FinFETs have displayed superior electrical behavior as the promising substitute to the planar devices with improved electrostatic control, though FinFETs have been encountered with key obstacles of device scaling for better performance. In this research work, a FinFET structure has been simulated at 10-nm technology node. The electrical performance of the device has been investigated at various gatelap lengths and with utilizing high-k gate insulating material in the device structure for understanding their influence on the device performance. Low subthreshold$sim 76.33$ mV/decade is obtained at gate-lap distance 0.5 nm. There have been obtained improvements in the ON to OFF current Ratio (ION/IOFF), Subthreshold swing (SS), and Drain Induced Barrier Lowering (DIBL) when the gate-lap length is varied. The results showed significant role of gate-lap length variation in the device parametrs. These research results are useful in guiding for scaling and design improvements of multi-gate device structures.
finfet表现出优异的电学性能,作为具有改进静电控制的平面器件的有希望的替代品,尽管finfet遇到了器件缩放以获得更好性能的关键障碍。在本研究中,我们在10nm技术节点上模拟了一个FinFET结构。研究了该器件在不同栅极长度下的电性能,并在器件结构中使用高k栅极绝缘材料,以了解它们对器件性能的影响。在栅极搭接距离0.5 nm处获得低亚阈值$ 76.33$ mV/ 10年。当栅极接圈长度变化时,开关电流比(ION/IOFF)、亚阈值摆幅(SS)和漏极诱导势垒降低(DIBL)得到了改善。结果表明,栅极搭接长度的变化对器件参数有显著影响。这些研究结果对多栅器件结构的缩放和设计改进具有指导意义。

Handwritten Signature Recognition is an important behavioral biometric which is used for numerous identification and authentication applications. There are two fundamental methods of signature recognition, on-line or off-line. On-line recognition is a dynamic form, which uses parameters like writing pace, change in stylus direction and number of pen ups and pen downs during the writing of the signature. Off-line signature recognition is a static form where a signature is handled as an image and the author of the signature is predicted based on the features of the signature. The current method of Off-line Signature Recognition predominantly employs template matching, where a test image is compared with multiple specimen images to speculate the author of the signature. This takes up a lot of memory and has a higher time complexity. This paper proposes a method of off-line signature recognition using Convolution Neural Network. The purpose of this paper is to obtain high accuracy multi-class classification with a few training signature samples. Images are preprocessed to isolate the signature pixels from the background/noise pixels using a series of Image processing techniques. Initially, the system is trained with 27 genuine signatures of 10 different authors each. A Convolution Neural Network is used to predict a test signature belongs to which of the 10 given authors. Different public datasets are used to demonstrate effectiveness of the proposed solution.
手写体签名识别是一种重要的行为生物识别技术,被广泛应用于身份识别和认证领域。签名识别有在线和离线两种基本方法。在线识别是一种动态形式,在签名书写过程中使用书写速度、笔尖方向变化、起笔次数等参数。离线签名识别是一种静态形式,将签名作为图像处理,并根据签名的特征预测签名的作者。目前的离线签名识别方法主要采用模板匹配,将测试图像与多个样本图像进行比较,推测签名的作者。这将占用大量内存,并且具有更高的时间复杂度。提出了一种基于卷积神经网络的离线签名识别方法。本文的目的是在训练签名样本较少的情况下获得高精度的多类分类。使用一系列图像处理技术对图像进行预处理,将签名像素从背景/噪声像素中分离出来。最初,该系统接受了来自10个不同作者的27个真实签名的训练。卷积神经网络用于预测测试签名属于10个给定作者中的哪一个。使用不同的公共数据集来证明所提出的解决方案的有效性。

Amorphous Hydrogenated Silicon ($alpha$-Si:H) has been a prevalent material in Thin Film Transistors (TFTs) since the inception of the technology. But due to their limited mobility they have been overhauled by alternative Amorphous Oxide Semiconductors (AOS). InGaZnO is one among them, which has variety of TFT applications. In this paper, simulation of two amorphous semiconductor TFTs have been carried out for analyzing their transport behavior and to compare the transport characteristics of the oxide TFTs. Simulation results reported that mobility have a high dependency on Urbach energy. Obtained maximum mobility 16 cm2/Vs from $alpha$-IGZO TFT is 73% higher than $alpha$-Si:H TFT. The results demonstrate the superiority of $alpha$-IGZO TFT mobility. The reported outcomes can advance the future oxide TFT Research and Development.

