Raw water, sourced directly from natural water bodies, is unsuitable for direct consumption due to the presence of various impurities. Therefore, it undergoes treatment at a Water Treatment Plant (WTP) before being supplied to the public. Preliminary treatment involves the removal of floating matter, through screening, while heavier particles settle out by gravity, fine particles remain in suspension, causing turbidity. Effective removal of these suspended particles requires coagulation to form flocs and facilitate the settling. Determining the optimal coagulant dosage is crucial, as both underdoing and overdosing of coagulant can lead to ineffective treatment and increased costs. Conventionally optimum dosage of coagulant is determined by performing jar test. This study focuses on predicting the optimum coagulant dosage using two soft computing techniques: Artificial Neural Network (ANN) and Random Forest (RF). The Input parameters for model development include turbidity, pH, temperature, and alkalinity of raw water from the Parvati Water Treatment Plant, Pune. In this study Four models were developed, namely Model A (Turbidity), Model B (pH, Alkalinity, Temperature, Turbidity), Model C (pH, Alkalinity, Temperature), and Model D (Alkalinity and Turbidity). These models were trained using ANN and RF. Predictions of optimum coagulant doses were made for the testing dataset, and model accuracy was evaluated using Scatter plots, Root Mean Squared Error (RMSE) and Coefficient of Correlation (R). Results indicate that RMSE values of ANN Models are comparatively lower than RF. Comparing among Models A, B, C, and D, Model B and Model D exhibit better performance, with lower RMSE values.
原水直接取自天然水体,由于含有各种杂质,不适合直接饮用。因此,在向公众供水之前,需要在水处理厂(WTP)进行处理。初步处理包括通过筛选去除漂浮物,较重的颗粒会在重力作用下沉降,而细小的颗粒则会悬浮在水中,造成浑浊。要有效去除这些悬浮颗粒,就需要进行混凝处理,以形成絮凝体,促进沉降。确定最佳的混凝剂用量至关重要,因为混凝剂用量不足或过量都会导致处理效果不佳和成本增加。通常情况下,混凝剂的最佳用量是通过进行罐子试验来确定的。本研究的重点是使用两种软计算技术预测混凝剂的最佳用量:人工神经网络(ANN)和随机森林(RF)。模型开发的输入参数包括浦那 Parvati 水处理厂原水的浊度、pH 值、温度和碱度。本研究开发了四个模型,即模型 A(浊度)、模型 B(pH 值、碱度、温度、浊度)、模型 C(pH 值、碱度、温度)和模型 D(碱度和浊度)。这些模型均使用 ANN 和 RF 进行了训练。对测试数据集的最佳混凝剂剂量进行了预测,并使用散点图、均方根误差(RMSE)和相关系数(R)对模型的准确性进行了评估。结果表明,ANN 模型的 RMSE 值相对低于 RF。与模型 A、B、C 和 D 相比,模型 B 和模型 D 的性能更好,RMSE 值更低。

