Software Defined Radio is an all new technology being developed in the 21st century. The major practical problem in digital communication systems is channel distortion which causes errors due to Intersymbol Interference (ISI). Channel equalisers are used in digital communication receivers to mitigate the effects of inter symbol interference (ISI) and inter user interference in the form of co-channel interference (CCI) and adjacent channel interference (ACI) in the presence of additive white Gaussian noise (AWGN). An equaliser uses a large part of the computations involved in the receiver. Equalizers are designed to reduce the ISI as much as possible and to minimize the effect of the additive noise for better demodulation. This paper presents a software defined radio module with fuzzy adaptive equalizer. The main focus will be on reconfigurable software defined radio (SDR) because the reconfiguration of mappings is very difficult to be achieved in hardware Here Fuzzy Equalizers are designed in which step size is controlled through Fuzzy Rules. Results are shown for input & output SNR at different iterations which concludes that the coefficients of Fuzzy Adaptive Equalizer are updated, correspondingly output SNR has been increased. The output and input Signal to Noise Ratio is then calculated for different Iterations.
软件无线电是21世纪发展起来的一项全新技术。数字通信系统中主要的实际问题是由于码间干扰(ISI)引起的信道失真。信道均衡器用于数字通信接收机,以减轻在加性高斯白噪声(AWGN)存在的情况下,同信道干扰(CCI)和相邻信道干扰(ACI)形式的符号间干扰(ISI)和用户间干扰(ISI)的影响。均衡器使用接收器中涉及的大部分计算。均衡器的设计是为了尽可能地减少ISI,并尽量减少加性噪声的影响,以获得更好的解调。提出了一种带有模糊自适应均衡器的软件无线电模块。由于映射的重构很难在硬件上实现,因此本文将重点讨论可重构软件定义无线电(SDR)。本文设计了模糊均衡器,通过模糊规则控制步长。结果表明,模糊自适应均衡器的系数得到了更新,输出信噪比相应提高。然后计算不同迭代的输出和输入信噪比。

Particle Swarm Optimization (PSO) and Biogeography Based Optimization (BBO) are most popular swarm based optimization algorithms those have shown impressive performance over other Evolutionary Algorithms (EAs). Yagi-Uda is one of most widely antenna designs used at High Frequency (HF) and Ultra High Frequency (UHF) due its high gain, low cost and constructional ease. Designing a Yagi-Uda antenna involves determination of wire-element lengths and their spacings in between them those bear highly complex and non-linear relationships with antenna gain, impedance and Single Lobe Level (SLL) at a particular frequency of operation. In this paper, a comparative study between PSO and BBO is presented for faster optimization of antenna designs for maximum gain. The best antenna designs are tabulated and average of 10 monte-carlo simulations are plotted for BBO, PSO and their combinational iterative performances in the ending sections.
粒子群优化(PSO)和基于生物地理的优化(BBO)是最流行的基于群体的优化算法,它们比其他进化算法(ea)表现出令人印象深刻的性能。Yagi-Uda天线具有高增益、低成本和结构简单等优点,是高频和超高频应用最广泛的天线设计之一。设计Yagi-Uda天线需要确定线元长度和它们之间的间距,这些长度和间距与天线增益、阻抗和特定工作频率下的单瓣电平(SLL)具有高度复杂的非线性关系。为了更快地优化天线设计以获得最大增益,本文对粒子群算法和BBO算法进行了比较研究。最后给出了最佳天线设计,并绘制了BBO、PSO及其组合迭代性能的10次蒙特卡罗模拟的平均值。

The last decade has witnessed an ample amount of research work in tele-monitoring that involves transmission of biomedicai signals through wireless media. Exchange of bio-signals amongst various hospitals and diagnostic centres requires high level of security and reliability while transmitting through internet. Watermarking is added "ownership" information in multimedia content to prove authenticity, verify signal integrity, and achieve control over the copy process. The Photoplethysmography (PPG) is a very sensitive and significant diagnostic tool in the medical world to analyse the functions of the human heart. This analysis is done in a simple manner than the most common way of using electrocardiography to detect various cardio-vascular diseases by measuring the electrical activity of the heart. The variance in its characteristics also provides important information about cardiac diseases incorporated with the same cause and raises alarm about heart malfunctioning. The present work proposes a Lifting Wavelet Transformation based method of binary watermark embedding within the Photoplethysmographic (PPG) signal as well as the process of extracting watermark from the PPG signal. In this approach, the generated watermarked signal having an acceptable level of imperceptibility and distortion is compared to the original PPG signal. Finally, a comparative study of Pulse Transit Time (PTT), pulse transit time to the foot of the pulse (PTTf) and Pulse amplitude (AMP) between the recovered PPG signal and different levels of wavelet based de-noised recovered PPG signal is done. Telecardiology is achieved by successful transmission of the watermarked PPG signal with reversibility of watermark to avoid discrepancies in data to deliver precise treatment.
在过去的十年中,人们在远程监测方面进行了大量的研究工作,其中涉及到通过无线媒体传输生物医学信号。在各医院和诊断中心之间交换生物信号需要高度的安全性和可靠性,同时通过互联网传输。水印是在多媒体内容中加入“所有权”信息来证明真实性,验证信号的完整性,实现对拷贝过程的控制。Photoplethysmography (PPG)是医学界分析人类心脏功能的一种非常敏感和重要的诊断工具。这种分析比最常用的通过测量心脏电活动来检测各种心血管疾病的心电图方法更简单。其特征的差异也提供了与相同原因合并的心脏疾病的重要信息,并引起了心脏功能障碍的警报。本文提出了一种基于提升小波变换的二值水印嵌入光容积脉搏波(PPG)信号的方法以及从PPG信号中提取水印的方法。在这种方法中,与原始PPG信号相比,生成的具有可接受的不可感知性和失真水平的水印信号。最后,对比研究了恢复后的PPG信号与不同小波降噪后恢复后的PPG信号的脉冲传输时间(PTT)、脉冲到脉冲脚的传输时间(PTTf)和脉冲幅度(AMP)。心电学是通过成功传输带水印的PPG信号来实现的,水印具有可逆性,避免了数据的差异,从而实现了精确的治疗。

