We study on-line version of size-Ramsey numbers of graphs defined via a game played between Builder and Painter: in one round Builder joins two vertices by an edge and Painter paints it red or blue. The goal of Builder is to force Painter to create a monochromatic copy of a fixed graph H in as few rounds as possible. The minimum number of rounds (assuming both players play perfectly) is the on-...

Let X1; X2; ::: be independent, identically distributed, zero mean random variables with ( )-regularly varying tails, > 1. For Sn = Pn i=1Xi, it is known that under these distributional assumptions, P(Sn > x) nP(X1 > x) as x ! 1, uniformly for x cn for any constant c > 0. Here, we show that the process Mn = maxfSi i : i ng, for any constant 0, behaves in a similar manner. This allows us to gene...

The endgame of Lines of Action (LOA) is problematic because (1) LOA evaluation functions are not good predictors in the case of forced wins and (2) the state-space complexity of the LOA endgame is too large to use endgame databases. Because of the frequency of forced moves and the mobility component in the LOA endgame the utility of proof-number (PN) search is investigated in this paper. Also t...

We consider the set S(n, 0) of monic complex polynomials of degree n ≥ 2 having all their zeros in the closed unit disk and vanishing at 0. For p ∈ S(n, 0) we let |p|0 denote the distance from the origin to the zero set of p. We determine all 0-maximal polynomials of degree n, that is, all polynomials p ∈ S(n, 0) such that |p|0 ≥ |q|0 for any q ∈ S(n, 0). Using a second order variational method...

صخلملا Seasonal variation of zooplankton biomass has been carried out at two selected sites on Greater Zab River. Monthly samples of water were collected during period from January to December 2008. Some physico-chemical properties of water were studied including water temperature (from 8 to 30.5 C), hydrogen ion concentration (from 6.3 to 8), EC (from 255 to 821 μs.cm), turbidity (1085 NTU), d...

Semiconductor nanowires (NWs) are very promising building blocks for future electronic and optoelectronic devices. Realizing this, nevertheless, requires overcoming several important challenges, such as control and evaluation of doping levels in NWs. Due to the nanoscale nature of NWs, characterization techniques, such as Hall effect measurements and four-point probes, used conventionally for t...
