RIS-Based Code Index Modulation for Joint Active/Passive Transmission
IEEE Transactions on Vehicular TechnologyIn this paper, we employ a reconfigurable intelligent surface (RIS) to spread incident signals and develop RIS-based code index modulation (CIM) for joint active/passive transmission (JAPT).

Including the effect of solar radiation in dynamic indoor thermal comfort indices
, 2021The use of solar gains is one of the most effective passive strategies to reduce the heating energy demand of buildings. However, solar radiation not only affects the thermal balance of the building, but also that of the occupants.

Asymptotic stabilization of nonlinear systems using passivity indices
2016 American Control Conference (ACC), 2016This work presents a new controller design technique for asymptotic stabilization of nonlinear systems using passivity indices. The aforementioned indices measure the level of passivity of a system and we address the question of how to use this information to design a dynamic output feedback controller that stabilizes the closed-loop at a given ...

Feedback control of nonlinear systems using passivity indices
2015 IEEE Conference on Control Applications (CCA), 2015This paper presents a new controller design framework for nonlinear feedback systems using passivity indices. These indices measure the level of passivity of a system and can be used to set lower bounds to the parameters of a stabilizing controller.

Indicators of Active and Passive Coping in Myocardial Infarction Victims
Journal of Gerontology, 1992This retrospective study attempted to explore life events, personality factors, subjective perceptions, and coping reactions in myocardial infarction (MI) patients. Seventy-seven MI survivors participated in the study. The PERI Life Events Scale, the 16 PF personality inventory, and a questionnaire covering self-ratings of subjective perception and ...

Passivity indices and passivation of systems with application to systems with input/output delay
53rd IEEE Conference on Decision and Control, 2014A passivation method to passivate a given system by using an input-output transformation matrix is introduced. This matrix generalizes the commonly used methods of series, feedback and feedforward interconnections to passivate a system. Through an appropriate design of this matrix, positive passivity levels can be guaranteed for the system.
