Batch sizing in different planning period is categorized as a classical problem in production planning, that so many exact & heuristic methods have been proposed to solve this problem, each of which considering various aspects of the original problem. The solution obtained from majority – e.g. MRP – is in this format that there may be some periods of idleness or each period should produce a...

Text segmentation is the process of converting information in unstructured text into structured records. This is an important problem since structured data is amenable to efficient query processing. CRFs are a class of discriminative probabilistic models that are gaining acceptance as an effective computing machinery for text segmentation. An important aspect of CRFs is learning model parameter...

abstract the utility of carbon paste electrode for the determination of flavoxate hcl modified with flavoxate-tetraphenylborate (flx-tpb) and flavoxate-phosphotungestic acid (flx-pta) ion-pairs in batch mode is demonstrated. the electrodes revealed a nernstian response over a wide concentration ranges 1.39×10-5-1x10-2 mol l-1 and1×10-5-1x10-2 mol l-1 using flx-tpb and flx-pta, respectively. the...

The self-cycling fermentation (SCF) technique was applied to a culture of Acinetobacter calcoaceticus RAG-1. This method was shown to result in synchronization of the cells, achieving a 77% improvement in cell synchrony over that of the batch case. Cellular occurrences, averaged out by asynchronous batch cultures, were magnified by the temporal alignment of metabolic events brought about by the...

Isotope fractionation is a promising tool for quantifying methane oxidation in landfill cover soils. For good quantification an accurate determination of the isotope fractionation factor (alpha) of methane oxidation based on independent batch experiments with soil samples from the landfill cover is required. Most studies so far used data analysis methods based on approximations of the Rayleigh ...

The object of this study was to develop hydroxypropyl methylcellulose (HPMC) based cephalexin extended release tablet, which can release the drug for six hours in predetermined rate. Twenty-one batches of cephalexin tablets were prepared by changing various physical and chemical parameters, in order to get required theoretical release profile. The influences of HPMC, microcrystalline cellulose ...

This paper presents a graph-theoretic technique for scheduling of multipurpose batch processes with the objective of maximizing throughput over a fixed time horizon. The presented technique is based on the S-graph framework which embeds the necessary scheduling information pertaining to recipes of different batches and possible resource allocation. The distinct feature of this contribution is t...

We derive cost formulae for three diierent parallelisation techniques for training both supervised and unsupervised networks. These formulae are parameterised by properties of the target computer architecture. It is therefore possible to decide both which technique is best for a given parallel computer, and which parallel computer best suits a given technique. One technique, exemplar parallelis...
