The demand of reliable statistics for small areas, when only reduced sizes of the samples are available, has promoted the development of small area estimation methods. In particular, an approach that is now widely used is based on linear mixed models. Chambers & Tzavidis (2006) have recently proposed an approach for small area estimation that is based on M-quantile models. However, when the fun...

Many applications that aim at enhancing sustainability rely on some sort of spatio-temporal model. The task can be monitoring or prediction in traffic networks, power grids, building energy management, river flow volume, and sea level – to mention just a few. The positive effect on the environment is achieved by a better control, better planning of processes or better disaster management. Spati...

The sensitivity of asset fixity conclusions, input adjustment rates, and elasticities to choice of functional form is examined using a dynamic dual model of U.S. agriculture. A very general initial specification allows tests of instantaneous adjustment to be performed for every input. Test results are mixed across functional forms for all inputs except real estate, which is consistently found t...

This article presents an effective computational approach that incorporates a quasi-brittle damage model into the isogeometric analysis of plates made functionally graded materials. The plate kinematics is represented by third-order shear deformation theory for higher accuracy. A coupling nonlocal equivalent strain field introduced on neutral surface to control softening behavior. utilization i...

Abstract Due to the conflict between equilibrium and constitutive requirements, Eringen’s strain-driven nonlocal integral model is not applicable nanostructures of engineering interest. As an alternative, stress-driven has been recently developed. In this paper, for higher-order shear deformation beams, ill-posed issue (i.e., excessive mandatory boundary conditions (BCs) cannot be met simultane...

Abstract In this work, the bending behavior of nanoplates subjected to both sinusoidal and uniform loads in hygrothermal environment is investigated. The present plate theory based on classical laminated thin with strain gradient effect take into account nonlocality nanostructures. equilibrium equations have been carried out by using principle virtual works a system partial differential sixth o...

We study a discrete host-parasitoid system where the host population follows the classical Ricker functional form and is also subject to Allee effects. We determine basins of attraction of the local attractors of the single population model when the host intrinsic growth rate is not large. In this situation, existence and local stability of the interior steady states for the host-parasitoid int...
