Coupling dynamic simulation and interactive multiobjective optimization for complex problems: An APROS-NIMBUS case study
2014
Dynamic process simulators for plant-wide process simulation and multiobjective optimization tools can be used by industries as a means to cut costs and enhance profitability. Specifically, dynamic process simulators are useful in the process plant design phase, as they provide several benefits such as savings in time and costs. On the other hand, multiobjective optimization tools are useful in obtaining the best possible process designs when multiple conflicting objectives are to be optimized simultaneously. Here we concentrate on interactive multiobjective optimization. When multiobjective optimization methods are used in process design, they need an access to dynamic process simulators, …
Optimal Heating of an Indoor Swimming Pool
2020
This work presents the derivation of a model for the heating process of the air of a glass dome, where an indoor swimming pool is located in the bottom of the dome. The problem can be reduced from a three dimensional to a two dimensional one. The main goal is the formulation of a proper optimization problem for computing the optimal heating of the air after a given time. For that, the model of the heating process as a partial differential equation is formulated as well as the optimization problem subject to the time-dependent partial differential equation. This yields the optimal heating of the air under the glass dome such that the desired temperature distribution is attained after a given…
Spectral dynamics of incoherent waves with a noninstantaneous nonlinear response
2013
We study the influence of a constant background noise on the dynamics of spectral incoherent solitons, which are incoherent structures sustained by a noninstantaneous (Raman-like) nonlinearity. As the level of the noise background increases, the incoherent wave enters a novel nonlinear regime characterized by oscillatory dynamics of the incoherent spectrum, which develop within a spectral cone during the propagation. In contrast to the conventional Raman-like spectral red shift, such incoherent spectral dynamics can be characterized by a significant spectral blue shift. On the basis of the kinetic wave theory, we derive explicit analytical expressions of these incoherent oscillatory spectra…
Optimality of Increasing Stability for an Inverse Boundary Value Problem
2021
In this work we study the optimality of increasing stability of the inverse boundary value problem (IBVP) for the Schrödinger equation. The rigorous justification of increasing stability for the IBVP for the Schrödinger equation were established by Isakov [Discrete Contin. Dyn. Syst. Ser. S, 4 (2011), pp. 631--640] and by Isakov et al. [Inverse Problems and Applications, Contemp. Math. 615, American Math Society, Providence, RI, 2014, pp. 131--141]. In [Discrete Contin. Dyn. Syst. Ser. S, 4 (2011), pp. 631--640] and [Inverse Problems and Applications, Contemp. Math. 615, American Math Society, Providence, RI, 2014, pp. 131--141], the authors showed that the stability of this IBVP increases …
Il “diritto al silenzio” del potenziale testimone e l’incidente probatorio in sede di indagini difensive
2012
Trascorso più di un decennio dalla sua entrata in vigore, la riforma in materia di indagini difensive (l. 7 dicembre 2000, n. 397) continua a lasciare aperti numerosi aspetti problematici. Un nucleo cospicuo di dubbi irrisolti riguarda le evenienze che conseguono all’esercizio della facoltà di non rispondere da parte della persona chiamata a essere ascoltata nel corso dell’“inchiesta privata”. La figura di incidente probatorio prevista in questo contesto, “stravagante”, sia per le sue finalità, sia per le dinamiche che implica, ha impegnato la giurisprudenza a risolvere diverse questioni: in particolare, si è reso necessario stabilire il “peso” dell’iniziativa tendente a introdurre il pecul…

Pensamiento computacional y resolución de problemas en Educación Infantil: Una secuencia de enseñanza con el robot Bee-bot
2017
El término “pensamiento computacional” (Wing, 2006) guarda una estrecha relación con muchos de los procesos asociados a la resolución de problemas. Además de ocupar una posición privilegiada en los textos curriculares de las primeras edades escolares, la resolución de problemas es un elemento central de la enseñanza de las matemáticas. Concretamente, el aula de infantil es un escenario propicio para la aparición de situaciones estimulantes de resolución de problemas que ayuden a estructurar el pensamiento lógico- matemático del estudiante a la vez que desarrollen facultades intelectuales y estrategias heurísticas. Desde esta perspectiva se presenta una secuencia de enseñanza basada en el ro…
INFORMATION QUALITY PROBLEMS ON WEBSITES
2019
The goal of this publication is to identify and characterize the typical problems with information quality on websites, and to present exemplary remedies for those problems. In this article the information quality problems within their origins, as well as the consequences of using poor-quality information by the Internet user were defined. There were also presented ways of improving information quality - which should facilitate the information needed by producers/authors and the managers/administrators of services in or to find solutions to the remaining problems. The presented varied remedies are not all possible solutions to improving quality in the area of the WWW content and its infrast…

Il problem solving collaborativo: nuove traiettorie per la didattica
2022
Il capitolo, a partire da una disamina delle principali definizioni e dei più articolati framework teorici, intende soffermare la propria attenzione sulla dimensione sociale del CPS, declinata sia in termini collaborativi che comunicativi, per poi avviare una riflessione di natura pedagogico-didattica relativa all’implementazione e alla valutazione del CPS in contesti scolastici. The chapter, starting from an examination of the main definitions and the more articulated theoretical frameworks, intends to focus its attention on the social dimension of the CPS, declined both in collaborative and communicative terms, to then start a reflection of a pedagogical-didactic nature relating to the im…
