We describe a novel method of adaptively controlling epileptic seizure-like events in hippocampal brain slices using electric fields. Extracellular neuronal activity is continuously recorded during field application through differential extracellular recording techniques, and the applied electric field strength is continuously updated using a computer-controlled proportional feedback algorithm....

Air flow through electric fan heater channel is governed by coupled, non-linear partial differential equations; these equations have to be solved within on irregular domain subject to various initial and boundary conditions. Computational Fluid Dynamics (CFD) replaces fluid flow equations by a set of algebraic equations, these algebraic equations can be solved using digital computers. Wall to a...

We computationally study the electrostatic potential profile and current carrying capacity of carbon nanotubes as a function of length and diameter. Our study is based on solving the non equilibrium Green’s function and Poisson equations self-consistently, including the effect of electronphonon scattering. A transition from ballistic to diffusive regime of electron transport with increase of ap...

Consider two perfectly conducting spheres in a homogeneous medium where the current-electric field relation is the power law. Electric field E blows up in the L∞-norm as δ, the distance between the conductors, tends to zero. We give here a concise rigorous justification of the rate of this blow-up in terms of δ. If the current-electric field relation is linear, see similar results obtained earl...

[1] The Equatorial Electrojet (EEJ) produces a strong magnetic signal in measurements of the low-orbiting CHAMP satellite. Six years of data with more than 30,000 dayside equator crossings provide a unique data basis to study this current system. In addition to scalar measurements used in previous studies, we have also inverted vector magnetic field measurements to gain accurate meridional prof...

An electric traction machine for an electric or a hybrid electric vehicle is usually designed for a specific operating point or cycle. For such an operating point or cycle, the masses and the cooling circuit of the electric machine determine the time dependent temperature distribution within the machine. For a specific load cycle, the thermal simulation of the machine can reveal possible mass a...
