  • While various aspects of syntactic structure have been shown to bear on the determination of phraselevel prosody, the text-to-speech field has lacked a robust working system to test the possible relations between syntax and prosody. We describe an implemented system which uses the deterministic parser Fidditch to create the input for a set of prosody rules.

  • In statistical machine translation, a researcher seeks to determine whether some innovation (e.g., a new feature, model, or inference algorithm) improves translation quality in comparison to a baseline system. To answer this question, he runs an experiment to evaluate the behavior of the two systems on held-out data. In this paper, we consider how to make such experiments more statistically reliable.

  • In this paper we investigate how to automatically determine if two document collections are written from different perspectives. By perspectives we mean a point of view, for example, from the perspective of Democrats or Republicans. We propose a test of different perspectives based on distribution divergence between the statistical models of two collections. Experimental results show that the test can successfully distinguish document collections of different perspectives from other types of collections. ...

  • This paper addresses the issue of POS tagger evaluation. Such evaluation is usually performed by comparing the tagger output with a reference test corpus, which is assumed to be error-free. Currently used corpora contain noise which causes the obtained performance to be a distortion of the real value. We analyze to what extent this distortion may invalidate the comparison between taggers or the measure of the improvement given by a new system. The main conclusion is that a more rigorous testing experimentation setting/designing is needed to reliably evaluate and compare tagger accuracies.

  • One of the more promising processes for the energetic transformation of waste is the anaerobic digestion of the Organic Fraction of Municipal Solid Waste. An experimental campaign was carried out on three different samples of OFMSW from Waste Separation, one as received and two obtained after mechanical treatment: OFMSW slurry (liquid fraction) and OFMSW Waste. Anaerobic Biogasification Potential and anaerobic digestion tests were carried out, investigating the effects of inoculum and pH. The OFMSW Waste was also examined to evaluate the possibility to dispose of it in a landfill.

  • Originally, it was planned that there would be equal numbers of males and females and an equal number of students from the four faculties with the highest percentage of NESB students. However, as noted above, the opportunity to sit a free IELTS Test proved to be much more attractive to some students from some faculties than to others. There was no interest from students enrolled in the Faculty of Design, Architecture and Building, and a great deal of interest from students enrolled in the Faculty of Nursing, Midwifery and Health.

  • This study uses what Cresswell (2003) refers to as a ‘mixed methods approach’, one that combines quantitative and qualitative data collection and a ‘sequential explanatory strategy’ in which the collection and analysis of the quantitative data is followed by the collection and analysis of the qualitative data (p 215).

  • CO2 injection has recently been shown to provide significant enhanced oil recovery from naturally fractured reservoirs1. Li et al. (2000) performed CO2 injection at 1750 psig on artificially-fractured cores after water flooding in a dead-oil system. Gravity drainage was suggested to be the dominant recovery mechanism in these tests, with significant tertiary oil recovery after water flooding. The authors observed that the recovery of initial oil at the start of the CO2 injection declined as the rock permeability decreased and the initial water saturation increased....

  • We utilize a longitudinal survey of registrants for the Graduate Management Admissions Test (GMAT) to estimate the economic returns to an MBA. The GMAT exam, an admissions requirement for most MBA programs, is similar to the SAT for undergraduates without the competition from the ACT. The survey, sponsored by the Graduate Management Admissions Council (GMAC), was administered in four waves, beginning in 1990 and ending in 1998. 14 In addition, survey responses were linked to GMAC’s registration and test data, which includes personal background information and GMAT scores.

  • In morocco access to antenatal services is limited and many HIV- positive pregnant women are not identified for lack of HIV testing, especially in rural areas. The fear of stigma and discrimination is a major barrier for women to get tested, both at home and in health care settings. Breast-feeding is contraindicated by the Ministry of Health (an outdated recommendation), but formula is provided in only three cities and only 56 percent of the rural population has access to safe drinking water.

  • Hand eczema is one of the most common clinical conditions treated and evaluated both among general dermatologists and in dermatological departments. Hand eczema is the most common occupational skin disease and one of the most frequent occupational disorders overall. Hand eczema can be long lasting and incapacitating. Research within the last decades has expanded our knowledge significantly. This knowledge has yet to find its way into general dermatological textbooks. D.S.Wilkinson provides a thorough introductory chapter on the definitions and problems of classification.
