This paper aims to fill the gap in major Islamic topics by developing an ontology for the Book of Purification in Islam. Many trusted books start with the Book of Purification as it is the key to prayer (Second Pillar after Shahadah, the profession of faith) and required in Islamic duties like performing Umrah and Hajj. The strategy for developing the ontology included six steps: (1) domain identification, (2) knowledge acquisition, (3) conceptualization, (4) classification, (5) integration and implementation, and (6) ontology generation. Examples of the built tables and classifications are included in this paper. Focus in this paper is given to the design and analysis phases where the technical implementing of the proposed ontology is not within this paper’s objectives. Though, we presented an initial implementation to illustrate the steps of our strategy. We make sure that this ontology or knowledge representation on the Book of Purification in Islam satisfy reusability, where the main attributes, concepts, and their relationships are defined and encoded. This formal encoding will be available for sharing and reusing.
本文旨在通过发展伊斯兰《净化经》的本体论来填补主要伊斯兰主题的空白。许多值得信赖的书籍都以《净化之书》开头,因为它是祈祷的关键(继Shahadah之后的第二大支柱,信仰的职业),也是伊斯兰教履行职责(如进行朝觐和朝觐)所必需的。本体开发策略包括6个步骤:(1)领域识别、(2)知识获取、(3)概念化、(4)分类、(5)集成与实现、(6)本体生成。文中还包括所建表和分类的实例。本文的重点是设计和分析阶段,在这些阶段,所提出的本体的技术实现不在本文的目标范围内。但是,我们提供了一个初始实现来说明我们的策略的步骤。我们确保伊斯兰《净化之书》中的本体或知识表示满足可重用性,其中主要属性、概念及其关系是定义和编码的。这种正式编码将可用于共享和重用。

Particle packings are used to simulate granular matter, which has various uses in industry. The most outstanding characteristics of these are their density and their construction time, the density refers to the percentage of the space of the object filled with particles, this is also known as compaction or solid fraction. Particle packing seeks to be as dense as possible, work on any object, and have a low build time. Currently there are proposals that have significantly reduced the construction time of a packing and have also managed to increase the density of these, however, they have certain restrictions, such as working on a single type of object and being widely affected by the characteristics of the object. The objective of this work is to present the improvement of a parallel sphere packing for arbitrary domains. The packing to improve was directly affected in time by the number of triangles in the mesh of object. This enhancement focuses on creating a parallel data structure to reduce build time. The proposed method reduces execution time with a high number of triangles, but it takes up a significant amount of memory for the data structure. However, to obtain high densities, that is, densities between 60% and 70%, the sphere packing construction does not overwhelm the memory.
颗粒填料用于模拟颗粒状物质,在工业上有各种用途。这些最突出的特点是它们的密度和它们的施工时间,密度是指物体填充颗粒的空间的百分比,这也被称为压实或固体分数。粒子包装寻求尽可能密集,适用于任何对象,并具有较低的构建时间。目前,有一些建议已经大大减少了包装的施工时间,并设法增加了这些密度,然而,它们有一定的限制,例如在单一类型的物体上工作,并且受到物体特性的广泛影响。本文的目的是提出一种改进的任意域的平行球填充方法。物体网格中三角形的数量直接影响改进的填充效果。此增强侧重于创建并行数据结构以减少构建时间。提出的方法减少了大量三角形的执行时间,但它占用了大量的数据结构内存。然而,为了获得高密度,即密度在60%到70%之间,球体填充结构不会压倒内存。

Non-zero inner product encryption provides fine-grained access control to private data, but the existing non-zero inner product encryption schemes are mainly constructed based on the problem of bilinear groups and lattices without homomorphism. To meet the needs of users to control private data and cloud servers to directly process ciphertexts in a cloud computing environment, this paper designs a non-zero inner product encryption scheme based on the DCR assumption. Specifically, the access control policy is embedded in the ciphertext by a vector y, and the user attribute vector x is embedded in the secret key. If the inner product of the policy vector y of the encryptor and the attribute vector x of the decryptor is not zero, the decryptor can decrypt correctly. This scheme has additive homomorphism in the plaintext-ciphertext space, and it can be proved to be additive homomorphic and adaptively secure.
非零内积加密提供了对私有数据的细粒度访问控制,但现有的非零内积加密方案主要是基于双线性群和非同态格的问题构造的。为了满足云计算环境下用户控制私有数据和云服务器直接处理密文的需求,本文基于DCR假设设计了一种非零内积加密方案。具体来说,访问控制策略通过向量y嵌入到密文中,用户属性向量x嵌入到密钥中。如果加密者的策略向量y与解密者的属性向量x的内积不为零,则解密者可以正确解密。该方案在明文-密文空间具有加性同态,证明了该方案是加性同态和自适应安全的。

