Energy Efficient CNTFET based Dual Mode Logic (C-DML) Design 基于节能CNTFET的双模逻辑(C-DML)设计
Neetika Yadav, N. Pandey, Deva Nand
To incorporate the benefits of both Carbon Nano Tube Field Effect Transistor (CNTFET) transistor technology and footed Dual Mode Logic (DML) style, this contribution introduces an energy efficient CNTFET based Dual Mode Logic style and is referred to as C-DML. Owing to continuous transistor scaling, MOSFET based DML design suffers large parametric variations, short channel effects, high heat dissipation and decreased gate control. To resolve these issues, the C-DML design is proposed and simulated for 2-input NAND, NOR and 2:1 multiplexer circuit using HSPICE tool with 32nm CNTFET Stanford model at 0.9V and 5fF load capacitance in static and dynamic mode for both footed type A and type B configuration. Power, delay, and PDP are used to compare the existing CMOS and proposed C-DML circuits. The proposed design offers a maximum PDP reduction of 92.66% in static mode and 79.08% in dynamic mode. The effect of temperature and voltage variations on the PDP of both CMOS and proposed CNTFET DML based 2:1 multiplexer is also investigated. It is observed that there is negligible effect of temperature on the performance of proposed C-DML based 2:1 multiplexer. A PDP reduction of 77.89%-83.82% in static mode and 82.07%-87.73% in dynamic mode is observed at different voltages. The proposed technique is capable of reducing PDP at all voltages and temperatures.
为了结合碳纳米管场效应晶体管(CNTFET)晶体管技术和足部双模逻辑(DML)风格的优点,本贡献引入了一种节能的基于CNTFET的双模逻辑风格,称为C-DML。由于晶体管持续缩放,基于MOSFET的DML设计面临参数变化大、通道效应短、高散热和栅极控制减少的问题。为了解决这些问题,本文提出了2输入NAND、NOR和2:1多路复用电路的C-DML设计,并利用HSPICE工具在静态和动态模式下,采用32nm CNTFET Stanford模型在0.9V和5fF负载电容下进行了仿真。功率、延迟和PDP被用来比较现有的CMOS和提议的C-DML电路。该设计在静态模式下提供92.66%的最大PDP降低,在动态模式下提供79.08%的最大PDP降低。研究了温度和电压变化对CMOS和基于CNTFET DML的2:1多路复用器PDP的影响。结果表明,温度对基于C-DML的2:1多路复用器性能的影响可以忽略不计。在不同电压下,静态模式下PDP降低77.89% ~ 83.82%,动态模式下PDP降低82.07% ~ 87.73%。所提出的技术能够在所有电压和温度下降低PDP。

Design and Analysis of Slot Loaded Microstrip Antenna for Breast Cancer Detection 用于乳腺癌检测的槽载微带天线设计与分析
Deepthy G S, Nesasudha M
Microwave breast imaging (MBI) promises a more accurate and safer modality for breast cancer detection to provide information about breast tissues that uses longer wavelength low power signals when compared to other conventional techniques like X-ray mammography. This paper includes the performance analysis of slot loaded microstrip patch antennas suitable for breast cancer detection. Four types of antennas structures: without any slits, with truncated corners, with L shaped slots and square shaped slits arranged serially are designed with the help of FR4(dielectric constant = 4.4) as the substrate which is simulated using CST software. The designed antenna has been compared with conventional ones and results shows the superiority of designed antenna in terms of S11parameter, gain, directivity, return loss. The gain of the designed antenna is far superior to that of conventional antennas. As such antennas are used extensively for medical applications the measure of specific absorption rate (SAR) becomes very critical. It has been observed in the different structures that insertion of slits, slots and truncations helps to vary the resonant frequency of the antenna and helps in achieving circular polarization which is needed for medical applications. Optimum performance is achieved using the designed antenna in terms of gain, VSWR, return loss and the radiation limits were obtained which falls within limit of 1.6 W/kg as recommended by FCC.
微波乳房成像(MBI)是一种更准确、更安全的乳腺癌检测方式,与x射线等其他传统技术相比,它使用更长的波长低功率信号来提供有关乳腺组织的信息。本文对适用于乳腺癌检测的槽载微带贴片天线进行了性能分析。利用介电常数为4.4的FR4作为衬底,利用CST软件进行仿真,设计了无缝隙、截角、L型缝隙和方形缝隙依次排列的四种天线结构。将所设计天线与传统天线进行了比较,结果表明所设计天线在s11参数、增益、指向性、回波损耗等方面具有优越性。所设计天线的增益远远优于传统天线。由于此类天线广泛用于医疗应用,因此特定吸收率(SAR)的测量变得非常关键。在不同的结构中观察到,狭缝、槽和截断的插入有助于改变天线的谐振频率,并有助于实现医疗应用所需的圆极化。设计的天线在增益、驻波比、回波损耗、辐射限值等方面均达到了最佳性能,均在FCC推荐的1.6 W/kg以内。

