The research article presents a learner friendly Recommendation System of an E-Learning framework which is based on (DEW) Cloud Computing and providing service in an effective and economic way for delivering educational/academic course to remote places of North-Eastern region of India. Generally, in regions where learners do not get much opportunity to use new technologies for effective and quality learning this system is a very useful and convenient tool. E-Learning (rather U-Learning) based recommendation system is discussed for less resourced community, i.e. North Eastern language community (e.g., Khasi or/and Kokborok) for learning English where the medium of instruction is in local/tribal languages or mother tongue supported by modules and instructor (a blended learning approach). A semi-supervised ELL (i.e., English language learning) course is recommended to the learner on the basis of learners” aptitude/caliber on English language. Recommendation system is based on Django framework encoded in python programming language. The ELL (English Language Learning) courses are designed for secondary section learners from North-Eastern states of India with features like, data analytics (for recommendation system), and descriptive language teaching methodology.

Real Time Automation on Real Estate using API 使用API的房地产实时自动化
M. S. Bennet Praba, Udith Rajeev, A. Rathore, Ankit Kolangarath
Real estate can be confusing, unclear, disoriented and many a times the price or listings are put up randomly what the seller decides. Such a system makes it difficult for buyers to make reliable decisions also for a seller to determine what price must he put up the listing or what their property is worth. There are various aspects that decide the price of a property - proximity to public transport, cities, neighborhood and cultural aspects, availability, furnish status, etc. A model has to be deployed to provide accurate real estate decisions that are based on a variety of features and tags related to the property. To estimate such a value real time, we need a real time data source to help a community or individual determine the actual deserving value for their property they wish to buy or sell. This system looks to deploy well designed models that can adjust to variations in data due to geographical, economic and political differences by modelling real time data using an API
房地产可能会让人困惑、不清楚、迷失方向,很多时候,价格或房源都是卖家随意决定的。这样的制度使得买家很难做出可靠的决定,也使得卖家很难确定他必须在清单上列出的价格或他们的房产的价值。决定一处房产价格的因素有很多——距离公共交通的远近、城市、社区和文化因素、可用性、装修状况等。必须部署一个模型,以基于与该属性相关的各种特征和标记提供准确的房地产决策。为了实时估计这样的价值,我们需要一个实时数据源来帮助社区或个人确定他们希望购买或出售的财产的实际价值。该系统旨在部署设计良好的模型,通过使用API对实时数据进行建模,从而适应地理、经济和政治差异造成的数据变化

Effective Negation Handling Approach for Sentiment Classification using synsets in the WordNet lexical database 基于WordNet词汇数据库句法集的情感分类有效否定处理方法
Utkarsh Lal, Priyanka Kamath
Good quality of data preprocessing will have a greater impact on improving the performance of the classification models. Negation is one of the most important features in textual data. Only one negation word can change the polarity of the whole sentence. It is often seen that words like ‘not’, ‘non’ or suffixes like “n't” are removed during noise removal thereby leading to blunders in Sentiment Classification. Effective Feature extraction is the cornerstone of effective Sentiment Analysis and Negation handling is simply essential for this purpose. In this paper, an effective function for handling negations based on First Sentiment Word (FSW) antonymy in the WordNet has been implemented on a set of IMDB movie reviews. The function for Negation Handling created for this paper increased the accuracy of Sentiment Classification by 4-8%. Experiments done in this paper show that improving the quality of the data gives higher results than implementing different state-of-the-art methods like n-grams and even deep learning methods like Word Embeddings, especially when used in an industry setting, where there is a need of quick deployments and changes with cost effectiveness and resource management.
良好的数据预处理质量对提高分类模型的性能有较大的影响。否定是文本数据最重要的特征之一。一个否定词就能改变整个句子的极性。在去噪过程中,经常会出现“not”、“non”或“n’t”等词缀被去掉的情况,从而导致情感分类出现错误。有效的特征提取是有效情感分析的基石,而否定处理是实现这一目的的必要条件。本文在一组IMDB电影评论上实现了基于WordNet中第一情感词反义词的否定处理功能。本文创建的否定处理函数使情感分类的准确率提高了4-8%。本文中所做的实验表明,提高数据质量比实施不同的最先进的方法(如n-grams)甚至深度学习方法(如Word Embeddings)获得更高的结果,特别是在需要快速部署和更改成本效益和资源管理的行业环境中使用时。

S. Salma, H. Khan, B. Madhav, V. V. Sai Varun, A. K. Priyatham, D. Sandeep
A multi-band, Multi-Input and Multi-Output (MIMO) antenna was transformed into an Ultra-Wide Band (UWB) MIMO antenna through a novel optimisation technique. In this study, the Particle swarm optimisation method was used to optimise the MIMO antennas physical parameters. Initially, the design-related aspects of the MIMO were considered as the optimisation parameters with a functional goal of achieving a UWB band. The particle swarm optimiser successfully optimised the geometrical parameters of the proposed MIMO. A MIMO prototype antenna was fabricated on the widely present, cost-effective FR-4 material to validate the optimised parameters. Anechoic chamber measurements were taken to verify the performance of the prototype MIMO antenna. In all the tested parameters, the measurement values are in a good pact with the software simulations. The requirements for a UWB are validated from the measurement results. So, the particle swarm optimiser successfully optimised the given task through achieving the UWB. The developed antenna is appropriate for many commercial and widely used frequency bands of the UWB, like 2.45 GHz of Wi-Fi, 3.5 of Wi-MAX and 5.8 GHz of ISM band.

