UNDERTOW: Multi-Level Segmentation of Real-Valued Time Series
The discovery of meaningful change points, finding segments, in both categorical and real-value data time series is a well-studied problem. Prior segmentation algorithms and task...

The Logic of Time Structures: Temporal and Nonmonotonic Features
We Imbed Into a first order logic a representation language that combines atemporal knowledge with time stamps in a hierarchical fashion. Each time structure contains its own chro...

Accurate rise time and overshoots estimation in RLC interconnects
A closed form expression for the rise time of a gate driving a distributed RLC line is introduced that is within 8% of dynamic circuit simulations for a wide range of RLC loads. I...

An Algorithm for Segmenting Categorical Time Series into Meaningful Episodes
This paper describes an unsupervised algorithm for segmenting categorical time series. The algorithm first collects statistics about the frequency and boundary entropy of ngrams, t...

TACO: timing analysis with coupling
: The impact of coupling capacitance on delay is usually estimated by scaling the coupling capacitances (often by a factor of 2) and modeling them as grounded. This simple approach...
