TANDEL measurement of hydroacoustical particle motion

Measurement of Ground Motion

Tile need for a greatly expanded network of strong-motion accelerographs throughout the seismic regions of the world is stressed. A summary of the characteristics of currently available strong-motion accelerographs is presented, and the design details are given for an instrument suitable for acquiring the basic data needed by structural engineers for earthquake resistant design. It is shown tha...

Particle Consistency of Microscopic and Macroscopic Motion

The scenario of particle has been extensively written in the past, but its incompleteness is serious enough to break the connection of microscopic and macroscopic world. The th century’s cathode rays experiments by Perrin and Thomson are unable to prove whether the cathode rays are negatively charged or not. Here we propose, the subatomic and elementary particles in an atom through a capture pa...

Brownian motion of a self-propelled particle.

Overdamped Brownian motion of a self-propelled particle is studied by solving the Langevin equation analytically. On top of translational and rotational diffusion, in the context of the presented model, the 'active' particle is driven along its internal orientation axis. We calculate the first four moments of the probability distribution function for displacements as a function of time for a sp...

Complex Polarization Analysis of Particle Motion

Knowledge of particle motion polarization aids in identifying phases on threecomponent seismograms. The scheme of Montalbetti and Kanasewich (1970) is extended to analytic three-component seismograms, where the imaginary part of the signal is the Hilbert transform of the real part. This scheme has only one free parameter, the length of the time window over which the polarization parameters are ...
