The Standard Model of particle physics is the theory describing three of the four known fundamental forces (the electromagnetic, weak, and strong interactions, and not including the gravitational force) in the universe, as well as classifying all known elementary particles. It was developed in stages throughout the latter half of the 20th century, through the work of many scientists around the world, with the current formulation being finalized in the mid-1970s upon experimental confirmation of the existence of quarks. Since then, confirmation of the top quark (1995), the tau neutrino (2000), and the Higgs boson (2012) have added further credence to the Standard Model. In addition, the Standard Model has predicted various properties of weak neutral currents and the W and Z bosons with great accuracy.
Methods and structure for batch processing event history processing and viewing
InactiveUS7249356B1Efficient captureGood conditionElectric testing/monitoringMultiprogramming arrangementsUser needsBatch processing
A batch event historian gathers, stores and presents data regarding a batch process where relationships among the various elements of data are automatically derived by an executive program. A persistent store includes structure corresponding to the relationships defined among procedural elements and equipment in accordance with batch processing industry S88.01 standards. The executive program gathers event information generated by the batch process and derives the relationships among the events in accordance with these industry standard models. Storage and corresponding retrieval and presentation of such historical data is thereby simplified for a user because the user need not manually configure the historian programs to derive the relationships. Association of any continuous data log with event information is automated thereby obviating the need for manual configuration by a user to establish such associations.

The invention relates to a self-adaptive method for evaluating the pronunciation of a computer language learning system, comprising the following steps of: establishing a voice recognition system; carrying out the segmentation of initials and finals of voice data based on the voice recognition system and restricting the recognition of initials and finals at the boundary and the tone; calculating posterior probability of all the initials and finals and the tone according to the result of restriction of boundary recognition and the segmentation and selecting self-adaptive data according to the preset threshold; carrying out self-adaptation for an acoustic model in the recognition system according to the selected self-adaptive data; carrying out the second segmentation and recognition by using the acoustic model after the self-adaptation; using the final segmentation and recognition result to extract evaluating parameters; the invention selects a proper self-adaptive corpus by posterior probability, not only can reduce error of a recognizer caused by the differences of an actual speaker and a standard model tone, use environment and channels but also can avoid the bias of the standard model when in self-adaptation so as to be incapable of evaluating the pronunciation of the speaker accurately.
