Study on Ultra High Speed Cutting (4th Report)

Ultra high-speed sorting.

BACKGROUND Cell sorting has a history dating back approximately 40 years. The main limitation has been that, although flow cytometry is a science, cell sorting has been an art during most of this time. Recent advances in assisting technologies have helped to decrease the amount of expertise necessary to perform sorting. METHODS Droplet-based sorting is based on a controlled disturbance of a j...

Study on Braking Panels in High Speed Trains Using CFD

With speed increasing in high-speed trains, due to limitations of other types of brakes, aerodynamic brake has become an important braking method. In this task to make better use of brake’s panel different configurations are examined and the best panel shape which provides the reasonable drag coefficient is introduced. The results of simulations are carried out with the computational fluid dyna...

Ultra-High-Speed Reed-Solomon turbo decoder

—This article presents an FPGA implementation of an ultra-high-speed Reed-Solomon (RS) turbo decoder. A performance analysis is performed showing that RS Block Turbo Codes (RS-BTC) have decoding performance equivalent to Bose Ray-Chaudhuri Hocquenghem-Block Turbo Codes (BCH-BTC). A ratio between the decoder throughput and the decoder area is used to show the higher ef ciency of the RS full para...

Ultra High-Speed Radio Frequency Switch Based on Photonics

Microwave switches, or Radio Frequency (RF) switches have been intensively used in microwave systems for signal routing. Compared with the fast development of microwave and wireless systems, RF switches have been underdeveloped particularly in terms of switching speed and operating bandwidth. In this paper, we propose a photonics based RF switch that is capable of switching at tens of picosecon...
