When 60 years ago Shannon established “A Mathematical Theory of Communication” nobody could know the consequences for science and technology in the second half of the century. Shannon published his article in two parts in the July and October 1948 editions of the Bell System Technical Journal. However, it is very probable that this article wouldn’t have become famous without the help of Weaver,...

Distributed knowledge management systems (DKMS) have been suggested to meet the requirements of today’s knowledge management. Peer-to-peer systems offer technical foundations for such distributed systems. To estimate the value of P2P-based knowledge management evaluation criteria that measure the performance of such DKMS are required. We suggest a concise framework for evaluation of such system...

Actor-network theory, which is considered as a development of socio-technical structuralism school, observes reservation and stability of networks containing personal and impersonal components such as individuals, organizations, communication software and hardware, and infrastructural standards by examination of socio-technical dimensions concurrently.The goal of this research is studying the i...

the effects of agricultural information on the technical knowledge of the greenhouse owners in south khorasan province are dealt with in this study. research a descriptive-correlational methodology was ployed, and in terms of time, it was limited to the activities of the elements of knowledge and agricultural information as obtained from greenhouses during 2009. the study population consisted o...

Wearable computing is getting increasingly integrated in our every day life and the evolution of our community continues. In addition to the IEEE International Symposium on Wearable Computers, TC WIS co-sponsors the IEEE and ACM International Symposium on Mixed and Augmented Reality (ISMAR) and a few other conferences and workshops. The TC helped initiate the IEEE Computer Society’s Pervasive C...

Cognitive informatics (CI) studies the natural intelligence and internal information processing mechanisms of the brain, as well as the processes involved in perception and cognition. CI provides a coherent set of fundamental theories, and contemporary mathematics, which form the foundation for most information and knowledge-based science and engineering disciplines such as computer science, co...

Daily operation of structures and plants requires to manage and integrate large amounts of technical information. Existing approaches span from “no integration” to “strong integration” based on a common data base or product model. We propose concepts and technology to develop types of information systems in the middle. We call them “Weak Information Systems”. The basic concept is to add to the ...
