On-Line Realtime Water Quality Monitoring And Control For Swimming Pools, Paul Duffy, Gerard Woods, Sean O'Hogain, James Walsh, C. Caplier Sep 2009

On-Line Realtime Water Quality Monitoring And Control For Swimming Pools, Paul Duffy, Gerard Woods, Sean O'Hogain, James Walsh, C. Caplier

Conference Papers

Effective swimming pool water quality monitoring and control systems are important to safeguard public health and for bather comfort. Most Irish swimming pool monitoring systems rely heavily on manual methods for sampling, testing and data recording of important parameters. Microbiological testing is infrequent and results can often take days. The goal of this research is to develop a water quality monitoring and control system with real time data logging, automatic data analysis, remote monitoring and control, microbiological sampling capabilities and online connectivity. National Instruments hardware and its software package LabView form the basis of the monitoring and control system. Several …


Systematic Analysis Of Unknown Integrated Circuits, Michael Brutscheck Jan 2009

Systematic Analysis Of Unknown Integrated Circuits, Michael Brutscheck

Doctoral

In recent years the efficient and structured analysis of unknown CMOS integrated circuits (ICs) has attracted a lot of interest. Over the last decade different and non-invasive strategies have been developed to analyse unknown ICS. However, invasive procedures must always lead to the destruction of the system under investigation. Non-invasive approaches published so far have the disadvantage that ICs are analysed using very complex and very time consuming algorithms. The focus of this thesis is to develop a non-invasive and efficient procedure to determine fully unclassified digital CMOS ICs solely by their input-output behaviour. In this research, automata theory was …
