Long-range dependence has been observed in many recent Internet traffic measurements. Previous studies have shown that there is a close relationship between heavy-tailed distribution of various traffic parameters and the long-range dependent property. In this paper, we use a simple Markov chain model to argue that when the loss rate is relatively high, TCP’s adaptive congestion control mechanis...

The temperature dependent dielectric spectroscopic properties of two heteronuclear complexes of monoethanolamine (MEA) at a wide temperature range (303-413 K) were investigated by impedance spectroscopy, in the frequency range from 100 Hz to 100 kHz. The frequency dependence of the impedance spectra plotted in the complex plane shows semi-circles. The Cole-Cole diagrams have been used to determ...

Draft: February 1, 2008 In the standard big bang model, the expansion rate of the Universe is predicted to slow down as the Universe evolves. ,2 The deceleration parameter, q0, measures the present deceleration rate. The deceleration causes a deviation from the linear relation between distance and red shift (the Hubble law) at large red shifts. A proposed approach for determining q0 is to measu...

Interpreting observations of frequency-dependence in backscatter from the seafloor offers many challenges, either because multiple frequencies are used for different observations that will later be merged or simply because seafloor scattering models are not well-understood above 100 kHz. Hindering the understanding of these observations is the paucity of reported, calibrated acoustic measuremen...

A new form of stochastic resonance (SR), recently discovered in underdamped nonlinear oscillators for which the dependence of eigenfrequency upon energy has an extremum, is investigated. Its characteristic features are identified and discussed on the basis of linear response theory and the fluctuation dissipation theorem. In common with conventional SR (in bistable systems), sharp increases in ...

AIMS To assess the relationship of anterior tooth fractures with type of occlusion and craniofacial morphology. MATERIALS AND METHODS The study was conducted on 76 subjects of age group 9 to 13 years with at least one fractured permanent anterior teeth. Lateral cephalograms were taken and study models were prepared for each subject with prior consent of their parents. Then cephalometric traci...

In the past the global, fully coupled, timedependent mathematical model of the Earth’s thermosphere/ionosphere/plasmasphere (CTIP) has been unable to reproduce accurately observed values of the maximum plasma frequency, foF2, at extreme geophysical locations such as the Argentine Islands during the summer solstice where the ionosphere remains in sunlight throughout the day. This is probably bec...

The atrial versus ventricular activities of Class III agents with differing K+ channel blocking profiles were assessed in vitro in ferret atrial and right ventricular papillary muscles. In concentration-effective refractory period (ERP) response studies at 2 Hz and 32 degreesC, the selective IKr blockers dofetilide, E-4031 and d-sotalol, as well as ibutilide, an IKr blocker also reported to enh...

We have solved the equation for the two-frequency fourth-order moment of two parallel monochromatic plane waves having different frequencies and propagating through a randomly inhomogeneous medium. The solution procedure uses a two-scale expansion based on the smallness of a new parameter whose magnitude does not depend on the scattering strength. The results are shown to be valid for all value...
