Ophthalmic artery blood flow in 5 patients with internal carotid artery occlusion of sudden onset was monitored by an ultrasonic Doppler flowmeter to investigate the possible relationship to spontaneous recanalization of the occluded artery. The occluded internal carotid arteries of 2 patients were confirmed angiographically to recanalize and the reversed flow of their ophthalmic arteries chang...

in this paper, numerical investigation of a flat passive micromixer with heterogeneous surface properties that the flow through it, is driven by the electroosmotic flow have been presented. the governing equations, which consist of a laplace equation for the distribution of external electric potential, a poisson equation for the distribution of electric double layer potential, modified navier-s...

Abxtract: Cerebral Blood Flow and Internal Carotid A rtery Flow During Carotid Surgery • In a series of 17 patients operated on for stenosis of the internal carotid artery, measurement of the blood flow in the internal carotid artery by a squarewave electromagnetic flowmeter was performed simultaneously with measurement of the regional cerebral blood flow (rCBF) by the Xenon injection technique...

Fractional order control (FOC) has received widespread attention in recent years due to its efficient tuning capacity, intuitive concept, and enough flexibility. Again, FOC are known be robust with the open loop gain particular. However, design of demands knowledge model modified. But on other hand, linear active disturbance (LADRC) technique is free controller. In achieve better tracking perfo...

The control of flow balance at the die exit is key for successful extrusion polymers. complex cross-sectional variation in real-world hollow profiles intrinsically promotes imbalance cavity. Special considerations are required designing dies such profiles. design a door frame profile was computationally optimized this study with aid commercially available software package. velocity distribution...
