Construction project is not a standalone engineering maneuver.It is closely linked to the well-being of local communities in concern.The city renovation in Beijing down center for Olympic 2008 transformed many antique architecture and regional landscape.It gave a world-recognized achievement in China s modem development and manifested a major milestone in China's economic development.In the course of metro construction projects,there are substantial interwoven municipal structures influencing the success of the projects,which including,but the least,all underground cables and ducts,sewage system,the power consumption of construction works,traffic diversion,air pollution,expatriate business activities and social security.There are many US and UK project insurance companies moving into Asia Pacific.They are doing re-insurance business on major construction guarantee,such as machinery damage,project on-time,power consumption,claims from contractors and communities.Environmental information,such as water quality,indoor and outdoor air quality,people inflow and lift waiting time play deterministic roles in construction's fit-touse.Big Data is a contemporary buzzword since 2013,and the key competence is to provide real time response to heuristic syndrome in order to make short-term prediction.This paper attempts to develop a conceptual model in big data for construction 展开更多

HELICON800MKII是DALI当中最具代表性的型号之一。作为DALI的中端产品,HELICON800MKII不仅继承了旗舰Euphiona系列的很多技术,而且价格相对便宜,同时又能应付中型或更大的家居环境,可满足大部分用家的需要。HELICON800MKII是从HELICON800改进而来,主要在低音单元上使用了DALI最新开发的磁路,此磁路相比起之前的磁路能提供更大的磁通量,不仅扩展了低频下限,提高提高单元的效率,同时让阻抗变化更小,从而让功放的推动更轻松。在分频器上,HELICON800MKIIA选用了全新的组件,而且连接线也改用品质更好的线材,让信号在传输过程中的衰减更少,可让音箱重播出更多的细节。 展开更多
