Parameter Identification in a Two-Dimensional Parabolic Equation Using an ADI Based Solver

Abstract: In this work we consider the identification of spatially varying diffusivity in the diffusion-convection-reaction equation from point observations of the state variable. A least-squares approach is used for the parameter identification problem. In order to overcome the ill-posedness for identifying the spatially dependent parameter, the cost functional associated to identification problem is regularized. We studied both the effect of the regularization parameter and the effect of the level of discretization on the parameter estimates. The alternating direction implicit (ADI) method is considered for solving the linear systems of equations. The results of some numerical experiments are presented.

Perineal canal: a special entity of anorectal malformations in Vietnam

Abstract: We report our clinical experience with the perineal canal and suggest the management. Retrospective chart review of patients with perineal canal were classified by lesion characteristics into Group I: active perineal inflammation, Group II: vulvar excoriation and Group III: no active inflammation. Group III patients underwent primary surgical repair. Group I and II patients underwent repair after medical management. The fistula was repaired by the modified Tsuchida’s technique consisting of an anterior anopullthrough and excision of the fistula tract (reverse order). Between September 1999 and August 2003, we treated 120 cases of perineal canal. Group I, II and III consisted of 74, 12 and 34 patients, respectively. In two patients of Group I (2.7%), the fistula tract spontaneously closed. The remaining 118 patients were surgically treated with the modified Tsuchida’s technique. Recurrences were similar between patients treated with colostomy (1/28 or 3.6%) versus without colostomy (3/90 or 3.0%), as well as between patients initially treated with primary repair (3/102 or 2.9%) versus patients undergoing reoperation with redo repair (1/16 or 6.25%). With proper initial medical treatment, the perineal canal could be repaired successfully in one stage with the modified Tsuchida’s technique.

Virtual Modeling and Numerical Simulations of the Latitude Prosthesis - Human Elbow Assembly

Abstract: The Latitude Prosthesis is a complex implant for human elbow joint with a great constructional flexibility, providing the possibility, depending on the intraoperative situation and the residual instability, to “move” intra-operatively from a non-constrained prosthesis to a constrained prosthesis by a piece attached to the component ulnar. This study aims to present the virtual modeling of the Latitude elbow prosthesis and of the human elbow joint-Latitude prosthesis assembly. The kinematic simulation of the flexion-extension and pronation-supination movements of the elbow joint-Latitude prosthesis–assembly are performed.

Study of the Expansion Behaviour of Some Materials Used in the Dental Metal-Ceramic Technology

Abstract: In this paper we have focused on the study of the thermal expansion coefficient of a dental alloy, WBC, and its compatibility with a ceramic mass ,VITA VM 13, following thermal treatment according to the technological stages of production of a metal-ceramic prosthetic restoration.
