The extraordinary growth of the World Wide Web has been fueled by the ability it gives authors to easily and cheaply distribute electronic documents to an international audience. As Web documents have become larger and more complex, however, Web content providers have begun to experience the limitations of a medium that does not provide the extensibility, structure, and data checking needed for large-scale commercial publishing. The ability of Java applets to embed powerful data manipulation capabilities in Web clients makes even clearer the limitations of current methods for the transmittal of document data.
this m file can Find a (near) optimal solution to the Traveling Salesman Problem (TSP) by setting up a Genetic Algorithm (GA) to search for the shortest path (least distance needed to travel to each city exactly once)
Notes:
1. Input error checking included
2. Inputs can be specified in any order, so long as the parameter pairs are specified as a parameter , value
There is an example of how to use the LDPC encode/decode with AWGN
channel model in files .\ldpc_decode.m and .\GFq\ldpc_decode.m.
There are a few parity check matrices available in the code but
you can use other matrices provided you have enough memory to load
them. I suggest checking out matrices in Alist format available on
David MacKay s web site.You will need to have access to a MEX compiler
to be able to use a few functions written in C.

In this paper, we describe the development of a mobile butterfly-watching learning (BWL)
system to realize outdoor independent learning for mobile learners. The mobile butterfly-watching
learning system was designed in a wireless mobile ad-hoc learning environment. This is first result
to provide a cognitive tool with supporting the independent learning by applying PDA with
wireless communication technology to extend learning outside of the classroom. Independent
learning consists of self-selection, self-determination, self-modification, and self-checking.
Scotia Airlines is a new budget airline operating between Glasgow Airport and the Western
Isles. It operates two 24-seater light passenger aircraft and requires a flight booking system.
Because Scotia offers low cost air travel, there is a need to treat each flight as single cost centre
and to be able to ascertain, at any moment, the amount of the cash taken for that flight.
Reservations and bookings cannot be made until the flight details have been finalised (flight
number, departure and arrival airports). A seat on a flight is considered booked when payment
as been received for it. When a reservation is confirmed (changed to booked), the passenger
name is checked against the original reservation.
A flight can be in any of the following states:
Available for bookings
checking in
Boarding
Closed
The jacobi.f program solves the Helmholtz equation on a regular mesh, using an iterative Jacobi method with over-relaxation. Parallelism is exploited in both the solver and the numerical error checking
Programs in the irregular grid design package described in this manual are used to carry out five main functions:
verification and adjustment of coastline and bathymetric data
preparation of an irregular triangular depth grid covering the domain to be modelled
production of a preliminary irregular triangular model grid with nodes suitably positioned for accurate and efficient numerical modelling
interactive checking and editing, including trimming and joining, of model grid
display and plotting of model output.
This is GPS Matlab findPreambles finds the first preamble occurrence in the bit stream of
each channel. The preamble is verified by check of the spacing between
preambles [6sec] and parity checking of the first two words in a
subframe. At the same time function returns list of channels, that are in
tracking state and with valid preambles in the nav data stream.
Very simple USB 1.1 PHY. Includes all the goodies: serial/parallel
conversion, bit stuffing/unstuffing, NRZI encoding decoding. Uses a
simplified UTMI interface. Currently doesn t do any error checking in
the RX section [should probably check for bit unstuffing errors].
Otherwise complete and fully functional.
There is currently no test bench available. This core is very simple
and is proven in hardware. I see no point of writing a test bench at
this time.
