We investigate the power-law scaling behaviors of returns for a financial price process which is developed by the voter interacting dynamic system in comparison with the real financial market index (Shanghai Composite Index). The voter system is a continuous time Markov process, which originally...

Spectral clustering uses eigenvectors of the Laplacian of the similarity matrix. It is convenient to solve binary clustering problems. When applied to multi-way clustering, either the binary spectral clustering is recursively applied or an embedding to spectral space is done and some other...

Land subsidence, a major geological hazard in Tianjin, has caused serious losses. In this research, we established a numerical model to predict potential land subsidence caused by groundwater overdraft in the next decades. The model set three groundwater extraction scenarios, corresponding to...

Based on daily, monthly, seasonal and annual precipitation, monthly duration and flood-affected area data from 1954 to 2007, we examined the absolute and relative change trends of rainfall and their effects on hazard intensity in Wenzhou city, China. The long-term trend of precipitation was...

Huangpu River floodplain is historically vulnerable to flooding due to its location in the path of tropical cyclones, low elevation, relatively flat topography, rapid changes in sea level and fast rate of land subsidence due to urbanization. This paper presents a scenario-based study that...

Based on the analysis and calculation of the hazard intensity of typhoon rainstorms and floods as well as the vulnerability of flood receptors and the possibility of great losses, risk scenarios are proposed and presented in Wenzhou City, Zhejiang Province, China, using the Pearson-III model and...

A series of empirical studies involving typhoon rainstorm and flood risk scenario analysis were carried out on a medium spatial scale, covering Pingyang County. Considering a rainstorm/water-logging conversion process, active flooding submergence and per unit area values (million yuan/km<Superscript>2</Superscript>), two...</superscript>

Shanghai is a low-lying city (3–4 m elevation) surrounded on three sides by the East China Sea, the Yangtze River Estuary, and Hangzhou Bay. With a history of rapid changes in sea level and land subsidence, Shanghai is often plagued by extreme typhoon storm surges. The interaction of sea...

This paper presents a scenario-based study that investigates the interaction between sea-level rise and land subsidence on the storm tides induced fluvial flooding in the Huangpu river floodplain. Two projections of relative sea level rise (RSLR) were presented (2030 and 2050). Water level...

This paper examines the impact of political uncertainty (caused by the civil uprisings in the Arab World i.e., “Arab Spring”) on the volatility of major stock markets in the MENA region. Our main findings are as follows. First, by distinguishing between conventional and Islamic stock market...
