The Hot Electrons in and Above the Auroral Ionosphere: Observations and Physical Implicationsuch as auroral arcs and the more irregular and variable structures that occur during auroral breakup. In view of its overriding importance, the present discussion will concentrate on this issue, even though other important areas such as the electrons that produce pulsating aurora will remain untouch

High Latitude Electromagnetic Plasma Wave Emissionsthe whistler mode. The first satellite investigation of auroral hiss was reported by Gurnett (1966) who showed that auroral hiss is closely correlated with intense fluxes of precipitating auroral electrons. This relationship was subsequently confirmed and refined by a number of low-altitude satellit

Kerstin Fredgaads to a better performance. We obtain similar separation for list update algorithms. Lastly, we show that, surprisingly, certain randomized algorithms which are superior to MTF in the classical model are not so in the parameterized case, which matches experimental results.

R. A. Wolf,R. W. Spiro can be .(1 + .)-approximated..We demonstrate the applicability of our approach on two classes of integer programs, namely, totally unimodular integer programs and integer programs with two variables per inequality. Further, for combinatorial optimization problems our method yields polynomial time a

Asgeir Brekkeonic number), we show that for every .> 0 there is a polynomial time .-approximation algorithm for our problem. Our analysis of the greedy algorithm shows that when applied to covering a bipartite graph using copies of . . bicliques, it returns a feasible solution whose cost is at most . where . den

Richard Vondrakow a lower bound of 1.20 on the competitive ratio of any deterministic algorithm..We extend our techniques and analyze the competitive ratio of greedy with respect to the ℓ. norm. We show that the greedy algorithm performs within at most 2-Ω(1/.) of the optimum. We also show a lower bound of 2 − .(l
