Long-term non-invasive sleep stage monitoring is instrumental in comprehending the progression of disorders, cardiovascular diseases, and interplay between sleep, type 2 diabetes, neurodegenerative diseases. However, conventional deep learning approach susceptible to personal attributes (PAs) such as age, Body Mass Index, severity apnea existing training dataset, potentially hindering its generalisation capacity unseen cohorts. This paper introduces DSleepNet, a novel that disentangles...

Introduction: The heterogeneity in tumours poses significant challenges to the accurate prediction of cancer stages, necessitating expertise highly trained medical professionals for diagnosis. Over past decade, integration deep learning into diagnostics, particularly predicting has been hindered by black-box nature these algorithms, which complicates interpretation their decision-making processes. Method: This study seeks mitigate issues leveraging complementary attributes found within...

Human activity recognition (HAR) is one of the core research themes in ubiquitous and wearable computing. With shift to deep learning (DL) based analysis approaches, it has become possible extract high-level features perform classification an end-to-end manner. Despite their promising overall capabilities, DL-based HAR may suffer from overfitting due notoriously small, often inadequate, amounts labeled sample data that are available for typical applications. In response such challenges, we...

The support vehicles of coal mine belt horizontal extension application new materials, is to change the traditional machinery "rough" and stupid" feature make it more light, green environmental protection. First introduced overall structure supporting which leads working environment vehicles, then comparison materials vehicle body, trying replace with for static mechanics fatigue analysis, we found body after life less than ideal requirements, thus try use car laser coating technology...

At present, many coal mines in underground loading method are: first we will fill with the tramcar, and then push tramcar to another one. Finally, electric locomotive take all away. This has brought problems: demand of roadway widened, transmission efficiency is low, high cost, labor intensive. To resolve these problems, put forward a kind application mine machinery--horizontal extension transfer machine. article describes loader part structure working principle. Green design principles,...

Coal mine horizontal belt extension transfer machine is designed in order to solve the loading efficiency not high, especially most mechanical failed continuous problem. Among them, tractor as power provide machine, its importance cans be imagined. Through statics analysis of frame, we draw conclusion: Preliminary plan too conservative given frame size, heavier, cause material waste, processing difficult. We will through two aspects size parameters optimization and design, make on premise...

In order to solve the problems such as delay and jitter in transmission of medium long distance satellite signals, well capacity, switching number ports optical crossover capability caused by multiple high rate channels, a signal scheme based on baseband resource pool was proposed this paper. Firstly, through OTN device, intelligent function is introduced increase reduce delay. On basis, technology used construct large-scale cross network, then realized dynamic sharing allocation processing...

Human sleep must be carefully monitored due to its impact on health. Typically, time series data for monitoring is multimodal, simultaneous, and continuous. Pre-training models based self-supervised learning can identify internal patterns without requiring external labelling. In this paper, we propose temporal neighbourhood-based pre-training multi-modality signals, including EEG, EOG, Heart Rate Variability (HRV). Two neighbourhood formation approaches are 1) the stationarity or...

Background: Ensemble tree-based models such as Xgboost are highly prognostic in cardiovascular medicine, measured by the Clinical Effectiveness Metric (CEM). However, their ability to handle correlated data, hospital-level effects, limited. Objectives: The aim of this work is develop a binary outcome mixed effects (BME) model that integrates random at hospital level. To ascertain how well handles data outcomes, we aims assess its performance and compare it fixed traditional logistic...

The motion sensing interactive devices can greatly enhance the sense of immersion.In this paper, flow interaction with HTC Vive is sums up five step.Analyzes positioning principle Lighthouse and introduce function thumbstick.Then defines quaternion, obtains quaternion changed state from helmet thumbstick in real world.Calculates visual angle picked model rotation virtual world according to world.Moreover designs multi person cooperative based on object model.Finally an simulation system...

Based on the ANSYS Software Ho-type cutting pick of Spiral Drum Shearer applied lasers coating is feasible analysis. At first paper describes Shearer’s overall body and elicit to its traditional materials. Then analysis head Cutting pick’s materials in order apply with coating. simulate it Fatigue calculation by Software. By found that life can develop well. So has a nice economic Potential.

This paper analyzes the common faults of YMZ light silt coal car loader's hoisting device in working process, and supplies several solutions; Simultaneously, it mainly introduces two types manufacturing technique about device's parts design improvement practical application appraises effect green device; The article concludes that improved workpiece performance is great value; As designers are designing products, only when they should combine new concept mode thinking with , attach...

Coal mine horizontal belt extension transfer machine is designed in order to solve the loading efficiency not high; especially most mechanical failed continuous problem. This can also load a whole column tramcars and without modification with direct use, improve obviously. paper first introduces structure working process, its important part tractor, main function; Then as force of tractor parts, we frame for stress analysis, set up 3-D model; Finally put model into ANSYS statics according...

Nowadays environmental issues facing society is one of the three major problems, deterioration environment for human survival and development caused a serious threat. The design moving part silt coal loader confined to traditional but seldom considering elements. Through analysis walk pattern characteristics existing from angle impact on environment, puts forward green thought. Based thought, all should be respectively designed detailed. includes material selection, recycling design,...
