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.

The history of Banu Umayya has since the collapse of the caliphate occupied a major part in Islamic historiography. The present thesis analyses the presentation of the Umayyads in Ibn Khaldun?s al-Muqaddima and its relation to previous historical traditions. The thesis examines the social and intellectual context in which Ibn Khaldun stood and how it is represented in his historiography, while also providing an overview of the various socio-political, intellectual and historiographical developments in Islam. The theoretical perspectives are based on the concept of agency, examining the intellectual room for manoeuvre that the historian disposed of while composing the works.

The aim of this study was to gain understanding and knowledge about first line manager?s need for support in their leadership and to get more insight into how they handle and perceives their work.The research method is based on studies of relevant theories and qualitative interviews. Eight respondents were interviewed with a structured 40 question questionnaire about how they experience their work and the support they get. The study shows that there are three important categories of people that are most significant to the managers in their need of support. They are their own manager, colleagues and co-workers.The conclusion is that it is important to create conditions for leaders to have good relationships with their closest manager, colleagues and co ?workers.

Hälsosamtal med elever i skolan är ett arbetssätt för att främja barns hälsa. Studiens syfte är att beskriva förutsättningar för ett bra hälsosamtal utifrån ungdomars perspektiv. 16 individuella intervjuer med ungdomar på högstadiet och gymnasiet genomförda inom ramen för ett större forskningsprojekt har analyserats med kvalitativ innehållsanalys. Resultatet visar hur ett elevcentrerat, tryggt och strukturerat hälsosamtal skapar förutsättningar för lärande, reflektion, motivation, relation och delaktighet. Ungdomarna uttrycker önskemål om ett elevcentrerat hälsosamtal, anpassat efter deras individuella behov och önskemål.

The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.

In Sweden the most common type of road traffic accidents involving passenger cars are single accidents (where only one vehicle is involved). The aim of this thesis is to analyse how these accidents occur, and present recommendations on how to reduce the number of deaths. Data has been collected from the Swedish Transport Administration?s in-depth studies of fatal accidents. Road traffic accidents with fatal outcome that happened on public roads during the years 2007 to 2009 have been studied.

Background: ?Transitional care? is a new form of care in the Child and Adolescent Mental Health Services (CAMHS) in Sweden. The level of care, between outpatient and inpatient, has been developed to meet children/adolescents and their families in a different way than in the traditional outpatient and inpatient treatment. The contact offered can be intense with frequent contact and also with more time set aside for every occasion. The nurse, who is one of the categories of personnel involved in the multidisciplinary team works largely in other contexts than in the therapy room at the clinic or on the ward.

Today, companies can take advantage of mass intelligence by making use out ofcrowdsourcing. Crowdsourcing is a business model that uses the power of the collective bythe offer of a problem by means of competitions in various social media. The benefit ofcrowdsourcing is that the company gets more creative and creative solutions to the sameproblem, which would not have been possible if the company solved the problem internally.The larger mass gains an insight into the company, which in return also releases power tothe company's development. The study aims to examine the way in which citizens can beattracted to participate in the development of public transport using crowdsourcing. The studyis based on both qualitative and quantitative approach since the study has a qualitative pilotstudy.

Anna Maria Lenngren (1754-1817) is known as one of Stockholms Posten?s sharpest satirists. Over the years many literature researchers have based their analysis and interpretations on biographical facts. This means that we miss important parts of her authorship, as she almost exceptionally has been writing role-poems. In a role-poem, the author takes a role as a fictitious narrative subject and/or another poem character.

In addition there arecalculations done on the building?s energy management.The result is a two stored house angled toward the south.

The purpose of this study is to describe some primary school teachers understanding of language development and approach of first and second language speakers with Arne Tragetons Writing to reading, for pupils in early ages.By using a qualitative method with interviews and participant observations and informal conversations, the basis for the survey was collected. Four teachers in three schools participated. The proportion of second-language pupils at each school was 35%, 17% and 0%. My theoretical starting point in the study was the hermeneutic research tradition, which has been used to interpret and understand the collected material. Theories of behaviorism, constructivism and socio-cultural perspective has been used in the analysis part of this study.

This report is the result of a project in the course Independent Projekt in Molecular Biotechnology at Uppsala University during the spring of 2014.
