Complete Component-Wise Software Certification for Safety-Critical Embedded Devices 安全关键嵌入式设备的完整组件智能软件认证
Detlef Streitferdt, A. Zimmermann, Jörg Schaffner, Michael Kallenbach
Safety certification became an increasingly important issue as well as a feature of industrial software development. The certification process for safe software causes enormous efforts and has to be repeatedly executed for any changes in the systems. Modular and component-based software architectures are very common, but cannot use their advantages in the certification process. This paper presents the results of an industrial software development and certification project in the railway domain and enhances a previous work to change components without a re-certification by additional requirements, which have to be met, to allow for changes in the basic framework of the system as well, again, without re-certification.
安全认证已成为一个日益重要的问题,也是工业软件开发的一个特点。安全软件的认证过程需要付出巨大的努力,并且必须反复执行系统中的任何更改。模块化和基于组件的软件体系结构非常常见,但在认证过程中无法发挥其优势。本文介绍了铁路领域的一个工业软件开发和认证项目的结果,并通过必须满足的额外需求来改进以前的工作,以更改组件而无需重新认证,从而允许更改系统的基本框架,同样,无需重新认证。

Detection of continuous and thin edges of noisy images by new kernel approach 基于新核方法的噪声图像连续边缘和细边缘检测
Tauseef Ahmad, Amr Almaddah
In image processing, edge detection concerns with the localization of discontinuity of the gray scale images, accurately detecting continuous edges is difficult in noisy images. Usually for accurate edge detection requires smoothing and differentiation, to localize edge pixels in intensity images. Smoothing images with median filter instead of Gaussian filter has more edge preserving tendency. In this proposed method, filtered images with non- linear filter, which is convolved with two new developed 3x3 operators for detecting gradient magnitude of images. The resulted thick binary edges were filter with two new developed structure matrices for enhancement in binary edges. The new algorithm is examined and compared with the traditional edge detectors. The comparison is based on two type of distributed noises Gaussian and salt and pepper. The results comparison suggests that the new algorithm detect edges more accurate thinner and smoother than the edges detected by traditional edge detector.
在图像处理中,边缘检测涉及到灰度图像不连续点的定位,在噪声图像中很难准确检测到连续边缘。通常为了进行精确的边缘检测,需要对强度图像进行平滑和微分,以定位边缘像素。用中值滤波代替高斯滤波平滑图像,具有更强的边缘保持倾向。在该方法中,利用非线性滤波器对图像进行滤波,并与两种新开发的用于检测图像梯度大小的3x3算子进行卷积。用两种新开发的结构矩阵对得到的粗二值边缘进行滤波,增强二值边缘。对新算法进行了检验,并与传统边缘检测器进行了比较。比较是基于两种类型的分布噪声高斯和盐胡椒。结果表明,与传统边缘检测器检测的边缘相比,新算法检测的边缘更精确、更薄、更平滑。

Link Quality Driven Hybrid Scheme for Multi-hop Message Broadcast in VANETs vanet中链路质量驱动的多跳消息广播混合方案
O. Rehman, M. Ould-Khaoua
A radical transformation is foreseen in the automotive industry for which Vehicular Ad hoc NETworks (VANETs) is a major attraction. This is due to its potential to support a wide range of applications that can lead towards new driving and travelling experiences. Multi-hop broadcasting approach is expected to be the primary mode of communication among vehicles. Suitable choice of the next-hop relay nodes is an essential part for the design of multi-hop messaging schemes in VANETs. This greatly impacts the reception of the broadcasted messages, particularly when evaluated on high node density networks. This research proposes a link quality driven hybrid scheme that attempts to systematically combine multiple link quality based message dissemination schemes in a particular order. The proposed scheme attempts to improve message reception performance over stringent communication conditions. Our performance evaluation indicates that the suggested scheme improves messages reception over high node density networks compared to the existing conventional versions.
汽车自组织网络(VANETs)是汽车行业的主要吸引力,预计汽车行业将发生根本性的转变。这是因为它有潜力支持广泛的应用,可以带来新的驾驶和旅行体验。预计多跳广播方法将成为车辆间通信的主要模式。下一跳中继节点的合理选择是vanet中多跳消息传递方案设计的关键。这极大地影响了广播消息的接收,特别是在高节点密度网络上进行评估时。本研究提出了一种链路质量驱动的混合方案,该方案尝试以特定顺序系统地组合多个基于链路质量的消息传播方案。该方案试图在严格的通信条件下提高消息接收性能。我们的性能评估表明,与现有的传统版本相比,建议的方案改善了高节点密度网络上的消息接收。

