Testning är den aktivitet där man verifierar och validerar ett IT-systems krav och exekverar det i syfte att hitta fel. Testning kan utföras både manuellt och automatiserat, genom att utveckla ett system som exekverar testerna åt sig.I detta examensarbete beskriver jag hur jag designar och utvecklar en IT-artefakt som automatiskt kan exekvera tester av ett annat system..

The wide spread of the Internet and new information technologies in recent years has come to effect how libraries manage and disseminate information. Search engines like Google are widely used by people who often find the information retrieval systems of libraries to be too complicated. In 2004 Google announced plans to digitise five major library collections. Organisations representing the publishing industry and authors have since then filed lawsuits against Google claiming that Googles scanning of library books infringe the rights holders copyright. Due to Googles potential impact on libraries this thesis aims to examine how Googles digitisation project, Google Book Search, has been received in the library community.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

This Master?s thesis examines different retrieval strategies used in cross-language information retrieval (CLIR). The aim was to investigate if there were any differences between baseline queries and translated queries in retrieval effectiveness; how the retrieval effectiveness was affected by query structuring and if the results differed between different languages. The languages used in this study were Swedish, English and Finnish. 30 topics from the TrecUta collection were translated into Swedish and Finnish.

Vårt examensarbete har genomförts på företaget Electrolux Laundry Systems (ELS) logistikavdelning, Logistics Center Ljungby (LCL).  Under det senaste året har företaget haft motgångar vid ett IT/IS-projekt inom sin logistikavdelning (LCL). Uppsatsen har således syftat till att beskriva och analysera varför IT/IS-projektet har avstannat, och ej nått implementering. För att uppnå syftet har vi utgått från en, i stort sett, kvalitativ ansats där primärdata har insamlats genom metoder såsom intervjuer och deltagande observationer medan sekundärdata inhämtats i form av dokumentundersökningar och offentliga dokument. Resultatet av studien har utgjorts av deltagande observationer på fallföretagets logistikavdelning, LCL, samt intervjuer med olika verksamhetsnivåer. Detta har påvisat bristande kommunikation och direktiv samt fallföretagets brister i förstudiens utförande vad gäller förankring av projektet, planering av tid, resurser och kostnader samt formulering av krav.

The farming system is the basis of human existence through its production of provisions for man. By a continuous exchange of information, energy and material, between the ecosystems and the social systems, the farming system becomes an emergent property. The system's own properties, in the sense of farming methods, circulations and institutions, evolve through an adaptive process. Understanding this process and constantly learn from it, is the starting point for creating a sustainable development within farming systems. Thus, future farming system has to develop strategies that produce food provisions while at the same time takes into consideration the ecosystem's resilience and its integrity, but which also enables an ethical discussion. The institutions within the farming system are understood as links between the ecosystems and the social systems.

This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.

The aim of this Masters thesis is to conduct an analysis of the Swedish classification system the SAB-system from a feminist and queer theoretical perspective. The theoretical framework of the study is feminist and queer theory as well as theories from Library and Information Science, mainly classification theory. The study takes its departure from the idea of classification systems as social constructs, reflecting their time, place and society. Paul Ricoeurs critical hermeneutics is used as methodological guidance. This gives room for a critical perspective in the interpretation.

The pace of product development is increasing. It is important to keep high quality in theproducts even though the time for product development decreases. Those companies whichcan utilize previous experiences are positioned with a significant competitive advantage. ToABB Robotics it has become evident that the knowledge transfer process within the productdevelopment department is inadequate. This study was a result and an attempt to address thisunsatisfactory insight.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

The demand for district heating is expected to decrease in the future, due to competition from heat pumps and energy efficiency measures in buildings. Development of existing district heating systems is therefore necessary for district heating companies to maintain market shares. This Master?s thesis describes and investigates the heat and electricity production and profitability of a combined Organic Rankine Cycle (ORC) and heat pump that is integrated with an existing district heating system. The studied district heating system is utilizing heat from waste incineration. In Sweden waste constitute 20 % of the fuel mix used in district heating systems, and this share is expected to increase in the future.

The web has a broad affect on the global economy and can among other things be used for web based information systems (WIS). These systems have grown from being used as a market platform to support all activities in the work of an organisation of today. To survive in a turbulent competitive environment, companies must start to cooperate with their customers instead of just collaborate with them. Can an IT-consultant company use a WIS as a tool for keeping in contact with existing customers to attain this cooperation? A WIS could strengthen the relation between customer and supplier and through that have a possibility to increase the customer use since it can facilitate business processes and imply that services can be offered in a new way.

West Pokot County is located in North Western part of Kenya where the previous lifestyle was nomadic pastoralism. However, in recent years the semi-arid county has been under dramatic developments and a sedentary agro-pastoral lifestyle is now growing. This is a major change in production systems and there is a big knowledge gap especially for the livestock based agro-pastoral systems. The main objective of this study was to investigate the current situation of animal husbandry in West Pokot. Twenty farmers were interviewed in Chepareria Division, using semi-structured interviews to investigate if the use of enclosures have had any effect on animal husbandry in West Pokot and if so, how have this method affected the animal husbandry? The results of the study indicated that there is a difference in animal husbandry between farms using enclosures and farms not using enclosures.
