Moving Integrated Product Development to Service Clouds in the Global Economy - Proceedings of the 21st ISPE Inc. International Conference on Concurrent Engineering, CE 2014 | Year: 2014

Improvements in the design and manufacturing processes, and the related technologies that enable them, have led to significant improvements in product functionality and quality. However, the need for further improvements in these areas is needed due to increasing complexity of integrated product process development (IPD). Introduction of a new IPD project is more complex than most people realize and getting more complex all the time. Some of the complexity is due to rapidly changing and advancing technologies in underlying hardware and software, and the interplay of individual complex methods in system configurations. A strong IPD methodology, with intrinsically higher fidelity models to actualize the agile service-oriented design/manufacturing processes, is needed which can be continuously upgraded and modified. This paper describes a true service-oriented architecture that describes everything, anywhere, anytime as a service with the innovative service-oriented process expression (front-end services called exertions) and its dynamic and on-demand actualization (back-end service providers). Domain-specific languages (DSLs) for modeling or programming or both (mogramming) are introduced and their unifying role of front/back-end services is presented. Moving to the back-end of IPD systems front-end process expressions, that are easily created and updated by the end users, is the key strategy in reducing complexity of large-scale IPD systems. It allows for process expressions in DSLs to become directly available as back-end service providers that normally are developed by experts and software developers that cope constantly with the compatibility, software, and system integration issues that become more complex all the time. © 2014 The Authors and IOS Press.

In this paper we deal with the problem of identification of the dominating musical instrument in a recording containing simultaneous sounds of the same pitch. Sustained harmonic sounds from one octave of twelve instruments were considered. The training data set contains isolated sounds of two forms, one from selected musical instruments, and the other from the same mixed with artificial harmonic and noise sounds of lower amplitude. The test data set contains mixes of musical instrument sounds. A Support Vector Machine classifier was used for training and testing experiments, using a non-linear kernel. Additionally, we performed tests on data based on different recordings of instruments than those used in the training procedure described above. Results of these experiments are presented and discussed. © Springer Science + Business Media, LLC 2009. Source

In this paper, we present a new approach to evaluation of signal integrity that is based on signal energy density as a function of time and frequency, represented by its wavelet scalogram. Using signal integrity ratio and cumulative energy ratio, we illustrate signal integrity analysis with simulated examples, followed by the demonstration of their usefulness through analysis of experimental data of a real audio amplifier. These figures of merit represent the extent to which the integrity of a signal is diminished by the electromagnetic interference effects and/or nonlinear processes. © 1982-2012 IEEE. Source

Most work on activity recognition focuses on 2D image properties, holistic spatiotemporal representations, or space-time shapes in image domain rather than with 3D pose in a body-centric or world frame. Such techniques rely on advanced pattern recognition algorithms and interpreting complex behavioral patterns. In this work we posit that it is possible to achieve 3D pose tracking using videos recorded in multi-camera surveillance systems. We show experimental results that were obtained on PETS 2009 datasets. The estimation of the 3D articulated motion is achieved using a modified particle swarm optimization. © 2011 IEEE. Source
