In Non-Orthogonal Multiple Access (NOMA) wireless networks, base station broadcasts the aggregated contents to all users, where short-distance users have stronger signals compared with long-distance users. Stronger signal users can decode and subtract other weaker users' signals without interference and thus they can forward packets to weaker users as relay devices for better network utilization. In traditional NOMA, the decoded information is simply subtracted from the superposition coded signal and the devices do not take advantage of the cached content. In this paper, inspired by the use it or lose it concept, we propose an economic auction-based NOMA relay approach. The proposed strategy utilizes Vickrey-Clarke-Groves (VCG) auction theory to make the optimal relay-user matching decision based on utility models for base station and relay devices. Through VCG auction, relay devices obtain their maximum utility and user equipment get a better service. Simulation results illustrate the potential performance gain of NOMA relay forwarding with VCG auction mechanism. © 2023 IEEE.

A multi-objective Scheduling approach for large-scale microservice Critical Notification system applications (SCN-DRL) based on Deep Reinforcement Learning is presented. This paper addresses optimization for three objectives: cloud service cost, cloud resource utilization, and system notification deadline. Recent advances in the deep reinforcement learning field inspired us to research how to build a solution that learns to manage the cloud container's resources directly from experience. SCN-DRL is an example solution that translates the containerized microservice cloud cluster scheduling problem into a learning problem. To the best of our knowledge, this is the first work dealing with multi-optimization objectives for critical microservice notification applications using deep reinforcement learning, where the notification load is variable and depends on the results of the other previously prior processed microservice. Our initial results show that SCNDRL performs better than state-of-The-Art heuristics and adapts to different workload conditions without a noticeable drop in performance. © 2022 IEEE.

In this research, we propose a dual-beam frequency-scanning leaky-wave antenna that utilizes a composite slow-wave waveguide. The composite slow-wave waveguide is created by integrating double-layer symmetrical spoof surface plasmon polaritons structures on both sides of the half-mode substrate integrated waveguide to support a composite slow-wave mode. To achieve the desired dual-beam radiation pattern, periodic circular patches are placed on both sides of the composite slow-wave waveguide. These circular radiation patches are coupled electromagnetically with the slow-wave waveguide. Additionally, a rectangular copper patch is introduced in the antenna design to reduce interference between the two radiation beams. Using simulation, we demonstrate that the proposed leaky-wave antenna achieves continuous beam-scanning within an operating frequency range of 9-11 GHz, with angles of 54° and 55° for the upper and lower beams, respectively. © 2023 IEEE.

Conventional classification approaches for EEG- based emotion recognition cannot often adapt to different domains, such as cross-subject or cross-dataset scenarios, leading to poor performance. To handle this challenge, we introduce a novel fusion method using a combination of multiple domain adaptation techniques to improve the emotional states in EEG datasets via classification accuracy. For this aim, Our proposed approach exploits domain adaptation approaches such as Transfer Component Analysis (TCA), Correlation Alignment (CORAL), Transfer Joint Matching (TJM), Geodesic Flow Kernel (GFK), and Joint Distribution Adaptation (JDA), to enhance the overall classification performance. Later, a new fusion approach called Multiple Domain Adaptation based on a Neuro-Fuzzy Inference System (MDA-NF) is applied to combine the classifiers using proper fuzzy membership functions and deliver maximum separation between classes. The main contribution is by applying the fusion approach using MDA- NF technique, adaptability is sufficiently enhanced. Another advantage is to employ multiple adaptation techniques that improve separation between classes. In experimental test results conducted with cross-subject and cross-dataset scenarios, the MDA-NF approach demonstrates superior performance in terms of accuracy for both the valence and arousal aspects, as observed in two public DEAP and DREAMER datasets. © 2023 IEEE.

Resilient operation of cloud-native applications is a critical requirement to service continuity, and to fostering trust in the cloud paradigm. So far, service meshes have been offering resiliency to a subset of failures. But, they fall short in achieving idempotency for HTTP POST requests. In fact, their current resiliency measures may escalate the impact of a POST request failure. Besides, the current tight control over failures - within central clouds - is being threatened by the growing distribution of applications across heterogeneous clouds. Namely, in moving towards a fog-native paradigm of applications. This renders achieving both idempotency and request satisfaction for POST microservices a non-trivial challenge. To address this challenge, we propose a novel, two-pattern, resiliency solution: Idempotency and Completer. The first is an idempotency management system that enables safe retries, following transient network/infrastructure failure. While the second is a FaaS-based completer system that enables automated resolution of microservice functional failures. This is realised through systematic integration and application of developer-defined error solvers. The proposed solution has been implemented as a fog-native service, and integrated over example service mesh Consul. The solution is evaluated experimentally, and results show considerable improvement in user satisfaction, including 100% request completion rate. The results further illustrate the scalability of the solution and benefit in closing the current gap in service mesh systems.

Nanocrystalline materials, known for their excellent magnetic properties, are widely used in the design of inductors and transformers, yet their application has been primarily limited to low-frequency scenarios due to their low resonance frequency. This paper introduces an innovative 2D nanocrystalline inductor design that not only capitalizes on the excellent magnetic characteristics of nanocrystalline materials but also effectively increases the resonance frequency to above 10 MHz, enabling the use of nanocrystalline materials in high-frequency power electronics. This design is not only suitable for mass production but also breakthrough in frequency limitations of nanocrystalline Materials. Experimental and simulation results confirm the superiority of the proposed design in enhancing high-frequency impedance, increasing high-frequency insertion loss, exhibiting improvements in EMI conduction frequency range (150 kHz - 30 MHz). The performance of the filter with the proposed 2D inductor is superior to the performance of EMI filters using other inductors within high frequency range, marking a significant breakthrough in magnetic device design. © 2024 IEEE.

Traditionally, conical ridge horn antennas are used for feeding large reflectors, but they can cause grating lobes in arrays. This paper introduces a compact Vivaldi antenna for monopulse radar, featuring a planar feed structure that offers a wider bandwidth and simplifies manufacturing. The innovative design of the Vivaldi antenna incorporates strategically placed grooves and a circular dielectric lens to enhance gain and reduce sidelobe levels. Operating from 6 GHz to 18 GHz with proper impedance matching, the antenna is 23 mm wide ($0.9 \lambda$ at 12 GHz), making it over 66% smaller than traditional designs. The antennas are angled in $2 \times 2$ array configuration to overlap, with a center-to-center spacing of $11.3 \mathrm{~mm}(0.68 \lambda$ at 18 GHz), ensuring that no grating lobes are present across the entire bandwidth. This innovative antenna effectively feeds an elliptical reflector, providing high gain, broadband capabilities, and significant null depth, ensuring accurate and efficient performance in monopulse radar applications.

Both the academic and industry begin the early research on the network architectures of the 6th generation (6G) mobile communication system, which integrates the satellite networks for ubiquitous access. However, the 5th generation non-terrestrial network (5G NTN) architecture and the existing integrated network architectures do not consider the specific trimming schemes of network element functions placed on-orbit, which may cause the waste of resources. Therefore, we propose a microservice-based satellite-terrestrial integrated network architecture, where the access network (AN) and the user plane function (UPF) are servized, to achieve deeper integration between the AN and the core network (CN). Based on the new network architecture, a basic principle of network element function trimming is proposed, and two examples of UPF function trimming are given in the typical scenarios with satellite networks. The function trimming results have exhibited that the UPF effectively reduces the number of functions equipped on the satellite by probably 42 % and 63 % in two typical scenarios, respectively, which saves the satellite resources. © 2023 IEEE.
