Syntetiska Instrument
This thesis aims to investigate SAAB AB´s possibilities to use synthetic instruments in their test systems. The reason for this is reducing costs and the risk of obsolescence which is common when test systems operate for several decades.The market around synthetic instruments has been explored in the search for suitable hardware and software. Software has been developed in LabVIEW and synthetic instruments have been created with the help of IVI-drivers. The hardware consisted of PXI-instruments (Waveform generator and Digitizer), connected to a computer using a fiber optic link and PXI-chassi. The created instruments was then compared to common instruments used today, and the comparison turned out well.
Miljöhänsyn inom EU:s sektorspolitik - integrering genom "nya" policyinstrument?
To integrate environmental concerns into non-environmental policy making has become an important policy objective within the European Union. This essay investigates policy instruments in use to achieve environmental policy integration in the EU's transport sector respectively fisheries sector. The point of departure is a theoretical discussion about governance and the use of different policy instruments for environmental management at the EU-level. The focal point is the argumentation that regulatory policy instruments alone cannot achieve environmental policy integration satisfactory. By using Jordan et al's classification of so called "new" environmental policy instruments (market-based instruments, voluntary agreements and ecolabels) as complements to regulatory measures, the essay investigates whether the first-mentioned are used within the two sectors.
Orala hälsorelaterade livskvalitetsinstrument som har använts på äldre individer ? en litteraturstudie
Aim: Through the review of scientific articles, this study aimed to identify which oral health-related quality of life instruments that have been used in studies to measure the oral health-related quality of life in older individuals and the application of such instruments.Method: The study is based on a systematic literature review, where 14 articles have been chosen and evaluated against a checklist. Result: The oral health-related quality of life instruments that have been used on individuals, 65 years and older, are OHIP-49, OHIP-14, OHIP-20 or OHIP-EDENT, GOHAI and OIDP. The instruments are used to examine factors associated with the oral health-related quality of life. Significant associations have been identified, among other things, between the number of teeth in static occlusion, dry mouth and the quality of the dentures, and oral health-related quality of life. Social and cultural associations have also been revealed.Conclusions: Today there exist several well functioning instruments that are used for research purposes.
Toner från förhistorien : En studie om förhistoriska musikinstrument och deras olika betydelser i det fornnordiska samhället
This is a study of Prehistoric musical instruments from Scandinavia and the different meanings they could have had in the Prehistoric society. I have described the different types of possible music instruments and the different categories that they belong to. I have also written about their different functions that could have been for example ritual artefacts, shamanic tools or useful instruments in hunting. Two case studies are also presented in the essay, the Falköpingsflute and the Balkåkradrum..

Programmering av styrutrustning för vridbord vid radarmätplats
Vid kalibrering av en radars antenn placeras radarn på ett vridbord som kan rikta in den mot en mast. På masten sitter ett kors som används som riktpunkt. Huvuduppgiften i examensarbetet var att skriva ett program i National Instruments programmeringsmiljö LabVIEW som kan ställa in vridbordet med en noggrannhet på 0,1 milliradianer. Programmet ska kunna användas som ett DLL (Dynamic-link library) i LabWindows/CVI där ett antal olika funktioner ska kunna anropas för styrning av vridbordet. Eftersom nästan all maskinvara är från National Instruments blev programmet väldigt lätt att skriva.
Musikinstrument i förskolan : En studie av förskollärares uppfattningar om användning av musikinstrument i förskolan bland barn i åldrarna 3 till 5 år
AbstractThis study was meant to cast a light on the use of music-instruments that exists in preschool environments today. Furthermore the purpose was to find out if instruments first and foremost, actually did exist, and what thoughts had been put behind that decision. The focus was directed towards the preschool teachers and their attitudes towards music instruments among preschool children, at the ages 3 to 5 years. The purpose of the study was to understand how preschool teachers thought of activities where music instruments where used. The study was made from interviews with six different preschool teachers from different preschools.
