background and aims. a plethora of definitions has been used for periodontitis for epidemiological studies. the aim of this cross-sectional study was to assess the impact of different case definitions on the prevalence of periodontitis and to find the level of agreement among them. materials and methods. periodontal records of 300 subjects were randomly selected from the database of oral health ...

In this paper we propose a simple but powerful method for normalizing various sources of mismatch between training and testing conditions in speech recognizers, based on a recent training methodology called the Generalized Probabilistic Descent method (GPD). In this new framework, a gradient based method is used to adapt parameters of the feature extraction process in order to minimize distorti...

We present a theory of normalization for multimedia databases. We introduce new types of functional dependencies between different types of media data. Thus, the definition of functional dependency is based upon a specific technology used to detect semantic relationships between complex data types, which need to be compared through approximate match paradigms . Index terms __ Multimedia Databas...

The relationship between homelessness and contemporary forms of slavery human trafficking is well established. Early research often took this for granted was frequently divorced from housing policy or theory. Interdisciplinary has continued to ignore how the sector struggled with its own issues around defining what dominant definition (the United States’ HUD-Rossi definition) meant our understa...

Definition For a given query, a personalized Web search can provide different search results for different users or organize search results differently for each user, based upon their interests, preferences, and information needs. Personalized web search differs from generic web search, which returns identical research results to all users for identical queries, regardless of varied user intere...

In the last years, knowledge technologies have been exploited for self-regulation functionalities inside elearning systems. The definition of integrated system suitably scaffolding learners to improve their experience is still lacking though. In this work, we propose an innovative Web-based educational environment that sustains metacognitive self-regulated learning processes upon Semantic Web a...

The carbohydrate compositional analysis by HPLC confirmed that IMO is a mixture of shortchains carbohydrates consists of glucose units in 2-7 or more. Therefore, it is defined as a short-chained fiber molecule (resistant oligosaccharide) (AACC Definition, 2000). The routine analysis of fiber content in IMO is being performed using HPLC-RI system and is based upon the published scientific papers;

This paper presents an approach towards the definition of a formal framework for rhetorical argumentation. Before describing the competence theory behind the framework, we introduce the notion of rhetorical argument, and describe the New Rhetoric, a well known theory in the philosophy of argumentation, upon which our work is based.

The purpose of this paper is to present a necessary and sufficient condition for irreducibility of nonlinear input–output delta differential equations. The condition is presented in terms of the common left divisor of two differential polynomials describing the behaviour of the system defined on a homogenous time scale. The concept of reduction is explained. Subsequently, the definition of tran...
