Israr Hussain, M. Zohaib, E. Babaei
Presented paper depicts the modeling, simulation of Dc-Dc converter and control of battery charging application with less oscillation during switching of MOSFET. Proposed paper deals with the implementation and design of an actual time maximum power point tracking (MPPT) for (PV) system aimed to increase efficiency of energy conversion. As the photovoltaic system has a non-linear behavior of i-v characteristic curve and because of solar irradiance and temperature changes is directly proportional to the maximum power point. Therefore, to obtain maximum power from Solar array the (P&O) Perturbation and Observation MPPT algorithm is implemented using Buck Boost converter. The charismatic characteristics of PV array at different irradiance and temperature is simulated.
本文介绍了直流-直流变换器的建模、仿真以及MOSFET开关过程中电池充电应用的小振荡控制。为提高光伏发电系统的能量转换效率,提出了一种实时最大功率点跟踪(MPPT)的实现和设计方法。由于光伏系统具有非线性行为,其i-v特性曲线又因太阳辐照度和温度的变化与最大功率点成正比。因此,为了获得太阳能阵列的最大功率,采用Buck Boost变换器实现了P&O摄动与观测MPPT算法。模拟了不同辐照度和温度下光伏阵列的魅力特性。

Computer Vision Based Distance Measurement System using Stereo Camera View 基于立体摄像机视角的计算机视觉距离测量系统
E. Dandıl, K. K. Çevik
In recent years, especially in industrial automation systems, in order for robots to understand their distances and positions according to the target, close to human vision, computer vision systems are needed. Computer vision close to human vision can only be created using stereo cameras. In this study, a computer vision system is developed using the stereo camera system for measuring object distances. In the study, first of all, for the distance measurement, the distance of the face images obtained from the stereo camera system to the screen is calculated. In measuring the distances of the face images to screen, the disparity maps are first extracted and the face region is detected. Afterwards, the distance measurements are performed on the obtained images in the stereo camera system on account of calculating the shifts between the frames. In the experimental studies, the actual distance values such as 71, 74, 75, 79, 110, 125, and 115 of the face to the screen are measured as 70, 72, 73, 77, 97, 120, 132 cm by proposed system, respectively. When the experimental results are examined, we can say that the proposed computer vision system is successful in distance measurement using stereo camera view.
近年来,特别是在工业自动化系统中,为了使机器人根据目标,接近人类的视觉来了解自己的距离和位置,需要计算机视觉系统。接近人类视觉的计算机视觉只能通过立体摄像机来实现。在本研究中,开发了一种利用立体相机系统测量物体距离的计算机视觉系统。在本研究中,首先,对于距离测量,计算从立体摄像系统获得的人脸图像到屏幕的距离。在测量人脸图像到屏幕的距离时,首先提取视差图并检测人脸区域。然后,通过计算帧间的位移,对获得的图像在立体相机系统中进行距离测量。在实验研究中,所提出的系统分别测量了人脸到屏幕的实际距离值71、74、75、79、110、125、115分别为70、72、73、77、97、120、132 cm。通过对实验结果的检验,我们可以说所提出的计算机视觉系统在立体摄像机视图的距离测量中是成功的。

Serdar Ekinci, A. Demirören, B. Hekimoğlu, Erdal Eker
In this study, an efficient tuning method based on hybrid whale optimization algorithm with simulated annealing (WOA-SA) for optimum parameters setting of proportional + integral + derivative (PID) controller for magnetic ball suspension system is presented. High quality solutions can be achieved via WOA-SA algorithm with balanced local and global search capabilities. Comparative analyzes were conducted to evaluate the performance of the WOA-SA tuned PID controller designed to increase the stability profile of the system. The original whale optimization algorithm (WOA) and simulated annealing (SA) algorithm were used for performance comparison of the hybrid algorithm. The graphical and numerical results obtained from the convergence curve, transient response analysis and frequency response analysis showed that the proposed WOA-SA tuned system has a more stable structure. The essence and novelty of this study is the successful implementation of the proposed hybrid algorithm-based controller design procedure to the magnetic ball suspension system.

