TL;DR: In this paper, a multi-objective optimization problem consisting of an integration among finite element (FEM) numerical simulation, Response Surface Methodology (RSM) and Monte Carlo Simulation (MCS) method is proposed to deal with the scattering of the final part quality due to inner variability of such operations.

TL;DR: In this article, a method which extends the use of the well established chart for the design of solar shading devices was developed, which provides a quantitative proportion of the opening's area which is exposed at any given time to direct solar radiation, in addition to the binary answer returned by the old chart whether any part of an opening is exposed or not exposed to such radiation at all.

TL;DR: Design tools for circular PCF have been developed to analyze the vector modes by giving the modal map of the cutoff condition of eigenmodes and colormap of minimum effective refractive index separation between different eigenModes.
Abstract: We propose a design tool for the family of circular photonic crystal fiber (C-PCF) supporting orbital angular momentum modes. The calibrated normalized parameters for the C-PCF family are presented. The information about the cutoff condition of modes, the number of modes supported in fibers, and the effective index difference between adjacent modes can be obtained by using the design tool. Also, the mode properties, such as confinement loss, effective mode area (Aeff), and spin-orbital coupling are analyzed using the design tool. At the end of paper, we also give some fiber design examples by using the design tool.

TL;DR: In this paper, a 5 kW pico propeller turbine has been tested at a test site in Peru and Computational Fluid Dynamics (CFD) has been used to obtain overall performance data for the turbine and assist in the design of a new rotor.
Abstract: A research project is currently being undertaken in collaboration with Practical Action (ITDG) to develop a standard design procedure for pico propeller turbines that can be manufactured locally in developing countries. A 5 kW demonstration turbine has been set up at a test site in Peru and Computational Fluid Dynamics (CFD) has been used to obtain overall performance data for the turbine and to assist in the design of a new rotor. It was found that an incorrect matching between the turbine rotor design and the available flow rate at the site significantly affected the turbine operation and in order to provide an acceptable performance it was possible to adjust just the runner design and operating speed of the turbine. The paper will present the initial CFD and field test results, and discuss the process by which computational fluid modelling has been used as an appropriate design tool.

TL;DR: It is shown that building neural networks allows one to train a surrogate model to accelerate the structural performance assessment of various possible structural forms without going through a significantly slower process of geometric form-finding.
