书籍 ForDummies_RFID_For_Dummies
With all the recent hype over radio frequency identification (RFID) and
the requirements to implement it, you might think that RFID can turn
water into wine, transform lead into gold, and cure the world’s diseases. You
might also be worried that RFID will enable Big Brother to track your move-
ment ...
书籍 A_Software-Defined_GPS_and_Galileo_Receiver
Software-defined radios (SDRs) have been around for more than a decade. The
first complete Global Positioning System (GPS) implementation was described
by Dennis Akos in 1997. Since then several research groups have presented their
contributions. We therefore find it timely to publish an up-to-date ...
书籍 Audio+Engineering
Sound is simply an airborne version of vibration. The air which carries sound is a mixture
of gases. In gases, the molecules contain so much energy that they break free from
their neighbors and rush around at high speed. As Figure 1.1(a) shows, the innumerable
elastic collisions of these high-speed ...
书籍 Practical Arduino Cool Projects
Phenomenon is an overused and overloaded term, but somehow it seems appropriate for Arduino—an
endeavor that has caught the attention of an astonishingly wide range of people and provided
opportunities for those who might otherwise have never picked up a soldering iron or written a single
line of c ...
书籍 DRM023_3-Phase AC Designer Reference Manual
This reference design describes the design of a 3-phase AC induction
vector control drive with position encoder coupled to the motor shaft. It
is based on Motorola’s DSP56F805 dedicated motor control device.
AC induction motors, which contain a cage, are very popular in variable
speed drives. They ...
书籍 Introduction to Dynamical Systems_Rainer Klages
There exist two essentially different approaches to the study of dynamical systems, based on
the following distinction:
time-continuous nonlinear differential equations ⇋ time-discrete maps
One approach starts from time-continuous differential equations and leads to time-discrete
maps, which are ob ...
书籍 MultivariableControlSystems
This introductory chapter is devoted to reviewing the fundamental ideas of
control from a multivariable point of view. In some cases, the mathematics
and operations on systems (modelling, pole placement, etc.), as previously
treated in introductory courses and textbooks, convey to the readers an un- ...
