Complete extension: the non-signaling analog of quantum purification [PDF]

open access: yesQuantum, 2023
Deriving quantum mechanics from information-theoretic postulates is a recent research direction taken, in part, with the view of finding a beyond-quantum theory; once the postulates are clear, we can consider modifications to them. A key postulate is the

Application of Extension Sliding Mode Strategy to Maximum Power Point Tracking in Human Power Generation Systems

open access: yesApplied Sciences, 2015
Sliding mode strategy (SMS) for maximum power point tracking (MPPT) is used in this study of a human power generation system. This approach ensures maximum power at different rotation speeds to increase efficiency and corrects for the lack of robustness ...

Theory and Applications of Active Constellation Extension

open access: yesIEEE Access, 2021
Active constellation extension (ACE) was originally developed to reduce the peak-to-average-power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems with quadrature amplitude modulation (QAM).

Interpolation in local theory extensions [PDF]

open access: yesLogical Methods in Computer Science, 2006
In this paper we study interpolation in local extensions of a base theory. We identify situations in which it is possible to obtain interpolants in a hierarchical manner, by using a prover and a procedure for generating interpolants in the base theory as black-boxes. We present several examples of theory extensions in which interpolants can be computed

Research on Ride Comfort and Driving Safety under Hybrid Damping Extension Control for Suspension Systems

open access: yesApplied Sciences, 2020
This paper is concerned with the conflicting performances of ride comfort and driving safety for semi-active suspension systems. To alleviate this conflict, a novel hybrid damping extension control (HDEC) method is proposed.

Extensions of Perron–Frobenius theory [PDF]

open access: yesPositivity, 2012
The classical Perron-Frobenius theory asserts that for two matrices $A$ and $B$, if $0\leq B \leq A$ and $r(A)=r(B)$ with $A$ being irreducible, then $A=B$. This was recently extended in Bernik et al. (2012) to positive operators on $L_p(μ)$ with either $A$ or $B$ being irreducible and power compact.

Research on reliability comprehensive evaluation method of five-axis CNC machine tools based on AHP and extension theory

open access: yesThe Journal of Engineering, 2019
Currently, some five-axis CNC machine tools have almost achieved the same advanced level of the western countries in terms of functionality and performance. However, the reliability of system is much lower than similar foreign products.
