Radomoptimering för luftburna störsändarkapslar
These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..

The new flyfishing reel shall be innovative and reduce the number of components in fly fishing equipment.The solution for this is to create a fly fishing reel that is collapsible and can be used for all typesof fly fishing.The thesis started with a history of fly fishing and the equipments that have been used for flyfishing in the past and what is used today, in order to get an idea how fly fishing haveprogressed. A frame of reference was then compiled to get an idea of the forces and surroundingsa fly fishing reel will be exposed to.
Internationalisering av innovationer : innovationsföretags möjligheter under en internationaliseringsprocess
The purpose of this study is to identify a successful way of expanding a business on a global market, focusing on innovation products. An analysis was also made to see how internationalization theories are useful in businesses with innovation products. Four companies have been interviewed where two of them have innovation products (Proline AB and Q-Med AB) and the others are widely successful in exporting to a global market (Safegate Group and Weda Poolcleaners AB). Furthermore four interviews have been made with support organizations that have great experience in helping companies in this area (Svenska Uppfinnareföreningen, Almi Företagspartner AB, Exportrådet and The Swedish-American Chambers of Commerce).One of the results that can be identified is the diverse view and will to expand the business. The inventor often has a born global strategy in mind whereas the helping organizations rather expand step by step and only to one country at a time.
Hållbar utveckling och CSR : En begreppsutredande studie
Bakgrund: I Sverige drabbas cirka 30000 personer av stroke varje år varav 20000 är förstagångsinsjuknade och cirka 10000 dör varje år. Cirka 85 % får hjärninfarkt och 15% får hjärnblödning. Nedsatt gångförmåga är vanligt bland personer med stroke och styrketräning och gångträning är två metoder som kan användas i syfte för att förbättra gångförmågan Syfte: Syftet med studien var att sammanställa litteratur kring uppgiftsorienterad träning och styrketräning som behandlingsmetod för att förbättra gångförmågan för strokepatienter. Metod: Litteratursökning på databaserna PEDro och PubMed med sökorden stroke AND gait i kombination med training, resistance training och strength resistance training samt task-oriented training. Efter att ha gjort sökningarna och sållat hittades 12 artiklar som ansågs relevanta för studien.

Cirkelmodellen i praktiken : En studie av hur SFI-elever upplever cirkelmodellen
This essay is an examination of the examples in Kant?s Critique of Judgement. The examples which I have focused on all converge in an idea of wildness. These examples of the beautiful are illuminated by a culture-historical perspective, where the literary and scientific travelogue genre is of great importance. Apart from being exegetic and culture historical, my method is also analytic.
Betydelsen av hästens hud och päls för reglering av kroppstemperatur i kyla ? vad händer vid klippning och täckning?
The horse is a homeothermic animal and to keep a constant body temperature in winter season is important. Acclimatisation is to provide means for a good thermal insulation consisting of skin, hair, and an outer air layer. The skin covers the horses body and it is composed of three main layers where the top layer of the epidermis consists of dead keratinized cells that are constantly being sheed. The dermis is composed of collagen connective tissue that give the skin its strength. The bottom layer with subcutaneous fat provides a thermal insulation and can be used as an energy reserve in cold weather.

En analys av en mattestuga : - elever med matematiksvårigheter
Mergers between companies has become more and more common in Sweden and in the rest of the world with the motive to increase the competitive strength in the current markets and has an important role within organisational development of companies. When organisations merger there is not only buildings and objects that are put together but also their individual organisational structures, people, values and cultures. This can be a difficult process and can affect many people in how they think conscious as well as unconscious, feel and react.The purpose of this thesis is to gain a deeper understanding of how employees are affected following a merger when changes in the organisational culture come up, and how these changes are expressed.This thesis is delimited to investigate only one company, Skruf Snus AB and only focus on their business and employees in the region of Stockholm. The thesis contains a qualitative investigation with semi structured interviews that has been carried out with eight employees at Skruf Snus AB. The thesis is partly based on a model of Schein which describes the different levels in organisational culture and partly on some theories about reactions to change in relation to the integration between the employees following a merger.The results of the investigation indicate that with a merger the whole organisational culture is affected and therefore also the employees.
Analys och kontroll av hållfasthet på grenställsarm
The thesis was done in collaboration with EAB situated in Smålandsstenar. In the initial discussion faze on doing a thesis with them there was a need to analyze and ensure the strength of an existing product, cantilever racks. This included performing FEM calculations on a model and comparing the results with physical tests.EAB has two models of cantilever racks, a light duty and a heavy duty. Within the heavy duty model series there are five product variants that differ in both size and load capacity. We will be working with the product variant with a load capacity of 1000 kg/arm which is the variant that is in the middle of the series.When we started work on the thesis we did a literature study and couldn?t find any well defined methodology that integrates both product development and computer aided design analysis.
Förvärv och Företagskultur
Background: Acquisitions are a well-known method for increasing company size and strength on the market. But to reach the targets set, more than just a positive economic calculation is required. An atmosphere that supports the company's integration is needed, for which it is of great importance for management to understand the underlying sets of values that exist in the organisation, and to take into consideration the way they might become an obstacle or a tool for a successful integration. Purpose: The purpose of this thesis is to explain and understand how cultural change occurs and how it affects the employee, as a smaller company is bought and integrated into a larger organisation. Procedure: The analysis is based on theories on organisational culture and organisational change.
Undersökande journalistik : En analys av Uppdrag gransknings dokumentär om IKEA
This essay is about power in the classroom. It is about the power dimension of the student-teacher relationships that arise in that space. The overall aim has been to investigate which categories are fruitful in a power analysis of these relationships. My aim has therefore been to develop power categories and to use them to identify and to categorise cases of power interaction that take place between those particular actors in that particular setting.In order to gather material for my study I have both read literature that approaches the study of the student-teacher relationships from a power perspective and done a series of observations in a high school.My theoretical frame comprises a concept of power and a series of power categories. These categories include strength, authority, inducement, coercion, violence, resistance as well as to possess power, to have power, to exert power, the scope of power and the base of power.
Träning och kost på ett idrottsgymnasium -En explorativ undersökning som handlar om sambandet mellan kost och träning på ett ishockeygymnasium : Exercise and nutrition at a sportsgymnasium -An explorative survey of the relation between exercise and nutrit
This is an examination report in physical education. It focuses on the relation between excercise and nutrition and how this relation works in an icehockeygymnasium in a midsized city in Sweden.

In this examination report you can read about how the food is composed and how many meals the students are offered through their education program. The persons that I´ve interviewed are the head coach, the president of the school restaurant and three students.The students have practise in the noon two times a week, on Tuesdays and Thursdays.
Inomföretagshandel : en deskriptiv studie av de gängse ekonomiska modellernas förmåga att förklara inomföretagshandel
This essay in economic geography describes what intra-firm trade as a concept is and different ways to determine in which cases trade is to be labeled as intra-firm trade (IFT) or not. The method used by the author is most easily described as descriptive. This method was chosen in order to test if existing theories; classic and neoclassic economics, new trade theory and international business studies, are capable to explain the phenomena of IFT. The theories are tested trough primary and secondary literature but also trough reasoning by the author.The conclusion is that the most reasonable way to determine whether trade occurs intra-firm or not, is to decide upon a 5-% rule where it when one part owns 5-% of the voting strength in the other company is to be considered intra-firm trade. This is a conclusion based on several reasons; the strongest one being that a common view on IFT could boost comparative studies as the U.S already collects data based on the 5-% rule.Classic and neoclassic economics are incapable of explaining IFT as aprerequisite for these theories is that markets are perfect.
