In this paper, based on double auction and cell membrane optimization, a novel cloud resource management scheme is proposed with the economic methods adopted and the characteristics of resources and market in cloud environment considered. In the proposed scheme, the resources are priced by double auction, and the best solution for cloud resource allocation is got by cell membrane optimization algorithm...
The main purpose of workload measurement is to identify conditions for overload so that they can be avoided by design. The operators' workload peak is difficult to measure by subjective evaluation. Pupil diameter is widely used as a factor to measure workload sensitively, so it's necessary to study the relationship between the workload peak and pupil diameter measurement. Eight trials were designed...
The purpose of this paper is to analyze the differences of distributed flight reference (DFR) and non-distributed flight reference (NDFR) from an ergonomics perspective, for the design of more practical and efficient helmet-mounted display(HMD). Eye tracking technology was adopted in this study to compare these two different information formats. Static pictures of two flight references were used as...
Reach envelope is one of the design tools to ensure industrial workspace accommodates users. A reach envelope transformation model based on the anthropometric measurement data was built in a previous study, in this paper, an experiment was designed to verify the model. 6 male subjects' reach data were collected using motion capture system with a sample rate of 120Hz. True reach distance was estimated...
The purpose of this paper is to provide reference for the design of more practical and efficient non-distributed flight reference(NDFR) symbology of helmet-mounted display(HMD) by comparing four kinds of attitude symbologys (include climb-dive angle and roll). The flight references were NDFR, NDFR-R (NDFR plus zero-degree Climb-Dive Angle CDA reference), NDFR-M (mini-arc NDFR) and ANDFR(Advanced NDFR)...
