Balcony greening have the ecological effects on reducing temperature and increasing humidity,purifying air and beautifying environment etc. Combined the experiments with simulation, by figuring out the potency of reducing temperature and increasing humidity of balcony greening on indoor thermal environment, the correctness of the model was verified. The results show that the temperature of the greening...
The limit equilibrium method is usually used in stability analysis of reinforced roadbed. It considers the function of reinforcing material as equivalent tension and neglects Interaction betweens oil and reinforcing material. Based on the roadbed engineering construction of phase III engineering in Beijing-Chengde Highway, a grid-soil contact element has been constructed to research the application...
The conventional cooperative protocols have to face some problems in practical broadcast and multicast systems because feedback channel is unavailable. An adaptive cooperative relay protocol, which can be adopted in future broadcast systems, is proposed in this paper. The outage probability performance of this protocol is analyzed over Nakagami-m fading channel, and the asymptotic expression of outage...
The signification of the exergy transfer phenomenological equation for multi-potential fields is introduced, and the concept of field influence factor of exergy transfer resistance is defined. Based on the analysis of the field structure for the thermal driving process, the exergy transfer analysis target is advanced, including the driving work (exergy), driving power (exergy flux), driving resistance...
The hot air recirculation phenomenon observed in direct air- cooled system is numerical simulated and the causes of the hot air recirculation and its influence on air-cooled units are qualitatively analyzed with the help of computational fluid dynamics (CFD) software. The results indicate that the hot air recirculation is a common trouble in the air-cooled power units. It is provoked by the arrangement...
Nanoscale double-gate n-MOSFETs with silicon and III-V (GaAs and InAs) channels are studied using numerical simulation. The device structures are based on the ITRS 14 nm node (year 2020), and are simulated using the program nanoMOS, which utilizes the NEGF technique for treating ballistic electron transport in the channel. The effective masses used are obtained by extraction from the full band structure...
