A 2 dimensional solar radiation model [2 Boyutlu bir güneş işinim şiddeti modeli]
(2008)In this study solar radiation data obtained from Eskisehir region is mathematically modeled using a two dimentional (2D) approach. The approach and model is novel in the literature of solar radiation modeling. The analysis ... -
2-D analysis and compression of power-quality event data
(IEEE-Inst Electrical Electronics Engineers Inc, 2004)This paper introduces a novel two-dimensional (2-D) representation of the power quality event data. 2-D discrete-time wavelet transform is applied to the 2-D representation of real-life event data. The proposed representation ... -
A 2-D orientation-adaptive prediction filter in lifting structures for image coding
(2006)Lifting-style implementations of wavelets are widely used in image coders. A two-dimensional (2-D) edge adaptive lifting structure, which is similar to Daubechies 5/3 wavelet, is presented. The 2-D prediction filter predicts ... -
A 2D representation for analysis and coding of power quality events
(IEEE, 2003)In this work, we demonstrate examples about uses of practical image processing techniques over a new interpretation of power quality event data. Power quality event data are 1D data obtained from a real life system with ... -
A 3D Lifting Based Method Augmented by Motion Compensation for Video Coding
(IEEE, 2009)This study introduces a spatio-temporal lifting based algorithm to be used in compression of video signals. The temporal correlation of consecutive frames causes temporal redundancies, which are subject to lifting-like ... -
Active suspension design based on linear-matrix inequalities and fixed-order controllers
(2011)In this paper, influence of tire damping on multi-objective control of quarter-car suspensions excited by random road disturbances is studied. The active suspension design problem is first formulated as a mixed H 2/? ... -
Active suspension design for an idealized truck cabin
(Institute of Electrical and Electronics Engineers Inc., 2014)In this paper, a prototype three-degree-of-freedom cabin model for a commercial truck is derived to study ride motions of the cabin under random road excitations. An active suspension system is designed using the ... -
An Adaptive Algorithm for Detection of Multiple-Type, Positively Stained Nuclei in IHC images with minimal Prior Information: Application to OLIG2 Staining Gliomas
(Spie-Int Soc Optical Engineering, 2015)We propose a method to detect and segment the oligodendrocytes and gliomas in OLIG2 immunoperoxidase stained tissue sections. Segmentation of cell nuclei is essential for automatic, fast, accurate and consistent analysis ... -
Adaptive polyphase subband decomposition structures for image compression
(IEEE-Inst Electrical Electronics Engineers Inc, 2000)Subband decomposition techniques have been extensively used for data coding and analysis. In most filter banks, the goal is to obtain subsampled signals corresponding to different spectral regions of the original data. ... -
An adaptive statistical method for power quality analysis
(IEEE-Inst Electrical Electronics Engineers Inc, 2005)Digital fault recorders installed for monitoring current and/or voltage waveforms acquire and store vast amount of waveform data for post processing. Because of this, effective offline automated event detection from acquired ... -
Algorithms and software for approximating and evaluating fir filters
(Institute of Electrical and Electronics Engineers Inc., 2014)The controllers designed for time-delays systems often involve finite impulse response (FIR) filters, in particular prediction based controllers for systems with input/output delays. We present algorithms and software to ... -
Algorithms for deadlock avoidance and reversibility enforcement in discrete event systems
