Current methods of oil and gas field development design rely on reservoir simulation modeling. A model is a tool to reproduce processes forecast production data. Reservoir permeability one the basic properties that determines fluid flow. From existing approaches, porosity values should be consistent with petrophysical correlations obtained from core sample tests in course an absolute cube model...

Off-grid settlements require efficient, reliable and cost-effective renewable energy as alternative to the power supplied by diesel generator. Techno-economic analysis is required to find the optimum renewable energy system in the long run. This paper reviews the application of genetic algorithms in optimization of hybrid system consisting of pico hydro system, solar photovoltaic modules, diese...

In this paper, we address the high SNR regime of the MIMO broadcast channel under linear filtering. For systems where the base station is equipped with more antennas than the user terminals have in sum, we prove that block-diagonalization is the asymptotically optimum transmission strategy for maximizing the sum rate. For this type of transmission strategy, the asymptotically optimum transmit c...

A new adaptive hybrid optimization strategy, entitled squads, is proposed for complex inverse analysis of computationally intensive physics-based models. Typically, models are calibrated and model parameters are estimated by minimization of the discrepancy between model simulations characterizing the system and existing observations requiring a substantial number of model evaluations. Squads is...

In this paper, an Alamouti-coded decode-and-forward protocol with optimum relay selection for three-user one destination cooperative communications is investigated. Particularly, we design the new protocol that allows the source node retransmitting the signal to the destination node at the same time as the relay node forwarding the received signal to the destination node with an Alamouti coding...

Evolutionary games are studied where the teaching activity of players can evolve in time. Initially all players following either the cooperative or defecting strategy are distributed on a square lattice. The rate of strategy adoption is determined by the payoff difference and a teaching activity characterizing the donor’s capability to enforce its strategy on the opponent. Each successful strat...
