Abstract:
Let G=(V(G),E(G)) be a simple graph. A set S⊆ V(G) is a restrained dominating set if every vertex not in S is adjacent to a vertex in S and to a vertex in V G ∖ S. It is a super restrained dominating set if for every vertex u∈V G ∖S, there exists v∈S such that NG v ∩(V G ∖S)={u}. The minimum cardinality of a super restrained dominating set in G, denoted by γspr(G), is called the super restrained domination number of G. In this paper, we initiate the study of the concept and give the characterization of the corona of two graphs and give some important results.

Title:

Abstract:
The main aim of this paper is to review the performance of aluminium-based sacrificial anode in the effect of zinc addition in sea water. The performance of aluminium anode is largely dependent on alloy composition and a good understanding of the relationships between the metallurgy and the anodic response of the alloys. Recent Researches show that with certain metallic alloys added significantly improves anode life and reduce costs.

Abstract:
Dexterous and reliable manipulation plays an important role in working robots. Manipulator tasks such as assembly of objects and operation of tools can generally be divided into several motion primitives. We call these “skills” and explain how most manipulator tasks can be composed of skill sequences. Skills are also used to compensate for errors both in the geometric model and in manipulator motions. There are dispensable data in the shapes, positions and orientations of objects that are not required to achieve skill motions in a task. Therefore, we can simplify geometric models by considering the dispensable data in a given skill motion. This paper proposes a method using simplified geometric modeling to easily understand skill-based manipulation involving high-level techniques. The procedures can clarify which parts of objects change at each step of a manipulation task. This method can also be applied to error recovery techniques for the overall manipulation system, since when the scope to be observed at each step of a task becomes clear, reliability improves.
