Study of the effect of music on autonomic nervous system of human being through the analysis of Heart rate variability (HRV) signals is a very recent area of research. The present paper considers the effect of seven different types of music stimuli on a single subject. The data of the HRV signals are subjected to a recently developed technique known as `frequency-delay plot'. The quantification is done by `ellipsoid fit' and allied five different types of quantification measures. Such results of quantification are then analyzed by the method of 'randomized block ANOVA. It is proved that all the different types of music stimuli have different effects on ANS of the subject, and that the effects are significantly different. Moreover the five different measures also do differ significantly on the music data. Finally to test which music signal affects ANS most, we consider, as population, the totality of all data corresponding to different types of songs and different types of measures taken. By considering the data of individual song under all measures as data of a sample, we calculate the interval of confidence of the population mean and the population variance with the help of each sample mean and sample variance at 0.95 level of confidence. It is proved that the length of confidence interval for population mean as well as for population variance is minimum only in the case of song1. In other words, it means that song1 is the most effective one on ANS of the subject.
通过分析心率变异性信号来研究音乐对人体自主神经系统的影响是近年来的一个研究领域。本文考虑了七种不同类型的音乐刺激对单一受试者的影响。HRV信号的数据受到最近开发的一种称为“频率延迟图”的技术的影响。量化是通过“椭球拟合”和相关的五种不同类型的量化措施完成的。然后用随机分组方差分析方法对量化结果进行分析。实验证明,不同类型的音乐刺激对被试的ANS有不同的影响,且效果有显著性差异。此外,这五种不同的测量方法在音乐数据上也存在显著差异。最后,为了检验哪种音乐信号对ANS影响最大,我们将不同类型的歌曲和所采取的不同类型的措施对应的所有数据的总和视为总体。将所有度量下的单个歌曲数据视为一个样本的数据,在0.95的置信水平下,利用每个样本均值和样本方差计算总体均值和总体方差的置信区间。证明了只有在song1的情况下,总体均值和总体方差的置信区间长度是最小的。换句话说,这意味着song1是该主题中最有效的一个。

Most challenging part in RADAR system is to getting better accuracy and resolution. In this paper, we have designed a radar transmitter and receiver using direct sequence spread spectrum for improving range accuracy.

Number Plate Recognition (NPR) and Character Segmentation (CS) play a major role in one of the intelligent transportation system. This paper identifies a number plate identification system for Indian plates. This method consists of two main modules: NPR and CS. In NPR, histogram equalization is employed to solve the low contrast and dynamic-range problems and Eight-Neighbors technique is proposed to filter the unwanted areas in the image. In CS, the hybrid binarization technique is proposed to effectively segment the characters in the dirt NP. The system captures the images of the vehicles at various backgrounds and conditions using a digital camera. The results are highly appreciable.

To analyze lung sound by auscultation method requires substantial clinical experience, a fine stethoscope and good listening skills. The lung itself cannot generate sound if there is no airflow; pressure differences between structures within the thorax. The type of lung sound can be known by listening to the lung sound. The timing, repeatability and shape of crackles are important parameter for diagnosis. In this paper, we aim to detect and classify crackle to find deformities in lungs.

Acoustic echo is one of the most important issues in communication. It creates disturbance in day-to-day communication. This echo can be cancelled using adaptive filters which are governed by adaptive algorithms. Right from the introduction of Least Mean Square (LMS) algorithm, over the years, a lot of research has been done in this field in order to develop new algorithms which can effectively drive the filter to give better performance. In this review paper, we have studied and discussed all the previous work done on these algorithms in relation to acoustic echo cancellation. This paper contains the basic review of all such existing algorithms as well as their merits and demerits. It covers the basic algorithms like LMS algorithm, Recursive Least Square algorithm as well as their modified versions like Normalized Least Mean Square algorithm, Fractional Least Mean Square algorithm, Filtered-x Least Mean Square algorithm etc. Finally, a tabular comparison has been given towards the end of the paper in order to conclude the discussion.

