Konstruktion av testrigg för moderna ångexpandrar
This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.
Mikrokrediter, kvinnor och empowerment - Exemplet Grameen Bank
Since Muhammad Yunus, founder of the microloansorganization Grameen Bank, was awardedthe Nobel Peace Prize in 2006, the microloansorganization has received much attention. Thewoman has come to play a central role in the microloansorganizations. Her access to capital isis considered to improve her socioeconomic status. The overall aim of the paper is to examinehow access to microcredit considered leading to empowerment of women. To get an idea ofwhat a microloansorganization is the Grameen Bank is used as an example.
Automatisk tesauruskonstruktion med latent semantisk indexering
The aim of this thesis is to examine how thesauri constructed with latent semantic indexing LSI are performing when used for query expansion. There is a well-known problem with synonymy in information retrieval and one solution to this problem is to use a thesaurus. In this thesis thesauri are created automatically to find statistically related words and not only synonyms. LSI is a method that uses singular value decomposition SVD to reduce dimensions in a matrix and find latent relationships between words. We constructed nine thesauri and used them for query expansion in a Swedish database, GP_HDINF.
Porr och rasistisk propaganda på svenska folkbibliotek : skall folkbiblioteken tillåta ett fritt internetanvändande eller skall man kontrollera sina internetterminaler?
This paper deals with the use of Internet at Swedish public libraries. The author asks whether public libraries should or should not limit access to information available on the Internet. Starting from the American discussion, concerning Internet at public libraries, the author shows the Swedish attitudes. The paper demonstrates that many Swedish public libraries have adopted rules forbidding retrieval of certain kinds of information, such as hard-core pornography and racist propaganda. The persons in charge of such actions claim that public libraries should provide high-quality educational literature and should not spread mass-produced, provocative information.
Francisella tularensis subspecies holarctica : the curious case of a water- and mosquito associated bacterium in Sweden
Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern
hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of
mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two
prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in
close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.
Ledares rörelsemönster : ? en kvantitativ undersökning
New forms of Information and Communication Technologies (ICTs) have become more influential in development contexts. The concept of ?The Digital Divide? points at a large division between rich and poor countries regarding access to ICTs. Critics say that the debate concerning this topic for far too long has focused mainly on the technology itself rather than social factors which impact social inclusion and development. Scholars agree that ICTs holds a tremendous potential, but how is this implemented in development contexts and how can it be used with more sensitivity towards local preconditions and social aspects?This paper aims to examine how ICTs are being used in the context of development within an India based organisation for women called SEWA (Self Employed Women?s Association).
Processchemaläggare för mångkärniga processorer ? Fördelning av minnesbelastning i NUMA-system
For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.
WTO - spelarena för utvecklingsländer? En studie om avgörande faktorer för utvecklingsländers förmåga att implementera sina regimpreferenser
This Bachelor Thesis is entitled "WTO-spelarena för utvecklingsländer? En studie om avgörande faktorer för utvecklingsländers förmåga att implementera sina regimpreferenser". Through our empirical results in conjunction with realist theories, this Bachelor thesis attempts to answer the questions: (1) How does the decline in American power, the nature of existing institutional structure and Third World unity, influence the ability of developing countries to secure its preferred regimes? (2) What function do informal meetings in the WTO have? (3) How does access to informal meetings influence the ability of developing countries to secure its preferred regimes? The paper makes use of case studies from the Ministerial meetings in the Doha development round.The conclusion is that access to these meetings is an important variable to explain the extent to which the Third World can be able to secure its preferred regimes. The degree to which developing countries can secure their preferred regimes is therefore a function of four variables: the nature of existing institutional structures; Third World unity, the attitude and power of the United States and foremost access to informal meetings..

Willingness to pay for improved maize seeds among smallholder farmers : a study of the input factor market in Kenya
Kenya is considered to be a developing country. This means that basic needs such as nutrition are not met for an extended period of time (www, Sida 1, 2012). Approximately half of the population is living under the poverty line (www, CIA 1, 2012). Agriculture is the largest sector in the country, employing 75% of the population. These are thereby directly dependent on the sufficiency of outputs received.
Hemsideprojekt för Kulas Ponnystuteri
Syftet med mitt examensarbete var att utveckla en hemsida till Kulas Ponnystuteri. Den skulle innehålla vissa informationstexter, nyheter, gästbok m.m. samt administrationsfunktioner.Hemsidan skulle vara lätt att använda och hitta önskad information på. Den vänder sig till mer eller mindre hästkunniga människor i alla åldrar, och skulle därför göras mycket besöksvänlig.En hemsida konstruerades utifrån de önskemål och krav som kunden hade. För själva kodningen användes HTML och ASP med Java Script och arbetet skedde i både Frontpage och Dreamweaver.

Utveckling av kyl- och smörjsystem för ekobilen Agilis HCCI motor
Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.
Internetbegränsning på stadsbibliotek
The purpose of this thesis is to investigate how city librariesmaintain the intellectual freedom in their Internet service. Thediscussion about Internet filters has been quiet in Sweden forseveral years, so I wanted to see if there had been an increased useof filters. I also wanted to see if the city libraries regulated theInternet service in another way. I sent a survey to 100 libraries andgot answer from 83. To explain what intellectual freedom is, I usedStuart Hamilton?s theory about intellectual freedom in the librarycontext.
