The Waste Separation Game to Promote Computational Thinking Through Mixed Reality Technology 通过混合现实技术促进计算思维的废物分类游戏
Worapat Phatarametravorakul, Suphitsara Cheevanantaporn, Pornsuree Jamsri
The primary issue of garbage is its direct impact on the environment and quality of life. Several types of trash have piled up in Thailand. Many individuals don’t use the correct way of waste management because they have lacked knowledge and understanding of how to sort rubbish since childhood. To increase the possibility to fully utilize the knowledge of waste separation correctly, the researcher aims to promote computational thinking through the learning of a game called “Trashman”. This game simulates various objects for situations of sorting garbage into the appropriate sorting bin. Trashman has 3 levels in the game. Each level increases the number of bins and the amount of garbage, starting from level 1-3 which refers to easy, moderate, and difficult levels, respectively. The level indicates the error of separating the waste if putting it into a wrong bin type. The educating about different types of waste separation through the game utilizes Mixed Reality (MR) technology of the Magic Leap One device. The developer’s expectation for an alternative learning medium in the form of a game is to allow players to apply their knowledge by practicing computational skills by sorting garbage correctly. The game evaluates and summarizes scores of each level at the game’s end. This will evaluate player’s performance of CT through their ability separating trash. Moreover, the Sustainable Development Goals can be applied for lifelong learning to follow-up and assessment in furtherance of correct trash sorting.
垃圾的首要问题是它对环境和生活质量的直接影响。泰国堆积了好几种垃圾。许多人没有使用正确的垃圾管理方式,因为他们从小就缺乏如何分类垃圾的知识和理解。为了增加正确充分利用垃圾分类知识的可能性,研究者旨在通过学习一个叫做“垃圾清道夫”的游戏来促进计算思维。这个游戏模拟各种对象的情况下,将垃圾分类到适当的分类箱。《Trashman》在游戏中有3个关卡。每一关都会增加垃圾箱的数量和垃圾的数量,从1-3级开始,分别表示简单、中等和困难的级别。该级别表示如果将废物放入错误的垃圾箱类型中,则分类废物的错误。通过游戏对不同类型的垃圾分类进行教育,利用Magic Leap One设备的混合现实(MR)技术。开发者期望以游戏的形式出现另一种学习媒介,即允许玩家通过正确分类垃圾来练习计算技能,从而应用他们的知识。游戏在游戏结束时评估并总结每个关卡的分数。这将通过玩家分离垃圾的能力来评估他们在CT中的表现。此外,可持续发展目标可用于终身学习的跟踪和评估,以促进正确的垃圾分类。

Flash Defect Detection System of Friction Stir Welding Process Based on Convolutional Neural Networks for AA 6061-T651 基于卷积神经网络的AA 6061-T651搅拌摩擦焊闪光缺陷检测系统
Ulya Ganeswara Alamy, Eka Marliana, A. Wahjudi, I. M. L. Batan, Latifah Nurahmi
An early detection control system for high-speed and objectivity welding defects is needed. Visual Inspection (VT) is an important method and the initial stage before a welded material will be tested at destructive testing. So far, VT has only used human vision, which takes a protracted process and is highly subjective. This paper will contribute to the VT method to control the Friction Stir Welding (FSW) process by detecting the flash defect using image processing and Convolutional Neural Network (CNN). Thus, flash defects in the FSW process can be minimised and detected as early as possible. Image processing and CNN serve as a substitute for human vision. The selection of CNN is considered suitable for detecting an image because the process is fast and detects key features without human supervision, which is carried out by a continuous learning process. 620 images from the FSW process were processed into two groups of datasets. It was processed with two types of CNN architecture, including AlexNet and VGG16. Based on the VT results by CNN, the AlexNet model showed a detection accuracy of 91.03%, while the VGG16 model showed a detection accuracy of 77.35%. From these results, CNN’s success in conducting VT on FSW process control is relatively high and can play a more significant role in checking the results of the FSW process. Therefore, the possibility of flash defects can be minimised and detected as early as possible.
需要一种高速、客观焊接缺陷的早期检测控制系统。目视检测(VT)是一种重要的检测方法,是焊接材料进行破坏性检测前的初始阶段。到目前为止,VT只使用了人类的视觉,这需要一个漫长的过程,而且是高度主观的。本文将利用图像处理和卷积神经网络(CNN)检测闪光缺陷,为VT方法控制搅拌摩擦焊(FSW)过程做出贡献。因此,FSW过程中的闪光缺陷可以最小化并尽早检测到。图像处理和CNN作为人类视觉的替代品。CNN的选择被认为适合于检测图像,因为该过程速度快,并且在没有人工监督的情况下检测关键特征,人工监督是通过一个持续的学习过程来完成的。从FSW过程中得到的620幅图像被处理成两组数据集。使用AlexNet和VGG16两种CNN架构进行处理。基于CNN的VT结果,AlexNet模型的检测准确率为91.03%,而VGG16模型的检测准确率为77.35%。从这些结果来看,CNN在FSW过程控制上进行VT的成功率较高,可以在FSW过程结果的检验中发挥更大的作用。因此,可以最大限度地减少闪光缺陷的可能性,并尽早发现。

