Multi-Scale Electrical Appliance Load Signature for Non-Intrusive Load Monitoring Classification 非侵入式负荷监测分类的多尺度电器负荷特征
Manith Chou, Kosorl Thourn, Rothvichea Chea
Non-intrusive Load Monitoring is a system that is able to monitor energy consumption and provide a detailed energy breakdown to the end consumer. This paper deals with one cycle of steady-state voltage and current used to construct a voltage-current (V-I) trajectory. After retrieving one cycle signals of voltage and current, the Fourier phase correction technique is applied on them to avoid low accuracy or mismatch in classification d ue to the starting point selection of one period signal. Then, Triangle Area Representation (TAR) at different side lengths is introduced to describe the V-I trajectory of each electrical load appliance. Due to the very high dimensional subspace of TAR signature, it is then beneficial to use principal component analysis for creating a low-dimensional space feature. Finally, the weighted k-Nearest neighbor is employed to classify each type of appliance according to the k-Nearest number. Plug-Load Appliance Identification Dataset is applied in the assessment of the proposed algorithm which shows good performance with high accuracy of 97.43%.
非侵入式负载监测是一种能够监测能源消耗并向最终用户提供详细能源分解的系统。本文讨论了一个周期的稳态电压和电流,用来构造电压-电流(V-I)轨迹。在获取电压和电流的一个周期信号后,对其进行傅里叶相位校正,避免了由于选取一个周期信号的起始点而导致分类精度低或失配。然后,引入不同边长的三角面积表示(TAR)来描述每个电气负载设备的V-I轨迹。由于TAR签名的子空间非常高维,因此使用主成分分析来创建低维空间特征是有益的。最后,利用加权k近邻,根据k近邻数对各类器具进行分类。应用插件负载设备识别数据集对该算法进行了评估,结果表明该算法具有良好的性能,准确率高达97.43%。

A Novel Framework for Co-designing of An Artificial Intelligence Based Television-enabled Application to Address Social Isolation and Alleviating Loneliness for Older People 共同设计基于人工智能的电视应用程序的新框架,以解决老年人的社会隔离和减轻孤独感
M. Hasan, Pamela Knight, Marzia Hoque Tania, Abu Kowshir Bitto, Aka Das, Hitesh Punja
Ageing is a natural and unavoidable process that all humans go through, and it is marked by a series of typical physical, psychological, and social changes. Increasing social isolation and loneliness are severe yet underappreciated public health risks, affecting people of all ages and backgrounds. Therefore, we propose to co-design a novel Television Enable Application (TEA) for healthy ageing in this study. Our co- designed AI-based television-enabled application (TEA) can adapt to home television, which is universally helpful in enabling older people and others to connect with befriending services. In this paper, we have completed an extensive literature review and propose a framework for co-designing the application with older people. We adopt an agile approach to developing TEA with iterations, inception, and elaboration, of the prototype. Additionally, a co-creation methodology and a quantitative evaluation of social isolation and loneliness will be used to improve the prototype between the inception and elaboration phases and assess the impact of TEA on social isolation and loneliness. To evaluate the effectiveness of befriending and of TEA versus traditional befriending, we propose a series of mixed two (group: traditional versus TEA) x 2(time: baseline and follow-up) ANOVAs tests will be considered for each questionnaire measure to assess if there are any statistically significant changes in scores over time, and between groups with alpha level 0.05. The developed TEA will be capable of addressing loneliness and isolation by connecting ageing people. TEA will also provide older people with a feature to communicate with care services.
衰老是所有人类都要经历的一个自然的、不可避免的过程,它以一系列典型的生理、心理和社会变化为标志。日益加剧的社会孤立和孤独是严重的公共卫生风险,但未得到充分重视,影响到所有年龄和背景的人。因此,我们建议在本研究中共同设计一种新的电视使能应用程序(TEA)。我们共同设计的基于人工智能的电视启用应用程序(TEA)可以适应家庭电视,这对于使老年人和其他人与友好服务联系非常有帮助。在本文中,我们完成了广泛的文献综述,并提出了一个与老年人共同设计应用程序的框架。我们采用敏捷的方法来开发TEA,包括原型的迭代、初始化和精化。此外,将采用共同创造方法和对社会孤立和孤独进行定量评估,以改进在初始阶段和详细阶段之间的原型,并评估TEA对社会孤立和孤独的影响。为了评估友谊以及TEA与传统友谊的有效性,我们提出了一系列混合两(组:传统与TEA) x 2(时间:基线和随访)方差分析,将考虑每个问卷测量值,以评估分数随时间的变化是否有统计学意义,以及组间α水平为0.05。发达的TEA将能够通过连接老年人来解决孤独和孤立问题。TEA还将为老年人提供与护理服务沟通的功能。

