Inline vector compression for computational physics [PDF]
Computer Physics Communications, 2021 A novel inline data compression method is presented for single-precision vectors in three dimensions. The primary application of the method is for accelerating computational physics calculations where the throughput is bound by memory bandwidth.

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 ...

Shock-reshock of zirconium to explore the effect of microstructure on the alpha-omega phase transformation [PDF]
EPJ Web of Conferences, 2021 Phase transformations play an important role in the mechanical behavior of materials subjected to extreme loading conditions. A series of shock-reshock experiments were fielded to determine whether the phase transitions in materials are significantly ...

Context-Aware Image Compression. [PDF]
PLoS ONE, 2016 We describe a physics-based data compression method inspired by the photonic time stretch wherein information-rich portions of the data are dilated in a process that emulates the effect of group velocity dispersion on temporal signals.

Energy Equality in Compressible Fluids with Physical Boundaries [PDF]
SIAM Journal on Mathematical Analysis, 2020 We study the energy balance for weak solutions of the three-dimensional compressible Navier--Stokes equations in a bounded domain. We establish an $L^p$-$L^q$ regularity conditions on the velocity field for the energy equality to hold, provided that the density is bounded and satisfies $\sqrtρ \in L^\infty_t H^1_x$.

Compression aware physical database design [PDF]
Proceedings of the VLDB Endowment, 2011 Modern RDBMSs support the ability to compress data using methods such as null suppression and dictionary encoding. Data compression offers the promise of significantly reducing storage requirements and improving I/O performance for decision support queries.
