Two Islamic parchments dating back to the IXth century along with a third Jewish one whose age is unknown were investigated by means of a completely non-invasive multi-techniques analysis combining all of elemental XRF and structural Raman, ATR-FTIR and FOR spectroscopies. The materials initially used in the preparation of the writing supports were identified; while the Islamic parchments seem to be condensed tannins-pretreated, hydrolysable tannins and lead white have been highlighted in the Jewish one. Collagen gelatinization with molecular helix disorders phenomena have been highlighted in all parchments; degradation products, gypsum and calcium oxalates, have been identified in parchments supports and writing black inks. These latter have been characterized as iron gall types, while all coloring materials have been identified and characterized: Gold, natural minerals and insect extracts. In addition to constituting valuable scientific data prior to future restorations, the obtained results are highly helpful to: i) improving the available codicological data, ii) establishing the traceability of the investigated parchments and iii) enriching the knowledge of ancient writing supports and materials, and highlighting technologies and practices developed by middle ages craftsmen.
研究人员利用一种完全无创的多技术分析方法,结合了所有元素XRF和结构拉曼光谱、ATR-FTIR和FOR光谱,研究了两份可追溯到8世纪的伊斯兰羊皮纸和第三份年龄未知的犹太羊皮纸。确定了最初用于准备书写支撑的材料;伊斯兰的羊皮纸似乎是浓缩的单宁酸——经过预处理,可水解的单宁酸和铅白在犹太教的羊皮纸中被强调了出来。在所有的文献中都强调了胶原蛋白凝胶化的分子螺旋紊乱现象;降解产物,石膏和草酸钙,已经在羊皮纸支架和书写黑色墨水中发现。后者已被表征为铁胆类型,而所有的着色材料已被鉴定和表征:金,天然矿物和昆虫提取物。除了为未来的修复提供有价值的科学数据外,所获得的结果对以下方面非常有帮助:1)改善现有的法典数据,2)建立所调查羊皮纸的可追溯性,3)丰富古代书写支撑和材料的知识,并突出中世纪工匠开发的技术和实践。

This paper applies Model-Based Design methodologies to develop a high-performance device driver model suitable for advanced smart solutions. These modeling techniques are mandatory to use when designing advanced smart applications based on embedded devices. The paper proposes an innovative approach to accurately models the operations of the STM32 analog converter peripheral for both simulation purpose and to generate an optimized code that integrates on the Low-Level STM32 firmware driver. A new Simulink toolbox has been developed to replicate the ADC functions. Finally, an example has been presented to show the effectiveness of this new modeling approach.

Coronavirus disease 2019 (Covid-19) has plunged the world into a crisis that will forever be marked in the annals of humanity. Several mobile applications have been proposed, in particular to help limit or even stop the spread of the virus. In this paper, we propose a mobile data collection application, LISUNGIcovid19. This application has been built on the basis of the Open Data Kit (ODK) platform. The proposed solution offers both a mobile application and a data server to store, visualize and analyze the collected data. Although there are several applications created in this context of covid-19 such as STOPcovid or Wiqaytna, our solution is distinguished by the rapid adaptation of its data collection form according to the evolution of lockdown exit or renewed lockdown strategy adopted by the authorities. It will help decision-makers in the evaluation of their strategy and possibly the planning of lockdown exit and thus ensure a good management of the way out of this health crisis. The data collected by LISUNGIcovid19, as well as the analysis it proposes of this data, will enable the competent authorities to take the decision to quarantine, or isolate a city, a neighborhood or a group of individuals; or to start planning a progressive lockdown exit or even a new social isolation if necessary. The case study carried out in Morocco to test LISUNGIcovid19 helped to understand the classification of the cities of Casablanca, Rabat and Salé in zone 2 during the first phase of lockdown exit and then in zone 1 during its second phase; while the cities of Kenitra and Marrakech remained in zone 2 during both phases.
2019冠状病毒病(Covid-19)使世界陷入了一场将永远载入人类史册的危机。已经提出了几个移动应用程序,特别是帮助限制甚至阻止病毒的传播。在本文中,我们提出了一个移动数据采集应用程序,LISUNGIcovid19。该应用程序是在开放数据工具包(ODK)平台的基础上构建的。提出的解决方案提供了一个移动应用程序和一个数据服务器来存储、可视化和分析收集到的数据。虽然在2019冠状病毒病背景下创建了几个应用程序,如STOPcovid或Wiqaytna,但我们的解决方案的特点是,根据当局采取的封锁出口或新的封锁策略的演变,快速调整其数据收集形式。这将有助于决策者评估其战略,并可能规划封锁退出,从而确保妥善管理摆脱这场健康危机。lisungicvid19收集的数据,以及它对这些数据提出的分析,将使主管当局能够决定对一个城市、一个社区或一群人进行检疫或隔离;或者开始计划逐步封锁退出,甚至在必要时进行新的社会隔离。为测试LISUNGIcovid19而在摩洛哥进行的案例研究有助于了解卡萨布兰卡、拉巴特和萨尔萨尔等城市在封锁退出第一阶段被划分为第2区,然后在第二阶段被划分为第1区;而肯尼特拉和马拉喀什在这两个阶段仍处于第2区。

