New principle of busbar protection based on a fundamental frequency polarity comparison.
PloS one
Mar 21, 2019
To overcome the contradiction between speed and reliability in existing busbar protection schemes, a new busbar protection algorithm based on a polarity comparison of fundamental frequency currents is proposed. The algorithm extracts the fundamental ...
Inertia location and slow network modes determine disturbance propagation in large-scale power grids.
PloS one
Mar 21, 2019
Conventional generators in power grids are steadily substituted with new renewable sources of electric power. The latter are connected to the grid via inverters and as such have little, if any rotational inertia. The resulting reduction of total iner...
Cross-Device Computation Coordination for Mobile Collocated Interactions with Wearables.
Sensors (Basel, Switzerland)
Feb 15, 2019
Mobile devices, wearables and Internet-of-Things are crammed into smaller form factors and batteries, yet they encounter demanding applications such as big data analysis, data mining, machine learning, augmented reality and virtual reality. To meet s...
An electromagnetic anglerfish-shaped millirobot with wireless power generation.
Biomedical microdevices
Feb 11, 2019
Female anglerfishes have a lantern-shape luminous organ sprouting from the middle of their heads to lure their prey in the dark deep sea. Inspired by the anglerfish, we designed an electromagnetic anglerfish-shaped millirobot that can receive energy ...
Usability Evaluation of a Novel Robotic Power Wheelchair for Indoor and Outdoor Navigation.
Archives of physical medicine and rehabilitation
Aug 25, 2018
OBJECTIVE: To compare the Mobility Enhancement roBotic (MEBot) wheelchair's capabilities with commercial electric-powered wheelchairs (EPWs) by performing a systematic usability evaluation.
An inexact multistage fuzzy-stochastic programming for regional electric power system management constrained by environmental quality.
Environmental science and pollution research international
Oct 9, 2017
Electric power system involves different fields and disciplines which addressed the economic system, energy system, and environment system. Inner uncertainty of this compound system would be an inevitable problem. Therefore, an inexact multistage fuz...
Adaptive fuzzy sliding control of single-phase PV grid-connected inverter.
PloS one
Aug 10, 2017
In this paper, an adaptive fuzzy sliding mode controller is proposed to control a two-stage single-phase photovoltaic (PV) grid-connected inverter. Two key technologies are discussed in the presented PV system. An incremental conductance method with ...
Feature Selection and Parameters Optimization of SVM Using Particle Swarm Optimization for Fault Classification in Power Distribution Systems.
Computational intelligence and neuroscience
Jul 11, 2017
Fast and accurate fault classification is essential to power system operations. In this paper, in order to classify electrical faults in radial distribution systems, a particle swarm optimization (PSO) based support vector machine (SVM) classifier ha...
Study on electric energy consumed in intermittent series-parallel elastic actuators (iSPEA).
Bioinspiration & biomimetics
Apr 6, 2017
On compliant actuators, intermittent series-parallel elastic actuators (iSPEA) can reduce motor load by variable load cancellation through recruitment of parallel springs by a single motor. However, the potential to reduce electric energy consumed, c...
Control and Evaluation of a Powered Transfemoral Prosthesis for Stair Ascent.
IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society
Jan 20, 2017
This paper assesses the metabolic effort exerted by three transfemoral amputees, when using a powered knee and ankle prosthesis for stair ascent, relative to ascending stairs with passive knee and ankle prostheses. The paper describes a controller th...
