In this paper, we present a method for improving search efficiency in the area of ConstraintSatisfaction-Problems in finite domains. This method is based on the analysis of the “micro-structure” of a CSP. We call micro-structure of a CSP, the graph defined by the compatible relations between variablevalue pairs: vertices are these pairs, and edges are defined by pairs of compatible vertices. Gi...

Persistence diagrams, an important summary in topological data analysis, consist of a set ordered pairs, each with positive multiplicity. diagrams are obtained via Möbius inversion and may be compared using one-parameter family metrics called Wasserstein distances. In certain cases, produces sets pairs which have negative We call these virtual persistence diagrams. Divol Lacombe recently showed...

The low level acoustico-visual association reported by Yehia et al. (Speech Comm., 26(1):23-43, 1998) is exploited for audio-visual speech enhancement with natural video sequences. The aim of this study is to demonstrate that the redundant components of AV speech are extractible with a suitable representation which does not involve any categorization process. A comparative study is achieved bet...

The ROMVOX Text-toaSpeech synthesis system developed by our team is the first one that allowed the synthesis of any unrestricted Romanian text with intonation facilities on 1BM-PC compatible computers. During the last years of research several version of text-to-speech systems were achieved, trying to enhance their facilities. Our paper describes the present stage of our experiments performed i...

We present a next-generation architecture that addresses problems of dependability, maintainability, and manageability of I/O devices and their software drivers on the PC platform. Our architecture resolves both hardware and software issues, exploiting emerging hardware features to improve device safety. Our high-performance implementation, based on the Xen virtual machine monitor, provides an ...

Within the multicriteria aggregation-disaggregation framework, ordinal regression aims at inducing the parameters of a decision model, for example those of a utility function, which have to represent some holistic preference comparisons of a Decision Maker (DM). Usually, among the many utility functions representing the DM’s preference information, only one utility function is selected. Since s...

Thin nanofibers (NFs) of J-dominant aggregates with a thickness of 15 nm and thick NFs of H-dominant aggregates with a thickness of 25 nm were fabricated by the self-assembly of poly(3-hexylthiophene)-coated gold nanoparticles. The formation and decay dynamics of the charge carriers, which are dependent on the aggregate types of NFs, was investigated by time-resolved emission and transient-abso...

Automatic discrimination of speech and music is an important tool in many multimedia applications. Previous work has focused on using long-term features such as differential parameters, variances, and time-averages of spectral parameters. These classifiers use features estimated over windows of 0.5–5 seconds, and are relatively complex. In this paper, we present our results of combining the lin...

This paper presents a novel algorithm which generates three-dimensional face point trajectories for a given speech le with or without its text. The proposed algorithm rst employs an o -line training phase. In this phase, recorded face point trajectories along with their speech data and phonetic labels are used to generate phonetic codebooks. These codebooks consist of both acoustic and visual f...
