This study focuses on the effect of the temperature response of a semi-infinite biological tissue due to a sinusoidal heat flux at the skin. The Pennes bioheat transfer equation such as rho(t)c(t)( partial differentialT/ partial differentialt)+W(b)c(b)(T-T(a))=k partial differential(2)T/ partial differentialx(2) with the oscillatory heat flux boundary condition such as q(0,t)=q(0)e(iomegat) was...

in this study, we have theoretically investigated the effect of electron stopper layer on internal temperature distribution of high performance vertical cavity surface-emitting laser emitting at 1305 nm.  simulation software pics3d, which self-consistently combines the 3d simulation of carrier transport, self-heating, gain computation and wave-guiding, was used. simulation results show that cha...

The determination of the optimal distribution of the catalytic activity profile, whichmaximizes the catalytic effectiveness, in created unsteady state conditions, is analyzed andtreated numerically for the case of a simple reaction. It was proven that the modulation, of thetemperature and the reactant concentration of the external bulk fluid, leads to a considerableincrease of the catalytic eff...

In this paper, the work of Guria and Jana [1] is extended to include the slip condition at the lower porous plate. The upper plate is subjected to a constant injection –Vo and the lower plate to a transverse sinusoidal suction velocity distribution, so that the flow becomes three dimensional. Approximate solutions were found for velocity and temperature using regular perturbation techniques. Th...

The dynamic phase transition has been studied in the two dimensional kinetic Ising model in presence of a time varying (sinusoidal) magnetic field by Monte Carlo simulation. The nature (continuous or discontinuous) of the transition is characterised by studying the distribution of the order parameter and the temperature variation of the fourth order cumulant. For the higher values of the field ...

The main objective of current study is investigation on thermo-hydraulic behavior nanofluids in a sinusoidal wavy channel as novel geometry under influences thermophoresis and Brownian motion. Differential quadrature method optimal homotopy asymptotic scheme have been employed to solve the momentum, continuity, energy nanoparticle fraction equations. validity proposed approaches evaluated by co...

Due to unique features like small thermal masses and reduced conductivities, miniaturized thermal sensors offer properties superior to those provided by comparable macroscopic measurement setups. In this contribution a micromachined device is applied to characterize the thermal transport properties of various liquids. By means of sinusoidal excitation of a heater structure placed on a micro-bri...

Using particle-in-cell simulation technique, we investigate the plasma and ionization asymmetry, electron ion energy distribution function in capacitive discharges excited by tailored waveforms. At a base frequency of 13.56 MHz, three different waveforms namely, sinusoidal, saw-tooth, square are applied for constant current density 50 A/m2 5 mTorr argon gas pressure. The results show that wavef...

To determine the role of the hepatic sinusoidal endothelium in the hepatic disposition of liposomal doxorubicin, we compared the hepatic pharmacokinetics of doxorubicin hydrochloride and the pegylated, liposomal formulation of doxorubicin (Caelyx). The multiple indicator-dilution technique and electron microscopy were used to study the disposition of doxorubicin and liposomal doxorubicin in the...
