13th International conference on Ambient Systems, Networks and Technologies, ANT 2022 / 5th International conference on Emerging data and Industry 4.0, EDI40 2022

作者： Zhang, Ling Liu, Xiao Chen, Qian Zhou, Yun Xu, Tao Faculty of Education Shaanxi Normal University 199 South Chang'an Road Xi'an710062 China School of Software Northwestern Polytechnical University 127 West Youyi Road Xi'an710072 China

Eye tracking technology can reflect human attention and cognition, widely used as a research tool. To analyze eye movement data, users need to determine a specific area known as areas of interests (AOIs). Although existing tools offer dynamic AOIs functions to process visual behavior on moving stimuli, they may ask users to use markers to specify contours of moving stimuli in the physical environment or define AOIs manually on screen. This paper proposes a toolbox named Eyebox to 1) recognize dynamic AOIs automatically based on SIFT and extract eye movement indicators, as well as 2) draw fixations. We also design a user-friendly interface for this toolbox. Eyebox currently supports processing data recorded from the Pupil Core device. We compared results processed by manual with by Eyebox in a custom eye-tracking dataset to evaluate this toolbox. The accuracy of 3/4 data for AOI1 is above 90%, and the accuracy of 4/5 data for AOI2 is higher than 90%. Finally, we conducted a user study to test the usability and user experience of EyeBox. © 2022 Elsevier B.v.. All rights reserved.

This research paper addresses the topics of the environment perception domain to realise the solution for connected autonomous mobility by using simulation softwares and real life sensors in tandem. The camera and lidar sensor simulation is performed for a specific scenario arising in the environment and the simulation results, sensor readings and the binary occupancy grids received from sensor simulations are analysed. The RealSense Depth Camera is used to perform visual mapping of the static environment for static obstacle perception and map generation whereas the SICK 2D lidar is used to create a dynamic probabilistic occupancy grid for perceiving the dynamic obstacles in the environment. The results from the sensors in simulation and real life are compared, analysed and validated. The dynamic probabilistic occupancy is used as a foundation to further develop an occupancy prediction model which predicts the future occupancy of any dynamic obstacle based on its velocity and direction of motion. Furthermore, a framework is conceptualised for the vehicle to Everything (v2X) communication system which includes the identification and determination of the essential communication infrastructure, type of data, recipients, rate of data transfer and ROS communication nodes.

Managed Pressure Drilling (MPD) is a crucial technique in the oil and gas industry, ensuring optimal pressure conditions to reduce risks like bore instability and blowouts. Accurate Bottom Hole Pressure (BHP) forecasting is essential for real-time decision-making, but traditional methods often fail to capture the complex dynamics of drilling environments. This paper introduces a Bidirectional Long Short-Term Memory Recurrent Neural Network (BiLSTM-RNN) model for BHP forecasting in MPD. The process includes data exploration, cleaning, pattern identification, feature engineering, and dimensionality reduction to enhance computational efficiency. The BiLSTM-RNN model addresses the vanishing gradient problem and passes in time-series analysis. Simulations in Python achieved reliable error metrics, including MSE of 31942.15, MAE of 136.71, MAPE of 13.02, RMSE of 178.72, and an R2-score of 0.6, demonstrating its effectiveness in improving drilling performance and safety.

Non-seismic methods NSMin geophysics are a crucial addition to classical seismic information. It helps to make decisions at early stages of geological exploration in case of limited information value conditions and provide a new knowledge about geological structure. While seismic exploration remains as the most spreading technique in field geophysics, non-seismic methods predominantly play a role of auxiliary methods, more often particular cases advocate self-sufficiency of NSM in application to exploration geophysical problems. The restoration of structural boundaries is especially important to restore structural boundaries in the space between seismic survey profiles. A simple solution in the form of interpolation does not provide the necessary prediction accuracy, and requires the creation of a complex, often nonlinear model, which is possible using machine learning MLmethods. There is a large number of features at one measurement point - the values of the geophysical fields and their transformations derivatives, filters in a window of different widths. The analysis of the importunateness of each feature before training the ML algorithm allows you to increase the accuracy of the constructed model. © 2021 data Science in Oil and Gas 2021, DSOG 2021.

