    Investigating the Dimensions of Spatial Language: A Preliminary Study

    No full text
    In order to collect rich data on spatial prepositions, we have created a framework for gathering user annotations in 3D virtual environments. The framework is built using the Blender 3D modelling software and game engine. The framework initially provides two distinct tasks with which our preliminary study was conducted — a Selection Task and a Description Task. In both tasks, participants are given a first person view of a scene which they can navigate using the mouse and keyboard. In the Selection Task participants are given a preposition on screen and asked to select all figure-ground pairs in the scene which fit the preposition. Once they have selected all pairs they believe to be admissible they are shown another preposition and asked to repeat the process. In our preliminary study, we limited this task to ‘in’, ‘inside’, ‘on’, ‘on top of’, ‘against’, ‘over’, ‘under’, ‘above’ and ‘below’. In the Description Task objects are highlighted and participants are able to type in a spatial description of the object. In our preliminary study we asked participants to give descriptions of the object locations using a definite description, in the format figure + preposition + ground e.g. ‘the guitar by the bookshelf’. We also allowed the use of multiple prepositions if the participant deemed it necessary e.g. ‘the cup on the table near the lamp’. To make the annotations more relevant to our research we asked participants to only use the prepositions in the Selection Task plus ‘to the right of’, ‘to the left of’, ‘in front of’, ‘behind’, ‘near’, ‘next to’, ‘at’. The current dataset is from a session we hosted in one of our computing labs where we invited participants from across the university campus to take part. We asked participants to complete either the Selection Task or Description Task in one of our scenes. Participants were given a brief introduction to the study and instructions on how to complete the given task along with explanations of key terminology. All participants were asked to create annotations for ten minutes. 23 native English speakers participated, of which 13 performed the Selection Task and 10 performed the Description Tas

    Country Houses: Data Showing the Causes of Decline of Country Houses in Yorkshire and Surrey.

    No full text
    The data consists of a spreadsheet containing the data of 297 county houses that have been demolished in Yorkshire and Surrey, England. Specifically, the name, location, decade of demolition and reason for demolition. This data was used to create maps on which each lost house was plotted and graphs outlining the post prominent causes for decline. These figures are included within a dissertation researching the causes for decline of country houses in the twentieth century

    Dataset associated with 'Silver-based surface plasmon waveguide for terahertz quantum cascade lasers'

    Get PDF
    This dataset contains the raw data of the publication about silver-based waveguide for THz QCLs, including waveguide analysis and experimental characteristics. Silver-based waveguides for terahertz-frequency quantum cascade lasers (THz QCLs) have been investigated, and good agreement is found between the waveguide analysis and the experimental characteristics. In the waveguide analysis, the dielectric constants of metal films are calculated based on the Drude model, in which the damping frequencies are extracted from the measured dc resistivities. The simulation shows that silver waveguides yield lower losses for THz QCLs across all practical operating temperatures and frequencies than their gold- and copper-based counterparts, both in surface-plasmon and double-metal waveguide geometries. Experimentally, we demonstrate higher operating temperatures and greater output powers when compared to identical devices fabricated with gold-based surface plasmon waveguides. The magnitude of the improvements is found to be dependent on the active-region design, such as the radiative diagonality and the doping concentration. Our results indicate that silver-based waveguides can potentially enable THz QCLs to operate at high temperature
