The common vector approach and its comparison with other subspace methods in case of sufficient data
Gülmezoğlu, M. Bilginer; Dzhafarov, Vakif; Edizkan, Rıfat; Barkana, Atalay (Academic Press LTD- Elsevier Science LTD, 2007)This paper presents an application of the common vector approach (CVA), an approach mainly used for speech recognition problems when the number of data items exceeds the dimension of the feature vectors. The calculation ... -
The common vector approach and its relation to principal component analysis
The main point of the paper is to show the close relation between the nonzero principal components and the difference subspace together with the complementary close relation between the zero principal components and the ... -
Compactness of the set of trajectories of the controllable system described by an affine integral equation
Hüseyin, Nesir; Hüseyin, Anar (Elsevier Science Inc, 2013)In this paper the control system with integral constraint on the controls is studied. It is assumed that the behavior of the system is described by an affine Volterra integral equation which is nonlinear with respect to ... -

Comparison of rotordynamic coefficients for labyrinth seals using a two-control volume method
Dereli, Yılmaz (SAGE Publications LTD, 2008)In the current paper, the gas flow in straight through labyrinth seals is investigated using a two-control volume model. The continuity and the circumferential momentum equations are reobtained using the above model and ... -
Comparison of the positional absorption sets in two game approach problems
Ushakov, V. N.; Lebedev, P. D.; Guseinov, Khalik G. (IFAC Secretariat, 2012)For a given compact target set M C Rn the problem of approach at a given time instant 6 and the problem of approach to a given time instant 6 are discussed. The coincidence criteria of positional absorbtion sets, i.e. the ... -
Comparisons of rotordynamic coefficients in stepped labyrinth seals by using Colebrook-White friction factor model
Eser, Dursun; Dereli, Yılmaz (Springer, 2007)The objective of this work is to observe the effects of friction factors for the stepped labyrinth seals. The gas flow through the seals creates net pressure and shear forces acting on the rotor. It is necessary to predict ... -
Composite wave models for elastic plates
Erbaş, Barış; Kaplunov, Julius; Nolde, Evgeniya; Palsu, Melike (Royal Soc, 2018)The long-term challenge of formulating an asymptotically motivated wave theory for elastic plates is addressed. Composite two-dimensional models merging the leading or higher-order parabolic equations for plate bending and ... -