Current State of Cloud-Based E-learning Adoption: Results from Gulf Cooperation Council's Higher Education Institutions 基于云的电子学习采用现状:来自海湾合作委员会高等教育机构的结果
Qasim Alajmi, Ruzaini bin Abdullah Arshah, Adzhar Kamaludin, Mohammed A. Al-Sharafi
Many Higher Education Institutions are shifting to Cloud-Based E-Iearning (CBEL) due to its benefits. These benefits include reduced costs of accessing IT services, pooling of resources, scalability, and mobility as well as consumer satisfaction among others. However, some institutions especially in developing countries in general and Gulf Cooperation Council (GCC) in particular still reluctant to adopt CBEL due to many factors. There is necessity to find out the factors that drive the adoption of CBEL in higher education institutions. This study was carried out to find out the factors that determine whether these institutions in GCC would adopt the CBEL or not. The study involved a group of respondents from the GCC who provided with an On-line survey sent to identify the factors they thought played a role in determining whether institutions would adopt the CBEL or not. The base for this study was TOE and DOI adoption theories. The following factors were recommended by researchers; Technological Factors such as Relative advantage, Complexity, Compatibility which derived from DOI theory and Organizational factors such as Fit, Decision maker, Cost reduction, and IT readiness which derived from TOE framework, and Information culture behavioral such as Information Integrity, Information Formality, Information Control and Information Pro-activeness which derived from Information culture factors.
由于其优势,许多高等教育机构正在转向基于云的电子学习(CBEL)。这些好处包括降低访问IT服务的成本、资源池、可伸缩性和移动性以及消费者满意度等。然而,由于许多因素,一些机构,特别是发展中国家的机构,特别是海湾合作委员会的机构,仍然不愿意采用CBEL。有必要找出推动高等院校采用CBEL的因素。本研究的目的是找出决定GCC国家这些机构是否采用CBEL的因素。该研究涉及一组来自海湾合作委员会的受访者,他们提供了一份在线调查,以确定他们认为在决定机构是否采用CBEL方面发挥作用的因素。本研究的基础是TOE和DOI采用理论。研究人员推荐了以下因素:技术因素如DOI理论衍生的相对优势、复杂性、兼容性,组织因素如TOE框架衍生的契合度、决策者、成本降低、IT就绪度,信息文化行为因素如信息完整性、信息正式性、信息控制和信息主动性。

Improved Epilepsy Detection method by addressing Class Imbalance Problem 针对类不平衡问题改进癫痫检测方法
Siddhartha Haldar, R. Mukherjee, Pushpak Chakraborty, Shayan Banerjee, Shreyaasha Chaudhury, Sankhadeen Chatterjee
Early and reliable detection of neurological disorders is important for effective treatment of patients. In spite of reasonable amount of research done in the field of early detection of epileptic seizure, still an effective model for predicting the same is absent. Motivated by this, in the current study the class imbalance problem associated with classification of patients into healthy and epilepsy affected ones is addressed. Two well established algorithms namely Synthetic Minority Oversampling Technique (SMOTE) and Selective Pre-Processing of Imbalanced Data Algorithm (SPIDER) have been used in order to combat the imbalanced classes. Afterwards, three different classifiers namely KNN, SVM and MLP-FFN have been used for the classification task. Experimental results revealed that addressing imbalances classes improved the classification accuracy to a greater extent.
神经系统疾病的早期可靠检测对于有效治疗患者非常重要。尽管在癫痫发作的早期检测领域做了大量的研究,但仍然缺乏一个有效的预测模型。基于此,本研究解决了将患者分为健康患者和癫痫患者的类不平衡问题。两种成熟的算法,即合成少数过采样技术(SMOTE)和选择性预处理不平衡数据算法(SPIDER)被用于对抗不平衡类。然后,使用KNN、SVM和MLP-FFN三种不同的分类器进行分类任务。实验结果表明,处理不平衡类可以在很大程度上提高分类精度。

M. Jamshidi, N. Alibeigi, Nahid Rabbani, Bahareh Oryani, A. Lalbakhsh
Recently, using the statistical methods for analysis of humans' relationships has experienced a dramatic growth by psychologists. Although, surveying such complex concepts is considered as a difficult calculation by mathematical or statistical methods, computational intelligence-based approaches are able to examine any kinds of complex functions. In this paper, a practical approach based on Artificial Neural Networks (ANN) as a helpful tool to analyze data in the field of cognitive psychology is demonstrated. To illustrate the proposed method, a psychology problem based on 5 questionnaires was designed and each of questionnaires was filled randomly by MATLAB. The errors of the network are shown by surface function, verifying the reliability of the proposed method.

