Water-use efficiency and transpiration across European forests during the Anthropocene
2015
Considering the combined effects of CO2 fertilization and climate change drivers on plant physiology leads to a modest increase in simulated European forest transpiration in spite of the effects of CO2-induced stomatal closure. The Earth’s carbon and hydrologic cycles are intimately coupled by gas exchange through plant stomata1,2,3. However, uncertainties in the magnitude4,5,6 and consequences7,8 of the physiological responses9,10 of plants to elevated CO2 in natural environments hinders modelling of terrestrial water cycling and carbon storage11. Here we use annually resolved long-term δ13C tree-ring measurements across a European forest network to reconstruct the physiologically driven r…
Influence of a Cu–zirconia interface structure on CO2 adsorption and activation
2021
CO2 adsorption and activation on a catalyst are key elementary steps for CO2 conversion to various valuable products. In the present computational study, we screened different Cu–ZrO2 interface structures and analyzed the influence of the interface structure on CO2 binding strength using density functional theory calculations. Our results demonstrate that a Cu nanorod favors one position on both tetragonal and monoclinic ZrO2 surfaces, where the bottom Cu atoms are placed close to the lattice oxygens. In agreement with previous calculations, we find that CO2 prefers a bent bidentate configuration at the Cu–ZrO2 interface and the molecule is clearly activated being negatively charged. Strain…
Postcards and Supasigns : Extending Integrationist Theory Through the Creation of Interactive Digital Artworks
2007
Integrationism is a post-structuralist theory of language and communication. The theory has been applied to a groundbreaking analysis of writing as a form of communication where writing is teased apart from speech and realigned with spatial configurations in general. Although it has many practical applications, this view can be extremely difficult to comprehend when expressed as a very specific form of writing, that is, as written words on paper. A solution to this problem is offered by the creative interaction design of two digital artworks, Postcard From Tunis and Postcards From Writing. The works are interactive multimedia pieces that creatively express the integrationist theory of writi…
Status and Prospects of Kanki : An Open Source Cross-Platform Native iRODS Client Application
2016
The current state of development of project Kanki is discussed and some prospects for future development are laid out with reflection on the results of the research IT infrastructure project at the University of Jyväskylä. Kanki is a crossplatform native iRODS client application which was introduced to the iRODS community at the iRODS Users Group Meeting in 2015, and later released as open source. A total of 9 releases have been made, from which the latest 6 have been available in addition to the source code as pre-built binary packages for x86-64 CentOS Linux 6/7 and OS X 10.10+. The Kanki build environment at the University of Jyväskylä is running out of Jenkins continuous integration for…
Development of a Native Cross-Platform iRODS GUI Client
2015
This paper describes activities on the research IT infrastructure development project at the University of Jyväskylä. The main contribution is a cross-platform iRODS client application with a rich graphical user interface. The client application is fully native and builds from a single C++ codebase on all of the platforms on which iRODS 4.0 is supported. The application has a responsive UI with native look & feel and enables drag & drop integration to the desktop. This is made possible by basing the development of the client application on top of the Qt 5 framework and an object-oriented C++ framework for iRODS which is being developed with the client application. The objectoriented framewo…
Aesthetic Appeal and Visual Usability in Four Icon Design Eras
2016
Technological artefacts express time periods in their visual design. Due time, visual culture changes and thus affects the design of pictorial representations in technological products, such as icons in user interfaces. Previous research of temporal aspects in human-computer interaction has been focusing on particular interaction situations, but not on the effects of design eras on user experience. The influence of icon design styles of different eras on aesthetic and usability experiences was studied with the method of primed product comparisons. Affective preferences and their processing times were analysed in order to examine visual usability in terms of semantic distance and aesthetic a…
Variables cognitives i factors de personalitat dels subjectes amb millor control d’una Interfície Cervell Computadora
2022
Objectiu :La interrelació entre l’humà i la màquina en una tasca amb una Interficie Cervell-Computadora ( BCI de les sigles en anglès) es especialment transcendental. Hi ha subjectes incapaços d’aprendre a manipular-la( Illiteracy). El present treball analitza la influència del tipus de paradigma de control , les habilitats atencionals , els trets de personalitat i la resposta d’afrontament de la resposta davant el fracàs a l'hora d’utilitzar-la. Mètode: Hem emprat dues mostres de 89 i 191 estudiants de 1er i 2n curs de la Universitat de València en dos estudis consecutius els anys 2016 i 2017. S’han aplicat test de personalitat i qüestionaris sobre activitats rutinàries, avaluació atencion…
A Cognitive Architecture for Robotic Hand Posture Learning
2005
This paper deals with the design and implementation of a visual control of a robotic system composed of a dexterous hand and video camera. The aim of the proposed system is to reproduce the movements of a human hand in order to learn complex manipulation tasks or to interact with the user. A novel algorithm for robust and fast fingertips localization and tracking is presented. A suitable kinematic hand model is adopted to achieve a fast and acceptable solution to an inverse kinematics problem. The system is part of a cognitive architecture for posture learning that integrates the perceptions by a high-level representation of the scene and of the observed actions. The anthropomorphic robotic…
Assisting immersive virtual reality development with user experience design approach
2017
In our study we explored how to design a biography of a late Finnish artist as a VR experience. We conducted a development process assisted by user experience (UX) design methods, which increased the process efficiency, and resulted in a research prototype. Through previous research and our development process, we identified components affecting the user experience. These components are: Immersion, Presence, Disorientation, Sense of Control, Pleasantness, Exploration and Simulator Sickness. From our user study with 13 participants, we were able to draw implications that relate to these components. While the set of components could be incomplete or subject to change, shows that further resea…
The effects of user interface type on player immersion in first-person shooter games
2017
Videopelien vaikutuksia pelaajien käyttäytymiseen on tutkittu laajasti, kuten myös niitä tekijöitä jotka vaikuttavat pelaajien tyytyväisyyteen ja kiinnostukseen videopelejä kohtaan. Tästä huolimatta on puutetta julkisesti saatavilla olevasta empiirisestä tutkimuksesta, joka keskittyisi käyttöliittymän vaikutukseen pelaajan kokemaan immersioon pelin aikana sekä siihen, mikä käyttöliittymissä vaikuttaa immersion kokemuksen syntymiseen. Käyttöliittymät ensimmäisen persoonan kuvakulmasta olevissa videopeleissä voidaan jakaa kahteen eri tyyppiin, diegeettisiin ja epädiegeettisiin käyttöliittymiin. Nämä kaksi eri käyttöliittymätyyppiä saattavat vaikuttaa pelaajan kokemukseen eri tavoin. Parempi y…
