A numerical solution of the modified Burgers' equation (MBE) is obtained by using quartic B-spline subdomain finite element method (SFEM) over which the nonlinear term is locally linearized and using quartic B-spline differential quadrature (QBDQM) method. The accuracy and efficiency of the methods are discussed by computing L 2 and L ∞ error norms. Comparisons are made with those of some earli...

I.I.T. Bombay, in collaboration with C.R.L., B.E.L., is working on developing a speech codec to provide communication quality speech at low bit rates. The codec is required to be robust to acoustic background noise and to channel errors. A sinusoidal coder based on the MBE (Multiband Excitation) model has been adopted as the basic speech representation due to its compact parameter set and the r...

Single quantum wells In0.53Ga0.47As/Ga0.47In0.53N0.021As0.949Sb0.03 /In0.53Ga0.47As with room-temperature photoluminescence peak wavelength at 2.04 mm were grown on InP substrate by solid-source molecular-beam epitaxy ~MBE!. In situ reflection high-energy electron diffraction was used to monitor the MBE growth. Double-crystal high-resolution x-ray diffraction and secondary ion mass spectrometry...

A series of AlxGa(1−x)As ternary alloys were grown by molecular beam epitaxy (MBE) at the technologically relevant composition range, x < 0.45, and characterized using spectroscopic ellipsometry to provide accurate refractive index values in wavelength region below bandgap. Particular attention is given O-band C-band telecommunication wavelengths around 1.3 µm 1.55 µm, as well 825 nm. MB...

The aim of the work described in this paper is to develop and evaluate the speaker normalization technique based on the test to reference speaker mapping. The method is suitable for uniform time-frequency representation of speech used in speech corrector systems. The normalized spectrum is generated after the analysis by synthesis for the given utterance using the MBE (multiband excitation) cod...

MBE growth on high symmetry surfaces depends to some extent on the shape of the terraces which form the embryos of each new atomic layer. The conditions for formation of compact or fractal terraces are discussed in two limits: large terraces, to which a continuous description applies, and small terraces, which require that the discrete nature of matter be taken into account. In both cases it is...

Starting this year, Molecular Biology and Evolution (MBE) will release a list of articles designated Citation Classics to celebrate and highlight the diversity and impact of MBE publications in molecular evolutionary research. Early (1983–2007) and Recent (2008–2012) Citation Classics were selected based on the highest number of citations per year in each period. For the Early category, life-ti...

A successful implementation of the Model-Based Enterprise concept (MBE) requires maximizing the potential benefits of annotated 3D models. The foundations of the MBE model are established by digital product definition data practices, which are currently regulated by standards such as ASME Y14.41-2003 and ISO 16792:2006. At the center of the MBE concept is the notion of CAD model reusability, wh...

MnBi2Te4 has recently been predicted and shown to be a magnetic topological insulator with intrinsic antiferromagnetic order. However, it remains challenge grow stoichiometric films by molecular beam epitaxy (MBE) observe pure order magnetometry. We report on detailed study of grown Si(1 1 1) MBE elemental sources. Films about 100 nm thickness are analyzed in stoichiometric, structural, magneto...
