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.

Cloud computing is a new buzzword within the IT-industry, and introduces a whole new way of working with IT. The technique delivers web based services, which results in that the user no longer needs to install an application locally on a computer. Since the application no longer needs to run on a local entity, but in a datacenter located on a service provider, the users no longer need any specific hardware more than a computer with an internet connection. Cloud computing also offers IT-infrastructure and development environments as services, these three service types is better known as cloud services. Through the usage of different types of cloud services, the need for maintenance and hardware is significantly reduced.

The aim of this master?s thesis is to examine how managers in some public libraries are using performance measurements and to what extent decision making is based on the results. The main questions posed are:??What performance measurements and indicators are used in the libraries examined???What is the attitude towards performance measurements among library managers???How and to what extent are performance measurements and indicators used in the process of decision making???What improvement would library managers wish regarding the development of performance measurements in public libraries?The theory is based on a model of evaluation of the public sector in addition to general steps of evaluation of quality and performance measurement results. The investigation is based on qualitative interviews with seven managers of public libraries in Sweden.

Change is a natural state for both people and institutions, but as the surrounding world moves faster it becomes important to quickly be able to adjust to new conditions. Customers? force of negotiation increases as the global competition grows. One factor that becomes more vital to customers is the amount of quality standard a company can offer them. Several factors are essential if a work of change will be considered a successful investment, where the change can be perceived in both a positive and negative way for an employee.

Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements. There is a therapy model, called solution-focused therapy, used in family and individual therapy. The model focuses on solutions for the future instead of problems in the past.

This master thesis is made of two parts. The first part concerns the method and results ofdesigning a motion control system for a piece of research-equipment called BIRGIT. Theequipment is made to be used for research on eyemovements. In the second part, a computermodel of a part of the balance organ in the inner-ear is developed. The work has been done atthe Bernadotte laboratory at S:t Erik Eye Hospital.The equipment the control system is made for is a so-called rotationchair.

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.

The use of mobile devices has during the last years expanded and on the market you can see a huge amount of applications. The development of mobile applications differs from traditional systems development since mobility infers that mobile applications can be used in different technological and social contexts. Although previous research has recognized that mobility can present mobile application developers with certain challenges, empirical studies of how problems arise and how they can be handled has thus far been limited. In this study we focused on the requirements engineering process from a development view with the purpose of finding challenges emerging in the development process. The study is based on a qualitative case study that employed semi-structured interviews with both project managers and system developers active in the requirements process.

 We have chosen to write our thesis within a transport company. The work was carried out at DHL activities in Uppsala. DHL is one of the leading transport companies worldwide. Our interest lies in more efficient and advanced transportation and terminals, as globalization and new trends require effective solutions.The aim of our work is to explain the need for information technology applications in road haulage and associated terminal operations. Furthermore, we analyses terminal and applied information technology.

For a school library to function as a support for the students? development of their academic abilities, it must provide material satisfying their needs as well as the needs of the teachers. The school library should assist the students in their research endeavours, as well as inspire reading for pleasure. In order to do this it is imperative that the school library actively develops the existing collection and continually strives to meet the needs of its users. The aim of this Master?s thesis is to describe and reflect upon how a particular school library works with collection development.

In Sweden the residential and commercial sector is a major user of energy, why the Swedish government has set a specific goal to half the energy usage in buildings by 2050, compared to 1995. The Swedish Energy Agency has therefore started the campaign ?Halvera Mera? to encourage demonstration projects that will show how to renovate in an energy efficient way, and in doing so prove that it is possible to reduce a building?s energy usage by half and still make a profit. These projects are intended to serve as good examples and give inspiration to residential owners to perform energy efficient renovations. To make sure that these projects serve their purpose, it is important to know what will inspire and what will impede a residential owner to invest in energy efficiency improvements.

This study aims to explore purposes of daily workshops for persons with disabilities. The method used was qualitative interviews. An inductive research strategy was used. Half-structured interviews with six managers of daily workshops were carried out, wherein they expressed their intentions with the daily workshops and the reasons for people to participate. The interviews were analysed with Antonovsky´s salutogenetic perspective, in which Sense of Coherence, SOC is a main concept, and with the normalisation principle.

Why participate? Many studies focus on explaning non-participation in politics. The political parties are loosing members and the particiaption of young people are given extra attention. This thesis is about young people who do participate in party politics. The question is how they experience their participation and how they feel that they can have a politcal influence by being a member of the youth section of a political party.

AbstractSAAB has for a long time used user controlled pilot models in ARES. ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.

Stress is something that has increased in recent decades among adolescents. Several reports indicate that young people today are more stressed because of the many demands they wear. They should be good in school, achievement expectations, get an education or job, make choices and think about their future. The purpose of our essay is that we want to explore and gain an understanding of how young people in the third grade in high school looks to stress. To conduct this study, we used a qualitative approach, by doing interviews with 10 high school students attending third grade at Västerviks gymnasium. The result we got out of the interviews was that young people experience stress differently, depending on their different as individuals. We found that there are different causes of stress, such as school, media, friends, demands from various quarters and choosing education.The interviews showed that some kind of stress was possible to handle for the adolescents, for instance by making schedule. Some stress from society was, on the other hand, more difficult to avoid..
