• My main concern with the paper is that whilst a range of options are investigated for measuring inconsistency in prioritized knowledge bases, each of which is significantly influenced by the measures proposed in the literature for flat knowledge bases, there is a lack of a unified framework for comparing the different options. The results only show some differences between them in terms of so...

We use trajectory based techniques to perform location independent behaviour recognition on an unmanned underwater vehicle. Unmanned vehicles have applications in both surveillance and structural inspection, but require robust, location independent behaviour recognition. Previous research has used GPS or location based states that tie model parameters to specific locations, and have rarely cons...

A TRNSYS component (Type 262) has been written to simulate a concentrating PV/Thermal collector. The component is based on a dynamic model of a concentrating PV/Thermal collector, which includes thermal capacitance effects, and detailed equations describing the temperature dependent energy flow between the collector and surroundings. The CHAPS system, a 30x concentration parabolic trough PV/The...

We report the design and implementation of a callgraph profiler for GNU Octave, a numerical computing platform. GNU Octave simplifies matrix computation for use in modeling or simulation. Our work provides a callgraph profiler, which is an improvement on the flat profiler. We elaborate design constraints of building a profiler for numerical computation, and benchmark the profiler by comparing i...

In the present work, a prototype of a new type of solar collectors, which called Direct Absorption Solar Collector, was built and its thermal performance is experimentally compared with conventional flat plate solar collector under transient and steady state conditions. Different volume fractions of multi wall carbon nanotubes in water and ethylene glycol mixture (70%:30% in volume) were used a...

Until now all well-studied dark energy models proposed have very large Compton wavelengths, λc > 100Mpc at all time and hence show no clustering on small scales. Evidence against this would disfavour both ΛCDM and quintessence. We show however, that large λc is actually favoured by current CMB, LSS and SN1a data by comparing quintessence with a condensate scenario with the same background dynam...

The attenuation of a plane acoustic wave incident on a flat impedance surface in a sheared and viscous fluid is investigated numerically and asymptotically. Predictions of various boundary models of impedance surfaces in shear flow are tested by comparing their predicted reflection coefficient. It is found that viscosity has a significant effect, reducing the reflection of upstream propagating ...

Until now all well-studied dark energy models proposed have very large Compton wavelengths, λc > 100Mpc at all time and hence show no clustering on small scales. Evidence against this would disfavour both ΛCDM and quintessence. We show however, that large λc is actually slightly favoured by current CMB, LSS and SN1a data by comparing quintessence with a condensate scenario with the same backgro...

We derive source-free Maxwell-like equations in flat spacetime for any helicity j by comparing the transformation properties of the 2(2j + 1) states that carry the manifestly covariant representations of the inhomogeneous Lorentz group with the transformation properties of the two helicity j states that carry the irreducible representations of this group. The set of constraints so derived invol...

Hierarchical or nested annotation of linguistic data often co-exists with simpler non-hierarchical or flat counterparts, a classic example being that of annotations used for parsing and chunking. In this work, we propose a general strategy for comparing across these two schemes of annotation using the concept of entailment that formalizes a correspondence between them. We use crowdsourcing to o...
