Monte Carlo methods for estimating linear combinations of inverse matrix entries in lattice QCD
The lattice formulation of quantum chromodynamics (QCD) uses very large matrices (≈ 106×106 or larger). Certain linear combinations of inverse matrix elements have physical interest. Unfortunately,Expand

Mathematical Modelling and Optimal Control of Anthracnose
In this paper we propose two nonlinear models for the control of anthracnose disease. The first one is an ordinary differential equation (ODE) model which represents the whithin host evolution of theExpand

Pade - Z(2) estimator of determinants
We introduce the Pade-Z2 (PZ) stochastic estimator for calculating determinants and determinant ratios. The estimator is applied to the calculation of fermion determi- nants from the two ends of theExpand

Optimal control of anthracnose using mixed strategies.
In this paper we propose and study a spatial diffusion model for the control of anthracnose disease in a bounded domain. The model is a generalization of the one previously developed in [15]. We useExpand

Efficient scalable sensor node placement algorithm for fixed target coverage applications of wireless sensor networks
TLDR
This paper proposes and implements a stochastic physics-based optimisation algorithm that is both efficient (guarantees full target coverage with a reduced number of sensors) and scalable (meaning that it can be executed for very large-scale problems in a reasonable computation time). Expand

Improvements on Secant Method for Estimating Internal Rate of Return (IRR)
Various capital budgeting methods are used by firms to decide which projects to undertake. One of the most common methods is the Internal Rate of Return (IRR) method. IRR does not have aExpand

TLDR
The problem of optimal beamforming for two-way relay (TWR) systems with perfect channel state information (CSI) is reduced to a pair of algebraic equations in two variables that can be solved very inexpensively using the conjugate gradient algorithm. Expand

A SIGNAL-PROCESSING INTERPRETATION OF QUANTUM MECHANICS
We present a new model to explain the behavior of transmitted quantum particles, by analogy with a wireless communication system. The particle’s complex wavefunction is interpreted as the amplitudeExpand