Visual secret sharing (VSS) scheme generates shares by encoding secret image into meaningless images. Human visual system is utilized to reveal secret image by share superimposition. XOR-based VSS scheme excels the visual performance of image and resolves the pixel alignment issue. Recently, the concept of meaningful shares is developed to share secret image to reduce the suspicion. However, a trade-off amongst share image quality and recovered secret image exist. This study presents VSS technique for meaningful shares using Boolean operation. Meaningful shares are generated by embedding different number of bits from secret and cover images. Likewise, lossless secret image is reconstructed using these meaningful shares while decoding. The combination of bits provide different visual quality of shares. Hence, in this paper, distinct bit combination is studied and optimum combination is reported.

Basis & Sensing Matrix as key effecting Parameters for Compressive Sensing 基和感知矩阵是影响压缩感知的关键参数

Compressive Sensing (CS) is a new approach for compression and reconstruction of compressed signals using very minute observations. These minute observations are also called the number of measurement. The basic benefits of CS are that the number of measurements which are required for proper reconstruction of the compressed signal is very less than the conventional method. If we go through the literature then, we get that for proper reconstruction of signal a theory is given by Shannon. This theory states that the sampling frequency must be higher than twice the highest frequency component in that signal. So the limitation of the conventional method is that it requires so much storage to store and a large bandwidth to transmit the data. So researchers came with a new idea which is termed as Compressive Sensing. Key effecting parameters which are very crucial for the compressive sensing is the Basis and Sensing matrix. The basic fact behind this approach is that the signal which is used for the compression and reconstruction must be Sparse. In the analysis which is done by us in this paper is that the change in these two matrices directly changes the value of SNR which will be obtained after compression and reconstruction using the compressive sensing. The work which is carried out based on three kinds of music signals with different cases of Basis and Sensing matrices.
压缩感知(CS)是一种利用极微小的观测值对压缩信号进行压缩和重构的新方法。这些微小的观察也被称为测量的次数。CS的基本优点是正确重建压缩信号所需的测量次数比传统方法少得多。如果我们回顾一下文献,我们就会发现Shannon给出了一个理论,用来对信号进行适当的重构。该理论指出,采样频率必须高于该信号中最高频率分量的两倍。因此,传统方法的局限性在于需要大量的存储空间和大的带宽来传输数据。因此,研究人员提出了一种新的想法,称为压缩感知。影响压缩感知的关键参数是基和感知矩阵。这种方法背后的基本事实是用于压缩和重构的信号必须是稀疏的。在本文所做的分析中,这两个矩阵的变化直接改变了压缩感知压缩重建后得到的信噪比值。该工作基于三种音乐信号,采用不同的基矩阵和传感矩阵。

The work which is carried out based on three kinds of music signals with different cases of Basis and Sensing matrices.","PeriodicalId":6575,"journal":{"name":"2018 International Conference on Advanced Computation and Telecommunication (ICACAT)","volume":"39 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74146905","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}

In our country every years, vermin causes a big economic harm. Hidden and normal herd of vermin attacks plants and field gradually but it causes huge harm in agriculture area and snakes like dangerous animal harms the farmers and local community too. However, these vermin and animal can’t be recognized in their curable stage and farmer could usage the pesticides and insecticides without knowing it. Then this could reduce the efficient state. So the paper presents here, we use the design of an Automated Ultrasonic-insects and animal repeller that constitute of an ultrasonic sensor, an motion-sensor, a GSM module and Arduino Uno board.This detect the sound of vermin by noticing ultrasonic signals propagated by provisioning event of vermin in crops. Then the presence of vermin proved by the motion sensor. Once presence of vermin confirmed by both the sensors Arduino Uno board start ultrasonic repeller by which the animal or insect goes away from that area and a memorandum will be sent by using GSM module and then farmer get ready for protecting it and they can use pesticides or insecticides according to their crops.
在我国,害虫每年都会造成很大的经济危害。隐藏和正常的害虫群逐渐攻击植物和田地,但它给农业地区造成了巨大的危害,蛇像危险的动物一样伤害了农民和当地社区。然而,这些害虫和动物在其治疗阶段无法被识别,农民可能在不知情的情况下使用农药和杀虫剂。这会降低有效态。因此,本文介绍了一种自动超声波驱虫器的设计,该驱虫器由超声波传感器、运动传感器、GSM模块和Arduino Uno板组成。这是通过注意害虫在作物中供应事件传播的超声波信号来检测害虫的声音。然后通过运动传感器证明了害虫的存在。一旦两个传感器都确认了害虫的存在,Arduino Uno板就会启动超声波驱虫器,动物或昆虫会离开该区域,并通过GSM模块发送备忘录,然后农民准备好保护它,他们可以根据他们的作物使用杀虫剂或杀虫剂。
