Unit testing allows developers to refactor their code confidently, these tests act as a safety net against producing bugs and provide immediate feedback during the refactoring process and furthermore help developers overcome the fear of change. When performing refactoring, the design of code is changed or restructured according to a predefined plan, after refactoring is applied, the alignment between source code and its corresponding unit tests could be broken which creates a problem that needs to be solved.This paper introduces an approach in which code refactoring can maintain the integrity of the previous unit tests; the tool called GreenRef demonstrates this work. This tool supports an automatic recovery for the unit tests after performing of three particular refactoring types for Java programming language: Rename Method, Add Parameter and Remove Parameter.The achieved results indicate that GreenRef facilitates consistent use of refactoring and unit tests, and save about 43% of the time required to recover broken unit tests manually.
单元测试允许开发人员自信地重构他们的代码,这些测试充当防止产生错误的安全网,并在重构过程中提供即时反馈,进一步帮助开发人员克服对更改的恐惧。在执行重构时,根据预先确定的计划更改或重构代码的设计,在应用重构后,源代码与其对应的单元测试之间的对齐可能会被破坏,从而产生需要解决的问题。本文介绍了一种代码重构方法,该方法可以保持先前单元测试的完整性;名为GreenRef的工具演示了这项工作。该工具支持在执行Java编程语言的三种特定重构类型(重命名方法、添加参数和删除参数)之后对单元测试进行自动恢复。获得的结果表明,GreenRef促进了重构和单元测试的一致使用,并节省了手动恢复损坏的单元测试所需的大约43%的时间。

Taking an appointment means go to the medical center, asking about the suitable doctor for your case, spend a lot of time, or make a phone call, or take an appointment with general doctor, after that let he/she decide to which specialists you have to go; it is very long, and boring process. The main aim of this research is supporting Smart Cities Approach in UAE by designing and implementing system and mobile application “Mwa3edk” to add new concepts for the process of taking appointments with doctors in hospitals and medical clinics by transferring this process into the online world technology. This system will be able to connect a huge number of hospitals and clinics with users over UAE; and enable people to look for doctors in different locations and take appointments that suite them. In addition, users can describe their symptoms then the application will give them recommendations according to what they described using the embedded artificial intelligent method, this will help users to avoid one step, where they can take appointment directly with a specialized doctor instead of meeting the general doctor first.
预约是指去医疗中心,询问适合你的医生,花很多时间,或者打电话,或者预约全科医生,然后让他/她决定你要去哪个专科;这是一个漫长而无聊的过程。这项研究的主要目的是通过设计和实施系统和移动应用程序“Mwa3edk”来支持阿联酋的智慧城市方法,通过将这一过程转移到在线世界技术,为医院和医疗诊所与医生预约的过程添加新概念。该系统将能够将阿联酋的大量医院和诊所与用户连接起来;并使人们能够在不同的地方寻找医生,并接受适合他们的预约。此外,用户可以描述自己的症状,然后应用程序将根据他们描述的使用嵌入式人工智能方法给出建议,这将帮助用户避免一步,他们可以直接与专业医生预约,而不是先与普通医生见面。

Freezing of gait (FoG) is one of the Parkinson’s disease (PD) symptoms that appears as an episodic incapability to walk. It usually occurs in patients with advanced PD, and it is a common reason for falls and injury in Parkinson’s disease patients. Freezing of gait must be carefully monitored because it not only decreases the patient’s quality of life, but also significantly rises the risk of injury. In this work, we presented an automatic freezing of gait detection system that is based on the convolutional neural networks (CNNs). The proposed system can perform automatic feature learning and distinguish between freezing events and normal gait. The proposed system eliminates the need for manually extract features and feature selection. The data was collected using five sensors: two telemeters, two accelerometers, and one goniometer. The proposed architecture discriminated the freezing events from the normal walking with an accuracy, specificity, and sensitivity more than 95%.
步态冻结(FoG)是帕金森病(PD)的症状之一,表现为间歇性无法行走。它通常发生在晚期PD患者中,是帕金森病患者跌倒和受伤的常见原因。步态冻结必须仔细监测,因为它不仅会降低患者的生活质量,而且还会显著增加受伤的风险。在这项工作中,我们提出了一种基于卷积神经网络(cnn)的步态自动冻结检测系统。该系统可以进行自动特征学习,并区分冻结事件和正常步态。该系统消除了手动提取特征和选择特征的需要。数据收集使用五个传感器:两个遥测仪,两个加速度计和一个角计。所提出的结构区分冻结事件和正常行走的准确性、特异性和灵敏度超过95%。

