This document discusses using digital image processing techniques to identify powdery mildew disease in betel vine plants. Digital images of healthy and infected betel vine leaves were collected and converted to grayscale. Histograms were plotted for the grayscale images at different stages of infection and used to create a database. A backpropagation neural network was trained on this data to classify leaves as healthy or infected, and at different stages of infection. The neural network achieved over 99% accuracy in classification, showing this technique can accurately identify powdery mildew disease at early stages.

Plants play an enormous role in human life by providing
them food for living, wood for houses and other resources
to live life.So, human should take care of plants and
agricultural crops. But apart from the human, various
natural factors are there that are responsible for
destroying the growth of plants like unavailability of

Food is one of the basic needs of human being. Population is increasing day by day. So, it has become important to grow sufficient amount of crops to feed such a huge population. Agricultural intervention in the livelihood of rural India is about 58%. But with the time passing by, plants are being affected with many kinds of diseases, which cause great harm to the agricultural plant productions. It is very difficult to monitor the plant diseases. It requires tremendous amount of work, expertise in the plant diseases, and also require the excessive processing speed and time. Hence, image processing is used for the detection of plant diseases by just capturing the images of the leaves and comparing it with the data sets available. Latest and fostering technologies like Image processing is used to rectify such issues very effectively. In this project, four consecutive stages are used to discover the type of disease. The four stages include pre-processing, leaf segmentation, feature extraction and classification. This paper aims to support and help the farmers in an efficient way.

Automated Crop Inspection and Pest Control Using Image ProcessingIJERDJOURNAL
ABSTRACT: Agriculture is the backbone of our country. India is an agricultural country where the most of the population depends on agriculture. Research in agriculture is aimed towards increasing productivity and profit. There are several automated systems available in literature, which are developed for irrigation control and environmental monitoring in the field. However, it is essential to monitor the plant growth stage by stage and take decisions accordingly. In addition to monitoring the environmental parameters such as pH, moisture content and temperature, it is inevitable to identify the onset of plant diseases too. It is the key to prevent the losses in yield and quantity of agricultural product. Plant disease identification by continuous visual monitoring is very difficult task to farmers and at the same time it is less accurate and can be done in limited areas. Hence this projects aims at developing an image processing algorithm to identify the diseases in rice plant. Rice blast disease occurring in rice plant is due to magnaporthe grisea and this disease also occurs in wheat, rye, barley, pearl and millet. Due to rice blast disease, 60 million people are affected in 85 countries worldwide. Image processing technique is adopted as it is more accurate. Early disease detection can increase the crop production by inducing proper pesticide usage.

A Novel Machine Vision System for Identification of Yellow Rust in Wheat PlantsCSCJournals
The crop of wheat is very often infected by a disease that leaves spots of brown, gray or off-white colors on the wheat plants. Scientifically, this disease is known as Yellow Rust. It’s a kind of fungus that often kills young seedlings. The fungus spreads by air. Therefore, it is important to monitor the leaf at regular intervals so as to keep track on quality of growing wheat crop. In the presented paper, a novel machine vision system has been proposed that visual inspects the leaves of the plants and based on spots on leaves, it determines the nature of disease and its depth into the crop. The size of the fungus, color depth and location and locus of the fungus on leaves give an accurate determination of crop quality. In the presented work, the image of the crop leaves are taken by a good quality color camera and processed for getting a gray colored and segmented image depending upon the nature and size of the fungus. A criterion is set for acceptable and rejects crop quality based on the fungus level.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

A Novel Machine Vision System for Identification of Yellow Rust in Wheat PlantsCSCJournals
The crop of wheat is very often infected by a disease that leaves spots of brown, gray or off-white colors on the wheat plants. Scientifically, this disease is known as Yellow Rust. It’s a kind of fungus that often kills young seedlings. The fungus spreads by air. Therefore, it is important to monitor the leaf at regular intervals so as to keep track on quality of growing wheat crop. In the presented paper, a novel machine vision system has been proposed that visual inspects the leaves of the plants and based on spots on leaves, it determines the nature of disease and its depth into the crop. The size of the fungus, color depth and location and locus of the fungus on leaves give an accurate determination of crop quality. In the presented work, the image of the crop leaves are taken by a good quality color camera and processed for getting a gray colored and segmented image depending upon the nature and size of the fungus. A criterion is set for acceptable and rejects crop quality based on the fungus level.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
