Pełny tekst źródłaProcedural simulation is expending in orthopaedic and trauma surgery (OT) but in France its implementation amongst residents has not yet been reported. To enhance procedural training for medical students implies development of new teaching methods and simulators.A national survey was conducted amongst academic teachers and residents in OT. Results showed maximal potential was not reached. Main reasons were lack of funding and time. Both teachers and residents acknowledged the advantages of simulation.The traditional method to teach a procedure implies a continuous and uninterrupted demonstration of the entire procedure to the learner who is then expected to replicate it. To deconstruct the procedure into several key steps showed sequentially (micro-task method) could enhance learning of technical skills. Amongst a population of medical students undergoing simulation training on below elbow cast, immediately after the training session students trained by micro-task method demonstrated higher performance than by traditional method according various grading scales. Six months after the training, performance was decreased and equal in both groups. The only independent factor linked to better performance was a rotation in OT. To be effective, simulation training requires repeated practice and bedside teaching.The development of a procedural simulator for below elbow cast application and removal could enhance this training. A real size upper limb was modelized and constructed through three-dimensional printing. To objectively monitor the operator's gesture, different captors (pression, fracture and wrist mobility, temperature, cast saw vibrations, cast saw skin touch) were integrated to the simulator. Participants with different levels of expertise (novices and experts) tested the simulator. Although realism was deemed satisfactory in both groups, it did not mimic human's aspect perfectly, notably the soft tissues. The simulator appropriately recorded the participants' gesture and seemed to differentiate different levels of expertise. Its pedagogical interest remains to be evaluated

Pełny tekst źródłaProcedural modeling of virtual worlds is an active research field in computer science. A large amount of methods have been published in this field : modeling of plants, trees, buildings, cities or terrains, and aging and weathering simulations. In this context, changes of appearance are a very active research field too, due to the way they impact the realism of produced virtual scenes. This research focuses on a procedural method that can represent the changes of appearance as geometrical decorations (snowfall, ice growth, leaves deposits, etc.) on very big scenes with a high level of details. We first propose a hierarchical scene design based on a construction tree whose leaves are environmental objects, a new kind of objects that generate their own geometrical decorations. We then present an implicit formalism to define the environment that contains all the information needed to guide decorations generation. Finally, we detail four procedural methods for generating the geometrical decorations (snow, ice, grass, leaves) of the environmental objects

Pełny tekst źródłaWith constant development of technologies, computational and manufacturing capabilities increase, production methods evolve, and new techniques appear. As a result, the need for new materials with tailored, optimized properties for different applications arises. Periodic composites with tailored microstructure topology, called cellular metamaterials are extensively studied in this context. These structures are known for their remarkable mechanical properties, including high strength, lower weight, and increased energy absorption. The use of these materials allows to achieve improved physical properties or specific functional features and provides economical gain and ecological benefit.This thesis is dedicated to the development and analysis of methods for computer-aided design of materials with tailored mechanical properties. The mechanical metamaterials were studied through two different approaches: modelling periodic structures through a parameterized growth model and procedural noise functions. To tackle the challenge of obtaining near-regular microstructures with progressively varying properties, I proposed and studied a cellular material spawned by a growth process. The growth is parameterized by a 3D star-shaped set at each lattice point, defining the geometry that will appear around it. Individual tiles may be computed and used in a periodic lattice, or a global structure may be produced under spatial gradations, changing the parametric star-shaped set at each lattice location. Beyond free spatial gradation, an important advantage of this approach is that elastic symmetries can be intrinsically enforced. It is shown in this work how shared symmetries between the lattice and the star-shaped set directly translate into symmetries of the periodic structures' elastic response. Thus, the approach enables restricting the symmetry of the elastic responses -- monoclinic, orthorhombic, trigonal, and so on -- while freely exploring a wide space of possible geometries and topologies. I provide a comprehensive study of the space of symmetries and broad combinations of growth process parameters. Furthermore, I demonstrate through numerical and experimental results the expected responses triggered by the obtained structures.The second contribution of this thesis is a novel procedural pattern synthesis technique. This approach exhibits desirable properties for modeling highly contrasted patterns, that are well suited to produce surface and microstructure details. This approach defines a stochastic smooth phase field –- a phasor noise –- that is then fed into a periodic function (e.g. a sine wave), producing an oscillating field with prescribed main frequencies and preserved contrast oscillations. I present in this thesis a mathematical model, that builds upon a reformulation of Gabor noise in terms of a phasor field that affords for a clear separation between local intensity and phase. In particular, I study the behavior of phasor noise in terms of its power spectrum. Hence, a comparative theoretical study of phasor noise was performed in order to gain understanding of links between its properties and parameters