Universities must have properly implemented and qualified laboratories for the comprehensive training of students. There are laboratories with laser cutters and 3D printers but very few with a robotic system that can be used by students. For this reason, the innovative research was carried out in 2021 under the supervision of the School of Mechatronics Engineering at Ricardo Palma University, it was creating a robotic system that allows soldering THT electronic components on printed circuit boards, to help students to perform this process. The robotic system will be able to adapt to different sizes of circuit boards in a specified workspace, defined by $23 text{cm}times 17 text{cm}$, and reach the farthest points of the circuit boards due to the 5 degrees of freedom that compose it. This study presents mechatronics conceptual design and kinematic analysis simulation of the structure, which is a set of a translation joint with reference to the cartesian robot movement and rotation joints that compose a manipulator. In addition, the end effector will be a soldering iron beside a pipe for the tin output which will be connected to a pair of gears controlled by a stepper motor to dispense the filler material. The robot is pretended to be applied to laboratories of Ricardo Palma University. In conclusion, favorable results were achieved; consequently, the next step of the project is to apply a camera for the solder path recognition and expand its use for SMD electronic components.
大学必须有适当实施和合格的实验室,以全面培养学生。有些实验室有激光切割机和3D打印机,但很少有可以供学生使用的机器人系统。出于这个原因,这项创新研究于2021年在里卡多帕尔马大学机电工程学院的监督下进行,它正在创建一个机器人系统,可以在印刷电路板上焊接THT电子元件,以帮助学生完成这一过程。机器人系统将能够在指定的工作空间中适应不同尺寸的电路板,该工作空间由$23 text{cm}乘以$ 17 text{cm}$定义,并且由于构成它的5个自由度而到达电路板的最远点。本文对该结构进行了机电一体化概念设计和运动学分析仿真,该结构是一组平移关节,参照笛卡尔机器人的运动关节和旋转关节组成一个机械手。此外,末端执行器将是锡输出管道旁边的烙铁,锡输出管道将连接到由步进电机控制的一对齿轮上,以分配填充材料。该机器人被认为应用于里卡多帕尔马大学的实验室。总之,取得了良好的效果;因此,该项目的下一步是应用相机进行焊料路径识别,并扩大其在SMD电子元件中的应用。

Design of a Novel Discrete Command Generation and Distribution Scheme for Spacecrafts 一种新的航天器离散指令生成与分配方案设计
Aashish Kumar, B. Varaprasad, J. Kishore
Spacecraft telecommand system plays a critical role in receiving commands from ground station and distributing them to various subsystems. Command Execution Units (CEUs) and Command Distribution Units (CDUs) are the critical building blocks of a spacecraft telecommand system that perform the major functions of generation and distribution of discrete commands (pulse, level and serial data). The number of discrete commands required to support operation of subsystems varies from spacecraft to spacecraft and hence has impact on the design of hardware modules used in the telecommand system. In this article, a novel scheme for generation and distribution of discrete commands is presented that provides the feature of reprogramming the command outputs for supporting different types of discrete commands. This feature helps in minimizing the types of Very Large Scale Integration (VLSI) devices and number of hardware modules used in generation and distribution of discrete commands. It also supports the development of reusable hardware designs for use across different spacecraft missions and aids in reducing the turn around time for realization of mission specific telecommand hardware. At the core of the scheme is the design of a VLSI device with reconfigurable outputs that support the four basic discrete command interfaces - pulse, level, serial data and switch matrix. Suitable mitigation techniques have been incorporated in the design for overcoming single event upsets caused due to space radiation. This design has been realized as an Application Specific Integrated Circuit (ASIC) and planned to be used in the development of reconfigurable hardware module for CDU.
航天器遥控系统在接收地面站的指令并将其分发到各个子系统中起着至关重要的作用。指挥执行单元(ceu)和指挥分配单元(cdu)是航天器远程指挥系统的关键组成部分,它们执行离散命令(脉冲、电平和串行数据)的生成和分配的主要功能。支持子系统操作所需的离散命令数量因航天器而异,因此对远程指挥系统中使用的硬件模块的设计有影响。本文提出了一种新的离散命令生成和分布方案,该方案提供了命令输出的重新编程功能,以支持不同类型的离散命令。此功能有助于最大限度地减少超大型集成(VLSI)设备的类型和用于生成和分发离散命令的硬件模块的数量。它还支持开发可重复使用的硬件设计,以便在不同航天器任务中使用,并有助于减少实现特定任务的电信指挥硬件的周转时间。该方案的核心是设计一个具有可重构输出的VLSI器件,该器件支持四个基本的离散命令接口——脉冲、电平、串行数据和开关矩阵。在设计中采用了适当的减缓技术,以克服空间辐射引起的单一事件扰动。该设计已作为专用集成电路(ASIC)实现,并计划用于CDU可重构硬件模块的开发。

