Frequency and time domain models are developed for backplane (BP), printed circuit board (PCB), and silicon interposer (SI) links using six-port transfer matrices (ABCD matrices) for bumps, vias and connectors, and coupled multiconductor transmission lines for traces. The six-port transfer matrix approach enables easy computation of the transfer function, as well as near-end and far-end crosstalk...
Natural gas-fired cogeneration power plant is the key joint which connects the natural gas pipeline network, power grid and district heat supply network. Thus its supply and consumption capacity of heat-power-gas is pivotal to the coordination of urban energy system. Based on material and energy balance principle, the process model of a natural gas-fired combined cycle cogeneration power plant is...
In radar observation, different ray paths, which influence the three-dimensional gridding process, is due to the different gradients of reflectivity. The earth's radius model, which could not describe the radar ray path in a certain atmospheric thermodynamic condition, is the average condition of the radar ray pathway. In order to get the mosaic data of a certain thermodynamic condition, we need an...
The sector partition is an important part of airspace planning. The research on the sector division methods is of great significance in controlling to clear the air traffic flow in the region, relaxing the pressure of air traffic controlling effectively, and increasing air traffic flow to ensure flight safety. This paper provides the new method of sector division based on the Power diagram. With Power...
Application of weathering and cold-formed steel in transmission lines can reduce steel consumption and environmental pollution. Some advances in studies on the weathering and cold-formed steel in transmission tower are introduced. Firstly, corrosion-resistant tests of weathering steel samples under different simulating technical atmospheres were carried out separately for 240 hours. It shows that...
