In modeling spatial processes, a second-order stationarity assumption is often made. However, for data observed on vast domain, the covariance function varies over space, leading to heterogeneous dependence structure, therefore requiring nonstationary modeling. Spatial deformation one of main methods assuming process has stationary counterpart in deformed space. The estimation poses severe chal...
This paper focuses on an overview of kernel density estimation especially for what concerns the choice of bandwidth and intensity parameters according to local conditions. A case study inherent seismic risk analysis of the old town centre of Potenza hilltop town has been discussed, with particular attention to the evaluation of the possible local amplifying factors. This first integrated applic...
when we return to the concept of poetry and the age-old discussion about the uselessness or the usefulness of the poets to the private and public state of human beings, originating from plato and aristotles views about poets respectively, there emerges the question of the role of poetry in human beings lives. in the same manner, with the advance of technology and the daily progress and improvem...
Mineral resource estimation involves the determination of grade and tonnage a mineral deposit based on its geological characteristics using various methods. Conventional methods, such as geometric geostatistical techniques, remain most widely used methods for estimation. However, recent advances in computer algorithms have allowed researchers to explore potential machine learning techniques Thi...
the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
Determination of facilities, such as factories or warehouses, location and availability conditions is one of the important and strategic decisions for an organization to make. Transportation costs that form a major part of goods price are dependent to this decision making. There are verity of methods have been presented to achieve the optimal locations of these facilities which are generally de...
Estimation of ore reserves is one of the most critical aspects of mining geology. The accurate assessment of the tonnage and grade of run of mine may be the difference between a healthy profitable operation and an expensive early mine closure. The first step in ore reserve estimation is to determine the boundary of ore body or ore/waste contacts. This paper presents a specific mining applicatio...
The work deals with development and application of Radial basis functions neural networks (RBFNN) for spatial predictions. Geostatistical tools for spatial correlation analysis (variography) are used to qualify and quantify the estimation results. Geostatistical analysis is performed on the residuals obtained at the training and test sample locations. Variogram of residuals explores spatial cor...
