Utveckling och implementering av ett audiopejlsystem baserat på tidsdifferensmätning
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.
Första mötet med förskolan : en kvalitativ studie om olika inskolningformer på fyra förskolor
This is a qualitative study with four interviews, in four different preschools, in the same municipality. By making it so, it becomes a case study to describe a phenomenon in a municipality which also is the definition for this investigation. The purpose of my study is to examine what it means, in a municipality, to have different types of introduction at preschool. Where I ask the question why preschools choose to have a specific method of introduction and what are the basics and ideas behind the choice of the method? What significance do these different methods have to attachment theory? What do teachers think about the advantages and disadvantages with their choice of method?The versions of introductions are many and may vary; the duration of the introduction may vary from 1-3 days up to 3 weeks.

Jämtländska pedagogers erfarenhet av att ta emot flyktingbarn i förskolan
In recent years, the demands for effectiveness and evidence in social work have increased in all work areas, including that of healthcare. This has sparked the discussion on concepts such as practical- and theoretical knowledge and their respective roles in social work. In the light of this, the purpose of this candidate thesis is to investigate healthcare social workers understanding of practical- and theoretical knowledge in the working process as well as their respective influence and importance. This candidate thesis is based on three interviews with social workers from different departments in Norrlands Universitetssjukhus in Umeå, Sweden. To provide range to the thesis, the interviewees were chosen from a purposeful sampling.
Ett mynt har alltid två sidor? : En jämförelse av polisens förebyggande metoder mot ungdomsbrottslighet
How do the police prevention methods work against juvenile delinquency? The purpose of this study is to see how the police work to prevent juvenile delinquency in two municipalities in Stockholm, Södertälje and Sundbyberg. Additionally, the purpose of this study is also to find out if there are any similarities or differences between the police methods the police use in these two municipalities. We have used qualitative method in which we have interviewed the police and young people from the communities. We interviewed young people to see their attitudes to the police and the area to find their perception of police work in the fields as well as the police forces attitude toward the young people.
Identifiering av deponerat material i en deponi samt metodikförslag för upprättande av vattenbalans.
Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.
Det hemsökta vardagsrummet : Gestaltning och förmedling av ockulta fenomen i TV-serien 'Most Haunted'
In the 19th century, photography was often employed in attempts to objectively capture evidence of paranormal phenomena. With the advent of television, this tradition came to be coupled with the apparent mystery of distant communication through electromagnetic waves. The television set has often been depicted as intrinsically occult or even haunted.It is therefore natural that television has proven to be an ideal medium to present beliefs, tales, and investigations about paranormal phenomena. Most such presentations have been openly ficticious, but in television the distinction between fact and fiction is often blurred, and the emergence of shows where the crew claims to pursue a serious investigation was inevitable. One of the most successful such shows is the British Most Haunted, airing since 2001.
Att utföra kravprioritering med kravprioriteringsmetoder - en studie om dess genomförande och hinder under
Prioritisation of software requirements is a critical part of the development of software. Whichrequirements and in which order they will be developed is one of the main tasks that requirementprioritisation supports.There are different ways that a requirement prioritisation can be used, for example alone or in agroup and with different methods.The purpose of this report is to map out how you can carry out a requirement prioritisation alonewith different types of prioritisation methods and how you solve the problems that can arise whenprioritisting requirements. This is done by documenting the use of three different types of methodsthat can be execute alone. The methods are "100-dollar test", "Ranking" and "Top-tenrequirements".To be able to prioritise requirements, you need to establish which requirements you shall prioritise.The paper retrieves this information by interviewing stakeholders in the system and analysing theresult of the interviews and the execution of the requirement prioritisation.Three problems arose during that work and I present solutions on these problems. The problemswere 1) equivalent requirements when using the "100-dollar test", 2) low differentiation gradebetween the prioritised requirements in the "100-dollar test" and 3) that the requirements that wereprioritised weren't classified before the prioritisation, which leads to inaccuracies in the resultingprioritisation.The solution to the problems that the paper presents is to increase the amount of distributable unitsin the "100-dollar test" to 1000 per requirement, suggestions of classes of the requirements andthe combination of the methods "100-dollar test" and "ranking" to bypass the equivalentrequirements.The report is written in Swedish.Nyckelord: GoTRIS, requirements retrieval, requirements analysis, Viktoria Swedish ICT,requirements prioritisation, requirements, 100-dollar test, ranking, top 10 requirements..
