We show that the nonemptiness problem for two-way automata with only one endmarker over unary alphabets is complete for nondeterministic logarithmic space. This should be contrasted with the corresponding problem for two-way Air Max Thea Womens
automata with two endmarkers, which Air Max Thea Toronto is known to be NP-complete.
A method is described for calculating the mean cover time for a particle performing a simple random walk on the vertices of a finite connected graph. The method also yields the variance and generating function of the cover time. A computer program is available which utilises the approach to provide results for vertex symmetric graphs. Some examples are given.
It is unclear why productivity growth in the information and communication technology (ICT) industry differs considerably among countries. This paper shows that, for Sweden, it is primarily the use of the double deflation method that has created the apparent ICT-miracle.
Using molten alloys, the electrolysis of soda lime glass has been studied. Ions from a Nike Air Max Womens 2013
molten anode can be driven into soda lime glass by applying a modest electric potential. The anode current densities have been measured. The temperature and potential dependences have also been measured. The current-time behavior depends on the ion exchange. In a molten alloy the most easily oxidized metal is suited for exchange.
