The proposed method seeks to assist Indian pleasant in selecting the optimum crop to produce based on the characteristics of the soil as well as external factors like temperature and rainfall by using an intelligent system called Crop Recommender. The Indian economy is significantly impacted by the agricultural sector. Whether publicly or covertly, the bulk of Indians are relying on agriculture for their living. As a result, it is undeniable that agriculture is significant to the country. The majority of Indian farmers believe that they should trust their intuition when deciding on a crop to grow in a particular season or they simply employ the methods they have been doing from the beginning of time. They are more at ease just adhering to conventional agricultural practices and standards than truly appreciating how crop yield is influenced by the present weather and soil conditions. The farmer can unintentionally lose money if he makes one bad decision, which would hurt both him and the surrounding agricultural industry. As the agriculture business is the foundation of the entire lateral system. Using the machine learning algorithm, this problem can be resolved. A crucial perspective for identifying a practical and workable solution to the crop production issue is machine learning (ML). Machine learning (ML) may predict a target or outcome from a set of predictors using supervised learning. A recommendation system is implemented using decision trees. The major goals of this system are to provide farmers with recommendations regarding the best crops to sow based on their soil and local rainfall patterns. We have employed the Random Forest Machine Learning technique to forecast the crop. Crop prediction is assessing the crop based on historical data from the past that includes elements like temperature, humidity, ph, and rainfall. It gives us a broad picture of the best crop that can be raised in light of the current field weather conditions. These predictions can be made by Random Forest, a machine learning technique. The highest level of accuracy, up to 90%, will be possible for crop predictions. The random forest algorithm achieved the accuracy about 99.03%.
所提出的方法旨在帮助印度人根据土壤特征以及温度和降雨等外部因素,使用一个名为作物推荐器的智能系统,选择最合适的作物来生产。印度经济受到农业部门的重大影响。无论是公开的还是秘密的,大多数印度人都依靠农业为生。因此,农业对国家的重要性是不可否认的。大多数印度农民认为,在决定在特定季节种植作物时,他们应该相信自己的直觉,或者他们只是采用他们从一开始就采用的方法。他们更乐于坚持传统的农业实践和标准,而不是真正了解当前天气和土壤条件对作物产量的影响。如果农民做了一个错误的决定,他可能会在无意中损失金钱,这将损害他和周围的农业产业。由于农业经营是整个横向体系的基础。使用机器学习算法,可以解决这个问题。确定农作物生产问题的实际可行解决方案的一个关键视角是机器学习(ML)。机器学习(ML)可以使用监督学习从一组预测器中预测目标或结果。利用决策树实现了一个推荐系统。该系统的主要目标是根据农民的土壤和当地的降雨模式,向农民提供关于播种最佳作物的建议。我们使用随机森林机器学习技术来预测作物。作物预测是根据过去的历史数据对作物进行评估,这些数据包括温度、湿度、ph值和降雨量等因素。它为我们提供了在当前田间天气条件下可以种植的最佳作物的大致情况。这些预测可以通过随机森林来实现,这是一种机器学习技术。农作物预测的准确率最高可达90%。随机森林算法的准确率约为99.03%。

Ovarian cancer remains a leading cause of cancer-related mortality among women worldwide. Traditional diagnostic methods often lack the precision required for early detection and accurate subtype classification. In this study, we address the challenge of automating ovarian cancer diagnosis by introducing Attention-Based Models (ABMs) in combination with 3D Convolutional Neural Networks (CNNs). Our research seeks to enhance the accuracy and efficiency of ovarian cancer diagnosis, particularly in distinguishing between serous, mucinous, and endometrioid subtypes. Conventional diagnostic approaches are limited by their reliance on manual interpretation of medical images and fail to fully exploit the rich information present in MRI scans. The proposed work leverages ABMs to dynamically focus on critical regions in MRI scans, enabling enhanced feature extraction and improved classification accuracy. We demonstrate our approach on a well-curated dataset, OvaCancerMRI-2023, showcasing the potential for precise and automated diagnosis. Experimental results indicate superior performance in cancer subtype classification compared to traditional methods, with an accuracy of 94% and F1 score of 0.92. Our findings underscore the potential of ABMs and 3D CNNs in revolutionizing ovarian cancer diagnosis, paving the way for early intervention and more effective treatment strategies. In conclusion, this research marks a significant advancement in the realm of ovarian cancer diagnosis, offering a promising avenue for improving patient outcomes and reducing the burden of this devastating disease. The integration of ABMs and 3D CNNs holds substantial potential for enhancing the accuracy and efficiency of ovarian cancer diagnosis, particularly in subtyping, and may contribute to early intervention and improved patient care.

