Many of the pattern fi nding algorithms such as decision tree, classifi cation rules and clustering
techniques that are frequently used in data mining have been Developed in machine learning
research community. Frequent pattern and association rule mining is one of the few excep-
tions to this tradition. The introduction of this technique boosted data mining research and its
impact is tremendous. The algorithm is quite simple and easy to implement. Experimenting
with Apriori-like algorithm is the fi rst thing that data miners try to do.
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
These routines model tropospheric radiowave propagation over variable terrain and calculates propagation loss vs. height and range. Propagation loss is displayed in dB contours on a height vs. range plot. TPEM is based on the split-step Fourier PE method and was originally Developed from an early PE model called PEPC, written by Fred Tappert. Propagation loss over variable terrain is modeled by shifting the field an appropriate number of bin widths correspondc ing to the height of the ground. The field is determined using the smooth earth PE method.

The USB Multi-Interface driver is a replacement driver for the system provided Multi-Interface driver. This driver was Developed to overcome some bugs that are included in the build in driver and to introduce new features. The driver is compatible to the system provided Multi-Interface driver. If the driver is installed on a system, it does not automatically replace the system provided driver. It exists parallel to the system driver and is assigned to a device during the installation process.
To review what a metaball is, and how to render them and to describe a
new optimization I ve made for rendering metaballs. For complex scenes,
it can render hundreds of times faster, though I m certain others have
discovered this trick as well. It does very slightly change the
characteristic shape of the blobs, but there is no loss in image quality
whatsoever. (I actually Developed all this about two years ago, but just
now felt like writing it all down, and had the time!)
Last week I posted an article on a simple C++ template class, XYDataArray, I used in my system development tool. The main purpose of this template class is to store and sort general data types. I needed to implement the same thing in Java, since the tool I Developed has a compatible Java version. I checked the Java SDK documentation before writing my own code, and found that almost everything I needed is already there, like the C++ case.
