Statistical topic models have traditionally assumed that a document is an indivisible unit for the generative process, which may not be appropriate to handle documents that are relatively long and show an explicit multi-topic structure. In this paper we describe a generative model that exploits a given decomposition of documents in smaller, topically cohesive text units, or segments. The key-id...

A scheme for modeling the F0 contour for different types of intonation units for the Slovene language is presented. It is based on results of analyzing F0 contours, using a quantitative model. Data from ten speakers was collected, resulting in a large corpora, mainly of declarative sentences. A way of generating the F0 contour for given utterances was defined, using only the text of the utteran...

Some crucial process variables in fermentation process could not be measured directly. Soft sensor technology provided an effective way to solve the problem. There has been considerable interest in modeling a soft sensor by using artificial neural network (ANN) in bioprocess. To generate a more efficient soft sensor model, we proposed a novel soft sensor model based on artificial neural network...

4.1 CHAPTER SUMMARY The effect of the variables of polydimethylsiloxane (PDMS) soft segment length, hard segment type and content as well as choice of chain extender (its MW and symmetry) on the morphology of segmented polyurethane and polyurea copolymers was investigated. The methods of dynamic mechanic analysis, small angle x-ray scattering, atomic force microscopy, and mechanical testing wer...

Novel segmented thermoplastic polyurethane (TPU) copolymers were synthesized using two-step solventless bulk polymerization. 4,4’-methylenediphenyl diisocyanate (MDI) and 1,4-Butanediol (BDO) were used to form hard segment of TPU and α,ω-dihydroxy-[poly(propyleneoxide)-poly (dimethylsiloxane)-poly(propyleneoxide)] (α,ω-dihydroxy-(PPO-PDMS-PPO)) was used to form soft segment of TPU, where the mo...

In this paper a modified version of the Akthar’s method for online secondary path modeling in active noise control systems is proposed. The proposed method defines two variable step sizes for control filter and modeling filter. The control filter step size μm is adapted by using the variable threshold value Tj and the modeling filter step size μm is adapted by using a new modified variable step...
