Novel Parabolic Mirror Microscope Illuminated with Cylindrical Vector Beams for Confocal and Tip Enhanced Super Resolution ImagingDespite the popular employment of objective lenses as focusing devices, parabolic mirror (PM) is intensively used in quite different scopes of science. For instances, mirrors ...
the body. Thus, the external neutron beam has important limitations to be adequate for patient irradiation. Therefore, one of the challenges of BNCT lies in finding suitable neutron beams which is achieved with the combination of a neutron source and a neutron moderation device or Beam Shaping As...
. Sun et al.80applied the ABC algorithm to anticipate and optimise the concrete samples’ compressive strength. Chou et al.81prognosticated the shear strength in reinforced concrete deep beams. In mechanical engineering, Muthu et al.82conducted an optimal tolerance design for assembly with the goal...
Based on the Newton motion equation, for the flexible link body without constraints, the derivative of absolute momentum vector with regard to the center of mass Cm, is equal to the external loads vector: P˙Cm=QCm. The shift matrix can easily transform the momentum vector and the force vect...
Article metricsAbstract The concept of the time-modulated array has been emerging as an alternative to the complex phase shifters, which lowers the cost of the array feeding network due to the utilization of radio frequency (RF) switches. The various forms of hexagonal antenna array geometries ca...
and NO+and the 3DI goal is a reasonable separation of these ions. Thus the performance for these four species is important and worth evaluating. Unfortunately, our beam cannot produce clean O+or NO+beams in the required energy range. Instead, the 3DI’s mass separation capabilities for O+...
Maximumtop(xyz vector sum) displacement vs. time for (A) the original shell structure with 2.5 wall thickness and (B–C) standard lattice structures. Arrows indicate high frequency responses at peaks which are more evident for the lattices. *Note, in (C) the data is truncated at 0.182 s ...
1942 Accesses 3 Citations Metrics details Abstract A new ion composition and three-dimensional velocity analyzer, 3-Dimensional ion velocity and mass Imager (3DI), measures 3D velocity distribution functions (VDFs) for each major ion species in Earth’s topside ionosphere. The 3DI instrument is ...
The new crack front elements with Williams' eigenexpansion properties for 3D crack problems are proposed in this paper. In the presented method, the du
He interpreted the structural behaviour of the AFG bar for the power law exponent n. The vibration isolation and the force transmitted to the ground have been considered in the context of isotropic and FG beams in the literature. These studies used internal material damping and discrete damping ...
