Optimization of the constrained Algebraic Reconstruction Technique for the performance of a variety of visual tasks.

This work demonstrates the application of a method to optimize image reconstruction algorithms on the basis of the performance of specific visual tasks that are to be accomplished using the reconstructed images. The evaluation of task performance is numerically realized by a Monte Carlo simulation of the complete imaging chain, including the final inference based on the reconstructions. Fundame...

Experimentally designed optimized conditions for catalytic performance of nanostructured RuO2 in Biginelli reaction

Nanostructured RuO2 powders were synthesized via a hydrothermal method at 180 °C for 12 h using 1 and 2 M NaOH aqueous solutions. The structure of the obtained nanomaterials was investigated by powder X-ray diffraction (PXRD) technique. The morphology the obtained materials were studied by field emission scanning electron microscope (FESEM). The technique showed that with changing the reaction ...

Fast distance-driven projection and truncation management for iterative cone-beam CT reconstruction

The purpose of this study was to improve the speed of the Simultaneous Algebraic Reconstruction Technique (SART) for truncated cone-beam (CB) projections using a distance-driven forward projector. First, we optimized the innermost loop of the projector for a cone-beam scanner with a circular source trajectory and a flat-panel imager. We showed that the innermost loop of the distance-driven proj...

Optimizing Guessing Strategies for Algebraic Cryptanalysis with Applications to EPCBC

In this paper we demonstrate how to use Mixed Integer Linear Programming to optimize guessing strategies for algebraic cryptanalysis with applications to the block cipher EPCBC. Using our optimized guessing strategy we are able to attack 5 rounds of EPCBC96 and 8 rounds of EPCBC-48 faster than brute force using one and two known plaintexts resp. Finally, we are able to identify a class of weak ...
