Resurseffektiv livsmedelsproduktion : Tillämpning av industriell symbios för ökad resurseffektivitet inom den svenska tomatodlingsbranschen
Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.
Energieffektiva principer : Påverkan på en villas arkitektur och energiprestanda
Kraven på att nybyggda bostäder ska vara energisnåla i driftskedet ökar hela tiden av flera anledningar. Dels vill brukarna hålla driftskostnaderna så låga som möjligt och dels är det miljöaspekten som spelar in. Men hur energisnål kan en villa egentligen göras och hur påverkas arkitekturen då den görs extremt energieffektiv?I den här rapporten utreds tio energieffektiva principer som kan användas för att göra en villa mer energisnål och energiproducerande. Alla tio principer har tillämpats i en villa som projekterats under arbetets gång.
LEAN produktuveckling : Ett arbete om kunskapsbaserad produktutveckling med fokus på tvärfunktionellt samarbete & lärande
Lean Product Development is a knowledge-based business concept in order to maintain high quality, meetcustomer requirements and to make product development more efficient. An important part of the processis to add a lot of resources at an early stage and execute the development as an iterative process betweendepartments exploring many alternatives thoroughly. The work focuses on how Lean ProductDevelopment is carried out and explores how to manage interaction between different departments andexpertise with regard to cross-functional collaboration and knowledge sharing i.e. learning.The information for the studies was gathered at a major Swedish company from two projects. The projectswere carried out as cross-functional and possible key factors for cross-functional collaboration wasidentified.The results have been correlated with theories of Lean, Product development, Lean product developmentand Learning.
Att motivera med belöning : En studie av attityder och beteenden på ett företag i hemelektronikbranschen
The underlying question addressed in this paper is whether or not it is possible to influence the way a company?s employees behave using monetary incentives. How efficient is money as a means to enhance work motivation? Today, the assumption that employees perform better when bribed with rewards is questioned by scholars. The previous confidence in monetary reward systems is increasingly being replaced with hope for more effective programs, where employees to a greater extent can be motivated by non-monetary incentives.
Renovering av miljonprogrammet till Umeå kommuns nybyggnadskrav för energianvändning
A lot of houses built during the Million Homes Programme are in need of major renovation. Today?s technology and materials are better than in the 60?s and 70?s. Both Swedish government and the European Union have set climate goals regarding energy consumption by 2020 and 2050. Achieving these goals would require better standards in buildings than the Building regulations demands, such as Umeå municipality?s construction requirements for new buildings.The report aims to investigate if a renovation of apartment buildings from the Million Homes Programme can reach Umeå municipality?s construction requirements.
Nyanlända flykting- och invandrarbarns skolintroduktion : En jämförande studie om två skolors arbetssätt
The objective with this study is to investigate the school introduction of newly arrived students, by focusing on the latter years of high school, by comparing two schools method of working.This was done by a qualitative survey based on half structured interviews and existing school documentation.The questions of the study targeted the schools method of working, how well the education was adapted to the students and if it was appropriate to them. We also asked about the school resources to meet the need of the newly arrived students. Our theoretical assumptions were based on Haugs? terms ?including integration? and ?excluding integration?, Lahdenperäs? theory about intercultural education, Vygotskijs thoughts about adapted education and finally Blossings? description of different cooperative cultures. Our results showed that school introduction for newly arrived students were formed from the schools? view on learning development and adapted education.

Värmeåtervinning på förskolan Rymdattacken 1 : En jämförelse av värmeväxlare
In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.
Luft/luftvärmepump : - Med möjlighet till återvinning
Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.
Projektledning inom mjukvaruutveckling : En studie om betydelsen av teknisk kompetens utifrån projektmedarbetares perspektiv
More than half of the implemented IT-projects go over budget, deadline or simply fail. The processes in an IT-project requires technical competence to be present among the project participants to ensure the achievement of business goals and to make organisations competitive. The success of an IT-project largely depends on the project manager which makes it interesting to further investigate what impact the project manager?s technical competence has on the project. Previous research shows differing opinions whether technical competence is considered important for the project manager to be successful or not.
Materiallogistik vid innerstadsprojekt : En fallstudie av ett innerstadsprojekt i förbättringssyfte av materialflödet
The construction industry is always looking for ways to make the work more efficient aswell as minimize the waste of money in general. At the same time the industry is showing alow awareness of logistics which has to increase in order to improve the industry in thesekind of questions. Projects located in the inner city have high demands on the logistic andthe handling of material due to the so often limited space for storages of the material. Dueto this the purpose of this report is true a case, study and analyze what kind of factors thereis to take into consideration during the materials way from the supplier to the workstationin a project located in the inner city. The data for the report was collected with the help of acase study, and in three different ways.

Trådlös kamerastyrning
As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.
Hästhållares uppfattning av Länsstyrelsens tillsyn i Halland
In the beginning of 2009 The County Administrative Boards assumed the responsibility of animal welfare, a task previously performed by the individual municipalities. This transfer was made with the aim of achieving more efficient and equivalent animal welfare controls across the country. Previous studies among animal owners have shown a somewhat negative image of animal welfare controls. This study focuses on investigating the experiences of the horse keepers in the County of Halland concerning animal welfare. The study is based on a questionnaire which was sent to 423 horse keepers in Halland, of which 130 were returned with information that laid the foundation of this study.
Hur ska du investera dina PPM-pengar? : En studie om PPM-fondernas historiska avkastning
Purpose: The main purpose of this study is to study the 45 funds, divided into three differentdivisions, then the result will provide a greater understanding of how returns change with ahigher risk.Methodology: The study is based on a quantitative approach. The survey was conducted bygathering raw data from databases and secondary data from literature, printed and electronicsources.Theoretical perspectives: The study is based on the theory: the efficient markethypothesis, which argues that future returns can not be calculated as the market is fullyinformed. The study is therefore studying historical yields.Empirical foundation: Empirical data are acquired from www.morningstar.se, andtherefore also treated on this page. The material is then divided into documents and time axes.Conclusions: The study has shown that high-risk funds give a higher percentage returns thanmedium-and low-risk funds. However, does not imply a higher risk automatically earn ahigher return when the low-risk funds have shown a higher yield than medium-risk funds.
