Robust Full-Car Active Suspension System 坚固的全车主动悬架系统
Y. M. Al-Rawashdeh, S. E. Ferik, M. A. Abido
In this paper, a robust full-car active suspension system is designed. All parameters involved, except those related to the chassis of the car, are considered uncertain and the center of gravity position is assumed to be fixed. The resulting uncertain system constitutes of many uncertain parameters and the robust problem is found to be non-convex. Particle Swarm Optimization technique is devised to solve this problem resulting in an iterative PSO/LMI optimization algorithm. SimMechanics is used to build the nonlinear full-car model and to allow future extensions such that complex cases can be considered, i.e., the passengers, goods, or the like might be uncertain or having their own dynamics onboard.
本文设计了一种鲁棒的整车主动悬架系统。除了与汽车底盘有关的参数外,所涉及的所有参数都被认为是不确定的,并且假定重心位置是固定的。得到的不确定系统由许多不确定参数组成,鲁棒性问题是非凸的。为了解决这一问题,提出了粒子群优化技术,得到了一种迭代的粒子群优化算法。SimMechanics用于建立非线性全车模型,并允许将来的扩展,以便考虑复杂的情况,即乘客,货物或类似的东西可能是不确定的或有自己的动态。

Lana Issa, Mahdi Alkhatib, Aalaa Al-badarneh, A. Qusef
In today’s contemporary world, one of the most significant challenges facing most organizations is the challenge of employee retention. To remain efficient in an extremely competitive world, it is important for organizations to invest in measures that enhance the productivity and motivation of their workforce. In essence, this is the key to remaining relevant. Agile project management is the newest trend in project management methods that support concepts of flexibility and continuous improvements which help to keep an organization’s workforce efficient and motivated and reflect positively on employee retention. In this theoretical paper, we aim to critically analyze how the various Agile methods support employee retention better than traditional approaches by matching employee retention’s best practices within its approach. In this work, we found that agile systems implicitly handle several job satisfaction factor and thus help with employee retention without extra effort done by human resource management in traditional approaches.
在当今世界,大多数组织面临的最重要的挑战之一是员工保留的挑战。为了在竞争激烈的世界中保持效率,组织投资于提高生产力和员工积极性的措施是很重要的。从本质上讲,这是保持相关性的关键。敏捷项目管理是项目管理方法的最新趋势,它支持灵活性和持续改进的概念,有助于保持组织的劳动力效率和积极性,并积极反映员工的保留。在这篇理论论文中,我们的目标是批判性地分析各种敏捷方法如何通过在其方法中匹配员工保留的最佳实践来比传统方法更好地支持员工保留。在这项工作中,我们发现敏捷系统隐含地处理了几个工作满意度因素,从而帮助员工保留,而无需传统方法中的人力资源管理额外的努力。

A No-Reference Image Quality Assessment For Detecting Illumination Alteration 一种检测光照变化的无参考图像质量评估方法
Cerine Tafran, Mohamad El-Abed, Islam Elkabani, Ziad Osman
The Quality assessment of a face image is a topic of great interest for biometric applications where images with bad samples decrease the system performance and increase authentication errors, especially in biometric passport applications that use only a single image for enrollment. Thus, in order to have a useful biometric authentication system, the quality of the biometric sample images must be controlled. This paper presents a no-reference quality assessment method which detects the illumination problem using Symmetric Based Features along with BLIINDS Based Features. The experimental results on the AR database recorded an accuracy of 90.3 % by using Stochastic Gradient Descent (SGD) classifier.
人脸图像的质量评估是生物识别应用非常感兴趣的一个主题,其中带有不良样本的图像会降低系统性能并增加身份验证错误,特别是在仅使用单个图像进行注册的生物识别护照应用中。因此,为了建立一个有用的生物识别认证系统,必须对生物识别样本图像的质量进行控制。本文提出了一种基于对称特征和盲点特征的无参考质量评价方法。在AR数据库上的实验结果表明,采用随机梯度下降(SGD)分类器进行分类的准确率达到90.3%。

Saif Rawashdeh, Walaa Eyadat, Areen Magableh, W. Mardini, M. B. Yasin
The smart world is an era in which things (e.g., cars, buses, computers, and mobile phones) can serve people in an effective and collaborative manner. Internet of Things (IoT) connects many devices with each other. IoT devises sense, gather, process, and transmit information from their surroundings. This transmission and exchange of a large amount of data between billions of devices cause massive consumption of energy. The central aim of Green IoT is reducing power consumption of IoT devices to create a safe and sustainable environment for IoT. In this paper, we presented an overview about IoT and the Green IoT, then classified the techniques of the Green IoT into three taxonomies that are Software Based Green IoT techniques, Hardware-Based Green IoT techniques and Policy Based Green IoT techniques. Finally, we compared many Green models, systems, and algorithms to improve and reduce the energy consumption of IoT devices.

