Herwart Opitz,Ernst Ulrich Dregger,Günther Geiger,Ernst Rehling a new mathematical approach to imperfect knowledge..The problem of imperfect knowledge has been tackled for a long time by philosophers, logicians and mathematicians. Recently it became also a crucial issue for computer scientists, particularly in the area of artificial intelligence. There are many

A key issue for substation data analysis is the adequacy of our knowledge available to describe certain concepts of power system states. It may happen sometimes that these concepts cannot be classified crisply based on the data/information col

Herwart Opitz,Ernst Ulrich Dregger,Günther Geiger,Ernst Rehlingudy is based on the conceptual framework of information quanta [4,5], where each system is defined as a relational structure and all approximation operators are defined in terms of Galois connections. We start our investigation with Scott systems, that is sets equipped with Scott entailment relation
