This paper is concerned with the detection and characterization of hidden defects in advanced structures before they grow to a critical size. A novel method is developed using a combination of vibration and wave propagation data to determine the location and degree of damage in structural components requiring minimal operator intervention. The structural component is to be instrumented with an ...

The presented research investigates the application of close-range photogrammetry surveying techniques and Augmented Reality (AR) visualization to design a semi-automated method for rapidly measuring structural damage induced in tall buildings by seismic events such as earthquakes or explosions. Close-range photogrammetry algorithms were designed to extract spatial information from photographic...

grounds, implying the presence of senile plaques and neurofibrillary tangles in the hippocampus and cerebral cortex. Brain autopsy studies indicate that these lesions are present in about 90% of patients clinically diagnosed by experienced physicians. The utility of biomarkers for enhancing diagnositic sensitivity for AD may consequently be relatively limited since clinical methods are generall...

Disease activity assessment is one of the most pivotal aspects in the care of RA patients. Composite measures of disease activity are superior to individual measures, since they capture the multiple facets of the disease. Since swollen joint counts correlate with joint damage progression and tender joint counts with physical function, composite scores that include joint counts are preferable. T...

BACKGROUND AND PURPOSE Selective white matter (WM) damage is a known sequela of mild hypoxic-ischemic (HI) injury in the neonatal rat model. The aim of this study was to evaluate longitudinally mild HI-induced WM damage (represented by the external capsule [EC]) by diffusion tensor MR imaging (DTI) and to correlate the findings with histology. MATERIALS AND METHODS Seven-day-old Sprague-Dawle...

This paper extends some authors’ previous approaches to models and methods based on fuzzy sets and fuzzy logic, for the seismic fragility updating and seismic damage evaluation, in their contributions to the IFIP 8 Conference (Krakow – 1998), SMiRT 16 (Washington DC – 2001) and SMiRT 18 (Beijing – 2005) Conferences. A short survey of such earlier and more recent proposals for applying fuzzy con...

PURPOSE To illustrate the potential role for Heidelberg edge perimetry (HEP) in the assessment of early functional loss in glaucoma. CASE REPORT A 46-year-old male presented with raised intraocular pressure but healthy optic discs and normal standard automated perimetry (SAP). He was diagnosed with ocular hypertension, but after 16 years, he developed glaucomatous changes to the right optic d...

This study presents numerical simulations and experimental verification of a vibration-based damage detection technique. Health monitoring of a submerged pipe's girth-weld against an advancing notch is attempted. Piezoelectric transducers are bonded on the pipe for sensing or actuation purposes. Vibration of the pipe is excited by two means: (i) an impulsive force; (ii) using one of the piezoel...

This study aimed to evaluate the long-term dietary effects of dried olive pulp (OP) on production performance, fatty acid profile and health lipid indices quality characteristics produced eggs, welfare indicators laying hens. It was carried out in a commercial poultry farm using 300 Isa Brown layers at 23 weeks age. The hens were randomly equally divided six groups CON, OP2, OP3, OP4, OP5 OP6, ...

The effect of increasing dietary intakes of polyunsaturated fatty acids (PUFAs) and vitamin E on indices of oxidative DNA damage was investigated. Twenty-one healthy male, nonsmokers aged 28.9 +/- 1.3 years participated in a free-living, split plot/change over trial in which half the volunteers consumed diets containing 5% PUFA as food energy for 4 wk and, after a 10 wk washout period, consumed...
