A New Kinematic Model and Control Strategy for a Mobile Platform for Transporting Lightweight Manipulators
This work is concerned with the mechanical design and the description of the different components of a new mobile base for a lightweight mobile manipulator. These kinds of mobile manipulators are normally composed of multiple lightweight links mounted on a ...
MDPI2018Axially equilibrated displacement-based beam element for simulating the cyclic inelastic behaviour of RC members
Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini
Distributed plasticity beam elements are commonly used to evaluate limit state demands for performance based analysis of reinforced concrete (RC) structures. Strain limits are often preferred to drift limits since they directly relate to damage and are the ...
Wiley-Blackwell2017Higher-order continuation method for the rigid-body kinematic design of compliant mechanisms
Simon Nessim Henein, Lennart Rubbert
Compliant mechanisms are of great interest in precision engineering. In this paper we propose a higher order continuation method to help their rigid-body kinematic design. The method helps to investigate the choice of a mechanism configuration through the ...
Elsevier2017Generating Calligraphic Trajectories with Model Predictive Control
We describe a methodology for the interactive definition of curves and motion paths using a stochastic formulation of optimal control. We demonstrate how the same optimization framework can be used in different ways to generate curves and traces that are g ...
2017Curvature-Controlled Defect Localization in Elastic Surface Crystals
Pedro Miguel Nunes Pereira de Almeida Reis
We investigate the influence of curvature and topology on crystalline dimpled patterns on the surface of generic elastic bilayers. Our numerical analysis predicts that the total number of defects created by adiabatic compression exhibits universal quadrati ...
American Physical Society2016Analysis of shear transfer actions in reinforced concrete members using refined measurement techniques
Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Cavagnis
Detailed investigations on the role of the shear transfer actions in members without transverse reinforcement have traditionally been limited due to the possibilities offered by conventional measurement techniques. The main difficulty of such conventional ...
fib, Fédération International du Béton, Lausanne2016Model-based variables for the kinematic assessment of upper-extremity impairments in post-stroke patients
Silvestro Micera, Elvira Pirondini
Background: Common scales for clinical evaluation of post-stroke upper-limb motor recovery are often complemented with kinematic parameters extracted from movement trajectories. However, there is no a general consensus on which parameters to use. Moreover, ...
Biomed Central Ltd2016Three-Parameter Kinematic Theory for Shear-Dominated Reinforced Concrete Walls
Katrin Beyer, Pia Hannewald, Boyan Iliev Mihaylov
This paper is aimed at addressing the need for physically accurate and computationally effective models for predicting the response of shear-dominated reinforced concrete walls. The presented theory is based on a three-degree-of-freedom kinematic model for ...
Asce-Amer Soc Civil Engineers2016A Novel 4-DOF Origami Grasper With an SMA-Actuation System for Minimally Invasive Surgery
Minimally invasive surgery (MIS) is one of the most challenging techniques for robot designers due to the limited size of access points, the high miniaturization level, and the dexterity needed for performing surgical tasks. Conversely, only a few microfab ...
Ieee-Inst Electrical Electronics Engineers Inc2016Observability analysis of 3D AUV trimming trajectories in the presence of ocean currents using range and depth measurements
António Pedro Rodrigues de Aguiar
We analyze the observability properties of the kinematic model of an autonomous underwater vehicle (AUV) moving in 3D, under the influence of ocean currents, using range and depth measurements. The results obtained shed light into the types of trajectories ...
