Abstract. The large number of spatially distributed earth observation products, i.e. time series of surface emissions and reflectances at different wavelengths with increasing spatial resolution, contribute to the derivation of surface characteristics, e.g. vegetation or soil parameters in the environmental sciences. These derivatives usually build upon complex algorithms consisting of atmospheric corrections and process descriptions. The testing scheme presented here seeks a different approach to identifying these surface characteristics that control the generation of such observation time series. Spatially distributed patterns of these characteristics of different persistence usually dominate parts of a time series because of their very specific reaction to and interaction with environmental influences. We test these characteristics' patterns for their existence in a rotated vector space of elementary patterns derived from a principal component analysis of an observational time series. With the result of this test we can then make valid assumptions, e.g. with regard to the importance of the surface properties for the emittance or reflectance, or their spatial uncertainties. We demonstrate the functionality of this rather simple test algorithm for a synthetic and fully traceable example, and an application in a medium hydrological catchment for a time series of thermal satellite data. Possible future applications for this scheme are the prioritization and improvement of model input, data assimilation, or the evaluation and validation of model output.

Display Performance

In recent years, screen soft proofing has matured with the development of color management and display technology, and it has become the direction of printing development and the key of promotion. This article aimed at raising a testing scheme of display performance and adjusting scheme of corresponding display parameters, on this account to test the professional display’s performance, adjust display parameters and make color management. At the same time with reflecting the actual situation of display, a stable and accurate color reproduction environment was provided for screen soft proofing. After that, evaluations were carried out to evaluate printing quality of screen soft proofing on the condition that display’s performance was good, consequently the differences between proofing effects and final printing were studied. The result shows that this testing scheme of display performance can reflect the truth of display which is tested in this paper, the display after adjusted and color management according to this scheme shows good effect in the ability of screen analog proofing original, it can approach the requirements of the printing proofing.

Testing Scheme

Floor slab static load test is a important method to judge the performance and carrying capacity of the slab. This paper, with the background of a factory frame-structure slab, introduced the testing scheme, the details of the testing process as well as the test results. The testing cases provide a useful reference for the same type of project.
