One of the most important issues in all stages of mining study is capital cost estimation. Determination of capital expenditure is a challenging issue for mine designers. In recent decade, quite a few number of studies have focused on proposing estimation models to predict mining capital cost. However, these efforts have not achieved to a predictor model with reliable range of error. Both of ov...

This report addresses the problem of computation of the output of the Weighted Myriad Filter. Weighted Myriad Filters form a large and important class of nonlinear lters that includes linear FIR lters, with several potential applications in robust signal processing and communications in impulsive non-Gaussian environments. Just as the weighted mean and the weighted median are optimized for the ...

Defect engineering is used to augment the porosity of MIL-100. Incorporation defects leads structural collapse and ultimately causes amorphisation. Pair distribution function analysis reveals a stepwise hierarchical structure.

In this note we consider the problem of, given a sample, selecting the number of bins in a histogram. A loss function is introduced which reflects the idea that smooth distributions should have fewer bins than rough distributions. A stepwise Bayes rule, based on the Bayesian bootstrap, is found and is shown to be admissible. Some simulation results are presented to show how the rule works in pr...

ObjectivesThis cost-effectiveness analysis (CEA) of 4CMenB infant vaccination in England comprehensively considers the broad burden serogroup B invasive meningococcal disease (MenB IMD), which has not been considered, or was only partially considered previous CEAs.MethodsA review MenB CEAs conducted to identify aspects evaluation costs and health outcomes IMD. To inform model structure comprehe...

The Energy Storage System (ESS) is an expensive component of an E-bike. The idea of Hybrid Energy Storage System (HESS), a combination between battery and Ultra-Capacitor (UC), can moderate the cost of E-bike ESS. In this paper, a cost function is developed to use for optimal sizing of a HESS. This cost function is consisted of the HESS (battery, UC and DC/DC converter) cost and the cost of bat...

This paper applies an evolutionary algorithm, the particle swarm optimization (PSO), to design the optimum open channel section. Depth, channel side slope and bottom width are considered as the variables for rectangular, triangular and trapezoidal channels, respectively. The objective function is minimizing the construction cost of the channel section. MATLAB software is used for programming an...

liberalization of energy price increases costs of agricultural inputs and costs of agricultural production. all these changes may affect the overall competitiveness of domestic products with similar foreign products. as a result of that, total cost of agricultural products are increased and profitability are decreased. in this paper, energy consumption for producing corn were calculated using c...

We analyze the optimal investment strategy of a firm that can complete a project either in one stage at a single freely chosen time point or in incremental steps at distinct time points. The presence of economies of scale gives rise to the following trade-off: lumpy investment has a lower total cost, but stepwise investment gives more flexibility by letting the firm choose the timing individual...

This paper presents local solidification of metal powder, irradiated by localized microwaves, as potential means for stepwise additive formation of 3D structures. Experimental results of metal powder solidified locally by microwaves are presented in forms of spheres and rods in a 1-10 mm range. The feasibility of extending solid structures by adding powder batches and solidifying them locally, ...
