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...

By a sequence of numerical experiments we demonstrate that generic trian-gulations of the D−sphere for D > 3 contain one singular (D−3)−simplex. The mean number of elementary D−simplices sharing this simplex increases with the volume of the triangulation according to a simple power law. The lower dimension subsimplices associated with this (D − 3)−simplex also show a singular behaviour. Possibl...

Cerebrospinal fluid samples from 257 patients with suspected herpes simplex virus encephalitis were prospectively analyzed by herpes simplex virus polymerase chain reaction. The polymerase chain reaction indicated herpes simplex virus encephalitis in 9 serologically proven cases and in 14 additional patients. Increased polymerase chain reaction signals were observed together with more severe ne...

Generalizations of the well-known simplex method for linear programming are available to solve the piecewise linear programming problem and the linear fractional programming problem. In this paper we consider a further generalization of the simplex method to solve piecewise linear fractional programming problems unifying the simplex method for linear programs, piecewise linear programs, and the...

The genetic relationships among 9 taxa of Anisakis Dujardin, 1845 (A. simplex (sensu stricto), A. pegreffii, A. simplex C., A. typica, A. ziphidarum, A. physeteris, A. brevispiculata, A. paggiae, and Anisakis sp.) were inferred from sequence analysis (629 bp) of the mitochondrial cox2 gene. Genetic divergence among the considered taxa, estimated by p-distance, ranged from p = 0.055, between sib...

For the early diagnosis of herpes simplex encephalitis IgG and IgM antibodies to herpes simplex virus in cerebrospinal fluid were measured by an enzyme linked immunosorbent assay (ELISA) and a local production index was calculated. Using these three criteria, 31 cases of various neurological illnesses were analysed. All eight cases of herpes simplex encephalitis were diagnosed correctly in the ...

Herpes simplex is a common viral infection of the skin or mucous membranes. The lesions caused by this infection are often painful, burning, or pruritic, and tend to recur in most patients. Shortterm treatment with acyclovir can accelerate the healing of an acute outbreak, and continuous acyclovir therapy is often prescribed for people with frequent recurrences. While this drug can reduce the r...

We present a new positive lower bound for the minimum value taken by a polynomial P with integer coefficients in k variables over the standard simplex of R, assuming that P is positive on the simplex. This bound depends only on the number of variables k, the degree d and the bitsize τ of the coefficients of P and improves all previous bounds for arbitrary polynomials which are positive over the...

Herpes simplex virus infection of the central nervous system is still a significant cause of morbidity and often mortality. Changes of central nervous system are results of primary infection or activation of latent HSV-1, HSV-2. Neurological deficits often follow encephalitis herpetica. The application of PCR is prompt and specific diagnosis of herpes simplex virus infections of the brain. Adva...

The free-living marine nematode Dracognomus simplex (Gerlach, 1954) Allen &Noffsinger, 1978 was studied by scanning electron microscopy (SEM). The morphology of males and females is described and illustrated in detail. In addition to the typical and modified adhesion tubes, a new type of posterior adhesion tube was discovered. A neotype is proposed for Dracognomus simplex, and D. simplex sensu ...
