ZJ200 Portable Steel Bridge has its roots in the Bailey design, but the application of high-grade steels and advanced computer design and finite element analysis (FEA) techniques led to more effective structures. The design of the Bridge is modular, allowing full spans up to 60 meters in 3.048 m increments. Highways Loads up to HS25-44 have been proven during extensive testing.

Abstract The simple digital filters are not sufficient for digital modeling of systems with distributed parameters. It is necessary to apply more complex digital filters. In this work, a set of filters, called the digital function filters, is proposed. It consists of digital filters, which are obtained from causal and stable filters through some function transformation. In this paper, for several basic functions: exponential, logarithm, square root and the real power of input filter, the recursive algorithms of the digital function filters have been determined The digital function filters of exponential type can be obtained from direct recursive formulas. Whereas, the other function filters, such as the logarithm, the square root and the real power, require using the implicit recursive formulas. Some applications of the digital function filters for the analysis and synthesis of systems with lumped and distributed parameters (a long line, phase shifters, infinite ladder circuits) are given as well.
