Oriented wavelet transform on a quincunx pyramid for image compression
This paper presents a new image coding technique based on oriented 1D multiscale decompositions on a quincunx sampling grid. A transform obtained by adapting the lifting steps of ...

Weighted Zeta Functions of Graph Coverings
We present a decomposition formula for the weighted zeta function of an irregular covering of a graph by its weighted L-functions. Moreover, we give a factorization of the weighte...

Simultaneous logic decomposition with technology mapping in FPGA designs
Conventional technology mapping algorithms for SRAM-based Field Programmable Gate Arrays (FPGAs) are normally carried out on a fixed logic decomposition of a circuit. The impact o...

Multi-scale dual morse complexes for representing terrain morphology
We propose a new multi-scale terrain model, based on a hierarchical representation for the morphology of a terrain. The basis of our morphological model is a dual Morse decomposit...

Distributed Query Optimization in the Stack-Based Approach
Abstract. We consider query execution strategies for object-oriented distributed databases. There are several scenarios of query decomposition, assuming that the corresponding quer...
