To appropriately meet increasingly diverse customer needs, services are committed to certain configuration in a paradigm similar with product mass customization. This paper presents a hybrid approach based on ontologies and rules to achieve representing, acquiring and reasoning service configuration knowledge. Structural knowledge is represented by ontology and formalized by OWL, resulting in well-defined...
Attendance check is important in the work of students management. In this paper a students attendance check and personal identification system design based on fingerprint Sensor FPS200 and wireless communication module nRF903 is proposed. It is included fingerprint identification terminal equipment, floor relay station, building relay station and control center. We design a mix star network topologic...
Digital correlation techniques are used in photon correlation spectroscopy (PCS) experiments to gain information about the diffusion coefficient and thereby the size and distribution of submicron particle structures in fluid media. This paper presents a photon correlation system implemented by high performance FPGA (Field Programmable Gate Array). Owning to the digital nature of photon counting, correlators...
