Sadık Yildiz, M. Burunkaya
In this paper, open source and modular smart home system is designed and implemented. The Consumer Internet of Objects (CIoT) approach is adopted in this design. WiFi-based CIoT network has been designed to monitor energy consumption in smart homes. In the CIoT network, the current and voltage values have been measured with the current sensor SCT-013 CT 100A and 9 V AC/AC step-down transformer connected to the Arduino Nano development board. Real power, apparent power and power factor values have been calculated by using measured current, voltage values and phase angle. These measured and calculated values have been sent to the ESP8266 NodeMCU development board by Software Serial technique. The ESP8266 provides HTML based user interface to computers and mobile devices connected to the CIoT network via the TCP/IP protocol. An access point has been used the WiFi connection. The user interface is displayed via the web browser of the devices with TCP/IP protocol. Four buttons on the user interface control the four relays connected to the CIoT network. Experimental studies show that the designed system could be used in general purpose applications such as energy monitoring in smart home systems.

Determination of Production Defects in Iron and Steel Sector by Data Mining 用数据挖掘方法确定钢铁生产缺陷
Ismail Burak Akinci, Filiz Ersoz
The studies related to the production industry are limited in the world and in our country. Especially in iron and steel sector, quality levels of different types of products need to be monitored. The studies show that with the emphasis on the quality levels of iron and steel products, the product life span is prolonged, and price and sales superiority is provided in the products. Accordingly, the market value of the products increases and there is a minimum loss of product. The primary purpose of the enterprises that realize the importance of quality work and improvements is to support quality production by preventing or reducing defects in production. Therefore, scientific studies in this sector should be focused on. Data mining and techniques, which is one of the scientific methods in this sector, have been used effectively in institutional and large enterprises. Data mining makes a significant contribution to business managers and includes the processes of finding and modeling meaningful relationships among the meaningless large data stacks in the enterprise. At this point, it is possible to define data mining as a set of techniques and concepts that generate new information for decision-making processes. In this study, firstly the data mining process is defined, data mining studies applied to certain quality improvement problems in manufacturing sector are examined and the optimization of process and quality parameters from quality improvement problems is emphasized. In the application part, data mining techniques are used to determine the variables and levels that cause production defects in an industrial enterprise. To achieve this aim, K-Means algorithm, which is one of the multivariate statistical methods, was examined by clustering analysis and the results obtained were supported by discriminant analysis. As a result of the analyzes, the products produced by the industrial enterprise were classified according to the production defects.
国内外对生产行业的相关研究都比较有限。特别是在钢铁行业,需要监测不同类型产品的质量水平。研究表明,重视钢铁产品的质量水平,可以延长产品寿命,并在产品上提供价格和销售优势。因此,产品的市场价值增加,产品损失最小。认识到质量工作和改进的重要性的企业的首要目的是通过防止或减少生产中的缺陷来支持质量生产。因此,这方面的科学研究应该得到重视。数据挖掘技术作为该领域的科学方法之一,已经在机构和大型企业中得到了有效的应用。数据挖掘为业务管理人员做出了重大贡献,它包括在企业中无意义的大型数据堆栈之间查找和建模有意义的关系的过程。此时,可以将数据挖掘定义为一组为决策过程生成新信息的技术和概念。本文首先对数据挖掘过程进行了定义,对数据挖掘在制造业质量改进问题中的应用进行了研究,并着重从质量改进问题中优化工艺和质量参数。在应用部分,利用数据挖掘技术确定导致工业企业生产缺陷的变量和层次。为此,采用聚类分析对多元统计方法之一的K-Means算法进行检验,并对所得结果进行判别分析。通过分析,对工业企业生产的产品进行了缺陷分类。

