Multilingual verbal interaction between humans and robots - Modeling and Implementation 人与机器人之间的多语言语言交互。建模与实现
Mohammed Qbadou, M. Zaggaf, Intissar Salhi, K. Mansouri
Language barriers are one of the biggest challenges that humans in general and children in particular face in their verbal interactions. Many reseach projets with mutli-countries scope are expected to give a significant help to teachers and doctors to support children with verbal communication disabilities by using humanoid robots. The usage of robot agent is excpected to stimulate the verbal communication based on natural language interactions with this kind of children. Such stimulation may be of great importance in improving the ability of these children to interact verbally with their teachers and classmates. In this context, we propose through this work to extend the language capabilities of humanoid robots to be able to communicate with children using differnet natural languages. This should allow a humanoid robot to recognize the spoken or written message of each children group and thus use this language to interact with. In this paper, we present the design of a generic models and the implementation of a software components to allow language neutral verbal interactions between children and humanoid robots. An extended ontology models will be provided to serve as a knowledge database of a set of concepts and theirs propoerties to represent the semantic aspects describing the relations between human-robot vebal communications. Based on thus generic models, we will provide an optimized new algorithms and their Python implementation to extend the natural language processing Python pakages. In this paper, a set of human-Robot verbal ineractions models are presented and the resultant conclusions and perspectives are discussed
语言障碍是人类,尤其是儿童在语言交流中面临的最大挑战之一。许多多国范围的研究项目有望为教师和医生使用类人机器人来支持有语言交流障碍的儿童提供重大帮助。机器人代理的使用有望刺激这类儿童基于自然语言交互的言语交流。这种刺激对于提高这些孩子与老师和同学进行口头交流的能力可能非常重要。在此背景下,我们建议通过这项工作扩展类人机器人的语言能力,使其能够使用不同的自然语言与儿童交流。这应该允许人形机器人识别每个儿童群体的口头或书面信息,从而使用这种语言进行互动。在本文中,我们提出了一个通用模型的设计和软件组件的实现,以允许儿童和人形机器人之间的语言中性语言交互。将提供一个扩展的本体模型,作为一组概念及其属性的知识库,以表示描述人机语言通信关系的语义方面。基于这些泛型模型,我们将提供优化的新算法及其Python实现,以扩展自然语言处理Python包。本文提出了一套人机语言交互模型,并对所得结论和观点进行了讨论

Modeling and simulation of a loader and unloader manipulator 装卸机机械手的建模与仿真
My Elhoussine Ech-chhibat, L. Zahiri, L. A. E. Maalem
Industrial production workshops in all fields are becoming more and more robotized. Flexible workshops have several types of robots, namely mobile robots that move products from one machine to another, flexible cells are loaded and unloaded by robot manipulators. In this work we will discuss the design of a serial robot with six degrees of freedom. Three degrees of freedom to position the effector and three others to guide the wrist. In this context the manipulator arm must load and unload a CNC milling machine ‘TORMACH PCNC 440’ which is installed in our lab. The dimensions of the robot are adapted to the size of the machine, these organs are sized by another research team. In what follows we will discuss the different models allowing us the control of the manipulator. We start with the geometric model, the kinematic model and the static model. The goal is to enslave the arm in position and velocity. Several simulations have been carried out to validate this part of our study. Homogeneous transformation and modified DENAVIT-HARTENBURG (DH) parameters are adopted in this approach.

Towards a Spatial Data Warehouse for Occupational Health Risk Management 面向职业健康风险管理的空间数据仓库
Hayat Haroun, A. R. Ghomari, Mounir Lahlouh, Anis Mehdi
Risk assessment is an essential part of any occupational health (OH) management system. Occupational Risk Management Process, is characterized by multiple types of data (activity sector, occupations, risks exposures, diseases, etc.). This multidimensional aspect of data strengthens the need for appropriate tools to enhance OH analysis. This paper examines the opportunity of using spatial data warehousing technique in the OH management framework to integrate various data formats such as geographic (workplace data) and thematic data which are usually scattered across multiple, dispersed and fragmented systems. We propose a SOLAP architecture that supports the whole process of risk management for prevention purposes. We then instantiate the architecture to build a SOLAP-Based System for SMT Company to enhance risk assessment in OH for electrical and gas industries.

