Previous studies demonstrated the environmental and economic benefits of treating lead(II)-contaminated water streams with ferrihydrite in multiple equilibrium sorption stages. In this work, multistage ferrihydrite sorption systems were evaluated for their effectiveness in reducing single-solute zinc(II) (Zn(II)) concentrations in contaminated water streams to very low levels. As for lead(II) (...

Performance evaluation, using both analytical and simulation models, of multistage priority interconnection networks with a single layer or more layers is presented. The configurations of the networks under study apply a conflict drop resolution strategy. Our analytical models are based on a more realistic assumption. A new analysis is given and is verified by simulation results. In single netw...

This paper is concerned with linear superposition systems in which all components of the superimposed signal are coded with an identical binary low-density parity-check (LDPC) code. We focus on the design of decoding and computing algorithms. The main contributions of this paper include: 1) we present three types of iterative multistage decoding/computing algorithms, which are referred to as de...

Few studies have demonstrated the practical application of surface complexation models, calibrated with fundamental macroscopic and spectroscopic metal sorption data, in helping to solve industrial trace metal emissions problems. In this work, multistage ferrihydrite sorption systems are evaluated for their effectiveness in reducing single-solute lead(II) [Pb(II)] concentrations in contaminated...

Parallel processing is an efficient form of information processing system, which emphasizes the exploitation of concurrent events in the computing process. To achieve parallel processing it’s required to develop more capable and costeffective systems. In order to operate more efficiently a network is required to handle large amount of traffic. Multi-stage Interconnection Network plays a vital r...

objective: this research was conducted to investigate the relationship between behavioral activation-inhibition systems and bullyingvictimization behaviors among adolescents. method: this was a correlational and cross-sectional study. two hundred and thirty school boys were selected randomly by multistage cluster sampling method, and participated in this research. this sample responded to a dem...

ÐAll-to-all personalized exchange is one of the most dense collective communication patterns and occurs in many important applications in parallel computing. Previous all-to-all personalized exchange algorithms were mainly developed for hypercube and mesh/torus networks. Although the algorithms for a hypercube may achieve optimal time complexity, the network suffers from unbounded node degrees ...
