BACKGROUND Blood pressure (BP) monitoring with arterial waveform display requires an arterial cannula. We evaluated a new noninvasive device, Vasotrac (Medwave, Arden Hills, MN) that provides BP measurements approximately every 12-15 beats and displays pulse rate and a calibrated arterial waveform for each BP measurement. METHODS Surgical and critically(More)
PURPOSE To evaluate the accuracy of a new non-invasive method (Vasotrac) to measure blood pressure (BP) with accompanying arterial wave-form and pulse-rate display when compared with BP and waveform measured invasively. METHODS Healthy volunteers (n=53) served as subjects for the study. Blood pressures and waveforms obtained via a radial artery catheter(More)
AGNESS is an expert system shell developed at the University of Minnesota. AGNESS is more general than other shells. It uses a computation network to represent expert defined rules, and can handle any well-defined inference method. The system works with non-numeric as well as numeric data, and shares constructs whenever possible to achieve increased storage(More)
We describe the design principles and functionality of a visual query language called SeeQL that represents data retrieval and analysis operations as a data-ow graph. A query is viewed as a sequence of re-lational algebra and other data transformation operations applied to database tables. The language is well-suited for large-scale scientiic database(More)
Summary form only given. The authors have applied a simple back propagation neural network on a very large scale in an attempt to associate many primary sequences with representations of the corresponding three-dimensional structures. The training set consisted of 25 five sequences (the input layer, 130 amino acids long) associated with 25 130*130 distance(More)
