Aiming at the problem of limited energy of sensors in Wireless Sensor Network, based on the classic clustering routing algorithm LEACH, a distance-energy cluster structure algorithm considering both the distance and residual energy of nodes is presented, which improves the process of cluster head election and the process of data transmission. This protocol can successfully prolong the network’s...

This analysis of the future of the Australian Army takes as its rationale the proposition advanced by the military scholar Peter Paret, that the most important problem facing armed forces is never equipment, weapons acquisition or capability development, but the intellectual mastery of current and future military concepts. 1 In terms of intellectual mastery, the Australian Army—like its peers i...

Forty normal women had thrombin-stimulated platelet malondialdehyde (MDA) production measured during their menstrual cycle. Twenty women in this group were taking the combined oral contraceptive pill (OCP). Platelet MDA production was found to fall by 30% during normal menstruation and the week when the subjects were not taking a combined OCP, but it remained constant throughout the remainder o...

Bacteria-algae interaction in the epilimnion is modeled with the explicit consideration of carbon (energy) and phosphorus (nutrient). Global qualitative analysis and bifurcation diagrams of this model are presented. We hypothesize that there are three dynamical scenarios determined by the basic reproductive numbers of bacteria and algae. Effects of key environmental conditions are examined thro...

Different approaches to obtain sharp silicon tips with a variety of aspect ratios, for potential use in advanced microelectronics applications, were studied. Tips suited for atomic force microscopy and field emission arrays were formed by wet chemical etching of (100) and (111) single crystal silicon in KOH, TMAH and HNA etchant. Apex sharpening with thermal oxidising step resulted in tips with...
