    Intelligent farming technology helps farmers overcome tough obstacles in the farming process, such as increased sup-plier costs, a lack of labour, customer satisfaction, and more. Artificial Intelligence (AI) is a remarkable technology in smart farming because it deeply understands the issue and can help farmers make decisions. This article's main objective is to identify and examine the concepts and techniques of Convolutional Neural Networks (CNN) technology that could aid in classifying the ripeness stages of fruit in intelligent farming. This paper systematically reviews 18 previous works for classifying the ripeness stages of fruit. This review outlines the most commonly used algorithms, activation functions, optimisation functions, and platforms for algorithm implementation. In addition, found that not all algorithms are suitable for even near-equivalent processes. Therefore, this study suggests the intensity of the CNN algorithms concerning various metrics to find the suitability for the operations/applications. Finally, this paper offers some future research directions in the ripeness classification of fruits

    Euphorbia hirta L. (Family: Euphorbiaceae) is a versatile medicinal plant and enriched with novel bioactive molecules and possess broad-spectrum pharmacological actions. Present work is aiming to synthesis and characterize of silver nanoparticles (AgNPs) by bioreduction method an using ethanolic extract of aerial parts of Euphorbia hirta L. (EH-ET). The synthesized AgNPs observed by a color change of source solution (as AgNPs) and further confirmed by the UV-Visible spectroscopic technique. The AgNPs synthesized were characterized by Scanning Electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and Zeta potential analysis. The synthesized AgNPs are polydispersed and some places it’s agglomerated. The particle size EH-ET silver nanoparticles were analyzed using Beckman coulter particle size analyzer (DelsaTM Nano common). The average size of the particles size noted in 2.9-206.3 nm. Anticancer activity of EH-ET Silver nanoparticles was tested against neuroblastoma cells (SH-SY5Y) and breast cancer cells (SH-SY5Y) and cytotoxicity were tested in vero cells by MTT assay. The preliminary confirmation of the synthesized AgNPs by the present method was made by the appearance of reddish brown color and the visible absorption peak at 429.5 nm. SEM image revealed that AgNPs synthesized were spherical in shape and silver nanoparticles were in the size range of 2.9 to 206.3 nm. FT-IR spectra showed the peaks corresponding to functional groups C=O, -C=C and -OH, which actively participated in bio-reduction and subsequent stabilization reactions in the synthesis of AgNPs. The obtained nanoparticles showed promising anticancer activity against neuroblastoma cells (SH-SY5Yc) and breast cancer cells (MCF-7) with IC50 values of 29.85 and 335 µg/mL, respectively. Whereas, the nanoparticles did not show any activity against vero cell lines. The synthesized silver nanoparticles using an ethanolic extract of Euphorbia hirta L. would be helpful for the preparation of potent cytotoxicity agents to destroy cancer cells

    A replicated field trial on biocontrol of coriander wilt caused by Fusarium oxysporum f., sp. coriander; was conducted in kharif season during 1995-96, 1996-97 and 1997-98 in the Department of Spices and Plantation Crops, Horticultural College and Research Institute, TNAU, Coimbatore. Seed treatment with Trichoderma viride at 4 g kg-1 of seed was found to be more effective in reducing the wilt incidence to 5.3 per cent as against 28.3 per cent recorded in untreated, control plots in all the three years. The mean yield (387.5 kg ha-1) for all the three years was also significantly higher in seed treatment with T. viride as against very low yield (162 kg ha-1) obtained in untreated plots. The cost benefit ratio was also enhanced with the same treatment. &nbsp

    Polypyrrole films were deposited by anodic electropolymerization on stainless steel substrates from aqueous pyrrole solutions containing sodium salicylate and tiron additives. The deposition yield was studied under galvanostatic conditions. The amount of the deposited material was varied by the variation of deposition time at a constant current density. SEM studies showed the formation of porous films with thicknesses in the range of 0–3 μm. Cyclic voltammetry data for the films tested in 0.5 M Na2SO4 solutions showed capacitive behavior and high specific capacitance (SC) in a voltage window of 0.9 V. The films prepared from pyrrole solutions containing tiron showed better capacitive behavior compared to the films prepared from the solutions containing sodium salicylate. A highest SC of 254 F g−1 was observed for the sample with a specific mass of 89 μg cm−2 at a scan rate of 2 mV s−1. The SC decreased with an increasing film thickness and scan rate. The results indicated that the polypyrrole films deposited on the stainless steel substrates by anodic electropolymerization can be used as electrodes for electrochemical supercapacitors (ES)

    Analytical framework for Adaptive Compressive Sensing for Target Detection within Wireless Visual Sensor Networks

    Wireless visual sensor networks (WVSNs) are composed of a large number of visual sensor nodes covering a specifc geographical region. This paper addresses the target detection problem within WVSNs where visual sensor nodes are left unattended for long-term deployment. As battery energy is a critical issue it is always challenging to maximize the network's lifetime. In order to reduce energy consumption, nodes undergo cycles of active-sleep periods that save their battery energy by switching sensor nodes ON and OFF, according to predefined duty cycles. Moreover, adaptive compressive sensing is expected to dynamically reduce the size of transmitted data through the wireless channel, saving communication bandwidth and consequently saving energy. This paper derives for the first time an analytical framework for selecting node's duty cycles and dynamically choosing the appropriate compression rates for the captured images and videos based on their sparsity nature. This reduces energy waste by reaching the maximum compression rate for each dataset without compromising the probability of detection. Experiments were conducted on different standard datasets resembling different scenes; indoor and outdoor, for single and multiple targets detection. Moreover, datasets were chosen with different sparsity levels to investigate the effect of sparsity on the compression rates. Results showed that by selecting duty cycles and dynamically choosing the appropriate compression rates, the desired performanc
