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.

Promenadstaden : dess betydelse för Stockholms möjlighet till en ekologiskt hållbar utveckling

It is a well known archaeological concern that the remains of human bones left from the bronze age and early iron age Scandinavia are not nearly enough to represent the estimated population of the time. Furthermore the bones of each find rarely represent a whole individual. The majority of the bones must have been disposed of somewhere else, possibly scattered in running waters or in the fields, where they have evaporated or are securely hidden from archaeological excavations.This thesis deals with the grave concept and the problem in using a word that is so very clouded by its modern, western meaning. It also offers an alternative explanation to why the bones are handled the way they are and why they are found in such awkward contexts..

Examinerade Sjöingenjörer : En fallstudie kring deras första anställning

Efter att ha fått en Sjöingenjörsexamen och samlat ihop alla certifikat som behövs står studenten färdig att arbeta som vakthavande maskinbefäl på fartyg. Frågor som individen ställer sig själv när han/hon står där, redo att påbörja en ny fas i sitt liv är frågor såsom: Var skulle jag vilja jobba?, När får jag ett jobb? och Hur skaffar jag mig ett jobb? Syftet med denna studie är att försöka skapa en bild av hur det har sett ut de senare åren för examinerade sjöingenjörer från Kalmar Sjöfartshögskola att komma ut på arbetsmarknaden.Metoden som användes var i form av ett frågeformulär som skickades ut till tidigare studenter som tog examen från Kalmar under åren 2009, 2010 och 2011. De gavs möjligheten att svara på en webbenkät eller att svara på en postenkät som skickades till deras folkbokföringsadresser.Studien innefattade totalt 36 personer, varav 20 personer valde att delta. Resultat från studien visar att av de 20 personer som valde att delta hittade samtliga personer arbete till sjöss.

Energikonsumtion hos en diskmaskin

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

Bullertunneln : En utredning kring en ny bullerlösning vid trafikleder

The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof ? like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and barrier effects. This project idea is called the Noise tunnel.After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction ? at least not when government regulations of acceptable noise levels are applied.

En tung börda på amfibieskyttesoldatens axlar? : Eller har rörligheten varit prioriterad?

Bakgrunden till studien är att vikten på den enskilda soldaten ökar allt mer vilket reducerar rörligheten. Om soldaten bär för tungt ökar risken för att verkan inte kan avges på rätt plats i rätt tid på grund av minskad rörlighet. Terrängen som amfibiesoldaten verkar i medför att stor del av striden sker till fots vilket torde betyda att rörligheten borde vara prioriterat för soldaten. Syftet med uppsatsen är att undersöka om rörlighet har varit prioriterat, för en amfibieskyttesoldat när den bedriver strid till fots, gentemot vikten på och plutonens anpassning av verkans- och skyddsutrustning. Metoden som använts är en jämförelse mellan amfibieskyttesoldatens olika utrustningsalternativ med de vikter som fastställts i författarens analysverktyg som utgår från de amerikanska doktrinerna.

Modernisering av en fotbollsarena : Örjans Vall

The purpose of this study is to show the technical building requirements for modern arenas inSweden. The study will also create an understanding of how the requirements affect theSwedish football arenas which are affected by the regulations valid from 2014. As one of theSwedish football arenas there is Örjans Vall located in Halmstad. The aim of this study is todevelop alternative solutions regarding the technical problems Örjans Vall is facing 2014,when the new arena requirements for ?Svensk elitfotboll? are taken into use.

Preferensaktier och obligationer som fastighetsfinansiering

The recent turbulence in the financial markets has contributed to the banks becoming more restrictive to lend to real estate financing. Deleveraging in Europe's banking sector has also contributed to banks reducing their leverage and increasing capital adequacy to meet the new requirements. Loan-to-value ratios in real estate loans have fallen while banks' interest margins have increased, which has made property investors to look for alternative sources of funding in the capital markets. The two most interesting forms of financing for real estate right now is bonds and preferred shares as they fit property companies that generate stable and predictable cash flows. A bond is an interest-bearing debenture certifying that the purchaser has lent money to the company that issued the bond.

Wobblerpump

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

Beräkning av värmeenergiförluster i flerbostadshus genom analys av den totala fjärrvärmeenergianvändningen :

This thesis has been carried out on behalf of IV Produkt AB and intends to set an average ratio of thermal energy losses in apartment buildings that were built during the 1960-1990. This shall be derived by analyzing the total district energy consumption that has been divided into three parts: heat energy losses (the actual heating requirements), the heating of domestic hot water and heating energy consumption for the controlled ventilation.Three different residential areas that were built during the years 1962-1966 and one that was built in 1993 has been analyzed. All residential areas are located in Växjö urban and contains between four and six apartment buildings.The analyzed objects have a mechanical exhaust ventilation systems and district heating as the heating method. No own laboratory work or experiments have been done in this thesis, the calculations have been done on the basis of parameters from VEAB, interviews with property managers, and literature studies. By calculations, we have got a result that is reported in Chapter 6.

VTA-aggregatet : En undersökning av driftegenskaper och funktion vid slowsteaming.

Turboaggregat med variabel geometri har länge funnit hos automobiler, men det dröjde ända tills 2008 innan det första dök upp på ett fartyg. Syftet med denna undersökning har varit att kontrollera om de fördelar som Man B&W hävdar att VTA-aggregatet skall ha stämmer, samt att undersöka om VTA-aggregatet kan lösa de problem som uppkommer i och med att man kör med reducerad fart, s.k. slowsteaming. För att undersöka detta har jag bedrivit litteraturstudie, med insamling av data mestadels från Internet.Resultatet av undersökningen visar på att ett VTA-aggregat kan minska bränsleförbrukningen och vissa emissioner vid reducerad fart jämfört med en konventionell turbo av samma storlek. Den minskade bränsleförbrukningen leder i sin tur till ekonomiska vinster.

Bäddodling av matpotatis :

This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes. Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient. In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.
