The data from low-flying satellites play both an independent and an additional role in the study of the ionosphere. In this paper, data from the Swarm satellite were used to assess the state of the ionosphere during the disturbance period of April 19-21,...

This paper deals with generalized ISAR geometry and image reconstruction technique. Two-dimensional (2-D) Inverse Synthetic Aperture Radar (ISAR) scenario is depicted in a two-dimensional radar signal registration plane. The arbitrary movement of the ...

The Spectral Airglow Structure Imager (SASI) is a mission on CubeSat NB’s VIOLET satellite, and it is imaging the 630 nm redline atomic oxygen airglow in the ionosphere at altitudes of 300-400 km. The image acquisition conditions of VIOLET make it ...

Disruptive Events (DE), such as disasters, virus outbreaks, and military conflicts, are often hugely affecting human life, and works featuring resilience against DE are receiving much attention. A key priority in this regard is the effective monitoring ...

Radios operating in a slowly fading channel require adaptive communication links that adjust to channel conditions that are not always ideal. Matching a communication link’s bit rate to the channel conditions is critical to maximize throughput. A ...

During operation, mobile phones emit energy in the form of electromagnetic fields that can be absorbed by the user's head. However, it is not yet clear whether this electromagnetic energy causes biological consequences or adverse effects on human ...

This paper presents the results of a study of the energy performance of the building of the Burgas Free University, as well as of a dwelling located in it. An analysis of the possibilities of a set of software products for determining the energy ...

This report presents the results of a study of the performance of small PV plants installed on buildings. The studied micro PV plants are built on the basis of two different technologies - monocrystalline and polycrystalline. The study aimed to ...
