The illumination of rough refraction is challenging due to the complex integrations of scattered lights from multiple directions. Prefiltered environment map is able to eliminate the comprehensive integrations, but the precomputation stage protects it from being adapted into dynamically varying environmental lighting. We propose a real-time method for rendering rough refraction, supporting dynamically...
The basic idea of H2-C mixture reduction reflexes using hydrogen as main reductant and carbon as main heat generator in iron bath smelt reduction reactors on purpose to cut down total energy consumption and CO2 emission, protect the environment and take advantage of the new energy source. First of all, the calculation of mass and energy balance is very important for the smelt production, optimization...
Many privacy-protecting electronic payment systems have been proposed to realize the revocable anonymity among users. In this paper, by organizing all users into a group, we present an anonymity revocable electronic prosecution report system. The report system is efficient and the user's privacy will not be compromised in normal cases. However, when defamation was detected, the anonymity can be removed...