Automatic Document Classification using Deep Feature Selection and Knowledge Transfer 基于深度特征选择和知识转移的自动文档分类
Aissam Jadli, M. Hain
Documents in an ERP system flow from different sources (customer, supplier, etc.) and can have different layouts, sizes and subjects (invoices, delivery forms, checks, etc.). The classification of these documents is usually done manually before being saved in the ERP system or processed by an Optical Character Recognition (OCR) engine. In this paper, we investigate using different deep convolutional neural networks (CNN) to extract deep features from images of scanned documents. The extracted features are further processed using various machine learning classifiers such as Logistic Regression (LR), K-Nearest Neighbors (KNN), Support Vector Machine (SVM) and Gaussian Naive Bayes (GNB). Different metrics were used (accuracy, precision, etc.) and examined to compare all models performances, while cross-validation approach at different folds sizes (4, 6, 8 and 10) was used to assess their generalization ability. The effect of dimensionality reduction techniques on overall performances was also explored. The best classification rate was 96.1%, which was achieved by combining LR and the VGG19 model. This very good performance despite the small dataset used (200 images) can allow using this approach in an ERP system as a preprocessing step in document manipulation for ERP users.
ERP系统中的文档来自不同的来源(客户、供应商等),并且可以具有不同的布局、大小和主题(发票、交付表单、支票等)。这些文档的分类通常是手工完成的,然后保存在ERP系统中或由光学字符识别(OCR)引擎处理。在本文中,我们研究了使用不同的深度卷积神经网络(CNN)从扫描文档图像中提取深度特征。提取的特征使用各种机器学习分类器进行进一步处理,如逻辑回归(LR), k近邻(KNN),支持向量机(SVM)和高斯朴素贝叶斯(GNB)。使用不同的指标(准确度、精度等)来比较所有模型的性能,同时使用不同折叠大小(4、6、8和10)的交叉验证方法来评估它们的泛化能力。探讨了降维技术对整体性能的影响。LR与VGG19模型相结合的分类率最高,达到96.1%。尽管使用的数据集很小(200张图像),但这种非常好的性能允许在ERP系统中使用这种方法作为ERP用户文档操作的预处理步骤。

Medical Video Watermarking Scheme for Telemedicine Applications 用于远程医疗应用的医疗视频水印方案
Sabbane Fadoua, Tairi Hamid
Recent advancements in a new era of e-health and telemedicine technologies present newer opportunities for sharing medical data when an open communication channel is used. However, this exchange is facing critical challenges of copyright protection, content authentication, and integrity verification. Therefore, due to the high demand for safe manipulation of patient’s medical information, digital watermarking is required, as a value-added tool, for secure medical data management. In this study, a new reversible watermarking technique for the security of medical videos is proposed. The patient identity is embedded, as a watermark, into the host medical videos. An algorithm is adopted for selecting the optimal frames in each video shot. This approach includes the use of polynomial transform methods, in order to identify the best watermark embedding areas in the optimal frames. Experimental results demonstrate high imperceptibility of the watermark and strong robustness against different attacks. Hence, our algorithm validates the security measures that ensure an effective manipulation of medical videos.
电子保健和远程医疗技术新时代的最新进展为使用开放通信渠道共享医疗数据提供了新的机会。然而,该交易所面临着版权保护、内容认证和完整性验证等关键挑战。因此,由于对患者医疗信息安全操作的要求很高,需要数字水印作为一种增值工具来进行安全的医疗数据管理。本文提出了一种用于医学视频安全的可逆水印技术。患者身份以水印的形式嵌入到主机医疗视频中。采用一种算法来选择每个视频镜头的最优帧。该方法包括使用多项式变换方法,以便在最优帧中识别最佳水印嵌入区域。实验结果表明,该方法具有较高的水印隐蔽性和较强的抗攻击鲁棒性。因此,我们的算法验证了确保有效处理医疗视频的安全措施。

