High-performance nested CEP query processing over event streams
(IEEE, 2011)Complex event processing (CEP) over event streams has become increasingly important for real-time applications ranging from health care, supply chain management to business intelligence. These monitoring applications submit ... -
Static analysis of multi-staged programs via unstaging translation
(ACM, 2011)Static analysis of multi-staged programs is challenging because thebasic assumption of conventional static analysis no longer holds: the program text itself is no longer a fixed static entity, but rather a dynamically ... -
Towards subtyped program generation in F#
(ACM, 2011)Program Generation is the technique of combining code fragments to construct a program. In this work we report on our progress to extend F# with program generation constructs. Our prototype implementation uses a translation ... -
Infrastructure-to-vehicle cooperative communications with decode-and-forward relaying
(IEEE, 2011)In this paper, we consider infrastructure-to-vehicle cooperative communications in which roadside access points use vehicles as relaying terminals. This can be particularly useful in suburban or remote areas where the ... -
Low-loss optical switch using Brewster angle
(IEEE, 2011)Fabrication and actuation errors of submicron silicon waveguide optical switches are reported to remain within sub-100 nm ranges. These errors cause high loss ruining the optical performance of the switches at the on-state. ... -
Information theoretic performance of cooperative underwater acoustic communications
(IEEE, 2011)Cooperative communication is considered as a major enabling technique to meet the demanding performance requirements of future underwater acoustic (UWA) communication systems. In this paper, we investigate the information ... -
Cooperative inter-vehicular communications in highway traffic
(2011)In this paper, we investigate the performance of a single relay assisted cooperative vehicular network in a highway traffic scenario. Source and relaying vehicles are assumed to be traveling in the same direction with ... -
The semileptonic B to K1(1270, 1400) decays in QCD sum rules
(IOP Publishing, 2011)We analyze the semileptonic rare decays of the B meson to K1(1270) and K1(1400) axial vector mesons. The B → K1(1270, 1400)_+_− decays are significant flavor-changing neutral current decays of the B meson. These decays are ... -
Runtime verification of component-based embedded software
(Springer, 2011)To deal with increasing size and complexity, component-based software development has been employed in embedded systems. Due to several faults, components can make wrong assumptions about the working mode of the system and ... -
Engineering with and for light absorption and scattering: a quarter century of experimental research at RTL
(Accademia Peloritana dei Pericolanti, 2011)Characterization of particles requires detailed understanding of light interaction with homogeneous/inhomogeneous and regular/irregular shaped particles, or fractallike structures, within optically thin or thick media. ... -
Discrete dipole approximation of gold nanospheres on substrates: considerations and comparison with other discretization methods
(AAPP Physical, Mathematical, and Natural Sciences, 2011)We embark on this preliminary study of the suitability of the discrete dipole approximation with surface interaction (DDA-SI) method to model electric field scattering from noble metal nano-structures on dielectric substrates. ... -
Finding event correlations in federated wireless sensor networks
(IEEE, 2011)Event correlation engines help us find events of interest inside raw sensor data streams and help reduce the data volume, simultaneously. This paper discusses some of the challenges faced in finding event correlations over ... -
Outage analysis of Hybrid-ARQ protocols in coherent free-space optical communications
(IEEE, 2011)In this paper, we investigate the performance of automatic retransmission request (ARQ) protocols in coherent free-space optical (FSO) communications. Specifically, we study the outage performance of three different ... -
DMT analysis of multi-hop coherent FSO communication over atmospheric channels
(IEEE, 2011)In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of a multi-hop coherent free-space optical (FSO) system over atmospheric channels. We consider a relay-assisted FSO system with decode-and-forward ... -
EM-based joint time delay and channel estimation for cooperative communications
(IEEE, 2011)In this paper, we study joint time delay and channel estimation for a cooperative communication system with amplify-and-forward (AF) relaying. The proposed joint estimator is based on Expectation-Maximization (EM) algorithm ... -
T-matrix method for modelling optical tweezers
(Taylor & Francis, 2011)We review the use of the T-matrix description of scattering, or the T-matrix method, for the calculation of optical forces and torques, especially for the computational modelling of optical tweezers. We consider both simple ... -
Pool boiling critical heat flux in dielectric liquids and nanofluids
(Elsevier, 2011)With the recent advances in consumer and power electronics, efficient thermal management of high heat flux components has taken on new urgency. While its inherent advantages have made air cooling the method of choice for ... -
Coexistence of multiple regimes for near-field thermal radiation between two layers supporting surface phonon polaritons in the infrared
(American Physical Society, 2011)We demonstrate the coexistence of different near-field thermal radiation regimes between two layers supporting surface phonon polaritons (SPhPs) in the infrared. These regimes existwhen the distance of separation between ... -

Gauss karışım modeli tabanlı konuşmacı doğrulama sistemlerinde kişiye ve kanala uyarlanmada klasik MAP tabanlı yöntemlerin performans analizi
(IEEE, 2011)In this paper, performance of Gaussian mixture models (GMM) based algorithms implemented in Speech Processing Laboratory at Ozyegin University, within NIST SRE2004 and 2006 database was reported. Gaussian mixture models ...
