Cardiac output measurement with pulse contour analysis is a continuous, mini-invasive, operator-independent, widely used, and cost-effective technique, which could be helpful to assess changes in cardiac output. The 4-quadrant plot and the polar plot have been described to compare the changes between 2 measurements performed under different conditions, and the direction of change by using diffe...
We present a set of visualization methods for the analysis of multivariate data recorded from the measurement of the performance of athletes during training. We use a modified training device to measure the force, acceleration, displacement, and speed of the athlete’s feet and arms while performing a certain training exercise. We are interested in visually measuring and comparing the performanc...
In this paper are presented the current results of scientific research of heart rate variability (HRV) analysis based on digital electrocardiograms (ECG). This analysis is a non-invasive and effective technique to reflect the autonomic nervous system regulation of the heart. HRV is used to diagnose and estimate of alterations in heart rate by measuring the variation of RR intervals (time interv...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
In this paper a robust approach for fitting multiplicative models is presented. Focus is on the factor analysis model, where we will estimate factor loadings and scores by a robust alternating regression algorithm. The approach is highly robust, and also works well when there are more variables than observations. The technique yields a robust biplot, depicting the interaction structure between ...
We present PLTplot, a plotting package for PLT Scheme. PLTplot provides a basic interface for producing common types of plots such as line and vector field plots from Scheme functions and data, an advanced interface for producing customized plot types, and support for standard curve fitting. It incorporates renderer constructors, transformers from data to its graphical representation, as values...
An interactive, audio-visual composition based on the universal wave equation and additive synthesis is presented. Visualization, sonification, and motion-capture interfaces are discussed in relation to their use within the piece. The technique of “density plot synthesis” is introduced to describe the technique of controlling sound-source amplitude levels through the wave equation or similar
