PROGETTAZIONE DI IMPIANTI DI CONVERSIONE ENERGETICA
(objectives)
The main aim of the Energy Conversion Plant Design Course is to provide the student with the knowledge and technical and practical skills for the design and development of plant solutions aimed at producing energy that can be used for both civil and industrial. The expected learning outcomes are the knowledge of the criteria and sizing procedures of systems that base their operation on heat exchange dynamics such as ovens, heat exchangers, thermal systems, condensers, evaporative towers, steam generators and geothermal systems with heat pumps for both vertical and horizontal probes. Theoretical and practical notions associated with the realization of an industrial plant scheme will be provided, in addition to the the operation criteria and the choice of an actuation system for industrial applications or flow interception (such as valves). During the Course, purely applicative issues relating to multi-physics simulation software will also be addressed, useful for solving complex and multidisciplinary problems in the industrial sector.
Among the expected learning outcomes there are therefore the knowledge and the development of a critical sense in terms of the ability to identify the parameters associated with the operation of the aforementioned equipment in order to optimize its operation both in the sizing phase and in the activity phase (if possible), in relation to the requests of the final user, thus developing a critical sense from a technical point of view, as well as understanding the meaning of the technical terminology as used in the industrial energy plant sector, in relation to technologies and processes. At the end of the course, the student will have practical and theoretical notions relating to the aforementioned energy conversion systems, strengthening the skills already developed in the three-year degree program and having the ability to solve problems relating to even new issues or that require multidisciplinary approaches, in any case deriving from the sector under study. At the end of the course, the student will be able to communicate their conclusions clearly and unambiguously to specialist and non-specialist interlocutors operating in the energy conversion systems sector. In addition, the expected results include the student's development of a learning ability that allows him to deepen the issues addressed independently, adapting to the needs he will encounter in the workplace.

ENVIRONMENTAL MONITORING
(objectives)
The course aims at enhancing the comprehension of natural environmental processes and at introducing major traditional and remote environmental sensing techniques. The course provides concepts and methodologies to address the monitoring of major environmental variables.
The course aim is the knowledge of hydrological processes monitoring. Specifically, the course will focus on instrumentations and sensing techniques useful for observing environmental parameters.
It is possible to identify three main aims:
Refresh of notions about hydrological processes and their modelling, with particular emphasis of river discharge and precipitations.
Learning about instruments and sensing techniques for hydrological observations.
Learning and applying innovative approaches based on image analysis.
Expected outcomes following the Dublin descriptors:
Knowledge and understanding.
hydrological phenomena, specifically, rainfall and runoff formation. Common practice of data collection and measurements in hydrology.
Applying knowledge and understanding
The concepts with a more technical and applicative implication (tools and approaches for the measurement and estimation of hydrological variables) will be consolidated through both traditional (exercises) and advanced (small experiments to be developed independently) practical labs.
Making judgements - Communication skills - Learning skills
Students will be asked to develop a project that,in addition to provide a practical example for estimating river flow velocity, will allow them to investigate on the role of the image analysis. The project will be assigned without a rigid scheme, students will be invited to identify a scientific question on which they can investigate with the software application. During the project they will identify the answer to the scientific question and motivate their conclusions. Setting small groups and interacting with the lecturer will stimulate Making judgements - Communication skills - Learning skills under the hydrological perspective.
