Ergonomics, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 16

Published: June 4, 2024

Preserving human well-being has become challenging for businesses, which continue efforts to overcome managing business processes concurrently, due the cumulative effects of psychosocial risks at work that may seriously impair one's health. By focusing on this need, paper proposes a more effective and realistic way measuring job satisfaction comprising by integrating multi-criteria decision-making (MCDM) methodology. Simplified PIvot Pairwise RElative Criteria Importance Assessment (PIPRECIA-S), i.e. selected MCDM method, is used weighting domains based opinions employees working company in Türkiye, who also provide their attitudes towards through 36 items Job Satisfaction Survey (JSS). This uses nine subscales JSS represent relevant risks. Three developed scenarios discuss effectiveness proposed subscale-weighted measurement presenting having different ranges standard scores relative scores.

A Novel High Isolation 4-Port Compact MIMO Antenna with DGS for 5G Applications

Published: May 24, 2023

This paper presents the design and realization of a simple low-profile, 4-port Multiple-Input-Multiple-Output (MIMO) antenna operating in mm-wave band supporting 5G communication technologies. As part methodology, initial stage involved development conventional monopole patch optimized for operation at 26 GHz, which is matched to 50 Ω stepped feed line. Afterward, square-shaped Defected Ground Structure (DGS) with semi-circles slots on edges placed ground improve isolation circular rectangular are incorporated as DGS optimize impedance bandwidth. Etching semi-circular shaped plane achieved more then 34.2 dB GHz band. In addition, an arrangement four symmetrical radiating elements positioned orthogonally minimize antenna’s physical size isolation. The proposed MIMO overall dimension 25 × mm2, printed Rogers 5880 substrate width 0.787 mm εr = 2.2. covers 10 bandwidth ranging from 25.28 - 28.02 whereas maximum gain attained purposed structure 8.72 dBi. Moreover, design, simulated measured advantages such high isolation, low ECC, compact good candidate usage areas smart devices, mobile phones, sensors applications.

Behind the Scenes: An Explainable Artificial Intelligence (XAI) on the Service Classification of the 5G/B5G Network

Published: Jan. 29, 2024

Fifth generation and beyond (5G/B5G) is part of the next mobile technology, which expected to offer more capacity faster speeds than previous Long-Term Evolution (LTE) network. These features enable 5G/B5G users a wide range services, including smart cities, entertainment multimedia, healthcare mission-critical applications that benefit entire economy communities. However, due growing demand, telecom service providers need provide better Quality (QoS) on their networks meet user expectations. Therefore, it necessary implement classification enables select right network slices for each improve QoS. Previous studies have predicted services using traditional machine learning algorithms such as random forest decision tree, achieving good accuracy. prediction based black-box models was not transparent enough, so could understand reliability interpretation results. this article aims model system performance 5G Key Performance Indicators (KPI) extend experiment Explainable Artificial Intelligence (XAI) by AI look behind scenes chosen networks, crucial make critical investment decisions around customer employee experience.
