Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.

Skälby park is situated approximately 2,5 km northwest of the central parts of Kalmar and is one of fi ve town part parks. Originally Skälby consisted of a village of four farms. In 1965 the municipality in Kalmar bought Skälby and the agriculture ceased to appear. The land was parcelled out into plots and new roads. Only the area surrounding the old buildings remained, turned to a park.

Uppgiften är att utarbeta ett förslag på inriktning vid val av ett framtida markbaserat precisionsbekämpningssystem för den nya Försvarsmakten. Uppsatsen tar avstamp utifrån RMA, även kallad ?den nya krigföringen?, som antas vara den vision som gäller när det nya försvaret skall formas. Inledningsvis studeras de trender och pågående projekt som föreligger. Dessa får sedan lägga grunden för ett antal spelkort som bedöms utifrån de förväntade krav som kommer att ställas i framtiden.

Over the past one hundred years, there has been an increasing globalization and industrialization of the food systems. As a result, the distance between the production and the consumption of food has increased, both in time and space and in the minds of people. There is also an increasing concern for the environmental effects of industrial farming and the long distance transportation of food. Sustainable agriculture and efforts to build more sustainable food systems has emerged in opposition to the global food market. The definitions of sustainability usually include environmental, social and economical aspects. To build more localized food systems is seen as one way towards increased sustainability.

Detta arbete analyserar och exemplifierar initiativ för att skapa hållbara kollektiva odlingar på landsbygd. Arbetet undersöker hållbarhetsbegreppet och fördjupar sig i frågan om vad hållbara jordbruks- och livsmedelssystem kan vara. Främst studeras alternativa kollektiva odlingsmodeller som strävar efter att sammanföra konsument och producent, framförallt via CSA-kooperativ, Community-Supported-Agriculture. Även begreppet Civic Agriculture, CA, uppmärksammas då det beskriver ett odlingsengagemang som går bortom de enskilda kooperativen. CA innebär ett förhållningssätt och agerande som verkar för lokalt hållbara livsmedels- och jordbrukssystem, och som utgår från den lokala platsens behov och förutsättningar med hänsyn till dess ekologiska- och socioekonomiska kontext där den passiva konsumenten istället blir en aktiv ?matmedborgare?.I arbetet framkommer det att långsiktigt hållbarhetsarbete behöver få utgå från varje enskild människas situation, och baseras på lust.

In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

The world?s population reached more than 6.9 billion people in July 2011. It is expected that the population growth during the next 40 years will take place mostly in low-income countries and the population increase will be 2.3 billion people during 2011-2050. A rapid urbanization is also expected to result in 57.7 per cent of Africa?s population living in urban areas in 2050.

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

This essay discusses the Laholm?s bay and its eutrofication problems. The question of issue is: Have the efforts to limit the eutrofication in the Laholm?s bay been effective? What is the local actor?s opinion whether the measures have been effective or not? What efforts have been made to prevent the leakage of nutrients from fields and forestland? The Laholm's bay is located in the south part of the Swedish west coast. The problem was noticed in the 1960´s by local fishermen that experienced a lack of catch.

The purpose of this thesis is to evaluate two pearl growing methods in ISI Web of Science. The methods tested are Find Related Records FRR, an automatic service that uses bibliographic coupling, and Author Keywords AK, where searches are performed using the two first keywords from this field. Both search methods were used on twenty initial documents and the first twenty hits were evaluated for relevance using a binary scale 0,1. The relevance criteria were based on specific information needs connected to every initial document. The measures used to evaluate the effectiveness of the search methods were Precision at DCV=10, P10, and Uninterpolated Average Precision AP.

De senaste decennierna har en rad streckkodstekniker utvecklats för att grafiskt representera digital information. Gemensamt för dessa är en strävan efter hög densitet, det vill säga kapacitet att lagra mycket data på en liten yta. Densiteten begränsas emellertid av kravet på precision vid tolkning av den digitala datan, eftersom felaktigheter i digital data kan resultera i omfattande informationsförlust.Analog information, exempelvis ljud, är däremot inte beroende av exakthet hos underliggande data i samma utsträckning. En analog ljudsignal kan beskrivas och återges approximativt, och ändå tolkas korrekt av en lyssnare. Detta faktum gör att det finns fördelar med att representera ett ljud utifrån dess analoga egenskaper.

This thesis examines the effects of proximity operators and query expansion with synonyms on retrieval performance. The queries were expanded with synonyms and structured with proximity operators where the permitted distance between terms varied from 1 to 3. The expansion terms were selected from the online lexical reference system WordNet. Initial query terms were selected from 28 topics that contained compound words and were chosen on the basis of their expandibility. The English morphological analyser ENGTWOL was used for normalization of query terms.

The purpose of this thesis is to investigate and analyze existing law concerning joint owner-ship in agriculture and forestry businesses. Joint ownership often arises through a succes-sion of ownership, therefore we will go through the most useful methods.Even if the owners of agriculture and forestry businesses are getting older, the numbers of succession of ownerships are still low. A succession of ownership is important to plan and its time is demanding. Often it takes three to five years for the completion of a succession of ownership. Therefore, owners must start their planning in time and think about what is to come of their business.

Land management for food production is a fundamental human activity and one of the greatest challenges of the 21st century will be to increase the global food to accommodate a world growing to 10 billion or more people, while undergoing climate change. The increasing temperature and the current and projected increase in concentrations of CO2 lead to concern over possible impacts on agricultural pests. This assay is summarizing the knowledge of weeds in a changing climate in Sweden. Global warming and other climatic changes will affect the growth, phenology, and geographical distribution of weeds. The climate change will also affect the weed composition indirect by causing changes in the agriculture.
