The rapid growth of social networks indeed triggers an increase in malicious activities, including the spread of false information, the creation of fake accounts, spamming, and malware distribution. However, developing a detection system that can identify accounts precisely becomes quite challenging. In this paper, we present a study related to the detection of malicious accounts on Twitter users from Indonesia. Our study objective is to propose a simple feature set to detect malicious accounts using only a few metadata and the tweet content itself from Twitter. We divided the classification level into three: account level classification, tweet level classification, and combination of account and tweet level classification. To get the classification results, we applied some popular machine learning algorithms such as Random Forest, Decision Tree, AdaBoost Classifier, Neural Network, and Logistic Regression to each classification level. The results show that Random Forest achieved high classification accuracy (AUC >80%) in each classification level using our proposed feature set.
社交网络的快速发展确实引发了恶意活动的增加,包括虚假信息的传播、虚假账户的创建、垃圾邮件和恶意软件的分发。然而,开发一种能够准确识别账户的检测系统变得相当具有挑战性。在本文中,我们提出了一项有关检测来自印度尼西亚的Twitter用户的恶意帐户的研究。我们的研究目标是提出一个简单的功能集,仅使用少量元数据和Twitter的tweet内容本身来检测恶意帐户。我们将分类级别分为三类:账户级分类、推文级分类、账户与推文级结合分类。为了得到分类结果,我们将随机森林、决策树、AdaBoost分类器、神经网络和逻辑回归等一些流行的机器学习算法应用于每个分类层次。结果表明,使用我们提出的特征集,随机森林在每个分类级别上都取得了较高的分类准确率(AUC)。

This study examines the influence of homophily, expertise, and emotional attachment to the popularity of vloggers and ultimately examines the effect of emotional attachment, vlogger popularity, and expertise on the purchase intention of recommended beauty products by focusing on beauty vlogger Tasya Farasya. Homophily itself is divided into four dimensions including attitude, background, morals, and appearance. This study uses a descriptive research design conducted in a single-cross sectional through the distribution of questionnaires online to respondents. The target respondents of this study were Indonesian women aged 15 years and over and had watched the YouTube video of Tasya Farasya (n = 430). The data obtained processed using the statistical method of Structural Equation Modeling (SEM) using LISREL 8.80 software. The results of this research showed that almost all dimensions of homophily (attitude, values, appearance) are significantly have a positive impact the emotional attachment. On the other hand, all dimensions of homophily does not have a significant positive impact on vloggers’ popularity. Then, emotional attachment and expertise also found have a significant positive impact to vloggers’ popularity. In last, researcher found that emotional attachment and expertise are significantly have a positive impact the purchase intentions of viewers while vloggers’ popularity does not.
本研究以美妆视频博主Tasya Farasya为研究对象,考察同质性、专业知识和情感依恋对视频博主受欢迎程度的影响,并最终考察情感依恋、视频博主受欢迎程度和专业知识对推荐美妆产品购买意愿的影响。同质性本身分为态度、背景、道德、外表四个维度。本研究采用描述性研究设计,通过在线向受访者分发问卷,在单一横截面进行。本研究的目标调查对象为观看过Tasya Farasya YouTube视频的15岁及以上的印尼女性(n = 430)。所得数据采用LISREL 8.80软件对结构方程建模(SEM)的统计方法进行处理。本研究结果显示,同质性的几乎所有维度(态度、价值观、外貌)都对情感依恋产生显著的正向影响。另一方面,所有维度的同质性对视频博主的受欢迎程度并没有显著的积极影响。此外,情感依恋和专业知识也对视频博主的受欢迎程度产生了显著的积极影响。最后,研究者发现情感依恋和专业知识对观众的购买意愿有显著的正向影响,而视频博主的受欢迎程度对观众的购买意愿没有显著的正向影响。

Indonesia is one of the largest swallow nest producers, supported by its natural condition as the original habitat of swiftlets. The selling price of unstable products and the lack of information about the prices of products exported to the general public are the problems faced. The absence of a benchmark or source of certain product prices that cause uncertainty in determining product prices. For this reason, the prediction system is created by applying the Holt’s Double Exponential Smoothing (DES) method, because this smoothing method can overcome time series data that has trend patterns. The prediction system provides a graph of the price movements of export products and price predictions for the following month. Based on testing that has been done, the results obtained mean that the Absolute Presentation Error (MAPE) is very good at 0.20%.
印度尼西亚是最大的燕窝生产国之一,这得益于其作为金丝燕原始栖息地的自然条件。面临的问题是产品的销售价格不稳定,以及出口到一般公众的产品价格信息缺乏。缺乏某些产品价格的基准或来源,从而导致确定产品价格的不确定性。因此,采用霍尔特双指数平滑(Holt’s Double Exponential Smoothing, DES)方法创建预测系统,因为这种平滑方法可以克服具有趋势模式的时间序列数据。预测系统提供出口产品价格变动的图表和下个月的价格预测。根据已经完成的测试,获得的结果意味着绝对呈现误差(MAPE)在0.20%的情况下非常好。