Mobile Ad-hoc network is a decentralized, self-organizing network. At present trend the MANET become one of the most important wireless communication mechanisms among all other. Unlike traditional network, MANET does not have any fixed infrastructure. Every single node in the network work as both a receiver as well as transmitter and node can communicate without any access point However, due to the mobile infrastructure MANET suffer from the variety of attacks. These attacks occur due to the misbehaviour/selfish nodes which can degrade the network performance. To develop a strong security scheme, the secure route selection is analyzed under varying degree of misbehavior nodes. Eventually AODV(Ad-Hoc on Demand Distance Vector), GRP(Gathering based routing protocol) and OLSR(Optimized Link State Routing) protocol meets the above scheme at different WLAN(Wireless Local Area Network) parameter physical characteristics 802.11a Orthogonal Frequency Division Multiplexing(OFDM) and 802.11g (extended rate PHY) over a range of scenario we analyzed or tested the performance.
移动自组织网络是一种分散的、自组织的网络。在目前的发展趋势中,无线局域网已成为最重要的无线通信机制之一。与传统网络不同,MANET没有任何固定的基础设施。网络中的每个节点既可以作为接收端,也可以作为发送端,在没有接入点的情况下也可以进行通信。然而,由于移动基础设施的存在,MANET受到各种攻击。这些攻击是由于错误行为/自私节点导致的,这会降低网络性能。为了开发一种强安全方案,分析了不同程度错误行为节点下的安全路由选择。最终AODV(Ad-Hoc on Demand Distance Vector)、GRP(Gathering based routing protocol)和OLSR(Optimized Link State routing)协议满足上述方案在不同WLAN(无线局域网)参数物理特性下的802.11a正交频分复用(OFDM)和802.11g(扩展速率PHY)的一系列场景下进行了性能分析或测试。

With the development of remote sensing imaging technology, the satellite information includes more abundant data, and the quality of satellite cloud image had achieved great progress. The satellite cloud images contain the valuable information for weather forecasting and early prediction of different atmospheric disturbances such as typhoons, hurricanes etc. The processing of content-based satellite cloud image has become one of the most important tasks for using the satellite cloud image information for continuous research. Content-based satellite cloud image processing and information retrieval is a very important problem in image processing and analysis field. In this research, a Content-Based Image Retrieval (CBIR) system has been developed using color, texture and shape as retrieval features from the satellite image repository. To extract the grey level/color properties of an image, histogram values have been used. Four functions of texture features have used such as (Entropy, Energy, correlation and contrast) and the shape features (area, perimeter and metric) have been extracted using the morphological operations. The images and the extracted feature vectors were stored in the database. Results obtained from the processing demonstrate the usability of proposed system.

In this paper a global heuristic search evolutionary optimization technique called craziness based particle swarm optimization (CRPSO) is used for the design of 8th order infinite impulse response (IIR) band stop (BS) digital filter. The proposed CRPSO based approach has closely mimicked the particle's behaviour in a swarm which results in better exploration and exploitation in multidimensional search space. Performance of the proposed optimization technique is compared with some well accepted evolutionary algorithms such as PSO and real coded genetic algorithm (RGA). From the simulation study it is demonstrated that the proposed optimization technique CRPSO surmounts RGA and PSO, in terms of better quality output response, faster convergence speed and stability.

