Fighting poverty is one of the main objectives of sustainable development program. In a country like Lebanon, where poverty is a real threat and hidden under a good living looking, the situation should be explored in depth. This paper aims to evaluate the position of Lebanon compared to other Middle East countries in sustainable development. Furthermore, our goal is to reveal the power and weaknesses of resources management, based on income and non-income indicators retrieved from World data bank. For this purpose, we adopted a combination of data mining techniques as tools to study the relationship between these indicators. The K-means clustering technique is used to define the different levels of living. In order to extract the most relevant non-income indicators to our study, information gain as feature selection technique was applied. Finally, KNN classification technique was used for the predicting model.
消除贫困是可持续发展计划的主要目标之一。在黎巴嫩这样的国家,贫困是一个真正的威胁,隐藏在美好生活的表象之下,应该深入探讨这种情况。本文旨在评价黎巴嫩与其他中东国家相比在可持续发展方面的地位。此外,我们的目标是根据从世界数据银行检索到的收入和非收入指标,揭示资源管理的力量和弱点。为此,我们采用组合数据挖掘技术作为工具来研究这些指标之间的关系。使用k均值聚类技术来定义不同的生活水平。为了提取与本研究最相关的非收入指标,采用信息增益作为特征选择技术。最后,利用KNN分类技术建立预测模型。

Automatic segmentation of medical images is a key step in contouring during radiotherapy planning. Computed topography (CT) and Magnetic resonance (MR) imaging are the most widely used radiographic techniques in diagnosis, clinical studies and treatment planning. This paper proposed an unsupervised and automatic estimation of the required parameters for identifying the region of interest. The proposed methodology consists of four steps executed sequentially: First, a body region of interest is masked by a method based on Otsu thresholding and basic morphological operations. Second, a distance transformation is performed then results of distance transform function are normalized. Next, watershed marker-controlled identifications are performed by extract internal and external marker. Finally, the region of interest is identified and segmented according the resulted boundaries. According to the visual evaluation results, segmentation of the human body, from the Computed Tomography images, was seen to be precise and accurate (as confirmed by a specialist). The analysis provided evidence that the human body segmentation method could be applied to segmenting other organs, registering different image modalities or speeding-up the generation of digitally reconstructed radiographs.
医学图像的自动分割是放疗规划中轮廓化的关键步骤。计算机地形图(CT)和磁共振(MR)成像是在诊断、临床研究和治疗计划中应用最广泛的放射学技术。本文提出了一种无监督自动估计感兴趣区域所需参数的方法。该方法由四个步骤组成:首先,使用基于Otsu阈值和基本形态学操作的方法来掩盖感兴趣的身体区域;其次,进行距离变换,对距离变换函数的结果进行归一化处理;其次,通过提取内部和外部标记进行分水岭标记控制鉴定。最后,根据得到的边界对感兴趣的区域进行识别和分割。根据视觉评估结果,从计算机断层扫描图像中对人体的分割是精确和准确的(经专家确认)。分析表明,人体分割方法可以应用于其他器官的分割、不同图像模态的配准或加速数字重建x线照片的生成。

The regular expression is a method to describe strings that conform to a pattern. The need to use regular expressions arise to deal with strings which have a specific pattern such as a user input string, formatted data, and computer programs code elements. In this paper, the authors intend to establish a framework that aims to improve the quality control process to prove that the source code meets standards using a regular expressions. The framework extracts the code from the files then determines if the written code is following the company's own coding standards. The proposed framework covers the naming convention standards, data types utilizations, undesired programming language commands and keywords, hardcoded literals usage, and as well as the business dictionary tags compliance. The short achieved results shows the effectiveness of regular expressions to figure out the compliance of the source code with the standards rules set.
正则表达式是一种描述符合模式的字符串的方法。需要使用正则表达式来处理具有特定模式的字符串,例如用户输入字符串、格式化数据和计算机程序代码元素。在本文中,作者打算建立一个框架,旨在改进质量控制过程,以证明源代码符合使用正则表达式的标准。框架从文件中提取代码,然后确定编写的代码是否遵循公司自己的编码标准。建议的框架涵盖了命名约定标准、数据类型利用、不需要的编程语言命令和关键字、硬编码文字使用以及业务字典标记遵从性。简短的实现结果显示了正则表达式在确定源代码与标准规则集的遵从性方面的有效性。

