The use of spread spectrum signals has increased dramatically in military applications. Finding methods for detecting and positioning of these signals have become interesting research areas for signal intelligence purposes. One method is to measure the time difference of arrival (TDOA) that occurs when two receivers are synchronous and spatially separated. Based on the TDOA-technique an audio-demonstrator has been developed and implemented. This report describes the theory for how sound received in microphones can be used to extract information about the transmitter?s position from the measured time difference.

A geographical position and its social, cultural and political context as well as climate and specific physical characteristics define the scope for a landscape design project. This has become clearer for us in our master project where we have made a Design Program for the outdoor environment of Wollo University in Dessie, Ethiopia and analysed and reflected on the work and process. The aim for the project has been to design an attractive and functional outdoor environment for the Campus, based on the inventories and the needs and wishes of clients and users. But, the aim has also been for us as landscape architect students to gain a greater knowledge about landscape architecture and the design process by position ourselves outside our usual context. The method has been open and seeking where the site, literature studies, dialogues with people and our own experiences from the field study in Ethiopia has influenced the work. Wollo University is situated 400 kilometers north of Addis Ababa, in a mountainous landscape. It faces problems of heavy rainfall during the summer, soil erosion, a lack of essential facilities, and is still a construction site with empty spaces in-between buildings and infrastructure.

Att utforma gra?nssnitt och system da?r variationen mellan anva?ndares respektive anva?ndningsma?l, a?lder eller andra fo?rutsa?ttningar varierar, kan vara en sva?r uppgift och kra?va fo?rsta?else fo?r de ma?nga olika anva?ndarna. Fo?rbundet Svensk Bridge a?r en organisation med o?ver 26.000 medlemmar i a?ldrarna 10 till 90plus, och har sa?ledes ma?nga olika typer av anva?ndare, med olika fo?rutsa?ttningar och kunskap, fo?r att kunna ta till sig den information som finns pa? Fo?rbundets hemsida.I den ha?r fallstudien har det tillva?gaga?ngssa?tt av den designprocedur fo?r framtagandet av en prototyp pa? en ny hemsida a?t Fo?rbundet Svensk Bridge utva?rderats. Detta har genomfo?rts genom dokumentation av designproceduren under alla dess olika moment, och sedan genom en utva?rdering och ja?mfo?relse av designprototypen gentemot dagens befintliga hemsida.

This study aims at norming a new objective method to track and measure jaw movements in 3D (three dimensional) during chewing in the young adult population (n=41, age 22-30). Norm values of the range of movements and the duration were calculated. Intra and inter rater reliability was high. Masticatory efficiency among participants was evaluated with a two-colored wax, analyzed with picture analysis software. Regression analysis was used to calculate the relationship between movement and duration variables and masticatory efficiency.

This study deals with the contribution of the genetic variant lactase persistence among Neolithic people from the Baltic Island Öland. Skeletal remains from twelve individuals went through DNA sequencing in order to find the mutation that allows adult individuals to digest milk sugar. The twelve individuals were chosen from two different Neolithic sites, where the archaeological and isotopic data suggest that the individuals from Köpingsvik were hunters and gatherers and the individuals from Resmo were early farmers. The individuals with the genetic variant lactase persistence can be described with selection and genetic flow.  Only five individuals produced results and the mutation was found in two of the subjects. All the individuals who were successfully sequenced came from Resmo, whereasno individuals from Köpingsvik yielded any results.

Playfulness and curiosity in the usage of new technology and digital filmmaking has always been of great importance within these fields. There are many different media technologies that can form what the user wants to communicate in a certain context. One of these forms of expression that has increased in popularity from the early 20th century until today is the animation technique, Stop motion. Amateur filmmakers have also found an interest in using the technique. Our purpose has been to study the different aspects as to why young-adult amateur filmmakers have chosen stop motion as the way to express themselves.

