Few studies have been conducted on the quality of service provided by the organizations responsible of providing dial-a-ride services for people with reduced mobility. In order to study quality in such contexts, the paper first defines what is meant by “quality” in the service sector. The difference between quality and satisfaction is then discussed, and the most well-known scales of measuremen...

Data quality management is a pressing issue in the adoption and implementation of Business Intelligence system in every organisation. We believe that an extensive metadata infrastructure is the primary technical solution for management of data quality in Business Intelligence. We derived a set of data quality dimensions by carefully examining the data quality management principles and current B...

Federation of Cloud services is notably landing interests from both Cloud providers and consumers. Cloud providers nowadays are required to form federations to remain competitive, and sustain their market share. Cloud consumers however seek optimized services from Clouds federation. They strive to maximize their satisfaction level, which is often measured by Quality of Service (QoS). Federation...

The focus of this paper is the quality assurance process for the bachelor program in the School of Computer Science at Reykjavik University, which is a combination of outcomeand process-oriented quality assurance. Faculty members and employers of graduates provided information for the quality assessment. The results provide both detailed quantitative data and more qualitative information that g...

There has been widespread interest within institutions of higher education to measure learning outcomes. This has resulted in considerable debate on how to best define, measure, and achieve quality learning outcomes assessment. Yet, there has been no development of electronic processes and tools for continuous program assessment and feedback. This project addresses this challenge, with a $200K ...

High level data quality and the management of ensuring data quality is one of the key success factors for Data Warehousing projects. The following article describes an approach for Data Quality Management, which is based on theories as well as practical experiences. Starting from effects of insufficient data quality in practice, a definition for information, data and data quality will be worked...

Dans ce travail, nous montrons comment mettre en œuvre la gestion des ressources et la garantie de QoS (Quality of Service) dans l’interdomaine en utilisant le modèle en stock [1]. Dans [1], nous avons appliqué un modèle distribué pour l’établissement des SLAs (Service Level Agreement) entre les opérateurs pour l’achat des routes avec une garantie de QoS et des résultats significatifs ont été o...

The Cloud Bank model, which is derived from Grid bank [1], is a kind of commerce model of cloud computing that provides pay-as-you-go computing resources. In this model, Cloud Bank is an agent platform of resource transaction. Cloud computing uses the concept of service level agreement (S LA) to control the use and receipt of computing resources from, and by, Cloud Bank. As computing resources ...

The overall image quality benefits substantially from good reproduction of black tones. Modern displays feature relatively low black level, making them capable rendering good dark tones. However, it is not clear if the black level of those displays is sufficient to produce a “absolute black” color, which appears no brighter than an arbitrary dark surface. To find the luminance necessary to invo...

Purpose of this paper In this paper a brief overview of some proposals of portal quality models is presented and a comparative study is carried out with the objective of establishing the main differences between them, along with their common aspects. Design/methodology/approach In order to compare the different portal quality models, their main characteristics have been analysed and specially, ...
