This paper aims to provide guidance to ecologists with limited experience in spatial analysis to help in their choice of techniques. It uses examples to compare methods of spatial analysis for ecological field data. A taxonomy of different data types is presented, including pointand area-referenced data, with and without attributes. Spatially and non-spatially explicit data are distinguished. T...
AIM The spatial structure of a population can strongly influence the dynamics of infectious diseases, yet rarely is the underlying structure quantified. A case in point is plague, an infectious zoonotic disease caused by the bacterium Yersinia pestis. Plague dynamics within the Central Asian desert plague focus have been extensively modelled in recent years, but always with strong uniformity as...
This article continues and completes our previous work [14] J. Phys. Commun. 2 (2018) 025007. First of all, we present two methods quantization associated with a linear connection given on differentiable manifold, one them being the presented in [14]. The allow quantize functions that come from covariant tensor fields. equivalence both is demonstrated as consequence remarkable property Riemanni...
The prediction of nodal electricity price (NEP) is a primary step to be done before the bidding process starts in actual market environment. NEP plays significant role for efficient working electrical system. follows common trend as during peak hours when load high will also similarly off-peak-load times lower and all node. Thus, accurate forecasting can help generation companies more proactive...
In this paper, a generalized expression for the flow field in axisymmetric extrusion process is suggested to be valid for any dies and the boundary shapes of the plastic deformation zone. The general power terms are derived and the extrusion force is calculated by applying upper bound technique for a streamlined die shape and exponential functions for shear boundaries. It is shown that assuming...
