Selection of Suitable Features for Modeling the Durations of Syllables  [PDF]
Krothapalli S. Rao, Shashidhar G. Koolagudi
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.312129
Abstract: Acoustic analysis and synthesis experiments have shown that duration and intonation patterns are the two most important prosodic features responsible for the quality of synthesized speech. In this paper a set of features are proposed which will influence the duration patterns of the sequence of the sound units. These features are derived from the results of the duration analysis. Duration analysis provides a rough estimate of features, which affect the duration patterns of the sequence of the sound units. But, the prediction of durations from these features using either linear models or with a fixed rulebase is not accurate. From the analysis it is observed that there exists a gross trend in durations of syllables with respect to syllable position in the phrase, syllable position in the word, word position in the phrase, syllable identity and the context of the syllable (preceding and the following syllables). These features can be further used to predict the durations of the syllables more accurately by exploring various nonlinear models. For analying the durations of sound units, broadcast news data in Telugu is used as the speech corpus. The prediction accuracy of the duration models developed using rulebases and neural networks is evaluated using the objective measures such as percentage of syllables predicted within the specified deviation, average prediction error (µ), standard deviation (σ) and correlation coefficient (γ).
Real Time Prosody Modification  [PDF]
Krothapalli Sreenivasa Rao
Journal of Signal and Information Processing (JSIP) , 2010, DOI: 10.4236/jsip.2010.11006
Abstract: Real time prosody modification involves changing the prosody parameters such as pitch, duration and intensity of speech in real time without affecting the intelligibility and naturalness. In this paper prosody modification is performed using instants of significant excitation (ISE) of the vocal tract system during production of speech. In the conventional prosody modification system the ISE are computed using group delay function, and it is computationally intensive task. In this paper, we propose computationally efficient methods to determine the ISE suitable for prosody modification in interactive (real time) applications. The overall computational time for the prosody modification by using the proposed method is compared with the conventional prosody modification method which uses the group delay function for computing the ISE.
Factor XI deficiency in Indian Bos taurus, Bos indicus, Bos taurus x Bos indicus crossbreds and Bubalus bubalis

Genetics and Molecular Biology , 2007, DOI: 10.1590/S1415-47572007000400013
Abstract: we investigated the occurrence of factor xi (fxi) deficiency syndrome in the following indian dairy animals: bos taurus holstein-friesian and jersey cattle, bos indicus indian cattle breeds, b. taurus x b. indicus crossbreds and the river buffalo bubalus bubalis. factor xi deficiency is an autosomal recessive bleeding disorder known to affect holstein cattle worldwide. a total of 1001 dairy animals, mainly bulls, were genotyped to detect the mutation within exon 12 of the gene encoding for factor xi. two holstein bulls were detected as heterozygous (carrier) for fxi deficiency, giving a carrier frequency of 0.6% in indian holstein cattle. none of the other cattle or buffalo breeds was found to be a carrier for fxi. sequence comparison between normal and heterozygous animals revealed that there is a 77 base pair insertion fragment (at (a)29 taaag (a)27 gaattattaattct) within exon 12 of the fxi gene. both sequences were submitted to the national center for biotechnology information (ncbi) genbank and assigned the accession numbers dq438908 for normal holstein friesian animals and dq438909 for heterozygous holstein friesian animals.

Software Selection in Manufacturing Industries Using a Fuzzy Multiple Criteria Decision Making Method, PROMETHEE  [PDF]
R. V. RAO, T. S. RAJESH
Intelligent Information Management (IIM) , 2009, DOI: 10.4236/iim.2009.13023
Abstract: This paper presents an effective decision making framework for software selection in manufacturing industries using a multiple criteria decision making method, Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE). The method is improved in the present work by integrating with analytic hierarchy process (AHP) and the fuzzy logic. Fuzzy logic is introduced to handle the imprecision of the human decision making process. The proposed decision making framework is practical for ranking competing software products in terms of their overall performance with respect to multiple criteria. An example is included to illustrate the approach.
A Novel Method of Using API to Generate Liaison Relationships from an Assembly  [PDF]
Arun Tom Mathew, C. S. P. Rao
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.32021
Abstract: A mechanical assembly is a composition of interrelated parts. Assembly data base stores the geometric models of indi-vidual parts, the spatial positions and orientations of the parts in the assembly, and the relationships between parts. An assembly of parts can be represented by its liaison which has a description of its relationships between the various parts in the assembly. The problem is to not only make the information available but also use the relevant information for making decisions, especially determination of the assembly sequence plan. The method described in this paper ex-tracts the feature based assembly information from CAD models of products and build up liaisons to facilitate assembly planning applications. The system works on the assumption that the designer explicitly defines joints and mating condi-tions. Further, a computer representation of mechanical assemblies in the form of liaisons is necessary in order to automate the generation of assembly plans. A novel method of extracting the assembly information and representing them in the form of liaisons is presented in this paper.
Exchange Rate Market Sentiment Analysis of Major Global Currencies  [PDF]
K. S. Madhava Rao, Anjana Ramachandran
Open Journal of Statistics (OJS) , 2014, DOI: 10.4236/ojs.2014.41006
Abstract:

The paper deals with the analysis of market sentiments in exchange rates which are of great interest to trading individuals and institutional investors. For example, an institutional investor or a trading individual makes better investments and minimizes losses when equipped with an understanding of market sentiments in weekly or monthly exchange returns. In the approach suggested here, a typical market sentiment is defined on the basis of the certain function of the mean and the standard error of the logarithm of the ratio of successive daily exchange rates. Based on this surmise, the market sentiments are classified into various states, whereby states are defined according to the perceptions of the market player. A multinomial probability model is built to capture the uncertainties in market sentiments. Two asymptotically distribution-free tests, namely the chi-square and the likelihood ratio test of goodness of fit for the hypothesis of the symmetry in market sentiments are suggested. Two different measures of market sentiments are proposed. The approach advocated here will be of interest to researchers, exchange rate traders and financial analysts. As an application of the proposed line of approach, we analyze weekly market sentiments that govern exchange rates of the major global currenciesEUR, GBP, SDR, YEN, ZAR, USD, data from 2001-2012. Some interesting conclusions are revealed based on the data analysis.
