question:
Academic higher education in Estonia is divided into three levels: bachelor's, master's, and doctoral studies. In some specialties (basic medical studies, veterinary, pharmacy, dentistry, architect-engineer, and a classroom teacher programme) the bachelor's and master's levels are integrated into one unit. Estonian public universities have significantly more autonomy than applied higher education institutions. In addition to organising the academic life of the university, universities can create new curricula, establish admission terms and conditions, approve the budget, approve the development plan, elect the rector, and make restricted decisions in matters concerning assets. Estonia has a moderate number of public and private universities. The largest public universities are the University of Tartu, Tallinn University of Technology, Tallinn University, Estonian University of Life Sciences, Estonian Academy of Arts; the largest private university is Estonian Business School.
answer:
What are the three levels of higher learning in Estonia?


question:
The brushless wound-rotor synchronous doubly-fed (BWRSDF) machine is the only electric machine with a truly dual ported transformer circuit topology (i.e., both ports independently excited with no short-circuited port). The dual ported transformer circuit topology is known to be unstable and requires a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set. If a precision means were available to instantaneously control torque angle and slip for synchronous operation during motoring or generating while simultaneously providing brushless power to the rotor winding set, the active current of the BWRSDF machine would be independent of the reactive impedance of the transformer circuit and bursts of torque significantly higher than the maximum operating torque and far beyond the practical capability of any other type of electric machine would be realizable. Torque bursts greater than eight times operating torque have been calculated.
answer:
What is the only device with dual ported transformer circuit topology?


question:
Plato describes the priestesses of Delphi and Dodona as frenzied women, obsessed by "mania" (μανία, "frenzy"), a Greek word he connected with mantis (μάντις, "prophet"). Frenzied women like Sibyls from whose lips the god speaks are recorded in the Near East as Mari in the second millennium BC. Although Crete had contacts with Mari from 2000 BC, there is no evidence that the ecstatic prophetic art existed during the Minoan and Mycenean ages. It is more probable that this art was introduced later from Anatolia and regenerated an existing oracular cult that was local to Delphi and dormant in several areas of Greece.
answer:

Who describes Delphi and Dodona as frenzied women?