It is important to reduce the human influence on nature resources by identifying an appropriate land use. Moreover, it is essential to carry out scientific land evaluation. Such kind of analysis allows identifying the main factors for agricultural production and enables decision makers to develop crop managements in order to increase the land capability. The key is to match the type of intensity of land use with its natural capability. Therefore; in order to benefit from these areas and invest them to obtain good agricultural production, they must be organized and managed in full. Lebanon suffers from the unorganized agricultural use. We take South Lebanon as a study area; it is the most fertile ground and has a variety in crops. The study aims to identify and locate the most suitable area to cultivate thirteen types of permanent trees which are: apples, avocadoes, stone fruits in coastal regions and stone fruits in mountain regions, bananas, citrus, loquats, figs, pistachios, mangoes, olives, pomegranates and grapes. Several geographical factors are taken as criterion for selection of the best location to cultivate. Soil, rainfall, PH, temperature, and elevation, are main input to create final map. Input data of each factor is managed, visualized and analyzed using Geographical Information System (GIS). Managements GIS tools were implemented to produce input maps capable of identifying suitable areas related to each index. The combination of the different indices map generates the final output map of the suitable place to get best permanent tree productivity. The output map is reclassified into three suitability classes: low, moderate, and high suitability. Results show different locations suitable for different kinds of trees. Results also reflected the importance of GIS in helping decision makers finding a most suitable location for every tree to get more productivity and a verity in crops.
必须通过确定适当的土地用途来减少人类对自然资源的影响。此外,进行科学的土地评价也是十分必要的。这种分析可以确定农业生产的主要因素,并使决策者能够发展作物管理,以提高土地能力。关键是要使土地利用强度类型与其自然能力相匹配。因此;为了使这些地区受益并投资于农业生产,必须对这些地区进行全面的组织和管理。黎巴嫩的农业利用缺乏组织。我们以黎巴嫩南部为研究区;这是最肥沃的土地,有各种各样的作物。该研究旨在确定和定位最适合种植13种永久性树木的区域,它们是:苹果、鳄梨、沿海地区的核果和山区的核果,香蕉、柑橘、枇杷、无花果、开心果、芒果、橄榄、石榴和葡萄。以若干地理因素作为选择最佳栽培地点的标准。土壤、降雨、PH值、温度和海拔是创建最终地图的主要输入。利用地理信息系统(GIS)对各要素的输入数据进行管理、可视化和分析。采用了管理地理信息系统工具来制作能够识别与每个指数相关的适当区域的输入地图。不同指标图的组合生成了获得最佳永久树生产力的合适位置的最终输出图。输出映射被重新划分为三个适宜性类:低适宜性、中等适宜性和高适宜性。结果表明,不同树种适宜生长的位置不同。结果还反映了GIS在帮助决策者为每棵树找到最合适的位置以提高生产力和作物真实性方面的重要性。

Plant Classification in the Wild: A Transfer Learning Approach 野生植物分类:一种迁移学习方法
Pub Date : 2018-11-01 DOI: 10.1109/ACIT.2018.8672694