Classifier algorithms are a subfield of data mining and play an integral role in finding patterns and relationships within large datasets. In recent years, fake news detection has become a popular area of data mining for several important reasons, including its negative impact on decision-making and its virality within social networks. In the past, traditional fake news detection has relied primarily on information context, while modern approaches rely on auxiliary information to classify content. Modelling with machine learning and natural language processing can aid in distinguishing between fake and real news. In this research, we mine data from Reddit, the popular online discussion forum and social news aggregator, and measure machine learning classifiers in order to evaluate each algorithm’s accuracy in detecting fake news using only a minimal subset of data.
分类器算法是数据挖掘的一个子领域,在寻找大型数据集中的模式和关系方面发挥着不可或缺的作用。近年来,假新闻检测已经成为数据挖掘的一个热门领域,原因有几个,包括它对决策的负面影响,以及它在社交网络中的病毒式传播。过去,传统的假新闻检测主要依靠信息语境,而现代方法则依靠辅助信息对内容进行分类。利用机器学习和自然语言处理进行建模可以帮助区分假新闻和真新闻。在这项研究中,我们从Reddit(一个流行的在线讨论论坛和社会新闻聚合器)中挖掘数据,并测量机器学习分类器,以便仅使用最小的数据子集来评估每种算法在检测假新闻方面的准确性。

Monocular Camera Calibration using Projective Invariants 用射影不变量标定单目摄像机
Pub Date : 2022-05-28 DOI: 10.5121/csit.2022.120921

Camera calibration is a crucial step to improve the accuracy of the images captured by optical devices. In this paper, we take advantage of projective geometry properties to select frames with quality control points in the data acquisition stage and, further on, perform an accurate camera calibration. The proposed method consists of four steps. Firstly, we select acceptable frames based on the position of the control points, later on we use projective invariants properties to find the optimal control points to perform an initial camera calibration using the camera calibration algorithm implemented in OpenCV. Finally, we perform an iterative process of control point refinement, projective invariants properties check and recalibration; until the results of the calibrations converge to a minimum defined threshold.
相机标定是提高光学设备捕获图像精度的关键步骤。在本文中,我们利用射影几何特性在数据采集阶段选择具有质量控制点的帧,并进一步执行精确的相机校准。该方法分为四个步骤。首先,我们根据控制点的位置选择可接受的帧,然后我们使用投影不变量属性找到最优控制点,使用OpenCV实现的摄像机校准算法进行初始摄像机校准。最后,我们进行了控制点细化、射影不变量性质检查和重新校准的迭代过程;直到校准结果收敛到最小定义阈值。

Autonomous Vehicles Lateral Control under Various Scenarios 自动驾驶汽车在不同场景下的横向控制
Pub Date : 2022-05-28 DOI: 10.5121/csit.2022.120922
Mohamed Ali Jemmali, Hussein T. Mouftah
In this paper, the autonomous vehicle presented as a discrete-time Takagi-Sugeno fuzzy (T-S) model. We used the discrete-time T-S model since it is ready for the implementation unlike the continuous T-S fuzzy model. The main goal is to keep the autonomous vehicle in the centreline of the lane regardless the external disturbances. These disturbances are the wind force and the unknown curvature; they are applied to test if the autonomous vehicle moves from the centreline. To ensure that the autonomous vehicle remain on the centreline we propose a discrete-time fuzzy lateral controller called also steering controller.
本文将自动驾驶汽车描述为离散时间Takagi-Sugeno模糊(T-S)模型。我们使用离散时间T-S模型,因为它与连续T-S模糊模型不同,它已经准备好实现。其主要目标是使自动驾驶汽车保持在车道的中央,而不受外界干扰。这些扰动是风力和未知曲率;它们被用来测试自动驾驶汽车是否从中心线移动。为了确保自动驾驶车辆保持在中心线上,我们提出了一个离散时间模糊横向控制器,也称为转向控制器。

In this study we applied the CART-type Decision Tree (DT-CART) method derived from artificial intelligence technique to the prediction of the solvency of bank customers, for this we used historical data of bank customers. However we have adopted the process of Data Mining techniques, for this purpose we started with a data preprocessing in which we clean the data and we deleted all rows with outliers or missing values as well as rows with empty columns, then we fixed the variable to be explained (dependent or Target) and we also thought to eliminate all explanatory (independent) variables that are not significant using univariate analysis as well as the correlation matrix, then we applied our CART decision tree method using the SPSS tool. After completing our process of building our model (AD-CART), we started the process of evaluating and testing the performance of our model, by which we found that the accuracy and precision of our model is 71%, so we calculated the error ratios, and we found that the error rate equal to 29%, this allowed us to conclude that our model at a fairly good level in terms of precision, predictability and very precisely in predicting the solvency of our banking customers.

