A new method for coding generic audio signals at 64 kbit/s in the 20-15000 Hz bandwidth with a low delay is presented. It combines subband coding, Low Delay CELP algorithm and cascaded lterbanks. Our earlier works [1] show that, when using an equal bit rate on each subband, the resulting audio quality was not appropriate. We propose a new technique based on lattice quantization to avoid the sea...

We report new spectroscopic and photometric observations of the white dwarf companion to the pulsar PSR B0820+02. The white dwarf is a normal DA white dwarf with an effective temperature of 15000 K and a mass of 0.6 M . The mass and orbital period of this system confirm recent simulations of the evolution of a neutron star – main sequence binary with mass exchange and thus implicitely theoretic...

The glycosaminoglycans (GAGs) in two marine invertebrate molluscs such as Tridacna maxima and Perna viridis were analyzed. Both the species was found to contain variable amounts of GAGs in the form of heparin biomolecules as identified by metachromatic activity and agarose gel electrophoresis analysis. Anticoagulant property of the biomolecules was assessed by anti factor Xa activity. Their mol...

We investigate the variability of physical parameters in the Broad Line Region (BLR) of NGC 5548 using the Boltzmann plot (BP) method. We apply the method on the Balmer lines observed from 1996 to 2004, and find that variability earlier detected in the lines, is also present in the temperature. We find that the average temperature for the considered period was T≈ 10000 K, and that varies from 6...

"Juvenile pattern" of T wave inversion in the precordial leads of electrocardiogram was studied in 100 normal healthy Indians of 0 to 70 years of age in both sexes. Incidence of such pattern was observed in 25 subjects upto 19 years of age. Persons of weight/height ratio less than 30% had higher incidence of juvenile T waves. Maximum incidence (48%) of juvenile T waves was observed in the annua...

We report a case of fetal chylothorax and hydrops. Chylothorax is a very rare condition, occurring in approximately 1 in 10000-15000 pregnancies, with an overall mortality rate of 25% to 50%. It is the most common form of pleural effusion in the prenatal period. Available treatments include thoracocentesis, pleuro-amniotic shunting and pleurodesis and the optimal antenatal management and timing...

In this paper we employ different methods for constructing histograms from invariant features that are computed locally around a set of salient points. These points represent, together with their neighborhood, the most important visual information in an image. The features used for constructing the histograms are evaluations of Haar integrals with nonlinear kernel functions. The resulting histo...
