Based on the survey data of Jiaozhou Bay waters in May, September and October 1993, this paper studies surface horizontal distribution PHC content waters. According to definition, model classification Yang Dongfang homogeneity theory matter proposed by author, calculation results show that Bay, non-homogeneous column was 46.86μg/L, 8.15%. At time, had non-homogeneity; September, 6.53μg/L, homog...

An autonomous system for field land surface temperature (LST) measurements taken at different observation angles was developed to be deployed easily at any conventional meteorological tower station. The system permits ground-truth data to be acquired on a continuous basis, and angularly scans land and sky hemispheres with a single thermal-infrared (TIR) radiometer. This paper describes the auto...

abstract the objective of the present study is to assess the performance of 18 irrigation districts from ten countries in the world using the benchmarking method and data mining analysis (cluster analysis). irrigation networks of dez, sefidrood, tajan and voshmgir from iran have been compared with 14 irrigation districts from nine other countries. the k- means algorithm was used to analyze the ...

Theoretical considerations and empirical evidence indicate a linear relationship between the land surface temperature (Ts) and the corresponding evapotranspiration (ET) rate under spatially constant wind and net energy conditions at a homogeneous vegetated surface. Such a relationship lies at the core of the popular surface energy balance algorithm (SEBAL); the satellite-based energy balance ap...

Syrtis Major is an old, low relief volcanic plateau near the equatorial regions of Mars. It is a persistent low-albedo feature on the planet and is thought o contain a high abundance of exposed bedrock and/or locally derived surface material and debris. Spatially resolved variations in surface spectral properties, and therefore composition, are investigated with data from the Imaging Spectromet...

This paper presents a family of Runge{Kutta type integration schemes of arbitrarily high order for di erential equations evolving on manifolds. We prove that any classical Runge{Kutta method can be turned into an invariant method of the same order on a general homogeneous manifold, and present a family of algorithms that are relatively simple to implement.

The concept of \shape spectrum" of an object view is introduced for constructing view aspects of free-form objects. The shape spectrum captures the shape characteristics of an object by aggregating the areas of the surfaces of the object at each value of the shape index. We derive a novel view representation based on shape spectral features and propose a general and powerful technique for organ...

We demonstrate the use of fluorescence microscopy as a tool for mapping the spatial distribution of fluid flow and electrochemical reactions in an operating aqueous quinone flow cell. 9,10anthraquinone-2,7-disulfonic acid (AQDS) is a reversibly redox active molecule with a reduced form (H2AQDS) that fluoresces when excited by UV light. Visualization of AQDS/H2AQDS within commercial porous carbo...

Let X be a real algebraic variety (resp. nonsingular variety) and let Y homogeneous space for some linear group. We prove that continuous C ∞ ) map f : → can approximated by regular maps in the 0 topology if only it is homotopic to map. Taking = S p , unit -dimensional sphere, we obtain solutions of several problems have been open since 1980's which concern approximation with values spheres. Th...

We generalize Cartan's logarithmic derivative of a smooth map from manifold into Lie group $G$ to maps homogeneous space $M=G/H$, and determine the global monodromy obstruction reconstructing such infinitesimal data. The embedding submanifold $\Sigma \subset M$ becomes an invariant $ under symmetries "Klein geometry" $M$ whose analysis is taken up in [SIGMA 14 (2018), 062, 36 pages, arXiv:1703....