The primary function of a crude distillation unit (CDU) within a petroleum refinery is to effectively segregate crude oil into its constituent fractions or products based on their respective boiling points. The Crude Distillation column often serves as the primary processing unit within most refineries, pivotal in producing a wide range of refinery products. This study examines research articles published between 2013 and 2023 that specifically investigate issues related to crude distillation units. The research endeavours to produce innovative designs and construct mathematical models to enhance production efficiency within this context. The research primarily centres on developing a mathematical model that accurately characterizes the distillation tower. This is achieved using either an Artificial Neural Network or a nonlinear model predictive control approach. The primary objective of simulation and optimization research is identifying optimal operating conditions, typically employing software tools such as Aspen HYSYS or PRO II. The corrosion treatment outcomes conducted at the tower's upper section were satisfactory. The study focused on the issue of corrosion in the overhead lines and pumps around exchangers. This design research aims to investigate potential modifications to the distillation tower's design or preflash process to optimize production outcomes.

Like other types of buildings, shopping mall buildings in Nigeria receive insufficient maintenance attention. The vast majority of shopping malls exhibit awful structural and aesthetic conditions of deterioration. This study, therefore, aims to investigate the maintenance practices of shopping malls with a view to addressing issues that arise from factors responsible for the deterioration of the building fabrics and components. Data from 97 building maintenance stakeholders from Lagos Island and Mainland malls were gathered using a cross-sectional survey utilizing two sets of structured self-administered questionnaires. The results revealed 31 maintenance practices implemented in shopping malls. The study also uncovered 21 key factors influencing the sourcing decision of maintenance practices in shopping malls. Besides, the results further revealed 22 causative factors that lead to the deterioration of shopping mall building fabrics and components. The study comes to the conclusion that regardless of the sourcing decision, other factors, such as quality and frequency of maintenance, have a significant impact on how quickly a shopping mall deteriorates. It is recommended that maintenance stakeholders should play active roles in ensuring shopping malls are adequately maintained. This may be achieved by developing a defined strategy for routine and preventive maintenance.
与其他类型的建筑一样,尼日利亚的购物中心建筑没有得到足够的维护重视。绝大多数购物中心的结构和美观状况都很糟糕。因此,本研究旨在探讨商场的维修保养方法,以解决造成建筑物结构和构件老化的因素所产生的问题。来自拉各斯岛和大陆购物中心的97个建筑维护利益相关者的数据是通过使用两套结构化自我管理问卷的横断面调查收集的。调查结果揭示了商场实施的31项维修措施。该研究还揭示了21个影响商场维修实践采购决策的关键因素。此外,研究结果进一步揭示了22个导致商场建筑结构及构件劣化的因素。该研究得出的结论是,无论采购决策如何,其他因素,如质量和维修频率,对购物中心的退化速度有重大影响。我们建议保养商应积极参与,确保商场得到妥善保养。这可以通过制定常规和预防性维护的明确策略来实现。

This article put forward the determination of the optimal siting and sizing of capacitor banks and PV-DG (Photo-Voltaic Distribution Generation) units in a radial distribution system. A modern population-based optimization algorithm, Hunter-Prey Optimization (HPO), is applied to determine the optimal capacitor bank and PV-DG placement. This algorithm, HPO, got its motivation from the trapping behaviour of the carnivore (predator/hunter) like lions and wolves towards their target animal like deer. The typical IEEE-33 & 69 test bus systems are scrutinized for validating the effectiveness of the suggested algorithm using MATLAB software R2021b version. The acquired results are collated with the existing heuristic algorithms for the active power loss criterion. The nominal or base values for system losses and voltage profile were considered for the comparison, with the results from HPO. The HPO application has an efficient performance in figuring out the most favourable location and capacity of the capacitor banks and PV DGs compared with the other techniques.
本文提出了径向配电系统中电容器组和PV-DG(光伏配电发电)单元的最佳选址和尺寸的确定。采用基于种群的现代优化算法——猎人-猎物优化算法(HPO)来确定最佳电容器组和PV-DG的放置位置。这个算法,HPO,从像狮子和狼这样的食肉动物(捕食者/猎人)对鹿这样的目标动物的诱捕行为中得到了它的动机。典型的IEEE-33使用MATLAB软件R2021b版本对69个测试总线系统进行了仔细检查,以验证所建议算法的有效性。所得结果与现有的有功损耗准则的启发式算法进行了比较。为了与HPO的结果进行比较,考虑了系统损耗和电压分布的标称值或基本值。与其他技术相比,HPO应用在确定电容器组和光伏dg的最佳位置和容量方面具有有效的性能。

This article reviews the physical conditions that natural, turbulent flows meet to be considered in “Dynamic Equilibrium”, a condition that greatly facilitates the analysis of flows, thanks to the concept of “equiprobability”, in such a way that the tracer dyes can give an essential information of the dynamics of the current. A general State Function is proposed for this dynamic, which allows to study Advection and Dispersion for virtually all types of river beds, achieving a series of compact and precise relationships, both in hydraulics and thermodynamics. This approach allows us to obviate the limiting use of non-linear differential equations, as "mandatory" characterization of fluid dynamics. With this new method, a practical case from the technical literature is analyzed, and it is solved in detail, comparing it with the classic method of Statistical Moments. Conclusions on results, and recommendations are made.

