A twice-as-smart ligand is a small molecule that experiences a structural switch upon interaction with its target (i.e., smart ligand) that concomitantly triggers its fluorescence (i.e., smart probe). Prototypes of twice-as-smart ligands were recently developed to track and label G-quadruplexes: these higher-order nucleic acid structures originate in the assembly of four guanine(G)-rich DNA or ...

In this paper, an intelligent controller to control a smart base-isolated masonry structure is proposed. The smart base isolation consists of rubber bearings and a magnetorheological damper. This semi-active scheme takes advantage of the low power requirement of magnetorheological devices to achieve structural control. The controller is capable of mapping the behaviour of the controlled structu...

The active vibration suppression of a flexible link manipulator using a smart structure (piezoelectric actuator) is investigated. For this purpose, a Finite Element (FE) model is developed for the modal and transient analysis of a cantilever beam and a flexible link manipulator. The novelty of this work is in the development of an accurate finite element model of a piezoelectric and beam/manipu...

Recent developments on the optimization and parameter estimation in hybrid active-passive composite sandwich structures are presented. For this purpose, a mixed layerwise finite element model has been formulated, by considering a higher order shear deformation theory to represent the displacement field in the viscoelastic core and a first order theory for the displacement fields of the adjacent...

It is possible to model smart structures with piezoelectric materials using the product ANSYS/Multiphysics. In this study, the integration of control actions into the ANSYS solution is realized. First, the procedure is tested on the active vibration control problem with a two-degrees of freedom system. The analytical results obtained by the Laplace transform method and by ANSYS are compared. Th...

Abstract—This paper presents a numerical solution, namely limit and shakedown analysis, to predict the safety state of smart structures made of heterogeneous materials under unknown cyclic loadings, for instance, the flexure hinge in the micro-positioning stage driven by piezoelectric actuator. In combination of homogenization theory and finite-element method (FEM), the safety evaluation proble...

Smart structures are highly inter-connected adaptive systems that are coordinated by cyber systems to optimize specific system objectives. In this paper we consider the challenges for securing metro-scale smart structures. We use a threat model that allows for untrusted behavior to capture realistic IoT scenarios, and discuss vulnerabilities, exploits and attack vectors. Resilience is defined i...

The overall goal is to reduce spacecraft weight. volume, and cost by online adaptive non-linear control of flexible structural components. The objective of this effort is to develop an adaptive Neural Network (NN) controller for the Ball C-Side 1m x 3m antenna with embedded actuators and the RAMS sensor system. A traditional optimal controller for the major modes is provided perturbations by th...
