Water is one of the basic needs for all living and nonliving things. It is important to sustain the available water resources effectively for future generations. A lot of studies are employed already to improve the performance of solar desalination systems rather than conventional methods. Subsequently, an experimental approach is proposed with energy, exergy, economic, environmental, exergoenvironmental, exergoeconomic, and enviroeconomic performance of photovoltaic/Thermal (PV/T) solar distillation system using two methods to enhance the fresh water yield production at feasible cost. First is the conventional solar still (CSS) with PV and second is PV with double fan solar still (DFSS) with optimized running time of the double fan, which increases the productivity of the solar distillation system. The results show that average daily energy and exergy efficiency of the system improve with DFSS (19.98%, 1.36%) than CSS (11.74%, 0.36%). The daily yield productivity of CSS is 1.618 L m−2 and is increased as 2.482 L m−2 with DFSS. Average cost of water yield production is also reduced with DFSS and estimated as 0.018$, 0.016$, and 0.015$ for the lifetime of 15, 20, and 30 years for CSS and 0.014, 0.013, and 0.012$ for DFSS. Overall, the proposed methodology shows promising results than the conventional approach.

This manuscript proposes a hybrid technique for the optimum location of micro‐phasor measurement units (μ‐PMUs) in the distribution system (DS).The proposed hybrid approach is the wrapper of dwarf mongoose optimizer (DMO) and pelican optimization algorithm (POA). The updating behavior of DMO is improved by the POA; therefore, it is called DMO‐POA approach. The main aim of the proposed approach is to avoid discontinuity of supply and minimizes the count of PMDs to reduce cost and attain the maximal count of measurement‐redundancy that is limited to full‐system observability for IEEE bus‐system in zero injection nodes (ZINs) and tie‐switches. The proposed approach considered the optimum count of μ‐PMUs is needed for the thorough distribution system economy, observability, and the reliability measure. The proposed approach considers the distribution of PMUs in the reconfiguration of smart‐distribution‐grids, ZINs and communication system requirements. Here, the objective‐function is aiming at minimizing the costs of reliability and capital. The proposed method uses the infrastructure of communication cost to simultaneously co‐optimize the system switching strategy and find the optimal sites for PMUs. The performance of the proposed technique is tested in different test‐systems, like IEEE‐14 bus, 13, 34, 37, and 123 buses and the performance is executed by comparing it with the existing approaches. Furthermore, the proposed system is effectual to find an optimal solution with less computation and decreases the complexity of the algorithm.

SummaryIn this article, an advanced reversible stenographic method is proposed for image and video frames by adapting dual tree complex wavelet transform and chaotic whale optimization algorithm. Here, the cover image and secret message are taken as input. In this image, the edges are identified by Canny edge detection system and embedded by the process of dual‐tree complex wave transformation method (DT‐CWT‐CWOA‐SDH) and pixel edges are optimized using the chaos whale optimization algorithm (CWOA), it optimizes the edge pixel variations and maximizes the robustness of the image and visual quality of stego image. The objective of this process is to increase the security of secret data hiding the secret message on cover image and forming the stego image by the embedding procedure and to maximize the peak signal‐to‐noise ratio (PSNR) and reduce the execution time. The proposed method runs on the MATLAB work site and the performance of proposed method is evaluated using different existing methods. The simulation outcomes illustrate that the proposed DT‐CWT‐CWOA‐SDH shows higher PSNR of 32.01%, 24.79%; lower mean square error (MSE) of 21.13%, 45.185%, normalized correlation (NC) of 11.24%, 19.04% compared with existing method.
