A novel machine health monitoring system
56,50 € *
ggf. zzgl. Versand

The health monitoring of a machine is an assessment wherein the significant change in performance parameters is observed and analyzed with an intention to predict the failure. In this context, many types of analyzers are available but the overall cost is very high and may not be affordable to all. Hence this research work presents a low-cost solution for the development of a novel machine health monitoring system that is reliable, accurate and easy to handle. An open-source platform Arduino Mega 2560 along with the ADXL335 accelerometer is integrated with MATLAB to store & display the acquired data. The program is designed to convert time domain response to frequency domain response using classic Fast Fourier Transform. The system exhibits time domain and frequency domain response to interpret the state of a machine component. The experimental assessment of the developed system with respect to the standard commercially available analyzer is carried out and showed equivalent competency. This system can be used as a monitoring tool in small scaleindustries & for laboratory work in engineering colleges.

Yakumo: A Physics-based Game with Physical Input
59,00 € *
ggf. zzgl. Versand

Yakumo is an exploration of the different technologies used in making a modern game, including graphics, physics simulation, 3D audio and content creation pipeline design. This book follows the processes involved in implementing a game which integrates all of these components, based on using OGRE 3D for graphics and Havok Physics for real-time physics simulation. This book also tackles common issues with such software, such as creating a camera that does not clip through surfaces, writing multithreaded code, and supporting reliable network communication. Implementation of an I/O library for iPhone OS devices is also described. This allows physical input to the game by taking advantage of the many sensors of the iPhone/iPod touch, including accelerometer and touch-screen input. In 2009 this book won the IBM Open Source Competition award (University of Limerick, Ireland). All technology produced during this project is released as open source software under the Apache License, Version 2.0 and is available online at http://daniel.ie/
