Given a graph G (V, E) having vertices as points in the two-dimensional Euclidean space and edge-weights representing the Euclidean distances between those vertices, the Euclidean Leaf-Constrained Minimum Spanning Tree (LCMST) problem searches for a minimum cost spanning tree that has at least a specified number of leaf vertices L, 2 ≤ L ≤ |V| - 1. The problem is NP-hard and finds applications in facilities location, circuit, network design, and other domains also. The Euclidean LCMST (e-LCMST) problem arises when the domain is restricted to the Euclidean space. A well-known greedy spanning tree construction-based heuristic for the problem takes O(|V|4) time to compute low-cost LCMST but is restricted in its applicability to only small-sized instances. A recent less greedy heuristic for the e-LCMST problem obtains superior performance in O(|V|3) time. This paper proposes four clustering-based heuristics that obtain good solutions for the e-LCMST problem in O(|V|3) time. In the course of several experiments on standard and large complete graph instances, the proposed heuristics are shown to outperform the existing heuristics for the problem. © 2023 IEEE.

Extended Reality (XR) is one of the most important 5G/6G media applications that will fundamentally transform human interactions. However, ensuring low latency, high data rate, and reliability to support XR services poses significant challenges. This letter presents a novel AI-assisted service provisioning scheme that leverages predicted frames for processing rather than relying solely on actual frames. This method virtually increases the network delay budget and consequently improves service provisioning, albeit at the expense of minor prediction errors. The proposed scheme is validated by extensive simulations demonstrating a multi-fold increase in supported XR users and also provides crucial network design insights. © 2019 IEEE.

Noise and photon loss encountered on quantum channels pose a major challenge for reliable entanglement generation in quantum networks. In near-term networks, heralding is required to inform endpoints of successfully generated entanglement. If after heralding, entanglement fidelity is too low, entanglement purification may be utilized to probabilistically increase fidelity. Traditionally, purification protocols proceed as follows: generate heralded EPR pairs, execute a series of quantum operations on two or more pairs between two nodes, and classically communicate results to check for success. Purification may require several rounds while qubits are stored in memories, vulnerable to decoherence. In this work, we explore notions of optimistic purification, wherein classical communication required for heralding and purification is delayed, possibly to the end of the process. Optimism reduces the overall time EPR pairs are stored in memory, increasing fidelity while possibly decreasing EPR pair rate due to decreased heralding and purification failure. We apply optimism to the entanglement pumping scheme, ground- and satellite-based EPR generation sources, and current state-of-the-art purification circuits that include several measurement and purification checkpoints. We evaluate performance in view of a number of parameters, including link length, EPR source rate and fidelity;and memory coherence time. We show that while our optimistic protocol increases fidelity, the traditional approach may even decrease fidelity for longer distances. We study the trade-off between rate and fidelity under entanglement-based QKD, and find that optimistic schemes can yield higher rates compared to non-optimistic counterparts, with most advantages seen in scenarios with low initial fidelity and short coherence times. © 2023 IEEE.

Model selection is an essential step when applying machine learning to classification problems. It is typically carried out by the practitioner who strives to identify the most suitable classifier for a given problem. Given the variety of classifiers available and the difficulty in predicting which one will yield the best performance depending on the characteristics of the problem, this is by no means a simple task. Biomedical problems pose a significant challenge in this regard due to their numerous data intrinsic characteristics that are known to impair classification performance. Given that different classifiers perform well for different biomedical problems, combining them into an ensemble would seem practical. However, the practitioner still needs to determine how to combine them. This paper presents an ensemble-based framework that automates the training and combination of different classifiers in order to relieve practitioners of this burden whilst obtaining highly competitive performance. The effectiveness of the proposed framework was evaluated on several biomedical problems from the literature. © 2023 IEEE.

The rapid advancement of 5G Radio Access Network (RAN) architecture is facilitating the construction of 5G networks, marking a significant milestone in telecommunications evolution. Given the complexity of the 5G core architecture, traditional simulation methods are insufficient, necessitating novel approaches. Emulator systems are crucial for creating dynamic, controlled environments that enable exploration of real-world scenarios without physical constraints. SEMU5G, a 5G core emulator, SDN controller, and RAN simulator, utilizes Open5GS implemented in Docker Container for test system flexibility and isolation. Additionally, an SDN controller is integrated to monitor data flows in the User Plane Function (UPF) and gNB simulated by UERANSIM in Mininet-WiFi. This comprehensive integration facilitates effective and flexible real-world exploration, providing a dynamic and controlled test environment for 5G core research. Scenario testing comprises two stages: firstly, a fixed network topology is employed to compare resource usage and confirm successful SEMU5G integration. Secondly, a mobile network topology is utilized to implement a mobile device scenario and compare the Quality of Service (QoS) of SEMU5G with other available emulators. These stages ensure thorough evaluation of SEMU5G's performance and its comparative advantage over existing solutions. © 2024 IEEE.

This study investigates the impact of functional capacitive field grading composites (FCFGC) on reducing electrical stresses in twisted wire pairs and direct bonded copper (DBC) power substrates. FCFGC materials are created by dispersing ferroelectric Barium Titanate (BTO) nanofillers in a Polydimethylsiloxane (PDMS) matrix. Experimental evaluations include determining the permittivity of these composites and conducting tests on partial discharge and surface flashover under high dv/dt square voltage pulses. Results show that incorporating FCFGC leads to a 2.68-fold increase (i.e., 168% increase) in partial discharge inception voltage (PDIV) and a 64.1% increase in surface flashover voltage (SFV) for twisted pairs and DBC substrates, respectively. Furthermore, numerical models are utilized to analyze the electric fields of the twisted pair and power substrates. These models integrate the field-dependent, characterized properties of the composites, offering a deeper understanding of the experimental results. © 2024 IEEE.

A differential pulsed millimeter wave (mm-wave) voltage-controlled oscillator (VCO) is proposed and designed on a 65 nm 1-poly 10-metal (1P10M) CMOS process for radar and imaging applications. The features of VCO and pulsed oscillators are integrated together. The losses offered by the on-chip inductor are compensated with a widely used NMOS cross-coupled pair by providing a sufficient amount of negative resistance-the feature of pulsed RF oscillations achieved by using a PMOS head switch. The controllability of the oscillation frequency is achieved by using tuning transistors. The tuning range of the proposed pulsed RF VCO is 1.9 GHz, from 81.2-83.1 GHz. The input pulse signal provides bias to the PMOS head switch when its amplitude is zero volts. The proposed pulsed RF VCO occupies an area of 175 um × 130 um. The proposed design results in a phase of -87.21 dBc/Hz at 1 MHz offset for the oscillation frequency of 83.1 GHz. The DC power consumption of the design varies from 8.6-11.6 mW. © 2024 IEEE.

Edge computing plays a crucial role in the advancement of Beyond 5G (B5G) and 6G networks. The substantial growth in network traffic and computational requirements necessitates the implementation of multi-access edge computing (MEC) as a viable solution. MEC aims to bring the capabilities of cloud computing closer to end-users by integrating them into the radio access network (RAN). This research introduces an optimal approach to connect mobile users with MEC hosts and access points, effectively distributing radio and computing resources to individual mobile users. The objective is achieved by lowering the total user transmit power while abiding by latency constraints in both the communication and computation phases, using the Grey Wolf Optimization technique (GWO). A comparison to alternative smart techniques demonstrates the effectiveness of the suggested approach © 2024 IEEE.
