  • Sensor data processing for emergency response

    A gap with current Emergency Response (ER) is the lack of real-time information on the status of an incident. Wireless sensor networks have shown great potential in addressing this gap. However, sensor data streams often contain 'noise', thus they are too difficult to be directly interpreted. In addition, sensor data are often meaningless unless it is associated with time and location ...

  • Predicting influent PO4 using a multivariate soft sensor. Proceedings ICA2017

    Abstract: A method for implementing a multivariate Partial Least Squares (PLS) soft sensor is discussed with a focus on sensor robustness. Practical aspects of implementation are examined including handling of missing or poor input data, sensor and data diagnostics, automated soft sensor calibration, and on-line sensor operation. Proof-of-concept examples are drawn using data from a simulated ...

  • A generic state model with neighbourhood support from wireless sensor networks for emergency event detection

    Wireless Sensor Networks (WSNs) typically consist of numerous sensor nodes deployed in an area, for the purpose of detecting the existence of 'interesting' patterns or events. Although various event detection (ED) approaches have been researched, most are limited to the specific ED scenarios. This paper proposes a generic state model with neighbourhood support (NS) from WSNs for emergency event ...

  • Fabrication of highly ordered nanohoneycomb (ZnO/Pt) arrays

    The double nanohoneycombs (ZnO/Pt) on glass and Si substrates were fabricated by the two–step process of nanosphere lithography (NSL). The working parameters of the fabrication processes on nanohoneycomb performances were analysed and the factors affecting the size of nanohoneycombs, such as controlling nanosphere size, lift–off nanosphere and the second NSL process, were elucidated. In the ...

  • Aware online interdependency modelling via evidence theory

    Critical infrastructure interdependency models are typically used in a simulation–based perspective, in order to perform 'what if?' analyses and identify structural vulnerabilities in a dynamic perspective. While in the literature some attempts have been made to use interdependency models at real time, such approaches are flawed by the inability to properly determine the ongoing situation. ...

  • A smart decision support systems based on a fast classifier and a semantic post reasoner

    In modern monitoring systems for critical infrastructures protection, there is the need to design automatic decision support systems with high reliability and real-time constraints. These features are usually in contrast as there is a significant trade-off between performance and precision. In this paper, we propose an innovative approach for smart event detection and enriched phenomena ...

  • Fault Detection for Control of Wastewater Treatment Plants

    Abstract: Interest in real-time model-based control is increasing as more and more facilities are being asked to meet stricter effluent requirements while at the same time minimizing costs. It has been identified that biological process models and automated process control technologies are being used at wastewater treatments plants throughout the world and that great potential for optimising ...

  • Probabilistic qualitative analysis for fault detection and identification of an on-line phosphate analyzer. Int. J. Adv. Eng. Sci. Appl. Math.

    Abstract: On-line, real-time collection of measurements remains a key challenge in water quality monitoring and control due to unknown and varying quality of on-line sensor data. Today’s data quality assessment is typically based on a comparison of sensor-based measurements and grab samples of the sampled solution taken next to the on-line analyzer and analyzed in a laboratory. In this ...

  • Environmental indicator assessment for smart growth

    Two of the major environmental indicators evaluated in this study are changes in fragmented forests and increase in impervious surfaces. Both of these indicators have important implications for adverse environmental impact in the county. Satellite imagery and airborne photography were used to collect information on ground characteristics for these two indicators. Change detection analysis of the ...

  • Senix ultrasonic sensors guide Oracle boat

    Oracle Team USA won the 2013 America’s Cup race with one of the most efficient sailing vessel ever built. Oracle Team USA’s AC72-class yacht, USA-17, was a 100’ long, 90’ wide and 223’ tall carbon fiber technological marvel capable of speeds in excess of 50 knots (57 mph). The yacht actually “flies” off the water on hydrofoils that lift the entire hull ...

  • Research on buried pipe corrosion assessment using corrosion sensors

    This research aims to establish a water pipeline replacement plan that employs soil-corrosion evaluation technology and utilizes easy-to-use corrosion sensors by assessing the performances and validating operation methods based on verification experiments. Since 2005, we have assessed the performances of two different types of sensor, and have confirmed that bar-type sensors can detect soil ...

  • Snow cover mapping using IRS-P6 AWiFS data and the relationships between some climatic factors with snowpack in the northwest of Iran

    In this study, we explored the potential of the multispectral and multi-temporal IRS Advanced Wide Field Sensor (AWiFS) data for mapping of the snow cover in the northwest regions of Iran. The AWiFS snow cover maps, based on the unsupervised classification method, were compared with the estimates of snow cover area derived from the moderate resolution imaging spectroradiometer (MODIS) images ...

  • Comparative investigation of Source Term Estimation algorithms using FUSION field trial 2007 data: linear regression analysis

    Given a warning based on detections at a few sensors, it should be useful to rapidly provide an estimate of the location, time of release and amount of material released. Such information could lead to refined predictions of the hazardous area and support follow–on actions to investigate the cause and nature of the hazardous release. In September 2007, a short–range test designed to ...

  • Basic tests for checking validity of field data

    The following guidelines are suggested for verifying micrometeorological data gathered in field experiments. It is assumed, for simplicity, that the observations being tested are made over open, relatively flat and uniform terrain, with small roughness elements. It is also assumed that the sensors and the data acquisition and recording hardware are basically sound and that the purpose of the ...

  • What is SDI-12

    SDI‑12 was originally developed in 1988 for microprocessor-based environmental sensors. In 1992, the SDI‑12 documentation was refined by NR Systems, under contract with the U.S. Geological Survey. The intention was to provide a common sensor interface for environmental data collection equipment. The SDI‑12 technical committee continues to maintain ...
