AUTOMATISK PAN/TILT-KONTROLLER FÖR ANTENNINRIKTNING
This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth.The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle.By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit.The control unit will sense its own direction by a magnetic sensor that works as an electronic compass.
Disciplinär eller curlingfostran : En kvalitativ studie om vilka strategier fyra mödrar använder sig av för att fostra sina barn
The vast majority of parents want their children to succeed and become successful in one way or the other. The very first is that the child will graduate from school. In today?s society which is characterized by career-driven parents, especially mothers, one wonders if somewhere along the way parents are prioritizing their own careers over their children?s school achievements. This might be true in some cases, but in others it could merely be that parents are expecting more from their children?s future.
Matte är mer : Elevers uppfattningar om matematikinlärning
Syftet med studien är att utifrån ett elevperspektiv beskriva och analysera elevernas lärande i matematik, syftet med ämnet, vilka strategier de använder samt hur de uppfattar sin delaktighet i undervisningen.Utifrån ett elevperspektiv använde jag mig av en kvalitativ metodansats. Det empiriska materialet som studien bygger på består av enkäter med öppna frågor och semistrukturerad intervjuer. 41 elever i år 5 och 6 deltog. Med utgångspunkt i insamlad empiri gjordes en tematisk analys.Av resultatet framgår att eleverna tar ett stort ansvar för sitt lärande och beskriver vikten av matematiken i vardags respektive vuxenlivet. För många elever är matematikinlärning ett självständigt arbete med ständig träning av procedurer i ett kontextreducerat arbete.
Walking area with something for everyone : En studiekring besökarnas syn på Södra Djurgården
This essay will examine the visitors' view of destination South Djurgården and the impact that tourism provides in them. South Djurgården belongs to Stockholm where the boundary between the southern and northern Djurgården is Djurgårdsbrunnsviken and Djurgårdsbrunnskanalen. The reason we chose South Djurgården is because the biggest and famous attractions of Stockholm are there. In this essay we have used a combination of qualitative and quantitative methods. We conducted the survey through questionnaires and deep interviews.
Tryckpulsgenerering för funktionskalibrering av mätsystem
The running of gas turbines with low emissions causes high pressure pulsations to arise in the combustion chamber. These pulsations are high amplitude sound vibrations. At some frequencies these are harmful to the gas turbine. Hence these pulsations are monitored to avoid operating conditions where pulsations are specifically harmful. It is necessary to expose the system of known pulsations to verify the functionality of the monitoring process.
När trädens rotsystem får bestämma : En intervjustudie med en grupp yrkesverksamma inom anläggning av hållbara gröna miljöer.
ABSTRACTThis pilot study examines the knowledge about tree root systems amongst five treeplanting professionals. The aim is to find out the professionals? collective knowledge ofthe nature of root systems of various trees used in green areas. Furthermore; to explorehow the professionals adapt landscaped green areas to the tree root properties in asustainable manner. Questions: Which tree species have special root properties toconsider and how do the professionals utilize this knowledge? And: How do theprofessionals in general adjust planting according to the root systems of trees in areas tocreate sustainable green environments?Interviews with the professionals were performed.
Sjuksköterskans roll i omvårdnaden av patienter med suicidala tankar
Nurses have an important role caring with the suicidal patient as they often are the first to encounter these individuals. In order to develop their skills, nurses need to understand the complexity of the problem around the thoughts of wanting to die. The purpose of the study was to compile and elucidate research that describes how nurses can provide care to suicidal patients. The method used was a literature review. The results were divided into seven themes that can guide the nurse in the work: to be there, give time and listen, to recognize and assess risk factors, working in a team, to be attentive to own attitudes, to give hope, to be able to process their feelings, increased knowledge of the causes of suicide.
