Säkerhet och integritet i närfältskommunikation
Context. In today?s society we use smart cards in many areas, NFC is a smart card technology that allows contactless interaction between a reader and the tag, the tag is often in the form of a card. NFC can be used for various payment methods or as access card to a building which makes life easier. In previous studies, the technique has proven to be weak to attacks using an NFC reader connected to a computer.
Estimering av GPS pålitlighet och GPS/INS fusion
The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning. An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.
Slaget om Malta analyserat i ett militärteoretiskt perspektiv : Wardens och Boyds luftmaktsteorier tillämpade på ett empiriskt exempel
Slaget om Malta, under andra världskriget, hade en avgörande roll vad gäller kriget i Medelhavet. Maltas strategiska läge gjorde att det var en åtråvärd ö för axelmakterna och britterna kämpade för att försvara sin position. I kampen om sjöherraväldet hade luftrummet stor betydelse och hur flygstridskrafterna användes var direkt avgörande. John A. Warden III och John Boyd är båda framstående luftmaktsteoretiker och deras teorier har fått stort genomslag, framförallt i västvärlden.
Energieffektiv högtalare med trådlös kommunikation
Music today is a big part of a person's everyday life and can influence emotions as wellas initiative and motivation. This effect together with development in technology hasled to that music today is accessible and can be played from a large amount of differentkinds of products. This in turn has meant that the demand for smaller audio playbackdevices is greater than ever.The goal of this project is to develop a concept for energy-efficient speakers withwireless communication that has the ability to obtain and play high quality music. Thespeakers will use the latest available technology and at the same time, using digitalsignal processing, have a low environmental impact through high energy efficiencyand low power consumption. Parallel to this work a pilot study will be conducted tosee trends in listener preference of sound.The result achieves the goals pledged while power consumption in sleep mode is solow that they meet the demands of tomorrow.
Framtagning av analysmetodik för uppslutning av kemiska produkter
The purpose of this thesis was to develop and optimize a method of analysis for combustion of organic chemical products, followed by an ion chromatographic quantitative analysis. This was to be achieved with the decomposition equipment IKA AOD 1. The aim was to receive a precise and repeatable method that would be able to be applied to the process of qualification and technical marking of chemical products at the company, OKG AB in Oskarshamn. A complete instruction for the decomposition equipment and the method of analysis was written. A number of parameters were chosen from the general method of the combustion equipment, which then was tested parallel with a simultaneous development of an appropriate ion chromatographic method.
Klädföretagens CSR arbete : En dokumentstudie
Those companies that have taken a stand in corporate social responsibility and work with these issues often experience difficulties orienting themselves in these areas. There is a picture of how companies want to be in their CSR commitment on corporate websites and a different reality which is reflected in the media. These different images are not in harmony with each other.The purpose of this study is to revise the CSR work of Sweden?s largest clothing companies.To answer the problem of this study a qualitative method has been used. The choice to explore a few clothing companies resulted in a multi-case study.
Immunohistochemical evaluation of antibodies for staining of mouse spinal cord and mouse neuronal cells
The United Nations has, during many years, developed a model for a globally harmonized system for classification and labeling of chemicals, with the aim of it becoming a global standard. This system is implemented in the European Union through the CLP-regulation and is now working parallel to the existing directives until 1st of June 2015, when all the new classifications of substances and mixtures must be completed. The aim of this project was to adjust the laboratory to the new legislation, through inventory of stored chemicals, update the list of chemicals and perform self-classifications of mixtures. The work included handling of about 650 different chemicals with varying hazard classifications and search for information in corporate websites and chemical databases. This resulted in a new and complete list of chemicals stored and used in the laboratory and, in addition, an example of how to make a self classification of a mixture.
Laboratory adjustment to the new regulation on classification, labeling and packaging of substances and mixtures.

