Byggbranschen är inne i en övergångsfas mellan 2D och 3D. BIM, som arbetsmetod, och 3D-modeller blir allt vanligare. I broprojekt är dock efterfrågan på dessa modeller låg. På WSP i Stockholm används 3D-modelleringprogrammet Tekla Structures i stor utsträckning på flera avdelningar. Önskemål finns om att utöka användningen av programmet även inom broprojektering.

Målet med detta arbete är att undersöka och analysera en byggnad från miljonprogrammet i Helsingborg göra gällande energiberäkningar. Dessa beräkningar ska mynna ut i olika förslag till hur man skulle kunna styra upp en renovering av dessa byggnader så att de uppfyller de nya energikraven samt skapa en mer tilltalande estetisk byggnad..

AbstractThe Energy Declaration is a law that will come into effect October 1: Th 2006. This report has Värnamo municipality as principal and shall clarify what the estate owner in general and Värnamo municipality in particular need to know about this law. Another part that is going to be dealt with is how large the future need for energy experts in this field will be, and which competence that will be demanded for them.The work will in general deal with simplified energy declarations for apartment houses and public buildings, since these buildings are the first to be involved with energy declarations.The energy declaration will consist of a number of important components.? Energy power i.e. how much energy the building consume? If the ventilation control is done? If the radon measurement is carried out? Recommendations of measures to improve the energy power? Reference value to compare the buildings energy power againstAccording to the law the declaration shall been made by an independent expert, which will need certain information for this.

This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).

I arbetet görs ett försök att genom litteratur och elevintervjuer närma sig frågan om vilka förutsättningar för lärande som simuleringar i geografi erbjuder och vilka lärandeteorier som då blir relevanta. Intervjuer har därför gjorts med elever efter att de genomfört ett för undersökningen utvalt simuleringsspel. I arbetet ställs också frågan om hur elever uppfattar simuleringen som didaktiskt verktyg och ett antal svarskategorier struktureras. Slutsatserna är att lärandet i simuleringar i första hand tycks vara beroende av den egna praktiska erfarenheten, den sociala interaktionen mellan deltagarna och den emotionella laddningen. Elevernas uppfattningar av lärandeformen stödjer dessa kvalitéer, men tillfogade också betydelsen av variation i undervisningen och det inneboende spelrummets betydelse för kreativiteten..

TCP (Transmission Control Protocol) is a transport protocol designed for the wired Internet. In wireless networks packet losses occur more frequently due to the unreliability of the physical link. The main problem is that TCP treats all losses as congestion, which leads to a lower throughput. Ad hoc networks are multihop wireless networks of mobile nodes, where each node can allow other packets to pass through it. Topology changes often occur and may lead to packet losses and delays, which TCP misinterprets as congestion.

This report deals with the design of a controller for SmartMedia? flash memory cards, based on a hardware description found in the SmartMedia? Interface Library - SMIL. The design was made on logic gate level, using standard cells in OrCAD Capture. After simulation of the design in PSpice A/D, it was exported as an EDIF netlist, which was used to make a chip layout in L-Edit, a layout tool for making integrated circuits. The layout was made using a method called Standard Place and Route - SPR, where the layout tool places standard cells from a library and connects them according to the EDIF netlist.

As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.

This project is about Jönsaplan in Landskrona. Jönsaplan is situated at the center of Landskrona in a part called Södra centrum which the municipality is developing, mainly by building new residential buildings. Today, Jönsaplan is not a functioning square. This is due to a ferry terminal and its many fences that block the way for people. In this project, I have assumed that the ferry terminal will be moved somewhere else so that Jönsaplan can be a real square. By studying The Concise Townscape by Gordon Cullen and Byens uttrykksformer by Thomas Thiis - Evensen and three reference places, Daniaparken, Raoul Wallenbergs torg and Norr Mälarstrand, I came up with a number of guidelines for my design proposal for Jönsaplan.

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

This thesis considers the use of an oldrock cavern as thermal energy storage.With a large system of differentchillers a model was created to find anappropriate future system. There aremainly two trajectories to take. Eitheran installation of chillers needs to bemade or the rock cavern can be used tomeet the future demand of districtcooling in Solna, Sweden. Additionallythis thesis investigates the possibleuse of different techniques to utilizethe phase change energy of water.Simulation shows that it?s possible toutilize the phase-change energy of afluid; however it?s not economicallyfeasible due to the thermodynamiceffects on the Carnot cycle.

How does IT-consultants reason in their consulting process regarding the development of a clients IT-based internal recruitment system? The purpose with this paper is to investigate how an IT-consultant is reasoning in a consulting process and investigate whether consultants are using established models and methods in their work. We have chosen to work with a qualitative examination to attain our purpose. In our work gathering the empirical facts we have been working with a case study, an observation and a simulation exercise. The combination of these has made it possible to carry out the paper and produce the most correct data possible.

Detta examensarbete utreder möjligheterna att utveckla en energieffektiv luftningsstrategi i en aktivslamprocess. Arbetet innehåller först en litteraturstudie där forskningsläget gås igenom.Därefter följer en optimeringsstudie i Matlab, en simuleringsstudie i en förenklad variant av Benchmark Simulation Model No 1 (BSM1) och en redogörelse för ett fullskaleförsök vid Käppalaverket.  Resultaten från optimeringsstudien visar att, under vissa förutsättningar, är ett konstant luftflöde energioptimalt. Simuleringsstudierna visar att en minskning av energiförbrukningen på upp till 16%  kan uppnås, då luftflödet hålls konstant, jämfört med att hålla ett konstant ammoniumbörvärde. Preliminära resultat från fullskaleförsöken indikerar att ett konstant luftflöde kan minska luftförbrukningen men en längre utvärdering bör genomföras för att få mer tillförlitliga resultat.Slutsatsen från detta arbete är att den utvecklade metodiken kan vara intressanta alternativ till en överordnad reglering av ammoniumkoncentrationen och bör därför studeras vidare..

Förståelsen för andra människor som krävs för lyckade interaktioner, förklaras i attributionsteorierna "Theory of Mind" och "Simulation Theory. Ett vanligt men ouppklarat fenomen är det fundamentala attributionsfelet, där beteende felaktigt attribueras till inre generella egenskaper. Fenomenet reflekterar en abstrakt mental konstruktion i enlighet med Construal Level Theorys antagande om hur psykologisk distans inverkar på perception. I en modifierad Attitude Attribution Paradigm modell undersöks om spatial distans påverkar det fundamentala attributionsfelet och om skillnader föreligger mellan kvinnor och män. Kort/lång spatial distans primades genom en kontroversiell text, via information om dess kompositionsplats, som fungerade som underlag för bedömning av skribentens åsikt.
