ABAQUS is a general purpose finite element analysis program which is widely used to analyses mechanical, structure and civil engineering problems. Abaqus has some special feature for analysing fracture mechanics problems, and therefore it is a main tools for the FE-analysis in the Fracture Group at ...

The module LSQ is for unconstrained linear least-squares fitting. It is based upon Applied Statistics algorithm AS 274 (see comments at the start of the module). A planar-rotation algorithm is used to update the QR- factorization. This makes it suitable for updating regressions as more data become a ...

he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a constant period. The current value of this signal at a certain poiTnt of time is proportional to its Duty Cycle. That s the High Time during one perio ...

Unzip this file into a writeable directory. You should end up with a "Geocode" project, as well as Bitmaps and TestData directories. This sample geocodes single-match zip codes, entered by the user, or a batch-match of a table of zips (and other info) against a point shapefile. The point data sh ...

uc/os-ii for 8051 This package provides the sources required to use the uC/OS-II v2.00 real time kernel on the 8051 processor. To use this package you will need the TASKING C Compiler toolset v6.0r1 or higher. For info on TASKING products you can contact our Web-site at: http://www.tasking.com U ...

Decoding most of the infrared signals can be easily handled by PIC16C5X microcontrollers. This application note describes how this decoding may be done. The only mandatory hardware for decoding IR signals is an infrared receiver. The use of two types is described here. Both are modular types used of ...
