Real-Time Power Flow Monitoring and Control System for Microgrids Integration in Islanded Scenarios
2019
This article presents an enhanced system for real-time power flow monitoring and control (PFMC) for microgrids integration in medium-voltage (MV) distribution networks. The developed solution includes both system architecture and the monitoring and control algorithms, and it has low implementation and installation costs. It is based on the use of hardware and software solutions previously proposed by the authors, i.e., a distributed measurement, a control and communication architecture, and a supervisory control and data acquisition (SCADA) software, which have been enhanced and integrated for the considered application. The SCADA implements a load flow (LF) algorithm for real-time power fl…
Kulttuurienvälisen tietoisuuden ja kieliasenteiden kehittyminen CLIL-opetuksessa
2018
CLIL (Content and Language Integrated Learning) has been claimed to create a positive attitude towards languages and language learning in general and to raise intercultural awareness. The studies on the topics have however remained scarce. This study examines the issue from former pupils’ perspective. The 24 participants, who received English-medium CLIL during their comprehensive school in the 1990s, were interviewed in-depth and the data were analysed qualitatively. Most participants felt that CLIL had had a very positive effect on their attitudes towards English. However, many considered that CLIL had partly been detrimental to their attitudes towards and learning of other languages. The…
Traditional studying for examination versus constructivist learning tasks: Do learning outcomes differ?
1998
ABSTRACT Students' learning outcomes on an educational psychology course which involved studying three textbooks were compared between a constructivist class without a final examination and a traditional class concluding with an examination. The constructivist group (n = 16) studied the coursebooks with the help of writing assignments, discussed their assignments in groups and wrote an essay. The control group (n = 23) read the books on their own, attended lectures and took an examination. Learning outcomes were investigated (1) as the students' subjective learning experiences; (2) as changes in the students' learning conceptions; and (3) as measured by a traditional examination in which th…
Early ERP Evidence for Children’s and Adult’s Sensitivity to Scalar Implicatures Triggered by Existential Quantifiers (Some)
2021
How quickly do children and adults interpret scalar lexical items in speech processing? The current study examined interpretation of the scalar terms some vs. all in contexts where either the stronger (some = not all) or the weaker interpretation was permissible (some allows all). Children and adults showed increased negative deflections in brain activity following the word some in some-infelicitous versus some-felicitous contexts. This effect was found as early as 100 ms across central electrode sites (in children), and 300–500 ms across left frontal, fronto-central, and centro-parietal electrode sites (in children and adults). These results strongly suggest that young children (aged betwe…
The interaction of language and thought in children's language acquisition: a crosslinguistic study
1997
The purpose of this research was to investigate the potential interaction of conceptual representations and linguistic systems in the process of language acquisition. Language–thought interactions were studied in 80 American, 48 Finnish and 48 Polish preschool children. The research focused on the conceptual and linguistic development of space and time. The spatial and temporal conceptual tasks were designed to measure the transition from experiential to inferential knowledge of space/time representations. In the linguistic domain, comprehension and production tests were used to evaluate the children's capacity to understand mono- and bi-referential location in space and time, where mono-re…
Analysis and approximation of one-dimensional scalar conservation laws with general point constraints on the flux
2016
We introduce and analyze a class of models with nonlocal point constraints for traffic flow through bottlenecks, such as exits in the context of pedestrians traffic and reduction of lanes on a road under construction in vehicular traffic. Constraints are defined based on data collected from non-local in space and/or in time observations of the flow. We propose a theoretical analysis and discretization framework that permits to include different data acquisition strategies; a numerical comparison is provided. Nonlocal constraint allows to model, e.g., the irrational behavior (" panic ") near the exit observed in dense crowds and the capacity drop at tollbooth in vehicular traffic. Existence …
Strategies for structure solution and refinement of small organic molecules from electron diffraction data and limitations of the simulation approach
1999
In recent years, a series of non-linear optically active bis(benzylidene) ketones have been synthesized and investigated by electron crystallography. In most cases, structure refinement was possible by combining electron diffraction analysis and quantum-mechanical calculations with maximum-entropy methods. However, when the torsional angles between the phenyl rings and the C=C double bonds are strongly affected by the crystal field, this method fails because packing-energy calculations are not sufficiently sensitive. This problem can be solved by refining the approximate model with SHELXL, if the data set is sufficiently accurate and the model close to the correct structure. Here it is show…
Differentiation in language and gesture use during early bilingual development of hearing children of Deaf parents
2014
Hearing children of Deaf parents simultaneously acquire sign language and spoken language, which have many structural differences and represent two different modalities. We video-recorded eight children every six months between the ages of 12 and 24 months during three different play sessions: with their Deaf parent, with the Deaf parent and a hearing adult, and with a hearing adult alone. Additionally, we collected data on their vocabulary development in both sign language and spoken language. Children as young as 12 months old accommodated their language use according to the language(s) of their interlocutor(s). Additionally, the children used a manual modality that included gestures more…
Facework and Prosocial Teasing in a Synchronous Video Communication Exchange
2019
This study centres on the analysis of prosocial teasing during a videoconference (telecollaboration) exchange between mixed-gender adolescent secondary school students from Spain and Germany. We contend that the provocative elements present in prosocial teasing activate a play frame, in Gregory Bateson’s terms, in which seemingly hostile face acts can be interpreted as playful behaviour. We argue that successful teasing can ultimately enhance the face of the teaser and that of the person being teased and thus build up rapport between them. Our analysis of the facework in the interaction during this telecollaboration exchange is based on Erwin Goffman’s notions of face, demeanour and deferen…
Qualifying Building Information Models with Multi-Agent System
2011
6 pages; International audience; This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from building information models. Our proposal is based on the IFC standard which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and set up 3D objects and elements of simulation scenarios. The result of this process dynamically generates the input files to the JaSIM environment that performs the simulation.
