Spiral Methanol to Hydrogen Micro-Reformer for Fuel Cell Applications

Optimal Operation of Doubly-fed Induction Generator used in a Grid-Connected Wind Power System

In this paper, a wind power system based on a doubly-fed induction generator (DFIG) is modeled and simulated. To guarantee high-performance control of the powers injected into the grid by the wind turbine, five intelligent super-twisting sliding mode controllers (STSMC) are used to eliminate the active power and current ripples of the DFIG. The STSMC controller is a high-order sliding mode cont...

Data reconciliation and optimal operation of a catalytic naphtha reformer

The naphtha reforming process converts low-octane gasoline blending components to high-octane components for use in high-performance gasoline fuels. The reformer also has an important function as the producer of hydrogen to the refinery hydrotreaters. A process model based on a unit model structure, is used for estimation of the process condition using data reconciliation. Measurements are clas...

Partially Connected Operation

RPC latencies and other network-related delays can frustrate mobile users of a distributed file system. Disconnected operation helps, but fails to use networking opportunities to their full advantage. In this paper we describe partially connected operation, an extension of disconnected operation that resolves cache misses and preserves client cache consistency, but does not incur the write late...

Micro Power Generation from Micro Fuel Cell Combined with Micro Methanol Reformer

1.1 Background Thanks to the breakthroughs in microfabrication technologies, numerous concepts of microsystems including micro aerial vehicles, microbots, and nanosatellites have been proposed. Contrary to ordinary electronic devices, these microsystems perform mechanical work and require the extended operation. As their functions are getting complex and advanced, their energy consumption is al...
