T has been a revival of interest in traffic flow theory in the late 1990s, mostly because vehicle detectors have been installed at many highway locations throughout the world to record the passing of vehicles. The purpose of these detectors is to monitor congestion and provide information for possible control or to advise motorists of possible alternative routing. To understand the consequences...

The oxygen radical scavenger activity (ORSA) of [Cu(II)(Pir)(2)] (HPir = Piroxicam = 4-hydroxy -2- methyl -N-2- pyridyl -2H- 1,2-benzothiazine -3- carboxamide 1,1-dioxide) was determined by chemiluminescence of samples obtained by mixing human neutrophils (from healthy subjects) and [Cu(II)(Pir)(2)(DMF)(2)] (DMF = N,N -dimethylformammide) in DMSO/GLY/PBS (2:1:2, v/v) solution (DMSO = dimethylsu...

Methicillin resistant Staphylococcus aureus is considered a public health problem with a strong potential for dissemination and high rates of morbidity and mortality. In this study we describe bacteriological and epidemiological characteristics of Staphylococcus aureus in Manaus (Amazon region). During the one-year study period (2000-2001), sixteen cases of acute pyogenic multiple abscess were ...

-Genetic algorithms and tabu search have a number of significant differences. They also have some common bonds, often unrecognized. We explore the nature of the connections between the methods, and show that a variety of opportunities exist for creating hybrid approaches to take advantage of their complementary features. Tabu search has pioneered the systematic exploration of memory functions i...

The RANSAC [2] algorithm (RANdom SAmple Consensus) is a robust method to estimate parameters of a model fitting the data, in presence of outliers among the data. Its random nature is due only to complexity considerations. It iteratively extracts a random sample out of all data, of minimal size sufficient to estimate the parameters. At each such trial, the number of inliers (data that fits the m...

To improve the quality of SIFT feature matching, a mismatches removal method is proposed based on the collinearity property of the canonical correlation features. The influence of each match on the collineartiy degree is analyzed to find false matches. Firstly, a putative set of matches is obtained based on distances between SIFT feature descriptors. Secondly, the spatial relationship of matche...

Heterokaryon (vegetative) incompatibility, governing the fusion of somatic hyphal filaments to form stable heterokaryons, is of interest because of its widespread occurrence in fungi and its bearing on cellular recognition. Conventional investigations of the genetic basis of heterokaryon incompatibility in N . crassa are difficult because in commonly used stocks differences are present a t seve...

Tropical forests support extensive biodiversity (Pimm & Raven, 2000) and maintain globally significant carbon stocks (Pan et al., 2011). Yet these are subject to widespread selective logging (Blaser 2011), which is the primary driver of tropical forest degradation (Hosonuma 2012; Pearson 2017). Selective involves harvesting commercially valuable species a minimum cutting size, leaving behind no...

The physical characteristics and performance attributes of absorbent gauze and spunlaced nonwovens used formedical/surgical applications are reviewed. Because the manufacturing lines for spunlacing are versatile and highlyproductive, nonwoven products from this process are highly engineered and may have superior performancecharacteristics relative to gauze products. Dressings ma...

Communications systems often have many types of users. Since they share the same resource, there is a con ict in their needs. This con ict leads to the imposition of controls on admission or elsewhere. In this paper, there are two types of customers, GP (Guaranteed Performance) and BE (Best E ort). We consider an admission control of GP customer which has two roles. First, to guarantee the perf...
