We discuss the human role in hydropower system control, noting how it is different from other supervisory control environments and noting the typical shortcomings in current displays provided to hydropower system controllers. We describe steps towards evaluating proposed functional displays with industry hydropower controllers whose time with us was limited(More)
We present the design process of a highly portable integrated power system simulator developed to support investigation into human interface design for a complex hydro power system. The most important development phases of the simulator are described followed by insights that guided developers to the final version. The architecture of the simulator is(More)
This paper presents part of a project aimed at evaluating ecological interfaces in a real world complex system –a hydropower system. We investigate whether an advanced measurement method—here called the control adaptation method (CAM)—can be extended to evaluate how effectively a human operator is coupled to a complex process control environment. So far the(More)
This paper discusses the temporal fit of teams of controllers to a real world hydropower system (HPS) in a deregulated market environment, emphasizing how well displays support quality of control performance by industry controllers. The results of an empirical evaluation suggest that displays that integrate task constraints over appropriate time scales help(More)
Breast cancer is one of the leading causes of death in women worldwide. Therefore, ultrasound examination has become an important method of detecting breast tumors. However, given the special features of ultrasonic imaging, lesion segmentation is a challenging task in computer-aided diagnosis systems. In this study, we proposed a complex and automated(More)
The Na1.1V3O7.9 nanobelts have been synthesized by a facile and scalable hydrothermal reaction with subsequent calcinations. The morphologies and the crystallinity of the nanobelts are largely determined by the calcination temperatures. Ultrathin nanobelts with a thickness around 20 nm can be obtained, and the TEM reveals that the nanobelts are composed of(More)
