Caching to the Sky: Performance Analysis of Cache-Assisted CoMP for Cellular-Connected UAVs
(2019)Providing connectivity to aerial users, such as cellular-connected unmanned aerial vehicles (UAVs) or flying taxis, is a key challenge for tomorrow’s cellular systems. In this paper, the use of ... -
Calculation of the rise transient and relaxation time of the induced dipole Kerr effect
(American Physical Society, 1996)The exact calculation of the rise transient of the birefringence and the corresponding relaxation times by different theoretical methods is described, in particular the Kerr-effect response of an assembly of nonpolar but ... -
Carrier Aggregation as a Repeated Game: Learning Algorithms for Efficient Convergence to a Nash Equilibrium
(2013)Carrier aggregation is a key feature of next generation wireless networks to deliver high-bandwidth links. This paper studies carrier aggregation for au- tonomous networks operating in shared spectrum. In our model, ... -
A case for FPGA-based accelerators for energy-efficient motion picture video processing
(SPIE, 2023)In recent years, computing-based video processing workflows have become an integral part of the motion picture industry. These workloads are highly data- and compute-intensive, requiring capable hardware to achieve ... -
Causality considerations for missing data reconstruction in image sequences
(IEEE, 1997)The 3D autoregressive (AR) model with a non-causal support region has been successfully employed in the reconstruction of texture and missing regions in image sequences. This paper discusses the causality considerations ... -
Channel Assignment Based on Routing Decisions (CARD): Traffic-Dependent Topology Control for Multi-Channel Networks
(2009-06)Dynamic spectrum access (DSA) holds the promise for more efficient utilization of the spectrum, while requiring greater cooperation between PHY, MAC, and NET layers to allocate resources and dynamically react to changing ... -
Characterisation of Macro-porous Silicon for Electronic Applications
(SPIE, 2003)Micro-Raman spectroscopy was used in this study for the analysis of the influence of process conditions on the strain and stress in macro-porous layers. As expected, it was found that oxidation results in significant wafer ... -
Characterisation of thin film silicon films deposited by plasma enhanced chemical vapour deposition at 162MHz, using a large area, scalable, multi-tile-electrode plasma source
(2011)Large area (600 ? 720 mm) depositions of hydrogenated microcrystalline silicon (?c-Si:H) have been achieved at high deposition rates using a scalable, multi-tile electrode topology. Depositions have shown local results of ... -
Characterization of Rapid Melt Growth (RMG) Process for High Quality Thin Film Germanium on Insulator
(2012)Germanium is one of the most promising materials for high performance infra-red photovoltaic devices. High quality singlecrystal germanium on insulator structures can be produced by a Rapid Melt Growth process. Experiments ... -
Chirality of an achiral bent-core nematic mesogen observed in planar and homeotropic cells under certain boundary conditions
(2012)It is shown that planar and homeotropic cells under certain boundary conditions containing an achiral bent-core C5 liquid crystalline material show chiral domains of opposite handedness. However such domains are not seen ... -
Classical quantum crossover in magnetic stochastic resonance in uniaxial superparamagnets
(2010)It is shown that the signal-to-noise ratio of the magnetic moment fluctuations in the magnetic stochastic resonance of a quantum uniaxial paramagnet of arbitrary spin value S subjected to a weak probing ac field H(t) = ... -
Classification and representation of semantic content in broadcast tennis videos
(IEEE, 2005)This paper investigates the semantic analysis of broadcast tennis footage. We consider the spatio-temporal behaviour of an object in the footage as being the embodiment of a semantic event. This object is tracked using ... -
Cognitive networks: Adaptation and learning to achieve end-to-end performance objectives
(IEEE, 2006)In this article we advance the idea of a cognitive network, capable of perceiving current network conditions and then planning, learning, and acting according to end-to-end goals. Cognitive networks are motivated by ... -
Cognitive radio and networking research at Virginia Tech
(IEEE, 2009)More than a dozen Wireless @ Virginia Tech faculty are working to address the broad research agenda of cognitive radio and cognitive networks. Our core research team spans the protocol stack from radio and reconfigura ... -
Combinatorial clock auction for OFDMA-based cognitive wireless networks
(IEEE, 2008)This paper presents a novel application of a market-based spectrum assignment mechanism for exploitation by cognitive radio systems. Advances in DSA policy mean that regulators are moving towards a more liberalised ... -
A Combinatorial Optimisation Approach to the Design of Dual Parented Long-Reach Passive Optical Networks
(2011)We present an application focused on the design of resilient long-reach passive optical networks. We specifically consider dual-parented networks whereby each customer must be connected to two metro sites via local exchange ... -
Comment on Submillimeter spectroscopic study of concentrated electrolyte solutions as high density plasma
(American Institute of Physics, 2003)The authors of the title article: (1) contrary to their findings did not fully comprehend that in our paper [Phys. Chem. Chem. Phys., 3, 523 (2001)], the estimated contribution of ions oscillating between the two "reflecting ... -
