Parameter identification of rock mass in the time domain

Scientific Reports
A time domain rock mass parameter identification method considering the Rayleigh damping is proposed in this paper. Starting with a set of initial parameter values, the algorithm solves the finite-element (FE) equations updating the parameters in each ...

Multiple-Input Multiple-Output Microwave Tomographic Imaging for Distributed Photonic Radar Network

Remote Sensing
This paper deals with the imaging problem from data collected by means of a microwave photonics-based distributed radar network. The radar network is leveraged on a centralized architecture, which is composed of one central unit (CU) and two transmitting

Estimating multilevel models for categorical data via generalized least squares

Revista Colombiana de Estadística, 2005
Montero et al. (2002) proposed a strategy to formulate multilevel models related to a contingency table sample. This methodology is based on the application of the general linear model to hierarchical categorical data. In this paper we applied the method
