Dynamical analysis of electron transport in RF cavities and photomultipliers tubes
2021
El objetivo de este trabajo es el estudio de la dinámica de haces y corrientes de electrones en cavidades aceleradoras de radiofrecuencia (RF) y en tubos fotomultiplicadores. Por una parte, los haces de electrones presentan una gran importancia histórica tanto en aplicaciones directas (televisiones, hornos de microondas, tratamiento del cáncer), como en la generación de radiación sincrotrón. La última generación de fuentes de rayos X muy brillantes se basa en los láseres de electrones libres (XFEL). No obstante, para producir los haces de electrones que emitirán dichos rayos X como radiación sincrotrón, se necesitan campos eléctricos de gran intensidad lo que produce que, debido a la emisió…
Linee guida per la valutazione di aziende sequestrate e confiscate alla criminalità organizzata
2020
L'articolo presenta "Le Linee guida per la valutazione di aziende sequestrate e confiscate" alla criminalità organizzata, evidenziando alcuni criteri per guidare la scelta del metodo di valutazione appropriato e suggerendo l'inclusione di una prospettiva di stakeholder negli studi di valutazione aziendale. The article presents "The Guidelines for the business valuation of seized and confiscated firms” from the organized crime, by pointing out some criteria to guide the selection of the appropriate valuation method and suggesting the inclusion of a stakeholder perspective in the business valuation studies.
Linee guida per la valutazione di aziende sequestrate e confiscate
2020
Le linee guida mirano ad analizzare le specificità delle aziende sequestrate e confiscate ai fini del processo di stima del valore di tali delicate realtà aziendali, esaltando in particolare come l’applicazione del metodo valutativo costituisca solo una fase del più ampio processo di stima, che deve necessariamente considerare elementi qualitativi, ma anche quantitativi di difficile ponderazione.
A black-box, general purpose quadratic self-consistent field code with and without Cholesky Decomposition of the two-electron integrals
2021
We present the implementation of a quadratically convergent self-consistent field (QCSCF) algorithm based on an adaptive trust-radius optimisation scheme for restricted open-shell Hartree���Fock (ROHF), restricted Hartree���Fock (RHF), and unrestricted Hartree���Fock (UHF) references. The algorithm can exploit Cholesky decomposition (CD) of the two-electron integrals to allow calculations on larger systems. The most important feature of the QCSCF code lies in its black-box nature ��� probably the most important quality desired by a generic user. As shown for pilot applications, it does not require one to tune the self-consistent field (SCF) parameters (damping, Pulay's DIIS, and other simil…
Aquiescence produce methods bias?: A study across self-esteem scales
2011
Un exercici corrent a les escales d’autoestima és presentar ítems en la direcció del tret, així com ítems en el sentit oposat. Aquesta pràctica ha esdevés habitual donat la presència d’aquiescència, entesa com la tendència a respondre de manera afirmativa amb independència del contingut dels ítems. Existeix abundant evidència a la literatura que el seu ús genera variància de mètode, fent aparéixer efectes de mètode no associats amb els trets d’interés. En aquest sentit, la present investigació pretén ampliar l’evidència i l’estudi de l’efecte de mètode associat als ítems negatius en el context de les escales d’autoestima. Es valora si aquest es presenta, no només quan l’autoestima es mesura…
The Dynamic Relationship between Response Processes and Self-Regulation in Critical Thinking Assessments
2021
Our aim was to explore higher education students’ response and self-regulatory processes plus the relationship between these, as evidenced in two types of performance-based critical thinking tasks included in the Collegiate Learning Assessment (CLA+) International instrument. The data collection consisted of 20 cognitive laboratories. The data were analyzed using a qualitative approach. The tasks were found to trigger different response and self-regulatory processes. Overall, the performance task evoked more holistic processes than the selected-response questions, in which students’ processes were more question-oriented. The results also indicated the entanglement of students’ response and …
Osallistava sävellytysmenetelmä musiikinopetukseen : peruskoulun opetussuunnitelman 2014 tavoitteita ja oppimisen ydinmetaforia toteuttamassa
2017
In my case study, I used two composing tasks to examine how the inclusive composing method (OSM) I have developed promotes the achievement of the aims of the new core curriculum for basic education 2014 and realises the core metaphors of learning. I have created a learning triangle tool to determine how the musical contents, the principles for developing working culture and the goals of music teaching, transversal competences and national education are linked with the latter. In addition to participation and the gaining and creation of knowledge, I included operative competences in these core metaphors. I examined the means OSM offers to evaluate how the students achieve the aims of musical…
Comment on "Measuring the flow resistance of submerged grass"
2004
In this short note, the experimental data of Wilson and Horritt (2002.Hydrological Processes16: 2589–2598), jointlywith the measurements by Kouwenet al. (1969.Journal of Irrigation and Drainage Division, ASCE95: 329–342)and by Raffaelliet al. (2002 InProceedings XXVIII Convegno di Idraulica e Costruzioni Idrauliche, Cosenza, Italy;223–230), arefirstly used to test Kouwen’s approach. All experimental data are then used to calibrate aflow resistanceequation that was theoretically deduced by dimensional analysis and self-similarity theory
Automated Detection of Microaneurysms Using Scale-Adapted Blob Analysis and Semi-Supervised Learning
2014
International audience; Despite several attempts, automated detection of microaneurysm (MA) from digital fundus images still remains to be an open issue. This is due to the subtle nature of MAs against the surrounding tissues. In this paper, the microaneurysm detection problem is modeled as finding interest regions or blobs from an image and an automatic local-scale selection technique is presented. Several scale-adapted region descriptors are then introduced to characterize these blob regions. A semi-supervised based learning approach, which requires few manually annotated learning examples, is also proposed to train a classifier to detect true MAs. The developed system is built using only…
High precision numerical approach for Davey–Stewartson II type equations for Schwartz class initial data
2020
We present an efficient high-precision numerical approach for Davey–Stewartson (DS) II type equa- tions, treating initial data from the Schwartz class of smooth, rapidly decreasing functions. As with previous approaches, the presented code uses discrete Fourier transforms for the spatial dependence and Driscoll’s composite Runge–Kutta method for the time dependence. Since DS equations are non-local, nonlinear Schrödinger equations with a singular symbol for the non-locality, standard Fourier methods in practice only reach accuracy of the order of 10−6or less for typical examples. This was previously demonstrated for the defocusing integrable case by comparison with a numerical approach for …