Wind speed prediction is needed in various sectors, such as in industry. However, the weather conditions change all the time, so it is not easy to predict. The wind that blows is influenced by several climatic weather factors such as humidity and rainfall. Also, wind speed patterns change when there is a global climate change, El Nino. Therefore this research involved the element in predicting wind patterns one week ahead. Recurrent Neural Networks (RNN) and Long-short Term Memory (LSTM) methods are used for sequential data processing, such as climate data. Climate data for ten years used were wind speed, humidity, and rainfall provided by Meteorological, Climatological, and Geophysical Agency (BMKG) of a weather observation station, while Southern Oscillation Index (SOI), was obtained from the Australian Bureau of Meteorology (ABM). Data need to be pre-processed to solve missing data. Moreover, all variables were normalized and segmentation by overlapping to avoid data discontinuity. The results showed that the use of the amount of data, learning rate, epoch, and selection of the right optimization model could give good accuracy. The purpose of the proper configuration has a good performance, with accuracy reaching 88.34%. The results showed that the use of SOI factors improved correctness from 74.75% without SOI. The results also show that the model Adaptive Moment Estimation (Adam) provides better accuracy than the model Stochastic Gradient Descent (SGD), which gives an accuracy of only 71.84%. Meanwhile, the study also examined the effect of the learning rate and composition of training data and test data. The best accuracy is shown for the learning rate of 0.020 and 80:20% of training and test data comparison.
风速预测在工业等各个领域都是需要的。然而,天气状况一直在变化,所以不容易预测。吹起的风受几个气候天气因素的影响,如湿度和降雨量。此外,当全球气候发生变化,即厄尔尼诺现象时,风速模式也会发生变化。因此,这项研究涉及到提前一周预测风向的因素。循环神经网络(RNN)和长短期记忆(LSTM)方法用于时序数据处理,如气候数据。10年的气候资料是由气象观测站的气象、气候和地球物理局(BMKG)提供的风速、湿度和降雨量,而南方涛动指数(SOI)是由澳大利亚气象局(ABM)提供的。需要对数据进行预处理以解决丢失的数据。对所有变量进行归一化和重叠分割,避免数据不连续。结果表明,利用数据量、学习率、历元和选择合适的优化模型可以获得较好的准确率。合理配置的目的具有良好的性能,准确率达到88.34%。结果表明,在没有SOI的情况下,使用SOI因子可以将正确率提高74.75%。结果还表明,自适应矩估计(Adam)模型比随机梯度下降(SGD)模型具有更好的精度,其精度仅为71.84%。同时,研究还考察了训练数据和测试数据的学习率和组成的影响。训练数据和测试数据比较,学习率为0.020%和80:20%时准确率最高。

Addressing different learner’s characteristics and needs is a critical issue in the process of learning. The advent of adaptive e-Learning technology has made it possible to tailor learning materials for different learner characteristics including learning styles. Delivering matching learning objects and strategies through an adaptive e-Learning system is believed to have a profound impact on learner’s learning performance. A body of research has offered various personalization strategies including learning object mapping according to learning styles. This paper focused on exploring how the learning objects are mapped to Felder-Silverman learning styles and the effect of implementing such approach. In this paper, 15 relevant publications were reviewed in order to gain some insights into the implementation of learning styles-based personalization. Based on the insights found this study proposed a conceptual learning object mapping and personalization strategies. The findings and recommendations of this study can be utilized as the basis to build an adaptive e-Learning system based on Felder-Silverman Learning Style Model (FSLSM).

