Rapid technological development at this time is not only recognized by humans, now sensors embedded in smartphones can also recognize human activity using an accelerometer sensor and gyroscope sensor that has been embedded in it by producing hundreds or even thousands of records. accelerometer sensor and gyroscope sensor is one feature that serves to read the rate of change of acceleration from a smartphone but has a different function and requires data mining methods to group based on that output. Data mining methods that have better performance than other methods are Support Vector Machine (SVM) but are sensitive to parameter settings and sample training that cause undefined performance to overcome the shortcomings of the Support Vector Machine method by performing SVM ensembles, which are ensemble used is bagging. This research proposes the application of svm ensemble technique to perform human activity classification based on accelerometer sensor and gyroscope sensor. The results show that the best performance of SVM ensemble technique when comparing datasets with 70% training data and 30% test data with 99.1% accuracy, sensitivity 99.6% and specificity 98.7%.
加速度传感器和陀螺仪传感器是用于读取智能手机加速度变化率的一种功能,但具有不同的功能,需要数据挖掘方法根据该输出进行分组。与其他方法相比,支持向量机(SVM)是性能更好的数据挖掘方法,但它对参数设置和样本训练很敏感,导致性能不确定,为了克服支持向量机方法的缺点,需要进行 SVM 集合,这种集合就是袋集。本研究提出应用 SVM 集合技术来执行基于加速度传感器和陀螺仪传感器的人体活动分类。结果表明,在对 70% 训练数据和 30% 测试数据的数据集进行比较时,SVM 集合技术的准确率为 99.1%,灵敏度为 99.6%,特异性为 98.7%,表现最佳。

The high growth of news document emerging a new problem when the news website does not provide downloading service. This paper describes an approach of providing title, publication date, author, clean text article, and URL address of news article from HTML page of three news web-sites, i.e., Detik, Tribunnews, and Liputan6 without manually copy and paste process. This approach consists of three steps, i.e.: analyzing news website structure, constructing pattern of Regex and implementing the patterns as a set of rule in web scraping. Based on the experiment, each news web site used their own pattern for article link, article title, article author, and publication date of article. Special for extracting a clean text of news article phase, there were two kinds of pattern i.e.: content pattern (for extracting original text article of news) and filter pattern (for eliminating non-news elements). In these three-news website, the non-news elements consist of text advertisement, video advertisement, link, image, and script with different pattern for every website. After generated all necessary patterns and implemented these patterns as a set of rules, the web scraping module produced very good results of news article extraction on Detik and Tribunnews that was presented by recall = 1, precision = 1 and F-Measure =100% while Liputan6 had a little bit lower i.e., recall =0.95, precision =0.95, and F-Measure =95%. It is found that this approach is a simple and strait forward way to extract news article which consists of title, publication date, author, news article, and the URL address of news article.
新闻文档的高速增长在新闻网站不提供下载服务的情况下,出现了新的问题。本文介绍了一种从Detik、Tribunnews和liputan 3个新闻网站的HTML页面中提供新闻文章的标题、发布日期、作者、纯文本文章和URL地址的方法,无需手动复制粘贴过程。该方法包括三个步骤,即分析新闻网站结构,构建正则表达式模式,并将模式作为一套规则实现在网页抓取中。在实验的基础上,每个新闻网站对文章链接、文章标题、文章作者和文章发布日期都使用了自己的模式。特别是在提取新闻文章的纯文本阶段,有两种模式,即内容模式(用于提取新闻的原始文本文章)和过滤模式(用于去除非新闻元素)。在这三个新闻网站中,非新闻元素包括文字广告、视频广告、链接、图片和脚本,每个网站都有不同的模式。在生成所有需要的模式并将这些模式作为一组规则实现之后,web抓取模块在Detik和Tribunnews上产生了非常好的新闻文章提取结果,召回率=1,精度=1,F-Measure =100%,而Liputan6的结果稍低,召回率=0.95,精度=0.95,F-Measure =95%。结果表明,该方法是一种简单明了的提取新闻文章的方法,它由标题、发布日期、作者、新闻文章和新闻文章的URL地址组成。

The Golay codes are widely used Error Correction Codes (ECCs) that are used to recognize and correct errors in digital systems. This paper proposes an efficient architecture for hardware implementation of Golay code encoder. The proposed architecture has three important units: 1) data unit, 2) control unit and 3) conversion unit. These units are carefully designed such that the developed architecture can work for a message with ‘0’ and ‘1’ Most Significant (MS) bits. The performance of the developed encoder architecture is verified using FPGA devices. The results demonstrate that the developed encoder architecture provides a promising advantage compared to other encoder architectures for Golay codes.

