This paper examines the use of mobile devices for language learning. In particular we consider how different multimedia and interface modalities can be used to facilitate mobile language learning. The use of multimedia is considered within the context of Second Language Acquisition (SLA) and Computer Assisted Language Learning (CALL) theories. In particular, we examine the Interaction Framework...

Monitoring services are an essential component of large-scale computing infrastructures due to providing information which can be used by humans as well as applications to closely follow the progress of computations, to evaluate the performance of ongoing computing, etc. However, the users are usually left alone with performance measurements as to the interpreting and detecting of execution fla...

(1) Background: Cloud storage is often required for successful operation of novel smart applications, relying on data produced by the Internet Things (IoT) devices. Big Data processing tasks and management operations such applications require high Quality Service (QoS) guarantees, requiring an Edge/Fog computing approach. Additionally, users specific guarantees in form Level Agreements (SLAs) s...

We describe two algorithms for finding representatives of the nilpotent orbits of a θ-group. The algorithms have been implemented in the computer algebra system GAP (inside the package SLA). We comment on their performance, and we apply the algorithms to obtain lists of N-regular automorphisms of simple Lie algebras of exceptional type.

In the Electronic Funds Transfer (EFT) Systems, faults can cause severe degradation on the performance of this system. Thus, modelling the performance of EFT system without considering dependability aspects can cause inaccurate results. This paper presents a stochastic model for evaluating performance of processing and storage infrastructures of the EFT system. This work also presents a model f...

Software systems built by composing existing services are more and more capturing the interest of researchers and practitioners. The envisaged long term scenario is that services, offered by some competing providers, are chosen by some consumers and used for their own purpose, possibly, in conjunction with other services. In the case the consumer is not anymore satisfied by the performance of s...

Despite the growing number of research studies in recent years, what is known about child second language acquisition (SLA) remains by and large a fraction of what is still to be known. In the present review, child SLA is defined as pertinent to both second language (L2) and sequential bilingual learners between the ages of two and twelve. Studies undertaken over the past 15 years are subdivide...

Passage-end calculations are a new style of passage measurement for eXtended Stochastic Probes (XSP) [1] which add the ability to split the analysis into several cases depending on conditions which hold at the end of a passage. This makes it possible to separate successful responses to a request from negative responses, timeouts or other failures. This allows the expression of service level agr...
