A 5G Beam Selection Machine Learning Algorithm for Unmanned Aerial Vehicle Applications
Wireless Communications and Mobile Computing, Volume 2020, Issue 1, 2020., 2020 The unmanned aerial vehicles (UAVs) emerged into a promising research trend within the recurrent year where current and future networks are to use enhanced connectivity in these digital immigrations in different fields like medical, communication, and search and rescue operations among others.

Dipole distortions in the intergalactic medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Abstract Baryonic feedback can significantly modify the spatial distribution of matter on small scales and create a bulk relative velocity between the dominant cold dark matter and the hot gas. We study the consequences of such bulk motions using two high-resolution hydrodynamic simulations, one with no feedback and one with very strong ...

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 The two‐dimensional hydrogen atom in an external magnetic field is considered in the context of phase space. Using the solution of the Schrödinger equation in phase space, the Wigner function related to the Zeeman effect is calculated. For this purpose, the Bohlin mapping is used to transform the Coulomb potential into a harmonic oscillator problem ...

Probing the Intergalactic Medium with Fast Radio Bursts [PDF]
, 2014 The recently discovered fast radio bursts (FRBs), presumably of extra-galactic origin, have the potential to become a powerful probe of the intergalactic medium (IGM). We point out a few such potential applications.

Simulating intergalactic medium reionization [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 We have studied the intergalactic medium (IGM) reionization process in its full cosmological context, including structure evolution and a realistic galaxy population. We have used a combination of high-resolution N-body simulations (to describe the dark matter and diffuse gas component), a semi-analytical model of galaxy formation (to track the ...

The Intergalactic Medium [PDF]
Highlights of Astronomy, 1980 Observations of Lyman-α absorption show that any gas present in the space between clusters of galaxies must be hot, and x-ray observations indicate that there may be present gas whose temperature at low redshifts is 4 × 108 K and whose density is about half the critical value for cosmology.

Evidence for strong extragalactic magnetic fields from Fermi observations of TeV blazars
, 2010 Magnetic fields in galaxies are produced via the amplification of seed magnetic fields of unknown nature. The seed fields, which might exist in their initial form in the intergalactic medium, were never detected. We report a lower bound $B\ge 3\times 10^{

Constrain intergalactic medium from the SZ effect map [PDF]
, 2006 In this paper, we try to detect the SZ effect in the 2MASS DWT clusters and less bound objects in order to constrain the warm-hot intergalactic medium distribution on large scales by cross-correlation analysis.

PECULIARITIES OF MIXING METALS IN INTERGALACTIC AND INTERSTELLAR MEDIA
Odessa Astronomical Publications, 2008 We review the current status of the problem of metal mixing in the intergalactic and interstellar media. We give simple arguments for inefficiency of mixing metals because of a saturation of hydrodynamic (Rayleigh-Taylor and Kelvin-Helmholz ...
