Often, all too often, global working-class solidarity remains fragile, conditional or fails to be realized in practice, whatever the lofty rhetoric may be.The present paper explores one possible explanation: workers in the North profit from the exploitation of workers in the South through cheap commodities and services, and additional job opportuni
3D city models are being extensively used in applications such as evacuation scenarios and energy consumption estimation.The main standard for 3D city models is the CityGML data model which can be encoded through the CityJSON data format.CityGML and CityJSON use polygonal modelling in order to represent geometries.True topological data structures h
The technique of sound insulation has a wide range of potential applications in Dining environment noise control and architectural acoustics.The rapid development of acoustic artificial materials has provided alternative solutions to design sound insulation structures.However, the realization of single-layer planar structures with bidirectional aco
