75 In this article, we propose a framework to analyze a musical audio signal (sampled from a popular music CD) and determine its key, provide usable chord transcriptions, and obtain the hierarchical rhythm structure representation comprising the quarter-note, half-note, and whole-note (or measure) levels. This framework is just one specific aspect of the broader field of content-based analysis ...

A&met-Wang alebra is defined by three rules: i) go =yx; ii) x + x = 0; and iii) xx =O. K. T. Wang showed that these rules give a shortcut method for finding tbe joint resistance (or driving point reshance) of an electrical network. However, there are electrical systems more general than the KIrckhoff network. For these system regular matroids repiace‘ networks. It is shown in this paper that Wa...

In this paper we present a generative model for image sequences, which can be applied to motion segmentation and tracking, and to image sequence compression. The model consists of regions of relatively constant color that have a motion model explaining their motion in time. At each frame, the model can allow accretion and deletion of pixels. We also present an algorithm for maximizing the poste...

Tile Pasting P System is a computational model, based on the P System model, to generate two-dimensional tiling patterns using pasting rules at the edges of the regular polygons. Computational mechanism plays an important role in understanding the various complexities involved in the formation of complex patterns. In this paper we study the construction of non-periodic tiling patterns using cor...

This report is a collection of six articles on model checking in the abstraction/refinement framework. This framework is used by various techniques for tackling the state-space explosion problem that is frequently encountered in model checking. The articles collected in this report are (in order of appearance): 1. Counterexample-guided abstraction refinement. Clarke, Grumberg, Jha, Lu, Veith[2]...

Two of the most studied tile self-assembly models in the literature are the abstract Tile Assembly Model (aTAM) [7] and the Two-Handed Tile Assembly Model (2HAM) [4]. Both models constitute a mathematical model of self-assembly in which system components are four-sided Wang tiles with glue types assigned to each tile edge. Any pair of glue types are assigned some nonnegative interaction strengt...

Anderson and Putnam showed that the cohomology of a substitution tiling space may be computed by collaring tiles to obtain a substitution which “forces its border.” One can then represent the tiling space as an inverse limit of an inflation and substitution map on a cellular complex formed from the collared tiles; the cohomology of the tiling space is computed as the direct limit of the homomor...

CLIMATE POLICY 8 (2008) 577–587 Growing international trade has been one of the most important drivers for China’s recent economic growth. This growth has fed rapid increases in energy demand and carbon emissions since 2000. China is now the world’s largest emitter of carbon dioxide. There is mounting pressure from some in the international community for China to take specific actions to mitiga...