Electroencephalogram (EEG) signals are a valuable recording technique to diagnose neurological disorders and identify noninvasive biomarkers for clinical application, however, they are vulnerable to various artifacts. It is difficult to define exact parameters which efficiently distinguish artifacts from neural activity, and thus cleaning EEG data often relies on labor-intensive visual scoring methods. While signal processing techniques to remove artifacts exist, many state-of-the-art techniques are designed for multivariate signals, which can be challenging to implement in recording setups with few electrodes. We demonstrate how the spectral slope - a method previously used to distinguish between conscious states by linear regression of the logarithmic EEG power spectra - can also be used to identify epochs contaminated by recording artifacts in rat EEG recordings and propose this as a first pass artifact detection method. We computed the mean spectral slope for both 'clean' and 'noisy' epochs and compared the distributions among individual recordings to determine whether the decision threshold should be dynamic or fixed. We found no significant difference between the mean of these distributions and determined that a spectral slope threshold of -8 μv2/Hz was effective at identifying noisy epochs across all recordings. The accuracy of our method was evaluated against visually scored recordings and obtained an average accuracy, ROC AUC, F1 and Cohen Kappa score of 94.2%, 92%, 86.4%, and 83%, respectively, across all epochs. Our study contributes to the automation of EEG artifact detection by presenting a straightforward initial method for identifying contaminated epochs based on the spectral slope of a single EEG channel in rodent recordings. © 2023 IEEE.

With the huge amount of data collected from the web, it is hard to manually analyze and extract useful incites from tables, matrices, or rows of data. Therefore, we need a way to represent these data (maps or graphs) to analyze/interpret them. data visualization makes it easier to identify trends, patterns, and outliers with large datasets. data Analytics is used to analyze raw data to make conclusions about the information. In this paper, we tackled web scrapping strategies to get COvID-19 data from the web, and then we went through some data analysis and exploration using EDA. © 2021 IEEE.

OBJECTIvE: Polycystic ovary syndrome (PCOS) is regarded as one of the most common endocrine-metabolic disorders among women of reproductive age, characterized by the complexity of its etiology, the interplay of multiple factors, and its polygenic nature. This paper utilizes the rigorous research methodology of traditional Chinese medicine network pharmacology to conduct an in-depth exploration of the potential mechanisms of action of modified Siwu Decoction in the treatment of PCOS. METHODS:In this study, we first identified the key components of Siwu Decoction using the TCMSP database, and subsequently conducted a meticulous screening of potential targets utilizing the SwissTargetPrediction database. Relevant targets for polycystic ovary syndrome (PCOS) were comprehensively collected from multiple authoritative databases including GeneCards, Therapeutic Target database, OMIM, DisGeNET, and The Pharmacogenomics Knowledgebase. Subsequently, the overlapping portion of these two datasets was visually presented through a venn diagram and imported into the String database to construct a protein-protein interaction network. Using the plugin function of Cytoscape 3.10.1 software, we conducted an in-depth analysis of this network and successfully identified ten core targets. Furthermore, we employed tools provided by the DAvID database and the Microbiotics website to perform an extensive Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis on the overlapping genes. Additionally, to validate the specific interaction mechanism between drug components and targets, we conducted molecular docking experiments using AutoDockTools 1.5.6 ***: After analysis, we found that there are 290 common points between drug targets and disease-related targets. Further analysis using molecular docking technology revealed that the top ten crucial targets exhibit excellent intermolecular binding energy with drug active i

Sign language is a helpful visual technique that can be utilized by individuals who have difficulty communicating verbally. This language is used frequently by people as well. However, the vast majority of individuals don't understand sign language very well, and as a result, they frequently struggle when attempting to communicate with someone who is fluent in it. The community of people who have trouble speaking or hearing will benefit from an initiative called the Sign Language Recognition System. It is extremely challenging for deaf mutes to communicate, which is why we require a linguistic framework to understand what it is that they are attempting to express. In light of this, we present in this research an American Sign Language (ASL) handwriting translator that is built on convolutional neural networks. Instructing computers to recognize specific characters is one way to accomplish this goal. The Support vector Machine (SvM) and the Convolutional Neural Network are two types of artificial neural networks that are being utilized in our project we have suggest the identification of American Sign Language. In addition, the Decision Tree and voting Classifier are applied to the dataset in order to do an analysis. We have demonstrated the design and execution of an American Sign Language (ASL) translator that also incorporates fingerspelling as a direct consequence of this. © 2023 IEEE.

It is highly desirable yet challenging to generate image captions that can describe novel objects which are unseen in caption-labeled training data, a capability that is evaluated in the novel object captioning challenge (nocaps). In this challenge, no additional image-caption training data, other than COCO Captions, is allowed for model training Thus, conventional vision-Language Pre-training (vLP) methods cannot be applied. This paper presents visual vOcabulary pre-training (vIvO) that performs pre-training in the absence of caption annotations. By breaking the dependency of paired image-caption training data in vLP, vIvO can leverage large amounts of paired image-tag data to learn a visual vocabulary. This is done by pre-training a multi-layer Transformer model that learns to align image-level tags with their corresponding image region features. To address the unordered nature of image tags, vIvO uses a Hungarian matching loss with masked tag prediction to conduct pre-training. We validate the effectiveness of vIvO by fine-tuning the pre-trained model for image captioning. In addition, we perform an analysis of the visual-text alignment inferred by our model. The results show that our model can not only generate fluent image captions that describe novel objects, but also identify the locations of these objects. Our single model has achieved new state-of-the-art results on nocaps and surpassed the human CIDEr score.
