Bakgrund: I takt med att konsumenters preferenser har förändrats, har företag fått överge massproduktion till förmån för produktionssystem som bättre avspeglar konsumenternas ökade krav på flexibilitet. Ett sätt för att överbrygga denna utmaning är att implementera lean production. Även om detta sätt att producera på har tydliga fördelar för dagens företag, verkar lean production även kunna medföra problem i avseende på att kombinera med den befintliga, i många fall, traditionella styrningen i företaget. En del av styrningen som verkar vara speciellt svår att kombinera med implementeringen av lean production rör mätningen av produktionen. Vid en närmare granskning visar det sig att det råder vissa motsättningar mellan traditionell mätning och lean production som kan påverka företagets beslutsfattande negativt.

Arbetet undersöker grafikkortets lämplighet att tolka L-system i realtid. L-system är ett strängomskrivningssystem som beskriver strukturen hos botaniska former. Lsystem tolkas med hjälp av sköldpaddstolkningen för att få en geometrisk tolkning. För att utvärdera om grafikkortet är lämpat att tolka L-system i realtid har två system implementerats. Det ena systemet tolkar L-system på processorn och det andra systemet tolkar L-system på grafikkortet.

Swedish agricultural businesses are facing challenges in order to achieve long-term profitability. The opportunity to improve profitability and efficiency on farm level may be enhanced by management. One way to work with leadership is to use Lean. It is a management system that aims to improve competitiveness. Currently, there is a project where Lean is implemented into 100 agricultural firms.

To reconstruct a building is a long-term investment for farmers and it is important that people with different qualifications are involved at an early stage for making the system adapted to the animals as well the animal keeper. Therefore, ethologists who can contribute with their expertise are needed to design the system and get it to function well for the animals.A Swedish farmer who planned to rebuild her stall for tied dairy cattle to a loose-housing system for recruitment heifers for milk production asked me as an ethologist to find a system which can be fit to her existing tie-stall barn for 30 dairy cows, considering the animal needs in terms of movement, social interactions and play behaviors, and to theoretically compare the system with other systems with respect to the behaviors mentioned.The theoretical comparison between different systems was made through a scientific literature review.In agreement with the animal keeper I set out to fit a system with feeding cubicles, a system with cubicles and a system with deep straw bedding to the barn. After measurements were taken and preliminary drawings were outlined it was found that only the feeding cubicle system was possible to fit to the barn.The space provided will limit the animals to perform some playing behaviors. To decrease aggressive interactions between animals even thought a limiting area it is possible to provide partitions between resources animals compete around to prevent that more than one animal can get success to the resource at a particular place at one time. To increase the animal movement in the system the water trays were moved to the outer wall instead of kept in contact with the stalls.Although this report provides guidelines for rebuilding, other competences regarding building construction and a pre-test of the suggested building solution according to Swedish legislation are needed before the rebuilding can start.The results are directed mainly to the owner of the barn, but the literature review can be used by other cattle farmers and might bring increased understanding of the possible effects of different building solution on the animals..

In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.

The process of producing a video game is one that goes through a number of phasesduring the span of the entire production. One of these phases is the concept design phase,which is part of the pre-production. This phase is an important aspect of the productionas it is where all the different parts and ideas concerning the game are brought togetherto define what the game is going to be. Though a clearly important part of the videogame production surprisingly little research have been done on the subject of conceptdesign. This thesis presents what place concept design has in the overall game productionand how the design process is handled.

Där empirin består av en semistrukturer intervju, telefonundersökningar samt enkäter. De teoretiska kapitlen är den sekundära datainsamlingen.

This report is written in cooperation with Skanska Sverige Hus Väst and it is discussing the role of site managers within the company. The report will bring up the demands that is put upon site managers and will also discuss stress related problems and how to change and develop the role as a site manager.We came up with three conclusions in this report. We believe that Skanska could develop VSAA to make it easier to use for site managers. We also believe that a further development of the project engineer is of great value, to give him or her greater responsibilities. The last conclusion is to change the responsibilities between the site manager and the production manager, to give the production manager a greater responsibility in the production..

Holmen Skog is one of the largest forestry companies in Scandinavia and they depend heavily on a large network of forest roads for production and logistics in connection to their forestry operations. The company recently introduced a new system for planning of road management. The system will also be developed with the intention to facilitate the monitoring of actions performed by road contractors. This report will provide information to support future decisions regarding further development of the system, after its introduction. In addition to a presentation of results from interviews, the report also provides a smaller study of the different subjects associated with roads, process work and process development. The study is largely based on interviews with road contractors that perform work for Holmen Skog today.

Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants. When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

This paper examines the texts written on shards from wine-jars found at El-Amarna, Tutankhamuns tomb (KV 62) and Deir el-Medina. Information concerning the administration of wine and its production, found in these texts, is examined. Wine was an important element in Egyptian society and a common iconographic motif in tombs at Thebes during New Kingdom.A survey on previous research on the subject is presented. This is followed by analysis of the different reoccurring elements found in the texts. A definition of the standard formulation of the wine jar label texts is given and the minimal level of information needed for the administration of wine production and distribution is identified. The chapter of the analysis deals with the various types of information given in the label texts, such as date, wine classification, and function.

This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to implement. Because of this, the text aims at providing a solid foundation of the mathematics needed, at explaining in greater detail the steps needed to solve the problem, and lastly at improving some aspects of the animation process as it has been described in earlier works. The aim of the system itself is to provide visually plausible renditions of animated fluids in three dimensions in a manner that allows it to be usable in a visual effects production context. The novel features described include a generalized interaction layer providing greater control to artists, a new way of dealing with moving objects that interact with the fluid and a method for adding source and drain capabilities..

This study was carried out in Jordan with the purpose to investigate the bacterial microflora of egg shells from cage systems and from deep litter floor systems. Another aim wasto get a general impression of the hygiene, at farm level, of egg production in Jordan andthe factors affecting it.Eggs from two cage systems and three floor systems were analyzed, regarding bacterialcontamination of the egg shells. Egg samples were taken from the storage room, the eggcradle in the cage system and from the nest and floor in the floor system. To get a generalimpression of the hygiene at the farms, swab tests and air tests were performed. Swab testswere performed with a sterile cotton swab at the same units as the eggs were sampled andair tests were performed by opening petri dishes where the hens were staying.

This study includes a life cycle assessment, LCA, on an ecological produced cotton shirt for the company Reflective Circle, which designs ethical and ecological clothes.Initially were cotton farming and textile production studied to gather basic knowledge about the processes. Since this shirt is being ecological produced in the whole production chain, we studied what an ecological production means, but also how a conventional production works. When this was done we could start to discuss the differences and similarities between the production of the shirt and general conventional production.When the LCA was first initiated, the main focus was on the green house gas emissions from the manure at the cultivation. Thereafter the process steps such as picking, ginning, carding, spinning, weaving and sewing were being studied. The picking is done by hand, but the rest of the processes are handed by machines which consumes energy.

Because of the large economic growth in China there are many companies who have economic interests in the Chinese market. Also in the forest market companies have started to invest in China and the interest for the market is growing. The question is how the Chinese forest market will develop in the years to come? How will China?s entry on the market of forest products affect the global forest market? The purposes of this study are to describe production, consumption and trade of forest products, and China?s possible competitive advantage in the forest industry. The purpose of this study is also to describe how China?s entry on the forest market affects the world market of forest products.
