... source and receiver points are determined explicitly using the equation derived by variational principle. The velocity profile is improved iteratively using the dumped least square method until the error between calculated and measured travel time converges within a required limit. The applicability...

... amplifiers. The receiving transducer is mounted to a three dimensional positioning system. The multi-purpose set-up is suitable for transmission as well as refraction measurements. A borehole simulator was constructed to simulate the acoustic response of the rock in boreholes. It is a triaxial cell in which...
