This paper is about different techniques for intelligent processing of data obtained with water quality monitoring distributed systems. The techniques include a set of fuzzy neural networks (FuNNs) for modelling measuring channels and Kohonen Self Organizing Maps (K-SOMs) for information classification. Elements of FuNN and K-SOM optimization in terms of architecture and training are presented ...

In this work, we are modelling the physic-chemical parameters of water using bioindicator data (diatom taxa abundance data). Chemical status of the water (or water quality class) is defined by the values of measured physic-chemical parameters. Traditional approach to model these data is to learn a separate model for each parameter and then derive a global overview with some kind of summarizatio...
drinking water quality can be deteriorated by microbial and toxic chemicals during transport, storage and handling before using by the consumer. this study was conducted to evaluate the microbial and physicochemical quality of drinking water from bottled water coolers.a total of 64 water samples, over a 5-month period in 2012-2013, were collected from free standing bottled water coolers and wat...
The European Water Framework Directive (WFD) requires a holistic approach to water management, developing River Basin Management Plans to ensure good ecological status in water bodies. Modelling will form a vital component in defining ecological conditions and developing an appropriate programme of measures to attain good status. However, model credibility can be affected by various problems, i...
to know the water quality characteristics of tehran subterranean canals, from 20 feb. 1978 to 23 sept. 1978, samples were taken from 23 of them by simple random sampling without replacement, and were analyzed according to the 14th edition of standards method for the examination of water and waste water 1975. arithmetic average concentration of water analyses of 23 subterranean canals were drawn...
neurotoxicants present in water supply may affect human functions in terms of attention, response speed and perceptual motor speed. neurobehavioural performance can be influenced by gender, age and education levels. this study aims to assess the neurobehavioral performance of palm oil estate residents with private water supply in southern peninsular of malaysia.a total of 287 and 246 participan...
The long-term goals of this research are: (i) to identify all relevant physical processes that participate in and contribute significantly to sediment transport in nearshore coastal waters; (ii) to investigate each of the identified processes in order to understand the underlying physics in a quantitative manner; (iii) to develop simple predictive models for each process; and (iv) to incorporat...
Natural and man induced nutrient loads affect the functioning of freshwater ecosystems and restrict various water uses. In particular, internal pollution by nutrient remobilisation from sediment plays an important role in shallow water bodies. A sustainable management of such freshwater ecosystems can be achieved by using simulation models. To forecast the eutrophication process of a shallow ri...
Modelling of fish swimming patterns has long been a challenge for the aquaculture community. In this proposed work, the modeling of fish swimming patterns and water condition such as pH, temperature and dissolved oxygen in fish tanks are analysed using network cameras and water sensors. An enhanced object tracking algorithm consisting of a combination of motion detection and condensation algori...
