Energy Audit, in general, is the process of turning conservation concepts into reality by combining technically possible solutions with cost-effective organization within a set time limit. Auditing has grown in importance in recent decades because of its numerous advantages, including low maintenance and environmental benefits. The main goal is to lower the cost of energy use per unit. It serves as a benchmark for managing energy in an organization as well as a foundation for planning the most efficient use of energy. This proposed project examines the economic viability of replacing legacy equipment with modern technology like python, as well as calculating the return-on-investment period and doing research in Bapatla Engineering College, India.
一般来说,能源审计是在规定的时间内将技术上可行的解决方案与具有成本效益的组织相结合,将节约概念变为现实的过程。近几十年来,审计越来越重要,因为它有许多优点,包括低维护和环境效益。主要目标是降低每单位能源的使用成本。它是组织管理能源的基准,也是规划最有效利用能源的基础。这个拟议中的项目考察了用蟒蛇等现代技术取代传统设备的经济可行性,并计算了投资回报率,并在印度巴帕特拉工程学院进行了研究。

Micro Grids are going to replace the traditional concept of electrical networks in order to satisfy the increasing needs in terms of flexibility, accessibility, reliability, and quality of the power supply. Economy and energy efficiency are the paradigms followed to exploit the available distributed energy resources (DERs), guaranteeing technical and environment-friendly standards. Obviously, the path to Micro Grids is complicated by the increasing heterogeneity of Micro Grid components, such as renewable, storage systems, fossil- fueled generators, and controllable loads [1]. Fortunately, the synergic interaction between DERs and information and communication technologies (ICT) foster the coordination among different infrastructures, promoting the development of Smart Grids at both theoretical and practical levels. The major highlights of utilizing micro grid are the capacity to self-heal from power quality (PQ) issues, efficient energy management, incorporation of automation based on ICT and smart metering, integration of distributed power generation, renewable energy resources, and storage units [2]. The advantages contribute to maintain good PQ and to maintain the reliability. In this regard, the concept of micro grid is brought to the stage as one of the main building blocks of the future smart grids [3].
微电网将取代传统的电网概念,以满足人们对电力供应的灵活性、可及性、可靠性和质量日益增长的需求。经济和能源效率是开发可用分布式能源(DERs)所遵循的范例,保证了技术和环境友好标准。显然,微电网组件(如可再生能源、存储系统、化石燃料发电机和可控负载)的异质性日益增加,使得微电网的发展道路变得复杂[1]。幸运的是,分布式电网和信息通信技术(ICT)之间的协同互动促进了不同基础设施之间的协调,在理论和实践层面促进了智能电网的发展。利用微电网的主要亮点是电能质量(PQ)问题的自愈能力、高效的能源管理、基于ICT和智能计量的自动化集成、分布式发电、可再生能源和存储单元的集成[2]。这些优点有助于保持良好的PQ和可靠性。因此,微电网的概念作为未来智能电网的主要组成部分之一被提上了舞台[3]。

