this study explored the effect of contrastive phrase resynthesis instruction ongaining the teachability hypothesis stages in self-paced versus time-constrained oralproduction and recognition. three groups (i.e., 23 learners) of high beginner femalelearners in an english language institute were randomly selected from a cohort oflearners. one group received contrastive metalinguistic instruction ...

The adoption of service-oriented architectures based on web services in industrial automation promises increased interoperability and flexibility. Since the development and deployment of web services requires in-depth programming knowledge, adequate tools to ease the work of automation engineers are required. In particular, the orchestration of existing web services to workflows is a challengin...

Commercial cloud offerings, such as Amazon’s EC2, let users allocate compute resources on demand, charging based on reserved time intervals. While this gives great flexibility to elastic applications, users lack guidance for choosing between multiple offerings, in order to complete their computations within given time and budget constraints. In this work, we present BaTS, our budget and timecon...

This paper introduces a new architecture called the Dynamic Cluster, which is a cluster of computers connected together over a wired and wireless network. The nodes can use any network technology to connect to the cluster. The communication protocol of the Dynamic Cluster includes the dynamic detection of nodes entering and exiting the cluster. The Dynamic Cluster would dynamically redistribute...

Real-time operating systems generally depend on some form of priority information for making scheduling decisions. Priorities may take the form of small integers or deadline times, for example, and the priorities indicate the preferred order for execution of the jobs. Unfortunately, most systems suffer from some degree of priority inversion where a high priority job must wait for a lower priori...

The Ethernet network is increasingly used for the industrial communications which are strongly timeconstrained. This paper presents both a method (based on the genetic algorithms) to design switched Ethernet architectures and a method (based on the network calculus) to evaluate these network architectures in term of maximum end-to-end delay.

The design of Real-Time (RT) applications is a difficult task since it must take into account the specification of time-constrained data and timeconstrained transactions. The design of these applications can be facilitated through the reuse of RT design patterns that improve software quality and capture RT domain knowledge and design expertise. However, the difficulty of RT design patterns comp...

In this article we focus on the co-creation of ideas. Through the use of concepts from collaborative learning and communication theory we suggest a model that will enable the cooperative nature of creative design tasks to emerge. Four objectives of the model are stated and elaborated on in the paper: that the model should be anchored in previous research; that it should allow for collaborative ...
