La legge di gravitazione universale (Polimi Open Knowledge)

/by

La forza di gravità è ciò che dà la forma ad ogni oggetto e corpo presente nell’Universo. I pianeti stessi e le loro orbite sono soggetti a questa forza tanto potente quanto misteriosa, come scoprirete seguendo queste lezioni.
Grazie a questo corso potrete apprendere al meglio i punti di forza e di debolezza della legge di gravitazione Universale: dopo un breve excursus inerente ai grandi scienziati del passato, verranno studiate le tre leggi di Keplero, per poi arrivare alla forza di gravità di Newton e alle teorie contemporanee. Lo studente, avendo preso confidenza con i concetti fisici che stanno alla base della legge di gravitazione Universale, sarà invitato a riflettere sul come sfruttare la forza di gravità a suo favore: “Come è possibile che gli aerei riescano a volare?””, “Come è riuscito l’uomo ad uscire dall’atmosfera?”. La magia verrà svelata!

Sensori di immagini e misure senza contatto (Polimi Open Knowledge)

/by

L’osservazione del cielo notturno ha da sempre affascinato l’essere umano, anche ai giorni nostri, la visione di un cielo stellato suscita in noi meraviglia. Oggi disponiamo di strumenti che ci permettono di andare oltre la mera osservazione a occhio nudo e scrutare così in profondità gli oggetti celesti: il telescopio e la fotocamera digitale. In questo corso ne analizzeremo il funzionamento: vedremo come, grazie al telescopio, siamo in grado di catturare la luce di oggetti celesti estremamente deboli e, tramite la fotocamera, possiamo imprimere questa luce nei pixel che compongono un’immagine digitale.
Ci accorgeremo che un’immagine così ottenuta necessita di una fase di post-elaborazione, al fine di risaltare al meglio i dettagli del soggetto ripreso: vedremo come ciò sia possibile tramite un processo che prende il nome di calibrazione dell’immagine.
Infine, scopriremo come questi scatti possano essere utilizzati nell’ambito scientifico delle misure, per studiare il moto degli oggetti celesti, la loro luminosità e il loro spettro elettromagnetico.

Deep renovation for energy efficient residential buildings (Polimi Open Knowledge)

/by
This course introduces the basics of deep renovation in residential buildings, though some modules apply to any kind of building. The student will be able to get a grasp of energy efficiency in buildings, and how to achieve a deep renovation project based on passive and active technologies.This course is intended to teach and form a new generation of skilled practitioners for a sustainable built environment. It welcomes students of any built environment discipline and overall, to any professional in the construction sector (designers, engineers, architects, developers, contractors, facility managers).To impact the uptake of the practice of deep renovation, the course has been framed within the European multilingual classification of Skills, Competences and Occupations ESCO, to ensure that the skills and knowledge on energy efficiency and deep renovation acquired in this course are identifiable across the European construction sector.The course is delivered in video format, and the audios have been transcribed (in English) to facilitate learning accessibility and to allow flexible learning methods (ref. Universal Design for Learning principles).

Introduction to nuclear (Polimi Open Knowledge)

/by

The study of static and dynamic properties of nuclei constitutes a first essential step in the comprehension and exploitation of Nuclear Science. Starting from the experimental evidence of radioactivity, the course will explore:

  • the physical and the random nature of radioactive decay and nuclear reactions;
  • the experimental methods and detector technologies to measure radiations produced by nuclear processes.

To better explore the topic, we will enter in POLIMI Labs to look at the working principles of the detectors employed in gamma-ray spectrometry. Also, we will see how nuclear reactions can be exploited to detect the presence of neutrons and to measure their energy.
Finally, we will see the main procedures used in radiochemistry to perform destructive analysis, useful When nuclei are hard to measure.

Control and replan using Earned Value and Risk (Polimi Open Knowledge)

/by

Project Management is a fundamental theme to understand and work in any business environments. Once projects are properly planned, the job of a Project Manager is just started. Indeed, PMs need to properly control, re plan, and manage risks during the execution of the project. During the course, the Earned Value Management System – the standard and most diffused technique to properly manage time and cost in a project – is presented. In doing so, the concepts of BCWS (the time-phased budget), the BCWP (the earned value) and ACWP (the actual costs of what has been performed) are introduced along with the main indicators that help managers in taking decision on how to replan the projects according to the estimation at completion. Finally, the main approaches to identify and manage risks are introduced along with the closing phase.

Life cycle and project planning (Polimi Open Knowledge)

/by

Project Management is a fundamental theme to understand and work in any business environments. One of the main skills that Project Managers need to have deals with the ability to manage the project during its entire life-cycle and to plan the work needed to achieve the final result. During the course, the various phases of a typical project are presented. Then, various practical tools are presented aiming to help professionals in actually manage their projects through useful instruments. Among the others, the Scope Statement helps managers in identifying and clearly define what is and what is not part of the project, the Work Breakdown Structure (WBS) helps in identifying the activities, the Organizational Breakdown Structure (OBS) in managing the team, the Responsibility Assignment Matrix (RAM) to match activities and people, while the Gantt Chart provides a time-based view on the project.

Project Management beyond planning and control (Polimi Open Knowledge)

/by

Project Management is a fundamental theme to understand and work in any business environments. Projects are the organizational way to make innovation happen and to realize any kind of custom solution or to change how an organization work. Project Management is the set of capabilities, skills and tools to properly work on projects. The course aims to define the concept of a project and to show how, in the management of a successful business, project management and process management must coexist and integrate. During the course the project is analyzed as a managerial tool for the management of change and innovation and its links with the company strategy are emphasized.

Ethics of Artificial Intelligence (Polimi Open Knowledge)

/by

The MOOC deals with the problems created, aggravated or transformed by AI. It is intended to give students a chance to reflect on the ethical, social, and cultural impact of AI by focusing on the issues faced by and brought about by professionals in AI but also by citizens, institutions and societies. The MOOC addresses these topics by means of case studies and examples analyzed in the light of the main ethical frameworks.

This MOOC is one of the MOOCs of the series titled “Introduction to Artificial Intelligence”, aimed at providing technical and non-technical, including historical and political, notions on artificial intelligence. The series investigates why artificial intelligence is nowadays considered the most disruptive enabling technologies up to at least 2050 and gives basic groundings for a preliminary approach to the area. It also deepens ethical issues and national strategies.
