Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

This thesis revolves around co-opetition and boundary spanning activities with IETF (Internet Engineering Task Force) as research case. The main objective is to through qualitative interviews and a passive observation of email conversations explore how the participants of IETF experience and is affected by a double membership where they sometimes are cooperating with their competitors. Theories states that boundary spanning activities can create role conflicts for these participants when different role-senders, IETF and the employer, send incompatible expectations. We also believe that this can have a negative impact on discussions and the standard development process, which is why we are conducting the passive observations mentioned above.The result shows that the environment of co-opetition is a contributing factor to role-conflicts. These conflicts appear when participants are forced to choose between the role as an employee and the role as an IETF participant.

The purpose of this thesis is to investigate the outreach services for children and youths in a specific area, in this case Västra Götalandsregionen. In particular this thesis will examine the development in the outreach services for children and youths from 1990-2010. Our thesis will also examine if the financial crises affected the outreach services for children and youths, and how control documents influence the work of the librarians. This study is based on interviews, document and literature studies. For the analyses we used Torgil Persson?s theoretical model.

The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

This thesis is a case-study of an ongoing court case between the Swedish Competition Agency and Växjö Municipality about a set-up requirement to the long-distance heating system for newly built private houses on municipality owned land. This requirement was set up as part of the municipality?s long-term environmental goals; however the Competition Agency claims that the demand is damaging the free market in the municipality. The purpose of this thesis is to determine which normative assumptions the decision makers have based their actions and re-action on, and whether or not these assumptions are valid, thru theoretical ideal types. This is determined via method of textual analysis.

The overall aim of this study is to investigate how social workers who are dealing with financial assistance are experiencing discretion in their daily work. The aim of the study is also to examine how social workers who are dealing with financial assistance relates to the controlling and the supporting functions of their daily work and how this in turn affects the attitude to the client. In order to examine the aim of the study, qualitative method was used. Eight social workers have been interviewed and presented with two fictitious cases that they have been able to discuss. Theories regarding the street-level bureaucrat and its discretion have been used to interpret and understand the collected material.

The purpose of the study is to describe how financial management functions within the individual and family care services in three mid-sized municipalities.27 interviews with managers and key personnel at three management levels in Örebro, Växjö and Jönkö-ping were conducted using a descriptive approach and qualitative method. In addition governing docu-ments and delineations in regards to these municipalities have been studied.The combined findings show that all municipalities have separate visions and control systems/models for their municipality with focus on management by objectives and politically determined goals, which in-clude economical measurements and requirements for the departments. Moreover, are also tracking sys-tems, which are described as following up on the results thru indicators and/or measurable goals. The municipalities utilize framework financials and budget processing on a high level and its timings appears similar in each municipality.Additionally the study has shown that there is a desire and aspiration to implement central economic goals in all three municipalities. The interviewees describe how they use their leadership to anchor, follow up and create participation in economic objectives and results thru instrumental and institutional leadership.

Assignment Birino AB are aware of the fact that their work tasks can be improved. The author?s assignment is to identify one task and improve it with relevant tools.Purpose See if the authors can improve health and effectiveness by changing the work task.Method The authors have conducted qualitative interviews, a quantitative survey and an experiment to see how the change worked in practice. The data the authors have collected will then be presented with relevant theories to answer our research questions/issues.Conclusion The authors have done a work process that can be used as a tool for change and improvement of health and effectiveness. This process can be implemented in different companies and not just the company that the authors have chosen to work with. .

The employment structure consists of different sectors, whose share of the total employment rate is all part of an economic structural conversion according to this thesis applied theoretical approach. A structural conversion, which consist of recurring crises, such as the financial crises in the early 1990s. This crisis and its effect on the Swedish economy is well-documented, while the shortage regarding the effect on a smaller scale, in a local and regional context, provides this thesis purpose. More specifically, a comparison between the two neighbouring towns of Malm? and Lund, will constitute the local contexts in this research.

Trading financial securities at stock exchanges and other authorized market places is today a particularly important socioeconomic phenomenon in many industrialized countries. A well functioning securities market is crucial for the economic development in these countries. The modern trading with stocks and other financial securities is characterized by the fact that the majority of the transactions at the stock exchanges are carried out through various intermediaries. The ultimate counterparties that are involved in a securities transaction (the seller and the buyer) are often unknown to each other. The anonymity in the securities trading implies several interesting legal problems.

Ever since it was first introduced in an article in the Journal of Finance 1952, Harry Markowitz? mean - variance model for portfolio selection has become one of the best known models in finance. The model was one of the first in the world to deal with portfolio optimization mathematically and have directly or indirectly inspired the rest of the world to develop new portfolio optimization methods. Although the model is one of the greatest contributions to modern portfolio theory, critics claim that it may have practical difficulties. Partly because the Markowitz model is based on various assumptions which do not necessarily coincide with the reality.

Inom en stor del av all systemutveckling sker testerna av systemet som sista punkt innan systemet sjösätts. Testdriven utveckling är en systemutvecklingsmetod där testerna istället skrivs först och också är det som driver utvecklingen framåt.Metoden höjs till skyarna av vissa och avfärdas omedelbart som onödigt omständig av andra. Vi vill med denna uppsats undersöka hur det ser ut i verkligheten och vilka faktorer som påverkar användandet, inlärningen och inställningen till testdriven utveckling.Vi genomförde intervjuer på tre stycken Örebrobaserade organisationer och tittade utifrån ramverket method-in-action på vilka faktorer som påverkade användningen och varför.Vi fann att utvecklarna närmade sig testdriven utveckling på väldigt olika sätt och grundade sin inställning mycket beroende på tidigare erfarenhet och inlärning ? oavsett hur lång eller kort den varit. Utvecklarna förväntas ofta bedriva självstudier utanför arbetstid ? något som inte alltid funkar som kunskaputvecklingsform då tiden utanför jobbet ser olika ut beroende på var i livet man är.

Municipal safety work is an issue frequently discussed. The new legislation about accident prevention obeys the Swedish municipality to present an action program for accident prevention. In Borlänge municipality there has been no sanctioned proposal for a program. This report presents the problems found and gives proposals for improvements in the future safety work. The guiding words should be unambiguousness, able to control and not too complicated.

The aim of this study is to analyze the justification of a financial incentive that rewards students who rapidly finish their studies within the language education ?Swedish for immigrants? (sfi). Thereby, we want to see what assumptions are made about the students, and relate this to experiences of the education at a local level. We applied a text analysis on a government bill about the incentive, which showed that the deficiencies in the education are said to be caused by the students? lack of effort.

Background: 2009 it has occurred a crisis in some of the member states of the European Union: Spain, Portugal, Italy, Ireland and Greece. Despite, some major banks in the world had begun to recover from the financial crisis that occurred from 2007 until 2009, there were still banks who found it difficult to survive. Greece is one of the countries that suffered from the financial crisis. The high budget deficit and the unsustainable debt are underlying the crisis.Banks as financial intermediaries have important function in a nation?s economy.
