A Novel Family of Parallel Mechanisms With Synchronous Telescopic Parallelograms
IEEE Access, 2019 A novel synchronous telescopic parallelogram mechanism with movement realized by a belt drive is proposed, from which a compound kinematic limb is derived. According to the configuration derivation, a class of two-translation (2T), three-translation (3T)

Dislocations in uniaxial lamellar phases of liquid crystals, polymers and amphiphilic systems
, 1995 Dislocations in soft condensed matter systems such as lamellar systems of polymers, liquid crystals and ternary mixtures of oil, water and surfactant (amphiphilic systems) are described in the framework of continuum elastic theory.

A Computational Approach for Constructing the Reachable Workspaces for Redundant Manipulators [PDF]
, 2003 An efficient computation of 3D workspaces for redundant manipulators is based on a “hybrid” algorithm between direct kinematics and screw theory.

A Robotic Mechanism to Validate the Origin of Avian Flight
IEEE Access, 2018 A fundamental way to quantify the origin of flight is the implementation of experiments on the running bipedal with/without flapping wings in order to capture the kinematics of a bird quantitatively. To this purpose, the measured parameters should be the

On Dislocations in a Special Class of Generalized Elasticity
, 2005 In this paper we consider and compare special classes of static theories of gradient elasticity, nonlocal elasticity, gradient micropolar elasticity and nonlocal micropolar elasticity with only one gradient coefficient.

International Journal of Advanced Robotic Systems, 2018 The traditional Denavit–Hatenberg method is a relatively mature method for modeling the kinematics of robots. However, it has an obvious drawback, in that the parameters of the Denavit–Hatenberg model are discontinuous, resulting in singularity when the ...

Solution of an inverse kinematics problem using dual quaternions
International Journal of Applied Mathematics and Computer Science, 2020 The paper proposes a solution to an inverse kinematics problem based on dual quaternions algebra. The method, relying on screw theory, requires less calculation effort compared with commonly used approaches.

Defects in Chiral Columnar Phases: Tilt Grain Boundaries and Iterated Moire Maps
, 1995 Biomolecules are often very long with a definite chirality. DNA, xanthan and poly-gamma-benzyl-glutamate (PBLG) can all form columnar crystalline phases. The chirality, however, competes with the tendency for crystalline order. For chiral polymers, there