Självförvaltningens effekter i vår gemensamma utemiljö
When we, in the turn of the year 07/08 moved to Holma, Malmö,I and my cohabiter immediately joined the self-managementon our tenement yard, partly because we both missed havinga garden since we moved to an apartment, partly becauseof the rent reduction. The aim with this thesis is to examinehow the common outdoor environment in tenement yards isaffected when the tenets themselves are responsible for themaintenance. But also to see what social affects self-managementbrings. The purpose is to increase the understanding of howself-management works in practice and how we as landscapearchitects need to adjust ourselves and our design to create alasting design that works when the tenets are in charge of theirown outdoor environment.I have been studying a number of tenement yards with selfmanagement,both municipal and private tenement houses. I havestudied both their design and their self-management, how it isworking and how it is organized partly trough deep interviewsand also by questionnaires to the tenets of the yards in question.I found three tenement yards with some differences.
Radiella vikter i Rn och lokala dimensioner
Kapaciteter kan vara till stor nytta, bland annat då partiella differentialekvationer ska lösas. Kapaciteter är dock i många fall väldigt svåra att beräkna exakt, speciellt i viktade rum. Vad som istället kan göras är att försöka uppskatta kapaciteterna, vilket för ringar runt en fix punkt kan utföras med hjälp av fyra olika exponentmängder, underline{Q}_0, underline{S}_0, overline{S}_0 och overline{Q}_0, som beskriver hur vikten beter sig i närheten av denna punkt och i viss mån ger rummets lokala dimension.För att kunna dra nytta av exponentmängderna är det bra att veta vilka kombinationer av dessa som kan förekomma. För att få fram nya kombinationer använder vi olika sätt att mäta volym av klot med varierande radier. Dessa mått är definierade genom olika vikter.Det har tidigare funnits ett fåtal exempel på hur olika kombinationer av exponentmängderna kan se ut.
Kim Jong Il - Docka eller dockmakare?
This paper has bearing on the subject of foreign policy analysis and decision-making,but is nonetheless important to peace and conflict studies due to its emphasis onnuclear weapons and deterrence.I have constructed a theoretical framework for the analysis of foreign policydecision-making that I set out to test on a crucial case. The framework iscrosscutting, and takes into consideration four levels of analysis: the system-,regional-, state-, and individual level. It is centred on a key decision maker, andapplies a cognitive approach for determining his or hers belief system through whichthe inputs from the other levels are filtered in order for the decision maker toconstruct a perception of reality, from which the decision is then formulated within.The framework is applied to North Korean and its leader Kim Jong Il. It sets outto explain his behaviour in the matter of their claimed nuclear weapons program, andhis decision to conduct a nuclear weapons-test, getting inside his head trying to figureout why he chose to do it and for what reasons.The conclusion indicates that the basic structure of the framework and its generalapplicability is sound, but that it needs further testing in order to make it perfectly solid..
It's Hard to Be a Cowboy So Far from the West : Trender i sångtexternas språkval, tematik och författarskap i Mats Rådbergs och Rankarnas skivutgivning 1969-2002
Tidigare forskning har fokuserat på emotionellt arbete i form av bland annat "surface och deep acting", emotionell dissonans och kundinteraktioner. Denna studie ämnade besvara frågeställningen: Har ålder respektive yrkeserfarenhet samband med en SJ AB anställds grad av emotionellt arbete i kundkontakter? Urvalet bestod av 65 anställda från ett flertal SJ Resebutiker i Sverige. Resultat visade att äldre anställda och anställda med längre yrkeserfarenhet hade ett starkare samband med krav och välmående på arbetet. Detta visar att det alltså är de som klarar emotionellt arbete bättre.
Konstruktion av specialmaskin för orientering och positionering av nyckelämnen
The thesis in product development ? mechanical design includes 15 credits and was carried out during the spring of 2014 at Semcon in Eskilstuna. The task is to construct a special machine for positioning and orientation of a key blank found in six different shapes, the construction is a part of a larger machine for encoding the key blank where a pick- and-place device or robot pick up the key blank and deliver it further in the process. The entire construction is designed for ASSA OEM Gothenburg.In order to accomplish the project the first step was to analyze the existing solutions to similar problems on the market in a current situation analysis to create an understanding of the problem. This was followed by a flow analysis and a functional analysis to get a deeper understanding of the problem and structuring the machine's process flow and its features.
