Authors: Kakkar Mohit Kumar
Published: June 2024

Over the past few years, there has been increased awareness about the importance of protecting the environment particularly after global warming came up. The approach proposed here in this paper for reducing fuel consumption is the combination of clustering algorithms’ ideas with natural optimization techniques, aimed at efficient route optimization of vehicles. It uses clustering to group customer locations together that in turn allows the development of more efficient routes. The goal of this study is to reduce fuel consumption while optimizing travel plans. This study proposed a nature-inspired algorithm-based model for minimizing fuel consumption in the vehicle routing problem. K-means clustering and the genetic algorithm have been used in this study to find the optimized route with the minimum fuel consumption. It has been observed in this study that routing plans found by the proposed approach consume fewer units of fuel than those generated using optimization techniques which optimize distance covered. This indicates that such an approach could serve as a tool for minimizing fuel consumption in different enterprises.

Authors: Dhiman Poonam
Published: June 2024

Skin malignancies are regarded as the most dangerous disease. Skin cancer has recently received much attention among people worldwide. An earlier diagnosis of skin cancer can lower the mortality rate. Skin cancer can be found and identified via dermoscopy. Automated tools using computer-aided diagnosis models become necessary because visually evaluating dermoscopic images is tedious and time-consuming. The healthcare industry has greatly benefited from recent machine learning advancements like deep learning. Modern technical designs and methodologies make detecting this type of cancer possible; however, automated classification in earlier phases is challenging due to the lack of contrast. As a result, a squeeze net algorithm-based automated computer system is developed for diagnosing skin illnesses. The HAM10000 dataset is gathered for skin lesions. Images of the four skin cancer conditions BCC, DF, MEL, BKL, and NV are included in the dataset. With a 92.25% overall accuracy, 85% precision, 84% recall, and 83% F1 score, the proposed dermonet model did well in classifying skin cancer conditions from the image samples.

Published: June 2024

Mangosteen (Garcinia mangostana L.) generates over 88 billion USD in export revenue to Thailand annually but is restrained due to fruit defects. This study aimed to determine whether smart irrigation with sensors, IoT, and real-time data collection for regulating stable soil water content affects mangosteen fruit quantity and quality. Climate, soil, and mangosteen parameters were compared between irrigated and non-irrigated productions. Flowering and fruit yield data were collected from twenty randomly selected mangosteen trees per irrigation treatment. The results showed that air and soil temperatures were lower, but relative humidity and soil moisture on mangosteen production were greater in irrigated trees than in non-irrigated trees. Irrigated and non-irrigated mangosteen trees showed no significant difference in trunk diameter or crown size. Irrigation boosted mangosteen yields with increased flowers, fruits, and weight but thinner peels, fewer pulp segments, and a higher vulnerability to fruit imperfections. The mean fruit circumference did not differ significantly between non-irrigated and irrigated mangosteen production systems. Mangosteen fruits in irrigated production had fewer fruit defects than those in non-irrigated production. Regulated irrigated mangosteen production with stable soil moisture using soil moisture sensors and IoT produced high-quantity and quality mangosteens with fewer fruit defects. Doi: 10.28991/HEF-2024-05-02-05 Full Text: PDF
