Energy simulation models are developed with EnergyPlus for two office buildings in a R&D center in Shanghai, China to evaluate the energy cost savings of green building design options compared with the baseline building. As a R&D center of an international IT corporation, there are data centers in the two buildings, which make them different from typical(More)
Optimizing the operations of a HVAC system in response to the dynamic loads and varying weather conditions throughout a year can result in substantial energy savings. However, the problems related to HVAC system optimization are always discrete, non-linear and highly constrained. So, a simulation-based optimization approach for a HVAC system is proposed. To(More)
It is very difficult to restore natural geometry of the actual image from degraded observation. In this paper, to deal with approximation error and the turbulence casued by proximal splitting scheme, a generalized proximal conjugate gradient framework is proposed. To trade off approximate accuracy and computational complexity, an approximate solution is(More)
The application of Multi-function Road Surface (MRS) in the anti-skid maintenance of steel deck of Zhongshan Guangming Bridge was introduced and the mechanical properties of MRS binder and the high temperature stability, water stability, adhesive property of MRS pavement were comprehensively studied. The results indicated that MRS binder had excellent bond(More)
In this paper, we present evidence that firms with concentrated ownership manage earnings when their large shareholders have an incentive to do so. The large shareholders of Chinese public firms often pledge their shares for loans. Before the split share reform in 2006, loan terms were based on the book value of the firm. Since then, the share price has(More)
Epidemiological studies have revealed the association between increased risk of bladder cancer and chronic arsenic exposure. Here, we explored biological effects of arsenic in T24. Microarray analysis was applied to analyze mRNA in T24 following 0, 2 or 5 μM sodium arsenite (As) exposure for 72 hours. Long term (up to 140 days) low-dose (200 nM) and(More)
