Konstruktion av radiokontrollerad klocka
Uppgiften var att ta emot och avkoda en radiosignal för tidsangivelse, DCF77. Avkodaren implementerades i en FPGA-krets från ALTERA. Utvecklingen genomfördes i Quartus II-miljön med språket VHDL samt en alternativ lösning där mjuk processor användes. Både utvecklingsmiljön och språken var väl lämpade för uppgiften. Ett genomgående problem var dock radiomottagaren ofta levererade för svag signal för att kunna avkodas korrekt.
Puritanismens dygdetik : En jämförande studie mellan Max Webers dygdteori och dygderna i John Bunyans bok Pilgrim´s Progress
The purpose of this study is to find the virtue ethics John Bunyan presents in Pilgrim´s Progress part 1, compared with the virtues Max Weber presents, and then try Weber´s theory on the empirical data, Pilgrim´s Progress. When I compare the virtues in Weber´s theory with the virtues in Pilgrim´s Progress, I interpret Weber´s theory as limited. From Weber´s theory emerges the puritan virtues: fulfillment of duty, struggle, self-control and live simply. He also mentions gratitude to God and helpfulness to other people, but this is shown through work in the society. These virtues can also be found in Pilgrim´s Progress.
Rättfärdigade argument? USA:s militära intervention i Panama 1989
In 1989 the United States choose, after years of conflict, to carry out a military intervention in Panama, to remove Manuel Noriega, convicted for drug dealing and for threatening the lives of the Americans living in Panama. The aim of this study is to examine whether George H. W Bush?s arguments for the military intervention comply with the principles of the just war.The method chosen for this study is a qualitative literature study, based primarily on secondary data. It is a case study with two complementing theories, the theory of the just war and the world system theory.The result showed that the American intervention both can be justified and unjustified following the principles of the Just War Theory.
Går det att stympa kärlek? : Den liberala och radikala feminismens syn på kvinnlig könsstympning i Etiopien
The purpose of my work is to understand and examine the reasons why Ethiopia has not developed a larger decline of female genital mutilation, despite their ban on it? A ban that has been operating for ten years should reasonably have reached a greater change than the one Ethiopia has developed today. Based on two different branches of feminist theory, the liberal feminist theory and radical feminist theory, I will try to understand the potential power relationship that can be a immense reason for Ethiopia's continued practice with regard to female genital mutilation. I will examine the liberal feminist approach when it comes to seeing the state as the source of the balance of power that generate inequality in the world between men and women. I will also apply the radical feminist theory on my case study and understand the problem of patriarchy and its already set roles for men and women that we are following in the society today, resulting in gender inequality. The result shows that the radical feminist approach with patriarchy as essential explanation, which articulates that because of ancient traditions and the exercise of power, the amendment must be the changing of power relations between men and women in the private sphere rather than the liberal feminist approach which applies that the state repair the problem..
Utvärdering av en FPGA för rymdbruk
A new FPGA suitable for space applications has just reached the market. To investigate whether there are any possible flaws or limitations similar to those previously seen on FPGAs, an evaluation has to be done. This master thesis contains the evaluation of this new radhard FPGA with focus on possible design limitations and package related electrical phenomena.Areas evaluated: Ground-/VDD bounce, Cross talk, Rise time sensitivit, Power cycling, Power consumption, Place and route tool, Radiation hardnessThis report contains all steps in the evaluation. From method to measurements, comparisons, theory, results and conclusions. In the evaluation work, special effort has been made to develop designs that really stress the FPGA to find potential problems.
Regimteorin i svensk kontext. Från Volvo till IKEA i Kalmar
The regime theory is the dominant paradigm in the studies of urban politics in USA. It provides a set of concepts to analyse the change from government to governance in the American local politics. The regime theory postulates that governing power in local government tends to be highly fragmented. The private sector has with its control of economic resources a major influence in shaping governing decisions. In this essay I study the regime theory in a Swedish context to investigate if the theory is pertinent when studying of Swedish local governance.
Utveckling av analysmodul till Zenicor Medical Systems EKG-system
The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition..
Lågoffsetkomparator
Detecting small signals with a comparator demands that the total voltage offset is lower than the actual signal. The total offset includes the voltage offset in the comparator and the voltage offset that is created by the offset currents that flows thru the load at the comparators input. The goal with this comparator that has been developed has been that it will have a total voltage offset at maximum 500 uV. The comparator does not need to be extremely fast or does not need to operate in a big frequency area. To have all the flexibility that is needed a full custom technique is used.
