The annoyance of impulsive helicopter noise

open access: yes, 1981
A total of 96 impulsive and non-impulsive sounds were rated for annoyance by 10 subjects. The signals had the same amplitude spectrum with a maximum frequency of 4.75 kHz.

Signal Extraction and Clustering of Partial Discharge in Motor Insulation Using Temporal Correlation‐Based Clustering

open access: yesHigh Voltage, EarlyView.
ABSTRACT As one of the important links in energy transition and global energy interconnection, electric vehicles (EVs) are becoming increasingly major research topics in the field of energy. Partial discharge (PD) identification under repetitive impulsive voltages plays a pivotal role in evaluating the health of electric vehicle (EV) motor insulation ...

Crisis micro‐learning: A framework for understanding the micro‐flow of policy learning and Australia's COVID‐19 response

open access: yesAustralian Journal of Public Administration, EarlyView.
Abstract COVID‐19 has intensified interest in crisis policy learning, yet the micro‐level interactions among political, bureaucratic, and expert actors remain underexplored. We conceptualise an ideal‐type framework for the micro‐flow of crisis learning, an ordinarily epistemic and context‐specific process of individual‐level interactions, where lessons

Boredom, despondency, and the scourge that lays waste at noon: an anthropology of acedia Ennui, abattement et le fléau qui frappe à midi : une anthropologie de l'acédie

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Attentive to the ways that inertia can take hold of life, Catholic monks recognize despondency as a potential not only within the monastery, but in contemporary society more widely. Such experiences are regularly mapped onto an understanding of what early Christian monks termed ‘acedia’ (a Greek term that can be translated as ‘lack of care’). Taking as

Modified robust time delay estimation algorithm based on cyclostationarity in impulsive noise

open access: yesTongxin xuebao, 2013
The problem of time delay estimation (TDE) for cyclostationary signals in the presence of α-stable distribution impulsive noise and interfering signals was addressed.Since the conventional algorithms based on the second-order cy-clic spectral correlation

Mitigation of impulsive noise in OFDM channels using ANN technique

open access: yes, 2018
: Orthogonal frequency division multiplexer (OFDM) is a recent modulation scheme used to transmit signals across power line communication (PLC) channel due to its robustness against some known PLC problems. However, this scheme is greatly affected by the

Excavating Early Burawoy: Toward a Third Position in the Race‐Class Debates

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT This paper intervenes in contemporary sociological debates over the relationship between race and class by excavating the early writings of Michael Burawoy. Against the prevailing polarization between twin absolutist models in which either racism or capitalism alone possesses causal force, we argue that Burawoy articulates a third position—one
