With the growth of world communication, wireless communication has become one of the most prominent sectors. The design and simulation result of the 24 GHz (ISM band) antenna has been developed in this article. Many publications have addressed this research and developed antennas utilizing arrays. However, the proposed design provides a novel model of a small size patch antenna that is easier to build and has improved return loss, efficiency, and gain than previous research studies. The recommended patch antenna design is 18mm×2.451mm×0.257mm. The substrate material for this antenna is Roger RT5880 (lossy), which has a permittivity of 2.2. According to the simulation results, this design has a return loss of -28.96 dB, a VSWR (Voltage Standing Wave Ratio) of 1.08497, a gain of 5.152 dB, and an antenna efficiency of 67.026%. The patch antenna is expected to function effectively and may be used for wireless communication based on simulation results.

This paper examines the theoretical basis for the elaboration of a development strategy for an organization producing household appliances, especially refrigeration equipment. We considered what the strategic management is and what it solves. And also studied the basic principles of strategic management. It has been found that there are two approaches to strategic management that differ in how organizations use their resources. Moreover, during the course of the work, issues related of development the strategic management of the organization were identified. It was found that it is economically beneficial for both the supplier and consumers to carry out domestic assembly of foreign equipment, as this allows manufacturers to significantly reduce customs duties and transportation costs. Thus, in order to develop an organization's development strategy, it is necessary to separate the tools to develop a strategy depending on the place of origin. It has proved necessary to apply a scientific and methodological approach, to identify and analyse the gaps and to develop patterns for selecting strategic alternatives.
本文考察了一个生产家用电器,特别是制冷设备的组织制定发展战略的理论基础。我们考虑了战略管理是什么以及它解决了什么问题。并研究了战略管理的基本原理。已经发现,在组织如何使用资源方面,有两种不同的战略管理方法。此外,在工作过程中,还确定了与发展和本组织战略管理有关的问题。研究发现,对供应商和消费者来说,将外国设备在国内组装在一起在经济上都是有利的,因为这使制造商可以大大降低关税和运输成本。因此,为了开发一个组织的开发战略,有必要根据起源的地方分离开发战略的工具。事实证明,必须采用科学和方法的办法,查明和分析差距,并制订选择战略备选办法的模式。

The paper complied and structured data to construct a correlation model. The reasons for flight delays and cancellations between 2009 from 2019 are examined, based on the statistical electronic source "Bureau of Transportation Statistics". The normalized data are calculated from the primary data. Based on the data collected, a primary histogram was constructed (outliers were not checked). In addition, significant and weak influencing factors have been identified for the constructing of a correlation table, this table helps to identify an additional factor influencing a flight delay or cancellation. Based on the data from the table, a new histogram was built and a correlation table was constructed, allowing regression analysis to be started. At the beginning of the regression analysis, regression statistics are used and an analysis of variance is performed, then the regression analysis is performed directly and the results of the regression are summed up. Based on the summed-up results, a histogram was built, which takes into account all the statistics and calculations, showing the predicted number of delays or cancellations of flights and their actual number.

This paper investigates the system sizing, schema, modeling, and simulation of a 500 MW, grid-connected PV farm at a site close to the Churchill Falls Airport in Labrador. The objective is to understand the PV farm’s technical and economic feasibility. The system is sized manually and with the help of PVWatts. The outputs from this calculation and PVWatts are used to select system components, such as solar panels and MPPT inverters. The plant is divided into four blocks of 125 MW each for ease of maintenance, control, and redundancy for planned and unplanned outages. Pooling transformers, high voltage switchgear, grid transformers, and the export transmission line are sized accordingly. System performance is analyzed using NREL’s System Advisor Model (SAM) software. The grid-connected PV system, with the inverter, is modeled in Simulink (MATLAB) for dynamic simulations. Protection and control scenarios are also modeled in Simulink. The system’s output parameters are then analyzed to understand power output and stability. Finally, recommendations on feasibility and further work are discussed.

The heart is one of the crucial parts of the human being. The graphical recording of the cardiac cycle produced by an Electrocardiograph is called an Electrocardiogram (ECG) signal. To predict the occurrence of an arrhythmia, an electrocardiogram (ECG) is generally used by doctors to identify the condition of the patient. Hence, to accurately detect the abnormalities of the heart in advance and classify those diseases without human involvement many machine learning algorithms are used. The MIT-BIH Arrhythmia database is being used to classify the beat classification performance. This paper presents the hardware implementation of a classifier using an Artificial Neural Network (ANN) to classify four abnormalities (Normal beat, Supraventricular ectopic beat, Ventricular ectopic beat, Fusion beat) of heartbeat with high accuracy. To an appropriate input vector for the classifier, several preprocessing stages have been applied. Discrete Wavelet Transform (DWT) is used to extract the features from the ECG signal. To implement this work, Xilinx Artix-7 NESYS 4 DDR FPGA board is used. This model got 86% testing accuracy in simulation and 85.6% in hardware.
心脏是人类最重要的部分之一。由心电图仪产生的心电周期的图形记录称为心电图信号。为了预测心律失常的发生,医生通常使用心电图(ECG)来确定患者的状况。因此,为了提前准确检测心脏异常并在没有人类参与的情况下对这些疾病进行分类,使用了许多机器学习算法。MIT-BIH心律失常数据库被用于对心跳分类性能进行分类。本文介绍了一种基于人工神经网络(ANN)的分类器的硬件实现,该分类器对心跳的四种异常(正常心跳、室上异位心跳、室外异位心跳、融合心跳)进行了高精度的分类。为了得到一个合适的分类器输入向量,应用了几个预处理阶段。采用离散小波变换(DWT)对心电信号进行特征提取。为了实现这项工作,使用了Xilinx Artix-7 NESYS 4 DDR FPGA板。该模型的仿真测试精度为86%,硬件测试精度为85.6%。