The demands on the adult literacy-rate are very high in Sweden. People with reading and writing difficulties may find it hard to fit into the community and to succeed in school. To accommodate the needs of students with learning disabilities, Swedish schools provide easy-to-understand materials. The purpose of my thesis is to examine how easy-to-read textbooks for high school students are different from regular textbooks. The study was carried out using a content analysis and I examined the books according to criteria specified by the Swedish author Torbjörn Lundgren.

The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.

Syftet med studien var att undersöka sambandet mellan perfektionism och psykologiska färdigheter hos fotbollspelare. Studien utfördes på 207 fotbollsspelande gymnasieelever som alla gick någon form av fotbollslinje på respektive skola. Informanterna fick fylla i två stycken frågeformulär, Multidimensional Perfectionism Scale som mäter perfektionism och Ottawa Mental Skills Assessment Tool-3 som mäter idrottspsykologiska färdigheter. Resultatet analyserades med hjälp av statistikprogrammet PASW där korrelationer (Pearson) mellan sex dimensioner av perfektionism och tolv psykologiska färdigheter genomfördes. Resultatet visade att det fanns flera signifikanta samband mellan de sex dimensionerna inom perfektionism och de tolv psykologiska färdigheterna. .

Stress är ett ämne som det talas flitigt om i dagens samhälle. En hög stressnivå kan enligt tidigare forskning ha en negativ inverkan på vår hälsa. Syftet med studien var att se om det fanns någon skillnad i stressnivå mellan studenter som har extrajobb och de som inte har det. En av hypoteserna i studien var att studerande kvinnor har en högre stressnivå än studerande män. En enkät delades ut, Perceived stress scale (PSS), till 137 studenter varav 89 män och 48 kvinnor.

 This essay is about how the educators can use the play as a tool to develop childrens social skills with eachother. The work is based on a qualitative study using a survey, where the educators can tell how they work within the play. I chose to use five different participants in my essay. All of them work in the same preschool, south of Stockholm.In this essay I have two questions. These two are:What do the educators tell about the importance of play for children's interaction?How do the educators tell how they work with the play to develop the children?s social interaction?Previous research shows that play gives the children opportunity to develop socially, emotionally, intellectually and physically.

Tidigare forskning visar att individer med en diagnos inomautismspektrumet (ASD) upplever en större sinneskänslighet vad gällerhörsel, syn och känsel men få studier har undersökt lukt känsligheten. Syftetmed föreliggande studie är att få en djupare förståelse för luktfunktioner hosvuxna med ASD.16 deltagare med ASD (14 kontroller) testades iluktkänslighet, fri- och stödd luktidentifiering. Samtliga deltagaresjälvskattade även den upplevda luktkänslighet samt genomgick ettscreeningtest för autism, The adult spectrum quotient, AQ. Lukt känslighet,fri och stödd luktidentifikation skiljde sig inte åt mellan de båda gruppernaSjälvskattning av luktfunktioner korrelerade signifikant positivt med AQpoäng vilket visar att personer med högre grad av ASD också upplevde sigsom mer luktkänsliga. Föreliggande resultat påvisade att personer medhögre AQ-poäng upplevde att de hade en känsligare luktfunktion.

Bakgrunden till uppsatsen grundas i ett allmänintresse i hur organisationer som dagligen påverkar den enskilde medborgaren förändras. Efterhand blev vi mer intresserade av hur förändringen påverkat de som arbetar inom organisationen och hur deras möjlighet att påverka sin vardag har förändrats. Syftet med uppsatsen har varit att undersöka och diskutera hur mellanchefer på Försäkringskassans handlingsutrymme har påverkats under och efter en organisationsförändring. Vi har, utöver att titta generellt på handlingsutrymme, även fokuserat på hur kommunikation och delaktighet upplevdes under samma period. Metoden som användes var av kvalitativ/konstruktionistisk karaktär, eftersom vår tanke med studien byggde på att förstå relationen mellan relativt komplexa, mångfacetterade och subjektiva begrepp.
