Introduction: Myocardial perfusion imaging using gated SPECT and phase analysis is an effective tool in evaluation of mechanical dyssynchrony. The purpose of this study was to determine the normal ranges of global and regional phase parameters. Methods: A total of 100 patients with normal resting and stress electrocardiograms, low pretest likelihood for c...

In every tunnel boring machine (TBM) tunneling project, there is an initial low production phase so-called the Learning Phase Period (LPP), in which low utilization is experienced and the operational parameters are adjusted to match the working conditions. LPP can be crucial in scheduling and evaluating the final project time and cost, especially for short tunnels for which it may constitute a ...

Looking to the future, evolutionary development can be expected because the separating power of multidimension liquid chromatography is greatly increased over single-dimension liquid chromatography. The simultaneous improvements on both the software and the chromatographic apparatus will lead to a system capable of automatically developing analytical methods for a wide range of analytes in many...

We focus on the random generation of SAT instances that have computational properties that are similar to real-world instances. It is known that industrial instances, even with a great number of variables, can be solved by a clever solver in a reasonable amount of time. This is not possible, in general, with classical randomly generated instances. We provide different generation models of SAT i...

A laser Doppler velocimetry bench adapted for measuring acoustic particle velocities is used to measure sinusoidal structural velocities in order to assess the performance of two signal processing techniques, one available commercially and the other being developed in our laboratory. Considering a sinusoidal excitation signal of the vibrating structure, both techniques use frequency demodulatio...

fab (french – american- british) group determined a diagnostic classification for leukemia's. but in spite of some reports on different clinical findings and prognosis of hmc and lgl there is no place for hand- mirror cell leukemia and lgl leukemia in this classification. on the other hand, there are different ideas about causes of hand mirror cell and about different changes of large granlar l...

> The motion and shape of a flattened drop and bubble through another continuous liquid phase (conveying phase) are investigated experimentally, using a narrow gap HeleShaw cell. Seven different liquid-liqu...
