Hallbyggnadsteknik - en effektivisering av småhusproduktion
Syftet med det här examensarbetet är att undersöka om det är möjligt att överföra hallbyggnadsteknik till produktion av småhus för att sänka produktionskostnaderna. Studien visar att hallbyggnadsteknik enkelt går att överföra till en villa. Dessutom blir det billigare att bygga klimatskalet med vårt byggsystem jämfört med ett traditionellt prefabricerat småhus. Genom detta system kan den totala byggkostnaden för villan i jämförelsen sänkas med 3-10 % beroende på vilket fasadmaterial som väljs..
Hållbara uppvärmningsalternativ för Grinda Wärdshus : En studie om uppvärmning med pellets och flis
This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating system. The aim of this thesis is to investigate whether wood chips or pellets is, from a sustainability standpoint, a suitable heating method for the guest house.
Biologisk bekämpning av Fusarium graminearum
Fusarium graminearum causes reduction in both yield and quality in cereal grain worldwide. One of the diseases it can cause is Fusarium Head Blight (FHB). Both sexually and asexually produced spores can infect living plants. Asexual conidia are produced in the mycelium while sexual ascospores form in asci in perithecia on debris. In biological control, living organsims are used to control pests and diseases.
Upprättande av mall för fuktsäkerhetsbeskrivning : Genom granskning av projekt ur fuktsäkerhetssynpunkt
During the 1990?s a large number of building projects were revealed where lack of moistsafety precautions during the construction process had led to extensive moisture damage. Alsoresent implemented studies have shown that the problems with moisture damages have ratherincreased than decreased during the past few years. Moist is considered to be one of the mainfactors to cause unhealth due to deficiencies in the indoor-environment and does also causeunnecessary expenses and a reduction of the confidence in the construction industry.In this Bachelor of Science thesis three projects have been reviewed to examine how moistsafetyhas been observed during the construction process. Main focus has been to identify thebuilding components that are the most exposed to moist, and to examine how they have beentaken into account during the period of design and construction.
Limträstomme till hallbyggnader : Utformning och dimensionering av momentstyva ramhörn och 3D-modell framtagning
Industrial buildings are increasing all over Sweden. Farmers are building new modern facilities and the government chooses to build new halls to invest i youth sports. Glulam is the most common framework but there are limitations because of the transport. Therefore, there is a need to develop new solutions to increase the use of glulam.The maximum torque in the eaves was found in the frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated.
Naturens p?verkan p? elever i skolan: En forsknings?versikt ?ver hur biologiundervisning utomhus p?verkar elever med fokus p? intresse
In the Western world the interest in science in schools is steadily declining. Focusing on
interest is important to encourage students to lifelong learning which is a written purpose of
the Swedish curriculum. This literature study examines if biology education outside in nature
could be a part of the solution for this problem and the question of issue is how can education
outdoor enhance students? interest for biology and what other aspects does this effect
simultaneously? The method of block search was selected for addressing this question,
utilizing the ERIC and ERC databases. The results show that situational interest increased
with outside education due to aspects such as: novelty, hands-on, knowledge acquisition and
social interaction.
Systemlösningar för plus- eller passivhus : En studie med syftet att lösa energibehovet för ett specifikt hus.
The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.
Toleransproblem vid produktion och montering av prefabricerade betongelement
The idea with constructions made out of prefabricated elements is that it should be quick and easy to build as the demands for lower production costs, increased profitability and shorter production times are constantly increasing. High accuracy in measurements and well-balanced tolerances is required to achieve this. The fact that the concrete-elements doesn?t fit and that damage occurs during assembly is a highly topical issue even though we now have methods and systems that make this high-intensity construction possible. Through this report we want to highlight the problems that cause the dimensional and tolerance problems and give suggestions on how to come to terms with these.

Bachelor thesis, Controller, Program of Master of Science in Business and Economics, School of Business and Economics at Linneaus University in Växjö, Sweden, Course Code: 2FE13E:3, Spring 2012 Authors: Jacob Cedergren, Adam Pettersson, Hampus SkelterwijkSupervisor: Anders JerrelingTitle: The ERP-systems impact of the management control - a case study of VIDA AB Original Title: Affärssystemens påverkan på ekonomistyrningen - en fallstudie på VIDA ABBackground: New technology has given businesses new opportunities to use and store information and the current information systems has changed the way of working in more or less all sectors and operations. ERP-systems have been one of the most important IT innovations in the past decade. The potential of a properly implemented ERP-system is great because it has got the ability to link the company?s different areas together. Despite its many advantages, there are several examples of cases where the acquisition and implementation has been a total failure.
Valsningsteknik för extremt höghållfasta tunna stål
New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.

Dämpning av fläktljud i diskmaskin
Detta examensarbete omfattar akustiska undersökningar utav en desinficerande diskmaskin av typ Getinge 8666/8668 och har utförts på Getinge Desinfection AB i Växjö. Vi har undersökt hur man med enkla medel kan sänka ljudtrycksnivån i maskinens närhet. Mätningar har utförts på diskmaskinens torkprogram, där torkfläktarna är de mest dominerande ljudkällorna och ljudet främst är luftburet. En systematisk analysmetod bestående av införandet av successiva dämpningsåtgärder visade att de dominerande ljudvägarna går via taket, golvet samt till viss del spalter i maskinens väggar. Genom att isolera både tak, golv och spalter kunde ljudtrycksnivån sänkas med totalt hela 5,9 dB.
En plats att bo på? : hyresnivåernas nivåfluktuationer 1999 - 2007
The purpose of this paper is to present and analyze the yearly expenses for Swedish rental apartments during the period 1999 to 2007. At the end, it will give the reader a general picture of how the cost-level has fluctuated depending on the production year when the apartment building was finished, and where the same building is located. This paper has the following questions as a starting point:- Can there be an identification of regions depending on where people tend to favor renting an apartment?- How are those regions distributed? That is, where are the cost-levels of the yearly rental expenses highest and where are the levels lowest?Nine statistical surveys from the Swedish government agency Statistics Sweden (Statistiska Centralbyrån) have been used as primary sources for this paper. These surveys deal with price pictures of housing in general, but for this paper the only information that has been used is the one about rental apartments.
