Artificial neural network modeling and simulation of in-vitro nanoparticle-cell interactions
(American Scientific Publishers, 2014)In this research a prediction model for the cellular uptake efficiency of nanoparticles (NPs), which is the rate that NPs adhere to a cell surface or enter a cell, is investigated via an artificial neural network (ANN) ... -
Association rules for supporting hoarding in mobile computing environments
(IEEE, 2000)One of the features that a mobile computer should provide is disconnected operation which is performed by hoarding. The process of hoarding can be described as loading the data items needed in the future to the client cache ... -
Automated detection and enhancement of microcalcifications in mammograms using nonlinear subband decomposition
(IEEE, 1997)In this paper, computer-aided detection and enhancement of microcalcifications in mammogram images are considered. The mammogram image is first decomposed into subimages using a `subband' decomposition filter bank which ... -
Automatic Ranking of Retrieval Systems in Imperfect Environments
(ACM, 2003-07-08)The empirical investigation of the effectiveness of information retrieval (IR) systems requires a test collection, a set of query topics, and a set of relevance judgments made by human assessors for each query. Previous ... -
Balancing energy loads in wireless sensor networks through uniformly quantized energy levels-based clustering
(IEEE, 2010)Clustering is considered a common and an effective method to prolong the lifetime of a wireless sensor network. This paper provides a new insight into the cluster formation process based on uniformly quantizing the residual ... -

(IEEE, 2006-04)This paper presents a method for the automatic generation of different building models to be used to populate virtual cities and a system of visualization of generated city models. The proposed method incorporates randomness ... -
Binary morphological subband decomposition for image coding
(IEEE, 1996)In this paper a binary waveform coding method based on morphological subband decomposition coupled with embedded zero-tree and entropy coding is described. This method can be utilized in text compression or bit-plane coding ... -
Block SOR for Kronecker structured representations
(Elsevier, 2004)The Kronecker structure of a hierarchical Markovian model (HMM) induces nested block partitionings in the transition matrix of its underlying Markov chain. This paper shows how sparse real Schur factors of certain diagonal ... -
Chirp filtering in the fractional Fourier domain
(Optical Society of America, 1994-11-10)In the Wigner domain of a one-dimensional function, a certain chirp term represents a rotated line delta function. On the other hand, a fractional Fourier transform (FRT) can be associated with a rotation of the ... -
Circuit theoretical method for efficient finite element analysis of acoustical problems
(IEEE, 1998)In the last decade, there has been an outstanding improvement in the computer aided design tools for VLSI circuits regarding solution times and the circuit complexity. This study proposes formulating the acoustic field ... -
Circular arrays of log-periodic antennas for broadband applications
(IEEE, 2006)Circular arrays of log-periodic (LP) antennas are designed for broadband applications. A sophisticated electromagnetic simulation environment involving integral equations and fast solvers is developed to analyze the LP ... -
Coding of fingerprint images using binary subband decomposition and vector quantization
(SPIE, 1998-01)In this paper, compression of binary digital fingerprint images is considered. High compression ratios for fingerprint images is essential for handling huge amount of images in databases. In our method, the fingerprint ... -
A comparison of two methods for fusing information from a linear array of sonar sensors for obstacle localization
(IEEE, 1995)The performance of a commonly employed linear array of sonar sensors is assessed for point-obstacle localization intended for robotics applications. Two different methods of combining time-of-flight information from the ... -
A comparison study on sound defects of Bilkent Amphitheatre in terms of intelligibility of the speech
(2007)The 4000 seated multi-purpose hall Bilkent Amphitheater is a semi-closed amphitheater with a large volume of 90,000 m3.At the beginning, the amphitheater was designed only for open-air performances. Afterwards it was decided ... -
