the aim of this study was to identify various sulfidic mineralized zones in the ghare-tappeh cu deposit (nw iran) based on geo-electrical data including induced polarization (ip) and resistivity (rs) using the concentration-volume (c-v) and number-size (n-s) fractal models. the fractal models were used to separate high and moderate sulfidic zones from low sulfidic zones and barren wall rocks. b...

This manuscript is concerned with relating two approaches that can be used to explore complex dependence structures between categorical variables, namely Bayesian partitioning of the covariate space incorporating a variable selection procedure that highlights the covariates that drive the clustering, and log-linear modelling with interaction terms. We derive theoretical results on this relation...

The purpose of mineral exploration is to find ore deposits. The main aim of this work is to use the fuzzy inference system to integrate the exploration layers including the geological, remote sensing, geochemical, and magnetic data. The studied area was the porphyry copper deposit of the Kahang area in the preliminary stage of exploration. Overlaying of rock units and tectonic layers were used ...

Most existing approaches in Mobile Context-Aware Recommender Systems focus on recommending relevant items to users taking into account contextual information, such as time, location, or social aspects. However, none of them has considered the problem of content dynamicity. We introduce in this paper an algorithm that tackles this dynamicity. It is based on dynamic exploration/exploitation trade...

13 2 ?j-fraction of exp. (The complexity decreases from counting Turing steps to counting generic steps. We get the intersection of two sets of group elements at zero generic costs as equality tests are for free.) Corollary 12. The minimal length t of generic networks that invert a 2 ?j-fraction of exp is (p q2 ?j). Theorem 13. Every generic network A of length t with input y = exp (x) 2 G dist...

Personal time logs are collected by many people to provide insights of their work patterns and life patterns. However, the visualizations provided by the time tracking tools do not provide easy exploration and analysis. Schedulvis is designed and implemented to help people analyze personal time log data on desired long term activities. The system contains two main views, the calendar view and t...

Resources/reserves classification is crucial for block model creation utilised in mine planning and feasibility study. Selection of estimation methods is an essential part of mineral exploration and mining activities. In other word, resources classification is an issue for mining companies, investors, financial institutions and authorities, but it remains subject to some confusion. The aim of t...

This study was carried out to determine some biological characteristics including age, growth and somatic condition of Carasobarbus luteus and Capoeta trutta in the Turkish part of the Tigris River. The examined samples of C. luteus were distributed between II-IX years of age. The length-weigth relations of females and males were calculated as Log W =-4.7314 +3.0113 Log FL and Log W = -4.7631 +...
