Walking Speed Estimation From a Wearable Insole Pressure System Embedded With an Accelerometer Using Bayesian Neural Network
(The American Society of Mechanical Engineers (ASME), 2021)In this study, we introduced a machine learning method for estimating human walking speed using plantar pressure and acceleration data. A pressure-derivative method using pretest feature selection was proposed to extract ... -
Palpation Sensitivity of an Embedded Nodule Using the Finite Element Method
(The American Society of Mechanical Engineers (ASME), 2021)A physician palpates a tissue to detect an embedded tumor nodule by sensing an increase in local tissue stiffness and nodule size. The Hertz contact model, however, is unable to predict the material or physical properties ... -
The Effect of Physical Activity on Residual Limb Volume, Comfort, and Gait Symmetry of Transfemoral Amputees
(The American Society of Mechanical Engineers (ASME), 2021)For lower limb amputees, the socket fit is affected by the physical activity performed during the day. The majority of the studies in this field include only transtibial amputees and do not examine the effects of this ... -
Human Thoracolumbar Spine Tolerance to Injury and Mechanisms From Caudo-Cephalad Loading: A Parametric Modeling Study
(The American Society of Mechanical Engineers (ASME), 2021)The aims of this investigation were to delineate the internal biomechanics of the spine under vertical impact vector and assess the probability of injury. Male and female whole-body human finite element models were used. ... -
Multiple Regression Analysis of Hip Fracture Risk Assessment Via Finite Element Analysis
(The American Society of Mechanical Engineers (ASME), 2021)An accurate assessment of hip fracture risk requires a proper consideration of parameters affecting the fracture. In general, hip fracture is assessed based on bone mineral density (BMD) and load amount, but hip fracture ... -
On the Transversely Isotropic, Hyperelastic Response of Central Nervous System White Matter Using a Hybrid Approach
(The American Society of Mechanical Engineers (ASME), 2021)A numerical and experimental hybrid approach is developed to study the constitutive behavior of the central nervous system white matter. A published transversely isotropic hyperelastic strain energy function is reviewed ... -
Effect of Die Clearance on Peak Punching Force During Cryogenic Micropunching of Polycaprolactone
(The American Society of Mechanical Engineers (ASME), 2020)Microscale holes were punched at cryogenic conditions in polycaprolactone (PCL) membranes to create synthetic three-dimensional (3D) tissue scaffolds through multilayer stacking of two-dimensional (2D) porous membranes. ... -
Convection-Enhanced Arborizing Catheter System Improves Local/Regional Delivery of Infusates Versus a Single-Port Catheter in Ex Vivo Porcine Brain Tissue
(The American Society of Mechanical Engineers (ASME), 2020)Standard treatment for glioblastoma is noncurative and only partially effective. Convection-enhanced delivery (CED) was developed as an alternative approach for effective loco-regional delivery of drugs via a small catheter ... -
Pulsatile Aortic Blood Flow—A Critical Assessment of Boundary Conditions
(The American Society of Mechanical Engineers (ASME), 2020)Patient specific (PS) blood flow studies have become popular in recent years but have thus far had limited clinical impact. This is possibly due to uncertainties and errors in the underlying models and simulations setup. ... -
Magnetic Resonance Image Based Computational Modeling for Anterior Cruciate Ligament Response at Low Knee Flexion Angle
(The American Society of Mechanical Engineers (ASME), 2020)A three-dimensional (3D) finite element (FE) human knee joint model developed from magnetic resonance images (MRIs) has been validated with the sets of experimental results in a normalized scale. The performance of the 3D ... -
Clinical Infrared Imaging in the Prone Position for Breast Cancer Screening—Initial Screening and Digital Model Validation
(The American Society of Mechanical Engineers (ASME), 2020)Breast cancer is the most prevalent form of cancer in women with over 266,000 new cases diagnosed every year in the United States. The various methods used for breast cancer screening range in accuracy and cost; however, ... -
Computational Modeling of Blunt Impact to Head and Correlation of Biomechanical Measures With Medical Images
(The American Society of Mechanical Engineers (ASME), 2020)Mild traumatic brain injury (TBI) is a common injury to service members in recent conflicts. We attempt to correlate simulation results with clinical data from advanced imaging techniques to identify TBI-related subtle ... -
Real-Time Bradycardia Prediction in Preterm Infants Using a Dynamic System Identification Approach
(The American Society of Mechanical Engineers (ASME), 2020)Chronic bradycardia, or slowing of heart rate, is common in preterm infants, and may often lead to neuropsychiatric disorders, developmental problems, and impaired cognitive functions in the long term. Therefore, early ... -
Two Methods to Assess Aortic Compliance Using Blood Pressure and Pulse-Wave Velocity
(The American Society of Mechanical Engineers (ASME), 2020)Aortic compliance has been well established as an independent predictor of cardiovascular morbidity and mortality. The current “gold standard” for assessing aortic compliance is to use the carotid-femoral pulse-wave velocity ... -
Design of a Novel Head Support for People With Hypermobile-Type Ehlers–Danlos Syndrome
(The American Society of Mechanical Engineers (ASME), 2020)Hypermobile-type Ehlers–Danlos Syndrome (hEDS) is characterized by connective tissue laxity resulting in excessive joint mobility. This can lead to instability of the cervical spine resulting in spinal cord compression and ... -
An Experimental Investigation of Forces on Cortical Bone in Deep-Hole Bone Drilling