由于泰米尔纳德邦应用科学学院的行为增加,入学价格的竞争水平也增加了。通过实施一些动态策略,只有学术引进才能适应自身的竞争。一项调查清楚地表明,超过75%的工程学院的招生人数不足实际招生人数的30%。因此,监视是疯人院的工作。另一项调查显示,每年有10%的应用科学学院因缺乏准入而关闭,5%的工程学院因缺乏实力而决定出售。在机构制定的强有力的努力和动态策略下,被提名人只有在自己的取向完全匹配的情况下才能被机构录取,否则候选人将继续按照偏好列表中的下一个候补人选选择[1]。本文明确强调了一些影响因素,以确定使簿记员的效力至少达到盈亏平衡点的模式。此外,网络空间中的大众万维网在存储、分割和分发学术创新数据方面发挥着重要作用。一项社会调查表明,超过65%的招生是通过他们有效的网络页面获得的。万维网的指数个体发展为利用www登录日志研究大学生及其行为提供了广阔的前景。如果一个机构的网络领域清楚地包含了潜在教育所需的信息,那么他们当然可以吸引以上这些人,这样他们就可以在我们的管辖范围之外获得更多的录取。[2]一些潜在的学生在访问网站时获得录取的吸引力是:通过点击最小的点击量来获得所需的信息,在访问和浏览大学的万维网网站时没有网络流量。通过实施搜索机车优化、搜索引擎蜘蛛的实践,在短时间内对搜索讯问进行整改。始终使用最快和最新的浏览器和操作系统,在浏览大学网站时不要显示更多的网络服务器错误。对于吸引辅导班和其他州立学生来说,这一网络在托马斯·纳尔逊·佩奇的剑术上发挥了重要作用。万维网的使用是数据挖掘技术的实际应用,对非常大的数据储量进行选择模式辐射图。一般来说,每个万维网服务器都有一个记录簿,记录潜在学生需要的所有名词交易的同义词/下义词(按估计频率排序),并作为潜在学生和介绍之间的桥梁。记录包含了满月月相的偶然事件,每个用户点击到纠缠文档的纠缠站点。对细节的有用记录需要仔细检查和推断,以收集有关实际潜在学生及其家长访问www页面的偏好的知识。近年来,人们提出了几种挖掘web对数数据的方法。本课题的主要目的是利用泊松统计分布分析的统计方法来突破高概率的会话事件,并将我们开发的算法与泊松值的效率进行比较。海量点击流数据的学科领域要求采用数据挖掘方法。对web主机的记录进行数据挖掘,包含了频繁出现的访问序列的确定。毒物分布的统计方法清楚地表明,当一个单一的自然事件的规范概率已知时,特定后果的经常发生的概率。在此,将毒性值的概率与我们所开发的算法的效率进行了比较。对于更多比特的事务,我们开发的算法其性能优于毒值[3]。因为我们的算法将权威层提取为依赖而不是独立的。本文使用泊松分布独立地求出用户访问特定页面的概率频率,但所开发的算法的结果是相关的

At present most of the larger companies depends heavily on their data science capabilities for taking decisions. On the basis of complexity and diversity of analysis, the big data units are transformed into larger and more technologies. Internet technologies are now playing a vital role in our day to day life. It has the advantages along with the disadvantages also, which in term generates the requirements of image hiding technology for maintaining the secrecy of the secret information. The interpretability of findings plays a major role for the success of delivering data science solutions into business reality. Even if the existing method provides outstanding accuracy, they may be neglected if they do not hide the image or text in an exact manner for various cases. When evaluating ML/DL [1] models there is an excess of possible metrics to assess performance. There are things like accuracy, precision- recall, ROC and so on. All of them can be useful, but they can also be misleading or don't answer the question at hand very well. The ROC AUC score is not informative enough for taking decisions since it is abstract for non-technical managers. Hence two more informative and meaningful metrics that every analyst should take into consideration when illustrating the results of their binary classification models: Cumulative Gains and Lift charts. Both the metrics are extremely useful to validate the predictive model (binary outcome) quality. Gain and Lift charts [2] are used to update the performance of binary classification model. They measure how much better one can expect to do with the predictive model. It also helps to find the best predictive model among multiple challenger models. The main intention behind this paper is to assess the performance of the binary classification model and compares the results with the random pick. It shows the percentage of gains reached when considering a certain percentage of the data set with the highest probability to be target according to the classifier. This paper proposes a broad look at the ideas of cumulative gains chart and lift chart to develop a binary classifier model quality which can be used theoretically to evaluate the quality of a wide range of classifiers in a standardized fashion. This paper proposes a hybrid solution of image hiding binary classifier using vicinity value based image hiding classification model as main complimented by gain calculation to increase image hiding classification accuracy. The study has shown that implementing the image hiding binary classification using Gain and Lift is feasible. Experiment of the study has confirmed that the image hiding binary classification model can be improved.
目前,大多数大公司都严重依赖于他们的数据科学能力来做出决策。在分析的复杂性和多样性的基础上,将大数据单元转化为更大、更多的技术。互联网技术现在在我们的日常生活中起着至关重要的作用。它有优点也有缺点,这就产生了对图像隐藏技术对保密信息保密性的要求。结果的可解释性对于将数据科学解决方案成功地交付到商业现实中起着重要作用。即使现有的方法提供了出色的准确性,如果它们不能在各种情况下以精确的方式隐藏图像或文本,它们也可能被忽略。在评估ML/DL[1]模型时,有过多的可能的指标来评估性能。比如准确度,查全率,ROC等等。所有这些都是有用的,但它们也可能具有误导性,或者不能很好地回答手头的问题。ROC AUC分数对于决策来说没有足够的信息,因为它对于非技术管理人员来说是抽象的。因此,在说明二元分类模型的结果时,每个分析师都应该考虑两个更有信息和有意义的指标:累积收益和提升图。这两个指标对于验证预测模型(二元结果)质量都非常有用。增益图和升力图[2]用于更新二元分类模型的性能。它们衡量的是人们对预测模型的期望能提高多少。它还有助于在多个挑战者模型中找到最佳的预测模型。本文的主要目的是评估二元分类模型的性能,并将结果与随机选择进行比较。它显示了根据分类器考虑具有最高概率的数据集的一定百分比作为目标时所达到的增益百分比。本文广泛地借鉴累积增益图和提升图的思想,建立了一个二元分类器模型质量,该模型质量可以在理论上以标准化的方式评价各种分类器的质量。为了提高图像隐藏的分类精度,提出了一种以基于邻近值的图像隐藏分类模型为主体,结合增益计算的图像隐藏二分类器混合方案。研究表明,利用增益和提升实现图像隐藏二值分类是可行的。实验结果表明,该方法可以对图像隐藏二值分类模型进行改进。

