Abstract:

This paper is devoted to proving two goals, to show that various depth sensors can be used to record breathing rate with the same accuracy as contact sensors used in polysomnography (PSG), in addition to proving that breathing signals from depth sensors have the same sensitivity to breathing changes as in PSG records. The breathing signal from depth sensors can be used for classification of sleep apnea events with the same success rate as with PSG data. The recent development of computational technologies has led to a big leap in the usability of range imaging sensors. New depth sensors are sm

Abstract:

Practicing breathing exercises is crucial for patients with chronic obstructive pulmonary disease (COPD) to enhance lung function. Breathing mode (chest or belly breathing) and lung volume are two important metrics for supervising breathing exercises. Previous works propose that these metrics can be sensed separately in a contactless way, but they are impractical with unrealistic assumptions such as distinguishable chest and belly breathing patterns, the requirement of calibration, and the absence of body motions. In response, this research proposes DeepBreath, a novel depth camera-based breat

Abstract:

Maximum diving depths and durations were examined in relation to body mass for birds, marine mammals, and marine turtles. There were strong allometric relationships between these parameters (log10 transformed) among air-breathing vertebrates (r = 0.71, n = 111 for depth; r = 0.84, n = 121 for duration), although there was considerable scatter around the regression lines. Many of the smaller taxonomic groups also had a strong allometric relationship between diving capacity (maximum depth and duration) and body mass. Notable exceptions were mysticete cetaceans and diving/flying birds, which disp

Abstract:

We tested the hypothesis that fish capable of bimodal respiration would respond to the increased travel costs of surfacing by decreasing their frequency of air breathing. Honey gouramis were permitted to move freely in a 220 cm deep aquarium, but their preferred depths were manipulated by changing the location of shelter and feeding sites. With increased depth the interval between air breaths increased. This supports the argument that travel to and from the surface is a significant cost for air-breathing fish. It provides evidence that respiratory behavior can be affected by factors not direct

Abstract:

Depth imaging has, through recent technological advances, become ubiquitous as products become smaller, more affordable, and more precise. Depth cameras have also emerged as a promising modality for activity recognition as they allow detection of users’ body joints and postures. Increased resolutions have now enabled a novel use of depth cameras that facilitate more fine-grained activity descriptors: The remote detection of a person’s breathing by picking up the small distance changes from the user’s chest over time. We propose in this work a novel method to model chest elevation to robustly m

Abstract:

This work analyzes and presents theoretical performance of a marine water-breathing ramjet propulsor. A conceptual scheme of the motor is shown, the equation of thrust is presented, and the dependence on cruise velocity and depth are discussed. Different propellant compositions, representing a wide variety of formulations suitable for propelling a water-breathing ramjet, are investigated. The theoretical results reveal that the specific impulse of a water-breathing ramjet can increase by as much as 30% compared to a standard rocket, when using a conventional hydroxyl terminated polybutadiene (

Abstract:

Chronic bronchitis is an inflammatory disease of the bronchial respiratory tract that lasts more than 3 months or several times in 2 years. Symptoms in patients with chronic bronchitis can affect breathing patterns, including dyspnea, respiratory frequency, depth of breathing, and oxygen saturation. Providing Pursed Lip Breathing therapy can create resistance to the air coming out of the lungs and open the airways to improve breathing patterns. This study aimed to analyze the effectiveness of Pursed Lip Breathing therapy on breathing patterns in patients with chronic bronchitis. This descripti

Abstract:

In this paper a wavelet spectrum technique for monitoring the breathing crack phenomenon of a beam-like bridge subjected to moving vehicle is presented. The stiffness of element with a breathing crack is modeled as a time dependent stiffness matrix using the finite element method. The stiffness matrix of the structure at each moment depends on the curvature of the structure at the crack position. The breathing crack phenomenon can be detected by analysing the instantaneous frequency (IF) of the system using the wavelet spectrum. When the crack depth is large, the crack area might be determined

Abstract:

Resuscitation in trauma patients is a critical component of emergency medical care that can mean the difference between life and death. Trauma patients often suffer from severe injuries that can result in significant blood loss, shock, and organ damage. Prompt and effective resuscitation is essential to stabilize the patient and prevent further complications. One of the key principles of resuscitation in trauma patients is the concept of the ""Golden Hour."" This refers to the critical window of time following a traumatic injury during which prompt medical intervention can greatly improve the
