The Earth’s surface is uneven, and conventional area calculation methods are based on the assumption that the projection plane area can be obtained without considering the actual undulation of the Earth’s surface and by simplifying the Earth’s shape to be a standard ellipsoid. However, the true surface area is important for investigating and evaluating land resources. In this study, the authors...

Cassava has become a ‘must have’ crop for many Cambodian smallholders; yet, the market is volatile and yields are uneven. Drawing on long-term fieldwork in Kampong Thom Ratanakiri provinces, we analyse how farmers cope with volatility. We argue that multiple pathways have emerged: some ceased producing cassava; expanded production; while most engage ‘ambivalent repeasantisation’, striving to ga...

The Passage mechanism introduced in this paper provides an easy and intuitive way to transport various types of digital objects by using also normal physical objects without any special identification tags. The current implementation of the Passage mechanism utilizes electronic scales and contact-free identification devices and thus allows for identification of arbitrary physical objects as wel...

A survival model for shortleaf pine (Pinus echinata Mill.) trees growing in uneven-aged stands was developed using data from permanently established plots maintained by an industrial forestry company in western Arkansas. Parameters were fitted to a logistic regression model with a Bernoulli dependent variable in which ‘1” represented individual tree survival and “0” represented individual tree ...

A recent experiment showed that, contrary to theoretical predictions, beyond a cutoff point grinding coffee more finely results in lower extraction. One potential explanation for this is that fine promotes non-uniform extraction the bed. We investigate possibility could occur due interaction between dissolution and flow promoting uneven low dimensional model which there are two possible pathway...

Land-use/land-cover change and climate have changed the spatial–temporal distribution of water resources. The Huai River Basin shows spatial temporal changes from 1960 to 2016 land-use/land-cover 1995 2014. Thus, this study aims investigate change, land use, vegetation evolution in Upper Basin. Mann–Kendall test (MK), Innovative Trend Analysis Method (ITAM), Sen’s slope estimator were used dete...

Considering that the development of urbanization cannot be separated from application landscape pattern evolution, in order to improve level ecocity, a modeling analysis ecological urban evolution based on multisource remote sensing data is proposed. Taking ecotype city as research object, images are screened by using and nonremote basic data. CA-Markov model constructed analyzed. The experimen...
