Variation in diurnal and nocturnal movements distances revealed in wintering dabbling ducks in the Mississippi Alluvial Valley

open access: yesWildlife Biology, EarlyView.
Movement of waterfowl during winter is central to resource acquisition and mortality avoidance, despite the imminent risk to survival and overall fitness induced by hunting disturbance and energy expenditure. Weather and other environmental conditions may influence movement by altering resource needs, in which ducks must balance the trade‐offs of ...

WaveLiteDehaze‐Network: A Low‐Parameter Wavelet‐Based Method for Real‐Time Dehazing

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Although the image dehazing problem has received considerable attention over recent years, the existing models often prioritise performance at the expense of complexity, making them unsuitable for real‐world applications, which require algorithms to be deployed on resource constrained‐devices.

Alternative transmission modes for telecommunications networks

open access: closedThe Annals of Regional Science, 2000
Since the introduction of competition in the telecommunications sector, private firms have been facing new possible choices concerning their telecommunications systems. To evaluate these possibilities the traditional microeconomic production theory proves to be helpful.

Telecommunications Transmission Survivability Overview

MILCOM 1987 - IEEE Military Communications Conference - Crisis Communications: The Promise and Reality, 1987
An upper bound on communication network survivability is the connectivity of the underlying transmission plant. Connectivity is the proportion of network node pairs that remain connected after a network sustains damage. This paper gives the functional relation of connectivity to key network survivability parameters and describes a method to optimize ...

Soliton transmission in telecommunication networks

IEEE Communications Magazine, 1994
Erbium-doped fiber amplifiers are a major breakthrough for soliton communication. Most of the difficult problems preventing soliton communication recently were solved using erbium-doped optical fiber amplifiers (EDFAs). Progress in optical soliton communication has been very rapid, since the invention of the 1.48 /spl mu/m laser diode pumped EDFA ...

Telecommunications for HVDC Transmission

IEEE Transactions on Power Apparatus and Systems, 1968
The control and operational principles of HVDC transmission are briefly reviewed. Basically no telecommunication is necessary for operation, with the exception of telephone connections. As the demand for service and system control increases, telecommunication requirements will grow. General requirements of telecommunications are summarized and specific

Comparative analysis of classical and new transmission lines for telecommunication systems

2000 10th International Crimean Microwave Conference. "Microwave and Telecommunication Technology". Conference Proceedings (IEEE Cat. No.00EX415), 2000
Comparative analysis results of the main features of classical and new types of transmission lines for different telecommunication MM-wave applications, have been presented. New lines are based on flat waveguide splitters both with (EH, HE odd and even modes) and without (E odd modes only) dielectric filling.
