Outdoor sports equipment without maintenance usually caused injury to users. This paper proposes to design an App notification system combine with IoT to monitor the equipment status. We converted our action signal into frequency domain for analysis. But the useless signal might decline classifier efficiency. Therefore we propose an empirical support vector machine (SVM) to reduce the useless signal...
Based on the merits of handy and flexibility for two-wheeled self-balancing vehicles (TWSBV), some of the practicable applications have been enhanced and extended. In this research, we implement an empirical design method by utilizing distinct fuzzy controllers for a TWSBV, which can be implemented by Arduino Leonardo development platform, with performing the standing balance, moving balance and carrying...
In this study, we proposed a controller design method of a two wheeled self-balancing vehicle (TWSBV) based on a fuzzy T-S model (T-S Fuzzy) associated with a genetic algorithm (GA). To achieve the stable controller of TWSBV, we used GA to determine the proper state feedback gains and used the T-S Fuzzy formed by the heuristic experiment with two fuzzy membership functions: vehicle body angle and...
With the recent popularization of smartphones, more attention has been given to design dynamic keys for smartphone communications. In this paper, we particularly work to meet the requirement of encrypted information sharing among closely located smartphones. Considering the fact that GPS locations of smartphones are available, we propose a key agreement scheme, denoted by LSKA, based on the location...
