iSPD: An iconic-based modeling simulator for distributed grids
Simulation of large and complex systems, such as computing grids, is a difficult task. Current simulators, despite providing accurate results, are significantly hard to use. They usually demand a strong knowledge of ...
Simulation in paediatric urology and surgery, part 2: an overview of simulation modalities and their applications
Surgical training has changed radically in the last few decades. The traditional Halstedian model of time-bound apprenticeship has been replaced with competency-based training. In our previous article, we presented an ...
Simulation in paediatric urology and surgery. Part 1: an overview of educational theory
Surgical training has changed radically in the last few decades. The traditional Halstedian model of time-bound apprenticeship has been replaced with competency-based training. Advanced understanding of mastery learning ...
One-port nonlinear electric circuit for simulating grounding systems under impulse current
(Elsevier B.V., 2016-01-01)
A one-port nonlinear electric circuit to simulate grounding systems behaviors under high impulse currents is presented. The circuit is based on Loboda's and Pochanke's equations, which describe nonlinear behaviors of soil ...
Selective current compensators based on the conservative power theory
This paper presents possible selective current compensation strategies based on the Conservative Power Theory (CPT). This recently proposed theory, introduces the concept of complex power conservation under non-sinusoidal ...
Computer tools to aid the learning and design steps for photovoltaic systems
This paper presents novel simulation tools to assist the lecturers about learning processes on renewable energy sources, considering photovoltaic (PV) systems. The PV behavior, functionality and its interaction with power ...
The effects of pinning on critical currents of superconducting films
Using molecular dynamics simulations, we analyze the effects of artificial periodic arrays of pinning sites on the critical current of superconducting thin films as a function of vortex density. We analyze two types of ...
