This chapter addresses Voronoi cell-based algorithms, solving the Shortest Vector Problem, a fundamental challenge in lattice-based cryptanalysis. Several optimizations reduce the original algorithm's execution time. The algorithm suitability for parallel&#x...
This special section on Recent Advances in Graphics and In- teraction features the papers submitted to Computers & Graphics (C&G) and presented at the 2021 edition of the International Conference on Graphics and Inte...
This article proposes a Markov Chain Monte Carlo (MCMC) rendering algorithm based on a family of guided transition kernels. The kernels exploit properties of ensembles of light transport paths, which are distributed according to the ...
Traditional post-hoc high-fidelity scientific visualization (HSV) of numerical simulations requires multiple I/O check-pointing to inspect the simulation progress. The costs of these I/O operations are high and can grow exponentially with inc...
The amount of information preserved in Portuguese archives has increased over the years. These documents represent a national heritage of high importance, as they portray the country’s history. Currently, most Portuguese archives have made&#x...
