abstract background: technical, human, operational and organizational factors have been influencing the sequence of occupational accidents. among them, organizational factors play a major role in causing occupational accidents. the aim of this research was to understand the iranian safety experts’ experiences and perception of organizational factors. methods: this qualitative study was conducte...

Real-time Precise Point Positioning (PPP) technique is being widely applied for providing precise positioning services with the significant improvement on satellite precise products accuracy. With the rapid development of the multi-constellation Global Navigation Satellite Systems (multi-GNSS), currently, about 80 navigation satellites are operational in orbit. Obviously, PPP performance is dra...

The aim of this exploratory study was to detect among decathletes types of specialization with the help of a one sample configural frequency analysis (CFA). The sample consisted of the performances of 514 decathlon athletes, who were ranked among the top 100 athletes of the world from 1984 to 2000. Due to the fact that some athletes were ranked repeatedly among the top 100 world’s best athletes...

There has been limited collaboration between researchers in human factors and operational research disciplines, particularly in relation to work in complex, distributed systems. This study aimed to investigate work at the interface between human factors and operational research in the case example of road resurfacing work. Descriptive material on the factors affecting performance in road mainte...

The paper deals with aim to design an OPAMP of Class AB to achieve high power efficiency and slew rate. To have high slew rate the focus of the proposed work as high slew rate contributes to the fast and dynamic output response. Power efficiency is driving factor from MOORE’S law. A Push pull OPAMP with current replicating branch is used to achieve symmetrical wave with high slew rate. Adaptive...

We present a memetic approach for multi-objective improvement of robustness influencing features (called robustness objectives) in airline schedules. Improvement of the objectives is obtained by making minor incremental changes to the flight schedule by retiming the flights and the aircraft rotations, subject to a fixed fleet assignment. Approximations of the Pareto optimal front are obtained b...
