The Role of Soil Structure Interaction on the Seismic Resilience of Isolated Structures

open access: yesApplied Sciences, 2022
Resilience has become an interesting parameter to assess the seismic risk connected with functionality of structures. In this regard, losses due to earthquakes may be significantly reduced by applying isolation at the base of the structures.

Seismic vulnerability of churches in Faial and Pico islands, Azores [PDF]

open access: yes, 2012
Earthquakes represent one of the main cause of serious damage and loss of historic and architectural heritage. Interventions to preserve these building should start with a careful knowledge and assessment of their seismic vulnerability, in order to ...

Probabilistic Seismic Hazard Assessment of Sweden

open access: yesNatural Hazards and Earth System Sciences, 2023
Sweden is a low-seismicity, stable continental region where seismic hazard assessment is non-trivial. Diffuse seismicity, low seismicity rate, few large magnitude earthquakes and little strong motion data makes it difficult to estimate recurrence parameters and determine appropriate attenuation relationships.

Metasurface‐Enabled Active‐Like Passive Radar

open access: yesAdvanced Science, EarlyView.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Tuned Mass Damper Design for Slender Masonry Structures: A Framework for Linear and Nonlinear Analysis

open access: yesApplied Sciences, 2021
The paper presents a proposed framework to optimize the tuned mass damper (TMD) design, useful for seismic improvement of slender masonry structures. A historical masonry chimney located in northern Italy was considered to illustrate the proposed TMD ...

Application of wavelet analysis in tool wear evaluation using image processing method [PDF]

open access: yes, 2018
Tool wear plays a significant role for proper planning and control of machining parameters to maintain the product quality. However, existing tool wear monitoring methods using sensor signals still have limitations.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,
