Abstract Water resources allocation is an important technical tool to alleviate the conflict between water supply and demand, improve utilization efficiency, achieve control target of total utilization. However, current theory immature, there are few objective quantitative methods, which leads relatively backward practice. Moreover, amounts allocable change dynamically, makes static single trad...

Industry trends aimed at integrating higher levels of circuit functionality have triggered a proliferation of mixed analog-digital systems. Magniied noise coupling through the common chip substrate has made the design and veriication of such systems an increasingly diicult task. In this paper we present a fast eigendecomposition technique that accelerates operator application in BEM methods and...

RF integrated circuit designers make extensive use of simulation tools which perform nonlinear periodic steady-state analysis and its extensions. However, the computational costs of these simulation tools have restricted users from examining the detailed behavior of complete RF subsystems. Recent algorithmic developments , based on matrix-implicit iterative methods, is rapidly changing this sit...

This chapter presents an accurate and efficient method for determination of parasitic capacitances in submicron integrated circuits. The method uses a 3-D finite element model in which the conductor charges are approximated by a piece-wise linear function on a web of edges located on the surface of the conductors. This yields a system of Green’s function integral equations that is solved by a n...

The paper presents a methodology for simulating the static and dynamic performance of integrated circuits in the presence of electro-thermal interactions on the integrated circuit die. The technique is based on the coupling of a FEM program with a circuit simulator. In difference to other known simulator couplings the time step algorithm is used. Its implementation into simulation tools is desc...
