Evaluation of Three Different Approaches for Automated Time Delay Estimation for Distributed Sensor Systems of Electric Vehicles

open access: yesSensors, 2020
Deviations between High Voltage (HV) current measurements and the corresponding real values provoke serious problems in the power trains of Electric Vehicle (EVs).

Functionally referential signals: a promising paradigm whose time has passed [PDF]

open access: yes, 2012
Finding the evolutionary origins of human language in the communication systems of our closest living relatives has, for the last several decades, been a major goal of many in the field of animal communication generally and primate communication ...

Neural responses to multimodal ostensive signals in 5-month-old infants [PDF]

open access: yes, 2013
Infants' sensitivity to ostensive signals, such as direct eye contact and infant- directed speech, is well documented in the literature. We investigated how infants interpret such signals by assessing common processing mechanisms devoted to them and by ...

The Indexical Voice: Communication of Personal States and Traits in Humans and Other Primates

open access: yesFrontiers in Psychology, 2021
Many studies of primate vocalization have been undertaken to improve our understanding of the evolution of language. Perhaps, for this reason, investigators have focused on calls that were thought to carry symbolic information about the environment. Here

Signal transduction and signaling networks

open access: yesMolecular Biology of the Cell, 2013
Cellular signaling can be complex and dynamic. In the past several decades, it has become clear that many signal transduction pathways are not simple one-way transmissions of upstream stimuli, but are mediated through extremely complicated networks. Our next challenge is to move beyond the static biochemical description of networks into developing a ...

Singular ARMA signals [PDF]

open access: yes, 2005
Singular random signals are characterized by the fact that their values at each time are singular random variables, which means that their distribution functions are continuous but with a derivative almost everywhere equal to zero.

The Roles of Parasitoid Foraging for Hosts, Food and Mates in the Augmentative Control of Tephritidae

open access: yesInsects, 2012
Ultimately, the success of augmentative fruit fly biological control depends upon the survival, dispersal, attack rate and multi-generational persistence of mass-reared parasitoids in the field.

Signal codes [PDF]

open access: yesProceedings 2003 IEEE Information Theory Workshop (Cat. No.03EX674), 2004
Motivated by signal processing, we present a new class of channel codes, called signal codes, for continuous-alphabet channels. Signal codes are lattice codes whose encoding is done by convolving an integer information sequence with a fixed filter pattern.

GNSS based relative navigation for intentional approximation of aircraft

open access: yesAviation, 2015
In aviation, satellite navigation is generally only used to determine the absolute position of aircraft. We show that the signals can also be used for safe relative navigation provided that a data link exists between the two aircraft.
