Person tracking with non-overlapping multiple cameras 使用不重叠的多个摄像头进行人员跟踪
S. K. Sonbhadra, Sonali Agarwal, M. Syafrullah, K. Adiyarta
Monitoring and tracking of any target in a surveillance system is an important task. When these targets are human then this problem comes under person identification and tracking. At present, large scale smart video surveillance system is an essential component for any commercial or public campus. Since field of view (FOV) of a camera is limited; for large area monitoring, multiple cameras are needed at different locations. This paper proposes a novel model for tracking a person under multiple non-overlapping cameras. It builds the reference signature of the person at the beginning of the tracking system to match with the upcoming signatures captured by other cameras within the specified area of observation with the help of trained support vector machine (SVM) between two cameras. For experiments, wide area re-identification dataset (WARD) and a real-time scenario have been used with color, shape and texture features for person's re-identification.
在监视系统中,对任何目标的监视和跟踪都是一项重要的任务。当这些目标是人类时,这个问题就涉及到人的识别和跟踪。目前,大型智能视频监控系统是任何商业或公共校园必不可少的组成部分。由于相机的视野(FOV)是有限的;对于大面积的监控,需要在不同的位置安装多个摄像机。本文提出了一种在多个不重叠摄像机下跟踪一个人的新模型。它在跟踪系统开始时建立人的参考签名,并借助两台相机之间训练好的支持向量机(SVM)与指定观察区域内其他相机捕捉到的即将到来的签名进行匹配。在实验中,利用广域再识别数据集(WARD)和具有颜色、形状和纹理特征的实时场景对人进行再识别。

Steady-state response feature extraction optimization to enhance electronic nose performance 提高电子鼻性能的稳态响应特征提取优化
D. K. Agustika, S. Hidayat, K. Triyana, D. Iliescu, M. Leeson
Feature extraction of electronic nose (e-nose) output response aims to reduce information redundancy so that the e-nose performance can be improved. The use of different sensor types and sample targets can affect the optimization of feature extraction. This research used six types of metal oxide sensors, TGS 813, 822, 825, 826, 2620, and 2611 in an e-nose system to detect three types of herbal drink. Five kinds of feature extraction methods on the original response curve in a steady-state response were used, namely, baseline difference, logarithmic difference, local normalization, global normalization, and global autoscaling. The results of feature extraction were fed into a Principal Component Analysis (PCA) system. As a result, global autoscaling and normalization had the highest total sum of the first and second principal components of 96.96%, followed by local normalization (90.18%), logarithm, and baseline difference (88.92% and 79.26%, respectively). The validation of PCA results was performed using a Backpropagation Neural Network (BPNN). The highest accuracy, 97.44%, was obtained from the global autoscaling method, followed by global normalization, local normalization, logarithm, and baseline difference, with an accuracy level of 94.87%, 92.31 %, 89.74%, and 82.05%, respectively. This demonstrates that the selection of the feature extraction method can affect the classification results and improve e-nose performance.
电子鼻输出响应特征提取的目的是减少信息冗余,从而提高电子鼻性能。不同传感器类型和样本目标的使用会影响特征提取的优化。本研究在电子鼻系统中使用TGS 813、822、825、826、2620和2611六种金属氧化物传感器检测三种草药饮料。采用基线差分法、对数差分法、局部归一化法、全局归一化法和全局自标度法对稳态响应的原始响应曲线进行特征提取。特征提取结果被送入主成分分析(PCA)系统。结果表明,全局自缩放和归一化的第一主成分和第二主成分的总和最高,为96.96%,其次是局部归一化(90.18%)、对数和基线差(分别为88.92%和79.26%)。使用反向传播神经网络(BPNN)对PCA结果进行验证。全局自标度法准确率最高,为97.44%,其次为全局归一化法、局部归一化法、对数法和基线差法,准确率分别为94.87%、92.31%、89.74%和82.05%。这说明特征提取方法的选择可以影响分类结果,提高电子鼻的性能。

