Color Doppler optical coherence tomography (CDOCT) is a functional extension of optical coherence tomography (OCT) that can image flow in turbid media. We have developed a CDOCT system capable of imaging flow in real time. Doppler processing of the analog signal is accomplished in hardware in the time domain using a novel autocorrelation technique. This Doppler processing method is compatible w...

The rapid development of virtual reality applications continues to urge better compression 360° videos owing the large volume content. These are typically converted 2-D formats using various projection techniques in order benefit from ad-hoc coding tools designed support conventional video compression. Although recently emerged standard, Versatile Video Coding (VVC) introduces specific tools, i...

With the frequent occurrence of geological disasters and extreme weather, pipeline failure accidents secondary caused by debris flow continue to occur. Aiming at impact thin on support pipeline, a multi-physical coupling model with vibration reduction is established based expansion model. The expansive fluid used simulate stress under action flow. results show that effect slurry concentrated in...

There is a conflicting literature regarding the possible presence of adrenergic innervation of the retinal circulation. The effect of a histologically confirmed left superior cervical ganglionectomy on the total retinal blood flow in eight anaesthetised female cynomolgus monkeys was determined. Near total unilateral ocular sympathetic denervation was confirmed by ipsilateral miosis, supersensit...

A DC converter with the benefits of reverse power capability, less switching loss and wide voltage operation is presented implemented for input applications such as fuel cell energy, photovoltaic (PV) system wind power. Two full bridge resonant circuits are used in to achieve bidirectional flow capability reduce losses on active devices. To overcome variation problem energy PV solar panel, topo...
