This paper reports pedagogical experiences and educational techniques in the field of Mechanics of Structures (Mechanical Engineering degree), resorting to computational tools.Several aspects are addressed, covering CAD (Computer-Aided Design) modelling systems to CAE (Computer-Aided Engineering) solutions, in terms of analysis and validation of me
This paper aims to analyze Internet-based streaming video service in the communication media with variable bit rates.The proposed scheme on Dynamic Adaptive Streaming over HTTP (DASH) using the internet network that adapts to the protocol Hyper Text Transfer Protocol (HTTP).DASH technology allows a video in the video segmentation into several packa
Aiming at the problems of low contrast and low definition of fog degraded image, this paper proposes an image defogging algorithm based on sparse representation.Firstly, the algorithm transforms image from L-CARNITINE RGB space to HSI space and uses two-level wavelet transform extract features of image brightness components.Then, it uses the K-SVD
Abstract Interspecific hybridization has been fundamental in plant evolution.Nevertheless, the fate of hybrid zones throughout the generations remains poorly addressed.We analyzed a pair of recently diverged, interfertile, and Hand Axes sympatric Petunia species to ask what fate the interspecific hybrid population has met over time.We analyzed the