LOW Complexity Segmentation With a Hybrid Subblock In MIMO OFDM Systems, The PTS Scheme For PAPR Reduction MIMO OFDM系统中混合子块的低复杂度分割,PTS方案降低PAPR
T. Naidu, M. V. Narayana, G. Immadi, Sai Karthik Gamineedi, Arun Chowdary Nukavarapu, P. P. Kumar
MIMO-OFDM stands for multiple-input and multiple-output orthogonal frequency division multiplexing is utilized to support the presentation and ability of a remote correspondence framework. OFDM is an Associate in Nursing affordable and promising adjustment procedure for remote transmission due to its high phantom strength and toughness to recurrence-specific weakening channels. Nonetheless, the main disadvantage might be the high peak average to power ratio (PAPR). Partial Transmit Sequence (PTS) is one of the chief wide utilized procedures for MIMO-OFDM frameworks, this results in substantially improved PAPR reduction execution. The method nature of the archaic PTS approach, on the other hand, is massive. In a MIMO-OFDM system, a low-complexity hybrid subblock segmentation PTS topic for PAPR reduction has been developed and planned to be presented in this study.

MIMO-OFDM即多输入多输出正交频分复用,用于支持远程通信框架的表示和能力。OFDM是一种可负担且有前途的远程传输调节方法,因为它具有高的模体强度和对复发特异性减弱通道的韧性。尽管如此,主要的缺点可能是峰值平均功率比(PAPR)很高。部分传输序列(PTS)是MIMO-OFDM框架中广泛使用的主要程序之一,这大大提高了PAPR降低的执行。另一方面,古老的PTS方法的方法本质是大量的。在MIMO-OFDM系统中,一个用于降低PAPR的低复杂度混合子块分割PTS主题已经被开发并计划在本研究中提出。对于有洞察力的能力,我们通常会推断计划划分哲学的系统质量表述,并剖析计划划分方法的技术性质,立即分析不规则划分策略,该策略在峰值与平均功率比(PAPR)减少执行之间具有最直接的定量关系。仿真结果表明,PAPR减小执行过程中出现了排异和不规则分割。

Diabetic Retinopathy Detection Using Deep Learning Methods 利用深度学习方法检测糖尿病视网膜病变
S. Suganyadevi, K. Renukadevi, K. Balasamy, P. Jeevitha
Diabetes mellitus causes diabetic retinopathy (DR), which is the primary source of blindness worldwide. Initial identification and cure are required to postpone or avert visual degradation and loss. In this regard, various artificial-intelligence-powered approaches for detecting and classifying diabetic retinopathy on fundus retina pictures have been proposed by the scientific community. This paper will mostly examine existing early DR diagnostic tools to determine their merits and drawbacks. Although pictures from fluorescein angiography, colour fundus medical images or visual lucidity tomography angiography are used for early diagnosis. Only colour fundus medical images are included in this study. It is possible to categorise the early DR detection methods described in this paper as either classical image processing, traditional machine learning, or deep learning. The issues that must be addressed in creating such efficient, effective and resilient methods for initial detection of DR systems are discussed in length in this study, as is the substantial opportunity for future research in this field.

Configurable Drive Scheme for Stepper Motors in Space Application 空间应用中步进电机的可配置驱动方案
V. Lekshmi, B. Varaprasad, G. Navle Sonal, T.S. Vishnu
Motors are employed in satellites for various operations. Control drives for these motors are achieved with custom designs, which are specific to the application, motors used, load to be driven and the drive schemes chosen. Instead of using a custom specific design, a common platform for drive electronics will help to circumvent development hassles and shorten the realisation time. This article discusses the requirements/applications of stepper motors in a spacecraft and a configurable architecture as a standard design for the open loop drive of stepper motors. A Field Programmable Gate Array (FPGA) based digital controller is designed to provide all the configurable features, through programmability and tele-command. To ensure a fail-safe system, safety logics are built-in to the controller and health monitoring is provided through a telemetry interface. Also, usage of space grade FPGAs and other qualified parts ensure a reliable system architecture for a radiation hardened environment. The proposed drive scheme accomplishes the need for a configurable and reliable design, best suited for motor drive electronics, for the open loop drive of stepper motors in a spacecraft.
