This paper presents a new method for estimating the optical flow field using the MRF modeling. In the MRF framework, the estimation problem amounts to the minimization of an energy function. We propose an Evolutionary Algorithm (EA) method to solve this minimization problem. It is based on a divide-and-conquer strategy which adequately uses the markovian property. Experimental results show the ...

The redox potentials have been determined for nine azaanthraquinones in phosphate buffer at pH 7.2 by means of cyclic voltammetry. A definite correlation has been found between the redox potentials and the inhibitory effects of the azaanthraquinones on Epstein-Barr virus early antigen (EBV-EA) activation. It has further been shown that the correlation can be made better by introducing an electr...

Cyclooxygenase-2 (COX-2) is an enzyme that plays a key role in inflammatory processes. Classically, this enzyme is upregulated in inflammatory situations and is responsible for the generation of prostaglandins (PGs) from arachidonic acid (AA). One lesser-known property of COX-2 is its ability to metabolize the endocannabinoids, N-arachidonoylethanolamine (AEA) and 2-arachidonoylglycerol (2-AG)....

It is important to estimate the ridge distance accurately, an intrinsic texture property of a fingerprint image. Up to now, only several articles have touched directly upon ridge distance estimation. Little has been published providing detailed evaluation of methods for ridge distance estimation, in particular, the traditional spectral analysis method applied in the frequency field. In this pap...

objective(s): global cerebral ischemia-reperfusion (gcir) causes disturbances in brain functions as well as other organs such as kidney. our aim was to evaluate the protective effects of ellagic acid (ea) on certain renal disfunction after gcir. materials and methods: adult male wistar rats (n=32, 250-300 g) were used. gcir was induced by bilateral vertebral and common carotid arteries occlusio...

Two-dimensional (2D) halide perovskites have outstanding optoelectronic properties, and they feature a variety of organic cation spacers cage A-site cations that can be incorporated into their structures. It has recently been reported the Goldschmidt tolerance factor relaxed expanded in iodide 2D perovskites. Bromide perovskites, whose multilayer structures optical properties are much less stud...

The fixed points theorems for Rhoades-type contraction mapping were investigated by many authors [1, 5, 8, 10, 13, 16, 22] and the more results on this fields can be found in [2, 4, 9, 11, 15, 23]. Hybrid fixed point theory for nonlinear single-valued and multivalued maps is a new development in the domain of contraction-type multivalued theory (see [3, 7, 10, 12, 14, 17, 18, 20] and references...

Conflict Identification in Aspect-Oriented Requirements Engineering (AORE) is an integral step toward resolving conflicting dependencies between requirements at an early stage of the software development. However, to date there has been no work supporting detection of conflicts in a large set of textual requirements without converting texts into an alternative representation (such as models or ...
