CARDIOVASCULAR MEDICINE ECGSIM: an interactive tool for studying the genesis of QRST waveforms

ECGSIM: an interactive tool for studying the genesis of QRST waveforms.

BACKGROUND Discussion about the selection of diagnostic features of the ECG and their possible interpretation would benefit from a model of the genesis of these signals that has a sound basis in electrophysiology as well as in physics. Recent advances in computer technology have made it possible to build a simulation package whereby the genesis of ECG signals can be studied interactively. DES...

Endothelial Progenitor Cell Dysfunction in Polycystic Ovary Syndrome: Implications for The Genesis of Cardiovascular Diseases

Modeling the Circle of Willis Using Electrical Analogy Method under both Normal and Pathological Circumstances

Background and objective: The circle of Willis (COW) supports adequate blood supply to the brain. The cardiovascular system, in the current study, is modeled using an equivalent electronic system focusing on the COW.Method: In our previous study we used 42 compartments to model whole car- diovascular system. In the current study, nevertheless, we extended our model by using 63 compartments to m...

An Intelligent Method Based on WNN for Estimating Voltage Harmonic Waveforms of Non-monitored Sensitive Loads in Distribution Network

An intelligent method based on wavelet neural network (WNN) is presented in this study to estimate voltage harmonic distortion waveforms at a non-monitored sensitive load. Voltage harmonics are considered as the main type of waveform distortion in the power quality approach. To detect and analyze voltage harmonics, it is not economical to install power quality monitors (PQMs) at all buses. The ...

THE DESIGN, MODELING AND EVALUATION OF POTENTIAL HIV PROTEASE INHIBITORS USING BLITZ, AN INTERACTIVE COMPUTER GRAPHICS WORKING TOOL

Several nonpeptide small molecules were designed as potential inhibitors of HIV protease and their structures were constructed by computer-aided molecular modeling and docked iwo the active site of HIV protease. Models of the complexes of inhibitors and the HIV protease were refined using nonbonded and H-bonding terms. The refined energy of selected complexes showed that the designed inhib...
