Construction of fault diagnosis system for control rod drive mechanism based on knowledge graph and Bayesian inference

Knowledge graph technology has distinct advantages in terms of fault diagnosis.In this study,the control rod drive mechanism(CRDM)of the liquid fuel thorium molten salt reactor(TMSR-LF1)was taken as the research object,and a fault diagnosis system was proposed based on knowledge graph.The subject–relation–object triples are defined based on CRDM unstructured data,including design specification,operation and maintenance manual,alarm list,and other forms of expert experience.In this study,we constructed a fault event ontology model to label the entity and relationship involved in the corpus of CRDM fault events.A three-layer robustly optimized bidirectional encoder representation from transformers(RBT3)pre-training approach combined with a text convolutional neural network(TextCNN)was introduced to facilitate the application of the constructed CRDM fault diagnosis graph database for fault query.The RBT3-TextCNN model along with the Jieba tool is proposed for extracting entities and recognizing the fault query intent simultaneously.Experiments on the dataset collected from TMSR-LF1 CRDM fault diagnosis unstructured data demonstrate that this model has the potential to improve the effect of intent recognition and entity extraction.Additionally,a fault alarm monitoring module was developed based on WebSocket protocol to deliver detailed information about the appeared fault to the operator automatically.Furthermore,the Bayesian inference method combined with the variable elimination algorithm was proposed to enable the development of a relatively intelligent and reliable fault diagnosis system.Finally,a CRDM fault diagnosis Web interface integrated with graph data visualization was constructed,making the CRDM fault diagnosis process intuitive and effective.

Statistical Models for Web Pages Usability

The usability of an interface is a fundamental issue to elucidate. Many researchers argued that many usability results and recommendations lack empirical and experimental data. In this research, the usability of the web pages is evaluated using several carefully selected statistical models. Universities web pages are chosen as subjects for this work for ease of comparison and ease of collecting data. A series of experiments has been conducted to investigate into the usability and design of the universities web pages. Prototype web pages have been developed according to the structured methodologies of web pages design and usability. Universities web pages were evaluated together with the prototype web pages using a questionnaire which was designed according to the Human Computer Interactions (HCI) heuristics. Nine (users) respondents’ variables and 14 web pages variables (items) were studied. Stringent statistical analysis was adopted to extract the required information to form the data acquired, and augmented interpretation of the statistical results was followed. The results showed that the analysis of variance (ANOVA) procedure showed there were significant differences among the universities web pages regarding most of the 23 items studied. Duncan Multiple Range Test (DMRT) showed that the prototype usability performed significantly better regarding most of the items. The correlation analysis showed significant positive and negative correlations between many items. The regression analysis revealed that the most significant factors (items) that contributed to the best model of the universities web pages design and usability were: multimedia in the web pages, the web pages icons (alone) organisation and design, and graphics attractiveness. The results showed some of the limitations of some heuristics used in conventional interface systems design and proposed some additional heuristics in web pages design and usability.

The Reproduction of Chinese Painting in the Digital Age

This paper investigates the reproduction of Chinese painting in the digital age. In particular, how does a website asan interface influence viewers’ response to a Chinese handscroll? The paper begins with a critical description of aweb interface of Freer Gallery of Art and Arthur M. Sackler Gallery, followed by an analysis of the originalpainting. Fishermen on an Autumn River, that the interface digitizes and displays. The last section points out theinfluence of digitization on the relationship between viewers and digital heritage.

Design and Development of a New Control System for Improving Energy Efficiency and Demand Response

One of the best strategies for improving energy efficiency in any system is using the energy resources in the facilities properly.Using energy systems only when they are absolutely necessary is one of the best cost-benefit ratio strategies,i.e.the best energy saving strategy is,not using it.The aim of this paper resides on introducing a new Energy Management and Control System(EMCS),developed by the authors,which has been installed at the Universitat Politècnica de València.Alongside the paper,the architecture,the components and the installation cost analysis of the EMCS,as well as management actions implemented in the university and the obtained results are presented.Furthermore,this innovative system has been designed to improve demand response in energy systems by providing consumers with a tool for responding actively to energy demands,and also to provide all the different electrical market agents with a communication and business platform for exchanging information.

Emoji Essence:Detecting User Emotional Response on Visual Centre Field with Emoticons

User experience is understood in so many ways,like a one on one interaction(subjective views),online surveys and questionnaires.This is simply so get the user’s implicit response,this paper demonstrates the underlying user emotion on a particular interface such as the webpage visual content based on the context of familiarisation to convey users’emotion on the interface using emoji,we integrated physiological readings and eye movement behaviour to convey user emotion on the visual centre field of a web interface.The physiological reading is synchronised with the eye tracker to obtain correlating user interaction,and emoticons are used as a form of emotion conveyance on the interface.The eye movement prediction is obtained through a control system’s loop and is represented by different color display of gaze points(GT)that detects a particular user’s emotion on the webpage interface.These are interpreted by the emoticons.Result shows synchronised readings which correlates to area of interests(AOI)of the webpage and user emotion.These are prototypical instances of authentic user response execution for a computer interface and to easily identify user response without user subjective response for better and easy design decisions.

Decision support system for the mobile volcano fast response system

A mobile volcano fast response system(VFRS)that can be used for volcano monitoring in case of volcanic unrest anywhere in the world is currently under development in Germany.The main goal of the project called Exupéry is to provide the communication technology for stations in the field and an expert system that collects all data from various sources,assembles them in a database,and allows users to assess the data through one common web GIS interface.The system also includes an integrated automatic alert level including the alert level estimation in order to characterize the activity state of the volcano.The web GIS interface serves as a decision support system to assist scientists and local authorities in deciding how to react in the case of volcanic unrest.