Quantitative thermal perception thresholds, comparison between methods
Skin temperature is detected through signals in unmyelinated C-fibers and thin myelinated A?-fibers in the peripheral and central nervous system. Disorders in thin nerve fibres are important and not rare but difficult to diagnose by the most common neurophysiological methods. In this pilot study different methods for quantitative sensory testing, QST, were compared to give some ideas about which method could be the most efficient to use in order to point out injuries of the sensory system in clinical practice. The comparison was made between Békésy (separate warmand cold thresholds) and Marstock test (combined warm and cold thresholds).
Kronandelsrelaskopering, en ny metod för att fastställa gallringsbehov?
In today´s forestry, assessments of needs for thinning are based on basal area measurements. This is an indirect measurement. The approach and the developed assessment tables are based on an assumed production forest, which implies that management proposals in stands that deviate from the basic model may be misleading. Since Walter Bitterlich in 1948 launched the idea of the relascope, several modifications have been developed for different purposes. In common is that all are based on a certain angle measurement principle.
En j?mf?rande studie mellan tv? v?treng?ringsmetoder p? papper
Amongst the published literature researching wet cleaning of paper there is a limited amount of
studies conducted researching the method simmering water treatment. There are even less studies
conducted on how simmering water affects the paper being treated when used as a cleaning method.
Despite the limited research, there are literary reviews describing the method and suggesting it as an
alternative for conservation of paper with iron-gall ink. The following study will therefore be
examining, the somewhat unusual method, simmering water treatment, and comparing it to one of
the more common wet cleaning methods: immersion washing. This is done to compare how the
different temperatures of the water affect the paper.
The types of paper used in this study consists of three dyed and four undyed papers. All of the papers
are new, apart from one sample originating from 1847.
Utvärdering av AP-fonderna : En studie av AP-fondernas riskjusterade avkastning åren 2003-2009.
The general pension supplement introduced in 1960 which introduced the public pension funds in Sweden. In the late 1990s the Swedish pension system was reformed and established the current structure. Today, funds are one of the most common forms of savings in Sweden and mutual funds are the most common type.The purpose of this study is to analyze the risk-adjusted returns for the AP funds in the period 2003-2009. Study was based on five funds that are most similar and have the same mission. These funds are AP1, AP2, AP3, AP4 and AP7.The method used in this study is mainly based on a survey of the figures and measurable units of statistical methods that have been carried out by a quantitative approach.
Metoder att förhindra nedisning av vindkraftverksblad
ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.
Hur formas ett inlärningsklimat som är framgångsrikt över tid? : En observationsstudie om fotbollstränares beteenden och träningsaktiviteter
Aim and research questionsThe over-all aim of this study was to gain insight info how two male coaches of a specific soccer team behave in a practice environment with regards to educating the players.More specifically, the study sought to map the extent to which said behaviour matched two specific methods of learning; these being Teaching Games for Understanding (TgfU) and Enhanced Guided Discovery (EGD). Research questions: (1) Do the coaches employ the methods and guidelines, which are outlined in the educational plan provided by the soccer association? If so, what form does this application take in practice? (2) To what extent and in what ways do the coaches utilize feedback and questioning techniques in the education of players? (3) What similarities and differences in behaviour can be identified between the chosen soccer team?s two coaches?Method: The data for the study was collected through field observation. The subjects were two youth elite soccer coaches and observation of these coaches took place during five regular practice sessions on the soccer field. All data gathering and analysis were carried out using a modified version of the Coach Analysis and Intervention System (CAIS).
Skriftspråksutveckling i förskoleklassen
The aim of this essay was to investigate how teachers in the preschool class work with literacy. How do they justify the methods used to develop children's literacy abilities? I also wanted to know to what extent teachers enable multimodal approaches within written language practices. My study considers the impact teachers' professional identity has on working methods in the preschool class. I hope this essay will help teachers reflect on their learning approach.
I gathered information by interviewing three preschool teachers and one compulsory school teacher for the early years working in three different preschool classes in three different schools.
