a filter, the system converts this barcode
into a series of digital bits – “0” and “1”.
All that’s left is for the system to compare
these strings of figures with those in its
memory to distinguish between two individuals.
The market for this technology
is still emerging.
There are other biometric techniques,
including those based on DNA, but they
are still relatively insignificant in the
market.
The basic principle behind fingerprint,
iris and facial recognition systems is well
known, but each manufacturer has its
own secret technology recipe, which it
keeps under lock and key! ■

SAMCEF Rotor
SAMCEF Rotor is a general Finite
Element solution specifically adapted
to rotating machine analysis.
Rotor Dynamics Analysis
SAMTECH, Integrating CAE towards Professional Solutions
ABOUT SAMTECH
Founded in 1986 from the Aerospace Laboratory of University of Liège to allow
the development and commercialisation of the general purpose Finite Element
Analysis package SAMCEF, SAMTECH is now the leading European Company for
the development of Integrated CAE Solutions. SAMTECH provides its expertise to
industries like SNECMA, AIRBUS, EADS, ALENIA, ESA, SONACA, ABB, PSA, …
willing to increase their competitiveness by decreasing design time and costs and
optimizing their methodologies. In order to answer this objective, SAMTECH has
structured its competences around two main complementary activities:
- The “Software edition” activity which includes the development of
scientific software tools like the general FEA package SAMCEF, EUROPLEXUS
for explicit analysis or the open object oriented optimization platform BOSS
quattro.
- The “Engineering services” activity which provides customized solutions
such as consultancy, intellectual services and on-the-road projects. It includes
also assistance to prime contractors and high-tech subcontracts to
engineering offices, which belongs to industries, as well.
3-D MODEL
Rotors can also be modeled by
3-D shell or volume finite
elements. This model allows
describing rotors with complex
shape like impellers or fan. It is
possible to mix the 3-D model with the
beam model.
SAMCEF Rotor is a solution specifically
adapted to the dynamic analysis of structure
containing rotating components. It is finite
element based and allows to compute critical
speeds, stability, harmonic and time-transient
response of mechanical systems made of
rotating parts, fixed parts and linking devices.
