In this article, we consider the set covering problem with conflict constraints, i.e., from each conflicting pair of columns at most one column can appear in feasible solution. For problem, propose appropriate pre-processing techniques and several families Valid Inequalities (VIs) for corresponding integer programming model that result simultaneous presence constraints stable (conflict) constra...

The Small, Modular Advanced High Temperature Reactor (SmAHTR) is a preconceptual design for fluoride salt-cooled small modular reactor (SMR) [1]. In this paper, stylized 2D benchmark problem set has been created based on SmAHTR. Certain gaps and considerations in burnable poison control rod content were unspecified/undetermined the design, but those filled set. With features, could then be used...

background: lateral ridge split technique is a way to solve the problem of the width in narrow ridges with adequate height. simultaneous insertion of dental implants will considerably reduce the edentulism time. materials and methods: twenty-five patients who were managed with ridge splitting technique were enrolled. thirty-eight locations in both jaws with near equal distribution in quadrants ...
