BACKGROUND Climate change is anticipated to affect human health by changing the distribution of known risk factors. Heat waves have had debilitating effects on human mortality, and global climate models predict an increase in the frequency and severity of heat waves. The extent to which climate change will harm human health through changes in the distribution of heat waves and the sources of un...

The paper introduces the intelligent neural network to make forecast for the climate index in the real estate market. At the same time, deeply mine the practical use of intelligent system of neural network, thus, abundant chaos phenomenons are obtained in the hidden nodes by numerical simulation. The bifurcation diagram and chaotic attractors are drawn from two dimensional chaotic neurons to se...
