Vindfällning i naturliga och skapade bryn och kanter :
The aim of this work was to study if the edge of the forest is more resistant to heavy winds than the trees located further in from the edge, and how this edge effect changes between different types of tree species and site types.
The data was collected from an electric power line going from the north to the south of
Sweden. The mean value of the clearcutted area around the power line was 120 meters. The
main direction of the storm in January 2005 was west-southwest and thus the power line was a perfect place for gathering a large data set.
The main parameter studied was the damage frequency at the edge of the forest compared to
the trees located further in from the edge (up to 100 m from the power line). Tree species mixture, soil moisture class, soil type, topography, stand height, stand height of the stand on the other side of the power line and wind exposition was estimated.
The results showed a distinct edge effect. The edge of the forest had clearly lower damage frequency for all tree species.
A marked difference was observed between tree species and damage frequency.
Frekvens och spanningsskalning i en inbyggd mikroprocessor; for att mojliggora implementationen av schemalaggning med stod for dynamisk frekvens- och spanningsreglering for energihantering.
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.
Det är ju ändå vi som bestämmer i slutändan : En intervjuundersökning om socialarbetarens dubbla roll och makten som följer
The background of this paper is the dual role that the social worker can have, of beeing both supportive and controlling in the meeting with clients. It is also about the power the social worker can have, how they handle the power in their profession and how they remain to it in the relationship with the client. The study is qualitative and built on interviews with eight social workers that work in different areas in the social services. We have chosen to see this dual role as if the social workers have to, in their daily work, handle the roles as one authority role and one supportive role towards the client.The purpose of this study is to understand how the dual role as the social worker has in the profession, as a helper and a authority, is expressed in the work and relationship with the client. We have turned this purpose into two questions: How do social workers with authority remain to the dual roles of the profession? How do the social workers describe and understand power?We don´t want to generalize in this study, we want to give an example of the social workers own experiences about the dual role.
Har forskningen om internationella relationer någon praktisk betydelse? : En studie om idémakt i utrikespolitik
The aim of this paper is to get a deeper understanding if research about international relations has any practical meaning. The main focal point is about the importance of the scholar idea soft power, and its meaning on foreign policy actions through expressions. A quantity and quality method is used. The point of the main theory that concerns international relations takes a rationalistic perspective, and expands it to the notion that ides can have an impact on policy outcomes. Three different types of research utilization can be traced to determine in which way an idea is getting implemented.
En välfärdsstat i förändring. Friskolans intåg.
The main aim of this study is to examine the development policies of Sweden and the European Union from a postcolonial perspective. Sweden and the European Union are increasingly coming to be viewed as normative powers rather than military powers. So how does the colonial past of the western societies affect the policies of today? Are there any signs of the power structures of the past, and if so, how are these power structures manifested in the development policies of today? Since both Sweden and the European Union have come to be viewed as normative powers they are compared with each other to highlight their similarities and differences. The results of the study shows that both Sweden and the European Union can be seen as carriers of western values and interests.
Innovativt Drivpaket för Rullstol
This is a thesis for a Bachelor Degree Project, performed in the subject MechanicalEngineering. The students Roger Malmberg and Simon Hagberg have carried out adesign project on behalf of the recently established company J&D Assisting systems,located in Halmstad.The project consisted in developing J&D's first prototype of a power assisting solutionfor wheelchairs. A power assisted wheelchair combines human power, which is deliveredby the arms through the pushrims, with electrical motors, which are powered by a battery.The power assisted wheelchair is aimed at customers, who have used a regularwheelchair for a long time, but who have become weaker or just need additional powerwhen driving uphill. This kind of wheelchair will provide additional power for users,which will spare their wrists, elbow and shoulders. The product is torque sensor free andinstead it relies on the velocity.
Den fördelade makten i vardagsrummet: : En kritisk diskursanalys av PR-konsulters tal om sociala medier som kommunikationskanal.
The purpose of this study was set against the background that social media today are used as an platform for companies to communicate with their customers, as well as communicate their brand. Therefore it was interesting to examine this phenomenenon through a critical point of view and try to put light on the different forms of power that is produced on this arena.The overall aim of this study was to examine how PR-consultants talk about social media as a communication channel. The empirical data consisted of five interviews with PR-consultants on five different PR-agencies. The theoretical framework was based on a social constructional perspective and Foucault?s theory of power.
Majsensilage i Sverige
Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.

interesting. Wood chips is very popular, but also straw from grain production is on the
table. Lunds Energi AB project a combined power and heating plant in Örtofta out of
Lund. Wood chips is meant to be the main energy source, complemented by straw.
In this thesis the transportation of straw for fuel is studied.
Åtråvärda objekt : En gestaltning av troféns materialitet
This thesis revolves around my work Desirable Objects, an installation in glass and other materials, which deals with objectification based on female and animal trophies. The topics included are those that have been crucial to my working process; craft, post-colonial studies and European hierarchical dualism, where woman and nature are seen as connected, but inferior. My motivation has been to get a better understanding of underlying power structures, and put this knowledge in relation to my own work. This process has led me to make a full body casting of my own body as a method of self-exploitation, in an attempt to expose myself to a similar power perspective. By making the dualistic connection between woman and nature, I am commenting a phenomenon that in my view has resulted in a similar exploitation of both..
Handarbetets sociala rum - om emotionshantering och kollektiv identitet i handarbetsrörelsen
The purpose of this thesis is to investigate emotions and collective identity in the handicraftmovement. Which are the collective identities of craft movement, and is it possible to speak ofan over all collective identity among the handicraft people? I will also examine the emotion workboth on individual and group level.Eight qualitative interviews were conducted to achieve the aim of this thesis. Research haspreviously drawn attention to handicraft from a gender and a historical perspective but neverfrom an emotional one. The theoretical framework derives from an emotion sociologicalperspective where Collins interaction rituals, emotional energy and Hochschild?s emotionmanagement is the main theses.
Visuell presentation i slöjd : Positivt med power point?
Detta arbete undersöker problematiken i att visuellt framföra och presentera ett arbetsområde i ämnet träslöjd. Uppsatsen handlar även om och hur slöjdlärare kan undvika onödig stress. Syftet med uppsatsen är att undersöka hur man i träslöjd kan utvidga sättet att presentera uppgifter för eleverna på ett inspirerande, innehållsrikt och konkret sätt. Genom att bedriva en praktisk visuell presentation i form av Power Point har jag fått en uppfattning om ett alternativ till den traditionella undervisningsformen i träslöjd. En utvärdering gjordes med eleverna efter Power Point presentationen och den visade bland annat att eleverna i år 4 fick mer utbyte av uppgiften jämfört med år 5-6.
Tysta flickor och högljudda pojkar : Observation om pojkars och flickors könsroller med utgångspunkt från likabehandlingsplanen
This study is about gender in classroom situations. The purpose is to examine if gender still exist although the government has educated gender teachers. I have been observing students during lessons and taken notes on teacher´s comments, which analysed. I have come to the conclusion that the students are awase of the power roles conserning gender and gender. In this classroom the heteronormativity still is a common phenomenon.
