    • q-Gaussian trial function in high density Bose-Einstein condensates 

      Erdemir, E.; Tanatar, Bilal (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 ...

      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 maps and Bockstein closed group extensions 

      Pakianathan, J.; Yalçın, E. (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. ...

      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 

      Köroǧlu, H.; Morgül, Ö. (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 

      Kazıklı, Ertan; Gezici, Sinan; Yüksel, S. (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 

      Berk, A.; Giles, H. (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 

      Çulha, Utku; Saranlı, Uluç (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 ...
    • Quadrupolar spectra of nuclear spins in strained InxGa1−xAs quantum dots 

      Bulutay, C. (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 

      Tayeb, J.; Ulusoy, Özgür; Wolfson, O. (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 

      Yılmazer, Semiha; Acun, Volkan (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 ...
    • Qualitative test-cost sensitive classification 

      Cebe, M.; Gunduz Demir, C. (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 assessment in the blog space 

      Schaal, M.; Fidan G.; Müller, R.M.; Dagli O. (2010)
      Purpose: The purpose of this paper is the presentation of a new method for blog quality assessment. The method uses the temporal sequence of link creation events between blogs as an implicit source for the collective tacit ...
    • Quality comparison and acceleration for digital hologram generation method based on segmentation
