Hace 8 horas · These inherent non-linearities give rise to the parametric resonance phenomenon in the driveline. The non-linear kinematical relationship between the input and output angular velocities of a U-Joint periodically oscillates in nature resulting in a \(\pi \) -periodic variation in the coefficients of the dynamic system.
Hace 8 horas · The phenomenon governing the passive energy pumping from a linear vibrating system to a nonlinear sink was initially investigated on a two-degree-of-freedom system in . ... Gendelman, O.: Energy pumping in nonlinear mechanical oscillators: part II resonance capture. J. Appl. Mech. 68(1), 42–48 (2000)
Hace 8 horas · The dynamic behavior of a pile-supported structure with a base isolator was investigated by using 1 g shaking table model tests considering soil–structure interaction (SSI). The emphasis was placed on evaluating the effect of the with/without developed base isolator on the dynamic behavior of end-bearing piles and structures. The experiment was performed through sweep tests and sinusoidal ...
Hace 8 horas · Johann Carl Friedrich Gauss (German: Gauß [kaʁl ˈfʁiːdʁɪç ˈɡaʊs] ⓘ; Latin: Carolus Fridericus Gauss; 30 April 1777 – 23 February 1855) was a German mathematician, astronomer, geodesist, and physicist who contributed to many fields in mathematics and science. He ranks among history's most influential mathematicians and has been referred to as the "Prince of Mathematicians".
Hace 8 horas · UHF half-wave dipole Dipole antenna used by the radar altimeter in an airplane Animated diagram of a half-wave dipole antenna receiving a radio wave. The antenna consists of two metal rods connected to a receiver R.The electric field (E, green arrows) of the incoming wave pushes the electrons in the rods back and forth, charging the ends alternately positive (+) and negative (−).
Hace 8 horas · Obviously, the strange phenomenon captured by NASA's solar satellite SOLO EUI HRI 174 on 2024/05/11 is an ordinary natural occurrence triggered by the eruption of solar material but a fact is that a huge CME hit Earth's magnetic field on May 10th, leading up to the biggest geomagnetic storm in almost 20 year.
Hace 8 horas · When the oscillation subsides again, this signal can be recorded with magnetic sensors. The basic principle is comparable to nuclear magnetic resonance in MRI. The researchers refer to the method as "Small-Scale Magneto-Oscillatory Localization" (SMOL).
