In this article we give a short overview on sensitivity calculation using Monte-Carlo simulation and an introduction to the proxy simulation scheme method. We shortly discuss the localization technique and the implementation.

New bounds on the canonical angles between an invariant subspace of A and an approximating subspace by the differences between Ritz values and the targeted eigenvalues are obtained. From this result, various bounds are readily available to estimate how accurate the Ritz vectors computed from the approximating subspace may be, based on information on approximation accuracies in the Ritz values. ...

This paper uses a case example to review the current legal status of advance directives, as well as their ethical rationale. We draw attention to ongoing efforts to institutionalize advance directives, and to some of the tractable and intractable reasons why advance directives are ineffective. We then introduce the concept of advance care planning, and argue that we should not assume that advan...

This paper presents some of the results of the simulation in the radiation section of an industrial boiler using an advanced mathematical model. Calculations are described for the flow, heat transfer, and chemical reaction processes occurring within a gas-fired cylindrical furnace. The calculation procedure is a two dimensional one in which the main hydrodynamic variables are the velocity and s...

analyzing the vortex-induced vibration of a slender marine structure withlength to diameter ratio up to 200 is the objective of this study. this slender is free to move in both in-line and cross flow directions and immersed completely in water. three different types of shear currents pass on it and cause to vibrate slender in different forms. nowadays, these vibrations are very important for de...

in this study, a hybrid intelligent model has been designed to predict groundwater inflow to a mine pit during its advance. novel hybrid method coupling artificial neural network (ann) with genetic algorithm (ga) called ann-ga, was utilised. ratios of pit depth to aquifer thickness, pit bottom radius to its top radius, inverse of pit advance time and the hydraulic head (hh) in the observation w...

The fluctuation of normal leakage current has a great influence on the fixed-threshold protector. To address this issue, paper proposes an adaptive protection method based sparrow search algorithm (SSA)-backpropagation (BP) neural network. Based analysis generation mechanism, uses SSA optimized BP network to construct prediction model current. By dividing range into several intervals and settin...

It has been established that a biological neuron reproduces the precise spike response to identical fluctuating input currents. We wish to predict the firing times of a given neuron for any input current. For this purpose, a mathematical model is introduced for mimicking the voltage response of the neuron to an input current. In predicting the firing times of a target neuron for a novel input c...
