Cancer is a term used for a disease in which abnormal cells divide without control and are able to invade other tissues. Obesity is an overnutrition disease that is associated with increased risks of many types of cancers. The knowledge of this medical domain is highly required to be represented with its concepts, properties and types of association using ontologies to provide the biomedical community with consistent, reusable and sustainable descriptions of human obesity related cancer terms. In this paper, we propose building Obesity Related Cancer (ORC) Ontology involving diseases, symptoms, diagnosis, and treatment, using the latest standard Web Ontology language (OWL 2). The diseases hierarchy and terms are defined upon the standard Disease Ontology (DO). By developing (ORC) Ontology, both intelligent systems and physicians can benefit from it in knowledge sharing, reasoning and reusing in different ways.
癌症是一种疾病的术语,其中异常细胞不受控制地分裂,并能够侵入其他组织。肥胖是一种营养过剩的疾病,与多种癌症的风险增加有关。这一医学领域的知识非常需要用本体来表示其概念、属性和关联类型,以便为生物医学界提供一致的、可重复使用的和可持续的人类肥胖相关癌症术语描述。本文提出使用最新的标准Web Ontology语言(OWL 2)构建肥胖症相关癌症(Obesity Related Cancer, ORC)本体,包括疾病、症状、诊断和治疗。疾病层次和术语在标准疾病本体(Disease Ontology, DO)上定义。通过开发(ORC)本体,智能系统和医生都可以以不同的方式从知识共享、推理和重用中受益。

As a common software engineering practice, software dynamic defect models are used to estimate and predict the software testing process progress, effectiveness, and the number of future defects over the next weeks. Practitioners use these dynamic defect models to ensure that the delivery of software to customers is possible from the quality point of view and to predict the release date. Old literature suggested several classic defect models including Putnam, Exponential, Rayleigh and Weibull. Recent literature claimed that modern projects follow linear combinations of Rayleigh due to projects complexity. This claim verification has not been generalized because the project samples size was very small. This paper proposes a tool suite for dynamic defect models. The tool suite consists of an open repository of dynamic defects empirical data and many supporting tools. Data concerning defects are collected from several software projects and products and added to the open repository. This includes open source software and commercial software projects. The proposed tools are designed and implemented and made publicly available on the web. They are used to view the dynamic defects, find the best dynamic defect model that fits the data according to several performance criteria and predict future number of defects. The application of these tools on the empirical data showed that linear combinations of Rayleigh and Weibull has better performance than classic models in both curve fitting and predictability of commercial software.
作为一种常见的软件工程实践,软件动态缺陷模型用于估计和预测软件测试过程的进度、有效性,以及未来几周的缺陷数量。从业者使用这些动态缺陷模型来确保从质量的角度来看软件交付给客户是可能的,并预测发布日期。旧文献提出了几种经典的缺陷模型,包括Putnam, Exponential, Rayleigh和Weibull。最近的文献声称,由于项目的复杂性,现代项目遵循Rayleigh的线性组合。由于该项目样本量非常小,因此该索赔验证尚未普遍化。本文提出了一个用于动态缺陷模型的工具套件。该工具套件由一个开放的动态缺陷经验数据存储库和许多支持工具组成。有关缺陷的数据从几个软件项目和产品中收集,并添加到开放的存储库中。这包括开源软件和商业软件项目。建议的工具被设计和实现,并在网络上公开提供。它们被用来观察动态缺陷,根据几个性能标准找到最适合数据的动态缺陷模型,并预测未来缺陷的数量。这些工具在实证数据上的应用表明,Rayleigh和Weibull的线性组合在曲线拟合和商业软件的可预测性方面都优于经典模型。

Sign Language (SL) recognition has been explored for a long time now. Two main aspects of successful SL recognition systems are required: High recognition accuracy and real-time response. This paper shows a contribution in these issues, the first contribution describes a real-time response recognition for Arabic Sign Language (ArSL) based on a Graphics Processing Unit (GPU) implantation. The second contribution exploits Multi-level Multiplicative Neural Network(MMNN) for hand gesture classification. The system architecture mainly depends on two consequent layers of (MMNN), the first layer determines if the signer uses one hand or two hands and the second determines the final class. The experiment was conducted on 200signs and the resultreaches83% recognition accuracy for test data confirming objects dataset offline extendibility. The recognition system is being accelerated using NVIDIA GPU and programming in CUDA.

