Buoyancy and Stability for Submerged and Floating Bodies01:11

Buoyancy and Stability for Submerged and Floating Bodies

In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

Echo

The human ear cannot distinguish between two sources of sound if they happen to reach within a specific time interval, typically 0.1 seconds apart. More than this, and they are perceived as separate sources.
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case, then the...

Area of Science:

  • Acoustics
  • Signal Processing
  • Underwater Communications

Background:

  • Deep water acoustic communication presents significant challenges due to signal attenuation and multipath propagation.
  • Long-range underwater data transmission requires robust modulation and coding schemes.

Purpose of the Study:

  • To investigate the feasibility of multi-carrier Orthogonal Frequency Division Multiplexing (OFDM) for long-range deep water acoustic communication.
  • To evaluate the performance of OFDM signals transmitted over distances up to 700 km.

Main Methods:

  • Conducted a long-range acoustic communication experiment in deep water using a towed source and a towed horizontal line array.
  • Transmitted multi-carrier OFDM signals with a 50 Hz bandwidth (225-275 Hz).
  • Employed beamforming, interleaver gain, and low-density parity-check (LDPC) coding to enhance signal reception and data integrity.

Main Results:

  • Achieved error-free communication at effective data rates of 15 bits/s at 550 km and 7.5 bits/s at 700 km.
  • Demonstrated successful data transmission using OFDM signals with a towed horizontal array in deep water.
  • Showcased the effectiveness of combining interleaver gain with LDPC coding for low signal-to-noise ratio environments.

Conclusions:

  • Multi-carrier OFDM is a feasible technology for long-range deep water acoustic communication.
  • The experimental results validate the use of towed arrays and advanced coding techniques for reliable underwater data transmission.
  • This study paves the way for future high-data-rate communication systems in challenging underwater environments.
