Approximation of multiserver retrial queues by means of generalized truncated models
(Springer, 2002)It is wellknown that an analytical solution of multiserver retrial queues is difficult and does not lead to numerical implementation. Thus, many papers approximate the original intractable system by the socalled ... 
Binary sequences with low aperiodic autocorrelation for synchronization purposes
(IEEE, 2003)An evolutionary algorithm is used to find three sets of binary sequences of length 49100 suitable for the synchronization of digital communication systems. Optimization of the sets are done by taking into consideration ... 
Bounds on the capacity of random insertion and deletionadditive noise channels
(IEEE, 2013)We develop several analytical lower bounds on the capacity of binary insertion and deletion channels by considering independent uniformly distributed (i.u.d.) inputs and computing lower bounds on the mutual information ... 
Clientserver synchronization and buffering for variable rate multimedia retrievals
(1996)We consider the use of large buffers and feedback as a mechanism to maintain loosely coupled synchronization between a multimedia server and a client. The multimedia stream is modeled as a fluid flow through rate controlled ... 
Communication scheme by using synchronized chaotic systems
(IEEE, Piscataway, NJ, United States, 1996)A method to synchronize systems with chaotic behavior, in a masterslave configuration adapted to communication systems, is discussed. This work is motivated by the need for secure communication. In this method, the ... 
A delaytolerant asynchronous twowayrelay system over doublyselective fading channels
(Institute of Electrical and Electronics Engineers Inc., 2015)We consider design of asynchronous orthogonal frequency division multiplexing (OFDM) based diamond twowayrelay (DTWR) systems in a timevarying frequencyselective (doublyselective) fading channel. In a DTWR system, two ... 
Differential modulation for asynchronous twoway relay systems over frequencyselective fading channels
(John Wiley and Sons Ltd, 2016)We propose two schemes for asynchronous multirelay twoway relay (MRTWR) systems in which neither the users nor the relays know the channel state information. In an MRTWR system, two users exchange their messages with ... 
Efficient parallel spatial subdivision algorithm for objectbased parallel ray tracing
(Pergamon Press, 1994)Parallel ray tracing of complex scenes on multicomputers requires the distribution of both computation and scene data to the processors. This is carried out during preprocessing and usually consumes too much time and memory. ... 
Model based anticontrol of discretetiime systems
(Institute of Electrical and Electronics Engineers, 2003)We will consider a modelbased approach for the anticontrol of some discretetime systems. We first assume the existence of a chaotic model in an appropriate form. Then by using an appropriate control input we try to match ... 
A modelbased scheme for anticontrol of some chaotic systems
(World Scientific Publishing, 2003)We consider a modelbased approach for the anticontrol of some continuous time systems. We assume the existence of a chaotic model in an appropriate form. By using a suitable input, we match the dynamics of the controlled ... 
A modelbased scheme for anticontrol of some discretetime chaotic systems
(World Scientific, 2004)We consider a modelbased approach for the anticontrol of some discretetime systems. We first assume the existence of a chaotic model in an appropriate form. Then by using an appropriate control input we try to match the ... 
Observer based chaotic message transmission
(World Scientific Publishing, 2003)We consider observer based synchronization of continuoustime chaotic systems. We present two message transmission schemes for such systems. The first one is based on chaotic masking and modulation, and the second one is ... 
On the synchronization of logistic maps
(Elsevier BV, 19981026)We study the synchronization of two chaotic maps described by a logistic equation. We propose a new feedback term and show that the resulting system has some desired properties including exponential synchronization with ... 
Progressive refinement radiosity on ringconnected multicomputers
(Publ by ACM, New York, NY, United States, 1993)The progressive refinement method is investigated for parallelization on ringconnected multicomputers. A synchronous scheme, based on static task assignment, is proposed, in order to achieve better coherence during the ... 
Study of encapsulated microbubble cluster based on association schemes perspective
(Elsevier B.V., 2018)Ultrasound contrast agents have been recently utilized in therapeutical implementations for targeted delivery of pharmaceutical substances. Radial pulsations of a cluster of encapsulated microbubbles under the action of ... 
A switching synchronization scheme for a class of chaotic systems
(Elsevier, 2002)In this Letter, we propose an observerbased synchronization scheme for a class of chaotic systems. This class of systems are given by piecewiselinear dynamics. By using some properties of such systems, we give a procedure ... 
Synchronization and chaotic masking scheme based on occasional coupling
(American Physical Society, 2000)Synchronization and a related message transmission scheme using synchronized chaotic systems was presented for discretetime systems. The scheme was based on occasional coupling of transmitter and receiver systems. The ... 
Test case verification by model checking
(Kluwer Academic Publishers, 1993)Verification of a test case for testing the conformance of protocol implementations against the formal description of the protocol involves verifying three aspects of the test case: expected input/output test behavior, ... 
Ultralow timingjitter passively modelocked fiber lasers for longdistance timing synchronization
(S P I E  International Society for Optical Engineering, 2006)One of the key challenges for the nextgeneration light sources such as XFELs is to implement a timing stabilization and distribution system to enable ∼ 10 fs synchronization of the different RF and laser sources distributed ...
