The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

This thesis is conducted together with the environmental- and health department in Halmstadcommunity. The thesis is about allowance of bedding and water supply for pig farms inHalmstad community. These farms are chosen randomly from all of the pig farms inHalmstad community. It includes inspection of 27 pig farms and writing of a report. Duringthe inspections I study the amount of bedding, what kind of bedding, water supply andinjuries like lameness, shoulder-bone sore, ear-, flank- and pig tail biting.

 The english name of this essay is ?One man among many women?. This essay takes its starting point in the situation today with few male teachers in the earlier years of elementary school. I have decided to look at the small group of males that actually started the education to become teachers and why they did it when the profession as teacher today is low-paid, low status and is a profession with a large dominance of female teachers. I have chosen to write about this because of the importance for the children to meet both men and women as teachers in the early schoolyears.

This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

This degree project is based on identifying and allocation of costs in a packaging section at Electrolux Distriparts in Torsvik.The purpose of this thesis is to identify the costs that emerge when packaging different articles and show how the costs are allocated. The report also contains improvement suggestions about how the company can use the current computer system more efficient.The methods that have been used in order to approach the problem and the collection of information have mainly been literature study, interviews and observation.The work started with answering the questions; which expenditure cost and direct cost exist in the section, how can they be allocated, if improvement can be done and how the flow of information is supposed to happen.In order to answer the questions we used our former experience and the knowledge we achieved by reading literature, interview relevant persons in the company and observations carried out in the section.Through our studies, we came up with an Excel file, which is the groundwork for a template that can be used by the company in different occasions depending on the situation and need. It is important to remember to modify the template if the presumptions change. In the template, we have identified the different kind of costs that emerge when packaging different articles and we have also allocated the costs. In addition formulas and estimations that are necessary for the cost calculation are presented.The work consisted in making the groundwork for a template.

This thesis describes how the chip space and coolant channels are designed in today?s mills, the ideas behind the design and what is considered to be the best method of cooling. It contains ideas on how the chip space can be simplified. It contains several concepts on how the cooling could be designed for better efficiency and manufacturability. There are also suggestions on how the cooling could be stopped when the cutter isn?t cutting.

Syftet med arbetet var att undersöka pedagogernas inställning till lek i skolans lägre årskurser. Vidare att belysa lekens betydelse för den kognitiva utveckling och hur pedagogerna använder leken i sitt dagliga arbete. Metodern är en kvalitativ, halvstrukturerad forskningsintervju med hermeneutisk inriktning och bygger på intervjuer med sex pedagoger. Jag redovisar intervjuerna i fyra olika teman, som kom fram under analysen av intervjuerna. Sammanfattningsvis pekar resultaten av min undersökning på att samtliga pedagoger är positit inställda till att lek och kopplar leken till den kognitiva utvecklingen..

AbstractThis report describes our ten week long thesis work which is the last task in our education in mechanical engineering at Linköpings University. The project has been performed at Siemens Industrial Turbomachinery AB?s service department. The company which is located in Finspång produces, sells and provides service for steam and gas turbines around the world.The purpose of this project is to help Siemens develop their maintenance programs for two of the auxiliary systems which are a part of the complete steam turbine system. These are lube and control oil systems.The project is restricted to two of Siemens maintenance products, No Stop Check (NSC) and the annual Safety Inspection (SI).

Eco certification of small housesTo construct an environmental friendly building and show that as a company you care for the environment, is presently very attractive in the Swedish real estate market.This degree thesis covers the environmental certification called ?Svanenmärkning? the Swan, witch is the Swedish equivalent to the European standard ?the EU Flower?. It is concentrated on the certification process in small houses that the Swedish institute of standard, SIS, has presented. We have worked together with the company Faluhus witch is a Swedish producer of small family houses.Faluhus is located in the town of Borlänge, Dalarna and has produced family houses since the 1950:s. They have a great heritage born in the old Swedish mining culture, with great wooden mansions and country homes.

This thesis has been conducted at Volvo Bussar ABunder a period of ten weeks. Within the organizationVolvo, the work is conducted with leaders and teamson every level; from production to top management.They have three tasks, besides executing their dailywork, they are expected to actively work on improvingtheir individual work as well as themselves as persons.The two latter are future value adding activities for theorganization. When doing so, however, it has beennoticed that they often lose the grasp of their dailywork. The question that consequently arises is whythis happens. Is it because of lack of time or it isbecause the co-workers do not have the competenceand simply do not know how they are to execute thethree tasks? Or, is it because the motivation to executethe three tasks is not enough? With this in regard, thestatement of issues for this bachelor thesis were thefollowing: how can the conditions for leaders and theteam be improved, in order for them to execute thesethree tasks.To find out why the execution of these threeassigments did not always succeed, the decision wastaken to conduct a survey and interview study in reallife and at the plants.

Problem: When opening a newspaper today there is a good chance that the headlines have something to do with recent developments in the global climate debate. This development is forcing companies to take action. The problem for many companies, including Thule, is that they are unaware of the environmental work conducted throughout their value chain and also what they need to do to become green. Thule, a company with a strong focus on profitability and growth, will not make environmental issues a part of their core strategy unless it can be shown that economic incentives exist. With this thesis we will try to build a case that will help Thule, and also other companies, see the possibilities a green venture brings with it.

Att beskriva en byggnad som tidlös är bland det finaste en kan säga. Några av världens mest uppskattade byggnader har beskriv- its som just det, tidlösa. Hur kommer det sig att en av den finaste komplimangen och erkännandet en byggnad kan få, egentligen är intetsägande? Tiden går ständigt och det finns ingenting någon kan göra för att ändra det. Människor, djur och även byggnader utvecklas och åldras.

The government regulations for energy use in buildings will be tightened in the future. At the same time the interest in environmental classifications and certifications of buildings is increasing. This has meant a new situation for solar energy. The designs of solar heating systems are often based on experience and/or rules of thumb, rather than calculations and simulations. This thesis examines whether simulation tools, in this case Polysun, are useful in this work.
