      Liquid-crystalline phase behavior in a zwitterionic tetraazapentacene 

      Riley, A. E.; Mitchell, G. W.; Koutentis, Panayiotis Andreas; Bendikov, M.; Kaszynki, P.; Wudl, F.; Tolbert, S. H. (2003)
      A 5,7-dioctadecylquinoxalinophenazine zwitterion 1 has been investigated to determine its thermal phase behavior. A combination of differential scanning calorimetry (DSC), variable temperature low- and high-angle X-ray ...

      Resistive switching phenomena in Li xCoO 2 thin films 

      Moradpour, A.; Schneegans, O.; Franger, S.; Revcolevschi, A.; Salot, R.; Auban-Senzier, P.; Pasquier, C.; Svoukis, E.; Giapintzakis, John; Dragos, O.; Ciomaga, V.-C.; Chrétien, P. (2011)
      A substantial resistive switching of Li xCoO 2 mixed-conductor thin films is observed for the first time. The occurrence of possible bipolar switching in these oxide thin films is by current-voltage curves, investigated ...

      Robust adaptive control for a class of MIMO nonlinear systems with guaranteed error bounds 

      Xu, H.; Ioannou, Petros A. (2003)
      The design of stabilizing controllers for multiple-input-multiple-output (MIMO) nonlinear plants with unknown nonlinearities is a challenging problem. The high dimensionality coupled with the inability to identify the ...

      Stability margins in adaptive mixing control via a Lyapunov-based switching criterion 

      Baldi, S.; Ioannou, Petros A. (2012)
      In all classes of linear adaptive control that involve switching or not there is no guarantee that after the switching stops or the adaptation is switched off the resulting closed loop linear time invariant system is stable ...

      Stability Margins in Adaptive Mixing Control Via a Lyapunov-Based Switching Criterion 

      Baldi, S.; Ioannou, Petros A. (2016)
      This paper proposes a Lyapunov-based switching logic within the framework of adaptive mixing control (AMC), where a weighted combination of a family of candidate controllers can be inserted in the loop to regulate the ...

      A switching control strategy for the attenuation of blood glucose disturbances 

      Markakis, M. G.; Mitsis, Georgios D.; Papavassilopoulos, G. P.; Ioannou, Petros A.; Marmarelis, V. Z. (2011)
      In this computational study we consider a generalized minimal model structure for the intravenously infused insulin-blood glucose dynamics, which can represent a wide variety of diabetic patients, and augment this model ...

      A switching controller for multivariable LTI systems with known and unknown parameters 

      Fidan, B.; Kosmatopoulos, E. B.; Ioannou, Petros A. (2002)
      The design of adaptive controllers for multi-input multi-output (MIMO) linear time invariant (LTI) systems is challenging due to the high dimension and parameterization issues associated with MIMO systems. In this paper ...

      Universal bufferless packet switching 

      Busch, Costas; Magdon-Ismail, M.; Mavronicolas, Marios (2007)
      A packet-switching algorithm specifies the actions of the nodes in order to deliver packets in the network. A packet-switching algorithm is universal if it applies to any network topology and for any batch communication ...

      Upper and lower bounds on fsm switching activity 

      Athanasopoulou, E.; Hadjicostis, Christoforos N. (2003)
      This paper obtains upper and lower bounds for the switching activity on the state lines of a finite state machine (FSM) that is driven with typical input sequences. By exploiting the symmetries between the Hamming distances ...
