A single-base-station ultra-wideband (UWB) positioning system with a circular antenna array is given in this study. MUSIC algorithm and pulse amplitude measurement are employed to achieve accurate distance and angle measurement for precise positioning. Compared with the traditional correlation function algorithm in dense multipath environments, MUSIC algorithm has high multipath resolution capability...
The Cave Automatic Virtual Environment (CAVE) system is a fully immersive virtual reality system, which can provide users with a realistic experience and a large freedom of interactions. In this paper, we propose vDesign, a CAVE-based virtual design environment using finger interactions. Specifically, we focus on the function of image segmentation and composition in the vDesign system. In vDesign,...
The numerical simulation of conventional air-cooled unit and a new air-cooled one in which the incoming air is swirled by adding a swirler under the different angles of vane in the swirler has been made by employing actual data of Longshan power plant based on FLUENT software. Flow fields of the two kinds of units are obtained and compared. The most appropriate angle of vane in the swirler for heat...
Both static and kinematic testings are investigated by using IGS 5min, 30s and 5s-interval precise satellite clock products in precise point positioning (PPP) solution. Test results show that the sampling rate of IGS satellite clock has very little effect on the static PPP solution. All the three types of sampling intervals of precise satellite clock can satisfy mm-cm level of positioning accuracy;...
A novel brain computer interface (BCI) is implemented in this study, which only depends on auditory modality. The subjects voluntary recognition of the property (e.g. voice laterality) of a target human voice makes the discriminability between brain responses to target and non-target voices in a random sequence. EEG data from eight subjects showed that the amplitude of N2 and late positive component...
