The Wave Nature of Light02:12

The Wave Nature of Light

61.6K
The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Doppler Effect - I00:56

Doppler Effect - I

6.5K
The Doppler effect and Doppler shift were named after the Austrian physicist and mathematician Christian Johann Doppler in 1842, who conducted experiments with both moving sources and moving observers. Consider an observer standing on a street corner, observing an ambulance with a siren sound passing by at a constant speed. The observer experiences two characteristic changes in the sound of the siren. Initially, the sound increases in loudness as the ambulance approaches and decreases in...

Doppler Effect - II01:05

Doppler Effect - II

4.8K
The Doppler effect has several practical, real-world applications. For instance, meteorologists use Doppler radars to interpret weather events based on the Doppler effect. Typically, a transmitter emits radio waves at a specific frequency toward the sky from a weather station. The radio waves bounce off the clouds and precipitation and travel back to the weather station. The radio frequency of the waves reflected back to the station appears to decrease if the clouds or precipitation are moving...

Genetic Material

3.8K
Within the human body, a complex and detailed system of trillions of cells works in unison to sustain life. Each cell houses a nucleus, which contains 46 chromosomes divided into 23 pairs. Chromosomes are highly coiled structures made of the genetic material DNA. These chromosomes are essential carriers of genetic information, with half inherited from the mother through her egg and the other half from the father's sperm, combining to create the unique genetic makeup of an individual.

Members Made of Elastoplastic Material

The behavior of elastoplastic materials under bending stresses, particularly in structural members with rectangular cross-sections, is crucial for predicting material responses and understanding failure modes. Initially, when a bending moment is applied, the stress distribution across the section follows Hooke's Law and is linear and elastic. This distribution means the stress increases from the neutral axis to the maximum at the outer fibers, up to the elastic limit.
As the bending moment...

Bending of Members Made of Several Materials

622
In analyzing a structural member composed of two different materials with identical cross-sectional areas, it is crucial to understand how their distinct elastic properties affect the member's response under load. The analysis involves assessing stress and strain distributions using the transformed section concept, which accounts for variations in material properties.
Hooke's Law determines stress in each material, stating that stress is proportional to strain but varies due to each material's...

Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Acoustics

Background:

  • Characterizing mechanical properties of layered media is crucial for understanding tissue biomechanics.
  • Non-invasive methods for assessing skin abnormalities require precise measurement of shear wave speeds.

Purpose of the Study:

  • To develop and validate a broadband surface-wave elastography technique for estimating shear wave speeds in multi-layered soft tissues.
  • To assess the method's accuracy in identifying embedded inclusions representing skin abnormalities.

Main Methods:

  • Utilized a scanning laser Doppler vibrometer (LDV) to measure surface waves generated by a piezoelectric transducer on a three-layer phantom.
  • Extended Rayleigh wave models for multilayered media to enable forward modeling and inversion for shear wave speed estimation.
  • Validated the method with in vivo measurements on human forearm skin.

Main Results:

  • The method accurately identified a stiff inclusion (1.5% error) within the layered phantom, mimicking a skin abnormality.
  • Estimated shear wave speeds for the surrounding layer with approximately 10% error, influenced by unmodeled viscoelastic effects.
  • Demonstrated feasibility and clinical relevance through successful in vivo measurements on human forearm skin.

Conclusions:

  • Broadband surface-wave elastography with LDV is a sensitive and adaptable method for characterizing mechanical properties of layered skin tissues.
  • The technique shows promise for diagnosing skin abnormalities and monitoring treatment response.
  • Further refinement can improve accuracy by incorporating viscoelastic models.
