Mobile IPv6 enables mobile node to roam transparently in any network. It shows good performance for macro mobility but it is not proper for supporting micro mobility because of large latency. Accordingly, IETF (Internet Engineering Task Force) mobileip WG(Working Group) suggests Fast Handover Protocol and HMIPv6(Hierarchical Mobile IPv6) for micro mobility management. However, HMIPv6 has some p...

This paper aims at developing a force-guided microassembly technology with in-situ flexible polyvinylidene fluoride (PVDF) beam force sensing and hybrid force/position control based on an infinite dimensional model of the flexible sensor structure. Besides the designed 1-D PVDF cantilever based microforce sensor, as the soft sensor structure itself is installed at the free end of micromanipulat...

This paper reports on our research in developing a micro power generation system based on gas turbine engine and piezoelectric converter. The micro gas turbine engine consists of a micro combustor, a turbine and a centrifugal compressor. Comprehensive simulation has been implemented to optimal the component design. We have successfully demonstrated a silicon-based micro combustor, which consist...

Micro assembly involves the assembly of micronsized devices. Given the complexity of this domain, the role of virtual environments becomes important as they provide a basis to propose and compare assembly alternatives virtually prior to physical assembly. This paper proposes an integrated approach which includes the use of virtual reality-based assembly environments that interface with physical...

In this communication, we describe a novel methodology for single bacterial detection based on micro-channel gating and involving the use of microelectrodes in a micro-channel for detection of target cell capture. The sensors designed have been shown to be capable of electrical detection of the target cells at the single cell level.

Micro-channels are made over the Ag+/Na+ ion-exchanged soda-lime glass surface by interaction of an intense Ar+ laser beam and the silver ions inside the glass matrix. The Ar+ laser beam reduces the Ag+ ions inside the matrix. The Ag+ atoms aggregate into silver nano-clusters around the interaction area, inside the glass matrix. Aggregation of the silver atoms and the thermal effects of the int...

Novel micro-structured string-reactor designed as catalytically active wires placed in parallel into a tube was developed. The small diameter of the channels (∼100 m) leads to a short radial diffusion time, a narrow residence time distribution (RTD), and a low pressure drop. This reactor was applied for the oxidative steam-reforming of methanol (OSRM) to produce hydrogen in autothermal mode for...
