in static scheduling problem, where there is no change in situation, the challenge is that the large problems can be solved in a short time. in this paper, the static scheduling problem of automated guided vehicles in container terminal is solved by the network simplex algorithm (nsa). the algorithm is based on graph model and their performances are at least 100 times faster than traditional si...

BACKGROUND Herpesvirus infections often complicate the clinical course of patients with inflammatory bowel disease; however, invasive disease due to herpes simplex virus is distinctly uncommon. METHODS We present a case of herpes simplex virus colitis and hepatitis, review all the previously published cases of herpes simplex virus colitis, and discuss common clinical features and outcomes. We...

We determine the maximal hyperplane sections of regular n-simplex, if distance to centroid is fairly large, i.e. larger than midpoint edges. Similar results for n-cube and l1n-ball were obtained by Moody, Stone, Zach Zvavitch Liu Tkocz. The hyperplanes in these three cases are perpendicular vectors from vertices. For smaller distances -in a well-defined range- we show that at least locally maxi...

Abstract Finite elements with polynomial basis functions on the simplex a symmetric distribution of nodes should have unique representation. Unisolvence not only requires that number equals independent polynomials spanning space given degree, but also Vandermonde matrix controlling their mapping to Lagrange interpolating can be inverted. Here, necessary condition for unisolvence is presented sp...

A lot of research has been done to 1nd a faster (polynomial) algorithm that can solve linear programming (LP) problems. The main branch of this research has been devoted to interior point methods (IPM). The IPM outperforms the Simplex method in large LPs. However, there is still much research being done in order to improve pivoting algorithms. In this paper, we present a new approach to the pro...

Combined heat and power (CHP) production is an increasingly important energy production technology. CHP production is usually applied in back pressure plants, where the heat and power generation follows a joint characteristic. A CHP system may also comprise separate heat and power production facilities. Cost-efficient operation of a CHP system can be planned using an optimisation model based on...

The role of cell-mediated protection to herpes simplex infection was studied in vivo and in vitro. Sensitized spleen cells, obtained from syngeneic mice immunized with herpes simplex virus, protected recipient mice against lethal chal lenge with herpes simplex virus. Survival was signifivantly greater in challenged mice that received washed spleen cells from donor animals immunized with herpes ...

The maximum flow problem (MFP) is a fundamental model in operations research. The network simplex algorithm is one of the most efficient solution methods for MFP in practice. The theoretical properties of established pivot algorithms for MFP is less understood. Variants of the primal simplex and dual simplex methods for MFP have been proven strongly polynomial, but no similar result exists for ...

Maximum 200 words) As an emerging effective approach to nonlinear robust control, simplex sliding mode control demonstrates some attractive features not possessed by the conventional sliding mode control method, from both theoretical and practical points of view. However, no systematic approach is currently available for computing the simplex control vectors in nonlinear sliding mode control. I...
