A decomposition approach for multidimensional knapsacks with family-split penalties
2022
The optimization of Multidimensional Knapsacks with Family-Split Penalties has been introduced in the literature as a variant of the more classical Multidimensional Knapsack and Multi-Knapsack problems. This problem deals with a set of items partitioned in families, and when a single item is picked to maximize the utility, then all items in its family must be picked. Items from the same family can be assigned to different knapsacks, and in this situation split penalties are paid. This problem arises in real applications in various fields. This paper proposes a new exact and fast algorithm based on a specific Combinatorial Benders Cuts scheme. An extensive experimental campaign computational…

New degrees of freedom for differential forms on cubical meshes
2022
We consider new degrees of freedom for higher order differential forms on cubical meshes. The approach is inspired by the idea of Rapetti and Bossavit to define higher order Whitney forms and their degrees of freedom using small simplices. We show that higher order differential forms on cubical meshes can be defined analogously using small cubes and prove that these small cubes yield unisolvent degrees of freedom. Significantly, this approach is compatible with discrete exterior calculus and expands the framework to cover higher order methods on cubical meshes, complementing the earlier strategy based on simplices.
Robust delay-dependent H∞ control of uncertain time-delay systems with mixed neutral, discrete, and distributed time-delays and Markovian switching p…
2011
Author's version of an article published in the journal: IEEE Transactions on Circuits and Systems I: Regular Papers. Also available from the publisher at: http://dx.doi.org/10.1109/tcsi.2011.2106090 The problem of robust mode-dependent delayed state feedback H ∞ control is investigated for a class of uncertain time-delay systems with Markovian switching parameters and mixed discrete, neutral, and distributed delays. Based on the LyapunovKrasovskii functional theory, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities for the stochastic stability and stabilization of the considered system using some free matrices. The desired control is …

Organizzazione dei rapporti commerciali tra imprese e “contratti relazionali”
2019
Il contributo ripercorre brevemente il superamento della visione atomistica dello scambio istantaneo e il progressivo riconoscimento delle specificità dei contratti di durata. In particolare, ci si sofferma sulla variabile “tempo”, in quanto questi ultimi si differenziano dallo scambio a esecuzione istantanea e dal contratto sottoposto a termine poiché lo svolgimento del rapporto per un periodo più o meno lungo è funzionalmente connesso all’interesse delle parti alla continuità dell’esecuzione. Movendo dalla teoria nordamericana dei relational contracts, gli Autori illustrano i mutamenti giurisprudenziali e dottrinali intervenuti nel sistema italiano. In particolare, sempre con riferimento …
Jauni ieskati kvantu automātu stāvokļu skaita efektivitātē
2022
Kvantu galīgi automāti var sasniegt eksponenciālu stāvokļu skaitu efektivitāti, salīdzinot ar determinētiem galīgiem automātiem. Viena problēma, kurā ir zināms, ka kvantu galīgiem automātiem ir eksponenciālas priekšrocības, ir MODn problēma, taču nav zināma metode, kā uzkonstruēt tādu kvantu automātu. Šajā darbā eksponenciāli efektīvie MODn algoritmi tiek vispārināti jaunā algoritmā, kas samazina vajadzīgo stāvokļu skaitu. Jaunā algoritma saaistības ar esošiem virzieniem literatūrā tiek aprakstītas, un tiek piedāvātas divas jaunas skaitļu virknes, kuras varētu izmantot, lai uzkonstruētu tādus kvantu automātus.
Discrete exterior calculus for photonic crystal waveguides
2022
The discrete exterior calculus (DEC) is very promising, though not yet widely used, discretization method for photonic crystal (PC) waveguides. It can be seen as a generalization of the finite difference time domain (FDTD) method. The DEC enables efficient time evolution by construction and fits well for nonhomogeneous computational domains and obstacles of curved surfaces. These properties are typically present in applications of PC waveguides that are constructed as periodic structures of inhomogeneities in a computational domain. We present a two-dimensional DEC discretization for PC waveguides and demonstrate it with a selection of numerical experiments typical in the application area. …
Automated detection and localization system of myocardial infarction in single-beat ECG using Dual-Q TQWT and wavelet packet tensor decomposition
2020
Background and objective. It is challenging to conduct real-time identification of myocardial infarction (MI) due to artifact corruption and high dimensionality of multi-lead electrocardiogram (ECG). In the present study, we proposed an automated single-beat MI detection and localization system using dual-Q tunable Q-factor wavelet transformation (Dual-Q TQWT) denoising algorithm. Methods. After denoising and segmentation of ECG, a fourth-order wavelet tensor (leads × subbands × samples × beats) was constructed based on thediscretewavelet packet transform (DWPT), to represent the features considering the information of inter-beat, intra-beat, inter-frequency, and inter-lead. To reduce the t…
