This paper searches for a connection between volcanoes and solar variability. Solar events have been investigated as possible interference with hazardous natural on Earth. The first results pointed out that during the minimum, frequency strength of increased. However, variability is not only factor disturbing volcanic eruptions; there also seasonality. There double from Sun volcanoes, one cycle...

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...

As robots tend to work cooperatively with humans in shared workplaces, safety as regards robothuman interactions has caused a great deal of concern in the robot community, and control strategies have become a hot topic in robotics research. In order to guarantee the robot’s safety and continuous motions, this paper proposes a novel safety-control strategy, which is strictly conservative and whi...

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...

We explore the connections between crustal shortening, volcanism, and mantle dynamics in Atlas of Morocco. In response to compressional forces strain localization, this intraplate orogen has evolved far from convergent plate margins. Convective effects, such as lithospheric weakening plume-related contributed important ways building high topography. seek better understand how processes interact...

The official material used in table tennis balls was changed from celluloid to plastic, a material free of celluloid, in 2014. The purpose of this study was to understand the differences and similarities in the two types of ball materials by comparing their behavior upon collision with a table. The behavior of the balls before and after collision with a table, at various initial speeds ranging ...
