摘要： Techniques are disclosed for accessing a dimensional data model when processing a query. In one embodiment, the query is processed by performing a two-stage zigzag join operation including a zigzag main join and a zigzag back join. The zigzag main join is configured to generate a set of row identifiers of fact records satisfying any local predicates in the query. The zigzag back join is configured to generate query results based on the set of row identifiers. The query results are returned responsive to the query.

摘要： Markup language node level hash join operations for evaluating a query language query are performed. The markup language node level hash join mechanism, i.e. the “XHashJoin” operator, is a multi-way join operator that uses two hash tables, BUILD and PROBE, to intersect document nodes from multiple index scans and to buffer intermediate query results. The BUILD hash table stores document nodes matching the predicates of a query, and buffers document nodes satisfying extraction nodes, of each portion of the query up to a current portion of the query being evaluated. The BUILD hash table and the PROBE hash table are switched at each portion of the query being evaluated. Query results are generated by linking document nodes buffered in the BUILD hash table based on the semantics of each extraction node.

摘要： A microfluidic system has an electroosmotic flow pumping means for propelling fluids through a series of microchannels and selection valves. Pump channels are configured in groups which may be fabricated singly or in multiple groups onto a substrate. A tube filled with an immobilized polymer provides a means to apply voltages across pump channels, while prevents passages of fluids through it. It also avoids electrolysis and bubble formation in or close to the microfluidic channels. The selection valves provide for routing functions within the microfluidic system and can also be configured to route fluids outside the system. A rate monitoring system is provided for determining and compensating for flow rates. In one application the microfluidic system may be configured to operate as a small volume pipettor or other fluid transport or analysis device. A micro-dialysis jacket is additionally provided to permit desalting, pH adjustment, concentration adjustment, and other functions.

摘要： Method and apparatus for flow injection analysis (FIA) using an electroosmotic pump. The apparatus includes: an electroosmotic pump having a grounding joint; a sample injection valve for introducing a sample into a carrier stream which valve is in fluid communication with the grounding joint by way of a conduit; a dispersion coil in fluid communication with the sample injection valve; and a detector which is in fluid communication with the dispersion coil. The grounding joint couples the electroosmotic pumping system and the FIA system but electrically isolates them.Generally, the method utilizes one fluid which is electroosmotically pumped to propel a carrier for flow injection analysis at a controllable flow rate. More specifically, the method includes the steps of: adding a sample to a liquid carrier stream to form a sample zone in the carrier stream; flowing a liquid pumping stream by electroosmosis; and connecting the pumping stream with the carrier stream to propel the carrier stream.
