A method of attitude estimation with a low-cost, strap-on MEMS sensor was proposed in the article.The method relies on dynamic gyroscope bias change estimation and updates during detected stops of the robot.The algorithm has been tested in laboratory with iRobot Roomba robot and should be improved to be useful in an industrial environment.The measu
This study examined the effects ego depletion (ED) and state anxiety (SA)have on performance changes in dart-throwing, a perceptual-motor task, using a Latent Curve Model chainsaw file (LCM).Twenty-two men, who had never played darts before, were recruited and randomly assigned to two counterbalanced groups: Group A was exposed first to ED and then
Abstract Cortisol is often measured as a marker for stress.Therefore, a profound validation of the time-lag between the stressor and the increase and peak in cortisol levels is needed.No study measured both the urinary and salivary cortisol poise pads in bulk time-lag after a psychological stressor.In this study, we used a frequent sampling study d
Alternaria gansuensis, a seed-borne fungus of standing milkvetch (Astragalus adsurgens), is the most common pathogen of this plant species and causes yellow stunt and root rot.Although plant resistance to this disease has been identified, a better understanding of read more the nature of this resistance will help improve and optimize its implementa
Fusion has often been billed as the ultimate 21st century sustainable energy source.However, not only is the pace of the program glacially slow, it seems to recede further and further into the future.For instance, when the ITER Tokamak was approved in 2005, the date for the first plasma was 2016.As this is written in 2018, the date has moved back t
