patients with valvular heart disease and suffering atrial fibrillation of more than 12 months duration have a low probability of remaining in sinus rhythm after valve surgery alone. we performed intra-operative radiofrequency ablation or cryoablation as an alternative to surgical maze ііі procedure to create linear lesion lines for conversion of this arrhythmia to sinus rhythm. a total of 30 pa...

Three experiments investigated the role of word stress and vowel harmony in speech segmentation. Finnish has fixed word stress on the initial syllable, and vowels from a front or back harmony set cannot co-occur within a word. In Experiment 1, we replicated the results of Suomi, McQueen, and Cutler (1997) showing that Finns use a mismatch in vowel harmony as a word boundary cue when the target-...

This paper is a seminar paper that summarizes Fran­ cis Edward Su’s paper “Rental harmony: Sperner’s lemma in fair division” [1] in 1999. In this paper we introduce and prove Sperner’s Lemma. Then, we introduce the fair division problem and an al­ gorithm based on Sperner’s lemma that can solve some variants of the fair division problem.

According to the great importance of safety in aerospace industries, identification of dynamic parameters of related equipment by experimental tests in operating conditions has been in focus. Due to the existence of noise sources in these conditions the probability of fault occurrence may increases. This study investigates the effects of noise in the process of modal parameters identification b...

In this paper a bimodal discrete urban road network design problem with bus and car modes is investigated. The problem consists of decision making for lane addition to the existing streets, new street constructions, converting some two-way streets to one-way streets, lane allocation for two-way streets, and the allocation of some street lanes for exclusive bus lanes. Two objectives are consider...