Developing Fast Techniques for Periodicity Analysis of Time Series 时间序列周期分析快速技术的发展
Muneera Yousif Yaqoob MOHAMMED, Mete Celik
The periodicity analysis of time series is the analysis of a set of measurements recorded for one or more variables arranged over time. Periodicity mining can be used in many application domains such as meteorology, astronomy, and econometrics. The techniques developed to find the periodicity are based on Fourier transform (FT), wavelet transform (WT), and dynamic time warping (DTW). Although the DTW performs well for periodicity analysis of time series, it is computationally complex. This study proposes two new algorithms which are formed by combining fast Fourier transform (FFT) with dynamic time warping (FFT-DTW) and wavelet transform with dynamic time warping (WT-DTW). The performances of the proposed algorithms were evaluated on real and synthetic datasets and the results are promising.
时间序列的周期性分析是对随时间排列的一个或多个变量记录的一组测量结果的分析。周期性挖掘可用于许多应用领域,如气象学、天文学和计量经济学。基于傅里叶变换(FT)、小波变换(WT)和动态时间规整(DTW)的周期性发现技术已经发展起来。虽然DTW对时间序列的周期性分析有很好的效果,但计算上比较复杂。本文提出了将快速傅里叶变换(FFT)与动态时间规整(FFT- dtw)和小波变换与动态时间规整(WT-DTW)相结合形成的两种新算法。在真实数据集和合成数据集上对所提算法的性能进行了评价,结果令人满意。

Detection and Analysis of Attacks Against Web Services by the SQL Injection Method 基于SQL注入的Web服务攻击检测与分析
Ilker Kara, M. Aydos
SQL injection is a security vulnerability resulting from unauthorized access to the victim database and services by attackers. Harmful codes can be injected into the victim database, all information in the database can be accessed or the database can be deleted completely and rendered unusable by using the SQL injection method. SQL injection attacks are a simple and effective method, used frequently in hacking attacks against Web services. Despite all measures taken, SQL injection attacks continue to increase. The academic studies in this field are usually theoretical, having limited practical aspects. In this study, an SQL injection attack case against a web service was examined in detail. The study aims to evaluate the SQL injection attacks in practice.
SQL注入是由于攻击者未经授权访问受害数据库和服务而导致的安全漏洞。使用SQL注入方法可以将有害代码注入受害数据库,也可以访问数据库中的所有信息,或者完全删除数据库,使其无法使用。SQL注入攻击是一种简单而有效的方法,经常用于针对Web服务的黑客攻击。尽管采取了各种措施,但SQL注入攻击仍在增加。该领域的学术研究通常是理论性的,实践方面有限。在本研究中,详细研究了针对web服务的SQL注入攻击案例。本研究旨在对SQL注入攻击进行实际评估。

Geofencing on the Real-Time GPS Tracking System and Improving GPS Accuracy with Moving Average, Kalman Filter and Logistic Regression Analysis GPS实时跟踪系统的地理围栏及移动平均、卡尔曼滤波和Logistic回归分析提高GPS精度
Zeynep Özdemir, Bulent Tugrul
People throughout history have wondered their position on the world. This led to the development of Global Navigation Satellite Systems (GNSS). The most widely used is the GPS (Global Positioning System) technology. Signals emitted from GPS satellites. Calculates your own location by detecting GPS receivers on earth. The GPS data obtained in this study was sent to a remote server via GSM and GPRS and turned into a real-time tracking system. The location of the GPS device can be monitored instantly by observing the application map screen from devices such as computer and phone. This monitored location has a certain delay considering the factors such as the arrival time of the GPS data to the device and the time the device connects to the internet. The system operates with a delay of 4 - 5 seconds. In addition, the Geofence field is used to alert the device when it moves away from a specified location. As the Geofence area, a predetermined polygon on the map can be used or the polygon area drawn during the application can be used as Geofence. On the application screen, an audible warning is given when leaving the Geofence area. GPS does not always show the exact correct position; it has a certain margin of error. Many factors affect this margin of error. This causes the application to give false alarms and operate with the wrong location. In order to reduce this error, the error rate was tried to be reduced by using Kalman filter, logistic regression analysis and moving average filter. Normally the error margin of up to 15 meters is considerably reduced by these filters.
纵观历史,人们都想知道自己在世界上的地位。这导致了全球导航卫星系统(GNSS)的发展。使用最广泛的是GPS(全球定位系统)技术。GPS卫星发出的信号。通过探测地球上的GPS接收器来计算你自己的位置。本研究获得的GPS数据通过GSM和GPRS发送到远程服务器,形成实时跟踪系统。通过从计算机和电话等设备观察应用程序地图屏幕,可以立即监视GPS设备的位置。考虑到GPS数据到达设备的时间和设备连接到互联网的时间等因素,这个被监控的位置有一定的延迟。系统运行时的延迟为4 - 5秒。此外,gefence字段用于在设备离开指定位置时发出警报。Geofence区域可以使用地图上预定的多边形,也可以使用应用过程中绘制的多边形区域作为Geofence区域。在应用程序屏幕上,当离开地理围栏区域时,会发出声音警告。GPS并不总是显示精确的正确位置;它有一定的误差范围。许多因素会影响这个误差范围。这将导致应用程序给出假警报并在错误的位置上操作。为了减小这一误差,尝试使用卡尔曼滤波、逻辑回归分析和移动平均滤波来降低错误率。通常情况下,这些滤波器可大大减少高达15米的误差范围。

