The effects of tree species on the dynamics of nutrient transformations during leaf-litter decomposition are not well understood in tropical rain forests. To examine differences in the dynamics of C, nutrients, and organic constituents during decomposition among tree species, the leaf-litter decomposition of 15 trees was assessed using a litter-bag method(More)
In a lowland tropical rain forest in Sarawak, leaf-litter decomposition and the initial litter chemistry of 15 tree species were studied. During 13 months of field experiment, weight loss of litter samples was between 44% and 91%, and calculated decomposition rate constants (k) ranged from 0.38 to 2.36 year−1. The initial litter chemistry also varied widely(More)
Sweep coverage is one of the important and recent issue for network monitoring in wireless sensor network (WSN). Sweep coverage is efficiently applicable where periodic monitoring is sufficient than continuous monitoring. Interference minimization is another main objective of topology control problem in wireless sensor network. Reducing interference in turn(More)
Given a set of sensors, the strong minimum energy topology (SMET) problem is to assign transmission range to each sensor node so that the sum of the transmission range for all the sensor is minimum subject to the constraint that the network is strongly connected (there is a directed path between every pair of nodes in the Network). This problem is known to(More)
