With the rapid development of information technology, it is inevitable that the distributed mobile computing will evolve to the pervasive computing gradually whose final goal is fusing the information space composed of computers with the physical space in which the people are working and living in. Furthermore, with the development of SOA, more and more pervasive applications have been composed...

The live migration of Virtual Machines (VMs) is a key technology in server virtualization solutions used to deploy Infrastructure-as-a-Service (IaaS) clouds. This process, on one hand, increases the elasticity, fault tolerance, and maintainability in the virtual environment. On the other hand, it increases the security challenges in cloud environments, especially when the migration is performed...

QoS-aware Web Service Selection is a crucially important issue in Service Oriented Communication which enables communication by integrating communication web services over Internet. Because of the growing number of candidate web services that provide the same functionality but differ in Quality of Service (QoS), it brings more challenges to select a combination of composite services with optima...

Modern IT systems have highly distributed and dynamic architectures composed of loosely-coupled services typically deployed on virtualized infrastructures. Managing system resources in such environments to ensure acceptable endto-end application Quality-of-Service (QoS) while at the same time optimizing resource utilization and energy efficiency is a challenge. The adoption of Cloud Computing t...

Keeping pace with the continuous changes and innovations in the field of English language teaching is considered to be a necessity for the quality of teachers' teaching. There are numerous approaches to teacher development, among which self-initiated development stands as one of the noticeable trends. Although teacher development is crucial for the quality of education, it appears that there ar...
