While previous research in academia points to the ability of Natural User Interfaces (NUIs) and low-cost display devices to help users better understand a design, there does not exist much research on how these devices can be integrated into existing legacy code used by engineering and design firms. The lack of commercial engineering software that integrates NUIs and low-cost display devices, like the Oculus Rift, can be attributed to the fast changing device market and the lack of awareness many engineering software makers show in emerging interaction paradigms. The lack of work in the area of integrating low-cost immersion devices ...


Ultrahard Polycrystalline Cubic Boron Nitride Composite Through Hybrid Laser/Waterjet Heat (Lwh) Treatment, Jingnan Zhao, Pranav Shrotriya Jan 2016

Ultra-hard materials that are chemically inert and thermally stable at high temperatures are desirable for enhancing machining and wear performance in demanding chemical and thermal environments. Single and polycrystalline diamonds are the hardest tool materials; however, at high temperatures, diamond reacts with ferrous alloys, losing its chemical inertness and thermal stability. In contrast, cubic boron nitride (cBN) has exceptional chemical and thermal stability but has much lower hardness (35-45 GPa). Increasing the hardness of BN is expected to fill the property gap in state-of-the-art tool materials as shown and to generate huge industrial interest for meeting the stringent design requirements ...

Current characterization methods of the so-called Bulk Heterojunction (BHJ), which is the main material of Organic Photovoltaic (OPV) solar cells, are limited to the analysis of global fabrication parameters. This reduces the efficiency of the BHJ design process, since it misses critical information about the local performance bottlenecks in the morphology of the material. In this paper, we propose a novel framework that fills this gap through visual characterization and exploration of local structure-performance correlations. We also propose a formula that correlates the structural features with the performance bottlenecks. Since research into BHJ materials is highly multidisciplinary, our framework enables ...


Effect Of Sample Aging On The Accuracy Of The International Energy Agency's Tar Measurement Protocol, Ming Xu, Robert C. Brown, Glenn Norton Jan 2006

Effect Of Sample Aging On The Accuracy Of The International Energy Agency's Tar Measurement Protocol, Ming Xu, Robert C. Brown, Glenn Norton

Mechanical Engineering Publications

The Working Group of the Biomass Gasification Task of the International Energy Agency (IEA) Bioenergy Agreement has developed a protocol for sampling and analysis of tar and particulates from biomass gasifiers, which is commonly accepted as a standard for reliable measurement of tar in producer gas. The methodology is dependent upon dissolving tar in a solvent for subsequent recovery by evaporation or distillation. This paper investigates whether storage of the tar/solvent sample prior to analysis affects the accuracy of the tar measurement. On the basis of the results of this study, we recommend that samples be analyzed within a ...


Discrete Event Simulation Implemented In A Virtual Environment, Jason Kelsick, Lori Buhr, Cheryl Moller, Judy M. Vance Sep 2003

Discrete Event Simulation Implemented In A Virtual Environment, Jason Kelsick, Lori Buhr, Cheryl Moller, Judy M. Vance

Mechanical Engineering Publications

Virtual reality (VR) technology provides a human-computer interface that allows participants to interact naturally with digital objects which are represented as three-dimensional images that occupy positions in a three-dimensional world. Related to problems of engineering design and manufacturing, this new technology offers engineers the ability to work with computer models in a three-dimensional, immersive environment. This paper describes a virtual reality application where the results of a discrete event simulation of a manufacturing cell are integrated with a virtual model of the cell to produce a virtual environment. The program described in this paper, the VRFactory, combines results from a ...
