In this paper, we revisit two multi-terminal lossy source coding problems: the lossy source coding problem with side information available at the encoder and one of the two decoders, which we term as the Kaspi problem (Kaspi, 1994), and the multiple description coding problem with one semi-deterministic distortion measure, which we refer to as the Fu-Yeung problem (Fu and Yeung, 2002). For the ...

Sigma-Trees associated with residual vector quantization (RVQ) has been used for image-driven data mining to detect features and objects in a digital image with a degree of success. RVQ methods based on σ-tree structures have been designed to implement successive refinement of information for image segmentation. In such implementations, RVQ based novel methods are devised for pixel-block mining...

 Microsegregation is one of the most important phenomena occurs during solidification. It usually results in formation of some unexpected second phases which generally affect the mechanical properties and specially reduce the workability of casting products. The aim of this research is to study the effect of cooling rate and grain refinement on the microsegregation in Al-4.8 wt.% Cu. For this p...

This work investigates functional source coding problems with maximal distortion, motivated by approximate function computation in many modern applications. The distortion treats imprecise reconstruction of a value as good perfect if it deviates less than tolerance level, while treating that differs more level failure. Using geometric understanding the we propose hypergraph-based scheme for is ...

This study presents a comprehensive evaluation of the effects multi-channel spiral twist extrusion (MCSTE) processing on mechanical properties and structural evolution AA5083. The texture developed were mapped by electron backscatter diffraction (EBSD) for three successive passes compared with an as-annealed plate. An hardness tensile was presented correlated EBSD findings. displayed results re...

it is well-known that severe deformation to metals causes a direct grain refinement of the matrix without special heat-treatments due to the mechanism of dynamic continuous recrystallization (dcr). however, the microstructural revolution during severe deformation is seemed to be different depending on the deformation mode, namely the direction of deformation. in general, multi-directional defor...

aisi 304l austenitic stainless steel with different grain sizes of 0.5 -12 μm was obtained through the martensiticprocess. corrosion behavior of different samples was investigated in a 0.5m hcl solution using open circuitpotential, potentiodynamic polarization and electrochemical impedance spectroscopy tests. also, the correlationbetween the grain size and pitting corrosion resistance was asses...

Telehealth, as a provision of health care at a distance by usage of ICT, has also found its application in speech-language pathology (SLP) services. There are many advantages of remote usage of SLP services like extending the treatment or reaching remotely located people who need a treatment at affordable cost. While in the developed countries SLP telepractice is becoming common, there is littl...
