landscape metrics quantifies structural features of the landscape. one of the advantages of these metrics is a possibility to use them in fast cumulative assessment of the development activities in the environment. in this paper, the cumulative effects of road network expansion on the tree cover of gorgan, kordkuy, aliabad townships in golestan province were investigated. to prepare the require...

BACKGROUND Several methodological approaches have been used to estimate distance in health service research. In this study, focusing on cardiac catheterization services, Euclidean, Manhattan, and the less widely known Minkowski distance metrics are used to estimate distances from patient residence to hospital. Distance metrics typically produce less accurate estimates than actual measurements, ...

In this paper, a follow-up of [1, 2], we continue to study ternary Hamming spaces Tn, where T = f0; 1; 2g, and their generators. In particular, we are interested in the computational complexity of the generation of all vectors with respect to a speci c generator G Tn. We consider several parameters, i.e., depth and load, which provide alternative ways to measure the computational e ort required...

Over the last three years, the Northeast Parallel Architectures Center at Syracuse University, together with Jackson State University and a number of other academic and DoD partners have conducted a pilot project in distance education, using networkbased TANGO Interactive collaboration tool to deliver semester-long academic credit courses in a synchronous (real-time) fashion. This report summar...

Fog is a challenging problem for road safety. To estimate the fog density and estimate the meteorological visibility distance, some attempts using an in-vehicle cameras are being developed. To complete the notion of meteorological visibility, we propose to estimate the distance to the most distant visible object belonging to the road surface. We call this distance the mobilized visibility dista...

landslides and slope instabilities are major hazards for human activities often causing economiclosses and property damages. sikan river basin (ilam province) due to the topography, tectonic,lithology, and climate has enough potential for occurrence of this phenomenon. the objectives of thisstudy were to determine effective parameters controlling the landslide occurrence and to preparezonation ...

The recent advances in computer visualization methods have made it possible to exploit the possibility of applying scientific visualization methods in critical research areas in the field of transportation engineering. In this paper we develop new visualization methods for road design and safety. Typically, roads are designed by combining horizontal and vertical roadway alignments, to allow for...
