Comparing Methods for Parameter Estimation of the Gompertz Tumor Growth Model

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Comparing The ANN And Linear Regression In Estimation Of The Growth Model (The Case Of MENA)

Estimation of the Domain of Attraction of Free Tumor Equilibrium Point for Perturbed Tumor Immunotherapy Model

In this paper, we are going to estimate the domain of attraction of tumor-free equilibrium points in a perturbed cancer tumor model describing the tumor-immune system competition dynamics. The proposed method is based on an optimization problem solution for a chosen Lyapunov function that can be casted in terms of Linear Matrix Inequalities constraint and Taylor expansion of nonlinear terms. We...

Comparing parameter estimation methods for service-based diffusion models

This paper compares methods for parameter estimation of diffusion models when seeking to extend these to service industry contexts from the traditional product focus. In the marketing science and economics literature, parameter estimation is dominated by econometric methods. This presents certain limitations as well as advantages compared to calibration in system dynamics modelling, which empha...
