This experimental study simulates key economic and psychological factors that affect producer contributions to generic advertising. The results suggests that producer referendum play a ...
In this paper we describe the modelling of producer/consumer constraints with the CHIP system. Producer/consumer constraints arise in scheduling problems with consumable resources like raw materials or money, in particular for batch based processing. The constraint assures that at each time point enough consumable resources are available. The modelling with CHIP uses the cumulative constraint t...
Consumer and resource control of diversity in plant communities have long been treated as alternative hypotheses. However, experimental and theoretical evidence suggests that herbivores and nutrient resources interactively regulate the number and relative abundance of coexisting plant species. Experiments have yielded divergent and often contradictory responses within and among ecosystems, and ...
Abstract—Producer gas is a biomass derived gaseous fuel which is extensively used in internal combustion engines for power generation application. Unlike the conventional hydrocarbon fuels (Gasoline and Natural gas), the combustion properties of producer gas fuel are much different. Therefore, setting of optimal spark time for efficient engine operation is required. Owing to the fluctuating ten...
