An Innovative Mission Management System for Fixed-Wing UAVs
No full textThis paper presents two innovative units linked together to build the main frame of a UAV Mis- sion Management System. The first unit is a Path Planner for small UAVs able to generate optimal paths in a tridimensional environment, generat- ing flyable and safe paths with the lowest com- putational effort. The second unit is the Flight Management System based on Nonlinear Model Predictive Control, that tracks the reference path and exploits a spherical camera model to avoid unpredicted obstacles along the path. The control system solves on-line (i.e. at each sampling time) a finite horizon (state horizon) open loop optimal control problem with a Genetic Algorithm. This algorithm finds the command sequence that min- imizes the tracking error with respect to the ref- erence path, driving the aircraft far from sensed obstacles and towards the desired trajectory

Prophecy, prophets and the problem of truth in Latin late Antiquity and the early Middle Ages
No full textBetween the 4th and 9th century AC, many Latin Christian thinkers explore the nature and possible definitions of ‘prophecy’ from a philosophical point of view. The two main theories are found in the works of Augustine of Hippo and Gregory the Great, who agree on the idea of prophecy as «divine message», but diverge on the role of the prophet, who for the former is an interpreter with an active role, for the latter is a medium of the message rather than its author. Gregory’s theory seems to be more common – being more easily understandable – in the Early Middle Ages.
All thinkers quoted in the essay (apart from Augustine and Gregory, Cassiodorus, Isidore of Seville, Alcuin of York and Rabanus Maurus) also deal with the problem of truth in relation to prophecy and prophets: is there a criterion with which to establish with certainty who is a real prophet and who is a false one? This article attempts to demonstrate, on the basis of the De doctrina christiana of Augustine and of the Liber visionum of Othlo of Sankt Emmeram, that one of the signs of the truthfulness of a true prophet could well be the nature and form of language he uses
On a Functional Identity Involving Power Values of Generalized Skew Derivations on Lie Ideals
No full textLet R be a prime ring, Qr its right Martindale quotient ring and C its extended centroid. Suppose that F is a generalized skew derivation of R, L a non-central Lie ideal of R, m,n,s≥1 positive fixed integers. If F(u)n(F(u)m-um)s=0for all u∈L, then there exists λ∈C such that F(x)=λx, for any x∈R, with λm=1, unless when char(R)=2 and R⊆M2(K), the ring of 2×2 matrices over a field K. We will also provide a generalization of the previous result for semiprime rings. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024
Postcombustion removal of N2O in a pulsed Corona reactor
No full textA method for the removing NO and N2O from a gas stream is provided. The method comprises providing flue gases having NO and/or N2O, introducing the flue gas stream into a pulsed corona reactor, and reacting the raw feed gases within the pulsed corona reactor with the following reactions: e+H2O→H+OH,N2O+H→N2+OH, and N2O+OH→N2+HO2. An apparatus for removing NO and N2O is also provided
HEALTH CHECK AND FARM EFFICIENCY: A COMPARATIVE ASSESSMENT OF FOUR EUROPEAN AGRICULTURAL REGIONS
No full textThe European Commission has always considered the Common Agricultural Policy (CAP) as a dynamic political tool that aims to link the agricultural sector with the evolving of the economic, financial, social and political dynamics that distinguish the Member States of the European Union. From this standpoint, the Health Check (HC) is much more than a simple assessment of the state of health of European agriculture; it is a drawing up of the “new rules” that are to manage the relations between farms and the market, on which the future efficiency and survival of the said farms and the production sectors that characterise entire European agricultural regions will depend. In this context, the aim of this paper is to present and analyse the "innovations" of the future CAP compared to the current subsidy management system. In particular, the impact of the modifications of the HC – relative to the methods for funding farms due to the transition to the regionalised Single (Farm) Payment Scheme (SPS) and to the new rates of modulation – on the competitiveness of farms specialised in certain production sectors of four European regions will be considered: Emilia- Romagna (IT), Kassel (DE), Anatoliki-Makedonia-Thraki (GR) and Ostra Mallansverige (SE). The assessment of the impact of the HC on the competitiveness of farms is made by taking the technical efficiency index, estimated by a DEA model, as a proxy for the capacity of farms to use factors of production to their best advantage with respect to the farming system adopted and hence to be able to be competitive with other enterprises in the same sector. At the same time, the analysis of the impact of the HC measures is carried out using the “generalised” Positive Mathematical Programming method in order to enable a comparison between European regions. The integration of the two methods applied to the data of the European FADN enables an in-depth assessment of the impacts and a critical evaluation of the goals that the Community reform proposal is expected to attain.Health Check, Single Farm Payments, Technical Efficiency Index, DEA model, Positive Mathematical Programming., Agricultural and Food Policy, Political Economy, Research Methods/ Statistical Methods, Q10, Q12, Q18,
