In this paper, a method based on Non-Dominated Sorting Genetic Algorithm (NSGA) has been presented for the Volt / Var control in power distribution systems with dispersed generation (DG). Genetic algorithm approach is used due to its broad applicability, ease of use and high accuracy. The proposed method is better suited for volt/var control problems. A multi-objective optimization problem has ...

A subset of vertices in a graph is called total dominating set if every vertex the adjacent to at least one this set. minimal it does not properly contain another In paper, we study graphs whose all sets have same size, referred as well-totally-dominated (WTD) graphs. We first show that WTD with bounded domination number can be recognized polynomial time. Then focus on two. case, characterize t...

Many engineering design problems must optimize multiple objectives. While many objectives are explicit and can be mathematically modeled, some goals are subjective and cannot be included in a mathematical model of the optimization problem. A set of alternative non-dominated fronts that represent multiple optima for problem solution can be identified to provide insight about the decision space a...

A graph is said to be well-edge-dominated if all its minimal edge dominating sets are minimum. It known that every G also equimatchable, meaning maximal matching in maximum. In this paper, we show a connected, triangle-free, nonbipartite, graph, then one of three graphs. We characterize the split graphs and Cartesian products. particular, connected product $$G\Box H$$ well-edge-dominated, where...

Aim We assessed the role of mowing machinery and endozoochory by migratory sheep as dispersal vectors in semi-natural grasslands comparing species compositions traits found to regional above-ground vegetation soil seed bank. Furthermore, we discuss how their interplay may affect conservation grasslands. Location Rhön Mountains, central Europe. Methods Plant material from mowers (n = 12 one date...

Pollination and seed dispersal determine the spatial pattern of gene flow in plant populations and, for those species relying on pollinators and frugivores as dispersal vectors, animal activity plays a key role in determining this spatial pattern. For these plant species, reported dispersal patterns are dominated by short-distance movements with a significant amount of immigration. However, the...

objective(s): first, 10-bromodecanoic acid was covalently attached to all available surface primary amines of ppi g2 and g3 to increase their lipophilicity. in the subsequent step, ppis were conjugated to the alkylcarboxylate groups of alkylcarboxylate-ppi derivatives to increase the number of surface primary amines. physicochemical properties of modified ppis were determined. transfection expe...
