We investigated the effects of orientation angle on the adhesion of single gecko setae using dual-axis microelectromechanical systems force sensors to simultaneously detect normal and shear force components. Adhesion was highly sensitive to the pitch angle between the substrate and the seta's stalk. Maximum lateral adhesive force was observed with the stalk parallel to the substrate, and adhesi...

The aim of this research is to compensate the multivariable system’s Tele-control performance and preserve the stability of closed-loop system. Generally, in Tele-control systems, it contains two time-delay elements that have influence on design of the input signals and processing of output signals. Therefore, the closed-loop performance of the system is unstable and tracking characteristic of ...

In this paper, three dimensional flow characteristic was presented by a revision of an impeller of an axial turbo fan for improving the airflow rate and the static pressure. TO consider an incompressible steady three-dimensional flow, the RANS equations are used as the governing equations, and the standard k-ε turbulence model is chosen. The pitch angles of 44°, 54°, 59°, and 64° are implemente...

The article presents the results of research on operation a wind microturbine model with an adjustable blade pitch angle. physical basics turbine and methods its optimal control are discussed. measurements carried out for selected geometry possibility adjusting angle presented. tests were resistive load linear characteristic non-linear Li-Po battery. simple MPPT algorithm practical controlling ...

A position control system utilizing pitch feedback is being developed. The system will be demonstrated on a robot playing a musical instrument called the theremin. Unlike previous research involving computationally intensive pitch sensors, we would like to explore the possibility of a control system using a pitch sensor with a low computation overhead. The robot is being improved upon to make i...

Abstract The motional Stark effect (MSE) diagnostic has been a standard measurement for the magnetic field line pitch angle in tokamaks that are equipped with neutral beams. However, MSE data not always available due to experimental constraints, especially future devices without Here we develop deep-learning based model (SGTC-QR) can reconstruct safety factor profile mimic traditional equilibri...

Plate heat exchangers are widely used in industries due to their special characteristics, such as high thermal efficiency, small size, light weight, easy installation, maintenance, and cleaning. The purpose of this study is to consider the effect of depth, angle, and pitch of hemispheric Chevrons on the convective heat transfer coefficient and pressure drop. In the simulation of the heat ex...