Datasets specialized in wildlife usually contain imbalanced classes of natural wild images such as, for instance, plant images, which are acquired from the surrounding environment with natural scene background. Deep neural networks have proven their efficiency in classifying such datasets. However, such an approach requires a workaround to approximately balance the classes in order to prevent the occurrence of overfitting during the training phase of the neural network. Many approaches exist to overcome this problem includes over-sampling, undersampling, generating synthetic samples, data augmentation, etc. The iNaturalist species classification and detection dataset represents a good example of vastly imbalanced datasets. It contains 13 superclasses. This work focuses on the Plantae superclass and builds a Convolutional Neural Network to distinguish a subset of the subclasses of Plantae. Our model benefits from cutting-edge techniques such as transfer learning and data augmentation to obtain a reasonably high level of accuracy (78.76%).
专门用于野生动物的数据集通常包含不平衡的自然野生图像类别,例如植物图像,这些图像是从具有自然场景背景的周围环境中获取的。深度神经网络在分类此类数据集方面已经证明了其有效性。然而,这种方法需要一种变通方法来近似平衡类,以防止在神经网络的训练阶段发生过拟合。有许多方法可以克服这个问题,包括过采样、欠采样、生成合成样本、数据增强等。iNaturalist物种分类和检测数据集是一个非常不平衡的数据集的好例子。它包含13个超类。本研究的重点是Plantae超类,并建立了一个卷积神经网络来区分Plantae亚类的一个子集。我们的模型得益于迁移学习和数据增强等前沿技术,获得了相当高的准确率(78.76%)。

This paper presents a novel architecture of a soft MIMO detector. The proposed architecture is composed of a first block in charge of the calculation of the Euclidean distances. The second one is dedicated to the exchange of information inside the detector over a larger Joint Factor Graph. Thanks to an appropriate parallelism level, the associated architecture enables efficient exchanges of information. Therefore, it promotes a good trade-off between error rate performance and computational complexity which leads to decrease the latency of such receivers.

3D web-based applications started to appear a long time ago thanks for the great conversion of the web browsers into a full runtime environment. Building up an adaptive 3D web-based shape modelling environment enables us to design platform independent 3D objects in a collaborative manner, yet delivering 3D models into different clients with different platforms while maintaining a convincing model quality is a difficult job. In this paper, we explore the crucial issues of rendering heterogeneous volumes in real-time. We focus on implementing a suitable rendering environment that can serve clients with different platform devices. Our case study relies on a client-server adaptive architecture, supported by different rendering techniques, and allows real-time modelling and rendering. Our goal is to create a web-based modelling and rendering environment which supports different rendering approaches that suit a various range of users. We identify the concepts and techniques used to implement such a real-time rendering environment and we present experiments and results based on different rendering techniques.
基于web的3D应用程序很久以前就开始出现了,这要归功于web浏览器向完整运行时环境的巨大转变。建立一个自适应的基于web的3D形状建模环境使我们能够以协作的方式设计独立于平台的3D对象,然而,在保持令人信服的模型质量的同时,将3D模型交付给不同平台的不同客户端是一项艰巨的工作。在本文中,我们探讨了实时呈现异构卷的关键问题。我们专注于实现一个合适的呈现环境,该环境可以为具有不同平台设备的客户端提供服务。我们的案例研究依赖于客户端-服务器自适应架构,由不同的渲染技术支持,并允许实时建模和渲染。我们的目标是创建一个基于web的建模和渲染环境,它支持适合各种用户的不同渲染方法。我们确定了用于实现这种实时渲染环境的概念和技术,并给出了基于不同渲染技术的实验和结果。

