A Perturbation Approach to Continuous-Time Portfolio Selection Under Stochastic Investment Opportunities
2013
This paper studies portfolio selection in continuous-time models with stochastic investment opportunities. We consider asset allocation problems where preferences are specified as power utility derived from terminal wealth as well as consumption-savings problems with recursive utility Epstein-Zin preferences. The paper approximates the associated dynamic programming problem by perturbing the coefficients of the stochastic dynamics. We represent the Hamilton-Jacobi-Bellman equation as a series of partial differential equations that can be solved iteratively in closed-form through computer algebra software, at any desired accuracy.
Comparison of parallel implementation of some multi-level Schwarz methods for singularly perturbed parabolic problems
1999
Abstract Parallel multi-level algorithms combining a time discretization and an overlapping domain decomposition technique are applied to the numerical solution of singularly perturbed parabolic problems. Two methods based on the Schwarz alternating procedure are considered: a two-level method with auxiliary “correcting” subproblems as well as a three-level method with auxiliary “predicting” and “correcting” subproblems. Moreover, modifications of the methods using time extrapolation on subdomain interfaces are investigated. The emphasis is given to the description of the algorithms as well as their computer realization on a distributed memory multiprocessor computer. Numerical experiments …

A Prioritisation Model Aiding for the Solution of Illegal Buildings Problem
2016
In Italia, in particolare nelle aree del Sud, la costruzione di edifici e insediamenti abusivi è un problema importante e annoso che rimane irrisolto a dispetto di tre condoni edilizi. Ne deriva che le autorità pubbliche si trovano ad affrontare il problema della demolizione di un ingente numero di edifici, come prescritto dalla legislazione in materia. Ragioni di natura sociale e finanziaria impongono tuttavia l’esecuzione degli ordini di demolizione in maniera poco concentrata nel tempo, evidenziando il problema decisionale di stabilire un ordine di priorità relativo agli edifici interessati. Questa situazione preoccupante è divenuta oggetto di uno specifico disegno di legge che propone e…
Localizing the politics of privacy in communication and media research
2020
While previous communication and media research has largely focused on either studying privacy as personal boundary management or made efforts to investigate the structural (legal or economic) condition of privacy, we observe an emergent body of research on the political underpinnings of privacy linking both aspects. A pronounced understanding of the politics of privacy is however lacking. In this contribution, we set out to push this forward by mapping four communication and media perspectives on the political implications of privacy. In order to do so, we recur on Barry’s (2002) distinction of the political and the politics and outline linkages between individual and structural dimensions…
A case study on Finnish pupils' mathematical thinking: Problem solving and view of mathematics
2017
International audience; In this article, the mathematical thinking of four Finnish pupils is reported using two temporally different data sets: problem-solving processes and view of mathematics. While the pupils seem similar on the surface level (high achievers, successful problem solvers, enjoy mathematics, motivated to learn mathematics), a closer look at their problem-solving processes and view of mathematics reveal very different strengths and weaknesses in their mathematical thinking. Most of the similarities in this study were found in individual pupils' problem-solving processes and view of mathematics.
Learning to Teach Mathematics: Expanding the Role of Practicum as an Integrated Part of a Teacher Education Programme
2009
The premise of the 15th ICMI Study is that teachers are key to students' opportunities to learn mathematics. What teachers of mathematics know, care about, and do is a product of their experiences and socialization, together with the impact of their professional education. The Professional Education and Development of Teachers of Mathematics assembles important new international work- development, research, theory and practice - concerning the professional education of teachers of mathematics. As it examines critical areas to reveal what is known and what significant questions and problems warrant collective attention, the volume also contributes to the strengthening of the international co…
The RedTube copyright infringement affair in Germany: shame on who?
2015
Recently, tens of thousands of German Internet users were confronted with copyright infringement claims for allegedly watching porn clips on the streaming platform RedTube.com. The alleged copyright infringers received ‘Abmahnung’ cease and desist letters that gave them an opportunity to settle copyright infringements out of court by paying rights-holders €250 in compensation. While in cases relating to peer-to-peer file-sharing, the IP address of a peer can easily be identified,1 the RedTube case raises the question how consumers of a stream could be identified. In addition, it raises the question of whether the consumption of a stream is illegal under German law. Assuming that this is not…
Neural network approach to solving fuzzy nonlinear equations using Z-numbers
2020
In this article, the fuzzy property is described by means of the Z-number as the coefficients and variables of the fuzzy equations. This alteration for the fuzzy equation is appropriate for system modeling with Z-number parameters. In this article, the fuzzy equation with Z-number coefficients and variables is tended to be used as the models for the uncertain systems. The modeling issue related to the uncertain system is to obtain the Z-number coefficients and variables of the fuzzy equation. Nevertheless, it is extremely hard to get the Z-number coefficients of the fuzzy equations. In this article, in order to model the uncertain nonlinear systems, a novel structure of the multilayer neura…
