Distributed Real-Time Dynamic Security Assessment Using Intelligent Techniques

Maher Kayal, Theodoros Kyriakidis, Karthik Kumar

In real time scenario, transmission (of power) in power systems may not be always ideal i.e. they may be interrupted. As a result, the synchronization among the power generating modules may be lost. Loss of synchronization has a direct effect on the stabil ...

From nanotubes to single crystals: Co doped TiO2

László Forró, Arnaud Magrez, Endre Horvath, Richard Gaal, Helmuth Berger, Bálint Náfrádi, Jacim Jacimovic, Neda Nikseresht Ghanepour

Millimeter-sized cobalt doped rutile crystals with a bi-pyramidal shape are obtained by chemical vapour transport using scroll-type H2Ti3O7 nanotubes as a precursor in which Co2+ ions are introduced by a simple ion exchange method prior to the growth. Desp ...

Numerical investigation of hydrodynamics and heat transfer of elongated bubbles during flow boiling in a microchannel

John Richard Thome, Mirco Magnini

Flow boiling within microchannels has been explored intensively in the last decade due to their capability to remove high heat fluxes from microelectronic devices. However, the contribution of experiments to the understanding of the local features of the f ...

Modelling the Evolution in Microchemistry and its Effects on the Softening Behavior of Cold Rolled AlFeMnSi-Alloys during Annealing

Ke Huang

A dedicated diffusion controlled precipitation model for AlMnFeSi-alloys, based on classical nucleation and growth theory, has been implemented and coupled to a phenomenological softening model accounting for the combined effect of recovery and recrystalli ...

Electronic, vibrational, and transport properties of pnictogen-substituted ternary skutterudites

Nicola Marzari, Boris Kozinsky

First principles calculations are used to investigate electronic band structure and vibrational spectra of pnictogen-substituted ternary skutterudites. We compare the results with the prototypical binary composition CoSb3 to identify the effects of substit ...

Microstructure and thermoelectric properties of bulk and porous n-type silicon-germanium alloy prepared by HUP

Cyril Cayron

The optimization of powders preparation and consolidation process leads to the achievement of a high thermoelectric figure of merit (ZT=1.25 at 800°C) in an n-type silicon-germanium (SiGe) alloy hot pressed at low heating rate. It has been experimentally o ...

Influence of Thermocouple Thermal Inertia in Impingement Heat Transfer Experiments Using Transient Techniques

Peter Ott, Alexandros Terzis, Bernhard Weigand, Guillaume Wagner

A typical transient heat transfer experiment for an impingement cooling configuration requires usually a temperature step in the flow. A moving isotherm of the liquid crystal surface coating is then monitored using a video camera. However, for small imping ...

Pressure dependence of the large-polaron transport in anatase TiO2 single crystals

László Forró, Arnaud Magrez, Richard Gaal, Helmuth Berger, Jacim Jacimovic, George Cristian Vaju, Radomir Zikic

We have measured the pressure and temperature dependences of the resistivity and the thermoelectric power of anatase, TiO2. The resistivity varies with T-3 at high temperatures, and its absolute value is in the 1 Omega cm range. Below 60 K, the resistivity ...

Performance improvement of a micro thermomechanical generator by incorporating Galinstan (R) micro droplet arrays

In previous research we have demonstrated a micro thermomechanical pyroelectric generator (mu TMPG) as an alternative to thermoelectric generators to harvest ambient heat energy. In such a device, a thermal mass oscillates between a hot and a cold side by ...

Thermocouple Thermal Inertia Effects on Impingement Heat Transfer Experiments Using the Transient Liquid Crystal Technique

Peter Ott, Alexandros Terzis, Bernhard Weigand

The transient liquid crystal technique is widely used for impingement heat transfer experiments. Additionally, due to the difficulty of producing pure temperature steps in the flow, many authors assumed the fluid temperature evolution as a series of step c ...
