The proper use of polymers as conditioners is a critical aspect of dewatering processes. In this study, we investigate their physical properties, i.e. size, density and fractal dimension and correlate them with their dewatering characteristics (bound water content, CST and SRF) on alum sludge with cationic polymer conditioning. Using CST measurement to determine the optimum polymer dose may lea...

In this paper, we study the performance limit of a wireless communication system over a fading channel. The system under study consists of 1) a finite-buffer discrete-time queueing system on the link layer, and 2) a rate-adaptive channel coding system on the physical layer. The objective of this paper is to analyze the relationship among data rate (R), packet error probability (E), and delay bo...

The fact that in experimental scurvy the concentration of ascorbic acid in the cellular elements of blood decreases more slowly than does the concentration in plasma (24) has led to the hypothesis that ascorbic acid might be bound’ to cellular protein (5, 6). There is, however, little direct evidence to support such a hypothesis. Saha, Majumdar, and Guha (7, 8) demonstrated the presence of boun...

A quantitative method was developed to measure the binding of fluorescent-labeled lentil (Lens esculenta Moench), pea (Pisum sativum L.), broad bean (Vicia faba L.), and jackbean (Canavalia ensiformis L., DC.) lectins to various Rhizobium strains. Lentil lectin bound to three of the five Rhizobium leguminosarum strains tested. The number of lentil lectin molecules bound per R. leguminosarum 128...

In this paper, by using the exponential convexity property of a barrier function, we propose an infeasible interior-point method for Cartesian P_*(k) horizontal linear complementarity problem over symmetric cones. The method uses Nesterov and Todd full steps, and we prove that the proposed algorithm is well define. The iteration bound coincides with the currently best iteration bound for the Ca...

there are different processes to form new words in every language, including compounding, derivation, inflection, etc. in compounding, two lexical stems form a compound. in derivation and inflection, new words are coined by affixation or some phonetic changes. this kind of affixation is applied on the simple or compound stem. here our compound stem is a bound compound stem, consisting of a noun...

In this paper, a new method for developing a lower bound on exact completion time distribution function of stochastic PERT networks is provided that is based on simplifying the structure of this type of network. The designed mechanism simplifies network structure by arc duplication so that network distribution function can be calculated only with convolution and multiplication. The selection of...

simultaneous estimation of the range and the angle of close emitters usually requires a multidimensional search. this paper proposes analgorithm to improve the position of an element for arrays designed on the basis of some certain or random rules. in the proposed method,one element moves along the same previous direction, maintaining its vertical distance from each source, to reach a constella...
