Seismic Performance Of Masonry Cross Vaults

Considering the seismic behaviour of cultural heritage buildings, recent earthquakes have emphasised the high vulnerability of vaulted structures. In this regard, the present thesis deals with masonry cross vaults, among the most diffused and fascinating structural typologies of the European cultural heritage. After a thorough review of cross vault historical developments, the focus is shifted to the shaking table tests of a scaled arch. These two points provided valuable information to calibrate the finite element model of cross vault, discussed next. Finally, the influence of the main geometrical and mechanical parameters on the seismic capacity of cross vaults are examined by means of a sensitivity analysis.

This book gathers the peer-reviewed papers presented at the 13th International Conference on Structural Analysis of Historical Constructions (SAHC), held in Kyoto, Japan, on September 12-15, 2023. It highlights the latest advances and innovations in the field of conservation and restoration of historical and heritage structures. The conference topics encompass history of construction and building technology, theory and practice of conservation, inspection methods, non-destructive techniques and laboratory testing, numerical modeling and structural analysis, management of heritage structures and conservation strategies, structural health monitoring, repair and strengthening strategies and techniques, vernacular constructions, seismic analysis and retrofit, vulnerability and risk analysis, resilience of historic areas to climate change and hazard events, durability, and sustainability. As such the book represents an invaluable, up-to-the-minute tool, providing an essential overview of conservation of historical constructions, and offers an important platform to engineers, architects, archeologists, and geophysicists.

During earthquakes, masonry buildings are the most affected, and consequently, damage to these buildings leads to massive loss of life and property. Masonry buildings comprise probably the greatest share of overall housing stock, and in turn, understanding their performance during earthquakes is a pivotal problem in seismic regions. Masonry Construction in Active Seismic Regions presents details on the kinds of masonry building found in seismic regions of the world. The title describes interventions, such as retrofitted solutions, dynamic identification, and improved construction after earthquakes, that are equally applicable to regions of moderate and high seismicity. The book covers representative masonry buildings from active seismic regions, the material properties of masonry construction, numerical modelling techniques and computational advances, seismic performance of non-engineered masonry buildings, resilience in typical construction, retrofitting, and the cultural values and structural characterization of heritage masonry buildings in active seismic regions. This book is unique in its global and systematic coverage of masonry construction in seismic regions. Identifies the material properties of masonry construction from a seismic perspective Covers representative masonry buildings from active seismic regions, providing a benchmark to understand existing building stocks Provides numerical modelling techniques and reviews computational advances, including a large test database Details the seismic performance of non-engineered masonry buildings, as well as the cultural values and structural characterisation of heritage masonry constructions Analyses typical or vernacular constructions which have earthquake resilient features, such as Dhajji-Dewari, Borbone, Pombalino, and Himis

Living organisms are adapted to their environment. Modern compilers and runtime systems for computer software are no different: as part of a continuous optimization process, they can adapt the execution cycle of a program to the workload it operates on. This thesis brings novel ideas to the software optimization domain. It illustrates methodological and practical contributions that advance the state of the art for performance profiling techniques and adaptive runtime designs, backed by promising experimental results on industrial-strength benchmarks. Part of the results has been presented in flagship programming language venues.

The topic of proactivity of brain functions has become of growing interest in the cognitive neuroscience. Brain activity is no longer described solely in a reactive way, but also as preparatory and predictive of future events. This volume focuses especially on the neurocognitive activities associated with anticipatory processes of perceptual decision-making. What does the brain do to prevent mistakes? Is it possible to prevent speed and accuracy of a decision even before it is made? Why do some people perform better or worse than others? The volume answers these and other questions through the description of some original research. In particular, electroencephalographic investigations are illustrated which allowed to define a first version of the model known as “preparation-perception-action cycle”. Present findings reveal theoretical and practical implications which constitute a useful reference for researchers and scholars interested in discovering the aware and unaware ways in which our brain anticipates the future.

This PhD thesis consists of three projects: the first and the second ones, carried out at Sapienza University of Rome, deal with the design and synthesis of novel COX-2 selective inhibitors and dual COX-2 inhibitors/NO-releasing agents, respectively. The third project concerns the development of a novel BRD9 chemical probe and was realized at the University of Oxford (Department of Chemistry).

This volume collects the main results of the Author’s Ph.D. course in Electromagnetics and Mathematical Models for Engineering, attended at ‘Sapienza’ University of Rome from November 2011 to February 2015, in the Electromagnetic Fields 1 Lab of the Department of Information Engineering, Electronics and Telecommunications, under the tutoring of Prof. Alessandro Galli.
