The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

The objective of this study was to study the agreement between two methods of indirect bloodpressure measurement in dogs and cats and to establish the within-method variation for the methods. The utility and practicality in the clinical setting were also evaluated for the both methods. The techniques evaluated were the oscillometric method and the Doppler ultrasonographic method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.

The purpose of the present study was to study if the systemic blood pressure in cats significant increases due to stress associated with a visit to a veterinarian clinic. We also wanted to investigate the clinical utility of two different methods for indirect blood pressure measurements in cats by assessing how easy they were to use and how reliable measurements they provided. The methods that were used were oscillometric (Memo Diagnostic) and ultrasound-doppler technique (Minidop). The blood pressure was measured in both clinical environment and home environment. Fifty cats were used in the study, from which measurements were impossible to obtain in one cat.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

I denna uppsats har jag jämfört mottagandet i dagspressen av Agnes von Krusenstjernas roman Kvinnogatan och Karin Boyes roman Astarte. Syftet med uppsatsen var att analysera och jämföra hur två romaner av författarinnor som är kända för sina moderna och progressiva verk togs emot av en framförallt manlig kritikerkår. För att kunna göra det använde jag två teorier. Den ena är utformad av Gunilla Domellöf och tittar på hur kritiker, framförallt manliga, i allmänhet tog emot kvinnliga författare under det tidiga 1930-talet. Den andra, utformad av Tomas Forser, utgår istället från kritikern och handlar om kritikerns uppgift.

The purpose of this study is to describe and analyze four educators? views and experiences of working with children with Autism Spectrum Disorders in relation to the concept of "One school for all". Research has shown that a segregating perspective is dominant in the school system, but the education act says that all children have a right to an equal education.My starting point for this study has been the concept of term "One school for all" and the problems that can occur in working with children with Autism Spectrum Disorders. A school for all is a school where all children are welcome and where all children sees as equals regardless of what background or disability they have. This study will be important for newly graduated teachers who are not aware of Autism Spectrum disorders.

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

The parents of a developmentel disordered child live with much sorrow and anguish. Despite that, they often talk about hope, joy and love for their child. The autistic spectrum disorder includes different stands. Three of them are Autism, Aspergers syndrome and Disintegrative disability. An article overview has been made with the purpose to examine parents experiences of having a child that develops autism or a diagnosis within the autistic spectrum.

AbstractThe purpose of this study is to investigate teachers? views on play as a method for developing pupil?s communication and interaction in schools for children with severe learning disabilities. I am interested in pupils with autism spectrum disorder and their opportunities for social interaction with peers in playful activities. I focus on the subject communication and the parts about speech, conversation and interaction. My study is based on a qualitative study.

Background: Peripheral arterial disease (PAD), as a consequence of atherosclerosis in the arteria of the limbs, affects one of ten Swedes older than 65. PAD can develop slowly and silently, and involves an increased risk for cardiac infarction and stroke. Measurement of the patient´s ankle blood pressure and calculation of the ankle-brachial index is an evidence-based method to discover PAD. Objective: To investigate how district nurses and general practitioners perceive this method of examination and experience possible obstacles to why it is not more commonly applied at primary health care centres. Method: Data collected by semi-structured interviews have been processed by qualitative content analysis with a manifest onset.

The purpuse of this study was to develop knowledge about learning condition that are to be in a context of interaction with persons that have Autism Spectrum Disorder diagnosis are included. The pre-understanding has evidence in that the public very often has a lack of knowledge in understanding persons with this kind of disabilities that can put the social interplay in disharmony. The phenomenological approach was used to reach the essence of the learning influence processes. Seen from the respondents experiences of interaction as a help for the informal learning in a working context. The purpose was to see the result of interplay and the effect of learning condition and to see what help those respondents acctually have experienced.

Till resultatet valdes femton vetenskapliga studier.Resultat. Evidens finns för att följa blodtryck- och urinkontroller som påvisar förändringar i sjukdomen.

AbstractIn 2013, the diagnosis of Asperger?s syndrome will be eliminated as a stand-alone diagnosis, to be subsumed into the existing diagnosis of Autism Spectrum Disorder. In this paper, a study with the objective of emphasizing current opinions regarding the change in diagnosis is performed. Another objective is to examine the connection between identity and diagnosis. The study therefore targets people with a diagnosis, in this case Asperger?s syndrome.The empirical material of the study has been collected through a quantitative web-based survey.
