                         different instruments. To keep the systems operating in order to 
                         deliver the expected results, challenging issues arise: How to 
                         measure the instruments quality of service? How to adapt the 
                         system to continue operating in the event of unavailability? 
                         Self-adaptive systems are presented as a solution to adapt the 
                         system in response of changes in their operating environment. In 
                         this context, a framework is presented to provide self-adaptive 
                         support to software systems. The framework called Arctic Fox 
                         supports the entire adaptation life cycle: Monitoring, Analysis, 
                         Planning and Execution. An adaptation is triggered after metrics 
                         analysis and detection of service level agreements (SLA) 
                         violations, if so, an actuator (Executor) is activated in the 
                         system to promote the necessary architectural adaptations to keep 
                         the system serving the purpose for which it was designed.",
