There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

The problem with passive farmers has arised as an effect of the European Union´s common agricultural policy (CAP) and the decouplement from production-based payments. Payments to passive farmers contradict the purpose of the single payment scheme and constitute a great cost for the EU. The new contractual period after 2013 has given rise to discussions on the direction of the CAP with a purpose of increasing the efficiency of the single payment scheme, and reducing passive farming. The aim of the study is to increase the knowledge about a few factors? influence on passive farmers? attitudes towards land use and the CAP.

Application Lifecycle Management (ALM) is a genre of computerized systems which allows system development corporations to efficiently and more easily manage, maintain and handle the applications lifecycle. These ALM systems have a wide variety of tools which can be integrated to enable and support collaborative work, while they act at the core of the organisation. Todays ALM systems support flexible system development methods throughout the entire development process. This paper focuses on a case-study of a Swedish business- and technology corporation and their use of two ALM systems with an aim to unravel the differences between these systems and their functionality to serve as a basis for decision making regarding their utilization of best practice with their ALM-Systems. Meanwhile we studied their approach to ALM systems to see if they were using them according to the initial idea of ALM systems.

I detta arbete har vi studerat tjänsten SMS-betalning. Vi har fokuserat på att utvärdera och beskriva tjänstens användningsområde samt dess styrkor och svagheter. Utifrån företaget Mobill, vars affärsidé är att utveckla en betalningstjänst via SMS har vi fått en bild av hur ett företag kan satsa på denna teknik. I en studie med konsumenterna har vi visat den generella bilden av inställningen till betalningstjänsten, detta för att vidare kunna utvärdera betalningssystemet. Dessa studier har båda en kvalitativ karaktär.

Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

In almost every workplace today IT-systems have strong and significant roll in theeveryday work. It is therefore important that the systems have a good functionalityand that they work as an aid for the users. This thesis aims to study the systems atthe company Telge Nät and to analyse them from a usability perspective. By using thisperspective it has been obvious how difficult it is to make improvements on usability,once the system is in place. Even other larger improvements of the systems aredifficult to make at this stage and this is something that the users are aware of.

The enormous expansion of knowledge society has lead to a path away from the industrial enterprises toward the more knowledge-based entrepreneurship companies. This development has also meant that intellectual capital now can be seen as the core of the new business structure. However the growth has not been reflected in either the legal or the economic regulations in relation to what could have been expected, which means that there is thus a gap between de lege lata and de lege ferenda. This can specifically been seen regarding the prohibition of adding property other than cash applied in payment for shares or regarding issue of new shares when it comes to work and services. The prohibition may therefore be considered to stand against the knowledge companies? advancement.

This essay is about testing the validity of an article written by Jonas Löwgren, called The use qualities of digital design. The study we have executed is about testing the featured qualities of digital design in the article on two search systems located in the library of Stockholm University and Södertörn University respectively to see how they are able to be applied on search systems. To acquire the information for the study, we handed out a written inquire among users of those systems. The result of this quantitative study shows us that many that five of Löwgrens qualities is likely to be present on the systems. Our conclusion is that five of these are appliable on search systems.

Banking systems in India is quite popular and it needs some more changes to reach all the customers. Lack of the service is main problem in Indian baking system. If the common person wants to open the account, it take?s little bit high cost and banks are not near the people location. Due to the Lack of service, people do not want to be a customer of the bank.

I ett kortbetalningssystem såsom Visa International Service Association (Visa) finns det fem stycken tongivande parter: kortinlösaren; kortutgivaren; kortinnehavaren; säljföretaget och Payment Service Provider (PSP). Ett säljföretag som låter sina kunder betala för varor och tjänster på sin webbplats skickar kundernas kortnummer krypterat till en PSP som vidarebefodrar dessa till VisaNet som är dataknutpunkten i Visa. VisaNet söker med hjälp utav kortnumret upp den bank som har utgivit kortet och efterfrågar samma bank om en transaktion får ske från kortet. VisaNet får ett svar som vidarebefordras vidare tillbaka till säljföretaget som sedermera även får sina pengar överförda till sitt konto från kundens konto.Uppdragsgivaren till detta examensarbete skall utveckla ett helt eget system och bli sin egen PSP utifall uppdragsgivaren beräknar att mer än 1,3 miljoner stycken kortbetalningar kommer att ske genom uppdragsgivarens kortbetalningssystem per år. När detta examensarbete utfördes uppskattades antalet kortbetalningar per år inte till denna siffra och rapportförfattaren utvecklade därför ett korbetalningssystem med hjälp utav en befintlig PSP.Kortbetalningssystemets kärna är ett API som andra systemutvecklare hos uppdragsgivaren kan anropa.

Product sharing systems is recently starting to become a more common phenomenon. Carpools exist in more than 40 Swedish towns and both Stockholm and Gothenburg have established bicycle sharing systems. Other products for which sharing systems have been established throughout Sweden are clothing and tools. From the point of view of the consumer, product sharing systems is a form of consumption which can be placed somewhere in between renting and privately owning a product, where the consumers usually pay a membership fee or a monthly fee to have access to the products whenever they need them. The concept is relatively new, and there are many products for which product sharing systems do not exist.

1st of may 2003, a new energy system based on electricity certificates, was initiated in Sweden. The purpose with this system, is to stimulate an enlargement of energy production from renewable sources. The electricity system, ist built on that the producers of energy from renewable sources confer a electricity certificate from the government for every produced MW energy from renewable sources. The electricity certificate is supposed to be turned over and with that generate reciepts to the producers. Furthermore there is an obligation for the energyusers und energysuppliers, that means that the users and the suppliers every year the 1st of april got to have electricity certificates in proportion to their energy consumption during previous year.

Syfte: Identifiera de olika betalningsmedlen för att finna samband mellan upplevelserna av deras säkerhet, enkelhet och hur dessa aspekter påverkar valet av betalningsmedel.Metod: Kvantitativ metodTeori: Litteratur, vetenskapliga artiklar och empiriska rapporterEmpiri: En enkätundersökning gjordes för datainsamlingSlutsats: Undersökningen bekräftar att både upplevelsen av säkerhet och enkelhet påverkar konsumenterna i valet av betalningsmedel. Vår undersökning visar att enkelhet ör den vanli-gaste och viktigaste orsaken för en konsument i valet av betalningsmedel. Undersökningen visar även att i olika ålderskategorier skiljer sig användandet av de olika betalningsmedlen åt och den visar även på olika värderingsgrunder vad gäller säkerhet och enkelhet mellan ålders-kategorierna för valet av betalningsmedel..

This study aims to examine the effect management control systems have on which goals health centers prioritize. The management control systems of one privately owned and one publicly owned health center have been studied through a qualitative case study. Robert Simons (1995) framework with four levers of control (diagnostic control systems, interactive control systems, belief systems and boundary systems) has been used to structure the study. For both health centers we found a conflict of interest mainly between the diagnostic control system and the beliefs system, where the diagnostic control system is biased towards quantitative goals and the beliefs system is mainly biased towards qualitative goals. However, despite the unbalanced levers of control the studied health centers have been able to reach a well functioning compromise between quantitative and qualitative goals..