Geothermal utilization in Indonesia is mostly for electricity generation. Electricity consumption has increased while geothermal production has not increased, so it is necessary to develop geothermal wells. One of the efforts is the prediction of well behavior so that the well performance can be known which a need for well development is. To predict the behavior of geothermal wells temperature prediction (T) and pressure (P) with location parameters (x and y), well depth (z) injection flow rate (qinj) and injection temperature (Tinj) using the Artificial Neural Network (ANN) method. The first is the generation of well production models, M-1, M-2 and M-3, each model has 6 wells. Data is generated during one year of production and data separation is carried out, i.e. data for 11 months is used as ANN training data and data for the last 1 month is used as test data. The results of the prediction with ANN will be compared with the test data. Calculation of errors between the predicted results and the test data on M-1 is 0.0251 for temperature (T) and 0.0303 for pressure (P), while the MSE value is 0.00378. At M-2 is 0.0283 for temperature (T) and 0.0468 for pressure (P), while the MSE value is 0.000795. At M-3 is 0.0445 for temperature (T) and 0.0566 for pressure (P), while the MSE value is 0.0121. Based on the results obtained the error value and MSE are relatively small, so ANN can be used to predict the behavior of geothermal wells. Then the variation in the number of hidden layers is done. H-15 has the best error value and MSE, while h-50 has the best regression value (R).
印度尼西亚的地热利用主要用于发电。用电量增加而地热产量没有增加,开发地热井是必要的。其中一项工作是预测井的动态,以便了解哪些井需要开发。利用人工神经网络(ANN)方法,利用位置参数(x和y)、井深(z)、注入流量(qinj)和注入温度(Tinj)预测地热井温度(T)和压力(P)的变化规律。首先是M-1、M-2、M-3井生产模型的生成,每个模型有6口井。数据生成时间为生产1年,并进行数据分离,即使用11个月的数据作为ANN训练数据,使用最近1个月的数据作为测试数据。用人工神经网络预测的结果将与测试数据进行比较。M-1上的预测结果与试验数据计算误差分别为温度(T) 0.0251和压力(P) 0.0303, MSE值为0.00378。在M-2时,温度(T)为0.0283,压力(P)为0.0468,而MSE值为0.000795。M-3处温度(T)为0.0445,压力(P)为0.0566,MSE值为0.0121。结果表明,人工神经网络的误差值和均方差都比较小,可以用于地热井的动态预测。然后完成隐藏层数的变化。H-15的误差值和MSE最好,h-50的回归值R最好。

H-15 has the best error value and MSE, while h-50 has the best regression value (R).","PeriodicalId":424909,"journal":{"name":"2018 2nd East Indonesia Conference on Computer and Information Technology (EIConCIT)","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116172331","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}

Transmittance and reflectance modes are the two most common technique used for investigating liquid psychochemical properties based on optical spectra. In the case of honey characterization, this research performed to show a comparison between both modes to measure honey’s Total Soluble Solids and pH based on the Vis-NIR hyperspectral imaging system. The system consists of Specim FX10 hyperspectral camera with 448 bands (400-1000nm), three 200 W halogen lamps, a light diffuser, a motor slider, and a PC. Then, a Partial Least Square Regression (PLSR) algorithm applied to predict measured values based on the acquired transmittance and reflectance spectrum. Performance of each technique tested by tenfold Cross Validation, which randomly grouping the dataset into ten partitions. Samples is prepared from 28 different honey types with varied colors, placed in 5 cm diameter Petri dishes at 10 ml volume. Performance of each technique measured by R2 and a Root Mean Square Percentage Error (RMSPE) score. Transmittance mode results in R2 of 0.93 and 0.80, RMSPE of 1.06% and 5.36% for total soluble solid content and pH measurement. For similar measured properties, reflectance mode results in R2 of 0.94 and 0.82, RMSPE of1.01% and 5.23%. In this research, reflectance mode performs slightly better than transmittance mode in the measurement of Total Soluble Solids and pH in honey samples.
透射和反射模式是基于光谱研究液体心理化学性质最常用的两种技术。以蜂蜜表征为例,本研究展示了基于Vis-NIR高光谱成像系统测量蜂蜜总可溶性固形物和pH值的两种模式之间的比较。该系统由448个波段(400-1000nm)的specm FX10高光谱相机、3个200w卤素灯、一个漫射器、一个电机滑块和一台PC组成。然后,采用偏最小二乘回归(PLSR)算法,根据获取的透射光谱和反射光谱预测测量值。每种技术的性能通过十次交叉验证进行测试,该交叉验证将数据集随机分组为十个分区。样品由28种不同颜色的蜂蜜制成,放置在直径5厘米的培养皿中,体积为10毫升。通过R2和均方根百分比误差(RMSPE)评分来衡量每种技术的性能。透过率模式测定的总可溶性固形物含量和pH值的R2分别为0.93和0.80,RMSPE分别为1.06%和5.36%。对于类似的测量性质,反射模式的结果R2分别为0.94和0.82,RMSPE分别为1.01%和5.23%。在本研究中,反射模式比透射模式在测量蜂蜜样品中的总可溶性固体和pH值时表现略好。

Prior to traveling, one of the most important things to pay attention to is to determine the travel route, especially the shortest path to be taken. In this study, the method used to determine the shortest route is the conventional method and the Heuristic method. These two methods will be compared to find out methods which can provide the best result. For conventional methods, the authors use the Floyd- Warshall algorithm whereas for the Heuristic method, the greedy algorithm is employed. The Floyd-Warshall algorithm takes into account all possible routes so that there are some routes are displayed while the greedy algorithm checks every node that is passed to select the shortest route (Local Optimum) so that the time needed in searching is faster. Based on the conducted testing, the final result obtained is the Floyd- Warshall algorithm provides a better solution, namely the mileage was 22.7 km and the greedy algorithm covered a mileage of 24.8 km. This result indicated that a longer time is required because it takes the distance to all points into account.
在旅行之前,要注意的最重要的事情之一是确定旅行路线,特别是要走的最短路径。在本研究中,确定最短路线的方法是常规方法和启发式方法。将这两种方法进行比较,找出能够提供最佳结果的方法。对于传统方法,作者采用Floyd- Warshall算法,而对于启发式方法,作者采用贪心算法。Floyd-Warshall算法考虑了所有可能的路由,因此会显示一些路由,而贪心算法会检查经过的每个节点,选择最短的路由(局部最优),从而使搜索所需的时间更快。根据所进行的测试,最终得到的结果是Floyd- Warshall算法提供了更好的解决方案,即里程为22.7 km,贪婪算法覆盖的里程为24.8 km。这个结果表明,由于考虑到所有点的距离,需要更长的时间。
