Machine Learning Simulation: Torso Dynamics of Robotic Biped
… to effectively control the swing-leg and torso of a 3 degree of freedom active dynamic bipedal walker in simulation. The model began each episode in a stationary vertical configuration. At each time-step the learning agent was rewarded for horizontal hip displacement scaled by torso …

Computation of Breast Ptosis from 3D Scans of Torso
… of breast ptosis using 3D scans of the torso. Experimental results suggest that 3D features are successful for objectively categorizing breast ptosis with high accuracy and precision.

Modeling torso imaging via time-domain diffuse correlation spectroscopy
… as a means of imaging bleeding within the torso. TD-DCS is a new, powerful imaging technique with primary application of measuring blood flow in the brain. Here we show both how this novel imaging technique can be expanded for use in other regions beyond the brain as well as how we …

Engineering Materials for Non-Compressible Torso Hemorrhage and Internal Bleeding
Non-compressible torso hemorrhage (NCTH) and internal bleeding results in a significant number of preventable casualties worldwide among civilians and in the field. In particular, internal bleeding can only be diagnosed through changes in vital signs and then through imaging modalities that may …

Vibrotactile pattern recognition on the torso : effects of concurrent activities
Vibrotactile displays have been created to aid vision or hearing through the sense of touch. These displays communicate with the user to provide information. The focus of this thesis was to determine how concurrent activity affects vibrotactile signal recognition. An overall accuracy recognition …

A Study of Carasaurus' (Dinosaura: Sauropodomorph) Torso and its Biomechanical Implications
… column has a slight double curve and the torso is more narrow and volumetrically smaller than previously reconstructed. The shape of the dorsal vertebrae series was based upon the position of the zygopophyses and centrum spacing. The dorsal ribs were placed on the vertebrae based upon the …

Biodynamic Analysis of Human Torso Stability using Finite Time Lyapunov Exponents
… life. Low back injury can result from a loss of torso stability causing excessive strain in soft tissue. This investigation seeks to apply existing methods to new applications and to develop new methods to assess torso stability. First, the time series averaged finite time Lyapunov exponent is …

Empirical Evaluation of Models Used to Predict Torso Muscle Recruitment Patterns
… The participants resisted loads applied to their torso via a harness. Results showed the models performed poorly (average R2's in the 0.40's), indicating that further improvements are needed in our current low back muscle activation modeling techniques. Considerable discrepancies were found …

Vibrotactile pattern recognition on the torso with one and two dimensional displays
… of vibrating motors (tactors) was mounted on the torso while the subject wore an Interceptor Body Armor (IBA) vest. Subjects were required to identify which of eight patterns was presented. The results indicated that subjects could recognize the patterns presented with perfect accuracy, which …

Dynamics of the human head and torso during activities that require stable vision
The dynamics of the head and torso during activities that require clear vision is a topic that has previously been studied. These studies have examined the relationships between the angular velocities of the head in pitch and yaw in activities that either require clear vision or do not. However, …

Experimental and Simulation Based Dynamic Assessment of Flexion and Extension Movements of Torso
… movements are studied in this dissertation. Torso muscle fatigue is known to affect the neuromuscular muscle recruitment that influences spinal stability. The first part of this dissertation investigates the effect of muscle fatigue on the stability of dynamic trunk flexion-extension …

3D Torso Image Retrieval of Prior Patients Cases for Enhancing Consultation about Breast Reconstruction Surgery
… dissertation introduces a novel system of 3D torso image retrieval, aimed at enhancing consultation process for breast reconstruction surgeries. The developed method integrates suggestive contours, the structure tensor, and mesh simplification using MeshCNN for 3D model retrieval. By coupling …

The effect of a commercially available abdominal support belt on torso posture, lift strength, and spinal compression
… in flexion and lateral bending angle of the torso across Belt conditions. Axial twist angle between the shoulders and the hips was also investigated. Strength data was collected through a force platform across three orthogonal axes. Spinal compression was predicted through the use of the …

Passive Stiffness Characteristics of the Scoliotic Lumbar Torso in Trunk Flexion, Extension, Lateral bending, and Axial Rotation
… surgery participated in three different tests (torso lateral side bending, torso axial rotation, and torso flexion/extension) that isolated mobility to the in vivo lumbar spine. Scoliotic individuals with Cobb angles ranging 15-75 degrees were accepted. Applied torque was measured using a …

Muscle Fatigue during Isometric and Dynamic Efforts in Shoulder Abduction and Torso Extension: Age Effects and Alternative Electromyographic Measures
… intermittent efforts in shoulder abduction and torso extension at different contraction levels. Two age groups were involved (n=24 in each), representing the beginning and end of working life. Findings from this study demonstrated that the older group exhibited slower progressions of fatigue, …

The Effect of Balance-Based Torso-Weighting on Mobility, Gait, Balance, Postural Control, and Falls Efficacy in Mobility Limited Older Adults
… fall risk among older adults. Balance-Based Torso-Weighting (BBTW) is a non-exercise intervention that improves functional measures among adults with multiple sclerosis, yet the effectiveness of BBTW has not been assessed among older adults without progressive neurological disorders. We …

A tactile communication system for navigation
… has been designed and evaluated. The arm and the torso, which offer relatively large and flat surface areas, were chosen as locations for the displays. The ability of subjects to identify patterns of vibrotactile stimulation on the arm and torso was tested in a series of experiments using the …
