Simultaneous 3D-flow field and compliant wall measurements in an abdominal aortic aneurysm flow using scanning-PTV
index matching scanning particle tracking velocimetry flow phantom
2015/8/25
We combine well established particle tracking with wall surface measurements using tomographic scanning and present results for the non-stationary 4D - flow field within an abdominal aortic aneurysm (...
Perceiving motion while moving,or how pairwise invariants make optical flow cohere
Perceiving motion while moving pairwise invariants optical flow cohere
2015/8/13
Computer-generated sequences simulated observer movement toward 10 randomly placed poles, 1moving and 9 stationary. When observers judged their direction of movement, or heading, they used 3 related i...
First OpenFlow-based Software-Defined -Flow Architecture for Flex-Grid OFDMA Mobile Backhaul over Passive Optical Networks with Filterless Direct Detection ONUs
OpenFlow-based Software-Defined Flex-Grid OFDMA Mobile Backhaul Passive Optical Networks Filterless Direct Detection ONUs
2014/11/6
We demonstrate the first software-defined OpenFlow1.0-based flex-grid -flow architecture enabling 150Mb/s per-cell OFDMA MBH overlays onto bidirectional 10Gb/s PON, without any ONU-side optica...
Controlling the Flow of Light Using the Inhomogeneous Effective Gauge Field that Emerges from Dynamic Modulation
Inhomogeneous Effective Gauge Field Dynamic Modulation
2015/8/7
We show that the effective gauge field for photons provides a versatile platform for controlling the flow of light. As an example we consider a photonic resonator lattice where the couplin...
Controlling the Flow of Microscopic Particles—The Role of Beam Size
Optical Manipulation Optical Tweezers Directional Flow
2013/1/30
Flow of micro particles and fluids is important in many microscopic systems. Here we present details of our finding of a directional flow of micro particles due to a single beam optical trap. It was f...

Parallel microchannels Flow boiling Heat transfer Pressure drop Porous coating
2016/12/2
Three heat sinks with porous-coated parallel microchannels were fabricated by using a solid-state sintering method. The enhanced flow boiling of anhydrous ethanol in the porous-coated microchannels wa...
Energy-efficient Flow Aggregation for IPTV Program Delivery in Optical Backbone Networks with Multiple Line Rates
Networks multicast network optimization
2015/5/26
Considering energy efficiency for IPTV program delivery in optical backbone networks with multiple available line rates, we propose energy-efficient flow aggregation to guarantee that the total energy...
Scalable Control Plane architecture for Optical Flow Switched Networks
Optical networks network management control
2015/5/26
In OFS, users employ an off-band signaling protocol to request lightpaths for their large unscheduled bursty transactions, and the network dynamically schedules a dedicated, end-to-end lightpath for t...
Strong enhancement of streaming current power by application of two phase flow
Strong enhancement streaming current power two phase flow
2016/12/2
We show that the performance of a streaming-potential based microfluidic energy conversion system can be strongly enhanced by the use of two phase flow. Injection of gas bubbles into a liquid-filled c...

Present-day networks are being challenged by dramatic increases in bandwidth demand of emerging applications. We will explore a new transport, ”optical flow switching”, that will enable significant gr...
The Impact of Autonomic Dysreflexia on Blood Flow and Skin Response in Individuals with Spinal Cord Injury
Autonomic Dysreflexia Blood Flow Spinal Cord Injury
2009/5/19
Autonomic dysreflexia (AD) is an inappropriate response of the sympathetic nervous system that commonly occurs when individuals with spinal cord injury (SCI), at or above the sixth thoracic (T6) verte...
