Virtual Prototyping

When it comes to prototyping, there’s quite a bit of debate over low
fidelity vs. high fidelity, paper versus digital. As you’ll discover in
this book, each tool has its place depending on personal preferences
and design stage.
We’ll share expert advice, design theories, prototyping tips, and
screenshots of prototypes created using the most popular methods.
For beginners, you’ll learn the many different tactics and processes
for prototyping and why prototyping is required for crafting memorable
product experiences. For more advanced readers, you’ll learn
how to select the right fidelity and prototyping tool and where prototyping
is headed in the future.
You’ll find that we’ve also analyzed prototyping best practices from
companies like Buffer, Apple, Google Ventures, ZURB, Groupon,
IDEO, Virgin America, and dozens others. We’ve made this book
Introduction
A quick note from the authors
as practical as possible and included advice based on our own prototyping
experience at UXPin.
Prototyping helps unveil and explore human needs, opening the
door to insightful interaction and more empathetic design solutions.
If a wireframe is worth 1000 words, then a prototype is worth at
least 10,000.
We’d love your thoughts on what we’ve written, and feel free to
share with anyone who might find this helpful.

Computer-aided technologies (CAx) mean the use of computer technology to aid in the design, analysis and manufacture various products. International Journal of Computer-Aided technologies (IJCAx) is an open access, peer-reviewed journal that publishes articles which contribute new results in all areas of Computer Aided technologies such as CAD, CAM, CAIM,CAR, CARD, CASE etc. The journal focuses on all technical and practical aspects of Computer Aided technologies. The goal of this journal is to bring together researchers and practitioners from academia and industry to focus on advanced CAx tools and establishing new collaborations in these areas. Authors are solicited to contribute to this journal by submitting articles that illustrate research results, projects, surveying works and industrial experiences that describe significant advances in all Computer Aided technologies

The constant demand for higher efficiency and power density and lower costs of power electronics systems could be met by application of new topologies and/or modulation schemes and future wide-band gap semiconductor technology. However, the performance of state-of-the-art systems also could be improved significantly by multidomain/objective optimisation, i.e. by assigning overall optimal values to the design variables in the course of the design process. In order to perform such an optimisation first a comprehensive mathematical model of the main converter circuit has to be established, including thermal component models and the measures for DM and CM EMI filtering. Based on this model, an optimisation for multiple objectives, as e.g. efficiency and power density, can be performed. The optimisation makes best use of all degrees of freedom of a design and also allows to determine the sensitivity of the system performance on base technologies like Figures of Merit of the power semiconductors or properties of the magnetic core materials. Furthermore, different topologies can be easily compared and inherent performance limits can be identified.
In the paper, analytical approaches for designing the main functional elements of a power electronics converter are described and arranged to a linear design process in a first step. Moreover, the linking of the component models, i.e. of the electric, magnetic, thermal and thermo-mechanic design domains and an overall optimisation of the respective design variables based on the linked models is discussed. Finally, the coupling of the different domains and for example the utilisation of electrical equivalent circuits for implementing these couplings are investigated.

This paper presents the development and implementation of integrated intelligent CAD (computer aided design) system for design, analysis and prototyping of the compression and torsion springs. The article shows a structure of the developed system named Springs IICAD (integrated intelligent computer aided design). The system bounds synthesis and analysis design phases by means of the utilization of parametric 3D (three-dimensional) modeling, FEM (finite element method) analysis and prototyping. The development of the module for spring calculation and system integration was performed in the C# (C Sharp) programming language. Three-dimensional geometric modeling and structural analysis were performed in the CATIA (computer aided three-dimensional interactive application) software, while prototyping is performed with the Ultimaker 3.0 3D printer with support of Cura software. The developed Springs IICAD system interlinks computation module with the basic parametric models in such a way that spring calculation, shaping, FEM analysis and prototype preparation are performed instantly.

Abstract: In this contribution we discuss some questions relative to the use of New Technologies in the scope of the registry, preservation and spreading of Archaeological Heritage. In particular, through the analysis of an example, we display some advantages and disadvantages of using a 3D digitizer (Konica Minolta Non-Contact 3D Digitizer VI-910) in small archaeological objects, as well as the application of the 3-Dimensional Photopolymers Printing System by means of a 3D printer (Objet EDEN 500VTM).

The paper summarizes a new modeling procedure for 3D virtual design of EMI filter circuits. The proposed method, based on the coupling of the Partial Element Equivalent Circuit (PEEC) and Boundary Integral Method (BIM) methods, extends the standard PEEC approach for modeling in the presence of magnetic materials, hence allowing the PEEC-based modeling of toroidal EMI filter inductors. The PEEC-BIM

The use of computational fluid dynamics (CFD) software in many materials processing industries has grown tremendously in recent years. Computational fluid dynamics has been widely utilized for conducting virtual experiments, prototype testing, and parametric studies. Analysis using CFD complements and reduces physical testing, and it can result in a significant time and cost savings. In this article, the application of CFD to a variety of materials-processing problems is presented, with examples taken from the steel, aluminum, glass, semiconductor, and polymer processing fields.
