Lane detection is a developing technology that implemented in vehicles to enable autonomous navigation. Most lane systems are designed for roads with proper structure relying on the existence of markings. The main shortcoming these approaches they might give inaccurate results or not work at all situations involving unclear markings absence them. In this study one such approach detecting lanes ...

The problem of walking simulation for the quadruped search robot on a slope is described as an uncertainty system. In order to create the virtual ramp road environment, VRMLmodeling language is used to build a real environment, which is a 3D terrain scene in Matlab platform. According to the VRML model structure of the quadruped search robot, a guaranteed cost nonfragile robust controller is de...

This study compared the ability of binary logistic regression (BLR) and non-linear causal resource analysis (NCRA) to utilize a range of cognitive, sensory-motor, personality and demographic measures to predict driving ability in a sample of cognitively healthy older drivers. Participants were sixty drivers aged 70 and above (mean=76.7 years, 50% men) with no diagnosed neurological disorder. Te...

without any doubt, road safety (rs) needs a precise planning in road accident prevention. rs effects on different fields of the life. therefore, response to this need in order to promote the rs as well as to save more lives is the most asset in each country. in the recent years, statistics have been shown that the numbers of mortalities due to road crashes decreased. this shows the true motion ...

This paper studies the analysis of reductio ad absurdum by Ibn Sı̄nā (known to the Latin West as Avicenna), who was born in 980 in a village near the Bactrian town of Balkh on the Silk Road, and died in 1037 after a career spent moving around within the present boundaries of Iran. References to Ibn Sı̄nā’s writings are to his Arabic texts listed in the bibliography, and are given in the format pa...

We want to find a measure of how ‘curved’ a curve is. Since this ‘curvature’ should depend only on the ‘shape’ of the curve, it should not be changed when the curve is reparametrized. Further, the measure of curvature should agree with our intuition in simple special cases. Straight lines themselves have zero curvature. Large circles should have smaller curvature than small circles which bend m...

Abstract—Bezier curves have useful properties for path generation problem, for instance, it can generate the reference trajectory for vehicles to satisfy the path constraints. Both algorithms join cubic Bezier curve segment smoothly to generate the path. Some of the useful properties of Bezier are curvature. In mathematics, curvature is the amount by which a geometric object deviates from being...

spinal cord injuries (sci) are highly disabling and injuries. this study aims to describe the demographic and epidemiologic data on auto accident patients who were admitted at khatam alanbia hospital. the results obtained from 73 sci patients treated on the sci inpatient units of the khatam alanbia hospital (from march 2009 to march 2013) were evaluated retrospectively. then patient gender, age...
