Tool support for MOLA
2006
AbstractThe paper describes the MOLA Tool, which supports the model transformation language MOLA. MOLA Tool consists of two parts: MOLA definition environment and MOLA execution environment. MOLA definition environment is based on the GMF (Generic Modeling Framework) and contains graphical editors for metamodels and MOLA diagrams, as well as the MOLA compiler. The main component of MOLA execution environment is a MOLA virtual machine, which performs model transformations, using an SQL database as a repository. The execution environment may be used as a plug-in for Eclipse based modeling tools (e.g., IBM Rational RSA). The current status of the tool is truly academic.
Rhythmic and textural musical sequences differently influence syntax and semantic processing in children.
2020
International audience; Effects of music on language processing have been reported separately for syntax and for semantics. Previous studies have shown that regular musical rhythms can facilitate syntax processing and that semantic features of musical excerpts can inZluence semantic processing of words. It remains unclear whether musical parameters, such as rhythm and sound texture, may speciZically inZluence different components of linguistic processing. In the current study, two types of musical sequences (one focusing on rhythm and the other focusing on sound texture) were presented to children who were requested to perform a syntax or a semantic task thereafter. The results revealed tha…
Composing only by thought: Novel application of the P300 brain-computer interface.
2017
The P300 event-related potential is a well-known pattern in the electroencephalogram (EEG). This kind of brain signal is used for many different brain-computer interface (BCI) applications, e.g., spellers, environmental controllers, web browsers, or for painting. In recent times, BCI systems are mature enough to leave the laboratories to be used by the end-users, namely severely disabled people. Therefore, new challenges arise and the systems should be implemented and evaluated according to user-centered design (USD) guidelines. We developed and implemented a new system that utilizes the P300 pattern to compose music. Our Brain Composing system consists of three parts: the EEG acquisition d…
Experimental evidence for suspence as determinant of video game enjoyment
2009
Based on theoretical assumptions from film psychology and their application to video games, the hypothesis is tested that suspense is a major factor in video game enjoyment. A first-person shooter game was experimentally manipulated to create either a low level or a high level of suspense. Sixty-three participants were randomly assigned to experimental conditions; enjoyment was assessed after playing by a 10-item rating scale. Results support the assumption that suspense is a driver of video game enjoyment. © 2009 Mary Ann Liebert, Inc.
Manifestation of speech and language disorders in children with hearing impairment compared with children with specific language disorders.
2010
Children with hearing impairment (HI) often suffer from speech and language disorders. We wondered if the manifestation of these disorders resembled the ones in children with specific language impairment (SLI). Using matched pairs, we compared the manifestation of a speech and language disorder in 5- and 6-year-old children with HI and SLI. We looked at receptive language skills using the Reynell scales, the lexicon, syntax and morphology, output phonology, and phonological short-term memory. Receptive language skills were more impaired in HI children. No significant differences were recorded for all other domains. We conclude that language deficits that are at least partially caused by the…
Computational modeling in cognitive science: a manifesto for change.
2012
Computational modeling has long been one of the traditional pillars of cognitive science. Unfortunately, the computer models of cognition being developed today have not kept up with the enormous changes that have taken place in computer technology and, especially, in human-computer interfaces. For all intents and purposes, modeling is still done today as it was 25, or even 35, years ago. Everyone still programs in his or her own favorite programming language, source code is rarely made available, accessibility of models to non-programming researchers is essentially non-existent, and even for other modelers, the profusion of source code in a multitude of programming languages, written witho…
Closing the sensing-reasoning-actuating loop in resource-constrained WSANs through distributed symbolic processing
2015
Many issues in creating complex applications for pervasive environments are primarily due to the effort required to integrate perception, reasoning and actuating tasks in an efficient and homogeneous way, especially when the underlying infrastructure consists of wirelessly networked embedded devices. To mitigate the complexity of the actual implementation, satisfactory programming paradigms supporting the integration and coordination among heterogeneous devices are required. In this paper we show how a distributed symbolic processing approach that is particularly suited for resource constrained devices, such as the nodes of a Wireless Sensor and Actuator Network (WSAN), may be apt to the pu…
Categorizing networked services The role of intrinsic-, user network- and complement network attributes
2009
PurposeThis paper aims to investigate the properties and attributes of networked services and to propose a general categorization scheme for such services.Design/methodology/approachTwo separate studies were conducted to test the validity and applicability of the categorization scheme. First, industry experts categorized a set of pre‐selected mobile services based on the services' dominant source of value. Second, a large‐scale end‐user study of the same services was conducted for testing cross‐service differences between the proposed service categories in terms of what drives perceived customer value. It is argued that services can be categorized on the basis of whether their dominant sour…
A Scratch-based Graphical Policy Editor for XACML
2015
This paper proposes a policy-maker-friendly editor for the extensible Access Control Markup Language (XACML) based on the programming language Scratch. Scratch is a blocks-based programming language designed for teaching children programming, which allows users to build programs like a puzzle. We take this concept one step further with an XACML policy editor based on the graphic programming elements of Scratch implemented in Smalltalk. This allows for aiding the user on how to build policies by grouping blocks and operators that fit together and also indicating which blocks that will stick together. It simplifies building the XACML policies while still having an XACML “feel” of the graphic …
The Dirichlet-Bohr radius
2015
[EN] Denote by Ω(n) the number of prime divisors of n ∈ N (counted with multiplicities). For x ∈ N define the Dirichlet-Bohr radius P L(x) to be the best r > 0 such that for every finite Dirichlet polynomial n≤x ann −s we have X n≤x |an|r Ω(n) ≤ sup t∈R X n≤x ann −it . We prove that the asymptotically correct order of L(x) is (log x) 1/4x −1/8 . Following Bohr’s vision our proof links the estimation of L(x) with classical Bohr radii for holomorphic functions in several variables. Moreover, we suggest a general setting which allows to translate various results on Bohr radii in a systematic way into results on Dirichlet-Bohr radii, and vice versa
