Statistical machine learning models suffer poorly because of class imbalance issue. Real world dataset contains mostly ‘normal’ examples and very few ‘abnormal’ examples and in most of the cases, the primary goal is to identify the abnormal instances. For example, if we want to develop a statistical machine learning model to identify financial fraud using the historical transaction data then we can expect that majority of the data comes from normal/non-fraudulent class, whereas very few examples are fraudulent transactions. Using such imbalanced dataset for training makes machine learning models highly biased towards majority non-fraudulent class. This way, the objective to catch fraudulent transaction instances fails and misclassifying such minority class instances often results in a much higher cost. Hence, a balanced dataset is very much required to train a sound model. Different techniques such as under sampling, oversampling, SMOTE were proposed earlier. In this paper, we propose a novel technique to generate synthetic data using genetic search algorithm. We examined the effectiveness of our proposed algorithm on different datasets and reported in section V.
统计机器学习模型由于类不平衡问题而表现不佳。现实世界的数据集主要包含“正常”示例和极少数“异常”示例,在大多数情况下,主要目标是识别异常实例。例如,如果我们想开发一个统计机器学习模型来使用历史交易数据识别金融欺诈,那么我们可以预期大多数数据来自正常/非欺诈类,而很少有示例是欺诈性交易。使用这种不平衡的数据集进行训练使机器学习模型高度偏向于大多数非欺诈类。这样,捕获欺诈性事务实例的目标就失败了,并且错误分类此类少数类实例通常会导致更高的成本。因此,需要一个平衡的数据集来训练一个健全的模型。不同的技术,如欠采样,过采样,SMOTE之前提出。本文提出了一种利用遗传搜索算法生成合成数据的新技术。我们检查了我们提出的算法在不同数据集上的有效性,并在第V节中报告。

An extremely useful mechanism in the agriculture industry for efficient crop production is spraying activities. The current spray methods are inefficient. Spraying at a variable pace is the best option in this case. The size of the tree canopy must be accurately estimated in order to spray pesticides at variable rates. Due of the diverse growing structures and different plant sizes, it is difficult. Trees are seen to have a variety of shapes and dimensions throughout the growth seasons. It is vital to take into account elements like tree height, width, diameter, and total canopy volume in order to assess this alteration. The amount of a tree’s canopy is calculated in this study utilizing ultrasonic sensors, controller and a spraying mechanism is constructed in proportion to the volume of that plant. The ultrasonic sensor, controller and spraying mechanism are all part of the system. With the aid of sensors, geometrical properties of the tree are identified. A series of experiments were carried out on samples of plants with various sizes and forms. For plant sample applications, liquid pesticide savings were greater than a traditional application. Results demonstrated no discernible difference between tree canopy volumes estimated by ultrasound sensor and by person. The procedures for variable rate spraying techniques in orchards are presented in this article. The study of the creation of cost-effective precision spraying techniques using sensor technology is the major contribution of this work. Out of all of these strategies, this study will assist in selecting and designing the most effective and affordable way for a precision sprayer.
在农业工业中,有效作物生产的一个非常有用的机制是喷洒活动。目前的喷雾方法效率低下。在这种情况下,以可变的速度喷洒是最好的选择。为了以不同的速率喷洒农药,必须准确估计树冠的大小。由于不同的生长结构和不同的植物大小,这是困难的。树木在整个生长季节都有各种各样的形状和尺寸。为了评估这种变化,考虑树的高度、宽度、直径和总冠层体积等因素是至关重要的。在本研究中,利用超声波传感器、控制器和按植物体积比例构建的喷洒机制来计算树冠的数量。超声波传感器、控制器和喷涂机构都是系统的组成部分。在传感器的帮助下,识别树的几何特性。在不同大小和形态的植物样本上进行了一系列的实验。对于植物样品应用,液体农药比传统应用节省更多。结果表明,超声传感器估算的树冠体积与人工估算的树冠体积没有明显差异。本文介绍了果园可变速率喷洒技术的应用程序。研究利用传感器技术创造具有成本效益的精密喷涂技术是这项工作的主要贡献。在所有这些策略中,本研究将有助于选择和设计最有效和负担得起的精密喷雾器。

Light Emitting Diode (LED) technology has emerged as a better alternative to conventional lighting options like incandescent lamps, CFLs, etc. It has various advantages over conventional alternatives, e.g., better efficiency, longer life, multi-colored light, fast dimming capabilities, etc. LED driver circuits are adapted to supply power to LED loads. When LEDs are supplied through the AC mains, they are required to operate at a power factor near unity, creating a need for power factor correction (PFC) in the driver circuit. Also, the driver circuit should maintain a constant voltage at the load terminal such that a flicker-free operation of the LED is obtained. Buck-boost PFC configuration, derived from the basic buck-boost converter when operated in the discontinuous current conduction mode has inherent power factor correction property. This simplifies the control of the configuration to only a single voltage control loop. Active Disturbance Rejection Control (ADRC) is based on the control law implemented with the help of estimated states which are estimated with the help of an Extended State Observer (ESO). This work is focused on extending the concept of linear ADRC (LADRC) to buck-boost PFC based LED driver circuit and to evaluate its performance.
发光二极管(LED)技术已经成为白炽灯、节能灯等传统照明选择的更好替代品。与传统替代品相比,它具有各种优势,例如,效率更高,寿命更长,多色光,快速调光能力等。LED驱动电路适用于为LED负载供电。当led通过交流电源供电时,它们需要在接近单位的功率因数下工作,这就需要在驱动电路中进行功率因数校正(PFC)。此外,驱动电路应在负载端保持恒定电压,以便获得LED的无闪烁操作。Buck-boost PFC结构是由基本Buck-boost变换器在断续电流传导模式下导出的,具有固有的功率因数校正特性。这简化了配置的控制,只有一个电压控制回路。自抗扰控制(ADRC)是一种基于估计状态实现的控制律,该控制律借助于扩展状态观测器(ESO)进行估计。本研究的重点是将线性自抗扰控制器(LADRC)的概念扩展到基于压升压PFC的LED驱动电路,并评估其性能。

