Concrete thermal parameters in a natural pouring environment are essential inputs for simulating the temperature field of concrete dam. This paper proposes two-stage inversion method dam based on optimal measuring point selection to improve accuracy parameters. Firstly, is presented and response sensitivity points when disturb taken as critical evaluation index. And then, an model established s...

The development of remote sensor technology makes it convenient to obtain multiscale satellite data sets, but selecting data with an appropriate scale has become a problem. We propose improvements based on modified average local variance (MALV) for selecting the optimal spatial resolution of multiband images. One improvement is computing the mean MALVs of all bands, and the other is computing t...

We use “selecting” as a general term for selection processes, including filtering, retrieval, routing, and searching. The search for recorded knowledge in a digital library environment is examined in terms of selection at three levels: 1. Selecting which library (repository) to look in; 2. Selecting which document(s) within a library to look at; and 3. Selecting fragments of data (text, numeric...