Mapping the competency of personnel with different level of expertise, skill set, and experience in professional fields is a tough, complex but essential task. In this work, we have considered an Engineering College with moderate number of faculties with different level of experience, expertise and research exposure. Here we have considered the load assignment to the faculties at the beginning of a semester as the competency mapping task. Each faculty having capabilities of teaching different subjects out of the total set of papers needs to take about two theory papers with or without laboratory component. The decisive factors for subject assignment may be depth of knowledge, sincerity, class management, contribution towards research, text book publication. Further preference of the faculty member should be considered with top priority unless there are some valid constraints. Again the teaching personnel in a department hold different designations and different administrative responsibility, therefore each of them cannot be assigned equal hours of teaching load. The decisive factors are considered as objectives to be optimized and multi-objective particle Swarm optimization (MOPSO) is employed to perform the competency mapping task. The simulation results show the effectiveness of this approach.
绘制专业领域中具有不同水平的专业知识、技能和经验的人员的能力图是一项艰巨、复杂但必不可少的任务。在这项工作中,我们考虑了一所工程学院,其师资数量适中,经验、专业知识和研究水平各不相同。在这里,我们把在学期开始时分配给教员的负荷看作是能力映射任务。每个有能力教授不同学科的教师需要写两篇理论论文,包括或不包括实验部分。课题分配的决定因素可能是知识深度、诚意、班级管理、对研究的贡献、教科书出版。除非有一些有效的限制,否则应优先考虑教师的进一步偏好。同样,一个部门的教学人员有不同的名称和不同的行政责任,因此每个人都不能被分配相同的教学负荷。将决定因素作为优化目标,采用多目标粒子群算法(MOPSO)进行能力映射。仿真结果表明了该方法的有效性。

Nowadays mobile devices, represented mainly by smartphones, are used by million of people around the world. These smartphones include a large set of hardware capabilities and sensors which allow to improve the user interaction and content delivery. The sensors allow to gather extra information about the user situation and therefore to create location & context aware mobile apps. However, sensors usage involves energy consumption, which is also one of the smartphone's biggest limitations; in addition, these devices also have storage and memory constraints, and slow processors compared to a conventional computer. Recently, there is an emerging tendency consisting in lessen these limitations by implementing the complex computations and data storage in external entities such as cloud computing. This article presents the fundamentals for developing an energy-aware middleware for the support of context & location aware mobile apps with cloud computing interaction. This middleware can increase up to three times the smartphone battery performance when using the GPS receiver, and in the cloud can perform the extraction of places of interest from a list of GPS fixes uploaded by the smartphone.
如今,以智能手机为代表的移动设备在世界各地被数百万人使用。这些智能手机包含大量硬件功能和传感器,可以改善用户交互和内容传递。传感器可以收集有关用户情况的额外信息,从而创建位置和上下文感知移动应用程序。然而,传感器的使用涉及能源消耗,这也是智能手机最大的限制之一;此外,这些设备也有存储和内存限制,与传统计算机相比,处理器速度较慢。最近出现了一种新的趋势,即通过在云计算等外部实体中实现复杂的计算和数据存储来减少这些限制。本文介绍了开发能源感知中间件的基本原理,该中间件用于支持具有云计算交互的上下文和位置感知移动应用程序。当使用GPS接收器时,这个中间件可以将智能手机电池的性能提高三倍,并且在云端可以从智能手机上传的GPS修复列表中提取感兴趣的地点。

This article presents the fundamentals for developing an energy-aware middleware for the support of context & location aware mobile apps with cloud computing interaction. This middleware can increase up to three times the smartphone battery performance when using the GPS receiver, and in the cloud can perform the extraction of places of interest from a list of GPS fixes uploaded by the smartphone.","PeriodicalId":445333,"journal":{"name":"2012 World Congress on Information and Communication Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114492945","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}

Common cost estimation methods focus on subjective experience, but fuzzy Neural Network Technology makes relatively accurate estimates because it collects the respective advantages of the fuzzy theory and neural networks. This research constructs a model of neural networks and fuzzy neural network model comparing with mature COCOMO II model, and concludes that fuzzy neural network in software cost estimation is superior to neural network model. It is a good estimation model. The experimental calculation shows that the software cost estimation model constructed by fuzzy neural networks combines multiple advantages. It can be used for real estate information management system quickly and efficiently, and provides a basis for the development and maintenance of similar projects in the future.
常用的成本估算方法侧重于主观经验,而模糊神经网络技术由于综合了模糊理论和神经网络各自的优点,估算相对准确。本研究构建了神经网络模型和模糊神经网络模型,并与成熟的COCOMO II模型进行比较,得出模糊神经网络在软件成本估算方面优于神经网络模型的结论。这是一个很好的估计模型。实验计算表明,模糊神经网络构建的软件成本估算模型综合了多种优点。可以快速高效地用于房地产信息管理系统,为今后类似项目的开发和维护提供依据。

Wireless Sensor Network (WSN) based systems are becoming mainstream and are getting deployed in critical business environments. Thus, any failure of such a system due to potential security attacks would have serious business implications for an enterprise. So far the community has looked into the security of WSN in isolation and to our knowledge there is no study looking into end-to-end security issues of a WSN based business solution, such as, datacenter monitoring. This paper provides an insight into the security issues in the deployment of WSN based solutions and briefly outlines the possible security measures that can be applied.
基于无线传感器网络(WSN)的系统正在成为主流,并被部署在关键的商业环境中。因此,由于潜在的安全攻击而导致的此类系统的任何故障都将对企业产生严重的业务影响。到目前为止,社区已经孤立地研究了WSN的安全性,据我们所知,还没有研究基于WSN的业务解决方案的端到端安全问题,例如数据中心监控。本文深入分析了基于WSN的解决方案部署中的安全问题,并简要概述了可以应用的可能的安全措施。
