the aim of this paper is to evaluate the effect of tectonic on the volume of alluvial fans around danehkhoshk anticline. to achieve the purpose of this study, at first, borders, sweep angle(s) and radius(r) of alluvial fans were obtained based on quick bird satellite image and then difference in the altitude between the apex and toe of alluvial fans (h) were calculated based on topographic map ...

This paper focuses on such characteristics of leaders that foster the transformation processes. In particular, analyses coefficient vital energy as a significant resource for achieving sustainable development goals. Considered in comparison with inefficient use burnout, emphasizes importance life-work balance and possibility recharging leaders. Moreover, accent is given to specificity changes r...

A simple method for the direct determination of the air-loop volume in a RAD7 system as well as the radon partition coefficient was developed allowing for an accurate measurement of the radon activity in any type of water. The air-loop volume may be measured directly using an external radon source and an empty bottle with a precisely measured volume. The partition coefficient and activity of ra...

This article treats the problem of learning a dictionary providing sparse representations for a given signal class, via l1 minimisation. The problem is to identify a dictionary Φ from a set of training samples Y knowing that Y = ΦX for some coefficient matrix X. Using a characterisation of coefficient matrices X that allow to recover any basis as a local minimum of an l1 minimisation problem, i...

Usually, in concentration polarization models, the mass transfer coefficient is an unknown parameter. Also, its variation with changing experimental circumstances is in question. In the literature, many relationships can be found to describe the mass transfer coefficient under various conditions, as well as various corrections for deviating behaviour during ultrafiltration. To obtain reliable m...