Prototype Design of Mobile Application ‘Hydrolite’ for Hydroponics Marketplace 水培市场移动应用程序“Hydrolite”的原型设计
A. Permana, R. Taufiq, Salsabila Ramadhina
Hydroponics is one of the effective farming methods to apply in big cities because it does not require extensive agricultural land. In addition, hydroponic products are cleaner, higher quality and free from pesticides. However, the development of hydroponic products in Indonesia is relatively slow. One of the factors causing the slow development of hydroponic agribusiness is that online sales media for hydroponic products are still limited, especially android-based e-marketplace application. Hydrolite is present as an e-marketplace that specifically sells vegetables grown using the hydroponic method, and sells all the equipment needed to farm hydroponically. Hydrolite is a prototype e-marketplace application designed using the Marvelapp platform. Further, Marvelapp is one of the best prototyping tools to support application development on mobile devices.
水培法是一种适用于大城市的有效耕作方法,因为它不需要大量的农业用地。此外,水培产品更清洁,质量更高,不含农药。然而,印尼水培产品的发展相对缓慢。水培农业发展缓慢的原因之一是水培产品的在线销售媒体仍然有限,尤其是基于android的电子市场应用。Hydrolite是一个电子市场,专门销售使用水培方法种植的蔬菜,并销售水培种植所需的所有设备。Hydrolite是一个使用Marvelapp平台设计的电子市场应用程序原型。此外,Marvelapp是支持移动设备上应用程序开发的最佳原型工具之一。

Potential for Reducing CO2 Emissions in the Operation of Subcritical Power Plants into Supercritical 亚临界电厂转超临界运行中减少二氧化碳排放的潜力
Sunaryo, A. Putra, Arief Marwanto, Muhamad Haddin
The consumption of electricity that increase anytime also increases CO2 emissions in the air as a result of coal combustion flue gas at the power plant. The operation of supercritical boilers on the power plant will lead to higher thermal efficiency compared to subcritical boilers. Higher steam pressure boiler will increase the thermal efficiency and automatically reduce CO2 emissions due to a reduction in fuel consumption at the same boiler efficiency and heating value of coal. At 166.9 bar subcritical steam boiler thermal efficiency was 45.47 % and CO2 emissions were 602.2 tons while at supercritical pressure 240 bar, efficiency increased to 47.12 % with a reduction in CO2 emissions of 20.9 tons to 581.3 tons.
随时增加的电力消耗也增加了空气中的二氧化碳排放量,这是发电厂燃烧煤炭烟气的结果。超临界锅炉在电厂的运行将比亚临界锅炉产生更高的热效率。在相同的锅炉效率和煤的热值下,较高的蒸汽压力锅炉将提高热效率,并由于燃料消耗的减少而自动减少CO2的排放。在166.9 bar的亚临界压力下,锅炉热效率为45.47%,二氧化碳排放量为602.2吨;在超临界压力为240 bar时,锅炉热效率提高到47.12%,二氧化碳排放量减少20.9吨,为581.3吨。

Muhammad Nor Arif Sulaiman, T. Adiono
Digital image processing is a processing of digital frames using digital computation. Image processing has been used in many sectors such as military, biomedics, and in this paper, the authors will implement it in the civil aviation sector by introducing a new method to monitor an aviation navigation equipment. It can be used on all LED-based Built-in Monitor navigation equipment, despite it is a low-cost system. The image processing of this research is done by doing perspective correction and then continue with BLOB detection in a segmentation stage. The final result will be displayed on a web page. Compared to its predecessor, this method gives better flexibility which does not need to be electrically connected with monitored equipment and not limited to certain brands.

Kurniandha Sukma Yunastrian, Saiful Akbar, F. Arifiansyah
Spreadsheet is one of the tools that can be used to learn data analysis. Data analysis in spreadsheet can be done using formula. Spreadsheet tools can also be used for exams. For the assessment, there is a problem when the number of answers that need to be checked is large, that is it takes a long time to check all the answers. For this reason, an automatic grading system (autograder) that can evaluate formula in spreadsheet is needed. The method used in developing the autograder system is matching the answer key formula with the student's answer formula. The autograder system assesses the answer by calculating the similarity of the student's answer formula with the answer key formula. This paper explains how to build an autograder system that can evaluate the formula. At the end, an autograder system has been built successfully. It has been tested with 43 testcases and all of them are passed.

