This work is devoted to the theory of joint interpretation of multimethod geophysical data and its application to the solution of real geophysical inverse problems. The targets of such joint interpretation can be geological bodies with an established dependence between various physical properties that cause anomalies in several geophysical fields (geophysical multiresponse). The establishing of...

The surface autocorrelation function can be retrieved from the values of the far-field integrated irradiance. The inversion procedure is discussed in the frame of a theory of integrated wavelet transformation. For different types of autocorrelation functions, the capabilities and limitations of the inversion procedure are studied. The influence of experimental noise and the specific choice of t...

in gravity interpretation, inversion algorithms have been used widely over the years, but as the potential follows the gauss theorem, there are many equivalent source distributions that can produce the same known field. so to obtain a unique solution, suitable constraints should be introduced to the algorithm. during the last decades many authors have used several approaches to introduce a prio...

We describe the Wavelet-Vaguelette Decomposition (WVD) of a linear inverse problem. It is a substitute for the singular value decomposition (SVD) of an inverse problem, and it exists for a class of special inverse problems of homogeneous type { such as numerical di erentiation, inversion of Abel-type transforms, certain convolution transforms, and the Radon Transform. We propose to solve ill-po...

OBJECTIVE To describe the use of cervical inversion for postpartum hemorrhage (PPH) management during cesarean delivery for placenta previa accreta/increta. METHODS In a retrospective, descriptive study, data were reviewed for cases in which cervical inversion was used to manage PPH during cesarean delivery at a center in Zahedan, Iran, between July 2, 2011, and September 25, 2014. Cervical i...

helicopter-borne frequency-domain electromagnetic (hem) surveys are used extensively for mineral and groundwater exploration and a number of environmental investigations. to have a meaningful interpretation of the measured multi- frequency hem data, in addition to the resistivity maps which are provided in each frequency or for some particular depth levels, it is a necessity to have a suit...

The problem of inversion dynamic systems has become widespread while solving the problems control, identification, and measurement arising during design research electrical mechanical systems. Inverting is an effective way implementing disturbance control processes, as well in combined with a predictive model. analysis information sources showed that practical solution most problems, number dif...

A typical geoacoustic inversion procedure involves powerful source transmissions received on a large-aperture receiver array. A more practical approach is to use a single moving source and/or receiver in a low signal to noise ratio (SNR) setting. This paper uses single-receiver, broadband, frequency coherent matched-field inversion and exploits coherently repeated transmissions to improve estim...
