The present provide a technical solution by introducing a method of detecting a liquid crystal display panel, characterized in that the method includes a) providing an all-connection lit-up fixture having a plurality of probes. And b) performing a lit-up test by establishing an electrical coupling between the probes and a plurality of contacts on the liquid crystal display panel. By this arrangement, the liquid crystal display panel can be readily pin-pointed the defects after the shorting bar is cut off as the fixture provided can readily restore the lit-up test Accordingly, the capability of lit-up test is therefore enhanced.
A trade-off exists between the and methods to calculate the marginal likelihood in Bayesian estimation. Using the Markov Chain Monte Carlo method, we demonstrate that the performance of the two methods is fairly close.

Different-sized hollow SiO 2 spheres of 249-1348 nm in diameter were successfully prepared by using Na 2SiO 3 as the precursor and using polystyrene and polystyrene-methyl acrylic acid latexes as the templates. The diameter and shell thickness of the hollow SiO 2 spheres increase with increasing the latex template diameter at a given mass ratio of SiO 2 to latex template. The diameter and shell thickness of the hollow SiO 2 spheres also increase with increasing the mass ratios of SiO 2 to latex template. The presence of carboxylic acid groups on the surfaces of polystyrene-methyl acrylic acid latex templates favors the formation of dense and uniform SiO 2 shells. The hollow SiO 2 sphere is constructed by mesoporous shell with large specific surface area. When glyphosate is used as a release model chemical, glyphosate release rate is tuned by varying the shell thickness.

The ZiYuan-3 (ZY-3) satellite, equipped with three-line array scanners, is China’s first civilian stereo mapping satellite. In this paper, the first assessment of the stereoscopic capacities of the ZY-3 imagery for building height estimation in heterogeneous urban areas is performed. Digital surface models (DSMs) are generated and optimized by different stereo pairs of a ZY-3 triplet for the city of Wuhan, China. The normalized DSMs (nDSMs) are computed as the height of the off-terrain objects by using morphological top-hat by reconstruction of the DSMs. We adopt random forest classification and object-based building segmentation to detect the buildings from the orthographic image, and estimate the building height by assigning the maximum nDSM value within the building regions. The actual heights of 400 buildings are used as reference data. Comparisons between the building heights extracted from the different stereo pairs are presented, indicating a higher accuracy by the nadir-forward stereo pair. The performance of the ZY-3 triplet is also compared with that of a WorldView-2 (WV-2) stereo pair, better result is achieved by ZY-3 nadir-forward image pair.
Six segments of quadratic Bézier curve are joined together according to some geometrical rules to approximate fold shape. In a classification of folds based on this method, an ideal fold shape is determined by two parameters. The first one, uc, termed the axial lift-up ratio of the central part, generates the folds within a broad spectrum of forms ranging from box folds to chevron folds. The other one, γ, is the interlimb angle. In the quantitative description of complete folds with multiple layers, three new parameters, θ, T and E are used to describe the deflection angle of the axial plane, the thickness increment of hinge zone and the limb elongation, respectively. Based on the modeling method, the program “Bézier Fold Profiler” has been developed, with which most types of folds can be simulated by varying thirteen parameters. Two description methods, complete fold description and individual layer description, can be used for the quantitative analysis of folds. The description methods are carried out by the visual matching of the fold profile displayed on-screen from an imported digital image. The layer curves of the model are displayed on the fold image. This method has the advantage of speed and simplicity.

From the large-NcN_c QCD point of view, baryonia, tetraquark states, hybrids, and glueballs are studied. The existence of these states is argued for. They are constructed from baryons. In Nf=1N_f=1 large-NcN_c QCD, a baryonium is always identical to a glueball with NcN_c valence gluons. The ground state 0-+0^{-+} glueball has a mass of about 2450 MeV. f0(1710)f_0(1710) is identified as the lowest 0++0^{++} glueball. The lowest four-quark nonet should be f0(1370)f_0(1370), a0(1450)a_0(1450), K*0(1430)K^{\ast}_0(1430) and f0(1500)f_0(1500). Combining with the heavy quark effective theory, spectra of heavy baryonia and heavy tetraquark states are predicted. 1/Nc1/N_c corrections are discussed.
At present, great demands are posed on software dependability. But how to elicit the dependability requirements is still a challenging task. This paper proposes a novel approach to address this issue. The essential idea is to model a dependable software system as a feedforward-feedback control system, and presents the use cases + control cases model to express the requirements of the dependable software systems. In this model, while the use cases are adopted to model the functional requirements, two kinds of control cases (namely the feedforward control cases and the feedback control cases) are designed to model the dependability requirements. The use cases + control cases model provides a unified framework to integrate the modeling of the functional requirements and the dependability requirements at a high abstract level. To guide the elicitation of the dependability requirements, a HAZOP based process is also designed. A case study is conducted to illustrate the feasibility of the proposed approach.