Implementation of Secure Work From Home System Based on Blockchain using NS3 Simulation 基于区块链的安全在家办公系统的NS3仿真实现
Mega Apriani, Diwandaru Rousstia, Fajar Achmad Rifai, R. Harwahyu, R. F. Sari
Work from Home (WFH) is an activity carrying out official duties, completing outputs, coordination, meetings, and other tasks from the residence of employees. Implement WFH many users use the zoom application has vulnerabilities. The network architecture used refers to the simple experiment network. In Secure WFH there are 3 offices connected through a router. Each client in each office is connected to the router via a Virtual Private Network (VPN) on a peer-to-peer (P2P). That architecture has 18 nodes that will be simulated. Secure WFH simulation with blockchain combines secure WFH with a bitcoin code simulator from Arthur Gervais's. Implementation of blockchain on secure WFH can increase security but the resulting speed decreases. The decrease in speed when implementing secure WFH is due to the generate block process and the verification process.
在家办公(Work from Home, WFH)是一种在员工住所执行公务、完成产出、协调、会议等任务的活动。实现WFH的许多用户使用的缩放应用程序存在漏洞。使用的网络架构为简单的实验网络。在安全WFH中,有3个办公室通过路由器连接。每个办公室的每个客户端都通过点对点的VPN (Virtual Private Network)连接到路由器。该架构有18个节点将被模拟。区块链的安全WFH模拟将安全WFH与Arthur Gervais的比特币代码模拟器结合在一起。在安全WFH上实施区块链可以提高安全性,但导致速度降低。在实现安全WFH时,速度的降低是由于生成块过程和验证过程。

Exploring Success Factor for Mobile based Smart Regency Service using TRUTAUT Model Approach 利用TRUTAUT模型方法探索基于移动设备的智能应急服务的成功因素
A. Darmawan, D. Siahaan, T. D. Susanto, Hoiriyah Hoiriyah, B. Umam, Anwari Anwari
Currently, almost every country struggles to apply city management to the concept of intelligent cities. Several previous studies have modelled the success, maturity, and success of information systems to use smart city principles. However, there are significant differences between city and district definition in terms of governance frameworks, regional size, livelihood differences, population, socio-economic, and socio-cultural dimensions. Therefore, work on the Smart District IT assessment requires new and unique studies that can differ substantially from smart cities. This study aims to explore the determinants of the success of Smart Regency services with mobile technology. The model and approach are the TRUTAUT model, which combines the concepts for the TRI and the UTAUT model. Two hundred eighty-nine participants could collect data with a smart cellular district service system - data processing using the SmartPLS v.3.2.8 software. Recent findings indicate that the variables proposed in the TRUTAUT model are a positive and essential relation. This study helps to determine the success of the application of intelligent mobile regional services applications. This study confirms that policymakers pay more considerable attention to critical questions that affect the district's smart cellular services' success.
目前,几乎每个国家都在努力将城市管理应用到智慧城市的概念中。之前的一些研究已经模拟了信息系统的成功、成熟和成功,并使用了智慧城市原则。然而,在治理框架、区域规模、生计差异、人口、社会经济和社会文化维度方面,城市和地区的定义存在显著差异。因此,智能地区的IT评估工作需要新的和独特的研究,这些研究可能与智能城市有很大的不同。本研究旨在探讨移动技术智能摄政服务成功的决定因素。该模型和方法是TRUTAUT模型,它结合了TRI和UTAUT模型的概念。289名参与者可以使用智能蜂窝地区服务系统收集数据-使用SmartPLS v.3.2.8软件进行数据处理。最近的研究结果表明,在TRUTAUT模型中提出的变量是一个积极的和本质的关系。本研究有助于确定智能移动区域服务应用的成功与否。这项研究证实,决策者对影响该地区智能手机服务成功的关键问题给予了更多的关注。

