A fast and accurate simulation method for high-speed clock trees with buffer insertions is proposed in this paper, where transmission line model is used in all branches of clock trees rather than only in main path. The proposed method is based on two-moment matching technique and can approximate all damping responses, with analytical formulas for time domain responses given. It is shown that th...

This paper presents an analytical performance prediction model and methodology that can be used to predict the execution time, speedup and similar performance metrics of a string matching algorithm running on a cluster of personal computers. The developed performance model has been checked on a 6-cluster of computers and it has been shown that this model is able to predict the parallel run-time...

We demonstrate that matching ad format to a consumer’s mode of information processing enhances advertising effectiveness. Relative to noncomparative ads, comparative ads are more effective when consumers use analytical processing. Conversely, noncomparative ads are more effective than comparative ads when consumers use imagery processing. When ad format is compatible with processing mode, infor...

With the aim of improving the efficiency of on-line modelling of virtual environments (VEs) in Internet-based telerobotics (IBT), this paper addresses the modelling of geometric primitives using only a single view of them. By studying the properties and constraints of the primitives under perspective projection, we propose a searching method that uses virtual features as matching templates for ...

The evidence for string/string-duality can be extended from the matching of the vector couplings to gravitational couplings. In this note this is shown in the rank three example, the closest stringy analog of the Seiberg/Witten-setup, which is related to the Calabi-Yau WP 4 1,1,2,2,6(12). I provide an exact analytical verification of a relation checked by coefficient comparison to fourth order ...

We get back to the computation of the leading finite size corrections to some random link matching problems, first adressed by Mézard and Parisi [J. Physique 48 (1987) 1451-1459]. In the so-called bipartite case, their result is in contradiction with subsequent works. We show that they made some mistakes, and correcting them, we get the expected result. In the non bipartite case, we agree with ...

We theoretically study second-harmonic generation in two-dimensional nonlinear photonic crystals and obtain a unified expression that combines nonlinear Raman-Nath diffraction, Čerenkov-type second-harmonic generation, and nonlinear Bragg diffraction. The analytical solution is deduced, and the theoretical result coincides well with the nonlinear Raman-Nath, nonlinear Čerenkov, and nonlinear Br...

We apply the covariant derivative expansion of the Coleman-Weinberg potential to vector-like fermion models, matching the UV theory to the relevant dimension-6 operators in the standard model effective field theory. The γ matrix induced complication in the fermionic covariant derivative expansion is studied in detail, and all the contributing combinations are enumerated. From this analytical re...

The analysis of large amounts of data becomes an ever more important issue in science and business. Users, typcially domain experts, are faced with a huge challenge and require support. In this paper we look how data analysis can be intelligently supported and how soft computing methods can help. As examples, we look at some visualization concepts, approximate matching in frequent pattern minin...

An on-chip waveguide-based source of entangled photons capable of switching between generating time-energy entangled and hyperentangled (entangled in both time energy and polarization) photon pairs is proposed. The switching can be done all-optically by rotating the pump polarization. The source is based on multichannel phase matching in Bragg reflection waveguides achieved by engineering the F...
