This article tries to give some guidelines to optimize the 3G-2G and 3G-3G handovers, from the extracted experience of a real network in development. The purpose of the adjustment of the 3G-2G handover parameters is to offer the users with dual terminals a quality, equal or better than those ones with only 2G terminals, where in general, the 3G coverage is minor that the 2G one. On the other ha...

Overlap in markup occurs where some markup structures do not nest, such as where the structural division of the text into lists, sections, etc., differs from the syntactic division of the text into sentences and phrases. The Multiple Annotation solution to this problem (redundant encoding in multiple forms) has many advantages: it is based on XML, the modeling of alternative annotations is poss...

Let L be a non empty loop structure. We say that L is add-left-cancelable if and only if: (Def. 1) For all elements a, b, c of L such that a + b = a + c holds b = c. We say that L is add-right-cancelable if and only if: (Def. 2) For all elements a, b, c of L such that b + a = c + a holds b = c. We say that L is add-cancelable if and only if: (Def. 3) For all elements a, b, c of L holds if a + b...

A hallmark of optimal decision making is that cues are weighted by their reliability. Previous studies have reported evidence for reliability weighting in several human perceptual decision-making tasks in which sensory noise was the only possible source of errors. Here we use a target detection task to test whether optimality generalizes to situations where stimulus ambiguity is an additional s...

This study compares velar movements for nasal vowels and consonants; it investigates contextual nasalisation; and it provides new data on how nasalisation is affected by speech rate. Velar position is measured with an electromagnetic articulatograph (EMA) for two French speakers. Our results confirm that (i) nasal vowels are produced with a lower velum height than nasal consonants; (ii) the con...

Three recent papers [5, 11, 8] have considered in complementary ways the combinatorial consequences of assuming that three squares overlap in a string. In this paper we provide a unifying framework for these results: we show that in 12 of 14 subcases that arise the postulated occurrence of three neighbouring squares forces a breakdown into highly periodic behaviour, thus essentially trivial and...

There is a deep interrelationship of the General Theory of Relativity and weak interactions in the model of Expansive Nondecelerative Universe. This fact allows an independent determination of the mass of vector bosons Z and W, as well as the time of separation of electromagnetic and weak interactions. In the early stage of the Universe creation, i.e. in the lepton era an equilibrium of protons...
