this paper presents results of hydro-chemical processes controlling groundwater chemical composition, using an integrated application of hierarchical cluster analysis and factor analysis of a major ion data set of groundwater from mighan playa aquifer. cluster analysis classified samples into four clusters(a, b, c and d) according to their dominant chemical composition: cluster a (dominant comp...
genetic diversity is the basis of the natural evolution of plant breeding and biological system are important components of sustainability. the aim of this study was to evaluate 116 genotypes of triticum turgidum from seven countries in terms of morphological traits. the results showed that high significant differences among the genotypes. the correlation between grain yield ...
Speaker diarization includes two steps: speaker segmentation and speaker clustering. Speaker segmentation searches for speaker boundaries, whereas speaker clustering aims at grouping speech segments of the same speaker. In this work, the segmentation is improved by replacing the Bayesian Information Criterion (BIC) with a new iVector-based approach. Unlike BIC-based methods which trigger on any...
This paper presents two approaches to speaker clustering based on Probabilistic Linear Discriminant Analysis (PLDA) in the speaker diarization task. We refer to the approaches as the multifold-PLDA approach and the onefold-PLDA approach. For both approaches, simple factor analysis model is employed to extract low-dimensional representation of a sequence of acoustic feature vectors – so called i...
Latent variable models are useful tools for statistical data analysis in many applications. Examples of popular models include factor analysis, state-space models and independent component analysis. These types of models can be used for solving the source separation problem in which the latent variables should have a meaningful interpretation and represent the actual sources generating data. So...
background : to prepare safe and adequate blood supply to meet patients’ needs and ensure a sufficient number of regular blood donors, knowledge about factors encouraging people to donate blood regularly is essential. considering its importance, we aimed to identifying the effective factors of the return to blood donation in based on zero-inflated count regression models using bayesian approach...
Nowadays, one of the biggest problems of corporations is the lack of competitiveness. Thus, in this paper, we’re going to design a model for measuring corporate competitiveness. For designing this model, firstly literature of this field was reviewed and different theories, models, frameworks and approaches related to competitiveness at national and corporate levels were studied. According to th...
in order to study the correlation between morphophenological and quantitative traits with yield and to determine the most important traits for yield, 600 ecotypes of mung bean were evaluated in normal and limited irrigation conditions through augmented design. computation of correlation coefficients showed that in two conditions, number of pods per plant, harvest index and biological yield had ...
