Generation of Functional Interface by Micro/Meso Mechanical Manufacturing (M4 process) technology

NEXT
PREV
Features

Recently, micro parts, such as glass waveguide, micro lens array and holographic optical element, made from materials other than silicon are increasingly demanded. The sizes of the micro parts are below 1 mm (so-called sub-millimeter size), and the shapes are complex. As high hardness, high brittleness and high melting point predominate most of these materials, micro parts of these materials are particularly difficult to be machined, even by lithography techniques, laser beam and electron beam. Additionally, high efficiency and low cost micro manufacturing method is highly expected. Our lab concentrates on promoting innovations of mechanical manufacturing technologies to realize micro fabrication, especially on developing new processing principle of Micro/Meso Mechanical Manufacturing (M^4 process) at the frontier of manufacturing technology.
The M^4 process includes: 1. Aspherical micro-grinding, 2. Micro aspherical polishing 3. Micro cutting of aspheric micro lens array, 4. Micro abrasive jet machining (AJM), 5. Micro powder jet deposition (PJD), 6. Micro ultrasonic machining, 7. Micro Electrical discharge machining (EDM), 8. Micro laser machining.

OpenEnergySim: A Virtual World to Assess CO2 Emission

NEXT
PREV
Features

Intelligent Transport System (ITS) strategies can significantly reduce CO2 emissions of vehicles.
However, there is currently no low-cost yet effective method to investigate the impact of enegry-saving ITS measures on driving behavior. Further, there is no convenient collaboration platform to compare the results of such "green" ITS strategies at an international level.
Therefore, we implement OpenEnergySim, an online multi-user three-dimensional (3D) simulation space, which can serve three functions in one single consistent environment:
1. Visualization of microscopic traffic and CO2 emissions
2. Immersive driving of users in a simulated traffic network, where ITS measures can be applied and tested interactively
3. A shared real-time collaboration space aimed at international partners for studying and comparing the effects of green ITS strategies on CO2 emission reduction
OpenEnergySim can provide a unique platform for green ITS which fosters international collaboration and facilitates harmonization of models in the transport domain.
