2013 arXiv   pre-print
We show how to solve a generalised version of the Multi-sequence Linear Feedback Shift-Register (MLFSR) problem using minimisation of free modules over F[x].  ...  We show how two existing algorithms for minimising such modules run particularly fast on these instances. Furthermore, we show how one of them can be made even faster for our use.  ...  INTRODUCTION The Multi-sequence Linear Feedback Shift-Register (MLFSR) synthesis problem has many practical applications in fields such as coding theory, cryptography and systems theory, see e.g. the references  ...

Robust Multi-modal MR Image Synthesis [chapter]

Thomas Joyce, Agisilaos Chartsias, Sotirios A. Tsaftaris
2017 Lecture Notes in Computer Science  
We present a multi-input encoder-decoder neural network model able to perform MR image synthesis from any subset of its inputs, outperforming prior methods in both single and multi-input settings.  ...  We demonstrate that a spatial transformer module [7] can be included in our model to automatically correct misalignment in the input data.  ...  Acknowledgements This work was supported in part by the US National Institutes of Health (2R01HL091989-05) and UK EPSRC (EP/P022928/1).

Solving Shift Register Problems over Skew Polynomial Rings using Module Minimisation [article]

Wenhui Li, Johan S. R. Nielsen, Sven Puchinger, Vladimir Sidorenko
2015 arXiv   pre-print
For many algebraic codes the main part of decoding can be reduced to a shift register synthesis problem.  ...  In this paper we present an approach for solving generalised shift register problems over skew polynomial rings which occur in error and erasure decoding of ℓ-Interleaved Gabidulin codes.  ...  Similar to Interleaved RS codes, see [24] and its references, the core task of decoding can be reduced to what is known as a multi-sequence skew-feedback shift register synthesis problem [25] .  ...

2014 ACM Transactions on Reconfigurable Technology and Systems  
However, the standard synthesis flow does not leverage this flexibility in the vast majority of cases.  ...  DSP blocks in modern FPGAs can be used for a wide range of arithmetic functions, offering increased performance, while saving logic resources for other uses.  ...  Logical shift left, logical shift right and arithmetic shift right can all be achieved using the DSP48E1 slice. The above examples demonstrate the flexibility of the DSP48E1 primitive.  ...
