in this paper, we investigate a singular perturbation problem including a fourth order o.d.e. with general linear boundary conditions. firstly, we obtain the necessary conditions of solution of o.d.e. by making use of fundamental solution, then by compatibility of these conditions with boundary conditions, we determine that, for given perturbation problem, whether boundary layer is formed or not.

This paper proposes a robust model for optimizing collaborative reverse supply chains. The primary idea is to develop a collaborative framework that can achieve the best solutions in the uncertain environment. Firstly, we model the exact problem in the form of a mixed integer nonlinear programming. To regard uncertainty, the robust optimization is employed that searches for an optimum answer wi...

‎This paper aims at establishing the existence and uniqueness of solutions for a nonstandard variational-hemivariational inequality. The solutions of this inequality are discussed in a subset $K$ of a reflexive Banach space $X$. Firstly, we prove the existence of solutions in the case of bounded closed and convex subsets. Secondly, we also prove the case when $K$ is compact convex subsets. Fina...

The application of Artificial Intelligent approaches was introduced recently in protection of distribution networks. These approaches started with introducing Fuzzy Inference System (FIS), then using Artificial Neural Network (ANN).In this research, the application of Adaptive Neuro Fuzzy Inference System (ANFIS) for protection of bus bars will be illustrated. The ANFIS can be viewed as a fuzzy...

Dynamic video segmentation is an important research topic in computer vision. In this paper, we present a novel recursive Kernel Density Learning framework based video segmentation method. In the algorithm, local maximum in the density functions is approximated recursively via a mean shift method firstly. Via a proposed thresholding scheme, components and parameters in the mixture Gaussian dist...

Flip-Flop_1: Firstly, the old flip-flop construction that we choose to implement is the classic single edge triggered flip-flop (SETFF) which is shown in FIGURE 10.24 in the book " CMOS VLSI Design A Circuits and Systems Perspective " 4th Edition. The figure is shown below. Fig A-1 Resettable Flip-Flop The schematic that we construct is shown as follows: Fig A-2 Resettable Flip-Flop Schematic T...

A novel sphygmogram analyzer (SGA) with embedded medical advisory system is proposed to conquer the drawbacks of the existing commercial systems such as clumsy volume, awkward user-interface, and weak intelligence, etc. Firstly, benefited from the advanced embedded systems and micro-processing chips, the elementary components of SGA can be condensed into a tiny micro-system, which will greatly ...

In this study, inhibition of Microcystis aeruginosa by antialgal alleochemical gramine, was studied by analyzing algal metabolic activity (represented by esterase and total dehydrogenase activities) and cell ultrastructure (showing morphological and ultrastructure alterations using transmission electron microscopy and DNA ladder analysis). After gramine exposure, esterase and total dehydrogenas...

In this paper we present an overview of LIPS2008: Visual Speech Synthesis Challenge. The aim of this challenge is to bring together researchers in the field of visual speech synthesis to firstly evaluate their systems within a common framework, and secondly to identify the needs of the wider community in terms of evaluation. In doing so we hope to better understand the differences between the v...

The following new taxa of Meconematini from Guangxi province were described: Sinothaumaspis damingshanicus Wang, Liu, Li gen. & sp. nov., Aphlugiolopsis punctipennis Wang, Liu, Li gen. & sp. nov., Eoxizicus (Eoxizicus) curvicercus Wang, Liu, Li sp. nov., Meconemopsis paraquadrinotata Wang, Liu, Li sp. nov., Neocrytopsis? unicolor Wang, Liu, Li sp. nov., Xiphidiopsis (Dinoxiphidiopsis) expressa ...
