Non-negative Matrix Factorization, Convexity and Isometry.
In this paper we explore avenues for improving the reliability of dimensionality reduction methods such as Non-Negative Matrix Factorization (NMF) as interpretive exploratory data...

On Growth and Formlets: Sparse Multi-Scale Coding of Planar Shape
This paper presents a sparse representation of 2D planar shape through the composition of warping functions, termed formlets, localized in scale and space. Each formlet subjects t...

How to Enhance a Superscalar Processor to Provide Hard Real-Time Capable In-Order SMT
This paper describes how a superscalar in-order processor must be modified to support Simultaneous Multithreading (SMT) such that time-predictability is preserved for hard real-ti...

Exploiting spare resources of in-order SMT processors executing hard real-time threads
— We developed an SMT processor that allows a static WCET analysis of several hard real-time threads and uses the remaining resources for soft or non real-time threads. The analy...

Using Trace Scratchpads to Reduce Execution Times in Predictable Real-Time Architectures
Instruction scratchpads have been previously suggested as a way to reduce the worst case execution time (WCET) of hard real-time programs without introducing the analysis issues p...
