This paper introduces a network Management System (NMS) for mobile network services in the area of 5G networks. It offers a structure authorized with Intent-Based networking (IBN). Especially, the NMS supports network intent translator, closed-loop networkcontrol, and network audit system. It is a constructive framework with system factors supporting various features in NMS in terms of network management. The structure of the proposed NMS can make the network management be automatic and efficient in 5G mobile networks. Thus, it can perform effectively various services in the 5G mobile networks, such as the data gathering of internet of Things (IoT) devices, the configuration and management of network slicing, and the quality of Service (QoS) in 5G Vehicle-to-Everything (V2X).

In Model Predictive control (MPC) closed-loop performance heavily depends on the quality of the underlying prediction model, where such a model must be accurate and yet simple. A key feature in modern MPC applications is the potential for online model adaptation to cope with time-varying changes, part-to-part variations, and complex features of the system dynamics not caught by models derived from first principles. In this paper, we propose to use a physics-informed, or gray-box, model that extends the physics-based model with a data-driven component, namely a Recurrent Neural network (RNN). Relying on physics-informed models allows for a rather limited size of the RNN, thereby enhancing online applicability compared to pure black-box models. This work presents a method based on Moving Horizon Estimation (MHE) for simultaneous state estimation and learning of the RNN sub-model, a potentially challenging issue due to limited information available in noisy input-output data and lack of knowledge of the internal state of the RNN. We provide a case study on a quadruple tank benchmark showing how the method can cope with part-to-part variations. Copyright (C) 2024 The Authors.

This paper presents the design of a 4x4 Blass matrix for enabling beamforming operations in a four-element uniform linear antenna array (ULAA) operating at 3.5 GHz, corresponding to the first frequency band reserved for the forthcoming fifth and sixth generation (5G/6G) systems. To obtain a simple and inexpensive device, the proposed feeding network, which provides to the ULAA beam pointing capabilities towards four different directions, is entirely implemented using printed circuit board technology. The design procedure is realized adopting an extended iterative mathematical framework accounting for losses control and providing the pointing angles and the matrix coefficients. The performance of the conceived architecture is numerically investigated through full-wave simulations. The versatility, low losses, and low price of the developed microstrip network makes it suitable for both 5G/6G air/terrestrial femtocell base stations and internet of Things (IoT) cluster-head sensors/actuators.

Sensor data collected from climate stations has been used in various scientific applications and environmental monitoring. Maintaining the data quality is essential to guarantee the reliability and accuracy of science outputs, potentially impacting many critical decision making processes. Existing sensor anomaly detection techniques are mostly designed for general purposes, and may not be suitable for climate sensors which require complex handling of seasonality, spatial relationship and sensor interdependency. Current qualitycontrol process is deficient in climate sensor drift detection, which is a slow degradation of sensor accuracy over time. Recent development of anomaly detection in climate sensor domain is limited, it's often constrained to particular sensor types, and not focused on drift detection. In this paper, we present a new drift-aware time series anomaly detection framework which leverages the spatial-temporal correlation of the climate sensor network and significantly improves climate sensor drift detection capability. Moreover, the proposed semi-supervised learning approach helps to generalise the solution for various types of sensors and anomalies. Our experiments using real-world dataset have demonstrated promising and competitive performance in regards to sensitivity, false alarm control, and computational efficiency suitable for real-time or near-real-time applications.
