Liexiao Dong, Yanbo Zhou, Tiantian Gong, Mingshan Wu, more

International Journal of Applied Ceramic Technology > 21 > 2 > 759 - 765

The environmental stability of barium calcium aluminate for impregnated cathodes is significant for storing impregnants and fabricating thermionic cathodes. In this work, two types of phase structures are obtained in the 612‐type aluminate. The Ba₃CaAl₂O₇ single‐phase structure is obtained if the crucible is uncovered after sintering for 300 min at 1200°C. In contrast, the Ba₃Al₂O₆ and BaCO₃ dual‐phase...

Journal of Algebra > 2017 > 489 > C > 138-164

Let R be a left noetherian ring and S a right noetherian ring, and let X be a subcategory of finitely generated left R-modules and BSR a finite (R,S)-bimodule. As a generalization of the Auslander transpose, replacing a projective presentation by an X-presentation and the functor HomR(−,R) by the functor HomR(−,B), we introduce the X(B)-transpose of an R-module M admitting an X-presentation.

Bin Yu, Xiaosheng Zhu, Yanbo Zhou

Algebras and Representation Theory > 2017 > 20 > 6 > 1571-1592

We compare relative cohomology theories arising from using different proper resolutions of modules. Criteria for the vanishing of such distinctions are given in certain cases, and we show that this is related to the generalized Tate cohomology theory. We also demonstrate that the two balance properties admitted by the two different cohomology theories are actually equivalent in some cases. As applications,...

Ruzhuang Zhang, Yanbo Zhou, Xiaochen Gu, Jun Lu

CLEAN – Soil, Air, Water > 43 > 1 > 96 - 103

Pine sawdust modified with citric acid (CA‐PS) is used as an adsorbent for the removal of Cu²⁺ and methylene blue (MB) from the single and binary compound systems. The initial pH has a significant effect on Cu²⁺ adsorption, but a relatively little effect on MB adsorption. The kinetic and isotherm studies indicate that the pseudo‐second‐order model and the generalized model provide the best correlation...

2012 IEEE 6th International Conference on Information and Automation for Sustainability > 163 - 166

2012 IEEE 6th International Conference on Information and Automation for Sustainability (ICIAfS)

Geospatial tools and techniques are becoming more important for land surveyors to do their off-location inspections of the urban areas. Accurate geocoded street-level images are the base of these tools. For these applications, an error of 2.5 meters is tolerable. However, the geographic coordinates provided by GPS have error up to 10 meters. In this paper we propose an automatic method to improve...
