Implementering av Constant Fraction Detection vid avståndsmätning
This thesis is performed at Saab Bofors Dynamics in Karlskoga and investigates a technique for ranging with laser pulses. The investigated technique is called Constant Fraction Detection (CFD). Described briefly, the received laser pulse is split into two equal parts, where one part is delayed half the pulse width and inverted. This signal is added to the original pulse. The resulting curve has the shape of a laying S and the detection of the zero level is used to stop the time measurement.
FE-modellering av hjullast på sandwichpanel
This bachelor thesis in mechanical engineering was performed during the spring2015 in collaboration with Composite Consulting Group in Laholm. TheComposites Consulting Group works mainly with design and details of differentcomposite projects, their main area is FE-calculations, 3D-modelling andmechanical tests with composite materials.The aim of this bachelor thesis was to simplify the calculation process of solidmechanics for sandwich panels by simulation with computer software. The goalwas to decrease the time for the design and calculation process of the constructionand the cost of the practical tests. Our task was to build a static three dimensionalmodel with the computer software Abaqus, where the result should correspondwith the practical pressure tests in laboratory.The project started with collection of material data from Composites ConsultingGroup and by learning the software Abaqus, simultaneously a specification wasdeveloped in corporation with the company. Later on, a static wheel pressuremodel in the software Abaqus was produced which simulated the behavior of thesandwich panel during static wheel-pressure by a pallet truck.
Bergkyla och bergvärmeutredning för industrilokalen Rödbergsmyran 5 i Umeå, Västerbotten.
Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.
Minimizing acts of violence through telephone-linked care: an
automated telephone system for outpatients in forensic
psychiatric care
Achievements within the fields of computer- and telecommunication technology have led to a revolution when it comes to managing information. These achievements have made it possible to offer new services in healthcare, especially in telemedicine. New technology has become a complement to traditional care, thus partly compensating for insufficient time and resources. Telephone Linked Care (TLC) is a telecommunication technology that enables automated dialog counselling and monitoring of patients in their homes. During the last two decades numerous randomized controlled studies with TLC have demonstrated improvement among outpatients with chronic and health behaviour disorders.

TILLFÄLLIGA EFFEKTTOPPAR I FJÄRRVÄRMEN : Kan man med hjälp av lagrad värme undvika att de uppstår i betonghus?
Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.
Glava glasbruk : En undersökning av föroreningar i mark- och vatten samt ansvaret för dessa enligt miljöbalken
The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.
Drank som proteinkälla till regnbågslax (Onchorhynchus mykiss) :
The objective of the present study was to evaluate distillers? dried grains with solubles (DDGS) as a protein source to rainbow trout (Oncorhynchus mykiss), by studying digestibility and growth measurements. One control diet, totally lacking DDGS, and three test diets were made containing 10 % (low), 31% (medium) and 51 % (high) DDGS respectively on dry matter (DM) basis. The control diet and the test diets were made to be as nutritionally equal as possible. Wheat bran was used to balance the fiber content of the diets.
Användbarhetsutvärdering av en grafiskt visualiserad patientjournal
First-year students at Linköping University have developed a prototype that graphically visualizes a medical record in a new way. The customer of that project was the Department of Biomedical Engineering at Linköping University. They now want a usability evaluation to be performed of the prototype. The prototype is to be used by employees in the public health care and is supposed to be used on a small portable unit with a multi-touch interface. For this reason the prototype will be used as a complement to existing systems when the users work near the patients.
Arkitekturer i operativsystem: en fallstudie i monolitisk och micro kernel
Den tekniska utvecklingen driver fram allt mer avancerade
datorsystem. Samtidigt ställs allt större krav på stabilitet
och flexibilitet i de operativsystem som ska användas på
dessa system. De senaste årtiondena har micro kernel
arkitekturen varit föremål för intensiv forskning och det
finns idag ett flertal operativsystem på marknaden som
använder denna arkitektur.
Traditionella monolitiska operativsystem är relativt
resurskrävande system som ofta anklagats för att sakna
struktur. Micro kernel baserade system är en lösning på
detta problem där man bantat ner kernel till så lite som ett
tiotal kilobyte och flyttar ut tjänster som normalt ligger i
kernel till user space.
Solaris och Linux bygger på en utveckling av monolitisk
kernel där man byggt operativsystemet i ett antal
sinsemellan beroende lager vilket bidrar till ökad struktur i systemet.
Flexibilitet uppnås i dessa system genom att man
lägger till funktionalitet för att under exekvering länka in
ny kod i kernel.
Windows NT och Mac OS X är baserade på micro kernel
arkitektur.

Aurora - Technology made to make things easier
Det började faktiskt redan hösten 2004, när jag satt och arbetade med ett av de
otaliga projekt man gör under sin skolgång. Projektet gick ut på att skapa en
hemsida med en digital katalog, och voilá, där föddes idén.
Sedan fortsatte jag att fundera, vända och vrida på idén, ett system för att
skapa digitala kataloger och mindre presentationer som vemsomhelst skulle kunna
använda. Just detta att inte exkludera de som inte kan ?Flash? från de som
skall kunna redigera systemet har varit en av mina stora grundpelare, ett slags
digital demokratitanke.
För att skapa systemet har jag använt ?Macromedia Flash MX? och dess inbyggda
programmeringsspråk ?ActionScript?. Programmeringsspråket är inte ursprungligen
tänkt att användas för att göra system, men jag tycker personligen att jag
lyckats bevisa att det fungerar även för det ändamålet.
Planering, förutsättningar ocheffekter av implementering avsolceller i stadsutvecklingsprojekt.
Today, buildings utilize 40 % of the total energy consumption. New energyrestrictions and directives have entered the construction industry. Photovoltaic is asustainable, clean and quiet solution that integrates well in the urban environment buthave not yet reached a breakthrough on the Swedish market. The conditions for solarenergy production are often set in the early planning stages where they rarely arebeing prioritized.This master of engineering project focuses on identifying problems regardingimplementation of photovoltaic in city development projects and giving suggestions topossible improvements in the planning- and construction process. It also givesrecommendations on how the conditions for energy production can be optimized inthe early zoning stage.By conducting simulations with PVsystV5.21, on three ongoing city developmentprojects in Umeå, Malmö and Stockholm and by carry out and analyzing interviewswith city planners, constructors and architects, some conclusions have been made.Several improvements, both politically, with changes in the subsidization systemand/or instatement of a new law with feed-in tariffs, and within the solar- andconstruction industry itself, with better communication between different parts of theprocess as well as better use of experience, can be made.
Web Services - Aspekter på nya affärsmöjligheter
E-business innebär att företag använder
Internetteknologier eller nätverksteknologier för att
skapa större affärsnytta i deras affärsprocesser. För att
kunna genomföra automatiserade affärsprocesser krävs
att de olika system som används är interoperabla, d v s
kan kommunicera och fungera ihop på ett effektivt sätt.
Målet med Web Services är att skapa hög
interoperabilitet, vilket gör denna teknik lämplig för e-business.
Företag kan specialicera sig på att skapa
specifika Web Services. Dessa Web Services kan sedan
vara byggstenar åt andra företags tjänster. Det krävs då
att Web Services kan integreras på ett bra sätt så att de
verkligen bildar en affärsprocess. Därför är även frågor
kring hur integration mellan Web Services ska gå till,
viktigt ur ett e-bussiness perspektiv.
Det vi kommit fram till är att det går att minimera
integrationsproblemen genom att anvä nda de mest
standardiserade protokollen och följa vissa riktlinjer vid
skapandet av Web Services.
