Quasi-monolithic mirror suspensions in ground-based gravitational wave detectors [PDF]

open access: yes, 2018
At the commencement of a new era in astrophysics, with added information from direct detections of gravitational-wave (GW) signals, this paper is a testament to the quasi-monolithic suspensions of the test masses of the GW detectors that have enabled the

Recent Developments on the Moment Problem [PDF]

open access: yes, 2017
We consider univariate distributions with finite moments of all positive orders. The moment problem is to determine whether or not a given distribution is uniquely determined by the sequence of its moments.

Photovoltaic power prediction based on improved grey wolf algorithm optimized back propagation [PDF]

open access: yesArchives of Electrical Engineering, 2023
At present, the back-propagation (BP) network algorithm widely used in the short-term output prediction of photovoltaic power stations has the disadvantage of ignoring meteorological factors and weather conditions in the input.

Optimal data transmission and pathfinding for WSN and decentralized IoT systems using I-GWO and Ex-GWO algorithms

open access: yesAlexandria Engineering Journal, 2023
Efficient resource use is a very important issue in wireless sensor networks and decentral-ized IoT-based systems. In this context, a smooth pathfinding mechanism can achieve this goal. However, since this problem is a Non-deterministic Polynomial-time (NP-hard) problem type, metaheuristic algorithms can be used.

Some remarks on the Jacobian conjecture and polynomial endomorphisms [PDF]

open access: yes, 2012
In this paper, we first show that homogeneous Keller maps are injective on lines through the origin. We subsequently formulate a generalization, which is that under some conditions, a polynomial endomorphism with $r$ homogeneous parts of positive degree ...
