Smart Antenna Array Design with Reinforcement Learning-Based Beam Steering
Smart antenna arrays have emerged as a cornerstone technology for fifth-generation (5G) and beyond wireless communication systems, enabling adaptive beamforming, spatial multiplexing, and interference suppression. Conventional beam steering methods relying on exhaustive codebook search or model-based optimization suffer from high computational overhead and limited adaptability to dynamic channel conditions. This paper presents a comprehensive survey and a novel framework integrating Reinforcement Learning (RL)—specifically Deep Q-Networks (DQN) and Proximal Policy Optimization (PPO)—with phased antenna array architectures for intelligent, real-time beam steering. The proposed approach models the beam selection problem as a Markov Decision Process (MDP) and trains an RL agent to maximize long-term spectral efficiency while minimizing beam misalignment and tracking latency. Simulation results demonstrate that the RL-based approach achieves up to 97.3% beam accuracy and 23% throughput gain over conventional codebook-based methods in highly mobile multipath environments.

Hardware-Software Co-Design for Low-Latency Object Detection in Autonomous Drones
Autonomous aerial vehicles increasingly rely on real-time visual perception for navigation, obstacle avoidance, surveillance, and inspection tasks. Object detection is the cornerstone of this perception pipeline, yet the strict size, weight, and power (SWaP) constraints of drones, combined with the sub-30-millisecond latency budgets demanded by high-speed flight, make conventional software-only deployment of deep convolutional detectors impractical. This paper presents a hardware-software co-design framework for low-latency object detection on autonomous drones. We review the evolution of lightweight detection architectures and edge accelerator platforms, propose a heterogeneous system-on-chip (SoC) architecture that combines a neural processing unit (NPU), a field-programmable gate array (FPGA) pre/post-processing pipeline, and general-purpose cores, and describe a closed-loop co-optimization methodology spanning network architecture search, quantization, pruning, dataflow scheduling, and memory hierarchy configuration. We evaluate the proposed framework on a representative aerial object detection benchmark using five hardware targets, demonstrating that the co-designed configuration achieves an end-to-end latency of 6.8 ms per frame (147 frames per second), a 14x speed-up over an embedded ARM CPU baseline, while retaining 97% of the mean average precision (mAP) of the floating-point reference model and reducing energy per inference by more than 20x relative to a discrete mobile GPU. The results confirm that jointly optimizing model structure and accelerator architecture, rather than treating either in isolation, is essential to meeting the latency, accuracy, and energy requirements of real-time drone perception.

Smart Waste Sorter-Automatic Waste Segregation System.
Today, the rapid increase in the population and the urban development has led to an increase in the level of solid wastes in India. Managing this waste efficiently has now become a major challenge for the modern societies. One of the main problem in waste management is the lack of segregation at the source. This leads to environmental pollution, health risks and inefficient recycling process. To overcome such issues, this project presents an Automated Waste classification and monitoring system powered by IoT. It automatically separates waste into 3 categories that is wet, dry and metallic waste. The system uses ESP32 microcontroller with sensors such as IR sensor, Raindrop sensor, Proximity sensor. A stepper motor is used to move the position of the bins, while a servo motor is used to control the waste inlet flap. This automated system reduces the manual effort required for segregation and improves waste management efficiency, making it suitable for homes, campuses as well in public areas.

Hybrid Machine Learning Models for Fault Detection in 5G Base Station Hardware
The rapid deployment of fifth-generation (5G) wireless communication networks has introduced complex base station architectures consisting of advanced radio units, massive MIMO antennas, power amplifiers, remote radio heads, and edge computing modules. These components operate under demanding conditions, making fault detection a critical requirement for maintaining network reliability and quality of service (QoS). Traditional fault detection methods rely on threshold-based monitoring and manual inspection, which are often inadequate for identifying complex hardware failures in real time. This paper presents a comprehensive study of hybrid machine learning (ML) models for fault detection in 5G base station hardware. The proposed approach combines supervised and unsupervised learning techniques to enhance detection accuracy while minimizing false alarms. Experimental analysis demonstrates that hybrid models outperform conventional machine learning algorithms in detecting hardware anomalies such as amplifier degradation, antenna faults, overheating, and power supply failures. The study highlights the potential of artificial intelligence-driven predictive maintenance in next-generation telecommunications infrastructure.

AI-Driven Fault Detection and Power Optimization in VLSI Circuits Using Machine Learning Techniques
The proposed FPGA-based architecture was conceptually evaluated against conventional CPU and GPU platforms across three key metrics: power consumption, inference throughput, and energy efficiency.
FPGAs demonstrate significantly lower power consumption compared to GPUs while maintaining competitive inference throughput suitable for real-time edge applications. The architecture achieves superior performance-per-watt, making it highly suitable for resource-constrained embedded environments such as IoT devices, autonomous systems, and smart healthcare applications.
Dynamic voltage-frequency scaling further reduces power consumption during low-workload periods, while quantization and pruning techniques maintain model accuracy within acceptable bounds for edge deployment.

Deep Learning-Based Crop Disease Detection Using Convolutional Neural Networks: A MultiCrop Analysis
Agriculture plays a fundamental role in sustaining human civilization; however, crop diseases continue to pose a major threat to global food security. Early and accurate detection of plant diseases is essential for reducing crop losses and enhancing agricultural productivity, yet traditional disease identification methods rely heavily on manual inspection by agricultural experts, making the process time-consuming, expensive, and impractical for large-scale farming. Recent advances in deep learning, particularly Convolutional Neural Networks (CNNs), have shown significant potential in automating visual recognition tasks, including plant disease classification from leaf images. This paper presents a CNN-based approach for the automated detection of diseases across multiple crop varieties, including rice, wheat, tomato, and potato. The proposed model is trained and evaluated using the publicly available PlantVillage dataset, which contains thousands of labeled images of healthy and diseased plant leaves. To improve model generalization and minimize overfitting, data augmentation techniques such as rotation, flipping, and zooming are employed. Furthermore, the proposed CNN architecture is benchmarked against well-established models, including VGG16, ResNet50, and MobileNetV2. Experimental results indicate that the proposed model achieves a classification accuracy of 97.4%, outperforming several baseline architectures while maintaining computational efficiency. These findings highlight the strong potential of CNN-based automated disease detection systems for real-world applications in precision agriculture and smart farming environments.
