Empirical evaluation of image reconstruction techniques 图像重建技术的经验评价
B. Priya, Dr. A. Suruliandi
Image reconstruction is the process of manipulating an image to increase the amount of information perceived by a human eye. In this paper most popular filtering techniques have taken for comparison, that are Non Local Mean method, Particle filtering and Markov random fields. The Original NL Mean method replaces a noisy pixel by the weighted average of pixels with related surrounding neighbourhoods. In order to accelerate the algorithm; the filters are used to eliminate unrelated neighborhoods from the weighted average. The particle filtering technique will give statistical behavior of the image. The most appropriate window or neighborhood shape and size to estimate the image intensity in a given position. One attempt is to do perform filtering by selecting the neighboring pixels in a random fashion but without taking image structure into account. MRFs can be used as parametric models for the probability distribution of intensity levels in an image. The resulting framework explores optimally spatial dependencies between image content towards variable bandwidth image reconstruction. The results of techniques Non Local Mean method, Particle Filters and Markov random fields are compared by using two parameters such as PSNR and MSE values for the reconstructed images.Markov Random Fields method provides a better result when compare to Nonlocal mean method and Particle Filter.
图像重建是对图像进行处理以增加人眼所能感知到的信息量的过程。本文比较了非局部平均法、粒子滤波和马尔可夫随机场等常用滤波技术。原始的NL均值方法用具有相关邻域的像素的加权平均来代替有噪声的像素。为了加速算法;该滤波器用于从加权平均值中消除不相关的邻域。粒子滤波技术将给出图像的统计行为。最合适的窗口或邻域形状和大小,以估计在给定位置的图像强度。一种尝试是通过随机选择相邻像素来执行过滤,但不考虑图像结构。磁共振成像可以用作图像中强度水平概率分布的参数模型。由此产生的框架探索图像内容之间的最佳空间依赖关系,以实现可变带宽图像重建。利用重构图像的PSNR和MSE值对非局部平均法、粒子滤波和马尔可夫随机场技术的结果进行比较。与非局部均值法和粒子滤波法相比,马尔可夫随机场法具有更好的滤波效果。

Continuous monitoring of heart rate variability and haemodynamic stability of an automobile driver to prevent road accidents 对汽车驾驶员的心率变异性和血流动力学稳定性进行连续监测,以防止交通事故的发生
S. Emarose, R. Asokan, D. Valayaputtur
A methodology to continuously monitor the heart rate variability (HRV) and haemodynamic stability of an automobile driver is essential for both the driver and the co-passengers. In this paper, we discuss the maximum physiological parameters that an oximeter installed in the steering wheel of an automobile can measure. A pulse oximeter which is normally used for measuring blood oxygen saturation is exposed to magnetic fields to obtain the blood viscosity, which is an essential parameter to keep the body haemodynamically stable. RGB color band analysis is made on the oximeter output in order to obtain the electro-cardiac signals from the Green band. Measurement of respiration rate is done by amplitude and frequency modulation of the light signal [1]. In case of cardiac arrest, the vehicle is changed to cruise control mode and the measured parameters will be sent to any nearby hospitals for assistance using GPS. The RFID tags are also used to communicate to the nearby vehicles to alert other drivers for emergency assistance. Each and every vehicle is equipped with automatic external defibrillator (AED) with detailed instructions on how to operate the AED, in order to defibrillate a person in cardiac arrest.
一种持续监测汽车驾驶员心率变异性(HRV)和血流动力学稳定性的方法对驾驶员和同乘人员都是必不可少的。本文讨论了安装在汽车方向盘上的血氧仪所能测量的最大生理参数。通常用于测量血氧饱和度的脉搏血氧仪在磁场中暴露以获得血液粘度,这是保持人体血液动力学稳定的重要参数。对血氧仪输出进行RGB色带分析,得到绿色波段的心电信号。呼吸速率的测量是通过光信号的幅度和频率调制来完成的[1]。在心脏骤停的情况下,车辆将切换到巡航控制模式,测量的参数将通过GPS发送到附近的任何医院寻求帮助。RFID标签还用于与附近的车辆通信,以提醒其他司机进行紧急援助。每辆车都配备了自动体外除颤器(AED),并配有如何操作AED的详细说明,以便为心脏骤停的人除颤器。

On recognizing ID based attacks using environs and beam forming approach for wireless sensor networks 基于环境和波束形成方法的无线传感器网络ID攻击识别研究
M. Rajesh, G. R. Gangadevi, R. Sugavanam
Sensor networks are a promising innovative technology to enable economically viable solutions to a variety of applications, for example pollution sensing, structural integrity monitoring, and traffic monitoring. A large subset of sensor network applications requires security, especially if the sensor network protects or monitors critical infrastructures. Unfortunately, the simplicity and low-cost of the sensors eases cloning and create a sibling of compromised nodes by attackers. These ID based assaults are the entry point to a large span of insidious attacks. In such circumstances, an adversary uses the credentials of a compromised node to surreptitiously introduce anomalies into the network. These infected nodes are then used to launch a variety of attacks that subvert the goal of the sensor application, and the operation of the underlying protocols. The detection of such attacks in a wireless sensor network is therefore a fundamental problem. Intension of this work is insinuate a new environs based beamforming approach (ESMS) to detect both clone and Sybil attack with the same strategy.
传感器网络是一项很有前途的创新技术,可以为各种应用提供经济可行的解决方案,例如污染传感、结构完整性监测和交通监测。大部分传感器网络应用都需要安全性,特别是在传感器网络保护或监视关键基础设施的情况下。不幸的是,传感器的简单性和低成本使攻击者容易克隆并创建一个受感染节点的兄弟节点。这些基于ID的攻击是大量潜伏攻击的入口点。在这种情况下,攻击者使用受损节点的凭据秘密地将异常引入网络。然后,这些受感染的节点被用来发起各种攻击,破坏传感器应用程序的目标和底层协议的操作。因此,在无线传感器网络中检测此类攻击是一个基本问题。本研究的重点是提出一种新的基于环境的波束形成方法(ESMS),以相同的策略检测克隆攻击和西比尔攻击。

