Nb-Pd-Ti BCC thin films for hydrogen separation
Piskin, Fatih; Öztürk, Tayfur (2019-02-15)
An investigation was carried out into Nb-Pd-Ti ternary system to determine possible body-centered cubic (b.c.c.) membranes that can be used for hydrogen separation. A library of thin films was produced covering the greater portion of Nb-Pd-Ti ternary diagram using a combinatorial approach. The library was screened both structurally and in terms of a reactivity index defined as the ratio of the resistivity measured in the films under hydrogen and argon. The study showed that a substantial portion of composit...
NFA Based Regular Expression Matching on FPGA
Sert, Kamil; Bazlamacci, Cuneyt F. (2021-01-01)
String matching is about finding all occurrences of a string within a given text. String matching algorithms have important roles in various real world areas such as web and security applications. In this work, we are interested in solving regular expression matching hence a more general form of string matching problem targeting especially the field of network intrusion detection systems (NIDS). In our work, we enhance a non-deterministic finite automata (NFA) based method on FPGA considerably. We propose t...
NekRS, a GPU-accelerated spectral element Navier–Stokes solver
Fischer, Paul; Kerkemeier, Stefan; Min, Misun; Lan, Yu-Hsiang; Phillips, Malachi; Rathnayake, Thilina; Merzari, Elia; Tomboulides, Ananias; Karakuş, Ali; Chalmers, Noel; Warburton, Tim (2022-12-01)
The Author(s)The development of NekRS, a GPU-oriented thermal-fluids simulation code based on the spectral element method (SEM) is described. For performance portability, the code is based on the open concurrent compute abstraction and leverages scalable developments in the SEM code Nek5000 and in libParanumal, which is a library of high-performance kernels for high-order discretizations and PDE-based miniapps. Critical performance sections of the Navier–Stokes time advancement are addressed. Performance re...
NiMoS/gamma-Al2O3 catalysts: The nature and the aging behavior of active sites in HDN reactions
ZHANG, LEE P; Karakaş, Gürkan; OZKAN, UMIT S (Elsevier BV, 1998-09-10)
The work presented in this paper is a continuation of our earlier work aimed at acquiring a fundamental understanding of sulfided Ni-Mo/gamma-Al2O3 catalysts in HDN catalysis, A series of temperature-programmed desorption and reduction experiments were performed over in-situ sulfided bare gamma-alumina support, alumina-supported monometallic Ni, Mo, and bimetallic NiMo catalysts. The TPD and TPR results were linked to the active site assignment of Ni- and Mo-associated centers in HDN reactions. Postreaction...
EFL learning environment: a theoretical model suggestion and instrument development
Mutlu, Gülçin; Yıldırım, Ali (2017-10-21)
Learning environments research is a firmly established research venue in educational research and Fraser (1998, p. 7) points out the presence of “a rich diversity of valid, economical and widely-applicable assessment instruments” to examine classroom learning environments. In line with Fraser (1998), there are some extremely popular instruments to investigate classroom learning environments in the literature; however, given these instruments, it is seen that they all focus on several facets of a general cla...
