One of our most vital resources nowadays is fresh water. Water quality refers to the condition of the water, including chemical, biological and physical characteristics with respect to its suitability for a particular purpose. The main purpose of this publication is to set up a virtual system for water analysis in order to measure particular parameters of the water before and after physicochemical...
This paper presents a LabVIEW based system of acquisition, processing and analysis of ECG (electrocardiogram) signals. Biomedical signal acquisition has made great advances in recent years due to the introduction of modern hardware and software technologies. Computer based signal processing systems are becoming an efficient approach for acquisition and analyzing of such signals. In our implementation...
The water quality analysis is important for human health and environmental protection. There are many physical and chemical methods for such analysis, with different accuracies, complexity and time consumption. In the presented paper, a colorimetric method, based on virtual instrumentation is suggested and considered in details. At the end of the paper, the concentration of free chlorine in water...
