Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

This report is a result of a bachelor thesis at the school of Architecture and the Built environment (corresponding to 15 HP) and is written during spring 2012 at the Royal Institute of Technology (KTH) in Stockholm. The Bachelor's essay is based on the design and dimensioning of a house which is located at a predetermined site in Malmo, Sweden.The idea is to construct a house that is appropriate to use for an average Swedish family of four family members. The house is designed in a modern way with respect to ease of access and disabled facilities. The installation that have been considered are heating, ventilation, sanitation and electricity. Construction calculations and material selection are also discussed.Furthermore, a study about photovoltaic cells has been done.

The purpose of this study was to bibliometrically investigate and describe the research area called ?extrasolar planets?. The research questions were: Which authors were mostly cited within the area when the first authors (and their co-authors) were considered? Which authors were found in most co-occurrences? Did particular author collaborations emerge? To which institutions were most authors affiliated and did the size of the institution have an influence on whether an author was cited? What was the geographic distribution of authors and institutions and were there any patterns of collaboration?Did the image of dominating institutions and countries depend on the viewpoint?How applicable was Lotka?s law on the collected data? The data was collected from citation lists in documents from the database Arxiv.org. The documents were extracted by using the search term ?extrasolar planets?.

This thesis represents my individual final research in Societal Risk Management. The aim of the study is to research whether the method called Responsible Beverage Serving has had the desired effect of diminished alcohol-related violence in Karlstad City, after its implementation into the ordinary operational agenda for Karlstad district in the county of Wermland. According to the method, the alcohol-related damages as well as alcohol-related violence in a society can be reduced by refusing to serve minors and clients who are excessively intoxicated.In order to be able to reach the aim of the thesis, the subsequent questions must be answered;Has excessive drinking reduced in the bars and clubs in Karlstad City?Has it become more difficult for minors to be served alcohol in the bars and clubs in Karlstad City?Has the police reported amount of assaults outdoors diminished regarding the alcohol-related violence in Karlstad City?This research is an intervention study and uses a quasi-experimental design. The intervention itself is the method called Responsible Beverage Serving.

We travel more to day than we have ever done before and there is an abundance of destinations to choose from. All -destinations have vantages and disadvantages and the things that are favourable for one traveller can be the opposite for another. So the questions are, why do we have different opinions about the same destination and what is it that makes us choose one destination before another?The purpose with this thesis is to investigate if the demographic factor age has an influence on the Swedish traveller?s opinion about winter destinations. The thesis also investigates if there is a link between the traveller?s demography and their opinion of a destination.

Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.

Scintigraphic examination of the esophagus has for some time been the method of choice for the study of motility dysfunction in humans. The method has not yet been described for horses hence the lack of reference values for passage time for a bolus through the esophagus in healthy subjects. The purposes of this study were to measure passage velocity and time for a bolus to pass through the esophagus in healthy subjects, as well as to evaluate the reproducibility of the method. Eight warm-blooded trotters were used in the study. The horses were sedated with a low dose of Acepromazine prior to onset of the study.

If you keep cattle in a herd outside all year round on big varying grounds, their possibilityto perform their natural behaviour increases. This way of keeping cattle requires that youprovide them with their other needs, like shelter and a dry and clean resting place.According to the animal welfare authority´s regulations on livestock farming, only animalsthat are suited to stay outside during the cold season are allowed to be kept outside. Theyshould also have access to a shelter or another building that gives them protection from theweather and wind and provides a dry and clean resting place.Research has shown that as long as cattle do not get exposed to precipitation and wind theywill manage low temperature well. Some of the things that will affect how well the animalshandle different climates are the isolation ability of the fur, the animals´ body size and thefeed intake. A dry lying place that is both insulating and moisture absorbent is also of greatimportance.

In this report we describe an adaptive simulated annealing method for sizing the devices in analog circuits. The motivation for use an adaptive simulated annealing method for analog circuit design are to increase the efficiency of the design circuit. To demonstrate the functionality and the performance of the approach, an operational transconductance amplifier is simulated. The circuit is modeled with symbolic equations that are derived automatically by a simulator..

The theologian Sarah Coakley has developed a theological method, which she calls théologie totale.This essay examines the methodological criteria for this method. To understand how its anthropology, epistemology and theology are shaped, the criteria are analyzed within a theoretical framework, in which mainly David F. Ford's theological typology and Stephen Bevans models of contextual theology play parts. The material consists of Coakleys texts, essentially the first part of Coakley?s projected systematic theological work.

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

Humor is as interesting as it is hard to define. It has travelled a long way since Hippokratestheory about body fluids and how someone, if lacking one of these, were called a humorist andwere laughed at.In this thesis we developed a new method for categorizing types of humor in Swedish comedyseries on TV. We chose six different shows (Grotesco, KvarteretSkatan, Morgonsoffan, Fredaghelaveckan, Parlamentet and Hjälp!) from the two most popular TV-channels in Sweden(SVT1 & TV4).We based or method on previous researchers? work and came to find some categories that wererepresented in most of the previous work. Our own method came to contain seven categorieswhich we believe is enough to obtain all kinds of humor in Swedish comedy series on TV.In our study we saw that most of the humor fell under the category that we called unnormalityhumor,a category which contained incongruity which many researchers believe is afundamental part of humor.Our opinion is that the unnormality-category became too wide in our study and that we perhapsshould have divided it into two or possibly three categories to see a more distinctive result.Nonetheless, our result offers an interesting starting point for future comparative studiesfocusing on similar subjects..
