The abstract outlines a research endeavor focused on enhancing Multilevel Inverters (MLIs) for electric vehicles (EVs) and solar photovoltaic (PV) applications. Specifically, it introduces a 53-level MLI design tailored for EVs, leveraging a Switched Capacitor (SC) technique. In this design, the number of SC cells dictates the MLI’s level count, offering simplicity in implementation. With fewer active switches, driving circuits are reduced, leading to cost, size, and device count reductions in the MLI. Additionally, the research incorporates a Maximum Power Point Tracking system based on Artificial Neural Networks (ANN) (MPPT) a Single Input Multiple Output (SIMO) converter and a mechanism. Together, these components increase the DC link voltage with the aid of solar panels, providing a constant DC output voltage and reducing the Total Harmonic Distortion, or THD, in the MLI’s output voltage. The approach of the study entails building a MATLAB simulation model, which is expected to evaluate the performance of the suggested system and confirm that it is effective in accomplishing the stated goals. This research aims to contribute to the advancement of MLI technology for EVs and solar PV systems, emphasizing efficiency, simplicity, and performance optimization.
Air-inflated floats are used for the recovery of the rocket’s spent stage. The floats enable the spent stage to stay afloat in water which is essential for recovery. The stability of the spent stage in ocean conditions with waves is studied as a multiphase CFD analysis solved with the VOF method with a 6 DOF solver and PISO scheme. The ocean conditions vary from calm sea to raging storms and with this wave parameters (wavelength, amplitude, wave velocity) also increase. The study of rocket spent stage retrieval in stagnant water available in the literature was mimicked. The depth of sinking and stress on the spent stage is focused on by studying the angle of inclination, displacement of the rocket stage and the velocity of impact during impact on the ocean surface. With increasing wave characteristics, the rocket stage becomes more unstable experiences more stress, and topples quickly.
The need for responsive and transparent services is growing for governments in the quickly changing world of today. This study investigates how machine learning can improve public governance by improving the intelligence and empathy of resource management and grievance redress [7]. We create systems that use natural language processing to comprehend the complex feelings that underlie citizen complaints, automatically classifying and ranking them to guarantee that pressing problems are addressed in a timely manner [1, 6].The system forecasts community needs and optimizes resource deployment before issues worsen by combining predictive analytics with geographic data. The fundamental innovation is the transition of government from reactive bureaucracy to proactive, human-centered service, which allows officials to more effectively and empathetically serve their communities [3]. Our method incorporates human values into AI design, understanding that technology should enhance public servants’ compassion rather than replace it. A future where people feel heard, resources are distributed equitably, and governance is both wise and compassionate is promised by this blend of data-driven insight and human-centered design.
Water is a vital component of the planet that is required for life to exist. Water quality steadily declines due to unplanned urbanization, fast industrialization, and uncontrollable human meddling. Humans are impacted by this in addition to marine animals. In this experiment, regular testing of the quality is necessary. Water quality should be monitored by assessing parameters related to its quality. Measurements taken at the site are frequently used to evaluate water quality. While these assessments are precise, they are expensive and don't show changes in water quality over time or in specific locations. To overcome this limitation, the Artificial Intelligence-based framework is proposed to monitor and check water quality using a Recurrent Neural Network algorithm. The suggested algorithm is well-trained to find the water quality with the help of a dataset. This paper's primary goal is to evaluate the methods used to build the dataset for water quality prediction and the Frameworks such as Internet of Things (IoT) and Artificial Intelligence (AI) available to monitor water quality. Moreover, a comparison of the various neural network approach performances is available for Water Condition Assessment.
Leishmania braziliensis cutaneous leishmaniasis (CL) remains a major public health challenge due to the toxicity, variable efficacy, and emerging resistance associated with systemic therapies. However, few topical candidates have been successfully developed despite growing guideline support for local treatment in many patients. This study evaluated the antileishmanial, immunomodulatory, and proregenerative effects of a topical formulation combining triterpene saponins from Sapindus saponaria (SS) and a synthetic chroman hydrazone (TC2) using a standardized hamster model of L. braziliensis CL. The antiparasitic and immunomodulatory effects of TC2-SS were examined in human monocytederived macrophages infected with L. braziliensis, assessing intracellular parasite burden, macrophage morphology, nitric oxide (NO) and reactive oxygen species (ROS) production, and cytokine expression by ELISA and RT-qPCR. In vivo efficacy and early wound-healing responses were evaluated in a dorsalskin hamster model treated topically with 4% TC2SS and compared with intralesional meglumine antimoniate, including epidermal growth factor (EGF) and transforming growth factor β1 (TGFβ1) expression. TC2-SS reduced intracellular infection (EC₅₀ 12.83 ± 0.97 µg/mL), decreased parasite burden, and induced macrophage activation-like morphological changes. The formulation preserved infectiondriven NO and ROS and selectively enhanced late NO in infected cells. Cytokine analyses revealed coordinated suppression of IL-1β, TNF-α, IL-4, IL-10, and TGF-β1, preserving MIP-1α. In vivo, TC2-SS achieved cure rates comparable to those of antimonials, with uniform lesion regression, no treatment failures, no systemic toxicity, and an increased ratio of EGF/TGF-β1. Thus, TC2-SS provided dual antileishmanial and host-directed benefits, supporting its advancement as a topical therapeutic candidate for L. braziliensis CL.
