Rapid prototyping (RP) techniques are a group of advanced manufacturing processes that can produce custom made objects directly from computer data such as Computer Aided Design (CAD), Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) data. Using RP fabrication techniques, constructs with controllable and complex internal architecture with appropriate mechanical properties can be ach...

Die Spezi kation analoger und analog digitaler Systeme durch informelle Mittel wie Blockdia gramme und umgangssprachliche Beschreibungen ist durchaus ublich Derartige Spezi kationen k onnen zu schwerwiegenden Entwurfsfehlern f uhren die erst sp at etwa beim Vorliegen des fertigen Produktes entdeckt werden Dar uberhinaus k onnen informelle Spezi kationen nur schwer als Ausgangsbasis eines automa...

Zusammenfassung—Zum Testen verteilter bzw. vernetzter Systeme existieren zahlreiche Werkzeuge, etwa [1]–[3], welche für das Rapid Prototyping und die Fehler-Rekonstruktion unerlässlich sind. Durch verschieden stark abstrahierte Modelle lassen sich auf diese Weise, bereits früh in der Entwicklung verteilter Systeme, Aussagen über Performanz, Konsistenz und Korrektheit von Netzwerkprotokollen tre...

rapid prototyping (rp) is a technique of manufacturing parts by the additive layer manufacturing technology; where, a three-dimensional (3d) model created in a computer aided design (cad) system is sectioned into 2d profiles, which are further constructed by rp layer by layer. its use is not limited to industrial or engineering fields and has extended to the medical field for the manufacturing ...

We begin with our definition of a prototype and then discuss prototypes as design artifacts, introducing four dimensions for analyzing them. We then discuss the role of prototyping within the design process, in particular the concept of a design space, and how it is expanded and contracted by generating and selecting design ideas. The following sections describe specific prototyping approaches:...

Over the last decade, rapid prototyping (RP) technologies have continued to advance in all aspects of operation and application. From continuously advanced materials and processes development to more hard-core manufacturing uses, the RP realm has stretched considerably past its original expectations as a prototyping capability. This paper discusses the unique applications for which NASA has cho...

myoepitheliomas are benign tumors which account for less than 1% of all salivary gland tumors. in this article, we report the clinical, pathologic, and immunohistochemical features of plasmacytoid myoepithelioma of the hard palate in a 73-year-old man having a painless hard palate mass with progressive growth for one month who was admitted in alzahra hospital of isfahan university of medical sc...