Most Named Entity Recognition (NER) systems follow either a rule-based approach or machine learning approach. In this paper, we introduce out attempt at developing a hybrid NER system, which combines the rule-based approach with a machine learning approach in order to obtain the advantages of both approaches and overcomes their problems [1]. The system is able to recognize eight types of named entities including Location, Person, Organization, Date, Time, Price, Measurement and Percent. Experimental results on ANERcorp dataset indicated that our hybrid approach outperforms the rule-based approach and the machine learning approach when they are processed separately. Moreover, our hybrid approach outperforms the state-of-the-art of Arabic NER.

The development of broad range of multi-core processors in desktop and server systems has lead to a definite need of an overall performance evaluation tool. This paper presents a new tool to analyze the performance of multi-core systems at early design phases. The proposed tool helps developers test different design options and choose the best solution for multi-core applications. Different design factors can be considered and evaluated to get the best core utilization of multi-core systems while achieving the best response time for the real-time applications. The paper explores the implementation of different algorithms at four different design stages: dependability analysis, task execution sequence, real-time scheduling and core mapping. As a proof of concept, a case study is presented to show the significance of changing one design parameter on the overall system performance. Experimental results show an increase of the CPU utilization by 31.25% when changing the number of cores from 3 to 2.

This article presents an automatic classification approach for assessing water quality based on fish liver histopathology. As fish liver is a good bioindicator for detecting water chemical pollution, the proposed approach utilizes fish liver microscopic images in order to detect water pollution. The proposed approach consists of three phases; namely pre-processing, feature extraction, and classification phases. Since color and texture are the most important characteristics of microscopic fish liver images, the proposed system uses colored histogram and Gabor wavelet transform for classifying water quality degree. Also, it implemented Principal Components Analysis (PCA) along with Support Vector Machines (SVMs) algorithms for feature extraction and water quality degree classification, respectively. Collected datasets contain colored JPEG images of 125 images as training dataset and 45 images as testing dataset, respectively. Training dataset is divided into 4 classes representing the different histopathlogical changes and their corresponding water quality degrees. Experimental results showed that the proposed classification approach has obtained water quality classification accuracy of 93.3%, using SVMs linear kernel function with 37 images per class for training.
本文提出了一种基于鱼肝组织病理学的水质自动分类方法。由于鱼肝脏是检测水体化学污染的良好生物指标,本方法利用鱼肝脏显微图像检测水体污染。拟议的办法包括三个阶段;即预处理、特征提取和分类三个阶段。由于颜色和纹理是微观鱼肝图像最重要的特征,该系统采用彩色直方图和Gabor小波变换对水质程度进行分类。同时,将主成分分析(PCA)和支持向量机(svm)算法分别用于特征提取和水质程度分类。收集的数据集分别包含125张彩色JPEG图像作为训练数据集和45张图像作为测试数据集。训练数据集分为4类,代表不同的组织病理变化及其对应的水质程度。实验结果表明,采用支持向量机线性核函数对每类37张图像进行训练,所提出的分类方法获得了93.3%的水质分类准确率。

Aquatic weeds are the greatest generator of biomass in aquatic environment which motivates using intelligent methods for the prediction and estimation of indicators that affect the growth of such weeds. In this study a set of new interpolation methods are used and assessed over the study area for predicting a set of chemical indicators that can predict and affect the growth of weeds. The used methods are bi-harmonic, regularized spline with tension, Barnes, tri-scatter, and kriging. The different interpolants are used to create thematic maps representing the different chemical indicators that are sensed at discrete positions for supporting decision making. The performance of individual interpolants is assessed using mean square error over a set of test sites. Results prove that the Tri-scatter interpolant is the one with best performance for all the sensed indicators while the regularized spline performs well when the number of points for interpolation is large enough.
水生杂草是水生环境中最大的生物量产生者,这促使人们使用智能方法来预测和估计影响水生杂草生长的指标。本研究采用了一套新的插值方法,并在研究区进行了评估,以预测一套能够预测和影响杂草生长的化学指标。使用的方法有双谐波、张力正则样条、巴恩斯、三散射和克里格。不同的插值器用于创建代表不同化学指标的专题地图,这些指标在离散位置被感知,以支持决策。使用一组测试点的均方误差来评估单个内插器的性能。结果表明,三散点插值法对所有感测指标的插值效果最好,而正则样条插值法在插值点数足够大时表现较好。

