The study area, located in the southern section of the Central Iranian volcano–sedimentary complex, contains a large number of mineral deposits and occurrences which is currently facing a shortage of resources. Therefore, the prospecting potential areas in the deeper and peripheral spaces has become a high priority in this region. Different direct and indirect methods try to predict promising a...

this paper presents a robust fractional order controller for flexible-joint electrically driven robots under imperfect transformation of control space. the proposed approach is free from manipulator dynamics, thus free from problems associated with torque control strategy in the design and implementation. as a result, the proposed controller is simple, fast response and superior to the torque c...

Torque control strategy is a common strategy to control robotic manipulators. However, it becomes complex duo to manipulator dynamics. In addition, position control of Permanent Magnet Synchronous Motors (PMSMs) is a complicated control. Therefore, tracking control of robots driven by PMSMs is a challenging problem. This article presents a novel tracking control of electrically driven robots wh...

This paper presents a method with a combination of diverse approaches for requirement elicitation of a Data Warehouse (DW) schema model. This method integrates five approaches: goal-driven, user-driven, process-driven, technology-driven, and data-driven. This method includes two approaches not usually used in the DW field: process-driven and technology-driven. The role of each approach is: goal...

Our challenge was to develop tool support for the complete design trajectory from business processes to the code of the enterprise applications supporting them. To this end we integrated two commercial modelling tools: BiZZdesigner and OptimalJ. BiZZdesigner supports the modelling and analysis of business processes and uses a dedicated graphical language. OptimalJ is an Eclipse-based implementa...

background : a detailed study of hidden and hard to reach populations in order to identify their characteristics is essential because they endanger the health of the society by their dangerous behaviors. however, sampling in these populations through conventional sampling methods is impossible due to reasons such as being hidden and lacking a precise frame. methods: in this article, applicable ...
