Active Noise Attenuation Bw

A new method for globallw reducing the amount of unwanted Power radiated bv acoustic sourcesy bw means of active devices, is Proposed. After examining PreviouslY reported passive and active noise attenuating technioues, and finding them to be unsuitable for some applications, a new method is Proposed. The scheme involves Placin an attenuating source close to the noise sourcer driven in such a w...

Objective This pilot study examined the eff ectiveness and trainer skills of the fi rst lay trainers with migraine. Methods In a stepwise training program eight lay trainers with migraine participated in a behavioural management training (BT) aimed at the prevention of migraine attacks by proactive relaxation and trigger management. After successful reduction of their migraine attacks, three la...

The effect of convection on pulsational stability

A review on the current state of mode physics in classical pulsators is presented. Two, currently in use, time-dependent convection models are compared and their applications on mode stability are discussed with particular emphasis on the location of the Delta Scuti instability strip.