A study of CNN models for re-identification of vehicles 车辆再识别的CNN模型研究
M. Mathews, Sethilnathan T.
Vehicle Re-identification has evolved in recent times. Initially, clicking a single picture of a vehicle or a car was done manually, inviting the workforce to complete a specified task. With the growth in technology, the method and techniques in Vehicle Re-Id also have advanced, transforming from manual to automation. Surveillance cameras were used to capture vehicle images and retrieve information about a specific vehicle. Re-trieving and identifying the images of the vehicle is done using computer vision, the most important branch of computer science and artificial intelligence. Earlier, Vehicle Re-Id implemented a single algorithm on a dataset, making the corresponding result insufficient to determine its effects. This paper proposes a brief survey of multi-modal techniques and methods for vehicle re-identification and fingerprinting. The different attributes of the vehicle are considered for ANPR (Automatic number plate recognition) for identifying the number plate, focusing on the vehicle's details or features as the initial phase of identification, and then the vehicle number plate.
近年来,车辆再识别技术不断发展。最初,单击车辆或汽车的单个图片是手动完成的,邀请工作人员完成指定的任务。随着科技的发展,车辆识别的方法和技术也在不断进步,从手动向自动化转变。监控摄像头用于捕捉车辆图像并检索特定车辆的信息。重新检索和识别车辆的图像是使用计算机视觉来完成的,这是计算机科学和人工智能中最重要的分支。此前,Vehicle Re-Id在数据集上实现了单一算法,使得相应的结果不足以确定其效果。本文简要介绍了车辆再识别和指纹识别的多模态技术和方法。自动车牌识别(ANPR)考虑车辆的不同属性进行车牌识别,以车辆的细节或特征作为识别的初始阶段,然后识别车辆车牌。

Control of band gap of spin waves in width-modulated nanostrip using voltage-controlled magnetic anisotropy: Spin wave filter 利用压控磁各向异性控制宽度调制纳米带中自旋波带隙:自旋波滤波器
P. Bhattacharjee, S. Barman
A spin-wave filter that can operate at gigahertz frequencies may be built using a nanostrip magnonic-crystal waveguide with spatially periodic width modulation. Here, micromagnetic simulations are used to demonstrate the unique planar structure of magnonic-crystal waveguide composed of a magnetic material. In this structure, the permitted and forbidden bands of propagating dipole-exchange spin waves may be adjusted by periodic modulation of varying widths in thin-film nanostrips. A periodic nanostrip with a variable width, in contrast to a normal nanostrip with a fixed width, results in the production of forbidden bands (band gaps) as a consequence of spin-wave reflection by the periodic potential spurred on by long-range dipolar interactions. In this work, it is shown that the band structures of a width-modulated magnonic-crystal waveguide can be effectively tuned by controlling the magnetic anisotropy with a voltage. This research may provide a path toward the practical implementation of gigahertz-frequency, broadband spin wave filters.
利用空间周期宽度调制的纳米带状磁晶体波导,可以构建工作在千兆赫频率的自旋波滤波器。本文采用微磁模拟的方法,对磁性材料组成的磁晶体波导的独特平面结构进行了研究。在这种结构中,偶极交换自旋波的允许带和禁止带可以通过薄膜纳米带中不同宽度的周期性调制来调节。与固定宽度的普通纳米带相比,具有可变宽度的周期纳米带由于远程偶极相互作用激发的周期势的自旋波反射而产生禁带(带隙)。研究表明,通过电压控制磁各向异性,可以有效地调谐宽度调制磁晶体波导的能带结构。这项研究可能为实际实现千兆赫频率的宽带自旋波滤波器提供一条途径。

