- The Frankenstein Paradigm: More than Human, Less than NothingPublication . Castro, Paulo Alexandre eThis paper begins with the examination of some premises of Mary Shelley's novel, Frankenstein or the Modern Prometheus, and briefly revisits some of the concepts or ideas that she had adapted and that will allow to determine the premises that characterize what we named as Frankenstein Paradigm. Such a paradigm, as we suggested, allows us to perceive, on the one hand, the avant-garde vision of Mary Shelley about human condition (regardless of literary immersion in gothic subjects), and on the other hand, the complexity of themes that would mark what is termed by post-human, that we will give some examples whether in contemporary art or in the framework of figures and representations of daily life (some illustrations on movies will be given). In this regard, we will notice the prosthetic transformations that have already occurred and, therefore, to verify the practical application of the premises contained in the Frankenstein paradigm. Next, it is necessary to carry out a reflection on the ethical and social implications posed by post-humanism as the well-known paradox of the ship of Theseus (which, as we all know, illustrates the problem of identity).
- Comparative study of a clean technology based on DSF use in occupied buildings for improving comfort in winterPublication . EZE, Conceicão; Gomes, João; Lúcio, Maria Manuela Jacinto Do Rosário; Conceição, Maria Inês; Awbi, HazimThis paper presents a comparative study of a clean technology based on a DSF (double skin facade) used in winter conditions in the occupied buildings comfort improvement, namely the thermal comfort and air quality. The performance of a solar DSF system, the building’s thermal response, the internal thermal comfort and the internal air quality are evaluated. In this study, a DSF system, an air transport system and a HVAC (heating, ventilating and air conditioning) system based on mixing ventilation are used. The study considers a virtual chamber occupied by eight persons and equipped, in the outside environment, by three DSFs. A new horary pre-programming control methodology is developed and applied when the airflow rate is constant and the number of DSFs to operate is variable, when the airflow rate is variable and the number of DSFs to operate is constant and when the airflow rate is variable and the number of DSFs to operate is variable. This work uses a numerical model that simulates the integral building thermal behavior and an integral human thermal response. The internal air, provided by a mixing ventilating system, is warmed using the DSF system. The air temperature inside the DSF system and the virtual chamber, the thermal comfort level using the PMV index, the internal air quality using the carbon dioxide concentration and the uncomfortable hours are calculated for winter conditions. The results obtained show that the energy produced in the DSF, using solar radiation, guarantees acceptable thermal comfort conditions in the morning and in the afternoon. The indoor air quality obtained at the breathing level is acceptable. It is found that the airflow rate to be used is more decisive than the DSF operating methodology. However, when a solution is chosen that combines a ventilation rate with the number of DSF to operate, both variables throughout the day can obtain simultaneously better results for indoor air quality and thermal comfort according to the standards.
