Artifacts caused by intensely absorbing areas are encountered in computed tomography (CT) and may obscure or simulate pathology in medical applications, hide or mimic the cracks and cavities in the devices at industrial applications. We simulated sinograms with different levels of absorption to demonstrate the artifacts dynamics. If the analysis of the measured data shows the presence of strongly absorbing areas in the object under study we propose to use quadratic programming technique for solving the inverse problem. Although the technique is time-consuming it allows us to avoid the typical artifacts. We compare the images reconstructed with different techniques including the proposed one.

Digitalization has given rise to a substantially new civilizational and existential situation. The mankind development was associated with the creation of collective memory in the form of culture as a system for generating, storing and transmitting social experience, including the creation of an artificial environment. For the main part of history, man likened the world to himself, which made ...

This paper is a continuation of previous studies on the development of X-ray topotomography
using laboratory equipment. The results on the spatial location of a single polygonal
dislocation half-loop in a silicon single crystal were obtained as a result of testing the sensitivity of
the X-ray topo-tomo diffractometer. A comparison was made with high-resolution experimental data
obtained at the ...

Objective
Diffusion imaging techniques such as DTI and HARDI are difficult to implement in infants because of their sensitivity to subject motion. A short acquisition time is generally preferred, at the expense of spatial resolution and signal-to-noise ratio. Before estimating the local diffusion model, most pre-processing techniques only register diffusion-weighted volumes, without correcting for intra-slice artifacts ...

Под нанообъектами можно понимать артефакты (квантовый объект, классический объект), которые подчиняются некоторому математическому формализму, учитывающему специфику формализмов, связывающих между собой квантовые объекты, с одной стороны, и классические объекты, с другой. Подобные нанообъекты в чем-то схожи с интенциональными объектами, подразумевающими связь психических и реальных объектов. Если же обратиться к кондиционалам приписывания функции, то нанообъекты можно было ...

The graph partitioning problem is to partition the vertex set of a graph into a number of nonempty subsets so that the total weight of edges connecting distinct subsets is minimized. Previous research requires the input of cardinalities of subsets or the number of subsets for equipartition. In this paper, the problem is formulated as ...
