In this paper, a scaling analysis using a simple three-region structure was conducted for the unsteady natural convection boundary layer (NCBL) of a homogeneous Newtonian fluid with Pr > 1 adjacent to a vertical plate evenly heated with a time-dependent sinusoidal temperature. A series of scalings were developed for the thermal boundary thickness, the viscous boundary thicknesses, the maximum v...
In this paper, the performance of the recently proposed adaptive signal models on modeling speech voiceless stop sounds is presented. Stop sounds are transient parts of speech that are highly non-stationary in time. State-of-the-art sinusoidal models fail to model them accurately and efficiently, thus introducing an artifact known as the pre-echo effect. The adaptive QHM and the extended adapti...
Multi-resolution sinusoidal modeling is a method of representing audio signals as a sum of discrete sinusoids having various durations, and time-varying frequencies, phases, and amplitudes. This paper discusses the motivation for the multiresolution sinusoidal model (MRSM) and various structures used to compute it. A new filter-bank analysis structure is presented that is simpler than previous ...
Muon neutrino disappearance probability as a function of neutrino flight length L over neutrino energy E was studied. A dip in the L/E distribution was observed in the data, as predicted from the sinusoidal flavor transition probability of neutrino oscillation. The observed L/E distribution constrained nu(micro)<-->nu(tau) neutrino oscillation parameters; 1.9x10(-3)<Deltam(2)<3.0x10(-3) eV(2) a...
The purpose of this study was to characterize the deformation properties of a range of long-term denture soft lining materials using dynamic mechanical thermal analysis. Specimens were subjected to sinusoidal shear deformation at a frequency of 1 Hz and a strain of 64 microns peak to peak over a temperature range of 30-70 degrees C. The technique simulated the type and rate of deformation soft ...
abstract forecasting electrical energy demand and consumption is one of the important decision-making tools in distributing companies for making contracts scheduling and purchasing electrical energy. this paper studies load consumption modeling in hamedan city province distribution network by applying esn neural network. weather forecasting data such as minimum day temperature, average day temp...
Hot torsion test (HTT) has extensively been used to analysis and physically model flow behavior and microstructure evolution of materials and alloys during hot deformation processes. In this test, the specimen geometry has a great influence in obtaining reliable test results. In this paper, the interaction of thermal-mechanical conditions and geometry of the HTT specimen was studied. The commer...
A novel sensor principle for continuous monitoring of biofilms is presented. A small heater generates a steady sinusoidal heat signal. The resulting temperature oscillations are measured through a temperature sensor. The amplitude and phase shift of the oscillations are used as sensing parameters. The sensor system successfully detects surface attached bacterial growth within 30 minutes of inoc...
Aisha Rafi ,Vivek Kumar Sharma Department of mathematics, Jagan-Nath University, Jaipur, India. __________________________________________________________________________________________ Abstract A study of the free convective flow of a viscous fluid past a hot vertical porous plate is done with the assumption that the suction velocity is constant and normal to the plate and the plate temperatu...
