This paper demonstrates the possibilities of a Geographical Information System (GIS) for investigating and explicating spatial variation short-range viewshed aesthetic appeal in World Heritage coastal dune forest area. The study pursues following objectives: (1) develop trial GIS-based algorithm computing Aesthetic Appeal Index Short-Range Viewshed (?); (2) deliver an output map showing compute...

Image retrieval of landscape photographs requires accurate annotation using multi-faceted descriptions relating to the subject and content of the photograph. The subject of such photographs is dominantly the terrain and spatial objects visible from the photographer’s viewpoint. While some spatial objects in the background may be obscured by foreground vegetation, other visible spatial objects b...

In archaeological research, visibility analysis is usually based on binary viewshed maps. However, Digital Elevation Models inherently contain errors due to inaccuracies in the original topographic data and the data structure used. Therefore the binary classification will be subject to an unknown amount of error. It would be more appropriate to use a method for visibility calculation which allo...

UNLABELLED Many DNA functional motifs tend to accumulate or cluster at specific gene locations. These locations can be detected, in a group of gene sequences, as high frequency 'peaks' with respect to a reference position, such as the transcription start site (TSS). We have developed a web tool for the identification of regions containing significant motif peaks. We show, by using different yea...

Finding and identifying characteristic or meaningful image sequences in a continuous video stream is a challenging task with many applications. This paper presents a new and efficient approach to these temporal segmentation and classification problems based on Hidden Markov Models (HMMs). The basic principle consists in continuously observing the output scores of the HMMs at every time step. Pe...

Samples were collected monthly at four fixed stations in Mida creek from May 1996 to April 1997, in order to determine the species composition, abundance and diversity of phytoplankton and zooplankton collected with 20and 332-μm mesh size plankton nets respectively. Sampling also included measurement of salinity and temperature. Peaks in phytoplankton abundance occurred in May and January, foll...

A description of the light curves of microlensed Type Ia supernovae (SNe Ia) as extended and expanding sources is presented. We give examples of what microlensing by stellar-mass Chang-Refsdal lenses can do to a small percentage of supernova light curves. We find that in addition to overall brightening, significant changes in light–curve shapes can also occur. Peaks can be distorted, plateaus c...
