Traffic intersections throughout the United States combine fixed, semi-actuated, and fully actuated intersections. In case of semi-actuated intersections, uncertainties are considered in phase duration. These due to car waiting queues pedestrian crossing. Intelligent transportation systems deployed traffic infrastructure can communicate Signal Phase Timing messages (SPaT) vehicles approaching c...
In this paper, current-voltage characteristic of a resonant tunneling diode under electromagnetic radiation has been calculated and compared with the results when there is no electromagnetic radiation. For calculating current -voltage characteristic, it is required to calculate the transmission coefficient of electrons from the well and barrier structures of this device. For calculating the tr...
Upper limbs of human beings are extremely special and significant, which obtain crucial function to achieve manipulations intelligently and dexterously. Gesture-Changeable Under-Actuated (GCUA) grasping function is presented to improve the capability of robotic hands to achieve humanoid manipulations with low dependence on control and sensor feedback systems, which includes traditional under-ac...
Arterial stenosis is a high-risk disease accompanied by large amounts of calcified deposits and plaques that develop inside the vasculature. These should be reduced to improve blood flow. However, current methods used reduce require externally controlled actuation systems resulting in limited workspace or patient risks. This results an unexplored preference regarding revascularization strategy ...
Since the piezoelectrically actuated system has nonlinear and time-varying behavior, it is difficult to establish an accurate dynamic model for a model-based sensing and control design. Here, a model-free adaptive sliding controller is proposed to improve the small travel and hysteresis defects of piezoelectrically actuated systems. This sensing and control strategy employs the functional appro...
Actuated lidar, where a scanning lidar is combined with an actuation mechanism to scan a 3D volume rather than a single line, has been used heavily on a wide variety of field robotics applications. Common examples of actuated lidar include spinning/rolling and nodding/pitching configurations. Due to construction of actuated lidar, the center of rotation of the lidar mirror may not coincide with...
We analyze pull-in instability of electrostatically actuated microelectromechanical systems, and study changes in pull-in parameters due to the Casimir effect. When the size of the device is reduced, the magnitude of the Casimir force is comparable with that of the Coulomb force and it significantly alters pull-in parameters. We model the deformable conductor as an elastic membrane and consider...
Developing technology and industry and increasing application of electromagnetic fields in medicine, threaten the environment and human health. Biological effects of these fields depend on the field magnitude and physical characteristics of exposed tissue. In order to research the effects of electromagnetic fields on kidney tissue on electromagnetic field generator was made with intensities of ...
The term "electromagnetic fields" (EMF) is a combination of electric and magnetic fields as a diagnostic method as well as a therapeutic tool with many advantages such as ease of operation and painlessness, very controllable, which today has found wide application in regenerative medicine and also cancer treatment. In addition to organs such as nerves, hearts, and bones that have an electrica...
