Enactive methods towards situational learning - engaging people with intellectual and developmental disability in design
2022
In this paper we explore how enactive methods may support and enhance the design of mobile solutions for people with intellectual and developmental disabilities. Our project deals with supporting independent public transport and applies enactive methods in order to account for the interdependent nature of technology, disability, and environment. We staged three iterations of a bus workshop and one theatre workshop where real, everyday scenarios were acted out to gain tacit yet crucial insights. These enactive workshops and the prototype testing showed that transport activities are context dependent and unique to each individual. In our case, enactive methods revealed that independent public…
Palabras clave y léxico frecuente como indicadores de la mentira
2015
Aunque la creencia popular sostiene que el lenguaje no verbal es el mejor indicador a la hora de detectar la mentira, diferentes investigaciones han puesto de manifiesto que la combinacion de lenguaje verbal y no verbal ofrece mayores porcentajes de acierto en la deteccion del engano que el uso de uno solo de estos parametros. De hecho, existe evidencia cientifica de que el lenguaje verbal puede ser el mejor predictor del comportamiento no veraz. Para nuestra investigacion, hemos elegido 38 informantes de entre 17 y 19 anos, a los que se ha sometido a dos pruebas. En la primera de ellas, los informantes deben expresar la verdad o mentir ante una serie de preguntas previamente establecidas y…
Magnetic Monopole Search with the Full MoEDAL Trapping Detector in 13 TeV pp Collisions Interpreted in Photon-Fusion and Drell-Yan Production
2019
MoEDAL is designed to identify new physics in the form of stable or pseudostable highly ionizing particles produced in high-energy Large Hadron Collider (LHC) collisions. Here we update our previous search for magnetic monopoles in Run 2 using the full trapping detector with almost four times more material and almost twice more integrated luminosity. For the first time at the LHC, the data were interpreted in terms of photon-fusion monopole direct production in addition to the Drell-Yan-like mechanism. The MoEDAL trapping detector, consisting of 794 kg of aluminum samples installed in the forward and lateral regions, was exposed to 4.0 fb$^{-1}$ of 13 TeV proton-proton collisions at the LHC…
Supporting fine-grained generative model-driven evolution
2010
Published version of an article in the journal: Software and Systems Modeling. Also available on SpringerLink:http://dx.doi.org/10.1007/s10270-009-0144-1 In the standard generative Model-driven Architecture (MDA), adapting the models of an existing system requires re-generation and restarting of that system. This is due to a strong separation between the modeling environment and the runtime environment. Certain current approaches remove this separation, allowing a system to be changed smoothly when the model changes. These approaches are, however, based on interpretation of modeling information rather than on generation, as in MDA. This paper describes an architecture that supports fine-gra…
Robust H∞ Filtering for a Class of Complex Networks with Stochastic Packet Dropouts and Time Delays
2013
Published version of an article in the journal: The Scientific World Journal. Also available from the publisher at: http://dx.doi.org/10.1155/2014/560234 Open Access The robust H∞ filtering problem is investigated for a class of complex network systems which has stochastic packet dropouts and time delays, combined with disturbance inputs. The packet dropout phenomenon occurs in a random way and the occurrence probability for each measurement output node is governed by an individual random variable. Besides, the time delay phenomenon is assumed to occur in a nonlinear vector-valued function. We aim to design a filter such that the estimation error converges to zero exponentially in the mean …
CO rebinding kinetics and molecular dynamics simulations highlight dynamic regulation of internal cavities in human cytoglobin
2013
Abstract: Cytoglobin (Cygb) was recently discovered in the human genome and localized in different tissues. It was suggested to play tissue-specific protective roles, spanning from scavenging of reactive oxygen species in neurons to supplying oxygen to enzymes in fibroblasts. To shed light on the functioning of such versatile machinery, we have studied the processes supporting transport of gaseous heme ligands in Cygb. Carbon monoxide rebinding shows a complex kinetic pattern with several distinct reaction intermediates, reflecting rebinding from temporary docking sites, second order recombination, and formation (and dissociation) of a bis-histidyl heme hexacoordinated reaction intermediate…
Et introduksjonskurs til GeoGebra : en designstudie av introduksjonskurset med fokus på å lære å bruke i 1T i videregående skole
2016
Masteroppgave matematikkdidaktikk – Universitetet i Agder 2016 As a teacher, I have observed over the past years a change in focus on the use of tools in the teaching of mathematics. Starting in spring 2015 the use of digital tools by students will be a requirement in the examinations in mathematics at high school level. This means that teachers must be even more aware of how we can best help our students to master the use of such tools while refining their understanding of mathematics. The aim of my study was to find a way to introduce GeoGebra (a mathematical tool with options for dynamic geometry, for plotting functions, and for CAS) to students in grade 11. The introduction should be su…
Sustainable Infrastructure Projects: Systemic versus Traditional Delivery Models
2021
Sustainability involves multiple environmental, technical, social and economic factors, and such complex analysis requires systemic solutions. Delivery models are key to achieving system benefits and enhancing sustainable development in infrastructure investments. They define the phases of a project, incentive structures, risk sharing and the relationships among the actors in it. They are usually developed early in the project and determine the project dynamics and outcomes. We compared traditional delivery models with systemic ones. We identified and illustrated elements that differ between them through two cases. The contribution is an increased understanding of how systemic infrastructur…
Air pollution perception in ten countries during the COVID-19 pandemic.
2021
As largely documented in the literature, the stark restrictions enforced worldwide in 2020 to curb the COVID-19 pandemic also curtailed the production of air pollutants to some extent. This study investigates the perception of the air pollution as assessed by individuals located in ten countries: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the USA. The perceptions towards air quality were evaluated by employing an online survey administered in May 2020. Participants (N = 9394) in the ten countries expressed their opinions according to a Likert-scale response. A reduction in pollutant concentration was clearly perceived, albeit to a different extent, by all …
Effects of Biochar Addition on Rill Flow Resistance
2021
The development of rills on a hillslope whose soil is amended by biochar remains a topic to be developed. A theoretical rill flow resistance equation, obtained by the integration of a power velocity distribution, was assessed using available measurements at plot scale with a biochar added soil. The biochar was incorporated and mixed with the arable soil using a biochar content BC of 6 and 12 kg m−2. The developed analysis demonstrated that an accurate estimate of the velocity profile parameter Гv can be obtained by the proposed power equation using an exponent e of the Reynolds number which decreases for increasing BC values. This result pointed out that the increase of biochar content dump…
