La musica
No full textNell'ambito della pubblicazione per l'opera inaugurale della stagione 2024-25 (il Sant'Ambrogio alla Scala, occasione artistica e istituzionale di levatura non solo nazionale) lo scritto - obbligatoriamente stringato per funzione - ha fornito una descrizione dei contenuti musicali della celebre opera verdiana accentuando di essi, per scelta dell'estensore, la dimensione schiettamente drammatica intessuta sulla base delle campiture sceniche che Giuseppe Verdi - innovativamente - prese a riferimento nel concepirla e nel darle forma
Bassorilievo con Alessandro e Aristotele
No full textLa cosiddetta Scala dei Giganti, eretta dal 1485 per accedere alla facciata orientale del cortile di Palazzo Ducale a Venezia, mostra una lesena in cui compaiono due teste identificate con Alessandro e Aristotele. La testa di Alessandro presenta un elmo conformato a scalpo di elefante, secondo una iconografia comune nella mnonetazione di età tolemaica; quella di Aristotele è una testa di invenzione con evidente caratterizzazione fisionomica, e allude forse a qualche personaggio della Venezia dell'epoc
A scalable infrastructure for teaching concepts of programming languages in Scala with WebLab: An experience report
No full textIn this paper, we report on our experience in teaching a course on concepts of programming languages at TU Delft based on Krishnamurthi's PAPL book with the definitional interpreter approach using Scala as meta-language and using the WebLab learning management system. In particular, we discuss our experience with encoding of definitional interpreters in Scala using case classes, pattern matching, and recursive functions; offering this material in the web-based learning management system WebLab; automated grading and feedback of interpreter submissions using unit tests; testing tests to force students to formulate tests, instead of just implementing interpreters; generation of tests based on a reference implementation to reduce the effort of producing unit tests; and the construction of a product line of interpreters in order to maximize reuse and consistency between reference implementations.Programming Language
Machine Learning-based optimization and PIV analysis of the active control of a cylinder wake via synthetic jets
No full textThe aim of the present paper is the investigation of the Synthetic Jet (SJ) based control of a cylinder wake through Linear Genetic Programming
(LGP) technique and the flow field via Particle Image Velocimetry (PIV)technique. Machine Learning is a branch of Artificial Intelligence aimed
at extracting knowledge and experience from big volumes of data and it is the art of building models from data using optimization and regression
algorithms. A SJ is an actuator used mainly for flow control and heat transfer performances. In this work, a loudspeaker attached to an hollow
cylinder is used as SJ actuator device and the optimization procedure regards the input signal sent to the device. A gradient-enriched machine
learning control, know as gMLC algorithm, is used as optimization tool. A preliminary phase of analysis of the ML algorithm, in which an optimal
control law is found, is conducted. The latter allows to obtain a very complex control law which is able to give a percentage drag reduction of 7.6 %
with respect to the natural case and this reduction is found to be better than the one obtained by a reference sinusoidal signal characterized by a
fundamental frequency of 44 Hz. After the ML analysis, an investigation via Particle Image Velocimetry is performed with the aim of of obtaining
a comparison between the natural case, i.e. the uncontrolled configuration, and two different controlled cases: the optimal waveshape obtained
via gMLC algorithm and the previous-mentioned sinusoidal waveshape

Multicarrier energy systems
No full textIn recent years, the power system studies changed dramatically, shifting their focus from power system expansion planning as well as operation quality enhancement to other issues such as the integration of large amounts of renewable resources, the definition of new roles for the Transmission System Operator and Distribution System Operator since more and more generation is moving on the distribution side, resiliency of grids and economic sustainability of the on-going revolution in the energy field.
Most energy infrastructures in the world were developed in the second half of the 20th century. The main question in energy system planning and development is whether these old systems can meet future growing needs for different types of energy carriers or not. Along with composite energy transfer systems, many of the installed equipment and tools are getting close to their useful lifetime or their relevant operational limitations. In addition, challenges such as the continuous growth of energy demand, still a strong dependence on fossil fuels, the need for power system reinforcement and the deep penetration of clean and sustainable energy resources raise the need for a new vision of energy systems along with some basic changes in existing systems.
Adopting the distributed generation units as well as gas-fired power generation technologies such as combined heat and power units or combined cooling, heat and power units, gas furnaces, gas converters, etc., in an energy hub has motivated applied research to investigate how to integrate different infrastructures such as electricity, natural gas and heat. The resulting system, called multienergy carriers, hybrid systems or combined energy systems, requires the application of new and integrated modelling as well as operation tools.
Possible scenarios for the future of the energy systems have been developed to overcome limitations of current structure due to a stronger interaction among different infrastructures (for example, gas and electricity). Many studies were oriented to guarantee standard levels of voltage and frequency in electrical systems or standard gas pressure in pipes in presence of increasing gas and electrical loads. Although these studies provided important details for the systems under investigation, they often propose solutions in line with existing reality and limit the analysis in finding an optimisation of the existing system without considering the possibilities deriving from different architectures. Modern energy systems, nowadays, must consider the coexistence of multiple carriers of energy, and, in the future, the concurrent planning and operational optimisation of them can provide an effective approach for improving economical performances, increasing sustainability and ensuring a secure and resilient operation.
This chapter will present some modelling and optimisation issues of strongly interacting energy systems and explore the possibility offered by multicarrier energy systems to improve the overall efficiency of coupled systems
Optimising the Stability in Plan Repair via Compilation
No full textPlan repair is the problem of solving a given planning problem by using a solution plan of a similar problem. Plan repair problems can arise in execution contexts, that is, when an agent performing the plan has to deal with some unexpected contingency that makes the given plan invalid. Repairing a plan works often much better than replanning from scratch, and is crucial when plans have to be kept stable. There is no planning system until now that guarantees to find plans at the minimum distance from an input plan. This paper presents the first approach to such a problem; we indeed introduce a simple compilation scheme that converts a classical planning problem into another where optimal plans correspond to plans with the minimum distance from an input plan. Our experiments using a number of planners show that such a simple approach can solve the plan repair problem optimally and more effectively than replanning from scratch for a large number of cases. Last but not least, the approach proves competitive with LPG-ADAPT
