The game of Scrabble is played with tiles. A tile either has a single letter written on it, or it is blank. In the latter case, the tile may be used to represent a letter of your choice. On your turn, you arrange the tiles to form a word. Each tile may be used at most once, but not ...
A technical trading system comprises a set of trading rules that can be used to generate trading signals. In general, a simple trading system has one or two parameters that determine the timing of trading signals. Each rule contained in a trading system is the results of parameterizations.

This demonstration models a flight control for the longitudinal motion of a Grumman Aerospace F-14 Tomcat. First order linear
approximations of the aircraft and actuator behavior are connected to an analog flight control design that uses the pilot s
stick pitch command as the set point for the air ...

The DSKs or eZdspTM LF2407 and the DMC1500 make up a table top motor
development system which allows engineers and software developers to evaluate
certain characteristics of the TMS320F240, TMS320F243, and TMS320LF2407 DSPs
to determine if the processor meets the designers application requirements. ...
c pgm to find redundant paths in a graph.Many fault-tolerant network algorithms rely on an underlying assumption that there are possibly distinct network paths between a source-destination pair. Given a directed graph as input, write a program that uses depth-first search to determine all such paths ...
The purpose of this study is to explore the possibilities offered by current Artificial Neural Net(ANN) structures and topologies and determine their strengths and weaknesses.
P3.20. Consider an analog signal xa (t) = sin (2πt), 0 ≤t≤ 1. It is sampled at Ts = 0.01, 0.05,
and 0.1 sec intervals to obtain x(n).
b) Reconstruct the analog signal ya (t) from the samples x(n) using the sinc interpolation
(use ∆ t = 0.001) and determine the frequency in ya (t) from your ...
