Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased. As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.

I denna rapport har vi undersökt hur utvecklarna tagit hänsyn till användbarheten för slutanvändarna vid utvecklingen av ett säkerhetskritiskt system. Resultatet erhölls genom en empirisk fallstudie på två företag som utvecklar säkerhetskritiska system. Datainsamlingen bestod av intervjuer med personer som varit delaktiga i och har kunskap om utvecklingen av systemen som ingick i vår fallstudie. Sedan analyserades insamlad data mot teori inom Människa ? Dator ? Interaktion (MDI) samt teori om säkerhetskritiska system.

This study analyses the economic consequences due to ethanol production in Eastern Sweden. The analyses consider the cooperative and the farmers as one vertically integrated company. The area that found the market in this study is illustrated in figure 1. The analyses assume that all members act jointly with the objective of maximizing joint profits at the farm level as well as at the cooperative firm. A mathematical model is created to calculate the optimal use of arable land.

Abstract New methods, techniques and tools for the building industry are constantly being developed and improved and launched on the market. The problem in the building industry development is not that the products are not good enough. The problem is instead that the existing construction companies do not choose to use these innovations, instead they continue to employ the technologies they already possess and master. This leads to the fact that the construction industry is, in the public eye, beeing seen as a conservative industry. AquaVilla is a company that basically produces houseboats.

This thesis examines how knowledge management professionals use trust as a component in the creation of knowledge management systems, and what methods they use for building trust.Adopting a grounded theory approach, interviews with 8 knowledge management professionals active in different industries served as the base for an analysis that identified trust to be the single most important common factor in the data. The concept of trust used by the informants was identified as relating to the knowledge management system itself, rather than other users, employees or groups in an organisation.Building trust, the KM-professionals mainly focused on three methods: simple solutions, system superiority, and implementation security. Using these methods, the KM-professionals seek to ensure system trust by creating opportunities for users to obtain positive experiences of using the system, and thereby generate a foundation for a trust-based relationship between the user and the system..

Skanska is using work schedules that are specifically designed for employees in the production. These work schedules are called best practice. These are guides containing technical descriptions, design references, capabilities, etc. for work activities. This support function facilitates the work preparation and planning of future work.

A report has been made at a company in Borås at a company called ACG Nyström. Thecompany is today international and is marketing advanced equipment, systems and furthereducation to the manufacturing industry. A part of ACG Nyström?s production is a machinethey call Unimat. ACG Nyström doesn?t just stand for the actual production of the machine,but also for assembling and installation of the machine at the final customer.

The goals of this Bachelors? Thesis were to establish the production loss through the VTIS1 Pasteur at Arla Foods Linköping dairy and then suggest simple but effective solutions to minimize the losses for each production run. If the timeframe allowed it, some of the solutions would be implemented and tested in full production to determine their impact on economic and environmental savings.The very first step of this project was to establish the statistics over what losses there is in the production pipeline through VTIS1, from milk and powders in mixer tanks to finished and packed products in cold storage. Then, when knowing how much product was actually lost and where, those bottlenecks could be pinpointed and examined more closely. At this stage the focus was switched, from the otherwise complicated and broad manufacturing process, to the VTIS1-aggregate, since early data indicated there were quite substantial losses there.In conjunction with this project Arla Foods purchased an absorption photometer-measuring device (OPTEK AS16) that could be inserted straight into the product stream out of VTIS1, allowing real time measurements of its optical density.

The purpose of this literature review was from dairy cows? behaviour and welfare point ofview describe how feed bunk and cubicles in a loose house system should be designed. Todaydairy cows in Sweden and in the world have high demands because of a high milk production,stress and higher risk of being afflicted with diseases. Through selection in breeding the bestquality can be performed, but high demands of the environment for the dairy cow is above allalso important for a good welfare and for a good milk production. Feed bunks and cubiclesare just some parts to be designed in the best way for a good animal welfare.

Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.

The aim of our master thesis is first and foremost to win the competition One Prize - mowing to Growing: Reinventing the American Lawn, announced in USA by the organization Terreform 1, the first of December 2009. Apart from winning the competition we have also tried to reach a deeper understanding of food production today and its future possibilities. Our ambition to present a winning design proposal has to a large extent decided the structure of the entire thesis. Our completed and submitted design proposal - growforgold.org - is a way of addressing urban food production in a creative way, keeping the sovereignty of the individual in mind. Instead of presenting a place-specific design solution our proposal aims to create incentives and possibilities for urban farming to take place anywhere and anytime. Our submission to the competition represents both a tool and a platform which, put in practice, could make landscape architecture happen through the hands of the individual.

The soybean can be used in multiple ways, and its high oil content makes it suitable for extraction. Soy bean meal, a by-product of the oil extraction, is a good source of protein with a high feeding value, and is therefore used in a number of different animal feeds. Further, soy bean meal has a low production price, which is one of the reasons for the extensive export of the product. There is a great demand for vegetable-based proteins, especially in the organic production where synthetic amino acids are banned. However, the current production of soy beans is not environmentally sound and that combined with the long transport distances amplifies the need of finding a locally produced protein source.

Denna rapport tar upp problem med revisionskontroll i realtidsbaserade kollaborativa system. Enligt Fan & Sun (2012a); Fan & Sun (2012b) behöver man bryta kraven som definerar realtidsbaserade system för att uppnå detta.Den stubbaserade lösningen som beskrivs i rapporten lyckas minska antalet fel i testfallen som utförts i fallstudierna. Genom att implementera personliga editeringsflikar och stubbar är det möjligt att ha revisisionskontroll i ett realtidsbaserat system. Dock för att detta ska vara effektivt och användbart bör detta endast användas i specifika fall och med noggrann granskning.Fallstudien som genomförts visar inte på några imponerande siffror men en förbättring är fortfarande möjlig vid specifika fall..

This essay focuses on the term usability while conducting a user centred system design. Usabilitymeans to what extent a user can use a product to achieve effectiveness, efficiency and satisfaction.Development using a user centered system design means that knowledge about the end-users andit?s opinions becomes a crucial part of the development process. The question of this essay is if usinguser centred system design will lead to good usability.We used methods from a user centered system design point of view while developing an applicationfor a Swedish bookstore company called Bokia AB. This included user and task analysis following by aclose relationship between the developers and end-users by using sketches and showing themprototypes of the system while collecting feedback.After concluding our case study we determined that using methods from user centered systemdesign could be used as a great tool to further improve the usability and to improve an applicationssuccess chances..

The release of green house gases and the environmental impacts humans have on the environment are huge and might cause irreversible changes to our earth. Meat is considered to have large impacts on the environment, especially beef meat and therefore there have lately been considerable discussions on the sustainable level of meat consumption and production. The main goal with this thesis is to study sustainable meat production and meat consumption in the county of Dalarna in Sweden. Indicators for sustainable meat production and meat consumption were developed and applied on three cases. Interviews were carried out with a municipality in the region that represents the consumer and three beef farmers that represents the producers.
