We start by characterizing the role of a set of invariant mappings within a semantic framework for metaphor interpretation. Such rules are defaults and have previously been identified by our group as invariant mappings adjuncts to any conceptual metaphor. We provide a formal description of several invariant mappings that transfer information such as causation and event degrees, and discuss some...

The purpose of this communication is to investigate the usefulness of the differential flatness control approach to solve the trajectory tracking problem for a four rotor aircraft. After introducing simplifying assumptions, the flight dynamics equations for the four rotor aircraft are considered. A trajectory tracking control structure based on a two layer non linear approach is then proposed. ...

Although high levels of population mobility are often viewed as a problem at the neighbourhood level we know relatively little about what makes some neighbourhoods more mobile than others. The main question in this paper is to what extent differences in out-mobility between neighbourhoods can be explained by differences in the share of mobile residents, or whether other neighbourhood characteri...

Difference in differences (DID) require that the treatment rate is equal to 0% in the control group and during period 0 (no “always takers”) and to 100% in the treatment group in period 1 (no “never takers”). Sometimes, treatment rate increases more in the treatment than in the control group but there are never or always takers. This paper derives identification results applying to such setting...

We illustrate how the use of metaphorical views for reasoning with metaphor requires the mapping of information such as event shape, event rate and mental/emotional states from the source domain to the target domain. Such mappings are domain-independent and can be implemented by means of rules we call View Neutral Mapping Adjuncts (VNMAs). We give a list of the main VNMAs that appear to be requ...

This document describes a study of metaphor annotation that was carried out as part of the ATT-Meta project. The study lead to a number of results about metaphor and how it is signalled that are reported elsewhere (e.g. Wallington et al 2003a, Wallington et al 2003b). It also resulted in a public database of metaphorical views (http://www.cs.bham.ac.uk/research/attmeta/DatabankDCA/index.html). ...

We study the coarsening observed in spiral-mode growth of thin films. The high-temperature superconductor YBa2Cu3O7−δ provides a suitable model system. The density of spirals at the surface decreases as the film gets thicker. In other words, the grain size coarsens with distance from the substrate. We propose a simple mechanism for this coarsening, based on geometrical competition of spirals wi...

Male oriental fruit moths do not fly upwind in a continuous uniform cloud of pheromone, but readily do so when the cloud is pulsed at 1 or 0 51s or when a plume from a point source of pheromone is placed within the continuous cloud It is suggested that males of moth species that require such fluctuating pheromone stimulation for upwind flight will normally receive it from a filamentous, point-s...

A method to efficiently generate a complete aerodynamic description for projectile flight dynamic modeling is described. At the core of the method is an unsteady, time accurate computational fluid dynamics simulation that is tightly coupled to a rigid body dynamics simulation. A set of n short time snippets of simulated projectile motion at m different Mach numbers is computed and employed as b...
