  • How much data is enough data?

    Short answer: it depends on the application and how the data is going to be used.  However, in many ways it boils down to context… For instance, in relation to climate change, if we look at global mean air temperature, it would be very difficult to assess any level of change over time if we did not have a collection of data in a time-series. ...

  • Wireless Real-Time Soil Data from Stevens Hydra Probe Soil Sensors Used In Contaminated Soil Cleanup Operation

    Up until the early 1970s when The US Congress passed The Clean Water Act, industrial chemicals and petroleum products were routinely dumped onto the ground or poured down wells. In those days, few people understood groundwater hydrology, and disposing of chemical waste underground seemed like a safe and easy solution. Depending on the chemistry, underground pollution can linger for centuries, ...

  • 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 ...

  • Dynamic soft sensors for detecting factors affecting turbidity in drinking water

    Effective monitoring of water quality is critical for water safety. In particular, online monitoring based on modeling is useful in several applications such as process assessment, hazardous event detection or common fault diagnostics in the water processes. Soft sensors have lately established themselves as a good alternative for different tasks of process control such as the acquisition of ...

  • Response time testing of temperature sensors using loop current step response method

    The Loop Current Step Response (LCSR) method is used for in–situ response time testing of temperature sensors as installed in an industrial process. This paper presents the theoretical foundation of the LCSR (test theory, LCSR equation and test procedures) and the author's research to validate its use in nuclear power industry applications. The validity of the LCSR method depends on how ...
