Computation of Incident Solar Energy
IBM Journal of Research and Development, 1975Computations of the daily and annual totals of the solar energy incident upon south-facing tilted flat surfaces were carried out for several cloudfree atmospheric models after taking into account, somewhat arbitrarily, the contribution due to sky radiation and that due to radiation reflected by the ground.

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.

A graphical approach to incident energy analysis
2017 IEEE IAS Electrical Safety Workshop (ESW), 2017The goal of an incident energy analysis is to determine the largest incident energy that a worker could be exposed to at a piece of electrical equipment. This is most commonly done using the IEEE 1584 method. It is a common observation when performing this analysis that minor variations in fault current can result in large changes in a protective ...

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.

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.

Lithium-ion energy storage battery explosion incidents
Journal of Loss Prevention in the Process Industries, 2021Abstract Utility-scale lithium-ion energy storage batteries are being installed at an accelerating rate in many parts of the world. Some of these batteries have experienced troubling fires and explosions. There have been two types of explosions; flammable gas explosions due to gases generated in battery thermal runaways, and electrical arc explosions

Arc-Flash Incident Energy Analysis: Renewal Recommendations
IEEE Industry Applications Magazine, 2021Generally accepted industry standards, such as National Fire Protection Association (NFPA) 70E-2018, require arc-flash incident energy analysis to be updated when changes occur in the electrical power distribution system, and the analysis shall be reviewed for accuracy at least every five years.

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.
