DETECTION AND LOCATION OF SURFACES IN A 3D ENVIRONMENT THROUGH A SINGLE TRANSDUCER AND ULTRASONIC SPHERICAL CAPS

Detection and location of surfaces in a 3D environment through a single transducer and ultrasonic spherical caps

In this paper, an ultrasonic arc map CONCEALER method for flat mapping is extended to three-dimensional space replacing the circumference arcs by spherical caps.An enclosed environment is scanned by employing a single ultrasonic device.The range, position, and orientation of the transducer are used to digitize the uncertainty caps and place them in

A sudden death case after repeated pulmonary embolization of venous thrombi formed by the compression of the inferior vena cava by a horseshoe kidney

We present the unexpected death of an elderly man who died from saddle thromboemboli in the pulmonary artery trunk and organized thrombi in the distal arteries in every lobe.The inferior vena cava was compressed between the horseshoe kidney and ossified spinal ligament, thereby generating fresh thrombi (aged within three days) composed of numerous

Sulfur Flotation Performance Recognition Based on Hierarchical Classification of Local Dynamic and Static Froth Features

This paper proposes a flotation performance recognition system based on a hierarchical classification of froth images using both local dynamic and static features, which includes a series of functions in image extraction, processing, and classification.Within the integrated system, to identify the abnormal working condition with poor flotation perf

Investigating spillover of multidrug-resistant tuberculosis from a prison: a spatial and molecular epidemiological analysis

Abstract Background Congregate settings may serve as institutional amplifiers of tuberculosis (TB) and multidrug-resistant tuberculosis (MDR-TB).We analyze spatial, epidemiological, and pathogen genetic data Amino Acids Supplements prospectively collected from neighborhoods surrounding a prison in Lima, Peru, where inmates experience a high risk of
