säkerhet inom 3G
Problem: Idag har de flesta detaljhandelsföretag någon form av kundklubb för att stärka banden mellan sig och sina kunder. Men skapar kundklubbar lojala kunder per automatik, eller krävs det mer än vad de flesta företag erbjuder idag? IKEA Family är en av de kundklubbar som funnits längst och på varuhuset i Älmhult upplever man inte att potentialen med kundklubben utnyttjas fullt ut då relationerna med medlemmarna inte utvecklas i önskvärd utsträckning. I detta arbete undersöks huruvida detta beror på konceptuella brister, val av strategi eller implementeringen av konceptet på varuhusnivå eller om det finns andra förklaringar. Syfte: Syftet med uppsatsen är att utifrån vår fallstudie på IKEA-varuhuset i Älmhult, samt med hjälp av utvalda teorier kring lojalitet, relationsmarknadsföring och strategi, skapa förståelse för hur en kundklubbsstrategi bör utformas och förverkligas samt visa på vilka problem som kan uppstå.
Effektivisering av kravspecifikationsprocessen
The goal of this project was to make the requirement process at the Swedish
Coastguard more effective. The first step to achieve this was done by locating
bottle necks in the process with value stream mapping method. The result of
this study showed that the biggest restriction in the requirement process was
while examining older requirement documents to understand what elements were
suitable for the particular project.
This was followed by a study of literature, interviews and theory of Lean
Production with the ambition to investigate how the requirement process was
handled on other companies and how to improve the process on the Swedish coast
guard. This led to a number of potential enhancements of the process which
later was evaluated.
Requirements written by different people in different organizations were
analyzed in order to sort out if there were some similarities? which could be
used as standard elements in a future standardization of the process.
Varför använder sig svenska industriföretag av trådgnistning? : ? en studie av de praktiska fördelarna med bearbetningsprocessen
Trådgnistning (på engelska Wire Electrical Discharge Machining eller WEDM) är en termiskbearbetningsprocess för att med en trådelektrod skära i elektriskt ledande material. Metoden har teoretiskt sett många fördelar och relativt få nackdelar. Intervjuer i studien visar att trots detta så undviker flera industriföretag om möjligt denna process. Syftet med studien är att utifrån de teoretiska fördelarna som anges i litteraturen undersöka vad företag i Sverige anser vara de mest relevanta praktiska fördelarna med trådgnistning som bearbetningsprocess. En internetbaserad enkät har skickats ut och besvarats av 20 industriföretag runtom i Sverige.
Utveckling av minimax-baserad agent för strategispelet Stratego
Stratego is a boardgame not very different from chess, that contains hidden information. Because of this, existing programs play at beginner level. The purpose of this thesis is to adjust a minimax algorithm so that it passes the demands of Stratego, and then build a Stratego agent around it. Tests with existing minimax algorithms leads to the development p-e-minimax. This algorithm uses two different values in its nodes to simulate the different information available to the agent and its opponent.
C# - Framtidens språk???
This paper is about the new programming language from Microsoft, C# (See Sharp)
and the
.NET Framework. They are still in beta-version, but will be released on the
market in
February 2002. This paper presents C#, not in detail but the characteristics
that distinguish the
language. A comparison is done with C++ and Java, since C# is most resembling
to these
languages. Both C# and Java have been developed from the mother- language C++.
Standardisering och kalkylering av maskinhallar
This thesis has been carried out onbehalf of Lindborg & Sons in Örsundsbroand is a concluding part of the Bachelorof Science program in ConstructionEngineering at Uppsala University. Theaim of the project is to make a plea fora database of good examples of themachine room types using Revit drawingprogram, and work out a correspondingworksheet .At the start of the process it becameapparent that there were somedifficulties in using Revit to creatingmachine room types of the variety whichthe company builds. For modelling ofoblique, curved and irregular lines, Ihad to use my AutoCAD Architecture andthen import them into Revit.The creation of calculus in Excel wastime consuming. On the other hand, it isa one-time work to create the template.The advantage of Excel is that there isno need for a re-calculation at the costof various types of machine hall. Allthat is needed is to replace the variousparameters.
En kvalitetsbedömning av några av flygvapnets kravunderlag
Uppsatsen undersöker inledningsvis om FOI:s principer för kravformulering kan anses behöva kompletteras mot bakgrund av Försvarsmaktens behov och undersöker därefter kvalitén i några av flygvapnets kravunderlag relativt principerna för kravformulering. Av resultatet framgår att principerna kan behöva kompletteras med principerna prioritering och kontextuell beskrivning. Av fallstudiernas resultat framgår att kvalitén i flygvapnets kravunderlag relativt principerna för kravformulering generellt är låg, att den varierar mellan underlagen och att den i vissa fall är mycket låg i fråga om uppfyllnad av principerna. Uppsatsen rekommenderar att FOI:s principer för kravformulering utökas med principerna prioritering och kontextuell beskrivning. Vidare rekommenderas flygvapnet att öka kvalitén i framtida kravformuleringarna så att den militära nyttan av arbete med kravformulering även kan öka.
Undervattensvågbrytare - En modellstudie
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Utveckling och tillämpning av modeller förkvantifiering av de ekonomiska konsekvensernaav ökad förbrukningsflexibilitet inom eldistribution
One step towards a more sustainable energy system is to create a more flexible electrical grid, where increased demand response among electricity consumers can play an important role. A distribution grid owner can encourage their customers to use electricity more evenly distributed during the day by introducing different types of grid fees such as time-differentiated power tariffs. In this master thesis, the theoretical economic impact of a flattened load profile for a distribution grid owner is investigated. Different factors that impact the distribution grid owner?s economy are identified and two are chosen to be quantified; losses in the grid and the fee to the feeding grid.

But then small changes in themodel could have major economic consequences.The thesis has generated results that show common weaknesses among the variousprojects and their project managers' general opinions about the project model. It alsopresents some possible solutions based on own thoughts and those interviewedobjects suggestions and comments..
Inneluftsventileradekryprumsgrunder : en utvärdering av två tillverkare
This Diploma work investigates internal air ventilated crawl-space in respect to construction and damp. The Diploma work assumes from a general description of crawl-space and general dump problems in ground construction. An internal air ventilated crawl-space is a construction where you take the ventilation air from the building and bring it down to the crawl-space and lets the air circulate before it passes through a retaining aggregate on the way out from the crawl-space. In this matter you get a worm space under the building and a lot less dump problems in form of · Ground damp · Build damp The ground dump reduces through draining around the building, different layer of gravel between the ground and the building and ventilation of the crawl- space. The build dump reduces through ventilation of the crawl-space as fast as possible.
Storleksoptimering av en etanolfabrik för integrering med ENA Energis kraftvärmeverk. : Baserat på en regional energibalans mellan tillgång på etanolbränsle i Enköping kommun och producerad etanol med hjälp av tillgänglig ånga från ENA kraftvärmeverk.
AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power. ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant. As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol. Etanolens framtid vilar på bra lösningar för framställning. I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle. Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

Investeringskalkyl baserad på ett flerbostadshus energiprestanda
The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..