Routing in mobile ad hoc network (MANETs) for groups should aim at providing reliable and robust multicast routes to the group members against link and node failures with mobility conditions. This paper propose an agent-based multicast routing scheme like On-Demand Multicast Routing Protocol (ODMRP) which can be more suitable for Ad Hoc network but D-ODMRP Destination driven On-Demand Multicast Routing Protocol is used to reduce the number of nodes to be added in the forwarding group. D-ODMRP introduces the features into the existing on demand process of multicast forwarding structure in MANET that builds a backbone in the form of a reliable mesh and finds multicast routes. Mobile autonomous agent technique for intrusion detection system in MANET has been proposed where agents are fired from a source node which traverses each node randomly and detect the malicious node. The link failure are detected and repaired by nearby nodes. This paper illustrate three types of performance analysis they are packet delivery ratio against number of multicast group, power consumption of nodes verses number of nodes & network area verses no of nodes and found that proposed system is better.
在移动自组网(manet)中,针对移动条件下的链路和节点故障,需要为组成员提供可靠、健壮的多播路由。本文提出了一种更适合Ad Hoc网络的基于agent的组播路由方案,即点播组播路由协议(ODMRP),但采用了D-ODMRP目的驱动的点播组播路由协议,以减少转发组中需要添加的节点数量。D-ODMRP将现有的按需组播转发结构的特点引入到MANET中,以可靠网格的形式建立主干并查找组播路由。提出了一种用于MANET入侵检测系统的移动自主代理技术,该技术从源节点发射代理,随机遍历每个节点并检测恶意节点。链路故障由附近的节点检测和修复。本文对分组发送比与组播组数、节点功耗与节点数、网络面积与节点数进行了三种性能分析,结果表明本文提出的系统具有较好的性能。

we have proposed an Energy efficient leader election in MANET for Intrusion detection service (IDS). As MANET don't have any centralized controller, the leader election in each cluster becomes very important. The purpose of the elected leader is to serve the IDS for the entire cluster. Our leader election is based on Reputation value and energy level of each node. We have simulated in NS2 environment and shown the comparison of energy consumption or Residual energy of nodes having fixed transmission range with the proposed adaptive energy scheme. Adaptive energy scheme adjusts the range of transmission of each node based on the maximum distance between nodes in each cluster. Energy of each node is conserved as compared to node having fixed transmission range. Thus the leader can serve the cluster for longer duration of life, increasing the percentage of alive nodes, conserving energy of node.
针对入侵检测服务(IDS),提出了一种高效节能的MANET领导者选举方法。由于MANET没有任何集中控制器,因此每个集群的leader选举变得非常重要。选出的leader的目的是为整个集群的IDS提供服务。我们的领导人选举是基于信誉值和每个节点的能量水平。我们在NS2环境下进行了仿真,并展示了固定传输范围节点的能耗或剩余能量与所提出的自适应能量方案的比较。自适应能量方案根据每个集群中节点之间的最大距离来调整每个节点的传输范围。与固定传输距离的节点相比,每个节点的能量是守恒的。因此leader可以为集群服务更长的生命周期,增加存活节点的百分比,节约节点的能量。

Switching median filters outperform standard median filters in the removal of impulse noise. This is because, it considers only the noisy pixels and performs filtering operation on that pixels without considering noise-free pixels. The Boundary Discriminative Noise Detection (BDND) filter is proven to operate effectively under different impulse noise models. It initially classifies pixels into three groups as (a) low intensity impulse noise (b) high intensity impulse noise (c) uncorrupted pixels. Then noise detection and filtering steps are performed. Pixel misclassification is the main drawback of BDND filtering algorithm. So we modify the filtering step of this algorithm and named it as modified boundary discriminative noise detection (MBDND). The two modifications incorporated are as follows: (1) Expansion of filtering window. (2) Incorporating spatial and intensity information. By introducing these modifications into the algorithm, it is found that there is increase in the performance and the quality of image has improved. Results are compared with other median filters like Center Weighted Median Filter (CWMF), Progressive Switching Median Filter (PSMF), Adaptive Threshold Median Filter (ATMF) and it is found that MBDND performs well even at high noise density (90%).
开关中值滤波器在去除脉冲噪声方面优于标准中值滤波器。这是因为,它只考虑有噪声的像素,而不考虑无噪声的像素,对这些像素进行滤波操作。边界判别噪声检测(BDND)滤波器在不同的脉冲噪声模型下都能有效地工作。它最初将像素分为三组:(a)低强度脉冲噪声(b)高强度脉冲噪声(c)未损坏像素。然后进行噪声检测和滤波步骤。像素误分类是BDND滤波算法的主要缺点。为此,我们对该算法的滤波步骤进行了改进,并将其命名为改进边界判别噪声检测(MBDND)。引入的两个修改是:(1)扩大过滤窗口。(2)结合空间和强度信息。通过在算法中引入这些改进,算法的性能得到了提高,图像的质量得到了改善。将结果与中心加权中值滤波器(CWMF)、渐进切换中值滤波器(PSMF)、自适应阈值中值滤波器(ATMF)等其他中值滤波器进行比较,发现MBDND即使在高噪声密度(90%)下也表现良好。

