In the context of the NEOLOGOS speech database creation project, we have studied several methods for the selection of representative speaker recordings. These methods operate a selection by optimizing a quality criterion defined in various speaker similarity modeling frameworks. The obtained selections can be cross-validated in the modeling frameworks which were not used for the optimization. T...

In this paper we describe the range of values that can be taken by the fractional weak discrepancy of a poset and characterize semiorders in terms of these values. In [6], we defined the fractional weak discrepancy wdF (P ) of a poset P = (V,≺) to be the minimum nonnegative k for which there exists a function f : V → R satisfying (1) if a ≺ b then f(a) + 1 ≤ f(b) and (2) if a ‖ b then |f(a) − f...

The fractional weak discrepancy of a poset P , written wdF (P ), is the least k such that some f : P → R satisfies f(y)− f(x) ≥ 1 for x ≺ y and |f(y)− f(x)| ≤ k for x‖y. We determine the minimal forbidden subposets for the property wdF (P ) ≤ k when k is an integer.

happiness is among the concepts which were subject of empirical studies in 1960s. this concept has been used interchangeably with such concepts as joy, satisfaction with life and the like. while meaningfully correlating with the feeling of joy and satisfaction with life, as indicated by numerous researches, the feeling of happiness is affected by different factors and situations. the present re...

social happiness is one of the humanity’s most necessary innate needs and which plays a crucial role in the sublimity of individuals and society. reaching this would occur once individual has either physical or mental health. one of the effective factors in increasing the amount of individuals’ social happiness especially in women is providing them with mental dimension of security e.g. felling...

conclusions the results showed that heart failure had a negative impact on the quality of life for patients. therefore, evaluation and improvement of quality of life for these patients should be considered one of the duties of nurses. background currently, examining the quality of life is considered an important aspect of the study of chronic diseases. heart failure affects the quality of life ...

objectives: quality of life, when referring to an individual’s health, is called health-related quality of life. the purpose of this study is to assess self-perceived hearing loss related quality of life of adolescents with hearing loss and its relationship with sex, age sub-groups or school settings with domains of quality of life. methods: a school based survey was conducted in tehran city. u...

We analyze optimal consumption and portfolio choice when the agent takes the market as given, with applications to pension insurance. First, we recall the results for the conventional additive and separable expected utility model. We explain why this model is not viable in a temporal context. As a consequence, when confronted with real data this theory meets with several conflicting implication...

In response to the facts that some Asian developing countries were experiencing the fastest rate of industrialisation and urbanisation, several international initiatives called for a better and ‘sustainable’ urban management. Development of management tools including strategic environmental assessment (SEA), life cycle assessment (LCA), cost benefit analysis (CBA), and environmental managemen...
