Many systems attempt to forecast user navigation in the Internet through the use of past behavior, preferences and environmental factors. Most of these models overlook the possibility that users may have many diverse sets of preferences. For example, the same person may search for information in different ways at night (when they are pursuing their hobbies and interests) as opposed to during th...

Spatial relations among simple features can be used to characterize complex geospatial features. These spatial relations are often represented using linguistic terms such as near, which have inherent vagueness and imprecision. Fuzzy logic can be used to modeling fuzziness of the terms. Once simple features are extracted from remote sensing imagery, degree of satisfaction of spatial relations am...

This paper briefly describes the approach taken to the Author Profiling task at PAN 13. It describes the simple features used, and the origins in thinking around text readability as a mechanism for identification, and the predictive model used which may have beneficially omitted classes, as well as offering commentary on the results obtained.

Techniques for digital image tampering are becoming widespread for the availability of low cost technology in which the image could be easily manipulated. Copy-move forgery is one of the tampering techniques that are frequently used and has recently received significant attention. But the existing methods, including block-matching and key point matching based methods, are not able to be used to...

A system of fundamental frequency analysis and normalisation is described for obtaining pitch data and comparing them across speakers. This system was used for the analysis of English and Spanish speakers' productions in order to compare the realization of accentual focus in the two languages. The system is based on the simultaneous recording of speech and the laryngeal signal. The latter is mo...

The Coastal Aerosol Transport (CAT) model was developed to study the evolution of aerosol particle size distributions and composition in the coastal environment. The model simulates such processes as particle production at the sea surface, mixing of particles through the boundary layer by turbulent diffusion, gravitational settling, and dry deposition. The model is initialized at the shoreline ...

In this report, we first describe the problem that we are dealing with i.e. data dissemination in multi-hop cognitive radio networks. To address this problem, we propose a channel selection strategy named ‘SURF’. We evaluate the proposed channel selection strategy in both single-hop and multi-hop scenarios and compared it with relevant approaches. So far, one technical report and a poster is pu...

Our long term goal is to develop a tested model of optical properties in the surf zone and adjacent nearshore ocean, including the influence of suspended sediment, bubble population and surface foam, to assess how optical properties are related to short term events such as individual breaking wave crests, and to determine how wave-driven surf zone circulation influences spatial distribution of ...

Image completion involves removing unwanted portions of a given photograph. We propose a method of image completion on the Android phone using a small database to search for a matching image. SURF is employed in image matching and image registration. Fast Poisson blending is used to blend the registered database image with the original image.

We present an approach to directly study mutual relationships between audio and video signals for multimedia applications. The presented approach is mathematically based on information theory and is closely related to information theoretic classification. We show that very simple features of the audioresp. video-channel can already contain lots of mutual information between both modalities. The...
