Corners in non-equiregular sub-Riemannian manifolds

2014

We prove that in a class of non-equiregular sub-Riemannian manifolds corners are not length minimizing. This extends the results of (G.P. Leonardi and R. Monti, Geom. Funct. Anal. 18 (2008) 552-582). As an application of our main result we complete and simplify the analysis in (R. Monti, Ann. Mat. Pura Appl. (2013)), showing that in a 4-dimensional sub-Riemannian structure suggested by Agrachev and Gauthier all length-minimizing curves are smooth. Mathematics Subject Classification. 53C17, 49K21, 49J15.

BREVI NOTE SULL'ONERE DELLA PROVA NEL PROCESSO TRIBUTARIO

2019

La regola dell’onere della prova costituisce un pilastro fondamentale in ogni disciplina processuale. Essa si sviluppa in una molteplicita' di principi attraverso i quali il processo persegue la sua funzione, la ricerca della verita'. Nel processo tributario l’applicazione della regola dell’onere della prova non sempre appare ispirata al principio del giusto processo ed al contribuente a volte è richiesto di offrire una prova che va oltre le sue possibilita'.

Settore IUS/12 - Diritto TributarioThe burden of proof is a cornerstone in procedural rules which takes with it several principles aimed at ensuring the trial purpose to pursuit the truth. Procedural rules in tax law recognize taxpayer’s right to a due process but often in judicial decisions the burden of proof doesn’t seem distributed evenly and he is asked to provide a very difficult proof.

EM Based Synthesis and Design of Bandpass Waveguide Filters Including Manufacturing Effects with FEST3D

2011

This article aims at the industry interest on automated design tools that are able to take into account manufacturing effects. First, an efficient design strategy for bandpass waveguide filters including the rounded corners arising from low-cost manufacturing procedures is presented. This technique is based on a recent enhanced prototype and synthesis methodology able to consider the real structure parts. Using the resulting electromagnetic (EM)-based synthesis technique, an excellent structure is extracted, which requires, at most, only a slight final EM optimization. Second, this article presents analytical expressions providing error estimates for the different filter performances in ter…
