Topology control in a wireless ad-hoc network allows better spatial reuse of the wireless channel and network resources. The existing topology control algorithms tend to optimise network power usage by keeping the topology connected but do not take the network application requirements into account. Mission critical applications which require explicit end-to-end bandwidth and delay guarantees ma...

This research intends to develop a method based on the Artificial Neural Network (ANN) to predict permanent earthquake-induced deformation of the earth dams and embankments. For this purpose, data sets of observations from 152 published case histories on the performance of the earth dams and embankments, during the past earthquakes, was used. In order to predict earthquake-induced deformation o...

Topology control is one of the most importance issues in performance optimization for wireless sensor network. It can prolong network lifetime, reducing radio interference, ensuring network connectivity and coverage. In this survey paper, we discuss the design object of topology control, study the different network topology models and graph models which used in topology control, typical topolog...

In this paper, a new embedded Z-H (EZ-H) buck-boost converter is proposed. In this topology, two identical dc voltage sources are embedded in a LC network in a series connection with the inductors. The proposed converter eliminates the shoot-through (ST) switching state and there is no need for a front-end diode. Other advantages of the proposed topology are having capability of buck and boost ...

The goal of topological design of a k-connected computer communication network is to achieve a specified performance at minimal cost/delay. Unfortunately, the problem is completely intractable. A reasonable approach is to generate a potential network topology. Stieglitz, Weiner and Kleitman have presented a heuristic for generating a potential network topology. This heuristic begins by numberin...

This paper presents a new structure to provide the ability for power sharing of two Z-source inverters. According to the operation principles of Z-source inverters, only one input source supplies the circuit, which is a limitation particularly for the stand alone systems feeded by limited output power such as photovoltaics and feul cells. Furthermore; if one source fails to supply,  the lo...

Cluster computing is becoming an accepted form of supercomputing in the academe, government and industries around the world. The Ateneo High Performance Computing Group (AHPCG) proposes a design for building a 192processor cluster using a symmetric and flat networking neighborhood. A routing schema will also be developed to maximize this network topology. This design aims to demonstrate this ne...
