For creating a cel animation, the animators often use 3D character models to add some effects on the character or to generate intermediate images between the key frames. However, it is troublesome and time-consuming task to create a 3D model. In this paper, we present an easy-to-use approach for creating a set of 3D models from the user-specified strokes on a 2D image sequence. The created 3D m...

Automatic reconstruction of 3D models from video sequences requires selection of appropriate video frames for performing the reconstruction. We introduce a complete method for key frame selection that automatically avoids degeneracies and is robust to inaccurate correspondences caused by motion blur. Our method combines selection criteria based on the number of frame-to-frame point corresponden...

This paper explores the sustainability aspects of binders used in concrete 3D printing. Firstly, a prospective approach to conduct sustainability-assessment based on life cycle printed structures is presented, which also highlights importance considering functional requirements mixes for The potential material production phase emphasized enhance 3DCP by reducing embodied impacts. literature dif...

Animals are widespread in nature and the analysis of their shape and motion is important in many fields and industries. Modeling 3D animal shape, however, is difficult because the 3D scanning methods used to capture human shape are not applicable to wild animals or natural settings. Consequently, we propose a method to capture the detailed 3D shape of animals from images alone. The articulated ...

We present a novel approach to reconstruct and track articulated objects, specifically humans, in 3D from monocular videos for action recognition, by combining techniques from both image processing and 3D computer animation. The goal is to establish a system that is able to recognize basic actions (like walk, run) from frame to frame in a scene with more than one person. In a first step a featu...

an experimental program was conducted to determine the effects of geosynthetic reinforcement on mitigating reflection cracking in asphalt overlays. the objectives of this study were to asses the effects of geosynthetics inclusion and its placement location on the accumulation of permanent deformation. to simulate an asphalt pavement overlaid on top of a crack in a concrete or asphalt pavement, ...

Three dimensioned finite element analysis were conducted on concrete block paving. In order to verify the calculated results, an experimental case study was analyzed. Good agreement was observed between the measured and the calculated results. Based on the finite element analysis results and available failure models, comprehensive design charts were developed for port and industrial pavement wh...

To assess the performance criteria of the reinforced-concrete, five-storey residential buildings common in Iran, an &#10experimental study in the structural laboratory of the University of Tehran has been conducted. The test program includes cyclic and monotonic load tests of six beams that represent three-to-five storey buildings with rigid frame structures. Using definitions given in FEMA-356...

In recent years, destructive earthquakes have shown the deficiencies of the existing buildings. One of the most effective mechanisms for dissipating the earthquake energy is inelastic deformation of the steel components. The objective of this research is to study the application of metallic dampers for dissipation of the earthquake energy and to investigate the behavior of concrete structures i...
