This paper summarizes some of the current research challenges arising from multichannel sequence processing. Indeed, multiple real life applications involve simultaneous recording and analysis of multiple information sources, which may be asynchronous, have different frame rates, exhibit different stationarity properties, and carry complementary (or correlated) information. Some of these proble...

As graphs continue to grow, external memory graph processing systems serve as a promising alternative to inmemory solutions for low cost and high scalability. Unfortunately, not only does this approach require considerable efforts in programming and IO management, but its performance also lags behind, in some cases by an order of magnitude. In this work, we strive to achieve an ambitious goal o...

Direct numerical simulation with up to 10×109 scale grid points based on graphics processing unit computation is carried out investigate the bluntness effect hypersonic boundary-layer transition over a slender cone zero angle of attack at Mach 6. Four cases nose radii 1, 10, 20, and 40 mm are conducted, corresponding Reynolds number radius varies from 1.0×104 4.0×105. Random disturbances broad ...

This work primary objective is to develop an evaluation framework for studying bidimensional Fitts’ law applied to constant and variable gain mice. The authors, following the ISO9241 recommendations, will introduce an implementation of that framework. Suggestions about interesting tests to be performed and studies will be discussed (e.g. limited footprints tests, modification of the Fitts’ law ...

This paper reports two variable-gain amplifiers (VGAs) featuring a new pseudo-current-steering gain-tuning technique. In the first VGA (VGA-I), single-voltage-controlled dual-branch current mirror is developed as standalone gain control block. second (VGA-II), NMOS transistors, which are biased by tunable voltage, integrated into conventional common-source amplifier to steer away from part of t...
