CIC filter for sample rate conversion in software defined radio 用于软件无线电采样率转换的CIC滤波器
Devarpita Sinha, Sanjay Kumar
Software Defined Radio (SDR) or Software Radio is one of the most important technologies for the modern wireless communication system. The vision of SDR is implementing a single radio that can emulate any radio signal of evolving or already existing wireless standards. It can be done simply by updating software without replacing the underlying hardware platform. Again, different air interface requires different sample rate for baseband processing. So, Sample Rate Conversion (SRC) is an important functionality of SDR. SRC includes both sample rate reduction or decimation and sample rate increase or interpolation. But in both the cases Comb Integrator Comb (CIC) filter plays an important role as anti-aliasing filter (in case of decimation) or anti-imaging filter (in case of interpolation). This paper describes the basic structure of CIC filter and illustrates important parameters to characterize this filter. Consequently it focuses on implementation of CIC filter in decimator and interpolator. This paper also tries to find a technique to improve the characteristics of this filter and point out some problems associated with it.
软件无线电(Software Defined Radio,简称SDR)是现代无线通信系统的重要技术之一。SDR的愿景是实现一个单一的无线电,可以模拟任何无线电信号的发展或已经存在的无线标准。只需更新软件即可,而无需更换底层硬件平台。同样,不同的空中接口需要不同的基带处理采样率。因此,采样率转换(SRC)是SDR的一个重要功能。SRC包括采样率降低或抽取和采样率增加或插值。但在这两种情况下,梳状积分器梳状(CIC)滤波器作为抗混叠滤波器(在抽取的情况下)或抗成像滤波器(在插值的情况下)发挥重要作用。本文介绍了CIC滤波器的基本结构,并举例说明了表征该滤波器的重要参数。因此重点研究了CIC滤波器在抽取器和插值器中的实现。本文还试图找到一种改进该滤波器特性的技术,并指出了存在的一些问题。

Feature extraction algorithm for estimation of agriculture acreage from remote sensing images 遥感影像农业面积估计的特征提取算法
Pooja G. Mate, Kavita R. Singh, A. Khobragade
Feature plays a vital role in classification task. In this context, feature selection and feature extraction is an essential module for the classification of any kind of data, namely textual database, image database consisting of simple images or complex images like remote sensing images collected through satellites. Use of particular features is domain and problem specific. For instance, very specific features different from others might be needed for classifying agricultural areas or crops within agricultural fields. Identification of such specific features pertaining to satellite images exhibiting its agriculture coverage is a challenging problem. Therefore features related to satellite images are studied and different methods or techniques used for optimal feature selection have also been studied and analyzed.
特征在分类任务中起着至关重要的作用。在这种背景下,特征选择和特征提取是任何一种数据分类的重要模块,无论是文本数据库、简单图像组成的图像数据库,还是通过卫星采集的遥感图像等复杂图像。特定特性的使用是特定于领域和问题的。例如,可能需要与其他特征不同的非常具体的特征来对农业区域或农业领域内的作物进行分类。识别与显示其农业覆盖范围的卫星图像有关的这些具体特征是一个具有挑战性的问题。因此,对卫星图像相关的特征进行了研究,并对用于最优特征选择的不同方法或技术进行了研究和分析。

Design and analysis of resource allocation techniques in cloud partitions 云分区中资源分配技术的设计与分析
Shweta T. Ukande, R. Dharmik
Cloud computing is efficient and scalable technology. Cloud is nothing but a pool of resources, which provides miscellaneous services to different kind of users. Users send requests to cloud when they want service from cloud. When request is received at cloud, resource is allocated to that user and respective service is provided. As it is efficient and scalable, there is a rapid growth in cloud users so the load of requests on cloud is increased. This load should be balanced properly, to improve the system performance. Usually, virtualization concept is used to reduce load of requests at cloud. Strategy of allocating resource to user, which involves load balancing techniques, has to be good enough to provide maximum resource utilization and throughput. In this article a better load balancing algorithm is proposed.
云计算是一种高效且可扩展的技术。云只是一个资源池,它为不同类型的用户提供各种服务。当用户需要云服务时,他们会向云发送请求。当在云上接收到请求时,将资源分配给该用户并提供相应的服务。由于它是高效和可伸缩的,因此云用户快速增长,因此云上的请求负载也随之增加。此负载应适当平衡,以提高系统性能。通常,虚拟化概念用于减少云上的请求负载。为用户分配资源的策略必须足够好,以提供最大的资源利用率和吞吐量,这涉及到负载平衡技术。本文提出了一种更好的负载均衡算法。

