The Suppression of Thrust Ripple and Electromagnetic Vibration in A Double-sided Flux Switching Permanent Magnet Linear Motor by Optimizing the Stator Structure
type: item
description: The Double-Sided Flux Switching Permanent Magnet Linear Motor (DLFSPM) is being increasingly and extensively employed in various fields due to its merits of high efficiency and high power density. Nevertheless, the DLFSPM suffer from significant thrust ripple, which exacerbates electromagnetic vibration. To effectively reduce thrust ripple and electromagnetic vibration, this paper aims to significantly enhance its performance by optimizing the stator structure. Firstly, establish the finite element analysis model of the DLFSPM, and based on theoretical methods, derive the electromagnetic thrust equation and the equation of electromagnetic vibration, clarifying the key indicators. Secondly, effective suppression of thrust ripple is achieved by optimizing the radius of the arc fillet in the stator slot. Subsequently, auxiliary slots are introduced on the stator tooth surface, and their optimal dimensions are determined using the finite element model and response surface methodology, with the objective functions of enhancing electromagnetic thrust and reducing thrust ripple. Finally, a comparative analysis is conducted between the comprehensively optimized DLFSPM and the initial structure motor regarding electromagnetic thrust, thrust ripple, and electromagnetic vibration. The simulation results demonstrate that the optimized DLFSPM not only significantly improves electromagnetic thrust but also effectively suppresses thrust ripple and electromagnetic vibration, thereby validating the effectiveness of the optimization method.

Nighttime Light Data and Spatial Modeling for Land-Use Carbon Emissions: Insights from Northeast China
type: item
description: Carbon emissions are a critical global issue requiring detailed spatial analyses to support regional carbon peak and neutrality strategies. This study investigates the spatiotemporal evolution and spatial differentiation of county-level land-use carbon emissions (CELU) in the Changchun-Jilin-Tumen (CJT) region from 2012 to 2021 by integrating land use data, nighttime light imagery, and socio-economic statistics with the Optimal Parameter Geodetector (OPGD) model. The analysis identifies key drivers of spatial emission variability, including construction land proportion (q-value: 0.8882), land area per capita (q-value: 0.7609), and urbanization rate (q-value: 0.5875), underscoring the significant role of land-use patterns and urbanization. Results show a 21.2% increase in CELU, from 67,594.46×104 t in 2012 to 81,942.35×104 t in 2021, with emissions concentrated in industrially active and urbanized western and southern counties, while forest-rich central and eastern counties exhibit lower emissions. Using the Grey Model (GM (1,1)), the study forecasts that CELU will rise from 78,484.364×104 t in 2022 to 88,985.198×104 t by 2030, reflecting a 14% increase over the forecast period. This trajectory highlights the misalignment between current trends and the region's goals of creating a "low-carbon industrial zone" and "livable cities," emphasizing the need for transitioning to renewable energy, optimizing industrial structures, and implementing sustainable land-use practices such as brownfield redevelopment and ecological land protection. By combining advanced remote sensing with nonlinear spatial analysis, this study offers a replicable high-resolution framework for understanding carbon emission drivers and spatial patterns, providing actionable insights for refining carbon reduction strategies and achieving sustainable development goals at both national and global scales.

Intrinsically High Refractive Index Silicone Polymers Containing S and P Heteroatoms
type: item
description: There is growing interested in high refractive index polymers due to their numerous applications in optical materials. In current work, we reported a facile strategy to improve the refractive index of the optical materials. The new asymmetric binary thiol dopants containing high molar refractive index heteroatoms (S and P) and large conjugated groups were successfully designed and synthesized. Using these additives, the high refractive index silicone polymers were developed from these dopants and vinyl silicones simply via the light-cured reaction. The effects of dopants’ structure and content on the thermal and optical properties of cured silicone polymers were systematically investigated. The results show that the asymmetry structure of the dopants can not only effectively offset the accumulated trend of the large conjugated groups but also improve the refractive index of cured silicone polymers. Even with 5% dopant’s loading, the refractive index of the SOV-5 increased from 1.5773 to 1.5803 without notably sacrificing its the light transmittance. The glass transition temperature of the cured silicone polymers decreases, even though their crosslink density increase with the growing of the dopants’ loading.

