Automaattisten mittalaitteiden käyttö vesistöseurannassa : esimerkkinä Jyväsjärven tutkimuslautta Aino
2011
Vesistöseurannan automatisointi lisää huomattavasti saatavilla olevan tiedon määrää, mutta samalla automaattisten aineistojen laadunvarmennuksen tärkeys korostuu. Jyväskylän yliopiston tutkimuslautta Aino mittaa jatkuvatoimisesti mm. veden happipitoisuuden ja lämpötilan vertikaaliprofiilia Jyväsjärvellä. Lautan tulosten luotettavuutta tutkittiin automaattisten mittalaitteiden sekä manuaalisen mittauksen avulla. Lautalla mitattiin myös virtausten suuntaa ja nopeutta ADCP-virtausmittarilla. Virtaustiedot tarkensivat kerrostumisen purkautumisen kuvaamiseen käytettyjä lukuja. Eri mittalaitteiden tuottamat happipitoisuustulokset poikkesivat merkitsevästi toisistaan. Hapen automaattisessa mittaam…

High-Reynolds-number turbulent cavity flow using the lattice Boltzmann method
2018
We present a boundary condition scheme for the lattice Boltzmann method that has significantly improved stability for modeling turbulent flows while maintaining excellent parallel scalability. Simulations of a three-dimensional lid-driven cavity flow are found to be stable up to the unprecedented Reynolds number $\mathrm{Re}=5\ifmmode\times\else\texttimes\fi{}{10}^{4}$ for this setup. Excellent agreement with energy balance equations, computational and experimental results are shown. We quantify rises in the production of turbulence and turbulent drag, and determine peak locations of turbulent production.
Experimental evolution of genome architecture and complexity in an RNA virus
2016
Introducción La evolución de la arquitectura del genoma – las dimensiones y la organización del material hereditario de un organismo – es poco conocida. Existe una variación asombrosa en la arquitectura genómica entre diferentes organismos. Los virus tienden a tener genomas pequeños, con un mínimo de secuencias intergénicas y típicamente con genes solapantes, los cuales se cree son una forma de compresión del genoma que permite al virus incrementar su número de proteínas sin aumentar su tamaño. Los procariotas tienen genomas compactos, pero con secuencias intergénicas más largas que los virus, y los genes con solapamientos largos son escasos. Los eucariotas presentan una amplia gama de tama…

Anticipatory Postural Adjustments and kinematic arm features when postural stability is manipulated
2018
International audience; Beyond the classical paradigm that presents the Anticipatory Postural Adjustments (APAs) as a manner to create forces that counteract disturbances arising from the moving segment during a pointing task, there is a controversial discussion about the role APAs to facilitate the movement and perform a task accurately. In addition, arm kinematics features are classically used to infer the content of motor planning for the execution and the control of arm movements, The present study aimed to disentangle the conflicting role of APAs during an arm-pointing task in which the subjects reach a central diode that suddenly turns on, while their postural stability was manipulate…
An analytical-numerical study of dynamic stability of an axially moving elastic web
2015
This paper is devoted to a dynamic stability analysis of an axially moving elastic web, modelled as a panel (a plate undergoing cylindrical deformation). The results are directly applicable also to the travelling beam. In accordance with the dynamic approach of stability analysis, the problem of harmonic vi- brations is investigated via the study of the dependences of the system’s nat- ural frequencies on the problem parameters. Analytical implicit expressions for the solution curves, with respect to problem parameters, are derived for ranges of the parameter space where the natural frequencies are real-valued, corresponding to stable vibrations. Both axially tensioned and non-tensioned tra…
