V-Shaped Action Functional with Delay

Time Delay Control with Switching Action using Frequency-Shaped Integral Sliding Surface

Recently the Time Delay Control with Switching Action (TDCSA) method has been proposed as a promising technique in the robust control area, where the plant has unknown dynamics with parameter variations and substantial disturbances are present. When TDCSA is applied to nonlinear system having frequency resonances, TDCSA reveals chattering problem or undesired vibration. This undesired vibration...

Local and Global Friction Factor in a Channel with V-Shaped Bottom

This paper presents an experimental research on the distribution of local friction factor, fb, and global friction factor, f, over the cross-section of a channel with V-shaped bottom, which typically occurs in sewers and culverts. Several series of experiments were conducted for measuring velocity and boundary shear stress. It is found that, Darcy-Weisbach, f, is more sensitive than other resis...

Spatially Varied Flow Profiles in a V-Shaped Side-Channel

A Comprehensive Model for Stiffness Coefficients in V-Shaped Cantilevers

   During past decade the AFM based nanomanipulation has been focus of attention as the promising nano fabrication approach. The main challenge in this process is the real-time monitoring. Consequently, the dynamic models have been proposed as a solution to the existing challenge. In the modeling approach the magnitudes of the forces are proportional to the stiffness coefficients o...

Resistance to Flow in a V-Shaped Bottom Channel

Water flow in open channels is always subject to the resistance to flow and energy dissipation. For design purposes, one of the needed variables is the hydraulic resistance coefficient. For this mean, the influence of cross-sectional shape together with secondary flow cells and lateral distribution of true boundary shear stress have not yet been fully explored. This paper surveys the number of ...
