This work demonstrates a novel multi-configurable three-state electrothermally-actuated microgripper. The state of the gripper refers to the electrical configuration of the hot and cold arms as well as the mechanical mode of operation. The gripper has three basic electrical configurations and...

This paper focuses on the problematic position tracking of a quadcopter under external disturbances by developing a super-twisting sliding mode controller (STSMC) based on a higher-order sliding mode observer (HOSMO). A generalized quadcopter model is presented with position and attitude...

The objective of this paper is to assess changes in braid radius and braid angle of braided composite tubes under tensile loading using stereomicroscope digital image correlation (DIC) based optical measurement techniques. Using this approach, displacement fields were calculated and three...

Ring vibration analysis is more challenging than straight beams analysis. In straight beams, the structural deformations depend on rotational and translational displacements; however, in rings, in addition to these, they also depend on the coupled tangential displacement caused by the curvature...

This paper proposes a cooperative adaptive cruise control model, adding a communication network structure to an existing model that has been shown to capture real commercial adaptive cruise control vehicle behavior. The proposed model is interesting because it only requires minimal information...