Classification of remote sensing image using SVM kernels 基于SVM核的遥感图像分类
Neha V. Mankar, A. Khobragade, M. Raghuwanshi
With reference to the literature worldwide, it is obvious that Support Vector Machine (SVM), a machine learning algorithm has proven records for excellent results regarding Classification of Image. But, Remote Sensing Images are considered as most complex in nature as far as classification is concern. Supervised classification of Remote Sensing Images needs more precise machine learning models, which will be fast and efficient. SVM do satisfy researchers all over the world as far as Remote Sensing Images are concern. Basically, SVM is non-parametric statistical learning based model, which acts like binary classifier. SVM represents a group of superior machine learning algorithms, where it decomposes the parameter of the problem into a quadratic optimization technique. Hence, SVM is used to locate optimum boundaries between classes, which in return generalize to unseen samples with least error among all possible boundaries separating two classes. SVM uses density estimation function for developing easy and efficient learning parameters. Like other supervised algorithms, SVM also undergo into Training, Learning and Testing Phase for classifying any image. Besides all parameters, training sample selection and optimization is crucial part that affects the classification accuracy of remote sensing images. We need to address this issue in our project so as to devise noble algorithm or approach, which could make SVM, a more robust statistical learning model.
参考世界范围内的文献,很明显,支持向量机(SVM)这一机器学习算法在图像分类方面取得了优异的成绩。但是,就分类而言,遥感图像被认为是本质上最复杂的。遥感图像的监督分类需要更精确的机器学习模型,这将是快速有效的。就遥感图像而言,支持向量机确实满足了世界各地的研究人员。支持向量机基本上是基于非参数统计学习的模型,其作用类似于二值分类器。支持向量机是一组优秀的机器学习算法,它将问题的参数分解为一种二次优化技术。因此,使用支持向量机来定位类之间的最优边界,从而在分离两类的所有可能边界中推广到误差最小的未见样本。支持向量机使用密度估计函数来开发简单有效的学习参数。与其他监督算法一样,SVM也要经过训练、学习和测试三个阶段对任意图像进行分类。除了这些参数之外,训练样本的选择和优化是影响遥感图像分类精度的关键部分。我们需要在我们的项目中解决这个问题,从而设计出高贵的算法或方法,使SVM成为一个更鲁棒的统计学习模型。

A review on method of stream data classification through tree based approach 基于树的流数据分类方法综述
Jyoti Wagde, Prarthana A. Deshkar
Today, rapid growth in hardware technology has provided a means to generate huge volume of data continuously. Most of the real time data stream application such as network monitoring, stock market and URL filtering we found that the volume of data is so large that it may be impossible to store the data on disk. Furthermore, even if the data can be stored on the disk, the volume of the incoming data may be so large that it may be difficult to process any particular record more than once. These large volumes of data need to be mined for getting interesting patterns and relevant information out of it. Consequently, we need further enhanced technique for, data stream classification while dealing with various challenges which are not solved by traditional data mining methods such as large volume, concept drift, and concept evolution.
如今,硬件技术的快速发展为持续产生海量数据提供了手段。在网络监控、股票市场和URL过滤等实时数据流应用中,我们发现数据量非常大,可能无法将数据存储在磁盘上。此外,即使数据可以存储在磁盘上,传入的数据量也可能非常大,以至于很难多次处理任何特定的记录。需要对这些大量数据进行挖掘,以便从中获得有趣的模式和相关信息。因此,在处理大数据量、概念漂移、概念演化等传统数据挖掘方法无法解决的问题的同时,还需要进一步提高数据流分类技术。

Wavelet-based tolerance near set approach in classifying hand images: A review 基于小波的公差近集方法在手部图像分类中的应用
Ankita J. Gakare, Kavita R. Singh, J. Peters
A wavelet-based tolerance Nearness Measure (tNM) makes possible to measure fine-grained changes in shapes in pairs of images. The image correspondence utilizes image matching tactics to establish closeness between two or more images. This is one of the central tasks in computer vision. The problem considered that how can we measure the nearness or apartness of digital images. In case when it is important to detect conversion in the contour, position, and approximal orientation of bounded regions. However, the solution of this problem is that results from an application of anisotropic (direction dependent) a tolerance and wavelets near set approach to detecting affinities in pairs of images. It has been shown that tolerance near sets can be used in a concept-based approach to discovering correspondences between images. In this paper we are showing detail survey on near set approach. By near set approach an effective means of images is nothing but grouping together that correspond to each other relative to diminutive similarities in the features of bounded regions in the images.
基于小波的公差接近度测量(tNM)可以测量成对图像中形状的细粒度变化。图像对应利用图像匹配策略来建立两个或多个图像之间的紧密性。这是计算机视觉的核心任务之一。该问题考虑了如何测量数字图像的距离或距离。在需要检测有界区域的轮廓、位置和近似方向转换的情况下。然而,这个问题的解决方案是应用各向异性(方向相关)、容差和小波近集方法来检测成对图像的亲和力。研究表明,容差近集可以用于基于概念的方法来发现图像之间的对应关系。本文对近集方法进行了详细的研究。通过近集方法,一种有效的图像方法是将图像中有界区域的特征相对于微小的相似性相对应的图像分组在一起。

The image correspondence utilizes image matching tactics to establish closeness between two or more images. This is one of the central tasks in computer vision. The problem considered that how can we measure the nearness or apartness of digital images. In case when it is important to detect conversion in the contour, position, and approximal orientation of bounded regions. However, the solution of this problem is that results from an application of anisotropic (direction dependent) a tolerance and wavelets near set approach to detecting affinities in pairs of images. It has been shown that tolerance near sets can be used in a concept-based approach to discovering correspondences between images. In this paper we are showing detail survey on near set approach. By near set approach an effective means of images is nothing but grouping together that correspond to each other relative to diminutive similarities in the features of bounded regions in the images.","PeriodicalId":355852,"journal":{"name":"2016 World Conference on Futuristic Trends in Research and Innovation for Social Welfare (Startup Conclave)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133915225","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}
