Switching and memory characteristics of thin films of an ambipolar organic compound: effects of device processing and electrode materials (2014)
Journal Article
Lee, M., Pearson, C., Moon, T., Fisher, A., & Petty, M. (2014). Switching and memory characteristics of thin films of an ambipolar organic compound: effects of device processing and electrode materials. Journal of Physics D: Applied Physics, 47(48), https://doi.org/10.1088/0022-3727/47/48/485103

We report on the effects of device processing conditions, and of changing the electrode materials, on the switching and negative differential resistance (NDR) behaviour of metal/organic thin film/metal structures. The organic material was an ambipola... Read More about Switching and memory characteristics of thin films of an ambipolar organic compound: effects of device processing and electrode materials.

A Comparison of Features for Regression-based Driver Head Pose Estimation under Varying Illumination Conditions (2014)
Presentation / Conference Contribution
Walger, D., Breckon, T., Gaszczak, A., & Popham, T. (2014, November). A Comparison of Features for Regression-based Driver Head Pose Estimation under Varying Illumination Conditions. Presented at Proc. International Workshop on Computational Intelligence for Multimedia Understanding

Head pose estimation provides key information about driver activity and awareness. Prior comparative studies are limited to temporally consistent illumination conditions under the assumption of brightness constancy. By contrast the illumination condi...

Using Compressed Audio-visual Words for Multi-modal Scene Classification (2014)
Presentation / Conference Contribution
Kurcius, J., & Breckon, T. (2014, November). Using Compressed Audio-visual Words for Multi-modal Scene Classification. Presented at Proc. International Workshop on Computational Intelligence for Multimedia Understanding

We present a novel approach to scene classification using combined audio signal and video image features and compare this methodology to scene classification results using each modality in isolation. Each modality is represented using summary feature... Read More about Using Compressed Audio-visual Words for Multi-modal Scene Classification.

A fully automatic polygon scaled boundary finite element method for modelling crack propagation (2014)
Journal Article
Dai, S., Augarde, C., Du, C., & Chen, D. (2015). A fully automatic polygon scaled boundary finite element method for modelling crack propagation. Engineering Fracture Mechanics, 133, 163-178. https://doi.org/10.1016/j.engfracmech.2014.11.011

An automatic crack propagation remeshing procedure using the polygon scaled boundary FEM is presented. The remeshing algorithm, developed to model any arbitrary shape, is simple yet flexible because only minimal changes are made to the global mesh in...

Rectennas for Thermal-Energy Conversion (2014)
Presentation / Conference Contribution
Pan, Y., Powell, C., & Balocco, C. (2014, September). Rectennas for Thermal-Energy Conversion. Presented at 39th International Conference on Infrared, Millimeter, and THz Waves, Tucson, AZ, USA

We demonstrated the conversion of thermal energy in the form of far- and mid-infrared using a micro rectenna, consisting of a spiral antenna coupled to an ultra-fast nanodiode, the so-called self-switching device (SSD). A maximum efficiency of 0.02 %... Read More about Rectennas for Thermal-Energy Conversion.

Compositional tuning of atomic layer deposited MgZnO for thin film transistors (2014)
Journal Article
Wrench, J., Brunell, I., Chalker, P., Jin, J., Shaw, A., Mitrovic, I., & Hall, S. (2014). Compositional tuning of atomic layer deposited MgZnO for thin film transistors. Applied Physics Letters, 105(20), Article 202109. https://doi.org/10.1063/1.4902389

Thin film transistors (TFTs) have been fabricated using magnesium zinc oxide (MgZnO) layers deposited by atomic layer deposition at 200 °C. The composition of the MgZnO is systematically modified by varying the ratio of MgO and ZnO deposition cycles....
