The present invention provides a hybrid central / distributed and tiered video on demand (VOD) service network with tiered content structure. In particular, the present invention uses media servers located in both the headend station and the hub stations. Set-top boxes generally would be supplied VOD services from the high-demand content media servers located in the hub station nearest to the user. The central media server located in the headend would be used as an installed backup to the hub media servers; as the primary source for lower demand VOD services and as the source of the real time, centrally encoded programs with PVR (personal video recorder) capabilities.By distributing the servers to the hub stations, the size of the fiber transport network associated with delivering VOD services from the central headend media server is reduced. The invention provides that each user has access to several server ports located on at least two servers. Multiple paths and channels are available for content distribution to each user, assuring high system reliability and enhanced asset availability. Substantial cost benefits are derived from the reduced need for a large content distribution network and the reduced storage capacity requirements for hub servers.

A cost-benefit metric for load balancing virtual machines is used to estimate a net gain in resource availability achieved by a proposed virtual machine migration.

A method and apparatus for calibrating a reference oscillator and use of a calibrated reference oscillator is disclosed. To gain cost reduction advantages, a less accurate reference oscillator is utilized in a wireless communication device. The cost benefit is gained at the expense of reference oscillator accuracy in that its inability to generate a signal with a highly accurate reference frequency inhibits acquisition of a carrier or pilot signal. To compensate, a correction factor is generated by minimizing the difference between the reference oscillator signal and a signal of known frequency, such as an external reference signal. Access to the reference oscillator signal, or a signal related thereto, may be gained via the communication device antenna or a test port. The correction factor may be stored in the wireless communication device for use in conjunction with the reference oscillator to thereby generate the highly accurate reference signal at the reference frequency.

Methods and apparatus for pollution control which are well suited for use in a coal power plant are described. Ash is collected and injected into the flue gas stream at a location upstream of a cooling module. The ash acts as an absorbent and / or reactant material onto which condensate may condense.

A proactive adaptive radio methodology for the opportunistic allocation of radio spectrum is described. The methods can be used to allocate radio spectrum resources by employing machine learning to learn models, via accruing data over time, that have the ability to predict the context-sensitive durations of the availability of channels. The predictive models are combined with decision-theoretic cost-benefit analyses to minimize disruptions of service or quality that can be associated with reactive allocation policies. Rather than reacting to losses of channel, the proactive policies seek switches in advance of the loss of a channel. Beyond determining durations of availability for one or more frequency bands statistical machine learning also be employed to generate price predictions in order to facilitate a sale or rental of the available frequencies, and these predictions can be employed in the switching analyses The methods can be employed in non-cooperating distributed models of allocation, in centralized allocation approaches, and in hybrid spectrum allocation scenarios.
