Estimating Epipolar Geometry With The Use of a Camera Mounted Orientation Sensor
Context: Image processing and computer vision are rapidly becoming more and more commonplace, and the amount of information about a scene, such as 3D geometry, that can be obtained from an image, or multiple images of the scene is steadily increasing due to increasing resolutions and availability of imaging sensors, and an active research community. In parallel, advances in hardware design and manufacturing are allowing for devices such as gyroscopes, accelerometers and magnetometers and GPS receivers to be included alongside imaging devices at a consumer level.
Aims: This work aims to investigate the use of orientation sensors in the field of computer vision as sources of data to aid with image processing and the determination of a scene’s geometry, in particular, the epipolar geometry of a pair of images - and devises a hybrid methodology from two sets of previous works in order to exploit the information available from orientation sensors alongside data gathered from image processing techniques.
Method: A readily available consumer-level orientation sensor was used alongside a digital camera to capture images of a set of scenes and record the orientation of the camera. The fundamental matrix of these pairs of images was calculated using a variety of techniques - both incorporating data from the orientation sensor and excluding its use
Results: Some methodologies could not produce an acceptable result for the Fundamental Matrix on certain image pairs, however, a method described in the literature that used an orientation sensor always produced a result - however in cases where the hybrid or purely computer vision methods also produced a result - this was found to be the least accurate.
Conclusion: Results from this work show that the use of an orientation sensor to capture information alongside an imaging device can be used to improve both the accuracy and reliability of calculations of the scene’s geometry - however noise from the orientation sensor can limit this accuracy and further research would be needed to determine the magnitude of this problem and methods of mitigation
Bending and Breathing Modes of the Galactic Disk
We explore the hypothesis that a passing satellite or dark matter subhalo has
excited coherent oscillations of the Milky Way's stellar disk in the direction
perpendicular to the Galactic midplane. This work is motivated by recent
observations of spatially dependent bulk vertical motions within ~ kpc of the
Sun. A satellite can transfer a fraction of its orbital energy to the disk
stars as it plunges through the Galactic midplane thereby heating and
thickening the disk. Bulk motions arise during the early stages of such an
event when the disk is still in an unrelaxed state. We present simple toy-model
calculations and simulations of disk-satellite interactions, which show that
the response of the disk depends on the relative velocity of the satellite.
When the component of the satellite's velocity perpendicular to the disk is
small compared with that of the stars, the perturbation is predominantly a
bending mode. Conversely, breathing and higher order modes are excited when the
vertical velocity of the satellite is larger than that of the stars. We argue
that the compression and rarefaction motions seen in three different surveys
are in fact breathing mode perturbations of the Galactic disk.Comment: 12 pages, 12 figure
Alternative vs. Traditional News: A Content Analysis of News Coverage of the 10th Anniversary of Sept. 11
The researcher sought to understand the differences in framing used by alternative media outlets and traditional or mainstream media outlets. A sampling of articles about the 10th anniversary of the Sept. 11, 2001, terrorist attacks was used from alternative and traditional media publications to conduct this study. These articles were analyzed by a software program to determine themes and concepts within both data sets. The analysis revealed traditional media was less varied in themes than was alternative media, with the latter clearly showing an effort to be. Traditional media was found to provide routine coverage of commemorative services and very little critical analysis. Further highlighting the differences in the 2 media paradigms was the use of profanity in alternative media, which was discovered by using the find function available with word processing software
An Exploration with Technology Acceptance Modelling intohow PSD2 Could Improve User Interactions in Personal Finance
A two-fold study attempting to perceive the possible innovations possible thanks to the upcoming Payment Services Directive II using a newly extended adaptation of the Technology Acceptance Model with an aspect of Social Intention, the SITAM.The research successfully highlights the legislation's consequential opportunities, and crafts a multi-banking application with price comparison integration with high user intention to install, lending itself to being developed into a full public release in the future. The SITAM meanwhile gives a new approach to planning and developing software to theoretically maximise adoption at every stage of the lifecycle, offering a contemporary method of categorising survey participants into innovation groups in order to treat feedback differently to match the target market

University for the Creative Arts staff research 2011
This publication brings together a selection of the University’s current research. The contributions foreground areas of research strength including still and moving image research, applied arts and crafts, as well as emerging fields of investigations such as design and architecture. It also maps thematic concerns across disciplinary areas that focus on models and processes of creative practice, value formations and processes of identification through art and artefacts as well as cross-cultural connectivity.

Popis slatkovodnih riba Jugoslavije
Over the past four years, genome-wide studies have uncovered numerous examples of structural variation in the human genome. This includes structural variation that changes copy number, such as deletion and duplication, and structural variation that does not change copy number, such as orientation and positional polymorphism. One region that contains all these types of variation spans the chromosome band 8p23.1. This region has been studied in some depth, and the focus of this review is to examine our current understanding of the variation of this region. We also consider whether this region is a good model for other structurally variable regions in the genome and what the implications of this variation are for clinical studies. Finally, we discuss the bioinformatics challenges raised, discuss the evolution of the region, and suggest some future priorities for structural variation researc
