    摘要： A method for measuring system response sensitivity, using live traffic and an analysis that converts randomly arriving stimuli and reactions to the stimuli to mean measures over chosen intervals, thereby creating periodically occurring samples that are processed. The system is perturbed in a chosen location of the system in a manner that is periodic with frequency p, and the system's response to arriving stimuli is measured at frequency p. The perturbation, illustratively, is with a square wave pattern.

    摘要： Method and apparatus for gasifying carbonaceous material, in which (a) product gas and ash, residual carbon a gasified tar compounds entrained therewith are discharged from a gasifying reactor to a product gas channel and cooled in a gas cooler, whereby tar compounds condense in a liquid state and tend to stick on heat surfaces; (b) solids containing ash particles and residual carbon separated from the gasification system, preferably from its product gas, are supplied to an ash reactor, in which the residual carbon reacts with oxygen and ash particles and exhaust gas is generated; and (c) ash particles are supplied to the gas cooler or upstream from the gas cooler, whereby the ash content entrained with the product gas increases and the sticking of condensing tar compounds on the heat surfaces decreases.

    摘要： A method of combusting oil shale or fuel having similar properties as oil shale in a circulating fluidized bed boiler. The method includes the steps of (a) introducing fuel into a furnace of the circulating fluidized bed boiler, (b) introducing primary oxygenous gas through a bottom grid of the furance, and (c) introducing secondary oxygenous gas to the furnace at a first level above the level of the bottom grid. The primary oxygenous gas is introduced to the furnace at a rate providing below the first level a fluidizing velocity of less than 2.5 m/s, and the primary and secondary oxygenous gases are introduced to the furnace in such a way that the fluidizing velocity below the first level is less than 70% of the fluidizing velocity in the upper portion of the furnace.

    摘要： A method of reducing the nitrogen oxide level in the flue gases issuing from combustion units by introduction of reducing agents into contact with gases containing nitrogen oxides in first and second reducing stages, is provided. The first reducing stage is a non-catalytic stage (e.g. at temperatures over 800.degree. C.), while the second stage is a catalytic stage (e.g. at temperatures of about 300-400.degree. C.). A steam generation boiler with improved nitrogen reduction facilities is also provided. The amount of nitrogen oxides in the hot gases is reduced in the combination of the first and second reducing stages while producing steam in a steam generation boiler system, thus resulting in gases essentially free from nitrogen oxides while eliminating the possibility of NH.sub.3 (or other reducing agent) slip in the exhausted flue gases. Heat transfers in a convection section as used to establish stabilized temperature conditions for catalytic reduction.

    摘要： Network presence of a computing device in a cloud computing network is maintained while power consumption of the computing device is reduced. When the computing device is determined to enter an idle state, at least some of the operations of the computing device running in a virtual machine environment are migrated to a server within the cloud computing network while maintaining connectivity of the computing device to the cloud computing network. When the computing device is determined to be in the idle state, the computing device is put into a sleep mode to reduce power consumption of the computing device. When the computing device is determined to be in an active state, the computing device is woken, and the migrated operations are returned from the server to the computing device. This reduces power consumption of the computing device while maintaining the network presence of the computing device in the cloud computing network.