Semantic Classification of Scientific Sentence Pair Using Recurrent Neural Network 基于递归神经网络的科学句对语义分类
Agung Besti, Ridwan Ilyas, Fatan Kasyidi, E. C. Djamal
One development of Natural Language Processing is the semantic classification of sentences and documents. The challenge is finding relationships between words and between documents through a computational model. The development of machine learning makes it possible to try out various possibilities that provide classification capabilities. This paper proposes the semantic classification of sentence pairs using Recurrent Neural Networks (RNN) and Long Short-Term Memory (LSTM). Each couple of sentences is turned into vectors using Word2Vec. Experiments carried out using CBOW and Skip-Gram to get the best combination. The results are obtained that word embedding using CBOW produces better than Skip-Gram, although it is still around 5%. However, CBOW slows slightly at the beginning of iteration but is stable towards convergence. Classification of all six classes, namely Equivalent, Similar, Specific, No Alignment, Related, and Opposite. As a result of the unbalanced data set, the retraining was conducted by eliminating a few classes member from the data set, thus providing an accuracy of 73 % for non-training data. The results showed that the Adam model gave a faster convergence at the start of training compared to the SGD model, and AdaDelta, which was built, gave 75% better accuracy with an F1-Score of 67%.
自然语言处理的一个发展是句子和文档的语义分类。挑战在于通过计算模型找到单词之间和文档之间的关系。机器学习的发展使得尝试提供分类能力的各种可能性成为可能。本文提出了基于循环神经网络(RNN)和长短期记忆(LSTM)的句子对语义分类方法。使用Word2Vec将每一对句子转换成向量。利用CBOW和Skip-Gram进行了实验,得到了最佳组合。结果表明,使用CBOW的词嵌入效果优于Skip-Gram,但仍在5%左右。然而,CBOW在迭代开始时稍微变慢,但趋于收敛时是稳定的。所有六个类别的分类,即等同,相似,特定,不对齐,相关和相反。由于数据集不平衡,通过从数据集中剔除一些类成员来进行再训练,从而为非训练数据提供了73%的准确率。结果表明,与SGD模型相比,Adam模型在训练开始时的收敛速度更快,而建立的AdaDelta模型的准确率提高了75%,F1-Score为67%。

The feature selection techniques are used to find the most important and relevant features in a dataset. Therefore, in this study feature selection technique was used to improve the performance of Anomaly Detection. Many feature selection techniques have been developed and implemented on the NSL-KDD dataset. However, with the rapid growth of traffic on a network where more applications, devices, and protocols participate, the traffic data is complex and heterogeneous contribute to security issues. This makes the NSL-KDD dataset no longer reliable for it. The detection model must also be able to recognize the type of novel attack on complex network datasets. So, a robust analysis technique for a more complex and larger dataset is required, to overcome the increase of security issues in a big data network. This study proposes particle swarm optimization (PSO) Search methods as a feature selection method. As contribute to feature analysis knowledge, In the experiment a combination of particle swarm optimization (PSO) Search methods with other search methods are examined. To overcome the limitation NSL-KDD dataset, in the experiments the CICIDS2017 dataset used. To validate the selected features from the proposed technique J48 classification algorithm used in this study. The detection performance of the combination PSO Search method with J48 examined and compare with other feature selection and previous study. The proposed technique successfully finds the important features of the dataset, which improve detection performance with 99.89% accuracy. Compared with the previous study the proposed technique has better accuracy, TPR, and FPR.
特征选择技术用于在数据集中找到最重要和最相关的特征。因此,本研究采用特征选择技术来提高异常检测的性能。在NSL-KDD数据集上已经开发和实现了许多特征选择技术。但是,随着网络中应用、设备和协议的增多,流量的快速增长,流量数据的复杂性和异构性导致了安全问题。这使得NSL-KDD数据集不再可靠。检测模型还必须能够识别复杂网络数据集上的新型攻击类型。因此,需要一种针对更复杂、更大数据集的强大分析技术,以克服大数据网络中日益增加的安全问题。本研究提出粒子群优化(PSO)搜索方法作为特征选择方法。为了增加特征分析知识,在实验中研究了粒子群优化(PSO)搜索方法与其他搜索方法的结合。为了克服NSL-KDD数据集的局限性,在实验中使用了CICIDS2017数据集。为了验证本研究中使用的J48分类算法所选择的特征。结合J48对PSO搜索方法的检测性能进行了检验,并与其他特征选择和前人的研究进行了比较。该方法成功地发现了数据集的重要特征,提高了检测性能,准确率达到99.89%。与以往的研究相比,该方法具有更高的精度、TPR和FPR。
