In real-time control system, output jitter of a task is important when feedback control loops are implemented as execution of periodic tasks. Output jitter refers to the variation of response time of a periodic task. For the stability of the control system, output jitter should be reduced. This paper aims to reduce the output jitter of real-time tasks under EDF scheduling. The proposed scheme d...

Evaluating the quality of language output tasks such as Machine Translation (MT) and Automatic Summarisation (AS) is a challenging topic in Natural Language Processing (NLP). Recently, techniques focusing only on the use of outputs of the systems and source information have been investigated. In MT, this is referred to as Quality Estimation (QE), an approach that uses machine learning technique...

We define a timing language that supports the design and implementation of embedded control software. The language is inspired by the Logical Execution Time (LET) paradigm of Giotto, but combines it with classical precedence constraints on tasks. A program specifies multiple modes of operation, where each mode consists of a set of periodically activated sensors, actuators, tasks, and mode switc...

How do English as a lingua franca (ELF) speakers achieve multimodal cohesion on the basis of their specific interests and cultural backgrounds? From a dialogic and collaborative view of communication, this study focuses on how verbal and nonverbal modes cohere together during intercultural conversations. The data include approximately 160-minute transcribed video recordings of ELF interactions ...

The main objective of this paper is to describe collaborative technology called LibreSource and how it is used to implement an innovative learning/teaching activity designed for software engineering students. From the educational perspective, this educational activity is based on the principles of problem-based learning and the latest Learning Design theory. The main objective of this activity ...

This paper presents an approach for the integration of domain related elements and operational semantics into collaborative environments based on visual languages. This integration allows for supporting domain specific collaborative tasks, e.g. in the area of “collaborative discovery learning” in science education, by integrating data modelling with generic discussion support. A special focus i...

As Schmidt (2008) states, deeper engagement with new vocabulary as induced by tasks clearly increases the chances of learning those words. This engagement is theoretically clarified by the involvement load hypothesis (ILH, Laufer and Hulstijn, 2001), based on which the involvement index of each task can be measured. The present study was designed to test ILH by evaluating the impact of 4 differ...
