Abstract: A methods and apparatus for coding and decoding a MATRIX. The coding method includes: dividing a MATRIX into layers according to a preset quantity of layers, and grouping MATRIX elements into different layers; performing, according to a determined to-be-coded layer number and in an order of layers one by one, coding processing on MATRIX elements at each layer to be coded; for a layer having a layer number less than or equal to the to-be-coded layer number, writing residual data between an original MATRIX element value corresponding to the layer and a corresponding MATRIX element predicted value into a bit stream; for a layer having a layer number greater than the to-be-coded layer number, writing no coded data of the layer into the bit stream; and coding the to-be-coded layer number and writing the coded layer number of the coded layer into the bit stream.

Abstract: A metal oxide semiconductor carbon nanotube thin film transistor circuit includes a p-type carbon nanotube thin film transistor and a n-type carbon nanotube thin film transistor stacked with each other. The p-type carbon nanotube thin film transistor includes a first semiconductor carbon nanotube layer, a first drain electrode, a first source electrode, a functional dielectric layer, and a first gate electrode. The n-type carbon nanotube thin film transistor includes a second semiconductor carbon nanotube layer, a second drain electrode, a second source electrode, a first insulating layer, and a second gate electrode. The first drain electrode and the second drain electrode are electrically connected with each other. The first gate electrode and the second gate electrode are electrically connected with each other.

Abstract: In a method, formal descriptions of network address and identification schemes are received. Then validity and completeness of the formal descriptions are verified. The network address and identification schemes are scheduled into a final description after the validity and completeness of the formal descriptions are verified. The final description is resolved into an applicable network address. Then the applicable network address and identification scheme is applied to a test network and the test network runs. The running performance of the test network is measured. The measurements are analyzed and sent to evaluating performance and evolution ability of the network address and identification schemes.