Exploration on the Role, Function and Cultural Mission of Art Think Tanks in the "Digital Communication of Intangible Cultural Heritage"
type: item
description: As an important part of the new type of think tank with Chinese characteristics, art think tanks play an important role in enhancing the accuracy of the inheritance of intangible cultural heritage and art, and improving the foresight of the development of intangible cultural heritage and art. As one of the main dissemination paths of intangible cultural heritage today, the accuracy and efficiency of "digital communication" cannot be separated from the active participation of art think tanks. [Method/Process] Starting from the positive role of art think tanks in "digital communication of intangible cultural heritage", this paper explores the necessity of art think tanks participating in the new type of intangible cultural heritage dissemination path through literature research, comparative analysis, induction and summary, as well as the positioning, function and cultural mission of art think tanks in it. [Result/ Conclusion] The positive impact of art think tanks on the dissemination of intangible cultural heritage and other important cultural dissemination in China is mostly in macro-guidance, and they rarely play an important role in the "new dissemination method" of a certain culture. "Digital dissemination" has gradually become the mainstream method of cultural and artistic dissemination with its advantages of "fast speed", "wide range", "large content" and "high public participation". The study believes that exploring the role of art think tanks in the process of "digital dissemination of intangible cultural heritage" will help solve the problems of "uneven quality of dissemination content" and "low participation intention of young groups", and thus disseminate intangible cultural heritage and enhance China's cultural soft power in a more accurate and efficient way.

An Aeromagnetic Compensation Algorithm based on Complete Ensemble Empirical Mode Decomposition with Adaptive Noise and a Physics-Guided Neural Network
type: item
description: Aeromagnetic exploration is a magnetic field exploration method that detects changes in the spatial magnetic field by carrying a magnetometer on an aircraft. However, during the measurement process, the magnetic field data is often interfered by the aircraft’s own ferromagnetic materials and maneuvers. The role of aeromagnetic compensation is to eliminate this part of the interference, which is crucial to improving the quality of aeromagnetic exploration data. In this study, we introduce a novel method for aeromagnetic compensation, which is employed to eliminate the interference from aircraft platforms. The proposed method utilizes complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) to decompose the magnetic field data into multiple feature components. These decomposed features are subsequently input into a physics- guided neural network (PGNN), which was designed to remove magnetic interference from the data. The core idea behind this method is that CEEMDAN effectively decomposes magnetic field data into features that are more easily learned by the neural network. The method leverages both data-driven and model-driven advantages by embedding the Tolles–Lawson (T-L) model into the neural network, thereby compensating for both linear and nonlinear interference. The results of simulation and real experiments show that the proposed method outperforms traditional model-driven and data-driven techniques, especially when the quantity and quality of data are limited.

Optimization of Induction Electricity in Buildings by Ultra High Voltage Transmission Lines
type: item
description: With the rapid development of China's economy, the demand for electricity, as the lifeline of the economy, is naturally increasing year by year. At the same time, China's market-oriented reform of electricity has shown initial results, a diversified competitive pattern is forming, and the commodity attributes of electricity have been further improved. The role of allocating electricity resources is also gradually strengthening, and there is a clear growth trend in market-oriented trading of electricity. There is an imbalance in the distribution and load centers of energy in China, and the corresponding resource points and load centers are also relatively far away. Due to the shortage of transmission corridors in China, a considerable portion of ultra-high voltage lines are distributed in residential areas. At this time, the impact of buildings close to residential areas on high-voltage transmission lines, as well as more in-depth guidance for transmission line installation and distribution in residential areas, will play a certain guiding role. Therefore, it is particularly important to study the influence of electric field distribution under different conditions on transmission lines. This article reasonably simplifies the three-dimensional model of transmission lines and introduces a line charge unit model to simulate the three-dimensional electric field near ultra-high voltage transmission lines. At the same time, simulation research is conducted on the three-dimensional electric field in different situations, namely in buildings of different materials.