Optimum Design of PID Controller in AVR System Using Harris Hawks Optimization 基于Harris Hawks优化算法的AVR系统PID控制器优化设计
Serdar Ekinci, B. Hekimoğlu, Erdal Eker
Automatic voltage regulator (AVR) is an important device that regulates and controls the terminal voltage of the synchronous generator in power systems. Proportional-integral-derivative (PID) controllers are generally preferred to improve the stability performance and robustness profile of the AVR system. This paper presents a new parameter tuning approach based on Harris hawks optimization (HHO) to determine PID controller gains in the AVR system. The effectiveness of the proposed HHO tuned PID controller has been confirmed by extensive simulation studies. Compared to bio-geography-based optimization (BBO), the new HHO tuning method has better control system performance and robustness.

Estimating GSR by Empirical models: Case Study for İskenderun, Turkey 实证模型估算GSR:以土耳其İskenderun为例
I. Mert
In this study, the predictability of Global Solar Radiation (GSR) data is investigated for Iskenderun region, which has a rich source of solar energy. Four different models were used to estimate GSR using current data. Linear, quadratic and exponential relationships were preferred among the parameters for absolute and stable results of these models. The empirical coefficients a, b and c of the models were calculated to estimate the average solar radiation of the region. The correlations between the obtained values from models and the current meteorological values were found to be consistent. As a result, a stable and reasonable approach was obtained for the estimation of GSR coming to the horizontal plane for the region.

As a result, a stable and reasonable approach was obtained for the estimation of GSR coming to the horizontal plane for the region.","PeriodicalId":169791,"journal":{"name":"2019 3rd International Symposium on Multidisciplinary Studies and Innovative Technologies (ISMSIT)","volume":"249 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128557977","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}

Bebek Gazını Gidermeye Yardımcı Elektronik Bel Bandı
Musa Bute
In this study, an electronic waistband is proposed for infants to relieve their gases. As it is known that, when newborn babies are growing up especially, in the duration of first six months they face intestinal gas pain and restlessness. To eliminate this restlessness not only for infants but also for their parents an electronic waistband with thermal fabric body is designed. This waistband has a thermal fabric body provided with vibration modules that are provided with cables. An electronic part comprises a power supply and isolates the main part from the thermal fabric body. Moreover, the thermal fabric body is provided with multiple fabric layers and the vibration modules comprise pockets to be placed. In addition, rechargeable battery set-up is developed in the battery compartment.
在这项研究中,提出了一种电子腰带,用于婴儿排便。众所周知,当新生儿特别是在成长过程中,在最初的六个月里,他们会面临肠气疼痛和不安。为了消除这种不安,不仅为婴儿,也为他们的父母设计了一种热感织物体的电子腰带。该腰带具有具有振动模块的热织物体,振动模块配有电缆。一种电子部件包括电源,并将主要部件与热织物本体隔离。并且,所述热织物本体具有多个织物层,所述振动模块包含要放置的口袋。此外,在电池舱中开发了可充电电池设置。
