This report investigates a possible solution to the problem with adapting wave powerplants to work in countries with tidal water. The wire connecting the buoy at the surface with the generator at the bottom needs to adjust to the varying water depth. Our solution to this problem is to attach the wire to a jack which is then placed inside the buoy. The jack is then powered by an electric engine. The report discuss what forces the buoy will be exposed to and then the structural integrity of the design is evaluated through simulations.

Stötvågsbehandling har använts vid muskuloskelettala besvär sedan ca 15 år tillbaka. Behandlingen benämns ofta som ESWT (extracorpeal shock wave therapy), och består av mekaniska akustiska tryckvågor som penetrerar vävnad. Dess smärtmekanismer och läkningsmekanismer är fortfarande oklara. Plantarfasciit/hälsporre och akillestendinos är diagnoser som kan behandlas med stötvågsbehandling. Att kartlägga evidensen för stötvågsbehandling vid plantarfasciit/hälsporre och akillestendinos.

I studien kom vi fram till att kapitalstrukturen inte alltid är uppbyggd på ett likartat sätt.Utifrån de valda förtagen i IT branschen påvisas det att kapitalstrukturen inte är utformad på samma viss. Tjänsteföretagen påvisar en likartad kapitalstruktur med avvikelse från företaget New Wave. Däremot i Industri branschen var kapitalstrukturen utformad på en likartad modell..

Den här studien bygger dels på en narrativ analys av artiklar i Smålandsposten och deras gestaltning av Orrefors Kosta Boda, dels på en fallstudie över Orrefors Kosta Bodas externa och interna kommunikation där den externa kommunikationen hamnar i fokus. Problemformuleringen ställer följande frågor:Hur konstruerar de lokala medierna bilden av Orrefors Kosta Boda och vad är det som utmärker deras texter?? Kan en organisation få publicitet i de lokala medierna utan att använda sig av en medveten kommunikationsstrategi och hur går det att förstå detta?? Om Orrefors Kosta Boda använder sig av kommunikativa strategier för att synas i de lokala medierna, vilka är dessa?? I vilken uträckning har Orrefors Kosta Boda AB samma budskap till sina medarbetare som till medier?? Vilken relation och kommunikation har Orrefors Kosta Boda med de kommuner där de har sin verksamhet?Studien bygger på fem olika nyckelord: organisationskommunikation, ledarskap, strategisk kommunikation, integrerad kommunikation samt mediekonstruktioner ? narratologi.Resultatet visar att det går att få publicitet utan att använda sig av en medveten kommunikationsstrategi gentemot medier. Det finns flera andra faktorer som spelar in förutom en riktad marknadsföring. I det här fallet har Orrefors Kosta Boda blivit uppköpt av New Wave Group som har skapat stort intresse i både medier och affärsvärlden.

The aim of this report was to investigate if Sweden can have 100 % renewable electricity production in the year 2050. The conclusion is that it is possible but under certain conditions. For instance wave power must be in commercial use. When wind power and solar power represent a large percentage of the electric production there will be a lack of electric power during the winter but during the summer there will be a surplus of electric power. Both the surplus and the lack of electric power need to be taken into account.

Corporate Social Responsibility (CSR) is about facing responsibilities towards a company?s employees, customers, stakeholders, suppliers and the environment. As customers and consumers came to seek companies that were dealing with CSR a rapid wave of ?forced? implementations of social responsibility began. Fair Travel Tanzania, which has CSR as the foundation of the company, says that they are transparent about what they do and how they give back to the locals, could it be a problem with this? And how do they actually give back to the locals? Is it possible to measure the impact of CSR activities within the company? And if so, how?.

In today's society there is a significant focus on energy efficiency. Despite this, people leave lamps, televisions and computer screens etc. powered on unnecessarily. The goal of this project is to build a simple prototype for home automation where a user, via an application on a mobile phone, can switch on and off the power of an electrical products in the home and as well as being able to check whether such products are switched on or off. The prototype will also collect data on power consumption for these electrical products.

The aim of this project is to find a concept solution for a wireless transmitting system, installed to transmit data from a hydrophone of the ocean floor down by a wave power generator to the office on shore. The project is a literature review in which previous observations and tests are analyzed and put together to find a solution. The result was a comprehensive solution that includes an acoustic modem to transfer captured information from the bottom to the surface, wirelessly through the water. The information is then sent fron the surface on radio waves through the GSM network to the office on land. Between under and over water there are components to convert information between acoustic waves and radio waves, but also various types of modulation, such as amplitude and frequency modulation is required..

The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical function into the FPGA The logical function corresponds to a modeling of the music signal and the modeling can be described as a comparator which compare the music signal with a triangle wave and as a out signal produce a pulse width modulated (PWM) signal. The report is also a review and evaluating of two different modulating technologies, AD- modeling and BD-modeling. A detailed part about how the H-bridge was designed and how it works. The result of this project is a working audio amplifier to a significant lower price than the products in todays market..

The purpose of this essay is to study how feminists portray themselves and their opinions about gender issues and other political matters in popular feminist blogs. The blogs that are studied are Lady Dahmer, Fanny Åström, Hanapee and Genusfolket. The overall essay questions are: How does the feminist bloggers present themselves? Which subjects are discussed in the feminist blogs? Which rhetorical devices does the feminist bloggers use? The theories that are used to answer the essay questions are the four spheres where there are inequality between the sexes, theories about third wave feminism, the rhetorical concepts ethos, logos and pathos and the SPADER-model for writing good argumentation. A descriptive method is used to study how the bloggers present themselves, a quantitative content analysis is used to count which subjects the bloggers write about and a qualitative rhetorical text analysis is used to study the rhetorical devices the bloggers use.The result shows that the two bloggers Lady Dahmer and Fanny Åström describe themselves with provocative words while the other blogs have more neutral descriptions.

I detta arbete studeras möjligheterna att använda s.k. "Frequency-Modulated Continuous Wave radar" (FMCW-radar) för att mäta avstånd och radiell hastighet till ett mål. Vidare undersöks möjligheten att använda en följd av sådana mätdata för att skatta banparametrar för ett mål. Vi utför en två-dimensionell Fouriertransform på radardata. Genom att söka upp maximala värdet av transformerade datas absolutvärden erhåller vi en grov skattning av avstånd och radiell hastighet.

During the twentieth century, mergers&aquisitions have occured in waves where times of low activityfrequently has turned into periods of high activity. M&A:s have been of increasing numbers and growing size, which was extra evident during the last wave during the 1990:s. What are the motives that has made M&A such a widely used strategy? Are there similarities within and across industries regarding merger motives? The empirical material consists of primary and secundary data collected from two mergers in three industries respectively; manufacturing, banking and IT. The analysis make use of three different perspectives, the reason for this being to create understanding and furthermore illuminate the complexity of the problem.

Ett digitalt vågfilter av Richardstyp har implementerats i en FPGA på ett utvecklingskort. Sampel kan skickas till filtret och mottas från filtret via serieporten på en dator. Metoden som användes är att en modell av filtret konstruerades i Simulink. Filtret har modifierats med avseende på skalning, brus och stabilitet. VHDL-koden till filtret genererades i Simulink genom att bygga modellen av Xilinx Blockset.

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.
