Integrated optimization of nonlinear R/C frames with reliability constraints [PDF]

open access: yes, 1989
A structural optimization algorithm was researched including global displacements as decision variables. The algorithm was applied to planar reinforced concrete frames with nonlinear material behavior submitted to static loading. The flexural performance

Estimation of elastic and viscous properties of the left ventricle based on annulus plane harmonic behavior [PDF]

open access: yes, 2006
Assessment of left ventricular (LV) function with an emphasis on contractility has been a challenge in cardiac mechanics during the recent decades. The LV function is usually described by the LV pressurevolume (P-V) diagram. The standard P-V diagrams

Design and Validation of an Improved Rotational Variable Stiffness Mechanism

open access: yesMachines
In various aspects of robotics, including human–robot interaction, the ability to dynamically adjust the apparent stiffness of an interaction (e.g., between the robot and its environment or between the robot and its payload) has become an important ...

A novel model for one-dimensional morphoelasticity. Part II - Application to the contraction of fibroblast-populated collagen lattices [PDF]

open access: yes, 2011
Fibroblast-populated collagen lattices are commonly used in experiments to study the interplay between fibroblasts and their pliable environment. Depending on the method by which\ud they are set, these lattices can contract significantly, in some cases ...

Deconfined quantum criticality in the two dimensional Kondo lattice model [PDF]

open access: yes, 2005
We investigate the continuous quantum phase transition from an antiferromagnetic metal to a heavy fermion liquid based on the Kondo lattice model in two dimensions.

A Novel Laminar Jamming Mechanism for Variable-Stiffness Robotic Arms

open access: yesActuators
A central problem in human–robot interaction is the risk of severe injury in humans in the event of a collision with a rigid robot arm. The introduction of variable stiffness into a robot arm mitigates the effects of impact and generates a safe ...

Targetting Chaos through Adaptive Control

open access: yes, 1998
We describe adaptive control algorithms whereby a chaotic dynamical system can be steered to a target state with desired characteristics. A specific implementation considered has the objective of directing the system to a state which is more chaotic or ...
