Cultivated land plays an important role in water and soil loss earthy/rocky mountainous regions northern China, however, its response to conservation measures rainfall characteristics are still not fully understood. In the present study, 85 erosive events 2011–2019 were grouped into three types, responses of runoff regimes on five cultivated plots with different slopes upstream catchment Miyun ...

Contour Crafting is an emerging technology that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. The Contour Crafting technology scales up automated additive fabrication from building small industrial parts to constructing buildings. Tool path planning and optimization for Contour Crafting benefit the technology by increasin...

Abstract Lanthanum zirconate (LZ) has emerged as a novel thermal barrier coating (TBC) material because of its higher temperature phase stability, and low sintering ability than the current standard yttria-stabilized zirconia (YSZ). In order to combine advantages, LZ YSZ feedstock powders are blended with predetermined weight ratios (50:50) composite coatings. The leading issue in developing us...

For hierarchical clustering, dendrograms provide convenient and powerful visualization. Although many visualization methods have been suggested for partitional clustering, their usefulness deteriorates quickly with increasing dimensionality of the data and/or they fail to represent structure between and within clusters simultaneously. In this paper we extend (dissimilarity) matrix shading with ...

Abstract Copolymers of [2-(acryloyloxy)ethyl]trimethylammonium chloride (AETAC) and acrylamide (AAm) (AETAC- co -AAm) are polyelectrolytes used as flocculants in wastewater purification. Diffusion-ordered two-dimensional NMR spectroscopy (DOSY) experiments for AETAC- -AAm samples with M w ranging from 1.9 to 3.9 million a polyacrylamide sample 1.3 were carried out pure D 2 O containing 0.1 or 1...
