How accurate are the time delay estimates in gravitational lensing?
We present a novel approach to estimate the time delay between light curves of multiple images in a gravitationally lensed system, based on Kernel methods in the context of machine...

Statistical timing analysis with correlated non-gaussian parameters using independent component analysis
We propose a scalable and efficient parameterized block-based statistical static timing analysis algorithm incorporating both Gaussian and non-Gaussian parameter distributions, ca...

Topics over time: a non-Markov continuous-time model of topical trends
This paper presents an LDA-style topic model that captures not only the low-dimensional structure of data, but also how the structure changes over time. Unlike other recent work t...

A CMOS integrated linear voltage-to-pulse-delay-time converter for time based analog-to-digital converters
A novel 0. 13,um CMOS integrated linear voltage to pulse delay time converter (VTC) is proposed. The VTC ml architecture uses current starved inverters where the inverter delay ver...
