Smart antennas are now widely expended in transmission systems due to their vital plusses. To boost the performance of smart antenna operation, it is crucial to design an efficient beamforming pattern based on specific antenna parameters. Due to their numerous benefits, smart antennas are now often utilized in communication systems. It is essential to create a successful beamforming pattern based on certain antenna parameters with the objective of improvement in the performance of smart antenna operation. Beamforming strategies utilizing a combination of soft computing techniques were proposed in earlier works. These methods, however, did not take signal Direction of Arrival (DOA) precision into account. While determining the beamforming pattern for smart antennas, this research addresses the DOA issue. The researchers use a variety of techniques and conduct a comparison analysis to determine an exact DOA estimate. The authors proposed a method that shows an optimal result after resolving the existing problems for estimating the DOA with precision. In comparison to the traditional DOA pattern, this innovation produces a more accurate DOA pattern with reduced undesired side lobes. The researchers derive the antenna beamforming pattern in accordance with the necessary direction of angles using the predicted DOA pattern. The experimental results demonstrated that the proposed beamforming technology performs better than earlier techniques. In this work, advancement in beamforming precision can lead to better communication system performance and overall efficiency of smart antennas.

With the increasing water shortage and climatic uncertainty, creative strategies for effective water management in agriculture are necessary. This research investigates the integration of Artificial Intelligence (AI), particularly Artificial Neural Networks (ANN), with solar-powered Internet of Things (IoT) networks to enhance water utilization in agricultural activities. The proposed system facilitates accurate irrigation scheduling using real-time data from soil moisture sensors, meteorological stations, and crop health monitoring devices. The ANN model analyses this data to predict ideal irrigation schedules and volumes, minimizing water waste while improving crop yields. The solar-powered IoT framework provides sustainability and reduces dependence on traditional energy sources. Field trials indicate that the AI-enhanced system may promote water saving by as much as 30% relative to traditional irrigation techniques. Moreover, using AI enables adaptive learning, enabling the system to enhance its irrigation tactics using historical and real-time data. This novel method conserves water resources and fosters sustainable agriculture practices, coinciding with global initiatives to address water shortages and assure food security. The findings underscore the potential of technology-based solutions to revolutionize agricultural water management for a sustainable future.

Performing field testing of drone missions requires the structured definition of field tests that can be adapted to changing environmental conditions. However, traditional field test checklists on paper require the tester to manually adapt tasks to emerging and changing test conditions. Further, the scattered, heterogeneous documentation on (electronic) paper is hard to integrate and validate - once field tests are completed - for test data analysis. Field test managers, testers, and analysts require an agile field test information system that provides capabilities for (i) providing efficient guidance to field testers on tasks adapted to the field test mission state; and (ii) creating structured field test documentation for advanced analysis of results and causes of risky effects. This paper introduces the Agile Field Test (AFT) approach for behavior-driven test specification and derivation of role-specific information systems for agile guidance on and documentation of field test tasks. We evaluated the effectiveness of the AFT approach with a real-world multi-drone water rescue mission. The study results indicate AFT to be effective for representing and validating field test task specifications and the concepts required for field test documentation as a foundation for test result analysis.

Investigations of kinematic and dynamic models of tractor-trailer systems have historically been performed for stability analysis or state estimation. In this work, we present and evaluate kinematic and dynamic tractor-trailer models for model predictive control (MPC). We show in open-loop simulations that a kinematic and a dynamic model are equivalent at low speeds and short discretization time steps. A zero speed singularity and stiff dynamics prevents the usage of the dynamic model in control design, where discretization time steps are longer. A method of discretization is proposed to resolve the low speed feasibility of the dynamic model. In closed-loop simulations, the real-time applicability of the kinematic and dynamic models in a nonlinear MPC is verified.

The performance limitations of conventional software-based Intrusion Detection systems (IDSs) have paved the way for the emergence of hardware-oriented approaches. These approaches harness the power of Machine Learning (ML) algorithms applied to processors’ hardware-related data, thereby enhancing the overall system’s security and efficiency. However, ensuring the dependability of ML models’ decisions is crucial, yet this aspect has been largely overlooked in previous studies. In this paper, we delve into the reliability of machine learning algorithms within hardware-oriented intrusion detection systems, focusing specifically on malware detection. Our investigation aims to bridge the existing gap by shedding light on the tradeoffs between performance vs. reliability and robustness levels exhibited by ML models in intrusion detection systems. We conduct a thorough evaluation of ML algorithms in hardware-oriented IDSs, considering factors such as training data size, number of hardware events used, and internal data separability (malware stealthiness). Additionally, we incorporate an effective model observer module to assess prediction probabilities in real-time; thereby, employing a threshold to determine the ML model’s confidence for enhanced reliable intrusion detection.