Predicting protein secondary structure based on ensemble Neural Network 基于集成神经网络的蛋白质二级结构预测
Pub Date : 2021-02-15 DOI: 10.5935/JETIA.V7I27.732

Protein structure prediction is very vital to innovative process of discovering new medications based on the knowledge of a biological target. It is also useful for scientifically exposing the biological basis of convoluted diseases and drug effects. Despite its usefulness, protein structure is very complex, thereby making its prediction to be arduous, timewasting and costly. These drawbacks necessitated the need to develop more effective techniques with high prediction capability. Conventional techniques for predicting protein structure are ineffective, perform poorly, expensive and slow. The reasons for these are due to the vague dissimilar sequences among protein structures, meaningless protein data, high dimensional data, and having to deal with highly imbalanced classification task.  We proposed an Ensemble Neural Network learning model that consists of some Neural Network algorithms such as Feed Forward Neural Network (FFNN), Recurrent Neural Network (RNN), Cascade Forward  Network (CFN) and Non-linear Autoregressive Network with Exogenous (NARX) models.

蛋白质结构预测对于基于生物靶点知识发现新药物的创新过程至关重要。它也有助于科学地揭示复杂疾病和药物作用的生物学基础。尽管它很有用,但蛋白质结构非常复杂,因此对其进行预测是一项艰巨、耗时和昂贵的工作。这些缺点使得需要开发具有高预测能力的更有效的技术。预测蛋白质结构的传统技术效率低、性能差、昂贵且速度慢。其原因是由于蛋白质结构之间的不相似序列模糊,蛋白质数据无意义,数据高维,分类任务高度不平衡。提出了一种集成神经网络学习模型,该模型由前馈神经网络(FFNN)、递归神经网络(RNN)、级联前向网络(CFN)和外生非线性自回归网络(NARX)等神经网络算法组成。使用Levenberg-Marquardt (LM)、弹性反向传播(RBP)和缩放共轭梯度(SCG)等训练算法对这些模型进行训练以提高性能。实验结果表明,与其他模型相比,我们提出的模型具有更好的性能。

It is also useful for scientifically exposing the biological basis of convoluted diseases and drug effects. Despite its usefulness, protein structure is very complex, thereby making its prediction to be arduous, timewasting and costly. These drawbacks necessitated the need to develop more effective techniques with high prediction capability. Conventional techniques for predicting protein structure are ineffective, perform poorly, expensive and slow. The reasons for these are due to the vague dissimilar sequences among protein structures, meaningless protein data, high dimensional data, and having to deal with highly imbalanced classification task.  We proposed an Ensemble Neural Network learning model that consists of some Neural Network algorithms such as Feed Forward Neural Network (FFNN), Recurrent Neural Network (RNN), Cascade Forward  Network (CFN) and Non-linear Autoregressive Network with Exogenous (NARX) models.

In the current scenario, Intelligent Transportation Systems play a significant role in smart city platform. Automatic moving vehicle detection from video sequences is the core component of the automated traffic management system. Humans can easily detect and recognize objects from complex scenes in a flash. Translating that thought process to a machine, however, requires us to learn the art of object detection using computer vision algorithms. This paper solves the traffic issues of the urban areas with an intelligent automatic transportation system. This paper includes automatic vehicle counting with the help of blob analysis, background subtraction with the use of a dynamic autoregressive moving average model, identify the moving objects with the help of a Boundary block detection algorithm, and tracking the vehicle. This paper analyses the procedure of a video-based traffic congestion system and divides it into greying, binarisation, de-nosing, and moving target detection. The investigational results show that the planned system can provide useful information for traffic surveillance.
在当前的场景中,智能交通系统在智慧城市平台中扮演着重要的角色。基于视频序列的移动车辆自动检测是自动交通管理系统的核心组成部分。人类可以很容易地在一瞬间从复杂的场景中检测和识别物体。然而,将这种思维过程转化为机器,需要我们学习使用计算机视觉算法检测物体的艺术。本文用智能自动交通系统解决了城市交通问题。本文包括基于blob分析的车辆自动计数,基于动态自回归移动平均模型的背景减除,基于边界块检测算法的运动目标识别,以及车辆跟踪。本文分析了基于视频的交通拥堵系统的实现过程,将其分为灰度化、二值化、去噪和运动目标检测四个部分。调查结果表明,该系统可以为交通监控提供有用的信息。
