A constrained cellular automata (CA) model based on 'grey cells' for the simulation of different types of urban forms and developments is developed within a raster GIS. Remote sensing and GIS are used to supply information on environmental constraints and locations of growth centers for the...

In this paper, we present a meta-heuristic base on improved shuffled frog leaping algorithm (SFLA) to tackle the multi-objective problem (MOP). The SFLA is suitable to solve the single objective problem. For the multi-objective problem, one main issue is that how to evaluate the quality of two...

Over the years, more attention has been focused on the implementation than on the preparation of the research budget in the agricultural institutes of China, resulting in the unscientific and unreasonable budgeting of research funds. The practical implementation of the research funds has also...

This paper introduces the computable general equilibrium (CGE) model into the comprehensive economic loss assessment due to rainstorm, using Beijing as an example. The article has constructed a regional storm disaster CGE model to measure the impacts made by rainstorm occurence on sectors and...

Industrialization of bio-energy relies on the supply of resources on a large scale. The theoretical biomass resources could reach 2.61–3.51billiontce (tons of coal equivalent)/a in China, while the available feedstock is about 440–640milliontce/a, however, among this only 1.5–2.5% has been...

In this paper, I extend the model in Coate and Loury (CL) (1993) to show how statistical discrimination by employers can help create gender wage gap for men and women with equal earning potentials. Given that employers do not perfectly observe a worker¡¯s skill type and partly rely on the...

This paper introduces the status quo of herdsman's settlement in Fuhai County of Xinjiang. As to the herdsman's settlement in this county, there are 5 models: centralized settlement, sporadic settlement, settlement along the river, striped settlement along hillside, flower-arrangement-style...

This study aims to evaluate the effects of elevated carbon dioxide (EC) on soybean growth in the water-deficient region of Huang-Huai-Hai Plain, China. A pot experiment involving two CO2 concentrations (ambient, 380.1±32.2μmolmol−1 and elevated, 740.6±45.4μmolmol−1) and two water levels...

Considerable research has been conducted on the topic of unidirectional evacuations from exits. However, few studies aim at simulating counter flow through a bottleneck with complex conflict. This paper proposes an agent-based model to investigate bidirectional flow evacuation. Pedestrian speed...

In-service teacher training aims to improve the supply of public education. A randomized experiment was conducted in Mexico to test whether teacher training could increase teacher efficiency in public secondary schools. After seven and a half months of exposure to a trained teacher, students...
