Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method
Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed

Safety Listening in High-Risk Situations: A Qualitative Analysis of Responses to Safety Voice in Aviation. [PDF]
ABSTRACT Safety listening—responses to voice acts aimed at preventing harm—can avert organizational failures like airplane crashes. Research often focuses on attitudes and perceptions of listening using self‐report measures; consequently, little is known about how safety listening occurs behaviorally and influences safety outcomes in high‐risk ...

Propagation of positive, negative, and recoil leaders in upward lightning flashes
Leader propagation is a fundamental issue in lightning physics. The propagation characteristics of positive leaders and negative leaders are summarized and compared based on data from high-speed camera and electromagnetic field in rocket-triggered ...

Estimation of input energy in rocket‐triggered lightning [PDF]
Electric fields in the immediate vicinity (within 0.1 to 1.6 m) of the triggered‐lightning channel were measured with Pockels sensors at the International Center for Lightning Research and Testing at Camp Blanding, Florida. These fields and the associated currents measured at the base of a 2‐m strike object were used to compute the input power and ...

Return stroke current reflections in rocket‐triggered lightning [PDF]
AbstractTen upward propagating return stroke currents in eight triggered lightning flashes have been observed to reflect downward from 140 to 300 m altitude by way of measurements of the channel base current, close electric field and electric field derivative, and high‐speed video.

Wave Profile for Anti-force Waves with Maximum Possible Currents [PDF]
In the theoretical investigation of the electrical breakdown of a gas, we apply a one-dimensional, steady state, constant velocity, three component fluid model and consider the electrons to be the main element in propagation of the wave. The electron gas

Wave Profile for Current Bearing Antiforce Waves [PDF]
For fluid dynamical analysis of breakdown waves, we employ a one-dimensional, three-component (electrons, ions and neutral particles) fluid model to describe a steady-state, ionizing wave propagating counter to strong electric fields.
