No. of bitstreams: 0 Previous issue date: 2020-01-01; Change Impact Analysis aims to identify parts of a system affected by the proposed change implementation. Although one may find in literature techniques to automate the impact identification process, it is still highly dependent on the experience with the analyzed software. Studies in this area do not f...

Content filtering is based on the user's preferences and interests. Current recommendation systems suffer from the problem of a lack of initial information about new users...
A 3D cone separator geometry for lithium-ion batteries has been optimized taking into account the increase of radius size of one side. Theoretical simulations have been carried out for evaluating the influence of radius size in the cone structure at different discharge rates (1 C and 60 C) in which it was also determined the produced ohmic heat. The value of the discharge capacity in the cone structure depends ...

This process is faced with difficulty of standardization and obtaining accurate results, where usually the collect, storage and computation of results are manually real...
Novel multifunctional porous films have been developed by the integration of magnetic CoFe2O4 (CFO) nanoparticles into poly(vinylidene fluoride)-Trifuoroethylene (P(VDF-TrFE)), taking advantage of the synergies of the magnetostrictive filler and the piezoelectric polymer. The porous films show a piezoelectric response with an effective d33 coefficient of -22 pC/N-1, a maximum magnetization of 12 emu.g-1 and a m...
