These days, ongoing research towards interactivity to break the persevering batch processing paradigm in grid computing can be seen. Batch processing means: submit a job to a queue, process it and, only when the job is finished, analyse the results. By extending grid middleware through an interactive jobmanager, a novel approach to support applications which require interactive connections is p...

A new, general method for the determination of batch distillation regions of heteroazeotropic distillation is suggested. The method proposed, which means the extension of the method of Pham and Doherty, takes into consideration the possibility of the withdrawal of any fraction of either liquid phase from the decanter as distillate. The simplified and rigorous simulation calculations were carrie...

Fast dissolving film of levocetrizine dihydrochloride were prepared by solvent casting method by using Maltodextrin & HPMC E15 as the main film forming polymers.To decrease the disintegration time,concentration of maltodextrin & HPMC E15 were optimized be using 2 factorial design. Disintegration time, drug release pattern, mouth dissolving time and content uniformity were also evaluated. Compat...

Spell checking is considered a solved problem, but with the rapid development of the natural language processing the new results are slowly extending the means of spell checking towards grammar checking. In this article I review some of the spell checking error classes in a broader sense, the related problems, their state-of-the-art solutions and their different nature on different types of lan...

Learning is a flexible and effective means of extracting the stochastic structure of the environment. It provides an effective method for blind separation and deconvolution in signal processing. Two different types of learning are used, namely batch learning and on-line learning. The batch learning procedure uses all the training examples repeatedly so that its performance is compared to the st...

In this paper we discuss the asymptotic properties of the most commonly used variant of the backpropagation algorithm in which network weights are trained by means of a local gradient descent on examples drawn randomly from a fixed training set, and the learning rate TJ of the gradient updates is held constant (simple backpropagation). Using stochastic approximation results, we show that for TJ...

Self-organizing maps (SOM) have been successfully applied in many fields of research. In this paper, we demonstrate the use of SOM-based method for the analysis of Expandable PolyStyrene (EPS) batch process. To this end, a data set of EPS-batch process was used for training a SOM. Reference vectors of the SOM were then classified by K-means algorithm into six clusters, which represent product t...

This paper suggests a method to control the particle size distribution in semi-batch emulsion homopolymerizations under structural plant-model mismatch. In this approach, firstly a nominal monomer feed input trajectory is applied to the plant up to a predefined time instant after the start of the batch (mid-course). By means of a calorimetric observer, all states of the system except the partic...

A rapid isocratic high-pressure liquid chromatography procedure for the analysis of ethosuximide, phenobarbitone, phenytoin, and carbamazepine in serum is described. The method employs a single extraction from serum; alumina treatment of this extract eliminates interference from fast-eluting compounds, allowing rapid chromatography. A linear response is obtained for drug concentrations up to th...