Binarized and Full-Precision 3D-CNN in Action Recognition 二值化全精度3D-CNN动作识别
C. W. D. Lumoindong, Rila Mandala
As a part of the video classification task, action recognition is also known as a task with heavy computational load, with models mostly trained on devices with multiple GPUs. The pre-trained models suffer from large size and take a long time to infer the test data, especially on devices with low specifications and mobile devices. The recent development of neural networks introduces the Binarized Neural Network (BNN), which offers a solution to these problems. BNNs are trained with binary activations and weights, which reduces the computation from 32-bits to 1-bit. Theoretically, this feature can perform using 32x less memory and hardware resource compared to the conventional, full-precision neural networks. Theoretically, the conversion from full-precision CNN to BNN should result in a smaller model size and faster inference time. In this research, a binarized 3D CNN model is built using the principles of BNN and tested against the full-precision CNN. The BNN model is able to reach 78.7% train accuracy, 76.3% validation accuracy, and 79.6% inference accuracy, which means that the model is working according to the standards defined in this research.
动作识别作为视频分类任务的一部分,也是一项计算量很大的任务,其模型大多在具有多个gpu的设备上进行训练。预训练模型存在尺寸大、推断测试数据耗时长的问题,特别是在低规格设备和移动设备上。近年来神经网络的发展引入了二值化神经网络(BNN),为这些问题提供了解决方案。bnn使用二进制激活和权重进行训练,从而将计算量从32位减少到1位。理论上,与传统的全精度神经网络相比,该功能可以使用32倍的内存和硬件资源来执行。从理论上讲,从全精度CNN到BNN的转换应该会导致更小的模型尺寸和更快的推理时间。在本研究中,利用BNN原理建立了二值化的三维CNN模型,并针对全精度CNN进行了测试。BNN模型能够达到78.7%的训练精度、76.3%的验证精度和79.6%的推理精度,这意味着该模型按照本研究定义的标准工作。

Thanachote Lertlapnon, Naruebes Lueangrungudom, Sirion Vittayakorn
Algorithm has been heavily used to provide a comfort life for us: from finding the best route in Google map to biometrics authentication on your phone. The significant of algorithm defines Computational thinking (CT) as one of the 21st Century skills. Although CT has been integrated into the education in the past years, many students still struggle with CT concept due to the complication of the topic and limited learning methods provided in school environment. To provide alternative learning approach for algorithmic thinking, we propose a game-base learning system called Protobot. Protobot requires students to apply their CT knowledge, especially the algorithmic thinking to solve problems in the gameplay. The experimental results demonstrate that Protobot fosters the algorithmic thinking skill of the players as well as provides the amusement during the gameplay.
算法已经被大量用于为我们提供舒适的生活:从在谷歌地图上找到最佳路线到在手机上进行生物识别认证。算法的重要性决定了计算思维(CT)是21世纪的技能之一。虽然在过去的几年里,CT已经融入到教育中,但由于主题的复杂性和学校环境提供的学习方法有限,许多学生仍然对CT概念感到困惑。为了为算法思维提供另一种学习方法,我们提出了一个基于游戏的学习系统,称为Protobot。Protobot要求学生运用所学的CT知识,特别是算法思维来解决游戏中的问题。实验结果表明,Protobot不仅培养了玩家的算法思维能力,而且在游戏过程中提供了乐趣。

Electrical Noise Behaviour of High-k Gate-All-Around MOSFET Based on Two-Port Device Network Analysis 基于双端口器件网络分析的高k栅极全能MOSFET电噪声特性
Pankaj Kumar, K. Koley, R. Goswami, A. Maurya, Subindu Kumar
This work investigates the numerical analysis based on multiple noise figures of merit in a high-k gate-all-around MOSFET by considering two-port device analysis. The noise in the device is calculated by analyzing the statistical behavior of random voltage sources at the terminals of the MOSFET represented as a two-port system. Although, HfO2 based GAA MOSFET device shows better ON-state current, yet, the device shows degradation in minimum noise figure, autocorrelation, cross-correlation, optimum source impedance, and noise conductance when compared to SiO2 based devices.

