  1. 1. Biosensors and Automation for Bioprocess Monitoring and Control

    Author : M A Kumar; Bioteknik; []
    Keywords : online monitoring; ELISA; immunosensor; flow injection; Biosensor; bioprocess; control; environmental;

    Abstract : Bioprocess monitoring and control is a complex task that needs rapid and reliable methods which are adaptable to continuous analysis. Process monitoring during fermentation is widely applicable in the field of pharmaceutical, food and beverages and wastewater treatment. READ MORE

  2. 2. Data mining and analysis for characterizing paper from online multisensor measurements

    Author : Marcus Ejnarsson; Chalmers University of Technology; []
    Keywords : Kernel Based Novelty Detection; Feature Extraction; Kernel CCA; Monitoring; Paper Web; Time-Series Representation; Newsprint;

    Abstract : The objective of this thesis is to develop a multi-resolution tool for screening paper formation variations, aiming to detect abnormalities in various frequency regions ranging from millimeters to several meters. The abnormalities detected in different frequency regions give an indication for the paper maker about specific disturbances in the paper production process. READ MORE

  4. 4. On measurement and monitoring of reactivity in subcritical reactor systems

    Author : Carl Berglöf; Janne Wallenius; Vasily Arzhanov; Massimo Salvatores; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; reactor; ADS; accelerator-driven systems; subcriticality determination; noise techniques; pulsed neutron source; reactivity monitoring; Nuclear physics; Kärnfysik;

    Abstract : Accelerator-driven systems have been proposed for incineration of transuranic elements from spent nuclear fuel. For safe operation of such facilities, a robust method for reactivity monitoring is required. Experience has shown that the performance of reactivity measurement methods in terms of accuracy and applicability is highly system dependent. READ MORE

  5. 5. Arbitrary Waveform Impedance Spectroscopy for Characterization and Diagnostics of High Voltage Insulation

    Author : Björn Sonerud; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; insulation testing; aging; monitoring; discrete Fourier transforms; Dielectric measurements; dielectric materials;

    Abstract : In high voltage engineering the dielectric response technique is a widely used tool both for characterization of insulation materials and for diagnostics of components such as transformers and cables. Currently available techniques are not capable of measuring on-line which would be advantageous; when characterizing a material and evaluating the effect of different voltage magnitudes, waveforms and temperatures it is desirable to be able to observe the continuous development of the dielectric properties.
