the conceptualization of resilience as a general or multidimensional construct and recognizing the inhibitors and facilitators of it are the main issues in the resilience literature. therefore, the present study investigated the discriminant variables of educational resilient and emotional resilient groups in person-focused approach, to examine the general or multidimensional construct of resil...

The objective of this paper is to propose an approach to decentralized resilient networked robustly exponentially stabilizing with H∞-norm bound γ observerbased controller for a class of uncertain symmetric composite continuous-time systems with nonlinearities. Such systems are composed of identical nominal subsystems, symmetric nominal interconnections, norm-bounded parameter uncertainties, an...

Big cities in developing countries face many obstacles related to the built environment when confronted by socioeconomic inequalities, which is reflected uneven access basic living infrastructure, such as sanitation and housing. In light of new approaches traditional materials building techniques, this article aims investigate use digital fabrication tools production lightweight precast systems...

The problem of observer design for nonlinear systems has got great attention in the recent literature. The nonlinear observer has been a topic of interest in control theory. In this research, a modified robust sliding-mode observer (SMO) is designed to accurately estimate the state variables of nonlinear systems in the presence of disturbances and model uncertainties. The observer has a simple ...

this paper presents a new observer design methodology for a time varying actuator fault estimation. a new linear matrix inequality (lmi) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (fafe). the fafe is capable of estimating a wide range of time-varying actuator fault...

In this paper, we propose a new chaos-based communication scheme using the observers. The novelty lies in the masking procedure that is employed to hide the confidential information using the chaotic oscillator. We use a combination of the addition and inclusion methods to mask the information. The performance of two observers, the proportional observer (P-observer) and the proportional integra...

a resilient soft liner (rsl) has been used in processed complete dentures but controlling its thickness has always been a challenge because of uneven reduction of the denture's intaglio surface. use of a thermoplastic vacuum-formed template and an endodontic k-file, as guides, for the reduction of a processed mandibular complete denture to receive rsl is described in the present report. a proce...

This paper investigates the coincidence between six interest point detection methods (SIFT, MSER, Harris-Laplace, SURF, FAST & Kadir-Brady Saliency) with two robust “bottom-up” models of visual saliency (Itti and Harel) as well as “task” salient surfaces derived from observer eye-tracking data. Comprehensive statistics for all detectors vs. saliency models are presented in the presence and abse...
