Information Criteria are a core component of the COBIT Framework that describes the intent of the objectives, namely the control of: Effectiveness deals with information being relevant and pertinent to the business process as well as being delivered in a timely,correct, consistent and usable manner. Efficiency concerns the provision of information through the optimal use of resources. Confidentiality concerns the protection of sensitive information from unauthorised disclosure. Integrity relates to the accuracy and completeness of information as well as to its validity in accordance with business values and expectations. Availability relates to information being available when required by the business process now and in the future. It also concerns the safeguarding of necessary resources and associated capabilities. Compliance deals with complying with the laws, regulations and contractual arrangements to which the business process is subject, i.e., externally imposed business criteria as well as internal policies. Reliability relates to the provision of appropriate information for management to operate the entity and exercise its fiduciary and governance responsibilities.
Video point information standard management method and system based on inverse geography joint checking
The application discloses a video point information standard management method and system based on reverse geographical joint checking, which comprises the following steps: performing joint checking on name semantics and geographical semantics through reverse geographical analysis results of latitude and longitude, and calculating geographical consistency scores; and based on the geographical consistency scores and the standard entity set, automatically completing the missing device attributes. Through multi-field preprocessing + candidate slot map joint modeling, the application can fully utilize the complementary information in the original code, attributes, latitude and longitude, and installation description; the BERT-BiGRU-CRF model and its training process are disclosed through prompting enhancement, which can avoid the problem of insufficient disclosure of the entity recognition model, and improve the entity recognition accuracy of non-standard point names; through the dynamic graph updating mechanism, preferably in the incremental updating mode, the application can continuously absorb new aliases, new device types and artificial review results, and avoid long-term static failure of the knowledge graph.

A radar motion parameter estimation method and device based on information criterion value
This invention provides a radar motion parameter estimation method and apparatus based on information criterion values. It acquires raw radar echo data, performs range processing and target extraction to obtain a target slow-time complex sequence. Based on the target slow-time complex sequence, it constructs multi-order motion candidate models, calculates the residual sum of squares, and calculates the information criterion value based on the residual sum of squares. The optimal model order is determined based on the information criterion value, and the target radial motion parameters are inverted and output based on the phase coefficients corresponding to the optimal model order. Instead of pre-fixing the use of a first-order, second-order, or third-order model, it determines the optimal model order after constructing multi-order candidate models and evaluating them using the calculated information criterion value. This approach adaptively determines the appropriate motion model order for the target based on the phase evolution characteristics of the signal itself, and completes motion parameter estimation accordingly. This ensures estimation accuracy while suppressing unnecessary model complexity, thus improving its engineering application value.

Propeller numerical prediction thrust spectrum result verification and validation method
This invention discloses a method for verifying and confirming numerical prediction thrust spectrum results of propellers, belonging to the field of computational fluid dynamics (CFD) result verification and confirmation. While maintaining consistency between the physical model and boundary conditions, this invention encrypts the CFD calculation settings with joint discrete parameters and quantitatively characterizes simulation errors and uncertainties based on Richardson extrapolation. This invention employs the Lomb-Scargle periodogram method to directly process non-uniformly sampled data, avoiding spectral distortion caused by resampling interpolation and improving the accuracy of spectrum estimation. This invention automatically selects the optimal AR model order through information criteria, models colored noise backgrounds in actual engineering, and achieves adaptive noise modeling. This invention simultaneously evaluates the statistical significance of the global maximum peak value and each expected harmonic frequency in a single Monte Carlo simulation cycle. This invention uses a block bootstrap method to calculate the frequency band power confidence interval, maintaining the local correlation of the time series and achieving reliable confidence interval quantification.

Background data processing method and apparatus, device, and medium
This invention relates to the field of data processing technology, and discloses a backend data processing method, apparatus, device, and medium, comprising: standardizing and uploading the basic equipment information of the target device to a backend server; using a preset semantic network for semantic deconstruction and reorganization to generate a structured semantic knowledge graph, thereby deeply revealing the inherent logical relationships between data. Based on this graph, a business indicator heatmap is drawn in conjunction with real-time backend business data to intuitively present risks and performance bottlenecks; a real-time business recommendation strategy is generated in conjunction with customer data to achieve precise marketing decisions; simultaneously, the business logic is modeled and associated with business data to obtain a visualized business process graph, clarifying the business logic and data flow. Finally, the heatmap, recommendation strategy, and process graph are integrated to generate a unified business navigation interface. This invention improves the data integration capability and semantic parsing capability of complex business data during backend data processing.
