Serban E VladSerban E Vlad was born in 1959 in Oradea, Romania and he works at present as analyst-programmer. He is a member of ROMAI and GAMM, the Romanian and the German societies of industrial and applied mathematics. He is the author of more than fifty papersand a chapter in a book. His research monograph Asynchronous Systems Theory' was published in several editions. His main fields of interest are binary valued analysis and asynchronous systems theory. In binary valued analysis, he defined for the real argument, binary functions the notions of integral and derivative. He studied also the periodicity of the real argument and discrete argument binary functions. In systems theory, he was concerned with modeling the asynchronous circuits from electronics. He defined the concept of delay and he wrote differential equations that model the ideal latches and other circuits. He introduced the regular asynchronous systems that, by some analogy with the (real, usual) dynamical systems, are generated by Boolean functions which iterate their coordinates independently on each other.