The demand for high data rate applications is on the rise in the recent years which is due to the rapid growth in wireless communication. The existing technologies like Wireless Fidelity (Wi-Fi) and Bluetooth cannot support such high data rates because of their narrowband and also they drain the battery at rapid pace. Ultra Wide Band (UWB) system differs from conventional narrow band system by transmitting short duration pulses occupying a large bandwidth with power levels almost comparable to that of the noise floor. Any communication technology which uses more than 500 MHz of bandwidth in the range of 3.1 to 10.6 GHz is defined as UWB. The transmitter side of impulse radio consists of pulse generator and modulator. The pulse generator is used to generate the required short pulse in the desired range of frequency. The proposed pulse generator is of pulse combination type impulse generator which is fully digital constructed with MOS Current Mode Logic (MCML) as Fine Delay Elements without using passive components thus reducing circuit complexity. The proposed pulse generator is designed using 90 nm technology with 1 V supply voltage. The maximum power consumption is 330 μW. The output voltage shape complies with FCC regulation.
近年来,由于无线通信的快速发展,对高数据速率应用的需求呈上升趋势。现有的无线保真(Wi-Fi)和蓝牙等技术无法支持如此高的数据速率,因为它们的带宽很窄,而且电池的消耗速度很快。超宽带(UWB)系统与传统窄带系统的不同之处在于,它发射的脉冲持续时间短,占用大带宽,其功率水平几乎与噪声底相当。任何在3.1至10.6 GHz范围内使用超过500mhz带宽的通信技术都被定义为超宽带。脉冲无线电的发射端由脉冲发生器和调制器组成。脉冲发生器用于在期望的频率范围内产生所需的短脉冲。该脉冲发生器为脉冲组合型脉冲发生器,采用MOS电流模式逻辑(MCML)作为精细延迟元件,不使用无源元件,实现了全数字化结构,降低了电路复杂度。该脉冲发生器采用90nm技术,电源电压为1v。最大功耗330 μW。输出电压形状符合FCC规定。

The existing technologies like Wireless Fidelity (Wi-Fi) and Bluetooth cannot support such high data rates because of their narrowband and also they drain the battery at rapid pace. Ultra Wide Band (UWB) system differs from conventional narrow band system by transmitting short duration pulses occupying a large bandwidth with power levels almost comparable to that of the noise floor. Any communication technology which uses more than 500 MHz of bandwidth in the range of 3.1 to 10.6 GHz is defined as UWB. The transmitter side of impulse radio consists of pulse generator and modulator. The pulse generator is used to generate the required short pulse in the desired range of frequency. The proposed pulse generator is of pulse combination type impulse generator which is fully digital constructed with MOS Current Mode Logic (MCML) as Fine Delay Elements without using passive components thus reducing circuit complexity. The proposed pulse generator is designed using 90 nm technology with 1 V supply voltage. The maximum power consumption is 330 μW. The output voltage shape complies with FCC regulation.","PeriodicalId":149965,"journal":{"name":"2014 International Conference on Communication and Signal Processing","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124394807","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}

There is a speedy increase in the usage of World Wide Web presently. To improve the reliability and responsiveness of internet, the performance and functions of routing protocol that makes the internet work needs to be increased. Routing protocol specifies the communication between the routers. The router communicates the path information first among the immediate neighbors and then throughout the network. The path traversed by the routers build the topology of the entire network. Border Gateway Protocol is the ubiquitous exterior gateway routing protocol that exchanges routing information between autonomous systems in the internet backbone. We enquire multicores as the platform for routing application that uses Border Gateway Protocol (BGP) as a routing protocol. The paper implements multithreaded and parallel processing BGP using Dynamic Task Scheduling (DTS) with Round Robin scheduling technique. Round Robin Scheduling technique selects the queues in a round robin fashion from which the packet will be taken for transmission. We analyze the performance of BGP on a simulated multicore environment.
目前万维网的使用正在迅速增加。为了提高互联网的可靠性和响应能力,需要提高路由协议的性能和功能。路由协议指定路由器之间的通信。路由器首先在近邻之间传递路径信息,然后在整个网络中传递路径信息。路由器所经过的路径构成了整个网络的拓扑结构。边界网关协议是普遍存在的外部网关路由协议,用于在互联网骨干网中的自治系统之间交换路由信息。我们询问多核作为使用边界网关协议(BGP)作为路由协议的路由应用程序的平台。本文采用动态任务调度(DTS)和轮循调度技术实现了BGP的多线程并行处理。轮循调度技术以轮循的方式选择队列,数据包将从队列中取出进行传输。我们分析了BGP在模拟多核环境下的性能。
