Identifying harmonic attributes from online partial discharge data [PDF]

open access: yes, 2011
Partial discharge (PD) monitoring is a key method of tracking fault progression and degradation of insulation systems. Recent research discovered that the harmonic regime experienced by the plant also affects the PD pattern, questioning the conclusions ...

The Astonishing Behavior of Electric Eels

open access: yesFrontiers in Integrative Neuroscience, 2019
The remarkable physiology of the electric eel (Electrophorus electricus) made it one of the first model species in science. It was pivotal for understanding animal electricity in the 1700s, was investigated by Humboldt and Faraday in the 1800s, was ...

Social interactions between live and artificial weakly electric fish: Electrocommunication and locomotor behavior of Mormyrus rume proboscirostris towards a mobile dummy fish. [PDF]

open access: yesPLoS ONE, 2017
Mormyrid weakly electric fish produce short, pulse-type electric organ discharges for actively probing their environment and to communicate with conspecifics.

The active electric sense of weakly electric fish: from electric organ discharge to sensory processing and behaviour

open access: yesBIO Web of Conferences, 2016
Sensory systems have been shaped by evolution to extract information that is relevant for decision making. In order to understand the mechanisms used by sensory systems for filtering the incoming stream of sensory input, it is important to have a ...

Waveform generation in the weakly electric fishGymnotus coropinae(Hoedeman): the electric organ and the electric organ discharge [PDF]

open access: yesJournal of Experimental Biology, 2009
SUMMARYThis article deals with the electric organ and its discharge in Gymnotus coropinae, a representative species of one of the three main clades of the genus. Three regions with bilateral symmetry are described: (1)subopercular (medial and lateral columns of complex shaped electrocytes); (2)abdominal (medial and lateral columns of cuboidal and ...

Male-mediated species recognition among African weakly electric fishes [PDF]

open access: yesRoyal Society Open Science, 2018
Effective communication among sympatric species is often instrumental for behavioural isolation, where the failure to successfully discriminate between potential mates could lead to less fit hybrid offspring.

Design and construction of an Electric Fish Finder

open access: yesNeotropical Ichthyology
We provide notes on the design and construction of an Electric Fish Finder - a portable differential amplifier for detecting the electrostatic fields of gymnotiform knifefishes.

A JAR of Chirps: The Gymnotiform Chirp Can Function as Both a Communication Signal and a Jamming Avoidance Response

open access: yesFrontiers in Integrative Neuroscience, 2019
The weakly electric gymnotiform fish produce a rhythmic electric organ discharge (EOD) used for communication and active electrolocation. The EOD frequency is entrained to a medullary pacemaker nucleus. During communication and exploration, this rate can

Testing and characterisation of large high-energy lithium-ion batteries for electric and hybrid electric vehicles [PDF]

open access: yes, 2007
This thesis considers the drivetrain and battery system requirements of Hybrid Electric Vehicles. The data herein proves that a series hybrid electric drivetrain with Lithium-ion batteries and plug-in recharge promises to be viable and sustainable ...

A model for studying the energetics of sustained high frequency firing. [PDF]

open access: yesPLoS ONE, 2018
Regulating membrane potential and synaptic function contributes significantly to the energetic costs of brain signaling, but the relative costs of action potentials (APs) and synaptic transmission during high-frequency firing are unknown.
