Power electronic converters, together with their loads, sources, and controls, form a coupled system that includes many nonlinear interactions, for instance due to pulse-width modulation (PWM) and feedback control.In this paper we develop a complete, nonlinear modeling approach for voltage-source inverters in the frequency domain, taking into accou
Post impact strain measurements of damaged plates were carried out experimentally after launching a spherical steel projectile at varying velocities against a fixed thin plate targets made of copper and steel materials and constrained at their outer periphery.Penetration or partial perforation of the target plates was achieved for projectile veloci
We have performed a series of two-dimensional and three-dimensional simulations of asteroid impacts into an ocean using the SAGE code from Los Alamos National Laboratory and Engine Plates Science Applications International Corporation.The SAGE code is a compressible Eulerian hydrodynamics code using continuous adaptive mesh refinement for following
Empirical research indicates that strategic alliances, like other organizational forms, emerge as an adaptive mechanism to market Bags uncertainty, and their developments over time reflect the co-evolution of distinctive firm capabilities and of industry and market activities.Interestingly, most strategic alliances go through similar revolutionary
Abstract Background Youth experiencing homelessness have disproportionate contact with the criminal legal system.This system contact represents a critical inflection point for enhancing risk or opportunities for stabilization; however, the policy and scholarly traditions examining the criminal legal system have not traditionally incorporated housin
