QoS adaptation in inter-domain services

Abstract

QoS adaptation is an important process in inter-domain service mana g ement, since it can g uarantee the correct service provisionin g when unexpected events occur.However, in inter-domain environments, the human interference and the manual-based operations hamper the deployment of expeditious mechanisms to adapt the QoS of the services. This paper presents an approach based on SOA principles to perform QoS adaptation in these environments. This approach allows providers to determine the new QoS parameters, rene g otiate these parameters with other providers alon g the provisionin g path, update their contracts and enforce the chan g es in the equipment confi g uration in an automatic and on-demand fashion. The QoS adaptation process can be caused by technical (QoS violations, infrastructure malfunctions) or business (financial problems)issues. In addition, if a provider confi g uration in the provisionin g path already supports the new requirements, this provider is not affected by the adaptation, thus decreasin g the processin g time.

Imaging modalities to inform the detection and diagnosis of early caries

“…Cochrane Database of Systematic Reviews fluorescence diseased teeth respond di erently to sound teeth. There is potential for mineral loss to be quantified and used to aid the diagnostic decision and treatment pathway (Angmar-Månsson 2001;Matos 2011). Fluorescence is typically divided into laser fluorescence and light fluorescence (i.e.…”

“…Cochrane Database of Systematic Reviews Index tests were interpreted without the knowledge of the reference standard in 72 (94%) studies, and with the knowledge of the reference standard in four studies due to: the same assessor applying/conducting the index test and reference standard (Rathore 2012), the index test being interpreted with knowledge of the reference standard (Lazarchik 1995), the index test preceding the reference standard (Matos 2011;Mortensen 2018). A prespecified threshold for interpretation of the index test was used in 74 (96%) studies.…”

“…There was variation in the reference standards in three studies due to di erent reference standards for suspected enamel and dentine caries (enhanced visual examination or excavation). 17 studies (22%) excluded some observations from the analysis (Ariji 1998;Astvaldsdottir 2012;Bahrololoomi 2015;Bussaneli 2015;Ekstrand 2011;Erten 2005;Goel 2009;Hintze 1996;Jablonski-Momeni 2017;Ko 2015;Kockanat 2017;Matos 2011;Mialhe 2003;Mortensen 2018;Pontual 2010;Shimada 2014;Wenzel 2002). Where studies clearly reported that teeth did not receive the reference standard due to broken teeth during the sectioning procedure then this did not a ect the overall bias result for this domain.…”

Tests to detect and inform the diagnosis of root caries

“…Caries-induced changes in teeth alter the characteristics of its structure, causing diseased teeth to respond di erently to sound teeth when exposed to light-inducing fluorescence. There is potential for mineral loss to be quantified and used to aid the diagnostic decision and treatment pathway (Angmar-Månsson 2001;Matos 2011;Wicht 2002). Fluorescence is typically divided into laser fluorescence and light fluorescence (i.e.…”
