Excitatory and inhibitory amino acid binding sites in human dentate nucleus
(Elsevier, 1991-09-27)
Autoradiography of excitatory and inhibitory amino acid binding sites in human dentate nuclei indicated virtually no binding to N-methyl-d-aspartate (NMDA) or [gamma]-aminobutyric acidB (GABAB) binding sites, and a low ...
Approximating the Degree-Bounded Minimum Diameter Spanning Tree Problem
(Springer-Verlag; Springer Science + Business Media Inc., 2004-11)
We consider the problem of finding a minimum diameter spanning treewith maximum node degree $B$ in a complete undirected edge-weightedgraph. We provide an $O(sqrt{log_Bn})$-approximation algorithm for theproblem. Our ...
Hedging Uncertainty: Approximation Algorithms for Stochastic Optimization Problems
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2005-12-30)
We study two-stage, finite-scenario stochastic versions of several combinatorial optimization problems, and provide nearly tight approximation algorithms for them. Our problems range from the graph-theoretic (shortest path, ...
Integrated maintenance and production control of a deteriorating production system
(Kluwer Academic Publishers; Springer Science+Business Media, 2002-05)
We consider a make-to-stock production/inventory system consisting of a single deteriorating machine which produces a single item. We formulate the integrated decisions of maintenance and production using a Markov Decision ...
Control of a manufacturing system with random product yield and downward substitutability
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-09)
We consider a manufacturing system where the quality of the end product is uncertain and is graded into one of several quality levels after production. We assume stochastic demand for each quality level, stochastic production ...
Control of manufacturing networks which contain a batch processing machine
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-11)
We consider the control of a batch processing machine which is part of a larger manufacturing network of machines. Systems consisting of a batch processing machine and one or more unit-capacity machines in tandem are ...
Base-stock control for single-product tandem make-to-stock systems
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-01)
In this paper, we consider a multiple-stage tandem production/inventory system producing a single product. Processing time at each stage is assumed to have a general stationary processing time distribution. The cost of ...
On the structure of moving average processes
(Elsevier, 1977-07)
This paper uses Hilbert space methods to develop a rigorous proof that the sum of two uncorrelated moving average processes of order q1 and q2 is an MA process of order q [less, double equals] max (q1, q2). The methods ...
