Advancing deep learning-based detection of floating litter using a novel open dataset

Supervised Deep Learning (DL) methods have shown promise in monitoring the floating litter in rivers and urban canals but further advancements are hard to obtain due to the limited availability of relevant labeled data. To address this challenge, researchers often utilize techniques such as transfer learning (TL) and data augmentation (DA)....

From Deterioration to Revival: Approaches to the Conservation of Plastic Buildings

The four Futuro case studies (Futuro No. 000, Corfu-Futuro, Donaldson-Futuro, Munich-Futuro) presented in this journal document conservation approaches to plastic buildings and elements – in this case, glass-reinforced plastic (GRP) sandwich panels. They contribute to the definition of general conservation approaches, and at the same time...

RILEM TC 279 WMR round robin study on waste polyethylene modified bituminous binders: advantages and challenges

Inter-laboratory experiments were designed to evaluate the impact of plastic waste blended directly in bitumen and to assess the properties, using conventional and advanced bituminous binder testing. The blends targeted 5% of plastic waste in 95% bitumen, using two types of polyethylene (PE) primary (pellets) and secondary (shreds) waste. The...

The Global Petroleumscape and its Impacts on Design Practice

Over the last century the petroleum industry’s rapid growth has been accompanied by a steady flow of aggressively promoted petroleum-based products. The petroleumscape’s spatial expansion and visual representation achieved widespread citizen buy-in. Following World War II the use of plastic materials in the building industry significantly...

Kinetic Gravity Separation

Separations by density, such as the separation of non-ferrous scrap into light and heavy alloys, are often realized by means of heavy media. In principle, kinetic gravity separations in water can be faster and cheaper, because they do not rely on suspensions or salt solutions of which the density must be tightly controlled. Test results of a...
