Design av en ejektorspädare samt ett system för partikelmassmätning av dieselavgaser

This master thesis was a subtask of a project called EMIR-1. The goal with the thesis was tobuild a system for particulate mass measurements in one of the engine test cells at KTH. Theparticulate mass measurements are planned to be measured with a TEOM.The exhaust gases must first be diluted with air before the sample is sent to the TEOM.Therefore an ejector diluter for this matter also was designed and evaluated in the thesis.Emissions measurements have been done both with and without dilution to determine thedilution ratio. Tests have been done for different speeds and loads.Problems with stability of the dilution ratio have been an issue throughout the process andpressure pulsations in the exhaust pipe are believed to be the cause. More tests have to be done tomake sure that this is the problem.One idea is to make the inner diameter of the diluter nozzle smaller and see if it changes thedilution ratio stability.

Social upphandling : Ett uttryck för public-private partnership?

The purpose of this thesis is to examine how social procurement can be a further development of public-private partnership. This is done with interviews and a case study of the social procurement Mitt Gröna Kvarter and its labor effort Boendebyggarna. The theoretical framework used in the thesis consists of public-private partnership and corporate social responsibility. It tries to answer the following questions:What does this social procurement mean by the concept of public-private partnership?What does this social procurement mean for the participants involved?How can social procurement be seen as a further development of public-private partnership?The thesis uses the theory development around the concepts of public-private partnership and corporate social responsibility and shows that social procurement does indeed have similarities to public-private partnership and could very well be a further development of it..

En genomtänkt introduktion : En studie om vilka faktorer och metoder som påverkar introduktionen av nyanställda på företag 

The master thesis has been constructed together with Scania, who had a wish to develop their training for newly employed design engineers. The purpose of this thesis is to examine how a company's introduction process can be shaped, as the introduction is the key to success for the individual as well as the organization. With a focus on how the productivity among newly employees can increase and how the introduction becomes meaningful to the individuals and the organization, the objective of this work is to develop concepts applicable for an introduction.The work was conducted using qualitative interviews with several different individuals at Scania and other companies. Along with the interviews a survey was constructed and sent out to newly employed design engineers at Scania to get a view of their opinions on the present training. During the first period of a job there are several factors that affect the employee based on the result from the interviews, previous research and theories.

Aristoteles och cyberspace : Kunskaper, färdigheter och insikter i hypertextens föränderliga värld

The purpose of this thesis is to deepen the understanding of our contemporary description of digital literacy using the perspective on knowledge from the Nicomachean Ethics by Aristotle. I have chosen to deal with the problem using a hermeneutic approach. The method of inquiry is based on close reading of the selected literature. The selection itself has been made after a strategic selection regarding perspective on knowledge and digital literacy. It appears in the thesis that there are substantial differences but also similarities between our contemporary description of digital literacy from Recommendation of the European Parliament and of the Council of 18 December 2006 on key competences for lifelong learning and the perspective on knowledge from the Nicomachean Ethics by Aristotle.Still, the result has been possible to use for the purpose of the thesis since the problem has an answer and a deepened impression of the understandings of digital literacy..

Betydelsen av öppenhet, deltagande och ansvar i utformningen av megaprojekt En analys av policyprocessen kring ESS-projektet mellan 1990-2008

This thesis consists of three parts: one normative, one empirical and one constructive, with the intention to explore the enforcement of accountability in megaprojects.The thesis aims to evaluate the level of accountability in the policy process of the European Spallation Source, ESS between 1990 and 2008. In order to make a comparison possible, a norm is created concerning how a policy process should be designed, with primary focus on openness and participation, to make enforcement of accountability possible. The policy process of the ESS is compared with this norm with the purpose of discovering whether the process contains elements that assure enforcement of accountability. After the comparison is done, it is possible to formulate constructive proposals about how the enforcement of accountability can be improved.The thesis also explores how networks, consisting of actors with particular resources, surrounding the ESS-project affects the form of the policy process, e.g. in shaping the social construction of the aim and purpose of the project.

Kvalitetsledningssystem enligt ISO 9001 : Produktionsprocessen

This report is the result of a thesis work done at the Department of Engineering Sciences, Uppsala University, and includes 15 ECTS points. The work has been performed at Företag A, a company specializing in electronics whose major product has become a sophisticated tool used by authorities across northern Europe. Företag A has initiated a quality management system according to the criteria set by ISO 9001. Following demands from customers, Company A has now decided to also start working towards a certification according to SS-EN ISO 9001:2008, this work is the foundation for the thesis work. The thesis work has been limited to the production process and the aim has been to enable this process to be certified according to ISO 9001:2008. The work has been performed by analyzing the existing quality management system and the requirements for each process included, whereby the gap between the current and the target state has been mapped. Suggestions have then been made on how this gap can be filled, some of these suggestions have also been carried out during the thesis work. The conclusions drawn are that quality management does not have to be complicated, but quickly becomes so when the complexity of the processes increases.

Valuing Green: A Qualitative Study on the Priorities of Values, Personal Norms and Identity for Green Consumer Products

The purpose of this thesis is to contribute to a further understanding of the complexity in green consumer behaviour by examining how and why individuals priorities values, personal norms and identity in green consumer behaviour. The thesis employs a qualitative approach with an abductive strategy. The empirical data was produced through in-depth interviews with green consumers. Based upon the empirical findings and theoretical concepts, a conceptual model was introduced to illustrate how consumers prioritise between several values when assessing green products. The prioritisation is dependent on internalised values as well as the product function and the need that the consumer seeks fulfilled.

Kommunikationsgränssnitt för hårdvaruinventering av IS-baserade system : Communication interface for hardware inventory of Integrated Site

The purpose of this thesis was to create a communication interface which insures that all the right hardware is in its right place in the IS-node before Ericsson AB delivers it to their customers. One of the first parts of this work was to make sure it is possible to create such an interface for IS. This thesis then explains how to construct an interface that retrieves information from the IS-node into a C#-application. One important part of this project was to collect information and transform it to an XML output with the purpose of then being used in other applications in the future. The application created within the scope of the thesis exports the information retrieved from the IS-node in an XML-file or a text-file.

Spam : den nya tidens onlinegissel

This thesis takes on a broader perspective of the modern age phenomenon we call spam. One of the aims of this thesis is to present and to compare the variety of methods used in the day-to-day fight against spam, as far they have evolved today, but also to present and discuss some alternative methods for suggested future use. The properties of a common e-mail spam are analyzed to show how the components that make up the structure in an e-mail can be used to classify spam. Furthermore I explain the naïve Bayesian classification methods, the signature-based method, the commonly used rule-based method and the challenge and response method and discuss these. The widespread use of blacklists is also explained and a close new variant to blacklisting, Turntide is presented and discussed.
