The purpose of this study was to evaluate the usability of the System View, Map View, and Line View that constitute the Metropolitan Manila Development Authority (MMDA) mobile traffic navigator. The usability and information visualization evaluations were collected from 100 young professionals living in Quezon City and Mandaluyong City. The results indicated that Line View had the highest usability index followed by Map View and System View. Finally, structural equation modeling was applied to derive the causal relationship between effectiveness, efficiency, and satisfaction dimensions. The results could be very beneficial for MMDA especially in terms of improvement on the content and design of the mobile traffic navigator.

Time-dependent density functional theory has been used to calculate the spin-polarized field emission from carbon nanotubes with and without Fe adsorbates (atoms and clusters). Using our previously-developed approach [1], the electronic wave function was propagated in real time. Complex absorbing potentials have been employed to avoid artificial reflections from the boundaries and to allow long time simulations. It was observed that various adsorbates cause the separation of density into spin-polarized regions. The calculations predict that carbon nanotubes with various adsorbates can be used as spin-polarized current sources. [4pt] [1] J. A. Driscoll and K. Varga, Phys. Rev. B 80, 245431 (2009).
