The evolution in space and time of localized high-energy electromagnetic wave packets, which take place in processes of radiation by ultra relativistic electrons is considered. It is shown that high energies make stabilizing influence on the motion of suc... see more

The anechoic chamber is closely related as a device for precisely measuring various acoustic characteristics. Anechoic chambers room conditions controlled to produce a sound field-free space. This study focused on testing various commercial wedges such as... see more

Hypersensitivity (electrical sensitivity) is a health problem due to the influence of electromagnetic wave radiation in the form of physiological disorders characterized by neurological symptoms (disorders of the brain and nervous system) and sensitivity ... see more

The problem of electromagnetic wave pressure on a thin conductive vibrator located in a rectangular waveguide is solved. Wave H10 falls on the vibrator. The vibrator is located perpendicular to the wide wall of the waveguide. The current in the vibrator a... see more

Many studies show that student worksheets can be suitable teaching materials to achieve learning objectives, whether at school or college. Also, college student worksheets can make it easier for students to learn computing-based lessons. This study aims t... see more

The article is devoted to the problem of wave-packet propagation in a three - layer hydrodynamic system "layer with a hard bottom - layer - layer with a cover stratified by density. The current research on selected topics is reviewed. The mathem... see more

The paper presents the results of the study of properties of fast surface electromagnetic waves that propagate along the flat interface between the active metamaterial and air (or vacuum). The case of homogeneous and isotropic metamaterial is conside... see more

Using the q-harmonic analysis associated with the q-Rubin operator, we study three types of q-wavelet packets and their corresponding q-wavelet transforms. We give for these wavelet transforms the related Plancherel and inversion formulas as well as their... see more

Background: Increased use of mobile phones has made users have to pay more attention to the side effects of cell phone use on human health. men who carry a cell phone in a pants pocket can reduce sperm productivity by 70% and even worse the sperm produced... see more
