Interface boundary conditions are the key ingredient to design efficient domain decomposition methods. However, convergence cannot be obtained for any method in a number of iterations less than the number of subdomains minus one in the case of a one-way splitting. This optimal convergence can be obtained with generalized Robin type boundary conditions associated with an operator equal to the Sc...

in this study 121 prescapular, prefemoral and popliteal lymph node of male healthy camel from mashhad abattoir were collected. after collecting of specimens factors such as: length, width, thickness, weight, volume and density of each lymph node were measured by caliper device. all factors were analyzed and compared using excel program. it was revealed that, normal dimensions of right prescapul...

The use of the boundary element method (BEM) is explored as an alternative to the finite element method (FEM) solution methodology for the elliptic equations used to model the generation and transport of fluorescent light in highly scattering media, without the need for an internal volume mesh. The method is appropriate for domains where it is reasonable to assume the fluorescent properties are...

This paper considers Schrödinger operators, and presents a probabilistic interpretation of the variation (or shape derivative) of the Dirichlet groundstate energy when the associated domain is perturbed. This interpretation relies on the distribution on the boundary of a stopped random process with Feynman-Kac weights. Practical computations require in addition the explicit approximation of the...

We believe that it is not a trivial job to maintain and manage clusters in a highly mobile ad hoc scenario where host mobility and changes in node activity status causes frequent and unpredictable topological changes. It requires continuous and efficient management protocol for frequent up-dation and re-clustering which are costly in a resource-poor environment. This maintenance process may eve...

In this work, we investigate the stability region, the throughput performance, and the queueing delay of an asymmetric relay-assisted cooperative random access wireless network with multipacket reception (MPR) capabilities. We consider a network of N saturated source users that transmit packets to a common destination node with the cooperation of two relay nodes. The relays are equipped with in...

This paper discusses the implementation of a numerical method for simulating petroleum reservoirs, based on finite volume technique using non-structured grids, designed for parallel computing platforms with distributed-memory, particularly for clusters of workstations. Non-structured meshes are used in order to enhance the capability of conforming the irregular boundary of the reservoir allowin...

The Internet of Things (IoT), which combines identification, sensing, computing and communication technologies, is considered one of the major trends in information and communication technologies. Communication performance is critical for IoT applications. According to previous research, an internet-based overlay model is feasible for the implementation of the IoT. One important issue in the ov...

In this paper, we propose a coverage measurement protocol (CMP) which can provide the base station an accurate and in-time measurement of the current connected coverage in an energy-efficient way, and our CMP is location-error tolerant. Moreover, the major component of our CMP, i.e., BOundary Node Detection (BOND) scheme, can be reused to provide many other functionalities for WSNs.

In this study, a cellular automaton (CA) is developed o combine the advantages of finite element method (FEM) and meshless method to analyze two-dimensional elastic problems. By the CA, a two-dimensional domain is discretized into a grid of nodes which are distributed randomly in the domain. For convenience, the nodes are classified into the FEM group and the meshless group. In the FEM zone tha...
