Analysis of amorphous indium-gallium-zinc-oxide thin-film transistor contact metal
(AIP Publishing LLCApplied Physics Letters, 2013-04-15)
It is widely reported that threshold voltage and on-state current of amorphous indiumgallium-
zinc-oxide bottom-gate thin-film transistors is strongly influenced by the choice of
source/drain contact metal. Electrical ...
Gas-sensitive holographic sensors
(University of CambridgeDepartment of Chemical Engineering and BiotechnologyInstitute of Biotechnology, 2013-04-16)
Holographic sensors are photonic layered structures contained in analyte sensitive lms that upon illumination produce monochromatic reflections (λ). The present work reports the fabrication of oxygen and ammonia sensors ...
Automatic induction of verb classes using clustering
(University of CambridgeFaculty of Computer Science and TechnologyComputer Laboratory, 2013-04-30)
Verb classifications have attracted a great deal of interest in both linguistics and natural language processing (NLP). They have proved useful for important tasks and applications, including e.g. computational lexicography, ...
'You can't just hit a button’: an ethnographic study of strategies to repurpose data from advanced clinical information systems for clinical process improvement
(BMC Medicine, 2013-04)
Abstract Background Current policies encourage healthcare institutions to acquire clinical information systems (CIS) so that captured data can be used for secondary purposes, including clinical process improvement. Such ...
Colour videos with depth : acquisition, processing and evaluation
(University of Cambridge, 2012-03-06)
The human visual system lets us perceive the world around us in three dimensions
by integrating evidence from depth cues into a coherent visual model of the world. The equivalent in computer vision and computer graphics ...
Autoregressive models for statistical parametric speech synthesis
(IEEE (Institute of Electrical and Electronics Engineers), 2013-03)
We propose using the autoregressive hidden Markov model (HMM) for speech synthesis. The autoregressive HMM uses the same model for parameter estimation and synthesis in a consistent way, in contrast to the standard approach ...
The effect of using normalized models in statistical speech synthesis
(ISCA (International Speech Communication Association), 2011-08-27)
The standard approach to HMM-based speech synthesis is inconsistent in the enforcement of the deterministic constraints between static and dynamic features. The trajectory HMM and autoregressive HMM have been proposed as ...
Fast, low-artifact speech synthesis considering global variance
(IEEE (Institute of Electrical and Electronics Engineers), 2013-05-27)
Speech parameter generation considering global variance (GV generation) is widely acknowledged to dramatically improve the quality of synthetic speech generated by HMM-based systems. However it is slower and has higher ...
Flexural Fatigue Performance of CFRP Prestressed Concrete Poles
(Multi-Science PublishingAdvances in Structural Engineering, 2012-04-24)
Carbon fibre reinforced polymer (CFRP) prestressed concrete poles offer a durable, light-weight alternative to conventional steel-reinforced or prestressed concrete poles. In particular, the corrosion resistance of the ...
Precracked RC T-beams Repaired in Shear with Externally Bonded CFRP Sheets
(American Concrete InstituteACI Structural Journal, 2012-03-01)
This study investigates the structural behavior of precracked reinforced concrete (RC) T-beams strengthened in shear with externally bonded carbon fiber-reinforced polymer (CFRP) sheets. It reports on seven tests on ...
