As part of an internship at Ericsson, this report was written to enhance the understanding of how it is to develop a system that is well established at the workplace. To improve an already existing system is not always as easy as many developers may think. In this report the pros and cons of developing an already existing system has been researched and analyzed. Do note that the results are only from one development of a specific system and that comparison of other developments has been made from other reports and not from experiencing it firsthand. It was found that the choices made can have an impact on further developing and it is important to write down what has been done.

I detta arbete har en studie gjorts för att undersöka en metod i MSC.Marc för att reducera analystiden vid svetssimulering. Arbetet är utfört åt Volvo Aero. På Volvo Aero utförs svetssimuleringar vilka är väldigt tidskrävande. Dessa görs för att kunna förutsäga formförändringar och spänningar i modellerna. Eftersom svetssimuleringarna kan vara väldigt tids och minneskrävande finns det mycket att vinna om man kan förkorta beräkningstiden.

We can see an increasing middle age population in large parts of the world. People are healthier when they retire than they were before. As people grow older, physical and mental changes occur that can make the use of cars more complicated. The possibility to travel by car is important for many people to keep the connection with the society and to feel independent. How can Volvo cars face the needs of this growing target group?The purpose of this project is to make a car concept that responds to those needs, it is therefore important to maintain the values of Volvo cars.

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

Within today?s organizations there is continual development work to increase efficiency and the power to compete at the market. Production development with focus on continual improvements constitutes an important part of the daily work within a lot of organizations today.The purpose of this study is to contribute to a part of the development process that Volvo Penta factory in Vara has in mind. A description of the current situation was compiled by mapping the internal runnings and material flow throughout the factory. A new suggestion for a layout and a comparison with the current situation will assist with creating a factual basis for the development of a new goods reception.A study was made where the volumes and the quantity of the daily arrival goods were settled.

The purpose of this report was to compare two different options for expanding of an existing pig farm. For the time being there are low prices within the agricultural market of pig production, and it is interesting to see if it is worth expanding or not. The two different options this report is based on are: expanding from a herd with 50 sows in breeding gilt production to a herd with 100 sows in breeding gilt production (option 1), or expanding to a herd with 140 sows in breeding gilt production (option 2). The number of pregnant gilts produced per year will stay the same for both alternatives; about 300 pregnant gilts per year. The rest of the breeding gilts will be sold at a weight of 25 kg. The pigs that are not sold as breeding gilts (e.g. castrates, and female pigs that are too small or that have disorders) will be kept on the farm as growing-finishing pigs until 120 kg of live weight, and then sold to the slaughter house. By using the existing buildings, even after the expanding, the investment costs, and thereby costs for housing, were kept as low as possible.

The purpose of these theses is to show the financial economical situation during the change from conventional dairy production to ecological production. The thesis is accomplished by collecting information from literature and interviews where needed. The target group of these theses is dairy producers who will transform their production from conventional dairy production to certified ecological dairy production. The theses emphasise on the economic situation during the adjustment years. For this I have studied a presently producing dairy farm.

A number of studies have been made to examine several aspects of voice production in individuals with different types of hearing impairments. Most of the studies were made to explore the impact that hearing aids have for people with severe or congenital hearing impairment. So far it has been confirmed that there are changes regarding voice production in these individuals. A group that has not been investigated regarding voice production to a larger extent are hearing aid users with an acquired hearing impairment. In the present study the voice production of seven individuals, four men and three women, with a moderate acquired hearing impairment is examined.

