Aiming at fault detection rate (FDR) and fault isolation rate (FIR), testability demonstration technology is relatively mature. As an extension of testability technology, PHM (Prognostics and Health Management) provides a more sophisticated form to quantify and predict equipment health state and remaining useful life (RUL). Therefore, many researches attach importance to the prognostic validation...
Particle size is the key technical index of grinding process, but it is difficult to be measured online directly, and the lab analysis has large-time delay. Combined with the advantage of soft-sensor modeling based on support vector regression (SVR), a soft-sensor approach for particle size of grinding process with SVR is proposed. Firstly, the empirical formulae are used to roughly determine the...
In this paper, we focus on evaluating different storage strategies of different kinds of data and their index stored in Punt Table. Punt Table is a NoSQL database designed for elastic objects storage. Punt Table uses a schema-free way to store and get the objects and builds indices to support querying the fields inside the objects. In order to achieve high throughput and low latency, Punt Table is...
For the massive remote image file's management, we build the file catalog system of data application based on the part whole ontology of spatial relation. The method is that we analyzed the attributed item of image metadata and calculated the weight for application, then build the catalog concept level relation, calculated the similitude degree of the image attributed item and catalogue node to build...
