Force Classification01:22

Force Classification

Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...
Distributed Loads01:19

Distributed Loads

Distributed loads are a common type of load that engineers and scientists encounter in various practical situations. Distributed loads often refer to a type of load spread over a surface or a structure and can be modeled as continuous force per unit area.
For example, consider a bookshelf filled with books stacked vertically adjacent to each other. The weight of the books is evenly distributed over the length of the shelf. As a result, the pressure at different locations on the surface of the...
Distributed Loads: Problem Solving01:21

Distributed Loads: Problem Solving

Beams are structural elements commonly employed in engineering applications requiring different load-carrying capacities. The first step in analyzing a beam under a distributed load is to simplify the problem by dividing the load into smaller regions, which allows one to consider each region separately and calculate the magnitude of the equivalent resultant load acting on each portion of the beam. The magnitude of the equivalent resultant load for each region can be determined by calculating...
Mechanical Systems01:22

Mechanical Systems

Mechanical systems are analogous to to electrical networks where springs and masses play similar roles to inductors and capacitors, respectively. A viscous damper in mechanical systems functions similarly to a resistor in electrical networks, dissipating energy. The forces acting on a mass in such systems include an applied force in the direction of motion, counteracted by forces from the spring, a viscous damper, and the mass's acceleration. This interplay of forces is mathematically described...
Multimachine Stability01:25

Multimachine Stability

Multimachine stability analysis is crucial for understanding the dynamics and stability of power systems with multiple synchronous machines. The objective is to solve the swing equations for a network of M machines connected to an N-bus power system.
In analyzing the system, the nodal equations represent the relationship between bus voltages, machine voltages, and machine currents. The nodal equation is given by:

Area of Science:

  • Biomedical Engineering
  • Clinical Diagnostics
  • Speech-Language Pathology

Background:

  • Swallow kinematic analysis evaluates physiological swallowing attributes.
  • Videofluoroscopic swallowing studies (VFSS) are the gold standard but involve radiation.
  • High-resolution cervical auscultation (HRCA) is a radiation-free alternative, but comprehensive multitask analysis is unexplored.

Purpose of the Study:

  • To develop an integrated framework for comprehensive swallow kinematic analysis using HRCA signals.
  • To apply shared parameter multi-task learning with transformer encoders for this analysis.
  • To explore the application of HRCA for multitask swallowing assessment.

Main Methods:

  • Utilized shared parameter multi-task learning with transformer encoders.
  • Trained and evaluated the framework using HRCA signals from 120 patients, labeled by speech-language pathologists.
  • The framework analyzes multiple swallowing kinematics landmarks from individual swallows within HRCA signals.

Main Results:

  • Achieved 92% accuracy, 89% sensitivity, and 92% specificity in 10-fold cross-validation.
  • Maintained over 85% accuracy on an independent dataset, demonstrating strong generalization.
  • Outperformed state-of-the-art and baseline models for individual task detection in swallowing assessment.

Conclusions:

  • The multi-task framework provides detailed, objective analysis of key swallowing components (e.g., UES opening, laryngeal vestibule closure, hyoid displacement).
  • Performance is comparable to single-task algorithms and VFSS-based human ratings.
  • The comprehensive analysis aids speech-language pathologists in decision-making and diagnosing swallowing impairments.