Open Source Web-Based Software to Evaluate Normal Distribution: Normality Assessment Software 基于web的评估正态分布的开源软件:正态性评估软件
A. Arslan, Z. Tunç, C. Colak
In this study, it was aimed to develop a new user-friendly web-based software that would easily test single-variable univariate and multivariate normal distribution suitability and enable users to get more accurate results in their studies.Shiny, an open source R package, was used to develop the proposed web software. In the developed software, Shapiro-Wilk and Anderson-Darling tests were used for the uniformity of univariate distribution, and Mardia's skewness-kurtosis, Henze-Zircon and Doornik-Hansen tests were used for multivariate normal distribution. Outputs for conformity to normal distribution were supported by using graphical methods. In practice, for the data set where each variable consisting of two variables derived by simulation has a standard normal distribution and the variables contain 1000 observations, the normal distribution conformity analysis has been performed. In the derived data set, each variable is normally distributed according to the Anderson-Darling and Shapiro-Wilk tests.In addition, the derived data set showed normal distribution with three variables according to Mardia's skewness-kurtosis and Henze-Zirkler tests. However, according to the Doornik-Hansen test, the triple does not show normal distribution.The developed software is a new user-friendly web-based software that can easily perform univariate and multivariate normal distribution conformity analysis and enable users to get more accurate results in their work. In further studies, Type I and Type II error types are planned to be included in the software in order to determine the best method.
本研究旨在开发一种新的用户友好的基于web的软件,可以轻松地测试单变量、单变量和多变量正态分布的适用性,使用户在研究中得到更准确的结果。Shiny是一个开源的R包,用于开发拟议的web软件。在开发的软件中,单变量分布均匀性采用Shapiro-Wilk检验和Anderson-Darling检验,多变量正态分布采用Mardia偏峰度检验、Henze-Zircon检验和Doornik-Hansen检验。采用图形化方法对符合正态分布的输出进行支持。在实践中,对于模拟得出的由两个变量组成的每个变量具有标准正态分布且变量包含1000个观测值的数据集,进行了正态分布符合性分析。在导出的数据集中,根据Anderson-Darling和Shapiro-Wilk检验,每个变量都是正态分布的。此外,根据Mardia偏峰度检验和Henze-Zirkler检验,导出的数据集呈三变量正态分布。然而,根据Doornik-Hansen检验,这三组不表现为正态分布。开发的软件是一种新的用户友好的基于web的软件,可以方便地进行单变量和多变量正态分布的符合性分析,使用户在工作中得到更准确的结果。在进一步的研究中,计划将第一类和第二类误差类型纳入软件中,以确定最佳方法。

Along with the development of technology, new problems emerge. One of these problems is the protection of information. Nowadays, many studies about the protection of information are done. Biometric systems are the most important ones among these studies. Biometric systems are, briefly, the systems which decides whether the Access to the system will be restrcted or not using the distinguishing characteristics of people. For example, every person has different fingerprints, and thanks to the fingerprint sensors of out cell phones, computers, and door entrances accessing problem is solved. However, the increase in the number of passwords means the increase in the level of security. This is why, variety in biometric systems provides an increase in the security. Our project is based on nailprints which are another distinguishing characteristics of people Five images were taken for each of the seven different person. Three images were taken to train the program, and two images were taken to test the program. These images were put through a proces of Segmentation, and the features of these images were extracted.

随着技术的发展,新的问题出现了。其中一个问题是信息保护。如今,关于信息保护的研究已经做了很多。在这些研究中,生物识别系统是最重要的。简而言之,生物识别系统是利用人们的显著特征来决定是否限制对系统的访问的系统。例如,每个人都有不同的指纹,由于我们的手机,电脑和门入口的指纹传感器,解决了访问问题。但是,密码数量的增加意味着安全级别的提高。这就是为什么生物识别系统的多样性提高了安全性。我们的项目基于指甲印,这是人的另一个显著特征,我们为七个不同的人每人拍了五张照片。用三张图片来训练程序,用两张图片来测试程序。对这些图像进行分割,提取图像的特征。利用所提取的特征分类算法,建立了一个能够对可能的指甲图像进行比较的模型。

