The following document is a continuation of the Blue Planet Project, and again, is believed to be the personal notes and scientific dairy of a scientist who was.

A nonlinear theory is discussed for self-modulation of pulsar radio pulses. A nonlinear Schroedinger equation is derived for strong electromagnetic waves propagating in an electron-positron plasma.

The nonlinearities arising from wave intensity induced relativistic particle mass variation may excite the modulational instability of circularly and linearly polarized pulsar radiation.

Pulsar multifunction spectroscopy service pairs multiple detectors with a high-output pulsed neutron generator to provide stand-alone cased hole formation evaluation and reservoir saturation monitoring—all with a single tool. The result is comprehensive reservoir rock and fluid content data that is comparable to data acquired during openhole.

Our results may contribute to improve the understanding of physical processes in pair plasmas such as the formation and evolution of pulsar microstructures [1,[32] [33] [34][35][36].

A nonlinear model of modulational processes in the subsonic regime involving a linearly unstable wave and two linearly damped waves with different damping rates in a plasma is studied numerically.

We compute the maximum Lyapunov exponent as a function of the damping rates in a two-parameter space, and identify shrimp-shaped self-similar structures in the parameter by: 2.

Astrophysics and Cited by: 2. Chian and Kennel () showed that the nonlinearities arising in a model for strong electromagnetic waves propagating in an electron–positron plasma may excite the modulational instability of pulsar radiation, resulting in periodic wave trains or solitons which may account for the formation of pulsar by: In particular the supersonic Langmuir turbulence can operate in two regimes: (1) the electrostatic supersonic modulational instability is excited when W > y.

and feoAo W > y^^k^o and feo-^o > I1' These two supersonic regimes are char- acterized by the excitation of non-resonant ion-acous- tic waves such Cited by: 8. Wave propagation in a cold, collisionless, two-component plasma is analyzed by considering, first, the frame of reference in which the field has no space dependence, and then applying a Lorentz transformation to obtain a wave whose space-time dependence is a function of t — nz / c only, where n is a constant.

Wall Mount - IP A complete built-in enclosure (wall mounted). The IP65 rating makes it ideal for use in outdoor harsh weather conditions. Pulsar Properties For additional information about pulsars, see the books P ulsar Astronomy by Andrew Lyne and Francis Graham-Smith and H andbook of Pulsar Astronomy by Duncan Lorimer and Michael Kramer.

Known radio pulsars appear to emit short pulses of radio radiation with pulse periods between ms and seconds. Formation: The formation of a pulsar is very similar to the creation of a neutron star.

When a massive star with 4 to 8 times the mass of our Sun dies, it detonates as a supernova. PULSAR® Universal Test System The PULSAR test set includes a ROM-resident computer program.

PULSAR Manual 3 The PULSAR project is an Australian training and research project funded by the Victorian State Government’s Mental Illness Research Fund (MIRF).

PULSAR is based on the Refocus program from the UK. This project is testing a practical approach to address the vital issue of how different types of services.A plasma antenna is provided having an ionizer, which when energized, generates a bounded or unbounded plasma column extending along a vertical axis.

When ionization is initiated, the difference in the diffusion characteristics of ions and electrons and the resulting gas plasma produce a current pulse in a first direction.
