Analysing connectivity patterns and centrality metrics for opportunistic networks 分析机会网络的连接模式和中心性指标
Muhammad Arshad Islam, M. Iqbal, Muhammad Aleem, Z. Halim
Network centrality measures are used to identify important and influential nodes in any network. Several centrality measures are proposed in literature for static networks however these measures cannot be used for routing purpose in opportunistic networks as opportunistic networks are dynamic in nature. Opportunistic networks utilise pocket switching for routing messages where each device attempts to forward its messages to a suitable next node. Appropriate decision making for the selection of the forwarder node is crucial for the performance of a routing protocol in opportunistic networks. In any opportunistic network, some node play more important role in the routing process than the rest of the network. In this paper, we have analysed metrics that can be used to simplify the centrality measure computation in opportunistic networks. We have investigated the relationship between these node (ego) characteristics with centrality measures that are computed using novel network transformations. The aim of the transform mechanisms is to aggregate the link between any two nodes in a way that strongly relates the nodes which frequently come in contact with each other. Our experiment show that ego characteristics can be used to estimate centrality measures for dense opportunistic networks.
网络中心性度量用于识别任何网络中重要和有影响力的节点。文献中提出了几种用于静态网络的中心性度量,但是这些度量不能用于机会网络中的路由目的,因为机会网络本质上是动态的。机会主义网络利用口袋交换路由消息,其中每个设备尝试将其消息转发到合适的下一个节点。在机会网络中,选择合适的转发器节点对路由协议的性能至关重要。在任何机会网络中,总有一些节点在路由过程中扮演着比其他节点更重要的角色。在本文中,我们分析了可以用来简化机会网络中中心性度量计算的度量。我们研究了这些节点(自我)特征与使用新型网络变换计算的中心性度量之间的关系。转换机制的目的是聚合任意两个节点之间的链接,这种方式将经常相互接触的节点强关联起来。我们的实验表明,自我特征可以用来估计密集机会主义网络的中心性度量。

Effect of coupling on software faults: An empirical study 耦合对软件故障影响的实证研究
Sajid Anwer, Ahmad Adbellatif, M. Alshayeb, Muhammad Shakeel Anjum
Software product's quality is one of the important aspects that affect the user, the developer, and the product. Measuring quality in the early phases of the project life cycle is a major goal of project planning. Accordingly, several research studies have been proposed to measure the software product quality attributes. In this paper, we empirically study the impact of afferent coupling (Ca), efferent coupling (Ce) and coupling between object (CBO) metrics on fault prediction using bivariate correlation. We built a prediction model using these metrics to predict faults by using multivariate logistic linear regression. A case study of an open source object oriented systems is used to evaluate the correlation between coupling metrics and faults. The results indicate that the efferent coupling (Ce) is a better indicator for fault prediction than afferent coupling (Ca) and CBO (coupling between object)
软件产品的质量是影响用户、开发人员和产品的重要方面之一。在项目生命周期的早期阶段度量质量是项目计划的主要目标。因此,人们提出了对软件产品质量属性进行度量的研究。本文采用二元相关方法,对输入耦合(Ca)、输出耦合(Ce)和目标间耦合(CBO)指标对故障预测的影响进行了实证研究。利用这些指标建立预测模型,利用多元逻辑线性回归对故障进行预测。本文以一个面向对象的开源系统为例,分析了耦合度量与故障之间的关系。结果表明,相对于传入耦合(Ca)和对象间耦合(CBO),传出耦合(Ce)是更好的故障预测指标。

An Efficient Dynamic Round Robin algorithm for CPU scheduling 一种高效的CPU调度动态轮循算法
M. U. Farooq, Aamna Shakoor, A. Siddique
The efficiency of embedded systems mainly depends on the process scheduling policy of operating systems running on them. Better scheduling algorithms make a system fast using less resources for small time. Out of some important scheduling algorithms, Round Robin algorithm is much efficient. But its efficiency fairly depends on choosen time quantum. In this paper, we have developed an efficient Round Robin algorithm using Dynamic Time Quantum. Some such systems have already been developed but they take advantage of other algorithms and their running time is much higher due to sorting of processes which is practically impossible. So, our goal is to reduce running time of an algorithm along with efficiency constraints such as context switches, average waiting and turnaround times. Lower the context switches, average waiting and turnaround times; higher the efficiency of an operating system and thus better embedded system. In the last section of this paper, we will present a comparison of our system with previously developed algorithms.
嵌入式系统的运行效率主要取决于运行在其上的操作系统的进程调度策略。更好的调度算法使系统在更短的时间内以更少的资源运行速度更快。在一些重要的调度算法中,轮循算法是效率最高的。但其效率很大程度上取决于所选择的时间量子。本文提出了一种基于动态时间量子的高效轮询算法。一些这样的系统已经被开发出来,但它们利用了其他算法,由于对过程进行排序,它们的运行时间要高得多,这实际上是不可能的。因此,我们的目标是减少算法的运行时间以及诸如上下文切换、平均等待和周转时间等效率约束。降低上下文切换、平均等待和周转时间;更高的操作系统效率,从而更好的嵌入式系统。在本文的最后一部分,我们将把我们的系统与以前开发的算法进行比较。

