Tredimensionell sensorscanner
This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..
Webbsystem för matprisjämförelser
This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
Det Intelligenta Huset : - En studie i hemautomation
Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.
"Asiaten" - en pandemi gör entré - En diskursanalys av två dagstidningars rapportering kring den asiatiska influensan 1957
Syftet med föreliggande studie är att utifrån nyhetsrapporteringen i Ystads Allehanda och Sydsvenska Dagbladet Snällposten undersöka vems röster som gjordes hörda i den massmediala diskursen kring den asiatiska influensan som grasserade 1957. Utifrån olika teman, som jag vid närläsningen kunde identifiera som återkommande i nyhetstexterna, studerar jag vad man talade om och hur man talade om detta. Jag studerar också vem mottagarna var och om det förmedlas några speciella budskap. Dessutom gör jag en jämförelse av de båda tidningarnas rapportering i egenskap av att SDS kan sägas representera stad medan YA representerar landsbygd.
Undersökningen genomförs med utgångspunkt i Faircloughs kritiska diskursanalys och utifrån det teoretiska perspektivet att språket i sig är en handling. Vad som förmedlas via språket är ingen avspegling av verkligheten, utan en konstruktion, som utifrån olika perspektiv och syften skapar ?sanningar?.
Ledarskap inom ramen för ett systemutvecklingsprojekt - fokus på en arbetsprocess med stöd i Vattenfallsmodellen
Many research reports mention the fact that a huge number of all system
development projects never reach a successful ending; with other words never
fulfil formulated goals. By identifying and forming success factors (and in
some aspect risk factors) that the project manager in practice can use, this
study may be seen as a step in the direction towards minimising the high number
of failed system development projects.
The purpose of this research report is to investigate how a system development
project, where the development process is based on a specific development or
process model (in this case the Waterfall model), can and should be driven. I
aim to clarify what is demanded of a project leader for the specific
development process and give an account for which eventual leadership qualities
that can be well suited for given situation in relation to the need for
technical competence.
Among other things the project manager should inspire confidence, drive, be a
decision maker, engage and own some form of basic knowledge in the field of
system development.
3D-byggnadsmodeller utifrån takkonstruktioner : Lagring, hantering och bearbetning
A growing number of cities and municipalities in Sweden begin to work with city models in 3D. For the most part the models are used for visualizations of ongoing planning processes, but also for the analysis of noise, shadow studies and environmental disaster simulations.Gothenburg continues to develop the use of 3D maps in municipal operations and is demanding a way to create building elements (walls), which generates in 3D buildings, from roof constructions that are mapped from the primary map. A method has been investigated in the present study. The results are then presented as a 3D model of buildings, along with a terrain map that will facilitate the localization of the area. The created 3D buildings are then compared with roof-data from the primary map to see how well they harmonize with each other.

Att reducera lagernivån : en studie vid SKF Mekan AB
Background: The increasing competition on the market demand both companies and supply chains to find optimal solutions. The edeavour to reduce inventory levels is a part of this. Earlier, inventory was seen upon as valuable assets, but today they tend to be more and more negative in the eyes of the companies. Inventory demands capital, handling, and space. Therefore inventory creates unnecessary costs.
Uppvärmningssystem - En analys av valmöjligheter för småhus
When constructing a new house many questions appear, from architecture to decisions regarding installations. Sweden is situated in a cold part of the planet and questions regarding which heating system to install face everyone who decides to build a new house. This thesis describes a construction solution of a villa in Kiruna. The extended essay analyzes which heating system is most suitable for the construction. The options are geothermal, district and pellet heating systems.
Harmony Korines verklighet : En studie om realism i filmerna Gummo, Julien Donkey-Boy och Trash Humpers
I denna uppsats studeras realismens framställning i filmskapandet, dels genom visuella tekniker men även genom handling- och ämnesmässiga val. Studien fokuserar på tre filmer som alla är regisserade och skrivna av filmskaparen Harmony Korine, dessa filmer är: Gummo (1997), Julien Donkey-Boy (1999) och Trash Humpers (2009).För att studera filmernas framställning av realism utifrån syftet med studien diskuteras och appliceras teorier angående ämnet från bland annat John Orr, Robert Stam och Geoff King. Eftersom syftet med studien är att studera realismen utifrån de specifika val som Korine har gjort i filmskapandet diskuteras även idén om en auteur. Både teorierna ifrån Orr och King är grundade i auteurteorin. King har även en utgångspunkt i den amerikanska independentfilmen som Harmony Korine är en aktiv filmskapare inom.I analysen diskuteras sedan Gummo, Julien Donkey-Boy och Trash Humpers separat och med hjälp av de framlagda teorierna om realism argumenterar analyserna olika sätt som filmerna framställer realism genom de visuella samt de handling- och ämnesmässiga valen..

Värmesystemsutveckling
In cooperate with Asko Cylinda we have developed a new heat system too short the process
time and reduce the energy consume in a dishwasher and still have it too be a class AAA.
The environment and quality is important for the company too still be the number one on
the market, If they want too keep that position the product developed of new innovations will
be very important. The systems we have developed are more effective and reduce energy up
too 25 %. The process time is reduced too less than two hours, from the today two and
half-hour. The solutions are too heat up the rinse water and the dishwater at the same time,
with a new heating system and it make are solutions unique and effective. Its good for the
dish and the environment.
Hur ser medborgarna på den lokala planeringen? : - en granskning av detaljplaner i Växjö kommun
Vår yrkesmässiga erfarenhet som hälsopedagoger har fått oss intresserade av att undersöka den pedagogiska aspekten av det lärande som rehabiliteringsdeltagare gör som hälsobefrämjande aktivitet i samband med en arbetslivsinriktad rygg- och nackrehabilitering vid Svenska Rygginstitutet AB. Syftet med studien är att undersöka om och i så fall på vilket sätt en arbetslivsinriktad rygg- och nackrehabilitering bidrar till deltagarens lärande, insikter och befrämjande av hälsa. Fyra deltagare som genomgått en sådan rehabilitering intervjuades. Intervjuerna spelades in och transkriberades för vidare analys utifrån kvalitativ narrativ metod. Undersökningens resultat visar att upplägg där aktivt lärande betonas och informationsförmedling samt reflektion varvas med att praktiskt få prova på och erfara, gör förvärvande av såväl nya insikter och kunskaper som ökad förståelse möjligt och tillgängligt.
Prestation vid sönderdelning av GROT med olika typer av maskiner
There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.
Motivation : Vilka motivationsfaktorer driver nyexaminerade poliser
Bakgrund: Motivation är viktigt för att driva en till handling vilket alla har erfarenheter av. Oavsett vad det är för handling så ligger där alltid någon form av drivkraft bakom denna. Vi fann motivationsfaktorer inom den offentliga sektorn som mycket intressant och då främst polisyrket med deras unika arbetsuppgifter. Detta gjorde att vi ville undersöka vad poliser motiveras av. Problemformulering: Vilka motivationsfaktorer driver nyexaminerade poliser? Syfte: Syftet med denna studie är att söka en förståelse vad det är som motiverar nyexaminerade poliser. Metod: Studien som gjorts är genomförd med en kvalitativ forskningsdesign.
