Abstract: Geopolymers are used for several applications due to their sustainability, low density, low cost, excellent thermal properties, and fire resistance. Geopolymer concrete (GC) may possess superior fire resistance compared ...

Abstract: The consumption of waste tire rubber in concrete has gained more attention from the point of view of enhanced engineering properties of the product, and also sustainability. Numerous attempts have been stated on the use ...

Abstract: A heavy payload attached to the wrist force/moment (F/M) sensor of a manipulator can cause the conventional impedance controller to fail in establishing the desired impedance due to the noncontact ...

Abstract: Periodic structures have interesting acoustic and vibration properties making them suitable for a wide variety of applications. In a periodic structure, the number of frequencies for each wavevector depends on the ...

Abstract: The unifying idea for most model-based control approaches for parallel mechanism is to derive a minimal-order dynamics model of the system and then design the corresponding controller. The problem ...

Abstract: The equality and inequality constraints on constraint force and/or the actuator force/torque arise in several robotic applications, for which different controllers have been specifically developed. ...

Abstract: A gauge-invariant formulation for deriving the dynamic equations of constrained multibody systems in terms of (reduced) quasivelocities is presented. This formulation does not require any weighting ...

Abstract: Suburban sprawl has caused many problems in the last several decades. Of particular concern is overreliance on the automobile and the lack of alternative forms of transportation such as walking, bicycling, and transit. The ...

Abstract: Closed-form direct and inverse kinematics of a new three-degree-of-freedom (DOF) parallel manipulator with inextensible limbs and base-mounted actuators are presented. The manipulator has higher ...

Abstract: The manipulator discussed in the paper titled “Kinematics of a New High-Precision Three-Degree-of-Freedom Parallel Manipulator” (1) is a three-degree-of-freedom simplification of a six-degree-of-freedom ...
