The Nasca lines or geoglyphs in southern Peru are known as one of archaeology's greatest mysteries. Since the 1980s, however, new approaches have helped to better understand their function and meaning. The recent photogrammetric recording of 1 500 geoglyphs in the vicinity ofPalpa enabled for the first time a GIS-based analysis. Geoglyph visibility is one of their most discussed traits. While m...

We present an approach to determine the credibility of content provided within a visual VGI source such as Flickr. We propose analysing the variability of selected user and photo metadata of geotagged Flickr photos with the location correctness of these images, which is our reference quality measure. These observed user and photo metadata can help to infer the credibility of contributors.

Abstract. In this paper we study the shape of least-energy solutions to the quasilinear problem ε∆mu−u + f (u) = 0 with homogeneous Neumann boundary condition. We use an intrinsic variation method to show that as ε → 0, the global maximum point Pε of least-energy solutions goes to a point on the boundary ∂Ω at the rate of o(ε) and this point on the boundary approaches to a point where the mean ...

Descents, Peaks, and P -partitions A dissertation presented to the Faculty of the Graduate School of Arts and Sciences of Brandeis University, Waltham, Massachusetts by T. Kyle Petersen We use a variation on Richard Stanley’s P -partitions to study “Eulerian” descent subalgebras of the group algebra of the symmetric group and of the hyperoctahedral group. In each case we give explicit structure...

Since the published MS-GFDB did not support variable PTMs at the time that this research was carried out, both MS-GFDB and PEAKS DB were run without specifying any variable PTMs. The other parameters, including the fixed PTMs, remained the same as described in the results section. The results are shown in Figure S2 for CID and Figure S3 for ETD datasets, respectively. Note that the removal of t...

An image may be decomposed as a difference between an image of peaks and an image of wells. Applying a morphological operator to these two components before reconstructing a final image produces interesting filters for grey tone or binary images. This decomposition depends upon the point of view from where the image is considered.
