Measuring blood velocity using 4D-DSA: A feasibility study

A new optical feedback interferometer for measuring red blood cell velocity distributions in individual capillaries: a feasibility study in microchannels.

Measuring Velocity Changes along a Solar Chimney

The increasing consumption of energy from fossil fuels on the one hand and the pollution created by it on the other hand has always raised the concern of replacing clean and renewable energy with fossil fuels in the human mind. Generating electricity through clean energy can be a good solution to reduce pollutants and prevent global warming. One of the most available types of renewable energy i...

Measuring Red Blood Cell Velocity with a Keyhole Tracking Algorithm

A tracking algorithm is proposed to measure the velocity of red blood cells traveling through microvessels of tumors growing in skin flaps implanted on mice. The tracking is based on a keyhole model that describes the probable movement of a segmented cell between contiguous frames in a video sequence. When a history of movements exists, past, present and a predicted landing position define two ...

Quantification of resting myocardial blood flow velocity in normal humans using real-time contrast echocardiography. A feasibility study

BACKGROUND Real-time myocardial contrast echocardiography (MCE) is a novel method for assessing myocardial perfusion. The aim of this study was to evaluate the feasibility of a very low-power real-time MCE for quantification of regional resting myocardial blood flow (MBF) velocity in normal human myocardium. METHODS Twenty study subjects with normal left ventricular (LV) wall motion and norma...

Feasibility Study of 4D CAD in Commercial Construction

The Architecture, Engineering and Construction industry is under constant pressure to increase the quality and speed of its production delivery processes. This is due to the mutual competition amongst the industry's constituents and the growing demands of clients who expect faster delivery and higher quality. This has encouraged the AEC community to explore alternative ways in conducting projec...