Arbetskraftsinvandring -en problemorienterad studie av SAP: s hanterand av arbetskraftsinvandringsfrågan
The aim with this paper is to investigate how the Social Democratic Party (SAP) deals with the question of economic migrants, or more specifically how the problem is represented by the Social Democratic Party, and how this representation has developed over time. The SAP's theory became recently contested by a competing theory that was caused by the predicted future demographic development in Sweden, combined with the EU's eastern expansion. The first factor contributed to the re-write of the theory, to a theory that saw economic migrants as a solution instead of a problem, in direct contrast to SAP's theory. The second factor was a direct threat to SAP's labour immigration policy. This leads to my second question, how did SAP respond to this pressure?The answers to these questions are achieved by using discourse analysis by applying a problem oriented theory on empirical material, constituting propositions, articles in mass media and parliamentary debates.
Den goda viljan. En studie av jämställdhetsarbetet vid Örebro universitet
In this essay, we attempt to study and analyze the work towards equality between men and women at the university of Örebro, Sweden. By using discourse analysis we have the ambition to test organizational theory with a gender perspective as the explanatory model for the schools successful work. We also have the ambition to develop our theory and ad an organizational theme focusing on actors..
Dömd för brott? Sambandet mellan intagnas implicita och explicita attityder till brott och kriminell belastningsgrad
According to statistics two thirds of Swedish criminals relapse into crimes within three years (Brå, 2007). Researchers suggest a relationship between attitudes toward crime and delinquent behaviour (Andrews & Bonta, 2003), but whether these attitudes are implicit or explicit remains unclear. Therefore, the aim of this study was to measure both constructs. Using SC-IAT (Karpinski & Steinman, 2006) and constructs from the Theory of planned behavior (Ajzen, 1985), criminals (N = 51) in three different prisons in southern Sweden were tested. Analysis yielded mixed results.
Kombinerad bekämpning i strid i bebyggelse
Even though battles have been fought in built-up areas for a long time, there have not been any specific theories connected to it. As the world becomes increasingly urbanized, the problem of not having any complete theories with which to analyze military operations in urban terrain becomes bigger. This essay aims to contribute to the field of military theory by investigating if Robert Leonhard?s theory of combined arms can be used in analyzing such operations and to be able to explaining the outcome of them. The main question posed in this essay is; to what extent can Leonhard?s theory explain the outcome of military operations in urban terrain? The method used to answer this question is a comparative method formed as a case study of two military operations in urban terrain, Operation Vigilant Resolve and Operation Phantom Fury, which both took place in Fallujah during the Iraq war 2004. The intention is to test Leonhard?s theory in both cases by assigning the theory several indicators, which are tested in each case. The result shows that the indicators appeared almost equally in both cases, even though one of the operations was said to be a success and the other a failure.
Brasilien - ett modernt men religiöst land : En fallstudie av Brasilien utifrån Pippa Norris och Ronald Ingleharts teori om sekularisering och religiositet
The aim of this study is to examine the religious landscape of Brazil, and based on the theory of secularization by Pippa Norris and Ronald Inglehart to explain why Brazilians are religious and not secular. The study is a secondary analysis that uses existing statistics to examine different units of analysis of Brazil?s religious landscape, economics and equality, etc. Based on their theory I find that Brazil is still religious due to the lack of security in the country. Brazil is insecure in terms of measures of socioeconomic equality, stable politics without corruption, and physical safety of the citizens in Brazil.
Revisionsbyråers signalvärde
Den 1 januari 1999 bildade elva länder (Belgien, Finland, Frankrike, Italien, Irland, Luxemburg, Nederländerna, Portugal, Spanien, Tyskland och Österrike) en europeisk valutaunion, det som också kallas euroområdet. Grekland anslöt sig, som en tolfte och ny deltagare, i januari 2001. Även om Sverige, Danmark och Storbritannien inte deltar från start har det varit klart att EMU kommer få konsekvenser för olika sektorer.Frågorna som behandlats i detta arbete är följande:Har EMU haft en effekt på de finansiella marknaderna i de länder som är med i valutaunionen?Har Sveriges, Storbritanniens och Danmarks finansiella marknader förändrats på samma sätt som i de länder som är med i EMU, fast dessa länder står utanför?Syftet med detta arbete är att analysera de finansiella marknaderna, genom beräkningar av vissa kända finansiella variabler, i de länder som deltar i valutaunionen och tre länder som står utanför (Sverige, Danmark och Storbritannien). Detta för att se om de finansiella marknaderna har påverkats av EMU och hur de har påverkats i och med inträdet.De variabler som behandlats är; ?-värdet, för att se om länderna går mot en gemensam marknadsrisk.
"Att stå på en hundsläde är ingen motion.": Hur motiveras polarhundsägare till fysisk aktivitet?
Tidigare forskning har visat att hundägare är mer fysiskt aktiva än de som inte äger hund. Deras motivation att vara mer fysiskt aktiv bygger på den sociala interaktionen med hund eller träningskompisar som hundträning/rastning medför. Med hjälp av Self-Determination Theory (SDT) undersöktes vad som motiverar just hundspannsförare att träna själv och hunden. Åtta personer som ägde hund och körde hundspann intervjuades. Frågorna kretsade kring tiden före och efter det att de ägde hund.
