In home health care (HHC) services, nurses or professional caregivers are dispatched to patients’ homes to provide medical care services, such that each patient can stay at home to be treated periodically. The HHC problem consists of the nurse rostering problem (NRP) and the vehicle routing problem with time windows (VRPTW), both of which are NP-hard problems, which are harder or equal to the h...

People with vertigo have the illusion that the environment is moving about them, or that they are moving with respect to the environment.(DTB 2009) The condition usually originates in the peripheral nervous system, for example, due to a disorder of the inner ear such as Ménière's disease, benign paroxysmal positional vertigo (BPPV), or labyrinthitis and vestibular neuritis. It can also be due t...

Using a combination of aspirin, anti-tuberculosis drugs and steroids may help to reduce the number of strokes and deaths in patients with tuberculous meningitis.

Complementation and determinization are two fundamental notions in automata theory. The close relationship between the two has been well observed in the literature. In the case of nondeterministic finite automata on finite words (NFA), complementation and determinization have the same state complexity, namely Θ(2n) where n is the state size. The same similarity between determinization and compl...

When incorrectly designed, windows can be responsible for unnecessary energy consumption in a building. This may result from its dimensions, orientation and shadowing. In a moderate climate like the Portuguese, and considering an annual thermal comfort assessment of a space, if windows are under-dimensioned or overshadowed, they can contribute to the increase of heating needs. However, when ove...

The performance of a Video-on-Demand broadcasting scheme is commonly evaluated by the maximum waiting time encountered by the customer before viewing can start. This paper addresses the issue of minimizing the average waiting time. Recently, we proposed Harmonic Block Windows scheduling to specifically minimize the average waiting time for given bandwidth. Here, we present an efficient heuristi...
