Cartesian Vector Notation01:28

Cartesian Vector Notation

1.5K
Cartesian vector notation is a valuable tool in mechanical engineering for representing vectors in three-dimensional space, performing vector operations such as determining the gradient, divergence, and curl, and expressing physical quantities such as the displacement, velocity, acceleration, and force. By using Cartesian vector notation, engineers can more easily analyze and solve problems in various areas of mechanical engineering, including dynamics, kinematics, and fluid mechanics. This...

Steady State Concentration01:05

Steady State Concentration

5.9K
A steady state refers to the level of a drug in the body once it has reached an equilibrium between administration and elimination. It represents the point at which the drug administration rate equals the drug elimination rate, resulting in a relatively constant concentration in the body over time. The dynamic equilibrium is crucial to ensure the drug's effectiveness with minimal risk of toxicity.
Most drugs are administered in repeated doses at fixed intervals or through continuous...

Steady Flow of a Fluid Stream

688
Consider a control volume, such as a pipe with solid boundaries, through which fluid flows and changes direction due to the impulse exerted by the resulting force from the pipe walls. In steady flow, the mass of fluid entering the control volume at a given time, t, with velocity v1, is equal to the mass leaving after infinitesimal time dt, with velocity v2.
During this process, the momentum of the fluid within the control volume remains constant over the time interval dt. By applying the...

Cartesian Form for Vector Formulation01:26

Cartesian Form for Vector Formulation

1.1K
The Cartesian form for vector formulation is a process to calculate  the moment of force using the position and force vectors. The moment of force is defined as the cross-product of these vectors, making it a vector quantity. The Cartesian form of the position and force vectors involves unit vectors, which can be used to express the cross-product in determinant form.

Vector Components in the Cartesian Coordinate System

27.1K
Vectors are usually described in terms of their components in a coordinate system. Even in everyday life, we naturally invoke the concept of orthogonal projections in a rectangular coordinate system. For example, if someone gives you directions for a particular location, you will be told to go a few km in a direction like east, west, north, or south, along with the angle in which you are supposed to move. In a rectangular (Cartesian) xy-coordinate system in a plane, a point in a plane is...

Transient and Steady-state Response01:24

Transient and Steady-state Response

521
In control systems, test signals are essential for evaluating performance under various conditions. The ramp function is effective for systems undergoing gradual changes, while the step function is suitable for assessing systems facing sudden disturbances. For systems subjected to shock inputs, the impulse function is the most appropriate test signal.
These test signals are integral in designing control systems to exhibit two key performance aspects: transient response and steady-state...

Area of Science:

  • Magnetic Resonance Imaging (MRI)
  • Medical Physics

Background:

  • Balanced steady-state free precession (bSSFP) is a common MRI technique.
  • Intrinsic fat suppression is crucial for many MRI applications.

  • To address ghosting/aliasing artifacts observed in prior 2D FISS methods.
  • To optimize FISS parameters for enhanced fat suppression and image quality.

Main Methods:

  • Extended FISS to 3D Cartesian imaging, incorporating countermeasures for artifacts.
  • Investigated key parameters: dummy prepulses, spatial resolution, and interruption rate.
  • Utilized extended phase graph simulations and validated in phantom and in vivo 1.5T MRI studies.

Main Results:

  • Achieved homogeneous and consistent fat suppression across upper thigh angiography, abdominal imaging, and free-running 5D CINE.
  • Recovered obscured vessel structures in thigh angiography compared to bSSFP.
  • Reduced fat-related motion aliasing and improved image quality in cardiac CINE.
