Impurity Distribution During Electrolytic Refining of Antimony
Metallurgist, 2021Results of electrolysis of antimony (99.56% Sb) in a sulfate-fluoride electrolyte are provided. Electrolysis parameters and distribution of 20 associated elements between the cathode metal, sludge, and electrolyte are determined. Phase composition of the sludge formed is established, and it is shown that presence of intermetallic compounds (NiSb and ...

Asymptotic Refinements in Bayesian Distributed Detection
Proceedings. IEEE International Symposium on Information Theory, 2005The performance of a parallel distributed detection system is investigated as the number of sensors tends to infinity. It is assumed that the i.i.d. sensor data are quantized locally into m-ary messages and transmitted to the fusion center for Bayesian binary hypothesis testing.

Distribution of Refined Petroleum Products in Russia
Post-Soviet Geography and Economics, 1999A Western specialist on Russia's oil and gas industries, together with two Russian analysts, examines the development of the distribution system for refined petroleum products in post-Soviet Russia. Such “downstream” activities, oriented largely toward the domestic market, are an increasingly important component of the growth strategies of Russia's ...

Tetrahedral Mesh Refinement in Distributed Environments
2006 International Conference on Parallel Processing Workshops (ICPPW'06), 2006The adaptive mesh refinement is one of the main techniques used for the solution of partial differential equations. Since 3-dimensional structures are more complex, there are few refinement methods especially for parallel environments. On the other hand, many algorithms have been proposed for 2-dimensional structures.

Refinement of Size Distributions for Primary Crystallizations
MRS Proceedings, 1997ABSTRACTThe microstructure developed in primary crystallizations is studied under realistic conditions. The primary crystallization of an amorphous alloy is modeled by considering the thermodynamics of a metastable phase transition and the kinetics of nucleation and crystal growth under isothermal annealing.

Pb distribution in multistep bismuth refining products
Inorganic Materials, 2011Significant amounts of lead impurities have been removed from bismuth using a multistep refining process involving bismuth electrorefining in a hydrochloric acid solution, melting of a cathodic bismuth sponge, and pyrometallurgical processing of molten bismuth in an inert atmosphere.

Dynamic networking refinement in distributed systems
Proceedings Third International Conference on Peer-to-Peer Computing (P2P2003), 2004Networking forms an essential part of distributed systems and reliable point-to-point communication is one of the main utilization of distributed networking systems. We discuss new techniques for improving networking in distributed systems under a sequence of operations, such as inserting and deleting a link between two nodes.

Distribution feeder reconfiguration with refined genetic algorithm
IEE Proceedings - Generation, Transmission and Distribution, 2000A refined genetic algorithm for a distribution feeder reconfiguration to reduce losses is presented. The problem is optimised in a stochastic searching manner similar to that of the conventional GA. The initial population is determined by opening the switches with the lowest current in every mesh derived in the optimal power flow (OPF), with all ...

Refining Interactions in a Distributed System
2001We identify a type of refinement that we call interaction refinement that is very useful in designing distributed systems. An interaction refinement step is one in which a system designer decides to implement a given 'high-level' interaction as a particular sequence of 'low-level' interactions.

On distributed successive refinement with lossless recovery
2014 IEEE International Symposium on Information Theory, 2014The problem of successive refinement in distributed source coding and in joint source-channel coding is considered. The emphasis is placed on the case where the sources have to be recovered losslessly in the second stage. In distributed source coding, it is shown that all sources are successively refinable in sum rate, with respect to any (joint ...
