Centralized Path Planning for Multi-aircraft in the Presence of Static and Moving Obstacles
This article proposes a new approach for centralized path planning of multiple aircraft in presence of the obstacle-laden environment under low flying rules. The problem considers as a unified nonlinear constraint optimization problem. The minimum time and control investigate as the cost functions and the maximum velocity and power consider as the constraints. The pseudospectral method applies ...
متن کاملFIXED-BED ADSORPTION OF CONGO RED ONTO TEA WASTE IN THE PRESENCE OF Fe2O3 NANOPARTICLES: AN EXPERIMENTAL AND MODELING STUDY
In this study, tea waste (TW) is employed for the removal of Congo red (CR) from aqueous solutions in a fixed-bed column at 30 °C. The breakthrough curves of the adsorption process of CR on TW at three different flow rates are determined. The results revealed that the breakthrough curves were dependent on flow rates in a manner in which a lower flow rate was in favor of the CR adsorption in the...
متن کاملBrownian dynamics of concentrated polymers in two dimensions
Two-dimensional simulations of the Brownian dynamics of polymers in a grid of topological obstacles were carried out in this study. A first model made use of the exact expression for the free energy of a chain with fixed ends interacting with an obstacle and can be used to derive the elastic force acting on the subchains of a Rouse-like model. With this model we calculated the diffusion coeffic...
متن کاملDestruction of Amylopectin in the Presence and Absence of TiO2 Nanoparticles
Today, the use of natural polymers and their replacement with synthetic polymers in various fields of science has attracted much attention. Reducing the associated risks, easy access, and being cost-effective are among the advantages of using natural polymers compared to the synthetic polymers. In this research, the destruction of amylopectin in the presence and absence of titanium dioxide nano...
متن کاملIon Imprinted Affinity Cryogels for the Selective Adsorption Uranium in Real Samples
In this research, selective adsorption of U(VI) in aqueous solutionsin the presence of various lanthanide ions by using U(VI)-imprinted cryogel polymer was conducted. For this purpose, the prepared pHEMA-(MAH)3-U(VI) cryogel polymer by free radical polymerization method. U(VI) was desorbed with 5.0 mol/L HNO3 and thus U(VI)-imprinted were created onto p-HEMA-(...
