  • Identification for process control and bioengineering: open loop frequency domain estimation

    A previous paper has outlined a novel method for estimation of the parameters (including the time delay) of a general Single Input, Single Output (SISO) process model from an appropriate number of arbitrarily specified points on the process frequency response. The method involved combining an analytical approach with a least squares approach using a gradient algorithm, to provide accurate ...

  • Top five reasons why monitoring the CO2 concentration is a great idea

    CO2 has been a very hot topic for a few years now mainly due to its relation to climate change and also government policy. Leaving this aside, controlling and monitoring indoor levels of carbon dioxide inside building is important for everyone to consider for safety, health and even energy efficiency. Here are 5 reasons why you should by all means measure the CO2 levels in your space. ...

  • Copper Electrowinning in the Absence of Acid Mist: Six Years of Industrial Application

    Acid Mist Capture - Abstract with details about this technology fully developed by SAME. This paper reviews the fundamentals of a state – of – the art tankhouse ventilation system where acid mist captured at the source is further treated through high efficiency scrubbers allowing the releasing of clean and dry air to the ambient. Results obtained at plants show that acid mist concentration ...

  • Reducing Downtime for a Consumer Electronics Manufacturer

    Matrix® AP Harmonic Filters provided the necessary solution for reducing harmonics to stablize operations and increase efficiency. Good quality power can make a significant difference for many manufacturing plants such as those that build consumer electronics. Variable Frequency Drives (VFDs) are often used to control the water and ventilation systems for these ...
