A novel color damaged index of digital images
2015 11th International Conference on Natural Computation (ICNC), 2015A novel color damage index of digital images is proposed based on the color characteristic histogram distance and primary and fundamental color distribution characters perceived by the human vision system. The proposed arithmetic measures the quality of an image which is damaged by the JPEG image compression scheme through comparing the cumulative ...

EVALUATION OF STRENGTH AND DAMAGE INDEXES FOR BUILDINGS
2006In order to evaluate and improve seismic capacity of existing buildings seismic safety evaluation and retrofitting are very important tasks. Engineers make these evaluations with different methods, from too simple to too sophisticated ones. The presented method combines experimental data and engineering knowledge for evaluation of the seismic safety ...

A new flexibility-based damage index for structural damage detection
Smart Materials and Structures, 2013A new flexibility-based damage index has been proposed for structural damage detection. It is derived from the strain energy theory that the ratio of the flexural stiffness of the structure before and after damage is a function of the uniform load surface (ULS) curvature.

Damage Detection Utilizing the Damage Index Method to a Benchmark Structure
Journal of Engineering Mechanics, 2004This paper addresses the first generation benchmark problem on structural health monitoring developed by the ASCE Task Group on Structural Health Monitoring. The focus of the problem is a four-story model of an existing physical model at the University of British Columbia where simulated data are used for the system identification.

Flexural damage index equations of a plate
Journal of Sound and Vibration, 2005A new nondestructive damage evaluation method is introduced. The method is able to detect, locate, and size structural damage in a plate-like structure using measured modal parameters of a structure. The solution procedure consists of two steps: First, the method requires constructing a set of flexural damage index equations that represent a rigorous ...

[Prognostic index of acute hepato-cellular damage].
Annali italiani di chirurgia, 2007Fulminant hepatic failure is the end result of many different acute damage to the liver. In the present study we compared the clinical to the experimental experience and we postulated the usage of Vascular Endothelial Growth Factor in the clinical arena as a potential treatment in alternative to liver transplantation.Twelve patient diagnosed with ...

Methods for Improving the Damage Recognition Ability of Curvature Damage Index
International Journal of Structural Stability and DynamicsThe curvature damage index (CDI) has gained broad application in the fields of structural damage detection and localization due to its high damage sensitivity and accurate localization. However, this index exhibits significant limitations in weak-damage detection: When structural damage severity is low, damage-induced curvature perturbations are prone

Strength and Damage Indexes for Evaluation and Retrofit of Buildings
2007ABSTRACT: Strength and damage indexes of buildings are suggested as a method for evaluation of existing buildings for their ‘ seismic safety’ and ‘ retrofitting’ . The presented method is simple and combines experimental data and engineering knowledge.
