We obtain expressions for the shear and the vorticity tensors of perfect-fluid spacetimes, in terms of the divergence of the Weyl tensor. For such spacetimes, we prove that if the gradient of the energy density is parallel to the velocity, then eithe...
Jun 24, 2018 · Introduction Hi, I'm the writer formerly known as "Jello_Biafra" from alternatehistory.com, and this the definitive version of the timeline I began working on almost ten years ago. It's grown a lot …

Aug 31, 2019 · Alan's found sufficient evidence at home that pretty much means Emma is going to be tried as an adult. The official charges are second-degree Attempted Homicide, Grand Theft, …
Terms like stretch and squeeze can also be used to denote force. In Physics, force is defined as: The push or pull on an object with mass causes it to change its velocity. Force is an external agent …
In physics, a force is an action that can cause an object to change its velocity or its shape, or to resist other forces, or to cause changes of pressure in a fluid. In mechanics, force makes ideas like ' …
Jul 29, 2022 · The fastest speed possible is the speed of light in a vacuum, where its velocity is 670,616,629 mph (1,079,252,848 km/h), equivalent to 10,337,670 cheetahs, 5,082 of the planet …
Intermittency in fluid turbulence can be evidentiated through the analysis of Probability Distribution Functions (PDF) of velocity fluctuations, which display a strong non-gaussian behavior at small scales. In this paper we investigate the occurren...
In this paper, we design a safe and efficient cruise control for the connected automated vehicle with access to motion information from multiple vehicles ahead via vehicle-to-vehicle (V2V) communication. Position and velocity data collected from a ch...
We consider the problem of vehicle following, where a safety distance to the leader vehicle is guaranteed at all times and a favourite velocity is reached as far as possible. We introduce the funnel cruise controller as a novel universal adaptive cru...
Water fountain stars (WFs) are evolved objects with water masers tracing high-velocity jets (up to several hundreds of km s$^{-1}$). They could represent one of the first manifestations of collimated mass-loss in evolved objects and thus, be a key to...
