A New Assistive Technology in Android Platform to Aid Vocabulary Knowledge Acquirement in Indian Sign Language for Better Reading Comprehension in L2 and Mathematical Ability Android平台辅助印度手语词汇知识获取的新技术,提高二语阅读理解和数学能力
Sandipa Roy, A. Maiti, Indira Ghosh, I. Chatterjee, Kuntal Ghosh
A new app on android platform has been proposed and designed to help speech and hearing impaired persons to develop vocabulary knowledge in breadth as well as depth in Indian Sign Language (ISL) through the learning of relevant synonyms and antonyms and mapped into semantic connotation via sign inputs to recognize the symbols in absence of sound through some visual clues (Sign Video). The vocabulary acquirement scheme in ISL is chosen in such a way that the understanding capability and logical sense in the second language (L2) will grow automatically. Finally, the android app in different regional languages (English with ten regional languages) used in India has been implemented, thus introducing a mobile App based Indian Sign Language Dictionary with synonyms, antonyms, presently in Bengali, along with different sentence making examples. This app is so aimed that the intellectual ability, writing skill and mathematical ability of the speech and hearing impaired can flourish in tandem with learning of normal students.
本文提出并设计了一款基于android平台的新应用,通过学习相关的同义词和反义词,帮助言语和听力障碍人士拓展印度手语词汇知识的广度和深度,并通过符号输入映射到语义内涵,通过一些视觉线索在没有声音的情况下识别符号(Sign Video)。ISL词汇习得方案的选择是为了使第二语言的理解能力和逻辑意识自动增长。最后,在印度使用的不同地区语言(英语和十种地区语言)的安卓应用程序已经实现,从而引入了一个基于移动应用程序的印度手语词典,其中包含同义词,反义词,目前在孟加拉语中,以及不同的造句示例。这款应用的目的是让语言和听力受损的人的智力、写作技能和数学能力与正常学生的学习同步发展。

Analysis of Dielectric Rods Supported Anistropically Conducting Rectangular Helix Slow Wave Structure 介质棒支撑的各向异性导电矩形螺旋慢波结构分析
Snehitha Kodali, Shreya Mohta, Tejas Munees, Naveen G. Babu
The dispersion equation of a dielectric loaded anisotropically conducting tape helix slow wave structure for planar TWTs is derived. By assuming the current density behavior on the rectangular tape helix, the dispersion relation is obtained through accurate boundary conditions that restrict the field only on the tape surface and not in the gap regions. Substitution of the field equations in the boundary conditions results in the six complex constants of the field equations. The complex constants are re-substituted in the last boundary condition that consists of the restricting function or the indicator function to arrive at the dispersion equation. The derived dispersion equation can be used to obtain the dispersion characteristics for a more practically relevant planar TWT interaction structure.

Ajay Kumar Keshari, R. Ramakrishnan, J. P. Rao, V. Jayaraman, A. S. Rama Murthy
The multichannel data acquisition system is developed for the measurement of the resistance of metal oxide sensor array response for electronic nose application. The resistance of the sensor varies with the concentration of analytes. The instrumentation is developed in-house which measures the output of sensor array and sends the data to the PC through LAN. The data acquisition software was developed for four channels to collect the data in PC in the form of counts and converts it into the resistance of sensors by using a suitable algebraic equation. Principal Component Analysis was implemented in the software to discriminate the analytes. The software is equipped with user-friendly features like online monitoring, on-demand pop-up window to check the overall trend of sensor behavior for a larger data etc. The data are stored with the time stamp in a file for post analysis. The data acquisition software was tested with various standard resistors and found the results were good. Further, the data acquisition software was also tested with the sensor and logged the sensor data for the study of sensors. The features of this development and the results obtained from the experiments are described in this paper.

Design of Low Power ECRL Based Power Gated 4:2 Compressor 基于ECRL的低功耗功率门控4:2压缩机设计
Naman Malhotra, A. Mann, N. Pandey
Advent of new age technologies like augmented reality (AR) has made techniques like digital signal processing (DSP), image and speech processing one of the most frequently used and important techniques. Multipliers are the fundamental components of these techniques which depend on extensive multiplications and numerical manipulations. Compressors are a crucial and important unit of multipliers that largely influence the speed and power dissipation of multipliers. This paper proposes a low power ECRL based 4:2 compressors by employing power gating. Two different power gating methodologies have been evaluated and compared, at varying load capacitances, supply voltage and frequency of the power clock signal, using 32nm PTM CMOS technology parameters. The small overhead observed in active state power dissipations is well compensated for by the significant power savings in idle states.

Performance Analysis of Compression Techniques Using LM Algorithm and SVD for Medical Images 基于LM算法和SVD的医学图像压缩技术性能分析
M. Rani, G. Rao, B. Rao
This paper presents the techniques for compression and decompression of MRI, CT and X-ray images. These medical images are the pictorial representation of inner parts of human body which are used for the analysis of critical diseases. As the vast amount of data is required to store medical images for future reference of the patients and for the transmission, there is need to use image compression methods without reducing the quality of information. Two methods of compression i.e. back propagation neural network with LM training algorithm (BPNNLM) and Singular Value Decomposition (SVD) are used in this paper. The results of these two techniques are compared with respect to the performance metrics of Peak Signal to Noise Ratio (PSNR), Mean Squared Error and Structural Similarity Index Measurement (SSIM). From the results, it is observed that SVD image compression technique based on singular values provides more PSNR, less MSE and better SSIM values compared to BPNNLM Technique.

As the vast amount of data is required to store medical images for future reference of the patients and for the transmission, there is need to use image compression methods without reducing the quality of information. Two methods of compression i.e. back propagation neural network with LM training algorithm (BPNNLM) and Singular Value Decomposition (SVD) are used in this paper. The results of these two techniques are compared with respect to the performance metrics of Peak Signal to Noise Ratio (PSNR), Mean Squared Error and Structural Similarity Index Measurement (SSIM). From the results, it is observed that SVD image compression technique based on singular values provides more PSNR, less MSE and better SSIM values compared to BPNNLM Technique.","PeriodicalId":344030,"journal":{"name":"2019 6th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121757100","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}
