U-Net with the iterative modified contrast scheme (IMCS) is proposed to solve inverse scattering problems (ISPs) in half-space. IMCS an innovative inversion technique that utilizes functions improve visibility of target regions and reconstruct internal structure objects. In applying alone, our method improves detection boundaries, enhancing noise immunity as well increasing structural similarity (SSI) through deep learning U-Net. We compare numerical results for 200-iteration 3-iteration...
Abstract Few-shot learning (learning with a few samples) is one of the most important cognitive abilities human brain. However, current artificial intelligence systems meet difficulties in achieving this ability. Similar challenges also exist for biologically plausible spiking neural networks (SNNs). Datasets traditional few-shot domains provide amounts temporal information. And absence neuromorphic datasets has hindered development SNNs. Here, to best our knowledge, we first dataset using...
Schottky junctions, formed by high work function metals and semiconductors, are important devices in electronics optoelectronics. The metal deposition traditional interfaces usually damages the semiconductor surface causes defect states, which reduces barrier height device performance. This can be avoided atomically smooth interface two-dimensional (2D) semiconductors. For better tailoring engineering, it is particularly to understand various effects such 2D under critical or boundary...
In the HT-7 superconducting tokamak, onset of a multifaceted asymmetric radiation from edge (MARFE) usually occurs in early ohmic discharges each experimental campaign before wall conditioning. The occurrence and location MARFE is identified by different diagnostic systems. An improved confinement mode plasma which was induced observed, global particle time increases 1.9 times. relaxation between event trigger L-H transition about 1.4 ms, following phase maintained for 40 ms. cools edge,...
The first plasma discharges were successfully achieved on the experimental advanced superconducting tokamak (EAST) in 2006. sawteeth behaviours observed by means of soft x-ray diagnostics and ECE signals EAST. displacement radius q = 1 surface was studied compared with result equilibrium calculation. density sawtooth oscillation also HCN laser interferometer diagnostics. structure EAST operational region detail. Plasma performance obviously improved boronization wall conditioning. It that...
Electron density fluctuations were measured by a CO2 laser collective scattering diagnostic system on the HT-7 tokamak. The relationship between electron and magnetohydrodynamics has been studied under three ohmic plasma discharge conditions (k(theta) = 12 cm(-1)): (i) only Mirnov activities, (ii) big sawtooth activities (iii) slight disruptions coexisting. It shown that obviously increase during or activities. A periodic burst in frequency spectrum of observed case (iii); detailed...
Abstract Avoiding the plasma instability, especially disruption is an important problem for stable operation of tokamak. Large-scale instabilities driven by free energy evolve nonlinearly and lead to disruption. The microscale turbulence highly sensitive change energy. paper show electron-scale evolution in pre-precursor phase TMs included with <?CDATA ${{\rm{CO}}}_{2}$?> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:msub> <mml:mrow> <mml:mi...
An electromagnetic wave coherent scattering system has poor longitudinal spatial localization. However, considering the variation of magnetic field lines and perpendicularity short-scale turbulence to these lines, we may be able obtain spatially localized measurements. In this paper, first describe method simulation results for measurements by a laser () collective diagnostic on HT-7. Second, study performance electron density fluctuations between channel 1 ( ) 2 during sawtooth activities....
