This paper presents a very fast and low-power address bus encoder, whose critical path delay and area are only weakly dependent on the address bus width. Although the encoding algorithm of the proposed structure is the same as the INC-XOR encoding, its encoder and decoder architectures, called DX, are much faster. The DX architecture implements the INC-XOR encoding partially (partial DX archite...

This paper describes how Matching Pursuit can be employed in an MPEG-4 video encoder as a replacement for the DCT at boundary-blocks to improve coding efficiency, while retaining backward compatibility. The key aspect of Matching Pursuit is that the video signal can be represented with less coefficients than with an orthogonal transform, due to the over-complete set of basis functions. However,...

Lossless coding will become the latest extension of the MPEG-4 audio standard. The lossless audio codec of the Technical University of Berlin was chosen as reference model for MPEG-4 Audio Lossless Coding (ALS). The MPEG-4 ALS encoder is based on linear prediction, which enables high compression even with moderate complexity, while the corresponding decoder is straightforward. The paper describ...

I propose encoder and decoder architectures for entanglement-assisted (EA) quantum low-density parity-check (LDPC) codes suitable for all-optical implementation. I show that two basic gates needed for EA quantum error correction, namely, controlled-NOT (CNOT) and Hadamard gates can be implemented based on Mach-Zehnder interferometer. In addition, I show that EA quantum LDPC codes from balanced ...

Auto-encoder is a special kind of neural network based on reconstruction. De-noising auto-encoder (DAE) is an improved auto-encoder which is robust to the input by corrupting the original data first and then reconstructing the original input by minimizing the reconstruction error function. And contractive auto-encoder (CAE) is another kind of improved auto-encoder to learn robust feature by int...

Abstract In this paper, a FPGA implementation of linear time LDPC encoder is presented. This encoder implementation can handle large size of input message. Linear Time encoder hardware architecture reduces the Complexity and area of encoder than generator matrix based encoder techniques. This encoder is simulated on different platform which includes Matlab & High level languages for 1/2 rate & ...

Domination theory is an important branch of Graph Theory and has many applications in Engineering, Communication Networks and many others. Allan, R.B., and Laskar, R., [1,2], Cockayne, E.J.,and Hedetniemi, S.T., [3], Haynes, T.W., and Slater, J.S., [4], have studied various domination parameters of graphs. Graphs associated with certain arithmetic functions which are usually called arithmetic g...

BACKGROUND Audit is a means of quality control for medical practice by which the profession should regulate its activities with intention of improving overall patient care. Objective of this study was to report 1 year basic clinical audit of a general surgical ward and comparison of results with available data. METHODS All patients admitted and managed in Department of Surgery Unit-II, Liaqua...
