Electronic Geometry Models
Reviewed collection of digital geometry models for research and education in mathematics. The geometry models in this archive cover a broad range of mathematical topics from geometry, topology, and to some extent from numerics. Examples are geometric surfaces, algebraic surfaces, topological knots, simplicial complexes, vector fields, curves on surfaces. All models are accompanied with a unique description. The most important models, the geometry jewels, are reviewed by the Zentralblatt fr Mathematik.

Teslaco
Optimum Power Conversion, Inc., d.b.a. TESLAco, is a hi-tech company specialized
in the custom design of high-efficiency and high-power-density power supplies for commercial, industrial, automotive,
medical, military, defense, and space applications. The efficiency is typically higher than 95% at 5V output over a
wide input voltage and power range. TESLAcos expertise lays in small designs while applying zero ripple techniques,
which eliminates the need for external filtering. Recent DC-DC converter designs have power ratings of 100W, 300W,
600W, 1KW and 2KW with output voltages of 3.3V, 5V, 12V, 15V, 24V and 48V in open frame chassis with convection
cooling only (no need for forced air cooling). TESLAco has also experience with AC-DC converter designs, i.e., Front
end Power Factor Correction circuits complying with EN61000-3-2. Compliance with safety and EMI / EMC standards is
part of our know-how. Courses in power electronics (topologies, magnetics and control) are taught by Dr. Slobodan Cuk,
Chairman of TESLAco and Professor at Caltech until the year 2000. TESLAco sells the three volume books 'Advances in
Switched-Mode Power Conversion'. Dr. Cuk has pioneered the Cuk-Converter topology, also known as Cukonverter, as well
as the Tesla converter topology, which is marketed under the name TESLAconverter Power. The 'World's COOLEST Converter'
is a trademark of TESLAco.
