<abstract><p>We study the properties of electronic circuits after linearization around a fixed operating point in context closed-loop stability analysis. When distributed elements, like transmission lines, are present circuit it is known that unstable can be created without poles complex right half-plane. This undermines existing analysis techniques determine by looking for half-pla...

this paper presents an exact analytical solution for two-dimensional conductive heat transfer in spherical composite pressure vessels .the vessels are in spherical shape and fibers are winded in circumferential direction. the analytical solution is obtained under the general boundary conditions which consist of convection, conduction and radiation inside/outside of vessel. the heat transfer equ...

One of the fundamental limits classical optical microscopy is diffraction limit resolution. It results from finite bandwidth transfer function (or OTF) an microscope, which restricts maximum spatial frequencies that are transmitted by a microscope. However, given frequency support OTF, fully determined used hardware, open and unsolved question what optimal amplitude phase distribution across th...
