A power control algorithm based on non-cooperative game for wireless sensor networks is presented to regulate the appropriate transmit power and satisfy the maximum requirement of network utility. In these networks, the appropriate transmission power is selected to improve the network topology, reduce the collisions, increase good put and confirm the(More)
In nutrient impoverished landscapes in southwest Australia, terrestrial litter appears to be important in phosphorus (P) turnover and in the gradual accumulation of P in wetland systems. Little is known about the fate of P leached from litter during the wet season and the associated effects of soil microclimate on microbial activity. The effects of(More)
Seasonal wetlands of the Swan Coastal Plain in southwestern Australia often dry in summer, refill during heavy winter rains, and are commonly surrounded by vegetated catchments. However, the linkage between catchment litter turnover and lake P dynamics is poorly understood. A transect from catchment uplands to the dry lakebed of Thomsons Lake was studied(More)
Forest thinning is expected to affect tree water use and carbon assimilation, but the related influence from climate variability is little known. Recent forest thinning in the Wungong catchment coincided with a record dry year following the thinning, which provides a rare opportunity to understand the climate influence on the thinning effect. A field(More)
Top-gated p-type field-effect transistors (FETs) have been fabricated in batch based on carbon nanotube (CNT) network thin films prepared from CNT solution and present high yield and highly uniform performance with small threshold voltage distribution with standard deviation of 34 mV. According to the property of FETs, various logical and arithmetical(More)
In this paper, we consider a molecular diffusion based communications link that can reliably transport data overthe-air. We show that the system can also reliably transport data across confined structural environments, especially in cases where conventional electromagnetic (EM) wave based systems may fail. In particular, this paper compares the performance(More)
Molecular communications between mobile nano-robots will likely yield bit transposition errors. In such a scenario, it is important to design and test a new family of appropriate forward-error-correction codes. In this paper, we first construct a proof-of-concept robot to demonstrate how transposition errors arise. We then review state-of-the-art research(More)
In this paper, we consider a molecular diffusion based communications link that conveys information on the macro-scale (several metres). The motivation is to apply molecular-based communications to challenging electromagnetic environments. We first derive a novel capture probability expression of a finite sized receiver. The paper then introduces the(More)
For the large-area fabrication of thin-film transistors (TFTs), a new conjugated polymer poly[9-(1-octylonoyl)-9H-carbazole-2,7-diyl] is developed to harvest ultrahigh-purity semiconducting single-walled carbon nanotubes. Combined with spectral and nanodevice characterization, the purity is estimated up to 99.9%. High density and uniform network formed by(More)
Nutrient leaching is a critical step in terrestrial litter turnover, and is potentially linked to nutrient cycling in downstream wetlands. Little is known about the leaching behaviour and P loading from terrestrial litter under conditions of winter rainfall in southwestern Australia. In this study, leaf litter of flooded gum (Eucalyptus rudis Endl.), a(More)
