Optimal bredbandig vågform framtagen genom generaliserad osäkerhetsfunktion

The waveform of a radar signal affects the resolution in velocity and distance. The ambiguity function is used as an aid for analysing narrow band radar signals simultaneously in time and frequency. An analysing tool for wide band radar signals is missing.This thesis describes a generalised ambiguity function to be utilised for study of wide band signals. Waveforms are further synthesised with help of the developed analysing tool. The aim is to start with a certain ambiguity function and find a waveform that reproduces the same ambiguity function.Mathematical formulas are presented and implemented in Matlab to produce the wide band ambiguity function.

Framgångsfaktorer i ett fallförebyggande arbete inom hemtjänsten

In 2005 over 48 000 senior citizens fell so badly that the needed medical care and almost 1200 of them died. This makes falls in the elderly one of our biggest public health problems. Research in this area is extensive and although we know what causes a fall and how we in theory should work to prevent their occurrence, this is a problem that is increasing. There seems to be a gap between research and practice, and research into why this gap occurs is very narrow. The purpose of this study was to identify success factors with fall prevention from a staff- perspective.

Fred och säkerhet? : En studie om det Svenska Försvaret utifrån tre perspektiv, Bonsdorff, Andrén och Clausewitz

Following an increase in hostile foreign activity. The discussion regarding Sweden?s defense force´s ability to perform its task has come to a new heading. With the end of the cold war as a major revolution in matters of international security, a major overhaul has taken place to transform the static total defense plan of the nation to a less rigid operational system.Following an analysis of the budgets total amount from the governments of 2002 until 2015 it is clear that while the amount of resources has never directly been lowered, it has shrunk in relation to the countries total GDP. The possible futures for the defense of Sweden bring three possibilities forward in correlation three unique perspectives on military and political policy.Out of the three possibilities the focus on military strength as a political resource seems to be garnering the most support with the latest incursions made my foreign submersibles and the ever growing presence of 5th generation of warfare.

Att ösa ur ett hav : Om kunskapssyn och urvalsprocesser hos gymnasielärare i Samhällskunskap A

Teachers in social sciences have a broad subject field to base their education on. This term paper examines, thru interviews, which factors that have an influence on the subjects contents in the A course of Social Sciences at Swedish high schools. Having interviewed four active teachers at three different schools, it shows that control documents like subject- and national curricula have little to say about what kind of subject that should been taught. Teachers seem rather to rely on local collegiate consensus, the textbook, locally prepared control documents, and adjusting to program directions while choosing material. In the final discussion the risk of structuring the subject around the text book is being investigated, along the fact that new locally control documents need to be written even for basic planning structures.

Analys och förbättringsförslag för riktkopplardesign

Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations.The most important parts of directional coupler theory are presented. It is necessary to study this theory to understand how the coupler works and how it should be designed to get good performance.Optimal directional coupler termination component values to get high directivity and broad directivity bandwidth have been investigated.The trim screws trim ranges have been studied.A simple analysis of serial production performance when termination component tolerances are taken into consideration has been done.The resistance components reactive (inductive/capacitive) characteristics at 2.14 GHz have been analyzed.The directivity performance limitations of the directional coupler, when Ericsson?s band pass filter is connected, are investigated.Design changes leading to better performance are proposed.

Från varuperspektiv till servicelogik : ett arbete om rollförändring och öppenhet på webben

This study focuses on the transfer between a product-oriented to a service-oriented perspective regarding marketing activities in companies due to the development of information technology. It illustrates how this very transfer has been, and can be, contemplated through the eyes of organizations working with marketing in a digital world on a daily basis. Technology has turned several industries - their price-setting, communication channels and supplying possiblities - upside-down. This turnpoint brings out a new way of observing and working with marketing. Therefore, we find it interesting to gain a better understanding of how actors within industries where the turnpoint is a fact observes marketing, and how this service perspective can be seen in their various organizations and daily.
