The history of geophysics in Australia began with the first European explorers, who were concerned with the measurement of basic geophysical quantities, such as the Earth’s gravitational and magnetic fields (Day, 1966). By the first half of the twentieth century, Australia had been recognised as a possible happy-hunting ground for the new methods of exploration geophysics, as witness the accoun...

Abstract. This study proposes two methodologies for improving the accuracy of wind turbine load assessment under wake conditions by combining nacelle-mounted lidar measurements with field reconstruction techniques. The first approach consists incorporating flow field, obtained from nacelle lidars, into random, homogeneous Gaussian turbulence fields generated using Mann spectral tensor model. se...

Aims. The realization of an experimental set-up for the quantitative and objective description of drawing using optoelectronic systems, which could be used when a quantification of the realization of specific drawing tests is required. Methods. Healthy subjects, subjects with Parkinson's Disease and subjects with Parkinson's Disease and Dementia were evaluated by the Mini Mental Scale Evaluatio...

We introduce a flexible optimization framework for nuclear norm minimization of matrices with linear structure, including Hankel, Toeplitz and moment structures, and catalog applications from diverse fields under this framework. We discuss various first-order methods for solving the resulting optimization problem, including alternating direction methods of multipliers, proximal point algorithms...

Hyper-crosslinked (HCL) polystyrenes show outstanding properties, such as high specific surface area and adsorption capability. Several researches have been recently focused on tailoring their performance for specific applications, such as gas adsorption and separation, energy storage, air and water purification processes, and catalysis. In this review, main strategies for the realization of HC...

Realization of half-metallicity in low dimensional materials is a fundamental challenge for nano spintronics, which is a critical component for next-generation information technology. Using the method of generalized Bloch theorem, we show that an in-plane bending can induce inhomogeneous strains, which in turn lead to spin-splitting in zigzag graphene nanoribbons and results in the highly desir...

We construct a realization of the elliptic quantum algebra Uq,p(ŝlN) for any given level k in terms of free boson fields and their twisted partners. It can be considered as the elliptic deformation of the Wakimoto realization of the quantum affine algebra Uq(ŝlN). We also construct a family of screening currents, which commute with the currents of Uq,p(ŝlN) up to total q-differences. And we giv...

A simple and fast algorithm for generating two correlated stochastic twodimensional (2D) cloud fields is described. The algorithm is illustrated with two broken cumulus cloud fields: cloud optical depth and cloud top height retrieved from Moderate Resolution Imaging Spectrometer (MODIS). Only two 2D fields are required as an input. The algorithm output is statistical realizations of these two f...

Organizations are increasingly employing business process modelling techniques in an attempt to visualise their processes and highlight the improvements that need to be made. However, despite the plethora of modelling techniques available, the main focus has typically been the graphical depiction of a process. As of yet little consideration has been given into how a process can be presented in ...

We show that the spatial correlation function of a flux-limited sample of Xray selected clusters of galaxies will exhibit a correlation scale that is smaller than the correlation scale of a volume-limited, richness-limited sample of comparable apparent spatial density. The flux-limited sample contains clusters of different richnesses at different distances: poor groups are found nearby and rich...
