geometry of the chute blocks in stilling basins plays a significant role in size and type of these structures. one of the most influencing factors in the design of the blocks is the fluctuating pressure which may cause fatigue on the blocks. despite investigations conducted by many researchers, there is not enough information about the pressure fluctuation around chute blocks in compacted still...

Blocks World (BW) has been a standard example of a planning domain for almost thirty years, and it is still commonly used to illustrate the capabilities both of formalisms and of planners. As a minimum, therefore, we should know certain basic things about the domain. It is clear that BW planning, in the sense of nding some plan or other, is trivial, and it was shown in 1991 that nding optimal (...

The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...

Image denoising by block matching and threedimensionaltransform filtering (BM3D) is a two steps state-ofthe-art algorithm that uses the redundancy of similar blocks innoisy image for removing noise. Similar blocks which can havesome overlap are found by a block matching method and groupedto make 3-D blocks for 3-D transform filtering. In this paper wepropose a new block grouping algorithm in th...