Capacity enhancement in MCCDMA-MIMO system using iterative water filling approach based power distribution method 基于迭代充水方法的mcdma - mimo系统容量增强功率分配方法
A. Sundhar, P. Dananjayan
Multicarrier CDMA (MC-CDMA) technology is the one of the major key solution for the development in future wireless communication systems. The further improvement of data transmission with the limited bandwidth is achieved by multiple-input multiple-output (MIMO) structure. The MC-CDMA system is subject to limiting factors such as multiple-access Interference (MAI) and inters carrier interference (ICI) and these interferences diminish attainable throughput performance. The transmission strategy to avoid the interference noise is by its power allocation to each user. The Game theory is an effective tool for examining power control problem in the MCCDMA technology with imperfect channel state information. The water filling algorithm in game theory is used to allocate proper power for every sub-channel in order to improve channel capacity. In this paper iterative water filling power control algorithm to allocate power for each user is adopted in MCCDMA-MIMO system. The water filling algorithm distributes power among all users with the help of SINR that is received by the transmitter instead of getting full channel state information. The capacity enhancement in MCCDMA is evaluated with and without water filling algorithm and further performance improvements are analyzed by transmitting through MIMO system.
多载波CDMA (MC-CDMA)技术是未来无线通信系统发展的主要关键解决方案之一。多输入多输出(MIMO)结构进一步提高了有限带宽下的数据传输性能。MC-CDMA系统受到诸如多址干扰(MAI)和载波干扰(ICI)等限制因素的影响,这些干扰会降低可实现的吞吐量性能。为了避免干扰噪声,传输策略是将功率分配给每个用户。博弈论是研究不完全信道状态信息下MCCDMA技术功率控制问题的有效工具。采用博弈论中的充水算法,为每个子通道分配适当的功率,以提高通道容量。本文在MCCDMA-MIMO系统中采用迭代充水功率控制算法对每个用户进行功率分配。充水算法不是获取全信道状态信息,而是利用发射机接收到的信噪比将功率分配给所有用户。评估了采用充水算法和不采用充水算法时MCCDMA的容量增强情况,并通过MIMO系统传输分析了进一步的性能改进。

Improving classification performance for the minority class in highly imbalanced dataset using boosting 在高度不平衡的数据集中使用boosting提高少数类的分类性能
M. Abouelenien, Xiaohui Yuan, P. Duraisamy, Xiaojing Yuan
Data imbalance is a common property in many medical and biological data and usually results in degraded generalization performance. In this article, we present a novel boosting method to address two important questions in learning from imbalanced dataset: how to maximize the performance of classifying the minority instances without compromising the performance for the majority instances? and how to select training instances to achieve a comprehensive representation of the data distribution and avoid high computational time? Our method maximizes the usage of the available samples with priority given to the minority samples. The base classifiers are weighted with their sensitivities derived from the training examples. Using synthetic and real-world datasets, we demonstrated the performance improvement of our method in both sensitivity and accuracy without major reduction in specificity. In contrast to AdaBoost, our method took much less time, which makes it applicable in real-world problems that have large amount of data.

An embedded system for determining arrhythmia 一种用于检测心律失常的嵌入式系统
Aditi Agarwal, P. A., S. S, Shashidhara L
With increasing use of technology to aid human health care has opened up lot many challenges and opportunities in the field of telecommunication engineering. In this paper an effort is made for the development and implementation of wireless body area networks on an embedded platform. Wearable sensors placed at different organs of the body and signals are captured and transmitted using WBAN (Wireless Body Area Network). A microcontroller is used to coordinate the process. The parameters considered here are the heartbeat and the temperature level of the body. The microcontroller monitors the values of these two parameters using sensors interfaced to it for all possible cases of arrhythmia (slow, fast and irregular heart beat). On exceeding the threshold values in case of slow or fast heart beat the GSM modem interfaced to it is triggered, to send warning or alert messages to the doctor. And simultaneously monitoring the temperature levels of the patient will help us in monitoring the irregular heart beat.
随着技术对人类医疗保健的应用越来越广泛,电信工程领域面临着许多挑战和机遇。本文致力于在嵌入式平台上开发和实现无线体域网络。可穿戴传感器放置在身体的不同器官,信号通过无线身体区域网络(WBAN)捕获和传输。微控制器用于协调整个过程。这里考虑的参数是心跳和体温水平。微控制器使用与之接口的传感器监测这两个参数的值,以检测所有可能的心律失常(慢、快和不规则心跳)。在超过阈值的情况下,心跳慢或快的GSM调制解调器接口被触发,向医生发送警告或警报信息。同时监测病人的体温水平可以帮助我们监测不规则的心跳。
