We would like to deeply thank the CERN Knowledge Transfer and Legal Service teams for their essential and extended support. Our appreciation also goes to the FLUKA.CERN Collaboration Board members for their strong commitment.
Adaptive meshes in computer graphics and model-based simulation
2006
Monet luonnonlait voidaan ilmaista matemaattisesti joko yhtenä yhtälönä tai yhtälöjärjestelmänä. Erityisesti differentiaaliyhtälöiden ratkaisu on tärkeä esimerkiksi mekaniikassa, biologiassa tai kemiassa esiin tuleva ongelma. Useimmissa tapauksissa ratkaisu tällaisiin yhtälöihin on tuntematon, joten se täytyy löytää käyttäen tietokonekoodia. Koska tietokoneet toimivat rajoitetulla tarkkuudella ja tietomäärällä, tietokoneella saatu ratkaisu on vain approksimaatio yhtälön ratkaisulle. Tämän epätarkan tiedon käyttö tietokoneavusteisessa tekniikassa voi johtaa laitteen toimintahäiriöihin. Onkin tärkeää saada kuva, kuinka hyvin tietokoneella saatu tulos edustaa tarkkaa ratkaisua.

Understanding altered contractile properties in advanced age : insights from a systematic muscle modelling approach
2023
Age-related alterations of skeletal muscle are numerous and present inconsistently, and the effect of their interaction on contractile performance can be nonintuitive. Hill-type muscle models predict muscle force according to well-characterised contractile phenomena. Coupled with simple, yet reasonably realistic activation dynamics, such models consist of parameters that are meaningfully linked to fundamental aspects of muscle excitation and contraction. We aimed to illustrate the utility of a muscle model for elucidating relevant mechanisms and predicting changes in output by simulating the individual and combined effects on isometric force of several known ageing-related adaptations. Simu…
Luurankolihassolun glykolyysin simulointi differentiaaliyhtälöillä
2015
Solun aineenvaihduntaa on hankala tutkia. Simulointi voi olla eräs ratkaisu ongelmaan. Tutkielma tarkastelee differentiaaliyhtälöihin perustuvaa luurankolihaksen glykolyysin simuloimista. Siihen on kehitetty 2000-luvulla glykolyysin reaktioiden empiirisiin mittaustuloksiin perustuvia malleja. Differentiaaliyhtälömallit soveltuvat hyvin simuloimiseen, ja suurinpana ongelmana voidaan pitää parametrien saatavuutta ja epävarmuutta. Cell metabolism is difficult to investigate. Simulation can be one solution to the problem. This thesis examines differential equation based simulation of skeletal muscle glycolysis. For simulation, in 2000s it has been developed models based on empirical measurement…

Increasing the drying efficiency of cylinder drying
2011
This PhD Thesis concentrates on paper drying: first on the drying rate in a cylinder covered with fabric, enhanced using hot air impingement through the fabric, and its potential effects on paper quality, and second, on the heat transfer rate from hot steam to paper through the cylinder shell. Cylinder drying is a drying method where a heated surface in contact with paper causes water removal from the latter by evaporation. Impingement through the fabric of hot air has been suggested to cause increase in the water removal and drying of paper. Increase in the drying rate by impingement of hot air was confirmed by laboratory tests and by simulations. In laboratory tests the increase in the dr…

Mappa di Comunità della Valle del Simeto
2011
Questo libro è la storia di una collaborazione tra persone, legate fra loro dall'amore per un luogo, finalizzata alla "pratica" di una idea di sviluppo del territorio diversa da quella che viene loro imposta quotidianamente dalle strutture decisionali consolidate. Il luogo in questione e' una delle aree paesaggisticamente piu' pregiate della Sicilia, la Valle del Simeto, in corrispondenza del versante sud occidentale del vulcano Etna; l'idea di sviluppo che viene rigettata e' quella che, in passato, ha visto il materializzarsi di progetti di costruzione di impianti industriali altamente inquinanti lungo il corso del fiume Simeto; la "pratica" messa in campo dalla cittadinanza attiva simetin…
