FREQUENCY ANALYSIS OF PHOTOGRAPHIC OBSERVATIONS OF PULSATING STARS
Odessa Astronomical Publications, 2017 The Fourier analysis are performed for photoelectric and photographic B-observations (Goranskij and Shugarov, 1979) of RR Lyrae star RW Ari. Besides the main frequency f0 and four its first harmonics two more frequencies are found: f1 =f0 /3 and f2 =0 ...

Thermal Performance of a Counter-Flow Double-Pass Solar Air Heater With The Steady and Pulsating Flow [PDF]
Engineering and Technology Journal, 2023 The present work studied the influence of pulsating flow as an active method on the thermal performance of a double-pass solar air heater with a tubular solar absorber. A ball valve has been used as a pulse generator mounted at the downstream flow of the

Numerical study of local heat transfer in tube bundle in pulsating flow [PDF]
E3S Web of Conferences, 2023 Forced pulsating flows enhance the heat transfer of various heat exchange equipment; however, such flows remain poorly understood. A numerical simulation was used to study how the position of a cylinder in a tube bundle affects the heat transfer during ...

Pulsation frequency distribution in δ Scuti stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We study the frequency distributions of Delta Scuti stars observed by the Kepler satellite in short-cadence mode. To minimize errors in the estimated stellar parameters, we divided the instability strip into ten regions and determined the mean frequency distribution in each region.

Frequency of spontaneous pulsations of the central retinal vein [PDF]
British Journal of Ophthalmology, 2007 The central retinal vein is the only structure in the body which can be examined non-invasively, runs through the cerebrospinal fluid space, and has a shape that depends on the relationship between its internal pressure and the pressure in the space surrounding it.
