A Content-Driven Architecture for Medical Image Segmentation

Autor: Stefan Thumfart, Bertram Sabrowsky-Hirsch, Wolfgang Fenz, Richard Hofer

Publikováno v: Proceedings of the 6th International Conference on Communication and Information Processing.

As the U-Net architecture continues to push the state of the art in medical image segmentation, and keeping track of the multitude of derived models becomes increasingly difficult, opposing trends have emerged that prefer a coherent framework of anci

On the 2-Adic Complexity of the Two-Prime Generator

Autor: Richard Hofer, Arne Winterhof

Publikováno v: IEEE Transactions on Information Theory. 64:5957-5960

Hu introduced a simple method to compute the 2-adic complexity of any periodic binary sequence with ideal two-level autocorrelation. We extend this approach to some other sequences. First, we provide a substantially shorter proof of the maximality of

On the arithmetic autocorrelation of the Legendre sequence

Autor: Richard Hofer, Arne Winterhof

Publikováno v: Advances in Mathematics of Communications. 11:237-244

The Legendre sequence possesses several desirable features of pseudorandomness in view of different applications such as a high linear complexity (profile) for cryptography and a small (aperiodic) autocorrelation for radar, gps, or sonar. Here we pro

Measures of Pseudorandomness: Arithmetic Autocorrelation and Correlation Measure

Autor: László Mérai, Richard Hofer, Arne Winterhof

Publikováno v: Number Theory – Diophantine Problems, Uniform Distribution and Applications ISBN: 9783319553566

We prove a relation between two measures of pseudorandomness, the arithmetic autocorrelation, and the correlation measure of order k. Roughly speaking, we show that any binary sequence with small correlation measure of order k up to a sufficiently la

Linear Complexity and Expansion Complexity of Some Number Theoretic Sequences

Autor: Richard Hofer, Arne Winterhof

Publikováno v: Arithmetic of Finite Fields ISBN: 9783319552262
WAIFI

We study the predictability of some number theoretic sequences over finite fields and thus their suitability in cryptography. First we analyze the non-periodic binary sequence \(\mathcal {T}=(t_n)_{n\ge 0}\) with \(t_n=1\) whenever n is the sum of th

High-Specific Impulse Operation of the BPT-4000 Hall Thruster for NASA Science Missions

Autor: Richard Hofer

Publikováno v: 46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit.

To meet the propulsive requirements, cost constraints, and scientific objectives of NASA deep-space missions, high-performance, low-cost electric propulsion (EP) options are needed. Commercial EP technology has matured sufficiently that ion and Hall