Design of Circularly Polarized Antenna for Vehicular GNSS Application 用于车载GNSS的圆极化天线设计
Amruta A. Nikam, Rupali B. Patil
For vehicle roof tops, a circular polarized square-shaped slot type antenna is proposed. The higher GNSS band which ranges from 1.559 to 1.606 GHz, is covered by the proposed antenna. The patch, square slot and chemfering edges of patch work together to produce circular polarization modes that significantly increase the antenna 3-dB axial ratio (AR). The AR for the antenna element in the simulations is 1.19 dB, the axial ratio bandwidth is 65 MHz, the VSWR is near about 1, the S11 parameter is less than −10 dB, and the gain is 8 dBic over the frequency range. It is made of poly vinyl chloride with dimensions of 54 mm x54 mm x 6.8 mm. The design procedure is explained in depth, as well as the antenna operating mechanism. A completely functional prototype was created and measured to confirm the proposed antenna's performance. When the measured voltage standing wave ratio (VSWR) and the S11 Parameter are compared with the observed data, a satisfactory agreement is found. Future multiband antenna designs for automotive communication could incorporate this antenna along with 4G/5G/6G band antenna.

Computer Based Detection of Alcoholism using EEG Signals 基于脑电信号的酒精中毒计算机检测
Garima Chandel, Ashish Sharma, Sonia Bajaj, Saweta Verma
Electroencephalogram (EEG) signals specify the electrical signals caused by neurons, which are very helpful to discriminate different activities of the human brain. In order to distinguish between the various functions of the human brain, electroencephalogram (EEG) signals describe the electrical signals produced by neurons. Traditional time domain or frequency domain methods of analysis are useless for any application since these signals exhibit nonstationary features. In this study, we examined a variety of more sophisticated time-frequency-based EEG signal component extraction algorithms for grouping and using it for automatic alcohol detection. The machine learning algorithms for alcohol EEG detection are proposed in this paper. It is made sense to conduct a thorough analysis of the decay of signs into recurrence subgroups using wavelet approach, DWT, and a set of quantifiable highlights that were subtracted from the EEG signals to address the circulation of wave coefficients. Furthermore, techniques like ICA and PCA are utilized for decreasing the feature vector dimensions, also an aspect of information and sign vectors which can be changed over completely to highlights vectors. Finally, a linear discriminant analysis (LDA) based classifier has been used after information decrease by reasonable determination technique and the classification performance has been measured by the parameters such as specificity, sensitivity and accuracy. These values in our work are 98.9%, 98.2% and 98.7% respectively.
脑电图(EEG)信号是由神经元发出的电信号,对区分人脑的不同活动非常有帮助。为了区分人脑的各种功能,脑电图(EEG)信号描述了神经元产生的电信号。传统的时域或频域分析方法对于任何应用都是无用的,因为这些信号具有非平稳特征。在这项研究中,我们研究了各种更复杂的基于时频的脑电信号成分提取算法,用于分组并将其用于自动酒精检测。本文提出了酒精脑电信号检测的机器学习算法。使用小波方法、DWT和从EEG信号中减去的一组可量化的亮点来解决波系数的循环问题,对符号衰减到递归子群进行彻底分析是有意义的。此外,利用ICA和PCA等技术来降低特征向量的维数,这也是信息和符号向量的一个方面,可以完全改变为高光向量。最后,通过合理的确定技术,将信息减少后,采用线性判别分析(LDA)分类器进行分类,并通过特异性、敏感性和准确性等参数来衡量分类性能。这些值在我们的工作中分别为98.9%、98.2%和98.7%。