Assessment of quality of rice grain using optical and image processing technique 利用光学和图像处理技术评价稻米品质
Z. Parveen, Muhammad Anzar Alam, Hina Shakir
Rice is the most favorable and most consuming food for human being in all over the world and researchers are working to improve the quality of rice. The quality measurement of rice is also important because it is consumed as food as well as it is used for milling process in the national and international market. Many researchers have already worked on the quality of grain and proposed different techniques to characterize the quality of rice. Chalky is whiteness part in the rice grain and it is one of the most important parameter that is used to evaluate the quality of rice grain. We proposed an image processing technique using extended maxima operator to detect the chalky area in the rice. We also calculated the dimensions and color to classify rice grains. The experiment was performed on 22 sample images of rice grain to test the proposed method and was validated using visual inspection.

Comparison of different de-noising techniques for removal of poison noise from cervical X-Rays images 不同去噪技术去除宫颈x线图像中毒性噪声的比较
Muhammad Asim, M. Akram, A. A. Salam
Digital X ray images normally suffer from poor quality and one of the main reason is the presence of poison noise which is added in X rays images during acquisition process. Different de-noising techniques have been presented in literature for enhancement of x ray images. This paper presents a comparative study for extraction of noise from X-Rays images. The comparison has been done for bilateral filtering, Dual Tree Complex Wavelet Transform, Gaussian filter, Wiener filter and Non-Local Mean filters and evaluation of these techniques have been done using cervical X-Ray images from NHANES-II database. The significance of each technique has been evaluated using different performance measures.
数字X射线图像通常质量较差,其中一个主要原因是在采集过程中添加了有毒噪声。文献中提出了不同的去噪技术来增强x射线图像。本文对x射线图像中噪声的提取进行了比较研究。对双边滤波、对偶树复小波变换、高斯滤波、维纳滤波和非局部均值滤波进行了比较,并利用NHANES-II数据库中的宫颈x射线图像对这些技术进行了评价。使用不同的性能指标对每种技术的重要性进行了评估。

Morphological operations and re-projection based novel low-dose CT reconstruction scheme 基于形态学操作和重投影的新型低剂量CT重建方案
Umar Talha, Tariq Mairaj, Waleed Bin Yousuf, Omer Zia
Computed Tomography (CT) has been a major contributor in revolutionizing and commercializing the medical imaging industry. However, it does so with some significant drawbacks. Most of the commonly used CT reconstruction algorithms need heavy dose of hazardous X-ray radiations. Higher X-ray dose produces better reconstructed image resolution, whereas low radiation dose projection data induces artifacts in the reconstructed image. It also reduces the image quality of conventional CT reconstruction algorithms [1]. The paper presents a novel algorithm for efficient CT reconstruction from low radiation dose projection data. In the proposed method, the phantom is subjected to low X-ray dose and then the projection data is enhanced using a series of post-processing algorithms and a new interpolation technique. The proposed algorithm is supported by computer simulation and promising results were observed. The proposed algorithm reduces the radiation dose to great extent, with good quality reconstructed image.
计算机断层扫描(CT)在医学成像行业的革命和商业化方面做出了重大贡献。然而,这样做有一些明显的缺点。大多数常用的CT重建算法都需要大剂量的有害x射线辐射。较高的x射线剂量产生较好的重建图像分辨率,而低辐射剂量投影数据在重建图像中产生伪影。它还降低了传统CT重建算法的图像质量[1]。提出了一种基于低辐射剂量投影数据的高效CT重建算法。在该方法中,先对体体进行低剂量x射线照射,然后采用一系列后处理算法和一种新的插值技术对投影数据进行增强。该算法得到了计算机仿真的支持,并取得了令人满意的结果。该算法在很大程度上降低了辐射剂量,获得了高质量的重建图像。

Adaptive processing of image using DWT and FFT OFDM in AWGN and Rayleigh channel 在AWGN和瑞利信道中采用DWT和FFT OFDM自适应处理图像
A. Mannan, A. Habib
Wireless communication has a very important role in the day to day life for everyone. The wireless technology is growing rapidly and there is a growing demand of high performance, capacity and larger bit rate wireless communication systems which cope wireless communication services such as high speed data, video and voice signals. Multicarrier modulation scheme like OFDM provides an efficient solution to overcome this problem. In this paper a gray scale image processing is done using a LMS algorithm with wavelet based OFDM system using the QPSK modulation scheme in AWGN and Rayleigh channel in SISO environment and results are compared with the conventional adaptive FFT based OFDM system. We reconstruct our transmitted signal at receiver; in both systems by minimizing the error by adaptive filter but the computational complexity of FFT based system is more as compared to DWT based system. Results are compared in term of SNR vs BER which shows that adaptive DWT based OFDM system perform better as compared to the conventional adaptive FFT OFDM system.

