EZW Embedded Zero-tree Wavelets Encoding,video codecs from the EZW family which use a 3D version of EZW or SPIHT algorithms showed better performance than the MPEG-2 compression algorithm. These algorithms have many advantages inherent for wavelet based schemes and EZW-like coders. Their most important advantages are good compression performance and scalability.

In this paper we describe a control methodology for
catching a fast moving object with a robot manipulator,
where visual information is employed to track the
trajectory of the target. Sensing, planning and control
are performed in real-time to cope with possible
unpredictable trajectory changes of the moving target,
and prediction techniques are adopted to compensate the
time delays introduced by visual processing and by the
robot controller. A simple but reliable model of the
robot controller has been taken into account in the
control architecture for improving the performance of the
system. Experimental results have shown that the robot
system is capable of tracking and catching an object
moving on a plane at velocities of up to 700 mm/s and
accelerations of up to 1500 mm/s2.

The P89LPC938 is a single-chip microcontroller, available in low cost packages, based on
a high performance processor architecture that executes instructions in two to four clocks,
six times the rate of standard 80C51 devices. Many system-level functions have been
incorporated into the P89LPC938 in order to reduce component count, board space, and
system cost.

A few short years ago, the applications for
video were somewhat confined—analog was
used for broadcast and cable television, VCRs,
set-top boxes, televisions and camcorders.
Since then, there has been a tremendous and
rapid conversion to digital video, mostly based
on the MPEG-2 video compression standard.
Today, in addition to the legacy DV,
MPEG-1 and MPEG-2 audio and video com-
pression standards, there are three new high-
performance video compression standards.
These new video codecs offer much higher
video compression for a given level of video
quality.

M3GExport enables developers to export complex 3D animated scenes from Maya® directly to Mobile 3D Graphics file format (M3G), the emerging 3D file format for mobile 3D games.
Created by the developers of JBenchmark3D - the leading performance measurement tool for mobile 3D graphics, M3GExport lets use sophisticated features of M3G format like skeletal animation, morphing meshes, triangle stripping and other useful optimisations.
M3GExport for Maya is available in two editions, Limited and Standard.
The Standard version contains sophisticated optimisation options used mostly by commercial game developers.

一篇關(guān)于TCP-Vegas的文獻(xiàn):Vegas is an implementation of TCP that achieves between 37 and 71％ better throughput on the Internet, with onefifth to one-half the losses, as compared to the implementation of TCP in the Reno distribution of BSD Unix. This paper motivates and describes the three key techniques employed by Vegas, and presents the results of a comprehensive experimental performance study—using both simulations and measurements on the Internet—of the Vegas and Reno implementations of TCP.

The MIPS32® 4KEm™ core from MIPS® Technologies is a member of the MIPS32 4KE™ processor core family. It is a
high-performance, low-power, 32-bit MIPS RISC core designed for custom system-on-silicon applications. The core is
designed for semiconductor manufacturing companies, ASIC developers, and system OEMs who want to rapidly integrate
their own custom logic and peripherals with a high-performance RISC processor. It is highly portable across processes, and
can be easily integrated into full system-on-silicon designs, allowing developers to focus their attention on end-user
products. The 4KEm core is ideally positioned to support new products for emerging segments of the digital consumer,
network, systems, and information management markets, enabling new tailored solutions for embedded applications.

螺旋槳PID控制
In response to constant pressure to design more efficient, faster, smaller, and better systems, engineers are constantly looking for ways to improve existing designs or replace them with better ones. Facing large fuel costs, the aerospace industry in particular has been researching alternative designs to increase fuel efficiency and performance. One such alternative is the development of reconfigurable aircraft wings. These wings would be able to adapt to the current environment increasing lift or reducing drag when appropriate.

The DHRY program performs the dhrystone benchmarks on the 8051.
Dhrystone is a general-performance benchmark test originally
developed by Reinhold Weicker in 1984. This benchmark is
used to measure and compare the performance of different
computers or, in this case, the efficiency of the code
generated for the same computer by different compilers.
The test reports general performance in dhrystones per second.
Like most benchmark programs, dhrystone consists of standard
code and concentrates on string handling. It uses no
floating-point operations. It is heavily influenced by
hardware and software design, compiler and linker options,
code optimizing, cache memory, wait states, and integer
data types.
The DHRY program is available in different targets:
Simulator: Large Model: DHRY example in LARGE model
for Simulation
Philips 80C51MX: DHRY example in LARGE model
for the Philips 80C51MC