Leveraging Machine Learning to Analyze and Predict Cultural Trends in Global Tourism
type: item
description: Cultural trends, economic factors, and digital transformations shape fast-evolving global tourism. Machine learning is used in this study to analyze and predict cultural shifts in tourism on the basis of the fusion model by combining the architectures of EfficientNet and DiCENet. The model also integrates diverse data sources, which include online travel reviews, social media content, and macroeconomic indicators, to create a detailed framework to explain new travel behavior. The results indicate a strong recovery in positive traveler sentiment post-pandemic, alongside significant growth in sustainable travel, digital nomadism, and wellness tourism. The major influence on tourism demand was the level of economic stability, specifically GDP per capita and unemployment rates. In comparison, machine learning baseline models showed an accuracy rate of 92.5% in detecting and predicting trends under the EfficientNet-DiCENet fusion model. These results provide a basis for stakeholders in the industry, including policymakers and businesses, to make decisions that take advantage of evolving passenger air travel preferences in order to align the strategies. Even though the study showcases the impact of machine learning in tourism analytics, a number of shortcomings, such as data bias and the unpredictability of external disturbances, have been identified as research areas for the future. In general, this work contributes to the use of AI-driven models for data-driven tourism forecasting and cultural trend analysis.

Molecular Pathways of Glaucoma Progression: Current Perspectives
type: item
description: Glaucoma is a progressive optic neuropathy characterized by retinal ganglion cell (RGC) degeneration and irreversible vision loss. Despite extensive research, the molecular mechanisms underlying glaucoma pathogenesis remain incompletely understood. Recent studies highlight the crucial role of non-coding RNAs (ncRNAs) in modulating key pathways associated with trabecular meshwork (TM) dysfunction, retinal neurodegeneration, and fibrotic remodeling. This review provides a comprehensive analysis of the involvement of microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs) in glaucoma progression. We discuss their regulatory influence on pathways such as the TGF-β, PI3K/AKT, MAPK, and Wnt/β-catenin signaling cascades, which are implicated in oxidative stress, extracellular matrix (ECM) remodeling, apoptosis, and fibrosis. Notably, ncRNAs such as miR-29b, miR-200a, and MALAT1 exhibit differential expression patterns in glaucomatous tissues and modulate critical cellular processes that impact intraocular pressure (IOP) regulation and RGC survival. Furthermore, we explore the potential of ncRNAs as diagnostic biomarkers and therapeutic targets for glaucoma. While ncRNA-based therapies hold promise, challenges such as delivery efficiency, immune responses, and target specificity must be addressed before clinical translation. Future research should focus on elucidating the precise molecular interactions of ncRNAs, optimizing drug delivery systems, and conducting large-scale clinical studies to validate their therapeutic potential. Understanding the intricate network of ncRNA-mediated regulation in glaucoma could pave the way for novel, targeted treatment strategies, ultimately improving patient outcomes and preserving vision.

Impact of Promoting Fuel Cell Vehicles on Urban Air Quality and Health Benefits
type: item
description: Fuel cell vehicles (FCVs) are considered a promising clean energy transportation option with significant potential to alleviate urban air pollution. However, their environmental benefits are not fixed but are influenced by various factors, including vehicle usage patterns and road conditions, which in turn affect air quality and public health. This study takes Xi’an as a case study and employs the COPERT model to develop a 2020 emission inventory for FCVs. Future vehicle ownership in 2035 is projected under low, medium, and high electrification scenarios using multiple models. The WRF-SMOKE-CMAQ modeling system is utilized to simulate air quality changes, while the BenMap-CE model is applied to assess health benefits. The results indicate that under the high electrification scenario, pollutant emissions are reduced by 64.59%–88.86% compared to 2020 levels, with pollutant concentrations exhibiting a gradient distribution along the road network. In winter, CO, NO₂, and PM₂.₅ concentrations are significantly higher than in summer. Improved air quality leads to substantial health benefits related to PM₂.₅, with the high electrification scenario preventing an estimated 770 premature deaths and generating up to 400 million CNY in economic benefits. These findings demonstrate that the widespread adoption of FCVs can effectively reduce urban traffic-related pollution burdens and yield significant environmental and health co-benefits, providing a scientific basis for clean transportation policymaking.

