Measuring the Changing Cost of Cybercrime

In 2012 we presented the first systematic study of the costs of cybercrime. In this paper, we report what has changed in the seven years since. The period has seen major platform evolution, with the mobile phone replacing the PC and laptop as the consumer terminal of choice, with Android replacing Windows, and with many services moving to the...

Validation of a steady BEM-FEM coupled simulation with experiments on flexible small scale propellers

This paper presents numerical and experimental results for the validation of a coupled Boundary Element Method (BEM)-Finite Element Method (FEM) simulation for uniform flows. In the first part of the paper the numerical models and the BEM-FEM coupling are presented. A large part of the paper is dedicated to the validation procedure which has...

Strategies to evaluate the visibility along an indoor path in a point cloud representation

Many research works have been oriented to the formulation of different algorithms for estimating the paths in indoor environments from three-dimensional representations of space. The architectural configuration, the actions that take place within it, and the location of some objects in the space influence the paths along which is it possible...

Challenges in flying quadrotor unmanned aerial vehicle for 3D indoor reconstruction

Three-dimensional modelling plays a vital role in indoor 3D tracking, navigation, guidance and emergency evacuation. Reconstruction of indoor 3D models is still problematic, in part, because indoor spaces provide challenges less-documented than their outdoor counterparts. Challenges include obstacles curtailing image and point cloud capture,...
