Domain Specific Case Tool for ICT-Enabled Service Design
2014
One major problem in service design is the limited availability of information gathered during the development process. In particular, information on end-user requirements is difficult for designers, developers, and maintainers to access. Here, we provide a mechanism that supports the gathering and modeling of various types of information throughout the service and software development life cycle. As various existing tools focus on a particular part of the life cycle, essential information is not available, or it is more difficult to obtain in later stages. The linkage between information collected in the different stages is often lost. The implemented tool support enables the modeling of r…
Can back-projection fully resolve polarity indeterminacy of independent component analysis in study of event-related potential?
2011
a b s t r a c t In the study of event-related potentials (ERPs) using independent component analysis (ICA), it is a traditional way to project the extracted ERP component back to electrodes for correcting its scaling (magnitude and polarity) indeterminacy. However, ICA tends to be locally optimized in practice, and then, the back-projection of a component estimated by the ICA can possibly not fully correct its polarity at every electrode. We demonstrate this phenomenon from the view of the theoretical analysis and numerical simulations and suggest checking and modifying the abnormal polarity of the projected component in the electrode field before further analysis. Moreover, when several co…
Measuring syntactic complexity in learner Finnish
2020
In the study of complexity, accuracy and fluency (CAF), syntactic complexity can be measured by a multitude of measures. Traditionally, the measures are quantitative and they use production units such as words, clauses, T -units, and sentences. Despite the vast number o f measures available, many studies have used only one or two of them, or parallel ones tapping the same component of complexity. The present study explores syntactic complexity using seven frequently used quantitative complexity measures to gauge different facets of complexity in written learner Finnish. The data of the study consist of texts written by adult and adolescent language learners, and they cover proficiency level…
From conceptualization to constructions in Finnish as an L2 : a case study
2017
AbstractThis study traces the individual learning trajectories of an adult beginner L2 Finnish learner in expressing the extralinguistic concept of evaluation from a dynamic usage-based perspective. Our results provide support for the view of learner language as a dynamic system in which patterns wax and wane and in which a change in one component has the potential to affect the whole system. In the early stages of learning there was a strong preference to use lexical verbs first, and then adjectives. The study also shows that variability plays a role. Finally, the study confirms that the learning of L2 constructions is in some cases item based. However, another highly frequent and superfic…
Une ontologie formalisée du domaine des risques et des catastrophes
2010
(pour publication dans un ouvrage relatif à l'ANR Cosmagems sous la direction de D. Phan, ed. prévu Hermes-Lavoisier); Nous présentons une ontologie formalisée du domaine des risques et des catastrophes et un premier exercice de validation à partir du récit de P. Hadfield (1992) sur " le Grand Séisme de Kantô de 1923 ". Il s'agit essentiellement d'une ontologie conceptuelle qui permet de décrire les connaissances du domaine. Dans cette ontologie, nous distinguons la terminologie utilisée pour décrire ce qui s'est passé en dehors de tout jugement subjectif (par exemple, il y a eu 30 morts à la suite d'une inondation), de la qualification de ce qui s'est passé (c'est un accident, une catastro…
Sbateyl.org: A Virtual Space for Effective Language Training
2016
AbstractThe paper presents an ongoing European cross-institutional project on teaching young language learners whose aim is to develop a web-based in-service teacher education programme with a school-based follow-up component. The main focus of the project is to bring researchers and teachers together to establish an innovative professional procedure blending theory and practice. Based on the strategic partnership between one local university and one primary school from each participant country, the project aims to foster the professional advancement and teaching practices of primary school teachers. The article initially outlines the main theoretical and methodological issues in the field …
Uz amēbu sastāva izmaiņām balstīta ūdens līmeņa kvalitatīvā rekonstrukcija Bažu purva rietumdaļai pēdējiem 5500 gadiem
2021
Bakalaura darba mērķis ir, balstoties uz amēbu daudzveidību un amēbu sugu sastāva izmaiņām, veikt ūdens līmeņa kvalitatīvo rekonstrukciju Bažu purva rietumu daļai pēdējos 5500 gados. Mērķa sasniegšanai tika pētīti lauka darbos iegūtie Bažu purva kūdras nogulumu paraugi, lai noskaidrotu amēbu sastāvu konkrētajos nogulumos. Balstoties uz radioaktīvā oglekļa sfērisko izdedžu daļiņu datēšanas rezultātiem, tika izstrādāts dziļuma-vecuma modelis (hronoloģija) Bažu purva urbumam. Līdz 21 centimetru (cm) dziļumam iegūtie Bažu purva kūdras nogulumu paraugi tika pētīti ik pa vienam cm, bet sākot no 30 cm dziļumā iegūtajiem paraugiem – paraugi tika pētīti ik pēc desmit cm. Pētījumā 49 dažādos dziļumos…
