Generative artificial intelligence (GenAI) is a complex and compelling machine learning technology that has sparked widespread social debate about its limits and possibilities. An analytical view from media ecology offers a remarkable framework to identify interrelationships between this emerging technology's problems and challenges. This article delimits the features of GenAI as a medium attached to media ecology and resorts to the conceptual tools of the laws of media (Four Effects) put together by Marshall and Eric McLuhan to reflect on creative work in the era of automation: amplification (or enhancement), obsolescence, retrieval, and reversal. Among the issues addressed are the implications of Gen AI as a technology for encoding representations, the loss of referentiality and traceability of works, the future of intellectual property and its impact on creative industries, and the return and revaluation stand out of shared experiences or performance.

Internal combustion engines are complex machines that constitute an object of design, and in which diverse processes and variables encounter. In the industrial field, the design of a new engine begins with the conception of a wellestablished solution with consideration on the experience of the designers. To perform the structural design of an engine, it is needed to determine the forces and moments acting on its components, derived from the processes along the cycles of work, with observation of the variations of the pressures and the temperatures in the cylinder and of the forces and moments of inertia in the components of the mechanisms and the structure. It is the purpose of the present paper to introduce the development of a series of procedures to obtain the preliminary dimensions of the main components of an engine (power mechanism, engine block and cylinder head dimensions), applying the machine design fundamentals and the thermodynamic and dynamic characterization of a generic engine of combustion, using the minimum information (power, torque, engine speed, and conditions of exploitation). To systematize the engine preliminary design, a spreadsheet based on Microsoft Excel was developed. To use this spreadsheet, the user must specify composition of the fuel, the type of ignition, and the wished characteristics of the engine. The outputs of the spreadsheet are the global stoichiometric balance of fuel-air chemical reactions, the heat release rate, the indicator diagram, the forces and moments acting on the main components of the crank-train mechanism, such a valuable information required to conduct the dimensioning of the engine components making use of the fundamentals of strength of materials.
