Reducing communication volume overhead in largescale parallel SpGEMM
(Bilkent University, 201612)Sparse matrixmatrix multiplication of the form of C = A x B, C = A x A and C = A x AT is a key operation in various domains and is characterized with high complexity and runtime overhead. There exist models for parallelizing ... 
Reducing latency cost in 2D sparse matrix partitioning models
(Elsevier BV, 2016)Sparse matrix partitioning is a common technique used for improving performance of parallel linear iterative solvers. Compared to solvers used for symmetric linear systems, solvers for nonsymmetric systems offer more ... 
Reducing memory space consumption through dataflow analysis
(Pergamon Press, 2011)Memory is a key parameter in embedded systems since both code complexity of embedded applications and amount of data they process are increasing. While it is true that the memory capacity of embedded systems is continuously ... 
Reducing MLFMA memory with outofcore implementation and datastructure parallelization
(IEEE, 2013)We present two memoryreduction methods for the parallel multilevel fast multipole algorithm (MLFMA). The first method implements outofcore techniques and the second method parallelizes the preprocessing data structures. ... 
Reducing processormemory performance gap and improving networkonchip throughput
(Bilkent University, 201902)Performance of computing systems has tremendously improved over last few decades primarily due to decreasing transistor size and increasing clock rate. Billions of transistors placed on a single chip and switching at ... 
Reducing query overhead through route learning in unstructured peertopeer network
(Academic Press, 200905)In unstructured peertopeer networks, such as Gnutella, peers propagate query messages towards the resource holders by flooding them through the network. This is, however, a costly operation since it consumes node and ... 
Reducing RouterCrossings in a Mobile Intranet
(Springer, 1998)Current general purpose mobility solutions like MobileIP involve multiple routercrossings even when the mobile host moves within an intranet from one subnet of a router to another. An environment consisting of a large ... 
Reducing the dispersion errors of the finitedifference timedomain method for multifrequency planewave excitations
(Taylor & Francis, 2003)We demonstrate the applications of discretetime signalprocessing (SP) techniques for the purpose of generating accurate plane waves in the finitedifference timedomain (FDTD) method. The SP techniques are used either ... 
A reduction in the number of active components used in transconductance grounded capacitor filters
(IEEE, 1990)The number of active components in transconductance grounded capacitor filters is reduced. This reduction is possible in the case where capacitor loops and/or inductor cutsets exist in LCladder prototype. A more significant ... 
Reduction of effects of inactive array elements in phase aberration correction
(IEEE, 1993)Phase aberration correction based on time delay estimation via minimization of sum of absolute difference (SAD) between radio frequency (RF) signals of neighboring elements is studied in the presence of missing elements. ... 
Reduction of implant RF heating through modification of transmit coil electric field
(WILEY, 20101208)In this work, we demonstrate the possibility to modify the electricfield distribution of a radio frequency (RF) coil to generate electric fieldfree zones in the body without significantly altering the transmit sensitivity. ... 
Reduction of the radiofrequency heating of metallic devices using a dual‐drive birdcage coil
(Wiley, 2013)In this work, it is demonstrated that a dualdrive birdcage coil can be used to reduce the radiofrequency heating of metallic devices during magnetic resonance imaging. By controlling the excitation currents of the two ... 
Reduction of thermal strain induced rate error for navigation grade fiber optic gyroscope
(Institute of Electrical and Electronics Engineers, 2018)In this paper, we present the latest efforts of developing a navigation grade fiber optic gyroscope coil in Turkey. One of the main precision limits for a fiber optic gyroscope coil is its sensitivity to thermally induced ... 
Reduction of thermal strain induced rate error for navigation grade fiber optic gyroscope
(Optical Society of America, 2018)This paper presents an 8fold reduction of thermal sensitivity of a navigation grade fiber optic gyroscope (FOG) coil. We used an advanced thermal modeling of a fiber optic gyroscope coil to obtain the strain fields along ... 
Reductive deposition of Au3+(aq) on oxidized silicon surfaces
(N R C Research Press, 2000)Xray photoelectron spectroscopy (XPS) is used to determine the oxidation state of gold deposited from an aqueous solution of AuCl4 on to various oxidized surfaces of silicon. Although the observed Au4f signal decreased ... 
Reducts of random hypergraphs
(Elsevier BV, 19960805)For each k ⩾ 1, let Γk be the countable universal homogeneous khypergraph. In this paper, we shall classify the closed permutation groups G such that Aut(Γk) ⩽ G ⩽ Sym(Γk). In particular, we shall show that there exist ... 
Redundant expression of canonical Wnt ligands in human breast cancer cell lines
(Spandidos Publications Ltd., 2006)Human breast cancer displays nuclear accumulation of βcatenin and induction of cyclin D1 expression, which suggests that canonical Wnt/βcatenin signaling is activated. In other cancers, the activation of canonical ... 
Referencing for cohesion in L2 academic writing: a corpus analysis
(Bilkent University, 201806)Cohesion in academic and other writing is essential to effective communication. Teachers of English for academic purposes (EAP) place a great deal of emphasis on achieving cohesion, principally through coordinators and ...
