Animated mesh simplification based on saliency metrics
(Bilkent University, 2008)Mesh saliency identifies the visually important parts of a mesh. Mesh simplification algorithms using mesh saliency as simplification criterion preserve the salient features of a static 3D model. In this thesis, we propose ... -
Animation of deformable models
(Pergamon Press, 1994)Although kinematic modelling methods are adequate for describing the shapes of static objects, they are insufficient when it comes to producing realistic animation. Physically based modelling remedies this problem by ... -
Computational homogenization of soft matter friction: Isogeometric framework and elastic boundary layers
(John Wiley and Sons Ltd, 2014)SUMMARY: A computational contact homogenization framework is established for the modeling and simulation of soft matter friction. The main challenges toward the realization of the framework are (1) the establishment of a ... -
Deformation and finite size effects in cooperative molecular motors
(Bilkent University, 2002-07)Motor protein systems have been of considerable interest lately. In these studies muscle contraction is modeled as the sliding of two filaments made of protein particles over one another, that is the sliding of the ... -
Example-based retargeting of human motion to arbitrary mesh models
(Blackwell Publishing Ltd, 2015)We present a novel method for retargeting human motion to arbitrary 3D mesh models with as little user interaction as possible. Traditional motion-retargeting systems try to preserve the original motion, while satisfying ... -
Formulation of the Reynolds equation on a time-dependent lubrication surface
(Royal Society of London, 2016)The Reynolds equation, which describes the lubrication effect arising through the interaction of two physical surfaces that are separated by a thin fluid film, is formulated with respect to a continuously evolving third ... -
Homogenization of soft interfaces in time-dependent hydrodynamic lubrication
(Springer Verlag, 2015)The difficulty behind the unsteady lubrication problem is the oscillation of the film thickness in both position and time. The present study aims to extend the multiscale analysis of lubricated interfaces to the unsteady ... -
Intimate relationship between structural deformation and properties of single-walled carbon nanotubes
(Cambridge, 2002)Carbon nanotubes continue to surprise scientists with their novel properties. Recently we have discovered many intimate relationships between structural deformation and the properties of single-walled nanotubes (SWNT), ... -
Modeling and animating personalized faces
(Bilkent University, 2002)A very important and challenging problem in computer graphics is modeling and animation of individualized face models. In this thesis, we describe a facial modeling and animation system attempting to address this problem. ... -
Monodromy groups of real Enriques surfaces
(2012)We compute the monodromy groups of real Enriques surfaces of hyperbolic type. The principal tools are the deformation classification of such surfaces and a modified version of Donaldson's trick, relating real Enriques ... -
Monodromy groups of real Enriques surfaces
(Bilkent University, 2012-09)In this thesis, we compute the monodromy groups of real Enriques surfaces. The principal tools are the deformation classification of such surfaces and a modified version of Donaldson’s trick, relating real Enriques ... -
Strained band edge characteristics from hybrid density functional theory and empirical pseudopotentials: GaAs, GaSb, InAs and InSb
(Institute of Physics Publishing Ltd., 2016)The properties of a semiconductor are drastically modified when the crystal point group symmetry is broken under an arbitrary strain. We investigate the family of semiconductors consisting of GaAs, GaSb, InAs and InSb, ... -
A theoretical study on silicon and III-V compound nanotubes
(TÜBİTAK, 2005)In this paper we present a theoretical study on single-wall silicon and III-V compound nanotubes. First principles plane wave calculations within density functional theory are used to predict energetics and electronic ... -
A three-dimensional nonlinear finite element method implementation toward surgery simulation
(Bilkent University, 2011)Finite Element Method (FEM) is a widely used numerical technique for finding approximate solutions to the complex problems of engineering and mathematical physics that cannot be solved with analytical methods. In most ... -
Tuning macroscopic sliding friction at soft contact interfaces: interaction of bulk and surface heterogeneities
(Elsevier Ltd, 2016)Macroscopic frictional response of soft interfaces is strongly governed by the interaction of surface heterogeneities such as micro-texture features with bulk heterogeneities such as voids or inclusions beneath the highly ... -
Watermarking based on discrete wavelet transform and q-deformed chaotic map
(Elsevier Ltd, 2017)Hierarchy of one-dimensional ergodic chaotic maps with Tsallis type of q-deformation are studied. We find that in the chaotic region, these maps with q-deformation are ergodic as the Birkhoff ergodic theorem predicts. ...
