This paper is concerned with the stochastic bounded consensus tracking problems of leader–follower multi-agent systems, where the control input of an agent can only use the information measured at the sampling instants from its neighborhood agents or a virtual leader with a time-varying...

This work is based on the dry sliding wear of NiCrBSi reinforced coating deposited on TA15 titanium alloy using the laser cladding technique, the parameters of which were such as to provide almost crack-free coatings with minimum dilution and very low porosity. SEM results indicated that a laser...

The ‘5.12’ earthquake in 2008 and the ‘8.13’ debris flow in 2010 brought huge losses of life and property to Qingping Township. Farmers’ livelihoods assets were also seriously affected and damaged. These led to a change in farmers’ livelihood styles and reduction in their income. A...

Base on 3 m×3 m grid in sloping cornfield with soil auger in Yingwugou Small Watershed of the Dan River Basin, a total of 39 sampling points were collected, and soil water content and nutrient content were measured in different soil depths. Meanwhile, the soil properties of different depth have...

Greening construction is an important part of the construction of ecological residential areas, but there exist some misunderstandings in greening construction of ecological residential districts at present. Based on the description of functions of green space in ecological residential areas,...

In this paper, we analyzed a fresh conception of the urban comprehensive carrying capacity in the context of ecosystem, economy and social dimensions. Based on the AHP methodology, the author constructs the urban comprehensive carrying capacity hierarchical structure model for the chosen ten...

We tested a wet extraction method for lipid extraction from <i>Euglena gracilis</i> water slurry at 0.51 MPa and 20 °C using liquefied dimethyl ether (DME). The yields, proximate analyses, elemental composition, and molecular weight distribution properties of the extracts from<i> E. gracilis</i> and the...

This study develops a sustainability assessment model for analysis and decision-making of the impact of China’s municipal solid waste management enhancement strategy options based on three waste treatment scenarios: landfill disposal, waste-to-energy incineration, and a combination of a...

Jiangsu is one of the most developed regions in China. Its’ urbanization rate increased to 61.9 % in 2011, faster than the whole country level (51.27 %). Exploring the influence of urbanization on energy consumption in Jiangsu may help find the relationship between energy consumption and...

The purpose of this paper is to use a center of gravity theory to study the spatial distribution and centers of gravity for the global energy supply and consumption and to determine how they have changed over time. In 2011, Middle East was the biggest oil producer and Asia Pacific was the...
