[T ] is just a typical closed set in the topology on ω1 whose basic neighborhoods are the sets of the form Np = {f : ω1 → ω | p ⊆ f}, where p : α → ω for some countable α. Associated to T is a closed game G(T ) on ω of length ω1: at round α in G(T ), player I plays mα, then player II plays nα. Letting f(α) = 〈mα, nα〉 for all α < ω1, we say that player II wins the run of G(T ) determined by f if...

It makes the topology of distribution network more complex to contain a lot of distribution generations (DGs) in it. For this reason, a fault location approach suitable to the distribution network containing DGs is proposed. Firstly, according to the results of power flow calculation, a database of voltage sag is established; then the power quality information is acquired by power quality monit...

As the conception of and debates on regional powers have been led by political science, this paper aims to contribute to the discussion from an economics perspective. Based on the discussion of different concepts of economic power—such as those of Schumpeter, Perroux, Predöhl, or Kindleberger—concepts of technological leadership, and the global value chain approaches, the paper develops a resea...
