Simulation of Oxygen Transfer Rates in Circular Aeration Tanks

Experiments were conducted to study the performance of circular and square tank surface aerators on the oxygen transfer coefficient and to a limited extent on power requirements. All the tanks are geometrically similar except for their shapes. They consist of a rotor of diameter, D, fixed with six flat blades rotating with a speed, N, in pure waters of viscosity, υ, at room temperature. A simul...

Autonomous Recharging of Mobile Robots

The paper discusses technical issues related to autonomous recharging of mobile robots. In doing so, the paper focuses on robots with small to medium energy-consumption, i.e., robots powered by NiCd or NiMH-cells. A concrete set-up with autonomous robotic vehicles and their charging mechanism is presented. Several potential methods for controlling the actual charging are discussed. Pitfalls in ...

Oxygen Gas Phase Abundance Revisited

We present new measurements of the interstellar gas-phase oxygen abundance along the sight lines towards 19 early-type galactic stars at an average distance of 2.6 kpc. We derive O I column densities from HST/STIS observations of the weak 1355 Å intersystem transition. We derive total hydrogen column densities [N(H I)+2N(H2)] using HST/STIS observations of Lyman-α and FUSE observations of molec...
