In a shared buffer packet switch, a good buffer management scheme is needed to reduce the overall packet loss probability and improve the fairness between different users. In this paper, a novel buffer control scheme called partial sharing and partial partitioning (PSPP) is proposed. The PSPP is an adaptive scheme that can be dynamically adjusted to the(More)
Flexible and lightweight graphene nanosheet (GN)/waterborne polyurethane (WPU) composites which exhibit high electrical conductivity and electromagnetic shielding performance were prepared. Covalently modifying GNs with aminoethyl methacrylate (AEMA; AEMA-GNs) through free radical polymerization effectively inhibited the restacking and aggregation of the(More)
It is known that microscopic spherulite growth plays an important role in macroscopical properties such as elastic moduli of some semicrystalline polymers. Ultrasonic spectroscopy can be used to quantitatively determine the role of spherulites. As a first approximation, spherulitic polymers are modeled as a material with spherical inclusions in an amorphous(More)
In this study, we developed a simple and powerful method to fabricate flexible and lightweight graphene-based composites that provide high electromagnetic interference (EMI) shielding performance. Electrospun waterborne polyurethane (WPU) that featured sulfonate functional groups was used as the polymer matrix, which was light and flexible. First, graphene(More)
In this article the direct domain-mapping technique is applied in the boundary element method (BEM) to investigate the heat conduction in composites consisting of multiple anisotropic media with embedded point heat sources. By use of a linear coordinate transformation, the physical domain is mapped to an auxiliary plane for 2D or space for 3D, where the(More)
In a shared buffer packet switch, a good buffer management scheme will reduce the overall packet loss probability and improve the fairness among different output queues. In this paper, a novel buffer control scheme called threshold-based partial sharing (TPS) is proposed. The key idea of the TPS is to separate the output ports into active and inactive(More)
