Ultra-Wide Band (UWB) radio communication plays a major role and widely applied for low data level applications like networks sensor and delivers data rates which are high for short-term communications. However, the enormous ratio of fading channel solvable paths confounds the layout of the receiver. To solve these issues (timing and channel estimation), channel communication, transmitted reference (TR) UWB systems were used. Still, the implementation of the TR-UWB systems faces problems as difficulty building in an integrated circuit with low power and mysterious delay dimension. To overcome these issues, the study presents a Frequency-Shifted Reference (FSR) UWB system toward estimating the timing error and control the timing pulse. Specifically, a tracking loop based on particle filtering with the acquisition method in FSR-UWB system with multipath channel conditions has been considered. The particles are discrete and signals are having distributed samples that grow over time. From the simulation results, it is seen that a higher tracking precision and wider timing range is obtained with digital timing loop.
超宽带(UWB)无线电通信在网络传感器等低数据级应用中发挥着重要作用,并广泛应用于短期通信的高数据速率。然而,巨大的衰落信道可解路径比例干扰了接收机的布局。为了解决这些问题(时序和信道估计),使用了信道通信,传输参考(TR) UWB系统。然而,TR-UWB系统的实现面临着难以在低功耗集成电路中构建和延迟维度神秘的问题。为了克服这些问题,研究提出了一种移频参考(FSR)超宽带系统,用于估计定时误差和控制定时脉冲。具体来说,研究了多径信道条件下FSR-UWB系统中基于粒子滤波的跟踪环路。粒子是离散的,信号具有随时间增长的分布样本。仿真结果表明,采用数字定时环可以获得更高的跟踪精度和更宽的定时范围。

Cloud computing is a vast platform which provides users with ample services. It offers various benefits such as expense reduction, resource elasticity, managing data and easier services for hosting. At the same time, the aspects such as security, performance and reliability are the key concerns in cloud paradigm. Therefore, trustworthiness in adopting a cloud service becomes an important issue from the end user's viewpoint. Trust represents the degree to which user's expectations about the capabilities of a service are met. This paper proposes trust evaluation and cloud service recommendation system (TECSRS) which concentrates on evaluation of trust using Quality of Service (QoS) parameters. TECSRS uses Machine Learning techniques which include Linear Regression, Artificial Neural Networks (ANN), Random Forest Regression and Support Vector Regression (SVR), in trust computation. TECSRS facilitates recommending a cloud service to the end user and forecasting the trust values of cloud services. Experimental results depict that the Random Forest Regression model outperforms the other machine learning models with regard to accuracy of trust computation.

Lip reading is an approach for understanding speech by visually interpreting lip movements. Vision based lip leading system takes a video (without audio) as an input of a person speaking some word or phrase and provides the predicted word or phrase the person is speaking as output. This paper presents the method for Vision based Lip Reading system that uses convolutional neural network (CNN) with attention-based Long Short-Term Memory (LSTM). The dataset includes video clips pronouncing single digits. The pretrained CNN is used for extracting features from pre-processed video frames which then are processed for learning temporal characteristics by LSTM. The SoftMax layer of architecture provides the result of lip reading. In the present work experiments are performed with two pre-trained models namely VGG19 and ResNet50 and the results are compared. To further improve the performance of the system ensembled learning is also used. The system provides 85% accuracy using ResNet50 and ensemble learning.
唇读是一种通过视觉解读唇动来理解言语的方法。基于视觉的唇导系统将视频(没有音频)作为一个人说某个单词或短语的输入,并提供该人正在说的预测单词或短语作为输出。本文提出了一种基于卷积神经网络(CNN)和基于注意的长短期记忆(LSTM)的基于视觉的唇读系统的方法。该数据集包括发音为个位数的视频片段。使用预训练好的CNN从预处理的视频帧中提取特征,然后通过LSTM对这些特征进行处理,学习时间特征。SoftMax架构层提供唇读结果。本文采用VGG19和ResNet50两种预训练模型进行了实验,并对实验结果进行了比较。为了进一步提高系统的性能,还采用了集成学习的方法。系统使用ResNet50和集成学习提供85%的准确率。

