Deformation congruence models form the basis for conventional deformation analysis
(CDA). In geometrical sense, these models connect an epochal object states—represented …

It is common practice to use the well-known concept of the minimal detectable bias (MDB) to
assess the performance of statistical testing procedures. However, such procedures are …

In this contribution, we propose a method for statistically evaluating the risk in a deformation
monitoring system. When the structure under monitoring moves beyond tolerance, the …

This paper proposes a method for determining the vertical deformations treated as random
fields. It is assumed that the monitored surfaces are subject not only to deterministic …

The paper analyses the possibility of increasing efficiency of the Iterative Weighted Similarity
Transformation (IWST) method, which is a prototype of classic robust methods, using global …

Nos últimos anos, houve acidentes de grandes proporções devido ao rompimento de
barragens no Brasil, o que motivou o aumento das pesquisas relacionadas à análise de …

Earth's surface velocities are routinely extracted from Global Navigation Satellite System
(GNSS) position time series. In addition to velocity estimates, acceleration may be a crucial …

In different Geodetic networks the observations are measured repetitively. These
observations, called original observations, are independent. At the design stage of the …

Customary confidence regions do not truly reflect in the majority of our geodetic applications
the confidence one can have in one's produced estimators. As it is common practice in our …

Abstract In Conventional Deformation Analysis (CDA), at least two different epochs are
adjusted by using the Least Squares Estimation (LSE) method and compared statistically …
