The invention discloses a transformer partial-discharging mode recognition method based on a singular value decomposition algorithm, and the transformer partial-discharging mode recognition method comprises training model and classification recognition process, and the method comprises the steps of firstly establishing an artificial defect experimental environment, collecting data samples, calculating statistic characteristic parameter of each sample to form a data sample matrix; conducting singular value decomposition for the sample matrix, determining an order of an optimum reserved matrix by judging whether the characteristic of the reserved matrix is obvious or not, and obtaining a type characteristic space description matrix after the dimensionality reduction and a class center description vector group; preprocessing the sample to be recognized to obtain a sample vector, utilizing the type characteristic space description matrix to linearly convert the sample vector to obtain the sample description space vector after the dimensionality reduction, and then calculating the similarity of the vector with each vector in the type vector group to obtain a classification judgment result. The algorithm is simple and high efficient, reliability for distinguishing an interference signal and a discharging signal in the partial-discharging detection can be realized, and the accuracy for diagnosing the partial-discharging mode can be improved.

A pop-up window is generated when the user clicks on the slider within the scroll bar display object. The pop-up window displays information from one or more categories in a currently selected list entry, including the category on which the list is currently sorted. As the user moves the slider, the information in the pop-window is updated to reflect the current location in the list, as determined by the current location of slider within the scroll bar. When the user stops scrolling, i.e. releases the scroll slider, the matching entry for the current location becomes highlighted, and the system enters a search mode. In the search mode, the disclosed system continues to display the pop-up window for a few seconds to allow the user the option of editing the text in the pop-up (as derived from the current position in the list) in order to go to another entry in the sorted list. Accordingly, the sorted category information loaded from the current list entry becomes editable within the pop-up window with a type ahead feature allowing the user to see and select from and search based on information from list entries in the sorted data that closely match the text that the user has typed into the pop-up window. When the user presses “Enter”, the current view and scroll bar position are relocated to reflect the position of the entry matching the selected search information.

A storage system that stores verify commands for all the write commands requiring verification in a verify-list that will be processed as a background task is described. The verify-list can include coded data fields that flexibly designate selected alternative states or possibilities for how and where the user data is actually stored. Alternatives for the verify-list include storing the actual raw data, no data, the data in compressed form, a CRC type signature of the data and / or a pointer to a backup copy of the data that is stored either in non-volatile memory such as flash memory or on the disk media in a temporary area. In case of a verification error in various alternative embodiments the user data can be recovered using the backup copy in the verify-list in the write cache, the backup copy in flash memory or on the disk, or from the host.

The present invention relates to digital signature operations using public key schemes in a secure communications system and in particular for use with processors having limited computing power such as ‘smart cards’. This invention describes a method for creating and authenticating a digital signature comprising the steps of selecting a first session parameter k and generating a first short term public key derived from the session parameter k, computing a first signature component r derived from a mathematical function using the short term public key, selecting a second session parameter t and computing a second signature component s derived from a second mathematical function using the second session parameter t and without using an inverse operation, computing a third signature component using the first and second session parameters and sending the signature components (s, r, c) as a masked digital signature to a receiver computer system. In the receiver computer system computing a recovered second signature component s′ by combining a third signature component with the second signature component to derive signature components (s′, r) as an unmasked digital signature. Verifying these signature components as in a usual ElGamal or ECDSA type signature verification.

The invention provides a method used to provide a search result. The method comprises the steps that according to a search keyword input by a user in a current search type, type characteristic information matched with the search keyword is acquired; search is conducted based on the current search type, and an initial search result corresponding to the search keyword is acquired; according to the type characteristic information, the initial search result is adjusted; and a search result obtained after adjustment is provided to the user. According to the scheme provided by the invention, a potential search demand which may be possessed by the user aiming at the search keyword can be known; and the initial search result is adjusted based on the type characteristic information, so the search result obtained after the adjustment can satisfy the user's potential search demand, and search efficiency is increased greatly.
