The present disclosure provides a method and system for controlling peak power consumption, which dynamically controls frequency by monitoring the load in real-time, thereby reducing the power consumption, and providing sufficient computing performance while controlling peak power consumption. The method and system for controlling peak power consumption of the present disclosure monitor the load in real-time, and reduce power consumption by dynamically and intelligently controlling the operating frequency, to achieve a balance between performance and power consumption, such that the chip works at the highest frequency when the peak power consumption does not exceed the load threshold, thereby effectively improving the work efficiency while achieving the power consumption control.

The present invention relate to a binderless molecular sieve catalyst and a process for preparing the same, which are mainly useful for solving the problems of the current catalysts, such as lower activity, less pore volume and worse diffusivity. The present invention relates to a novel binderless molecular sieve catalyst, comprising, based on the weight of the catalyst, 90-100 wt. % of a molecular sieve, 0-10 wt. % of a binder, and 0-10 wt. % of an anti-wear agent, wherein said catalyst has a pore volume of 0.1-0.5 ml/g, an average pore diameter of 50-100 nm, and a porosity of 20-40%; the anti-wear agent is selected from the rod or needle-like inorganic materials having a length/diameter ratio of 2-20. Said catalyst has the advantages of higher activity, greater pore volume, larger average pore diameter and porosity, and better diffusivity, and well solves said problems and can be used for the industrial preparation of binderless molecular sieve catalysts.

Systems and method for tile-based compression are disclosed. Image data, such as a frame, may be divided into tiles. The tiles may be sized based on a size of a line buffer. Tiles are compressed and decompressed individually. As portions of the image frame are updated, corresponding updated tiles may be compressed and stored. Likewise, as tiles are accessed they may be de-compressed and streamed to a requesting device. In some embodiments, a decoder operable to decompress tiles may be interposed between a memory device and a requesting device. Data encoding one or more compressed tiles may be grouped to enable decompression at a rate of four pixels per clock cycle. Methods for compressing image data including both RGB and RGB&#x3b1; components are disclosed.

Changes to a hierarchical organizational structure may be stored in different versions of a data structure depicting the hierarchical organizational structure. Each of these versions may include a validity period field representing a time period that the hierarchical organizational structure depicted in the version accurately reflects the organizational structure of the organization. Each of the versions may also be designated as active or inactive. In some instances, each of the versions may be designated as inactive except for a version that reflects the organizational structure of the organization at a particular time, which may change over time. Historical copies of versions may be stored and subsequently recalled to identify an organizational structure that was in effect at a particular time in the past. The recalled version may then be used to limit the results of a query to a selected node of the historical organizational structure.

Enablement of quasi time dependency in organizational hierarchies

A working context is implemented for a business application by associating business objects with context categories that organize a user's favorite business objects. A working context that is specified by including at least one of the defined business categories can be applied to a business application by providing the corresponding favorite business objects to the business application for an execution of the business application.

Disclosed are new approaches to Multi-dimensional filtering with a reduced number of memory reads and writes. In one embodiment, a filter includes first and second coefficients. A block of a data having width and height each equal to the number of one of the first or second coefficients is read from a memory device. Arrays of values from the block are filtering using the first filter coefficients and the results filtered using the second coefficients. The final result may be optionally blended with another data value and written to a memory device. Registers store results of filtering with the first coefficients. The block of data may be read from a location including a source coordinate. The final result of filtering may be written to a destination coordinate obtained by rotating and/or mirroring the source coordinate. The orientation of arrays filtered using the first coefficients varies according to a rotation mode.

Low power and low memory single-pass multi-dimensional digital filtering

A process for producing light olefins from methanol and/or dimethyl ether is disclosed. It comprises: (a) introducing a feed comprising methanol and/or dimethyl ether into a fluidized-bed reactor from its bottom, and contacting the feed in a dense phase zone and a transition zone of the fluidized-bed reactor with a catalyst, to form an effluent I comprising unreacted feed, reaction products and entrained solid particulate catalyst; (b) introducing a terminating agent consisting of water, alcohol, ether, hydrocarbons, and aromatic at upper portion of the transition zone and/or lower portion of a gas-solid separating zone of the fluidized-bed reactor into the effluent I, to give an effluent II; and (c) passing the effluent II into the gas-solid separating zone in upper portion of the fluidized-bed reactor, where gas-solid separation is accomplished to give a gaseous product stream and solid catalyst.

The present invention provides a process for producing lower olefins by catalytic cracking a feedstock comprising an olefins-enriched mixture containing C4 or higher olefins and optionally an organic oxygenate compound. The technical problem mainly addressed in the present invention is to overcome the defects presented in the prior art including low yield and selectivity of lower olefins as the target products, and short regeneration period of catalyst. The present process, which is carried out under the conditions of catalytic cracking olefins and adopts as a feedstock an olefins-enriched mixture containing one or more C4 or higher olefins and optionally an organic oxygenate compound, comprises the steps of: a) letting the feedstock firstly enter a first reaction zone to contact with a first crystalline aluminosilicate catalyst having a SiO/AlOmolar ratio of at least 10, to thereby produce a first reaction effluent containing lower olefins; b) letting the first reaction effluent enter in turn at least one second reaction zone to contact with a second crystalline aluminosilicate catalyst having a SiO/AlOmolar ratio of at least 10, to thereby produce a second reaction effluent containing lower olefins; and c) separating lower olefins from the second reaction effluent; wherein the reaction temperatures in the first and second reaction zones are controlled. The present process, which desirably solves the above technical problem, can be used in industrial production of lower olefins.
