uav based photogrammetry and integrated technologies for Architectural applications methodological strategies for the after quake survey of vertical Structures in mantua italy
Sensors, 2015Co-Authors: Cristiana Achille, Silvia Chiarini, Stefano Cremonesi, Francesco Fassi, Luigi Fregonese, Andrea Adami, Laura TaffurelliAbstract:This paper examines the survey of tall buildings in an emergency context like in the case of post-seismic events. The after-earthquake survey has to guarantee time-savings, high precision and security during the operational stages. The main goal is to optimize the application of methodologies based on acquisition and automatic elaborations of photogrammetric data even with the use of Unmanned Aerial Vehicle (UAV) systems in order to provide fast and low cost operations. The suggested methods integrate new technologies with commonly used technologies like TLS and topographic acquisition. The value of the photogrammetric application is demonstrated by a test case, based on the comparison of acquisition, calibration and 3D modeling results in case of use of a laser scanner, metric camera and amateur reflex camera. The test would help us to demonstrate the efficiency of image based methods in the acquisition of complex architecture. The case study is Santa Barbara Bell tower in Mantua. The applied survey solution allows a complete 3D database of the complex Architectural Structure to be obtained for the extraction of all the information needed for significant intervention. This demonstrates the applicability of the photogrammetry using UAV for the survey of vertical Structures, complex buildings and difficult accessible Architectural parts, providing high precision results.

Musica e architettura. Le opere di Igor Stravinsky per la basilica di San Marco a Venezia
place:Milano, 2019Co-Authors: Oliveri DAbstract:Il 13 settembre 1956, Stravinsky diresse nella basilica di San Marco a Venezia la prima esecuzione del "Canticum Sacrum" (1955), insieme con le "Variazioni-corali sulla canto natalizio Vom Himmel hoch\u2026" (1955-56). Il "Canticum" era stato realizzato su commissione del Festival delle Biennale e costituisce un esempio dell'approccio del compositore alla tecnica dodecafonica. Le "Variazioni-corali" presentano quasi il medesimo organico del "Canticum" e sono invece da considerarsi come una sorta di ripensamento creativo delle "Variazioni canoniche" BWV 796-796a di Johann Sebastian Bach.September 13th 1956, Stravinsky conducted at the basilica of St. Mark in Venice the first performance of the "Canticum Sacrum" (1955), together with the "Choral-Variations on the Christmas Carol Vom Himmel hoch...\u201d (1955-56). This work is not only the transcription for mixed chorus and orchestra of the "Canonische Var\ue4nderungen" BWV 796-796a, but also an original and creative reinvention of Bach\u2019s organ masterpiece of 1746-47, that has a deep relation with the Architectural Structure of the church. In \u2018Variations II-V\u2019 the composer introduced the chorus, but singing only the first four verses of Martin Luther\u2019s text, and under some aspects the score reveals - like the musice of the "Canticum Sacrum" - the attraction of Stravinsky towards the music of Anton Webern

a new idea of bim system for visualization web sharing and using huge complex 3d models for facility management
ISPRS - International Archives of the Photogrammetry Remote Sensing and Spatial Information Sciences, 2015Co-Authors: Francesco Fassi, Cristiana Achille, Alessandro Mandelli, Fabrizio Rechichi, Stefano ParriAbstract:Abstract. The work is the final part of a multi-year research project on the Milan Cathedral, which focused on the complete survey and threedimensional modeling of the Great Spire (Fassi et al., 2011) and the two altars in the transept. The main purpose of the job was to prepare support data for the maintenance operations involving the cathedral since 2009 and still in progress. The research job had begun addressing our efforts to identify which methods would allow an expeditious but comprehensive measure of complex Architectural Structure as a whole. (Achille et al., 2012) The following research works were focused mainly to find an efficient method to visualize, use and share the realized 3D model.

static extraction and conformance analysis of hierarchical runtime Architectural Structure using annotations
Conference on Object-Oriented Programming Systems Languages and Applications, 2009Co-Authors: Marwan Abiantoun, Jonathan AldrichAbstract:An object diagram makes explicit the object Structures that are only implicit in a class diagram. An object diagram may be missing and must extracted from the code. Alternatively, an existing diagram may be inconsistent with the code, and must be analyzed for conformance with the implementation. One can generalize the global object diagram of a system into a runtime architecture which abstracts objects into components, represents how those components interact, and can decompose a component into a nested sub-architecture. A static object diagram represents all objects and inter-object relations possibly created, and is recovered by static analysis of a program. Existing analyses extract static object diagrams that are non-hierarchical, do not scale, and do not provide meaningful Architectural abstraction. Indeed, Architectural hierarchy is not readily observable in arbitrary code. Previous approaches used breaking language extensions to specify hierarchy and instances in code, or used dynamic analyses to extract dynamic object diagrams that show objects and relations for a few program runs. Typecheckable ownership domain annotations use existing language support for annotations and specify in code object encapsulation, logical containment and Architectural tiers. These annotations enable a points-to static analysis to extract a sound global object graph that provides Architectural abstraction by ownership hierarchy and by types, where Architecturally significant objects appear near the top of the hierarchy and data Structures are further down. Another analysis can abstract an object graph into a built runtime architecture. Then, a third analysis can compare the built architecture to a target, analyze and measure their structural conformance, establish traceability between the two and identify interesting differences.

tool support for statically checking the structural conformance of an object oriented system to its runtime architecture
Conference on Object-Oriented Programming Systems Languages and Applications, 2008Co-Authors: Marwan Abiantoun, Jonathan AldrichAbstract:Maintaining the conformance of an implementation to its architecture is difficult in practice since developers often make changes that degrade the Architectural Structure. We present tools for statically checking the structural conformance of a system to its runtime architecture.

archjava connecting software architecture to implementation
International Conference on Software Engineering, 2002Co-Authors: Jonathan Aldrich, Craig Chambers, David NotkinAbstract:Software architecture describes the Structure of a system, enabling more effective design, program understanding, and formal analysis. However, existing approaches decouple implementation code from architecture, allowing inconsistencies, causing confusion, violating Architectural properties, and inhibiting software evolution. ArchJava is an extension to Java that seamlessly unifies software architecture with implementation, ensuring that the implementation conforms to Architectural constraints. A case study applying ArchJava to a circuit-design application suggests that ArchJava can express Architectural Structure effectively within an implementation, and that it can aid in program understanding and software evolution.

Reconciling the needs of Architectural description with object-modeling notations
Science of Computer Programming, 2002Co-Authors: David Garlan, Shang-wen Cheng, Andrew J. KompanekAbstract:Complex software systems require expressive notations for representing their software architectures. Two competing paths have emerged. One is to use a specialized notation for architecture, an architecture description language (ADL). The other is to adapt a general-purpose modeling notation, such as UML. The latter has a number of benefits, including familiarity to developers, close mapping to implementations, and commercial tool support. However, it remains an open question as to how best to use object-oriented notations for Architectural description, and, indeed, whether they are sufficiently expressive, as currently defined. In this paper, we take a systematic look at these questions, examining the space of possible mappings from ADLs into UML. Specifically, we describe (a) the principal strategies for representing Architectural Structure in UML; (b) the benefits and limitations of each strategy; and (c) aspects of Architectural description that are intrinsically difficult to model in UML using the strategies.
