Graphene‐Based Wearable Textile Triboelectric Nanogenerators and Biomechanical Sensors
Advanced Materials Technologies, EarlyView.This study presents a wearable textile‐based triboelectric nanogenerator (T‐TENG) using sprayed graphene enhanced with a PVA adhesion layer. The graphene‐based electrode demonstrates high electrical conductivity and robustness to multiple bends. The fabricated T‐TENG provides stable and efficient output, with strong responsiveness to biomotion.

2021 International Conference on Applied and Theoretical Electricity (ICATE), 2021
This paper presents equivalent Thevenin circuits for two connections (parallel-series (ps) and parallel-parallel (pp)), for the magnetic coupling coils (resonators), used in wireless active power transfer. Using the Circuit Symbolic Analysis Program, the equivalent voltage generator in respect of the load terminals in full symbolic form is obtained. It

IEEE Transactions on Power Electronics, 2021
This article presents an input-series output-equivalent-parallel (ISOEP) multi-inverter system for high-power wireless power transfer (WPT), where preisolation dc/dc converter is concealed to achieve higher efficiency, and the number of inverter modules is allowed to be flexibly adjusted to satisfy different voltage and power requirements.

Conditions for equivalence of gas exchange in series and parallel models of the lung
Respiration Physiology, 1977The Fick principle was applied to series and parallel compartmental lung models to determine whether conditions existed under which their differentiation was theoretically possible. Respiratory and inert gases were examined under assumptions of steady-state gas exchange, continuous ventilation and bloodflow, perfect mixing within each compartment and ...

Equivalency of series-parallel hybrid system using planetary gear and hybrid system using EVT
8th International Conference on Power Electronics - ECCE Asia, 2011The series-parallel hybrid system using a planetary gear realizes low-fuel consumption and restraining of the exhaust gas by performing an optimal control of the internal combustion engine (ICE) with various driving modes. On the other hand, the hybrid system using electric variable transmission (EVT) has been proposed.

Equivalent series and parallel equivalent circuits for metallized film capacitors
TENCON 2007 - 2007 IEEE Region 10 Conference, 2007The most popular general purpose power and signal capacitor, the multilayer polypropylene (MPP) capacitor, exhibits virtually zero conductance losses and negligible distributed inductance. Self resonance is principally determined by lead and package inductance which can be modeled by a lumped equivalent inductor external to the capacitor.

Parallel/series dependency and equivalence in generalized Markov's chains
Microelectronics Reliability, 1983Abstract In this paper the analytical solutions to generalized Parallel and Series Markov's Chains are presented. The states dependencies are derived and the condition of equivalence is considered. The results are analyzed with respect to fault tolerant computing system applications.

The Equivalent Subgraph and Directed Cut Polyhedra on Series-Parallel Graphs
SIAM Journal on Discrete Mathematics, 1992An equivalent subgraph of a directed graph \(G\) has the same reachability between vertices as \(G\). The families of minimal equivalent subgraphs and minimal directed cuts of a graph \(G\) form a pair of blocking clutters. The author shows that the minimal equivalent subgraph [directed cut] inequalities completely describe the directed cut [equivalent