Learners in e-learning environments often try to go beyond what can be provided to them by teachers in terms of educational resources, trying to find other external resources on the web related to their preferences and needs. Based on this observation, and with the goal of personalizing the learning process by recommending the most appropriate teaching resources to learners, we propose a model for analyzing learners' searches to determine the relevant words that reflect their interests, with the aim of enriching their profiles. Our approach is to collect the descriptions of the links returned by the search engine, which will constitute a corpus on which we will apply the TF-IDF (term frequency-inverse document frequency) method to determine the relevant words. We will then use the Word2vec technique to determine words similar to these relevant words in the description of internal educational resources, so that we can recommend those that best correspond to the learner's needs. We developed a platform and launched an experiment with a group of real students. The data generated will be analyzed and the results will allow us to evaluate our approach and also to see areas for improvement.
在电子学习环境中,学习者往往试图超越教师提供给他们的教育资源,试图在网络上寻找与他们的偏好和需求相关的其他外部资源。基于这一观察,并以通过向学习者推荐最合适的教学资源来个性化学习过程为目标,我们提出了一个模型,用于分析学习者的搜索,以确定反映他们兴趣的相关单词,以丰富他们的档案。我们的方法是收集搜索引擎返回的链接的描述,这将构成一个语料库,我们将在其上应用TF-IDF(术语频率-逆文档频率)方法来确定相关的单词。然后,我们将使用Word2vec技术来确定内部教育资源描述中与这些相关单词相似的单词,以便我们可以推荐最符合学习者需求的单词。我们开发了一个平台,并在一群真正的学生中开展了一个实验。生成的数据将被分析,结果将使我们能够评估我们的方法,并看到需要改进的地方。

Deep learning methods and applications have become an integral part of all finance subfields. Fraud detection is one of these subfields where these applications managed to save billions of dollars every year. However, one weakness of these models is that we cannot understand what rules they follow to make their decisions. This paper aims to introduce a novel deep learning approach to detect fraud in e-commerce, taking into consideration the problem mentioned above by extracting if-then rules using CRED algorithm (a Continuous/discrete Rule Extractor via Decision tree induction) that employs decision trees to extract these rules. Besides using feature aggregation and re-sampling method on two highly imbalanced data-sets, we conducted a comparative study with previous work. The results show that our model gives better performance.
深度学习方法和应用已经成为所有金融子领域不可或缺的一部分。欺诈检测是这些应用程序每年设法节省数十亿美元的子领域之一。然而,这些模型的一个弱点是我们无法理解它们遵循什么规则来做出决定。本文旨在引入一种新的深度学习方法来检测电子商务中的欺诈行为,考虑到上面提到的问题,使用CRED算法(通过决策树归纳的连续/离散规则提取器)提取if-then规则,该算法使用决策树提取这些规则。除了在两个高度不平衡的数据集上使用特征聚合和重采样方法外,我们还与前人的工作进行了比较研究。结果表明,该模型具有较好的性能。

In this paper we present our Cloud-based Framework for Knowledge Sharing on Early Diagnosis of Dyslexia for the Arabic Language. The Framework allows the intelligent generation of sentences containing forms of dyslexia that are susceptible to being mispronounced by the child. The Framework also extracts the forms of dyslexia present in a sentence and evaluates the patient's achievements. We exploit the innovative techniques of knowledge representation and parallel processing of big data to ensure the efficiency and speed necessary for such real time applications. The Framework architecture is based on Apache HDFS, Apache SPARK and HBase. Our system is designed to be easily integrated into mobile games and applications. The results of the tests carried out are encouraging.

