Biosensor-based Methods for Detection of Microcystins as Early Warning Systems

Popular Abstract in English Global invasion of our precious watercourses by cyanobacteria poses great threat to human- and animal health by deteriorating water systems. In fact, this problem is not likely to be solved in the near future as cyanobacteria are associated with pollution of waterways. Consequently, water sources are subject to contamination by natural toxins produced by abundant growthCyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. The high toxicity and in

Knowledge-Based Control Systems: Aspects on the Unification of Conventional Control Systems and Knowledge-Based Systems

Different aspects of the integration of conventional control system and knowledge-based systems are discussed. Special requirements such as multiple forms of knowledge representation, support for model-based reasoning, and real-time operation are discussed. Three different forms of integration are described: interfaced systems, embedded systems, and totally integrated systems.

Substrate Control in Fed-Batch Cultivations Using a Model-Based Modification of a PI-Controller

A fedbatch process shows exponential growth under ideal conditions. To obtain good substrate concentration control it is necessary that the regulator can track an exponentially growing feed demand, and standard PI-control has to be supplemented with an estimated basic dosage to get reasonable control. However, an exponentially growing concentration error is impossible to avoid. An I-term could be

A Helping Hand: Industrial Robotics, Knowledge and User-Oriented Services

In this paper we discuss AI in industrial robotics. In automatic control, computer vision and optimization, ma- chine learning and data mining algorithms are widely used. However, cognition enabling mechanisms, such as high-level logic and symbolic reasoning, are still limited. This is not due to the lack of available algorithms, rather the bottleneck is knowledge representation, acquisition and t
