    The marine sediments of the Vedaranyam coast were examined for their heavy metal contamination largely contributed by natural and anthropogenic activities. Sediment samples were collected and assessed for metals such as chromium (Cr), copper (Cu), manganese (Mn), iron (Fe), Nickel (Ni), zinc (Zn), and cobalt (Co). The individual toxic risk index (TRIi) of metals in this study is significantly variable for Cr (0.88–1.10), Cu (1.78–2.73), Zn (2.33–4.81) and Ni (1.10–4.62). TRIi in the sediments is below 5 for Cr, Cu, Zn, and Ni suggesting the absence of any toxic risk in the aquatic life. To assess the natural and anthropogenic contamination as well as to know the sediment quality, various indices such as the geo-accumulation index, enrichment factor, pollution load index, and contamination factor were computed. The enrichment factor result shows that the heavy metals are primarily from anthropogenic sources. There is a high positive correlation among the heavy metals, indicating a similar origin.

    Rasayan Journal of Chemistry, 2023
    The geochemical characteristics of 33 groundwater samples collected in and around the Kalpakkam area in 2019 were investigated, as well as the effects of seawater intrusion. The dominance of anions and cations is Cl- > HCO3- > NO3- > SO4 and Na+ > Mg >Ca> K. Electrical conductance has exceeded the allowable limit in the northeastern part of the study area, which could be accredited to the proximity of a backwater. The Cl (strong acid) predominates over HCO3 and SO4 (weak acids) in the groundwater of the study region during both seasons of 2019, 90.9 percent and 100%, respectively, based on the hydro-chemical features. The Water Quality Index was determined, and many of the 33 samples fell into the bad category, followed by the nice. The majority of anions and cations show a positive correlation (correlation matrix) with Cl-, especially Na and Mg, suggesting these ions may have been derived from seawater intrusion, secondary salt leaching, and chemical weathering, indicating both natural and anthropogenic origins. The interaction of the ions representing Mg, Ca, Na, and Cl in factors suggests secondary salt leaching or backwater recharge. The study's theme is to examine groundwater's geochemical signatures through geochemical analysis. Using statistical approaches, assess the impact of various pollution sources. The water quality index (WQI) is used to classify the quality of groundwater.
  • Classification of Automatic Detection of Plant Disease in Leaves and Fruits using Image Processing with Convolutional Neural Network

    Proceedings of the 4th International Conference on Smart Electronics and Communication Icosec 2023, 2023
    Detection and identification of disease in plants is the fundamental step to avoid various constraints and to enhance productivity. In agricultural farm, the crops are prone to various bacterial and fungal disease. It is initiated due to the varied ecological conditions and soil categories. The earlier prediction of diseases helps to prevent the complete degradation of crops. The disease is detected through small patches on the leaves of the plant. The evolution of automation and innovations helps in the earlier detection of disease in the leaves and fruits of the crops. It is achieved by artificial intelligence. This is done through the image processing techniques. It uses the comparison of healthy plant leaves to that of the infected leaves and fruits. The classification of disease in the fruits and leaves are done accurately through the convolution neural network. This helps to detect the type and cause of the bacterial and fungal infections. This includes image pre-processing, data acquisition and image classification with feature extraction. Thus the CNN model helps to detect and classify the disease in plant and fruits in agricultural farm.

    Proceedings 6th International Conference on Computing Methodologies and Communication Iccmc 2022, 2022
    In this proposed work, necessary design and optimized parameters are transmitted for the essential information exchange. This research study focuses on integrating WSN architecture. In actuality, many automated systems still require extensive human engagement; for example, a patient may need to visit multiple pharmacies in order to locate a specific sort of drug. A smart inventory system integrating Wireless Sensor Networks (WSN), Quick Response Codes (QR), and cloud services (Web) would solve numerous difficulties while also saving money for both patients and stakeholders. With all these chores, a speedier and more reliable system is required to manage operational and repeatable processes. Recent advancements in the field of portable devices have been substantial, particularly in the area of audio/music information delivery systems such as headphones that link to mobile/portable devices via wired or wireless communication. Usage of headphones connected with mobile devices by all age group people is getting higher practically every day, for doing multiple businesses like navigation, automation, bill payment, contest participation, news and events social media. This paper suggests the usage of four typical home appliances: a fan, a light, a coffee machine, and door alarms, using a single remote. Natural Language processing is used by the mobile device to interpret the user's voice command. To communicate with the Wi-Fi signals provided by these appliances, the project uses a smartphone application. The application gives commands to the Arduino devices and also responds to their responses. While a command is delivered from a remote location. As a result, the integrity and confidentiality of conveyed data, as well as the authentication of the services that provide that data are critical. As a result, security is a vital IoT feature. As a result, it includes a username and password-based authentication mechanism in the mobile application. To assist computers in understanding and responding to commands delivered in natural (human) language. NLP falls under the umbrella of human-computer interaction.

  • Geochemical Characterization and Water Quality Assessment of Groundwater in Arani Taluk of Tamil Nadu, South India

    Geochemistry International, 2020
    The significant geochemical characteristics of the groundwater quality assessment including the impact of monsoon variation of chemical composition of groundwater were determined. 44 groundwater samples were collected in the Arani Taluk of South India and all important physico-chemical parameters including trace metals were determined to characterize and evaluate the hydrogeochemical nature and water quality. In order to evaluate the geochemical characteristics, the order of abundance of the ions in the groundwater is determined for both seasons. In this study, Gibb’s diagram is used to evaluate the mechanism responsible for the change in the chemical composition of groundwater. The unique characteristic of the groundwater has been brought out using the inter-relationship among the principal ions. Utilizing the application of 1 : 1 equiline diagrams, hydrochemical features of the physico-chemical parameters pertaining to the groundwater were evaluated. Reverse ion-exchange study and Chloro-alkaline indices were carried out to evaluate the occurrence of ion-exchange/reverse ion-exchange in the groundwater of the region. The suitability of groundwater to irrigation is studied in detail using various ratios’ including Residual sodium carbonate, SAR and Wilcox and USSL diagrams. The results clearly illustrates that the groundwater of the study area is suitable for irrigation. Water quality studies with respect to trace metals have been carried out and the results show that the water has higher concentration of heavy metals and the results of Heavy metal pollution index also substantiates the fact and many groundwater samples found to show higher values than the allowed limit with respect to heavy metal contamination.
