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 describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground Station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

The purpose of our study is to see how the interaction between the social services and police work when a child under 15 years is suspected of crimes.What happens to the child from an agency perspective? How is the experience for the child and how do they get their voices heard? How is the professional perspective for a child when a child is suspected of a crime? What do the various authorities for short-term and long-term measures for the child?We have chosen to do a qualitative study using semi-structured interviews. The study includes six interviews with two police officers, three field secretaries and a social worker in two different municipalities. A medium sized municipality, and a larger community.The people we interviewed think differently about collaboration. The municipality have different workforms.

 The aim of this essay is to examine if the Swedish Major labels are moving towards making their catalogue available on different platforms rather than their traditional distribution of music. The new technology has really stirred things up for the major labels and file-sharing has been a problem for a long time. The labels have a history of fighting new formats instead of embracing them and listen to what their consumers actually want. We have found that the majors now are in the leading edge of music distribution due to technology and that is a first. We have focused this essay on if the consumption of music has changed the distribution of it or the other way around and found that people have changed their ways of consuming music over the years and the labels have always been forced to adapt.

Denna uppsatts är ett kandidatarbete på programmet för Fysisk Planering på Blekinge Tekniska Högskola och omfattar 15 hp. Uppsatsen genomförs under utbildningens tredje år. Uppsatsen undersöker hur problem och konflikter med konflikter vid hantering av olika sorters trafiksystem på samma plats har skapat en problematisk trafiksituation i Bergåsa. Vilka aktörer som bidragit till att dessa konflikter uppstått undersöks, och hur dessa aktörer även begränsar platsens framtida utveckling. Detta genomförs genom en teknisk och historisk studie av platsen, kopplat till en analys av aktörernas påverkan på processen.

Den här uppsatsen försöker besvara frågan om hur man kan förmedla känslor, tankar och stämningar till människor med trädgården som medium. Uppsatsen söker även svar på om man specifikt kan designa gröna miljöer som riktar sig till människor som går igenom ett sorgearbete. Här ges exempel på flera olika designteorier och olika sätt att tänka kring hur man skapar meningsfulla landskap. Därefter presenteras forskning kring hur människor tar sig igenom ett sorgearbete och bemöter känslor av sorg. Uppsatsen tar även upp Appelton?s teorier kring habitat och prospect/refuge och hur människan förhåller sig till rummet. Vad som avgör vår känsla av trygghet och de underliggande mönstren i hur vi läser av vår omgivning. I den avslutande delen av litteraturstudien går jag närmare in på hur man kan skapa helande miljöer för människor som genomgår ett sorgearbete. I uppsatsen ingår även två utformningsförslag som är baserade på den tidigare genomgångna litteraturen kring hur man skapar trygga och helande miljöer.

The purpose of the study was to determine the attitudes of the teachers of Reggio Emilia inspired preschools concerning the science work with children between the ages of one and three, as well as their opinions on how the physical preschool environment and the choice of materials influence their scientific work. The study was conducted in three departments of two different kindergartens. Although both kindergartens called themselves Reggio Emilia inspired, their working methods and their environments differed largely. None of them were originally built as Reggio Emilia inspired preschools. One of the kindergartens strived to design their indoor environment the same way as the preschools of Reggio Emilia are constructed, there for they were setting up different Stations where the children themselves have the opportunity to explore various scientific areas.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting Stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.

Train travel has increased in Sweden, and future increase of train transports putdemands on the already vastly exploited railroad net. The increased need of capacitycan be seen in the ongoing and planned expansions of the railway track. One part ofthe railroad infrastructure which is affected by an increase of travellers is the design ofthe Station platform. Since the platform is the place where the traveller meets thetrain, dangerous situations can occur in this environment. A number of studies focuson single safety risks, albeit there is no research to show the full picture of safety inthe platform environment.This study aims to treat and put together a compilation of risks for the traveller in theplatform environment in the form of a checklist, which can be used as support inplanning and design of a safer platform environment for existing or planned platforms.The thesis has, through case studies of five ongoing projects within the NationalRailroad Administration (Banverket), interviews with train company personnel andinternational railroad administrators, identified and treated safety (and security) risksin the platform environment.The conclusion of the study is that the relations between the traveller, the physicalplatform environment and the project organisation are important to explore andexploit when designing effective safety measures.

Ambulanssjuksköterskor är sårbara när det gäller både kortvarig och långvarig stress då de efter en traumatisk händelse ligger i riskzonen för att utveckla en akut stressreaktion. Stressreaktioner kan ses som en normal reaktion för den som varit med om en traumatisk upplevelse. Många har lärt sig att hantera detta i sin arbetsvardag, men för en del utvecklas denna stressreaktion till att bli långvarig. Det är betydelsefullt för ambulanssjuksköterskor att ha strategier för att kunna hantera upplevelsen efter traumatiska händelser och därmed kunna förebygga långvariga stressproblem. Vårt syfte var därför att undersöka hur ambulanssjuksköterskor hanterar upplevelsen efter en traumatisk händelse.

This thesis is a study of residential environments and a design concept for a proposed housing area in Tierp. The industrial era created a need for the central planning of housing. The confined environments that arised in cities during the 19th century, together with modernistic and democratic ideas, led to regulations in planning and housing. Though the overall goal has been the same: to create a good standard in living, the ideas of how to achieve that have varied. The starting point for following generations has been to attend to the insufficiencies of the earlier planning periods.

We are soldiers, not policemen.Denna uppsats rör det vakuum som ofta uppstår när en regim faller samman på grund av krig, och dess ordningsmakt upplöses, eller av annat skäl inte förmår upprätta ordningen. Ofta inträffar plundring och upplopp i det ?polisiära? tomrum som inträffar från det att den tidigare regimens ordningsmakt drar sig undan, till dess att en ny poliskår träder in och bör-jar återupprätta lag och ordning. Av olika skäl frånsäger sig den intervenerande makten inte sällan arbetsuppgifter av mer ?polisiär? natur, alltifrån att bevaka samhällsviktiga byggnader till att dirigera trafik.I stor utsträckning följde kriget i Irak våren 2003 detta mönster från tidigare konflikter; ordningsmakten drog sig undan, plundring utbröt och koalitionen, bestående främst av USA och Storbritannien, nekade inledningsvis till att det var deras uppgift att ingripa mot laglösheten.

The company is currently in a stage of improvement and has therefore taken the help of students at School of Engineering, Jonkoping University. The current production is batch, production layout is fixed. A bottleneck is created after the first Station which leads to large efficiency loss.  The meaning of this report was to provide a layout suggestion with balanced workStations to a new production line. The conditions were that the production line would be one-way, driven by customers order and meet a demand of 40 products per week.

Vid prehospital patientkontakt är symptom och problem ofta tydliga, men ibland är det svårt att få en utförlig anamnes på grund av språksvårigheter eller medvetandepåverkan. Symptomen kan också vara diffusa och svårtolkade. Efter avlämnandet på mottagande enhet, vilket vanligtvis är en akutmottagning, finns det funderingar hos ambulansperso-nalen om vad som hände efteråt med patienten och om de kunde ha fått bättre prehospitalt omhändertagande. Syftet med studien är att beskriva ambulanspersonals behov av uppföljning av vårdade patienter.En enkät skickades ut till åtta ambulansStationer i Västsverige under våren 2008. Till-stånd från enhetschefen på respektive Station inhämtades och personalen fick frivilligt delta i studien.
