Dynamic polarisation reveals differential steady-state stabilisation and capacitive-like behaviour in microbial fuel cells (2013)
Journal Article

In this paper we present several preliminary results produced with a purposely-designed external-resistor (R ext ) sweeping tool for microbial fuel cells (MFCs). Fast sampling rates show that MFCs exhibit differential steady-state stabilisation behav...

A variable compliance, soft gripper (2013)
Journal Article

Autonomous grasping is an important but challenging task and has therefore been intensively addressed by the robotics community. One of the important issues is the ability of the grasping device to accommodate varying object shapes in order to form a... Read More about A variable compliance, soft gripper.

Non-existence of local solutions for semilinear heat equations of Osgood type (2013)
Journal Article

We establish non-existence results for the Cauchy problem of some semilinear heat equations with non-negative initial data and locally Lipschitz, non-negative source term f. Global (in time) solutions of the scalar ODE v;=f(v) exist for v(0)>0 if and... Read More about Non-existence of local solutions for semilinear heat equations of Osgood type.

The effect of billets extruded by a curved and flat-face die on the semisolid characteristics and tensile properties of thixoformed products (2013)
Journal Article

In this study, A356 aluminum billets in different extruded states are used as feedstock for the thixoforming. The extrusion billets were fabricated by a hot extrusion process through a flat-face and a curved die. After the induction reheating of the...

Landmarks and ant search strategies after interrupted tandem runs (2013)
Journal Article

© 2014. Published by The Company of Biologists Ltd. During a tandem run, a single leading ant recruits a single follower to an important resource such as a new nest. To examine this process, we used a motorized gantry, which has not previously been u... Read More about Landmarks and ant search strategies after interrupted tandem runs.

Processing of low-carbon cast steels for offshore structural applications (2013)
Journal Article

Cast steels with carbon contents of approximately 0.05%, 0.1%, and 0.2% (low-carbon steels) were processed. The investigated steels were first cast. Fully lath martensite was obtained after austenitization and water quenching of the cast steels. The... Read More about Processing of low-carbon cast steels for offshore structural applications.

U-shaped energy loss curves utilization for distributed generation optimization in distribution networks (2013)
Journal Article

We propose novel techniques to find the optimal location, size, and power factor of distributed generation (DG) to achieve the maximum loss reduction for distribution networks. Determining the optimal DG location and size is achieved simultaneously u... Read More about U-shaped energy loss curves utilization for distributed generation optimization in distribution networks.

Nest-seeking rock ants (Temnothorax albipennis) trade off sediment packing density and structural integrity for ease of cavity excavation (2013)
Journal Article

We investigated excavation and nest site choice across sediment-filled cavities in the ant Temnothorax albipennis. Colonies were presented with sediment-filled cavities, covering a spectrum from ones that should be quick to excavate but will form a w...

Improvement of spin flight test quality by evaluation of measured data (2013)
Presentation / Conference Contribution

The aim is to equip an aeroplane with different sensor systems to acquire data from spin flight tests. One sensor system contains an acceleration sensor and electronic gyroscopes to determine the attitude and position and another sensor system contai...

Sliding mode hybrid impedance control of robot manipulators interacting with unknown environments using VSMRC method (2013)
Presentation / Conference Contribution

In the present paper, the objective of hybrid impedance control is specified and a robust hybrid impedance control approach is proposed. Based on the concept of hybrid control, the task space is decomposed into position and force controlled subspaces...
