But there's also another lesson in the cash-for-clunkers experience: such rebates are a spectacularly inefficient way to implement environmental policy.
Without standardization, reviews would likely be sporadic, inefficient, and challenging to implement and subsequently inform future practice.
Or, even if the original reference variables are viewed favorably, the bureaucracy may have been inefficient and fail to implement schemes that are successful.
Moreover, distributed and decentralized control architectures are necessary as power systems are distributed large-scale networks with a lot of complexity, which makes centralized control expensive, inefficient and hard to implement.
(2) Virtualization techniques are often too complex and inefficient to be implemented on resource-constrained embedded devices.
To cover the whole multicast group, the use of retransmission has been discussed and proposed in [4 6]; however, those schemes are either inefficient or too complex to implement.
GPR is robust and easy to implement but becomes inefficient for large training sets compared to NN and MARS.
For example, a qualitative and in depth analysis of the most efficient and inefficient schools could provide additional useful information about how to implement efficient practices and avoid the inefficient ones.
Existing street lighting systems, in most of South Italy cities, are often inefficient due to the obsolescence of lamps and luminaires and of ineffective light control systems unable to implement efficient on-off and dimming strategies.