A Model Based Approach for Android Design Patterns Detection 基于模型的Android设计模式检测方法
Diaeddin Rimawi, Samer Zein
Design patterns in software development have shown great promise in improving software quality. Traditionally, software developers utilize a set of design patterns to foster reusability and better software design. Recently, mobile applications (apps) have become a mainstay of modern computing, as well as, a challenging domain for software engineers. This is because mobile apps now target more critical domains such as health, banking, m-payments, and even military to mention just a few. Android is a very popular mobile platform, and has managed to take over the majority of mobile market. It is true that there are comprehensive studies in the area of design patterns detection in several object-oriented languages such as Java, C# and C++. However, little studies target design patterns in Android apps. As a step toward helping to measure and explore the application of design patterns in Android apps, we introduce PatRoid, an automated framework for detecting design patterns. PatRoid is a model-based approach that is able to detect design patterns laying inside Android apps source code. The model is based on a graph isomorphism approach, where design patterns are divided into sub-patterns that can be aggregated to formulate design patterns. We have conducted a preliminary evaluation and the results show that PatRoid can detect all of the 23 GoF design patterns.
软件开发中的设计模式在提高软件质量方面显示出了巨大的希望。传统上,软件开发人员利用一组设计模式来促进可重用性和更好的软件设计。最近,移动应用程序(app)已经成为现代计算的支柱,同时也是对软件工程师具有挑战性的领域。这是因为移动应用程序现在瞄准的是更关键的领域,比如医疗、银行、移动支付,甚至军事等等。Android是一个非常受欢迎的手机平台,并且已经成功占领了大部分手机市场。的确,在一些面向对象语言(如Java、c#和c++)中,对设计模式检测领域进行了全面的研究。然而,很少有研究针对Android应用的设计模式。为了帮助度量和探索设计模式在Android应用程序中的应用,我们介绍了PatRoid,一个用于检测设计模式的自动化框架。PatRoid是一种基于模型的方法,能够检测Android应用程序源代码中的设计模式。该模型基于图同构方法,其中将设计模式划分为子模式,这些子模式可以聚合以形成设计模式。我们进行了初步的评估,结果表明PatRoid可以检测到所有23种GoF设计模式。

The Design and Development of an Extrusion System for 3D Printing Cementitious Materials 3D打印胶凝材料挤压系统的设计与开发
Abdulrahman Albar, M. Swash, S. Ghaffar
Additive manufacturing (AM), popularly known as ‘3D printing’, is a manufacturing technique that builds physical 3D objects layer by layer using materials such as polymers, metals, and cementitious composites. The widespread popularity of additive manufacturing in most industries ranging from biomedical to aerospace suggests a revolution in manufacturing which has recently emerged to the construction sector. Considered as the future of construction, AM is used in 3D concrete printing due to its benefits in reducing the waste and contributing towards circular economy goals through the use of recovered waste materials from demolition sites. This paper presents an active extrusion system for the 3D printing of cementitious materials for the construction industry. The system has been designed from first principles and therefore can be extended to other materials and scaled up with slight hardware modifications. A robust design has been realized using an unconventional yet simplistic approach. The extrusion system uses some additions to the design to generate a consistent output of material throughout a print. The effectiveness of the extruder is demonstrated through an extensive printing and testing of various printed objects.
增材制造(AM),俗称“3D打印”,是一种使用聚合物、金属和胶凝复合材料等材料逐层构建物理3D物体的制造技术。增材制造在从生物医学到航空航天等大多数行业的广泛普及表明,制造业的一场革命最近已经出现在建筑行业。AM被认为是建筑的未来,它被用于3D混凝土打印,因为它可以减少浪费,并通过使用从拆迁现场回收的废料来实现循环经济目标。本文介绍了一种用于建筑行业胶凝材料3D打印的主动挤出系统。该系统是根据第一性原理设计的,因此可以扩展到其他材料,并通过轻微的硬件修改进行缩放。一个强大的设计已经实现使用非常规的,但简单的方法。挤压系统使用了一些附加的设计,以在整个打印过程中产生一致的材料输出。挤出机的有效性是通过广泛的打印和各种打印对象的测试来证明的。

Classification of brain tumor types by deep learning with convolutional neural network on magnetic resonance images using a developed web-based interface 基于卷积神经网络对磁共振图像进行深度学习的脑肿瘤类型分类
Hasan Ucuzal, Şeyma Yaşar, C. Colak
Automated machine learning (AutoML) algorithms developed using deep learning algorithms have been the focus of interest in many studies recently. This study aims to develop a free web-based software based on deep learning that can be utilized in the diagnosis and detection of brain tumors (Glioma/Meningioma/Pituitary) on T1-weighted magnetic resonance imaging. The Keras library, which is used in Python programming language, is utilized in the construction of the deep learning algorithm in this software. The experimental results show that this software can be used for the detection and diagnosis of three types of brain tumors. This developed web-based software can be publicly available at http://biostatapps.inonu.edu.tr/BTSY/ in both English and Turkish.
