This paper describes approaches for dynamic software adaptation using runtime models of the software architecture. Software adaptation patterns consist of interaction models and state machine models that are used during dynamic software adaptation. Software adaptation and recovery concerns are off-loaded from components by incorporating them into connectors, which are responsible for dynamicall...

A new method was introduced for frothing characterization of flotation frothers. Method uses water recovery to develop a new frothability index named water recovery index (WRI). New index was determined for some commercial frothers and results were compared with dynamic frothability index (DFI). Results showed that water recovery index values follow the order of A-65 13016 s/mol > DF-250 6292.4...

A Self-Adaptive Recovery Net (SARN) is an extended Petri net model for specifying exceptional behavior in workflow systems. SARN caters for high-level recovery policies that are incorporated either with a single task or a set of tasks, called a recovery region. A recovery region delimits the part of the workflow from which the associated recovery policies take place. In this paper, we assume th...

Many distributed protocols arising in applications in on-line load balancing and dynamic resource allocation can be modeled by dynamic allocation processes related to the \balls into bin" problems. Traditionally the main focus of the research on dynamic allocation processes is on verifying whether a given process is stable, and if so, on analyzing its behavior in the limit (i.e., after suucient...

the effects of carbon content on the dynamic and static softening mechanisms of ti microalloy steels were investigated both in ferrite and austenite regions. the results obtained showed that recrystallization rate decreased as the percentage of carbon content was increased from 0.0035 to 0.110. this is due to the ti(cn) and tic precipitates and also the free carbon content. in the ferrite regio...
