Supermarkets are modern markets that sell various household needs ranging from equipment items to various food products, one of which is beef. Consuming beef can have good or bad effects depending on the quality of the freshness of the beef itself. Therefore, before the beef is sold and consumed by the customer, it is necessary first to control the quality of the freshness of the beef. In supermarkets, the process of controlling the quality of beef still uses manual methods, so that the output produced is inaccurate and requires a long time. The presence of IoT technology can overcome these problems, so the process of controlling the quality of beef can be faster and more accurate. In this study, the controlling system is proposed to identify the quality of freshness of beef, the quantity of beef and temperature control in the sales rack. This controlling system utilizes NodeMCU microcontroller, three gas sensors (MQ-136, MQ-137, and TGS-2602), TCS-3200 color sensors, LED lights, buzzers, HC-SR04 ultrasonic sensors and LM35 temperature sensors. The workings of this system are to detect the gas and color produced from the beef and detect the temperature and presence of beef on each side of the rack. It can be concluded that the success of the proposed system has fairly good representation, in accordance with the theory regarding the level of freshness of beef that already exists.
超市是现代市场,出售各种家庭需求,从设备到各种食品,其中之一是牛肉。食用牛肉的好坏取决于牛肉本身的新鲜度。因此,在牛肉出售和消费者消费之前,首先要控制牛肉的新鲜度质量。在超市中,牛肉的质量控制过程仍然采用人工的方法,这样生产出来的产量不准确,需要很长时间。物联网技术的存在可以克服这些问题,因此控制牛肉质量的过程可以更快、更准确。在本研究中,提出了一种控制系统来识别牛肉的新鲜度、牛肉的数量和销售货架上的温度控制。该控制系统采用NodeMCU微控制器,三个气体传感器(MQ-136, MQ-137和TGS-2602), TCS-3200颜色传感器,LED灯,蜂鸣器,HC-SR04超声波传感器和LM35温度传感器。该系统的工作原理是检测牛肉产生的气体和颜色,并检测机架两侧牛肉的温度和存在。可以得出结论,根据已经存在的关于牛肉新鲜度水平的理论,所提出的系统的成功具有相当好的代表性。

The clustering task aims to assign a cluster for each observation data in such a way that observations data within each cluster are more homogeneous to one another than with those in the other groups. Its wide applications in many research fields have motivated many researchers to propose a plethora of clustering algorithms. K-medoids are a prominent clustering algorithm as an improvement of the predecessor, K-Means algorithm. Despite its widely used and less sensitive to noises and outliers, the performance of K-medoids clustering algorithm is affected by the distance function. This paper presents experimentation findings to compare the performance of K-medoids clustering algorithm using Euclidean, Manhattan and Chebyshev distance functions. In this study the K-medoids algorithm was tested using the village status dataset from Gorontalo Province, Indonesia. Execution time and Davies Bouldin Index were used as performance metrics of the clustering algorithm. Experiment results showed that methods of Manhattan distance and Euclidean distance with the Index Davies value of 0.050.
聚类任务的目的是为每个观测数据分配一个聚类,这样每个聚类中的观测数据彼此之间比其他组中的观测数据更均匀。它在许多研究领域的广泛应用促使许多研究人员提出了大量的聚类算法。K-medoids是一种突出的聚类算法,是对其前身K-Means算法的改进。尽管k - medioids聚类算法应用广泛,对噪声和离群值的敏感性较低,但其性能受到距离函数的影响。本文给出了实验结果,比较了欧氏距离函数、曼哈顿距离函数和切比雪夫距离函数下k -媒质聚类算法的性能。在本研究中,使用来自印度尼西亚Gorontalo省的村庄状态数据集对k - mediids算法进行了测试。采用执行时间和Davies Bouldin指数作为聚类算法的性能指标。实验结果表明,曼哈顿距离和欧几里得距离方法的指数戴维斯值为0.050。

In this study, the characterization of the magnetic induction coil sensor for detecting void within the steel plate has been conducted. The study aims to evaluate the performance of coil designs in measuring some objects accurately. Experiments were performed by varying the frequency from 10 kHz to 2.5 MHz with an input voltage of 20 V. The results obtained show that all designs can distinguish air and normal steel objects by amplitude measurements. Only designs 3 and 4, however, can distinguish the normal and defect steels. Design 3 can differentiate them at the frequency of 250 kHz, while design 4 can distinguish at the frequency of 50 kHz. From different phase measurements, no significant differences are presented by all designs.

Solar power plant(SPP) installation which is located in remote areas, provides some benefits for the community, not only an economic aspect but also social, and cultural improvements. Moreover, the SPP is used to exist an electrical load, which is combined with conventional power plants through some networks, or it is operated standalone in remote areas. This operation requires great efforts for controlling and monitoring because of a faraway location. In these studies, a remote monitoring system (RMS) is proposed and developed for monitoring performances of the photovoltaic power plant without visiting the location. The RMS sends data using a radio frequency and displays in voltage, current and power values. Test results show that a portable designing of RMS can be used to measure the SPP and it provides convenient monitoring for the operating condition and technical performance. This portable device is composed of a microcontroller, monitoring display, data sender and receiver, and battery. In addition, several tests show that the sunlight intensity measurement has an error compared with the measuring reference. Data testing is performed at fixed distances between the amount meters and time response also depends on the transmitting distance.
太阳能发电厂(SPP)安装在偏远地区,为社区提供了一些好处,不仅在经济方面,而且在社会和文化方面都有所改善。此外,SPP用于存在电力负荷,通过某些网络与传统发电厂相结合,或在偏远地区单独运行。由于地点较远,该行动需要很大的控制和监测力度。在这些研究中,提出并开发了一种远程监测系统(RMS),用于在不访问现场的情况下监测光伏电站的性能。RMS使用射频发送数据,并显示电压、电流和功率值。试验结果表明,便携式RMS可用于SPP的测量,为监测SPP的运行状况和技术性能提供了方便。该便携式设备由微控制器、监控显示器、数据发送器和接收器以及电池组成。此外,多次试验表明,与测量基准相比,测量结果存在误差。数据测试是在量计之间的固定距离上进行的,时间响应也取决于传输距离。

