Spatial/temporal indexing and information visualization genre for environmental digital libraries

Journal of Zhejiang University-science A(Applied Physics & engineering) 2005年第11期6卷 1235-1248页

作者： CHEN Su-shing GRUNWALD Sabine department of Computer ＆ Information science ＆ engineering University of Florida Gainesville Florida 32611 USA department of soil and Water science University of Florida Gainesville Florida 32611 USA

Protecting and preserving our environmental systems require the ability to understand the spatio-temporal distri- bution of soils, parent material, topography, and land cover as well as the effects of human activities on ecosystems. Space-time modelling of ecosystems in an environmental digital library is essential for visualizing past, present, and future impacts of changes occurring within such landscapes (e.g., shift in land use practices). In this paper, we describe three novel features, spa- tio-temporal indexing, visualization, and geostatistical genre, for the environmental digital library, Environmental Visualization and Geographic Enterprise System (ENVISAGE), currently in progress at the University of Florida.

Paddy rice samples were parboiled by soaking at 65℃ for 180 min and steaming at 96℃ for 2–10 min,and then dried to achieve the final moisture content of 11% ± 1%. The degree of starch gelatinization （DSG） andseveral quality attributes （head rice yield （HRY）, color value and hardness） of parboiled rice were *** showed that DSG （46.8%–77.9%）, color value （18.08–19.04） and hardness （118.6–219.2 N） allincreased following steaming. In contrast, the HRY increased （64.8%–67.1%） for steaming times between 2–4min but decreased （67.1%–65.0%） for steaming times between 4–10 min. Linear relations between DSG andcolor value （R2 = 0.87）, and DSG and hardness （R2 = 0.88） were observed. The suitable DSG of parboiled riceleading to the highest HRY was found to be 62.5%, obtained following 4 min of steaming.

Alternate row mulching optimizes soil temperature and water conditions and improves wheat yield in dryland farming

引用

Journal of Integrative Agriculture 2018年第11期17卷 2558-2569页

作者： YAN Qiu-yan DONG Fei LOU Ge YANG Feng LU Jin-xiu LI Feng ZHANG Jian-cheng LI Jun-hui DUAN Zeng-qiang Institute of Wheat Research Shanxi Academy of Agricultural Sciences department of Earth and Environmental engineering Columbia University department of Earth System science University of California State Key Laboratory of soil and Sustainable Agriculture Institute of Soil Science Chinese Academy of Sciences

Straw mulching allows for effective water storage in dryland wheat production. Finding a suitable straw mulching model that facilitates wheat growth was the objective of this study. A 2-year field experiment was conducted to investigate the effects of two straw mulching patterns （FM, full coverage within all the rows; HM, half coverage within alternate rows） and two mulching rates （4.5 and 9.0 t ha^-1） on soil moisture, soil temperature, grain yield, and water use efficiency （WUE） of winter wheat in northern China, with no mulching （M0） as the control. Results showed that mulching increased the soil water storage in all growth stages under high mulching rates, with a stronger effect in later growth stages. Water storage under the HM model was greater in later stages than under the FM model. soil water content of HM groups was higher than that of FM groups, especially in surface soil layers. Evapotranspiration decreased in mulched groups and was higher under high mulching rates. Aboveground biomass during each growth stage under the HM model was higher than that under M0 and FM models with the same mulched rate, leading to a relatively higher grain yield under the HM model. Mulching increased WUE, a trend that was more obvious under HM9.0 treatment. Warming effect of soil temperature under the HM pattern persisted longer than under the FM model with the same mulching rates. Accumulated soil temperature under mulched treatments increased, and the period of negative soil temperature decreased by 9-12 days under FM and by 10-20 days under HM. Thus, the HM pattern with 9.0 t ha^-1 mulching rate is beneficial for both soil temperature and water content management and can contribute to high yields and high WUE for wheat production in China.

作者： Hojat Ahmadi D.Y.Li Meisam Nouri Faculty of biosystems engineering University of TehranIran department of Chemical and Materials engineering University of AlbertaEdmontonCanada department of Materials engineering Tarbiat Modares UniversityTehranIran

TiNi alloy has a high resistance to wear and could be an excellent candidate for various tribological applications. But studies show that oxygen active elements can improve properties of some alloys, markedly. Yttrium is one of the oxygen active elements. In this paper, the effects of yttria addition on properties of TiNi have been studied via micro-indentation, hardness, wear and corrosive wear tests. It is demonstrated that by addition of yttria to 5%, TiNi alloy can own improved mechanical properties and resistance to wear and corrosive wear.

Studies on vibration characteristics of a pear using finite element method

引用

Journal of Zhejiang University-science B(Biomedicine & Biotechnology) 2006年第6期7卷 491-496页

作者： SONG Hui-zhi WANG Jun LI Yong-hui department of biosystems engineering Zhejiang University Hangzhou 310029 China

The variation of the vibration characteristics of a Huanghua pear was investigated using finite element simulations. A new image processing technique was used to obtain the unsymmetrical and un-spherical geometrical model of a pear. The vibra-tion characteristics of this type of pear with the correlation of its behavior with geometrical configurations and material charac-teristics were investigated using numerical modal analysis. The results showed that the eigenfrequency increased with the in-creasing pear Young’s modulus, while decreased with increasing pear density, and decreased with increasing pear volume. The results of this study provided foundation for further investigations of the physical characteristics of fruits and vegetables by using finite element simulations.
