determination of stockpile weight and stockpile inventory are critical to any quarry or mining operation, whether it is required by accounting firms or used internally for the quarterly balance of production and sales. generally, errors and problems originate from two factors. volume of stockpile that is traditionally worked out from the mapping results has a low accuracy due to irregular shape...

A density network is a neural network that maps from unobserved inputs to observable outputs. The inputs are treated as latent variables so that, for given network parameters, a non{trivial probability density is deened over the output variables. This probabilistic model can be trained by various Monte Carlo methods. The model can discover a description of the observed data in terms of an under...

Physical density is a numerical measure of the concentration of individuals or physical structures within a given geographical unit. It is an objective, quantitative and neutral spatial indicator. However, in practice, physical density takes on a real meaning only if it is related to a specified scale of reference. For instance, density expressed as ratio of population to land area can vary sig...

background: due to its minimal systematic adverse effects, transdermal estrogen is widely used for the prevention of osteoporosis in postmenopausal women.the present meta-analysis aimed to clarify the effects of transdermal estrogen on bone mineral density (bmd) of postmenopausal women.methods: studies were identified by searching electronic databases including cochrane library, medline, embase...

    Sampling methods have a theoretical basis and should be operational in different forests; therefore selecting an appropriate sampling method is effective for accurate estimation of forest characteristics. The purpose of this study was to estimate the stand density (number per hectare) in Arasbaran forest using a variety of the plotless density estimators of the nearest neighbors sampling me...

Background and Aim: Cutaneous squamous cell carcinoma (CSCC) is the second most common skin cancer. Mast cells may play a role in tumor progression and metastasis by increasing angiogenesis. The aim of this study was to investigate the role of mast cells by increasing angiogenesis in invasion of head and neck cutaneous squamous cell carcinoma. Materials and Methods: In this cross-sectional stud...

Density estimation is a fundamental task in statistics and machine learning that aims to estimate, from set of samples, the probability density function distribution generated them. There are different methods for addressing this problem but recently deep-neural have emerged as powerful alternative. This paper presents novel method neural based on matrices adaptive Fourier features. commonly us...

Abstract We show that there exist uncountably many (tall and nontall) pairwise nonisomorphic density-like ideals on $\omega $ which are not generalized density ideals. In addition, they nonpathological. This answers a question posed by Borodulin-Nadzieja et al. in [this Journal , vol. 80 (2015), pp. 1268–1289]. Lastly, we provide sufficient conditions for ideal to be necessarily ideal.
