An abstract of the dissertation of Jie Huang for the Doctor of Philosophy in Computer Science presented October 9, 2006. Title: Efficient Support for Application-Specific Video Adaptation As video applications become more diverse, video must be adapted in different ways to meet the requirements of different applications when there are insufficient resources. In this dissertation, we address two...

Service-based systems increasingly need adaptation capabilities to agilely respond to unexpected changes in their business or execution environment. Although service orientation constitutes a promising approach to achieve this goal, current methods and technologies do not fully support automatic and dynamic adaptation at runtime. In turn, the Enterprise Service Bus (ESB), one of the preferred m...

Today, privacy is a key concept. It is also one which is rapidly evolving with technological advances, and there is no consensus on a single definition for it. In fact, the concept of privacy has been defined in many different ways, ranging from the “right to be left alone” to being a “commodity” that can be bought and sold. In the same time, powerful Ambient Intelligence (AmI) systems are bein...

Estimates of genetic gains and present performance of layers and broilers were reviewed Current and developing technologies pertinent to the breeding of layers and broilers were discussed with some of their assumptions and limitations. Under present methods, contemporary theory and selection technologies are critiqued Under developing technologies, selection for adaptation to production environ...

In most of software systems, designers try to include some self-adaptation facilities to increase the reliability of their systems. However, despite of the new methods and technologies in software engineering such as CBSE, or AOP, it is still difficult to talk about adaptation since adaptation policies might impact the architecture, the configuration data, and some extra-functional features as ...

This paper describes an adaptive technology of link insertion, used in educational hypermedia. It also presents an adaptive hypermedia system that uses this technology and the results of system evaluation in a real environment. The described adaptive system integrates elements of knowledge uncertainty into the user model. This model is then used for system adaptation, which builds on adaptive l...

Networks, terminals and users are becoming increasingly heterogeneous. In this context, the growing availability and usage of multimedia content have been raising the relevance of content adaptation technologies able to fulfill the needs associated to all usage conditions without multiplying the number of versions available for the same piece of content. For efficient and effective adaptations,...

A number of new technologies aimed at automating office work has been developed over the last 20 years with seemingly little impact on overall office productivity. We propose a conceptual model for technology adaptation for business process automation that stresses both technology-organization fit and technologyprocess fit. The goal of our study is to develop a systematic approach that addresse...
