ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler

In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.

En studie av zero knowledge-identifikationsprotokoll för smarta kort

Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

Varför har högerpopulismen uppnått framgång i Norden? : En komparativ studie av Sverigedemokraterna, Fremskrittspartiet och Danske Folkepartiet

The purpose of this study is to present populism as a political phenomenon and to impose focus on the rightwing populist parties that are active in Scandinavia. This essay begins with a presentation of the three rightwing political parties in Scandinavia.

BBIC i samverkan för barnets bästa

Purpose of this study is to investigate whether BBIC had an effect on the interaction between social services and schools. To find this out, a comparative study carried out between two municipalities in southern Sweden who has worked with the BBIC system different lengths of time. The empirical data is based on six qualitative interviews with heads of unit in social services, principals in secondary schools, and social workers who work with children- and youth investigations. The theoretical framework consists of Bronfenbrenners Ecology model, systems theory as organizational theory and the theory of autopoiesis, and Danermark model of collaboration. The results of the survey show that respondents do not find that their inter-organizational collaboration has been significantly affected by the implementation of BBIC, but that BBIC provides a good basis for collaboration due to the logic and structure of the system..

Budget som styrmedel ? ett effektivt verktyg eller ett onödigt ont?: En fallstudie av den ekonomiska styrningen inom Luftfartsverket

The aim of this Master?s thesis is to examine the function of the budget as a means of control within an organisation in the public sector. To accomplish this, a case study has been conducted on a certain business unit within Luftfartsverket responsible for providing Air Traffic Control services. The thesis is built on a framework of contemporary theories of budgeting and includes a brief discussion of the weaknesses usually associated with the traditional budget. The conclusion of the study is that the use of budget as a means of financial control within Luftfartsverket is not efficient enough at the moment.

Identitetsverifiering via tangentbordsstatistik

One important issue faced by companies is to secure their information and resources from intrusions. For accessing a resource almost every system uses the approach of assigning a unique username and a password to all legitimate users. This approach has a major drawback. If an intruder gets the above information then he can become a big threat for the company and its resources. To strengthen the computer security there are several biometric methods for identity verification which are based on the human body?s unique characteristics and behavior including fingerprints, face recognition, retina scan and signatures.

Utveckling av differentierade transportersättningar för rundvirskestransporter med lastbil

Approximately 60 million cubic meters of round wood are transported every year with trucks in Sweden and stand for 15 % of all truck transportation in the country. The big amount that is transported results in many haulage companies works in different parts of the country with different conditions to get a good flow on their transports. Today the transport pricing is very general and the payment consists of the unit round wood they are transporting and the distance of the transport. The purpose of this study were, from the freighter and the haulage company?s perspective, try to find ways to change the today applied transport pricing to more differentiated and compare them to historic payment of transportation.

Mätning av axiella magnetiska läckflöden i vattenkraftsgeneratorer

This thesis describes a method of measuring axial magnetic leakage flux in an operational hydropower generator. Axial magnetic leakage flux is the magnetic flux at the ends of a rotating generator, which goes through the stator parallel to the rotor axis. This flux can cause circulating currents in the stator iron, giving rise to losses, and can in the worst case overheat a generator, causing it to melt down. To measure the axial flux, and how it affects the generator temperature, a measurement system was constructed on behalf of Vattenfall. The system consists of search coil sensors and a signal-processing unit with amplifiers and active filtering.  To confirm the behaviour of the axial leakage flux and the functionality of the measurement system, a test installation was made.

Container Security Initiative - En diskursanalys utifrån teorier om det il/legala

Container Security Initiative was launched in 2002 by the US Customs and Border Patrol in order to secure the global flow of containers destined for USA. This thesis attempts to analyze Container Security Initiative in relation to a possible future scenario made by the weapons industry where the state's global traderoutes are being subject to militarization. A development which is partly based on the threat posed by global illegal trade. The latter is discussed and defined based on current research made by Carolyn Nordstrom, Moíses Naím and theories on the cosmopolitan perspective made by Ulrich Beck. Strategy documents concerning Container Security Initiative are then analyzed in terms of discourse to try to say something about what the program indicates.
