Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Subset Source Coding

IEEE Transactions on Information Theory, 2015
Emerging applications including semantic information processing impose priorities on the possible realizations of information sources, so that not all source sequences are important. This paper proposes an initial framework for optimal lossless compression of subsets of the output of a discrete memoryless source (DMS).

Source coding for dependent sources

2012 IEEE Information Theory Workshop, 2012
In this work, we address the capacity region of multi-source multi-terminal network communication problems, and study the change in capacity when one moves form independent to dependent source information. Specifically, we ask whether the trade off between capacity and source independence is of continuous nature.

Lossless source coding with polar codes

2010 IEEE International Symposium on Information Theory, 2010
In this paper lossless compression with polar codes is considered. A polar encoding algorithm is developed and a method to design the code and compute the average compression rate for finite lengths is given. It is shown that the scheme achieves the optimal compression rate asymptotically. Furthermore, the proposed scheme has a very good performance at

Proactive source coding

2011 IEEE International Symposium on Information Theory Proceedings, 2011
A coding problem, over a slotted system, is introduced where the sender has to transmit one out of several packets to the receiver, but learns the request only at the beginning of each slot with prior statistical information about which packet is needed at the receiver.

Lossy source coding

IEEE Transactions on Information Theory, 1998
Summary: Lossy coding of speech, high-quality audio, still images, and video is commonplace today. However, in 1948, few lossy compression systems were in service. Shannon introduced and developed the theory of source coding with a fidelity criterion, also called rate-distortion theory.

The source coding game

IEEE Transactions on Information Theory, 1971
The encoding of a source whose probability distribution varies arbitrarily from letter to letter is considered. The problem is formulated as a two-person statistical game. The exponential rate of growth with block length of the minimum number of codewords needed to achieve a specified fidelity with respect to a single-letter distortion measure is ...

Causal source codes

IEEE Transactions on Information Theory, 1982
For a stationary memoryless source, let \(R_c(D)\) be the optimum rate for encoding the source with causal (i.e., non-anticipatory) encoders with respect to a single letter fidelity criterion at the distortion level \(D\), which the authors show to be the same whether block, sliding-block, or finite-state causal encoders are used.
