We present MagicToon, an interactive modeling system with mobile augmented reality (AR) that allows children to build 3D cartoon scenes creatively from their own 2D cartoon drawings on paper. Our system consists of two major components: an automatic 2D-to-3D cartoon model creator and an interactive model editor to construct more complicated AR scenes. The model creator can generate textured 3D cartoon...
Water and thermal management have been identified as technical hurdles to the successful implementation of low-temperature polymer electrolyte membrane (PEM) fuel cell (PEMFC) power systems. In low-power applications, miniature PEMFCs show significant promise as a competitor to lithium-ion batteries. Significant design work is underway to improve the specific power and energy densities of these fuel...
In this work, by numerical simulation using a commercial CFD (computational fluids dynamics) code, were obtained the velocity fields and thermal fields, inside of an indirect type natural convection solar food-dryer. For validating the numerical simulation, was developed an experimental model of an indirect type natural convection solar food-dryer. The food-dryer was instrumented with thermocouples...
In the last few decades research efforts were conducted to grasp good understanding about the origin of equiaxed and columnar grains formed during solidification. The morphological evolutions such as globular/cellular to dendritic or columnar-to-equiaxed transition were generally studied. Correspondingly, some empirical models were introduced. Nevertheless, no sufficient attention was paid to incorporation...
In this paper, the concept of spherical image model is proposed, along with the algorithm of generating the spherical image of the model. Experimental results show that the algorithm meets real-time requirements.
This paper discusses techniques to develop the database of civil aviation Air Traffic Control (ATC) Tower scene database and optimize approaches of 3D model by virtue of the professional modeling tool -MultiGen Creator. The ATC Tower visual simulation system is established combined with Vega Prime. However, excessive amount of data make the system not run smoothly, thus, a number of the corresponding...
Engine room of a ship is an environment scattered numbers of components. Pipe-routing arrangement should meet various requirement or constraints referring to either properties of individual components or relationships between components. The models of environment and components must be simplified by appropriate method to ensure an accurate and effectual design. An approach was proposed to construct...
Tidal bore is a peculiar nature phenomenon which is caused by the lunar and solar gravitation. Based on the physical characters of tidal bores, in this paper we propose a novel method to model and render this phenomenon, especially the tidal waves in Qiantang estuary. According to Boltzmann equation for tidal waves, we solve it with the novel triangle mesh of kinectic flux vector splitting (KFVS)...
In order to be an effective tool for driver evaluation and education, driving simulators need to be better designed to reduce simulator sickness. In this paper, we expose platform design, description and the modeling aspects of a 2 DOF low cost motion platform allowing the restitution of the longitudinal and yaw movements. To enhance the drive immersion in the virtual world, a haptic feedback steering...
In this paper the scope and type of models and simulations used in defence system acquisition are reviewed. The principles of Simulation-Based Defence Acquisition are presented and discussed in the context of the changes and challenges of complex systems acquisition management. The paper also presents different case studies that illustrate to what extent modelling and simulation were used in major...
The dynamic model of a 3D overhead crane system is established by utilizing Lagrangepsilas equation. In the model, not only the motion of the trolley in horizontal plane, but also the variation of the rope length is considered, to provide a precise description for the dynamic performance of the system states. Furthermore, the main nonlinear disturbances existing in the environment, such as the dynamic...
