1 Supported by the Natural Science Fund Contract No. 69873007. Abstract In the monitoring system of power plant, the method of gathering real time data of sensors is often adopted. It not only increases the communication burden of monitoring system but also results in erroneous transmitting due to worse electromagnetism environment. For overcomring these shortcomings, we adopt a new approach --...

This paper proposes rigorous geometrical treatment of bioelectrodynamics, underpinning two fast–growing biomedical research fields: bioelectromagnetism, which deals with the ability of life to produce its own electromagnetism, and bioelectromagnetics, which deals with the effect on life from external electromagnetism.

It is considered a dimensional reduction of Ue(1)× Ug(1) 3 + 1-dimensional electromagnetism to 2 + 1-dimensions. It is shown that all the six electric and magnetic field vectorial components are present in the reduced theory and that they can be described in terms of vector gauge fields. The quantum structure is maintained in the absence of boundary effects. In the case where boundary effects a...

The gauge connections corresponding to electromagnetism, YangMills theory and Einstein gravity can be derived by assuming specific commutation relations between the phase-space variables of a first quantized theory. Extending the procedure to noncommuting coordinates leads to new types of dynamics, which are explored. In particular, the conditions for the coexistence of an electromagnetic backg...

In the general relativistic description of gravitation, geometry replaces the concept of force. This is possible because of the universal character of free fall, and would break down in its absence. On the other hand, the teleparallel version of general relativity is a gauge theory for the translation group and, as such, describes the gravitational interaction by a force similar to the Lorentz ...

Following de Broglie and Vigier, a fully relativistic causal interpretation of quantum mechanics is given within the context of a geometric theory of gravitation and electromagnetism. While the geometric model shares the essential principles of the causal interpretation initiated by de Broglie and advanced by Vigier, the particle and wave components of the theory are derived from the Einstein e...

In Einstein's general relativity, geometry replaces the concept of force in the description of the gravitation interaction. Such an approach rests on the universality of free-fall—the weak equivalence principle—and would break down without it. On the other hand, the teleparallel version of general relativity, a gauge theory for the translation group, describes the gravitational interaction by a...

Hydrodynamic turbulence is studied as a constrained system from the point of view of metafluid dynamics. We present a Lagrangian description for this new theory of turbulence inspired from the analogy with electromagnetism. Consequently it is a gauge theory. This new approach to the study of turbulence tends to renew the optimism to solve the difficult problem of turbulence. As a constrained sy...
