The present work, is focused on the study of beam type structures made of agro waste composite materials, namely of sawdust and palm kernel shell, and comprises two parts. A first one where the static and dynamic behavior characterization of the structure is carried out using a first order shear deformation theory approach, considering the influence of different fiber constituent's percentages. In the second part, a few structural optimization case studies are considered concerning different objective functions and constraints, using sequential quadratic programming technique. Both, analysis and optimization studies were developed on a symbolic computation platform. According to the results obtained in the case studies carried out, it can be concluded that they respect the trends that would be expected, taking into account the nature of the parameters studied: the length to thickness ratio, the boundary conditions and the percentages of the reinforcement agents' mixtures. A final aspect that is worth mentioning is related to the advantages of using such type of platform in research work, which enables for an integrated development and simulation environment, where the libraries access and the functionalities available, enable a more expedite and perceptive way of achieving results.
Dance is an art form considered as a form of language since it can sometimes reflect a culture of a population or even a celebration that accompanies humanity from its earliest times and which requires of the dancer a high physical and emotional dexterity. However, it is expected that the dancer performs rigorous and repetitive technical movements that often lead to painful injuries.Due to the high number of injuries, it is essential to study and analyze base movements for this type of dance in order to prevent injuries and to optimize the dancer's choreography and productivity. These movements are precedents of more complex movements. In this work, the study of a basic jump, the Grand Jeté, using biomechanical techniques is carried out by finding the kinematics of the movement.For the data collection, three dancers (2 females and 1 male) voluntarily participated and the movements were capture using a 2nd Generation Kinect camera that allows the capture of 3D movement. The biomechanical analysis was performed for the movement recorded and the results were presented to show the adequacy of the methodology proposed. By using this methodology, the aim is to characterize the movement and to be able to promote a better understanding of everything involved in the performance of the movement with the performers and teachers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
