conclusions laparoscopic tapp inguinal hernia repair has longer operation time and more cost than the open technique. local wound complications were more prevalent in the open repair. the postoperative pain, the hospital stay, the scrotal-related complications as well as the recurrence rates were the same in the both groups. the laparoscopy can detect and treat other intra-abdominal pathologies...

Stress-intensity factors (SIFs) are the most important parameters in fracture mechanics analysis of structures. These parameters are evaluated for a stationary crack in functionally graded plates of arbitrary geometry using a novel Galerkin based mesh-free method. The method involves an element-free Galerkin method (EFGM), where the material properties are smooth functions of spatial coordinate...

A method that computes linear digital filter networks containing delay-free loops is proposed. Compared to existing techniques the proposed method does not require a rearrangement of the network structure, conversely it makes use of matrices describing this structure and specifying the connections between the filter blocks forming the network. For this reason the efficiency of the method become...

The stability and accuracy of three methods which enforce either a divergence-free velocity field, density invariance, or their combination are tested here through the standard Taylor?Green and spin-down vortex problems. While various approaches to incompressible SPH (ISPH) have been proposed in the past decade, the present paper is restricted to the projection method for the pressure and veloc...

This paper presents a hybrid algorithm on P/G networks of Mesh+Tree topology for ASICs. Based on existing algorithms, equivalent circuit method and TLM-ADI method, our algorithm is of linear complexity to solve P/G networks of Mesh+Tree topology. First, it uses equivalent circuit approach to compress the Mesh+Tree P/G circuit into the circuit only of Mesh topology, which is a linear complexity ...

In this paper, we propose a novel mesh-free numerical method for solving the elliptic interface problems based on deep learning. We approximate solution by neural networks and, since may change dramatically across interface, employ different each sub-domain. By reformulating problem as least-squares problem, discretize objective function using mean squared error via sampling and solve proposed ...
