Ensuring the QoE-Related Fairness to Reduce the User Abandonment Ratio

open access: yesSensors, 2021
Nowadays, it is quite a challenge for app owners to keep users engaged with an app. Currently, the level of user abandonment is one of the key parameters that application owners are interested in. To meet these challenges, we conduct an extended study of

Chemically‐Disordered Transparent Conductive Perovskites With High Crystalline Fidelity

open access: yesAdvanced Science, EarlyView.
Kinetically arrested, chemically disordered perovskite thin films exhibit exquisite crystalline fidelity, broad IR–UV transparency, and low resistivity, despite incorporating five mismatched 3d–5d cations, including Cr and W. This study unites electronic correlation, cation diversity, valence complexity, and disorder—enabling new transparent conductors

Optimal bandwidth allocation in a delay channel [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 2006
In this paper, we consider the problem of allocating bandwidth to two queues with arbitrary arrival processes, so as to minimize the total expected packet holding cost over a finite or infinite horizon. Bandwidth is in the form of time slots in a time-division multiple-access schedule.

A Study on Optimal Data Bandwidth of Recurrent Neural Network–Based Dynamics Model for Robot Manipulators

open access: yesAdvanced Intelligent Systems, EarlyView.
In this article, RNN–based learning method is proposed to achieve overall dynamic model of robot manipulators, which is established by optimal data‐bandwidth. The optimal data‐bandwidth is developed as a key behavior of the proposed method, which is designed on the loss function and its derivative.
