    • Pressure gauge experiments in India 

      Joseph, A.; Desa, E.; Vijaykumar, K.; Desa, E.S.; Desai, R.G.P.; Prabhudesai, S.P. (UNESCO, 2004)
      Pressure measurements made in differing turbid water bodies and turbulent clear-water bodies have led to the inference that the effective mean-depth in situ density value, Row eff, of these water bodies is less than the ...
    • Role of Effective Density in improving the accuracy of bottom pressure based sea level measurements - A case study from Gulf of Guinea 

      Joseph, A.; Mehra, P.; Desai, R.G.P.; Dotse, J.; Odametey, J.T.; Nkebi, E.K.; Vijaykumar, K.; Prabhudesai, S.P. (Singapore: IEEE Singapore Section Secretariat, 2006)
      Seasonal observations of a set of bottom pressures and concurrent tide-staff measurements from Takoradi harbour located in the Gulf of Guinea indicated that the effective depth-mean density value, rho sub(eff) of this clear ...
    • Safety aspects for underwater vehicles
