The primary objective of most existing scheduling mechanisms is to improve QoS at single grid layer, while the QoS optimization at multiple grid layers is seldom considered.
However, most of existing mechanisms focus on auction-based allocation of cloud resources rather than on the approaches to performing tasks by the allocated cloud resources.
To be effective, we also need to recognize that most existing conflict prevention mechanisms developed over the years assume conflict between states, while most conflict today is within states, and to make appropriate adjustments.
In fact, most existing climate-related financing mechanisms are designed to mimic the effect that a price for carbon would have, and thereby reflect the true social, economic, and environmental costs of GHG emissions.
Second, most existing applications do not provide mechanisms to accommodate variability in prior class frequencies.
Our work deviates from the current research in that most existing papers usually assume the mechanism in which primary users lease their spectrum to secondary users for a fraction of time and in exchange, they get cooperative transmissions or other benefits.
Most existing research on parallel cable-driven mechanisms has been performed while neglecting cable mass.
It is not just that these problems are scientifically difficult, it is that existing mechanisms for supporting research and most existing research organizations do not provide an effective framework for a concerted effort to tackle these problems.
The chronic progressive nature of dopaminergic neurodegeneration, which is absent in most existing PD models, makes this new model invaluable for the study of mechanisms of PD progression.
By contrast with anaemia, arthritis and cancer, evidence about the underlying mechanisms in asthma is much less well-established, with most existing evidence coming from patients with long-standing and clinically severe asthma; further research in broader populations is needed.
