The most informative methods in diagnostics of retinal pathological conditions are ophthalmoscopy, fluorescence angiography (FAG), optical coherence tomography (OCT) and optical coherence tomography with angiography (OCT-angiography, angio-OCT, OCT-A). This paper describes an algorithm of retinal pathologic focus formation based on optical coherence tomography (OCT) scans. The algorithm allows to create a volumetric model of the pathological focus within clinically significant boundaries by separate segmentation of each of the macular cube scans, extraction of the pathological focus point cloud and its reconstruction into a polygonal 3D model. Certain morphometric parameters extracted from such a model are important for better analysis of retinal pathology. This will allow the ophthalmologist to prescribe the appropriate type and amount of treatment to stabilize and improve visual functions.

Reconstruction of buildings inevitably entails improving the thermal protection of premises, however, the development of measures for the thermal insulation of the existing building structures is impossible without evaluation of thermal characteristics of these structures, primarily the resistence to heat transfer. Evaluation of the materials according to their characteristics reference is often not possible. The main causes is the lack of information about construction materials to the inner layers of the long-erected buildings. Arise a number of difficulties in conducting field surveys due to the practical absence of the stationary conditions. Heat flux on the surface can change simultaneously with changes in temperature, as walling have thermal inertia, and need some time to change the temperature distribution in the structure thickness. To determine the actual heat transfer resistance of enclosing structures must take into account the dynamics of change of temperature and heat flow on the surface of the enclosure. When determining the actual heat transfer resistance needs to consider the time distribution of heat waves through the walling.
