A musical piece typically has repetitive structures. Analysis of this structure can be used for music indexing, thumbnailing or segmentation. The research described here aims at automatically analyzing the repetitive structure of musical signals. First, we detect the repetition of each segment in a piece using dynamic programming. Second, we summarize this repetition information and infer the s...

The classiication technique by Non-Reducible Descriptors provides decision rules in term of Boolean formulae on object's key features. In this paper we present an extension of the Non-Reducible Descriptors that contains quantitative information. By Quantitative Non-Reducible Descriptor of an object, the distance to the descriptions of objects from another classes is explicitly expressed. This f...

We investigate the structural patterns of the appearance and disappearance of links in dynamic knowledge networks. Human knowledge is nowadays increasingly created and curated online, in a collaborative and highly dynamic fashion. The knowledge thus created is interlinked in nature, and an important open task is to understand its temporal evolution. In this paper, we study the underlying mechan...

We introduce the novel concept of graph alignment, a generalization of graph isomorphism that is motivated by the commonly used multiple sequence alignments. Graph alignments and graph isomorphisms are equivalent in the case of pairwise comparisons, but if many graphs should be analyzed simultaneously, graph alignments are more robust against noise and perturbations. Thus, graph alignments can ...

Structural priming refers to the tendency of speakers to reuse the same structural pattern as one that was previously encountered (Bock, 1986). The effectiveness of structural priming has been an issue of much discussion in the field of second language acquisition over decades. This study aims at investigating the role of structural priming in Chinese English-as-a-foreign-language (EFL) learner...

The purpose of the paper is to examine the nature of chemical concepts, and the ways in which they are applied in chemoinformatics systems. An account of concepts in philosophy and in the information sciences leads to an analysis of chemical concepts, and their representation. The way in which concepts are applied in systems for information retrieval and for structure–property correlation are r...

Exploring the chemistry of vanadyl ions (VO2+) with bis-β-diketone ligands, in pyridine reactions of vanadyl sulfate with 1,3-bis-(3-oxo-3-(2-hydroxyphenyl)-propionyl)benzene (H4L1) and 1,3-bis-(3-oxo-3-(2-hydroxyphenyl)-propionyl)-pyridine (H4L2), two novel clusters, [(VIVO)4(H2L1)4(py)4] (1) and [(VVO)4(VIVO)2 (O)4(L2)2(py)6] (2) were prepared and characterized. Due to the conformational flex...

Information cascades are ubiquitous in both physical society and online social media, taking on large variations in structures, dynamics and semantics. Although there has been much progress on understanding the dynamics and semantics of information cascades, little is known about their structural patterns. In this paper, we explore a large-scale dataset including 432 million information cascade...

in this essay, jelinki pottery (clinky- ware ceramics) has been studied as one types of ceramics at arsacides era. raw materials, quality of processing and baking conditions of potteries are some of effective factors in strength and stability of this material. employing purposeful methods of chemical analyses in order to examine such factors and in fact structural science of historical potterie...

This paper discussed an object-oriented design for general game using C# and XNA using design pattern. We presented application of structural patterns, creational pattern and behavioral pattern to create game sprite, manage game state and game sprites, different collision and rewards among sprites or between sprites and map; we also discussed how to apply design patterns to handle communication...
