It can make the application within distributed heterogeneous environments reusable, portable and interoperable. The architecture of CORBA-based discrete event simulation systems is presented and the interface of distributed simulation objects (DSO) is defined in this paper after the DSO is identified and the synchronization mechanism among DSO is discussed.展开更多

The rapid performance detection to existing subgrades is important to their reasonable evaluation and maximized utilization. Based on five kinds of soils taken from an existing highway in southern China, three commonly detecting methods were used to determine their moisture contents, compaction degrees and resilient moduli. The results showed that the measured moisture contents were greater than the design value, and the compaction degrees decreased sharply compared to the original ones. The moisture and heat exchange produced a decrease in the resilient modulus of plate loading test(PLT) from the standard 60 MPa down to 40 MPa. Afterwards, the portable falling weight deflectometer(PFWD) and dynamic cone penetrometer(DCP) were used to evaluate the subgrade performances. The measured PFWD moduli and the DCP penetration rates were correlated with the resilient moduli of PLT, deflections of the Beckman beam test, compaction degrees and moisture contents. The correlation analysis indicates that both of two methods are suitable in rapid detecting subgrade performances, but PFWD method is more recommended for it has higher accuracy and efficiency.展开更多

Between fossil and solar eras, low carbon natural gas and clean coal become the most crucial intermediate alternatives as energy source and feedstock to produce chemicals. In meantime, lignocellulosic biomass will play the role as fuel or as raw material, espe-cially for the future decades. This is of ultimate importance for the countries with increased demands for energy in a portable form and for synthetic materials, such as China.New catalytic materials are at the heart in the processes (existing and innovative) to converting natural gas or coal, the non-portable or non-pumpable energy carriers, to liquid form, and to upgrading less valuable to more value-added chemicals for a particu-lar market requirement. In many instances, innovation of a new catalytic material makes a new process from dream to reality, and in the other cases, the need for a new process catalyzes the research for a new catalytic material. The process and material ("chickens and eggs") interplay propels the recent advances in hydrogen fuel, GTL,CTL,CTC, SNG and BTL technologies. In this growing market, Sud-Chemie has not only strengthened its market presence, but also consolidated its position as the worldwide technology and market leader through innovative R&D work and broad cooperation with partners. Siid-Chemie provides the full portfolio of cat-alytic materials in the new chemical processes, such as ShiftMax , ActiSorb , AmoMax , MegaMax, DME-1, FAMax, and MTProp-1. Sud-Chemie commits to provide the best performing tailored catalytic materials to the matching processes.展开更多
