Background and Aim: Internet addiction means excessive and unnecessary use of the Internet. The aim of this study was to investigate the role of brain-behavioral systems in Internet addiction among university students. Materials and Methods: This was a descriptive and correlational research. The statistical population was all the students of Islamic Azad University, Karaj Branch in the academi...

the air transport industry is seeking to manage risks in air travels. its main objective is to detect abnormal behaviors in various flight conditions. the current methods have some limitations and are based on studying the risks and measuring the effective parameters. these parameters do not remove the dependency of a flight process on the time and human decisions. in this paper, we used an hmm...

Landing is a challenging flight phase for automatic control of fixed-wing aircraft. For unmanned air vehicles in particular, it is imperative that model uncertainty be considered in the control synthesis. These vehicles tend to have limited sensors and instrumentation, yet must achieve good performance in the presence of modelling errors and exogenous inputs such as turbulence. Quantitative Fee...

BACKGROUND Knowing the high and low peaks in comfort during a flight could be useful in prioritizing aircraft interior improvements. OBJECTIVE The first objective of this study was to identify whether there are differences in comfort experiences during different phases of a flight. The second objective of this study was to identify similarities between recalled and real time reported comfort ...

conclusions: thus, identifying the hf patients before the flight and providing them proper education about the events that may occur during flight is necessary. results: hf patients are more prone to experience respiratory distress, anxiety, stress, cardiac decompensation, and venous thromboembolism (vte) during air travel. although stable hf patients can tolerate air travel, but those with acu...

The NASA F-15 Intelligent Flight Control System project team has developed a series of flight control concepts designed to demonstrate the benefits of a neural network-based adaptive controller. The objective of the team is to develop and flight-test control systems that use neural network technology to optimize the performance of the aircraft under nominal conditions as well as stabilize the a...

1. In restrained locusts we have reexamined the effects on the flight rhythm of stimulating wing stretch receptors. Contrary to earlier reports, we have found a strong phasedependent influence. Single stimulus trains delivered close to the onset of depressor motor activity reset the flight rhythm. When presented approximately midway between depressor bursts, they had no effect. 2. Stretch-recep...
