Accompanying the mounting detections of planets orbiting white dwarfs and giant stars are questions about their physical history evolution, particularly regarding detectability atmospheres potential for habitability. Here we determine how size planetary magnetospheres evolve over time from end main sequence through to dwarf phase due violent winds red asymptotic branch stars. By using a semiana...

In recent years, many approaches have been exploited for automatic road extraction. Most of these approaches are based on edge detection algorithms. In this paper, a new object-based approach for automatic extraction of main roads in large scale imagemaps is proposed. The gray-scale imagemap is converted to a simplified imagemap using Gray scale Morphological Algorithms (GMA). At this point, th...

This study evaluates the impact of the 65-mph speed limit on traffic safety. Using data for the years 1981 to 1995 for all 50 states, a pooled time series analysis is conducted. Separate models are estimated for state fatality rates on four categories of roads: rural interstate highways, rural noninterstate roads, all roads except for rural interstate highways, and all roads. It is reported tha...

Background: Every year many people are killed or injured in road accidents. The first step in planning to reduce accidents is to identify the causes of accidents. This study aimed to investigate and identify the causes and factors affecting the incidence and the severity of road accidents as a major issue in Ilam Province, Iran. Materials and Methods: This research is a descriptive study with ...

We provide full parameters and additional qualitative results of our curved symmetry detector (SRFSym) and symmetryconstrained segmentation (SymSegGC) over all four datasets: 1) SYMMAX-300 (SYMSEG-300), 2) BSD-Parts, 3) WHD and 4) NY-roads, described in the main paper.

Crystallographic Nexus CD-ROMs, containing a range of free crystallographic software for single-crystal and powder diffraction available on the Internet, have been distributed on request since 1996. The free CD is made in the form of a ;virtual Internet' with the main intent of benefiting crystallographers with inadequate Internet access. The IUCr funds an annual/biennial update which is distri...

OBJECTIVE This study sought to extend previous analyses of food insecurity in Montreal by examining the relationship between neighbourhood sociodemographic and urban form variables and sources of food both unhealthful (fast-food outlets, FFO) and healthful (stores selling fruits and vegetables, FVS). METHODS Densities of FFO and FVS were computed for 862 Census tract areas (CTA) (defined as c...
