Alternativ uppvärmning av reningsverket på Utö - En studie av energibesparingsmöjligheterna i syfte att minska uppvärmningskostnaderna
The projects objective is to find an alternative method of heating (the current method being via electric heating) the sewage treatment plant on the island Utö in Stockholm?s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by ?Skärgårdsstiftelsen? (The Archipelago Foundation) and is a part of the larger EU-project ?Green Islands?.A model for the plants total heating demand is established in order to get a good perception of how much money can be saved using alternative heating methods. The heating demand model gives an annual heating demand of approximately 32 500 kWh and a maximum heating power demand of around 24,7 kW.
Torkning och pelletering av organiskt hushållsavfall - en konstruktionslösning
The research in this paper aims to producing a home version machine thatcan dry and make biological waste into compact pellets. This product ismade primarily for those who want to improve the environment and reducethe energy consuming process of separating the biological leftovers fromother waste in the large processing plants and save money due to reducedpickups of waste. Since there is no commercially available product thatdoes what we want to achieve we had to start from the beginning with boththe design and the mechanical aspects. The result is a machine, that fits inour homes, and in an easy and inexpensive way reduces the amount ofbiological waste that needs to be collected by the public wastetransportation system. This is done without reducing any of the energy inthe waste and it can still be used to compost or by large-scale plants that usethe waste to make electricity.
Visualisera elförbrukning med gamification
Problemet studien ställdes inför var att försöka lösa hur man med hjälp av gamification kan skapa ett användbart mobilt gränssnitt som visualiserar elförbrukning. Fallstudien har resulterat i ett förslag på hur man kan visualisera elförbrukning i mobila gränssnitt och med inslag av gamification. Resultatet har arbetats fram med hjälp av metodiken användarcentrerad design där användningstester och iterationer har utförts för att erhålla värdefull information från användare om hur de vill att en sådan här applikation ska se ut och fungera. Resultatet har sedan presenterats och analyserats utifrån den modell som togs fram från teorin. Resultatet är en interaktiv prototyp som vävt in teoridelarna användbarhet, mobila gränssnitt och gamification för att visualisera elförbrukning på ett användbart sätt..
Modellering, identifiering och reglering av skannern i ett laserbatymetrisystem
The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.
Varför ger våra givare?: en fallstudie om ideella
hjälporganisationers kartläggning av givare och deras motiv
The purpose of this thesis is to illustrate how non-profit organizations map the market of potential donors and how they apply their knowledge about the motives of the potential donors. The case-study of Church of Sweden Aid shows how a Swedish non-profit organization applies this in the daily work. In its strategic marketing the organization actively use marketing surveys in different forms. By employing an analyst Church of Sweden Aid has a possibility to make another step forward in order to understand its donor market and to adjust its strategic marketing plan to it. Church of Sweden Aid says that they don?t work with the donor?s motives.
Textlämplighet för dyslektiker? ? En studie av läroböcker som används i engelska A på gymnasiet
Syftet med den här studien är att undersöka textlämpligheten och dyslexianpassning av de texter som förekommer i svenska läroböcker i engelska A på gymnasiet. De läroböcker som undersöks är Master Plan, Straight Forward, RealTime1 och Spring Board 1. För att navigera rätt bland tidigare forskning och lärobokstexterna väljer jag att jobba utefter en frågeställning: 1. Vad kan ses som dyslexianpassning och vad är icke dyslexianpassning i läroböcker som används i engelska A? För att kunna undersöka textlämpligheten och dyslexianpassningen i lärobokstexterna användes två metoder; strukturell textanalys och innehållsanalys/läsbarhetsanalys. Resultatet av dessa analyser är bland annat att läroboken RealTime1 har stora fördelar för elever med dyslexi vad gäller textlämplighet..
Hur lagerhanteringssystem och artikelidentifiering kan bidra till logistisk effektivitet : En fallstudie på Nefab i Runemo
Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.
Product Return Process - Developing a Web-Based Return Form to Improve the Information Flow between an Apparel Company and Its Retailers
Handling product returns has become a critical activity for organizations as the volume of gods flowing back through the supply chain rapidly increases. Few research studies have published specific empirical data concerning the reverse logistics practices of companies. Information technology and information support has long been recognized as a competitive weapon ? capable of enhancing company performance and achieving efficient reverse logistics. Reverse logistics is very unlike the forward, as it is more reactive and also has less visibility.

Revisorns oberoende : en historisk skildring utifrån skandaler inom näringslivet
We have performed a historical research, trying to establish the auditing conditions, in terms of adjustments over time. Our purpose with this essay was to demonstrate the facts behind the independence of the auditor, and hopefully give the reader some new information.Our questions at issue were: What in the debate, regarding the independence of the auditor, in concern of the scandals, is most relevant each decade?Witch aftermath has influenced the regulation regarding the independence of the auditor?What we thought was the best way to answer this question was to study a large amount of journals according to the current decade, since 1930 and forward. The journals presented different persons opinions regarding the scandals, and we used them as an instrument to analyse the regulations and after-effects of the scandals.Our conclusion is that in purpose to make the auditor independent, the debate among competent and well-informed people in the line of business has, through the decades, frequently recurred to strive towards a more homogenous auditing..
Mikroproduktion av el : Micro-production of electricity
På elmarknaden har man utvecklat fenomenet mikroproduktion av elenergi vilket innbär att slutkunden själv ska producera sin el främst genom att utnyttja sol och vind kraft. I Sverige finns det ett växande intresset för mikroproduktion. De flesta som producerar sin egen el gör det främst genom solpaneler och mindre vindkraftverk som sätts upp vid deras egendom. I den här studien har vi gjort en djupare analys kring olika typer av anläggningar för att producera småskalig elkraft. Men även tittat på den ekonomiska aspekten genom att beskriva ekonomisk vinning och kostnader samt ställt upp en kostnadskalkyl för att beskriva detta i siffror.
Svenska fastighetsbolags resultat samt kassaflöde för och efter införandet av IAS 40
The connection between accounting and taxation goes back to the 1920s laws of the named areas. A proposal has now been brought forward, the so-called SamRoB-investigation, which means that the connection between accounting and taxations should be decoupled.The authors? aim with the study is to investigate what a possible decoupling between accounting and taxation, i.e. the formal connection and the untaxed revenues, implicates for the auditor´s work.A research has been done by interviewing two authorized auditors and one authorized consultant of accounting to get a view in how the auditor?s works could be affected.
Värmepumpars inverkan på elkvaliten
Modern technology and fast development of heat pumps, the hunt for savings in energy consumption and the strive for environmentally friendly energy sources, convenience, and financial profit, have made heat pumps a reasonable alternative for the heating of houses.When the heat pump starts it will consume a considerable amount of current, which may result in a short-lived voltage-drop if the power grid is weak compared to the start-up current.The company Fortum Distribution which owns and administrates electrical network is interested in an investigation that deals with heat pumps affect on the quality of electricity.The purpose of this investigation is to study fast electrical fluctuations (flicker) as a result of start-up currents for single as well as multiple heat pumps on the same electrical station and from this evaluate whether there will be any problems installing heat pumps..
