Motion control of truck-mounted concrete pump booms is an important part construction work. The quality the boom movement will affect efficiency and safety operations. To make move quickly steadily, its hydraulic system needs to be improved. In this article, we firstly combine independent metering (IMC) active disturbance rejection (ADRC). that controls meliorated by replacing traditional propo...

Multiscale modeling for cement-based materials, such as concrete, is a relatively young subject, but there are already a number of different approaches to study different aspects of these classical materials. In this paper, the parameter-passing multiscale modeling scheme is established and applied to address the multiscale modeling problem for the integrated system of cement paste, mortar, and...

The lining system, used in tunnel boring machines, is made of precast concrete segments. use steel fibers this kind support system can not only decrease production time and costs but also improve compressive, tensile as well flexural behaviors. A study has been carried out to examine the mechanical properties segments Tabriz metro line-2 project using three types fibers: 3D, 4D, 5D. Various exp...

Tool support is an important factor for efficient development of parallel programs. Due to different goals, target systems, and levels of abstraction, many specialized tools and environments have been developed. A contrary approach in the area of parallel program analysis is offered by DeWiz, which focuses on unified analysis functionality based on the event graph model. The desired analysis ta...
