Firstly, simulation analysis of echo from a moving target under different ship motion conditions was conducted with a focus on the frequency shift and broadening characteristics of the target echo spectrum. The simulation results show that the non-uniform linear motion and yaw of the ship will ...
An example of non-uniform motion is a race car in a race. The car may start off driving at 50 mph and then accelerate to 100 mph. At turns, the car may have to slow down and decelerate. Because the car's speed is not constant, the car is moving with non-uniform motion. What is...
The effect of nonuniform motion on radar waveforms is discussed. By considering the physical model of a perfectly reflecting mirror with an arbitrary law of motion r(t), it is possible to determine the functional form of the scattered wave at the receiver for any waveform in general. The par...
Non-uniform load distributionRoller-raceway contact stateEnergy lossStiffness matrixThe roller linear motion guide (RLMG) is a key transmission component in heavy-load mechanical systems, and its internal non-uniform load distribution and stiffness greatly affect the stability of mechanical systems. To ...
2j. In this case, agents synchronize and then repel from similarly phased agents; since all share the same phase, the repulsion leads to uniform expansion. Supplementary Discussion 4 and Supplementary Fig. 11 address the expansion behavior for various values of \(J\) and find that at \(J=...
A difference scheme on a non-uniform mesh for the equations of one-dimensional magnetic gas dynamics A new difference scheme for the equations of the one-dimensional motion of a viscous heat-conducting gas in a magnetic field is studied. In the non-linear ... AA Amosov,AA Zlotnik - 《Ussr...

The #nite-grid instability has been studied thoroughly in uniform grids #1, 2#; a linear theory has been developed and non-linear e#ects have been observed in paradigmatic cases. In recent years, the #nite-grid instability has been reconsidered for non-uniform grids #3, 4#, as a number...
, along lipid domains [Borden et al. 2006]) or owing to a more uniform increase in the area per lipid molecule, resulting in an increase of the effective surface tension until the surface tension σwater of the surrounding medium is reached, again leading to a tensionless state (χ=Adσ...
