This research addresses one of the major problems in agriculture that farmers are currently facing: birds causing significant crop damage in agricultural fields. To reduce this damage, a person’s presence is often required in the farm field to repel the birds. To eliminate this need and automate the repellent system, the project aims to develop a bird repellent device using computer vision techniques to detect and repel birds from fields. Existing work lags behind in using effective algorithms and developing hardware. Object detection algorithms like the Haar Cascade Classifier and YOLOv8 are used; YOLOv8 is a powerful object detection algorithm, and it is chosen as the primary algorithm for its accuracy and speed in detecting birds. A hardware device is developed using a Raspberry Pi with a Pi camera and a Bluetooth speaker. Upon detecting birds in the farm fields through the Pi camera, distress calls are produced through the Bluetooth speakers to repel the birds.

Fruit variety classification is a crucial aspect in agricultural processes and supply chain management, influencing market competitiveness, and consumer satisfaction. This paper provides a comprehensive review of various fruit variety classification techniques utilizing machine learning (ML) methodologies, highlighting the motivations driving research in this domain and the challenges that researchers and practitioner’s encounter. The capabilities of ML algorithms and deep learning (DL) models have facilitated significant advancements in fruit classification accuracy. Motivated by the growing demand globally for fruits and their varieties and the need to optimize resources utilized in agriculture, researchers have focused on developing ML-driven classification systems capable of automating fruit sorting, grading, maturity estimation, and quality control processes. DL particularly has ability to learn complex representations from images, among which the primary architecture is the convolutional neural network (CNN) for applications related to image classification. Based on the extensive literature survey conducted, its observed that utilization of CNN for fruit variety classification has immensely increased generating outstanding results using “from-scratch” or “pretrained” model for transfer learning, however it often struggles with limited datasets, leading to poor generalization, and difficulty in handling variations in fruit appearance due to lighting, orientation, or ripeness. Besides this, the paper presents frameworks, model design, and one practical application on the use of CNN for fruit variety classification.

An automated damage detection method based on deep learning for wind turbine blades uses the YOLOv5 framework, which is object detection that is quite fast and relatively accurate for detecting objects and localization instances of damage in images. Source data has been a curated collection dataset of wind turbine images with annotated regions of damage; thus, a model was trained from Roboflow. This uses transfer learning in which the model is started with pre-trained YOLOv5s weights and further fine-tunes it over the specific dataset. It also fits well into the nature of the data-set including the number of classes of damage. The training process, therefore, is optimizing the model parameters to achieve the minimization of differences between predicted bounding boxes and the available ground-truth annotations. Standard metrics for object detection are used in the evaluation of the model: precision, recall, mean Average Precision (mAP), and F1-score. Qualitative assessment is also carried through as a visual check on the predictions that the model would produce on unseen images, validating its use in real conditions. It contributes to developing an automated and efficient system concerning structural health monitoring of wind turbines and enables maintenance at the appropriate time, thus decreasing down times.

Emerging AR-VR applications execute complex heterogeneous workloads, mixing Deep-Learning(DL) and Digital-Signal-Processing(DSP) tasks, on SoCs embedded in the frame of eyeglasses, with implied tight power and area constraints, especially in the case of AR. We propose ArchiMEDES, an open-source heterogeneous-SoC platform with a programmable cluster of RISC-V cores coupled with a configurable DNN engine (NEureka) targeting AR/VR workloads. ArchiMEDES features a low-overhead Heterogeneous Cluster Interconnect(HCI) to enable fast RISC-V/NEureka cooperation on a shared tightly coupled data memory (TCDM). We show post-layout results targeting 22nm technology; ArchiMEDES shows a peak combined performance of up to 1.19 TOPS and an efficiency of up to 10.6 TOPS/W. Hardware-Software cooperation in ArchiMEDES enables a 5.5× speedup in an AR-VR gaze tracking case study, compared to a non-cooperative single-RISC-V + Accelerator system.

The piezoelectric energy harvesting system functions as an environmentally powered system which converts mechanical vibrations in the environment into electrical power. The energy will subsequently power mobile charging systems. Piezoelectric crystals form an integral part of the system because mechanical stress causes them to produce output voltages. The system uses a microcontroller to monitor continuous voltage and current readings from the piezoelectric crystal before the IoT platform receives this data for remote monitoring. The data transmission system ensures both the accuracy and top quality standards of transmitted information. A DC-DC converter functions to prepare the collected energy. The system accepts steady input while creating outputs which have constant and variable components. The constant input guides effective power supply systems with voltage stabilizers without any changes in input levels. The rechargeable battery-based charger functions as the main power supply for mobile device charging operations. The application collects smaller power volumes through this system which makes it suitable for remote sites unable to connect to standard power distribution networks. Users now have convenient access to view real-time data about energy generation and storage thanks to the Internet of Things (IoT) while their system delivers an optimal working condition. This power system design featuring piezoelectric energy harvesting power moulding and supercapacitor caching leads to an environment friendly solution for mobile equipment energy needs in regions with restricted power supplies.
