1. On a Benchmark in Output Regulation of Non-Minimum Phase Systems

Author

Cecconi, Alessandro, Bin, Michelangelo, Bernard, Pauline, and Marconi, Lorenzo

Abstract

Output regulation for non-minimum phase nonlinear systems is still a largely open problem, with only a few results in the literature covering a few specific cases. This paper explores the design of a state-feedback regulator for a basic non-minimum phase benchmark system that, nevertheless, already embodies many of the challenges and difficulties linked to the lack of minimum phase. Although the developed solution only provides local regulation guarantees for this specific benchmark, it nonetheless suggests a path for the successive development of a systematic regulation theory for non-minimum phase systems in normal form. In turn, this paper is a first step in such a direction.

4. Fine's Monster Objection Defanged.

Abstract

The Monster Objection has often been considered one of the main reasons to explore non-standard mereological views, such as hylomorphism. Still, it has been rarely discussed and then only in a cursory fashion. This paper fills this gap by offering the first thorough assessment of the objection. It argues that different metaphysical stances, such as presentism and three- and four-dimensionalism, provide different ways of undermining the objection. [ABSTRACT FROM AUTHOR]

Abstract

Objectives To provide an epidemiological framework of symptoms related to Foreign Body (FB) injuries due to Button Battery (BB). Methods Data on BB ingestion/inhalation have been obtained from the ButtonBatteryDB. The ButtonBatteryDB is a database collecting information on BB injuries in children (0–18 years of age). Data on 348 BB injures have been derived from the Registry of Foreign Body Injuries “Susy Safe” (269 cases) and from published scientific literature reporting case reports of FB injuries (79 cases). Results Most of injured children were male and BBs were found more often in the mouth/esophagus/stomach (ICD935) and in the nose (ICD932). Analyzing symptoms related to BB located in the esophagus/mouth/stomach, we found that children had higher probability of experiencing dysphagia (30.19%, 95% C.I. 17.83–42.55), fever and cough (26.42%, 95% C.I. 14.55–38.28), compared to the other symptoms. Referring to the probability that symptoms occurred simultaneously, fever and cough are more likely (3.72%, 95% C.I. 1.0–6-43) to jointly showing up in children with BB in mouth/esophagus/stomach (ICD935), followed by fever and dysphagia (2.66%, 95% C.I. 0.36–4.96) and by fever and irritability/crying, fever and drooling, dysphagia and irritability/crying (2.13% C.I. 0.00–4.19, 95% C.I.) Conclusions These findings provide new insight in clinical presentation of BB injuries: the identification of unique patterns of symptoms related to BB injuries is useful to perform an early diagnosis (and to guarantee a prompt medical reaction), also when the injury is un-witnessed.

15. The use of acupuncture in the emergency room.

Author

Cecconi, Alessandro

Abstract

Emergency Room (ER) doctors have to deal with sever health conditions that require swift intervention, usually with rapidly-acting drugs. There may appear to be no space for traditional Chinese medicine (TCM) -- and acupuncture in particular -- in this context, thanks to the widespread belief that this kind of traditional medicine requires more time to act. This article describes the use of TCM in an ER in Italy. Through the description of several cases the author shows that acupuncture can be effective either alone, or in combination with Western medicine, for both diagnosis and treatment of conditions not normally ween in private TCM clinics.

16. Task-driven optimization of production networks

Author

Cecconi, Alessandro, thesis supervisor: Melchiorri, Claudio, Cecconi, Alessandro, and thesis supervisor: Melchiorri, Claudio

Abstract

Efficient scheduling of production systems is a critical task in modern manufacturing industries. This master thesis focuses on addressing the scheduling problem in production systems that involve a network of plants sharing production capacity. The complexity of this problem is further compounded by the need to consider client preferences, adding a layer of intricacy to the optimization process. Given that the scheduling problem is known to be NP-Hard, traditional methods often fail to provide satisfactory solutions within reasonable time frames. In this work, we propose a novel approach based on a iterative multi-objective Bipartite Matching algorithm to optimize scheduling in production systems with shared capacity and client preferences. The objective is to simultaneously minimize production delays and maximize customer satisfaction, taking into account various production constraints and preferences of the clients. We show how, given a particular network of facilities and a set of products to deliver, we can efficiently compute Pareto optimal scheduling solutions.
