The three-phase-lag model and Green–Naghdi theory without energy dissipation are employed to study the deformation of a two-temperature fiber-reinforced medium with an internal heat source that is moving with a constant speed under a hydrostatic initial stress and the gravity field.  The modulus of the elasticity is given as a linear function of the reference temperature. The exact expressions ...

in the present attempt, flow behavior and thermal convection of one type of nanofluids in a disc geometry was investigated using computational fluid dynamics (cfd). influence of gravity induced sedimentation also has been studied. the commercial software, fluent 6.2, has been employed to solve the governing equations. a user defined function was added to apply a uniform external magnetic field....

There is a growing interest in the cosmologists for theories with negative energy scalar fields and creation, in order to model a repulsive gravity. The classical steady state cosmology proposed by Bondi, Gold and Hoyle in 1948, was the first such theory which used a negative kinetic energy creation field to invoke creation of matter. We emphasize that creation plays very crucial role in cosmol...

A fundamental difficulty in modeling global atmospheric circulation is the strong interaction among motions on a wide range of space and time scales. Explicit numerical representation of all the spatial scales that determine the global atmospheric circulation is impractical. An example of such difficulties is the effect of small-scale inertia-gravity waves on the circulation. Inertia-gravity wa...

A consistent definition of high dimensional compactified quantum field theory without breaking the Kaluza–Klein tower is proposed. Possible consequences are discussed for the scalar model. Introduction High dimensional field theoretical models are interesting from two main points of view. First one is the possibility to construct Unified Theories from high dimensional gravities at classical fie...

We construct an induced gravity (pregeometry) where both the Newton constant and the cosmological constant appear as integration constants in solving field equations. By adding the kinetic terms of ghosts and antighosts, an action of the induced gravity is transformed to a topological field theory. Moreover, by solving field equations of the topological field theory in the FRW universe, we find...

Acknowledging that what is currently defined as ‘pressure’ should not have reason to exist without the existence of a gravity field, the connection between thermodynamics and gravity can be easily made clear. Comprehensive thermo-gravitational equilibrium conditions may be defined without raising any doubt about the validity of the conventional thermodynamic and gravitational equilibrium condit...

Seafloor massive sulfide deposits form in remote environments, and the assessment of deposit size composition through drilling is technically challenging expensive. To aid evaluation resource potential seafloor deposits, three-dimensional inverse modeling geophysical field data (magnetic gravity) collected near can be carried out to further enhance geologic models interpolated from sparse drill...

In recent years, with the emergency of high precision inertial sensors (accelerometers and gyros), gravity compensation has become a major source influencing the navigation accuracy in inertial navigation systems (INS), especially for high-precision INS. This paper presents preliminary results concerning the effect of gravity disturbance on INS. Meanwhile, this paper proposes a novel gravity co...