An Interactive Framework to Allocate and Manage Teaching Workload using Hybrid OLAP Cubes 使用混合OLAP多维数据集分配和管理教学工作量的交互式框架
W. Haque
Assignment of teaching workload is an essential annual ritual in all academic institutions. Depending upon the structure and complexity, it can be a painful process for department heads and administrative deans who are responsible for resource allocation. We present a framework which uses business intelligence techniques to allow asynchronous data entry, analysis and reporting in a collaborative environment to assist with the decision-making process. To begin, the first-tier administrators make workload assignments in consultation with faculty using interactive web forms, data is pushed to the underlying database or cube, reports are rendered, and memos are auto-generated. Deans responsible for approval are able to review the information along several dimensions and make informed decisions regarding the assignments. Historical data remains available for future years for trends and analysis. Besides achieving the benefits from transparency of the process, the framework exploits both OLAP cubes and relational data stores for optimum performance.
教学工作量分配是所有学术机构必不可少的年度仪式。根据结构和复杂程度的不同,对于负责资源分配的部门主管和行政院长来说,这可能是一个痛苦的过程。我们提出了一个框架,该框架使用商业智能技术在协作环境中允许异步数据输入、分析和报告,以协助决策过程。首先,第一层管理员使用交互式web表单与教员协商完成工作负载分配,将数据推送到底层数据库或多维数据集,呈现报告,并自动生成备忘录。负责审批的院长能够从几个方面审查信息,并就任务做出明智的决定。历史数据仍可用于未来几年的趋势和分析。除了从流程透明性中获益之外,该框架还利用OLAP多维数据集和关系数据存储来实现最佳性能。

Analysing Feature Importances for Diabetes Prediction using Machine Learning 利用机器学习分析糖尿病预测的特征重要性
Debadri Dutta, Debpriyo Paul, Partha Ghosh
Diabetes is an uprising illness, particularly because of the kind of nourishment we are having these days and the conflicting eating regimen and schedule that we take after. Diabetes are fundamentally caused because of obesity or high glucose level, and so forth. So in this paper we will discover what are the critical elements for the reason for diabetes. Variable and feature choice have turned into the focal point of much research in regions of utilization for which datasets with tens or a huge number of factors are accessible. Likewise we will center around the most essential features to predict whether a person will have chances to develop diabetes in the future.
糖尿病是一种突发疾病,特别是因为我们现在所吃的那种营养以及我们所遵循的相互冲突的饮食方案和时间表。糖尿病的根本原因是肥胖或高血糖等等。所以在这篇论文中,我们将发现什么是导致糖尿病的关键因素。变量和特征的选择已经成为许多研究的焦点,在利用领域,有几十个或大量因素的数据集是可访问的。同样,我们将围绕最基本的特征来预测一个人将来是否有机会患糖尿病。

Bikramjit Dasgupta, Damian Valles, S. McClellan
This paper shows that with bandwidth and round-trip time statistics, data analytics can be used to classify three characteristic phenomena in wireless signal use: decreases in bandwidth due to signal over-saturation, signal attenuation due to increasing distance, and signal improvement due to decreasing distance. Using a K-Means algorithm, bandwidth and round-trip time trends were clustered correctly by signal loss type with a 99.98% accuracy rating with 10,000 validation samples.
本文表明,通过带宽和往返时间统计,数据分析可以对无线信号使用中的三种特征现象进行分类:信号过饱和导致的带宽减少,距离增加导致的信号衰减,距离减少导致的信号改善。使用K-Means算法,在10000个验证样本中,带宽和往返时间趋势按信号损失类型正确聚类,准确率达到99.98%。

Using a K-Means algorithm, bandwidth and round-trip time trends were clustered correctly by signal loss type with a 99.98% accuracy rating with 10,000 validation samples.","PeriodicalId":368939,"journal":{"name":"2018 IEEE 9th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON)","volume":"390 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133863672","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}
