MGS is an experimental programming language dedicated to the modeling and the simulation of a special kind of discrete dy- namical systems. Dynamical systems with a dynamical structure (or (DS)(2)) arise when the state space is not fixed a priori but is jointly computed with the current state during the simulation. In this case the evolution function is often given through local rules that driv...

Various interrelated issues that effect the reliability and efficiency of Newton-like methods for chemical process optimization are studied. An algorithm for solving large, sparse quadratic programming (QP) problems that is based on an active set strategy and a symmetric, indefinite factorization is presented. The QP algorithm is fast and reliable. A simple asymmetric trust region method is pro...

In this work, we predict a new physical phenomenon, induced fission-like process and chain reaction of hadronic molecular states. As state, if by $D$ meson, the $X(3872)$ can split into $D\bar{D}$ final state which is forbidden due to spin-parity conservation. The breeding meson reaction, such as $D^0X(3872)\to D^0\bar{D}^0D^0$, makes matter possible. We estimate cross section two mesons. With ...

Drying represents one of the oldest unit operations employed in industrial processes. Drying is viewed as a process of simultaneous heat and mass transfer. Porous Clay-like material undergoes stresses due to non-uniform distribution of temperature and moisture induced by heat and mass transfer respectively. The aim of this work is to simulate the stresses induced by heat and mass transfer durin...

The first results, both positive and negative, recently obtained in the area of constructing stationary spinning solitons in flat Minkowski space in 3+1 dimensions are discussed.

By dimensional reduction of a massive supersymmetric B∧F theory, a manifestly N = 1 supersymmetric completion of a massive antisymmetric tensor gauge theory is constructed in (2+1) dimensions. In the N = 1−D = 3 superspace, a new topological term is used to give mass for the Kalb-Ramond field. We have introduced a massive gauge invariant model using the Stückelberg formalism and an abelian topo...
