The problem of two‐dimensional, homogeneous, elliptical irregularities in an otherwise homogeneous plasma with anisotropic conductivity is considered. We find an analytic solution for the potential inside and outside the ...

The vignetting correction is one of first steps for the digital processing of images obtained from light and electron microscopy, being a determining factor for the quality of the results achieved by automatic methods ...

A three‐dimensional numerical simulation of plasma density irregularities in the postsunset equatorial F region ionosphere leading to equatorial spread F (ESF) is described. The simulation advances the plasma number density ...

Two different aspects of the effect of magnetic activity on the dynamics of equatorial spread F (ESF) irregularities are studied here using spaced receiver scintillation observations. The first one deals with the question ...

We investigate rotationally supported dwarf irregular (DIRR) galaxies as a new category of targets for indirect dark matter (DM) searches with gamma-ray telescopes. In the framework of pointlike analysis, pressure-supported ...

Until now the presence of F-region irregularities responsible for spread-F (sp-F) traces in ionograms has been considered as a purely night-time phenomenon extending sporadically lo the early morning hours. We here in ...

Large-scale (λ∼1 km) waves in the daytime and nighttime equatorial electrojet are studied using coherent scatter radar data from Jicamarca. Images of plasma irregularities within the main beam of the radar are formed using ...

This masters dissertation presents in greater level of details two of the most used methods for performing volume calculation for irregular solids: the blocks and subblocks method and the vector integration method. It ...

Is fundamental for any country's transport system (air, land and sea), the latter is an element of transcendence because currently 80% of world trade is run by shipping and over 50% of GDP (gross domestic product) comes ...
