A thin dielectric slab over a conducting sheet is a low-loss slow-wave guiding system. When one introduces a magnetic wiggler into the system one may efficiently excite millimeter waves by passing a sheet electron beam just above the dielectric surface. For realistic parameters, the energy requirements on the beam are greatly reduced due to the wiggler. The frequency u, and the growth rate G ar...

Given a set of points in a Hilbert space that can be separated from the origin. The slab support vector machine (slab SVM) is an optimization problem that aims at finding a slab (two parallel hyperplanes whose distance—the slab width—is essentially fixed) that encloses the points and is maximally separated from the origin. Extreme cases of the slab SVM include the smallest enclosing ball proble...

Size reduction effects on the lattice dynamics of spin crossover (SCO) thin films have been investigated through molecular (MD) simulations density vibrational states. The proposed simple model structure and reduced force field allows us to obtain good orders magnitude sound velocity in both states takes into account contribution free surfaces properties very (below a thickness 12 nm). slab met...

Introduction Single Slab 3D turbo spin echo sequence with variable refocusing flip angles (aka SPACE) [1, 2, and 3] has been optimized for PDw, T2w and T1w contrast imaging. In order to obtain 3D high resolution and reduce the acquisition time to the clinical acceptable range, the TR has to be shortened dramatically compared to conventional TSE imaging. Moreover, a relative long echo train has ...

In this paper, properties of slab deformation in sizing press mill as one of the slab reduction processes in hot rolling mills have been evaluated using the elastoviscoplastic finite element method with explicit formulation. Effect of prarameters such as initial slab width and thickness, reduction, feed pitch, and anvil speed on factors such as dogbone formation, head and tail fishtail profile,...

High performance data movement remains a key problem despite continuing advances in the link speed of networks. The resurgent trend of dynamic networks, in which dedicated network resources can be requested and reserved on-demand, is contributing to an increasingly heterogeneous network landscape that is pushing the limits of existing transport layer protocols. We argue that the effective use o...

A subway train-steel spring floating slab track-tunnel coupling dynamic model, considering short and middle-long wavelength random track irregularities, and longitudinal connection between adjacent slabs of steel spring floating slab track, was developed. And the influence of slab length on dynamic characteristics of the system under different track conditions and train speeds are theoretically...
