Schur's test for integral operators states that if a kernel K:X×Y→C satisfies ∫Y|K(x,y)|dν(y)≤C and ∫X|K(x,y)|dμ(x)≤C, then the associated operator is bounded from Lp(ν) into Lp(μ), simultaneously all p∈[1,∞]. We derive variant of this result which ensures acts boundedly on (weighted) mixed-norm Lebesgue spaces Lwp,q, p,q∈[1,∞]. For non-negative kernels our criterion sharp; is, only it spaces. ...

An experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. The first specimen was a reinforced concrete frame with solid-brick infill. The second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. The last specimen was a reinforced concrete frame without any infill. These three specimens were tested by pseudostatic method. Di...

We study the Doppler-cooling of radial two-dimensional (2D) Coulomb crystals trapped barium ions in a radiofrequency trap. Ions 2D experience micromotion an amplitude that increases linearly with distance from trap center, leading to position-dependent frequency modulation laser light each ion's rest frame. use two tones separated by approximately 100 MHz efficiently cool distinct regions diffe...

The use of spatial relational terms requires the selection of a reference frame and the construction of a spatial template. The reference frame divides up space, indicating above/below, front/ back, and left/right directions. Spatial templates are applied to reference frames and define regions in space that correspond to good, acceptable, and bad uses of particular spatial relations. In two exp...

By introducing the new concepts of characteristic rate curves and rate-curve decomposition, a generic source-modeling framework is developed for transform coding of videos. Based on this framework, the rate-quantization (R-Q) and distortion-quantization (D-Q) functions (collectively called R-D functions in this work) of the video encoder can be accurately estimated with very low computational c...

In this paper, we propose a speech-presence uncertainty estimation to improve the global soft decision-based speech enhancement technique by using the spectral gradient scheme. The conventional soft decision-based speech enhancement technique uses a fixed ratio (Q) of the a priori speech-presence and speech-absence probabilities to derive the speech-absence probability (SAP). However, we attemp...

The estimation of dand q-axis parameters is highly desirable, because they are fundamental parameters to many vector control algorithms in the d-q reference frame for fast and accurate responses. Using the finite element method (FEM) for the determination of the interior permanent magnet synchronous motor (IPM) reactance provides an accurate means of determining the field distribution. However,...

Correlations between charged particles in deep inelastic e + p scattering have been studied in the Breit frame with the ZEUS detector at HERA using an integrated luminosity of 6.4 pb ?1. Short-range correlations are analysed in terms of the angular separation between current-region particles within a cone centred around the virtual photon axis. Long-range correlations between the current and ta...
