In arid and semi-arid lands like Iran water is scarce, not all the wastewater can be treated. Hence, groundwater remains primary principal source of supply for human consumption. Therefore, this study attempted to spatially assess potential in an aquifer a region using geographic information systems (GIS)-based statistical modeling. To end, 75 agricultural wells across Marvdasht Plain were samp...

Laparoscopic liver resection (LLR) is safer and more advantageous than open surgery regarding morbidity, blood loss, length of hospital stay. Several radiological studies surgical strategies confirmed that the anatomy complex what Couinad described. Intraoperative ultrasound (IOUS) has become an indispensable tool to identify “real anatomy” plan a tailored LLR because wide sub-segmentary variab...

This paper presents a grid-based scan-to-map matching technique for accurate 2D map building. At every acquisition of a new scan, the proposed technique matches the new scan to the previous scan similarly to the conventional techniques, but further corrects the error by matching the new scan to the globally defined map. In order to achieve best scan-to-map matching at each acquisition, the map ...

A technique for optimising the efficiency of sub-map method for large-scale simultaneous localisation and mapping (SLAM) is proposed. It optimises the benefits of the sub-map technique to improve the accuracy and consistency of an Extended Kalman Filter (EKF) based SLAM. Error models were developed and engaged to investigate some of the outstanding issues in employing sub-map technique in SLAM....

A recently proposed swarm intelligence technique for Fuzzy Cognitive Map learning is described. The technique employs the Particle Swarm Optimization algorithm to minimize a proper objective function, whose global minimizers correspond to suboptimal weight matrices of the Fuzzy Cognitive Map. New instances of an industrial test problem are studied, justifying the usefulness of the technique as ...