Fully Automatic Computer-Aided Detection of Breast Cancer based on Genetic Algorithm Optimization 基于遗传算法优化的乳腺癌全自动计算机辅助检测
Hamid El Malali, Abdelhadi Assir, Mohammed Harmouchi, A. Lyazidi, M. Rattal, A. Mouhsen
Breast cancer is the second disease causing death in women. The screening of breast cancer for early detection is an effective way to reduce mortality. Generally, mammography is the most effective imaging modality recommended by radiologists. Therefore, a high number of mammogram images have to be analyzed. Indeed, the expertise of radiologists and the quality of the images to be analyzed play a crucial role in the accuracy of the diagnosis. The use of CAD systems allow improving the accuracy of diagnosis by reducing the number of false-positive and the false-negative. In this paper, to assist radiologists to make the right decision by showing them the probably suspect area, a full automatic CADe is presented. The preprocessing step aims at delimiting the ROI by removing artifact and pectoral muscle using global thresholding method, morphological operators and seeded region growing method, followed by contrast enhancement of the ROI found in the first step using the technique named “adaptive local gray level transformation based on variable s-curve”. At last, the ROI is segmented using k-means clustering. Both contrast enhancement method and the segmentation method are performed by genetic algorithm to optimize the outcomes of each step.
乳腺癌是导致妇女死亡的第二大疾病。早期发现乳腺癌的筛查是降低死亡率的有效方法。一般来说,乳房x光摄影是放射科医生推荐的最有效的成像方式。因此,需要分析大量的乳房x光照片。事实上,放射科医生的专业知识和待分析图像的质量对诊断的准确性起着至关重要的作用。CAD系统的使用可以通过减少假阳性和假阴性的数量来提高诊断的准确性。在本文中,为了帮助放射科医生通过显示可能可疑的区域来做出正确的决定,提出了一个全自动CADe。预处理步骤的目的是利用全局阈值法、形态学算子和种子区域生长法去除伪影和胸肌来划分感兴趣区域,然后利用“基于变量s曲线的自适应局部灰度变换”技术对第一步找到的感兴趣区域进行对比度增强。最后,利用k-means聚类对ROI进行分割。对比度增强方法和分割方法均采用遗传算法对每一步的结果进行优化。

A fuzzy dynamic approach to manage optimally the cloud resources 采用模糊动态方法优化管理云资源
A. Mokhtari, M. Azizi, M. Gabli
One of the main challenges in cloud computing is how to manage optimally the cloud resources in response of execution needs; so that both the cost and the time of running users applications are reduced. However, prices may change over time. In this paper, we propose an optimization-based solution which combines a Dynamic Genetic Algorithm (DGA) approach and fuzzy logic. First, we presented the DGA which provides a fair consideration of objectives. Then, we introduced a model based on possibility theory where each cost is taken as a fuzzy variable. For that, we used both possibility and necessity measures. In order to validate our solution, we tested it over some real applications using a set of cloud resources available on the market. The obtained results demonstrate clearly that our algorithms succeeded to find reasonable solutions that fulfill successfully our objectives function.
云计算的主要挑战之一是如何以最佳方式管理云资源以响应执行需求;从而减少了运行用户应用程序的成本和时间。然而,价格可能会随着时间的推移而变化。本文提出一种结合动态遗传算法(DGA)和模糊逻辑的优化解决方案。首先,我们提出了DGA,它提供了对目标的公平考虑。然后,我们引入了一个基于可能性理论的模型,其中每个成本都是一个模糊变量。为此,我们使用了可能性和必要性两种方法。为了验证我们的解决方案,我们使用市场上可用的一组云资源在一些实际应用程序上对其进行了测试。得到的结果清楚地表明,我们的算法成功地找到了满足目标函数的合理解。

However, prices may change over time. In this paper, we propose an optimization-based solution which combines a Dynamic Genetic Algorithm (DGA) approach and fuzzy logic. First, we presented the DGA which provides a fair consideration of objectives. Then, we introduced a model based on possibility theory where each cost is taken as a fuzzy variable. For that, we used both possibility and necessity measures. In order to validate our solution, we tested it over some real applications using a set of cloud resources available on the market.
