Journal of Mechatronics and Robotics, Published online: 25 May 2026; doi:10.3844/jmrsp.2026.1.8 In an era increasingly defined by digital interconnectivity, the physical security of sensitive hard-copy documents remains a persistent vulnerability in organizational infrastructure. Traditional fil...

Operational Technology (OT) is experiencing one of the most remarkable shifts in its history as increased OT and Information Technology (IT) systems converge to form unified, intelligent systems. The aim of this review article is to look at the most important technology trends that are currently changing the OT landscape and consider the impact of these on architecture, operation, and security fo…

Long-distance electric vehicle (EV) travel depends critically on charging infrastructure reliability. When stations fail or queues form unexpectedly, drivers face increased range anxiety and risk of getting stranded. In this demonstration paper, we present EVMapSim, a discrete-event simulator for modelling EV navigation and charging behaviour at a national scale. We demonstrate 10,000+ vehicles t…

User-centric cell-free massive MIMO is a key 6G technology to meet strict latency and energy-efficiency demandsof compute-intensive applications. In practical O-RAN deployments, the central unit and distributed unit compute capacityfluctuates with network-slicing dynamics. Relying on fixed compute resources and access-point (AP) clustering based solely onradio conditions leads to radio–compute mi…

6G paradigm enables massive network slicing for pervasive digitization across vertical industries, demanding scalable,sustainable, AI-driven zero-touch automation, particularly under non-IID conditions in live networks. This work introducesa cloud-native service-level agreement (SLA)-driven stochastic policy to guarantee a scalable and fast operation of constrainedfederated learning (FL)-based an…

With the increasing deployment of Reinforcement Learning (RL) for network optimization at the edge of wirelessnetworks, the RL workload emerges as a significant challenge. While the placement of general Machine Learning workloadsacross the cloud–edge continuum has been widely studied, existing solutions typically exclude RL techniques due to theirdistinct structure and operational requirements. I…

Sixth-generation (6G) wireless networks are expected to meet all the demands of the next decade, a feasibility that is onlypossible with advances in network design and management. This paper first proposes a unified resource management framework for a 6G-based network architecture that includes an Open Radio Access Network (O-RAN) deployment and then defines a hierarchical network energy control …

Hello , I have two PCB presented in the photo. The difference between them is the length of the inner line. I have extracted the s2p of the two of them. I know that using the length difference we can extract the s-parameters of the rectrangular fixtures at the edges of the line. What is the... Read more

Supposedly it stands for diode for alternating current, but I don't see how its behavior resembles a diode at all! Is it possible it was named after its structural resemblance to a triac and the fact ...

Chi Xu, the founder and CEO of XREAL, thinks the smart glasses business has finally reached a turning point.

Like other AI wearables, Amazon's Bee offers an odd combination of convenience and privacy anxiety.
