Extending PluTo for Multiple Devices by Integrating OpenACC

2018

For many years now, processor vendors increased the performance of their devices by adding more cores and wider vectorization units to their CPUs instead of scaling up the processors' clock frequency. Moreover, GPUs became popular for solving problems with even more parallel compute power. To exploit the full potential of modern compute devices, specific codes are necessary which are often coded in a hardware-specific manner. Usually, the codes for CPUs are not usable for GPUs and vice versa. The programming API OpenACC tries to close this gap by enabling one code-base to be suitable and optimized for many devices. Nevertheless, OpenACC is rarely used by `standard programmers' and while dif…

The Effects of Multiple‐Exposure Textual Enhancement on Child L2 Learners’ Development in Derivational Morphology: A Multi‐Site Study

Combining Machine Translated Sentence Chunks from Multiple MT Systems

2018

This paper presents a hybrid machine translation (HMT) system that pursues syntactic analysis to acquire phrases of source sentences, translates the phrases using multiple online machine translation (MT) system application program interfaces (APIs) and generates output by combining translated chunks to obtain the best possible translation. The aim of this study is to improve translation quality of English – Latvian texts over each of the individual MT APIs. The selection of the best translation hypothesis is done by calculating the perplexity for each hypothesis using an n-gram language model. The result is a phrase-based multi-system machine translation system that allows to improve MT out…

Semi-automated annotation of page-based documents within the Genre and Multimodality framework

2016

This paper describes ongoing work on a tool developed for annotating document images for their multimodal features and compiling this information into a corpus. The tool leverages open source computer vision and natural language processing libraries to describe the content and structure of multimodal documents and to generate multiple layers of XML annotation. The paper introduces the annotation schema, describes the document processing pipeline and concludes with a brief description of future work.

Collaborative Game‐play as a Site for Participation and Situated Learning of a Second Language

2009

This paper addresses additional language learning as rooted in participation in the social activity of collaborative game‐play. Building on a social‐interactional view of learning, it analyses some of the detailed practices through which players attend to a video game as the material and semiotic structure that shapes play and creates affordances for additional language learning. We describe how players engage with the language resources offered by the game, drawing on the vocabulary, constructions, prosodic features and utterances modelled on game dialogue, in building their own actions during collaborative play. With these resources, the players display their ongoing engagement with the g…

Eye Movement Analyses for Obtaining Readability Formula for Latvian Texts for Primary School

2017

To determine the difficulty of text, readability formulas can be used. The research was made to find readability formula for Latvian. Readability formulas for English were used as guidelines. The novelty was the use of eye movement tracking during reading to obtain quantitative data that lead to readability formula. Eye fixation durations were gathered during readability measurements. Average values of fixation durations were calculated to characterize texts and readers. 15 texts with various difficulty levels were composed for exposing them to readers. More than 300 children of grades 1 - 4 were participating in measurements. Average values of eye fixation durations of readers from a certa…

Marx's critique of ideology for discourse analysis: from analysis of ideologies to social critique

2018

The notion of ideology is related to social and material reality and especially to the processes of social reproduction. Therefore, the analysis of ideology seems to fall into the domain of discourse analysis. The analysis of language and practices of signification in social contexts constitutes the basic triangle of discourse analysis. However, the Marxist concept of ideology always refers to some kind of falsity, that ultimately enables the researcher to not only analyse but also to criticize ideologies. Ideologies are always in some way false, injust or inadequate. It is at this point that discourse analysts usually raise the most serious objections as they understand truth itself as a d…

From face-to-face to blended learning using ICT

2016

This study examines the development of the education model created in connection with the Master Studies in Mathematical Information Technology. The model has developed from the first stage, where there was only face-to-face teaching supported with Learning Management System, to a stage where studying is possible also fully in online and students may choose themselves how much to take advantage of technology in their studies. The examination of the development of the education model is made from the viewpoints of accessibility, increased role of technology and interaction. In earlier studies, the education model has been evaluated for example from the viewpoints of changes in the participat…

Using evaluation criteria and rubrics as learning tools in subtitling for the D/deaf and the hard of hearing

2018

This paper focuses on the use of evaluation criteria and rubrics as tools for training in an audiovisual translation mode: subtitling for the D/deaf and the hard of hearing (SDH). Following an introduction to the current conception of and research carried out on quality assurance and assessment both in the translation industry and academia, a brief overview of the assessment processes and instruments used in SDH university training and in the professional sector is provided. This is followed by a case study of SDH assessment practices in Spain. Two questionnaires were filled in by five service providers and 12 university trainers, and the data gathered has enabled a better understanding of …

Partition of Indicaxanthin in Membrane Biomimetic Systems. A Kinetic and Modeling Approach

2009

The solubilization site of indicaxanthin (Ind) in lipid bilayers was investigated by the kinetics of Ind oxidation by peroxyl radicals in water and in aqueous/L-alpha-dipalmitoyl-phosphatidylcholine (DPPC) vesicles, pH 7.4, and 37.0 and 48.0 degrees C, that is, in a gel-like and a crystal liquidlike bilayer state, respectively. The time-dependent Ind absorbance decay, matched with a successful simulation of the reaction kinetic mechanism by Gepasi software, supported a multistep pathway. Computer-assisted analysis allowed calculation of the rate constants associated with the reactions involved, the values of which decreased with increasing DPPC concentration. The binding constant calculated…
