A new construction method of two-dimensional (2D) variable-weight optical orthogonal codes (VWOOCs) is proposed for high-speed optical code-division multiple-access (OCDMA) networks supporting multiple qualities of services (QoS). The proposed codes
The paper introduces a method of autonomous virtual hand behavior construction in virtual manufacturing environment. The purpose of this research is to realize an intelligent and efficient virtual hand. The advantage of this new mechanism is that the
