For simplicity, we adopt the following convention: x, x1, x2, y, y1, y2, z, z1, z2, X, X1, X2 are sets, E is a non empty set, e is an element of E, u, v, v1, v2, w, w1, w2 are elements of Eω, F , F1, F2 are subsets of Eω, and k, l are natural numbers. Next we state a number of propositions: (1) For every finite sequence p such that k ∈ dom p holds (〈x〉 a p)(k+ 1) = p(k). (2) For every finite se...

This paper introduces a graphical notation called algebraic state transition diagrams (ASTD), which allows for the combination of state transition diagrams using classical process algebra operators like sequence, iteration, parallel composition, quantified choice and quantified synchronization. It is inspired from automata, statecharts and process algebras. Hence, it combines the strength of al...

In the autumn of 1978, Neil Jones and Steve Muchnick, working at the University of Kansas, were studying compiler synthesis from Scott-Strachey denotational-semantics definitions; I was Neil’s student. Neil read intently John Reynolds’s 1972 paper, Definitional Interpreters for Higher-Order Programming Languages [14], and applied Reynolds’s continuation-passing and defunctionalization transform...

it seems that resolution of internal conflict is studied less than the international one. current literature in this regard is not focused on theoretical aspects of conflict resolution, particularly, on conditions and necessaries of resolving these kinds of conflicts. nevertheless, in political science literature it is possible to find some texts that implicitly or explicitly are related to thi...

Understanding how enzymes catalyze specific reactions has yielded important insights into biology, provided the necessary context for the design of novel catalysts, and has facilitated the development of enzyme inhibitors for therapeutic purposes. The contributions of Professor W. Wallace Cleland helped to forge the modern framework for steady state enzyme kinetics, and together with his collea...
