q-Gaussian trial function in high density Bose-Einstein condensates
(Elsevier Science B.V., 2003)We study the ground-state static properties of Bose-Einstein condensates in the high density regime using a trial wave function of the form of a q-Gaussian. The flexibility afforded by a q-Gaussian trial function yields ... -
Q1D-polarons in rigid boundary cylindrical wires: "mixed-coupling approximation"
(TÜBİTAK, 1998)We consider the interaction of a confined electron with bulk polar-optical phonons in a cylindrical quantum well wire with infinite boundary potential. Expressions for the polaron self energy and mass are derived within a ... -
qPCR validation of in vivo diagnostic importance and regulation by estrogen for CHRNA5 isoform expression in breast cancer
(Bilkent University, 2014)Breast cancer has multiple molecular subtypes; normal-like, basal-like, luminal A, luminal B and HER2 positive depending on receptor status of tumor cells. Cancer therapy is tailored according to the type of cancer; hence ... -
QR-RLS algorithm for error diffusion of color images
(SPIE, 2000)Printing color images on color printers and displaying them on computer monitors requires a significant reduction of physically distinct colors, which causes degradation in image quality. An efficient method to improve the ... -

Quadratic assignment problem : linearizations and polynomial time solvable cases
(Bilkent University, 2006)The Quadratic Assignment Problem (QAP) is one of the hardest combinatorial optimization problems known. Exact solution attempts proposed for instances of size larger than 15 have been generally unsuccessful even ... -
Quadratic maps and Bockstein closed group extensions
(American Mathematical Society, 2007)Let E be a central extension of the form 0 → V → G → W → 0 where V and W are elementary abelian 2-groups. Associated to E there is a quadratic map Q: W → V, given by the 2-power map, which uniquely determines the extension. ... -
Quadratic multi-dimensional signaling games and affine equilibria
(Institute of Electrical and Electronics Engineers Inc., 2017)This paper studies the decentralized quadratic cheap talk and signaling game problems when an encoder and a decoder, viewed as two decision makers, have misaligned objective functions. The main contributions of this study ... -
Quadratic optimality of the zero-phase repetitive control
(2001)We consider the quadratically optimal repetitive control problem in discrete-time and show that the existing zero-phase repetitive controller is quadratically optimal for stable plants. Copyright © 2001 by ASME. -
Quadratic privacy-signaling games and payoff dominant equilibria
(IEEE, 2020)We consider a privacy-signaling game problem in which a transmitter with privacy concerns and a receiver, which does not pay attention to these privacy concerns, communicate. In this communication scenario, the transmitter ... -
Quadrilateral panelization of freeform surface structures
(Elsevier B.V., 2017)Freeform surfaces need to be discretized into manageable sized panels so that the surface can be fabricated in smaller pieces that are then assembled on site. This discretization process comprises numerous challenges; ... -
Quadrupedal bounding with an actuated spinal joint
(IEEE, 2011)Most legged vertebrates use flexible spines and supporting muscles to provide auxiliary power and dexterity for dynamic behaviors, resulting in higher speeds and additional maneuverability during locomotion. However, most ... -
Quadrupedal gait in humans : identification and partial characterization of a novel gene WD repeat domain 81 (WDR81)
(Bilkent University, 2011)Identi cation of disease genes responsible for cerebellar phenotypes provides mechanistic insights into the development of cerebellum. Neural pathways involved in bipedal gait in humans is not completely understood. ... -
Quadrupolar spectra of nuclear spins in strained InxGa1−xAs quantum dots
(American Physical Society, 2012)Self-assembled quantum dots (QDs) are born out of lattice mismatched ingredients where strain plays an indispensable role. Through the electric quadrupolar coupling, strain affects the magnetic environment as seen by the ... -
A quadtree-based dynamic attribute indexing method
(Oxford University Press, 1998)Dynamic attributes are attributes that change continuously over time making it impractical to issue explicit updates for every change. In this paper, we adapt a variant of the quadtree structure to solve the problem of ... -
A qualitative approach to investigate indoor soundscape of the built environment
(Institute of Noise Control Engineering, 2018)Soundscape approach takes advantage of both quantitative and qualitative research methods. So far, there have been five main research tools to collect and analyze data. Quantitative ones are consisted of, questionnaire ... -
A qualitative research on consumer's perception of prices and their evaluation of price promotions in an inflationary environment
(Bilkent University, 1996)This study aims at the formation of an understanding on how consumers process price information, what opinion they hold of price promotions and how they interpret promotion signals, reference effects of price promotions, ... -
Qualitative test-cost sensitive classification
(Bilkent University, 2008)Decision making is a procedure for selecting the best action among several alternatives. In many real-world problems, decision has to be taken under the circumstances in which one has to pay to acquire information. In ... -
Qualitative test-cost sensitive classification
(Elsevier BV, 2010)This paper reports a new framework for test-cost sensitive classification. It introduces a new loss function definition, in which misclassification cost and cost of feature extraction are combined qualitatively and the ... -
Quality and production control with opportunities and exogenous random shocks
(Bilkent University, 2005)In a production process, opportunities arise due to exogenous or indigenous factors, for cost reduction. In this dissertation, we consider such opportunities in quality control chart design and production planning for ...
