Single-borehole imaging using gravity gradiometer data
We present a feasibility study for interpretation of gravity gradient surveys in a single borehole using both an analytic and inverse-based approach. We analytically solve for distance and direction angles to a point source using the components of the gravity gradient tensor from a set of observations in a single borehole. We then generalize this approach to include the response due to a prisma...
متن کامل3-D Inversion of gravity gradiometer data
We present the development of an algorithm for inverting multi-component gravity gradiometer data to recover three-dimensional (3-D) distributions of density contrast for salt imaging. The algorithm is a direct adaptation of the author’s earlier work on 3-D inversion of magnetic data. The underlying method is based upon a regularized inversion that constructs a density contrast distribution hav...
متن کاملAnalysis of Errors in Gravity Derived from the FALCON Airborne Gravity Gradiometer
FALCON airborne gravity gradient data can be converted to vertical gravity via direct integration techniques (Gunn, 1975) or equivalent source methods (Dampney, 1969), and hence compared with conventional gravimetry data. Either conversion process amplifies long wavelength features from the gravity gradient data and therefore makes regional scale features vulnerable to distortion. Recent FALCON...
متن کاملA Novel Intelligent Fault Diagnosis Approach for Critical Rotating Machinery in the Time-frequency Domain
The rotating machinery is a common class of machinery in the industry. The root cause of faults in the rotating machinery is often faulty rolling element bearings. This paper presents a novel technique using artificial neural network learning for automated diagnosis of localized faults in rolling element bearings. The inputs of this technique are a number of features (harmmean and median), whic...
متن کاملTensor Product Analysis of Partial Difference Equations
1. Introduction. This note presents a few of the results which we have obtained by applying a classical and fundamental idea to the analysis of certain partial difference equations. The idea is that certain multidimensional problems can be solved by solving a few one-dimensional problems—it is the basis of the classical method of separation of variables of mathematical physics. In the case of p...
