A microwave gradient meta-surface is designed and fabricated. The structure is consist of a stack of two-dimensional (x-axis and y-axis) arrays of gradually-varied sub-wavelength elliptical rings, a dielectric substrate and a metallic ground plane. Both theoretical and experimental studies are conducted to demonstrate that the carefully designed y-axis phase gradient meta-surface supports high-efficiency...
The shuffle operation is one of the bottlenecks invector DSPs. The partitioning problem of the shuffle matrix will have a great effect on the design of the shuffle unit, when dealing with the small grain data shuffle using a smaller-sized crossbar. The traditional matrix block partitioning solution will bring much chip area, power consumption and critical path delay. This paper presents a new matrix...
Effective power supplying service management is an important prerequisite for power supply enterprises to win in competitive market. In this paper, we analysis the characteristics of power supply enterprises, follow the thought of "Identifying problems - Finding problems - Solving problems", that is identifying problems based on the theory of Gaps model, establishing a service quality evaluating...
Effective customer satisfaction evaluation is an important prerequisite for power supply enterprises to win in competitive market. In this paper, we establish the power customer satisfaction evaluation index system based on previous studies. Then we prove the validity of this method through field investigations by using SAS. Finally, path coefficient analysis is conducted to get key factors to improve...
