introduction: content based image retrieval (cbir) is a method of image searching and retrieval in a  database. in medical applications, cbir is a tool used by physicians to compare the previous and current  medical images associated with patients pathological conditions. as the volume of pictorial information  stored in medical image databases is in progress, efficient image indexing and retri...

the aim of the present study was to investigate the physicochemical performances at three sites on skin, namely the diagonal, neck and leg based on different age groups. eighteen skins pieces in 6 m, 6 m to 1 yr and 1 yr to 1.5 yr of age were selected to represent means of the respective age groups with regard to skin area. the skin area were7.4±1.41, 13.5±1.4 and 18.2±1.1 ft2 for the ostriches...

Finding the best weights of the state variables and the control variables in the objective function of a linear-quadratic control problem is considered. The weights of these variables are considered as two diagonal matrices with appropriate size and so the objective function of the control problem becomes a function of the diagonal elements of these matrices. The optimization problem which is d...

We study an extension of the gravity dual to a perfect fluid model found by Janik and Peschanski. By relaxing one of the constraints, namely invariance under reflection in the longitudinal direction, we introduce a metric ansatz which includes off-diagonal terms. We also include an R-charge following Bak and Janik. We solve the Maxwell-Einstein equations and through holographic renormalization,...

A Neutron Transport Code ATES3 (Anisotropic Transport Equation Solver in 3D), which was developed at BARC for the deterministic solution of 3D steady-state neutron transport problems, has been parallelized using Message Passing Parallel Programming model on BARC’s ANUPAM Parallel Supercomputer. The most time consuming step in the code ATES3, which is transport sweep, was made parallel using thr...

We introduce some numerical approximations to a quasilinear problem, proposed by G. I. Barenblatt to describe non-equilibrium two-phase fluid flow in permeable porous media, with the application to the secondary oil recovery from natural reservoirs. Taking into account the theoretical results of global existence and uniqueness, approximated solutions are computed by three numerical schemes, nam...

A sufficient condition for global synchronization in coupled map lattices (CML) with translation invariant coupling and arbitrary individual map is proved. As in [Jost & Joy, 2001] where CML with reflection invariant couplings are considered, the condition only involves the linearized dynamics in the diagonal, namely for all points in the diagonal, the derivative must be contractive in all tran...

A discrete-time population model in which individuals are distributed over a discrete phenotypic trait-space is studied. It is shown that, for an irreducible mutation matrix , if mutation is small, then an interior equilibrium exists, that is globally asymptotically stable in , while for arbitrary large mutation each trait persists uniformly. For the model reduced to only two traits, conditions...