Our information is constantly under threat when transmitted through public networks. So, research to keep information secret has been carried out. Mainly, steganography, which consists of hiding data in digital media, receives much attention. Existing steganographic systems identified the need to improve performance by reducing a tradeoff between the peak signal-to-noise ratio (PSNR) and bits per pixel (BPP). In this paper, we propose a new steganographic scheme to embed the bits of secret messages in a digital image’s pixels. Our method expands the differences between the neighbouring pixels for secret data concealment. We group the pixels in blocks of size $1times 3$, and two of the three pixels of the block are candidates to hold the secret bit. We also propose extracting the hidden data to validate our data concealment scheme. To extract the secret data, we also arrange the neighbouring pixels into blocks of three and use their differences, and a modulus function, based on pixels identified carrying the secret data based on the key generated during data concealment. To evaluate the performance of our scheme, we consider the PSNR and the BPP as metrics. The experimental results showed better performance over the existing methods with 68.7790 dB for the PSNR and 0.1562 BPP.
我们的信息在通过公共网络传播时经常受到威胁。为此,开展了信息保密研究。隐写术是一种将数字媒体中的数据隐藏起来的技术,近年来受到越来越多的关注。现有的隐写系统需要通过减少峰值信噪比(PSNR)和每像素比特数(BPP)之间的权衡来提高性能。在本文中,我们提出了一种新的隐写方案,将秘密信息嵌入到数字图像的像素中。我们的方法扩展了相邻像素之间的差异,用于隐藏秘密数据。我们将像素分组在大小为$1 × 3$的块中,并且块的三个像素中的两个是保存秘密位的候选像素。我们还提出提取隐藏数据来验证我们的数据隐藏方案。为了提取秘密数据,我们还将相邻像素分成三个块,并利用它们之间的差异,以及基于数据隐藏过程中生成的密钥识别的携带秘密数据的像素的模函数。为了评估我们的方案的性能,我们考虑PSNR和BPP作为指标。实验结果表明,该方法的PSNR为68.7790 dB, BPP为0.1562,优于现有方法。

Around 38% of land in the world is used for agriculture and the whole world is completely dependent on agriculture. So, that’s why good crop yield is very important to get high agricultural output. A single disease in a plant can lower crop yield. So, to maintain a high agricultural output, we need to detect disease at the early stage so that the agricultural output should be maintained. There are multiple ways to detect plant disease like detecting a plant disease by using the naked eye by hiring an expert, or by using Artificial Intelligence (AI). By using AI, it takes less time to detect plant disease as compared to detecting using the naked eye. Deep Learning (DL), the sub-branch of AI gives an accurate result as compared to the other sub-branches of AI. In DL, Convolutional Neural Network or CovNet is the latest and revolutionary algorithm to perform this task. An apple tree disease detection model, based on Multilayer CNN, is presented in the paper.

世界上大约38%的土地用于农业,整个世界完全依赖农业。所以,这就是为什么好的作物产量对获得高农业产量非常重要。一种病害就能降低作物产量。因此,为了保持较高的农业产量,我们需要在早期发现疾病,这样才能保持农业产量。检测植物病害的方法有很多种,比如聘请专家用肉眼检测植物病害,或者使用人工智能(AI)。与肉眼检测相比,使用人工智能检测植物病害所需的时间更短。与人工智能的其他分支相比,人工智能的分支深度学习(DL)给出了准确的结果。在深度学习中,卷积神经网络或CovNet是执行这项任务的最新和革命性的算法。提出了一种基于多层CNN的苹果树病害检测模型。为了训练所提出的多层CNN模型,数据收集自Plant Pathology 2021的FGVC8数据集,该数据集是由“康奈尔数字农业倡议”(Cornell Initiative for Digital Agriculture)支持的Kaggle竞赛,决策树、逻辑回归和随机森林是与所提出模型的性能进行比较的机器学习算法。本研究表明,该模型的准确率为91%,精密度为89%,召回率为85%,F1-Score为88.34%,优于机器学习算法。

So, that’s why good crop yield is very important to get high agricultural output. A single disease in a plant can lower crop yield. So, to maintain a high agricultural output, we need to detect disease at the early stage so that the agricultural output should be maintained. There are multiple ways to detect plant disease like detecting a plant disease by using the naked eye by hiring an expert, or by using Artificial Intelligence (AI). By using AI, it takes less time to detect plant disease as compared to detecting using the naked eye. Deep Learning (DL), the sub-branch of AI gives an accurate result as compared to the other sub-branches of AI. In DL, Convolutional Neural Network or CovNet is the latest and revolutionary algorithm to perform this task.

Beidou technology is used to identify the position of a station and its position relative to other stations. Beidou system can be applied to the acceptance of overhead transmission lines, so that when the new lines are completed, we can judge whether there are any obstacles between them. In the process of infrastructure acceptance, new technologies should be applied to replace existing technologies. The application of Beidou technology in overhead transmission lines is a new technology developed in China, which can be used to replace the satellite communication system currently used for mobile communication. The application of Beidou technology in overhead transmission lines refers to the use of satellite positioning system (GPS) to locate underground power cables or other buried structures at a certain distance from overhead transmission lines. This method can be used to locate underground power cables or other buried structures at a certain distance from overhead transmission lines. The method is to use GPS signals transmitted by satellites orbiting around the equator of the earth at an altitude of about 2.
