A Method for Assessing the Potential of Multifunctional Retrofitting of Rural Roofs Based on GF-2 Remote Sensing Imagery [PDF]

open access: yesSensors
Green roofs and photovoltaic (PV) roofs are important forms of roof retrofitting, and unused rural roofs provide favorable conditions for the development of green roofs and PV roofs.

Polyurethane adhesives in flat roofs [PDF]

open access: yesMATEC Web of Conferences, 2017
It is necessary to stabilize individual layers of flat roofs, mainly because of wind suction. Apart from anchoring and surcharge, these layers can be secured by bonding. At present gluing is an indispensable and widely used stabilization method.

Urban rooftops near sports pitches provide a safe haven for a declining shorebird [PDF]

open access: yesScientific Reports
Urbanisation has contributed to a severe decline in biodiversity worldwide. However, urban ecosystems can also play an important role in the conservation of threatened species, including ground-nesting birds such as the Eurasian Oystercatcher (Haematopus

DERIVATION OF BUILDING STRUCTURES FROM NOISY DIGITAL SURFACE MODELS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
In this work we present a novel approach for segementation of a noisy DSM to building structures and other non-building structures – normally trees – and the modeling of them. Mostly Digital Surface Models (DSMs) from only a few aerial images

Snow Load Shape Coefficients and Snow Prevention Method for Stepped Flat Roofs

open access: yesApplied Sciences, 2023
Excessive snow load and nonuniform snow deposition are the main factors leading to building collapses. The snow load shape coefficient represents the dimensionless snow load, and its value is related to the unbalanced distribution of snow.
