‎let $g=(v(g),e(g))$ be a graph‎, ‎$gamma_t(g)$. let $ooir(g)$ be the total domination and oo-irredundance number of $g$‎, ‎respectively‎. ‎a total dominating set $s$ of $g$ is called a $textit{total perfect code}$ if every vertex in $v(g)$ is adjacent to exactly one vertex of $s$‎. ‎in this paper‎, ‎we show that if $g$ has a total perfect code‎, ‎then $gamma_t(g)=ooir(g)$‎. ‎as a consequence, ...

In this paper we introduced the concepts of global domination number and domatic in product fuzzy graph is denoted by γg(G) dg(G), respectively determine for several classes obtain Nordhaus-Gaddum type results parameter. Further, some bounds dg(G) are investigated. Also relations between γg(G)(dg(G)) other known parameter Product graphs Finally introduce concept full about done.

Let D=(V(D),A(D)) be a finite, simple digraph and k positive integer. A function f:V(D)→{0,1,2,…,k+1} is called [k]-Roman dominating (for short, [k]-RDF) if f(AN−[v])≥|AN−(v)|+k for any vertex v∈V(D), where AN−(v)={u∈N−(v):f(u)≥1} AN−[v]=AN−(v)∪{v}. The weight of [k]-RDF f ω(f)=∑v∈V(D)f(v). minimum on D the domination number, denoted by γ[kR](D). For k=2 k=3, we call them double Roman number tr...

The present paper, which is intended for a diverse audience of evaluation researchers, applied social scientists and research funders, provides a broad overview of the conceptual and statistical issues involved in using multi-site randomized trials to learn about and from variation in program effects across individuals, across policy-relevant and theoretically-relevant subgroups of individuals ...

In Multipregnancies, The careful control of Number of follicles in stimulation cycles and Number of embryos transferred in ART cycles is so important. Just twin pregnancies are reason for racial death (12- 15%). The risk for CP in twin pregnancies is 8 times more and for Triple is 47 times more than simple ones.Approximately all prenatal problems increase in multiple pregnancies and therefore t...

The purpose of this master's thesis was to explore the circuit design space (speed, area, power) of conventional binary arithmetic and to suggest improvements or alternatives to this arithmetic. The alternatives to the binary arithmetic focused on was the Signed-Digit (SD) number system, the Residue Number System (RNS) and the combination of these two systems (RNS+SD). The work resulted in new ...
