Bearbetning av GPS-data vid Flyg- och Systemprov

At Flight and Systems test Saab AB, a post-processing software is used to process GPS data. A new software by the name GrafNav has been purchased and the purpose of this master thesis therefore became, partly to make a judgment regarding GrafNav?s ability to estimate position, velocity and accuracy, partly to if needed improve the estimate and finally find one or several methods to estimate the position and velocity accuracy. The judgment of GrafNav was performed partly by a comparison to the former post-processing software (PNAV) and partly by a comparison to the airplane?s inertial navigation system (INS).

Internetbaserade distansutbildningar

In the informational age of today, continuous learning is of greatest importance. The demand for this seems to be increasing, while at the same time people are under more pressure to carry out more tasks in shorter amounts of time. A way to solve the problem of finding time to learn could be to make use of the possibilities that Internet offers for learning at a distance. The purpose of this thesis is to, from a pedagogical perspective, contribute to the discussion concerning Internet based distance education for a target population consisting of professionals. We have found that some of the courses included in the two certification programs which we have investigated are suitable for Internet based distance education.

Att mäta fattigdomsbekämpning - En studie av social performance-rapportering inom mikrofinans

This study has a double purpose. First, it explores and maps out the use of quantitative key indicators in social performance reporting within a microfinance portfolio. This was done on behalf of Storebrand Asset Management, who would like to aggregate and report the social results of their microfinance investments to their customers. The study concludes that the extent of social reporting and types of indicators used varies, meaning that it is hard to aggregate data for use in further reporting. Thus, the work towards the goal of social reporting has only just begun.

Adaptiva metoder för systemidentifiering med inriktning mot direkt viktoptimering

Direkt viktoptimering (Direct Weight Optimization, DWO) är en ickeparamterisk systemidentifieringsmetod. DWO bygger på att man skattar ett funktionsvärde i en viss punkt genom en viktad summa av mätvärden, där vikterna optimeras fram. Det faktum att DWO har en inparameter som man måste veta i förväg leder till att man på något sätt vill skatta denna inparameter. Det finns många sätt man kan göra denna skattning på men det centrala i denna uppsats är att skatta inparametern lokalt. Fördelen med detta är att metoden anpassar sig om till exempel systemet ändrar beteende från att variera långsamt till att variera snabbare.

Reglering av turbins ledskenor i vattenkraftverkmed hjälp av elektriska ställdon

Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.

Val av överlastskydd för elektriska ventilmanöverdon på kärnkraftverket i Forsmark

At nuclear power plants, electrical valve actuators are important for ensuring that the reactor core is water covered and the pressure in the reactor tank and containment is limited. The electrical actuators are provided with overload protection in case of drawing higher current then the motors are rated for. When safety manoeuvres are needed, the overload protection must not trig and cause the valve to stop before completing the manoeuvre. Analyses have showed that the current settings of the overload protection may cause an illegitimate trig at the worst theoretically possible accident. A new method has been developed with conservative assumptions and applies overload protections for all electrical valve actuators at the three reactors in Forsmark..

Det Omedvetnas återkomst : En tvärvetenskaplig litteraturstudie i fältet mellan psykoanalys och neurobiologi

There are differences today amongst psychoanalysts regarding if psychoanalysis should limit itself to being exclusively a hermeneutic discipline or if psychoanalysis should find points of contact with neurobiology. The purpose of this essay is to touch upon the larger issue that creates the different points of view: Can psychoanalysis become enriched by finding points of contact with neurobiology, and should psychoanalysis be regarded as belonging to a broader scientific field than being exclusively a human science? The question at issue is: Can modern neurobiology contribute to a development of the psychoanalytic concepts; compulsion to repeat, transference/countertransference and talking cure? The method used is a literature study. The result shows that: Freud?s theories regarding traumatic compulsion to repeat can be linked with LeDoux?s theory of "emotional memory".

Skärgårdskvinna under efterkrigstiden: en studie om levnadsvillkor i förändring

Den här uppsatsen handlar om levnadsförhållanden bland kvinnor som är eller har varit verksamma inom någon skärgårdsbunden näring i Norrbottens skärgård. Den fokuserar på de förändringar som arbetsförhållandena och det sociala livet genomgått under perioden från andra världskrigets slut fram till idag, 2006. Jag, som forskare och uppsatsförfattare, har försökt nå denna kunskap genom att söka svar på frågor om hur kvinnornas ställning har förändrats i arbetet, i familjeförsörjningen och i det sociala livet. Metoden som använts är kvalitativ och baserad på semistrukturerade intervjuer och kategorianalys av citat tagna från intervjutranskriptionerna. Teorier som använts är Due Billings och Alvessons kritiskt tolkande perspektiv på genus/kön, samt Zollinger Gieles och Holsts omarbetningar av Talcott Parsons begrepp adaptive upgrading, integration, inclusion och goal differentiation.

