Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

Deep Underground Science and Engineering, EarlyView.
In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Exchange Rate Risk and Deviations From Purchasing Power Parity

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper proposes a new solution to the purchasing power parity (PPP) puzzles, arguing that investors' higher‐order risk attitudes, combined with higher‐order uncertainty about nominal exchange rates, as reflected by skewness and kurtosis, drive a risk premium that leads to deviations from PPP.

Effective Bandwidth Allocation for WiMAX Mesh Network [PDF]

Journal of Systemics, Cybernetics and Informatics, 2010
The aim of this paper is to reduce the media access delay in a WiMAX mesh network. We observe that as the number of subscriber stations (SS) in a neighborhood increases, the processes of transmission opportunity (TO) competition and 3- way handshake are ...

An integration of autonomic computing with multicore systems for performance optimization in Industrial Internet of Things

IET Communications, EarlyView., 2022
Abstract The goal of this work is to investigate how the self‐awareness characteristic of autonomic computing, paired with existing performance optimization rules, may be used in applications to minimise multi‐core processor performance concerns. The suggested self‐awareness technique can assist applications in self‐execution while also assisting other

The Efficiency of Green Development Between Eastern and Western Regions of China

International Studies of Economics, EarlyView.
ABSTRACT The Super‐SBM model was utilized to assess and quantify the effectiveness of green development (EGD) in China's eastern and western regions from 2004 to 2020. Building upon this, the kernel density estimation method, the Dagum Gini coefficient method, and the spatial panel convergence model were employed to investigate the dynamic changes ...
