The surface electrical properties experiment

Gene Simmons, 1 David 14. StrangvJay, 2 L. Bannister,3 D. Cubley/+ G. LaTorraca,l J. D. Redman, 5 J. Rossiter, 6 and R. 14atts6 Abstract The surface electrical properties experiment is presently planned for Apollo 17. It uses two orthogonal, electric dipole antennas laid on the surface, each 70 m long (tip-to-tip), to transmit frequencies of l, 2.1, 4, 8. l, 16 and 32. 1 mhz. The signa 1 s ure ...

Determination of the electrical percolation threshold of Polystyrene-Graphene Oxide nanocomposite using the experiment and simulation methods

Carbon nanostructures via adding to a polymer matrix, while improving the electrical, mechanical and optical properties of the nanocomposites, are widely used in the industry, medicine, and agriculture. The authors presented several investigations on a new type of gamma dosimeter based on the polymer-carbon nanostructures nanocomposite. In this research, the electrical percolation threshold of ...

An experiment in automatic modeling an electrical drive system using fuzzy logic

Electrical drives are usually modeled using circuit theory with currents or linking fluxes chosen as state variables for the electrical part, and rotor speed or position for the mechanical part of the system. Often, the internal structure of the drive system contains nonlinear relations difficult to mode as for example dead-time, hysteresis, and saturation effects. On the contrary, if the avail...

Electrical conductivity in granular media and Branly’s coherer: A simple experiment

"Virtual" experiment for understanding the electrocardiogram and the mean electrical axis.

Educators have placed an emphasis on the development of laboratory materials that supplement the traditional lecture format. The laboratory materials should encourage active learning, small group discussion, and problem-solving skills. To this end, we developed a virtual experiment designed to introduce students to the theory and application of the electrocardiogram (ECG) and the mean electrica...
