We propose a method, which we name kinetic compressive sensing (KCS), based on a hierarchical Bayesian model and on a novel reconstruction algorithm, that encodes sparsity of kinetic parameters. ... Parametric maps are reconstructed by maximizing the joint probability, with an Iterated Conditional Modes (ICM) approach, alternating the optimization of activity time series (OS-MAP-OSL), and kinetic ... compressive sensing (KCS DIRECT): like the previous one but with the addition of the prior term in (4) defined as in (6) . ...arXiv:1803.10045v1 fatcat:e5p6u4wfbzhmnbinkr5s3d7eqq

This work focuses on the implementation of a compressed sensing (CS) technique to accelerate imaging of PCr resynthesis following physical exercise, using a modified 3D turbo-spin-echo sequence and principal ... Compressed sensing benefits from the fact that the majority of practical signals (including MR images) can have a sparse representation in a known transform domain. ... Recently, compressed sensing (CS) (34) has emerged as a powerful tool that enables accurate reconstruction of signals from datasets that have been sampled below the Nyquist limit. ...doi:10.1002/mrm.24484 pmid:23023624 pmcid:PMC3504632 fatcat:aqjofla42vasdfirbcjeihvohq
Ten action classes randomly selected from Kinetics-400 with no fall examples, are employed to train our 3D ConvNet post compressive sensing with different types of sensing matrices on the original video ... Also, the performance obtained with Kinetics pre-trained 3D ConvNet on compressively sensed fall videos from benchmark datasets is better than the state-of-the-art techniques. ... When block based compressive sensing is performed over video frame, we get compressed measurements for the corresponding block. ...arXiv:2001.03463v1 fatcat:hvgu32hipvau3b5bymtd3nuia4

Approximately the whole of the con- vertible energy of a compressed gas is kinetic energy, accord- ing to the atomic theory, and when a compressed gas squirts through a hole the energy is still kinetic ... The idea that the second law of thermodynamics has any- thing in common with the ‘‘tendency of energy to change from the potential to the kinetic form’’ is not only non-sense but it is unqualifiedly false ...

Electric charge is a primary dimension of perception in the sense that movements (kinetic energy) of this tiny amount of “‘compressed energy”’ are sufficient to most appropriately characterize events ( ... Similarly, temperature, T, is a primary dimension of percep- tion in the sense that movements (kinetic energy) of a still larger form of compressed energy, molecules, are sufficient to most ap- propriately ...
</strong> Compressible plasma turbulence is investigated in the fast solar wind at proton kinetic scales by the combined use of electron density and magnetic field measurements. ... Both the scale-dependent cross-correlation (CC) and the reduced magnetic helicity (<i>σ</i><sub>m</sub>) are used in tandem to determine the properties of the compressible fluctuations at proton kinetic ... An alternative is that the compressible component on inertial scales is dominated by slow waves which are then damped, while on kinetic scales, the compressible component comes solely from KAWs. ...doi:10.5194/angeo-36-47-2018 fatcat:kvjprytg65dm3l6eowzutstseu
The purpose of this study was to determine how knee compression affected kinetic variables during vertical jumps. ... Ten healthy males, age 20s, performed a single maximum vertical jump and a ten-consecutive vertical jump trial without knee compression (control condition) and with knee compression. ...