Cross gender voice morphing using Canonical Correlation Analysis 基于典型相关分析的跨性别语音变形
I. Baseer, Rabeea Basir
Voice morphing one of the speech synthesis frameworks, in simplest term aim to transforms speaker's identity from source to target speaker while preserving the original content of message. This paper presents a novel spectral envelope mapping algorithm based on Canonical Correlation Analysis(CCA) that find the association between spectral envelope characteristics of source speaker and target speaker in terms of correlation as a similarity metric. Moreover, the speech also undergoes to prosodic modification using PSOLA as pitch frequency is also an important parameter for varying identity. This morphing algorithm is evaluated by taking the utterances from freely available CMU-ARCTIC speech dataset. The subjective experiment shows that the proposed method successfully transforms speaker identity and produced high-quality morphed signal.
语音变形是语音合成框架中的一种,简单来说就是在保留原信息内容的前提下,将说话人的身份从源信息转换为目标信息。本文提出了一种基于典型相关分析(CCA)的频谱包络映射算法,该算法将源扬声器和目标扬声器的频谱包络特征之间的相关性作为相似度度量。此外,由于音调频率也是同一性变化的一个重要参数,语音也会通过PSOLA进行韵律修饰。该变形算法通过从免费的CMU-ARCTIC语音数据集中提取语音来评估。主观实验表明,该方法成功地变换了说话人身份,产生了高质量的变形信号。

Quantification of PIR protocols privacy PIR协议隐私的量化
R. Khan, Mohibullah, Muhammad Arshad Islam
In current era the best way to find the information over the internet is search engine. Web search engines maintains user profile for better search results which could raise serious privacy issues. In order to intact the users privacy in front of a web search engines Private information retrieval (PIR) protocols are used which hide the identity of the user by submitting his/her query through other group member. A basic problem is related with these protocols are their predictability. This paper is the extension of previous work in which a person with anonymous query was successfully identified. This paper aims to find all queries submitted by the target user using UPIR and UUP protocols. For experimentation purpose a machine learning based adversarial model is proposed to find the actual queries of user of interest based on the previous profile. The results shows that the precision, recall and f-measure of J48 in finding user's real queries is more then 0.70 on the average. Similarly J48 reported highest trues positive rate of above 0.7 and lowest false positive rate of 0.006. It was also observed that the size of training data has very little effect on accuracy according to this experiment.
在当今时代,在互联网上找到信息的最好方式是搜索引擎。网络搜索引擎维护用户档案以获得更好的搜索结果,这可能会引发严重的隐私问题。为了在网络搜索引擎面前保护用户的隐私,使用了隐私信息检索(PIR)协议,该协议通过其他组成员提交用户的查询来隐藏用户的身份。与这些协议相关的一个基本问题是它们的可预测性。本文是对先前成功识别具有匿名查询的人的工作的扩展。本文旨在查找使用UPIR和UUP协议的目标用户提交的所有查询。为了实验目的,提出了一种基于机器学习的对抗模型,以基于先前的配置文件找到感兴趣的用户的实际查询。结果表明,J48搜索用户真实查询的准确率、查全率和f-measure平均值均在0.70以上。同样,J48的真阳性率最高为0.7以上,假阳性率最低为0.006。我们还观察到,根据本实验,训练数据的大小对准确率的影响很小。

Distributed teams faced a lot of obstacles faced while applying Agile practices in distributed environment, these obstacles were poorly understood by local software industry. In market, Agile and distributed software development became a need more than a trend. It seems to be problematic when Agile and distributed software development merge. There is need to identify those Agile practices adoptable for distributed teams and can also help local software industry to produce a quality software. This study contributes an empirical based investigation of the critical factors affect in Agile distributed. Study inductively formulated a theoretical model of how specific agile alignment practices affect in mitigating distributed Agile software development process. The model presented in this paper presented state-of-the-art of critical factors affect in Distributed Agile environment given in literature. For further proof of concept a case study was conducted to test the applicability of proposed model in local environment. Results indicate basis for further research in local industry Proposed model makes applicability of agile practices in distributed environment by tailoring Scrum and XP methods.
分布式团队在分布式环境中应用敏捷实践时面临着许多障碍,而这些障碍却很少被本地软件行业所理解。在市场上,敏捷和分布式软件开发已经成为一种需求,而不是一种趋势。当敏捷和分布式软件开发合并时,似乎会出现问题。有必要确定那些适合分布式团队的敏捷实践,也可以帮助本地软件行业生产高质量的软件。本研究对影响敏捷分布式开发的关键因素进行了实证研究。研究归纳地建立了一个理论模型,说明具体的敏捷对齐实践如何影响分布式敏捷软件开发过程。本文所建立的模型反映了文献中影响分布式敏捷环境的关键因素的现状。为了进一步证明概念,进行了案例研究,以测试所提出的模型在当地环境中的适用性。该模型通过对Scrum和XP方法的裁剪,使敏捷实践在分布式环境中具有适用性。
