People’s daily lives provide them with memories and records that they often want to review later. They must expend time and effort to record these experiences manually for future retrieval. To address this issue, applications that automatically capture details of a live experience and provide future access to that experience have become an increasingly common theme of research in ubiquitous com...

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...

To support the rapid development of pen-based structured diagram editors, we propose a framework for describing such editors. The framework uses grammar to describe the context, i.e., the positional relationship between handwritten strokes and other objects, which can be used to interpret ambiguous results of pattern matching, and to describe the syntax of the target diagrams. We implemented th...

We present a hardware-software cosimulation environment for heterogeneous systems. To be an efficient system verification environment for the rapid prototyping of heterogeneous systems, the environment provides following features: interface transparency, smooth transition to cosynthesis, simulation acceleration, and integrated user interface and internal representation. Among them, the first tw...

A new approach to the refixturing-free sculpturing of large, arbitrarily complex shapes has been developed. Based on an enhanced accessibility analysis of the target shape, a reduced set of candidate machining orientations is determined. Then, machining takes place at very close distance between the tooling machinery and the part, thus achieving effective material removal in complex regions. Mi...

Paper presents research results of the parts accuracy after manufacturing with used Rapid Prototyping technology in context of the possible use of multi-directional layers disposition. Errors of the model by production were analyzed in two categories: external and internal model errors. External errors of models production include: conversion error, staircase error and error of slicing into lay...

We propose in the paper a process, based on the use of a high velocity, electric arc metal spray thoroughly atomized on a master model in order to make a shell. The mold is realized by placing the sprayed alloy into a frame and reinforcing it with appropriate material. The first part of the paper presents briefly the main rapid prototyping and tooling techniques used in industry. We then descri...

MeVisLab is a research and rapid prototyping platform for medical image processing developed by MeVis Medical Solutions AG and Fraunhofer MEVIS. We present an object-oriented approach for developing applications using MeVisLab and Python. Our approach simplifies the development of scripting intensive and complex applications for medical image processing. The program flow becomes clearer and the...

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 ...