A recommendation system is an application that can identify entities of interest for a person and provide suggestions based on the past record of person’s likes and preferences. The entity of interest can be anything, for example it can be a product, a movie or a news article. Recommender system is an effective way to help users to obtain the personalized and useful information. However, due to complexity and dynamic, the traditional recommender system cannot work well in mobile environment. Keeping such things into consideration, this recommendation system aims to recommend restaurants to users using their past preferences so they do not need to go through a list of choices. The recommender system adopts a user preference model by using the features of user's visited restaurants, and utilizes the location information of user via GPS(Global Positioning System) using LBS(Location Based System) and restaurants to dynamically generate the recommendation results using collaborative filtering technique. The suggestions will be based on the user preferences obtained from the past ratings and reviews given by the user, frequently visited cuisines of the user and the time preference of the user. Moreover, a brief analysis of reviews is also made to provide user a computed synopsis of the restaurant using text mining algorithm.
推荐系统是一种应用程序,它可以识别一个人感兴趣的实体,并根据人们过去的喜欢和偏好记录提供建议。感兴趣的实体可以是任何东西,例如它可以是一个产品,一部电影或一篇新闻文章。推荐系统是帮助用户获取个性化、有用信息的有效途径。然而,传统的推荐系统由于其复杂性和动态性,在移动环境下不能很好地工作。考虑到这些因素,这个推荐系统的目的是根据用户过去的偏好向他们推荐餐馆,这样他们就不需要浏览一个选择列表。推荐系统利用用户去过的餐厅特征,采用用户偏好模型,利用LBS(location Based system)和餐厅的位置信息,利用用户通过GPS(Global Positioning system)获取的位置信息,通过协同过滤技术动态生成推荐结果。这些建议将基于用户从过去的评分和评论中获得的用户偏好、用户经常光顾的菜系以及用户的时间偏好。此外,还对评论进行了简要分析,并使用文本挖掘算法为用户提供了餐厅的计算摘要。

Educating and learning modalities in virtual and customary classes can be best seen as a marker of proficiency and college adequacy. The examination decides the adequacy of online and traditional classes to the College of Business and Accountancy. The respondents were the 208 understudies from the University of Cebu Lapu and Mandaue utilizing the descriptive - comparative research method on a snowball sampling. Frequency and simple percentage, Mean, Chi- Square Test of Independence and Independent Samples T-test were utilized, to sum up, separate, and unwind the information assembled. The findings revealed that there is statistically significant difference on the level of effectiveness between online and traditional class. The understudies perceived online class as moderately effective while perceiving traditional class as highly effective. Moreover, it revealed that there is a statistically significant correlation on the respondents gender, course and year level on the level of perception either by traditional or online classes. The study concludes that Online and Traditional modalities of educating and learning extraordinarily assume an essential function on an understudy's useful term in school. However, refinement of approaches to these modalities is very important to portray student-teacher resiliency at any given situation.