Utveckling av inbyggda system med grafisk programmering
The increase of complexity in embedded programming is forcing the development of higher level programminglanguages. These languages not only consist of traditional text based programming but also with graphical programminglanguages such as the programming language G from LabVIEW which is developed by National Instruments and havebeen around since the mid eighties. However since 2004 this language has also been able to program embeddedhardware, using the modules LabVIEW SDK and LabVIEW for ARM. This thesis shows how LabVIEW for ARM converts itsgraphical language G to C and then how C is flashed into the microprocessor. The thesis also takes up the pros and consof using G for embedded development.
Diplomati med klyvbar kärna - en kvalitativ studie av den ryska diplomatins grundval
AbstractThe purpose of this thesis is to analyse the basis of Russian diplomacy, and by doing that develop the analytical instruments available, in order to improve the comprehension between the parties in negotiations. Descriptions of the national characteristics of Soviet and Russian diplomacy are made by an analysis of memoairs and other examinations of their negotiating behaviour. To ensure the result of the characteristics two case studies of the non-nuclear proliferation negotiations are made, followed by a comparation between the Soviet and Russian diplomacy. From these results, I analyse the groundworks of russian diplomacy, using three theories about how ideology, national identity and prevailing self-image can affect the national negotiating behaviour. The results show that there have been changes in only some parts of the negotiating behaviour and that there is a need for all three theories to explain different parts of the complex system of Russian diplomacy which is based on the plurality of culture, ideology, language, ideology and history..

Validering av smärtformulär för katt
The objective of this study was to assess validity and reliability for five different owner-completed instruments evaluated to assess chronic musculoskeletal pain in cats. All of the instruments were questionnaires, three asking about behavioral changes, one about the degree of pain and one about quality of life. One of the instruments was written originally in Swedish, the other four instruments were translated into Swedish before use.
Data available were records from 57 cats with no signs of pain and 11 cats with different pain-related diagnoses. The diagnoses were ensured by clinical examination including palpation and manipulation of joints, gait testing on a force-plate and X-ray scans. Instrument 1 was completed by 57 pain-free and 11 pain-affected cats.
Tonala skillnader mellan ett tryckande stall och ett limmat stall. : -hos en bouzouki
SummaryI have a great interest in bouzoukis and since I, during my education in guitar making, mainly have focused on building bouzoukis and other traditional folk instruments, I have chosen the bouzouki as the object of my degree project.In connection to the making of these instruments, I started to consider the construction of the bouzouki and why the bouzouki has such a characteristic sound.One of my theories is based on the fact that most bouzoukis are made with floating bridges instead of glued pinbridges. Do these types of bridges differ from each other tonally and if so, how much and in what way?To receive answers to my questions, I have built two identical bouzoukis with different types of bridges, one with a glued pinbridge and one with a floating bridge. I have been very precise in the making of these instruments, giving them the exact same dimensions and using material from the same piece of wood. This to make sure that the instruments should be as exactly alike as possible.After finishing the making of the bouzoukis, I arranged for a sound test where I let musicians play and listen to the instruments.
Design och implementation av ett stamningsförebyggande system med DSP teknik
Uppgiften består i att konstruera och designa en DSP lösning för att förebygga stamning. Genom att en signal tas in på en mikrofon och bearbetas i en DSP därefter skickas ut på en hörlur.Signalen som behandlas i DSP:n ska frekvenshöjas och fördröjas.Pitch och fördröjning ska kunna justeras m.h.a. en omkopplare.Till hjälp fanns utvecklingskortet eZdspF2808 från Texas Instruments och en in/utgångsförstärkare.Tidigare erfarenheter av DSP från Texas Instruments saknades. Att lära känna utvecklingskortet var därför en del av arbetet. Det bestod mest i att läsa användarguider från Texas Instruments hemsida.Utvecklingskortet saknar en DA-omvandlare, en sådan konstruerades..
