A graph G is called a pairwise compatibility graph (PCG) if there exists an edge weighted tree T and two non-negative real numbers dmin and dmax such that each leaf lu of T corresponds to a vertex u ∈ V and there is an edge (u, v) ∈ E if and only if dmin ≤ dT (lu, lv) ≤ dmax where dT (lu, lv) is the sum of the weights of the edges on the unique path from lu to lv in T . In this paper we analyze...

Strain is an important parameter for assessing the potential impacts resulting from mine subsidence movements. However, strain resulting from mine subsidence is also one of the most difficult parameters to predict accurately. A number of methods can be used to predict strain, from simple empirical relationships, to more complex statistical approaches. This paper looks at some of these predictio...

A graph G = (V, E) is called a pairwise compatibility graph (PCG) if there exists a tree T , a positive edge-weight function w on T , and two non-negative real numbers dmin and dmax, dmin ≤ dmax, such that V coincides with the set of leaves of T , and there is an edge (u, v) ∈ E if and only if dmin ≤ dT,w(u, v) ≤ dmax where dT,w(u, v) is the sum of the weights of the edges on the unique path fr...

This paper describes a Web-based query system for semantically heterogeneous geospatial data. Our goal is to provide DBMS type query capabilities to a proposed statewide land information system. One of the main problems in querying distributed local data sources is the difference in semantics describing the characteristics (attributes) of spatial objects between various jurisdictions. To addres...

In this paper, we explore the interaction between taxation and local public good (LPG) and how it impacts the spatial pattern in the framework of new economic geography (NEG). In the benchmark case of a pure LPG, the system displays a similar location pattern to the existing NEG taxation model, although the tax reduces the market size of manufactured goods. However, when we consider the inheren...

The paper reviews various topics in shape analysis. In particular, matching configurations using regression is emphasized. Connections with general shape spaces and shape distances are discussed. Kendall’s shape space and the affine shape space are considered in particular detail. Matching two configurations and the extension to generalized matching are illustrated with applications in electrop...

Differences between image processing and other disciplines in the definition and the role of shape are explored. Diverse approaches to quantifying shape are reviewed. Attention is drawn to the need for close coupling between image acquisition and shape analysis. An example of the effect of the means of observation on dynamic shape extraction is drawn from linguistics. Current instrumentation fo...

Motions of virtual characters in movies or video games are typically generated by recording actors using motion capturing methods. Animations generated this way often need postprocessing, such as improving the periodicity of cyclic animations or generating entirely new motions by interpolation of existing ones. Furthermore, search and classification of recorded motions becomes more and more imp...

Local scale variations within the same species are common in nature. The shape matching puzzle poses fascinating questions, like how should we measure the discrepancy between a small dog with large ears and a large one with small ears? are there similar geometric structures that are common to an elephant and a giraffe? what is the morphometric similarity between a blue whale and a dolphin? Exis...

â  regional and urban planning instruments contain an extensive range of concepts and methods. these methods are important for understanding the complex identity of cities and the prediction of their future. today majority of planners and urban planning authorities believe that the use of these methods can help us to better understand urban systems and predict their behavior. in this regard the...