Deep Facial Features for Analysing Artistic Depictions - A Case Study in Evaluating 16th and 17th Century Old Master Portraits 分析艺术描绘的深层面部特征——评估16和17世纪早期大师肖像的案例研究
H. Ugail, Howell Edwards, Timothy J. Benoy, Christopher Brooke
Convolutional neural network (CNN) based deep learning has recently become the standard de facto for computer assisted image analysis and classification. In this work, we use an in-house trained deep face recognition model to extract facial features from images of old portraits to compare their degree of similarity. Taking the well-known Visual Geometry Group (VGG) deep learning model as the basis, our in-house trained model is fine-tuned for enhanced facial similarity analysis, providing particular attention to the effects from prominent parts of the face, such as the eyes, nose and mouth features. We show how this model can be efficiently utilised to evaluate faces present in age-old master portraits. More specifically, we undertake facial similarity analysis of the faces in the oil paintings of Madonna and Child of de Brécy Tondo and Sistine Madonna by Raphael, of which the former has been the subject of national and international research for nearly 40 years.
基于卷积神经网络(CNN)的深度学习最近已经成为计算机辅助图像分析和分类的标准。在这项工作中,我们使用内部训练的深度人脸识别模型从旧肖像图像中提取面部特征,以比较它们的相似程度。我们的内部训练模型以著名的视觉几何组(VGG)深度学习模型为基础,对增强的面部相似性分析进行了微调,特别关注面部突出部位(如眼睛、鼻子和嘴巴)的效果。我们展示了如何有效地利用这个模型来评估古代大师肖像中的面孔。更具体地说,我们对拉斐尔油画《麦当娜》和《德·布拉马西·通多的孩子》和《西斯廷圣母》中的面部进行了面部相似性分析,其中前者是近40年来国内外研究的主题。

An Explainable Real-time Decision Support System for Identifying Fish Diseases and Analysing Water Quality 一种可解释的鱼病识别及水质分析实时决策支持系统
Nazia Hameed, M. Hassan, M. A. Hossain
Fishes account for approximately 15% of the animal protein intake of the human population globally and is the main source of income for some developing countries like Cambodia. Fish is a traditional staple in the Cambodian diet and vital to nutrition and food security. Due to a lack of human resources with expertise in research into detecting fish diseases, breeding, and raising technologies, most farmers are struggling to increase the productivity of fish. In this research work, an intelligent classification framework is proposed for increasing the productivity of fish farmers by providing them with a facility to detect fish diseases along with analyzing the water quality. To understand the problems faced by the local farmers, the research team visited the six fisheries farms in the Takeo Province and collected the requirements. After the identification of the key challenges, a general framework is proposed for the early detection of fish diseases. The proposed framework will help the local farmers to educate them about the fish diseases and help them to improve the fish productivity.
鱼类约占全球人口动物蛋白摄入量的15%,是柬埔寨等一些发展中国家的主要收入来源。鱼是柬埔寨饮食中的传统主食,对营养和粮食安全至关重要。由于缺乏在检测鱼类疾病、育种和饲养技术方面具有专门知识的人力资源,大多数农民都在努力提高鱼类的生产力。在这项研究工作中,提出了一种智能分类框架,通过为养鱼户提供检测鱼类疾病和分析水质的设施来提高他们的生产力。为了了解当地农民面临的问题,研究小组访问了武武省的六个渔场并收集了需求。在确定了主要挑战之后,提出了早期发现鱼类疾病的一般框架。拟议的框架将帮助当地农民对鱼类疾病进行教育,并帮助他们提高鱼类产量。

Evaluating Organization's Portfolio of Long-horizon Strategic Action Plans: An Integrated Delphi-DEMATEL-ANP Approach 评估组织的长期战略行动计划组合:综合Delphi-DEMATEL-ANP方法
Fidero Kuok, Angkeara Bong, M. Promentilla
Strategic foresight allows the organization to adapt and cope with the challenges of the next decade and beyond by revealing internal mental models, encouraging reflection and understanding complexity further on the boundaries of organizational knowledge. This paper thus demonstrates a novel method to facilitate collaborative planning using long-range foresight for an organization. Using the Delphi technique, the proposed method involves the identification of key products, periods of products realization, products dependency and ranking, and the formation of a portfolio of long-horizon strategic action plans that are perceived as achievable within the time horizon of 2030. The prioritization of these actions is then investigated using an integrated Decision Making Trial and Evaluation Laboratory (DEMATEL)-Analytic Network Process (ANP) approach.

