Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

The most common method for identifying merchandise in the commerce is by barcodes. Symbian OS is an advanced operating system aimed at cell phones and the most commonly used in smart phones. Opportunities to a full range of new services are given through barcode recognition in a Symbian OS based device. Therefore the purpose of this degree project was to create an application which would contribute to a future solution aimed at shopping where the cell phone constitutes a reader of items? identification numbers.

This thesis examines the problems related to IT in the Swedish healthcare system, specifically the drug searching part of the electronic healthcare systems used in Sweden. The question formulation is divided into two questions: What parameters and functions are of greatest importance when performing a search on drugs, and how should these be presented in a graphical user interface? Thus the purpose is to answer these questions through developing a design concept, in the form of a prototype, which describes how a drug search can be carried out.The entry point is a central quality checked drug database that is managed and owned by Swedish county councils and regions. The problem is attacked through user-centered methods where interviews of physicians and developers, in conjunction with observations, are used to give an overview of the problem area as well as to specify a requirements specification for the prototype that this thesis aims to develop. The thesis result is a requirements specification in combination with a prototype that exemplifies how drug searching can be performed, the prototype is based the requirements gathered from the interviews with the user group of physicians..

The aim of this thesis is to study a number of standards and theories, from the two research areas human-computer interaction and psychology, about how a graphical user interface (GUI) should be composed in order to facilitate interaction between humans and computers. Special emphasis is put on how the GUI should take into consideration the strengths and limitations of human cognition and perception. A study of three web catalogues shows how these theories appear when concretised. The following questions are answered in this thesis:What guidelines and styleguides can be found that specify the design of a user-friendly GUI?How do a few library catalogues on the web match a selection of these design principles?The guidelines are extracted from literature concerning human-computer interaction, psychology, automated library systems and web design.

This essay studies the practice of both the political and the administrative leadership at the municipal level from the point of view of the politicians and the chief officers leadership role, and the relationship between politicians and administrators. I discuss and analyse how politicians and senior officials practice leadership, differences or similarities and if their practice of leadership raises any challenges in a democratic framework at the municipal level. I conducted interviews with the municipal political leader and the head of administration at the municipal level in Karlshamn and Sölvesborg. In the analysis I discuss communication as a leadership process which highlights ?enabling elements? and potentials of the leadership process.

Trådgnistning (på engelska Wire Electrical Discharge Machining eller WEDM) är en termiskbearbetningsprocess för att med en trådelektrod skära i elektriskt ledande material. Metoden har teoretiskt sett många fördelar och relativt få nackdelar. Intervjuer i studien visar att trots detta så undviker flera industriföretag om möjligt denna process. Syftet med studien är att utifrån de teoretiska fördelarna som anges i litteraturen undersöka vad företag i Sverige anser vara de mest relevanta praktiska fördelarna med trådgnistning som bearbetningsprocess. En internetbaserad enkät har skickats ut och besvarats av 20 industriföretag runtom i Sverige.

This study is an evaluation of the runtime watch function in a OEE software, knownas ProTAK. OEE stands for Overall Equipment Effectiveness, it?s a way to measurethe factories process efficiency. The runtimewatch function allows the user to setup and monitor certain critical objects that are of importance for the pulp and paper process at the mill. The data from the runtimewatch can be correlated towards the suppliers specification for the components.

Liquid Media är ett litet företag lokaliserat I Stockholm, Sverige. Dom har en rik historia med flera spel produktioner i sin merit lista. Jag fick som uppgift att skapa ett flertal visuella föremål till några av deras mindre projekt. Jag har här sammanfattat mitt arbete om hur jag gick till väga för att lyckas med detta. Mitt arbete på Liquid Media involverade flera olika delar av spelkonst produktion. Liquid behövde olika kläd- och hudtexturer till deras spel karaktärer, dom behövde modeller för ett andra spel projekt och dom behövde även omorganiserade uv-mappar till några klädtexturer i förebyggande syfte så att användaren i framtiden ska kunna byta kläder på rätt sätt. För att klara av dom olika uppdragen som jag åtog mig bestämde jag mig för att använda olika program för olika ändamål.

In this project the task has been to develop a product that will facilitate an operation for personnel working in a sterilization center. The operation is to steer the front of a loading trolley into the chamber of an autoclave, a so-called docking. The moment is complicated because the margins to deviate from ideal docking position and still succeed, is very small.The principal Getinge's desire was that the product could be retrofitted at the customers on their existing systems. One of the demands was that the product should fit two types of trolleys, one with a adjustable working height and one with a fixed working height. Getinge is supposed to purchase the system from a subcontractor who shall manufacture it and the requirement from Getinge is that the cost of purchase mustn't exceed SEK 500Initially principles, solving the problem was developed.

Examensarbetet är utfört hos Aaro Systems AB, som säljer ett datasystem som hanterar bokslut, redovisning och konsolidering av ekonomisk data för koncerner. En del av detta system är ett web-gränssnitt där man kan generera och manipulera ekonomiska rapporter. Min uppgift var till en början att undersöka hur detta gränssnitt kunde anpassas för att visas på mobila enheter. Det visade sig dock fungera bättre än väntat utan några störremodifikationer så efter en vecka omdefinierade vi min uppgift till att utveckla ett övervakningssystem för kundernas applikationsservrar. Varje kund hos Aaro kör sin egen applikationsserver på plats.

One step towards a more sustainable energy system is to create a more flexible electrical grid, where increased demand response among electricity consumers can play an important role. A distribution grid owner can encourage their customers to use electricity more evenly distributed during the day by introducing different types of grid fees such as time-differentiated power tariffs. In this master thesis, the theoretical economic impact of a flattened load profile for a distribution grid owner is investigated. Different factors that impact the distribution grid owner?s economy are identified and two are chosen to be quantified; losses in the grid and the fee to the feeding grid.

The study part consists of examining and comparing different data acquisition systems for testing of different circuit boards, taking into account the modularity, real-time applications, mobility, environmental, interface hardware and software, to be able to define a general module-based data acquisition system in both hardware and software that enables for future developments.The programming part consists of getting started with Visual Studio, which integrates the Measurement Studio for C#. NET. Measurement Studio includes classes and user controls for testing and measuring and offers tools for acquisition, analysis and presentation of real world data.

The purpose of this masters thesis is to study two subject gate-ways within the field of Swedish higher education and academic research, concerning structuring and selection of Internet resources to facilitate information retrieval for their target groups, and also to study two co-operation projects in the same field, one national and one European, to see how the co-operation is being carried through and how the gateways in the projects can serve from a wider perspective. The gateways, AGORA and NOVAGate, are being studied mainly by their Web sites and two e-mail interviews with persons responsible for the gateways. Facts about the national project are principally based on an interview with BIBSAM. The European Renardus is being studied out of articles and information on the Web site. From the results of the study it is being clear that the purpose of the gateways is to make a quality-selection of information accessible via the Internet and thereby facilitate for their target groups to find usable information.

Inadequate data quality has a negative effect for organizations, however utilization of modern technology and data analysis may shape new values for organizations. Our research has found that the quality of information in field reports for error reporting varies significantly. In many cases, the information in the field reports are deficient in such way that the field report need additional information from the sender, thus risking prolonging lead times in the error reporting process. More efficient use of information has become possible with today?s technology.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.
