For the issue of multi-component system health assessment, an approach of steady algebraic system model learning from the condition data collected over the system serving period was discussed. Faced with the problem of measurement deficiency and inter-component coupling in system working process modeling and drift evaluation, an inclusive data-driven framework supported with corresponding domain knowledge...
The administration of hot spring in Taiwan has collected and checked the data of hot spring level these years. Unique temperature and quality of the hot spring usually caused the device recorded and missing data. The data analysis used the gray theory in order to supplement the data of hot spring level.
The administration of hot spring in Taiwan has collected and supervised the data of hot spring level. However, the data is usually collected incompletely due to the special temperature and characteristics of hot spring, which influenced the function of instruments. For the purpose of the data analysis of hot spring level, the gray theory was conducted in this study to supplement the data of hot spring...
In this paper, a fractional-order control (FOC) based approach is proposed for piezo-actuated nanopositioning stage. The developed controller is not only to suppress the vibration of the low-damped resonant mode, but also to minimize the tracking error for nanopositioning applications. Firstly, an inverse hysteresis compensator is utilized to compensate for the inherent hysteresis nonlinearity of...
The main object of workflow description is to map business requirements quickly and accurately mapped to business process. An approach of business semantic-oriented workflow description method is proposed aiming at the current workflow description method lack of resource allocation means oriented business staff. It provides a description way that business staff familiar with through which business...
With the rapid increase in the amount of multimedia data, the researches on semantic information retrieval are facing a very challenging problem - the number of positive data instances with the target concept/object/event compared with the number of negative data instances without the target concept/object/event is much smaller, which is also called the data imbalance issue. Therefore, one of the...
In modern Web Applications, how to design a flexible and changeable report is always one of the key problems to web software designers and developers. Here by analysis the web report tasks and its characteristics, based on the research of the software bus technologies, component technologies and template technologies, with software bus and template technologies illustrates a task driven based generic...
The upconversion fluorescence spectra of Er3+/Yb3+: PLZT exciting at 980 nm were measured from 10K to 320K. A model for the dynamics of frequency upconversion processes was proposed. Based on the model, the upconversion luminescence intensities curves as a function of temperature were fitted and the temperature characteristics of upconversion luminescence were discussed.
