In this paper, a semi-implicit finite-difference method is used to find the numerical solution of two-dimensional Coupled Burgers’ equation. The proposed scheme forms a system of linear algebraic difference equations to be solved at each time-step. The linear system is solved by direct method. Numerical results are compared with those of exact solutions and other available results. The present ...

A semi parametric profil~ likelihood method is proposed for estimation of sample selection models. The method is a two step scoring semi parametric estimation procedure based on index formulation and kernel density estimation. Under some regularity conditions, the estimator is asymptotically normal. This method can be applied to estimation of general sample selection models with multiple regime...

In this article, we unveil a new property of linear interference cancellation detectors. Particularly, we focus in this study on the linear parallel interference cancellation (LPIC) detector and show that it exhibits a semi-convergence property. The roots of the semi-convergence behavior of the LPIC detector are clarified and the necessary conditions for its occurrence are determined. In additi...

Response of five induced plant height mutants (dwarfs and semi-dwarfs) of barley to gibberellic acid (GA3) treatment was studied. The gibberellic acid response index (GRI) was calculated and based on this value, the mutants have been categorized as sensitive (high or moderate) or insensitive. The GRI value was highest for dwarf mutant followed by early maturing mutant with the former being high...

It is known that one of the essential building blocks of turbo codes is the interleaver and its design using random, semi-random (S-Random) and deterministic permutations. In this paper, two new types of turbo code interleavers, Enhanced Block S-Random (EBSR) interleaver is proposed. The design algorithm for the new interleaver is described in depth, and the simulation results are compared to t...

We consider an opportunistic communication system consisting of multiple independent channels with time-varying states. With limited sensing, a user can only sense and access a subset of channels and accrue rewards determined by the states of the sensed channels. We formulate the problem of optimal sequential channel selection as a restless multi-armed bandit process. We establish the indexabil...

—Canonical correlation analysis (CCA) is a powerful tool for analyzing multi-dimensional paired data. However, CCA tends to perform poorly when the number of paired samples is limited, which is often the case in practice. To cope with this problem, we propose a semi-supervised variant of CCA named “semiCCA”that allows us to incorporate additional unpaired samples for mitigating over ttng. The p...

The focus of Project HOOKAH is to improve the processing of the DEA-6 report, a semi-formatted report generated primarily by field agents, as well as legal staff, analysts, and others. DEA-6s are organized into case files, and are composed of multiple sections with varying amounts of formatting. Header fields are normally highly formatted, and indicate the subject, case, date, time, etc. There ...

It is well known that many bilateral basic hypergeometric identities can be derived from unilateral identities. Using Cauchy’s method [5, 15, 20, 21] one may obtain bilateral basic hypergeometric identities from terminating unilateral identities. Starting with nonterminating unilateral basic hypergeometric series, Chen and Fu [8] developed a method to construct semi-finite forms by shifting the...
