Audio signal deblurring using singular value decomposition (SVD) 基于奇异值分解的音频信号去模糊
Nilesh M. Patil, M. Nemade
Deblurring is the process of removing blurring artifacts from signals, such as blur caused by noise, defocus aberration or motion blur. Blind Convolution for signal separation is an area of research in the field of signal processing from last few decades. Similarly, image deblurring and restoration has also been an area of research using different techniques like Blind Signal Separation (BSS), Singular Value Decomposition (SVD) combined with DCT, DWT, Differential Evolution Optimization. However, very little research is been done on audio deblurring. In this paper, we proposed an idea for deblurring of an audio signal using SVD. At the end, we also computed root mean square error (RMSE), normalized root mean square error (NRMSE) and peak signal-to-noise ratio (PSNR) between the original audio signals and the signals retrieved after applying SVD.
去模糊是从信号中去除模糊伪影的过程,例如由噪声、离焦像差或运动模糊引起的模糊。盲卷积信号分离是近几十年来信号处理领域的一个研究方向。同样,图像去模糊和恢复也是一个研究领域,使用不同的技术,如盲信号分离(BSS),奇异值分解(SVD)结合DCT, DWT,差分进化优化。然而,关于音频去模糊的研究很少。本文提出了一种利用奇异值分解对音频信号进行去模糊处理的方法。最后,我们还计算了原始音频信号与应用SVD后检索到的信号之间的均方根误差(RMSE)、归一化均方根误差(NRMSE)和峰值信噪比(PSNR)。

R. Prasad, A. Krishnamoorthy
Electric Vehicles (EVs) acceptance in the global market is highly dependent on the operating time, and frequency of charging. This paper deals with designing a zero emission solar EV with inbuilt solar battery charging system. The power sources integrated with EV model to recharge the battery bank are renewable in nature. A mathematical framework on the availability, accommodation and power contribution by the solar power source in the EV model are presented. Simulation study of the solar EV model is carried out in Matlab / Simscape environment to understand the improvement attained in the operation time by employing solar power source. The solar EV model operation time is further analyzed under real-time conditions using PVsyst real-time simulator. A comparative study has been carried out on the Matlab and PVsyst results obtained for the developed solar EV model. The results indicate an overall enhancement in operation time besides the difference in the operation time obtained during standard test conditions (STC) and real-time conditions under various operating speeds of the vehicle.

An algorithm to recognize the adversaries in self organizing networks inspired from the human immune system 一种在自组织网络中识别对手的算法,灵感来自人体免疫系统
Juniorika Lyngdoh, H. Kalita
Self organizing networks is a network formed by automatic configuration without any central control where by only the authorized nodes are allowed to join the network. As the system scales, it is practically impossible for each individual user to independently select an optimal service provider without conflicting with others. Hence, many research efforts of self organization framework inspired by biological systems have sprung up in the recent years in wireless telecommunication and networking. Inspired by the ecosystem some biologic models are applied in networks. These models facilitate the dynamic networking and out perform traditional methods. In this paper we will describe the working of the human immune system and defense body mechanism of the body. Though we know that our immune system may be strong to defend against any diseases but how does it recognize those pathogens and keep the body secure will be discussed in this paper. We have proposed a model and an algorithm to recognize the adversaries keep the network secured.
自组织网络是通过自动配置而形成的网络,没有任何中央控制,只允许授权的节点加入网络。随着系统的扩展,每个用户在不与其他用户发生冲突的情况下独立选择最优服务提供商实际上是不可能的。因此,近年来在无线通信和网络领域涌现出许多受生物系统启发的自组织框架研究。受生态系统的启发,一些生物学模型被应用于网络。这些模型便于动态组网,取代了传统方法。本文将介绍人体免疫系统的工作原理和机体的防御机制。虽然我们知道我们的免疫系统可能很强,可以抵御任何疾病,但它是如何识别这些病原体并保持身体安全的,这将在本文中讨论。我们提出了一个识别攻击者的模型和算法,以保证网络的安全。

Modified Round Robin algorithm (MRR) 改进的轮循算法(MRR)
Montek Singh, R. Agrawal
CPU Scheduling Algorithms form the basic and fundamental concepts of Operating Systems. A scheduling algorithm is used to produce effective switches between the processes present in the ready queue. Round Robin algorithm is one among the many CPU scheduling algorithms where every process executes for a given time quantum (TQ). Therefore the system efficiency and performance are completely dependent on the value of TQ. If this value is static in nature, then the CPU performance decreases. This paper uses the dynamic TQ to create an efficient Round Robin Algorithm. This goal was achieved by using the concept of median. The traditional RR algorithm does not take priority under the consideration, which further reduces the CPU performance. The proposed algorithm improves the efficiency of the traditional RR algorithm by considering all the factors like priority, burst time and arrival time of the processes to arrange them in the ready queue and generating TQ accordingly; which effectively reduces the Waiting time, Turn-around time, and the number of context switches. The paper also presents a detailed comparison between the proposed algorithm and existing algorithms.
CPU调度算法构成了操作系统的基本概念。调度算法用于在就绪队列中存在的进程之间产生有效的切换。轮循算法是许多CPU调度算法中的一种,其中每个进程在给定的时间量子(TQ)内执行。因此,系统的效率和性能完全取决于TQ的值。如果这个值是静态的,那么CPU性能会下降。本文利用动态TQ创建了一种高效的轮询算法。这个目标是通过使用中值的概念来实现的。传统的RR算法没有考虑优先级,进一步降低了CPU性能。该算法综合考虑了进程的优先级、突发时间、到达时间等因素,将其排在就绪队列中,并相应产生TQ,提高了传统RR算法的效率;这有效地减少了等待时间、周转时间和上下文切换的次数。本文还对本文提出的算法与现有算法进行了详细的比较。

Deblurring techniques — A comprehensive survey 去模糊技术-综合调查
Y. R. Sankaraiah, S. Varadarajan
Nowadays the digital images are so common in various fields including computer vision, medicine, military, astronomy, industrial automation and etc. But in most of the cases where the capturing of digital images is so crucial, the process of capturing of images is difficult. The objects may be moving or to catch the object the capturing device may need to move fast or the capturing device may respond a little late which result in a blurred image. As just mentioned blurring may be resulted by various factors independently or cumulatively the inverse operation is not just simple. The solution must invert all artifacts imposed in blurring process. In this paper, a review of various methods used to perform the inverse operation was presented. Some of the methods presented are finally compared using different types of blurred images by calculating peak signal to noise ratio and structural similarity.
如今,数字图像在计算机视觉、医学、军事、天文、工业自动化等各个领域都很常见。但是,在大多数情况下,捕捉数字图像是如此重要,捕捉图像的过程是困难的。所述对象可能正在移动,或者为了捕获所述对象,所述捕获设备可能需要快速移动,或者所述捕获设备可能响应稍晚,从而导致图像模糊。正如刚才提到的,模糊可能是由各种因素单独或累积造成的,逆操作并不简单。解决方案必须反转在模糊处理过程中施加的所有伪影。本文综述了用于进行逆运算的各种方法。最后通过计算峰值信噪比和结构相似度,对不同类型的模糊图像进行了比较。

Besides Effective area and field distribution are also described briefly.","PeriodicalId":6589,"journal":{"name":"2017 IEEE International Conference on Power, Control, Signals and Instrumentation Engineering (ICPCSI)","volume":"1 1","pages":"1296-1298"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85440444","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}
