Chinese designers especially emphasize on "green design" to create national ideal green home,but the real "green building" not only refers to the low-pollution and low energy consumption of construction,but also to whether the building has stable and sound energy aggregation effect and whether it is conducive to people s physical and mental health should be the basic standards of "green".

In order to distinguish own faults of nonlinear elements from their look-like faults, the paper analyses oriented energy ellipsoids of voltagechange matrices on limited accessible nodes.

The oriented energy of filter response is introduced for detecting orientation strength of vessels in that direction.

This paper analyzes the characteristics of IPv6 routing structure in detail,introduces various techniques IPv6 routing lookup,proposes a fast algorithm based on aggregated bit vector for routing lookup and compares the performances of the algorithm with common binary search algorithms.

An shifted undecimated wavelet packet transform(SUWPT) excision algorithm is proposed for narrowband interference in DSSS communication system,which focuses the interference on one sub-band by frequency shifted,finds and removes it by energy compaction measure(EMC).
