Abstract: Selecting a mechanism for a machine tool that will best suit the needs of a forecast set of rigidities can be a difficult and costly exercise. This problem can now be addressed using a ...

Abstract: This paper introduces several new types of parallel mechanisms with prismatic actuators whose degree of freedom is dependent on a constraining passive leg connecting the base and the platform. ...

Abstract: Selecting a configuration for a machine tool that will best suit the needs of a forecast set of requirements can be a difficulty and costly exercise. This problem can now be addressed using ...

Abstract: The prefabricated segmental column using posttensioning technology has become an ideal candidate for rapid and environmentally friendly construction. To avoid damage to the segment joint during a seismic event and enhance ...

Abstract: To improve the performance of epoxy grouting materials and achieve better repair of microcracks in cast-in-place concrete bridge deck pavements, polydimethylsiloxane (PDMS) and diluent were used to modify epoxy resin. The ...

Abstract: Quantifying the impacts of climate change and human activities on runoff variation has drawn considerable concern. In this study, a modified method of slope change ratio of accumulative quantity (modified SCRAQ) has been ...