Pełny tekst źródłaWith the construction and development of the smart city, how to construct the realistic 3D model of the large-scale city buildings quickly and efficiently which becomes the research hotspot. In this thesis, a novel 3D modeling approach is proposed to quickly and efficiently build 3D model of large-scale city buildings based on shape grammar and facade rule modeling. Building Information Model (BIM) is an important technical means to enhance the construction industry, for the city building design and construction, how to better research and application of BIM technology which is the key, in this thesis City Building Integrated Information Model (CBIIM) is specified to manage the information of building lifecycle effectively and realize the information sharing and exchanging. This thesis has studied the acquisition and processing of the modeling data. Google Earth and ArcGIS software are mainly used to acquire and process image-maps data and elevation-maps data of the target area, these two kinds of data match and overlay, which can generate 3D city terrain data with geographic location information. Then OpenStreetMap is used to acquire road data of the target area, and it can be optimal processed to the necessary road network by JOSM software. 3D laser scanning technology is used to collect building surface texture images and create the point clouds model of the target architecture modeling so as to get the modeling dimensions by measurement. On this basis, this thesis mainly has studied the principle and the process of CGA rule to create building models, and studied the method that can separate architectural elements using image segmentation to generate CGA rule automatically and to create building model furtherly. Thus 3D building models have been established in the CityEngine software using CGA rules and facade modeling technology. This thesis has specified the City Building Integrated Information Model (CBIIM) based on BIM. The city building information are classified and integrated, and the building and component was described with the IFC standard, in order to manage the informations of building lifecycle effectively. This thesis studies the integrated information association model technology, that it can realize standardized component design with associated features and intelligent building design with associated parameters in knowledge rules combined with IFC. The construction simulation technology is studied. The knowledge rules in the integrated information model provide a reliable reference for the construction simulation, and the simulation scene is created through the invoking the integrated information model, thus the construction simulation process is completed by the program. Taking Baoshan Campus of Shanghai University as an example, the modeling process of the whole scene is illustrated, and the modeling steps of all kinds of 3D objects are described in detail to solve the specific problems in the actual modeling process. Thus the feasibility and validity of the procedural intelligent modeling approach are verified. Taking the dormitory of Shanghai University as an example, a simulation scene and the simulation model were created by the integrated informations, combined with the relevant construction information the construction simulation was completed by the program. Thus the feasibility and validity of the CBIIM are verified

