We study algorithmic and structural aspects of connectivity in hypergraphs. Given a hypergraph H = (V, E) with n= |V |, m= |E| and p = ∑ e∈E |e| the fastest known algorithm to compute a global minimum cut in H runs in O(np) time for the uncapacitated case, and in O(np+ n2 log n) time for the capacitated case. We show the following new results. • Given an uncapacitated hypergraph H and an intege...

In order to identify the effects of different levels of nitrogen fertilizer on seed yield and seed growth indices of some bread and durum wheat genotypes, a field experiment was conducted in 2013-2014 in Khuzestan Agricultural and Natural Resource Research Center. The experiment was designed as a split plot with three replications. Nitrogen application rates (50, 100 and 150 kg N.ha-1) were ass...

The present study addresses comparison of two analysis methods of voice production, inverse filtering and videokymography (VKG). Speech data were collected from two male speakers using sustained phonation during laryngoscopy (sound corresponding approximately to the vowel /ä/). The type of phonation was varied between breathy, normal, and pressed. From the waveforms given by inverse filtering, ...

Neurological degenerative diseases are becoming a growing concern in modern society. The successful treatment of these diseases depend greatly in early detection. Speech has been routinely used by specialists as a valuable correlate in the assessment of pathological disease. Specifically voicing can serve as a very introspective correlate for this practice. The present paper uses a methodology ...

this paper reviews the relationship between inflation rate and minimum wage in iran’s economy over the 1969-2005. according to the economic literature, there is a narrow relationship between inflation rate and minimum wage. some economists believe in increased inflation due to minimum wage. the other group of economists considers the increased inflation as a cause for increasing minimum wage. t...
