A new Face Recognition (FR) system based on Singular Values Decomposition (SVD) and pseudo 2D Hidden Markov Model (P2D-HMM) is proposed in this paper. The state sequence of the pseudo 2D HMM are modeled independently which gives superior results when compared to regular 2D HMMs. As a novel point presented here, we have maintained a limited number of quantized Singular Values Decomposition (SVD)...

Equity markets are increasingly seen as important sources of investment funds in many emerging economies. Furthermore, many countries see the development of such markets as a means to facilitate both foreign equity portfolio investment and foreign direct investment (FDI). This may occur through acquisition of shareholdings in domestic companies, which supplements the low levels of funding from ...

Misspecified models, noisy betas, and weak instruments are well-known problems in finance and can lead to poor test performance. In this paper, we introduce a new technique for estimating and testing cross-sectional asset pricing models that addresses these problems. We apply our technique to three popular cross-sectional asset pricing models: CAPM, the Fama-French three-factor model, and the C...

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

The main goal of this study was to analyze the psychometric properties of the Perception of Parents Scale (POPS) developed by Robbins (1994), with a sample of middle-adolescents with ages between 14 and 18 years. The confirmatory factor analysis was conducted to examine the reliability and validity of a three-dimension model of adolescents’ perception of mother and father based on perspective o...

This paper introduces a method for decomposing the component responses of the evoked potentials. The decomposition was realized by zero-pole modeling of the evoked potentials in the discrete cosine transform (DCT) domain. It was found that the DCT coefficients of a component response in the evoked potentials could be modeled sufficiently by a second order transfer function in the DCT domain. Th...

The findings show that the influence of investor sentiment is significa...

The presumed totipotency of plant cells leads to questions about how specific stem cell lineages and terminal fates could be established. In the Arabidopsis stomatal lineage, a transient self-renewing phase creates precursors that differentiate into one of two epidermal cell types, guard cells or pavement cells. We found that irreversible differentiation of guard cells involves RETINOBLASTOMA-R...
