The purpose of an information system is to manage data, information and knowledge connected with human activity. Information Systems in Collaborative Networks manage available data and describe conditions and information generated by data integration corresponding to the various stages of products and services in the network, and the actions taken by network staff in order …
In large-scale WSNs (wireless sensor networks), packets of a source node are often transmitted via multi-hop relays to reach their sink nodes. The hop-count, h, of a sink node is related to a particular hop-count originator (namely the source node) and it is defined as the least number of multi-hop relays required to send one…
Equipment disturbances and errors have become more serious as a consequence of the growth of the electronic circuit complexity. According to new technical legislation and also economic consequences, the electromagnetic compatibility (EMC) concept of all products must be strictly observed (Montrose & Nakauchi, 2004). It must start with the specification of the equipment performance and …
Fuzzy systems have been demonstrated their ability to solve different kinds of problems in classification, modeling control and in a considerable number of industry applications. It has been shown as a powerful methodology for dealing with imprecision and nonlinearity efficiently (Wang, 1994). However, one of the shortcomings of fuzzy logic is the lack of learning …
Automatic visual monitoring systems gain more significance as the enhancement of high speed processors that are able to execute the prolonged algorithm efficiently. Video surveillance monitoring systems are typically applied to study human behavior in a crowded situation. It is used to observe posture, movement, trajectories and the interaction between people. For this purpose CCD…
The body mass is one of highly important indicators of the development of the young cattle, therefore it is essential to follow it up. Only the animals with sufficient body frame and with well muscled top – quality body parts can be successfully fattened to high body mass. To obtain the highest precision in measuring…
Synthetic Aperture Radar (SAR) systems are all-weather, night and day, imaging systems. Automatic interpretation of information in SAR images is very difficult because SAR images are affected by a noise-like characteristic called speckle that arises from an imaging device and strongly data and makes automatic image interpretation very difficult. The speckle noise in SAR images can be …
Face Recognition by a robot or machine is one of the challenging research topics in the recent years. It has become an active research area which crosscuts several disciplines such as image processing, pattern recognition, computer vision, neural networks and robotics. For many applications, the performances of face recognition systems in controlled environments have achieved…
Internet environment and internet based tools enable numerous opportunities of establishing new enterprises even without any actual, physical office. Such enterprises are already functioning in many services, e.g. language, banking, trading, to full extent. This is also true in various engineering activities. Such an environment is also beneficial in case of multinational companies, since it …
HealthCare Product Design, and in particular the development of bio-electronic device for diagnosis and monitoring, is usually very complex because it concerns many different disciplines (eg. Medicine, Electronics, Computer Science, Product Design, etc.). Moreover Healthcare products are almost always used by many different actors, for example caregivers, physicians, patients and their relatives. They can be …