Pełny tekst źródłaWorld urban population is growing fast, and so are cities, inducing an urgent need for city planning and management.Increasing amounts of data are required as cities are becoming larger, "Smarter", and as more related applications necessitate those data (planning, virtual tourism, traffic simulation, etc.).Data related to cities then become larger and are integrated into more complex city model.Roads and streets are an essential part of the city, being the interface between public and private space, and between urban usages.Modelling streets (or street reconstruction) is difficult because streets can be very different from each other (in layout, functions, morphology) and contain widely varying urban features (furniture, markings, traffic signs), at different scales.In this thesis, we propose an automatic and semi-automatic framework to model and reconstruct streets using the inverse procedural modelling paradigm.The main guiding principle is to generate a procedural generic model and then to adapt it to reality using observations.In our framework, a "best guess" road model is first generated from very little information (road axis network and associated attributes), that is available in most of national databases.This road model is then fitted to observations by combining in-base interactive user edition (using common GIS software as graphical interface) with semi-automated optimisation.The optimisation approach adapts the road model so it fits observations of urban features extracted from diverse sensing data.Both street generation (StreetGen) and interactions happen in a database server, as well as the management of large amount of street Lidar data (sensing data) as the observations using a Point Cloud Server.We test our methods on the entire Paris city, whose streets are generated in a few minutes, can be edited interactively (<0.3 s) by several concurrent users.Automatic fitting (few m) shows promising results (average distance to ground truth reduced from 2.0 m to 0.5m).In the future, this method could be mixed with others dedicated to reconstruction of buildings, vegetation, etc., so an affordable, precise, and up to date City model can be obtained quickly and semi-automatically.This will also allow to such models to be used in other application areas.Indeed, the possibility to have common, more generic, city models is an important challenge given the cost an complexity of their construction
Abdul, Karim Ahmad. "Procedural locomotion of multi-legged characters in complex dynamic environments : real-time applications". Thesis, Lyon 1, 2012. http://www.theses.fr/2012LYO10181/document.
Pełny tekst źródłaMulti-legged characters like quadrupeds, arachnids, reptiles, etc. are an essential part of any simulation and they greatly participate in making virtual worlds more life-like. These multi-legged characters should be capable of moving freely and in a believable way in order to convey a better immersive experience for the users. But these locomotion animations are quite rich due to the complexity of the navigated environments and the variety of the animated morphologies, gaits, body sizes and proportions, etc. Another challenge when modeling such animations arises from the lack of motion data inherent to either the difficulty to obtain them or the impossibility to capture them.This thesis addresses these challenges by presenting a system capable of procedurally generating locomotion animations fordozens of multi-legged characters in real-time and without anymotion data. Our system is quite generic thanks to the chosen Procedural-Based techniques and it is capable of animating different multi-legged morphologies. On top of that, the simulated characters have more freedom while moving, as we adapt the generated animations to the dynamic complex environments in real-time. Themain focus is plausible movements that are, at the same time,believable and fully controllable. This controllability is one of the forces of our system as it gives the user the possibility to control all aspects of the generated animation thus producing the needed style of locomotion

Pełny tekst źródłaNuclear fuel cladding tubes resistance against high temperature oxidation during accident conditions is crucial because it means protecting the first containment barrier. This can be done by coating the inner wall of the cladding tube with CVD processes, which are most likely to do so. More specifically, we used DLI-MOCVD to grow chromium based (Cr(S), metallic crystalline chromium) and chromium carbides based (amorphous chromium carbides CrxCy, recycled CrxCy, silicon doped CrxSizCy) coatings, known for their good oxidation resistance. The coating process was optimized using numerical modelling to improve coatings performance. A reaction kinetics model of the deposition process of amorphous CrxCy coatings was adjusted and validated after the identification of the chemical mechanism. It was also shown that the liquid solution containing organometallic precursor (bis(arene)chromium) and solvent (toluene) could be directly recycled, thereby increasing the industrialization potential of such process. Physical, chemical and structural properties of coatings deposited with this process were characterized. A study of the coatings mechanical properties has also been undertaken. It shows that compared to related coatings grown with other processes, those deposited by DLI-MOCVD exhibit a particularly high hardness (up to 30 GPa), compressive residual stresses, good adhesion with the substrate and finally a different abrasive wear resistance depending on the temperature. The assessment of their oxidation resistance at 1200 °C revealed excellent performances of amorphous chromium carbides coatings, which can delay catastrophic oxidation up to two hours with only a 10 µm thickness. All the other coatings only increase the thermal resistance of zircaloy substrates
