A stepper motor control system is introduced in the paper which adopted high-performance AVR microcontroller Atmega128 and serial communication. The system mainly consists of host computer (PC), console (Single Chip Machine) and a stepper motor. The data is interacted by the serial port between PC and console. Ultimately, the direct control of stepper motor by the PC is achieved. After debugging of...
Generalized data center can be established to manage and maintain heterogeneous application systems as a whole in university, which promotes capability of application services and reduces workload of other departments. Generalized data center's architecture based on network storage and backup technology is proposed, in which application systems are divided into fixed data and change data. Fixed data...
Visual attention plays a vital role for humans to understand a scene by intuitively emphasizing some focused objects, and recent work in the computational model of visual attention has demonstrated that a purely bottom-up approach to identify salient regions within an image can be successfully applied to diverse and practical problems. Being aware of this, we propose a new approach of extracting objects...
