Reconstruction of the face with skin-grafted muscle flaps: Optimizing the aesthetic outcome

2011

BACKGROUND: Reconstruction of large defects in the temporal region can be performed with skin grafts or pedicled or free flaps. Results are often not optimal because of the patch of a skin graft, lack of availability of local flaps, and distant skin from free flaps. A technique for reconstruction of these defects with local tissue is presented in this article that uses superficial musculoaponeurotic system (SMAS) plication to allow wide advancement of a cervicofacial flap. METHODS: Once the defect is outlined, a face-lift-like skin incision is used to raise the flap. The SMAS is plicated with two purse-string sutures that relieve tension on the flap and allow maximal advancement. Thirteen f…

3D digitization of transparent objects by polalization techniques in IR & by triangulation in UV

2011

Two non-conventional methods for the 3D digitization of transparent objects via non-contact measurement are reported in this thesis. 3D digitization is a well acknowledged technique for opaque objects and various commercial solutions based on different measurement approaches are available in the market offering different types of resolution at different prices. Since these techniques require a diffused or lambertian surface, their application to transparent surfaces fails. Indeed, rays reflected by the transparent surface are perturbed by diverse inter-reflections induced by the refractive properties of the object. Therefore, in industrial applications like quality control, the transparent …

Structures de déformation induites par surpressions de fluide dans les environnements sous-glaciaires et marin profonds : implications paléoenvironne…

2014

Soft-sediment deformation structures (SSDs) occur in unconsolidated sediments, during or shortly after deposition. SSDs are abundant in subglacial and deep-marine environments because of the development of fluid overpressure. Case studies of these two sedimentary environments were used (1) to reconstruct palaeoenvironments from SSDS, and (2) to define the impacts of SSDS on glacial morphologies and (3) petrophysical properties.(1) Analyses of strain regimes, deformation mechanisms, and chronologies in SSDs served to improve palaeoenvironmental reconstructions. These structures were used as proxys to estimate variations of ice flow velocities, ice thickness, meltwater production, and positio…

Chest fistula repair

2020

Chest wall plays a fundamental role in the human body, as it represents a protective cage around vital organs such as heart and lungs. Chest wall fistula is a rare and insidious condition that could lead to severe functional and aesthetical consequences, and thus represents a serious surgical challenge. Goals of reconstructive surgery are to preserve the respiratory function, to provide visceral protection, and to assure the best possible cosmetic outcome. In this chapter, we present an overview of all key principles in chest wall fistula management and repair.

Resilient cities and sustainable urban mobility in Sicily

2018

The global crisis that in recent years has been investing our planet at different levels - social, economic, political, cultural, environmental - has determined a constant change in the quality of life in the cities. Cities, unfortunately, increasingly vulnerable characterized by insecurity, uncertainty, unpredictability due to mistakes made in the past. This is why, today, urban planning is called to satisfy the new needs of the community through a planning that must be adapted to change. In this scenario, urban centers - in order to ensure high levels of quality of life and responsible management of territorial resources - they must re-examine their governance, their strategies for expans…

3D Reconstruction of Dynamic Vehicles using Sparse 3D-Laser-Scanner and 2D Image Fusion

2016

International audience; Map building becomes one of the most interesting research topic in computer vision field nowadays. To acquire accurate large 3D scene reconstructions, 3D laser scanners are recently developed and widely used. They produce accurate but sparse 3D point clouds of the environments. However, 3D reconstruction of rigidly moving objects along side with the large-scale 3D scene reconstruction is still lack of interest in many researches. To achieve a detailed object-level 3D reconstruction, a single scan of point cloud is insufficient due to their sparsity. For example, traditional Iterative Closest Point (ICP) registration technique or its variances are not accurate and rob…

Maison Particulière. Graphic Reading and Virtual Reconstruction

2021

De Stijl, a modern and avant-garde movement of the early twentieth century, is considered the link between the pre-1914 avant-garde and the post-1918 International Style. The name derives from the magazine founded in 1917 and used for the promotion of the ideals ofNeoplasticism, theorised by Theo VanDoesburg. In 1924 Van Doesburg published the essay Tot een beeldende architectuur in which he explained a 16 points manifesto on the neoplastic vision of modern architecture. The analysis of the drawings and contra-constructions and the comparative reading of all the original drawings allowed for a series of graphic interpretations, which made the project understandable. This interpretative-reco…

I Telamoni del Tempio di Zeus ad Agrigento: rilievi, disegni e ricostruzioni

2013

Oggetto dello studio qui presentato è la ricostruzione di un intercolumnio del fronte esterno del Tempio di Zeus ad Agrigento, basata sul rilievo del Telamone oggi custodito presso il Museo Archeologico, sugli studi e i numerosi saggi di ricostruzione proposti dagli studiosi dal XVIII secolo fino alla metà dello scorso secolo e sulla analisi strutturale del Telamone ricostruito nel Museo. The drawings of the telamones, the giant statues placed the front of the Temple of Zeus in the archaeological area of Agrigento, have fascinated some of the most famous neoclassical architects in Europe. The virtual reconstruction of one intercolumnial of the Temple, based both on the range-based survey of…
