The purpose of this study is to compare the energy related and environmental consequences of implementing optical sorting as a means of waste collection with those of reducing food waste. In addition to studying the possibility of implementing optical sorting in downtown Stockholm, the yielded amounts of energy from waste collection and reduced wastage will be calculated. This is done by way of literature reviews and interviews. The amount of energy that can be generated through optical sorting and biogas production via anaerobic digestion in downtown Stockholm is 29-44 TJ/year, compared to 118 TJ/year saved by completely eliminating food waste. The generated biogas can replace fossil fuels, but the required food waste contributes to increased greenhouse gas emissions as well as reduced bio diversity and eutrophication during the wasted food?s lifecycle.

This thesis looks at two sides of the same coin: how to support the production and future development at a specialist medical technology department at Danderyd Hospital. The two sides are; a pilot study of a product management system (PDM) and an interview based study on the characteristics of the silent knowledge of the technicians. The department (National respiratory centre, NRC) is facing retirement of several key employees.The technical study shows that the success of an implementation is largely dependent on the users? prior knowledge and use of a 3D Computer aided design system (CAD).The system itself is shown to fulfill the Lifecycle requirement of tracking the products (mostly tracheostomy tubes) but without a CAD centered workflow, some substantial education and preferably some new recruits, an implementation of the PDM system will fail. The author recommends development of the current ?low-tech? system of MS Excel and Access rather than redistribute the dependency from technician towards a complex, commercial software and its vendor.The analysis of the technicians? silent knowledge with the newly developed method, epithet for silent knowledge (ETK), shows that the longer employment time:the more differentiated technicians become in describing their work,practical knowledge are regarded higher andthe social and collective problem solving factors of the work becomes more important.Typically, it is shown that a new employee should preferably enjoy problem solving, being pragmatic and social as well as having some prior education or work experience in a CAD and/or a PDM system..

The aim of this thesis is to examine how personnel working with asylum cases at the Swedish Migration Board handle their role as administrators of asylum. For the study 7 asylum administrators were interviewed and the analysis was made with influence from the method critical discourse analysis. To understand the themes in the analysis I have used Michael Lipskys theory about street-level bureaucrats. Main results from the analysis of the interviews were that the street-level bureaucrats had certain strategies for managing the difficult aspects of the job. The interviews also showed that the participating informants had difficulties with different identity positions..

The Uppsala based company Q-linea develops procedures, instruments and systems for protein and nucleic acid analysis. The components in such an instrument are controlled by microcontrollers. Microcontrollers are computers in one singular chip that can be used in a wide range of applications such as cars, toys or in this case an analysis instrument. When developing a new instrument for biochemical analysis, Q-linea needed new software for controlling and communicating between the components in the instrument. The process of developing this software is the subject of this thesis.The project included research of microcontrollers and the components in the instrument.

Rapporten som följer är en analys av en metod som genererar regler från neurala nätverk. Metoden heter VI-Analysis (Validity Interval Analysis) och är framtagen av Sebastian B. Thrun [Thrun]. VI-Analysis arbetar på det sättet att det neurala nätverket ses som en svart låda där endast de inputvärden och outputvärden som finns i nätverket används som underlag när regler ska genereras. Dessa inputvärden och outputvärden kommer sedan att få tillåtna intervall av VI-Analysis.

Sapa Heat Transfer is a company that produces aluminum heat-exchanger strips for the automotive industry. Sapa Heat Transfer wish to chart their emissions of carbon dioxide in order to meet future demands on carbon dioxide reporting. They also would like to examine the meaning of the term ?green electricity? which is marketed as carbon dioxide free, and the sort of electricity that they purchase. This report includes both direct (liquefied petroleum gas and diesel) and indirect (water, process-water, long distance heating, waste) emissions from their company.

The parasite Neospora caninum is an intracellular protozoa discovered in the late 1980s. N. caninum has an indirect lifecycle which means it needs a definitive host and an intermediate host. The confirmed definitive host for N. caninum is dog and the intermediate hosts are among others dog and cattle.

The regulations for energy consumption are consistently getting more and morestrict. This leads to a higher customer demand for energy analysis early in the buildingdesign process. Many building planners and architects use powerful modeling softwareto visualize their projects. These digital models contain sufficient information aboutthe building?s physical characteristics for reliable energy analysis.

This study aims to investigate how small scale manufacturing companies reason around an implementation of a PLM-system, as well as the suitability of these systems compared to larger companies. The study is built on a qualitative method. Initially, secondary data was gathered through books, articles and reports. Primary data was gathered through four interviews. Two interviews were performed with PLM resellers, one interview was performed with a PLM developer, and one interview was performed with a small scale manufacturing company that opted to not implement a PLM-system.The results imply that overall differences between larger and smaller companies exist in regard to the need of PLM systems.

The essay circulates around the technological analysis of flint material from four localities around the Baltic Sea basin. The analysis was created to investigate the question of where the first Gotlandic settlers originated from and to give clues about the colonization process. The investigated material was collected during the fall of 2011 and a correspondence analysis is used to analyze the collected material. The purpose of using a correspondence analysis is to test the method as a tool for investigating Mesolithic flint technologies. The essay also discusses marine hunter-gatherers, their economy and how their archeological remains differ from terrestrial hunter-gatherers..

With the help of image analysis and scent theory, we have made an analysis that explains how the perfume smells in advertising. There are many different factors that play a role in our perception of smell by image. We have found that using the connotations we can get a sense of the scent. What helps us along the way, the colors, the women and the environment. From this one different conclusions are mad and we create a scent sensation..

The purpose of this essay is to examine cost-benefit-analysis as a method of evaluation of labour market policy. To illustrate the possibilities and difficulties of the method chapter four contains a partial cost-benefit-analysis of the results of a labour market project in Kävlinge. The questions this essay strives to answer are the following: What possibilities and difficulties do cost-benefit-analyses entail? How would one conduct a cost-benefit-analysis of the project in Kävlinge?The method used in this essay is mainly a literature study of cost-benefit-analysis of labour market programs. The labour market project Brännpunkt is used as an example in a partial cost-benefit-analysis.The applied cost-benefit-analysis of the Brännpunkt project in Kävlinge shows that it is possible to calculate the profit for the society as a whole, given that the necessary information is obtainable.
