Sequentially Forecasting Economic Indices Using Mixture Linear Combinations of EP Distributions
2021
This article displays an application of the statistical method moti- vated by Bruno de Finetti's operational subjective theory of probability. We use exchangeable forecasting distributions based on mixtures of linear com- binations of exponential power (EP) distributions to forecast the sequence of daily rates of return from the Dow-Jones index of stock prices over a 20 year period. The operational subjective statistical method for comparing distributions is quite different from that commonly used in data analysis, because it rejects the basic tenets underlying the practice of hypothesis test- ing. In its place, proper scoring rules for forecast distributions are used to assess the values o…
Partial Discharge Behaviour Evaluation on MOSFET Employed in Automotive Applications
2022
This paper is focused on the measurement of partial discharges in the Silicon Carbide MOSFET. The latter represents a recent developed power electronics device, which has improved characteristics compared to the traditional Silicon MOSFET. The new technology has been conceived in order to satisfy the new market needs. With the ever-increasing development of the electric mobility sector, the need for ever more performing electronic power devices grows. The main features provided by the Silicon Carbide device were found in literature and concern a great thermal conductivity, wide bandgap, high power and high working temperature. However, considering the high voltage at which these devices wor…
A PV plant simulator for testing MPPT techniques
2013
This paper introduces a versatile and reliable photovoltaic systems simulator. It includes the main components of a photovoltaic plant: a PV string and a PWM controlled boost chooper. The key feature of this simulator is the ability to consider different and non-uniform irradiation and temperature conditions (partial shading and partial heating of the strings). All the different I-V and P-V or P-I characteristics can then be determined in such non-uniform irradiation and temperature conditions, with the aim to try different MPPT algorithms. The simulator also allows to verify an enhanced version of the Incremental Conductance algorithm (IncCond) where, in order to reach the real absolute ma…

Uniform, Sobolev extension and quasiconformal circle domains
1991
This paper contributes to the theory of uniform domains and Sobolev extension domains. We present new features of these domains and exhibit numerous relations among them. We examine two types of Sobolev extension domains, demonstrate their equivalence for bounded domains and generalize known sufficient geometric conditions for them. We observe that in the plane essentially all of these domains possess the trait that there is a quasiconformal self-homeomorphism of the extended plane which maps a given domain conformally onto a circle domain. We establish a geometric condition enjoyed by these plane domains which characterizes them among all quasicircle domains having no large and no small bo…
An Itô Formula for rough partial differential equations and some applications
2020
AbstractWe investigate existence, uniqueness and regularity for solutions of rough parabolic equations of the form $\partial _{t}u-A_{t}u-f=(\dot X_{t}(x) \cdot \nabla + \dot Y_{t}(x))u$ ∂ t u − A t u − f = ( X ̇ t ( x ) ⋅ ∇ + Y ̇ t ( x ) ) u on $[0,T]\times \mathbb {R}^{d}.$ [ 0 , T ] × ℝ d . To do so, we introduce a concept of “differential rough driver”, which comes with a counterpart of the usual controlled paths spaces in rough paths theory, built on the Sobolev spaces Wk,p. We also define a natural notion of geometricity in this context, and show how it relates to a product formula for controlled paths. In the case of transport noise (i.e. when Y = 0), we use this framework to prove a…
The Fairness Principle, Reward, and Altruistic Behavior
2011
The goal of this study was to investigate the relationship between reward and altruism. It was hypothesized that the altruistic behavior of someone who has been asked for help will occur only after the person asking for help has been evaluated. As a result, if the situation of a person asking for help is perceived as less fortunate, help will be given even if no proportional award is received in return, according to a principle based on need that makes people feel they should help the needy. Results show that when the participants received an unfair award, they tended to offer much bigger donations only in the condition in which the other was perceived as less fortunate. jasp_749 1110..1120…