By downloading Global30 land use data for 2000, 2010, and 2020, we utilized ArcGIS for mask extraction, raster reclassification, and data integration to standardize land categories and facilitate comparative analysis. Subsequently, we systematically analyzed the area, change magnitude, and dynamic degree of land use on both sides of the Tumen River Basin over the past two decades. Through spatial operations such as overlay analysis in ArcGIS, we further employed land use transfer matrices and transition probability matrices to examine the characteristics of land use type conversions. Key findings include: 1.Forest reduction: Forest areas on both sides of the basin decreased, primarily due to insufficient environmental awareness and overexploitation of resources in the early 2000s. 2.Water body expansion: China’s water conservancy projects increased total water area by approximately 66.39 km², while North Korea’s water bodies remained stable. 3.Policy-driven shifts: Land use changes were closely linked to national policies and human activities, with recent improvements attributed to sustainable development initiatives

Electric Field Optimization Analysis for Live Opera-Tion of UHV Transmission Line
type: item
description: At present, China's economy is in a period of rapid development, and the pace of urbanization construction is constantly accelerating, followed by the soaring demand for electricity. Especially in densely populated areas where construction land is scarce, it is difficult to balance transmission capacity with the increasing demand for electricity. The problem of insufficient conveying capacity is solved well by the double-return conveying scheme of the same tower and frame. In the process of transmission line operation, it needs to be repaired and maintained, and a considerable part of the work needs to be live. Therefore, this paper studies the surface electric field changes of UHV live line workers, in order to reduce the operating risk of operators, and then make theoretical and practical contributions to ensure the safe and effective implementation of live line work and improve the operation quality and standardization degree. In this paper, SolidWorks modeling software is used to model a 500KV transmission line, and a human body model is placed in the model. The finite element simulation software COMSOL is used to calculate the surface electric field when the personnel are located at the typical position of the line, and its influencing factors are analyzed.

Effects of Land Use Change on Habitat Quality in the Tumen River Basin
type: item
description: Habitat quality is one of the important factors to measure ecosystem services, and its quality is directly related to regional ecosystem service capacity. The Tumen River Basin is located in the border area of China, Korea and Russia. The temporal and spatial evolution of habitat quality in Tumen River Basin is of great significance to the ecological security and sustainable development of Northeast Asia. Based on InVEST model and spatial autocorrelation, this study analyzed the temporal and spatial changes of habitat quality and the interaction of elevation in Tumen River Basin (Chinese side). The results showed that: 1) Land transfer mainly occurred from cultivated land to construction land and grassland, and from forest land to cultivated land from 2000 to 2018. 2) In the past 20 years, habitat quality in the study area fluctuated, showing an upward trend and then a downward trend, but the overall fluctuation was not significant, with an average value of 0.87. 3) The elevation effect of habitat quality and degradation degree was obvious on elevation. The distribution of low-grade habitat quality was consistent with that of cultivated land and construction land, while that of high-grade habitat quality was consistent with that of forest land. Overall, the habitat quality index increased with elevation. The results can provide some reference for biodiversity conservation and ecological sustainable development in Northeast Asia.