This case study focuses on the groundwater level tanks (GLR) located in Netra Village, 35 km from Jodhpur, on Nagour Road. The investigation revealed that people and livestock in the area were grappling with water scarcity issues. Non-Destructive Testing (NDT) methods were employed to assess the residual strength of three tanks in the region. The results showed that Tank-1 had a residual strength of 35.41%, Tank-2 had 63.08%, and Tank-3 had 53.8%. Alkali-silica reaction (ASR) poses a significant threat to the structural integrity of concrete tanks, necessitating accurate and non-destructive methods for residual strength assessment. This research paper delves into the effectiveness of NDT methods, specifically rebound hammer and Ultrasonic Pulse Velocity (UPV), in evaluating the residual strength of ASR-affected tanks. Through an extensive review of literature, case studies, and experimental data, this study aims to shed light on the practical application of rebound hammer and UPV for ASR assessment in tank structures. The paper discusses the principles, advantages, and limitations of each NDT method, emphasizing their ability to detect ASR-induced damage and predict the remaining structural capacity of tanks. Moreover, the research addresses the challenges associated with implementing rebound hammer and UPV techniques in ASR-affected environments, offering recommendations for enhancing their reliability and accuracy. By harnessing the combined capabilities of rebound hammer and UPV, engineers and asset managers can make well-informed decisions regarding the maintenance, repair, and retrofitting of ASR-affected tanks, ensuring their long-term safety and functionality in critical infrastructure applications.
本案例研究的重点是位于内特拉村的地下水位蓄水池(GLR),该村距离焦特布尔 35 公里,位于纳古尔路(Nagour Road)上。调查显示,该地区的居民和牲畜都面临着缺水问题。采用无损检测(NDT)方法评估了该地区三个水箱的剩余强度。结果显示,1 号水箱的残余强度为 35.41%,2 号水箱的残余强度为 63.08%,3 号水箱的残余强度为 53.8%。碱硅反应(ASR)对混凝土储罐的结构完整性构成重大威胁,因此有必要采用准确、无损的方法来评估残余强度。本研究论文深入探讨了无损检测方法,特别是回弹仪和超声波脉冲速度 (UPV) 在评估受 ASR 影响的储罐残余强度方面的有效性。通过广泛查阅文献、案例研究和实验数据,本研究旨在阐明回弹仪和 UPV 在储罐结构 ASR 评估中的实际应用。论文讨论了每种无损检测方法的原理、优势和局限性,强调了它们检测 ASR 引起的损坏和预测储罐剩余结构容量的能力。此外,研究还探讨了在受 ASR 影响的环境中实施回弹仪和 UPV 技术所面临的挑战,并就如何提高其可靠性和准确性提出了建议。通过利用回弹仪和 UPV 的综合能力,工程师和资产管理人员可以就受 ASR 影响的储罐的维护、修理和改造做出明智的决策,确保其在关键基础设施应用中的长期安全性和功能性。

Drowsiness detection is a solution for identifying signs of fatigue or sleepiness in individuals. One of the key features of our model is that it can detect drowsiness at night as well using Mobile cameras (infrared sensors). The system captures infrared images of the person's face and analyzes the physiological and behavioral cues related to drowsiness. Infrared sensors allow for drowsiness detection in low-light conditions, making it particularly useful for night-time scenarios such as night driving. The system can trigger alerts or interventions if drowsiness is detected, helping to prevent accidents or mistakes. We will be using libraries like OpenCV, TensorFlow, CNN, and VGG19 features in our model. By combining the accessibility of Android devices with the advanced capabilities of the Deep Learning algorithm, drowsiness detection using infrared sensors has the potential to greatly improve the safety and productivity of individuals in their daily lives.

Fabrication of CDS/CDTE based heterojunction photovoltaic cell has been undertaken to explore better light conversion efficiency. We have developed a photovoltaic cell using glass coated with Indium doped Tin Oxide (ITO) which works as transparent conducting oxide (TCO). ITO coated glass has promising prospects of enhancing the efficiency of the photovoltaic cell. ITO layers are known to be employed as anode terminal due to the negative polarity they possess compared to the whole PV cell; here, we have employed it for the same function as the front layer. During fabrication of the photovoltaic cell, the deposition of nanoparticles of CDS and CDTE layer is undertaken through doctor-blade method. We have employed pure CDS as window layer for its high band gap of 3.8 eV (particle size: 8 nm) and CDTE as absorber layer due to its high optical absorption coefficient with high mobility, good carrier lifetime and enhanced crystallographic properties. The CDS window layer and CDTE absorber layer together constitute a p-n junction where the CDS window layer captures high intensity photons and transmits the photo-excited electron to CDTE absorber layer, thereby leading to photo-current output, which serves as a base to explore and test its further applications. To obtain band gap of respective CDTE and CDS nanoparticles, optical characterization is used. Silver paste is used as rear contact to form anode terminal having good conductivity and providing better mechanical support to the photovoltaic cell.

Fraud in any financial transactions causes severe loss to both customer as well as the seller. The loss is not confined to financial loss only but it also causes severe dent to the confidence of the customer especially related to shopping platform and the payment instrument used. Nowadays a substantial part of buying and selling of goods and services are taking place using various e commerce platforms. Many customer use credit card as payment instrument. During the payment process, users do exposes the credit card credentials to the payment platform. These payment platforms are vulnerable to fishing and hacking attackers and the payment instrument remains highly susceptible to fraudulent activities. There are two approaches to dealing with this problem. The first step is to identify the fraudulent activities and second step is to prevent any such attempt of fraud. This paper proposes a model based on machine learning algorithms to identify fraudulent attempts by analyzing credit card transactions data set and proposes methods of preventing such fraud activities. The paper also presents the accuracy of this AI model in identifying and preventing fraudulent and mischievous activities.
