Resonant frequency and phase noise of nanoelectromechanical oscillators based on two-dimensional crystal resonators
(Elsevier, 2014)
This study presents a theoretical analysis of one of the most promising nanoelectromechanical (NEMS) components - A NEMS oscillator. The analyzed oscillator contains a stretched circular plate, fabricated of two-dimensional ...
Exploiting the Nonlinear Frequency Response Method to Evaluate the Potential of Forced Periodic Operation of Reactors
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2016)
Forced periodic operation of chemical reactors possess significant potential to improve numerous performance criteria. The corresponding analysis of reaction systems and the estimation of the magnitude of possible performance ...
Periodically operated CSTRs with simultaneous modulation of feed concentration and flow-rate- Nonlinear frequency response approach
(10th European Congress of Chemical Engineering (ECCE 10), Nice, France, 2015)
Possible improvements of chemical reactor performance through periodic modulation of one or more inputs have been investigated for several decades. In our previous investigations we have introduced the nonlinear frequency ...
Evaluation of possible performance improvement through periodic operation for the reaction of acetic acid anhydride hydrolisis
(European Symposium on Chemical Reaction Engineering (ESCRE 2015), Munich, Germany, 2015)
The nonlinear frequency response (NFR) method is a relatively new, fast and easy, analytical method for evaluating the performance of forced periodically operated chemical reactors. The method has been introduced in our ...