Analysis, Assessment, and Remediation of Highway Rockfall
type: item
description: Preventing geological disasters such as highway rock collapses is crucial for ensuring traffic safety and social stability. Traditional research often relies on on-site investigations to identify collapses, which can delay the remediation process. In this study, we focused on a highway rock collapse case in Shuangfeng Town, Longchang City. Using a combination of remote sensing imagery analysis, on-site verification, and surveying, we comprehensively obtained the geological characteristics and surrounding environmental information of the dangerous rock mass. Through detailed analysis of the lithology, structure, weathering degree, and other features of the dangerous rock mass, and considering geological structures, climatic conditions, human activities, and other internal and external factors, we explored the formation mechanism of the rock collapse in depth. Subsequently, we assessed the potential threat level of the dangerous rock mass to provide a scientific basis for the design of the remediation plan. The results indicate that the dangerous rock mass in this area is primarily composed of gray thick-bedded to blocky fine-grained sandstone from the Middle Jurassic Shaximiao Formation, with two sets of steeply dipping "X" joints. Stability analysis reveals that under natural conditions, the dangerous rock mass is relatively stable, but its stability significantly decreases under heavy rainfall conditions, becoming unstable. Based on these findings, we proposed a "manual rock clearance" plan. Testing confirmed that this plan.achieved the intended goals and ensured the safety of the area.

A Fast Numerical Method for Magnetic Field Analysis of Coaxial Magnetic Gears with Bridge-Connected Modulators Considering Magnetic Saturation
type: item
description: This paper presents a novel approach for calculating the magnetic field distribution of magnetic gears(CMGs) with bridge connection in modulator. The modulator and bridge connection regions were divided into several unit modules to derive a convolution matrix of permeability. The magnetic field distribution was then calculated using spatial harmonic modeling method(SHMM). To accurately account for the influence of nonlinear permeability and saturation on the magnetic field distribution, the permeability curve of the material was incorporated, and the permeability distribution function was modified using an iterative method. To verify the method, the magnetic field distribution of two sets of magnetic gears with different bridge parameters was calculated. The proposed method for accurately calculating the magnetic field distribution of CMGs with bridge connections is validated by comparing it with the results obtained from finite element analysis(FEA).

Firm Entry and the Growth of The Science Parks based on Energy Innovation: Evidence from Beijing Zhongguancun Science Park in China
type: item
description: Understanding the micro-level dynamic mechanism of economic growth of the science park is of great significance to the theory of regional economics and the policies to promote innovation. Based on the novel firm-level data from 2005 to 2015 on Beijing Zhongguancun Science Park (Z Park for short) in China, this paper investigates the dynamic impacts of firm entry on Z Park’s growth, measured by productivity and size, respectively, and an extended analysis is conducted from the perspective of energy utilization and innovation. By employing the DOP and EEKT decomposition methods, we first find that new entrants have a lower TFP and output than incumbent firms. However, in the following years, the relative growth rates of them are faster and gradually converge to or even exceed the latter in both the TFP and output level. Second, the new enterprises do not significantly promote the annual TFP growth of Z Park in the year of entry but finally enhance the TFP growth on average during these ten years. Third, different from the impact on the growth of TFP in Z Park, new entrants contribute substantially to the annual output growth of Z Park in the year of entry, and this effect has further increased on average. The analysis combined with energy utilization shows that with the entry and growth of new enterprises, they are gradually showing potential in improving energy efficiency and innovating energy technology. These findings provide valuable insights into the dynamics of economic growth in science parks and suggest potential strategies for promoting innovation for policymakers.

The Application of Energy Consumption Prediction Model for Fresh Air System based on PSO-BP and BO-BP
type: item
description: With the fast progress of deep learning and neural network technology, neural networks are now being used in lots of different subjects. They have been especially popular in predicting energy use in fresh air systems, because of their ability to fit nonlinear data. However, the performance of neural networks largely depends on the selection of their hyperparameters, and how to effectively optimize these hyperparameters has become a key issue to improve the prediction accuracy of the model. This paper discusses the methods of optimizing the hyperparameters of neural networks and compares several optimization methods, and finally finds that the Bayesian optimization algorithm performs optimally in neural network optimization. In the experiment, firstly, the relevant data of the new wind system were collected and data preprocessing was carried out, including missing value interpolation and outlier detection. The key factors affecting the energy consumption of the fresh air system were then used to train a prediction model. Then, PSO and BO were used to improve the neural network's hyperparameters. A Monte Carlo simulation showed the Bayesian algorithm identifies the global optimum more quickly, improving prediction accuracy. Experimental findings show that factors like indoor-outdoor temperature, humidity and air quality influence the energy consumption of fresh air systems.The BP neural network model, optimised by the Bayesian optimisation algorithm, performs better when predicting energy consumption. Research results offer an effective energy consumption prediction method for fresh air systems and important experimental support for related energy prediction tasks.

