Sensing, Understanding, and Shaping Social Behavior [PDF]

open access: yesIEEE Transactions on Computational Social Systems, 2014
The ability to understand social systems through the aid of computational tools is central to the emerging field of computational social systems. Such understanding can answer epistemological questions on human behavior in a data-driven manner, and provide prescriptive guidelines for persuading humans to undertake certain actions in real-world social ...

Movability in the sense of n-shape

open access: yesTopology and its Applications, 2005
All spaces are assumed to be compact metric ones. The paper deals with movable compact metric spaces, \(n\)-shape, \(n\)-movable spaces, and spaces \textit{movable in the sense of \(n\)-shape}. The latter is defined like ordinary movability, after replacing ordinary homotopy by \(n\)-homotopy: Two mappings \(f, g: X \longrightarrow Y\) are said to be \(

Shape Sensing for an UAV Composite Half-Wing: Numerical Comparison between Modal Method and Ko’s Displacement Theory

open access: yesAerospace, 2022
Shape sensing is the reconstruction of the displacement field of a structure from some discrete surface strain measurements and is a key technology for structural health monitoring. The aim of this paper is to compare two approaches to shape sensing that

Shape Sensing of a Complex Aeronautical Structure with Inverse Finite Element Method

open access: yesSensors, 2021
The inverse Finite Element Method (iFEM) is receiving more attention for shape sensing due to its independence from the material properties and the external load. However, a proper definition of the model geometry with its boundary conditions is required,

Real-Time Shape Estimation for Concentric Tube Continuum Robots with a Single Force/Torque Sensor

open access: yesFrontiers in Robotics and AI, 2021
Shape-sensing in real-time is a key requirement for the development of advanced algorithms for concentric tube continuum robots when safe interaction with the environment is important e.g., for path planning, advanced control, and human-machine ...

Coarse and Fine Two-Stage Calibration Method for Enhancing the Accuracy of Inverse Finite Element Method

open access: yesSensors, 2023
The inverse finite element method (iFEM) is a novel method for reconstructing the full-field displacement of structures by discrete measurement strain. In practical engineering applications, the accuracy of iFEM is reduced due to the positional offset of