Toward Detection of Small Objects Using Deep Learning Methods: A Review 用深度学习方法检测小物体:综述
Dwi Wahyudi, I. Soesanti, H. A. Nugroho
The field of computer vision, particularly object detection, has undergone significant changes. Most cutting-edge object detectors can accurately detect medium and large objects. Small object detection remains challenging for the majority of object detectors due to low resolution, lack of feature information, small objects appearing in unexpected areas or overlapping with other objects, and small object dataset limitations. Several solutions have been developed to address this issue. This paper provides a brief description and analysis of contemporary general object detectors, such as Faster R-CNN, SSD, and YOLO. In addition, we investigate several techniques to improve object detection performance, particularly for small object detection, from three perspectives: network improvement (multiscale feature, contextual information), input data optimization (super-resolution, image tiling), and dataset enhancement (data augmentation, creating own dataset). Implementing these techniques has been shown to improve the accuracy of contemporary object detectors, particularly for small objects.
计算机视觉领域,特别是物体检测,已经发生了重大的变化。大多数尖端的物体探测器都能准确地探测到大中型物体。由于低分辨率、缺乏特征信息、小目标出现在意外区域或与其他目标重叠以及小目标数据集的限制,小目标检测对大多数目标检测器来说仍然是一个挑战。已经开发了几个解决方案来解决这个问题。本文对Faster R-CNN、SSD和YOLO等现代通用目标检测器进行了简要的描述和分析。此外,我们从三个角度研究了几种提高目标检测性能的技术,特别是对于小目标检测:网络改进(多尺度特征,上下文信息),输入数据优化(超分辨率,图像平铺)和数据集增强(数据增强,创建自己的数据集)。实施这些技术已被证明可以提高当代物体探测器的准确性,特别是对于小物体。

Automatic Lymph Node Classification with Convolutional Neural Network 基于卷积神经网络的淋巴结自动分类
Ason Uthatham, Nutcha Yodrabum, Chanya Sinmaroeng, Taravichet Titijaroonroj
Manual lymph node classification is a tedious and time-consuming task. It requires a histopathologist to discriminate a lymph node from other look-alike kinds of tissues. The lymph node is easily misunderstood with other tissues because its shape and color might be similar to the others tissue around it. To automate this task, we present an automatic lymph node classification with convolutional neural network (CNN). In addition, we compared eight existing CNNs to ensure that we discover the best architecture for discriminating lymph node. DenseNet architecture provided the highest performance among AlexNet, VGG, GoogLeNet, ResNet, SqueezeNet, MobileNet, and EfficientNet, the highest accuracy at 0.994 and an F1score of 0.996. DenseNet accomplished the highest performance from two advantages: (i) fewer parameters and (ii) Dense connectivity.

Power Wheeling Hybrid System of PV-Pumped Storage Using MW-KM Method 基于MW-KM方法的pv -抽水蓄能动力轮式混合系统
Frida Hasana, S. P. Hadi, M. I. B. Setyonegoro, Tumiran
It is widely recognized that using conventional power plants requires an expensive and massive fossil fuel supply. This can be minimized by doing a hybrid conventional power plants and renewable energy sources (RES), along with pumped storage. In this paper, the optimal scheduling of that hybrid system is simulated using MATPOWER Optimal Scheduling Tool (MOST) to obtained the most optimal and economic condition. Utilize the scheduling outcomes and the assumption that power wheeling is implemented, this paper calculates the network lease. This paper provides the leasing calculation using MW-km method with the reverse, absolute, and dominant approach by considering the direction of power flow. According to the simulation results, a scheduling method that includes pumped storage and RES can reduce conventional plant operations. Moreover, this paper shows that the reverse approach produced the lowest calculation results compared to the other approaches.
人们普遍认为,使用传统发电厂需要大量昂贵的化石燃料供应。这可以通过将传统发电厂和可再生能源(RES)以及抽水蓄能相结合来最小化。本文利用MATPOWER最优调度工具(MOST)对该混合系统的最优调度进行了仿真,得到了最优和最经济的状态。利用调度结果,在实现动力轮转的假设下,计算网络租期。本文在考虑潮流方向的情况下,采用反向、绝对、优势的兆瓦公里法进行租赁计算。仿真结果表明,一种包含抽水蓄能和可再生能源的调度方法可以减少电厂的常规操作。此外,本文还表明,与其他方法相比,反向方法的计算结果最低。
