Asiantuntijat uusien toimintamallien oppijoina
2003
Työ muuttuu ja sitä kautta myös työssä tarvittavien toimintatapojen pitäisi muuttua. Ajattelumallien tai toimintatapojen muuttaminen ei ole aina helppoa, sillä käytössä olevat mallit rutinoituvat nopeasti. Ihmisillä ei ole kykyä, halua tai aikaa tarkastella omaa työtään uusien silmälasien läpi, arvioida tapojensa toimivuutta tai jopa kokonaan kyseenalaistaa niiden järkevyyttä. Mielenkiintoisen ratkaisun etsiä uusia toimintamalleja ennakkoluulottomasti edustaa seuraava esimerkki Englannista. – Artikkelissa kuvataan brittiläisessä sairaalassa toteutettua kehittämisprosessia, jossa lääkärien visuaalisen hahmottamisen apuna on käytetty taiteilijoita.
Analytical model for the long- distance tracer-transport in plants
2011
International audience; Recent investigations of long-distance transport in plants using non-invasive tracer techniques such as C radiolabeling monitored by positron emission tomography (PET) combined with magnetic resonance imaging (MRI) revealed the need of dedicated methods to allow a quantitative data analysis and comparison of such experiments. A mechanistic compartmental tracer transport model is presented, defined by a linear system of partial differential equations (PDEs). This model simplifies the complexity of axial transport and lateral exchanges in the transport pathways of plants (e.g. the phloem) by simulating transport and reversible exchange within three compartments using j…
A Multiple Surrogate Assisted Decomposition Based Evolutionary Algorithm for Expensive Multi/Many-Objective Optimization
2019
Many-objective optimization problems (MaOPs) contain four or more conflicting objectives to be optimized. A number of efficient decomposition-based evolutionary algorithms have been developed in the recent years to solve them. However, computationally expensive MaOPs have been scarcely investigated. Typically, surrogate-assisted methods have been used in the literature to tackle computationally expensive problems, but such studies have largely focused on problems with 1–3 objectives. In this paper, we present an approach called hybrid surrogate-assisted many-objective evolutionary algorithm to solve computationally expensive MaOPs. The key features of the approach include: 1) the use of mul…

rec. a R. Salsano, Michelstaedter tra D’Annunzio, Pirandello e il mondo della vita
2015
All’insegna di un’adorniana dialettica del negativo, non priva tuttavia di una riaffiorante tensione eroica, è il profilo intellettuale di Carlo Michelstaedter quale emerge da questa recente indagine critica di Roberto Salsano, da tempo impegnato a investigare il felice connubio di riflessione teorica e invenzione narrativa che contraddistingue i principali interpreti della modernità letteraria. E proprio la convergenza dei due motivi – la disamina dell’intellettuale novecentesco e l’attenzione ai procedimenti di scrittura ‘impura’ – si concreta in quest’analisi dello studioso, esemplare non soltanto per la proposta interpretativa, ma anche per il solido impianto metodologico, che privilegi…
Możliwości energetycznego wykorzystania biomasy mikroalg
2016
Niniejsze opracowanie przedstawia możliwości zastosowania mikroalg do produkcji biopaliw III generacji - biodiesla, bioetanolu i biowodoru. Opisano parametry - CO2, temperatura, pH, światło i inne - zapewniające optymalne warunki hodowli mikroalg w fotobioreaktorach. Dokonano charakterystyki fotobioreaktorów, pod kątem ich przydatności do hodowli mikroalg na cele energetyczne. Przedstawiono metody termochemicznego i biochemicznego przetwarzania biomasy glonów stosowane do produkcji poszczególnych biopaliw.
Synthesis of Biocompatible and Biodegradable Polyamidoamines Microgels via a Simple and Reliable Statistical Approach.
2022
Polyamidoamines (PAAs) are biocompatible and biodegradable polymers with a huge potential as biomaterials for pharmaceutical applications. They are obtained by the step-wise aza-Michael polyaddition of bifunctional or multifunctional amines with bisacrylamides in water. To the best of our knowledge, no synthetic protocols leading to hyperbranched PAAs as well as PAA microgels have been published so far. To fill this gap, a statistical approach was established in this work to fine-tune the aza-Michael polyaddition stoichiometry when a multifunctional co-monomer (bf) is added to a mixture of bifunctional monomers with complementary functions (a2 + b2), possibly even in presence of a monofunct…
Modelling the effect of porosity on the mechanical properties of unidirectional composites. The case of thick-walled pressure vessels
2018
International audience; The present article highlights morphological features present in composite pressure vessels. The use of X-ray microtomography provides three-dimensional information about the voids in a large thick-walled type 3 pressure vessel at the mesoscopic scale. The observations show that the porosity structure depends strongly on composite thickness and orientation. A numerical approach is proposed to model realistically the damage phenomena in pressure vessels.
