OBJECTIVE Pulse contour analysis can be used to provide beat-to-beat cardiac output (CO) measurement. The current study sought to evaluate this technique by comparing its results with lithium dilution CO (LiCO) measurements. DESIGN Prospective, observational study. SETTING Surgical intensive care unit. PATIENTS Twenty-two patients after cardiac or major noncardiac surgery. MEASUREMENTS ...

Microarray technology is a powerful tool that allows scientists to study expression levels for thousands of genes simultaneously. The technology has been useful in many applications, e.g., disease diagnosis, drug discovery, and gene functional study. In this paper, we present a microarray image analysis system which works specifically on nylon membrane microarray. These membrane microarray imag...

The article presents the applicability of 3D printing in casting. Even complex models produced by can be effectively applied field lost pattern process was realized using Polycast and Pioneer investment powder (gypsum). Based on measurement it is clear that size differences come from technology. minimum wall thickness cannot less than 0.8 mm, but there inaccuracy under 2.1 mm when no infill sec...

We present an approach for modeling and filtering digitally scanned images. The digital contour of an image is segmented to identify the linear segments, the nonlinear segments and critical corners. The nonlinear segments are modeled by B-splines. To remove the contour noise, we propose a weighted least q m s model to account for both the fitness of the splines as well as their approximate cur...
