The cyclic variation in the energy envelope of the speech signal results from the production of speech in syllables. This acoustic property is often identified as a source of information in the perception of syllable attributes, though spectral variation can also provide this information reliably. In the present study of the relative contributions of the energy and spectral envelopes in speech ...

We propose a method, called PREDIQT, for model based prediction of impact of architecture design changes on system quality. PREDIQT supports simultaneous analysis of several quality attributes and their trade-offs. This paper argues for the feasibility of the PREDIQT method based on a comprehensive industrial case study targeting a system for managing validation of electronic certificates and s...

Wheat is affected by various biotic and abiotic stresses, especially salinity, which reduces the growth yield drastically. With this view, an experiment was conducted to observe genotypic differences in agro-morphological, yield, biochemical responses salinity. Experimental variables consisted of five salt-tolerant genotypes (G 13, G 20-1, 9, 22, 20-2), one susceptible genotype 24) standard che...

In this paper we propose a methodology to measure the characteristics and composition of intermediate products using productivity indicators based on directional distance functions. We evaluate how quality attributes interact with the quantity level in grapes production, and find evidence of a trade-off between quantity and aggregate quality for Chardonnay. ∗Dipartimento di Scienze Economiche —...

The view that children understand the mind via a coherent theory is supported by evidence that children rigidly follow a Seeing = Knowing Rule: seeing, and only seeing, leads to knowing. This paper presents two kinds of evidence that children do not follow this rule. First, we critically review previous findings that children neglect the role of inference and argue that these studies do not in ...

The pattern is, in short, at the same time a thing, which happens in the world, and the rule which tells us how to create that thing, and when we must create it. It is both a process and a thing; both a description of a thing which is alive, and a description of the process which will generate that thing

When designing a software system it is beneficial to study and use architectural styles from literature, to ensure certain quality attributes. However, as the interpretation of literature may differ depending on the background and area of expertise of the person reading the literature, we suggest that structured discussions about different architecture candidates provides more valuable insight ...

A model is developed that can estimate recreational welfare measures for access to and changes in quality attributes at long distance single-visited tourist sites with only on-site information available. By defining the good (a visit to the site) as indivisible in consumption welfare measures are derived by simply capturing or estimating the chokeprice(s). Stated and revealed methods suitable t...
