3D Soundscaping

Researchers at WSU have developed a 3D Soundscaping technology that enables one to take sound measurements to a new level by locating sound sources, visualize their resultant sound pressure fields in 3D space. In traditional sound sensing applications, sound is measured using microphones and sound pressure levels and spectra are measured at survey locations....

Guidance and Control System for Under Actuated Marine Surface Vessels

WSU researchers have developed a guidance system that yields a faster convergence rate of the ship to its desired trajectory than existing systems. The new algorithm varies the radius in the guidance algorithm exponentially as opposed to linear variations in existing schemes. This was done to prevent the system from over-reacting for small cross track...
