A system and method for estimating the position of wireless devices within a wireless communication network combines measured RF channel characteristics for the wireless device with one or more predicted performance lookup tables, each of which correlates an RF channel characteristic to some higher order network performance metric and/or a position within an environmental model. Measured RF channel characteristics for wireless devices are compared against the performance lookup tables to determine the sent of lookup tables that most closely match the measured RF channel characteristics. The positions within the environmental model corresponding to the selected set of matching lookup tables are identified as possible locations for the wireless device. The performance lookup tables are uniquely constructed by site-specific location, technology, wireless standard, and equipment types, and/or the current operating state of the communications network.

A model system for simulating the performance of a subterranean well, starts with a base model wherein input logging data, pressure transient data and PVT data is introduced into the base model. A numerical interpreter then calculates the predicted performance of the well. A match system compares actual performance data with calculated performance data based on the base model through reiterative loop for modifying the base model to provide a match between the actual performance data and the predicted performance data to optimize the base model. The method for generating the optimized performance data in accordance with the subject invention incorporates the steps of introducing known pressure transient data, well logging data and PVT data for the well into a base model and producing a performance prediction from the base model. These results are compared with actual performance data and the model is modified to generate a performance prediction that matches the actual performance for producing an optimized model. The method is particularly useful because it accounts for and adjusts the performance prediction based on non-Darcy factors effecting the fluid parameters in the well.

Systems and methods are disclosed for monitoring and managing data transactions, such as SQL transactions. In certain examples, a management subsystem generates an alert identifying degrading database transactions to facilitate preventative tuning or other maintenance. In particular, a monitor module tracks performance measurements (e.g., logical reads) of select transactions. A modeler correlates the performance measurements and assigns first performance model(s) to represent the performance measurements and predicted performance measurements of a particular transaction. A trend change module detects a significant change in a trend and/or variance of the performance measurements and can cause the modeler module to generate a second performance model to represent at least a portion of the performance measurements and the predicted performance measurements of the particular transaction. An interface module triggers an alert when the second performance model indicates that the predicted performance measurements of the particular transaction are degrading at or above a threshold rate.
