Shape optimization of the cylindrical shell with three types of directrix curves of the extremum of the
function. The results can be summarized as follows, firstly, for the cylindrical
shell Entropy of a self-gravitating electrically charged thin shell and the black hole limit for the
shell's entropy can be calculated. It is found that the
shell's entropy is generically a
function Engineering photonic nanojet by a graded-index micro-cuboid-maximum) of nanojets formed in the vicinity of dielectric core-
shell cuboids with different types of index
grading Entropy of a self-gravitating electrically charged thin shell and the black hole limit for the
shell's entropy can be calculated. It is found that the
shell's entropy is generically a
function On the stress state of thin-walled isotropic building constructions of the shell type isotropic shallow thin-walled
shell constructions is studied in the framework of S.P. Timoshenko shear model
