Sparse Representation-Based Classification (SRC) is a face recognition breakthrough in recent years which has successfully addressed the problem with sufficient training images of each gallery subject. In this paper, we extend SRC to applications where there are very few, or even single, per Assuming that intraclass variations one subject can be approximated by sparse linear combination those other subjects, Extended Classifier (ESRC) applies an auxiliary variant dictionary represent...
Soil management practices are used to enhance soil organic carbon, fertility, and crop productivity around the world. However, accurate information about appropriate amount of straw incorporation is not available, because it generally believed that at least 30% surface should be covered by straw, which implemented in all field environments. Therefore, a two-year (2016–2017) experiment was conducted investigate impact different percentages tillage methods, i.e., reduced (RT) conventional...
In 2008, Michigan State University was selected to establish the Facility for Rare Isotope Beams (FRIB). Construction of FRIB accelerator completed in January 2022. Phased commissioning with heavy ion beams started 2017 normal-conducting source and radio-frequency quadrupole. April 2021, full driver linear (linac) commissioned, accelerated energies above 200 MeV/nucleon by 324 superconducting radiofrequency (SRF) resonators operating at 2 K 4 liquid-helium cooling. preparation high-power...
Real-time substructuring techniques are currently an advanced experimental method for testing large size specimens in the laboratory. In dynamic substructuring, whole tested system is split into two linked parts, part of particular interest or nonlinearity, which physically, and remanding numerically. To achieve near-perfect synchronization interface response between physical specimen numerical model, a good controller needed to compensate transfer dynamics, nonlinearities, uncertainties...
Because of the limitations testing facilities and techniques, seismic performance soil-structure interaction (SSI) system can only be tested in a quite small scale model laboratory. Especially for long-span bridge, smaller is required when SSI phenomenon considered physical test. The effect resulting from always coupled with dynamic performance, so that bridge considering cannot uncovered accurately by traditional method. This paper presented implementation real-time substructuring (RTDS),...
Following a rice or wheat harvest, large amount of crop residue (straw) is retained in fields. The straw often incorporated into the soil order to increase organic carbon storage and reduce erosion. However, it has become apparent that can significantly alter shear properties, which dramatically affect energy inputs for tilling other management practices. In this study, laboratory-remolded straw-soil samples were compared with field-collected samples; we found high correlations cohesion...
The Facility for Rare Isotope Beams (FRIB) is a major nuclear physics facility research with fast, stopped, and reaccelerated beams that was successfully commissioned in May 2022. A key capability of FRIB the production an acceleration uranium beam, but this requires to work at design limits lowest charge-to-mass ratio highest power density on beam intercepting devices. This paper presents techniques overcoming significant challenges accelerating culminating demonstration 10.4 kW target,...
In this paper we motivate the explicit validation of hold-time violations in silicon and propose a method for doing so. New failure model test pattern generation methodologies are defined.We outline conditions under which these tests can be applied reliably. We present results applying patterns on microprocessor discuss implications intermittent failures relevance hazards during timing analysis.

The sparsity of a signal is critical for compression and high performance obtained by utterly sparse signal. But real signals are not commonly, so transformation considered. In addition, the degree coefficients mainly determined quality transform base. Therefore, this paper constructs base (trained dictionary) K-SVD algorithm rolling element bearing vibration uses Orthogonal Matching Pursuit (OMP) to conduct representation simulation. Results show that trained dictionary can be more fitted...
