This paper presents an embedded video compression with error resilience and error concealment using three dimensional SPIHT (3-D SPIHT) algorithm. We use a new method for partitioning the wavelet coefficients into spatio-temporal (s-t) blocks to get higher error resilience and to support error concealment. Instead of grouping adjacent coefficients, we group coefficients in some fixed intervals ...

An efficient, secure color image coder incorporating Color-SPIHT (C-SPIHT) compression and partial encryption is presented. Confidentiality of the image data is achieved by encrypting only the significance bits of individual wavelet coefficients for K iterations of the C-SPIHT algorithm. By varying K, the level of confidentiality vs. processing overhead can be controlled. For K=2, adequate secu...

A new combinatorial approach to the ribbon tableaux generating functions and q-Littlewood Richardson coefficients of Lascoux, Leclerc and Thibon [10] is suggested. We define operators which add ribbons to partitions and following Fomin and Greene [4] study non-commutative symmetric functions in these operators. This allows us to give combinatorial interpretations for some (skew) q-Littlewood Ri...

Binding energy of isospin asymmetric nuclei can be accessed with minimally modified formula along the lines of the liquid droplet model by partitioning the symmetry term into volume and surface terms. The volume symmetry energy coefficient extracted from finite nuclei provides a constraint on the nuclear symmetry energy. This approach also yields the neutron skin of a finite nucleus through its...

The possibility of heating of planetary cores by K radioactivity has been extensively discussed, as well as the possibility that K partitioning into the terrestrial core is the reason for the difference between the terrestrial and chondritic K/U. We had previously suggested that U and Th partitioning into FeFeS liquids was more important than Ko Laboratory FeFeS liquid, silicate liquid partitio...

We propose an extension of the Grevile’s partitioning method for computing the Moore-Penrose inverse of two-variable rational and polynomial complex matrices. Also we developed corresponding effective algorithm, applicable in the case when there are only few degrees in A(s1, s2) corresponding to nonzero coefficient matrices. These algorithms are implemented using symbolic and functional possibi...

A mixed-phase liquid chromatographic column was used to assay fluconazole in plasma, serum, and cerebrospinal fluid. The assay was linear from 0.2 to 20 micrograms/ml, with an average coefficient of variation of less than 5%. The partitioning of the drug between serum and cerebrospinal fluid was determined for 34 patients. The method was demonstrated to be suitable for both pharmacokinetic stud...

The downward flux of sinking particles is a prominent Hg removal and redistribution process in the ocean; however, it not well-constrained. Using data from three U.S. GEOTRACES cruises including Pacific, Atlantic, Arctic Oceans, we examined mercury partitioning coefficient, K d , water column. suggest that varies widely over ocean basins. We also investigated effect particle concentration compo...
