This study investigates the possibility to recover the voice strength, i.e. the sound level produced by the speaker, from the signal recorded. The dataset consists of a set of isolated vowels (720 tokens) recorded in a situation where two interlocutors interacted orally at a distance comprised between 0.40 and 6 meters, in a furnished room. For each token, voice strength is measured at the inte...

In the last few lectures we have seen how to obtain high confidence bounds on the generalization error of functions learned from function classes of limited capacity, measured in terms of the growth function and VC-dimension for binary-valued function classes in the case of binary classification, and in terms of the covering numbers, pseudo-dimension, and fat-shattering dimension for real-value...

The aim of this study was to evaluate the fracture strength of teeth with different cavosurface margin cavity preparations and restored with composite resin and different adhesive systems. Eighty premolars were randomly divided in 8 groups, as follow: G1- sound teeth; G2- MOD preparation (no restoration); G3- Adper Single Bond without bevel preparation (butt joint); G4- Adper Single Bond with b...

PURPOSE The objective of this study was to evaluate fracture strength of collarless metal-ceramic FPDs according to their metal coping designs. MATERIALS AND METHODS Four different facial margin design groups were investigated. Group A was a coping with a thin facial metal collar, group B was a collarless coping with its facial metal to the shoulder, group C was a collarless coping with its f...

In engineering application, the hot press assembly technology is often used to improve stability of rotor structure, but conventional design methods cannot effectively evaluate influence this process on strength, which easily causes strength exceed its safety margin range, and seriously it will lead failure structure. This paper takes cylindrical magnet surface-mounted high-speed permanent sync...

This paper examines the determinants of emerging market banks’ derivative usage and impact on bank value, total risk stability. Our empirical evidence first suggests that is driven primarily by net interest margin, concentration institutional strength. In addition, although appears to reduce it does not affect risk. Moreover, banks can instability using derivatives. findings have important impl...

the study examines production efficiency of farmers under national fadama-ii project in oyo state nigeria. primary data were collected from two hundred and sixty-four farmers using multistage sampling technique. the analytical framework used for the study include: descriptive, infrastructure index, gross margin and stochastic frontier production function. average infrastructural index in the ar...

abstract the main aim of the paper is to determine the marketing efficiency of poultry industry in karaj. in this research the marketing margin and the marketing efficiency of poultry market in different level of the market in karaj was calculated. the results showed that slaughter houses gain the main part of marketing margin and marking profit. the share of slaughter house was more that 50 pe...

Financial statements are a means to determine the company’s financial performance in order obtain valuable results. The aim is analyze development of PT. Astra Otoparts Tbk from year year, based on 2019 and 2021 balance sheets income using usual size analysis technique. Researchers used descriptive research methods with quantitative approach for methods. Based survey results, 2020 there will be...

Current statistical models for structured prediction make simplifying assumptions about the underlying output graph structure, such as assuming a low-order Markov chain, because exact inference becomes intractable as the tree-width of the underlying graph increases. Approximate inference algorithms, on the other hand, force one to trade off representational power with computational efficiency. ...
