Incidence Energy of k-Uniform Hypertrees
MATCH – Communications in Mathematical and in Computer ChemistryFor a square matrix M, its energy E(M) is the sum of its singular values. Let H be a k-uniform hypergraph, and let B(H) be the incidence matrix of H. The incidence energy BE(H) of H is the energy of B(H). Let T n,d be the set of k-uniform hypertrees of order n and size r with diameter 3 ≤ d ≤ r − 1.

DC-Arc Models and Incident-Energy Calculations
IEEE Transactions on Industry Applications, 2009There are many industrial applications of dc power systems, but only a limited amount of scientific literature addresses the modeling of dc arcs. Since the early dc arc research focused on the arc as an illuminant, most of the early data was obtained from low current dc systems.

The Journal of Chemical Physics, 2001
We present calculations on the sticking of hyperthermal HCl to the basal plane (0001) face of ice Ih at normal and off-normal incidence. The dependence of the sticking probability on the incidence energy (Ei), the angle of incidence (θi), and the surface temperature (Ts) is discussed. Two sticking mechanisms are observed. For θi⩽30°, penetration of the

Impact of Distributed Energy Resources on Arc Flash Incident Energy
IEEE Transactions on Power Delivery, 2020Electric line personnel perform energized overhead line work and expose themselves to potential arc flash burns. Arc flash incident energy is calculated to determine proper personal protective equipment to protect line personnel against bodily injuries.

An Enhanced Method of Incident Energy Measurement
2018 IEEE IAS Electrical Safety Workshop (ESW), 2018Incident energy ratings of arc flash personal protective equipment are based on standard test methodology described in well-established industry tests. The generated arc primarily subjects test specimens to incident energy due primarily to radiation. However, an actual arc flash may include an ejected arc where there is a higher degree of convective ...

Gratings that diffract all incident energy*
Journal of the Optical Society of America, 1977Perfect blazing of reflection gratings to the n = −1 spectral order for both TE and TM polarizations simultaneously, as reported recently, is shown to be possible with rectangular grooves in 19.5° < θi < 59.4°, where θi is the angle of incidence from the surface normal. Design dimensions are verified experimentally at 35 GHz.

Optimization Methodology for Minimizing the Arc Flash Incident Energy
2018 IEEE Industry Applications Society Annual Meeting (IAS), 2018In this paper an optimization methodology for minimizing the arc flash incident energy has been presented. Arc flash incident energy for a given system mainly depends on fault current and protective device trip time. Protective device trip time is inversely related to the fault current.

Relationships between energy fluence and energy incident on, emitted by or imparted to a body
Physics in Medicine & Biology, 1979From knowledge of the energy and angular distribution of the fluence around a body, the energy incident on, emitted by or imparted to a body can be calculated. The calculation is easily performed if the quantity 'vectorial fluence' is used. Examples taken from the literature are used to illustrate the erroneous results obtained by integrating energy ...

Distribution of energy in polymers due to incident electrons and protons
Radiation Effects, 1988The recoil spectrum of nuclei in polymers for incident protons below 10 MeV in energy is calculated by using the Rutherford cross-section with screening corrections. Employing the work of McKinley and Feshbach on the Coulomb scattering of relativistic electrons by nuclei, the recoil spectrum of the nuclei is also calculated for electron energies ...
