Storleksoptimering av en etanolfabrik för integrering med ENA Energis kraftvärmeverk. : Baserat på en regional energibalans mellan tillgång på etanolbränsle i Enköping kommun och producerad etanol med hjälp av tillgänglig ånga från ENA kraftvärmeverk.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

Factors for success in Swedish biogas : a study based on the Swedish agricultural sector

The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection. This stresses a development towards production methods of renewable energy. Among the existing methods, biogas is presented as an attractive alternative.

En analys av vagnparksplaneringen i etthyrbilsföretag utifrån ett leanperspektiv.

The purpose of this thesis is to identify the factors that drive efficiency and effectiveness in technical development projects performed at A?F?s department of product development. In addition to identifying and analyzing these factors, the thesis also analyzes what needs to be taken in to account in order to implement a measurement system that is able to both monitor and control the identified factors.The thesis has been performed in a qualitative manner. It is based on interviews with people from several different technological companies, within different lines of business, all of which are customers to A?F?s department of product development.The results show that there are seven critical factors for project efficiency and effectiveness.

Biogasprocessen : Bestämning av verkningsgrad

Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

Självbestämmande och inflytande utifrån LSS värdegrund : En studie av brukarnas självbestämmande och inflytande i vardagsrutiner ur ett assistentperspektiv

The purpose of this study was to find out how special needs users ' autonomy and influence in their daily routines is described by their assistants. What interpretations of the concepts of self-determination and influence on special needs users' daily routines emerge from the assistants statements and what conditions can be seen? To reach a conclusion, focus group as a method was used. The focus group met twice to discuss this topic. The diamond method was used as stimulus material to support the discussion in the focus group.

ROLL UP! Produkten som förenklar hanteringenav en dragfjäder : Ett examensarbete som startade med en enkel idé och utvecklades till en prototyp

This report presents an independent thesis corresponding 15hp and was carried out on Högskolan in Halmstad during the spring of 2014. The thesis is the final course which ends a three-year mechanical engineering program with focus on technical design.The thesis started in an operation which electricians are exposed to every day. The operation in question is cable laying or wiring. The tool they use is called a tension spring and is a long and stiff wire, usually made out of nylon or fiberglass. The tension spring is fed through pipes in the walls and brings the desired cables with it on the way back.

Identifiering av slöserier på Lundbergs Plåt AB

Lundbergs Plåt AB is a small company situated in Jönköping. Their main task is to process different kinds of steel such as stainless steel. Lately, they have shown an interest in Lean production.On the basis of the situation mentioned above, we developed the purpose to find and decrease the non value-added wastes in the production at Lundbergs Plåt AB. Out of this, we also developed and answered two questions: Which wastes can be found with help from a value stream mapping (VSM)? In what way can these wastes be reduced and how can these reductions contribute to an improved production? VSM is the method used to find the non value-added wastes.

Transportation of pigs might be a welfare problem. Stress during and after transportation can negatively affect the meat quality or cause carcass damages, which leads to major economic losses every year. The transportation chain can be divided into several stages; loading, transport and unloading. This literature review focuses on unloading of pigs from a transport. When arriving at an abattoir pigs can be fatigued and need to be as smoothly unloaded as possible.

Lokaler och redskap i Idrott och hälsa : En studie om lokal- och redskapstillgångar på grundskolan och gymnasieskolan

Vid starten av idrottsundervisningen på 1800-talet fanns en problematik gällande lokalbrist. Denna problematik fortsatte och aktuell forskning visar att endast 70 % av Sveriges skolor i början av århundradet hade regelbunden tillgång till en gymnastiksal eller idrottshall. Kopplat till denna problematik saknas forskning kring huruvida det finns tillfredsställande redskap till förfogande eller ej. Därför syftar denna studie till att undersöka vilka lokaler samt redskap, fasta och lösa, som idrottslärare har till sitt förfogande i undervisningen och i vilken utsträckning de har det. Denna studie baseras på en webbenkät som har skickats ut till idrottslärare för att uppfylla syftet.

The graduation essay has been carried out in co-operation with Kalmar Industries in Lidhult, Sweden. The purpose of our essay was to develop a complete construction solution on a hoist that could lift a laying wheel, lift it up and then turn it 90 degrees. After that the wheel shall be placed in a special holder.The background of the essay is a record of reports of damage wheels when they been incorrect lifted with a forklift. The hoist shall be used together with the same forklifts that manage the wheels today. Together with our instructor at Kalmar Industries we developed a requirement specification and from that we got free hands.However this was not the main task from the beginning, then a simular hoist should be develop but used directly in the assembly workshop without using a forklift.We started to find principle solutions that later was evaluated against the requirement specification.

Från Skiss till Diss

Over the past decade, the fashion industry has experienced a relatively high rate of consumption with material and clothing becoming increasingly subject to waste and disposal. As a result of the increased awareness within the industry the interest in CSR (Corporate Social Responsibility) amongst retailers has increased substantially in an attempt to shy away from the critically amplified media attention. In addition the underlying demand from external stakeholders has forced companies to ensure they focus and act upon each stage of the product life cycle.This study provides a further in depth analysis of the fashion industry and conveys the key messages and steps that firms are taking in response to the external pressures and requirements based on four different merged process areas. This research paper examines the impact of CSR on two Swedish fashion retailers Åhléns and JC and shows how accountability relates to the external expectations and norms that prevail in society. The result shows that the firms do meet the demands within each sub category as a response to market demands.