BTF Prediction Model using Unsupervised Learning 基于无监督学习的BTF预测模型
Pub Date : 2022-03-19 DOI: 10.5121/csit.2022.120505

The impressions evoked by textures are called affective textures, and are considered to be important in evaluating and judging the quality of an object. And, technologies for understanding and controlling sensory textures are needed in product design. In this study, we propose a BTF prediction method using DNN as a first attempt to generate textures based on affective texture recognition. The method uses a series of continuously varying viewpoint angles of a texture image as the input signal. This method enables the generation of texture images with continuously changing angles. We tested the validity of the proposed method by using textile, wood and paper. The results show that the proposed method is effective for predicting diffuse reflection optical properties and irregular and regular patterns.

Piano keyboard visualization was very popular right now, but there are very few virtual piano keyboard visualizations right now [1]. I was using unity to show the virtual piano keyboard and then they can play piano pieces by themselves or play a recording online [2]. After that you can listen and see how the recording pieces play it on the visual keyboard to give them a clear idea about how the songs played on a keyboard2 [3]. For those who played by themselves it can let them heard and know also when the visual piano play for them, they can tell if they have offbeat playing or they missing not. Piano4Play is an automated piano transcription and keyboard visualization system using AI and deep learning techniques. The user could upload a recorded piece of music, and our app would visualize the music on a digital piano keyboard. The user could see how the music is played visually in order to help piano beginners to see how the music will be played on piano in order to help them learn more quickly and easier, and advanced players could use the app to see whether they made any mistake when they are playing so they can get some improvement. Our app uses wav and MIDI files, repl, real-time database, google Collab and Unity.
目前钢琴键盘可视化非常流行,但目前虚拟钢琴键盘可视化很少[1]。我使用unity来展示虚拟钢琴键盘,然后他们可以自己演奏钢琴作品或在线播放录音[2]。之后,你可以听录音,看看录音是如何在可视键盘上演奏的,让他们清楚地了解歌曲是如何在键盘上演奏的[3]。对于那些自己演奏的人来说,它可以让他们听到并知道当视觉钢琴为他们演奏时,他们可以告诉他们是否有不寻常的演奏。Piano4Play是一个使用人工智能和深度学习技术的自动钢琴转录和键盘可视化系统。用户可以上传一段录制好的音乐,我们的应用程序会将音乐在数字钢琴键盘上可视化。用户可以直观地看到音乐是如何演奏的,以帮助钢琴初学者看到音乐是如何在钢琴上演奏的,以帮助他们更快更容易地学习,高级玩家可以使用应用程序查看他们在演奏时是否犯了错误,以便他们得到一些改进。我们的应用程序使用wav和MIDI文件,repl,实时数据库,谷歌协作和Unity。

Piano4Play is an automated piano transcription and keyboard visualization system using AI and deep learning techniques. The user could upload a recorded piece of music, and our app would visualize the music on a digital piano keyboard. The user could see how the music is played visually in order to help piano beginners to see how the music will be played on piano in order to help them learn more quickly and easier, and advanced players could use the app to see whether they made any mistake when they are playing so they can get some improvement. Our app uses wav and MIDI files, repl, real-time database, google Collab and Unity.","PeriodicalId":91205,"journal":{"name":"Artificial intelligence and applications (Commerce, Calif.)","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90032127","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}

Paywalls are a staple of the internet and seen in a vast amount of websites [1]. Encountering a paywall is always annoying, whether you’re doing work for school or just trying to catch up on the latest news [2]. To eliminate this annoyance we have created Wall Breaker, a google extension with the primary task of bypassing any paywall using a variety of methods [3]. Our extension uses methods such as opening the website in an incognito tab or acting as a new user when clicking on a link. Although not the first of its kind, our extension is truly unique in the methods and techniques used. The popup used is easy to use and simple to look at, providing the best user experience. Wall Breaker will work on most websites, both popular and lesser known ones. It makes no distinction between certain types of websites and the methods can be used on any page. While Wall Breaker might not work on every website those are few and far between.
付费墙是互联网的主要组成部分,在大量网站中都可以看到[1]。遇到付费墙总是很烦人的,无论你是在为学校做功课还是只是想赶上最新的新闻[2]。为了消除这种烦恼,我们已经创建了破墙者,谷歌扩展的主要任务是绕过任何付费墙使用各种方法[3]。我们的扩展使用的方法,如在一个隐身选项卡打开网站或作为一个新用户时,点击一个链接。虽然不是第一个,但我们的扩展在使用的方法和技术上确实是独一无二的。使用的弹出窗口很容易使用和简单的看,提供最好的用户体验。Wall Breaker将适用于大多数网站,无论是流行的还是不太知名的。它不区分某些类型的网站和方法可以在任何页面上使用。虽然Wall Breaker可能并不适用于每个网站,但这种情况很少。
