Svenska i enlighet med skolans värdegrund?
This study aimed at supplementing the Swedish National Agency for Education?s (Skolverket) study (2006) I enlighet med skolans värdegrund? which investigated whether textbooks in various school subjects went against the fundamental values in the curricula Lpf94 and Lpo 94. Due to this study?s supplementing intention, this study uses a similar title as Skolverket. By adding a new subject (Swedish) to Skolverket?s study, this study also strived to show how discrimination might be present in other subjects than the ones Skolverket involved in their study.
Analys av dricksvattenrening med metoderna Mikrobiologisk riskanalys (MRA) och God desinfeksjonspraksis (GDP)
Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.
Användning av förstapersonsspel vid militär simulering av strid i bebyggelse
The goal of this master thesis is to show the benefit of using computer games of the type First Person Shooter, FPS in the field of military simulations. The main focus in this is around a couple of topics. Creating the AI that controls the behaviour of the computer-controlled characters, the bots. Create an environment where it is possible to supervise the bots and also design a framework that enables cooperation between a group of bots, a squad. The result is Total Unreal Studio, TUS, a program where it is possible to add bots to a squad, connect them to a game server and inspect what the bots are doing.
Energikartläggning av polishuset i Gävle : Åtgärdsförslag för ett minskat energibehov i fastigheten Gävle Söder 17:10
The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.
Osäkerhet i energisimuleringar av flerbostadshus : Analys av fem nybyggnationer
Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.
Re-design av BEV-heater
Denna rapport beskriver det examensarbete som utförts på Calix AB under vårterminen 2013. Calix AB tillverkar värmare för bland annat batteri och kupé till fordonsindustrin. Uppdraget i detta examensarbete var att göra en omkonstruktion på BEV-heatern (Battery Electrical Vehicle) som är en batteri- och kupévärmare till el och hybridfordon. Problemet med den nuvarande konstruktionen är att den bygger på delar från äldre värmare till fordon med förbränningsmotorer, samt att konstruktionen inte är lämplig för produktion i större serier. Krav som Calix AB hade var:Integrerat ChassiMinimera tryckfallUnderlätta montering och tillverkningUppfylla standarder satta av fordonsindustrinKunna monteras ?in-line? i fordonetFör att kunna genomföra projektet var vi till en början tvungna att få kunskap om hur den befintliga BEV-heatern fungerar.
Optimering av slutfasstyrning
Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.
Studie av värmeflöden i befintligt bostadsbestånd : Utvärdering av energieffektiva besparingsåtgärder
The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.
"Det känns ganska fräscht att ha en Volvo för att nu har ju dom den i Solsidan" : En kvalitativ attitydundersökning om svenska tv-tittares attityd till produktplacering
Since product placement is a relatively new phenomenon in Swedish television, there is a lack of research on what attitudes Swedish TV-viewers hold towards it. This is where our paper will contribute to the research. The purpose of this reserachpaper is to describe and analyze what attitude Swedish TV-viewers has towards product placement. Kim Schröders multidimensional model of mass media reception were used, which is a developed model from Stuart Hall?s ?encoding/decoding? one-dimensional model.
Kartläggning av material flödesflaskhals i ICA butik.
In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.
Virtual Reality : En ny veklighet för arbetsterapin?
Arbetsterapi är ett ämne som framhäver hälsa och välmående genom aktivitet. Det huvudsakliga målet som arbetsterapeut är att möjliggöra för personer att delta i aktiviteter i det dagliga livet. Virtual Reality är en simulation där datorgrafik används för att skapa en tillsynes realistisk miljö och denna värld är inte statisk utan integrerar med användaren. Syftet med denna litteraturstudie är att kartlägga hur och varför Virtual Reality kan användas av arbetsterapeuter. En systematisk litteraturstudie genomfördes och efter databassökning uppkom 14 artiklar som via en manuell sökning kompletterades med ytterligare 5 artiklar.
Modell för dimensionering av AGV-system inom tung industri
Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.
Design and evaluation of an AGV-system for Tetra Pack in Lund using simulation
This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.

Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.
Borta med vinden : skogsägares erfarenheter av avverkningstjänster efter stormen Ivar
Hösten 2013 stormade det i Sverige ett flertal gånger. En av dem, stormen Ivar, fällde 4,3 miljoner skogskubikmeter privatägd skog med kärnområde i Medelpad och Jämtland. De senaste åren har varit stormtäta och en mängd erfarenheter finns från att hantera stormarnas konsekvenser. Dock saknas forskning om hur skogsägarna resonerar efter en storm och upp-lever de stormtjänster som erbjuds, vilket lade grunden för detta examensarbete. Syftet var därför att ta reda på och förklara hur skogsägarna upplevde stormen Ivar från stormtillfället till nästan ett år efter stormens framfart, vad som påverkar den upplevda tjänstekvaliteten och hur framtidens stormtjänst bör se ut.
