The integration of Geographic Information Systems (GIS) and On-Line Analytical Processing (OLAP), denoted SOLAP, is aimed at exploring and analyzing spatial data. In real-world SOLAP applications, spatial and non-spatial data are subject to changes. In this paper we present a temporal query language for SOLAP, called TPiet-QL, supporting so-called discrete changes (for example, in land use or c...

Complex system evaluation lies in the core position of system engineering theory and methodology and is also a research hotspot and difficulty in system engineering theory and practice research. The paper, taking performance evaluation of integrates with agriculture base and supermarket for example, advances an evaluation indicator system and a fuzzy comprehensive evaluation algorithm. Firstly,...

The degraded ecosystem in the Loess Plateau region of China is very vulnerable, which has a great impact on regional sustainable development. Taking the Loess Plateau of Yan’an, Shaanxi province, China, as the study area, this study quantitatively evaluated conditions of the ecological environment. Based on natural factors, environmental factors, and socio-economic factors of Yan’an in 1997, 20...

Abstract Geotechnical Seismic Isolation (GSI) can be defined as a new category of seismic isolation techniques that involve the dynamic interaction between structural system and geo-materials. Whilst mechanism various GSI systems their performance have already been demonstrated through different research methods, there is missing link fundamental engineering practice. This paper aims to initiat...