The air traffic ground movement management is a main problem for airports. The best optimization of ground movements would reduce flight delays and overall travel costs. This article proposes a new routing algorithm to provide the shortest route based on three algorithms that allow a good planning of ground movements. These three algorithms are iterative: they allow you to plan the trajectory of an aircraft one after the other. The three algorithms are guaranteed as a real-time decision support tool for air traffic controllers, but they each have strengths and weaknesses. A first version is described using the classic Dijkstra algorithm, then the classic Dijkstra version has been extended by a bidirectional version. Both algorithms provide an optimal solution, but the cost of computing time remains relatively long despite an improvement with the use of bidirectional Dijkstra. A third A* algorithm is used. The limitation of this one being that it does not guarantee an optimal solution despite a faster calculation time cost. To eliminate the weaknesses of each algorithm studied, a new Hybrid A* algorithm is therefore presented here. It integrates the advantages of each algorithm to reduce computation time and optimize the search for the shortest path while maintaining a minimum execution time to ensure the feasibility of planned trajectories in a reduced time. This model has been expanded to address the feasibility of planned trajectories while avoiding conflicts between aircraft and evaluated on the model of Casablanca airport Med V.
空中交通地面运行管理是机场面临的主要问题。地面运动的最佳优化将减少航班延误和总体旅行成本。本文提出了一种新的路由算法,在三种算法的基础上提供最短的路由,从而可以很好地规划地面运动。这三种算法是迭代的:它们允许你一个接一个地规划飞机的轨迹。这三种算法都能保证为空中交通管制员提供实时决策支持工具,但它们各有优缺点。第一个版本是使用经典的Dijkstra算法描述的,然后经典的Dijkstra版本被一个双向版本扩展。这两种算法都提供了最优解,但是尽管使用双向Dijkstra进行了改进,但计算时间的成本仍然相对较长。使用第三种A*算法。这种方法的限制是,尽管计算时间成本更快,但它不能保证最优解。为了消除所研究算法的缺点,本文提出了一种新的混合a *算法。它综合了各算法的优点,减少计算时间,优化搜索最短路径,同时保持最小的执行时间,确保在最短时间内规划轨迹的可行性。该模型已得到扩展,以解决计划轨迹的可行性,同时避免飞机之间的冲突,并在卡萨布兰卡机场Med V模型上进行了评估。

Without sunlight there's no life, and without light there's no well-being. Using daylight means saving energy, because daylight is free and is often available in sufficient quantities. It's important to create and find the best techniques to maximize the use of this energy. Since the sun's position in the sky varies according to seasons and time of day, sun simulators are thus important in showcasing the sun's different positions. This paper introduces a sun stimulator system that can be physically built, in which users would enter a specific location on earth and a simulation of the sun's position would be generated according to date and time of year.
没有阳光就没有生命,没有光就没有幸福。使用日光意味着节约能源,因为日光是免费的,而且通常可以获得充足的日光。重要的是创造和找到最好的技术来最大限度地利用这种能量。由于太阳在天空中的位置随着季节和一天中的时间而变化,因此太阳模拟器在展示太阳的不同位置方面非常重要。本文介绍了一种可以物理构建的太阳刺激器系统,用户在该系统中输入地球上的特定位置,根据一年中的日期和时间生成太阳位置的模拟。

Recently, the Project Management Office (PMO) has become the source of change and spirit of innovation within any organization. It determines the success of project management functions and achieves the organization's objectives. However, most banking organizations have a group of waterfall projects within a startup PMO; it is not established to use agile practices and methodologies. Therefore, transforming the waterfall project management office (WPMO) into agile PMO (APMO) is a challenging topic, especially when the organizational structure is not built as strongly projectized structure. This research paper wisely analyzed a real case study for an IT organization to understand all issues facing the WPMO. As a result of this, the research implements a full flexible process called the Scalable Agile Transforming Process (SATP) to transform WPMO into APMO within an IT organization. It also presents a new potential role called change coach, to guide, help, train, and support employees during the transformation journey. The results of this research study revealed the importance of transforming WPMO into APMO by using a clear process and steps. Moreover, this study could be useful and applicable for information technology enterprises.
最近,项目管理办公室(PMO)已经成为任何组织变革和创新精神的源泉。它决定了项目管理职能的成功和组织目标的实现。然而,大多数银行组织在初创公司的PMO中都有一组瀑布式项目;它并不是为了使用敏捷实践和方法而建立的。因此,将瀑布式项目管理办公室(WPMO)转变为敏捷项目管理办公室(APMO)是一个具有挑战性的主题,特别是当组织结构不是作为强投影结构构建时。这篇研究论文明智地分析了一个IT组织的真实案例研究,以了解WPMO面临的所有问题。因此,该研究实现了一个完全灵活的过程,称为可扩展敏捷转换过程(SATP),将IT组织中的WPMO转换为APMO。它还提出了一个新的潜在角色,即变革教练,在转型过程中指导、帮助、培训和支持员工。本研究结果揭示了通过明确的流程和步骤将WPMO转化为APMO的重要性。本研究对信息技术企业具有一定的参考价值和应用价值。
