temperature profile determination in soils under adverse conditions of variable heat capacity and conductivity is a rather hard task. the heat capacity and conductivity are moisture dependent and both vary with the soil density. moisture movement on the other hand is temperature dependent and so the two interact. no single mathematical formulae as yet exists for anticipating the temperature dis...

This paper deals with the simulation of a unified series-shunt compensator (USSC) aimed at examining its capability in improving power quality in a power distribution systems. The USSC simulation model comprises of two 12-pulse inverters which are connected in series and in shunt to the system. A generalized sinusoidal pulse width modulation switching technique is

Phospholipase C treatment of vesicular subfractions of plasma membranes derived from the three functional domains of rat liver indicated that there is an asymmetric distribution of phospholipids across the bilayer of these membranes. The bile-canalicular and sinusoidal membranes were similar and different from the contiguous membrane.

On-line VCE_ON and VF Measurement This paper proposes an accurate method to estimate the junction temperature using the on-state collector-emitter voltage and load current. By the proposed method, the estimation error which comes from the different temperatures of the interconnection materials in the module is compensated. Finally, it leads to satisfactory estimated results. The proposed method...

This paper describes a low power clock distribution that utilizes sinusoidal clock waveforms and proposes registers that are able to cope with the overlapping clock edges. We can report power savings of 30% to 70% compared with conventional clocking schemes while maintaining traditional static CMOS design styles and logic levels.

A new technique is used to explore the structure of turbulent convecting flows. A sinusoidal temperature perturbation is superimposed on the bottom plate of a cylindrical convection cell filled with cryogenic helium gas and its decay is measured at the cell mid-height. The measurements allow the first dynamic estimate of the core part of the flow which conducts fluid effectively without any the...

The Harmonic Balance Technique (HBT) is used to analyze the steady state performance of a two–state quantum system interacting with a classical sinusoidal electromagnetic wave and with a thermal bath at a fixed temperature. The linear time–variant differential equations describing such a system can be solved to any number of harmonics and the results can be compared with those obtained with the...

A sinusoidal temperature perturbation is superimposed on the bottom plate of a cylindrical convection cell, and its decay is measured at the cell midheight. Rayleigh numbers up to Ra=10(13) and aspect ratios 1 and 4 are considered. The technique allows a dynamic measurement of the height of the layer interposed between the superconducting core and the boundary. This deduced height is in good ag...

In this paper we propose a new technique for feature extraction/selection based on the projection of sensor features in class space and taking into account the sensor variance. The proposed technique is inspired by the organization of the early stages in the biological olfactory system, and proves to be highly suitable for high-dimensional feature vectors with small number of training samples. ...
