In this study, wind characteristics and wind energy potential of Armidale, which is a regional rural city (the highest in Australia) in the Northern Tablelands of New South Wales (NSW) are examined and analysed utilizing mean daily wind velocity observations collected during the period 1994 to...

This paper discusses and determines the optimization process of sizing a hybrid renewable energy system designed for urban residential buildings in Armidale NSW, Australia. The considered renewable energy system comprises of solar photovoltaic (PV) system and wind turbines as small scale or...

In this study, a handy quick estimate of expected power and cost of micro-scale generation wind turbines is generated for the purpose of simplifying and facilitating the deal of non-specialists with the sophisticated technicalities of micro-scale generation wind turbines technologies and...

Intermittency is an apparent characteristic of some renewable energy sources and this specifically applies to solar, wind and tidal renewable sources. Thus, battery storage is a real important element of any photo voltaic (PV) energy generation systems. As well, sizing of battery storage plays a...

In this study, a general overview of energy and renewable energy sources available in Australia was introduced, household’s electricity situation in Australia was presented, and focus wind energy was conducted. A theoretical methodology for quantification and costing of selected micro wind...

The proliferation of algorithmic high-frequency trading in financial markets has also led to an increase in new types of fraudulent activity. Since the flash-crash of 2010 first brought it to popular prominence, layering or spoofing fraud has become a major concern for financial regulators...

It is well known that in a vector autoregressive (VAR) model Granger non-causality is characterized by a set of restrictions on the VAR coefficients. This characterization has been derived under the assumption of non-singularity of the covariance matrix of the innovations. This note shows that...

The method of instrumental variables (IV) and the generalized method of moments (GMM), and their applications to the estimation of errors-in-variables and simultaneous equations models in econometrics, require data on a sufficient number of instrumental variables that are both exogenous and...

This paper focuses on finding starting-values for the estimation of Vector STAR models. Based on a Monte Carlo study, different procedures are evaluated. Their performance is assessed with respect to model fit and computational effort. I employ (i) grid search algorithms and (ii) heuristic...

This paper proposes plug-in bandwidth selection for kernel density estimation with discrete data via minimization of mean summed square error. Simulation results show that the plug-in bandwidths perform well, relative to cross-validated bandwidths, in non-uniform designs. We further find that...