R. K. Ajeena, Shatha Mohammed Hashim, F. A. Abdullatif
The intersection of cryptography and number theory has been encapsulated by studying the graph theory. The graphs have an important role in building the cryptographic schemes. In this work, a new contribution has been proposed by using the Mersenne numbers. These numbers are used to define new weighted graphs which named by Mersenne weight graphs (MWG). An efficient symmetric encryption (SE) scheme using MWG has been formed. The implementation results of a proposed algorithm are presented in this study. The security analysis of the proposed MWG-SE algorithm is discussed as well.

Detection Analysis of Abnormality in Kidney using Deep Learning Techniques and its Optimization 基于深度学习技术的肾脏异常检测分析及其优化
Vemu Santhi Sri, G. Lakshmi
Chronic kidney disease (CKD) is a global health burden that affects approximately 10% of the adult populationin the world. It is also recognized as the top 20 causes of death worldwide. Unfortunately, there is no cure for CKD houserver, it is possible to slow down its progression and mollify the damage by early diagnosis of the disease. Therefore, the use of modern computer-aided methods is necessary to aid the traditional CKD diagnosis system to be more efficient and accurate. Our proposed model is RCNN to classify the Tumour Area in the X-ray Kidney Image. Compare the Deep Learning Techniques of Mask RCNN Model with other models. Evaluated model is compared with other models by metrics of the Mask R-CNN model and Tuned Hyper parameter CNN Model. It gives Training accuracy of 0.9861 and testing accuracy of 0.9389 in the 5th Epochs of Mask RCNN Algorithm. And also, method uses More Metrics of PrecisionRecall, and F1-Score by comparing the RCNN Model and Hyper tuned CNN Model.
慢性肾脏疾病(CKD)是一种全球性的健康负担,影响着世界上大约10%的成年人。它也被认为是全球20大死亡原因之一。不幸的是,慢性肾脏病没有治愈的方法,但通过早期诊断可以减缓其进展并减轻损害。因此,使用现代计算机辅助方法来帮助传统的CKD诊断系统更加高效和准确是必要的。我们提出的模型是RCNN来对x线肾脏图像中的肿瘤区域进行分类。将Mask RCNN模型的深度学习技术与其他模型进行比较。通过Mask R-CNN模型和调谐超参数CNN模型的度量,将评估模型与其他模型进行比较。给出了Mask RCNN算法第5 epoch的训练准确率为0.9861,测试准确率为0.9389。此外,该方法通过比较RCNN模型和超调谐CNN模型,使用了PrecisionRecall和F1-Score的更多指标。

A perfect hashing to enhance the performance of Apriori algorithm 一个提高Apriori算法性能的完美哈希算法
Manuel Wilson, Malavika S. Nair, Pramod P. Nair, Anusree M
Data mining is the process of discovering patterns, relationships, and insights from large datasets using various computational techniques. Association Rules is a data mining method to find various relations between items in an itemset. The Apriori algorithm is a popular and classical algorithm for association rule mining. It has been observed that an increase in the number of candidate sets decreases the efficiency of the Apriori algorithm rapidly. To overcome this issue, the hashing technique, which uses a hash function to reduce the size of the candidate set itemset, is often used. In this paper, a perfect hashing function for a d-itemset is proposed. The efficiency of the Apriori algorithm is enhanced by using the hash function.
数据挖掘是使用各种计算技术从大型数据集中发现模式、关系和见解的过程。关联规则是一种数据挖掘方法,用于发现项目集中项目之间的各种关系。Apriori算法是一种流行的经典关联规则挖掘算法。已经观察到,候选集数量的增加会迅速降低Apriori算法的效率。为了克服这个问题,经常使用散列技术,它使用散列函数来减少候选集itemset的大小。本文给出了d项集的一个完美哈希函数。通过使用哈希函数,提高了Apriori算法的效率。
