There are several problems related to the properties of
the triangular mesh representation that describes a
surface of an object. Sometimes, the surface is represented
just as a set of triangles without any other
information and the STL file format, which is used for
data exchanges, is a typicalexam ...
Quality control of production has always been a necessity
in stainless steel mills. The users of stainless
steel set ever-increasing requirements on product
quality. Many material properties can still only be
measured in laboratory but more and more measurements
are now made on-line during the produ ...
An adaptive fuzzy integral sliding mode
controller for mismatched time-varying linear systems is
presented in this paper. The proposed fuzzy integral sliding
mode controller is designed to have zero steady state
system error under step inputs and alleviate the undesired
chattering around the sliding ...
Description
The art galleries of the new and very futuristic building of the Center for Balkan Cooperation have the form of polygons (not necessarily convex). When a big exhibition is organized, watching over all of the pictures is a big security concern. Your task is that for a given gallery to wri ...
We analyze, both analytically and numerically, the effectiveness
of cloaking an infinite cylinder from observations by electromagnetic
waves in three dimensions. We show that, as truncated approximations
of the ideal permittivity and permeability tensors tend towards
the singular ideal cloaking fiel ...
We obtained the energy transport velocity distribution for a three dimensional ideal cloak
explicitly. Near the operation frequency, the energy transport velocity has rather peculiar
distribution. The velocity along a line joining the origin of the cloak is a constant, while
the velocity approaches ...
The Schumann resonance frequencies are a set of eigenmodes in the extremely low frequency (ELF) portion of the electromagnetic field spectrum. These frequencies are only present for planetary-like bodies with a substantial ionosphere acting as a perfect electric conductor, thus forming a resonance c ...
