Sediment Bearing Pressure Analysis using sediment classification techniques

Understanding the geology and geotechnical qualities of the seafloor necessitates a comprehensive examination of the surface sediment topography and composition. This is based on the categorization of sediments concept. Using sediment classification methods accurately determines the sediment-bearing pressure, strength, and stability of sediment layers required for offshore construction and exploration. Estimating sediment-bearing pressure at the…

3D Ambient Noise Mapping using Wittekind Model in Indian Ocean.

The dumping of dangerous chemical, physical, or biological pollutants into the water is only one aspect of pollution in the ocean. Both natural and man-made noise sources contribute to ocean ambient noise. The latter being strongly tied  to the maritime shipping sector, acoustic sources. How acoustic waves behave is a prospective area for in-depth research…

Duct-borne Noise & Vibration onboard Maritime Vessels for Underwater Radiated Noise Management

Noise & Vibration studies are one of the most important aspects of designing any dynamic system. Any machinery which has components having high inertia, rotating components, friction, losses and other random forces create excitations at various locations. Ducts are an excellent carrier of various types of vibrations which are created by these excitation forces and…

Backend Deployment of user Interace for Passive Sonar Simulator

The Graphical User Interface or GUI uses icons, menus and other visual indicator (graphics) representations to display information and related user controls, unlike text-based interfaces, where data and commands are in text. GUI makes computer operation more intuitive, and thus makes the interaction of users with the software easy. GUIs generally provide users with immediate,…
