Maximizing Lifetime of Three-Dimensional Corona-Based Wireless Sensor Networks

International Journal of Distributed Sensor Networks, 2014
In a wireless sensor network (WSN), the energy of nodes closer to the sink node is usually exhausted sooner than others. This is known as the energy hole problem, which heavily affects the lifetime of the network.

Seismological demonstration of perpendicular density structuring in the solar corona [PDF]

, 2008
The peculiarities of the propagating transverse waves observed in the solar corona with the CoronalMulti-channel Polarimeter (CoMP)indicate the existence of fine field structuring in the coronal density.

Accurate Identification Partial Discharge of Cable Termination for High-Speed Trains Based on S-Transform and Two-Dimensional Convolutional Network Algorithm

Sensors
Cable termination is an important part of energy transmission in high-speed trains, and it is also a weak link in the insulation. It is important to determine the insulation status of cable terminals by the detection results of partial discharge signals,

Resistance Distance and Kirchhoff Index of the Corona-Vertex and the Corona-Edge of Subdivision Graph

IEEE Access, 2018
The resistance distance is widely used in random walk, electronic engineering, and complex networks. One of the main topics in the study of the resistance distance is the computation problem.

Corona $C^*$-algebras and their applications to lifting problems.

MATHEMATICA SCANDINAVICA, 1989
For a non-unital (\(\sigma\)-unital) \(C^*\)-algebra A with multiplier algebra M(A), we define the corona to be the quotient \(C(A)=M(A)/A\). We show that every corona algebra has the countable Riesz separation property (CRISP): if \((x_ n)\) and \((y_ n)\) are sequences in \(C(A)_{sa}\), the first increasing the second decreasing, and such that \(x_ n\

Calculation and Analysis of Specific Losses of Active Power in Overhead Power Lines due to Corona in View of Climatic Data

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика
. It is a very challenging task to correctly use weather data to calculate the active power loss due to corona in overhead power lines. One of the significant reasons for this was the problem of accuracy of determining weather conditions and the use of ...
