to a scale where 1 was the best score and 5 the worst. The evaluation period was almost six months in total devided into four minor experimental periods. The technician scoring the teats did not know which PMTD that was currently used. Statistical analysis showed a significant difference between the two PMTD´s regarding teat skin condition, but not regarding teat ends.

The purpose of this study is to examine whether personality traits, self-esteem, performance-based self-esteem and demographic data relate to, and can explain the variation in psychological ill-health among students at Lund University. A questionnaire was distributed to students attending the Psychology program, Bio-technology program, Theologian program and Law program. There were 247 respondents to the questionnaire, mainly attending their second or third semester. General Health Questionnaire (GHQ-12), Rosenberg's Self- Esteem scale, Hallstens scale measuring performance-based self-esteem, questions relating to demographic data and a short version of the personality inventory scale Big Five were included in the questionnaire. Positive correlations were found between psychological ill-health and the variables neuroticism and performance-based self-esteem.
