Detection and Removal of Assymmetrical Skin Lesions Using DU-Net for Patch Extraction
This study presents DSeg-net, a novel method for accurately identifying and removingpigmented skin lesions from dermoscopic images, crucial for timely diagnosis and managementof melanoma. DSeg-net combines deep convolutional neural networks, particularly YOLOv5, forpatch detection, asymmetrical patch contouring for edge preservation, and clustering techniquesfor patch extraction. Additionally, it employs De Trop Noise Exclusion with in-painting toeliminate hair from challenging dataset images. The method involves rigorous annotation of skinimages with lesions of varying sizes and shapes using rectangle bounding, followed by fine-tuning YOLOv5 hyperparameters for high-confidence multiple lesion detection. Despitecomplex textures and unclear boundaries, DSeg-net consistently detects and labels patches,accurately segmenting areas of skin pathology. Evaluation on various datasets demonstrates thatthe proposed segmentation techniques achieve an overall average accuracy of approximately92% to 94%
Transfer Learning Using Teachable Machine For Classification Of Glassware In Chemistry Lab
Image classification is an important use case of deep learning algorithms. Convolution Nural networks, CNNs, have evolved to an extent where pretrained models can be used to train new models. The technique used for this type of model building activity is called as Transfer lerning. We have developed an image classification model using transfer lerning to classify lab glassware used in Chemistry lab. This model can be used for training purpose for the students in high schools who are not much aware about the practical implementation of laboratory experiments. We have used subset of Labpics dataset developed by Eppel et.al. We have used teachable machine as a platform to build this model with very limited computational resource. With transfer learning mechanism used by teachable machine platform we were able to achieve ~83% accurate image classification mode
Deep learning models for stock prediction on diverse datasets
Market forecasting has attracted the interest of investors all over the world. The investors are looking for an accurate and reliable forecasting model that can fully embrace the extremely volatile and nonlinear market behavior. It is now possible to design effective stock price prediction algorithms due to the abundance of data, the quick advancement of AI and machine learning techniques, and the machine's increased computational capability. Deep learning algorithms are particularly successful in modelling market volatility. To forecast the closing prices of three stocks: Apple (AAPL), Google (GOOG), and Amazon (AMZN), Convolutional Neural Network (CNN) and Long-Short Term Memory (LSTM) are implemented and compared. The stock data was obtained from yahoo finance for one year, three years and five years. The Root Mean Square Error (RMSE) metric and loss are employed for evaluating the model’s performance
Self-Governing Feedback Network (SGFN) Based Super Resolution for bean leaf disease detection
Crop loss caused by diseases that result from a range of insects, bacteria, viruses, and fungi has been a severe concern for generations that demands global attention. As a result, diagnosing crop diseases as soon as feasible can dramatically reduce production loss and enhance monetary value. The Self-governing Feedback Network (SGFN) model is suggested in this paper for producing Super Resolution images from low-resolution bean leaf images and recognizing disease. On the bean leaf dataset, the proposed SGFN model is tested for super-resolution factors 2, 4, and 6. PSNRs of 31.27, 35.653, and 37.721 are achieved for super-resolution factors 2, 4, and 6, respectively, with classification accuracies of 99.54, 98.73, and 97.64
Role of bio-fertilizers towards sustainable agricultural development: A review
As bioinoculants, numerous eco-friendly microorganisms with a wide range of products are regularly utilised to improve the soil's potential and provide the host plant with the nutrients it requires. The inorganic chemical-based fertilisers employed in the soil management practises are a serious threat to both human health and the environment. Biofertilizers are alternatives that are used in sustainable agriculture to increase soil fertility and crop productivity. The use of beneficial microorganisms as bio-fertilizers has become crucial in the agricultural sector due to its potential impact on food safety and sustainable crop production. The numerous bacteria used in bioinoculant formulations, the carrier materials used, and the applications of biofertilizers are the main subjects of this paper. In especially in appropriate farming, bio-fertilizers are essential for maintaining soil fertility over the long term and crop production sustainability
Design and Fabrication of Earth Auger with trolley
The purpose of this project is to design and fabricate an earth auger to overcome limitations on the existing earth augers. The earth auger is designed by introducing the trolley system. The project will be successful in providing the earth auger which is operator friendly and can be transported from one place to another by the single operator. The simplified mechanisms are implemented in the project including the winches and pulley systems for the feed and movement of the drill bit. The clamping systems are introducing to increase the stability and to decrease the vibrations which keeps the operator to be in a distance during the operations for the purpose of safety. Therefore, this project is made to reduce the fault and to improve the safety measures as well as the usability

Edible Biopolymers from Marine Algae used as an Alternate Packaging material: A Review on their characteristics and properties
Food packaging is estimated to account for two-thirds of all plastic waste. As a result, it is crucial to discover alternative packaging materials that are both environmentally friendly and safe for human health. Marine algae are becoming more well-known and in demand as cutting-edge resources for producing biopolymers like proteins and polysaccharides. Because of their biocompatibility, biodegradability, and lack of toxicity, biopolymers have been suggested as potential sources for food packaging materials. Numerous research has thoroughly examined the extraction, separation, and use of marine biopolymers in the creation of sustainable packaging. Marine algae are also rich in protein and mineral content, they also have anticancer, anti-obesity, and hypolipidemic properties due to the presence of polyunsaturated conjugated fatty acids. The edible films enhance the shelf life of food by controlling moisture without changing the elements of food. The marine algae are collected either in the intertidal or subtidal areas and they will be dried for further process. The edible films are environmentally friendly. The edible film made from marine algae is a mixture of protein, polysaccharides, lipids, and resins. The factors which affect the properties of the edible film are the source of raw material, surface charge, hydrophobicity, polymer chain length, plasticizer type, proportion, and synthesis method. There are numerous research has been conducted to develop edible film using various matrix constituents. This review provides an overview of Marine algae, its process, and edible films, its characteristics, and factors affecting the film
