A reactivated cave system induces rapidly developing cover-collapse sinkholes in Tasmania, Australia
vspace{0.2cm}In this paper, we design a data structure for the following problem. Let $pi$ be an $x$-monotone trajectory with $n$ vertices in the plane and $epsilon >0$. We show how to preprocess $pi$ and $epsilon$ into a data structure such that for any horizontal query segment $Q$ in the plane, one can quickly determine the minimal continuous fraction of $pi$ whose Fr{'e}chet and Hausdo...

This paper is concerned with computing graph edit distance. One of the criticisms that can be leveled at existing methods for computing graph edit distance is that it lacks the formality and rigour of the computation of string edit distance. Hence, our aim is to convert graphs to string sequences so that standard string edit distance techniques can be used. To do this we use graph spectral seri...
the aim of the current study was to investigate the perceived psychic distance of potentialtourists in relation to iran as a tourism destination. the concept of psychic distance refersto perceived similarities/ differences between specific destination and tourist's homecountry. the members of couch-surfing virtual community participated in this study. thestatistical data were collected by conve...
Introduction. As a result of the conducted route reconnaissance and geological engineering surveys, data about development pattern exogenous processes at site adjoining city Ufa were obtained. This region is well studied due to extensively developed karst. Although landslides are less prevalent here, their frequently connected with karst intensification. Landslides, formed in sites sinkholes to...
Watersheds are changed positively or negatively as biotic and abiotic factors in natural circumstances impact them. Landslides, as a physical factor, one of the negative consequences on these catchments. Masoleh watershed, in North of Iran, is one of the susceptible areas to explode the natural landslides. In other to landslide hazard zonation, the Dempster-Shafer model is which is used has 14 ...
this study was performed with objective land cover change prediction (forest, agriculture, residential and orchard) using logistic regression and markov chain in the gis environment in east of mazandaran province. land cover change detected using satellite imageries belonging to the years 1987 and 2001. transition potential modeling was conducted using a logistic regression. seven variables (de...
the main objective of this study was to arak city zoning geomorphological parameters of the model using fuzzy logic. in order to realize these objectives, 10 parameters including of height, distance from fault, distance from the main channel, distance from sub-channel, distance from road, slope percent, distance from settlements, terrain type, erosion potential and seismic vulnerability in the ...
