Automatic writer identification and writer verification has recently received significant attention in the field of historical analysis. In this work a short overview of current approaches for writer identification is given. Current state-of-the-art results on contemporary data are related to different approaches for writer verification on a small dataset of datum lines extracted from papal cha...

The highly nonlinear responses of compliant ocean structures characterized by a large-geometry restoring force and a coupled fluid-structure interaction excitation are of great interest to ocean engineers. Practical modeling, parameter identification, and incorporation of the inherent nonlinear dynamics in the design of these systems are essential and challenging. An experimental mooring system...

We derive a cost functional for estimating the inverse of the observation function in nonlinear dynamical systems. Limiting our search to invertible observation functions confers numerous benefits, including a compact representation and no local minima. Our approximation algorithms for optimizing this cost functional are fast, and give diagnostic bounds on the quality of their solution. Our met...

this paper presents a method for identification of linear system physical parameters (structural mass, damping and stiffness matrices) using the inverse solution of equation of motion in the frequency domain, by focus on the reducing the illconditioning effect. the method utilizes the measured responses from the forced vibration test of structure in order to identify the system properties and d...

The aim of this paper is to investigate a novel approach for output feedback damping controller design ofSTATCOM in order to enhance the damping of power system low frequency oscillations (LFO). The design ofoutput feedback controller is considered as an optimization problem according with the time domain-basedobjective function which is solved by a honey bee mating optimization algorithm (HBMO...

In this paper, a new algorithm for system identification based on frequency response is presented. In this method, given a set of magnitudes and phases of the system transfer function in a set of discrete frequencies, a system of linear equations is derived which has a unique and exact solution for the coefficients of the transfer function provided that the data is noise-free and the degrees of...

Background & Aims of the Study: One of the main concerns of policymakers is the establishment of health equity and access to health services. Health system reform plan is one of the most important tools of policy makers in the health system. The health system, as any other plan has had some problems during implementation. Therefore, the purpose of this study is to identify the obstacles to the ...
