This paper illustrates the results of an experimental campaign performed on a scale prototype base dissipator called Mini Tribological ROCKing Seismic Isolation Device. device allows smooth, controlled and damped rocking by means frictional layers viscous elastic springs, which aim at decoupling frequencies superstructure, dissipating energy during motion re-centering system once external actio...

Large-scale tanks are widely used for storing chemicals and fuels. Their failure due to natural (e.g., earthquakes) and/or man-made hazards can lead disastrous consequences. Nonetheless, they often constructed in seismic-prone regions. For this reason, base isolation is the seismic protection of large tanks, aiming “decouple” superstructure from imposed ground motions. In study, a combined opti...

The design of heat exchanger networks (HEN) is a well-studied problem in process synthesis and an ideal test base to benchmark methods and techniques in the field. Despite a significant number of relevant publications, networks are still designed under assumptions of fixed operating conditions. Significant variations in supply and demand, alongside a need for efficient management in energy mark...

One of the most important contributions Japanese researchers is proposition superstructure concept. Umeda and coworkers proposed in 1972 a system structure for reaction-separation process which split ratios determine connecting flows. Later, this concept changed to parameter and, finally, superstructure. Since 1980, superstructure-based optimization has been very active field Process Systems En...

performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (vce) could be considered as one of the main causes of bridges collapse. in most of bridge design codes, for seismic analysis of bridges, vce is not taken into account or a distinguished method isn’t presented for assessment of vce. in the present work, the effect of vce on two existing...

This article studies the struggle between classes in George Orwell’s novel Animal Farm (1945). The most suitable school of literary criticism to tackle such a subject is that Marxism. Two basic Marxist principles are at center study: class conflict and notion base superstructure. addresses ongoing occurring humans pigs on one hand lower-class animals other. Three main questions have been addres...

Since its inception, Marxism has showcased the scientific superiority of political economy over economics. This article argues that Mao Zedong played an important role in demonstrating this superiority. In his A Critique Soviet Economics , criticised for economic focus, which underestimated importance politics and ideology. It was essential, argued, to explore how ideological superstructure aff...
