The flexible needle made of nickel titanium alloy has the characteristics of shape memory, biocompatibility, corrosion resistance and excellent elastic deformation ability, which meets the basic requirements of biomedical puncture needle. Therefore, in this paper, the material property of the puncture ...
Abstract An adaptive optimal control model for building cooling and heating sources is presented with the aim of achieving global optimization and satisfying the requirements of time and accuracy in HVAC system control. The adaptive optimal control model includes the optimal control model, parameter iden...
It also applies to many private jobs if they ever got any government financing or loans, through imposition of “prevailing wage” requirements (prevailing wage is essentially whatever the standard union pay rates are). In addition, states by Democrats impose such requirements very broadly, and in...
A survey revealed that the conventional methods stated above are cumbersome with respect to the integration of HVDC modeling in OPF and higher computational requirements [23]. Nevertheless, they do not guarantee optimum solutions for practical nonlinear, non-convex problems. Consequently, researchers ...
The minimum airflow rate for building load calculated by Equation (5) is 143 CFM (67 L/s) and its ratio calculated by Equation (6) is 35%. To meet the ventilation air requirements [7], we will give about 16 CFM (8 L/s) for fresh air. During winter, when the outside air ...
