Konstruktion av fackla för biogas

Värmekollektor in Sunne is a company whose main occupation is to collect the gas produced inlandfills. The gas contains about 50 % of Methane which is a greenhouse gas 20 times worse than CO2and should therefore not be allowed to leak into the atmosphere. The Methane is in as large amount aspossible used in different plants for example heating of households. But there are occasions when aflare is needed to burn the excess gas at standstills or testing of new landfills. The Flare only burns themethane to reduce the hazarder?s effect of the environment, it does not take advantage of the energy inthe gasThe goal of this master thesis was for me to create a foundation for an in-house production offlares for Värmekollektor.

Jämförelser av olika former av QRA och andra metoder för riskanalys av processindustrier

When performing a QRA you have to consider a number of accident scenarios. How many scenarios you choose often determines the time and resources needed to perform the QRA. The report investigates the possibility that a QRA can be performed using only a few representative scenarios. Further it presents a discussion on how these scenarios should be constructed..

Optical and Structural Properties of CuxS Quantum Dots Concerning H2O/Ethanol Solvent Ratio

Nanotechnology, one of the most interesting sciences today will no doubt have an enourmous impact on tomorrow's society and industry. One of the most interesting nanomaterial that has been discovered is the semiconductor quantum dot (QD). This material shows interesting novel properties such as a size-dependent band gap, which is an effect caused by the quantum confinement effect in all three dimensions. Due to this phenomenon the absorption spectrum can be tuned to the desired value by adjusting the size of the QD.This thesis aims to investigate how the solvent ratio of H2O/Ethanol affects the optical and structural properties of copper sulfide QDs manufactured in a chemical synthesis way using modern microwave heating. The process of manufacturing QDs using chemical synthesis often involve a capping-agent to prevent the QDs from agglomerate into bigger structures.

Utfackningsväggar ur lufttäthets- och fuktsäkerhetsperspektiv : En jämförelse mellan platsbyggda och prefabriceradeutfackningsväggar

The swedish national board of housing, Building and Planning,recommends that all stakeholders in the construction industryperform a moisture control design to make sure that the buildingachieves good moisture resistance. Since June 1, 2006 there are nospecific requirements or quantitative values for air leakage.Although the swedish national board of housing does presentrequirement that the building envelope must be sealed so that theclient?s requirements for specific energy consumption and installedelectric power for heating purposes are met. Despite this, studiesfrom SP shows that few buildings meet the client?s requirements inspecific energy, which increases the risk of occurrence ofcondensation-related moisture damage.This study aims to evaluate curtain walls connections from airsecurity and moisture safety.

Ett kreativt samarbete

Vi ämnar, med denna uppsats, att utforska det kreativa området efter ett fenomen vi valt att kalla för Det kreativa samarbetet. Uppsatsen undersöker om huruvida en arsenal av kreatörer inom olika kompetensområden kan vägas mot den ensamma kreatörens arbetssätt. Sammanfattningsvis vill vi undersöka kombinationen av de två begreppen kreativitet och samarbete och dessas inverkan på en arbetsprocess inom kreativt skapande..

Termisk Vattenpump

 This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.

Stabilisering av process

Calesco Foil AB is a manufacturer of thin flexible circuits for heating or electric conduction.The plant is located in Kolbäck, Sweden.One of the company?s products, the conducting polymer pasta is in present situationunpredictable. Unpredictable in the way that the same type of heater shows differentresistance, depending on which time they have been produced. The desired repetitivelyprocess is almost non-existing.The aim of this master thesis is to primary identify those parameters that effects theresistance, observe and if possible to perform tests on them. The results from this analysisstand as base for recommendations to achieve a repetitive and standardized printing process.The results and the observations from the tests indicate that a repetitive process is possible toachieve.

