This report presents a software system which enables a person, to play against an artificially intelligent Draughts player, using a physical Draughts board. The software system that is presented uses machine vision techniques to monitor the physical state of a Draughts board, and implements reinforcement learning and classical game playing search techniques to enable the system to learn to play...

Scrabble is a commonly played word game in which players take turns forming words using a set of seven letter tiles and placing them onto a grid, following placement rules similar to a crossword puzzle. Various applications exist for helping players with forming words from their tiles, but few account for all of the possible positions on the board simply because manually entering the board stat...

A spectrogram is a visual representation of temporal variations in spectral magnitudes at various frequencies of a dynamic signal. The digital spectrographic analysis involves short-time Fourier analysis of the acquired signal, conversion of the spectral magnitudes to dB scale and display of these magnitudes as gray level shades as a function of time and frequency along x and y axes, respective...

Tele-operated rovers offer huge application potential in the areas of emergency support, surveillance and security, in particular if they are small and easy to transport. In this context, the MERLIN outdoor rovers have been designed for robust operations in harsh outdoor environments at a total mass below 20 kg. The MERLIN rover system design aspects are described, including the rover on-board ...

In this paper, the development and application of a universal audio-DSP (digital signal processor) board will be described. It is called freeDSP. Our goal was to provide an affordable real-time signal processing solution for researchers and the do-it-yourself community. Easy assembling and simple programmability were the main focus. A solution based on Analog Devices’ ADAU1701 DSP chip together...

In the manufacture of printed circuit boards, electronic components are attached to a blank board by one or more pick-and-place machines. Each machine has component magazines that house replaceable feeders. Since component requirements differ among board types, each change of feeders can improve processing time but indicates a machine setup. We develop an integer programming model for the joint...

This paper describes an intelligent system for monitoring photovoltaic plants, detecting thefts or malfunctions and optimizing energy production by algorithm to drive solar trackers. Sensing/processing board detects environmental parameters and calculates produced power/energy for monitoring efficiency while anti-theft system reveals any critical condition. Designed board controls biaxial track...
