In the recent past, data-centric solutions have been developed to address crop choice issues, low yields and soil management. The proposed work in this paper is a web-based application, referred to as Farm Fusion designed to help the farmers for the selection of the best crops to be cultivated according to specific site characteristic. This system utilizes the following machine learning algorithms like Support Vector Machine (SVM), K-Nearest Neighbor (KNN), Random Forest, Gaussian Naive Bayes (GNB) and gradient boosting models LightGBM, XGBoost, and CatBoost. Before suggesting the appropriate crops, the system uses an Ensemble model that integrates these algorithms. The input soil nutrient parameters included in this system are phosphorus, potassium, nitrogen while the input environmental parameters include pH, temperature, rainfall and humidity. It is a web application that uses the flask framework which is integrated with pre-trained model to recommend right crop for the farm field. This system will assist in the process of decision making process, provide sustainability and improve crop yield.

This paper explores the dynamics of Human-Robot Interaction (HRI) in public spaces, focusing on how humanoid robots engage with human crowds in the competitive RoboCup Soccer environment. We examine the role of spectatorship, where emotional engagement arises through indirect observation of engineering-driven competition, drawing parallels between human soccer and robot sports. The potential for autonomous systems to elicit collective emotions and systematically study such experiences is investigated. Using the Autonomy Levels for Unmanned systems (ALFUS) framework, we assess RoboCup soccer robots' autonomy in terms of mission complexity (MC), environmental complexity (EC), and external system independence (ESI). Additionally, the Autonomy and technology Readiness Assessment (ATRA) method supports gradual capability enhancement, providing a roadmap to higher autonomy. Based on this established methodology, we introduce the Robot-Crowd Interaction Framework (R-CIF), a novel conceptual framework defining the roles of actors involved, to connect theoretical insights with real-world applications. This work highlights the significance of crowd affectivity in robotic sports to boost public engagement and proposes directions for future research on collective emotional dynamics in HRI.

Radar antenna scanning patterns include mechanical scanning, one-dimensional phased array scanning, and two-dimensional phased array scanning. When facing radar emitter whose radar type is unknown, the antenna scanning pattern is a critical factor in assessing the threat level. Traditional identification methods are based on expert features and often fail to adequately consider factors such as amplitude-frequency response and measurement errors. This paper employs short-term interpolation for noise reduction and long-term LSTM for classification and recognition. Experiments show that this method has good accuracy in identifying pulse sequences under conditions of frequency variation and measurement errors, making it valuable for practical applications.

The phase retrieval (PR) problem involves recovering a signal from amplitude-only measurements and has been extensively studied in various physical measurement and signal processing systems. Recently, there has been increasing interest in the quantized phase retrieval (QPR) problem, where the observed amplitude is quantized to binary values. The existing studies have focused on the noiseless case. In this paper, we address a robust QPR problem that accounts for both quantization and noise. We formulate the robust QPR problem using maximum-likelihood estimation (MLE), which results in a non-convex and challenging optimization problem due to the complexity of its likelihood function. To obtain a high-quality solution, we develop an expectation-maximization (EM) algorithm combined with the Wirtinger flow, allowing us to convert the problem into a more manageable form at each iteration. Our method is implemented on both randomly generated synthetic data and image reconstruction tasks. The results demonstrate that our approach significantly enhances signal recovery performance under the combined effects of quantization and noise. Additionally, the proposed method exhibits better runtime efficiency compared to existing approaches.

Global water resource management, particularly for large lakes, faces significant challenges in balancing ecological, economic, and flood control needs. Current methods struggle to address the diverse demands of stakeholders due to the complex hydrological and environmental factors involved. This paper proposes a solution using a multi-objective optimization model combined with dynamic feedback control. By applying hierarchical analysis (AHP), we assign stakeholder demand weights and develop a real-time water level prediction model using particle swarm optimization (PSO) with a shrinkage factor. The system also incorporates multidimensional feedback control via a spatio-temporal dynamic network to regulate water levels in real-time based on predictive data. Validation using the Great Lakes’ hydrological data from 2000 to 2022 shows the model’s effectiveness in handling environmental changes and maintaining water stability. The model proves to be a robust and practical tool for large-scale water resource management.

Ship name identification carries identity information. Ship data can be collected quickly by identifying the identification characters in the ship image. However, due to many factors such as light pollution, large tilt angle and environmental interference in ship image, ordinary Optical Character Recognition is difficult to process directly. Based on the self-built ship image dataset, this paper completes the preprocessing of the target image by means of gray levelization, straight square equalization and noise removal. Afterwards, the improved character region positioning algorithm and the fusion neural network model are used to realize the extraction of ship number characters. The recognition accuracy of ship number character can reach 92%. At the same time, referring to the method of highway traffic management, this identification method is used as the core function to design the ship identification system.

To improve collision avoidance and stability of intelligent driving vehicles in emergencies, a control method considering road adhesion is proposed. First, a Kalman filter estimates the road adhesion coefficient in real time based on tire-road interaction. Then, a lateral and longitudinal controller is designed to track the optimal collision avoidance trajectory by applying brakes and generating the optimal steering angle. The controller includes constraints for low-adhesion surfaces to reduce instability. Finally, a joint simulation platform using Prescan, CarSim, and Simulink validates the system. Results show that, compared with the other two control strategies, the designed control strategy can reduce the vehicle's peak sideslip angle by 7.14% and 32.08% respectively in emergency situations, thus enhancing the vehicle's collision avoidance ability and driving stability.

Detecting objects such as vehicles, buildings, pedestrians, and road signs is indispensable to advancing the concept of autonomous and self-driving cars. Furthermore, an autonomous vehicle (AV) must accurately detect its surrounding environment to operate reliably. Most object detection (OD) techniques perform adequately under typical weather conditions, including cloudy or sunny days. However, their efficiency decreases significantly when exposed to Adverse Weather Conditions (AWCs), including days with sandstorm, rain, fog or snow. Complex and computationally costly models are required to achieve high accuracy rates. In this study, we present an improved OD system in AWCs for autonomous vehicles (AVs) using the single-stage deep learning (DL) algorithm YOLO (You Only Look Once) version 10. To evaluate our system, Vehicle Detection in Adverse Weather Nature (DAWN) dataset is used. It comprises real-world images captured under various types of AWCs. The experimental findings confirm that the suggested method is effective and surpasses state-of-the-art OD approaches under AWCs.