Representing and processing digital data related to underground networks, particularly sewerage networks, is increasingly becoming a priority for the managers of these networks. Indeed, better representation would allow them, among others, to improve knowledge and to take the best decisions regarding these generally poorly identified infrastructures. The heterogeneity of data and the multiplicity of data models representing sewerage networks, often specific to each operator, as well as the imperfections associated with both the available data and those collected from different sources, generate complexity in terms of on-the-field interventions' efficiency. They also highlight the need for aggregation (unification), control and analysis. The main objective of our work is to merge multi-source data to obtain more precise and complete digital maps of sewerage networks. In this paper, we propose a generic data modelling for data fusion purposes taking into consideration the uncertainty aspects related to the collected data by allowing a confidence value for each data source and for each single data provided by a source.
表示和处理与地下网络,特别是污水网络有关的数字数据,正日益成为这些网络管理人员的优先事项。事实上,更好的代表权将使他们,除其他外,能够增进知识,并对这些通常不太确定的基础设施作出最佳决定。数据的异质性和代表污水管网的数据模型的多样性(通常针对每个运营商),以及与可用数据和从不同来源收集的数据相关的不完善,在现场干预的效率方面产生了复杂性。它们还强调了对聚合(统一)、控制和分析的需求。我们工作的主要目标是合并多源数据,以获得更精确和完整的污水管网数字地图。在本文中,我们提出了一种用于数据融合目的的通用数据建模,考虑到与收集数据相关的不确定性方面,允许每个数据源和数据源提供的每个单个数据的置信度值。

In this paper, we discuss the application of Multispectral Imaging combined with statistical algorithms for enhancing hidden patterns to reveal part of the no more readable hieroglyphics in an ancient Egyptian stele. A series of images was taken at different wavelengths of the upper part of the stele S.6145, coming from the archaeological site of Deir El-Medina (Egypt) and currently stored at the Egyptian Museum of Turin (Italy). The analysis of the single images did not allow retrieving the information on the hieroglyphic text. However, the application of Blind Source Separation algorithms allowed to reveal the hidden pattern in a fast and highly efficient way, restoring the correct readability and the value of the artwork itself.
在本文中,我们讨论了应用多光谱成像结合统计算法来增强隐藏模式,以揭示古埃及石碑中部分不太可读的象形文字。以不同波长对S.6145石碑上部拍摄了一系列图像,该石碑来自于Deir El-Medina(埃及)考古遗址,目前保存在都灵埃及博物馆(意大利)。对单个图像的分析不允许检索有关象形文字的信息。然而,盲源分离算法的应用可以快速高效地揭示隐藏的图案,恢复正确的可读性和艺术品本身的价值。

Computer and video games are the subject of intensive and wide-ranging research within the scientific community. The spectrum ranges from the analyses of the effects of games on the propensity to violence, well-being or on the the learning process. Previous works largely concluded positive effects of games on the learning behaviour, particularly at the motivational level. However, the analysis has mainly focused on specially designed educational games, not on games from the entertainment sector that are established on the market. Here, we address this gap by identifying suitable games and examining them for intersections with a catalogue of economical learning objectives. For this purpose, this catalogue is transformed into an adapted criteria catalogue and examined on the basis of five selected games. The main findings include that on average there is a 56% thematic overlap between the learning objectives catalogue, while 18% of the objectives were explained in a way that an abstracted application is possible even outside the gaming environment. Those findings highlight the potential value of these games for an application within the educational sector while suggesting the necessity for adjustments and additions to better address the objectives.
电脑和视频游戏是科学界广泛深入研究的课题。这个范围包括分析游戏对暴力倾向、幸福感或学习过程的影响。之前的研究基本上得出了游戏对学习行为的积极影响,特别是在动机层面。然而,分析主要集中在专门设计的教育类游戏,而不是市场上的娱乐类游戏。在这里,我们通过识别合适的游戏并检查它们与经济学习目标目录的交集来解决这一差距。为此,这个目录被转换成一个改编的标准目录,并在五个选定游戏的基础上进行审查。主要发现包括,平均而言,学习目标目录之间有56%的主题重叠,而18%的目标以一种抽象应用的方式解释,即使在游戏环境之外也是可行的。这些发现强调了这些游戏在教育领域应用的潜在价值,同时也提出了调整和补充的必要性,以更好地实现目标。
