this paper demonstrates a preliminary investigation of geometry, function and its relation to dfx principles, namely dfm (design for manufacturing). this is the starting point for research on the development of an expert system that assesses design goals along dfx principles in a feature-based cad environment. there is a need for a deeper level of understanding of the relationship between geome...

the steps taken in designing a loop reactor for bulk propylene polymerization are discussed. the roles played by several parameters like particle growth factor, catalyst activity and solid fraction on reactor volume at different operating conditions are investigated. at first, based on a fixed production capacity and specific rate of catalyst, reactor volume is determined. next, the length and ...

This study includes a global sensitivity analysis of the water productivity model AquaCrop. The study rationale consisted in a comprehensive evaluation of the model and the formulation of guidelines for model simplification and efficient calibration. The global analysis comprehended a Morris screening followed by a variance-based Extended Fourier Amplitude Sensitivity Test (EFAST) under diverse...

RoboAnalyzer is a software based on 3Dmodel of robots. It was developed primarily for teaching and learning of robot mechanics, although it is robust enough for the use by researchers as well. The motive behind the development of RoboAnalyzer was mainly to help teachers and students get started with teaching/learning of robotics using template-based skeleton models or CAD models of serial robot...

We present an integrated design and marketing approach to facilitate the generation of an optimal robust set of product design alternatives to carry forward to the prototyping stage. The approach considers variability in both (i) engineering design domain, and (ii) customer preferences in marketing domain. In the design domain, the approach evaluates performance and robustness of a design alter...

gyroscopes are used as rotation rate sensors. conventional gyroscopes are heavy and bulky, which creates important problems regarding their usage in different applications. micro-gyroscopes have solved these problems due to their small size. the beam micro-gyroscope is one of the popular types of inertial sensors. their small dimensions and low energy consumption are key reasons for their popul...
