During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

My objective for this project was to create a short but thrilling 2D-animation intended as promotion for an online comic book. The purpose of the project was to learn more about animation and graphics, to further my artistic skills and to learn how to work in Adobe After Effects. I also wanted to learn more about scheduling, project methods and how to handle stress. During the ten weeks of the project I have created the story, the storyboard, the character design, the backgrounds and the animation. The voice over was recorded with the help of a fellow student who also made the music and the sound effects.

AimThe purpose of this study is to, from a perspective of a PE teacher, look at how teachers of physical education in elementary school designs and assesses the teaching of swimming. The issues underlying the study are as follows:Which elements are included in the swimming education and how do teachers work with these operations?What does the PE teachers classify as swimming ability and what do teachers experience as obstacles for the students development of swimming ability?How do the PE teachers interpret the knowledge requirement in Lgr 11?MethodThe study is based on six interviews of qualitative nature, with PE teachers from various municipalities in the region of Mälardalen.ResultsThe result yielded by the study is that the swimming classes can take different forms depending on whom the teacher is. Common to all the teachers in the study is that they teach emergency management and lifesaving. When it later comes to teaching how to swim and practice, the teachers who teach in the younger age groups work more concentrated and continuously with swimming, while the teachers who work with the older age groups just checks whether students can swim or not.

Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.

With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.

Based on laboratory studies with lysimeters, the concentrations of dissolved reactive phosphorus(DRP) and particulate phosphorus, which is the main part of other P (OVRP), has been studied inpercolating water. The experiment was conducted through irrigation of small soil columnscontaining clay topsoil from an experimental field in Västergötland. Three rain simulations wereconsecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3mg·Lclearly related to the phosphorus concentration in the soil, measured in a soil extract ofammonium lactate (P-AL). Concentrations of OVRP were relatively low and ranged between0.12 and 0.16 mg·Lwas not proven and the experiment may reflect how a relatively slow percolation of water mayrelease DRP.

This study was conducted at the City Abattoir in Kampala, Uganda to evaluate the cleaning process, with focus on bacterial pathogens, in a pilot scale integrated bioprocess. This consisted of four steps: anaerobic sequencing batch reactors; aerobic/anoxic sequencing batch reactors; a high performance temperature controlled methanogenesis digester and a constructed wetland. The objective was to determine if this type of cleaning process could be used to clean wastewater from abattoirs in a satisfactory way. The indicator organisms for faecal contamination, Escherichia coli and Enterococcus spp. were used to investigate in what numbers bacteria could be found in the untreated wastewater and how much that was reduced in the different steps of the cleaning process. The water was analysed for Salmonella to see if human pathogens could be found and could survive the different steps of the treatment process.

To investigate if the student?s school centeent, and that planning of the school lunch is done from a health perspective. Qualitative research approach was used, including both interviews and observations, to view the purpose. Evidence was collected using a participating observer, semi constructed questions and structured observation. To focus on specific parts in the material, a directed content analysis was used. One large and one smaller school participated in the study.

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.

För att Securitas AB skall kunna behålla sin position i Norrköping Flygplats är det viktigt att de effektiviserar sin bemanning och scheman. Detta krävs för att kunna uppnå kostnadsreduceringar som skall i sin tur ge dem konkurrensfördelar för att behålla sin position vid årliga upphandlingar som sker mellan kommun och flygplats. För att effektivisera sin bemanning och scheman skall teoretiska delar användas för att styra grupper och verksamheten bättre, teoretiska delarna är i form av schemaläggningsprinciper.Vid en effektivisering av verksamheten skall en optimeringsmodell användas med flera funktioner som möjliggör en heltäckande optimeringslösning för att generera den mest kostnadseffektivaste bemanningen för schemaläggningen. Ett tekniskt system som ett informationssystem skall även strukturera Securitas arbete effektivare med en bättre bokföring över de anställda samt underlätta tillämpningen av ett standardiserat arbetssätt. Vikten av ett standardiserat arbetssätt behandlas mycket inom LEAN-filosofin och anses viktig i detta fall för att få de teoretiska delarna och informationssystemet att fungera ihop.

In the profession of architects there is an element called architectural competitions, where several architects compete in submitting the best solution for a certain task. In this master?s thesis I am studying the competitor?s perspective of an international architectural competition, while at the same time gaining experiences for my future career as a landscape architect. The aim of this thesis is to through an introspection of my own process examine a competitors view of the international architectural competition and how to approach the difficulties concerning international competitions. Through that I hope obtain experience about the international competition as part of the profession of landscape architects and other involved professions. To examine a competitor?s reflection of an international competition, I entered and competed in LE:NOTRE Student Competition, a competition for students where the task was to develop 25 kilometers of complex urban periphery along a chain of natural and artificial lakes in Bucharest, Romania.
