Normal left ventricular systolic time intervals assessed by pulsed wave Doppler echocardiography in the Turkmen horse of Iran
The Turkmen horse is one of the oldest and purest breeds in the world. There is no information with regards to the normal echocardiographic parameters of this horse regarding to cardiac diseases. Pulsed-wave (PW) Doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing Turkmen horses. There were 26 stallions and 16 mares. The left ventricular isovolumetric contrac...
متن کاملReal-time Scheduling of a Flexible Manufacturing System using a Two-phase Machine Learning Algorithm
The static and analytic scheduling approach is very difficult to follow and is not always applicable in real-time. Most of the scheduling algorithms are designed to be established in offline environment. However, we are challenged with three characteristics in real cases: First, problem data of jobs are not known in advance. Second, most of the shop’s parameters tend to be stochastic. Third, th...
متن کاملA Real-Time Four-Dimensional Doppler Dealiasing Scheme
A new dealiasing scheme uses the full four-dimensionality available in an operational Doppler radar data stream. It examines one tilt angle at a time, beginning at the highest elevation where clutter is minimal and gate-to-gate shear is typically low compared to the Nyquist velocity. It then dealiases each tilt in descending order until the entire radial velocity volume is corrected. In each ti...
متن کاملNormal pulsed wave Doppler echocardiographic parameters of Turkmen horses of Iran
Turkmen horse is one of the oldest and purest breeds in the world, but there is no information on Doppler echocardiographic parameters in this horse. In the present study, pulsed-wave (PW) Doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing Turkmen horses. No cardiac disease was detected with two-dimensional (2-D) real-time, M-mode, and colour flow mapping. D...
