Modern software applications are subject to uncertain operating conditions, such as
dynamics in the availability of services and variations of system goals. Consequently …

Cloud computing has been regarded as an emerging approach to provisioning resources
and managing applications. It provides attractive features, such as an on-demand model …

Self-adaptation is a first class concern for cloud applications, which should be able to
withstand diverse runtime changes. Variations are simultaneously happening both at the …

Abstract Dynamic Voltage and Frequency Scaling (DVFS), CPU pinning, horizontal, and
vertical scaling, are four techniques that have been proposed as actuators to control the …

It is common for cloud data centers meeting unexpected loads like request bursts, which
may lead to overloaded situation and performance degradation. Dynamic Voltage …

We focus on improving resilience of cloud services (eg, e-commerce website), when
correlated or cascading failures lead to computing capacity shortage. We study how to …

Programmers who are blind use a screen reader to speak source code one word at a time,
as though the code were text. For example," float f= 5.23;" can be read as" float f equals five …

Control theory has proven to be a practical approach for the design and implementation of
controllers, which does not inherit the problems of non-control theoretic controllers due to its …

Control theory has contributed a set of foundational techniques to handle “change” at
runtime in software applications. These techniques however have fundamental limitations as …

Cloud applications are often subject to unexpected events like flashcrowds and hardware
failures. Users that expect a predictable behavior may abandon an unresponsive application …
