The power supply unit consists of two low-dropout (LDO) voltage regulators designed to provide up to 1.5-A output current which receive the power through the ethernet connector using the Power over Ethernet (PoE) standard technology [38, 39].
The division between triple-A output and that from places of greater individuality and more impressive innovation is smaller than ever: less a chasm between continents, more a crack in a paving slab, allowing players to step easily between high-budget blockbusters made by hundreds and rightfully award-winning games from teams of tens.
The second problem can be formulated as follows: Input: The set of concept names N C, an ABox (mathcal {A}), a similarity relation Sim, a concept C, and an individual a. Output: A nonempty context Σ⊆N C −atom(C) and a natural number n≥1 such that (mathcal {A} models overline {C}^{(mathrm {text {Sim}}_{Sigma },n)}(a)).
Input: The set of concept names N C, an ABox (mathcal {A}), a similarity relation Sim, a concept C, and an individual a. Output: A nonempty context Σ⊆N C −atom(C) and a natural number n≥1 such that (mathcal {A} models underline {C}_{(mathrm {text {Sim}}_{Sigma },n)}(a)).