BackgroundThis paper is based on an issue raised by the organization Energigas Sverige, which together with the Ministry of Finance has posed the question about the fiscal impact of an increase in biogas production. Since the fiscal effects of an increased biogas production are both positive and negative, due to reduced use of fossil fuels, we want to investigate this further.PurposeThe purpose is to describe and explain the obtained fiscal impacts of an increased biogas production and based on our problem: ?What are the obtained fiscal effects caused by an increase in biogas production?? we could see the following fiscal effects: positive impact on employment, increased revenues of social security contributions and income taxes, reduced unemployment costs and reduced tax revenues on fossil fuels. These effects are summarized in a negative tax revenue of 2,6 billion SEK. Along the summarized negative effect we also accepted one of the two prepared hypotheses, which stated that an increase in biogas production leads to a negative fiscal impact. Design/Methodology/ApproachWe have chosen to work from an Anglo-Saxon scientific tradition and furthermore, we have a positivistic approach when we want to explain the relationship between cause and effect of an increase in biogas production and the following fiscal impacts.

The aim of this literature review was to make a comparison between the feeding requirements of Swedish reindeer (Rangifer tarandus tarandus) and meat producing cattle (Bos taurus) within farming. Reindeer are an intermediate feeding type; they have the ability to adapt to short term seasonal changes in food. They avoid eating fibre as much as possible and display highly selective behaviour while foraging. Adaptation to harsh environments with a limited amount of food has made reindeer dependent upon easily digestible food and consequently their digestive systems are less capable of processing plants with high fibre content. Herding is an extensive system which requires a significant amount of land and labour and describes the reindeer industry.

This project concentrates on musicians who work in a professional music studio.The task of this project was to design a new headphone system called Foldback system.The advantage of this system is that all involved in a music project could influence their ownlistening during the project. With a couple of adjustments should each and everyone get theirown individual listening from their headphone station.This report shows different methods, theories and results that came along in development ofFoldback system. The project has resulted in a finished product that will be in use atStudiomega..

Bakgrund: För att vara kostnadseffektiv och utveckla nya bilmodeller i snabb takt använder sig bilföretag av produktplattformar. En produktplattform är ingen fysisk produkt utan varieras med olika komponenter beroende på vilka delar på bilmodellerna som skall vara unika respektive vilka delar som skall vara gemensamma. Nackdelar med flera gemensamma komponenter är att slutprodukterna blir identiska i flera avseenden, vilket försvårar varumärkets arbete med att göra produkterna unika och skilja de från konkurrenternas. En konflikt uppstår således mellan produktplattformens strävan efter gemensamma komponenter och varumärkets arbete med att göra produkten unik.Syfte: Syftet med uppsatsen är att utifrån de gjorda fallstudierna på bilmodellerna Volvo XC60 respektive Land Rover Freelander 2 som producerats på en gemensam produktplattform analysera och jämföra varumärkenas och bilmodellernas benägenhet att förmedla vad som är unikt i samband med en reklamkampanj.Genomförande: Uppsatsen är genomförd med en kvalitativ ansats, där intervjuer har genomförts. Den empiriska studien är uppbyggd av två deskriptiva fallstudier och jämförelser har gjorts mellan fallen för att se skillnader.Resultat: Uppsatsen har kommit fram till att varumärket är av stort värde för företag eftersom två identiska produkter producerade på en gemensam produktplattform kan säljas som två unika produkter.

The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value. Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.

A growing interest for the climate and the environment has led to an increased interest forenvironmentally friendly and renewable energy sources, such as biogas. Planning new biogasplants requires a decision basis including facts about approximate amounts of biogas possibleto produce at the plant. The purpose of this thesis is to develop a model that calculates theapproximate biogas and digestate production from a planned or existing biogas plant.Developing the model required a literature review and studies of calculations concerningbiogas and digestate production performed by WSP Sweden AB. As a complement to themodel development, facts about substrates for biogas production were compiled through aliterature review. In addition the methane potential from selected materials was determined bybatch experiments.

For a long time the Swedish forests were used by the landowner?s mainly for providing wood to the household itself. The wood was not, to a greater extent, considered a product to be sold. During the 1800s the industrial era led to a demanding need for wood in the industry and thus the use of forest, forest production kicked off. The forest production was not regulated by law, which led to a differentiated forest production over the whole country without consideration of re-growth.
