The use of ontologies can contribute significantly to the organization of concepts, structure and relations within a knowledge domain. Incorporation of ontologies in tools for information access provides foundation for enhanced, knowledge-based approaches to surveying, indexing and querying of document collections. We introduce in this paper the notion of an instantiated ontology as a subontolo...

The Session Description Protocol (SDP) was intended to describe multimedia sessions for the purposes of session announcement, session invitation, and other forms of multimedia session initiation. SDP was not intended to provide capability indication or capability negotiation; however, over the years, SDP has seen widespread adoption and as a result it has been gradually extended to provide limi...

A digital option is a special type of financial derivative with a non-linear discontinuous payoff function. In spite of this, the payoff is simple enough to allow (relatively) easy valuation of these contracts. It is the reason why digital options can be (and regularly are) applied to decompose and hedge statically the positions in many options with more complicated and usually discontinuous pa...

External root resorption in posttreatment orthodontic patients, if severe, may jeopardize the retention of the tooth or teeth involved. Numerous studies (1-5) have been undertaken to determine the relationship between the frequency and severity of external root resorption and orthodontic movement. Some investigators found the incidence of root resorption to be low (6-9), while others found it t...

AIM Tooth eruption is defined as the movement of a tooth from its site of development within the alveolar process to its functional position in the oral cavity [Massler et al., 1941]. The process of tooth eruption can be divided into different phases: pre-eruptive bone stage, alveolar bone stage, mucosal stage, preocclusal stage, occlusal stage and maturation stage [Andreasen et al., 1997]. Any...

This study examines in detail - i) the magnitude, nature and severity of thought disorder in schizophrenia, ii) the correlations between type and severity of thought disorder with socio-demographic and clinical variables, and iii) differences between different subtypes of schizophrenia. Forty five schizophrenics (Research Diagnostic Criteria) were assessed by 'live' interview as well as tape re...

BACKGROUND Traumatic dental injury (TDI) is an important public dental health problem among schoolchildren. The aim of the study was to investigate the relationship between TDIs, obesity, and other possible associated factors like gender, overjet, lip coverage, parents' education level and family income among 12-year old Jordanian schoolchildren. METHODS A cross-sectional population-based stu...

Although poor response to neuroleptics has traditionally been considered a characteristic feature of negative schizophrenic symptoms (Crow 1980; Andreasen et aJ 1982), several recent studies have documented significant improvement in negative symptoms in schizophrenic patients treated with neuroleptics (Breier et al 1987; vanKammen et al 1987; Kay and Singh 1989; Tendon et al 1990; Meltzer, 199...

This paper presents a method to develop Ultra-High Performance Fibre Reinforced Concrete (UHPFRC). Towards an efficient utilization of binders and fibres in UHPFRC, the modified Andreasen & Andersen particle packing model and the hybridization design of fibres are utilized. Particularly, the UHPFRC with ternary fibres is appropriately designed and tested. The flowability, mechanical properties ...