Effekt av ACE-hämmare på incidens av hjärt-kärlsjukdom och mortalitet hos diabetiker typ 2 samt av diabetes hos hypertonipatienter.

Background: Diabetes mellitus is a chronic disease that manifests as an increased level of glucose in the blood. According to the World Health Organization (WHO), 347 million people have diabetes worldwide. In year 2004, 3.4 million people died from the consequences of high blood glucose. In the Swedish population the prevalence of diabetes is estimated to 3-4 %, out of which 85-90% are Type 2. Among senior citizens a prevalence of diabetes is seen in Sweden up to 14 - 15%.

Preventiva trycksårsåtgärder. En litteraturstudie

Trycksår kan förekomma på alla typer av vårdavdelningar och tar lång tid att läka samt är en stor kostnad för samhället. Syftet med litteraturstudien var att undersöka åtgärder för trycksårsprevention. Metoden är baserad på en modifierad version av Forsberg & Wengströms modell för en systematisk litteraturstudie. Sökning i databaser PubMed och CINAHL utfördes och resultatet i litteraturstudien grundades på nio kvantitativa vetenskapliga artiklar. Författarna kunde identifiera olika preventionsåtgärder där framför allt evidensbaserade bedömningsinstrument som Modifierad Nortonskala och MNA-SF är viktiga att använda i trycksårsprevention, men även temperaturmätning, ?Continental anal plug? (CAP), god nutrition, aktivitet samt tryckreducerande underlag som fårskinn..

Kirurgi vid Superior Canal Dehiscence Syndrome ? En beskrivande litteraturstudie om audiologiska och vestibulära resultat och komplikationer

Superior Canal Dehiscence Syndrome (SCDS) is a newly described syndrome with symptoms including sound- and pressure induced vertigo, conductive hyperacusis and autophony. SCDS is caused by absence of bone overlying the superior semicircular canal and can be surgically treated. As the syndrome and surgical technique is new, it is of importance to study possible postoperative outcomes..

Lokal samförvaltning i Tivedsbygden : en svårfångad vision om hållbar naturresurshantering

Föreliggande kandidatuppsats handlar om att söka beskriva samverkan och konflikt i samband med naturresurshantering. Undersökningens forskningsobjekt är ett försök till lokal samförvaltning som togs av lokala invånare i Tivedsbygden, en skogsbygd i gränslandet mellan Västergötland och Närke. Visionen om detta hållbara naturresursarrangemang lyckades dock aldrig nås. Initiativet togs i samband med ett landsbygdsutvecklingsprojekt pågick under åren 2009-2011. Min tolkning är att detta försök präglades av samverkan och konflikt.

ST-läkares identitetsarbete: En studie av läkare under specialiseringstjänstgöring

The results from 13 interviews and one opinion poll answered by resident physicians were interpreted as stories about identity as primary material for this thesis. The resident physicians stress the importance of considering whether their work primarily concerns curing people from diseases or if the process of working with sick people also includes how to handle the pressure of work, either by adapting to it or changing it, and the search for balance between work and private life. Residents separate themselves from older physicians by saying that younger physicians accentuate empathy to a greater extent while older physicians emphasise a high work load. Identity seems to effect how the residents perceive and relate to their work, themselves as residents and different types of patients..

Studenters förhållningssätt till valet av framtida bank

Since the middle of the 1980´s the Swedish bank market has experienced a change concerning structure and pressure of competition. Before the year 1985, the market was characterized as a market with few operators but have changed to a market with many operators and seen as one of the most intense in Europe where the four major banks; Nordea, Handelsbanken, SEB and Föreningssparbanken together have a strong position. Their market share has recently decreased, mostly for the benefit of foreign banks and niche banks. The Swedish market has experienced difficulties in generating profits which mostly depends on new establishments that have increased the pressure on competition, a low growth as well as weakened customer relations. The development has resulted in a growing importance of market segmentation, mainly by the fact that costumers have become more disloyal as a result of the increased competition.Students are a market segment of interest for the financial market, mainly because of the expectations of their positive financial situation in the future.

The effect of hoof trimming on dairy cows´ behaviour, locomotion and production

The Swedish dairy production today consists of big farms and different housing systems are in use. These systems put demands on the cows? ability to cope with the environment and one challenge is the claw health in the herds. Some claw lesions that are frequently observed are foot rot, hemorrhages, digital dermatitis and sole ulcers, which can be caused by, for example, the claws? environment and the flooring type used.
