Ordering and Convex Polyominoesies of special families of discrete sets (corresponding to {0,1}-matrices) with respect to this partial order. In particular we consider the families of polyominoes and convex polyominoes and the family, recently introduced by the authors, of L-convex polyominoes..In the first part of the paper we s

Sequential P Systems with Unit Rules and Energy Assigned to Membranesin the area of membrane systems) and, moreover, every membrane carries an energy value that can be changed during a computation by objects passing through the membrane. For the application of rules leading from one configuration of the system to the succeeding configuration we consider a sequential

Register Complexity of LOOP -, WHILE -, and GOTO -Programsunctions from the non-negative integers to the non-negative integers. It turns out that the hierarchy of .-computable (.-, and .-computable, respectively) functions .:?. →?. (partial functions ., respectively) that is induced by the number of registers collapses to a fixed level. In all three cases
