Method and Apparatus for Improved Active Sonar
The invention is a method for improved active sonar using a singular value decomposition filtering and a Volterra-Hermite Basis Expansion to model real active sonar measurements. The fitting model minimizes the sum of the squared errors between a measured channel response, z(t), and model response, y(t), which is a fitted Volterra Series solution. The model requires as input an excitation wavef...
متن کاملThe Danger of Aspirating the Liver
u drawing attention in the Indian Medical Gazette for April, 1898, to the possibility of aspiration of the liver producing a fatal haemorrhage into the cavity of the peritoneum. This important fact is but little known, and has been seldom referred to in writings on the treatment of liver abscess. Surgeon-Lt.-Colonel Hatch recommends caution in the operation of aspiration of the liver for diagno...
متن کاملImproved apparatus and procedures for isopiestic studies at elevated temperatures
A significantly improved apparatus for the isopiestic measurement of thermodynamic activities at elevated temperatures is described. Details of the new design and of an analysis of the propagation of the experimental errors are presented. The apparatus was tested by measurements of calcium chloride against sodium chloride at 353.15 K. Accuracies of better than 0.1% in the osmotic coefficient ar...
متن کاملAn improved apparatus for transscleral iontophoresis of gentamicin.
The authors previously found that positively charged substances are less well-transported into the vitreous humor by transscleral iontophoresis than are negatively charged substances. There was more bubble formation in the eye cup with positively charged than with negatively charged substances. The authors hypothesized that these bubbles might account for the poorer conductance of the positivel...
متن کاملAn Effective and Novel Design for Aspirating Sputum With
45 BACKGROUND: Conventional sputum suction is a routine clinical practice, but complications may 46 arise from the blind manipulation of the catheter. Recently, a visual sputum suction system (VSSS) was 47 developed. We hypothesized that this new system would be feasible and efficient for sputum suction in 48 a laboratory setting. 49 METHODS: We used 1.5% and 3.0% coagulant to simulate mucus an...