Ljuddesign för bildkonst

Detta arbete beskriver hur man ljudlägger konstfilm, hur man plockar upp ljud vid inspelningsplatsen och hur man ställer ut en flerkanalig ljudläggning av en konstfilm. Detta är de tre huvuddelarna i detta kandidatarbete, och dessa kommer att förklaras med hjälp av mitt eget tillvägagångssätt, tillsammans med problem jag stött på och hur jag löst dem. Reflektionen redogör även för betydelsen av kommunikation mellan konstnär och tekniker och hur man som ljudansvarig kan använda sin maximala kreativitet och kunskap, samtidigt som upphovsmannen ska få som hon/han vill..

Svensk vindkraft

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Simple Contact Access

Målet med projektet är att utveckla ett system där det skall gå att komma åt information från en intern databas på ett enkelt sätt med en mobil enhet. Eftersom varje enskild databas är unik så skall det gå att justera systemet enkelt genom ett administrationsgränssnitt så att det passar till varje databas. Informationen är oftast känslig och skall inte åtkommas av obehöriga användare, så den mobila enheten behöver autentiseras för att skydda informationen. Systemet kommer alltså bestå av ett par applikationer:1. Webbtjänst som skall kommunicera med databasen och skicka information till webb- och den tjocka klienten.2. Webbaserad klient, skall kunna visa data från databasen.3. Tjock klient, skall kunna visa samt uppdatera data från databasen.4. Administrationsgränssnitt som skall kunna konfigurera webbtjänsten. För autentisering av användaren används telefon ID:et och sköts automatiskt av den tjocka klienten.

Utfodring av föl före och efter avvänjning :

Swedish horse breeders have generally very few mares producing a few foals a year and the breeders have relatively few traditions, little knowledge and experience to breed foals successfully. It is therefore important to provide adequate information about new findings in horse nutrition. However, there is not much research about feeding the suckling foal to ensure a sound growth. Current feeding recommendations in the literature seems to be different. This gives a confusing message and the information is difficult to apply. This paper reviews some publications in the area of feeding the suckling and weaning foal. Most authors stress that it?s important to start feeding the foal early in life.

Studentrekrytering : det bortglömda kapitlet inom eventkommunikation

Student recruitment is a subject that seems to be forgotten in the theory of event communication. Yet the area has some specific reoccurring features. Our purpose was to examine these specific features and how to work with these in the best way, and also see how to get the most out of the event communication to the young at event and fairs. Special features we have looked at are the student ambassadors ands their impact, the meaning of a give-away and also if there are any essential factors to get in contact with the young at fairs and events, and if new technology had an important role to play in the area.Our research has been inductive, and therefore, we have created our own theory and reflected it to the larger topic of event communication and its theories. Our research method has been triangular, both quantitative and qualitative; interviews with those who work with student recruitment, and surveys to young people in upper secondary school.Our study showed the importance of student ambassadors and their specific task to be nice, friendly and outgoing.

Aktörer och artefakter : Ett samtida perspektiv på bibliotek och automatisering

This bachelor thesis examines the activities and values associated with automation and technical development at four Swedish research libraries. It does so by applying textual analysis to annual reports and job advertisements from the respective libraries. The study also questions whether some assumptions of automation have changed or remain over time, and includes a short historical discussion in relation to the contemporary analysis. As an added perspective it introduces the methods and philosophies of French sociologist Bruno Latour. The author reflects on the merits of Latour in research of library automation.

Mätning av kranskärlet LAD:s slingrighet : en pilotstudie

The background to this report is the author?s ambition to understand individuals? work situation, how it?s formed in interaction between the individual and factors in the work-setting. Such an ambition is well in line with the concept of Human-Technology-Organization (HTO), a cross-scientific approach that puts a system-oriented perspective on how human, technolog-ical and organizational factors interact within work systems.The aim of this report was to explore managers? work-situation and generate an understanding of it from an HTO-perspective by using an organizational model as a framework for an interview guide and to analyze the work situation from an HTO-perspective following the ques-tions at issue:1. How does the managers experience their work situation?2.