In power system analysis, sometimes the combined influence of a part of the network is desirable/investigated instead of the dynamics of the individual components therein. For such studies, aggregated models of system components would become beneficial when obtaining the equivalent circuits for the subject part of the network. This paper presents an aggregation method for modeling a cluster of synchronous generators (SGs) connected to a common bus in a power grid. First, it is shown how the so-called transfer matrices can be used for equivalent dynamic modeling of the system components, e.g., SGs with field and damper windings. Then, the transfer matrix-based models of SGs are aggregated to obtain an equivalent dynamic model for the cluster of SGs. The proposed aggregated model of SGs is then validated compared to their full-order qd models using computer simulations. It is verified that the proposed aggregation technique can preserve the dynamic behavior of parallel SGs very accurately for low- and high-frequency electromagnetic oscillations while being computationally more efficient than their classical full-order qd model counterparts.
在电力系统分析中,有时需要研究一部分网络的综合影响,而不是其中单个组件的动态。对于这类研究,在获得网络主体部分的等效电路时,系统组件的聚合模型将是有益的。本文提出了一种同步发电机群(sg)的聚合建模方法。首先,它展示了如何将所谓的传递矩阵用于系统组件的等效动态建模,例如,具有场和阻尼器绕组的SGs。然后,对基于转移矩阵的聚类模型进行聚合,得到聚类的等效动态模型。然后用计算机模拟与他们的全阶量子点模型进行了比较,验证了所提出的聚合模型。结果表明,所提出的聚合技术在低频率和高频电磁振荡条件下能够很好地保持平行量子点的动态特性,同时计算效率也比传统的全阶量子点模型高。

SQL ChatBot – using Context Free Grammar SQL聊天机器人-使用上下文自由语法

In this work, we derive the semantics of a given English query and convert it into its equivalent SQL query. Instead of using neural networks for semantic analysis of English queries, we opt for a Context Free Grammar approach. Most neural-network-based systems can handle only one semantic at a time, whereas, because of the flexibility offered by our CFG approach, our system manages to handle simultaneous usage of conjunctive, disjunctive, and negative semantics. It also handles complex statements comprising of main as well as dependent clauses. In addition, the system also takes into account aggregate functions and constructs the required GROUP-BY and HAVING clauses. We describe how the system analyzes English queries by understanding the role that each part-of-speech has to play in constructing SQL queries. Numerous examples demonstrate the effectiveness of our approach where state-of-the-art techniques relying on deep learning algorithms fail to deliver.
在这项工作中,我们推导了给定英语查询的语义,并将其转换为等效的SQL查询。我们没有使用神经网络对英语查询进行语义分析,而是选择了上下文无关语法方法。大多数基于神经网络的系统一次只能处理一个语义,然而,由于我们的CFG方法提供的灵活性,我们的系统能够同时处理连接、析取和否定语义的使用。它还处理由主子句和从属子句组成的复杂语句。此外,系统还考虑了聚合函数,构造了所需的GROUP-BY和HAVING子句。我们描述了系统如何通过理解每个词性在构造SQL查询中所扮演的角色来分析英语查询。许多例子证明了我们的方法的有效性,而依赖于深度学习算法的最先进技术无法提供。

It also handles complex statements comprising of main as well as dependent clauses. In addition, the system also takes into account aggregate functions and constructs the required GROUP-BY and HAVING clauses. We describe how the system analyzes English queries by understanding the role that each part-of-speech has to play in constructing SQL queries. Numerous examples demonstrate the effectiveness of our approach where state-of-the-art techniques relying on deep learning algorithms fail to deliver.","PeriodicalId":442879,"journal":{"name":"2022 IEEE International IOT, Electronics and Mechatronics Conference (IEMTRONICS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129695336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a finite-time consensus for a connected network of heterogeneous unmanned aerial vehicles subjected to wind disturbances. A sliding mode control and graph algebraic theory based strategy is developed for consensus while independent tracking controller ensures robust trajectory following of an agent. Stability of the agents are decoupled from distributed consensus algorithm. Finite time convergence of the measurement vectors of heterogeneous agents to the agreement value are proved. Comparison results with the recent work show the superior performance of the proposed algorithm.

To maximize efficiency, quality of products, and profits, it is important to maintain machine tools to reduce downtime and maximize output. Predictive maintenance is the most efficient method of condition monitoring and maintenance. An Internet of Things approach can help implement an autonomous predictive CM system in manufacturing facilities. The critical parameters of sensor selection, communication, and data analysis have been examined. The components that make up an effective IoT CM system have been discussed and analyzed. An IoT approach has been shown to eliminate the disadvantages of traditional manual CM approaches.