Mobile Ad-hoc Network is a wireless mobile nodes network, which forms a network without any pre existing fixed network infrastructure support. MANET permits versatile communication between hosts that are moving around. MANETs have numerous advantages compared to traditional wireless networks. In MANET, each mobile node needs the cooperation of other nodes in the network for forwarding data packets from source to destination node. Mobile Ad-hoc Network includes different routing protocols for communication and in MANET each mobile node can act as host as well as sender or receiver at the same time. MANET is design to smartly react to network changes and operates without human interference to support nodes mobility. Mobile Ad-hoc Networks are designed to sustain its survivability in unfriendly and hostile conditions such as natural disasters and other emergency conditions. However unique characteristics of MANETs topology such as open peer-to-peer architecture, dynamic network topology, shared wireless medium and limited resource (battery, memory and computation power) pose a number of non-trivial challenges to security design. These challenges and characteristics require MANETs to provide broad protection and desirable network performance. Due to dynamic nature of MANET it is very challenging work to employ a secure route. The routing protocols play important role in transferring data. Mobile Ad Hoc Networks (MANETs) pose challenges in terms of energy control, due to their fixed transmission power, the mobility of nodes and a constantly changing topology. High levels of energy are needed in wireless networks, particularly for routing. In order to address this problem, energy enhancement is analyzed with the proposed dynamic AODV cluster base trust protocol, with the aim of maximizing the lifetime of the network. We have performed simulation of our approach to justify our research work on network simulator-2 (NS-2). Simulation result presents that our proposed approach result is improved the performance of network than the existing Mobile Ad hoc Network protocol.
移动自组织网络是一种无线移动节点网络,它不需要任何预先存在的固定网络基础设施的支持而形成网络。MANET允许在四处移动的主机之间进行通用通信。与传统的无线网络相比,manet具有许多优点。在MANET中,每个移动节点需要网络中其他节点的配合才能将数据包从源节点转发到目的节点。移动自组织网络包括不同的通信路由协议,在MANET中,每个移动节点可以同时充当主机以及发送方或接收方。MANET旨在智能地响应网络变化,并在没有人为干扰的情况下运行,以支持节点的移动性。移动自组织网络旨在维持其在不友好和敌对条件下的生存能力,如自然灾害和其他紧急情况。然而,无线无线网络拓扑结构具有开放的点对点结构、动态的网络拓扑结构、共享的无线介质和有限的资源(电池、内存和计算能力)等独特的特性,对安全设计提出了许多严峻的挑战。这些挑战和特点要求manet提供广泛的保护和理想的网络性能。由于MANET的动态特性,采用安全路由是一项非常具有挑战性的工作。路由协议在数据传输中起着重要的作用。移动自组织网络(manet)由于其固定的传输功率、节点的移动性和不断变化的拓扑结构,在能量控制方面提出了挑战。无线网络需要大量的能量,尤其是在路由方面。为了解决这一问题,利用提出的动态AODV集群基础信任协议进行能量增强分析,以最大化网络生命周期为目标。我们已经对我们的方法进行了模拟,以证明我们在网络模拟器-2 (NS-2)上的研究工作是正确的。仿真结果表明,与现有的移动自组网协议相比,该方法的网络性能得到了提高。

Tomatoes are the most commonly grown crop globally, and they are used in almost every kitchen. India holds second place in the production of tomatoes. Due to the various kinds of diseases, the quantity and quality of tomato crop go down. Identifying the diseases in the earlier stage is very important and will help the farmers save the crop. The first initial step is pre-processing, for the Canny edge detection method is used for detecting the edges in the tomato leaves. The classification of tomato leaves is to be carried out by extracting the features like color, shape, and texture. Extracted features from segmented images are fed into classification. The convolutional neural network algorithm will be used, which will give a better accuracy to classify the diseases in the tomato leaves.

Voting is a critical element of any election which involves the processes of electing leaders or representatives into positions of authority in a democratic system of government. In most developing countries of the world, this process is usually marred with challenges of confidentiality, Integrity, availability and auditability such as falsification of results, identity theft, stolen of ballot boxes, multiple voting problems, over voting, and electoral fraud. This paper presents a framework for Automated Teller Machine-based voting system that solves the aforementioned challenges of the current voting system by using the existing Automated Teller Machines and debit cards issued for voting. Going further to implement the solution proposed in this paper will enhance and guarantee the credibility of the electoral processes and show a true reflection of the wishes of the people.
投票是任何选举的关键因素,在民主政府制度中选举领导人或代表担任权力职位的过程中。在世界上大多数发展中国家,这一过程通常受到保密性、完整性、可用性和可审计性方面的挑战,如伪造结果、身份盗窃、投票箱被盗、多重投票问题、过度投票和选举欺诈。本文提出了一个基于自动柜员机的投票系统框架,通过使用现有的自动柜员机和为投票而发行的借记卡,解决了当前投票系统的上述挑战。进一步执行本文件提出的解决办法将加强和保证选举进程的可信性,并真正反映人民的愿望。
