This paper proposes an observer-based formation tracking control approach for multi-vehicle systems with second-order motion dynamics, assuming that vehicles' relative or global position and velocity measurements are unavailable. It is assumed that all vehicles are equipped with sensors capable of sensing the bearings relative to neighboring vehicles and only one leader vehicle has access to its global position. Each vehicle estimates its absolute position and velocity using relative bearing measurements and the estimates of neighboring vehicles received over a communication network. A distributed observer-based controller is designed, relying only on bearing and acceleration measurements. This work further explores the concept of the Bearing Persistently Exciting (BPE) formation by proposing new algorithms for bearing-based localization and state estimation of second-order systems in centralized and decentralized manners. It also examines conditions on the desired formation to guarantee the exponential stability of distributed observer-based formation tracking controllers. In support of our theoretical results, some simulation results are presented to illustrate the performance of the proposed observers as well as the observer-based tracking controllers. © 2024 IEEE.

Caesium quantum clocks, pivotal in defining the SI second since the 13th General Conference on Weights and Measures in 1967, rely on intricate electronic and optical systems for precise timekeeping. Ensuring the accuracy of these systems requires monitoring and controlling environmental parameters like temperature and humidity, as fluctuations can lead to errors and potential damage. This paper presents the development of a diagnostic system using an Arduino UNO connected to a DHT11 sensor and ESP8266 Wi-Fi module to continuously monitor and transmit environmental data. The collected data is analyzed to maintain optimal operating conditions for the quantum clock infrastructure. Implementations using the IoT platform ThingSpeak demonstrate the system's capability for real-time data visualization and analysis. Statistical analysis of sampled data over a 30-minute interval shows a mean temperature of 23.45°C and a mean humidity of 51.30%, with a strong correlation coefficient of 0.99 between the two parameters. A linear regression analysis further supports this relationship, indicating that for every 1°C increase in temperature, humidity increases by approximately 5.11%. This diagnostic system not only ensures environmental stability but also aids in preventing inaccuracies in timekeeping, enhancing the reliability of caesium quantum clocks. © 2024 IEEE.

We present advancements in novel rf signal processing techniques which combine the benefits of high-Q, high-linearity, and large dynamic range of acoustic wave devices with the tunability and nonlinear functionality of spin wave devices. The design and implementation of two such magneto-acoustic devices, a tunable high-overtone bulk acoustic resonator (HBAR) and a rf signal correlator are discussed. The devices are implemented on yttrium iron garnet (YIG), chosen for its low damping of both spin and acoustic waves and magnetoelastic properties for coupling them. © 2023 IEEE.

The direct connection of the jaw to the brain allows it to retain its motor and sensory capabilities even after severe spinal cord injuries. As such, it can be an accessible means of providing inputs for people with paralysis to manipulate their environment. This paper explores the potential for using the jaw, specifically the mandible, as an alternative input to human-machine interface systems. Two tests were developed to test the mandible's ability to respond to visual stimuli. First, a visual response time test to measure the precision and accuracy of user input through a mandible-actuated button. Second, a choice response test to observe coordination between the mandible and a *** results show that the mean response time of mandible inputs is 8.3% slower than the corresponding mean response time of performing the same task with a thumb. The delay in response after making a decision is statistically insignificant between the mandible-and finger-actuated inputs with the mandible being 2.67% *** on these results, the increase in response time while using the mandibular input is minimal for new users. Coordination is feasible in tasks involving both the mandible and thumb. Extensive training with a made-to-fit device has the potential to enable a visual response time equivalent to the fingers in more complex tasks. The mandible is a viable option for accessible HMI for discreet inputs. Further testing into continuous input is needed to explore the mandible's potential as an input for body augments. © 2022 IEEE.

With the advent of rigorous membrane research and development in the middle of the 20th century, more wastewater plants started incorporating Membrane BioReactors (MBR) in their design. However, being a membrane system, the MBR is subject to fouling which may lead to maintenance and cleaning costs. In this paper, a fouling monitoring and prediction tool has been designed in MATLAB\Simulink. The model takes states related to membrane fouling, and calculates the membrane total resistance based on deterministic and stochastic models. The tool is capable of predicting future transmembrane pressure (TMP) cycles based on older TMP performance via an artificial neural network algorithm. TMP data have been synthetically generated from a validated mathematical model. Finally, an artificial neural network controller is implemented to control temperature and Mixed Liquor Suspended Solids (MLSS) around their desired setpoints. The controller is able to minimize disturbances in both states in a narrow band around their desired setpoints.

DFRC Signaling Strategies based on MIMO Beampattern Invariance

IEEE Transactions on Communications 2025年

作者： Mazahir, Sana Ahmed, Sajid Alouini, Mohamed-Slim King Abdullah University of Science and Technology CEMSE Division Department of Electrical and Computer Engineering Thuwal23955 Saudi Arabia

The Dual-function radar communication (DFRC) design aims to exploit the tractability and reusability of both radar and communication systems' components, parameters, and spectrum to achieve an integrated system. In this work, we propose a novel DFRC signal design by leveraging the phenomenon of the MIMO beampattern invariance, which was comprehensively explored in our previous work [1]. It is demonstrated that the flexibility afforded by this beampattern invariance can be used to construct an integrated waveform while maintaining the required beam. A beampattern-preserving unitary transformation of the MIMO weight matrix is proposed to realize a desired information-bearing symbol at the communication receiver. The proposed method has the following promising features: 1) low-complexity, closed-form solution for the transmitted signals;2) flexibility of modulation scheme;3) independence from the type of orthonormal MIMO waveforms;4) independence from the beampattern design;5) adaptability for multi-target and multi-user scenarios. Using this generic signal design method, a number of modulation schemes are implemented. Furthermore, the impact of this operation on the estimation accuracy of the target parameters is analyzed by computing their respective Cramer-Rao Lower Bounds (CRLBs). Simulation results show that modulation schemes yielding a range of symbol error rate (SER) performances can be implemented while keeping the radar parameter estimation unaffected. © 2025 IEEE.

This work aims to leverage the existing fifth generation (5G) new radio (NR) synchronization signal (SS) burst for network-side integrated sensing and communications (ISAC). A novel density-based clustering of applications with noise (DBSCAN)-based multi target detection algorithm is proposed. Furthermore, utilizing the beam sweeping nature of the SS burst, joint velocity, angle, and range (JVAR) estimation algorithms are proposed. Simulation results show that the proposed detection algorithm can reach an overall average detection accuracy of around 0.98 for different number of targets scenarios. On the other hand, the JVAR estimation accuracy are dependent on the individual radar resolution of velocity, angle and range. © 2025 IEEE.

Reasoning over knowledge bases such as Semantic Web ontologies enables the discovery of new facts from existing knowledge. Knowledge-enhanced machine learning has motivated the development of neuro-symbolic reasoners, which enable faster but approximate computation of new facts or entailments. Neuro-symbolic methods generate vector representations (embeddings) of entities in a knowledge base. We analyze some ontology embedding methods, by implementing them as neuro-symbolic reasoners and evaluating their predictive performance on the datasets and tasks provided by the Semantic Reasoning Evaluation Challenge 2023. We explore two types of embedding methods: graph-based and model-theoretic. Regarding graph-based embeddings, we evaluated the impact of different combinations of graph representation of ontologies with knowledge graph embedding methods. For model-theoretic embeddings, which create models for theories, we evaluate the impact of using several models, enabling approximate semantic entailment. © 2023 CEUR-WS. All rights reserved.
