This research examined the spatiotemporal patterns of land-use/cover and the dynamics of ecological capacity in response to land-use/cover change in Wuhan city, central China. The data were derived from five years' remote-sensed images, that is, 1990, 1995, 2000, 2005, and 2010. This paper used an integrated approach of remote sensing and GIS techniques, ecological capacity and the bilateral dy...

This paper extends the generalized Hamiltonian method (GHM) (Zhang et al., 2009; Zhang and Wong, 2010) and its half-size variant (HGHM) (Zhang and Wong, 2010) to their -parameter counterparts (called S-GHM and S-HGHM, respectively), for testing the passivity of -parameter descriptor-form models widely used in high-speed circuit and electromagnetic simulations. The proposed methods are capable o...

This paper extends the generalized Hamiltonian method (GHM) [1], [2] and its half-size variant (HGHM) [2] to their S-parameter counterparts (called S-GHM and S-HGHM, respectively), for testing the passivity of S-parameter descriptorform models widely used in high-speed circuit and electromagnetic simulations. The proposed methods are capable of accurately detecting the possible nonpassive regio...

Abstract. We study two-parameter bifurcation diagrams of the generalized Hénon map (GHM), that is known to describe dynamics of iterated maps near homoclinic and heteroclinic tangencies. We prove the nondegeneracy of codim 2 bifurcations of fixed points of GHM analytically and compute its various global and local bifurcation curves numerically. Special attention is given to the interpretation o...

of thesis entitled Passivity Assessment and Model Order Reduction for Linear Time-Invariant Descriptor Systems in VLSI Circuit Simulation Submitted by Zheng ZHANG for the degree of Master of Philosophy at the University of Hong Kong in June 2010 This thesis presents some theoretical and numerical results for linear time-invariant (LTI) descriptor systems (DSs), with emphasis on their correspond...

In this paper, we propose the application of the general homotopy method (GHM) to obtain rational solutions of nonlinear differential equations. It delivers a high precision representation of the nonlinear differential equation using a few linear algebraic terms. In order to assess the benefits of this proposal, three nonlinear problems are solved and compared against other semi-analytic method...

Introduction In France, GHM (French DRGs) have been used to fund the acute hospital sector since 2005, with extra per day for outliers or intensive care units, and specific payments for educational tasks, research and general interest. However, at present fees differ between for-profit and non-profit hospitals. But the law requires that fees must converge by 2012, with a 50% reduction in the di...

In today’s technology world, Virtual personal assistants (VPA) have become very common and most people started making their homes smart using these VPAs. Although different companies assistants, Google Home Mini (GHM) will be our focus in this paper. The first device, Home, was released November 2016 then GHM after a year, October 2017. has many features such as playing music, setting reminders...

Studies of intra-species cardiac fiber variability tend to focus on first-order measures such as local fiber orientation. Recent work has shown that myofibers bundle locally into a particular type of minimal surface, the generalized helicoid model (GHM), which is described by three biologically meaningful curvature parameters. In order to allow intra-species comparisons, a typical strategy is t...
