I n this paper, we present a new snake-based method to delineate contours where the m e r has to specify only the two distant end points without having to supply an almost complete polygonal approximation. W e achieve much better convergence properties than those of traditional snakes by propagating the image information along the curve from both end points towards its center. W e use our new m...
fragmentation, or breaking apart of habitats, is one of the major causes of decline in biological diversity. mature ecosystems, especially dense forests are very sensitive to this phenomenon and roads are one of the major causes of fragmentation in forest landscapes. present investigation aims to trace landscape fragmentation in dense forests of golestan national park in northeast of iran betw...
To highlight the advantages of autonomous vehicles (AVs) in modern traffic, it is necessary to investigate sensing requirement parameters road environment during vehicle braking process. Based on texture information obtained using a field measurement, model an AV was built Simulink and ride comfort under typical scenarios analyzed CarSim/Simulink co-simulation. The results showed that proposed ...
The aim of present research is landslide hazard zoning using Bayesian theory in a part of Golestan province. For this purpose, landslides inventory map was created by landslide locations of landslide database (392 landslide locations). Then, the maps of effective parameters in landslide such as slope degree, aspect, altitude, slope curvature, geology, land use, distance of drainage, distance of...
The aim of current research is to assess of landslide susceptibility in the Khalkhal Township, southern Ardabil using an ensemble and new method namely Bayesian and logistic regression (BT-LR) models. At first, landslide inventory map was prepared and then effective factors on landslide occurrence were identified. These factors are slope degree, plan curvature, slope aspect, elevation, landuse,...
Landslide as a natural hazard is very dangerous especially in mountainous areas that result in loss of human life and property around the world. Iran is always exposed to landslide hazard especially in the north and west because of climatic and topographic conditions. The aim of this research is prioritization of landslide-conditioning factors and its landslide susceptibility mapping in the par...
In recent decades due to steady human population growth coupled with increased use of resources and habitat degradation, conflicts between humans and carnivores have greatly been expanded. In order to mitigate these conflicts based on a clear understanding of conflict patterns, applying the species distribution models as helpful methods has been suggested. Occurring the recent conflict betwee...
Dynamic modeling and simulation of fixed bed adsorption process was carried out by explaining the behavior of breakthrough curve parameter. Adsorption of sulfur compound, present in road fuel, has posed a great challenge. A model of fixed bed adsorption of benzothiophene from fuel was formulated with non-ideal plug flow behavior and considered velocity variation along a column. The model was so...
An important visual strategy in the visual control of driving during curve negotiation is tangent point orientation – directing gaze to the inside road edge in the area of interest (AOI) around the tangent point. Yet, while the phenomenon has been replicated in many studies at a qualitative level, and several computational models have been proposed to explain it, there is no consensus on whethe...
