A linear flow velocity of 5 cm/min was obtained using four on-board pumps in a closed loop of circumferential track length of 10 cm (channel cross section of 0.5 mm × 0.5 mm), whereas it dropped to 1.8 mm/min in a packed bed column operated by a single pump.
Otherwise, the aggregation process will run out of a circumferential track, and the tortile and incomplete circular ring structures will be formed (Fig. 2b).
With regard to target detection in high resolution panorama images attained by circumferential scan Infrared Search and Tracking system, a rough-to-meticulous real-time target detection algorithm is proposed based on analysis of characteristics of targets and background.

Speckle tracking strain (longitudinal, circumferential, and radial) from endocardial, myocardial, and epicardial layers was analyzed using vendor-specific offline analysis software.
Two groups have previously carried out studies to track changes in circumferential strain values in the aortas of AngII apoE −/− mice [ 19, 21].
Because of the LV shortens from base to apex in systole, the fixed short-axis tracking that is required for circumferential and radial strain is more difficult than longitudinal tracking.
LV longitudinal and circumferential strain and strain rate was analyzed using two-dimensional speckle tracking echocardiography.
Two-dimensional speckle tracking, by which strain rate in all three directions (longitudinal, circumferential and radial) can be determined without angle dependency, has been employed in recent studies for assessment of LV systolic and diastolic dysfunctions in T2DM patients [ 57, 58].
Longitudinal and circumferential strain in septum and lateral wall mid-segments were calculated by speckle tracking in 2D grey scale images (frame rate 63 ± 11).