Optimization of PID Controller Gain Using Evolutionary Algorithm and Swarm Intelligence 基于进化算法和群体智能的PID控制器增益优化
D. Maddi, A. Sheta, Dharani Davineni, Heba Al-Hiary
Design of the Proportional-Integral-Derivative (PID) controller for an industrial process represents a challenge due to process complexity and non-linearity. Traditional methods such as Ziegler-Nichols (ZN) for PID controller tuning do not provide an optimal gain; thus, might leave the system with potential instability condition and cause significant losses and damages to the system. This paper investigates the merits of evolutionary and swarm-based optimization algorithms in fine-tuning the parameters of a PID controller. Here, Genetic Algorithms (GAs) and Particle Swarm Optimization (PSO) algorithm were utilized to optimize the PID controller for a DC motor system. Various fitness functions were provided for the presented algorithms to compute the performance of the controller. A new fitness function was proposed to achieve an outstanding control response for the DC motor system. Results demonstrate the efficacy of the proposed methods in improving closed loop system response.
由于过程的复杂性和非线性,工业过程的比例-积分-导数(PID)控制器的设计是一个挑战。传统的方法,如Ziegler-Nichols (ZN) PID控制器调谐不能提供最优增益;因此,可能使系统处于潜在的不稳定状态,并对系统造成重大损失和损害。本文研究了进化优化算法和基于群的优化算法在PID控制器参数微调中的优点。本文采用遗传算法(GAs)和粒子群算法(PSO)对直流电机系统的PID控制器进行优化。为所提出的算法提供了各种适应度函数来计算控制器的性能。提出了一种新的适应度函数,使直流电动机系统具有良好的控制响应。结果证明了所提方法在改善闭环系统响应方面的有效性。

Arabic Handwritten Characters Recognition using Convolutional Neural Network 用卷积神经网络识别阿拉伯手写体字符
Hassan M. Najadat, Ahmad A. Alshboul, Abdullah Alabed
Recognition of Arabic handwritten characters is very important due to its various benefits and usages. Ancient documents, bank processing, postal mailing and others are examples where we may need character recognition systems. But many obstacles may be faced due to diversity of human writing styles. Language characters recognition has been widely covered in many languages and many algorithms and paradigms were used. With the strong appealing of deep CNN classifier promise results were reached in many classification problems. CNN is a feed forward neural network that is extensively used in several applications such as image classification. The main benefit of using CNN is the merging of feature extraction and classification itself. Some researchers used CNN in Arabic character recognition, one of those El-Sawy et al [1] who applied CNN architecture on a dataset namely (AHCD) of 16800 characters. They obtained a good accuracy of 94.9% and a misclassification error of 5.1% on testing data. In our paper we will explore their dataset by proposing a modified CNN architecture hopefully to overcome their results.
由于阿拉伯手写字符的各种优点和用途,识别它是非常重要的。古代文件、银行处理、邮政邮件等都是我们可能需要字符识别系统的例子。但由于人类写作风格的多样性,可能会面临许多障碍。语言字符识别在许多语言中都有广泛的涉及,并且使用了许多算法和范式。由于深度CNN分类器的强大吸引力,在许多分类问题上都取得了令人满意的结果。CNN是一种前馈神经网络,广泛应用于图像分类等多个领域。使用CNN的主要好处是融合了特征提取和分类本身。一些研究人员将CNN用于阿拉伯字符识别,其中El-Sawy等[1]将CNN架构应用于16800个字符的数据集(AHCD)。对测试数据的分类准确率为94.9%,误分类误差为5.1%。在我们的论文中,我们将通过提出一种改进的CNN架构来探索他们的数据集,希望能克服他们的结果。

Qasem Abu Al-Haija, L. Tawalbeh
Recently, cybercrimes are causing huge impact on different cyber systems that might include vital information such as financial transactions and medical records. A better understanding of the accelerating numbers of cybercrimes and their enormous cost could help the global in bridging the gap between their defenses and the escalating numbers cyber criminals. In this paper, we present an estimation model of cybercrimes time series using auto-regressive (AR) model by employing the optimal modeling order that maximizes the estimation accuracy while maintaining minimum prediction error. The proposed model was developed using Matlab to estimate the time series for yearly global number of cybersecurity incidents activity during the period from 2009-2018 and forecast the figures for next upcoming years 2019-2020. The simulation results showed that the optimal model order to estimate the given cybercrime activity is AR(4) since its corresponds to minimum acceptable predication error values to estimate the signal recording an estimation accuracy of 93.5%.
最近,网络犯罪对不同的网络系统造成了巨大的影响,这些系统可能包括金融交易和医疗记录等重要信息。更好地了解不断增加的网络犯罪数量及其巨大的成本,可以帮助全球弥合他们的防御与不断增加的网络犯罪之间的差距。在本文中,我们提出了一种基于自回归(AR)模型的网络犯罪时间序列估计模型,该模型采用了在保持最小预测误差的同时使估计精度最大化的最优建模顺序。该模型使用Matlab开发,用于估计2009-2018年全球网络安全事件活动年度数量的时间序列,并预测2019-2020年的数据。仿真结果表明,估计给定网络犯罪活动的最优模型阶数为AR(4),因为它对应于估计信号记录的最小可接受预测误差值,估计精度为93.5%。

In this paper, we present an estimation model of cybercrimes time series using auto-regressive (AR) model by employing the optimal modeling order that maximizes the estimation accuracy while maintaining minimum prediction error. The proposed model was developed using Matlab to estimate the time series for yearly global number of cybersecurity incidents activity during the period from 2009-2018 and forecast the figures for next upcoming years 2019-2020. The simulation results showed that the optimal model order to estimate the given cybercrime activity is AR(4) since its corresponds to minimum acceptable predication error values to estimate the signal recording an estimation accuracy of 93.5%.","PeriodicalId":225697,"journal":{"name":"2019 10th International Conference on Information and Communication Systems (ICICS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114146802","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}
