Adrian Thompson's Hardware Evolution Page.
Adrian Thompson does Research on Evolvable Hardware.
I'm mainly interested in the use of `soft' computing techniques, such as neural networks and genetic algorithms, in engineering design
The main focus of this has been evolutionary algorithms to design microelectronic circuits and, more recently, nano-electronics
Evolutionary Electronics is the use of evolutionary algorithms in the design of electronic systems
There are many potential applications for evolutionary algorithms in electronics, such as optimisation of parameter values or component placement & routing, test pattern generation, and even in the design process itself
The focus of my own work has been to ask 'What can evolutionary design do that conventional methods can't?' rather than trying to compete with conventional design or automate it

Announcement, with many useful and entertaining forum comments. [Slashdot]
While this may be true for application programs, which are designed for end users, other areas of computers should not be made 'simple' for end users
This server operating system was designed with a 'user-friendly' interface to make it easier for 'administrators' to configure and maintain the system
My amiga without true memory protection was always more stable than W95's so-called memory protection...) - CPUs with MMUs wre prohibitively expensive at design time of the original amiga
It has relatively little to do with Amiga OSes 0 to 3, other than the name, and the fact that some of the original amiga people are designing it 'in the spirit of the original amiga' - whatever that's supposed to mean
Erlang - An Open Source Language for Robust Distributed Applications
article by Dr Lawrie Brown.
Erlang &— An Open Source Language for Robust Distributed Applications School of Computer Science, Australian Defence Force Academy, Canberra, Australia Email: Abstract This paper introduces Erlang , a functional language designed to support robust, reliable, distributed, near real-time applications
In additional, because the primary design focus was on distributed soft real-time systems, the language includes an extremely effective distribution and concurency mechanisms
Also, because the original design focus was not on user interface issues, graphical interfaces may not be as efficient as in some other languages, though they certainly are available
It was designed specifically to meet the robust, fault tolerant, requirements of telecommunications applications (eg
The AXD 301 system is designed for nonstop operation, with duplicated hardware, and modular software, which can be upgraded to facilitate the introduction of new functionality without disturbing traffic

Dude, You Need a Mac A prime constraint in designing the Supercomputer was cost
Varadarajan said that you can't design a Supercomputer and wait that long for delivery
He didn't need to 'test drive' because the equipment satisfied all of his design requirments

Sam's Laser FAQ - HeNe Laser Power Supply Design
HeNe Laser Power Supply Design.
HeNe Laser Power Supply Design Sub-Table of Contents Back to
This chapter deals with the more practical aspects of HeNe laser power supply design including circuits for providing the HeNe tube operating voltage (AC line and inverter types), starters, regulators, and modulators
The designs are very straightforward and aside from the power transformer, all parts are inexpensive and readily available
Inverter based approaches are generally small, light weight, and efficient, but may require more sophistication in design and hard-to-obtain, expensive, or custom parts
Some more sophisticated commercial power supply designs provide a variety of 'soft start' and other features to maximize HeNe tube life
Either a parasitic voltage multiplier or pulse (trigger) type starting circuit can be used with these designs
Even this may be excessive depending on its design margins
However, for a typical design, the total energy in this pulse is not very large even at the upper limit of the power supply
See the section: for a sample design using an oil burner ignition transformer
:-) These would likely result in designs that were impractical, excessively expensive, or extremely dangerous
