The frictional contact problem of sliding rigid parabolic stamps on graded materials

Güler, Mehmet Ali; Erdoğan, F; Dag, S (2008-02)

This study presents an analytical procedure to determine the contact stress distribution at the surface of an FGM coating perfectly bonded to a homogeneous substrate. The coating is assumed to be loaded by a rigid stamp ...
From location to location pattern privacy in location-based services

Abul, Osman; Bayrak, Cansın (Springer London, 2018-09-01)

Location privacy is extensively studied in the context of location-based services (LBSs). Typically, users are assigned a location privacy profile and the precise locations are cloaked so that the privacy profile is not ...
GRIM-Filter: Fast seed location filtering in DNA read mapping using processing-in-memory technologies

Kim, Jeremie S.; Senol Cali, Damla; Xin, Hongyi; Lee, Donghyuk; Ghose, Saugata; Alser, Mohammed; Hassan, Hasan; Ergin, Oğuz; Alkan, Can; Mutlu, Onur (BioMed Central Ltd., 2018-05-09)
