Expander codes | IEEE Conference Publication | IEEE Xplore
We present a new class of asymptotically good, linear error-correcting codes based upon expander graphs. These codes have linear time sequential decoding algorithms, logarithmic time parallel decoding algorithms with a linear number of processors, and are simple to understand. We present both randomized and explicit constructions for …

Isothermal Compressed Air Energy Storage (i-CAES) System
Specifically, energy density can be increased by operating at higher pressure and using an open-accumulator configuration. Also, the trade-off between efficiency and power density can be improved by deploying porous media inserts to enhance heat transfer, and with the optimization of the compression/expansion profile and of the air compressor/expander …
