A Multiparadigm Approach to Integrate Gestures and Sound in the Modeling Framework
- 2013
-
In: CEUR Workshop Proceedings, Vol. 112. ; , s. 57-66

Conference paper (peer-reviewed)abstract
- One of the essential means of supporting Human-MachineInteraction is a (software) language, exploited to input commands andreceive corresponding outputs in a well-dened manner. In the past,language creation and customization used to be accessible to softwaredevelopers only. But today, as software applications gain more ubiquity,these features tend to be more accessible to application users themselves.However, current language development techniques are still based on tra-ditional concepts of human-machine interaction, i.e. manipulating textand/or diagrams by means of more or less sophisticated keypads (e.g.mouse and keyboard).In this paper we propose to enhance the typical approach for dealing withlanguage intensive applications by widening available human-machine in-teractions to multiple modalities, including sounds, gestures, and theircombination. In particular, we adopt a Multi-Paradigm Modelling ap-proach in which the forms of interaction can be specied by means ofappropriate modelling techniques. The aim is to provide a more advancedhuman-machine interaction support for language intensive applications.

The maritime Subantarctic: a distinct periglacial environment
- 2003
-
In: Geomorphology. - : Elsevier. - 0169-555X .- 1872-695X. ; 52:1-2, s. 39-55
-
Journal article (peer-reviewed)abstract
- Recent research on slope processes and weathering on Marion Island has highlighted distinctive attributes of the maritime Subantarctic periglacial environment, compared to other periglacial environments. This is reflected morphologically by sorted stripe characteristics and stratified solifluction forms, but the wind factor and low diurnal temperature range also results in differences with other diurnal frost environments. Its hyper-maritime setting at low mean annual temperatures results in very high frost cycle frequencies, with associated effectiveness in surface sediment transport and patterned ground development. In addition, a high frequency of wetting and drying cycles is observed in rocks. Small seasonal temperature ranges and steep temperature profiles indicate a high sensitivity to climate change in the Subantarctic, as reflected in a rich relict periglacial record on most islands. This sensitivity appears absent in high tropical environments of low annual temperature range.

Modeling of hydrogen diffusion in piled slabs
- 2014
-
In: Advanced Materials Research. - : Trans Tech Publications. - 9783038350736 ; , s. 2201-2206
-
Conference paper (peer-reviewed)abstract
- Hydrogen is harmful in steel which makes it important to reduce the hydrogen content. Piling slabs after casting gives a slow cooling which increases the diffusion out of the steel. Finite element modeling has been used to simulate this process where hydrogen solubility and phase dependent diffusivity can be taken into account. The hydrogen diffusion model is using STEELTEMP® 2D for the thermal analysis. Measurements of temperature and hydrogen content in piled slabs have been done and the calculations are in good agreement. © (2014) Trans Tech Publications, Switzerland.

Simulation of Water Level Fluctuations in Kettle Holes Using a Time Series Model
- 2011
-
In: Wetlands. - : Springer Science and Business Media LLC. - 0277-5212 .- 1943-6246. ; 31:3, s. 511-520

Journal article (peer-reviewed)abstract
- Kettle holes are widespread in moraine landscapes. Their hydrological properties may be very vulnerable to changes in climatic conditions. To increase our knowledge of how kettle holes function and how they may be affected by climate change requires a model that can be applied to a variety of them regardless of their properties. We used the PIRFICT time series model to simulate the water levels in kettle holes over the last 50 years. For model calibration we applied time series of two-year lengths. We observed correlations between climate indices and water level statistics with a delayed response of one year. The results show a decrease in autumn low water levels and an increase in water level fluctuations. These effects correspond to observed increased summer evaporation and winter precipitation, and imply that the habitat quality dynamic of kettle holes depends on climatic conditions. With the prognosis of even warmer and dryer summers in Europe in the future, conservation strategies for kettle holes should include the effects of climate change.

An Architectural Approach to Support Online Updates of Software Product Lines
- 2011
-
In: 2011 Ninth Working IEEE/IFIP Conference on Software Architecture (WICSA). - : IEEE. ; , s. 204-213
-
Conference paper (peer-reviewed)abstract
- Despite the successes of software product lines (SPL), managing the evolution of a SPL remains difficult and error-prone. Our focus of evolution is on the concrete tasks integrators have to perform to update deployed SPL products, in particular products that require run-time updates with minimal interruption. The complexity of updating a deployed SPL product is caused by multiple interdependent concerns, including variability, traceability, versioning, availability, and correctness. Existing approaches typically focus on particular concerns while making abstraction of others, thus offering only partial solutions. An integrated approach that takes into account the different stakeholder concerns is lacking. In this paper, we present an architectural approach for updating SPL products that supports multiple concerns. The approach comprises of two complementary parts: (1) an update viewpoint that defines the conventions for constructing and using architecture views to deal with multiple update concerns; and (2) a supporting framework that provides an extensible infrastructure supporting integrators of a SPL. We evaluated the approach for an industrial SPL for logistic systems providing empirical evidence for its benefits and recommendations.
