In this paper we have discussed the recognition of Meetei Mayek script with a Support Vector machine classifier. Distance profile feature and background directional distribution features are used as the feature vectors for training the SVM classifier. A comparative study is made on the performance between profile feature and background directional feature efficiency using SVM. Then a hybrid feature is generated by combining these two features and comparison of accuracy is done with the existing feature. Isolated handwritten documents are collected in some forms and experiment is performed over this dataset. For training the system the collection of documents is done from people from varying age group with different work background, so that the system can work well if we take the testing dataset from real world documents.

In search of more light on multiple access schemes used in under water acoustic (UWA) communications, through this work, we try to investigate the possibility of using hybrid multiple access scheme, named single carrier frequency division multiple access-interleave division multiple access (SC-FDMA-IDMA). Orthogonal frequency division multiplexing (OFDM) concept is used to fight against long time-delay spreads at the same time interleave division multiple access (IDMA) has a simple multi-user detection (MUD) receiver structure. So OFDM combined with IDMA is a favorable technique for underwater channel. Aquatic transmissions are expensive in terms of power consumed so in this work SC-FDMA-IDMA is analyzed in terms of Bit error rate (BER). It is observed that SC-FDMA-IDMA performs quite near to other multiple access schemes. So SC-FDMA-IDMA is a better choice for Acoustic channel.
为了寻找更多关于水声(UWA)通信中使用的多址方案,通过这项工作,我们试图研究使用混合多址方案的可能性,即单载波频分多址-交错多址(SC-FDMA-IDMA)。正交频分复用(OFDM)的概念用于对抗长时延传播,同时交错分多址(IDMA)具有简单的多用户检测(MUD)接收机结构。因此,OFDM与IDMA相结合是一种较好的水下信道技术。水上传输功耗高,因此本文从误码率的角度对SC-FDMA-IDMA进行分析。观察到SC-FDMA-IDMA的性能与其他多址方案相当接近。因此SC-FDMA-IDMA是声学信道较好的选择。

Living beings inherently have the ability to differentiate languages as a part of human intelligence. Language Identification (LID) had been a science fiction in 1970's but today; it has been deployed in practical usage. The prosodic features of a speech are relatively simpler in their structure and are accredited to be very affective in some Language Recognition (LR) or LID tasks; irrespective of these features to be biased on numerous factors, as speaker's way of speaking, the culture and background of speaker. As because prosodic features is regardless very important, researchers against their heavy work have proven many methods for its normalization, making the feature inventory very large. In this book, we have used the maximum likelihood detector for the GMM-UBM based language model to analyze and identify various prosodic attributes in the LID tasks The entire wok includes a series of experiments on several speech corpus and different classification or/and identification technique. In an overview, we may assert that the book explores various experimental datasets, for, performance analysis of LID system with News speech and Natural Conversation speech and Joint Factor Analysis for LR on prosodic featured models.
作为人类智力的一部分,生物天生具有区分语言的能力。语言识别(LID)在20世纪70年代曾是科幻小说,但在今天;该方法已在实际应用中得到应用。语音的韵律特征在结构上相对简单,在一些语言识别(LR)或LID任务中被认为是非常有效的;不论这些特征如何都要受到许多因素的影响,如说话人的说话方式、说话人的文化和背景。由于韵律特征非常重要,研究人员在繁重的工作中已经证明了许多对韵律特征进行归一化的方法,使得韵律特征库非常庞大。在本书中,我们使用了基于GMM-UBM的语言模型的最大似然检测器来分析和识别LID任务中的各种韵律属性。整个工作包括在几个语音语料库和不同的分类或/和识别技术上的一系列实验。在概述中,我们可以断言,本书探索了各种实验数据集,用于新闻语音和自然会话语音的LID系统的性能分析以及LR在韵律特征模型上的联合因素分析。

Cloud computing has made it feasible to access various IT resources through a high speed network from anywhere in the world. Constant increasing demand of cloud computing is equally popular in consumers as well as providers. But along with advancement every technology is also associated with some ill effects. On same path, cloud computing also accompanies a serious issue with it and that issue is energy consumption. In this paper Firefly Algorithm has been selected as a proposed bio-inspired approach to perform load balancing to reduce energy consumption in cloud data center. Further, the results are compared with Particle Swarm optimization Algorithm (PSO). The energy consumed in case of Firefly Algorithm is less than energy consumed in PSO Algorithm.
云计算使得从世界任何地方通过高速网络访问各种it资源成为可能。不断增长的云计算需求在消费者和供应商中同样受欢迎。但是随着技术的进步,每一项技术也会带来一些不良影响。在同样的道路上,云计算也伴随着一个严重的问题,那就是能源消耗。本文选择萤火虫算法作为一种生物启发的方法来执行负载平衡,以降低云数据中心的能耗。并与粒子群优化算法(PSO)进行了比较。萤火虫算法所消耗的能量小于粒子群算法所消耗的能量。

A design of dual wide band circularly polarized circular patch with parasitic ring and defected ground structure. By using the coaxial probe feed 45° with respect to the axis of the two stub plane of the patch then excellent circular polarization (CP) is achieved. The antenna is designed with a double-layer structure, comprising a circular patch with two rectangular stubs along the diameter direction and two half parasitic rings right above it. Both patch are separated by a circular substrate FR-4 (εr = 4.3). The ground plane also defected; two circular slots are cut away at the ground plane. By using the defected ground structure (DGS) the band width also increased. This proposed antenna work at dual wide band that are 6.90 to 7.10 GHz (200 MHz) and 8.06 to 9.22 GHz (1.16 GHz). The % band width is 2.69% and 13.42% and Gain is 6.2 dB and 8.3 dB respectively. The return loss & gain of the proposed antenna show that it has promising characteristics for various C-band and X- band (7-12 GHz) radar and satellite applications. The design is being simulated using CST (computer simulation technology) software.

In this paper, we present a new, simple multiband micro strip antenna mounted on a compact, no ground portion of a system circuit board of a mobile phone with a low profile of 15mm×20mm×11.2mm. The proposed antenna is 3D with an open-ended loop antenna having coaxial feed. It operates at two wide band frequencies, so that it covers multiband such as GSM850/900/ DCS1800/ PCS1900/ UMTS2100/ LTE2300 /2500/2700-3100 radar and radio navigation operation. It provides multiple resonant modes at 900, 1800, 2450, and 2900MHz. It supports the applications of a cellular system and IEEE Wireless Local Area Network (WLAN) and radio navigation and provides lightweight, low cost, multiband functionality. Performance analysis shows improved radiation efficiency, antenna gain and radiation pattern along with a sufficient reduction in return loss. Detailed design considerations of the proposed antenna are described. The simulation analysis is performed by using IE3D software.

The electrocardiogram provides a physician with a view of the heart's activity through electrical signals generated during the cardiac cycle and measured with external electrodes. Because of the high mortality rates of heart diseases faithful detection and classification of ECG arrhythmias is essential for the treatment of patients in the clinics. Arrhythmia classification is one of the most important research domains of computer aided medical systems. The authors have made an exploratory investigation of the classification of ECG signal. DWT (Discrete Wavelet Transform) method has been used to determine the wavelet coefficients which were associated with five features. The features were ranked by using class separability criteria.
