One of the major strengths of a Geographic Information System (GIS) in geosciences is the ability to integrate and combine multiple layers into mineral potential maps showing areas which are favorable for mineral exploration. These capabilities make GIS an extremely useful tool for mineral exploration. Several spatial modeling techniques can be employed to produce potential maps. However, these...

The purpose of this study is to determine geochemical anomalies on lithogeochemical data from Ardestan area, Central Iran, using concentration-number (C-N) fractal modeling and staged factor analysis. Staged factor analysis is used to the recognition of genetic correlation and elimination of non-indicator elements in three steps. Factor scores of elements were calculated and geochemical data cl...

Background & Aims: Surgeons are not willing to participate in thyroid surgeries due to dangerous, although rare, complications of the procedure. Post thyroidectomy complications are divided in early and late onset; hypocalcemia, bleeding, thyroid storm and recurrent laryngeal nerve (RLN) injury are the most important ones. This study was performed to compare the frequency of recurrent laryngeal...

The heterogenous mineralogy of ultramafic deposits hosting mining operations makes it challenging to accurately determine the waste rock’s mineral carbonation potential (MCP). Additionally, significantly higher capabilities olivine than serpentine add difficulty. To address this issue, in work, a new and unique tool called MCP calculator was developed as Microsoft ExcelTM spreadsheet amount ant...

Three of the major problems in qualitative spatial reasoning and robotics are localization, exploration, and navigation in known or unknown environments. This paper investigates how far different qualitative methods based on angle information, most of them originally invented for the representation of spatial knowledge only, are well-suited for these tasks. It turns out that with panoramas, whi...