Image mosaicing/stitching is considered as an active research area in computer vision and computer graphics. Image mosaicing is concerned with combining two or more images of the same scene into one panoramic image with high resolution. There are two main types of techniques used for creating image stitching: direct methods and feature-based methods. The greatest advantages of feature-based methods over the other methods are their speed, robustness, and the availability of creating panoramic image of a non-planar scene with unrestricted camera motion. In this paper, we propose a real time image stitching system based on ORB feature-based technique. We compared the performance of our proposed system with SIFT and SURF feature-based techniques. The experiment results show that the ORB algorithm is the fastest, the highest performance, and it needs very low memory requirements. In addition, we make a comparison between different feature-based detectors. The experimental result shows that SIFT is a robust algorithm but it takes more time for computations. MSER and FAST techniques have better performance with respect to speed and accuracy.
图像拼接是计算机视觉和计算机图形学领域的一个活跃研究领域。图像拼接是将同一场景的两幅或多幅图像组合成一幅高分辨率的全景图像。有两种主要类型的技术用于创建图像拼接:直接方法和基于特征的方法。与其他方法相比,基于特征的方法的最大优点是速度快,鲁棒性好,并且可以在相机运动不受限制的情况下创建非平面场景的全景图像。本文提出了一种基于ORB特征技术的实时图像拼接系统。我们将所提出的系统的性能与SIFT和SURF基于特征的技术进行了比较。实验结果表明,ORB算法速度最快,性能最高,并且对内存的要求非常低。此外,我们对不同的基于特征的检测器进行了比较。实验结果表明,SIFT算法具有较好的鲁棒性,但计算量较大。MSER和FAST技术在速度和精度方面具有更好的性能。

An overview on non-parametric spectrum sensing in cognitive radio 认知无线电中的非参数频谱感知技术综述

The scarcity of frequency spectrum used for wireless communication systems has attracted a considerable amount of attention in recent years. The cognitive radio (CR) terminology has been widely accepted as a smart platform mainly aimed at the efficient interrogation and utilization of permitted spectrum. Non-parametric spectrum sensing, or estimation, represents one of the prominent tools that can be proposed when CR works under an undetermined environment. As such, the periodogram, filter bank, and multi-taper methods are well considered in many studies without relying on the transmission channel's characteristics.

近年来,用于无线通信系统的频谱的稀缺性引起了相当多的关注。认知无线电(cognitive radio, CR)术语作为一种智能平台已被广泛接受,其主要目的是有效地询问和利用允许的频谱。非参数频谱感知或估计是CR在不确定环境下工作时可以提出的重要工具之一。因此,在不依赖于传输信道特性的情况下,周期图、滤波器组和多锥度方法在许多研究中得到了很好的考虑。本文对所有这些非参数频谱传感技术提出了统一的方法,并用仿真方法进行了分析和性能比较。结果表明,多锥度法优于其他方法。

Non-parametric spectrum sensing, or estimation, represents one of the prominent tools that can be proposed when CR works under an undetermined environment.

After the evolution of Java-based smart cards, security issues arises concerning Java applets not to be vulnerable to modifications or malicious attacks that may threaten applications supported by these applets. Bytecode verification fills the latter gap. Java Sandbox Security model and Common Criteria standard suggest on-board bytecode verification to maximize security. This paper suggests an on-card bytecode verification whose execution is distributed within Java applet's lifecycle. Part of the verification runs on-demand at the run-time execution phase of the Java applets. The proposed solution targets a real Java-based card operating system.
在以Java为基础的智能卡发展之后,有关Java小程序的安全问题出现了,这些小程序必须不易受到修改或恶意攻击,以免威胁到由这些小程序所支援的应用程序。字节码验证填补了后者的空白。Java沙盒安全模型和通用标准建议板载字节码验证,以最大限度地提高安全性。本文提出了一种卡上字节码验证,其执行分布在Java applet的生命周期内。部分验证在Java小程序的运行时执行阶段按需运行。提出的解决方案的目标是一个真正的基于java的卡片操作系统。