Spatiotemporal Gait Analysis for Cardiovascular Disease 心血管疾病的时空步态分析
Subhadra Joshi, Santosh Khanal, Rabindra Bista
Gait analysis is a way of analyzing the subjects' walking pattern which has been discovered as an indicator for the identification of symptoms of the disease after among all the other clinical parameters. Gait disorder having no apparent reason is associated with cardiovascular disease and gait imbalance is the major factor for fall and fall related accidents. This study puts an effort to perform quantitative measurements of spatiotemporal gait parameters for the patients of cardiovascular disease using wearable sensor and explores the clinical symptoms from gait pattern. The research is carried out on 16 Healthy controls and 53 Cardiovascular patients. The result of the analysis presented that the gait parameters of the patients are greatly varied than that of Healthy Controls (HCs) which may serve as early indication of the symptoms of cardiovascular disease. This is a new idea in analyzing walking pattern of population suffering from different disease with different age-group and sex based on the various case studies in the same domain.
步态分析是在众多临床参数之后,对被试的行走方式进行分析的一种方法,它被发现是识别疾病症状的一个指标。无明显原因的步态障碍与心血管疾病有关,步态不平衡是导致跌倒和跌倒相关事故的主要因素。本研究试图利用可穿戴传感器对心血管疾病患者的时空步态参数进行定量测量,并从步态模式中探索临床症状。该研究在16名健康对照者和53名心血管患者中进行。分析结果表明,患者的步态参数与健康对照(hc)的步态参数差异很大,这可能是心血管疾病症状的早期指示。这是在同一领域的不同病例研究的基础上,分析不同年龄、性别的不同疾病人群步行模式的新思路。

Vibro-vestibular Wheelchair for Vehicle Riding Experience in Immersive Virtual Reality 沉浸式虚拟现实中车辆乘坐体验的振动前庭轮椅
Vibol Yem, Tsubasa Morita, Y. Ikei
In this study, we modified a wheelchair by attaching two direct current motors to drive each wheel and provide whole-body vibration and vestibular sensation. This motion simulator can be used to enhance the vehicle riding experience in immersive virtual reality or telepresence. We examined herein the effectiveness of the translational motion feedback from the vestibular wheelchair when presenting recorded images with spatial motion from the stereoscopic cameras on the head-mounted display (HMD). The results of the intensity comparison with the magnitude estimation method showed that the perception of vestibular acceleration by the wheelchair was stronger than that of visually presented acceleration in the HMD. Moreover, approximately 25% intensity of the visual acceleration is appropriate for suppressing virtual reality sickness. The questionnaire results revealed that adding vestibular acceleration to the visual acceleration increases the sense of presence, regardless of the vestibular sensation intensity.
在这项研究中,我们改装了轮椅,通过安装两个直流电机来驱动每个轮子,并提供全身振动和前庭感觉。该运动模拟器可用于增强沉浸式虚拟现实或远程呈现中的车辆乘坐体验。在此,我们研究了前庭轮椅在呈现头戴式显示器(HMD)上的立体摄像机记录的空间运动图像时平移运动反馈的有效性。结果表明,轮椅对前庭加速度的感知强于HMD视觉呈现的加速度。此外,大约25%的视觉加速度强度对于抑制虚拟现实病是合适的。问卷调查结果显示,无论前庭感觉强度如何,在视觉加速的基础上增加前庭加速都会增加存在感。

This paper presents an investigation into the challenges of cybersecurity readiness in developing countries, particularly for the different age groups of populations in Cambodia. This includes a case study through a survey to demonstrate the potential risk in Cambodia as one of the developing countries. We designed the survey questionnaire considering the theme of - what are the key issues that demonstrate users are the weakest link to cybercriminals. The questionnaire covers personal digital readiness issues related to passwords, phishing, malware, backups, security control of PCs, etc. A wide range of participants from three different age groups demonstrated their understanding of cybersecurity awareness through this survey. The data collected through this survey were analyzed and presented to demonstrate the potential risks of using digital technology in the community in developing countries. It is noted that among various challenges, many users have weaknesses in considering strong and multiple passwords, which is the most important cybersecurity concern for authentication. Finally, the research outcomes provided a recommendation for developing countries, including the demand for personalized learning platforms.
本文介绍了对发展中国家网络安全准备的挑战的调查,特别是对柬埔寨不同年龄组的人口。这包括通过一项调查进行个案研究,以证明柬埔寨作为发展中国家之一的潜在风险。我们设计的调查问卷考虑的主题-什么是关键问题,证明用户是网络罪犯的最薄弱环节。调查问卷涵盖了与密码、网络钓鱼、恶意软件、备份、个人电脑安全控制等相关的个人数字准备问题。通过这次调查,来自三个不同年龄组的广泛参与者展示了他们对网络安全意识的理解。通过这项调查收集的数据进行了分析和展示,以证明在发展中国家的社区中使用数字技术的潜在风险。值得注意的是,在各种挑战中,许多用户在考虑强密码和多个密码方面存在弱点,这是身份验证中最重要的网络安全问题。最后,研究成果为发展中国家提供了建议,包括个性化学习平台的需求。
