Polynomial Data Compression for Large-Scale Physics Experiments [PDF]
Computing and Software for Big Science, 2018 The new generation research experiments will introduce huge data surge to a continuously increasing data production by current experiments. This data surge necessitates efficient compression techniques. These compression techniques must guarantee an optimum tradeoff between compression rate and the corresponding compression /decompression speed ratio ...

Compressible flow with vacuum and physical singularity [PDF]
Methods and Applications of Analysis, 2000 The first part is devoted to the study of Euler equations in one space dimension, in the compressible, isentropic, vacuum case with damping. The vacuum boundary is said to be physical if in a small neighborhood of the boundary \(0

Physical Mechanism of Concrete Damage under Compression [PDF]
Materials, 2019 Although considerable effort has been taken regarding concrete damage, the physical mechanism of concrete damage under compression remains unknown. This paper presents, for the first time, the physical reality of the damage of concrete under compression in the view of statistical and probabilistic information (SPI) at the mesoscale.
