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.

Kommunikationshjälpmedel Sound and Display Communicator

During the last year in the Innovation Engineering Program, at Halmstad University, a degree project was performed that was carried out during Fall semester in 2006 and Spring semester 2007. The project was performed by two students in corporation with LIC Audio AB, a company in Stockholm. The degree project was meant to result in a communication aid for people with a cognitive handicap. The project focused on people suffering from dementia because of the expressed need within this group. This aid should first and foremost help in a conversation between a person with dementia and another person, like a relative or nursing home staff.

Slagfältarkeologi : Metod och möjlighet att lokalisera och undersöka förhistoriska bataljplatser.

This essay is a study regarding the existence of Bronze Ages and Iron Ages battlefields in Scandinavia and the possibility to trace and find them by using the Battlefield Archaeological Method.Based on a theoretical background and results from historical battlefield research and excavation experiences, the discussion deals with some of the problems and possibilities of applying the Battlefield Archaeological Method on older places. The existence of these battlegrounds is also an unknown factor, and a major part of this study is trying to find evidence of their existence. For that purpose I am using as an example a deeper analysis of an Iron Age battlefield archaeological excavation in Germany in order to compare and draw parallels with the Scandinavian society of that time. I am also using the evolution of weaponry, in particular the sword, to show parallels between the Mediterranean and the Scandinavian societies in the matter of warfare and tactics..

Windows, RedHat och IPv6 - ett test!

With the huge amount of computers connected to the Internet the IP-addresses are starting to run out. The Internet Engineering Task Force, IETF, have decided that it is about time to exchange the old 32 bits Internet protocol, Ipv4, to a more modern 128 bits protocol called Ipv6. This thesis explores the possibility to install Ipv6 in different operating systems. By testing various operating systems and by set up criteria compare them to each other we give the reader a picture of how the installation is done. We also show which operating systems to prefer if you want to use IPv6.

Elev i behov av särskilt stöd : Vad betyder det?

This is a qualitative study of how 4 school teachers and 3 special educational teachers define the term ?pupil in need of special education?. They have each one been interviewed about this term, by the means of a semi-structured interview. Afterwards the collected information has been analyzed and seven major themes have been arranged out of them. From these themes it is possible to see that the term is hard to define, since the participants all believe that it should be decided by each individual case, if the pupil is in need of special education or not, and that the education in itself has to be relevant to the need, which means one cannot decide what special educational needs are, without a student who is in need of them.

Diagnosens betydelse : En grupp pedagogers uppfattningar av diagnosens betydelse

The thoughts of a common school for all children have been around since the 1800?s but was something that was introduced in Sweden first in 1962. When the curriculum for primary school came in 1980 there was a new concept, a school for all. With a school for all it was aimed that all children should have the right to participation and a common education no matter what needs they could have.During my education I have come across the concept a school for all and that is something that interested me. Today?s curricula and school laws aim to ensure that all children have the right to equal education and inclusion whatever needs you have.The purpose of this study is to find out some pedagogues? thoughts and work around the concept a school for all.

Laserskärning i Sverige : ? tekniken, marknaden och hur de utvecklas

Laser for material processing possesses a number of advantages which mean that it has been and will be an important component for a wide range of industries' future development. Cutting materials processing is the dominant use of laser technology and has revolutionized the manufacturing industry. The aim of this thesis is to describe the principles of metal cutting by laser, how laser cutting is applied in practice and to identify how Swedish companies are using laser cutting. For the theoretical and technical description of laser cutting literature studies are the primary source of information. The empirical basis for the mapping of the Swedish industry for laser cutting is grounded on a survey; this includes Swedish companies that use laser cutting in their production.

En studie om studenters användning av vänlistor på Facebook

Friend lists allow Facebook users to group their friends and may be used to share certain information only with those in a specific list. This function has been around for several years, but has never gained any particular popularity among users, most of whom probably did not know it even existed a couple of years ago. In the fall of 2011, however, the function was updated and made more visible on the site.There are several possible uses of friend lists, such as privacy control, filtering of the news feed, self-presentation and targeted information sharing. This paper aims to investigate the extent to which friend lists are used by students today, as well as why students actually use their lists, i.e. for what purposes.Judging from the results of this study in comparison with earlier research, there seems to have been a somewhat recent increase in the awareness of the fact that friend lists actually do exist, but still most users tend not to utilize them.

Hur kan vi utveckla vårt personliga uttryckssätt med ljud?

The goal has been to create an illustrated story in a form of a book. The story is about the feeling of being alienated from other people and invites the reader to make their own interpretations. The main target audience has been the ones who is interested in illustration and storytelling, no matter of age.Colors has been inspired from animated movies and the natur. Various textures such as wood, fabric and metal for example has been scanned to create a rough feeling.

Produktion av Pyrolysolja från kvistrejekt

Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting.  Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.
