Development of disaggregate models for estimating different property damage collision type frequencies in urban intersections has rarely been studied, particularly in Iran. It seems very little research work being implemented for studying the effect factors on collision type frequency at intersections. The main objective of this paper is to develop suitable statistical models to predict types o...

in recent research on modelling road collisions very little attention has been paid  to rear-end chain reaction collisions, which is characterized by more than two vehicles involved in a collision at the same time. the core aim of the present research is to develop a methodology to estimate such potential collision probabilities based on a proactive perspective, where deceleration rate to avoid...

Spondylolysis is a common cause of backache and the detection of subtle cases is therefore important. Oblique views considerably increase the detection rate (Appleby and Stabler 1969), but a number of cases require additional views. The 30#{176} oblique cranial tilt view is more reliable than the standard oblique views in detecting spondylolysis as it visualises the pars interarticularis tangen...

The anisotropic fluid equations governing a frictionless obliquely-flowing plasma around an essentially arbitrarily shaped three-dimensional ion-absorbing object in a strong magnetic field are solved analytically in the quasi-neutral drift-approximation, neglecting parallel temperature gradients. The effects of transverse displacements traversing the magnetic presheath are also quantified. It i...

Two fully loaded (80,000 pounds nominal weight) tractor semi-trailer trucks were impacted into an instrumented wall at 55 miles per hour and an oblique angle of 15 degrees to the wall. This effort was conducted under two separate contracts, one under FHWA and the other NHTSA. The objective of the FHWA contract was to determine lateral impact forces in heavy vehicle collisions with an instrument...

PURPOSE We wanted to examine the effect of graded recession and anteriorization of the inferior oblique muscle on patients suffering from unilateral superior oblique palsy. METHODS Inferior oblique muscle graded recession and anteriorization were performed on twenty-two patients (22 eyes) with unilateral superior oblique palsy. The recession and anteriorization were matched to the degree of i...

Numerical studies of the interplanetary “shock overtaking magnetic cloud (MC)” event are continued by a 2.5 dimensional magnetohydrodynamic (MHD) model in heliospheric meridional plane. Interplanetary direct collision (DC)/oblique collision (OC) between an MC and a shock results from their same/different initial propagation orientations. For radially erupted MC and shock in solar corona, the or...

Although cycling may be attractive for both economic and environmental reasons, cyclists are extremely vulnerable road users and subjected to falls or collisions with cars. Therefore, wearing a helmet is of crucial and vital importance considering the high percentage of head injuries in cyclists. The present research attempts to understand the degree of protection offered by a com...