The most prevalent form of authentication or computer system intrusion protection is the use of alphanumeric usernames and passwords. Strong password schemes have traditionally provided a certain level of protection, but they are complicated and difficult to remember, prompting their owners to write them down on paper. As a consequence, protection is jeopardized.Increasing the sharing of information, internet use, data transfer, protection and validation of passwords have become significant challenges.As a result, many programmes use different hashing and salting algorithms to store password files in databases.Attackers, on the other hand, do not consider password hashing to be safe since they use brute force attacks, password guessing attacks, and other methods to obtain the user's password from the database's password log.Some systems store passwords in databases using honeywords or bogus passwords generated using the generation technique for honeywords to prevent hacker attacks.In our recommended approach, passwords are saved using a distinct hashing mechanism with a less complexity of time in which majority of the processes need basic operation based on binarys.
最普遍的身份验证或计算机系统入侵保护形式是使用字母数字用户名和密码。传统上,强大的密码方案提供了一定程度的保护,但它们很复杂,很难记住,这促使它们的主人把它们写在纸上。因此,保护受到了损害。增加信息共享、互联网使用、数据传输、密码保护和验证已成为重大挑战。因此,许多程序使用不同的散列和腌制算法在数据库中存储密码文件。另一方面,攻击者不认为密码哈希是安全的,因为他们使用暴力攻击、猜密码攻击和其他方法从数据库的密码日志中获取用户的密码。为了防止黑客的攻击,一些系统使用honeyword或利用honeyword生成技术生成的伪密码存储在数据库中。在我们推荐的方法中,使用不同的散列机制保存密码,时间复杂度较低,其中大多数进程需要基于二进制的基本操作。

Devanagari language comprises 47 primary characters that include 14 vowels and 33 consonants. Nearly 120 scripts have been developed from it like Marathi, Hindi, Bengali, etc. This paper deals with a Marathi handwritten word recognition system. Marathi is an Indian language that is spoken primarily in the state of Maharashtra, most of the government paperwork is done in this language only. This system will mainly be used in recognizing various handwritten words present in the titles of different municipal documents. The main concern regarding these documents was the task of storing them digitally. The existing works have used the method of segmentation and have proposed a hidden Markov model to recognize pseudo characters, but the accuracy can be increased. We have devised a system that will overcome this limitation. In our system, a dataset is created for 2000 samples and by applying different augmentation techniques the dataset size is further increased to 12000 images. The proposed system is implemented using deep learning based Customized Convolution Neural Network which is pre-trained on a manually collected dataset containing various Marathi handwritten words. Out of which 75% of the dataset is used for training and 25% for testing purposes. This system has proved better results on augmented data with 94% accuracy.
梵语由47个主要字符组成,其中包括14个元音和33个辅音。从它发展出了近120个脚本,如马拉地语、印地语、孟加拉语等。本文研究了一个马拉地语手写单词识别系统。马拉地语是一种印度语言,主要在马哈拉施特拉邦使用,大多数政府文书工作都是用这种语言完成的。该系统将主要用于识别不同市政文件标题中出现的各种手写文字。对这些文档的主要关注是数字化存储它们的任务。现有的工作都是使用分割的方法,并提出了一种隐马尔可夫模型来识别伪字符,但精度还有待提高。我们已经设计了一个系统来克服这个限制。在我们的系统中,为2000个样本创建了一个数据集,通过应用不同的增强技术,数据集的大小进一步增加到12000个图像。该系统使用基于深度学习的自定义卷积神经网络实现,该神经网络在手动收集的包含各种马拉地语手写单词的数据集上进行预训练。其中75%的数据集用于训练,25%用于测试。该系统在增强数据上取得了较好的效果,准确率达到94%。

Automatic Identification System (AIS), the automated data collection system for vessel tracking, plays an essential role in marine traffic management. AIS system is generating an enormous volume of data which has rampant growth. The AIS data has the potential to drive transport activities, and significant hidden insights are possible to draw by analyzing the AIS data. Some of the tasks which can rely on the AIS data are predicting routes of vessels, predicting traffic intensity, estimating the time of arrival of a ship and transport of volume.

The NDVI is an extensively used numerical indicator that utilizes the NIR and red band of the EM spectrum. It is waged to analyse and evaluate the ground locations for the presence of live green vegetation by using remote sensing images. This paper provides an analysis of the utility of NDVI in mapping the wheat crop of selected area of Saharanpur region, Uttar Pradesh, India. Images of Sentinel 2B were collected from November 16, 2018 to April 15, 2019. A total of 16 different date satellite images were analysed to calculate NDVI values of same region. For land cover classification various indices are used. Vegetation, sparse vegetation and dense vegetation can be identified by computing NDVI. In this article 16 different sentinel images of Saharanpur region are processed to identify the wheat crop on the basis of NDVI values. the graph shows high NDVI values in the month of march.
