In this article, we present the concept of supra paracompact spaces and study its basic properties. We elucidate its relationship with supra compact spaces and prove that the property of being a supra paracompact space is weakly hereditary and topological properties. Also, we provide some examples to show some results concerning paracompactness on topology are invalid on supra topology. Finally...

The inevitable depletion of mineral resources, the constant deterioration of the geological and mining conditions for the development of mineral deposits and the restoration of raw materials from mining waste by recycling are all urgent problems we face today. The solution to this problem may ensure: a considerable extension of raw material source; decrease of investments in opening new deposit...

The interrannual variability of coastal sea surface temperature (SST) anomalies confined off Senegal is explored from a new viewpoint of the ocean-land-atmosphere interaction. The phenomenon may be classified into "coastal Niño/Niña" in the North Atlantic as discussed recently in the Northeastern Pacific and Southeastern Indian Oceans. The interannual variability of the regional mixed-layer tem...

The Vereina railway tunnel drilled in Austroalpine nappes encountered little water inflows. The linear discharge rates vary between 0,003 and 0,006 l/s/m (Figure 1). Two different water temperatures series have been observed in both northern and southern parts of the tunnel trace. The northern thermal gradient is equal to 0,018°C/m while the southern thermal gradient is not very different with ...

Motivated by the construction of new examples of Artin-Schelter regular algebras of global dimension four, J.J.Zhang and J.Zhang (2008) introduced an algebra extension AP [y1, y2;σ, δ, τ ] of A, which they called a double Ore extension. This construction seems to be similar to that of a two-step iterated Ore extension over A. The aim of this paper is to describe those double Ore extensions whic...

According to the publication by US Minerals Survey in 1999, the total reserve of manganese ore in the world is 0.66 billion tons. See Table 1.

This paper focuses on the scientific problem of quantitative mineralization prediction at large depth in Zaozigou gold deposit, west Qinling, China. Five geological and geochemical indicators are used to establish model. Machine learning Deep algorithms employed for 3D Mineral Prospectivity Mapping (MPM). Especially, Student Teacher Ore-induced Anomaly Detection (STOAD) model is proposed based ...

Hyperspectral anomaly detection (AD) task is a typical binary classification problem, and utilizing background prior knowledge key technique to solving such problems. The two most commonly used priors for hyperspectral images are low-rank local smooth properties. Most traditional matrix-based methods use regularizations model these types of integrate them into one model, which makes unable maxi...
