Abstract Background and aims: One of the major concerns in the oil and gas drilling industry are Blowouts. Blowout could have severe consequences, such as fire and explosions, releases of toxic gases and environmental disasters. The aim of this study is to identify the root causes of kick and blowout in drilling industry. Methods: In this study, FTA investigates root causes of a k...
Introduction: Exploration and development of onshore oil and gas fields involve a number of risks related to loss of human lives, pollution, and loss of material assets. One of the major concerns in the oil and gas drilling industry are Blowouts. Blowout could have severe consequences, such as fire and explosion, releases of toxic gases and environmental disasters. The aim of this study is to...
The late detection of the kick (the entrance of underground fluids into oil wells) leads to oil well blowouts. It causes human life loss and imposes a great deal of expenses on the petroleum industry. This paper presents the application of adaptive neuro-fuzzy inference system designed for an earlier kick detection using measurable drilling parameters. In order to generate the initial fuzzy inf...
The purpose of this study was to examine the difference between two types of the soccer instep kick in temporal sequence of motion and muscle electromyography, during forward swing phase of the kick. Ten elite soccer players, volunteered as subjects in the study. To culculate the kinematics data, we used DLT method with two video camera that filmed five markers fixed on anatomical points o...

Approaching and kicking the ball toward the goal is the very essence of robotic soccer. However, for humanoid robots, it is hard to make a fast and stable kick as it includes large momentum changes while standing on a single foot. Simple keyframe based approaches tend to fail due to differences between robots or external perturbations, so they need to be executed slowly. Slow execution increase...
The purpose of this study was to investigate joint kinematics of the kicking leg in Taekwondo and to examine the role of inter-joint coordination of the leg in producing the kicking velocity. A new inter-joint coordination index that encompasses three- dimensional hip and knee motions, was defined and applied to the joint kinematic results. Twelve elite Taekwondo athletes participated in this s...
The aim of this study was an analysis of the time required to swim to a victim and tow them back to shore, while perfoming the flutter-kick and the dolphin-kick using fins. It has been hypothesized that using fins while using the dolphin-kick when swimming leads to reduced rescue time. Sixteen lifeguards took part in the study. The main tasks performed by them, were to approach and tow (double ...
Objective: Since direct foot kick is one of the most important strikes in Jeet Kune Do, its effectiveness depends on both the force of the hit and balance control during and after the hit execution, this study undertaken to examine the effect and persistence of eight-week of core stability training on balance and force of a direct foot kick of elite young male Jeet Kune Do (Wushu) athletes. Me...
Incorporating a dynamic kick engine that is both fast and effective is pivotal to be competitive in one of the world’s biggest AI and robotics initiative: RoboCup. Using the NAO robot as a testbed, we developed a dynamic kick engine that can generate a kick trajectory with an arbitrary direction without prior input or knowledge of the parameters of the kick. The trajectories are generated using...
