Dark Energy and Fate of the Universe
, 2012 We explore the ultimate fate of the Universe by using a divergence-free parametrization for dark energy $w(z)=w_0+w_a({\ln (2+z)\over 1+z}-\ln2)$. Unlike the CPL parametrization, this parametrization has well behaved, bounded behavior for both high ...

Semi-empirical forecast modelling of rip-current and shore-break wave hazards [PDF]
Natural Hazards and Earth System SciencesSandy beaches are highly attractive but also potentially dangerous environments for those entering the water as they can be exposed to physical hazards in the surf zone.

, 2012 We present an holographic brane-world model of the Dvali-Gabadadze-Porrati (DGP) scenario with and without a Gauss-Bonnet term (GB) in the bulk. We show that an holographic dark energy component with the Ricci scale as the infra-red cutoff can describe ...

, 2015 In this paper, we consider the problem of compressive sensing (CS) recovery with a prior support and the prior support quality information available. Different from classical works which exploit prior support blindly, we shall propose novel CS recovery ...

Tradeoff between Smoother and Sooner "Little Rip"
, 2013 There exists dark energy models that predict the occurrence of "little rip". At the point of little rip the Hubble rate and its cosmic time derivative approach infinity, which is quite similar to the big rip singularity except that the former happens at ...

Vertical Distribution of Rip Currents Generated by Intersecting Waves in a Sandbar–Groin Systems
Journal of Marine Science and EngineeringTo analyze the impacts of groins, sandbars, and channels on the three-dimensional features of rip currents, we conducted experimental investigations on the vertical distribution of rip currents under intersecting waves along barred beaches with channels.

The use of imaging systems to monitor shoreline dynamics [PDF]
, 2005 The development of imaging systems is nowadays established as one of the most powerful and reliable tools for monitoring beach morphodynamics. Two different techniques for shoreline detection are presented here and, in one case, applied to the study of ...

Rip Currents Have Least Friction
Natural Science, 2020 Surface gravity waves continually come to the beach but rarely go back to sea. They bring excess mass to shore which must be returned offshore. Rip currents do that job because there is less overall friction in the nearshore region than there is in the only other imagined circulation, a two-layer scheme, which has in fact never been seen.

Australian and International Journal of Rural Education, 2012 Monash University (Gippsland campus) is situated in Churchill, Latrobe Valley, located in central Gippsland, eastern Victoria. A large percentage of the Gippsland region comprises of a socio-economically disadvantaged population (Figure 1). In Semester One, 2011 as part of the Bachelor of Primary Education course at Monash, it was decided that a ...
