The impulsive riveting method is described as the punching and joining of sheet metal carried out using the impulsive energy of a weight accelerated by an air compressor. Parts are held together between the rivet and rivet-holder. A hole is made in the sheets by the high speed collision of rivet and a weight (approximately 100 m/s or more). Another method, punch riveting, joins the sheets by pr...

Let B = B(t), t ∈ R+ be an (N, d)-fractional Brownian sheet with Hurst index H = (H1, . . . , HN ) ∈ (0, 1) . Our objective of the present paper is to characterize the anisotropic nature of B in terms of H. We prove the following results: (1) B is sectorially locally nondeterministic. (2) By introducing a notion of “dimension” for Borel measures and sets, which is suitable for describing the an...

We propose a theoretical model of ferroelectric metal where spontaneous electric polarization coexists with the conducting electrons. In our we adopt scenario when electrons interact two soft transverse optical phonons, generalize it to case there is in system, and show that linear coupling phonons emerges as result. find this results anisotropic transport which has current voltage drop. Import...

In a normal Fermi liquid, Landau’s theory precludes the loss of single fermion, quantum coherence in the low energy/temperature limit. For highly anisotropic, strongly correlated metals there is no proof that this remains the case: we propose that quantum coherence for transport in some directions may be lost intrinsically. This should stabilize a novel, qualitatively anisotropic non-Fermi liqu...

Rare earth elements (REE) have been recognised as critical raw materials, crucial for many clean technologies. As the gap between their global demand and supply increases, the search for their alternative resources becomes more and more important, especially for the countries which depend highly on their import. Coal fly ash (CFA), which when not utilised is considered waste, has been regarded ...
