In this paper we introduce a method for generating unstructured meshes in parallel which are partitioned in a \good" way. When solving a partial dierential equation on a parallel distributed memory machine, the mesh should be decomposed so that the communication requirement of the numerical solver is minimised and also the amount of work to be performed on each processor is approximately equal....

Roughly speaking, music can be easily and cheaply accessed via Internet, but at the same time, finding certain music is still a difficult task. In this paper, a music retrieval system based on frequency descriptors is presented. The work flow of proposed system passes through two main phases: (i) the enrollment phase and (ii) the retrieval phase. In both phases, two models are presented (i.e., ...

Analysis of variance (ANOVA) refers to statistical models and associated procedures, in which the observed variance is partitioned into components due to different explanatory variables. It provides a statistical test concerning if the means of these several groups are all equal. In its simplest form, ANOVA is equivalent to Student's t-test when only two groups are invloved. The analysis of var...

Any two polygons of equal area can be partitioned into congruent sets of polygonal pieces, and in many cases one can connect the pieces by flexible hinges while still allowing the connected set to form both polygons. However it is open whether such a hinged dissection always exists. We solve a special case of this problem, by showing that any asymmetric polygon always has a hinged dissection to...
