Abstract: A computer is programmed to process a continuous query that is known to perform a new aggregation on one or more stream(s) of data, using one or more other aggregations on the stream(s). The computer creates an operator to execute the continuous query, and schedules the operator for execution in a specific order. In several embodiments, the computer determines the order based on dependency of the new aggregation on other aggregation(s), and on the order of performance of the other aggregation(s). The new aggregation is scheduled for performance after performance of each of the other aggregations. The computer is further programmed to pass results of the other aggregations to the new aggregation, by execution of a predetermined function. Support for use of the other aggregations results within the new aggregation eliminates redundant computation of the other aggregations within the new aggregation. The new aggregation may be user defined or built-in.

Abstract: A new continuous query to a data stream management system (DSMS) may use a stream or a relation which may or may not be used by continuous queries previously registered in the DSMS. The DSMS is programmed to modify an execution plan to accommodate execution of the new query while continuing to execute the previously registered continuous queries. The modified execution plan may include new operators and/or share existing operators. The DSMS is programmed to cause operators which output a relation to propagate a current state of the relation to each newly-coupled operator that uses the relation. The current state is propagated only to operators that have been newly coupled and have thus not yet received any state information previously. After propagation of current state to newly-coupled operators, results of processing any new data for the relation are supplied to all operators coupled thereto, including newly-coupled operators and existing operators.

Abstract: A computer is programmed to accept a command to create a new aggregation defined by a user during execution of continuous queries on streams of data. The computer is further programmed to thereafter accept and process new continuous queries using the new aggregation, in a manner similar to built-in aggregations. The user typically writes a set of instructions to perform the new aggregation, and identifies in the command, a location of the set of instructions. In response to such a command, the computer creates metadata identifying the new aggregation. The metadata is used to instantiate one aggregation for each group of data in a current window, grouped by an attribute identified in a new query.

Abstract: A new continuous query to a data stream management system (DSMS) may use a silent relation whose source does not provide any heartbeats. During execution of any given operator, the DSMS processes data from one input (“active input”) using its time stamp as if the same time stamp is received from another input whose relation has fallen silent (“empty input”), if one or more predetermined conditions are met. One predetermined condition is that the empty input's operator has all its own inputs silent. And another predetermined condition is that a maximum time stamp that is currently present among all the inputs of the empty input's operator is equal to a time stamp that was last received from these same inputs. When both conditions are met, previously received data from the empty input is time stamped with the same time stamp as the most recently received data from the active input.

Abstract: A telecommunication receiver provided according to the present invention is implemented to receive a first signal containing information and noise on a first set of sensors and a second signal containing only noise on a second set of sensors. Receiver then decodes the information using first signal and second signal. In one embodiment, a bonded DSL receiver with k signals sensors is implemented with additional s number of noise only sensors to receive only noise. Accordingly, joint demodulation is performed using signals received on k signals sensors and s noise only sensors. The noise sensor is implemented in common mode.

Abstract: The invention discloses an improved process for producing an intermediate to produce large quantity of 2-(Phenyl methyl thio)-3-pyridine carboxylic acid. The process comprises reacting 2-chloro-3-cyanopyridine with benzyl mercaptan in presence of a base and an aprotic solvent. The resulting intermediate 2-(phenyl methyl thio)-3-cyanopyridine is hydrolyzed in presence of a base in an autoclave and isolated under acidic condition to get the desired product.

Abstract: A program creates a unitary mask for use over a whole image, with one pattern. The mask need not be full image size; it may be tiled. In the field a printer forms a mask and prints with it, best in the same session, before another image needing another mask, whether due to different image activity or type, or operating conditions. Constraints are controlled to ensure solution. Printout can start before a mask (even the part needed to finish a top swath) is done, going columnwise in each swath. In other invention facets, a program forms a mask of size significant relative to the program and prints with it. Other facets check print conditions and form adapted masks; or find nozzles that cannot back up a known-failed nozzle and to back it up form masks with all able nozzles; or assess image activity and inject mask randomness accordingly.

Abstract: An improved process for producing 4-dimethyl amino pyridine is provided. The process comprises quaternizing pyridine with a suitable quaternizing agent in the presence of organic solvent, isolating the resulting salt and aminating the salt, N-[4-pyridyl] pyridinium chloride hydrochloride, with N,N-dimethyl formamide. The resultant reaction mass is hydrolysed in the presence of a base, extracted with an aromatic solvent and distilled under vacuum to produce 4-dimethyl amino pyridine.

Abstract: Described is a dynamic multi-pass print mode correction method which corrects for malfunctioning or inoperable ink ejection elements by substituting a fully functioning ink ejection element. The method comprises the steps of obtaining a printmask; identifying ink ejection elements which are malfunctioning; ascertaining potential replacement ink ejection elements from the printmask for the ejection elements which are malfunctioning; selecting replacement ink ejection elements from the potential replacement ink ejection elements; and modifying the printmask by removing the malfunctioning ink ejection elements from the printmask and replacing them with the selected replacement ink ejection elements.

Abstract: Full-color swaths produced in opposite scanning directions are offset to conceal or eliminate the color-cast effects of the varying deposition order which is inherent in bidirectional operation with in-line pens. Offsets are produced by unequal printing-medium advance between oppositely directed sweeps, or by alternating forward and reverse advance steps between oppositedly directed sweeps, or by both unequal and alternate-reverse steps; or by pen masking. Color-cast effects of varying drying/wicking time, too, are minimized.
