Mason and Remmel introduced a basis for quasisymmetric functions known as the row-strict quasisymmetric Schur functions. This basis is generated combinatorially by fillings of composition diagrams that are analogous to the row-strict tableaux that generate Schur functions. We introduce a modification known as Young row-strict quasisymmetric Schur functions, which are generated by row-strict You...

This paper presents a decision tree pruning method for the model clustering of HMM-based parametric speech synthesis by cross-validation (CV) under the minimum generation error (MGE) criterion. Decision-tree-based model clustering is an important component in the training process of an HMM based speech synthesis system. Conventionally, the maximum likelihood (ML) criterion is employed to choose...

introduction: objective structured clinical examination (osce) is used for the evaluation of the clinical competence in medicine for which it is essential to measure validity and reliability. this study aimed to investigate the validity and reliability of osce for residents of obstetrics and gynecology at kermanshah university of medical sciences in 2011. methods: a descriptive-correlation stud...

This routine solves a complex sparse non-Hermitian system of linear equations: Ax 1⁄4 b; using an RGMRES (Saad and Schultz (1986)), CGS (Sonneveld (1989)), Bi-CGSTAB(‘) (Van der Vorst (1989), Sleijpen and Fokkema (1993)), or TFQMR (Freund and Nachtigal (1991), Freund (1993)) method. F11DSF allows the following choices for the preconditioner: no preconditioning; Jacobi preconditioning (Young (19...

We propose a new method of automatically creating nonuniform context-dependent HMM topologies by using the Minimum Description Length (MDL) criterion. Phonetic decision tree clustering is widely used, based on the Maximum Likelihood (ML) criterion, and creates only contextual variations. However, it also needs to empirically predetermine control parameters for use as stop criteria, for example,...

In data clustering, many approaches have been proposed such as K-means method and hierarchical method. One of the problems is that the results depend heavily on initial values and criterion to combine clusters. In this investigation, we propose a new method to cluster stream data while avoiding this deficiency. Here we assume there exists aspects of local regression in data. Then we develop our...

In the tropics, cowpea is often intercropped with maize. Little is known about the effect of the intercropped maize on N2-fixation by cowpea or how intercropping affects nitrogen fertilizer use efficiency or soil N-uptake of both crops. Cowpea and maize were grown as a monocrop at row spacings of 40, 50, 60, 80, and 120 cm and intercropped at row spacing of 40, 50, and 60 cm. Plots were fertili...
