Quantum Electronics for Atomic Physics offers a path in quantum electronics for researchers in atomic physics. The booklet covers the standard themes, reminiscent of Gaussian beams, cavities, lasers, nonlinear optics and modulation strategies, but additionally features a variety of components now not frequently present in a textbook on quantum electronics.

This is a consequence of the turbulent momentum interaction between the inside and outside air flows. This phenomenon was first reported by the Israeli group and confirmed by Oman, and it results in the major augmentation effect of the system, a phenomenon which had not been previously recognized, with the result that for many years ducted turbines were thought not to be capable of giving a satisfactory performance. It is also important that the effect is considered to be mainly due to the ideal flow pattern and not to viscous action, as the test program was conducted with small models and with low Reynolds numbers, hence extension of scale might show disappointing results if viscous effects were predominant.
Rolling friction coefficients from railroad freight car technology are used. The cross-track force is computed in terms of the aerodynamic force expressions, and thus varies with position. The maximum cross- 30 D. G. Shepherd track force is important for calculating structural stresses and the tipping moment. There is also cart drag, which is calculated with a drag coefficient equal to the aerodynamic equivalent flat plate area, taken as invariant with flow angle, and integrated around the circuit for varying angular position.
For some value of V Ä , the values ofD and WR are then determined. 8. Figure 42 shows very clearly that as VR increases so must WR9 and as it decreases, the rotor size, as D, must increase. The selected value of W€ affects the cost minimization curves for values of VR, as this determines the size of WR and D, which in turn affect the costs of the system. We may be known for a particular application, usually for small units, but for utility power it is likely that the maximum energy for the given site is required.
