Numerical solution of non-conservative linear transport problems
(Işık University Press, 2018)
In this study, trigonometric cubic B-spline differential quadrature method is developed for a linear transport problems constructed on the advection-diffusion equation. The weighting coefficients used in the derivative ...
A pre-subadditive fuzzy measure model and its theoretical interpretation
(Işık University Press, 2020)
In this paper a particular set function which depends on densities of singletons with interdependence coefficients and which provides redundancy among singletons is considered. The Möbius representation of this function ...
One-dimensional cutting stock problem with divisible items: a case study in steel industry
(Işık University Press, 2019)
This paper considers the one-dimensional cutting stock problem (1D-CSP) with divisible items, which arises in the steel industries. While planning the steel cutting operations, each item can be divided into smaller pieces, ...
Numerical treatment of newell-whitehead-segel equation
(Işık University Press, 2020)
In this paper, a comparative study of recently developed numerical methods in solving nonlinear Newell-–Whitehead—Segel equations is carried out. Results computed using Variational iteration method (VIM) are compared with ...
Modeling of electrocardiogram signals using predefined signature and envelope vector sets
(Hindawi Publishing Corporation, 2007)
A novel method is proposed to model ECG signals by means of "predefined signature and envelope vector sets (PSEVS)." On a frame basis, an ECG signal is reconstructed by multiplying three model parameters, namely, predefined ...
Rate-distortion and complexity optimized motion estimation for H.264 video coding
(IEEE-INST Electrical Electronics Engineers Inc, 2008-02)
11.264 video coding standard supports several inter-prediction coding modes that use macroblock (MB) partitions with variable block sizes. Rate-distortion (R-D) optimal selection of both the motion vectors (MVs) and the ...
A robust localization framework to handle noisy measurements in wireless sensor networks
(IEEE, 2009-09-14)
We construct a robust localization framework to handle noisy measurements in wireless sensor networks. Traditionally many approaches employ the distance information gathered from ranging devices of the sensor nodes to ...
Hierarchical quantization indexing for wavelet and wavelet packet image coding
(Elsevier Science BV, 2010-02)
In this paper, we introduce the quantization index hierarchy, which is used for efficient coding of quantized wavelet and wavelet packet coefficients. A hierarchical classification map is defined in each wavelet subband, ...
EM-Based sequence estimation for wireless systems with orthogonal transmit diversity
(IEEE, 2003)
In this paper, an optimum sequence estimation algorithm for wireless systems with Alamouti's two transmitter diversity in the presence of multipath fading is proposed. The algorithm is based on a jointly iterative channel ...
Compression of ECG signals using variable-length classified vector sets and wavelet transforms
(Springer International Publishing AG, 2012)
In this article, an improved and more efficient algorithm for the compression of the electrocardiogram (ECG) signals is presented, which combines the processes of modeling ECG signal by variable-length classified signature ...
