The present invention takes into consideration the user-defined transfer requirements, the data characteristics, and the characteristics of the entirety of the network, including both the access links and the backbone and processing and storage resources in the backbone. The present invention the enables users to more optimally transfer data within the limitations of the existing network capabilities, negating requirements to update local or remote network facilities.
摘要:
The amount of N.sub.2 O emission from a fluidized bed reactor is reduced by adding a hydrogen radical providing additive (e.g. a hydrogen containing fuel such as natural gas or alcohol) to the flue gases discharged from the fluidized bed. Sufficient exygen is present in the flue gases--either by addition with the additive, or by addition of an excess to the combustion chamber--so that the additive reacts with the oxygen, typically raising the temperature of the flue gases (e.g. from about 700.degree.-900.degree. C. to about 950.degree.-1100.degree. C.) so that N.sub.2 O production is reduced about 10-90%. The additive may be injected in or just prior to a cyclone for separating particles from the flue gases, in a gas discharge immediately after the cyclone (e.g. just downstream of a heat exchanger for cooling the flue gases and flattening the velocity profile of the flue gases), just prior to a superheater of a convection section, or in a combustion chamber just prior to a gas turbine.
摘要:
Methods, systems, and computer-readable media for providing collaborative quality of service (“QoS”) for service-oriented architectures are described. The application services in the service-oriented architecture implement a QoS application-programming interface (“API”) in addition to the traditional service API. The QoS API may include a QoS reporting interface for reporting values of QoS metrics of the application service, a QoS mechanism interface that exposes details of dependability mechanisms utilized by the application service, and/or a QoS negotiation interface that allows dynamic negotiation of what QoS properties the application service provides and how the QoS properties are provided. Service consumers may utilize the QoS API of the various application services in the service-oriented architecture to collect dependability information regarding the application services and make service provider selection decisions during discovery and dynamic binding.

摘要:
Method and apparatus for using biofuel or waste material or both for energy production. The biofuel or the waste material is gasified in a fluidized bed gasifier (10), preferably a circulating fluidized bed gasifier. The gas produced in the gasifier is introduced into a boiler (12) equipped with fossil fuel burners (28, 28'28"), typically burners for pulverized coal. The gas is introduced at a level above the burners. Ash from the boiler may be used to form the bed of the gasifier. For control of NO.sub.x, the gas is burned in the upper part of the boiler at a low temperature level of 800.degree.-1050.degree. C. (1472.degree.-1922.degree. F.), preferably 850.degree.-900.degree. C. (1562.degree.-1652.degree. F.), and with a small excess air content of about 5-10 percent. In a second embodiment, the raw gas may be cleaned of harmful or noxious components, and cooled if desired, between the gasifier and the boiler in an additional circulating fluidized bed reactor (152) having a bed of coal ash.