Design and Manufacturing of Ultra-Thin Square Power Battery Aluminum Shell Forming Die
type: item
description: Increased demands on lightweight and high-performance battery casings of electric vehicles (EVs) and energy storage systems require cutting-edge forming technology to overcome challenges of conventional deep drawing and stamping, where usually thickness inhomogeneity, residual stress, and defects would be caused. The research deals with the designing and optimization of an ultra-thin square aluminum shell power battery forming die utilizing roll forming technology for improving size accuracy and mechanical reliability. A finite element model for simulation to optimize roll forming parameters, such as rolling force and pass geometry, was established and verified experimentally for thickness distribution assessment, defect minimization, and spring back minimization. The comparative study against deep drawing and stamping techniques reveals that roll forming results in 50% thickness variation reduction, 63% dimensional accuracy improvement, and 75% defect rate minimization. Furthermore, spring back effects were decreased by 42–60%, and shape retention and structural stability were improved. The results confirm that roll forming enhances production accuracy, reduces human errors, and improves overall efficiency, making it a good candidate for scalable next-generation production of batteries. From the data, it can be deduced that roll forming is a better alternative when compared to traditional forming as it helps in achieving better sustainability, less material waste, and increased reliability for future energy storage technologies.

Genetic Algorithm-based Model Predictive Control for Partial Shading Mitigation on PV Array
type: item
description: Photovoltaic (PV) energy harvesting systems experience performance deterioration and efficiency drops mostly due to mismatching and partial shading conditions (PSCs). Although different algorithms have been established to mitigate the negative impact due to PSCs, there are still some challenges concerning the algorithms’ robustness, accuracy, and reliability. To alleviate the effects of partial shading and enhance output power, PV array reconfiguration techniques emerged as solutions to this challenge. The purpose of this paper is to introduce the genetic algorithm (GA) based model predictive control (MPC) in order to mitigate the impact of PSCs on the PV array. This algorithm is considered due to its capability of taking multiple inputs and generating multiple output predictive signals. The proposed algorithm is implemented and simulated on MATLAB/Simulink for PV array performance optimization under PSCs. The results show that the GA-based MPC does not only mitigate the effects of PSCs but optimizes the PV array’s performance as well. From the simulation results, the GA-based MPC significantly increased the overall power output from 562.0 W (under PSCs) to 852.6 W which is almost the maximum power (under normal conditions), making an improvement of 290.6 W which is technically 51.17 % of the overall power generated by the system.

title: The Impact of Implementing the International Financial Reporting Standard for Insurance Contracts (IFRS 17) On the Financial Performance of Insurance Companies Listed on the Amman Stock Exchange (Jordan)
description: This study aimed to identify the impact of implementing the International Financial Reporting Standard for Insurance Contracts (IFRS 17) on the financial performance of insurance companies listed on the Amman Stock Exchange (Jordan).** To achieve this objective, the study adopted a descriptive-analytical approach, which aligned with the nature of the research. Financial statement data from insurance companies was analyzed both before and after the implementation of IFRS 17, with a comparative analysis conducted between the two periods. The researchers utilized appropriate statistical methods through STATA software. The results demonstrated that the independent variable—the implementation of IFRS 17—had a positive impact on the financial performance of insurance companies listed on the Amman Stock Exchange. The study concluded that IFRS 17 represents one of the most significant developments in Jordan's insurance sector. To ensure its continued successful implementation, greater preparation, planning, and execution of the standard are required. Jordanian insurance companies must monitor the effects of this new standard on their financial data, related systems, controls, processes, and outputs. Necessary improvements should be made to enhance the quality of these companies' financial performance and the reliability of their financial reports and statements. This, in turn, will positively impact users of financial statements in particular and investment activities in general.

