This is a complete and exhaustive review on the so-called holographic axion model—a bottom-up holographic system characterized by the presence of a set of shift symmetric scalar bulk fields whose profiles are taken to be linear in the spatial *** simple model implements the breaking of translational invariance of the dual field theory by retaining the homogeneity of the background geometry and therefore allowing for controllable and fast computations. The usages of this model are very vast and they are a proof of the spectacular versatility of the framework. In this review, we touch upon all the up-to-date aspects of this model from its connection with massive gravity and effective field theories, to its role in modeling momentum dissipation and elastic properties ending with all the phenomenological features and its hydrodynamic description. In summary, this is a complete guide to one of the most used models in Applied Holography and a must-read for any researcher entering this field.

Adaptive stray-light compensation in dynamic multi-projection mapping

引用

Computational Visual Media 2017年第3期3卷 263-271页

作者： Christian Siegl matteo Colaianni Marc Stamminger Frank Bauer Computer Graphics Group University of Erlangen-NurembergCauerstrasse 1191058 ErlangenGermany

Projection-based mixed reality is an effective tool to create immersive visualizations on real-world objects. Its wide range of applications includes art installations, education, stage shows, and advertising. In this work, we enhance a multi-projector system for dynamic projection mapping by handling various physical stray-light effects: interreflection,projector black-level, and environmental light in real time for dynamic scenes. We show how all these effects can be efficiently simulated and accounted for at runtime, resulting in significantly improved projection mapping results. By adding a global optimization step,we can further increase the dynamic range of the projection.

Towards a Formal Semantics for UML/MARTE State Machines Based on Hierarchical Timed Automata

引用

Journal of Computer Science & Technology 2013年第1期28卷 188-202页

作者： Yu Zhou Luciano Baresi matteo Rossi College of Computer Science Nanjing University of Aeronautics and Astronautics Nanjing 210016 China State Key Laboratory for Novel Software Technology Nanjing University Nanjing 210093 China Department of Electronics and Information Politecnico di Milano Milan 20133 Italy

UML is a widely-used, general purpose modeling language. But its lack of a rigorous semantics forbids the thorough analysis of designed solution, and thus precludes the discovery of significant problems at design time. To bridge the gap, the paper investigates the underlying semantics of UML state machine diagrams, along with the time-related modeling elements of MARTE, the profile for modeling and analysis of real-time embedded systems, and proposes a formal operational semantics based on extended hierarchical timed automata. The approach is exemplified on a simple example taken from the automotive domain. Verification is accomplished by translating designed models into the input language of the UPPAAL model checker.