The trend of internet of things (IoT) makes the cloud less effective because networked control systems need low latency while cloud have high latency for processing data from sensors and devices. In that kind of situation, fog computing is introduced as the complement of cloud computing. However, unlike cloud services, fog services are limited to certain geographical area. As a consequence, fog services handover is needed in order to accommodate user’s mobility. This paper is focusing on microservices handover that follows user’s movement. The microservices installed in the current fog node are sent to another service coverage of a new fog node for continuing the same service to the users. Fog node contains a docker that runs MySQL, python script, and busybox services. When it comes to handover, docker will freeze current session and convert it to a checkpoint file. The file is created by taking a snapshot of the container, which consists of processes in memory, volume or image. The file will be sent by using secure shell (SSH) or file transfer protocol (FTP). At the destination fog node, the file will be processed in order to resume the service. The results show that delay of SSH is always higher than FTP in all experiments, in which the largest delays are 484.026 seconds for SSH protocol and 146.41 seconds for FTP protocols. As for checkpoint and restore process, those delays tend to be similar with respect to both SSH and FTP protocols but they are still affected by the size of snapshot and checkpoint file.
物联网(IoT)的趋势使得云的效率降低,因为网络控制系统需要低延迟,而云在处理来自传感器和设备的数据时具有高延迟。在这种情况下,雾计算作为云计算的补充而被引入。然而,与云服务不同,雾服务仅限于特定的地理区域。因此,为了适应用户的移动性,需要雾服务切换。本文关注的是跟随用户移动的微服务切换。安装在当前雾节点中的微服务被发送到新雾节点的另一个服务覆盖,以继续向用户提供相同的服务。Fog节点包含一个docker,运行MySQL、python脚本和busybox服务。在切换时,docker将冻结当前会话并将其转换为检查点文件。该文件是通过获取容器的快照创建的,容器由内存、卷或映像中的进程组成。文件将通过SSH (secure shell)或FTP(文件传输协议)发送。在目标雾节点上,将处理该文件以恢复服务。结果表明,在所有实验中,SSH协议的延迟始终高于FTP协议,其中SSH协议的最大延迟为484.026秒,FTP协议的最大延迟为146.41秒。至于检查点和恢复过程,这些延迟对于SSH和FTP协议来说都是类似的,但它们仍然受到快照和检查点文件大小的影响。

The application of microchip technology has the potential to detect early health aspects. The mixing process in the medical laboratory examination with a blood check is important to determine the overall health condition and provide information on the disease suffered and also determine the treatment carried out or the next stage. This paper aims to study the simulation of microfluidic mixer devices based on flattening channels for blood mixing applications. The finite element analysis is used to study the effect of flattening channel geometry related to the microfluidic mixer performance. The results show that the mixing index above 0.98 is obtained which means the fluid was mixed homogenously. As a consequence, rapid and efficient mixing remains a challenging task within the design and development of micromixers. Furthermore, from the Reynolds number variations, it revealed that the mixing index increase when the Reynolds number increase.
微芯片技术的应用有可能发现早期健康问题。医学实验室检查与血液检查的混合过程对于确定总体健康状况和提供所患疾病的信息以及确定所进行的治疗或下一阶段非常重要。本文旨在研究用于血液混合应用的基于平坦通道的微流控混合器装置的仿真。采用有限元方法研究了平坦通道几何形状对微流控混合器性能的影响。结果表明,混合指数在0.98以上,表明流体混合均匀。因此,快速有效的混合仍然是微混合器设计和开发中的一项具有挑战性的任务。此外,从雷诺数的变化可以看出,随着雷诺数的增加,混合指数增加。

Furthermore, from the Reynolds number variations, it revealed that the mixing index increase when the Reynolds number increase.","PeriodicalId":211983,"journal":{"name":"2020 3rd International Conference on Computer and Informatics Engineering (IC2IE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121978498","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}

Lip motion recognition is a technique for interpreting visual data that focuses on the mouth area and aims to recognize lip movement. The development of lip motion recognition is expected to be used to develop communication tools with deaf people and to automate the speech-to-text process visually. In the Indonesian language, the existence of vowel phonemes is needed to produce sounds so that words and sentences in the Indonesian language can be formed. This paper proposes a model that can recognize Indonesian vowel phonemes (/a/, /i/, /u/, /e/, and /o/) in lip movements. We proposed a model that uses 3D Convolutional Neural Networks. The data in this paper were processed by resizing into 112x56 pixel resolution then, proceed to the data augmentation by reversing the data horizontally and add blur to the data. The results of the testing of the vowel phoneme recognition model on lip motion show the highest accuracy rate of 84%.
唇动识别是一种解释视觉数据的技术,主要集中在嘴部区域,旨在识别唇动。唇动识别的发展有望用于开发与聋人的交流工具,并实现语音到文本的视觉自动化过程。在印尼语中,元音音素的存在是产生声音的必要条件,印尼语中的单词和句子才能形成。本文提出了一个可以识别印尼语元音音素(/a/, /i/, /u/, /e/和/o/)的唇形模型。我们提出了一个使用三维卷积神经网络的模型。本文将数据调整为112x56像素分辨率,然后进行数据增强,将数据水平反转,并对数据进行模糊处理。实验结果表明,基于唇动的元音音素识别模型准确率最高,达到84%。
