A criterion for a three-stage network to be strictly non-blocking is presented which is very general in its application. The criterion distinguishes between channel grouping and link speedup as methods of increasing the bandwidth available to calls. It may be applied to both circuit-switched and packet-switched networks. The non-blocking conditions for various networks are shown to be special c...

Context. The problem of performance and scalability of web applications is challenged by most of the software companies. It is difficult to maintain the performance of a web application while the number of users is continuously increasing. The common solution for this problem is scalability. A web application can handle incoming and outgoing requests using blocking or non-blocking Input/Output ...

PURPOSE To investigate the influence of age on the neuromuscular blocking effect of cisatracurium. METHODS 90 patients with ASA I and II were assigned to the following groups according to their age: adults, children, and infants. Each group was subdivided into three subgroups according to the first dose of cisatracurium. Patients were administrated at a first dose of cisatracurium randomly, a...

BACKGROUND The diaphragm is resistant to competitive neuromuscular blocking agents. Because of the competitive mechanism of action of tubocurarine, the rate of hydrolysis of acetylcholine at the neuromuscular junction may modulate its neuromuscular blocking effect. The authors compared the neuromuscular blocking effect of tubocurarine on isolated diaphragm and extensor digitorum longus (EDL) mu...

Recently, the Maximum Satisfiability (MaxSAT) discovers a rapidly increasing number of practical applications in a wide range of different areas. Unsatisfiability-based MaxSAT algorithms have been put forward aimed at improving the performance of solving MaxSAT problem. In these algorithms, several excellent Boolean Satisfiability (SAT) solvers are employed to iteratively identify unsatisfiable...

External barium ions inhibit K+ currents of Xenopus oocytes expressing ShH4 delta 6-46, the non-inactivating deletion of the Shaker K+ channel. At the macroscopic level, Ba2+ block comprises both a fast and a slow component. The fast component is less sensitive to Ba2+ (apparent dissociation constant at 0 mV, K(0), approximately 19.1 mM) than the slow component and is also less voltage dependen...

In this paper we consider an open restricted queueing network with Poisson arrivals and exponential service times at stations and present an approximation method for analysis, made by node-by-node decomposition employing the concept of effective arrival rate and effective service rate. The steady state characteristics of the network system and of individual stations are obtained. Congestion due...

Centralized and Distributed methods are two connection management schemes in wavelength convertible optical networks. In the earlier work, the centralized scheme is said to have lower network blocking probability than the distributed one. Hence, much of the previous work in connection management has focused on the comparison of different algorithms in only distributed scheme or in only centrali...

Data integration is an important component of Big analytics. One the key challenges in data record linkage, that is, matching records represent same real-world entity. Because computational costs, methods referred to as blocking are employed a part linkage pipeline order reduce number comparisons among records. In past decade, range techniques have been proposed. Real-world applications require...
