This paper discusses how anodic pulses and periodic current reversion influence electrodeposition. Depending on the involved metal and electrolyte, very different effects can be observed and taken advantage of. The Wagner number, Wa, describing the current distribution is shown to be useful for predicting the throwing power at low frequencies of current reversion, even in complex electrochemical systems, but is less useful at higher frequencies. Passivation can occur due to oxide formation, super-saturation of metal salts or depletion of complexing agents at the electrode surface. Furthermore, dissolution and desorption processes in the anodic period can have strong influence on the succeeding cathodic electrocrystallisation affecting preferred crystal orientation, intrinsic stress and current efficiency. A literature survey is combined with experiments from silver plating from a cyanide bath. © 2014 Institute of Materials Finishing Published by Maney on behalf of the Institute. Source

This paper focuses on finding minimal complexities of decision trees representing rules defined for features and functionalities of online learning community. Because simultaneously minimizing all complexities is not always possible and this matches pattern of multiobjective optimization, Pareto optimal point is introduced for describing complexity distributions for selecting decision tree most suitable for system requirements. Unlike typical multiobjective optimization whose feasible space can be explicitly represented, feasible space for complexities of decision trees can only be implicitly reflected by relationships of subtables and associated objective functions due to the great number of possible trees. This paper provides a means of finding Pareto optimal points in implicit feasible space determined by objective functions defined for describing decision tree complexities by using graph and associated algorithm. The experimental results show that proposed algorithm yields valid results for finding Pareto optimal points. Copyright © 2015, AIDIC Servizi S.r.l. Source

In this study, based on the consideration of energy consumption, we take to improve the strategy of the MapReduce job scheduling algorithm, in order to reduce the average response time for task scheduling of interactive jobs in the network. In accordance with the job priority grouping to adjust the scheduling task response time which can reduce the impact of network congestion, with good results that increase the throughput of the system transferring data and computing power. © Maxwell Scientific Organization, 2013.