Investigation on the Structure and Optical Properties of Fe2+:ZnSe Quantum Dots Synthesized by Microemulsion Method
type: item
description: ZnSe quantum dots (QDs) have intensively studied because of their unique optical properties and enormous applications. By doping transition metal ions in ZnSe QDs, their properties can be further optimized and new functions can be given. In this work, Fe2+ doped ZnSe QDs were successfully prepared using inverse microemulsion-assisted hydrothermal method, and advanced characterization methods were used to systematically study their structure and optical properties. The research results showed that Fe2+ was successfully doped into the ZnSe lattice, and with the increase of Fe2+ doping concentration, the particle size of QDs gradually decreased. The actual doping ratio of Fe2+ was about 41% of the initial concentration. Optical properties studies showed that Fe2+ doping reduced the band gap width of ZnSe QDs from 2.43 eV to 1.96 eV. The synthesis of Fe2+ doped ZnSe QDs provides new possibilities for its application in optoelectronic devices and photocatalysis.

Performance Analysis of Solar Still for Potable Water Under Different Pressure Conditions
type: item
description: The present work is an outlook to enhance the productivity of a basin type double slope Solar Still with variant pressure. In India three fourth of its rural population is not having access to piped and clean drinking water and the scenario is not much different even in metropolitan cities. Only in Hyderabad, government spent 1450 crores as drinking water project and also provided 20 kiloliter per month to its consumers. The need of drinking water availability is rising and becoming too expensive. Various filtration techniques are available in the market. Solar desalination proves to be one of the most sustainable filtration techniques. The current work deals with the fabrication and experimentation of double slope solar still of 2m2 aperture area for portable drinking water. The composition of the water to be desalinate is not the sewage water but the normal ground water having a TDS level of more than 500PPM. The material for the basin is taken to be Fibre Reinforced Plastic (FRP) for ease in manufacturing and capability to attach to acrylic sheet for transparent walls from south east and west. The basin absorber is metallic sheet of 20 gauge. . The finding is indicate that the transparent sheet used as the walls of the still leads to higher yield and thus can further be increased if different pressure levels of 0.5 to 0.75 atm be applied.

AI-Driven Continuous Security Validation for Enterprise Linux Systems Using Configuration-as-Code
type: item
description: Enterprise Linux systems form the backbone of modern financial, healthcare, and large-scale enterprise infrastructures. These environments are required to meet strict security and compliance standards while supporting continuous operational availability. Traditional security validation approaches for Linux systems rely heavily on periodic vulnerability scans, manual audits, and reactive remediation processes, which often fail to detect configuration drift and emerging security risks in a timely manner. As system scale and complexity increase, these limitations become more pronounced, leading to delayed remediation and increased exposure to compliance violations. This paper presents an AI-driven approach for continuous security validation of enterprise Linux systems using Configuration-as-Code principles. By representing security baselines, hardening standards, and compliance controls as version-controlled configurations, the proposed approach enables consistent enforcement and validation across large Linux environments. Artificial intelligence techniques are applied to analyze configuration deviations, identify recurring misconfigurations, and prioritize remediation efforts based on risk and operational impact. Rather than replacing existing security tools, the approach augments them by providing continuous assessment and intelligent decision support. Through architectural analysis and practical observations from enterprise Linux environments, this study demonstrates how integrating AI-assisted analysis with Configuration-as-Code improves visibility, reduces configuration drift, and strengthens overall security posture. The findings suggest that continuous, automated validation can significantly enhance compliance readiness and operational resilience while reducing manual effort in large-scale Linux infrastructures.
