SN 2017jgh is a type IIb supernova discovered by Pan-STARRS during the C16/C17 campaigns of Kepler/K2 mission. Here we present and ground based observations 2017jgh, which captured shock cooling progenitor breakout with an unprecedented cadence. This event presents unique opportunity to investigate progenitors stripped envelope supernovae. By fitting analytical models lightcurve, find that was ...

In this paper, exergy of conditioned air, exergy efficiency, irreversibility, and entropy generation of common models of evaporative cooling have been investigated in five cities of Iran. Direct evaporative cooling (DEC), indirect evaporative cooling (IEC), and two-stage IEC/DEC as the most popular methods of cooling have been modeled. Atmospheric conditions are considered as the dead state of ...

1-type and biharmonic curves by using laplace operator in lorentzian 3-space arestudied and some theorems and characterizations are given for these curves.

Day-and-night radiative sky cooling has emerged as a potential alternative to conventional technologies such refrigeration-based air conditioning and evaporative wet cooling. Both can passively achieve sub-ambient without consuming electricity. Although both techniques are subject impacts from various weather conditions, the extents of under same conditions not well understood. In this work, we...

Thermodynamics of charged and slowly rotating black holes in 4D Gauss–Bonnet gravity has attracted a great deal attention due to its intrinsic complications rich phase structures. In this paper, we revisit the thermodynamics provide correct thermodynamic volume entropy. Thermodynamic geometries are powerful tool study microstructure holes. Based on Hessian matrix hole mass, introduce geometric ...

The performance of proton-exchange membrane fuel cell cooling system using coolant flow channels enhanced with baffles was numerically investigated. To do this, the maximum temperature of the cooling plate, temperature uniformity and also pressure drop along the flow channels were compared for different cases associated with number of baffles and their dimensions inside the channels. The govern...

Numerical simulations of a three-dimensional model of impingement and film cooling on a flat plate are presented and validated with the available experimental data. Four different turbulence models were utilized for simulation, in which SST  had the highest precision, resulting in less than 4% maximum error in temperature estimation. A simplified geometry with periodic boundary conditions is de...

In answer to a Comment by Belonoshko [Phys. Rev. B (to be published)], we show that the B1-liquid melting curve of MgO obtained using two-phase simulations is in good agreement with the published one obtained using the Clausius-Clapeyron equation in conjunction with separate single phase calculations of liquid and solid. The main point of the Comment by Belonoshko [1] regards the calculation of...

The time course of the appearance of cells showing a new phenotype, following treatment with a specific DNA, has been analyzed. A plot as a function of time of the number of cells showing the new property closely resembles the summation under a normal distribution curve. Describing the appearance of the new phenotype in these terms permits the definition of two parameters, the mean time, and th...
