Electronic voting systems are created to facilitate the election, accelerate voting and counting votes and increase turnout for the election. The main problems of the electronic systems are related with the assurance of system security (cryptographic security and protection against frauds) and a guarantee that the voters are anonymous. The authorization of voters and the anonymity of them seem ...

Random forests are one of the most successful ensemble methods which exhibits performance on the level of boosting and support vector machines. The method is fast, robust to noise, does not overfit and offers possibilities for explanation and visualization of its output. We investigate some possibilities to increase strength or decrease correlation of individual trees in the forest. Using sever...

Cardiac catheter ablation is a minimally invasive medical procedure to treat patients with heart rhythm disorders. It is useful to know the positions of the catheters and electrodes during the intervention, e.g. for the automatization of cardiac mapping. Our goal is therefore to develop a robust image analysis method that can detect the catheters in X-ray fluoroscopy images. Our method uses ste...

The evaluation of flexible manufacturing system(FMS) is regarded as a multiple attribute group decisionmaking problem and has a critical impact on the improvement of manufacturing system competitiveness. Therefore, an effective group decision-making model using fuzzy-TOPSIS method is developed for the evaluation of alternative FMSs where the information available is subjective and imprecise. In...

This article describes the process of the Canadian Cardiovascular Society 2010 atrial fibrillation (AF) guidelines update. Guideline development was based on the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system of evaluation. GRADE separates the quality of evidence (very low, low, moderate, or high quality) from the strength of recommendations (strong or conditio...

To reliably determine the camera pose of an image relative to a 3D point cloud of a scene, correspondences between 2D features and 3D points are needed. Recent work has demonstrated that directly matching the features against the points outperforms methods that take an intermediate image retrieval step in terms of the number of images that can be localized successfully. Yet, direct matching is ...

Obtaining user feedback (using votes) is essential in ranking user-generated online content. However, any online voting system is susceptible to the Sybil attack where adversaries can out-vote real users by creating several Sybil identities. In this paper, we present SumUp, a Sybilresilient online content rating system that leverages trust networks among users to defend against Sybil attacks wi...
