In a synchronous MAC [9], nodes in the same neighborhood are time-synchronized for simultaneous wake-up at the beginning of a common cycle and transmit their data.
However, nodes' simultaneous wake-up in synchronous protocols results in higher collisions, and it is more difficult to implement in UWSNs.
More recently, fully simultaneous coupled viscous inviscid solvers employing the double wake method have been applied to yacht sail systems [15], the unsteady case of pitching airfoils in stall conditions [16], and the quasi-3D (2D panel method with rotational effects from Coriolis and centrifugal forces) cases of, initially, rotating airfoils [17] and, later, full wind turbine rotors [18].
Wind tunnel experiments, with simultaneous multi-pressure measurements on cylinders with frontal, wake and bilateral splitter plates, have been undertaken for a range of Reynolds numbers from 6.90×104 to 8.28×105.
Third, the simultaneous recordings of LFPs and tissue O2 during sleep and waking show unequivocally that the largest dHPC tissue O2 signals were actually recorded during REM sleep, in the absence of any animal movement.
The transition from wake to sleep is thought to be accompanied by a simultaneous reduction in autonomic arousal (Trinder et al., 2001) and high CVCwake may accelerate autonomic regulation toward this transition.
The simultaneous deaths of those three unarmed black males were responsible for waking up Americans who were accustomed to hearing and reading news reports before breezily moving on to the sports pages.
By means of direct numerical simulation (DNS) of the fluid flow and simultaneous Lagrangian tracking of particles, the influence of hairpin vortices on solid particles released in the wake of the obstacle is analyzed.
Method We examined the relationship between sleep-wake activity, recorded actigraphically over 6 weeks, along with ambient light exposure and simultaneous circadian clock timing, by collecting weekly 48 h profiles of a urinary metabolite of melatonin in 20 out-patients with schizophrenia and 21 healthy control individuals matched for age, gender and being unemployed.
At 7 a.m., we woke up to the chimes of the bougainvillea bird sanctuary outside the glass doors and simultaneous New York Times iPhone alerts buzzing both sides of the bed.
