On the need for fine-grained analysis of Gender versus Commenting Behaviour in MOOCs (2018)
Presentation / Conference Contribution

Stereotyping is the first type of adaptation ever proposed. However, the early systems have never dealt with the numbers of learners that current Massive Open Online Courses (MOOCs) provide. Thus, the umbrella question that this work tackles is if le... Read More about On the need for fine-grained analysis of Gender versus Commenting Behaviour in MOOCs.

Application of fluidic curtains to turbine rotor tip seal geometries. (2018)
Presentation / Conference Contribution

Fluidic curtain sealing has recently been shown to offer strong potential especially when a combination of fluidic curtain and a conventional labyrinth seal is used. A series of fundamental dimensionless ratios have been proposed and the design space... Read More about Application of fluidic curtains to turbine rotor tip seal geometries..

PyCoTools: a Python toolbox for COPASI (2018)
Journal Article

Motivation COPASI is an open source software package for constructing, simulating and analyzing dynamic models of biochemical networks. COPASI is primarily intended to be used with a graphical user interface but often it is desirable to be able to ac... Read More about PyCoTools: a Python toolbox for COPASI.

Low-Voltage Solution-Processed Hybrid Light-Emitting Transistors (2018)
Journal Article

We report the development of low operating voltages in inorganic–organic hybrid light-emitting transistors (HLETs) based on a solution-processed ZrOx gate dielectric and a hybrid multilayer channel consisting of the heterojunction In2O3/ZnO and the o...

Joint effects of weather and interspecific competition on foraging behaviour and survival of a mountain herbivore (2018)
Journal Article

Weather variations have the potential to influence species interactions, although effects on competitive interactions between species are poorly known. Both weather and competition can influence foraging behavior and survival of herbivores during nur...

Short Channel Effect of Solution-Processed ZnO Thin Film Transistors: Optimization for Photolithographic Process (2018)
Journal Article

A photolithographic process for the fabrication of short channel solution-processed zinc oxide transistors (ZnO TFTs) was optimized. To avoid damage to the ZnO film by the photolithography, a bottom gate, bottom contact (BG-BC) device structure was a...

The Effect of Humidity on Microwave Characteristics of 2 Screen Printed Paper-Based Electronics (2018)
Journal Article

This paper addresses one of the key issues in using paper electronics at microwave frequencies. As paper is hygroscopic, the varying moisture content can lead to differing dielectric and even conductive properties of paper electronics and must be tak...

Creating Complex Optical Longitudinal Polarization Structures (2018)
Journal Article

In this Letter, we show that it is possible to structure the longitudinal polarization component of light. We illustrate our approach by demonstrating linked and knotted longitudinal vortex lines acquired upon nonparaxially propagating a tightly focu...

Fast DEM collision checks on multicore nodes (2018)
Presentation / Conference Contribution

Many particle simulations today rely on spherical or analytical particle shape descriptions. They find non-spherical, triangulated particle models computationally infeasible due to expensive collision detections. We propose a hybrid collision detecti...
