This paper presents a design environment for efficiently generating and analyzing application-specific Intellectual Property (IP) cores for system level signal processing algorithms. We present our view of a framework that integrates existing electronic design automation (EDA) tools to alleviate the designer from manually constructing the hardware models and analyzing their performance. Our fra...

In recent times there has been some interest in studying partial latin squares which have no completions or precisely one completion, and which are critical with respect to this property. Such squares are called, respectively, premature partial latin squares and critical sets. There has also been interest in related maximal partial latin squares. This paper will explore the connection between t...

Shifting to many-core architectures is becoming compulsory for real-time applications demanding intensive computing capabilities. Nonetheless, the gain in performance of many-core architectures does not come for free. In particular, it comes at the cost of predictability and determinism issues. Logical determinism is the property of programs that for the same sequence of inputs always give the ...

In some of the recently-developed algorithms for convex parametric quadratic programs it is implicitly assumed that the intersection of the closures of two adjacent critical regions is a facet of both closures; this will be referred to as the facet-to-facet property. It is shown by an example, whose solution is unique, that the facet-to-facet property does not hold in general. Consequently, som...

A critical set in an n× n array is a set C of given entries, such that there exists a unique extension of C to an n× n Latin square and no proper subset of C has this property. The cardinality of the largest critical set in any Latin square of order n is denoted by lcs(n). In 1978 Curran and van Rees proved that lcs(n) ≤ n2 − n. Here we show that lcs(n) ≤ n2 − 3n+ 3.

Quantitative structure-property relationships (QSPR) of critical temperatures with small numbers of physically significant molecular descriptors are developed using the CODESSA (comprehensive descriptors for structural and statistical analysis) technique. A highly significant one-parameter model correlates to the critical temperatures of 76 hydrocarbons at R2 ) 0.953. A successful three-paramet...

We report the behaviour of thermoresponsive block copolymers of n-butyl acrylate and N-alkyl acrylamides in [C2mim][NTf2]. Poly(N-isopropylacrylamide) exhibits an upper critical solution temperature in [C2mim][NTf2] whereas poly(n-butyl acrylate) has a lower critical solution temperature. Consequently, these polymers exhibit double thermo-responsiveness correlated with the macromolecular struct...

We use the methods developed with M. Lyubich for proving complex bounds for real quadratics to extend E. De Faria's complex a priori bounds to all critical circle maps with an irrational rotation number. The contracting property for renormalizations of critical circle maps follows. As another application of our methods we present a new proof of theorem of C. Pe-tersen on local connectivity of s...

The quantum Hall effect is studied numerically in modulated two-dimensional electron systems in the presence of disorder. Based on the scaling property of the Hall conductivity as well as the localization length, the critical energies where the states are extended are identified. We find that the critical energies, which are distributed to each of the subbands, combine into one when the disorde...

October 1995 Abstract. We use the methods developed with M. Lyubich for proving complex bounds for real quadratics to extend E. De Faria’s complex a priori bounds to all critical circle maps with an irrational rotation number. The contracting property for renormalizations of critical circle maps follows. In the Appendix we give an application of the complex bounds for proving local connectivity...
