background: cardiac output (co) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. co is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. hence, measuring co has always been a matter of interest to researchers and clinicians. sev...

We describe a timing analysis algorithm which can achieve the efficiency of RC tree analysis while retaining much of the generality of Asymptotic Waveform Estimation. RC tree analysis from switch level simulation is generalized to handle piecewise linear transistor models, non tree topologies, floating capacitors, and feedback. For simple switch level models the complexity is O(n). The algorith...

Analysis of coded communications and electronic patient record data present a unique opportunity for nursing knowledge discovery, the integration of communication content with clinical data. However, joint analysis of coded communications and clinical data depends on the ability to link waveform audio files with patient records. A procedure has been developed to link waveform audio files with T...

In this paper we propose a suitable reference wave for Pulse Width Modulation (PWM) AC Drives. Staircase reference waves whose levels are calculated to eliminate certain harmonics are studied and a certain staircase reference waveform with L levels is constructed. When L is made very large in limit, this staircase waveform approaches a continuous one which is called Quasine (Quasi + Sine). This...

Estimation of the source of voiced speech, the glottal volume velocity waveform, with inverse filtering involves usually a parameterisation stage, where the obtained flow waveforms are expressed in numerical forms. This stage of the voice source analysis, the parameterisation of the glottal flow, is discussed in the present paper. The paper aims to give a review on the different methods develop...

INTRODUCTION The updated intrapartum cardiotocography (CTG) classification system by FIGO in 2015 (FIGO2015) and the FIGO2015-approached classification by the Swedish Society of Obstetricians and Gynecologist in 2017 (SSOG2017) are not harmonized with the fetal ECG ST analysis (STAN) algorithm from 2007 (STAN2007). The study aimed to reveal homogeneity and agreement between the systems in class...

We consider reeection of a pulse in a random medium with a strong reeector. We show that the wavefront of the reeected wave observed in the frame moving with the random propagation speed stabilizes to the deterministic waveform. The problem is studied using invariant imbedding. The results of numerical experiments illustrating the theory are presented.

The Static Var Compensator (SVC) and the Static Synchronous Compensator (STATCOM), as two components of Flexible AC Transmission System (FACTS) devices, play an important role in controlling the reactive power flow to the power network. Because of economic considerations, identifying the best location for installing the SVC and STATCOM is also important. The FACTS devices placement problem is c...

This approach to clustering stresses the use of multivariate plots that allow the user, for example, to "fly through hyperspace," observing his data. In addition, multivariate histograms, scatter plots, link -node plots, waveform plots, and others can be dynamically controlled from the console to provide a unique visual insight into data structure, which cannot be obtained from conventional off...
