Macro-micro relationship in nanostructured functional composites
2012
This paper examines the results of the characterization of two functional composites: Poly(methyl methacrylate) (PMMA)-Ce:YAG (yttrium aluminium garnet doped with cerium) and PMMA-cobalt hexacyanoferrate (CoHCF). The composites were prepared as possible emitters in the fields of lighting thermal sensors. The prepared composites were char- acterized using transmission electron microscopy (TEM), nuclear magnetic resonance (NMR) spectroscopy, thermogravi- metric analysis (TGA), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) analyses to study the correlation between micro and macro characteristics. We found that the molecular interactions of the two different fill…
A cognitive/decision-making model of evaluation for ethical urban and building renewal
2009
Creativity is a strategic factor not only in the production sector, but also for planning, development and management of the city. The physical shape of the city is determined by the plan of buildings and settlements as a whole. Nevertheless, the functional and aesthetical criteria alone are inadequate, if you adopt the view of sustainability. In particular, from biological, ecological and economic points of view, the shape of the sustainable city is the result of a process of creative choice of traditional and innovative forms, materials and technologies that contribute to the quality of buildings and urban ambient. This principle applies a fortiori in cities interested by not-negligible p…
Emergent ultrafast phenomena in correlated oxides and heterostructures
2017
The possibility of investigating the dynamics of solids on timescales faster than the thermalization of the internal degrees of freedom has disclosed novel non-equilibrium phenomena that have no counterpart at equilibrium. Transition metal oxides (TMOs) provide an interesting playground in which the correlations among the charges in the metal $d$-orbitals give rise to a wealth of intriguing electronic and thermodynamic properties involving the spin, charge, lattice and orbital orders. Furthermore, the physical properties of TMOs can be engineered at the atomic level, thus providing the platform to investigate the transport phenomena on timescales of the order of the intrinsic decoherence ti…
Enhancing the Collaborative Governance in Post-disaster Reconstruction: A Dynamic Performance Management Approach
2020
The impact of natural disasters on human life was blatantly demonstrated through media reports of recent events such as the Ache tsunami in 2004, Hurricane Katrina in 2005, the Wenchuan Earthquake in 2008 and Tohoku Earthquake and Tsunami in 2010-2011. Rising from the rubbles, our societies strive to learn from the experiences of how to build a better life and avoid future catastrophes. Post-disaster reconstruction (PDR) plays a crucial role in providing a safer and more resilient living environment for people, particularly for those disaster victims. This thesis focused on how implementing a collaborative governance approach in post-disaster reconstruction can offer effective solutions to …
Temperature dependence of η / s of strongly interacting matter: Effects of the equation of state and the parametric form of ( η / s ) ( T )
2020
We investigate the temperature dependence of the shear viscosity to entropy density ratio η/s using a piecewise linear parametrization. To determine the optimal values of the parameters and the associated uncertainties, we perform a global Bayesian model-to-data comparison on Au+Au collisions at √sNN=200 GeV and Pb+Pb collisions at 2.76 TeV and 5.02 TeV, using a 2+1D hydrodynamical model with the Eskola-Kajantie-Ruuskanen-Tuominen (EKRT) initial state. We provide three new parametrizations of the equation of state (EoS) based on contemporary lattice results and hadron resonance gas, and use them and the widely used s95p parametrization to explore the uncertainty in the analysis due to the c…
Creative Network Communities in the Translocal Space of Digital Networks
2013
What should sociological research be in the age of Web 2.0? Considering that the task of “network sociology” is not only empirical research but also the interpretation of tendencies of the network culture, this research explores the rise of network communities within Eastern and Western Europe in the early Internet era. I coined the term creative networks to distinguish these early creative and social activities from today’s popular social networking. Thus I aimed to interpret the meaning of social action; the motivation of creative community actors, their main fields of activities and social organization forms; and the potential that these early developments contain for the future sustaina…
Business schools’ competitive strategies : whose goals, which aims?
2019
Purpose This study reviews the literature on business-school (b-school) competition and competitiveness to extend our understanding of b-schools’ competitive strategies. Design/methodology/approach Both content and network analysis were used in the examination of the scholarly discourse. Findings The analyses distinguish three literature streams. The first concentrates on resources, capabilities and competencies; the second focuses on measures of competitiveness; and the third includes competitive dynamics and strategy discourse. The analysis shows that the conceptions of competitiveness are quite coherent concerning resources, capabilities and competencies. However, in the “measures of com…
Koncepcja dynamicznych zdolności w budowaniu konkurencyjności łańcucha dostaw
2019
W ostatnich latach zauważalne jest stale postępujące i coraz bardziej wyraziste „osadzenie” problematyki logistyki i zarządzania łańcuchem dostaw w zasobowym nurcie zarządzania strategicznego. W nurcie tym podkreśla się kluczowe znaczenie potencjałów sukcesu, obejmujących m.in. zdolności, w tym tzw. dynamiczne zdolności, w budowaniu oraz wzmacnianiu długookresowej konkurencyjności przedsiębiorstw i łańcuchów dostaw. Celem artykułu jest przedstawienie możliwości wykorzystania koncepcji dynamicznych zdolności, obejmujących również zdolności związane ze sferą logistyki, w budowaniu konkurencyjności łańcucha dostaw. W szczególności zaprezentowano tu istotę konkurencyjności i jej podstawowe wyzn…
Linear ViscoElastic (LVE) Behaviour of Pure Bitumen via Fractional Model
2012
AbstractBy fitting experimental data from static creep/recovery carried out on pure bitumen, it is shown that the fractional model proposed enables the description of both creep and recovery behaviour with fewer parameters than those needed by other models in the literature. In particular, the model is fitted to experimental data of complex modulus |G*| and phase angle δ° obtained from Dynamic Mechanical Analysis. Lastly, it is demonstrated that when the fractional model is used, complex modulus isotherms for a range of frequencies can be created simply starting from isochronals at f = 1Hz.
Conduit dynamics and post explosion degassing on Stromboli: A combined UV camera and numerical modeling treatment
2016
Recent gas flux measurements have shown that Strombolian explosions are often followed by periods of elevated flux, or “gas codas,” with durations of order a minute. Here we present UV camera data from 200 events recorded at Stromboli volcano to constrain the nature of these codas for the first time, providing estimates for combined explosion plus coda SO2 masses of ≈18–225 kg. Numerical simulations of gas slug ascent show that substantial proportions of the initial gas mass can be distributed into a train of “daughter bubbles” released from the base of the slug, which we suggest, generate the codas, on bursting at the surface. This process could also cause transitioning of slugs into cap b…
