The iris structure motion is analyzed. Extension and compression of the iris structural elements are nonlinear with respect to the pupil radius change. To reveal this nonlinearity the Lucas-Kanade, Ho...
scanner provides the ability to detect the geometric 3D model of a building without any physical contact with the structure. Knowledge of the 3D model will give the opportunity to study the deformatio...

In this paper a method is presented which allows the measurement of deflections and torsion by means of the silhouette of an object in images. The method is based on a finite element description of a ...
Earthquake can pose earth-shattering health hazards to the natural slops and land infrastructures. One of the chief consequences of the earthquakes can be land sliding, which is instigated by durable ...
In this paper the application of a novel non-contact GBInSAR sensor to the measurement of daily deformations of an arch-gravity dam is described. The sensor, named IBIS, is a Ku-band interferometric r...
Historical maps often suffer significant deformations of their supporting material of any type. These deformations make it difficult to make an accurate reading of maps in its geometric and semantic c...
Satellite-based navigation requires precise knowledge of the structure of the transmitted signals. For GPS, accurate knowledge of the shape of the ranging codes is required to ensure no biases are int...
This paper describes the collection and analysis of real data from twenty-four current, nominally healthy GPS satellites in the context of the ICAO second-order step (2OS) fault model.
Satellite-based navigation requires precise knowledge of the structure of the transmitted signals.For GPS, accurate knowledge of the shape of the code correlation peaks is required to ensure no biases...
Signal deformations are caused by imperfections or faults in the signal generating hardware onboard the satellites.Left uncorrected, these can lead to range errors. Thus they need to be measured and u...
Nominal signal deformations are present in GNSS-GPS and WAAS-GEO satellite signals. They result in pseudorange errors, which in turn cause navigation errors for GNSS users. These navigation errors dep...
Predictions of the future performance of ARAIM users depend on a thorough understanding of the nominal performance of the satellites from all constellations. This generally requires long-term, careful...
Detecting the difference between two surfaces without the aid of control points is desirable for many industrial applications. We tackle this problem by means of robust surface matching. In presence o...
Chemical anchorages are applied in many engineering implementations, particularly strengthening of reinforced concrete structures. During strengthening procedure; chemical anchorages should be tested,...