USA och FN- samarbete eller konflikt
AbstractUniversity of Växjö, School of Social SciencesCourse: PO 5363, Political Science 41-60Title: US and UN, cooperation or conflict?Author: Charlotta BjuvlingSupervisor: Lennart BergfeldtDate: Autumn 2007The international society changed a great deal after the end of the cold war. It gave the United Nations a new oppertunity to act after the deadlock during the war, and it gave the United States a new hegemone role in the world politics. The aim of this paper is to investigate wheter the United States foreign policy action have been accordence to a realistic way of thinking since the end of the cold war. I will do this with the help of my research questions:? Have the United States followed the guidelines of the United Nations in their foreign policy?? Are there signs that show of a change, either towards more or less cooperation between United Nations and the United States?To answer these questions I will use the theories realism and Hedley Bulls concepts of fairness and his ideas of an international system in his book ?An Anarchical Society?.
Radikala ändringar av marknadsförhållanden och strategiska förändringar
There is much literature covering strategic change under different circumstances but very little concerning how companies act strategically under sudden and radical changes to market conditions. Based on three different events (the terrorist attack in the USA September 11th 2001, the Tjernobyl accident April 26th 1986 and the Islamic revolution in Iran 1979) with such radical changes as a result we chose three companies that were affected (SAS, Asea Atom and Atlas Copco). The result of the events that were studied in this thesis is extremely unusual to their character. The events themselves were sudden and of a temporary nature but the results were long term changes of market conditions. Through personal interviews the authors have tried to establish how the companies have perceived the events and how the top management has strategically handled the situation.
Konsten att bibehålla en organisationskultur med anställda som kombinatörer
Organizational culture is a widely discussed topic. Today job mobility in society is increasing as well as part-time employment. This study aims at investigate how organizational culture is maintained in an organization where employees work as combiners of different work occupations. The study is a case study of the department of Art at Konstfack (The University College of Arts, Crafts and Design). The organization is unique in the respect to that the majority of the employees have part-time employments within Konstfack combined with their parallel own artistic occupations.
SAB-systemets utveckling 1985-1997
The aim of this Master's thesis is to compare the 6th and the 7th editions of the classification scheme of the Swedish classification system (SAB) to reveal which principles are used concerning the development of this system during the period 1985-1997. Guiding questions are: What kind of changes has been conducted? How do these changes relate to development of other general classification schemes and to theories concerning revision work? The results of the analysis show that possibilities to use synthesis have increased by an extension of use of geographic and chronological subdivisions. The classification scheme has also been easier to use by elimination of parallel subdivisions and regularization of the scheme. To maintain stability revision is performed on selected subclasses.
Direkt och indirekt metod inom manöverkrigsföring : Hur kan de appliceras på IT-krigsföringen?
Manöverkrigsföring är ett tillvägagångssätt för att undvika motståndarens starkare sida och angripa dess svaga, för att jämna ut styrkeförhållandena på slagfältet. B H Liddell Hart har sammanfattat detta i sin teori om den indirekta och direkta anfallet. I detta arbete har författaren prövat denna teori på IT-krigsföringen. Genom en kvalitativ textanalys har en teoriprövande undersökning genomförts med syftet att granska den svenska militärstrategiska doktrinen. Undersökningen har använt sig av tre olika analysenheter att pröva teorin på.
Kartläggning och utvärdering av informationssäkerhet i en kommun
Informationssäkerhet har idag en viktig roll inom organisationer. Det finns undersökningar som visar på att attacker ökar för varje år. För säkerhetskritiska organisationer som kommuner är det därför viktigt att man har uppdaterad säkerhetsteknik, då man lätt kan falla efter i det snabbt utvecklande ämnet informationsteknik. Uppgiften som gavs av Nexus AB var att kartlägga och utvärdera en kommuns informationssäkerhet. De ville få reda på hur det egentligen låg till med informationssäkerheten i en Stockholmskommun.
Inverkan av stora mängder halm som underlag i grisningsboxen på den nyfödda smågrisens temperaturreglering :
The aim of the present study was to evaluate the effects of large amounts of straw
in the farrowing pen on thermal regulation of the newborn piglet in different
weight classes. 20 sows were given 15 kg of straw in the farrowing pen
2 days prior to until 7 days after parturition. A control group of 18 sows
had no straw in the pen. 6 litters from each treatment were observed.
Measurements of piglet body temperature were made at 0h, 2h, 4h, 8h and 24h
after parturition. At ?8h? the body temperature of the piglets in the Straw group
were significantly higher (P=0,0149) than the piglets in the Control group.
