Root Mean Square

If in an experiment, data values have a probability of being both positive and negative, neither the arithmetic mean, the geometric mean, nor the harmonic mean can be used to calculate the central tendency of the data set. In particular, if the positive and negative values are equally likely, the arithmetic mean is close to zero.
For example, consider the velocity of gas molecules in a container. The gas molecules are moving in different directions, which might impart positive and negative...

Application of Integration: Problem Solving

The process of breathing involves the periodic intake and expulsion of air, known as the respiratory cycle, which typically lasts about five seconds. Modeling the volume of air inhaled into the lungs as a function of time provides insight into both the dynamics and efficiency of pulmonary ventilation. This volume is determined by integrating the airflow rate over time, which captures the cumulative effect of air entering the lungs.Sinusoidal Model of AirflowAirflow during respiration is not...

Applications of Integration to Find Hydrostatic Pressure

Hydrostatic force is a fluid's total force at rest on a surface. For a horizontal surface submerged at a fixed depth, the pressure is constant and calculated as the product of fluid density, gravitational acceleration, and depth. In the case of a vertical dam wall submerged in water, this force is not evenly distributed due to the increasing pressure with depth. This variation arises from the cumulative weight of the water above each point. Integration is used to account for the continuous...

Applications of Integration to Find Centers of Mass

84
Rotational equilibrium provides a natural framework for defining the center of mass of a system. For a plank balanced on a pivot with two unequal masses, equilibrium is achieved when the net torque about the pivot is zero. Torque is defined as the product of a force and its perpendicular distance from the pivot. When the torques due to all forces cancel, the pivot coincides with the center of mass of the system.For a system composed of several discrete point masses, the center of mass lies at...

Applications of Integration to Find Blood Flow

58
Blood flow through a cylindrical blood vessel can be mathematically described using the principles of laminar flow, a regime in which fluid moves smoothly in parallel layers. In this model, the velocity of the blood is not uniform across the cross-section of the vessel; rather, it varies with the radial distance from the center. The maximum velocity occurs along the central axis, decreasing progressively toward the vessel walls, where it reaches zero due to viscous drag.Approximating Blood...

Area of Science:

  • Navigation Systems Engineering
  • Estimation Theory
  • Control Systems

Background:

  • The Extended Kalman Filter (EKF) exhibits low accuracy in Strapdown Inertial Navigation System/Doppler Velocity (SINS/DVL) integrated navigation.
  • Taylor model linearization in EKF can lead to suboptimal filtering estimation.

  • To enhance the stability and reduce computational complexity compared to existing methods.

Main Methods:

  • Implemented a Square-Root Unscented Information Filter (SR-UIF).
  • Utilized state probability approximation instead of Taylor linearization.
  • Optimized parameter selection for computational efficiency.
  • Applied square-root transformation for matrix symmetry and positive definiteness.

Main Results:

  • SR-UIF demonstrated higher estimation accuracy than the Extended Kalman Filter (EKF).
  • SR-UIF achieved estimation accuracy comparable to the Unscented Kalman Filter (UKF).
  • SR-UIF exhibited lower computational complexity than the UKF.

Conclusions:

  • SR-UIF effectively improves estimation accuracy and stability in SINS/DVL integrated navigation.
  • The proposed SR-UIF offers a computationally efficient alternative to the UKF.
