We demonstrate the bene ts of software shared mem ory protocols that adapt at run time to the memory access patterns observed in the applications This adaptation is automatic no user annotations are required and does not rely on compiler support or special hardware We in vestigate adaptation between single and multiple writer protocols dynamic aggregation of pages into a larger trans fer unit a...

This paper presents the application of a Voice Gender Normalization algorithm to the GSM Speech Codec and describes the refinements that can be made to the Codec as a result. By reducing the dynamic range of the speech signals entering the Codec gender specific adaptations can be made to the Codec to improve its performance in terms of subjective sound quality or its transmitted bit rate.

Long running applications often need to adapt due to changing requirements or changing environment. Typically, such adaptation is performed by dynamically adding or removing components. In these types of adaptation, components are often added to or removed from multiple processes in the system. While techniques for such adaptations have been extensively discussed in the literature, there is a l...

We describe an approach based upon software process technology to on-the-fly monitoring, redeployment, reconfiguration, and in general dynamic adaptation of distributed software applications. We choose the term dynamic adaptation to refer to modifications in structure and behavior that can be made to individual components, as well as sets thereof, or the overall target system configuration, suc...

We introduce a new programming language called INI, which eases the development of self-adaptive software. INI combines both rulebased and event-based programming paradigms, by allowing the definitions of rules that can be triggered by events. Besides a convenient language-level support for synchronization, the key point with INI events is that they come with a configuration layer, which is set...

A hallmark of human robust intelligence is the ability to flexibly and dynamically adapt behavior to the current situation. For dialog behavior, this entails adaptation to features of both the dialog partner (e.g., relationship, age, personality) and the dialog situation (e.g., task context, asynchronous interaction, limited modalities such as voice-only communication). We don’t completely unde...

Most service adaptation solutions follow an anticipated approach: the adaptation control is based on predefined service-specific rules and strategies. These solutions will not work correctly in a context that was not taken into account by predefined rules and strategies even if a large context diversity was considered. This paper presents a solution based on a context-service common representat...

Software Adaptation promotes the use of specific computational entities called adaptors that guarantee software components will interact in the right way, not only at the signature level, but also at the behavioral, semantic and service levels. Adaptation techniques have proceeded by computing adaptors for closed systems made up of a fixed set of components. This is not satisfactory when the sy...

In the present study, we explored adaptation to prism-displaced dynamic and static events under conditions of minimal information. Many of our interactions with the world are dynamic and involve reaching for or intercepting moving objects. The consequences (or feedback) of those interactions entail the presence or absence of physical contact with the moving objects. In this study, humans learne...

This paper presents a new approach for adapting a multimedia presentation into heterogeneous and dynamically changing environments. A novel media adaptation taxonomy is proposed that includes synchronized media optimization and scaling. The taxonomy incorporates multi-dimensional interaction between media, service requirements and presentation. Network properties, terminal types and integration...