The number of malware in Android environment is increasing. As a result, the conventional detection algorithms that employ signature detection methods are facing challenges to cope with the huge number of attacks. In this respect, a supervised-based model that can enhance the accuracy and the depth of the malware detection and categorization process using a conversation-level feature is presented. The ensemble learning technique was employed in order to select the most useful features. A comparison between the methods provided in this research and the results of other studies that used the same dataset is given. The results show that Extra-trees classifier had achieved the highest weighted accuracy percentage among the other classifiers by 87.75% for malware detection and 79.97% for malware categorization. Finally, this study has achieved significant enhancement in malware categorization rate by 30.2% for precision and 31.14% recall in comparison with other studies that used the same dataset.

the more (IoT) scales up with promises, the more security issues raise to the surface and must be tackled down. IoT is very vulnerable against DoS attacks. In this paper, we propose a hybrid design of signature-based IDS and anomaly-based IDS. The proposed hybrid design intends to enhance the intrusion detection and prevention systems (IDPS) to detect any DoS attack at early stages by classifying the network packets based on user behavior. Simulation results prove successful detection of DoS attack at earlier stages.

Generative adversarial networks (GANs) can be used in modeling highly complex distributions for real world data, especially images. This paper compares between two different models of the Generative Adversarial Networks: the Multi-Agent Diverse Generative Adversarial Networks (MAD-GAN) which consists of multi-generator and one discriminator and the Generative Multi-Adversarial Networks (GMAN) that has multiple discriminators and one generator. The results show that both MAD-GAN and GMAN outperformed the DCGAN. In addition, MAD-GAN performs better than GMAN when avoiding mode collapse or when the dataset contains many different modes.

Modeling Collision Avoidance Field for Overtaking Moving Obstacles 超车运动障碍物避碰场建模

The capability of overtaking moving obstacles is an essential factor for accomplishing several aspects of pedestrian walking flow. In the Hajj area, for example, overtaking dynamic structures constituted by groups, barriers, and other moving obstacles is a vital phenomenon emerged while performing Hajj rituals. In emergency situation, the awareness of the dynamic behavior of moving obstacles is indispensable for achieving typical evacuation. This article proposes an essential intelligence approach to performing further realistic evacuation simulations. We provide each agent with the capability of selecting intermediate destination that enables him reaching his preferred destination; the agent continuously adapts his own trajectory that enables him to overtake such dynamic obstacles by selecting intermediate destinations to pass through. A collision avoidance field which composes of two-dimension grid of cells is proposed to cover the floor of the physical environment. The agent selects the optimal cells which achieve less potential of collision and minimize the distance to the original destination. The proposed model is integrated in a microscopic crowd dynamics model, and simulations are performed to examine the impact of the extended model on introducing further realistic and efficient evacuation.
超车能力是实现行人行走流的几个方面的关键因素。例如,在朝觐地区,超越由群体、障碍和其他移动障碍构成的动态结构是朝觐仪式中出现的重要现象。在紧急情况下,了解移动障碍物的动态行为是实现典型疏散的必要条件。本文提出了一种基本的智能方法来执行进一步的真实疏散模拟。我们为每个agent提供选择中间目的地的能力,使其能够到达自己的首选目的地;智能体不断调整自己的轨迹,通过选择中间目的地来超越这些动态障碍物。提出了一种由二维网格单元构成的避碰场,以覆盖整个物理环境。智能体选择碰撞可能性较小、到原目的地距离最小的最优单元。将该模型集成到微观人群动力学模型中,并进行了仿真,以检验扩展模型对引入更现实、更有效的疏散的影响。

In the Hajj area, for example, overtaking dynamic structures constituted by groups, barriers, and other moving obstacles is a vital phenomenon emerged while performing Hajj rituals. In emergency situation, the awareness of the dynamic behavior of moving obstacles is indispensable for achieving typical evacuation. This article proposes an essential intelligence approach to performing further realistic evacuation simulations. We provide each agent with the capability of selecting intermediate destination that enables him reaching his preferred destination; the agent continuously adapts his own trajectory that enables him to overtake such dynamic obstacles by selecting intermediate destinations to pass through.
