The location of rescue centers is a key problem in optimal resource allocation and logistics in emergency response.
      
Dynamic multicast traffic grooming in wavelength division multiplexing (WDM) networks was analyzed to minimize networkwide costs and to increase the network resource utilization.
      
A network model was developed for dynamic multicast traffic grooming with resource constraints and an algorithm that can provide quality of service (QoS) was proposed.
      
The simulation support platform architecture consists of the management layer, the resource layer, the communication layer, the application layer and the infrastructure layer.
      
The best way is to design and realize the M>amp;amp;S collaborative environment for simulation support platform in the resource-communication-application three-dimension space.
      
Simulation results show that, compared with other bandwidth allocation schemes, the proposed scheme offers very low call dropping probability for real-time connections while, at the same time, keeping resource utilization high.
      
Through local probing, the algorithm accurately estimated the resource status of the access network.
      
It is suitable for forest resource information updating and forecasting for a large region, e.g., a province.
      
To enrich resource of species, 105 arbor species (25 genera, 15 families) were introduced to the hilly and gully areas on Loess Plateau.
      
In order to provide a scientific foundation for the protection of the Metasequoia resource, it has become necessary to analyze the changes in the original, natural Metasequoia mother trees (ONMMT) and their environment from 1948 to 2003.
      
Altitudinal gradient incorporates multiple resource gradients, which vary continuously in different fashions.
      
The physicochemical properties of soil changed with the change of space and resource availability in gaps.
      
Using principles of ecosystem health quantitative assessment and diagnosis index selection, 17 factors were considered from three aspects: resource and environmental capacity, social and economic impact, and ecological services.
      
Therefore, it is very necessary to improve forest productivity, resource use efficiency and management of forest ecosystems scientifically.
      
The whole system is set up on the base of engineering database technology, integrating Product Data Management (PDM), Enterprise Resource Planning (ERP) etc.
      
Cellulose is a kind of renewable resource that is abundant in nature.
      
Seasonal dynamics of fine root biomass, root length density, specific root length, and soil resource availability in a Larix gme
      
In temperate forest ecosystems, seasonal changes of soil resource availability will alter the pattern of carbon allocation to belowground.
      
Studying seasonal changes of fine root biomass, RLD, and SRL associated with soil resource availability will help us understand the mechanistic controls of carbon to fine root longevity and turnover.
      
Multiple regression analysis showed that variation in soil resource availability could explain 71-73% of the seasonal variation of RLD and SRL and 58% of the variation in fine root biomass.
