in this paper an application of gustafson-kessel clustering algorithm is presented to create a fault detection map (fdm). five post-stack seismic attributes are extracted from a desired seismic time slice related to 3d seismic data of a gas field located in southwest of iran. to find the optimal cluster numbers, two frequently used clustering validity measures, i.e. sc and xb, are used and then...

To a visually impaired individual the physical world presents many challenges. For a person with impaired sight, wayfinding through a complex environment is fraught with dangers, both actual and imagined. The current generation of mobility aids have the possibility of addressing a broad range of physical issues through technological solutions. The perception of difficulty however, can mean that...

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 123. 75 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9592-3. Hepatocyte transplantation is an attractive method for the treatment of metabolic liver disease and acute liver failure. The clinical application of th...

One of the major computational tasks of using the traditional cutting plane approach to solve linear semi-infinite programming problems lies in finding a global optimizer of a nonlinear and nonconvex program. This paper generalizes the Gustafson and Kortanek scheme to relax this requirement. In each iteration, the proposed method chooses a point at which the infinite constraints are violated to...

We announce proofs of Macdonald's constant term conjectures for the affine root systems S(F4) and S(F4) U . We also give an algorithm for deciding the conjectures for the remaining root systems S(E6), S(E7), and S(E%) and prove that the constant term in question can indeed be expressed in closed form. Combined with previous work of ZeilbergerBressoud, Kadell, and Gustafson, our results imply th...

According to the growth of the Internet technology, there is a need to develop strategies in order to maintain security of system. One of the most effective techniques is Intrusion Detection System (IDS). Clustering which is commonly used to detect possible attacks is one of the branches of unsupervised learning. Fuzzy clustering algorithms play an important role to reduce spurious alarms and I...

One of the major computational tasks of using the traditional cutting plane approach to solve linear semi-in nite programming problems lies in nding a global optimizer of a non-linear and non-convex program. This paper generalizes Gustafson and Kortanek's scheme to relax this requirement. In each iteration, the proposed method chooses a point at which the in nite constraints are violated to a d...

Online forum participation Whereas ‘back in the old days’ individuals depended on experts and close relatives for health information, nowadays individuals are turning to the Internet to look for information about health-related issues (Rice, 2006). A rapidly increasing number of healthrelated support groups provide users with ample opportunities to share their personal stories online. Online su...
