Acoustical design and noise control in metro stations: Case studies of the Ankara metro system
(2007)The aim of this research is to demonstrate the importance of initial strategies in acoustical design of underground metro stations. The paper searches for practical design solutions by evaluating different materials for ... -
Adaptive filtering approaches for non-Gaussian stable processes
(IEEE, 1995-05)A large class of physical phenomenon observed in practice exhibit non-Gaussian behavior. In this paper, α-stable distributions, which have heavier tails than Gaussian distribution, are considered to model non-Gaussian ... -
Adaptive methods for dithering color images
(Institute of Electrical and Electronics Engineers, 1997-07)Most color image printing and display devices do not have the capability of reproducing true color images. A common remedy is the use of dithering techniques that take advantage of the lower sensitivity of the eye to spatial ... -
Adaptive OFDM modulation for underwater acoustic communications: Design considerations and experimental results
(Institute of Electrical and Electronics Engineers Inc., 2014)In this paper, we explore design aspects of adaptive modulation based on orthogonal frequency-division multiplexing (OFDM) for underwater acoustic (UWA) communications, and study its performance using real-time at-sea ... -
Adaptive polyphase subband decomposition structures for image compression
(IEEE, 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. ... -
Adaptive schemes for location update generation in execution location-dependent continuous queries
(Elsevier Inc., 2006-04)An important feature that is expected to be owned by today's mobile computing systems is the ability of processing location-dependent continuous queries on moving objects. The result of a location-dependent query depends ... -
AIMD-based online MPLS traffic engineering for TCP flows via distributed multi-path routing
(Springer, 2004)With this paper, we propose a distributed online traffic engineering architecture for MPLS networks. In this architecture, a primary and secondary MPLS LSP are established from an ingress LSR to every other egress LSR. We ... -
Algebraic reconstraction for 3D magnetic resonance-electrical impedance tomography (MREIT) using one component of magnetic flux density
(Institute of Physics and Engineering in Medicine, 2004)Magnetic resonance-electrical impedance tomography (MREIT) algorithms fall into two categories: those utilizing internal current density and those utilizing only one component of measured magnetic flux density. The latter ... -
Analysis of assembly systems for interdeparture time variability and throughput
(Taylor & Francis, 2002)This paper studies the effect of the number of component stations (parallelism), work transfer, processing time distributions, buffers and buffer allocation schemes on throughput and interdeparture time variability of ... -
Analysis of concurrency control protocols for real-time database systems
(Elsevier, 1998)This paper provides an approximate analytic solution method for evaluating the performance of concurrency control protocols developed for real-time database systems (RTDBSs). Transactions processed in a RTDBS are associated ... -
Analysis of the 2D nonconcentric large reflector antenna-in-radome system: H-polarization case
(IEEE, 2004)2D nonconcentric reflector antenna-in-radome system is analyzed for H-polarization case. Rigorous formulation is performed depending on the MoR, Green's function and CSP methods. Larger geometries are solved in reasonable ... -
Analytic modeling of loss and cross-coupling in capacitive micromachined ultrasonic transducers
(IEEE, Piscataway, NJ, United States, 1998)The structural loss mechanism of capacitive micromachined ultrasonic transducer (cMUT) is investigated using finite element analysis and the normal mode theory. A single micromachined transducer membrane on an infinite ... -
Analytic thermal modeling for dc-to-midrange modulation frequency responses of thin-film high-Tc superconductive edge-transition bolometers
(Optical Society of America, 2001)Thin-film superconductive edge-transition bolometers are modeled with a one-dimensional analytic thermal model with joule heating, film and substrate materials, and the physical interface effects taken into consideration. ... -
Analytical model of asynchronous shared-per-wavelength multi-fiber optical switch
(IEEE, 2011)In this paper, a buffer-less shared-per-wavelength optical switch is equipped with multi-fiber interfaces and operated in asynchronous context. An analytical model to evaluate loss performance is proposed using an approximate ... -
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 ... -
An animation system for fracturing of rigid objects
(Springer, Berlin, Heidelberg, 2005)This paper describes a system for the animation of fracturing brittle objects. The system combines rigid body simulation methods with a constraint-based model to animate fracturing of arbitrary polyhedral shaped objects ... -
