The cost-effective operationof an analyticalsystemdepends on quality-control (QC) practices such as the QC procedure itself (control rules, number of control measurements);the batch size or the run length; and the use of bracketed, nonbracketed,or pre-controlmodesof operation.Predictive value models that predict the defect rate and test yield of each test, as well as of the system as a whole, h...

Training supervised machine learning models requires labeled examples. A judicious choice of examples is helpful when there a significant cost associated with assigning labels. This article improves upon promising extant method – Batch-mode Expected Model Change Maximization (B-EMCM) for selecting to be regression problems. Specifically, it develops and evaluates alternate strategies adaptively...

Rapid growth of Internet spawns many group oriented multicast applications like Internet pay TV, news dissemination and stock quote system. The fortes of these applications are the support of dynamic, scalable group membership and group members are geographically divergent. As members of the group move in and out, an imperative cryptographic rekeying model should be applied to preserve the conf...

We study a version of the proximal gradient algorithm for which the gradient is intractable and is approximated by Monte Carlo methods (and in particular Markov Chain Monte Carlo). We derive conditions on the step size and the Monte Carlo batch size under which convergence is guaranteed: both increasing batch size and constant batch size are considered. We also derive non-asymptotic bounds for ...

the objective of this research was to investigate the influence of the over-expression of recombinant interferon-g during high cell density cultivation on cellular characteristics of recombinant e. coli. batch and fed-batch culture techniques were employed to grow escherichia coli bl21 for production of human gamma-interferon in pet expression system. final cell densities in batch and fed-batch...

In order to determine the efficiency of a production system, batch size and throughput are two important parameters that must be considered. In order to ensure system efficiencies and meet optimum utilization, batch size must conform to the throughput. The use of Queuing Network Theory to study the effect of batch size and throughput in optimizing the resource utilization, particularly machine ...

This paper presents two polynomial time algorithms for the constant capacitated lot sizing problem with a batch production. We give several optimality properties for the general problem. Assuming constant production capacity, constant batch size and WagnerWhitin cost structure, we derive O(T ) and O(T ) time algorithms respectively for the case with production capacity multiple of the batch siz...