The availability of electricity demand is very high. Many households and industrial equipment are using electricity as the source energy. The reliability of the power system in saving the budget is very much needed. This can be succeeded by doing good and proper operation planning. The important step of the electric power system operation planning is to predict load electricity. The load forecasting can support the corporations of electricity to assign the cost and power generation. Long-term forecasting is a technique of predicting periods for more than one year. The old data will be a guide to solve the issues. In this research, the concept of generalized regression neural network (GRNN) is to predict long-term electricity load. The advantage of the GRNN method can estimate the absolute function between input and output data sets directly from training data. The research was compared to the results of the actual data, Feed Forward Backpropagation Neural Network (FFBNN), Cascade Forward Backpropagation Neural Network (CFBNN) and Generalized Regression Neural Network (GRNN). The results of the study will be measured and validated using the Mean Absolute Deviation (MAD) and Mean Absolute Percentage Error (MAPE) methods.

Feature selection is the pre-processing step that is widely used, especially in the field of data mining, to simplify processes that can reduce costs and computing time. Selected features can improve the best classification accuracy. In this work, a wrapper method approach is proposed using a modified harmony search. Modification is to update memory harmony using binary encoding. The coding process is adopted from the coding process of genetic algorithms for feature selection. The process of finding a new solution is done by manipulating each variable of the decision solution based on the harmony memory consideration and pitch adjustment procedures and the non-uniform mutation procedure. Evaluate its features using a support vector machine and is called a modified HS-SVM. The results showed that the proposed method has the same genetic algorithm performance for feature selection with SVM classification (GA-SVM), but has faster access time. This performance will reduce costs and computing time, especially if applied to high dimensional data. Both of these algorithms have 96.6 percent accuracy with one feature selected, and the harmony memory size is 50, and the generation size is 100.
特征选择是广泛使用的预处理步骤,特别是在数据挖掘领域,它可以简化处理过程,从而降低成本和计算时间。所选择的特征可以提高最佳的分类精度。在这项工作中,提出了一种使用改进和声搜索的包装方法。修改是使用二进制编码更新内存和谐。编码过程采用遗传算法的编码过程进行特征选择。基于和声记忆考虑和音调调整过程以及非均匀突变过程,通过对决策解的每个变量进行操作来寻找新解的过程。使用支持向量机评估其特征,称为改进的HS-SVM。结果表明,该方法在特征选择方面具有与支持向量机分类(GA-SVM)相同的遗传算法性能,但具有更快的访问时间。这种性能将降低成本和计算时间,特别是如果应用于高维数据。这两种算法在选择一个特征时准确率都达到96.6%,和谐内存大小为50,生成大小为100。

This paper considers multi-robot search problems where a group of robots must discover and allocate themselves to targets. To solve this problem, we embed the robot with an algorithm called the Neighborhood with the Guaranteed Convergence Particle Swarm Optimization (N-GCPSO). This study considers the problem in a simulation environment. To reduce collision between robots, we integrate the N-GCPSO algorithm with a spatial particle extension algorithm. Simulation results show that the integration of N-GCPSO with a spatial partial extension algorithm increases the effectiveness of N-GCPSO by reducing the number of collisions between robots without reducing its performance in discovering and allocating targets.

Simulation results show that the integration of N-GCPSO with a spatial partial extension algorithm increases the effectiveness of N-GCPSO by reducing the number of collisions between robots without reducing its performance in discovering and allocating targets.","PeriodicalId":375166,"journal":{"name":"2020 International Conference on Smart Technology and Applications (ICoSTA)","volume":"594 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126904252","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}

YouTube is the biggest video-sharing website on the internet. Two billion users accessing YouTube every month and watch for one billion hours of video every day. Around 70% of YouTube watch time comes from mobile devices. Therefore, improving the quality of customer experience at a satisfactory level is a must for a network provider. Otherwise, customers will be dissatisfied and possibly switching to another network provider. A customer-centric strategy must be done to target the most profitable ones. Thus, understanding how quality of service (QoS) parameters can affect the Quality of Experience (QoE) is a significant consequence. This study aimed to segment the experiences of customers in accessing streaming videos on YouTube. Throughput, delay, and latency were used as the parameters of Quality of Service (QoS). The result shows that there are three segmentation formed, namely high, middle, and low. Those segments show the level of customers’ experiences based on QoS parameters used.
YouTube是互联网上最大的视频分享网站。每月有20亿用户访问YouTube,每天观看10亿小时的视频。大约70%的YouTube观看时间来自移动设备。因此,将客户体验的质量提高到令人满意的水平是网络提供商必须要做的。否则,客户将不满意,并可能转向另一个网络提供商。以客户为中心的战略必须针对最有利可图的客户。因此,理解服务质量(QoS)参数如何影响体验质量(QoE)是一个重要的结果。这项研究旨在细分客户在YouTube上访问流媒体视频的体验。吞吐量、延迟和延迟被用作服务质量(QoS)的参数。结果表明,形成了高、中、低三个分段。这些细分显示了基于所使用的QoS参数的客户体验水平。
