Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

The purpose of the Sharing Economy is to exploit unused resources between people, as an alternative to buying new and owning themselves (Gansky, 2010). Gansky (2010) argues that a major reason why the Sharing Economy has grown in recent times is, besides from the recession and people?s increased environmental awareness, the urbanization which has made people move closer to each other and in to the big cities. This in addition to an increased use of GPS technology in smartphones enables people to be constantly connected to an ever-changing network. People now share and exchange services and products from each other.

The systems environments of today are often distributed and heterogeneous. These kind of systems have several advantages but also disadvantages. One problem is how to keep them secure.The security problems in these environments are mainly due to the communication between the connected computers. It is relatively easy to tap these communication channels from information. There is also a need for the possibility to secure these channels from modification of sent information and to be able to verify the sender and receiver of information in a secure manner.

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

The purpose of this study is from a teacher?s perspective to examine how schoolteachers experience the possibilities of learning from each other within their work team and to shed some light on how teachers believe that cooperation affects their ability to learn and improve on a daily basis. My research questions are: What is the general discussion among the teachers concerning daily capacity building from enhanced teamwork? How important is well-functioning cooperation between co-workers for learning and daily capacity building? What are the prerequisites for a well-functioning learning situation within the work team?The study is based on five qualitative interviews with teachers within the same school but from different teaching backgrounds based on what grade they teach, what subjects they teach, and they belong to different work teams within the school. The interviews are semi-structured.The results have been analysed from a perspective based on the theories of organisational pedagogy and learning organisations.The results implies that the work teams does not function as a forum for exchanging experiences and learning from each other.

The aim of this thesis is to mediate to the reader an image of Chinese classification systems and in what way the methods of classification have progressed during time. The tradition of classification in China is very old and dates back more than two thousand years, but it wasnt until the downfall of the dynastic era in the beginning of the 20th century, that Chinese libraries and methods of classification were modernized. This thesis also identifies the development of Chinese librarianship which is of old age since Chinese literature stretches three thousand years back. The main question is in what way the values of three different philosophies are reflected in five classification systems compiled between 1953-1975. The three philosophies are Daoism, Confucianism and Maoism/Mao Zedong Thought.
